The -word Anthropology is of ancient date, and has always signified tke study of Man ; originally, of Man moral, and, later on, of Man physical. At the present time it comprehends both. We may almost say that Aristotle was the originator of it. He termed those Anthropologists who carried on dissertations upon Man. The word is found for the first time in the title of a work of Magnus Hundt, in 1501. It is frequently to he met with subsequently as synonymous with " a description of the soul," or of " a description of the body and soul, and of the laws which govern their union." In 1772, Diderot and D'Alembert defined it as "a treatise on Man." In 1778, Kant wrote a work on psychology, entitled "An Essay on Anthropology." Blumenbach takes it ia the acceptation we give it at the present day. In 1838, Serres assumed, at the Museum, the title of Professor of Anthropology, or of the Ifatural History of Man ; and M. Edwards, in. 1839, defined it as the knowledge of Man in his physical and moral relations. Here and there, however, we find it more or less misinterpreted. Physicians have published, under this title, encyclopaedias embracing at the same time anatomy, physiology, pathology, and hygiene. A 3 INTRODUCTION. chapter in Professor Karl Sclimidt's " Lettres Anthropologiques," written in 1852, is entitled " The Anthropology of the New Testa- ment, or Jesus Christ." Three years ago an author in the " Eevue des deux Mondes " employed it as a synonym for the " Eeproduction of the human figore on Grecian yases." But such differences of signification are no longer aUo-wable. The word has a meaning, stamped upon it hy the whole of Europe, which cannot he ignored ; it designates a science as well recognised and as definite as chemistry, astronomy, or social economy. Definition. Anthropology is the branch of natural history which treats of Man and of the races of Man. It may be summed up in the following definitions : " Anthropology is a science which has for its object the study of the human race, considered as a whole, in its separate individu- ahty, and in its relations with the rest of nature." — Br oca. " Anthropology is a science pure and concrete, haviug for its aim the thorough knowledge of the human group, considered : (1) In each of the four typical divisions — as to variety, race, species — compared with each other, and in relation to their respective ex- ternal conditions. (2) In its ensemble, and in its relations with the rest of the animal world." — Bertillon. " Anthropology is the natural history of Man, considered mono- graphically, as a zoologist studying an animal would understand it." — De Quatrefages. Such is an outline of the subject for our consideration. It com- prehends aU the points of view from which the enlightened naturalist would look, who desired to give a complete history of any animal, and of its settled varieties. He examines (1) Its external form, and its internal organs after death. (2) The functions of these organs during life. He notes how the heart beats, the lungs respire, the brain thinks. He ascertains whether the animal is a biped or a quadruped j how its functions of reproduction are per- INTEODTJCTION. 3 formed, what are the influences "by which it is governed, what the ■character of its food, what its hahits, its instincts, its passions. (3) Its particular mode of associatiag with those of its own species, such as the wandering life of the dingo of Australia, and the bison of America, or the sedentary life of the heaver and the ant. (4) Its method of conveying its meaning to a distance by more or less articulate sounds, as by the rapid friction of the wing-covers, or by the simple vibrations of the larynx. (5) Its migrations, whether voluntary or forced, periodical or spontaneous, owing to the pursuit of an enemy, or m consequence of a flood, or from change of climate. (6) Its numerous records. Archseology indeed gives us an insight into the habits of animals in bygone times, their migrations, the period at which they became domesticated by Man, and those species which have become extinct. The naturalist, in this way, is enabled to give some sort of description of each group, and of each of its divisions, and to dis- tinguish them from those to which they are the most closely allied. Then, by synthesis, he estabhshes their respective position in the classification of animated beings, and the family, genus, species, or variety to which they belong. Having made himself acquainted with the relations which his object of study bears to the rest of the animal kingdom, he proceeds to enter upon the higher path of philosophical inquiry. Programme. ■ The course which the anthropologist takes is equally clearly de- fined. His aims are the same, his method of proceeding is identical. His subject is a twofold one : (1) Man considered in his ensemble, so far as the group to which he belongs differs from, or is analogous to, contiguous groups in the class of mammalia with which he is in nearest relation. (2) The varieties of mankind, commonly caUed races, a word which has but little present significance as compared with that which will be accorded to it at a later period. AH the traits and characters with which the naturalist is occupied «quaUy engage his attention, and even with greater intensity. B 2 4 INTKODUCTIOK Certain cliaracters of his embryo state, of but trifling interest in the animal, possess in him a very high degree of importance. These characters may be classified under four principal heads, viz. (1) Physical, whether studied on the dead body or on the-- living. (2) Physiological, which have a particular name assigned to them, according as they have reference to the brain, or to the intellectual faculties and phenomena. (3) Characters resulting from the social condition. (4) Those having reference to history, archseology, language, &c. The mode of pursuing the investigation is precisely the same for Man as for animals. If our inquiries- respecting the latter require the most rigid scrutiny, what shall we say when the subject of them is ourselves ? Intuitive reasoning, ajjrioi-i reasoning, and other methods of a similar nature, should be altogether excluded. Whether we are determining Man's position on our planet, and the part which he plays at the head of organised beings ; whether he is the sole representative of a king- dom — the human kingdom — or is only the first of the order of Primates, the same processes of scientific investigation must be put in operation. M. de Quatrefages, one of the strongest defenders of human prerogatives, expressly tells us this : Man is an animal • he comes into existence, reproduces his own species, and dies. Memento te hominem esse / was an exclamation to the conqueroE of old. Method of Investigation. Man in his entirety — that is to say, in his physical and moral' relations, to quote W. Edwards — is the subject of anthropology^ No zoologist would dream of dividing the study of an animal into- two portions, and of entrusting them to learned men of dififerent orders, some limiting themselves to the anatomical and physio- logical characters of certain organs, others directing their attention only to the brain and nervous system. Neither should the study of Man, under the pretext that one portion possesses supreme importance over another, be divided between men of science and philosophers. Each would look at Man or animal from hia INTRODUCTION. 5 own particular point of view ; but the anthropologist and the naturalist should take a comprehensive view of the whole. To understand the working of a machine, one must study its system of wheels, and make ourselves acquainted with the mechanism and structure of similar machines. The organisation, whether animal or human, simple or complex, is governed hy the same general laws, is constituted of the same elements, and performs similar functions. Men's mode of life, of thought, and of association, is as important to know as their mode of walking or breathing. The cerebral mani- festations, in their infinite variety, are as much characteristic of races as the volume and quality of the brain distinguish man from the brute : they are two orders of facts which are inseparable. If the structure of the organ indicates its function, so the function ^nd its various manifestations indicate the organ. The body and the mind are as indissoluble as matter and its activity, or, as it used to be called, its properties. The field of anthropology, then, is immeasurably vast, and might be defined as "the science of Man and of mankind," according to James Hunt ; or " the biology of the human species," according to M. Broca. Numerous and varied are the subjects of general knowledge which it lays luider contribution ! Its more immediate domain is the comparative anatomy and morphology of Man and animals ; then the history of animals, and of mammalia in particular, and especially of the anthropoid apes ; then the different branches of medical science, notably physiology, of which psychology in health and disease forms part ; then that which has reference to nations, and consequently to travel, as ethnography, geography, history, language, and, lastly, prehistoric archasology. This is not all — law, the arts, literature, equally con- tribute their share. L(5on Guillard, barrister and anthropologist, who died at Buzenval, demonstrated, eight months previous to his death, its intimate connection with the science of comparative law, a subject taken up by M. Acollas in 1874.* * " L'Anthropologie et I'ifitude du Droit compare," by L. Gnillard, iu " Bull. Soc. d'Anthrop.," 2ud series, vol. v. ; " L'Anthropologie et le Droit," by B. AooUas, in " Bull. Soc. d'Anthrop.," 2nd series, vol. ix. 6 INTKODUCTION. The year previously, M. C&ar Daly liad shown, before the Soci^t(5 d'Anthropologie, that architecture, ia its elementary forms, varies according to the distiactive character of each race. F^tis, in 1867, suggested a classification of races, based upon their musical systems.* Dances, songs, and national poems, like the heathen mythologies, serve to trace out their origin and affinities. The ' first attempts at anthropometry, for the purpose of determining the proportions of the human body, and craniometry, for analysing the physiognomy, are due to artists. We see, then, that anthropology appeals to all willing workers, whatever the direction of their studies or the nature of theiu pro- fessional occupations may be. All, with scarcely any preparatory study, may contribute to its progress ; it is sufficient to indicate tO' them its aim — the knowledge of Man. The mere word " anthro- pology " frightens many people, who imagine that it has to do with medicine. Medicine. The study of Man, relegated at first to the dissertations of philosophers, on assuming a real basis naturally became shared both by physicians and naturalists j the former, however, had but little leisure to deal with the special questions which it involved, while the latter were reluctant to regard it in the same light as they did that of the brute creation, which was the special subject of then- investigation. It was necessary that anthropology should be un- constrained. Both at the Museum and in the Faculty of Medicine of Paris, it has its representatives and its classes, but it holds a thoroughly independent position there. While medicine has especial reference to the individual — to the human machine — anthropology studies the human group and its varieties. The former has but one aspiration, one aim — the prevention and cure of disease ; the latter studies Man, his origin, and his relations with other animated beings, without troubling himself about the manner * "La Classification des Eaces," by F^tis Sen., in " Bull. Soc. d'Anthrop.," 2nd series, vol. ii., 1867. nsPTEODUCTION. 7 in which society ia general may treat the question. Their method of looking at things is altogether different. Is it a question of anatomy? Medicine looks at the organ in relation to adjoining parts, as it bears upon surgical operations, or at its structure, the better to understand whether its performance is regular or dis- turbed. Anthropology finds in it only elements of comparison with animals or between races. Is it a question of physiology, of pathology, of hygiene, or of therapeutics t They still diverge. The one seeks in the brain the method by which thought is elaborated, and how it is transformed into action ; the other sees in it only different manifestations, varying according to race. Diseases are not alike in aU latitudes. When it is a question of clitnate, it is specially in the province of medicine ; when of race, it is for anthropology to step in. So with respect to the action of remedies, each regards the question from its own particular point of view. Lastly, hygiene has a bearing upon anthropology, owing to the part which it plays, or its influence on external circumstances, acchma- * tion, or crossing. An acquaintance with the medical sciences, without being indis- pensable to every anthropologist, gives him a marked advantage. Reciprocally, a knowledge of anthropology invests the physician with a certain pre-eminence. It augments his interest in anatomical and physiological studies, and is the climax of academic study. "We are surprised, therefore, that instruction in it does not form part of the regular course in oui' principal faculties. Looking at it in connection with the healing art, it is indispensable that the medical men in our navy and mercantile marine, called upon, as they are, to practise among races the most diverse, should know how to distinguish them, as well as to recognise the varieties of local circumstances under which diseases present themselves. \ Ethnography. \ \ The word "ethnography" was employed at the commencement of the present century as synonymous with a description of nations. « INTRODUCTION. It was made use of in 1826 in the "Atlas GeograpMque " of M. Balbi, and was ratified under the influence of what was sub- sequently termed linguistics. Wiseman, in 1836, defined it as "the classification of races by the comparative study of languages ;" M. Broca, as simply the description of each nation in particular. The word "ethnology" had its origin in the title of the Society of Ethnology of Paris, in 1839. It embraces, as set forth in the statutes of that society, " the physical organisation, the intellectual and moral character, the language, and historical traditions which serve to distinguish races." It is used in the same sense in England by Prichard, Lubbock, Logan, Brace, ('The first ethnographical society of which there is any record was instituted in Paris in 1800, under the title of the "Society des Observateurs de I'Homme," and died of inanition during the war. The second was instituted in London in 1838, and was of an exclusively philanthropic character. The fact of the polygenists having declared that the black races are inferior to the white, was used as an argument in favour of slavery. The society should have set its face against this doctrine, and it suffered the penalty for not doing so. The following year, M. Edwards founded the Soci^t6 Ethnologique de Paris, which has furnished some excellent works, at the fore-front of which is to be mentioned a pamphlet by its founder, " Sur les Caractferes Physiologiques des Eaces Humaines considerees dans leur Eapports avec THistoire." Some admirable works soon appeared, both in France and elsewhere, having similar ethnographical views, among which we may mention, " L'Homme Am6ricain," by Alcide d'Orbigny.f In comparative anatomy, the skull, to which the labours of th& first anthropologists had been directed, continued to attract their attention. The " Decades " of Blumenbach were followed by others. la 1830, Sandifort published the first volume of his "Tabulae Craniorum Diversarum Gentium." In 1839 appeared the best work of its kind, the " Crania Americana," by Morton • and in 1844, his "Crania ^Egyptiaca." In 1845, the "Atlas de Cranioscopie," by Carus ; in 1856, the first volume of "Crania Britannica," by Davis and Thumam ; in 1857, the " Crania* Selecta," by Yon Baer, &c. Many others might be mentioned. * " La Lingai3tique," by M. Abel Hovelacque. 2nd edition, Bibliothfeque des Sciences Contemporaines. Paris, 1876. f " L'Homme Amerioain de I'Amerique Meridionals," by Alcide d'Orbiguy, Two vols. Paris, 1839. INTKODUOTION. 17 At Heidelberg, Tiedemann, known by his incomplete cubic measurements of the skull; ia Sweden, Eetzius, by his division ■of skulls iato long and short; ia Holland, Van der Hoeven; in Germany, Wagner, Huschke, Lucse, &c. The influence of such authorities as these somewhat encouraged anatomists in France to enter upon so unpopular a path of study ; and, besides Daubenton, we may mention Dureau de la Malle, DubreuU, FoviUe, Maslieurat- Lagemard, Pucheran, Lflut, Parchappe, Serres, Jacquart, Jouiiu. Anthropology, up to this time, did not exist as a separate science ; its efforts were of a restricted character ; it had no pro- gramme ; its name was mentioned only casually. It became of the utmost importance to centraKse all the studies bearing upon the natural history of Man and his races. This was the task ofi^^ Soci^t^ d'Anthropologie, which was founded in Paris in 1869,/ under the direction of Dr. Paul Broca, a professor of the Facility ■of Medicine, by a few savants, among whom may be mentioned Isidore Geofiroy Saint-HUaire, De Quatrefages, Gratiolet, Dareste, Ernest Godard, Charles Eobin, B^clard, &c. The society, con- ceived in the most liberal spirit, was composed of scientific men of every denomination, whether Kterary men or those devoted to the study of art, so that, if any question arose, it could be discussed by the highest authorities. Anthropology, which, in 1838, gave to the Museum the chair of the !N'atural History of Man, started on & new basis. Following the example of Paris, other cities founded societies bearing the same name: viz. London, in 1863; New York, St. Petersburg, and Moscow, in 1865; Manchester, in 1866; Florence, in 1868; Berlin, in 1869 ; Vienna, in 1870; Stockholm and Tiflis, in 1874. The date of the foundation of the society of Paris was coincident with two events of the highest importance : the public confirmation ■of the discovery of Boucher de Perthes, who traced back the antiquity of Man to a remote period; and the pubhcation of a work by Darwin on the " Origin of Species," which has contributed so much to give to the science of Man the impetus of which we are now the witness. It marks with distinguished significance the c 18 INTEODUCTIOK. oommencement of a new era. It is witli the facts and estaMisliedi opinions generally received at the present time that we propose to- deal in this volume. Many names have been omitted in this brief ' historical outline, which we shall hope to have an opportunity of supplyiug as we proceed. Plan of the Work. The plan of this work is a necessary sequence from what has been stated. Of the two branches of the study of Man — ^the one anthropology proper, which has to do with Man and his races, the other ethnology, which treats of nations — the former will alone occupy our attention. Our subject naturally divides itself into two parts. (1) The study of Man considered as a zoological group. (2) The study of human races as divisions of that group. In the first part we shall con- sider the three series of characters — the physical, the physio- logical, and the pathological— upon which natural history depends ; and in the second part, more particularly those to be deduced from archaeology, linguistics, and ethnography. In the iirst part we shall endeavour to show the relations which subsist between Man and animals, and shall consider a number of questions which have reference to medical studies, regard Man in his ensemble, and have an especial bearing on our subject. In the second part, after describing the characteristics which serve to distinguish races, we shall give a summary of the various physical types which the present improved state of science exhibits to us, and upon which the determination of races depends. In the third part we shall detail the various theories as to Man's origin. It wiU be necessary for us to say a few words, by way of intro- duction, as to the methods of zoological classification, and to give a description of the animals to which we shaU frequently have to refer. Zoological Classification, When the naturalist looks off from matters of detail, and con- templates the animal kingdom in its entirety, he is struck with the- INTEODUCTION. 19 small number of agencies at work to obtain the most diverse forms. He observes that in a general way there is a continual pro- gression from the simplest to the most complex organisms. He speaks of it, in other words, as " the general harmony of natme," " the plan followed by nature," " unity of type, of agreement in form, or of organic likeness." He compares the succession of beings to a ladder (Bonnet), to a chain, or to a tree with many branches. He has an intuitive impression, whether formulated or. not, that there is a succession and gradation in the different types of animals, as if some organic force were incessantly iu operation, modifying and increasing the number and variety of species. Cuvier, who feared to soar above facts, maintained, on the contrary, the doctriue of successive creations. He then abandoned it, and finally maintained, with Isidore Saint-Hilaire, that existing species are not descended from those of a bygone age.* "Whatever may be the secret of the origin of animated beings, it is certain that appearances seem to f avom the idea that they sprung originally from one another. Many gaps exist between - them ; but their niunber is daily decreasing, owing to unexpected dis^ coveries in the bowels of the earth, in the depths of the ocean, or in some hitherto unexplored corner of the globe. It has been repeatedly said : " Nature does not make sudden jumps." There is a successiveness observable throughout, especially in minutise. M. Ch. Martins and M. Durand (de Gros) have furnished us with examples of this.+ The method by which the fin is transformed into the bent limb, having one direction, as in the tortoise, or an opposite one, as in Man ; how it becomes divided into a longitu- dinal shaft, which is enlarged or reduced in. size, according as it . goes to form the leg of the dog, the wild boar, the horse, or -the. gorUla, is truly marvellous. Agassiz used to demonstrate to his audience at Hew York how * "Vie et Doctrine de B. GeofEroy Saint-Hilaire." Paris, 1847. t " Creation et Tranaformisme," by J. P. Durand (de Gros), in " Bull. Soo. d'Anthrop." 2nd series, vol. v., 1870 ; " Hommes et Singes," by ,L. Agassiz, in the "Bevue Scientifique," 2nd series, vol. iii..p. 818, 1874. c 2 20 INTEODUCTION. " by twisting this, and elongating that," one might form a fish, a reptile, a mammifer, or an ape, &c.* Hence the difficulties which naturalists experience in exactly circumscribing the limits of the divisions upon which their classi- fications rest, and of giving to each the proper name which be- longs to it. That which is family in one becomes order in another ; that which is genus becomes species, and vice versa. All depends upon the point of view from which they are regarded, and the particular opinion formed as to their characteristic features. In order to account for the disputes which are going on about Man, and the place which he occupies relatively to other beings, it is necessary that this should be thoroughly understood. In some, classifications depend upon clearly defined natural groups, which are recognised, though they cannot be strictly demonstrated. In others they are based upon certain groups shading off into contiguous groups. " Methods of classification," writes Daubenton, " have one principal defect which it is impossible to avoid, namely, that art takes a larger share in their arrangement than nature." "Classi- fications," says Lamarck, " are artificial methods ; nature has not really formed either classes, orders, families, genera, or unvarying species — ^but individuals only." Geoffroy Saint-HHaire, on his return from Egypt, alluded to them in these terms ; "A useful method, doubtless, but necessarily imperfect in its resources, and incomplete in its aim; true science ought to have higher aspirations." The illustrious opponent of Cuvier, who was about to publish a cata- logue of the Museum, which was a veritable classification, gave it up, although the proof-sheets were in the press. Nevertheless, classifications are valuable, and, indeed, indispen- sable. They assist study, bring together animated beings, generally in a natural way, and mark the measure of progress accomplished. In natural history we understand classification to mean the grouping together of beings according to their degree of probable relationship, based on the number and importance of their common characters. Thus, throughout the whole of the animal kingdom, one observes * " Hommes et Singes," by L. Agassiz, in the " Revue Soieutifiqne," 2ud series, vol. iii. p. 818, 1874. INTRODUCTION. 21 one principal special feature yrheiebj to establish, a primary division of four branches. From the presence or absence of a skeleton, ■whether internal or external, we distinguish Zoophytes, MoUusca, the Aiticulata, and the Vertebrata. "We may remark, before going farther, that zoophytes approximate in their inferior forms to cryptogams of the vegetable kingdom, but that now a new kingdom has been placed between them, formed of organisms stiU more . elementary, under the name of rbgne de protistes (Hseckel). From many characters, derived principally from the external covering, Vertebrata have been divided into four classes, viz. : EeptUes, Fishes, Birds, and Mammalia. Mammalia, again, are divided — according to the existence or non-existence of an external abdominal pouch, in which the young pass through the second phase of their development — into two sub-classes — the Didelphs and the Monodelphs. So far, the chief characteristics present modifications so funda- mental in the arrangement of the principal apparatus of the organism that, by virtue of the law of subordination of cliaracters, it is easy to confine oneself to a single one. The presence of an internal skeleton is proof of a special arrangement of the nervous system no less characteristic. Indeed we have no other choice than to divide Yertebrata in this way, and it is no less necessary as regards those next in the series. The more we descend in the sub- divisions of the former, the more the difficulty increases. We then have to consider many features in combination, and are not com- pelled to adopt any fixed plan. At each step the same uncertainty presents itself. What is the general characteristic of the group ? And is it reaUy the proper one ? Have we not created it ourselves, according to the distinctive feature we may fix upon 1 AU scientific classification is provisional and arbitrary, as long as a science is in course of development. Its province is chiefly to introduce some order into the medley of individuals it has under its immediate notice, to set up beacons, the correctness of whose guidance time wUl either establish or annul. Two groups being given, it is easy by laying hold of individuals the most dissimilar to distinguish two opposite types. But a certain number of indi- 22 IKTRODUCTIOK. viduals will always more or less deviate from them, and mil he blended -with, contiguous types altogetlier dissimilar. There are few secondary divisions in natural history which can he regarded as settled, and which might not he changed to-morrow. Thus, to the four classes of Vertebrata, many have added a fifth under the name of Batraehians, making them a distinct class from reptiles. So the Didelphs, one of the most correctly defined of the suh-classes, from being based on their habitat, have been displaced and abolished, most of them being classed with the Edentata or the Rodents, the remainder becoming a distinct order under the name of Pedimana. Species is the convenient zoological unit. We will define it in due course. On the one side we have varieties ; on the other, ■genera, families, &c. A genus is the assemblage of many species presenting certain poiats of connection ; a family, the assemblage of many genera, and so on. Between the genus and the species we sometimes have sub-genera ; between the genus and the family, the particTilar tribe we are in search of ; between the family and the order, the sub-order, &c. The number of genera in a family, or of species in a genus, is indeterminate. Mammalia. N"ow, in the class of Mammalia, the Didelphs include the Mar- supials (kangaroo, opossum) and the Monotremes (echidna, orni- thorhynchus). The Monodelphs include (1) The Cetacea and Amphibia. (2) The Pachydermata and Ruminantia. (3) The Edentata, the Rodentia; the Carnivora, the Cheiroptera, the Quad- rumana, and the Bimana — the Orders according to Cuvier. "We cannot enlarge further on this subject. In a special work on Zoology, published in the Bibliothfeque des Sciences Contem- poraines, will be found what the general opinion is as to these divisions. We have to do with the last two, and we shall discuss them according to theic relative importance. Linnaeus associated Man, the monkey, and the bat, in one and the same order, under the name of Primates. This purely zoolo- INTRODUCTION. £3 gical arrangement, wWcIl placed Man at the head of the' series of animated beings, greatly disturbed Bltimenhacli, Lac4p6de, Daii- henton, and Cuvier ; and in a spirit of reaction, as it would seem, duvier proceeded to isolate Man in a distinct order, and placed the monkey in another order, the bat in a third, &c. Two principal classifications are before lis, in which the distance which separates Man from his nearest zoological connections is •estimated differently. In one, Man forms a distinct order, in the same category as the ape or one of the Carnaria ; in the other, he forms merely one family in the order of Primates, the various divisions of the monkey tribe coming afterwards. Thus : Primates. First system of classification. — First Order : Man. Second Order: Apes. Third Order : Bats. Fourth Order : Dogs, Bears, &o. Second system of classification. — First Order : Primates. First ■Famihj : Man. Second Family : The higher Apes, or Anthropoids (the gorilla, the chimpanzee, the orang, and the gibbon). Tliird Family: The Monkeys of the Old Continent, or Pitheoians {semnopithecus, guenon, magot, cynocephalus [baboon]). Fourih Family : The Monlteys of the New Continent, or Cebians (howl- ing monkey, atele [spider monkey], sajou, ouistiti [marmoset]). Fifth Family : The Lemurs, Macauco, Galseopithecus.* * We draw atteBtion to the various Barnes in this list, to which we shall frequBBtly have to refer. In cnrreBt language we sometimes speak of the Anthropoids as the great apes or monkeys, and the Pitheoians and Cebians as the common or true monkeys. Frequently the epithet "Simian "will occur in like manner, as synonymous with monkey-like, particularly those of the first three families. Lesson united the Pitheoians and the Cebians, under the name of Simiades ; so that he had in the first order, or Primates, five families : the Hommidese, the AnthropomorphsE, the Simiadffi, the Lemuriens, and the False Lemuriens. Huxley divides Ms families into seven— namely : the Anthropini (man), the Catarrhini, the Platyrrhini, the Arotopithecini, or Marmosets, the Lemurs, the Cheiromyini, and the Galseopitheoi, or flying monkeys. Two of these appellations originated with Geoffiroy Saint-Hilaire, the Catarrhini, or monkeys of the Old Continent; and the Platyrrhini, or 24 INTRODUCTION. Second Order : Tlie Cheiroptera, or Bats. TJdrd Order : The Camaria. First Family : The Plantigrades Second Family : The Digitigrades, &c. Anthropoid Apes. We notice that the Lemurs, or iaferior monkeys, form the transition between the common monkey and various genera scattered through the succeeding orders. For example, between the family of Anthropoids, the Gibbon forms the connecting link with the Pithecians ; and some of the Cebians have a similar relation to the Lemurs. It is from these intermediate forms that we flU up the gaps in question. Which of these two systems of classification is the better 1 If we consulted only our own wishes, the answer would be an easy one. Each of us has the consciousness of being vastly superior to- the highest class of apes, and would desire that the separation should be as wide as possible ; but this is only a matter of feeling. It is a question of fact. Let us proceed then. The question re- solves itself into the following terms : monkeys of the New Continent, wiioli are distinguished by the structure of the nose. Others have understood the word " Catarrhini " to mean those without a tail (Anthropoids), or with a tail (Pithecians). The second classification which we have above summarised is that which M. Broca has- adopted in his memoir, " Sur I'Ordre des Primates," in 1869. Among the Anthropoids, the genus Gorilla is limited to a single species, the Gorilla Savagii, whose habits have been described by Paul du Chaillu. — (" Voyages et Aventures dans I'Afrique ifiquatoriale." Paul du ChaiUu. Paris, 1863. And " A Journey to Ashango Land," by the same author. Loudon, 1867.) Of the Chimpanzee, or Troglodytes, there are at least six species : the black, the most common ; the Aubryi, a specimen of which waa brought to France by Count Aubrey ; the Calvua, or bald ; and the Koolo- kamba, mentioned by M. du Chaillu ; the Schweinfurthii, from the rivers of the "White Nile ; and the Livingstonii, or Soko, from the banks of Lake Benguela. With the exception of the last two, all are to be found from the Gambia to the 13th degree of south latitude. The Orang-outang, or Simla, or Satyrus, includes two species : the Ruf us, or red-haired, of Borneo ; and the Bicolor, of Sumatra. Lastly, the Gibbon, or Hylobates, has numerous species, of which about ten have been described. The largest is the Siamang, or Hylobates Syndaotylua. INTEODUOTION. 25 What is the value of the characteristic points of difference be- tween Man and monkeys, and especially the anthropoid apes 1 Are these differences as great as those which separate two families or two orders 1 The nature of the reply will he dependent on the facts we are ahont to set forth in the following chapter, and which M. Broca proposes to call anthropologie zoologique.* * M. Broca, in tlie article in the "Diotionnaire Encycl. des Sciences Medicale," mentioned at page 8, divides anthropology as follows : (1) Zoo- logical anthropology, or the study of the human group considered in its relations with the rest of organised nature ; (2) Descriptive anthropology, or the study of the human group considered in its individual relations; (3) Greneral anthropology, or the study of the human group considered as a whole. On one occasion our esteemed master rehearsed to us his views somewhat as follows : Medicine studies individuals ; ethnography, peoples ; ethnology, races; and general anthropology, man in his ensemble, and in his relations with animals — this last constituting a particular section as zoological anthropology. Our objection is, that the denomination " zoological " relates as much to the part which treats of the human races as to that which treats of Man in general, and that we proceed by the same methods in both, the pre-eminence attaching to anatomical characters. We wish that ethno- logy were taken, according to its etymological sense, to express the general science of peoples, according to Frederic Miiller's method, and that the study and description of primitive races, regarded as natural divisions of the human group, were left to anthropology proper. (Seepages.) M. Broca in his system has considered ethnology as merely a branch of anthropology, which consequently should enter into the plan of this work; whilst in ours, ethnology, though furnishing numerous materials to anthropology, preserves an entire independence, and requires a distinct volume.

SKELETON AND SKULL IN GENERAL ZOOLOGICAL FACIAL ANGLE CBANIAL CAPACITY SITUATION AND DIBBCTION OP THE OCCIPITAL FORAMEN OCCIPITAL AND BIOBBITAL ANGLES. The characters of the human group are- of two orders : some organic, to be studied on the skeleton and on the dead hody ; others physiological, on the Kving. Among the former, those to be drawn from the skeleton occupy the first rank; the skeleton, in fact, determines the general form of the body, serves for the attachment of muscles, and marks out the boundaries of the visceral cavities. Osteologieal Considerations. The skeleton of Mammalia— the class of Vertebrata which will alone engage our attention — is composed (1) Of a central axis, con- stituted by the bodies of the vertebrae ; (2) Of a series of osseous arcs directed backwards, to form, by their aggregation, a large canal, in which are contained the brain, the cerebellum, and the spinal cord; (3) Of a series of arcs directed forwards, bounding certain cavities which are occupied, above by the organs of vision, smell, and taste — then by the central organs of circulation and the lungs — lower down by the digestive apparatus — and lower stUl by the organs of reproduction; (4) Of the appendages to various segments called extremities, the anterior serving, in a general way, for prehension, the posterior for locomotion.

Chap, i.] PHYSICAL CHAEACTEES. 31 The skeleton is composed in Man of one liundred and eighty- eight bones, exclusive of the patella, a small hone developed in the thick part of liie tendons of the principal extensor muscle of the thigh ; that is to say, twenty-six for the vertebral column, eight for the cranium, fourteen for the face, thirty-two for each of the superior extremities, and thirty for each of the inferior, &c. The twenty-six bones of the vertebral columji are divided thus : seven cervical vertebrae ; twelve dorsal ; five, and sometimes six lumbar ; five or six sacral bones, which, being anchylosed, form the sacrum ; and four or five caudal, which, more or less welded to- gether, form the coccyx. To speak correctly, the cranium is formed of three modified vertebrae, and is the true commencement of the vertebral column. Every vertebra, whether cervical, dorsal, or lumbar, consists (1) In the centre, of a foramen, through which the cord passes ; (2) Anteriorly, of a body, which is artictdated to those of the ver- tebrae above and below by a fibro-cartilaginous disc, called the intervertebral; (3) Posteriorly, of a spinous process, bifurcated in the cervical region, simple in the rest of the column, the bases of which are called laminae; (4) Of two transverse processes, attached to the body by two pedicles ; and (5) Of four articular processes, which serve to attach the vertebra to those above and below. The eight bones of the cranium consist of four middle and symmetrical — -the occipital, the sphenoid, the ethmoid, and the frontal ; and two lateral pairs — ^the parietal and the temporal. The middle portions of the occipital, the sphenoid, and the ethmoid represent the body of each of three vertebras. The large flat portion of the occipital, temporal, and frontal is called the squamous portion, or ecaille (shell). These bones come under the denomination of flat bones. They have an internal surface, which looks towards the cranial cavity, called by M. Broca mdocrdne, and an external surface. The body of the occipital (0, Kg. 2) is formed by the basilar process, which is united to the body of the sphenoid by an im- portant articulation, the basilar suture. Its surface is transversely divided by a semicircular ridge, for the attachment of the muscles 32 PHYSICAL CHARACTERS. [Chap. i. of the neck, the middle portion of which is occupied by the inlon, or external occipital protuberance; the portion above, or sur- occipital, is separated during a part of intra-uterine existence, and exceptionally in the adult, and is designated the interparietal, or sub-occipital bone. The portion below has a second curved line, also for the attachment of muscles.

All the portion situated below the temporal ridge, marked by the letters S D T constitutes the temporal fossa. At the union of the basilar process and the squamous portion is the occipital foramen, or foramen magnum of foreign authors, the middle, anterior, and posterior portions of which bear the names of basion and opisthion, the lateral portions being occupied by the occipital condyles, by which it is articulated with the first cervical vertebra, or atlas. Two irregularities in the bone sometimes exist, Chap, i.] PHYSICAL CHABACTEES. 33 namely, in front of the basion, an eminence which has been called the third condyle of the occipital ; and on the external part of the ordinary condyles, an eminence called the jugular process. The parietal hones (P) present nothing to paiticularise hut a pro- jection in the centre, which marks the centre of ossification, and takes the name of parietal eminence. The frontal bone (F) is divided externally into two portions — the superior and the inferior. The superior, or squamous, has at the sides two curved Unas, termed temporal ridges, which give insertion to the temporal muscle ; and, nearer the median line, two projections, termed the frontal eminences. The inferior, or sub-cerebral, belongs to the face, and presents from without inwards. (1) The external orbital processes, by which it is articulated with the malar bones, their sharp lower border forming the superior border of the orbits ; (2) Eidges, or superciliary arches, which correspond with the position of the eyebrows, and have a similar direction ; (3) A projection, or glabella, on the median hne. The median point, answering to the point of separation of the two cerebral and sub-cerebral portions, is called the point sus-orbitaire, or ophryon. The surface of the temporal (T) is divisible externally into three portions : a mastoid portion, forming the mastoid processes (B), to which powerful muscles are attached ; a squamous portion ; and a zygomatic portion. The zygomatic is simply a horizontal process, which arises by a root, or longitudinal crest, surmounting the audi- tory or auricular opening. A fourth portion is especially seen on the inferior and intracranial surface, called the hard or petrous portion, in which is enclosed the auditory apparatus. The sphenoid (S), so called on account of its being wedged in between the bones at the base of the skull, consists of a body, which at birth is formed of two portions, called anterior sphenoid and posterior sphenoid ; of two descending wings, or pterygoid processes, which form the boundaries of the posterior nares ; of two large ascending wings, of which the highest external portion is seen at S, Fig. 2 ; and of two lesser horizontal wings, which form part of the cranial cavity, where they separate the middle and anterior cerebral fossse. Viewed from above, that is to say from 34 PHYSICAL CHARACTERS. [Chap. i. the side of the cranial cavity, the body of the sphenoid presents an excavation, the sella turcica (L, Fig. 6), a transverse fissure, the optic fissure, and between the two a slight ridge, to which the Germans have given the name of ephippium. The ethmoid has special relation to the nasal fossae, and only has interest to the anthropologist from the side of the cranial cavity, where it impinges upon the median line between two portions IiZ2'T^'^'^°5^^^h "'' ™pra-ntvsal point, in the centre of the minimum frontal width MM ; N, Nasal point m the centre of the naso-frontal suture ; B, Nasal spine, ?fvpnl^;''Sif''°?*Ti --h- Middle point of the superior alveolar arch, or superior alveolar point ; S, Point of junction of the temporal ridge and the coronal suture or stephanion ; B, Position of the frontal eminences ; D, Maxillary bones ; J, Malar hones ; G, Anterior nares ; Z, Zygomatic arches ; F, Mastoid processes. of the frontal, by giving attachment to the crista gaUi and the cribriform lameUa, through which the filaments of the olfactory nerve pass from the cranial cavity into the nasal foss». The principal bones of the face are the nasal bones (N, Fig. 3), which unite with the frontal to form the naso-frontal suture at the root of the nose ; the superior maxillary bones (D), a prolonga- tion of which, called the ascending process, is articulated with the frontal at the sides ; the palate bones, which enter into the forma- tion of the roof of the palate behind; the malar, or jugal bones (J), Chap, i.] PHYSICAL CHARACTERS. 35 which project backwards, and at the side, at the junction of the temporal, to form a sort of bridge called the zygomatic arch ; and the inferior maxillary bone. The superior maxiUary bones are the principal bones of the face. At the sides they are articulated with the malar bones ; above, they form the inferior wall of the orbits ; internally they are united to the bones proper of the nose, and form the boundary of the anterior nares; below, they form, by their union, the superior alveolar arch. At the point where the posterioi border of the ascending process joins the frontal and the os unguis, is the particular spot for the application of the craniometer, oi dacryon. On the median line of the part subjacent to the anterior nares, are two other important points — the sub-nasal, which corre- sponds with the border of the nostril, occupied by an osseous point called the nasal spine, and the alveolar poiat, situated in the middle of the alveolar arch, at its anterior and inferior portion. The inferior maxillary bone is composed altogether diiferently — of a body, of a vertical and posterior ramus, which forms an angle with it, and of a border or alveolar arch. As a matter of detail, we may mention the coronoid process and the articular condyle, which terminate, the one in front of, the other behind, the superior border of the posterior ramus; then the mental emiaence, and behind it, internally, the tubercles g^ni. The thorax comprises, besides twelve dorsal vertebrae, which close it in behind, the sternum in front (Fig. 1) and twelve ribs on each side. Seven, called the true ribs, are directly connected with the sternum by cartilages; and five false are only united to it indirectly, the last two bearing the name of floating. The abdomen has no bone, ia the proper sense, belonging to it, but at certain points of its parietes are seen thick fibrous bands, which are the vestiges of ribs to be found in some mammalia, and especially in reptiles. The pelvic cavity, or pelvis (Pig. 10), is composed of bones which equally appertain to other parts, namely, to the vertebral column and the inferior extremities. Each extremity is composed (1) Of a base, which is the shoulder in the one and the haunch in the other. The bones which com- pose it form, by unituig with those of the opposite side, an osseous D 2 36 PHTSIOAl CHARACTERS. [Chap. i. cincture at each extremity of the truiii. At the superior extremity these are the clavicle and scapula ; and at the inferior, the iliac, or coxal bone, formed of three primordial bones — the pubis, the ischium, and the ilium. (2) Of a first segment, the arm, formed by the humerus ; and the thigh, by the femur. (3) Of a second segment, the forearm, formed by the radius and ulna; and the leg, by the tibia and fibula. (4) Of a third segment, the hand, made up of eight bones for the carpus, five for the metacarpus, and three for each finger, except the first, which has only two ; and the foot, made up of seven bones for the tarsus, five for the metatarsus, and three for each toe, except the first, which has only two. Of the bones of the tarsus, the calcaneum, or bone of the heel, merits particular notice. The femur, which we select as an example of a long bone, con- sists of (1) a shaft, or diaphysis, formed on its outer surface of a layer of compact tissue, and on its inner of a medullary canal ; and (2) of extremities, or epiphyses. At the upper extremity are the greater and lesser trochanter — processes for the insertion of muscles ; the neck, which is very long, and takes an oblique out- ward direction; and the articular head. The lower extremity consists of an internal and external condyle, and an articular surface. The humerus consists, in like manner, of a shaft, two tuberosities at the upper extremity, a very short neck, and a head ; inferiorly, of two processes — an external and an internal condyle. The bones, whether long, short, or flat, are covered by in- equalities, tubercles, eminences, or processes, all having the same object — namely, to furnish points of attachment for muscles and ligaments. It is to these several points we apply our instruments, as well as to certain edges and prominences, when making osteo- metrie measurements. We ought to mention also the styloid process, at the outer side of the lower extremity of the radius ; and the internal malleolus, on the inner side of the lower extremity of the tibia, &c. The flat bones of the cranium are united together by sutures, the long bones of the extremities by articulations. The most interesting of these latter, as far as we are concerned, is (1) The scapulo-humeral, in which the head of the humeru.s is received into the glenoid cavity of the scapula, a sort of ligamentous Chap, i.] PHYSICAL CHARACTERS. 37 bag, in wluch the two surfaces are kept in contact, and at the same time are permitted to glide easily the one upon the other. (2) The coxo-femoral articulation, in -which the head of the femur is received into the cotyloid cavity of the ihum. (3) The hinge-Kke articulations of the elbow and the ankle-joints, which only permit the movements of flexion and extension. (4) The superior articu- lation of the radius, so marvellously adapted for free rotation in every direction, &c. Bones, when first formed, consist of cartilage, the osseous matter being deposited at certain points, which afterwards coalesce. Later on, when the entire bone has become fuUy formed, and old age begins, those with sutures become soldered together edge to edge. Thus we have two orders of phenomena — ^the fusion of osseous pouits in one and the same bone, and the fusion of distinct and contiguous bones, which we must be careful not to confound, and upon which we shall have more to say presently. Variations of the Skeleton. The number of bones slightly varies in the mammalian series. All have seven cervical vertebrae, except the ai, or sloth, which has nine, and the lamantin, or sea-cow, eight. Among long-necked quadrupeds, as the giraffe, they only increase in height. The number of dorsal vertebrae, and of pairs of ribs which they support, is less constant — ^from eleven in the bat, they attain to nineteen or twenty in the elephant. The number of the lumbar vertebrae deviates but little, and varies generally from four to seven. The lamantin, however, has but one, while the dolphin has eighteen. These inconstancies do not, however, appear to have the importance which we might imagine. Genera far removed from one another have the same number of ribs or dorsal vertebrae : as the orang, the hare, the camel, the cat, and the kangaroo, which have twelve ; while contiguous species have a different number, as the ox of Europe, which has thirteen ; the aurochs, or wild ox, fourteen ; and the bison, fifteen — all three of the genus bos. Often the dififerenoe is merely that a lumbar vertebra becomes dorsal, or vice versa. When, in the human subject, there is a thirteenth rib on one side 38 PHTSICAL CHAEACTBES. [Chap. i. only, or thirteen on both, a lumbar vertebra is the point of articu- lation. The number of caudal or coccygean vertebrse varies in the monkey tribe — not including the anthropoid apes — from one to four in the magot to twenty-nine to thirty-one in the baboon and some of the ateles ; and among the rest of mammalia, from two in the Egyptian tapir to sixty ia the Cape rorqual. The bones of the head are constructed in. animals after the same model as in Man ; certain parts of them are more or less developed ; the cells or sinuses interposed between their laminae are more or less large ; some sutures, by closing slowly, leave certain portions of the bone isolated ; while others, owing to their becoming con- solidated early, diminish the number of bones. Hence the cause of the differences met with between them. Man, at his full develop- ment, has the smallest number of bones, and the rodents, at birth, the greatest number. Among the latter, the squamous portion of the occipital bone is divided into two, while the parietal and frontal are cemented together into one. The anterior and posterior sphenoids, united in Man, are distinct in the greater number of mammalia. The squamous and petrous portions of the temporal, on the contrary, remain distinct id, the latter, and perhaps, with one exception, are united in Man and the monkey tribe.* Moreover, we frequently observe in Man, as an anomaly, the reproduction of normal arrangements in other animals, as if by a sort of reversion towards certain states which its own organisa- tion might have gone through previously. Thus the fusion of the parietals into one — as among the rodents — the division of the frontal into two separate bones — common among mammalia — the persistence of an interparietal bone, &c. The early fusion of the two bones proper of the nose, especially in the inferior races, and the tardy consolidation, on the contrary, of the intermaxillary with the maxillary, are other examples of the same kind. Bones of the Nose. The bones of the nose proper remain separated on the median line up to an advanced age in the white ; their union is frequently * " Traite d'Anatomie Comparee," &o., by J. F. Meckel. Translated into French by Th. Schuster. Ten vols. 8vo. Paris, 1858. Chap. I.] PHYSICAL CHAEACTERS. 39 completed at twenty or twenty-five years in Hottentots. Of twenty- seven skeletons of adult men, taken at random by M. Broca, the fusion existed in five, all in negroes. In tlie cliimpanzee they appear united at two years of age ; in the gorilla and the pitheoians even sooner. But in the cebians their fusion is slow, so that these resemhle Man in this respect more than the anthropoids. Camper has forgotten the tardy union of the intermaxillary with the maxillary hones, and having made their constant absence to be distinctly characteristic of Man, we must speak of them more at length. The intermaxillary bones, to the number of two, appear to be united in the form of a wedge, enclosed between the two superior maxillary, supporting the incisor teeth, and having above two processes which partly close in the anterior opening of the nasal f ossEe. Though easily seen up to the third month, their independent existence is brief, they commence to consolidate at that period at their external side, and become united with the maxillary about the third year. I^Tevertheless their palatine sutures do not entirely disappear till towards twelve or fourteen years of age, according to M. Sappey, and were still visible in one hundred and four out of two hundred French skulls examined by M. Hamy. AH the phases of their solidification wordd be retarded in the negro races. InternuKdllary Bones. In the majority of mammalia the intermaxOlary bones continue, on the contrary, beyond adult age, and remain distinct. The elephant, the dolphin, and the sheep are an exception, and resemble Man in this respect; so do the anthropoids — their intermaxillary- suture should disappear about the end of the first dentition, accord- ing to M. Vogt. In descending the scale in monkeys, the inter- maxillary generally partakes of the characters which it has in the generality of quadrupeds. In the extremities the general type of Man and mammalia varies but little, and is unimportant. Some bones, for example, which, owing to the habits of the species, are superfluous, become atrophied, or anchylosed together. Thus the clavicles are reduced to mere 40 PHYSICAL OHABAOTBES. [Chap. i. vestiges ip. some carnivora, and disappear altogether in ruminants and amphibious mammalia. Sometimes one of the hones of the forearm or the leg becomes reduced in size, or anchylosed to the adjoiuing one. The same phenomenon is observed even more fre- quently at their extremities. The metatarsal or metacarpal bones are four in. number in the sloth, two in the stag, and one, called the cannon bone, in the horse. There is some relation between this number and that of the digits or toes. Thus the pig has only four digits, the rhinoceros three, the greater number of ruminants two, and the horse but one, called the hoof. In the horse the atrophy of other digits is manifest, the vestiges of them remaining; at the sides in the form of needle-like roughnesses. An analogous absence, as if from want of use, occurs in the bones; of the pelvis of amphibious mammalia, whose hinder extremities have become of little importance, or are wanting. The pelvis is- only represented by certain osseous styles which are amalgamated with the soft parts, or is altogether wanting. This is to be noticed in the dugong, the porpoise, the whale, &c. Relations of the Cranium to the Face. The cranium is formed of two portions in all mammalia — the- cranium proper, the receptacle of the brain; and the face, the receptacle of the principal organs of sense and of the masticatory apparatus. Their development is in an inverse ratio, and their respective situation in relation to that development. In Man the cranium is large and placed above the face ; in quadrupeds it be- comes less, and recedes more and more backwards ; in monkeys the- siae and situation of the cranium and face are intermedial. These two characters thus assume a considerable importance, and are the point de depart of other subordinate characters, which, in their turn, assist in distinguishing men and animals. It is natural, therefore, that anthropologists should early have bethought them of some decided methods of estimating their value. Various methods, have been proposed ; the one most in vogue is that of the facial angles. This was one of the first attempts of craniometry. This branch of anthropology, so cultivated at the present time, has been hitherto Chap, i.] PHYSICAL CHAEACTERS. 41 studied especially with reference to the comparison of races, and ■vviU consequently be treated at length in the second part of this work, which is specially set apart for that purpose. We will not now anticipate the subject further than by mentioning a few of the more striking characters which distinguish Man in general from animals. Facial Angles. The facial angles are four in number. The most ancient is the angle of Camper. It is formed by two Hnes, one called the hori- FiG. 4. — HH', Horizontal of Camper; FF', Facial line of Camper; FAH', Tme angle of Camper ; F B K, Angle of Greoffroy Saint-Hilaire and Cuvler, its vertex at the edge of the incisors ; 1 C M, Angle of Jules Cloqaet, its vertex at the alveolar border ; O D H', Angle of Jacquart, the sub-nasal point ; O D, Facial line of Jacquart. The most useful angle is that of Cloquet, with its vertex at C, but whose facial line, C I, impinges, not at the most projecting point of the forehead, but imme- •diately above the superciliary arches, zontal, H H', Fig. 4, which its author marked as a principal guide, over the auditory opening, and the inferior border of the nares ; the other, called the facial, F F', tangent to the two most pro- minent points of the face — the glabella, or central point of the forehead, above ; the surface anterior to the incisor teeth, below. 42 PHYSICAL CHAEACTEKS. [Chap. i. The original intention of Pierre Camper* -was to give to artists a method of comparing the heads of living persons with the skulls of different races and of different ages; hut in another -work he extended its use to animals Camper's Angle. Its apex was situated at the intersection of these two lines, at a point, A, Fig. 4, placed sometimes in front of the superior maxUlary, as in negroes ; sometimes hehind, as in many animals — the dog, for example ; or at the nasal spine, as in the white races. " The angle which the facial or characteristic line of the face makes," says Camper, "varies from 70 to 80 degrees in the human species. All above is resolved hy the rules of art, all helow bears resemblance to that of apes. If I make the facial line lean forward, I have an antique head ; if backward, the head of a negro. If I still more incline it, I have the head of an ape ; and if more stiU, that of a dog, and then that of an idiot." The second angle was suggested by Geoffroy Saint-Hilaire and Cuvier in 1795, and afterwards abandoned, no doubt owing to the difficulty of taking it with accuracy on certain animals. The facial line of Camper was maiutaiaed, but the horizontal line became oblique, K B, passing across from the auditory opening to the border of the incisors, B, where the apex of the triangle is situated. The third angle is a mean between the two preceding ones. The facial line rests tangent superiorly at the most prominent part of the face, but stops short below, on a level with the superior alveolar border, I G. The horizontal line descends obliquely, like that of Geoffroy Saint-Hilaire and Cuvier, but terminates at the same alveolar border, G, which becomes the apex of the triangle. Jules Cloquet adopted it in 1821. The fourth angle, which moreover has enjoyed very considerable repute, was the result of a misconception. M. Jacquart, in adopt- ing it in 1856, thought to follow m the footsteps of Camper, or • " Dissertation snr les Differences reelles qne presentenfc les Traits du Visage chez les Hommes de differents Pays et de dife&ents Iges," by- Pierre Camper.

Its apex therefore is always formed at the nasal spine, D. Our own measurements, made on more than eleven hundred human skulls, and on about a hundred skulls of animals, enable us to form a judgment as to the value of these four facia] angles.t JacqiiarPs Angle. The angle of Jacquart, at its apex at the nasal spine, varies Tinder five influences. (1) The degree of prominence of the nasal spine, very strongly marked, as M. Broca has observed, in the white races, often not observable in negroes; (2) The degree of prominence of the glabella, which, about one hundred and ninety- nine times out of two hundred, is the superior point of the facial Une ; (3) The difference of height of the auditory foramen rela- tively to the base of the skull; (4) The more or less marked elongation of the face, that is to say, the degree of prognathism ; (5) The amount of development forward of the anterior portion of the brain, as shown by calculations made among the hydrocephali, in whom the brain-case is very much enlarged, and among the microcephali, in whom it is very much diminished in size. Under aU these various influences, it is very diflScult to determine which has the greatest predominance, and consequently which represents the angle of Jacquart. The angle of Camper diminishes or increases for the same reasons, except that it has no reference to the prominence of the nasal spine. It takes account, however, of the elongation of the face in its sub-nasal portion, which has by far the most influence * "MensTiration de 1' Angle Facial et Gomom^tres," by H. Jacqnart, in "M^m.

[Chap, k on prognatliism in Man, and which the angle of Jacquart altogether leaves out of consideration. Angles of Qeoffroy and Guvier. The angle of Geoffroy Saint-Hilaire and Cuvier also sets aside the nasal spine, and takes in, in the same way, the sub-nasal region of the face ; but at the same time exhibiting it in a more complete manner. Hence we shall accord to it the preference. Why,, indeed, should we preserve the pretended horizontal line of Camper ? It does not exist in Man, and still less in animals. By intersecting with the facial line it more frequently has but one virtual apex, which gives an unfavourable impression. The auriculo-dental line of Saint- Hilaire and Cuvier is, on the contrary, rational ; it passes along at the same extremity of the face, and does not lose one of the two portions which one desires to measure- — the development of the face. Apart from these objections, which appertain to all the facial angles, the angle of Geoffroy Saint-Hilaire and Cuvier has- one specially belonging to it, namely, the impossibility of accepting; the Hne of the teeth as the extremity of the face. In a great many animals, in fact, the front teeth are either curved downwards, im- moderately elongated into offensive weapons, or are altogether wanting ; frequently, also, they fall out during hfe, or are lost after death. Gloquet's Angle. The angle of Jules Cloquet has all the advantages of the pre- ceding, without this latter objection ; we consider, therefore, that- it should have the preference. The principal objection which attaches to aU the facial angles is the adoption of, not the most logical point for the superior extremity of the facial line, but the most prominent, which is always found to be, with the angle of Jacquart, and almost always with the others, the glabella, or the centre of the superciliary ridges. The differences of prominence of these parts causes the facial angle in Man to vary several degrees ; that is to say, there is as much difference as there is between the natural faculties of races the most opposite. In animals it is even more so ; and Cuvier ■Chap, i.] PHYSICAL CHAEACTBES. 45 made up his mind, under all circumstances, to abide by the principle of Camper. What he very properly sought was the anterior limit of the brain at the lower part of the forehead — the yoint sus-orMtaire of M. Broca. In a gorilla, for example, by "taldng the most prominent point, which Kes over the superciliary arches, the facial angle, at its apex at the nasal spine, would be about 49 degrees ; whereas in reahty, that is to say at the supra- orbital point, it is only 37 degrees. Consequently it is always the anterior limit of the cranial cavity, whichever angle is preferred, and not the most prominent point, which should be taken for the facial line superiorly. It is in this way that the following angles have been measured, for the purpose of showing the difference between the most divergent human crania we have met with, an anthropoid and a carnivorous animal.

It has been argued, from the enormous angle in young anthropoids, that one must make the comparison in the child and not in the adult man, and then the distance is quite as great. The facial angle, then, furnishes a primary characteristic of Man in relation to animals. But it expresses less the relation of the size of the face to the size of the cranium, than the absolute development of the former. It attains seventy-two degrees in Man,, because the face is small and short, and only ten degrees in the wild boar, because it has considerable length and flatness. MetJiod of Guvier. Other methods lead to the same result. The most simple consists in estimating the importance of each part, and of com- Chap, i.] PHTSICAIi CHABACTEES. 47 paring tliem afterwards. Cuvier estimated, upon sections, that the cranium, in proportion to the face, was as follows : White man ... 1:1 Negro ... 4:1-25 Ctimpanzee ... 3:1 Gibbon, sapajou, and macaque ... 2:1 Hedgehog... ... 1:1 Porcupine ... 1:2 Hare ... 1:3 Horse ... 1:4 Whale ... 1:15 or 20 Method of Segond. M. Segond has proposed to measure, upon antero-posterior sections, the various angles formed at the level of the anterior border of the occipital foramen, by lines drawn from the principal points of the middle circumference of the head. On these sections he applies a graduated circle, whose centre corresponds to the basion (B, Fig. 6), and upon which needles, or movable radii, are directed towards the points desired. The face is thus found intercepted by- two lines, the one separating it from the cranial cavity, and which meets at the supra-orbital point ; the other going to the inferior border of the jaw ; the cranium being included between the same line of separation and the long axis of the occipital foramen. These two angles have given us the following results, which satisfactorily exhibit the relative development of the cranium and of the face : 2 European infants adults 3 adult negroes 1 chimpanzee 1 gorilla 4 orangs Otter Tisoaoha Dog ...

[Chap. i. Tery approximately ; tkat of M. Segond gives only one of the elements of comparison. It would be better to measure directly the base of the triangles, of which M. Segond only notices the angles, and to calculate their area ; or to obtain, on one side, the volume of the face by a sort of triangulation ; and on the other, of the cranium by the ordinary cubic measurement of its cavity. M. Assezat has commenced that part of the study which relates to the face in his " Edcherches sur les Proportions de la Face," communi- cated, ia 1874, to the French Association for the Advancement of Science ; it rests with him to extend it to animals. The question .as regards the cranium is not yet settled. Oapaeity of Cranial Cavity. The capacity of the cranial cavity is arrived at, as we shall see presently, by filling this cavity with grains of different sorts, and preferably with small shot, ia accordance with certain directions. The figures giving the height, volume, or weight of the human body, as compared with the volume of the braiu ia the mammalian : series, would form a very instructive table, if observers had taken more care to give us either one of these three elements. Our object, however, being to give more particularly the comparison of Man with ithe anthropoid apes, the following data wUl suffice : Cubic centimetres Man, European male, in round numbers ... ... 1500 16 gorillas, males 531 3 „ females ... 472 1 gorilla, 2nd dentition 440 1 „ 1st „ 413 3 oranga, males 439 1 orang, female 418 1 „ 2nd dentition 404 1 „ 1st „ 425 7 chimpanzees, males 421 3 „ females .. 404 1 chimpanzee, 1st dentition ■S28 2 lions ... .. 821 I bear ... .. 265 1 wild boar 207 1 ram ... 150 1 Newfoundland dog ... .. 105 Chap, i.] PHYSICAL CHAEACTBBS. 49 Thus we perceive tliat the capacity of the cranial cavity, and consequently the volume of the organ it encloses, increases slowly and gradually in animals, but suddenly and to a prodigious extent as we pass to Man. !N"ow all the animals except the last two or three are obviously of the same size as Man. If the three anthropoids are a little less in stature, their limbs, head, chest, and especially their abdomen, are much larger ; the gorilla, especially, is enormous, and ought, other things being equal, to have greater cranial capacity than man. The chimpanzee, however, has only 38'06 per cent.; the orang, 29'26; and the gorUla, 3540, as com- pared with Man, while the extreme proportions among gorilla males are from 31 "66 to 41 '53 per cent. Moreover, the diiFerence between the sexes is as iu Man : the cranial capacity of the anthropoid male exceeds that of the female by about 50 cubic centimetres. M. Vogt has tabidated a number of cubic measurements of the skuU, obtained by various methods other than our own, and amongst them that by the use of millet. They cannot be directly compared with ours, but their mutual relations merit consideration. Thus : Cubic centimetres. 1450 German skull, male 1 gorilla, male 2 gorillas, females 8 orangs, males 7 „ females 3 chimpanzees, males 1 chimpanzee, female 500 423 448 378 417 370 The conclusions deduced from these agree with preceding ones. By taking the mean, on the one hand, of all the anthropoid males of M. Vogt, and, on the other, that of all of ours, and comparing them with the corresponding mean in Man, we arrive at the follow- ing result : Mean absolute capacity of anthropoids.. Its proportion to that of man Vogt's 12 cases. Topiuard's 26 cases. 444 cub. cent. ... 490 cub. cent. 30-63 per cent. ... 32-66 pur cent. It is very evident from this that the three anthropoids in question have, cmteris paribus, three times less cranial cavity than Man. We do not hesitate to say that, taking into account the 60 PHYSICAL CHARACTERS. [Chap. i. bulk of the body, it is not three, but four and even five times less than is here stated. There seems to us to be a very fundamental distinction between Man and the animal most nearly resembling him. We have three or four times more brain — three or four times more thinking matter! The supremacy which our very exalted intellectual faculties secure to us, is confirmed to us by the existence of an exceptional development of the organ which is its seat. Anatomy furnishes us, at the outset, with powerful characters sufficient to satisfy the most jealous defenders of human preroga- tive, and to console them under the difiiculties they wHL meet with in matters of minor importance. We shall consider, shortly, the minimum and maximum variations observed in the capacity of the human cranium, and in the weight of its contents. But it may be useful to notice here these variations in the three great anthropoid apes. The three following series refer only to adults, and are the most significant that we have been able to bring together. In the first, the cubic measurement has been made by one and the same process — that of filling the skull with small shot ; in the two others the processes were different.* TOPINARD. 16 gorillas, males 3 „ females 3 orangs, males 7 chimpanzees, males ... 3 „ females VOGT, ETO.f 3 gorillas, females 8 orangs, males 7 „ females, and doubtful 3 chimpanzees, males ...

Bouvier, special preparator, for the loan of a number of specimens, for which we beg to express our obligations, " M^moire sur les Microcephales," by Charles Vogt. Genera, 1867. PHYSICAL CHARACTERS. 51 Chap, i.] The cranial characters in Man and animals, which we are about to examine, are partly the result of the difference of volume of their cranial cavity, and partly, and more especially, of the dififer- «nce of their natural posture. Man alone stands perfectly upright ; BV "Fig. 5. — K, Anterior border of the occipital foramen or baaion : C, Its posterior border, or opiathion : KG, Side view and plane of tbe occipital foramen; A, Alveolar point ; P, Inferior surface of an occipital condyle (articulating witb the first cervical vertebra, or atlas) ; A P Q, Horizontal plane of the base of the skull, or alveolo- condylean ; I, Inion ; L, Lambda ; B, Bregma ; O, Supia-orbital point, or ophryon ; G, Glabella ; N, Nasal point ; E, Sub-nasal point ; A, Alveolar point. the anthropoid apes have an oblique or side movement in pro- gression ; the other mammalia have a horizontal attitude ; hence their name — quadrupeds. Attitude of the Body The head, in all the mammalian series, is articulated with the vertebral column by means of the condyles of the occipital, which rotate from before backwards, and from behind forwards, in cavities formed in the bodies of the first cervical vertebra, or atlas. Between and behind these condyles is the occipital foramen, through which the spinal cord enters the skull ; its middle and anterior point is the basion, and its posterior point, the opisthion, of which we have already spoken. In quadrupeds, the occipital foramen and its ■condyles are situated very far backward, and in some, as the horse, they no longer occupy the base of the skull, whose posterior surface E 2 52 PHYSICAL CHABACTERS. [Chap, i- becomes vertical. The mazzh is at. the same time more or less elongated, as the zoological facial angle showed us just now. It foUows (1) That the head is no longer ia equilibrium upon the vertebral column, but falls forwards. (2) That its position has to be raised in order that the animal may see straight before him, the axis of the orbits being altered accordingly. In order to com- pensate for this excess of weight of the head ia front, and to- prevent its falling forwards, quadrupeds are furnished at the nape- of the neck with a very powerful ligament, called the posterior cervical, known in ruminants by the name of nerfde hceuf (paxwax). It runs along the spine, becomes free at the level of the seventh cervical vertebra, and is inserted into the external occipital pro- tuberance, or into a depression which replaces it. The powerful muscles of the neck contribute, with it, to preserve the head more- OT less in position. Conditions of Equilibrium of the Head. In Man, on the contrary, the head is naturally in equilibrium upon the vertebral column. The occipital foramen occupies the middle of the base of the skuU ; the weight of the portion in front of the basion, and that of the portion behind it, are sensibly equal, and the posterior cervical ligament is wanting, or is only represented by a simple aponeurotic interlacing. His position with regard to- seeing, on the other hand, is horizontal; the axis of the orbits is directed forwards, and the back of the retina is anatomically arranged in accordance with this. Special physiologists demon- strate in the same way that man's organisation is such that he sees better in the erect posture. Another result of the position of the head is a certain horizontality of the plane of mastication of the molars as well as the incisors, as may be shown by inserting between the teeth a flat rule, placed parallel to the horizon. Situation and Direction of Occipital Foramen. The occipital foramen is situated in the European at an equal distance between the anterior and posterior portion of the entire* Ohap. I.] PHYSICAL CHARACTEES. 53 cranium. In the negro, it is a little more backward; in tlie anthiopoid ape it is considerably so ; in tbe various quadrupeds it again recedes, and stUl more in tbe horse and the hippopotamus, in which it no longer forms part of the base of the skull Its plane looks downwards and forwards in the white man, directly down- wards in the negro, notably downwards and backwards in the anthropoid ape, and stOl more so in quadrupeds. The fundamental characteristics of the occipital foramen are its situation and direction. The portion of the occipital which is behind the foramen is very nearly horizontal, if not convex downwards, in Man ; whereas in animals it is more or less elevated from before backwards, and from below upwards. The foramen cannot there- fore be removed backwards, without its posterior border being elevated at the same time ; when stiU. farther back, this part of the occipital shell is transformed, as it were, into another posterior and altogether vertical wall of the skull, which is the boundary above of a strong horizontal crest, situated upon the superior semi- circular line. These successive modifications of posture are oblique as compared with . those of the biped, or, properly speaking, quadrupedal. The more the foramen is carried backwards, the more the equ.ilibrium is disturbed, and the more the weight of the anterior part increases to the detriment of the posterior. It wiU be sufficient to measure one of the two terms ; for ex- ample, the inclination of the plane of the occipital foramen ; that is to say, the angle which it makes with a given line being taken as a i;erm of comparison, to find the other, namely, the amount of dis- placement of the foramen. This is what was done by Daubenton, in 1764, by choosing the line D (see Pig. 6), passing from the posterior border of the occipital foramen to the inferior border of the orbit. The angle D A, looking forwards, thus determined was to 3 degrees in Man, 34 degrees in an orang-outang, 47 degrees in a macauco, about 80 degrees in the dog, and 90 de- grees in the horse. But Daubenton has never mentioned how he measured this angle; he appeared to be satisfied with a very ■doubtful approximation, to judge by his drawings. This measure- ment, the first attempt at craniometry, necessarily engaged the attention of M. Broca. By means of his occipital goniometer, he '54 PHYSICAL CHARACTERS. [Chap. I. at once demonstrated tliat the prolonged plane of the occipital foramen was elevated occasionally, in the white man, above the line adopted hy Daubenton, which gave an inverted or negative angle, which the latter had not foreseen. M. Broca was thus led to sub- stitute for the line of Daubenton another passing from the same point, the opisthion, to the root of the nose, and at a later period Fig. 6. — The anterior half represents the skull intact, in order to show the inferior border of the orbit ; the posterior half represents the skull open for the purpose of showing^ the occipital foramen and its two median points, anterior and posterior.

Ifow we have three angles relating to the occipital plane.

Between anthropoid apes and some others of the monkey tribe and the strictly mammalian quadrupeds, as the horse or the elephant, the deviation is still greater. The plane of the foramen is raised backwards to 90 degrees. Horizontality of Vision. Horizontality of vision ia the living subject, and of the axis of the orbit in the skeleton, depends more exclusively still on the upright posture. M. Broca, to whose labours we shall have so frequently to refer, is now prosecuting this subject. Alveolo-condylean Plane. Of aU the hnes, or planes, used iu craniometry, the most convenient, and, at the same time, the most physiological, is the alveolo-condy- lean plane, determined by three readily accessible points, viz. the alveolar, or middle point of the superior alveolar arch, and the most sloping poiats of the inferior surface of the occipital condyles. It is represented in Fig. 5 by the line A P Q, and ia Fig. 7 by the line C C. It is in relation to this alveolo-condylean plane, which is also called the natiiral plane of the base of the skuU, that M. Broca measures the degree of incliaation or of straight direction of vision, or, rather, of th« plane passiag through the two orbital axes. * We refer to the memoir of M. Broca, " Sur les Angles Occipitaux," " Eevne d'Anthropologie," vol. ii. p. 193, for the second decimals.

Biortital Angle. The divergence of vision furnishes another differential character i;o which M. Broca has given his attention, in his memoir " Sur le Plan Horizontal de la TSte," to which we refer the reader" for the figures. The second column above gives some of them, under the head of biorbital angle. It is the angle, open in front, which the two visual axes form between them, or, in other words, their degree of divergence. It varies from 40 degrees to 50 degrees in Man, and from 33 degrees to 62 degrees in the monkey tribe ; is raised to 73 degrees in the lemiu", increases enormously in quad- rupeds, and attains 143 degrees in the rabbit. This is how Man is commingled with the generahty of monkeys as far as the lemurs, and is separated from the mass of quadrupeds. The anthropoid apes, however, share his lot ; like him they have their orbital axes .a little divergent. Temporal Fossa. Of aU the mammalia, Man has the least development of the muscles of the jaw, and the smallest extent of surface for insertion •of these muscles. What a difference between his small temporal fossa, bounded above by a curved hne, which is at times clearly marked, and the deep fossa of the anthropoid apes ! ISoi only does the whole of the lateral surface of the skull in these latter give insertion to the fibres of the temporal — the masticatory muscle par excellence — ^but also on the median line in the male there is besides a large elevated crest, which allows of these fibres being increased to any extent. The elevation, too, of the temporal line, the extent of its curve, and its nearness to the median line, are, in the human group, marks of inferiority. In certain prehistoric skulls from Florida, and modem ones from ISew Caledonia, the two lines. 58 PHYSICAL CHAEAOTERS. [Chap, u distant normally from 8 to 10 centimetres, do not deviate but about 3 to 4 centimetres, thus showing a marked resemblance to the female anthropoids. The condyles of the inferior maxillary, and the glenoid cavities- in which they are received, are directed transversely in the carnivorous mammalia, from before backwards in rodentia, and are flat in the herbivora. In Man they have an intermediate direction, thus bearing testimony to his omnivorous functions. Teeth. ' The teeth, divided into incisors for cutting, canines for tearing,, and molars for grinding and triturating, show still more clearly this aptitude of Man. Of his immediate zoological neighbours, the orang and the chimpanzee resemble him the most iu this respect,, particularly in their molars ; the gorilla, on the contrary, differs from him, and in the arrangement of his teeth somewhat resembles, the carnivora. The canines are larger in the anthropoid apes, and have a length and size which entitle them to be regarded as offensive weapons,, particularly in the goriUa. Between the canines and the upper lateral incisors may be noticed, among adult anthropoid apes, as ia the greater number of the monkeys next in order, a gap, called diastema. This is, in great part, for the reception of the inferior canine, while the superior canine presses between the inferior canine and the first premolar, and so wears itseH a place mechani- cally. Another characteristic of the teeth of anthropoid apes is the projection of the anterior incisors, which is more exaggerated than in the lowest races of the human group. Man, at least the white, has vertical teeth ; the canines, as weU. as the molars and incisors, are close together and smaller. His small permanent molars have two tubercles, and the larger four ; in this respect there is no difference between him and the anthropoids. There are twenty temporary and thirty-two permanent teeth, exactly as in the four anthropoid apes, the pithecians, and the greater number of the lemurs. In the cebians, a small molar is added on each side, which raises their total number to thicty-six. Some Chap, i.] PHYSICAL CHABACTBRS. 59. monkeys have a different dental formula ; the macauco, for example, has thirty-eight. The progress of the eruption of the teeth in monkeys, and their periods of succession, are but imperfectly known. It is certain that the eruption is more rapid (cceteris paribus) in the anthropoid apes than in Man.* The superior alveolar arch in Man is generally in the form of an hyperbola with relatively short branches ; that of the three Fig. 8.— a, Jaw of the European ; B, Jaw of the Chimpanzee. principal anthropoid apes takes the form of a U with long and exactly parallel branches; that of the sajou and the macaque is eUiptical. — {Broca). Other characters have been given as peculiar- to Man ; for example : * See " L'Homme et les Singes Anthropomorphes," by M. Magitot, in " Bull. Soc. d'Anthrop.," 2nd series, vol. iv. p. 113.

But this character has lost its value since its ahsence has been noticed in a certain number of human specimens, among them the prehistoric jaw of the N'aulette, and some contemporaneous ones represented by MM. Quatrefages and Hamy. The existence of the tubercles g^ni, on the posterior surface of the inferior maxillary bone, which are replaced by a depression in monkeys. But exceptions of an opposite kind are met with con- tinually, such as tubercles in the anthropoid apes, the depression on the jaw of the Naulette, &c. The presence of a nasal spine. But some monkeys have one, -whilst in many negroes it is so slight as to be almost invisible. Different Cranial Characters. The articulation of the greater wing of the sphenoid directly with the parietal. — {Owen). But in a great many specimens of ■different races, especially the inferior ones, a bridge formed by the union of the temporal and frontal is interposed between the two preceding bones. M. Broca describes the first of these arrange- ments as usual in Man, under the name of pterion en H (see D, Fig. 2), and the second as usual in monkeys, under the names of pterion retourne, when the temporal and sphenoid are largely united, and of pterion en K when they only touch each other. The size of the mastoid processes. This is a result of the •development of the sterno-mastoid muscles which are attached to them, and have relation to the biped posture. There is no new cranial or facial character, however strongly marked, which can be drawn as a line of demarcation between Man and animals, but numerous cases wiU arise to efface or to weaken it. In the head, the transition to the anthropoid apes would be inappreciable, but for the five following characters of Man: (1) The increase of volume of his cranial cavity; (2) The rela^ tively inverse diminution of the face; (3) The increase of the facial angle which arises from it; (4) The situation of the occipital ioramen below, and at the centre of the base of the skull, and the Chap, ii.] TERTBBEAL COLUMN. 61 horizontality of the two orbital axes, both dependent on the biped posture. But the first is of such pre-eminent importance that we would sum up by saying : The head of Man is only distinguishable from the head of animals by a single important character — the capacity of the brain-case.

The cervical region, which is in continuation with the head, does not materially differ in the mammalian series, except in the height of the vertebrae as before stated. M. Broca has, however, described certain variations in it. The spinous processes, bifurcated in Man, are simple in the anthropoid apes and in monkeys ; but in some human skeletons of an inferior race they have been found simple ; and in the chimpanzee two of them are bifurcated, which establishes, a transitional link between them. In the second place, the anthro- poid apes and Man have the superior surface of each vertebra bounded by two projections, which are wanting in the inferior monkeys, whilst they have no little appendix with transverse processes, as in the lemurs and camivora. Their types, in con- sequence, have been disarranged by being separated from that of" the next zoological groups. Conditions of the Equililrium of the Trunk. The differences which the dorso-lumbar region presents are very characteristic. Normally composed in Man of twelve dorsal vertebrae and of five lumbar, it has sometimes thirteen dorsal and only four Imnbar, as in the gorilla and chimpanzee. There is not. <62 EQUILIBRIUM OF THE TEUNK. [Chap. li. therefore, any very serious difference in this respect hetween these two and ourselves. The orang, on the contrary, loses one lumbar vertebra, and the gibbon gains one dorsal, which brings up the "total number of dorso-lumbars to sixteen in the one and eighteen in the other. In the pithecians generally, and in most of the «ebians, there are nineteen, there beiag more lumbar in the former and more dorsal iu the latter. In lemurs there is an iacrease in both regions, but especially in the lumbar. The slender loris has ■altogether twenty-three or twenty-four dorso-lumbar vertebrae. The dorso-lumbar region presents other differences much more important, which have relation to the three kinds of posture or ■attitude of niammalia — the vertical, the oblique, and the horizontal. ■ The human head is in natural equilibrium on the spiae — weU and good ; but the weight of the viscera contained ia the thoracic and abdominal cavities tends to throw the whole trunk forward. To counteract this, two anatomical arrangements come in. Elastic ligaments, called yellow, are interposed between the vertebral laminse, and, by virtue of their structure, keep the body erect without fatigue. A number of ligaments and inuscles, almost always more or less fixed at a right angle — that is to say, under the most favourable incidences, at the extremity of the spinous .and transverse processes throughout the entire length of the column — conduce to the same end. In the second place, the vertebral column presents three alternative curvatures, which tend to preserve the line of gravity of the head and trunk in the axis of sustentation passing through the pelvis. By the first of these curvatures, the cervical, whose convexity looks forwards, the weight of the head is brought backwards ; the second, or dorsal, being directed the reverse way, brings the centre of gravity forwards ; while the third, or lumbar, with an anterior convexity, serves the purpose of keeping the whole column erect. In quadrupeds, on the contrary, there are only two curvatures, the one cervical, as in Man, the other dorso-lumbar, with the con- vexity looking backwards, like the dorsal region in Man — or rather looking upwards.* It foUows that, if by any contrivance one * It is weU to remark that in the vertical posture of Man, the posterior part of the oolulnn, and of the whole trunk, looks backwards, and the Chap, ii.] CURYATtTEBS OF THE VERTEBEAL COLUMN. 63 compelled tlie individual to stand upright, the line of gravity ■would be forcibly brought forwards, and the weight of the viscera would come to lean against the anterior wall of the thorax, or the inferior wall of the abdomen. Curvatures of the Vertebral Column. Monkeys, in this respect, are divided into two groups : the pithecians, the cebians, and the lemurs, ■which have the dorso- lumbar curvature only, conformably with their quadrupedal attitude ; and the anthropoids, which appear under various aspects, more approaching, however, the human arrangement. Many gibbons have three very marked curvatures. In the chimpanzee, the lumbar •curvature, distinctive of the human group, is only over the last two vertebrae, and in the orang, over the last. The gorilla, with his straight lumbar column, is farthest removed from Man, without, Jiowever, presenting the absolute organisation of the quadruped. The division of the trunk and of the vertebral column in Tuammalia in general into two series — the one anterior, the other posterior — and the absence of all distinction of this kind in Man, is more characteristic. Let us explain this, according to the views of M. Broca. A muscle is a fleshy mass, elongated, and more or less attached at its two extremities, which approach each other when the muscle contracts imder the influence of the vnll. The more movable extremity is displaced, drawing along vnth it the lever to which it is attached, whilst the other, rendered immovable by other muscles, remains stationary. In any movement, then, we must ■consider the action of a whole system of muscles, and not of one -only. In Man, the muscles which indirectly contribute to locomotion, anterior part forwards ; whilst in the horizontal poStTire of quadrupeds, the former looks upwards and the latter downwards. In the same way the upper extremities of Man become anterior in quadrupeds, and the lower posterior. The anthropoid apes passing continually from one posture to the other, both orders of arrangement can be applied to them. "L'Ordre des Primates: ParaUfele Anatomique de I'Homme et des ■Singes," by M.

[Chap. ii. by fixing the pelvis and the successive portions of the vertebral column which furnish the point d'appui, are attached to the spinous and transverse processes of the vertebra, and tend through- out their whole length to draw or bend them downwards in a direct ratio to the limited mobility of the whole column. The dorsal processes yield considerably, are bent down and imbricated ; those of the lumbar yield less. In quadrupeds the traction of the process is exerted, on the contrary, in the direction of the anterior extremity in the lumbar vertebrae, and of the posterior in the dorsal. These processes are inclined, then, in a contrary direction — the lumbar upwards and the dorsal downwards. The spot where the change of direction takes place establishes the division between the anterior and the posterior series. It is situated in the carnaria, between the last dorsal vertebra but one — which is attached to the thorax by a costal oartUage — and the last, which only supports one of the fl.oating ribs. The spiuous process of the one is inclined upwards, that of the other downwards, and it is there that the two series becom& independent. Anteversion and Retroversion. Thus, by the appearance alone of a vertebral column, we recognise- the habitual attitude of the individual. In Man, the processes are aU oblique below, or in retroversion ; he has but one series. In quadrupeds, the dorsal processes are descending, except the last, and the lumbars ascending, or in anteversion ; they have two series. All the monkeys proper are in the latter category, generally in a very marked way in lemurs, less in cebians, less still in the higher species — the pithecians. " The scene suddenly changes as regards the anthropoid apes. All the characters indicating the func- tional separation of the series in front, and of that behind, have completely disappeared. The dorsal spinous processes, by their length, their great obliquity, and their imbrication, approximate to the human type much more than to that of the pithecians and other apus ; those of the false dorsal are obliquely inclined towards the Chap, ii.] STYLOID PROCESSES OF THE VERTEBRA.

In the semnopithecus (Kg. 9), belonging to the family of pithecians, are represented the single dorso-lumbar CTirvatm'e, with its convexity looking upwards ; the retroversion of the spinous processes of the dorsal vertebrae (except the last two), the ante- version of the lumbars, and the scarcely visible processes of the Fie. 9.— Skeleton of Semnopithecua Entellus, one ol the Pithecians. last two dorsal, answering to the separation of the trunk into two series — ^the one anterior, the other posterior.

[Chap. ii. rib being excluded from it. A special system of processes, called styloid, detached from tbe lumbar vertebrae, and which does not exist in Man, nor ia the anthropoid apes, has the same design in the posterior series. Sacrum and Coccyx. The mode of termination of the vertebral column — ^below in bipeds, behind in quadrupeds — ^has been the object of careful study by M. Broca. According to him, the vertebrae -which are articulated with the coccyx form the true sacrum, while all the remainder appertain to the tail, which is divided into two segments ; the one basic, formed of true caudal vertebrae, in which the spinal canal remains ; the other terminal, formed of false caudal vertebrae — that is to say, with their bodies reduced in size. All the inferior monkeys, with but few exceptions, have a sacrum of three vertebrae, all articulating at the sides with the ilium — that is to say, true sacral vertebrae. The tail, which forms the termi- nation, is composed of five true and twelve false caudal vertebrae in the macaque ; of seven true and twenty-two or more false in the ateles paniscus ; of five to seven true, and twenty-four to twenty-six false, in the cynocephali generally; of five true and four false in the lori, &c. In the so-caUed tailless moiikeys, the sacrum is formed, as in those above mentioned, of three anchylosed vertebrae ; but the remainder is either reduced in size in each of its two kinds of vertebrae — as in the cynocephalus niger, which is reduced to three true and three false caudals ; or more or less atrophied from the extremity to the base, as in the magot, which has no trace of false caudals, and has from one to four true. In Man the type is altogether different. His sacrum is composed of two parts, the one consisting of three vertebrae, as in the monkeys mentioned above, which articulate with the ilium and constitute the sacrum nScessaire ; the other of two or three vertebrae, free at their external borders and having a spinal groove, and which represent a sacrum suppUmentaire, anchylosed with the former. The coccyx consists of four or five vertebrce — all false. Man, then, has a tail Chap, ii.] PELVIS. 67 formed of six or eight pieces, the fiist being at the hasic segment and the last at the terminal segment, as in Tn a.TnTin a.1ia. generally. The justice of this interpretation is confirmed by studying the extremity of the vertebral column in the foetus. To what type do the anthropoid apes approximate t "In aU, the true caudal Tertebrae are anchylosed mth the sacrum, as ia Man, and the coccyx is composed of false vertebrae only, similar to those of the coccyx of Man — that is to say, more developed in ■width than in height, and flattened from before backwards." — (Broea). The supplementary sacrum of Man is formed, four times out of six, of three vertebrae, instead of two ; and that of the anthropoid ape varies from two to four. Ought we to look upon this as a difference ? Other morphological variations in the coccyx, of less importance, equally present themselves in both. In a word, Man and the higher apes resemble each other iu the conformation of the taU, at the same time that they differ in this respect from monkeys proper. TJie Pelvis. The pelvis exhibits considerable differences between Man and quadrupeds, which arise from their different attitude. It is fornied of two halves which originally consisted of three distinct bones — ^the Uiimi, the ischium, and the pubis, at the junction of which, externally, is the cotyloid cavity (c, Fig. 10). It is divided by a circular crest, called the superior brim, into two portions, termed the greater and lesser pelvis. The fcetus lies, and is matured, in the former, and passes into the latter a short time previous to birth. In Man, the Uiac bones are expanded, laterally, into two great wings, thin in the centre, and concave — admirably constructed to support the mass of the viscera, and in the female the weight of the foetus. Their external surface, or external iliac fossa, is, in consequence, convex, to give insertion to the muscles of the buttock. In quadrupeds, on the contrary, the Oiac bones are closer together, are elongated on each side of the lumbar portion of the column, and p 2 68 EELYIS. [Chap. ii. convex on their internal surface, the external becoming inversely concave. The iliac bones in Man therefore have somewhat the form of valves, which are composed of flat bones. They rapidly become long and tapering, on the contrary, in quadrupeds, as in the equidse, the hare, and the kangaroo, and are converted, as it were, into long bones. Between these two arrangements are seen all kinds of intermediary ones.

It is the reverse ia Man — the hreadth is as 28-77 per cent, to the length. The anthropoids vary, but they come nearer to Man than to quadrupeds. The gihhons, like the other monkeys, have stUl the length greater than the breadth. In chimpanzees, the two are nearly equal. The gorillas and orangs are very nearly allied to Man. The breadth exceeds the length in 24 per cent, in the former, and in 16 -50 in the latter. For certain physiological reasons peculiar to their group, the elephants and the mastodons have the pelvis of similar conformation to that of Man. Consequently the sacrum of quadrupeds is straight, elongated, a little hoUow on its internal surface, and is iu contrast with that of Man, which is wide at the base, thick, conical, and curved at the point. The sacrum of anthropoid apes holds a middle position, and frequently resembles that of some of the inferior races of Man, as the Hottentot, dissected by Jeffries Wyman, or the Bosjes woman, by Cuvier. At the same time that the human pelvis becomes wider and diminishes in height, its antero-posterior diameter becomes shortened, relatively to that of the anthropoid ape and other mammalia. The promontory — ^that is to say, the projecting angle in front which the curve of the loins makes with the curve of the sacrum, is, on the other hand, stronger, in accordance with the requirements of the biped attitude. We may add that the tuberosities of the ischium are shorter, less widely separated, and less marked than in the anthropoid, and that the symphysis pubis is shorter. That which we remark in the pelvis may also be found at the other extremity of the trunk. Tlie TJiorax. The thorax, in Man, is more developed transversely; that of quadrupeds, on the contrary, is more so from before backwards, or from the sternum to the spine. The arms in the former have to move in aU directions, and especially outwardly, and to this end 70 STERNUM. [Chap. u. are kept wide apart by the arches, which are the clavicles. In the quadrupeds proper, they only serve for locomotion, fall in a parallel way downwards, and remain apart. Thus the clavicle disappears, and the thorax becomes flattened sideways. Monkeys, in this respect, hold an inferior position to quadrupeds, a superior one to Man. The lemurians, the cebians, and the pithecians have the thorax compressed laterally, the anthropoid apes rather from before backwards. The volume of the chest could not furnish any special character. Its development is enormous in the three great anthropoid apes.

The Sternum. The sternum in the same way, while broad and flat in Man, is narrow and developed antero-posteriorly, or rather from below up- wards, in quadrupeds. In this respect the anthropoid apes come nearer to Man. The sternum is composed, speaking philosophically, of seven portions, corresponding to the seven ribs which are directly articu- lated with it, and of a xiphoid appendix. These are distinctly seen in the foetus, but at bu-th are reduced to two — exclusive of the Chap. ii.J THE HAND AND FOOT. 71 appendix — namely, the handle and the body, the latter being formed by the anchylosis of the six lower portions. The handle, or upper separated portion, exists in all the mammaha with clavicles ; the appendix also. The body is entire in Man; in the greater number of the monkeys proper it is composed of six distinct parts ; in one of the anthropoids, the gibbon, it is entire, as ia Man, and in the other three it is divided into three or four. Thus we see that in this respect the anthropoid apes, and notably the magot, are between Man and the pithecians. The extremities, four in number in the majority of mammaha, are reduced to two, the anterior, in the whale and the porpoise. Their terminal segment bears the name of foot or hand, a denomina- tion upon which Blumenbach and Cuvier based their division of the order of Primates of Linnseus into Bimana, comprehending Man, and Quadrumana, embracing the monkey tribe, a name which Tyson had given them in 1699. The Hand and Foot. What then as to the hand and foot, and especially the hand'? Cuvier says that which constitutes the hand is the faculty of opposing the thumb to the other fingers for the purpose of taking hold of the smallest objects. Agassis terms the hand, " a hmb having a certain number of fingers bending one way, another finger being opposed to them." He defines a foot as, " a limb terminated by digits aU on the same level, and all having the same direction." The hand is recognised, according to Huxley, by the disposition of the bones of the carpus and of the metacarpus ; the foot by the presence of short flexor muscles, a short extensor of the digital appendices, and a long peroneal All these definitions look only to one side of the question. M. de La Palisse's maxim is that it is their use which distinguishes the foot from the hand. Tlie Foot. M. Broca, with greater breadth of view, says : " A foot is an extremity which serves chiefly for standing or walking ; a hand is 72 THE FOOT. [Chap. n. an extremity -vvliicli serves principally for prehension and touch." We might add that the fin is an extremity which serves principally for natation, &o. The hand is perfect when it answers the end for which it was exclusively intended. The foot is perfect when it is only constructed for waLking. Both are imperfect when they encroach on the functions which do not specially belong to them. An anterior extremity may lose all its functions of prehension, and it would be only a foot. Various physiological variations, and of different degrees, are noticed in the mammalian series. But if the sole of the foot bears directly on the ground, or if the palm of the hand grasps objects, the whole extremity is, in reality, applied to its general function, all its parts are made conformable to the purposes for which it was designed. It is not, then, the foot or the hand only, but the extremity as a whole, which we must examine to discover its function of prehension or locomotion. This has been already done by M. Broca. The anatomical conditions, which secure to the inferior extremity its function of locomotion, "may be reduced," says M. Broca, "to three: (1) The root of the extremity — that is to say, the head of the femur,* should be received iuto a deep hemispherical cavity, looking downwards and outwards, which allows the limb to move freely from before backwards, and' from behind forwards, to execute the two movements of progression, whilst the other move- ments, and, in particular, adduction, are very limited ; (2) The two bones of the leg shotdd be immovable the one on the other, and more or less united together as a single bone, in order to bear the weight of the body, and so that the foot may not turn ; (3) The articula- tions immediately above the part touching the ground should only allow two movements — those of flexion and extension — and should be bent at a more or less right angle, in order to present to the ground a flat surface, formed at the expense of the posterior surface of the extremity, now become inferior." Man, who exclusively rests on his two feet, realises all these conditions in the highest degree. His femur, retained in the * We refer the reader to page 30 and following for the anatomical expres- siona employed here, and elsewhere, with respect to the skeleton.

In the majority of mammalia, these arrangements are identical, 74 THE HAND. [Chap. ii. or analogous. Whether tlie constituent columns of the foot amount to four, three, or two; whether the individual hears on his phalanges, his metatarsus, or the entire sole of the foot, they are always adapted for waUiLng and for support. The cheiroptera, which make use of their foot as a hook, and perhaps kangaroos, which are able to grasp in a slight degree, are the only animals having free movement of the two bones of the leg one upon the other. We shall speak of the monkey tribe presently. The Hand. The indispensable qualities for the regular performance of acts of prehension and touch, of which the upper extremity of Man offers the best example, are also three in number. (1) The articulation of the humerus with the scapula, or scapulo- humeral, should be movable in two directions, in order to allow the arm and hand play in every direction. Circumduction and adduction, if hmited in the femur, are not neglected here. The presence of the clavicle, by widening the shoulders, favours the latter ; the glenoid cavity is small, ovoid, and looks outwards ; the axis of the humeral head lies perpendicularly. These last two features are sufficient of themselves, in doubtful cases, to enable one to recognise the character of the upper extremities. We are now about to show this. The arm is a thigh turned round, says Professor Ch. Martias.* The articular liue of the knee and that of the elbow are both transverse, but while the flexion of the knee takes place backwards, that of the elbow is forwards ; the patella and olecranon, which are analogues, occupy inverse positions. In reptiles the two extremities are, on the contrary, symmetrical ; and, as M. Durand (de Gros) says, isomerous, flexion being exerted in the same direc- tion. How is this difference in mammalia to be explained ? In a very simple way. The part of the arm which is above the middle third has undergone, in the former, a twisting from behind for- * "Nouvelle Comparaison des Membres Pelviens et Thoraciques," by Ch. Martins, in " Mem. Acad, de Montpellier," 1857. Chap, ii.] THE HAND. 75 wards, and from within outwards, as if the honehad been tumedround. Proofs of this are visible upon the humerus ia the shape of a groove of torsion. This is why the thumb, which is inwards in the foot, has become outwards in the hand. But this twisting or rotation, has not the same extent in bipeds and quadrupeds, or rather in. the humeri of the limbs, whether designed for prehension or for locomotion. Fig. 13. — Skeleton of the forearm : A, In supination ; B, In pronation ; R, Radius ; U, Ulna. H, Humerus ; In the. former case it is about 180 degrees, in the latter about 90 degrees. Moreover, in bipeds, as in quadrupeds, the forearm is bent upon the arm in a similar way relatively to the body. It is because the glenoid cavity of the scapula describes, in the latter, a complementary are of a circle, equally from behind forwards and from without inwards, that so much of it is spared for the humerus ; consequently it looks forwards relatively to the axis of the body in these, and downwards in quadrupeds. The 90 degrees for the humerus and the 90 for the glenoid cavity, thus 76 THE HAND AND FOOT. [Chap. ii. give the 180 degrees which make of the arm a " thigh turned round." The degree of rotation varies sometimes in both, and the part which the humerus takes in it is measured hy the angle which the vertical plane of its head makes with the vertical and transverse plane of its inferior extremity. Thus an angle of torsion of the humerus of 180 degrees, and a glenoid cavity looking outwards, are the characters which the scapulo-humeral articulation exhibits in the extremities destined principally for prehension. A similar angle of 90 degrees, and a glenoid cavity looking downwards,* are, on the contrary, the characteristic of the function of locomotion. If the cavity, in this case, had looked outwards, the head of the humerus, instead of resting upon it, would he driven back against the articular capsule, which by the least shock would be ruptured. (2) The radius should turn freely over the ulna, so that the hand, placed in pronation at its extremity, can be put in supination and lay hold of objects readily. Fig. 13 shows the difference between these two positions of the arm. This rotation in Man is about 180 degrees. (3) The hand should be situated upon the prolonged axis of the forearm, the carpus being articulated with the radius in such a way as to have every kind of movement, and especially the most com- plete flexion and extension. Everything which adds to the mobility of the phalanges, and facilitates especially the opposition of the thumb to the other fingers, is favourable to tliis end. Thus mobility of the member in all its parts is that which characterises the hand, solidity that which marks the foot. The details of configuration is only a question of relative perfection in either case. Hand and Foot. The anterior extremities of Man exhibit all the attributes above mentioned, which go to make up a perfect organ of prehension. Those of the carnivora and paohydermata differ from them entirely, * Downwards, because we are thmking of qnadrupeds ; but if we suppose the trunk vertical, it is forwards. Chap, ii.] THE HAND AND FOOT. 77 and are adapted in all their parts for locomotion. We find all terrestrial mammalia incliaing towards one or other of these two types. In the kangaroo, the movement of pronation and supina- tion, the axis of his hand being in continuation with that of the forearm, the conformation of his five digits, everything, except that the glenoid cavity looks forward,* goes to show that his anterior extremity is formed for prehension. In the dog, the anterior extremity, on the contrary, is better adapted for progression, and, therefore, the two bones of his forearm move one upon the other. It is scarcely necessary to enumerate the many rodentia, carnivora, and edentata which employ their front paws as hands to seize their prey, to carry it to the mouth, to burrow ia the ground, to caress their young, to carry them, &c. In the common monkeys the anterior extremities hang loosely at the sides of the body ; their angle ' of humeral torsion is that of quadrupeds. In the lemurs, the ouistiti, the atele, and the sapajou it is as high as 95 or 100 degrees; in the magot, 105 degrees; in the semnopithecus, 110 degrees. The amount of rota- tion of the radius is variable ; in some cebians and pithecians it does not exceed 90 degrees ; iu the mone it attains to 100 degrees. When the common monkeys use the hand as a foot, it is held at an angle more or less approaching a right angle, and leans on the ground by the whole palmar surface, with the digits extended ; it has then all the character of a foot. But if they use it for seizing objects, or the limb is left to itself, as in the dead body, the axis of the hand is continued in a straight Hne with that of the forearm. It is, then, to aU intents and purposes, a hand. With regard to their posterior extremity, it possesses aU the characters which render it adapted for locomotion ; its terminal extremity is set at a right angle, and rests on the ground by the whole plantar surface. Tlie digits are nevertheless longer, and the thumb more loosely attached and more spreading, than in. Man ; the thumb is not opposed to the other digits, as we have said, but by its span it plays the part of one leg of a cramp-iron or pincers, * We say forwards because the kangaroo holds himself most frequently in the standing position. 78 THE HAND AND FOOT. [Chap. ii. the four other digits forming the other leg. It is by this means that monkeys hang on to the houghs of trees as well by their feet as hy their hands. In a word, the common monkeys have feet behind and hands in front, but they employ them subordinately, the former for climbing and the latter for walking. Properly speaking they neither belong to quadrupeds nor to the quadru- mana. In anthropoid apes all the characters proper to the organ of prehension are developed in the same degree as in Man : there is the same independence of the limb — greater in the gibbon perhaps ; the humeral angle of torsion is about 150 degrees, whilst that of the negro is 154 degrees, and that of the white man 168 degrees, according to M. Gegenbaur; the movement of pronation and of supination of the radius is from 140 to 180 degrees, whilst that of Man is 180 degrees ; the axis of the hand is in continuation of that of the forearm ; the power of extension, that is to say, the move- ment which would, when required, make it serve for a foot, is less than in Man; the configuration of the bones of the hand is identical with that of Man, except that the orang and some gibbons have an additional bone in the carpus, called the intermedium, and that the thumb has greater span in the gorUla, and is some- what atrophied in the orang, and perhaps in the chimpanzee. As to the inferior extremity, the resemblance to that of Man is stiU more close, except that the orang has the great toe much smaller, and much more behind. In fine, the gorilla most nearly approaches to Man in the shape of his hand and foot, while the chimpanzee comes next. The anthropoid ape seizes the smallest objects with the thumb and fingers of his hand, which he opposes perfectly. In the foot the opposition is nil — it is not greater than that of Chinese oarsmen, Nubian horsemen, or painters without arms, who lay hold by bending the toes all together, or by making the second toe act as a thumb. His thumb and digits can only clasp the two sides of a bough, like the two legs of a cramp-iron, in the act of climbing. His ordinary method of progression is in an oblique direction, the legs close together, the arms extended and somewhat separated Chap, ii.] THE HAND AND TOOT. 79 when making a step; the forearms in pronation, and the hands closed, resting altogether upon the inner border and the dorsal surface of the phalanges. The orangs which we have had an opportunity of seeing, walked with the toes turned under, and with the external border of the foot resting on the ground. It seems, nevertheless, that other anthropoids sometimes rest on the entire iiat surface of the sole of the foot, and that they keep the toes extended. With regard to the erect position, the anthropoid ape assumes it frequently, but only by accident. Thus we have seen gibbons run along in the upright position, the arms elevated above the head, and thrown backwards, evidently in order to place their centre of gravity in a more favourable position. The gorilla generally runs away from Man, but if he suddenly finds himself in. his presence, or has to cover the retreat of the female, he faces his enemy with the greatest bravery, holds up his head, strikes his chest, and comes forward in an upright position with the head erect. The chimpanzee frequently straightens himself in the same manner. The orang is so apathetic that he almost always walks along crawKng. In a word, the anthropoid ape is a biped, but he possesses an arrangement of the feet which allows him to walk upon the branches of trees. He is bimanous, but he has the assistance of his hands in walking, as we ourselves should have if, with longer arms, we wished to imitate him. His attitude in progression is more nearly the vertical than the horizontal, and is sometimes that of Man and sometimes that of quadrupeds. To return to terrestrial mammaha. Their posterior extremities are always adapted for progression, the anterior sometimes for pre- hension, sometimes for progression, frequently for both. The four extremities should, in the main, be simply for support. The more or less perfect adaptation of the anterior to the act of touch and prehension is a characteristic of gradual development, and if one must establish a graduated scale in reference to this matter, the series would succeed each other as follows ; the pachydermata and ruminantia, camivora in general, kangaroos, ordinary monkeys, anthropoid apes, Man. 80 STATURE. [Chap. ii. Stature. Having considered the skeleton in detail, it remains for us to examine it in its ensemble. Height and size in comparative . anatomy have a secondary value, the largest animals go side by side with the smallest in contiguous genera. Among the gibbons, for example, the siamang reaches 1'16 mfetre; the entelloid, 80 centimetres. The other anthropoids come nearer to Man than that. The chimpanzee is about 1 '30 mfetre ; the two or three species of orang from I'lO mfetre to 1'60 mfetre ; the gorilla from 140 mfetre to 1"73 mfetre, and more. Now the height of an adult man (France) is about 1 '65 mfetre, and this varies in every part of the globe from 1'30 mfetre to about 2 mfetres. Among pithecians, the cynocephali are generally the tallest; the nasious measures I'lO mfetre, the miothecus, 30 centimetres ; the cebians vary from 90 centimfetres in the brachyuri to 20 centimetres in the ouistiti; the lemurs are small. So much for the approximate measurements. How can we compare animals, some of which go on aU-fours, and others in a semi-inclined attitude, with Man, who is perfectly erect 1 Their general forms have more interest. Man varies so far as to merit the epithets tall and thin, or short and stout ; he is lean or fat, his neck is long or short, his abdomen drawn in or prominent. In the anthropoid apes the differences are also great. The gibbon is slender, long in the body, and made for agility, in this respect approaching to the semnopitheci ; he only wants a tail to make him resemble them in his movements. The orang, on the contrary, is duU, apathetic, and squat ; he walks with measured steps. The gorilla is remarkable for his athletic figure; he is said to wrestle even with the leopard, and to have the best of it. Both the oran" and the gorilla have monstrously prominent bellies, which belongs to their herbivorous or granivorous mode of feeding. The chim- panzee, though less muscular in his hmbs, and not so stout, has, like the gorilla, considerable strength. Among the Gaboon species we would mention the koolokamba, which, to judge by his skeleton, ought to have slender limbs. , Chap, ii.] PEOPOETIONS OP THE SKELETON. 81 Propoi-tions of the Skeleton. The proportions of the skeleton have also mtich interest. Their study having hitherto afforded more results ia the comparison hetween man and animals than in that of races hetween them- selves, we shall speak of them here in a general way. Osteometry. Osteometry, one of the most promising branches of anthro- pology, and one having an intimate connection with craniometry, is a study which has especial reference to the measurement of the facial angle and the direction of the occipital foramen, matters already considered. Osteometry itself is only a part of what should he called zoometry, which has to do with animals, in con- tradistiaction to anthropometry, which has Man for its object of study. Are we to seek for the proportion of the body on the skeleton or on the living subject? This is the question which governs all osteometry. On the Uviag subject one has the advantage of being able to refer each particular measurement to a unit of comparison, as stature, if we are dealing only with Man, or length of trunk or of the vertebral column, if we extend our examination to animals. But in spite of the greatest skiU. on the part of the preparator who mounts the skeleton, there is always somewhat of arbitrariness in the mode of articulating the bones, and of replacing the inter- vertebral substance with discs of leather. The bones are not found at all in the same condition when dry and when in the fresh state ; in the former case the cartilages are dried up, and so reduced in size that it is impossible to form any proper comparison between one skeleton and another. If we take a single articular extremity, the retraction of its investing cartilage is slight, but if we take the twelve surfaces of the entire hand, which are found between the tip of the fingers and the wrist, it amounts to something con- siderable. On the living subject, it is true, the measuring points are sometimes difficult to recognise, or are altogether inaccessible. G 82 EEOPORTIONS OF THE SKELETON. [Chap. n. To take the length of a femur, for example, as it is exhibited in the upright position, we place the two condyles fiat on the table, the bone takes its natural direction, and the length required is the projection comprised between the plane of the table and the. plane which is parallel to it, passing through the highest point of its head. On the living subject we have no means of obtaining any- thing of the kind ; the head of the femur is out of view iu the cotyloid cavity. Under these circumstances we are obliged to be satisfied with a different length, and we have recourse to other points of measurement — ^below, to the external side of the inter- articular space ; above, to the poLiit of the great trochanter, which is covered by a thick cushion of cellulo-adipose tissue, and the mass of fibrous tissue and tendons which have insertion in this tuber- osity, and whose consistence can scarcely be distinguished by the finger from the resistance of the osseous tissues. The same difficulties, althoilgh less in amount, are met with in the wrist, the elbow, and the shoulder. In a word, on the living subject we are enabled to make com- parisons of differences arising from stature, but from bad measur- ing points ; on the skeleton, to take perfect measurements, but to have no certain term of comparison. Another advantage of the measurements in the living subject is that they can be taken, by those interested in the study, in foreign countries, and upon a large number of individuals. Anatomists employ both methods. Some, taking care that the skeleton is properly mounted, give the particular length of each bone relatively to its height, or to the vertebral column. Others compare the bones directly together, without taking into account the height. For our own part we think the arbitrary mode in which the skeleton is mounted is exaggerated. The disposition of the articular processes of the vertebrae obliges the preparator to give, almost unconsciously, the proper thickness to the intervertebral discs ; his sources of error arise entirely from the drying up of the cartUages on the articular surface of these processes, amount- ing to fifty in the entire column. The skeleton of a gorilla, one of the tallest ever seen, mounted in America, was 1-650 Chap. II.] PROPORTIONS OF THE TRUNK. 83 metres in height ; the animal measured, immediately after death, 1-727 metres. Four gorillas were dissected in the Lahoratory of Anthropology, and their skeletons, -which -were afterwards mounted by M. Tramont, were less by three centimetres. These remarks have no reference either to the head or to the pelvis, whose internal proportions alone we generally study, hut simply to the trunk, the extremities, and their segments. Let us now proceed to results, referruig the reader to Chapter IV. of Part II. for a description of the usual methods of proceeding in taking measurements. Proportions of the Trunk. The first element of comparison which it is necessary to know, is the relative proportion of the trunk to the height of the hody. The length of the trunk can only he measured on the living subject, but the measuring points difier. The Americans, in their measure- ments made on a million individuals during the "War of Secession, chose as boundaries the spinous, or promiaent process of the seventh cervical vertebrae, and the perinseum. In their four series of measurements, which were taken with the greatest care, in from 207 to 1,064 individuals, the mean length was from 362 to 394- thousandths of the stature. Qu^telet takes from the cla-iricles above, and from the perinaeum below ; his mean is about 354-thousandths of the stature. In M. Seriziat's statistics, we have taken the interval between the biacromial line, or -width of the shoulders, and the biischiatic line, or -width of the seat; the mean was 362-thou- sandths. The length of the trunk in Man would then be more than one-third, and less than two-fifths of the stature. In the anthropoid apes there are less indications. In a goriUa killed by Du Chaillu, the distance from the seventh cervical vertebra to the point of the sacrum was about 440-thousandths of the stature. In M. Broca's laboratory, we have compared the length from the seventh cervical vertebra to the point of the sacrum in eleven skeletons of men, and one of the gorilla. Its relation to the stature was 366 in the latter, and varied from 292 to 340-thousandths in G 2 84 GEANDE ENVERGTJHE. [Chap. n. the former. The trunk of Man thus estimated would he shorter, hut only relatively, hecause his lower extremities increase his height. We are precluded, from want of space, from giving here the proportions of the thorax, and especially its circumference in Man and the animal. Grande Envergure. The relation of the grande envergure to the stature deserves our consideration. By the name grande envergure we understand the distance from the middle finger of one hand to the middle finger of the other, with the arms extended at full length hke a cross. This distance is ahout six centimetres shorter than that of the sum of the hiacromial diameter, and the length of the two extremities, taken in the ordinary way, from the acromion to the middle finger, hecause, in measuring the Umb in an extreme state of ahduction, the head of the humerus is buried in the armpit, and the limb is thereby shortened. The envergure exceeds the stature, in Man, variously from to 89 parts in the thousand. In a series of 10,876 American soldiers it was as 1-043 to 1-000. In the anthropoid apes, especially the gibbon and the orang, it is considerably greater. Its relation to the height was 1-654 in a gorilla, measured im- mediately after death, and about 1-428 in a chimpanzee of the bald species. "We see in a moment the enormous difference between these and Man. The proportions of the extremities have been studied by White, Humphry, Leharzic, Broca, Huxley, Hamy, Weisbach, Qu^telet, and Gould, in the adult man, and in some animals. We may now proceed to consider them both on the living subject and on the skeleton, but with the drawbacks we have mentioned. The first method for ascertaining the dimensions of the upper extremities, which exhibit the greatest difference between Man and the ape, is the grande envergure previously aUuded to. The second, stiU more simple, consists in noticing the exact point to which the extremity of the middle finger reaches in the position of the soldier standing at "attention." This extremity was separated from the upper border of the pateUa by an interval of from seven to twelve centimetres Chap. ii.J PEOPORT^ONS OF THE EXTREMITIES. 85 in the mean results obtained on soldiers of different races in the American army. According to Mr. Huxley, the hands reach the middle of the thigh in Man, below the knee ia the chimpanzee, the middle of the leg in the gorilla, the antle-bones in the orang, and the ground in the gibbon. The direct measurements which we are about to mention are preferable. Proportions of the Extremities. The relation of the superior to the inferior extremities is different in Man and the anthropoid apes. It is easily obtained by measure- ments taken on the living subject, but the measuring points sadly vary among different observers. It is obtained still better on the dry bones, whose length is added, leaving out the hand and foot, which do not appear the same in the upright posture, the one giving its long axis, and the other only its thickness. The first figures we quote are those of Mr. Huxley, which have no reference to the stature, but to the entire vertebral column from the atlas to the point of the sacrum = 100. This is very useful for making the comparison with animals, and especially quadrupeds.* The two men are a European and a Bosjesman, the extremes of the group. Superior extremity less the liand. Inferior extremity less the foot. 2 men 79 ... 113 1 cMmpanzee 96 ... 90 1 gorilla 115 ... 96 1 orang j_i__' 'i . 112 /-t\ rT^^__. . i_ ^ ... 88 1 *j * 1 I Prom this it appears: (1) That the upper extremity is shorter and the lower longer than the vertebral column, while this is the reverse in the anthropoid apes, with the exception of the upper extremity of chimpanzees ; (2) That of the two extremities, the upper is shorter and the lower longer in Man, whilst this is the reverse in. anthropoids. But the cases before us are not sufficiently numerous, and the measurement was made upon the mounted skeleton. * "Man's Place in Nature," by T. H. Huxley; translated into French by E. DaUy. Paris, 1858. 86 PROPORTIONS OF THE EXTREMITIES. [Chap. n. Dr. Humpkry* has taken lus measurements independently, and lias made tkem bear relation, not to tlie column, but to the entire height of the individuals examined. Of his fifty men half are Europeans and haK negroes.

Then we must compare the absolute length of the additional bones directly with each other. To this end we have measured eighteen anthropoid apes, the largest number upon which any one observer has practised. We will give their measurements together with those made on Man, published by M. Broca.+ The following table shows the relation of the sum of the humerus and radius to the sum of the femur and tibia, the latter being taken as = 100 : H + E : F + T. somen 689 8 gorillas 101-3 9 chimpanzees ... ... ... 108'2 1 orang ... ... ... ... 140-4 The deductions are the same.

Chap, ii.] EELATION OF THE EADIUS TO THE HUMERUS. 87 or the alDsolute measurements, the result is the same. The upper extremity, from the wrist to the shoulder, is shorter ia Man, longer in the anthropoid ape, than the lower extremity from the instep to the articulation of the hip. The respective proportions of the two segments which enter into the constitution of each wiU. throw further light on the matter. Relation of the Radius to the Humerus. The relation of the radius to the humerus, or of the forearm to the arm, iirst received attention ia 1795, by "White, who thus be- came the founder of osteometry as applied to Man. By measure- ments made on the living subject, and on the skeleton, he proved that the forearm of the negro is longer than that of the white races. His researches, which had long passed out of notice, were revived by Lawrence in 1817. Mr. Humphry again took up the question in 1858, embraced the lower extremities in his measure- ments, and extended the comparison between Man and the anthro- poid apes. Lastly, ia 1862 and ia 1867, M. Broca casuaUy touched upon the subject ia the two memoirs before referred to.* There are more or less marked shades of difference ia the relative dimensions of the bones of the extremities, and before inquiring into them it is weU to bear in miad the general fact. The radius is always smaller than the humerus, and the tibia smaller than the femur ia the human skeleton. It is the same in the goriUa and the chimpanzee. The same may be noticed in the tibia of the orang, while the radius is perceptibly equal to the humerus, which proves that the proportions are not the same ia aU the anthropoids, and differ as ia the human races. The followiag table gives the relative proportion of the radius to the humerus, 100 being taken as the length of the latter. The first column has been calculated with the measures of Mr. Humphry * Eeferenoee to books ooonpy so mucli space that we can only give the more important ones. The researches of White are to be fomid in his memoir, p. 14 ; in Lawrence's work, p. 14 ; that of Humphry, p. 85 ; and that of M. Broca, p. 86. 88 RELATION OF THE TIBIA TO THE FEMUR. [Chap. ii. upon the 50 men and the 8 anthropoid apes previously alluded to, and the second with those of M. Broca upon 30 men of all races, and with our own upon 18 anthropoid apes : Humphry.

The difference between Man and the ape is not great, looking at the proportion between the upper and lower extremity, but it is not the less certain. In f[uestions of proportion a slight matter materially alters the result. The radius is shorter compared with the humerus in Man than in the anthropoid ape. As the number of gorillas and chimpanzees in the two lists amounts to 22, the question may be regarded as settled so far as they are concerned. It is less so as regards the three orangs, which, taken together, show the relative length of the radius to be 9.5-2, pre- suming that we regard this bone as longer than in the two other kinds of anthropoids. The relative proportion of the tibia to the femur, the latter being taken as = 100, is given in the following table, in the same subjects as in the one preceding : Humphry. Broca and Topinard. Man ... 82-6 ... 80-6 Gorilla ... 84-7 ... 77-8 Chimpanzee ... 84-5 ... 78-7 Orang ... 86-6 ... 85-7 The results appear to contradict each other. According to those of Mr. Humphry, the tibia would be shorter than that of the apes. According to ours, looking at the greater number of gorillas and chimpanzees, which makes the matter stUl more decisive, the human tibia would, on the contrary, be longer, our single orang being left out of consideration. Some of the differences in these Chap, ii.] PROPORTIONS OF THE FOOT AND HAND. 89 two lists are probably attributable to the metliod of calculating, M. Broca and myself having left out the internal malleolus, and Mr. Humphry having probably included it. The main point is that each of us has proceeded in the same way in all the series. We admit that the second segment of the lower extremity is gene- rally shorter iu the anthropoid ape, whilst that of the upper is longer. Might not the two conditions be explained in the same way ? The leg would be shortened in the ape because his lower extremity is less exclusively employed in progression ■ his fore- arm would be lengthened, on the contrary, because the upper extremity, in addition to its function of prehension, contributes to progression. The relative proportion of the humerus to the femur, the latter taken as = 100, has also been a subject of study. Our figures and those of Mr. Humphry represent it as follows : Humphry. Broca and Topinard. Man ... 71-1 ... 70-7 Chimpanzee ... 90-8 ... 100-5 Gorilla ... 110-2 ... 113-4 Orang ... ... 131-6 ... 128-6 With some minute shades of difference the conclusions arrived at are similar. The humerus is shorter in proportion to the femur in Man, and longer in the anthropoid apes. We may hence infer, by taking into consideration the greater length of the upper arm in the anthropoids, and the greater length also of the radius, that the two bones contribute, each in its degree, to the lengthening of the whole limb in these animals. Thus a long humerus, a stiU longer radius, a short femur, a still shorter tibia, such are simian characters, the more human being the very reverse. The relation of the foot and the hand to the stature, or to the rest of the corresponding limb, can only be examined on the living subject. Later on we shall . give their relative lengths in the human races, the term of comparison faihng us as regards the anthropoid apes. But, for want of a better, we shall give the Gorilla ... 14,-54 Chimpanzee ... 18-00 Orang ... 2083 90 VARIOUS CHARACTERS. [Chap. ii. measTirements relatively to stature taken on the skeleton by Mr. Humphry : Hand. Foot. Man 11-82 16-96 20-69 21-00 25-00 The foot and the hand are thus shown to become larger as "we pass from Man to the anthropoids, and progressively so in the three mentioned above. We shall say nothing of the relation of the clavicle to the humerus, concerning which but little has been recorded. Such are the primary results with regard to the comparative proportions of Man and anthropoids. Can we say anything further as to the near affinity of one of them to Man ? The question is only doubtful as between the gorUla and the chim- panzee. In every instance recorded in our list the orang occupies the most remote position, except as regards the tibia in the siugle case in our list which the two cases of Mr. Humphry nullify. The gorilla has the whole of the upper extremity, including the radius and the hand, more human, while in the chimpanzee the resemblance is only as regards the humerus and tibia. In considering only the two upper segments, each seems to have an advantage ■ in its way, the gorilla by his shorter forearm, the chimpanzee by his shorter arm. The length of the upper extremity and of the hand have, however, the greater weight in the balance, and we should give it in favour of the gorilla. But in the long bones, as well as in the vertebral column and skull, there . are characters besides the dimensions which as yet have been but little studied. Only to take one example : the greater obliquity of the femur, the greater angle which its neck makes with the diaphysis, and the comparative slenderness of the entire bone give the advantage to the chimpanzee, and especially to the koolokamba species. It is indisputable that the proportions of the skeleton are very different in the four kinds of apes, although in their general type there may be much similarity. We will say more : they differ even in the species of one and the Chap, hi.] MUSCLES. 91 same genus; ■wMch it telioves us to consider, when, during the prosecution of these studies, we shall have more subjects at our command. We shall consider this relation of the anthropoid apes in general, as weU as of men in general at a future time.

The study of the muscles naturally follows that of the skeleton. Their arrangement throughout the whole mammalian series is dependent on configuration, and on the Tarious functions of movement. In no part of the organism is there to he found a more palpable demonstration of the great physiological law that " use makes the organ," than in the wasting away of those parts which are not in use, and the hypertrophy of those constantly at work. K"evertheless the type varies somewhat : the muscles are the same, but at one part a muscular fasciculus becomes strong or is reduced to a mere vestige ; at another a portion is detached, or subdivided, or its insertions are a little nearer or a little farther off. The muscles of the monkey are so like those of Man, that up to the fifteenth century, descriptions of them absolutely took the place of the latter. We are indebted to Andr6 Vesalius for having shown that the dissections of Galen were never carried on but upon monkeys. The resemblance is stiU more perfect in the anthropoid apes. We shaU. confine ourselves to mentioning some of the differences which we find among anthropoids. The cutaneous muscle which is so developed in the majority of mammalia, as well as iu the ordinary monkeys, for the purpose of contracting the skin, is concentrated in the cervical region in the anthropoid apes, where 92 MUSCLES. [Chap. hi. its size is almost equal to tliat of Man. The -whole of the cervical muscles, whose development in quadrupeds and iu the inferior monkeys is in proportion to the necessity of maintaining the head in the horizontal position, have merely an importance in the anthropoid apes and ia Man, commensurate with the oblique attitude iu the former and the upright ia the latter. The trachelo-acromialis muscle of Cuvier, which is met with in many of the mammalia, and especially in monkeys, is wanting in Man, as well as in the gorilla and the chimpanzee ; it seems to be merely a supplement to the elevator scapulae, which Man possesses also. The great rectus abdominis muscle, which has generally four aponeurotic intersections in mammalia (Cuvier), and seven in the cynocephali, has but five in man, in the chimpanzee, and in the gorilla. It is said that the anthropoid apes have a long abductor of the great toe more than Man, but it is merely a fasciculus of the tibialis anticus muscle. It is also said that they have a short extensor of the great toe, and an extensor digitorum with three tendons instead of four as in Man ; but it is a misinterpretation of the same fact. The extensor of monkeys is in reality the counter- part of the same muscle so irregular in Man. So with regard to the black cliimpanzee. It is said to have no proper extensor indicis. Two chimpanzees in M. Broca's laboratory, however, had it. Nevertheless, between Man and the anthropoid apes there are differences, though they are but slight. The situation and the inser- tions of the pectoraHs minor vary in the two groups, and in that of the inferior monkeys ; but these variations are less recognised between the two former than between the anthropoid apes and the group next to them. The short flexor of the thumb, so powerful in Man, in anthropoids is atrophied, and blended with the deep flexor of the fingers, which is connected with the index. A tendon of this last, in the gorilla, is inserted into the thumb, and assists in the movement of flexion. The same tendon in the orang and the gibbon is furnished by the adductor of the thumb. In place of the proper extensor of the index and of the extensor Chap, hi.] MtTSOLBS. ya of the little finger, the orang and the ordinary monkeys have only one muscle, -with four tendons supplying the four fingers, not taking iato consideration the common extensor of the fingers ia either case. In the foot the differences are not so great. The great toe, on ■whose pretended movement of opposition an entirely erroneous system has heen hased, is suppHed by the same muscles as ia Man. Nevertheless, owing to its more lateral insertion into the meta- tarsus, it is found that the long lateral peroneal muscle contributes partially to its flexion. The transverse adductor of the great toe, rudimentary in Man, is well developed in monkeys. The flexors of the toes differ some- what in Man, and in the anthropoids ; but what the movements gain in force and extent in the latter, they lose in independence and precision in the former. In the orang the long flexor of the great toe is entirely wanting. The sole muscular peculiarity by which the anthropoid is really separated from Man and is brought into closer affinity with the ordinary monkeys, is the existence in the arm of a fasciculus called the accessory of the latissimus dorsi, which does not exist in Man, and is inserted superiorly into the tendon of the latissimus dorsi, and inferiorly into the head of the humerus. It has also been observed in a rudimentary state in some negroes. Two features of the muscular system have been noticed as distinctive of Man and animals, especially monkeys. These are the prominence of the buttocks and of the calves of the legs, owing to the development of the gluteal muscles and of the triceps, to which is due the strength of the tendo achillis. Such is the fact, and is a result of the biped attitude. The use of the gluteal muscles especially is to keep the thigh extended upon the pelvis. But in both respects the gorilla, casts of whose muscles have been taken from the sub- ject, and reproduced in pasteboard by M. Auzou, is unquestionably more favoured than some negroes. Moreover all the minute, or at least the more important points, which seem peculiar to the anthropoid, are found from time to time in Man, and especially in the negro race. M. Chudzinski, 94 OEGANS OF SENSE. [Chap. iii. preparator to tlie laboratory of the Ecole des hautes .Titudes, has already published two exoellent memoirs upon this subject.* Organs of Sense. In these is included the cutaneous envelope •which smrounds the body, protects it against external agencies, and is the seat of the ftmction of touch. One of the characters ■which distinguish the class of mam- malia from that of birds, fishes, and reptiles, is the presence of hair upon the body. De BlainviUe proposed to substitute for his designation that of pilifhres. Some, however, have the skiu naked, as certain cetaceae. The characteristic of man proposed by Lin- naeus, therefore, is anything but a correct one : homo nudus et inermis. Man really has hair not only on the head, on the face, under the armpits, and on the pubis, but over the whole of the body, and in certain races quite a thick crop on the chest, behind the shoulders, and on the limbs, resembling down, and masking the colour of the skin. The history of Esau is a most probable one. Compared with the majority of mammaha, and in particular of monkeys, Man is the least hairy ; the palms of his hands and the soles of his feet are alone without hair, which is to be accounted for by its having worn away. The smooth and indurated surfaces on the buttocks, called callosites fessieres in the pithecians, are wanting in the anthropoid apes, with the exception of certaiu gibbons, as well as in the cebians and lemurs. The naUs, claws, and hoofs of mammaha are a secretion from the skin, like hair and horns. The presence of flat naUs, not bent round, on the fingers and toes, has been given as a characteristic of Man. We must, therefore, associate the anthropoids with him. The orang alone forms a partial exception, having no nail on the great toe. Flat nails are found in the pithecians ; they are bent * " Contribution k I'Anatomie du NSgre et Nouvelles Observations sur le Syet^me Mnsoiilaire du Nfegre," by T.

The ouistitis, some other ceMans, and the arctopithecians have claws, except on the great toe. In lemiirs it is the reverse : the claw is found on the great toe, and nails on the other toes. The arrangement of the wriukles and of the corpuscles of Pacctni in the palm of the hand has reference to the function of touch. In Man, there are two principal wrinkles in the hand, one pro- duced hy the flexion of the last three fingers, the other hy the flexion of the thumb, and passing round the eminence, thenar ; a third, which is variable, and between the two, is joined at its external extremity with the latter, and is free, and nearly paraHel with the former at its internal extremity. According to M. Alix, the fold of the thumb is wanting in the monkey tribe, and the other two are united to form one. The fact is evident in the three inferior groups, but doubtful as regards the first. If some anthropoids exhibit in consequence of this an inferior simian arrangement, Man is exceptionally in the same position. The corpuscles of Paccini, or tactile corpuscles, are little bodies situated in the direction of the nervous filaments of the palmar surface of the hand and fingers, and of the plantar surface of the foot. M. l^epveu has shown that their appearance under the microscope is alike in Man and the chimpanzee, whilst it is somewhat different in the common monkey, the baboon, and the sajou. The organ of vision is similar in Man, the anthropoid apes, the pithecians, and the cebians. But in many lemurs, the fundus of the eye assumes a glittering appearance, which in the cat and the ox has received the name of tapetum. A Httle muscular fasciculus also exists, analogous to the musculus choanoides found in the majority of quadrupeds. The nose, anatomically the same ia Man and the monkey tribe, presents merely morphological changes. Sometimes projecting in the former, in a less degree however than in the nasicus, one of the pithecians, it is at other times more or less flat, as in the generality of monkeys. The nostrils are, usually directed downwards, as in the anthropoid apes and pithecians, and sometimes sideways, as in 96 VISCERA, [Chap. hi. cebians ; two arrangements wliioli have suggested to Geoffroy Saint- Hilaire his division of monkeys into catarrhini and platyrrhini. The septum is comparatively thin in the catarrhini, and thick at the anterior triangular border in the platyrrhini. The cartilage of the ear, whose form and length are so variable in different mammals, in monkeys is usually strong, having no fold behind ; it is sometimes square above, and rounded off, and is without a lobule. These arrangements are occasionally found in Man. On the other hand, the ears of the gorilla and the chimpanzee are often as well folded as those of Man. The pithecians have two pouches, named cibqjous, which open in the mouth — ^the anthropoids, like Man, having nothing of the kind. Viscera. The length of the alimentary canal is about six times the length of the body, or about eleven mfetres, according to M. Sappey. In carnivora it varies from two to eight times, and in solipeds and ruminants from ten to twenty-eight times ; in monkeys it is from five to eight times, in the gibbon about eight. The stomach of all the monkey tribe is simple as in Man. The semnopithecians and the colobians are exceptions ; their stomach if not multiple, is at least multUocular, resembling the herbivora in this respect. The commencement of the large intestine, or csecum, lies in the right iliac fossa, as in Man, and is covered in front by the peritoneum. In pithecians, the csecum is, on the contrary, enveloped by the peritoneum, which forms one of the folds of the mesentery behind, and is designed for the purpose of facilitating the mobility of that part of the intestine. In the anthropoid the peritoneum surrounds the caecum, as in Man. An appendix, the vermicular, is annexed to the human csecum. It exists also in anthropoid apes, but is wanting in the monkeys below them, with the exception of some lemurs. The liver of Man has, properly speaking, only two lobes ; in anthropoid apes it is similar. In the other monkeys, on the contrary, it is very much subdivided, as in the lion and the rabbit. Chap, in.] PEfllTONBtTM AND PERICARDIUM. 97 M. Broca in his memoir, " Sur les Primates," has drawn attention to the variations of the peritoneum, the serous memhrane which is reflected round the organs in the abdominal cavity, and has for its ohject to isolate them, and to allow them to glide smoothly upon one another. His opinion is, that the arrangement of the peritoneum does not perceptibly differ in Man and the anthropoid apes, whilst in passing to the pithecians it immediately exhibits marked differences. The distinction of mammalia into bipeds and quadrupeds may to a certain extent be recognised by the arrangement of their internal organs. The marked peculiarity of the peritoneum in its relation to the caecum may be specially mentioned. In the chest we see differences of the same description. The pericardium, or membrane surrounding the heart, is to this organ what the peritoneum is to the intestines. In Man it is altogether separated from the sternum and is attached to the diaphragm, a transverse muscular septum which separates the thoracic from the abdominal cavity. In quadrupeds it is firmly fixed to the sternum and to the articulations of the ribs, and is not attached to the diaphragm. In the former, indeed, the heart lies on the diaphragm, in the latter on the sternum, in accordance with the attitude of the animal. In monkeys the arrangement is inter- mediate; in lemurs the pericardium does not adhere to the diaphragm except to a very limited extent ; in cebians and pithe- cians the surface attachment increases in size. In the anthropoid apes the pericardium is as in Man. Similar changes occur in the direction of the heart, in the length of the vena cava inferior, and in the curve of the aorta near its origin. In quadrupeds a result of the non-attachment of the heart to the diaphragm, is the interposition between the two of a lobule of the right lung. This lobule, known by the name of impar, exists throughout the whole mammalian series, from the marsupialia to the carnivora, and is wanting in Man. In the lemurians and the cebians it is also developed. In the pithecians it becomes less ; in the gibbons it is almost nil; in the orang, the chimpanzee, and the gorOla there is not the slightest trace of it. H 98 THE LARTNX. [Chap. ni. From the viscera we now pass to tlie vessels, wliere we shall always find a confirmation of the same fact — ^namely, that the organisation of anthropoids is a counterpart of that of Man, and difiers widely from. that of the other simian groups. "We shall say a few words respecting the larynx and the organs of reproduction hefore entering upon a study of the very Jtiighest importance — ^that of the brain. The Larynx. The larynx, or organ of voice, is at the upper extremity of the windpipe, where the glottis is situated, through which the air is respired. It is composed, like the trachaea, of cartilages, though much larger. The two principal ones are the cricoid below and the thyroid above. It is closed at certain moments by another cartilage, which acts like a valve, and is called the epiglottis. In aU essential points this little apparatus is identical throughout the entire mammalian series, and notably in that of monkeys. Upon four points of its extent — that is to say, below the cricoid, between it and the thyroid, between the thyroid and the epiglottis, and between the vocal chords — are seen occasionally dilatations or ampullss, which have considerable importance in anthropoid apes; some median and single — giving rise to three primary anatomical varieties — others lateral and double, forniing a fourth. The first, or tracheal variety of dilatation, is observed in the horse, the ass, and in the coaita, one of the monkeys of the cebian group ; the second in two other kinds of cebians ; the third in a lemur, a cebian, two pithecians, and a gibbon. The fourth variety exists ia a rudimentary state in Man under the name of arriere-cavite, or ventricle of the larynx,* and attains with age, in the three higher anthropoids, an enormous development, especi- ally in the male, and is known in them under the name of air sac. In a young chimpanzee dissected by M. Broca, it formed * M. Sappey described it under the name of portion verticale of the ventricles of the larynx. It is situated, he says, at the upper border of the thyroid cartilage, close to the hyoid bone, and in rarer instances reaches to the base of the tongue, and extends under its mucous membrane.

In the ao-ed gorilla and orang the projections become larger, and run under the sterno-mastoid muscles, under the trapezius, envelop the Fig. 14.— Vertical and antero-posterior section of the face and neck : a, Bodies of the cervical vertebrae : m, Basilar process, or body of the occipital bone : 'rt, Floor of the anterior cerebral fossa ; o, p, q, Superior middle and inferior shells of the nasal fossae ; l.

They are, in fact, veritable hemise. In a morphological point of view, these sin- gular organs establish an important difference between Man and the anthropoids in question; but, in an anatomical point of Adew, the difference is nil ; it is the same organ, only of a dif- H 2 100 ORGANS OF REPRODUCTION. [Chap. hi. ferent size. We may add, lastly, that the true air sac is absolutely wanting iu aU the other apes, so that this, which appears to establish a character between Man and the anthropoid, shows, on the contrary, their relationship, and the distance of the latter from others of the monkey tribe. Organs of Beproduction. The characters which they furnish are those to which we attach the greatest value in the various departments of natural history ; the class mammalia is, indeed, based upon them. AK mammalia are viviparous — ^that is to say, bring forth their young aUve — and aU have teats. These glands vary in number, generally being equal to that of the young which they bring forth at a birth, and they vary also in situation. The cat has 8; the bitch, 10 ; the agouti, 1 4 ; woman, 2, although generally she has but one child at a birth. They are abdominal in the carnivora and the marsupialia ; iuguinal in soUpeds and ruminants ; and pectoral iii the woman, the elephant, and the lamantin. In this twofold point of view, monkeys, including the anthropoid apes, are con- structed after the type of Man. Many lemurs have four teats — two pectoral and two inguinal, some macaucos having four pec- toral ; aU the others have two teats, attached to the breast. Among mammalia, a few", as the marsupials, have no placenta — that is to say, an intermediate fleshy substance between the embryO' and the uterus ; others have one, called en zone, when it occupies a considerable surface of the internal parietes of the uterus, or e?i disque when it occupies only a smaU portion. Man, the monkey tribe, the rodentia, the inseotivora, and the cheiroptera belong to this category. There is some diflference between them however.. In Man the placenta is single, and the umbilical cord is composed of one vein and two arteries. In cebians it is stiU single, but it is furnished with two veins and two arteries. In pithecians- it is double ; it has, however, only one cord, formed of one vein and two arteries. In which arrangement do the anthropoids ap- Chap, hi.] CEEEBBO-SPINAL AXIS. 101 proaoh to them? The gibhon, which usually holds the transi- tional position between them and the pithecians, has, like them, a double placenta. In the chimpanzee, on the contrary, it is single, as in Man {Owen). The orang and the gorilla have not been examined on this point. After the descent of the testis into the scrotum in Man, the peritoneal communication is obliterated ; in other mammalia it is persistent. JSTothing is yet known as to this in anthropoids. The same may be said with regard to quadrupeds generally. The uterus in them has two comua, and is divided into two cavities. That of woman is, as a rule, unilocular ; that of ordinary monkeys holds a middle position. Nervous System. In the Invertebrata it is composed of little masses of gray sub- stance interspersed through the viscera, and attached to them by nervous filaments. In the Vertebrata there is, in addition, another and a symmetrical apparatus, consisting of an axis, called the cerebro-spinal, of centrifugal nerves for movements, and of centri- petal for impressions. The essential differences between them are to be found at the superior or anterior extremity of the axis or encephalon, which we shall first describe as it exists in Man. The spinal cord, called medulla oblongata at the level of the fiist cervical vertebra, passes through the occipital foramen, beneath the transverse fibres which unite the two lobes of the cerebellum under the name of ^oms varolii, and divides into two fasciculi called the cerebral peduncles, one to the right the other to the left ; they then spread out into two fan-like expansions of white fibres, pass upwards and outwards, bend down at the borders like a mushroom about its stalk, and go to form the cerebral hemispheres, on the surface of which is a layer of gray substance. The white portion is the conducting matter, the gray the sentient and reacting. At the internal contiguous borders of the hemispheres the white transverse fibres become bound together to form the corpus caUosum. Each 102 BNCEPHALON. [Chap. hi. is surrounded by a canal, forming a series of cavities, of whicli the principal are tte lateral Tentricles, wMcli exhibit thiee cornua : the anterior or frontal cornu, the inferior or temporo-sphenoidal, and the posterior or occipital — the last presenting an elevation on its floor caUed hippocampus minor. The encephalon consists of (1) The cerebelliTm; (2) The portion lying between its two lobes connecting the medulla oblongata with the brain — the pons varolii, or protuberantia annularis ; (3) The brain proper, formed by the peduncles and the series of expansions which proceed from them — ^viz. the tubercula quadrigemina, the optic thalami, and the corpora striata — by the ventricles, and by the cerebral hemispheres, the surface of which exhibits sinuosities. The priucipal sinuosities are called convolutions, and the secondary ones, folds. The external surface of the brain occupied by these is divided into distinct portions or lobes by fissures, and the convolutions of which these lobes are composed, by sulci. The communications between the lobes are called transition convolu- tions {pits de passage), and those between one convolution and another in the same lobe, anastomoses. From the base of the encephalon arise the first twelve pairs of nerves, or encephalic nerves. The first are the olfactory, the bulbous portion of which — called the olfactory bulb — lies longi- tudinally in a depression on the surface of the anterior lobe ; the second are the optic, whose decussation at the median hne is called the chiasma. When we place the encephalon on its upper or convex surface, and remove the cerebeUum and pons varolii by a transverse section passing between the junction of the latter with the cerebral peduncles, the whole inferior surface of the two hemispheres is exposed to view (Fig. 15). At the junction of the anterior third with the posterior two-thirds is seen a deep transverse fissure, with its concavity looking backwards. This is the fissure of Sylvius (A, Fig. 16). The portion in front is the inferior surface of the frontal or anterior lobe ; that behind is the inferior surface of the posterior lobe, which is separated into two weU-marked Chap.

[Chap. hi. under one aspect, sometimes under another. We prefer the latter method. Each hemisphere has an internal surface, which looks towards the median line, and an external. The first thing which strikes the attention on looking at the external surface is the fissure of Sylvius, which has passed round the inferior border of the hemisphere, and whose external surface is shown at A, Fig. 1 6. It is divided into two branches, which unite in the form of a V. The anterior and vertical is very short, and is lost in the anterior lobe ; the posterior is longer, and passes obliquely backwards and a Httle upwards, having below it a large elongated and very distinct cerebral lobe, which is the temporo- sphenoidal lobe already seen from underneath. The fissure of Sylvius corresponds on the skull with the superior border of the squamous portion of the temporal {Broea). There is no mark of equal importance to this on the external surface of the brain, and it is asked how we contrive to make any other fundamental division. It is, however, in the midst of the sulci, apparently so complicated, that we take the fissure of Eolando (B, Kg. 16) as the line of separation of this surface into the anterior or frontal, and the posterior or parieto-occipital lobe. It is constant, and, in. the foetus, the most clearly defined after the fissure of Sylvius. Its situation and direction are nearly the same in aU healthy brains. It commences some millimetres above the fissure of Sylvius, and passes vertically, or rather a little obHquely, backwards, reaching to within a few millimetres of the superior border of the hemisphere. Its obliquity and its situation are indicated by the two following relations : The total length of the brain being reckoned as 100, the portion in front is to that behind as 43-0 to 57'0 at the inferior extremity of the sulcus, and as 56-3 to 43-7 at its superior. It follows from this that the middle por- tion should be equidistant from the two extremities of the hemisphere. M. Hamy calculates that the inclinajtion of the sulcus in the adult is about 70 degrees. Gratiolet thought that the fissure of Eolando corresponds exactly, on the skull, with the coronal suture. M. Broca was the first to notice that, in the European, it is always from 40 to 56 millimetres Chap, m.] CONVOLUTIONS. 105 "behind it at its upper part, 47 in the middle, and 15 at the lower part.* A second fissure marks another division of the external surface of the hemispheres — namely, the external perpendicular fissure (E E, Fig. 16). It separates the posterior lohe into two, the parietal and the occipital lobe, and on the skull answers to the lambdoidal suture, beiag distant from it about two millimtoes. In order to discover it, the student should look for it from its pro- longation on the floor of the hemisphere, to a few centimetres from the posterior extremity, where it takes the name of internal per- pendicular fissure. It is so caUed because it exactly separates, from below upwards, the most remote part of the hemisphere, to form of it an occipital lobe. We have then (1) An anterior or frontal lobe, bounded behind by the fissure of Eolando; (2) A middle or parietal lobe, included between the latter and the external perpendicular fissure ; (3) A posterior or occipital lobe, situated behind the perpendicular fissure ; and (4) An inferior or temporo-sphenoidal lobe, subjacent to the long branch of the fissure of Sylvius. Such are the important divisions on the external surface of the hemispheres. We shall now describe those of the internal surface, as well as its convolu- tions. Convolutions. The acts of transmission in the brain, which have reference to altogether voluntary movements, to certain refiex movements, to sensations, or to certain phases of intellectual operations, have for their seat the fibres of which the central white mass of the hemi- spheres is formed. The initiative acts of thought pass, on the contrary, through the gray substance which constitutes the cortical portion of these hemispheres. Consequently, the greater the amount of gray substance, and of surface upon which it can be developed in a continuous layer, the more power the truly intel- lectual phenomena acquire. To this end, the surface is folded and * " Sur ]a Deformation Toulousaine du Crane," by Panl Broca, in " Bull. Soc. d'Anthrop.," 2nd series, vol. vi., 1871. 106 CONVOLUTIONS. [Chap. iir. contorted, so as to increase its extent. Such is the office of th& convoliitions, elongated and tortuous swellings, separated hy sulci more or less deep. It was long thought that their arrangement was inextricable and the result of mere chance. This is an error r the complexity is only apparent. They consist of fundamental parts, or convolutions, properly so called, whose type is constant throughout the human series ; and of secondary parts or folds, which exhibit variations between one individual and another, similar to those which the features of the countenance present. The brain of the foetus at the beginning is smooth. The fissures appear first, then the sulci. At the seventh month the convolu- tions are simple but formed ; at birth it is the same with the folds. At a later period the whole is completed. The convolutions become enlarged and more complex as age advances, in proportion to the activity which the organ exhibits. A convolution would be rectiliaear in a subject of tolerable intelligence, as in the patient of Bicetre, whose brain we have now before us. In another subject of superior intelligence it would be tortuous, double, and altered in form, by the pressure of neighbouring redundant convolutions. The sulci woidd be hidden, and the anastomosis between one convolu- tion and another, ia a rudimentary state in the former, while in the latter it would be considerable, and would cause a change in the configuration of the primary convolution. This, which is caUed the richness of the convolutions — that is to say, their development in number and tortuosity, causes not only an absolute increase in the quantity of these convolutions, but also a reduction in size of each of them taken singly. Large and simple convolutions are thus a sign of idiotcy, or of weak intellect, in any race. Small convolu- tions with numerous foldings are a sign of large intellectual capacity. However, by carefully studying the brains of monkeys, of the foetus, of infants, and of idiots with simple convolutions, all this is explained.

[Chap. in. of Sylvius — that is to say, its base, and the parts belo-w and above. The base only deserves mention as regards the point of the V. By separating the two lips at this point we discover a weU-marked ttiberole, called insula of Eeil, and also central lobule, because it is situated in the exact line of the cerebral peduncles ; it is ocpupied by five or six shallow folds, which radiate from its inferior angle. The region below, or temporo-sphenoidal lobe, forms a large mass, obhquely directed from below upwards, and from behind forwards, and is traversed in the same way by a sulcus, which is parallel to the fissure of Sylvius, and which on that account is caUed the parallel sulcus (C). From its posterior extremity a small cul-de-sac passes to the centre of the parietal lobe, and sometimes a prolongar tion towards the occipital lobe. A second sulcus is observed below, but of much less importance. The intermediate enlargements are termed the first, second, and third temporo-sphenoidal convolutions (11, 12, 13), the third or inferior appertaining also to the inferior surface of the brain. The region above includes both the frontal and the parietal lobes, separated by the fissure of Eolando, whose two lips form two of the most distinct convolutions of the whole system of the external surface. Having the same direction as the sulcus which separates them, one belongs to the frontal lobe and takes the name of anterior ascending convolution (7), the other 'to the parietal lobe, and is called the posterior ascending convolution (8). The frontal lobe, so important in Man, since it is in it that his highest faculties reside, consists of three regions : one, which we shall find on the external surface ; a second, which is seen on the inferior ; and a third, the most important of all. The second rests upon the roof of the orbit, and comprises three or four smaU convolutions of but little interest : one bound up between the sulcus of the olfactory nerve and the internal border of the hemisphere, and which forms the termination of the first frontal convolution; the other two being in continuation, in the same way, with the two frontals on the external surface. The frontal region proper of the anterior lobe comprises four convolutions : an anterior or frontal ascending, already mentioned, Chap, hi.] FRONTAL LOBE. 109 and three longitudinal and parallel, superposed in three storeys. The first, or superior frontal convolution, arises by one, and some- times by two roots from the superior extremity of the ascending, becemes double, skirts the superior border of the hemisphere, and is lost in the orbital region. The second, or middle frontal con- volution, arises also behind, by one root, and bifurcates occasionally to give an anastomosis to two adjoining frontal convolutions. The posterior part of the sulcus, which separates it from the third, cor- responds, according to M. Broca, to the curved temporal line of the parietal. The third, or inferior frontal convolution, commences in the most sloping portion of the ascending frontal, forms a large gyrus round the small branch of the fissure of Sylvius, and loses itself in front. M. Brooa's way of looking at it is somewhat different. He merely brings in the ascending frontal convolution to assist in the description. According to him there are only three frontal convo- lutions, all antero-posterior and parallel, including, at the back, the portion of the ascending convolution where each takes its origin, which must not be forgotten when discussing the localisation of th^ faculty of language. We know indeed that there is aphasia — that is to say, loss of speech ; or aphemia — that is to say, loss of speech with preservation of the intellect, whenever an acute lesion occurs at the posterior part of the third frontal convolution of Broca when this lesion is on the left side. The faculty of language has its seat on botb sides, but it is put in exercise from this side in the greater number of cases. Its surface has a vertical extent of about four centimetres, and an antero-posterior of from two to three and a half. Its form is that of a quadrilateral, bounded in front by the smaU branch of the fissure of Sylvius, and behind by the base of the fissure of Eolando. Its centre corresponds, on the external part of the skull, with a point situated about one centimetre and a half behind the coronal suture, and three centimetres above the pterion.* * " Sur le Si%e de la Faculte du Langage Articule," by P.

[Chap. hi. The next, or parietal lobe, included between tbe border of the hemisphere above, the fissure of SyMus, and the temporo-sphenoidal lobe below, and the perpendicular fissure behind, is formed by three convolutions. The first, or posterior, ascending, has been described. The second, or superior parietal convolution (9), commences by one or two roots towards the middle and superior portion of the posterior ascending, describes a number of vertical flexures which reach to the superior border of the hemisphere, and form a smaU. lobule, which is very easily recognised. The third is below, and is separ rated from it by a transverse sulcus, called the interparietal sulcus (D) ; it arises at the inferior part of the posterior ascending, in the angle which it makes with the fissure of Sylvius, turns round the end of this and ends in a group of vertical flexures, which anastomose, sometimes with the first, sometimes with the second temporo-sphenoidal convolution, and sometimes with both. This is the inferior parietal convolution, or curved fold of Gratiolet (10), so called because the fold embraces in a simple or complex gyrus, not only the termination of the fissure of Sylvius, but also that of the parallel sulcus. Another arrangement is found. The termiaation of this parallel sulcus is bifurcated, and its posterior branch reaches the external perpendicular fissure, which it leaps over to become one of the transverse sulci of the occipital lobe. In this case, the gyrus which the curved fold forms is persistent ; but it goes to form what we shall presently caU the second transition convolution, without anastomosing with the second temporo-sphenoidal convolution. M. Gratiolet has described on the side of the inferior parietal convolution, a superior marginal fold, and an inferior marginal fold, which are merely the folds bordering the extremity of the fissure of Sylvius. The former, indeed, is the part of the inferior parietal convolution, which extends from its junction with the posterior ascending convolution, to the end of the fissure, and the latter is the continuation of the first temporo- sphenoidal convolution. The increased size of the flexures is of httle importance, inasmuch as they constantly vary. The occipital lobe, the smallest of aU, is formed of three storeys which are bounded by two antero-posterior sulci. The external Chap, hi.] INTERNAL SURFACE OF HEMISPHERES. Ill perpendicular fissure separates it from tlie parietal lote, and from the temporo-sphenoidal lobe ; a fissure somewhat difiicult to trate out in Man, because it is partly filled up, or hidden "by four folds of communication with the adjoining lobes, whose study affords considerable interest under the name of plis de passage, or transition convolutions (a, b, c, and d). The first, or superior, of Gratiolet, comes from the superior parietal convolution; the second, or in- ferior, from the inferior parietal ; the third, lower down, from the second temporo-sphenoidal convolution ; and the fourth, concealed at the inferior border of the brain by the third temporo-sphenoidal convolution. We shall say but little as to the internal surface of the hemi- sphere, which is in apposition with the falx cerebri on the median line (Fig. 17). When we harden and dry a brain by M. Broca's process (nitric acid),* the organ shrinks more in the transverse direction, and that which formed the concave part of the interior surface behind, appears, when looking at it sideways, to form part of the internal surface. We shall study in this way the two surfaces united. In the centre is seen the coipus callosum, an elongated vault which covers in the ventricles, and is terminated in front by a swelling called genou (knee), the most slanting point of which is the hee (beak), and behind by another swelling called the hourrelet (cushion). Towards its exterior extremity is then seen a slit rendered gaping by the preparation, which is the internal perpen- dicular fissure already described. On this surface is a triangular lobule, forming a portion of the occipital lobe, looking from this side, and which bounds the sulcus of the hippocampi below. All the portion situated beneath, and to the left of this sulcus in the figure, is the internal surface (at the lower part) of the temporo- sphenoidal lobe. A primary and well-defined transverse sulcus, and a smaller faint one which is parallel to it, divide this region into three convolutions (6, 7, and 8) ; the superior bending round * "Precede pour la Momifioatiou des Oerveaux," by M.

This lobule is formed by the junction, looking from the internal surface, of the two anterior and posterior ascending convolutions of its external surface. The remaining portion of the internal surface is divided into two parts, the one superior and anterior, which forms part of the frontal Chap, hi.] CONVOLUTIONS. 113 lo"be; the other inferior, and resting on the corpus callosum, to which we must consider it as attached. A fissure, however, divides them, which is called festonn&e, or calloso-marginal, ia its anterior four-fifths, and fronto-parietal towards its termination. It com- mences below the beak of the corpus callosum, turns round its knee, passes horizontally behind, and, separating the oval from the quad- rilateral lobule, reaches obliquely the superior border of the hemi- sphere. A single convolution, called the convolution of the corpus callosum, is concentric to it, and contiuues to follow this organ, to form the base of the quadrilateral lobule, and to anastomose with the first internal temporo-sphenoidal convolution. Another convolution, called the iatemal frontal, is eccentric to it, and has the form of an italic S. Its anterior gyrus is separated from the knee of the corpus callosum by the convolution and the fissure just mentioned, and its posterior gyrus forms the oval lobule. In the greater part of its length it is divided by an interrupted sulcus into two storeys, of which the first is in direct contiuuation with the first frontal convolution on the external surface.

[Chap. hi. selected individuals. Simple convolutions, developed uninter- ruptedly, and alike in both hemisplieres, are characteristic of inferiority hi Man, as well as throughout the mammalian series. Bichat then was wrong when, influenced by a statement of Tiedemann, he attributed intelleotual aberrations to the asymmetry of the brain ; his own autopsy proved the contrary.* The difference between the encephalon of mammalia and that of Man is in the relative volume of the principal parts, in certain internal structural arrangements, in the absence or in the number of the convolutions, and in the weight of the organ. On viewing the whole encephalic system on its superior surface, we notice that the hemispheres in the marsupialia and monotremata exhibit in front certain swellings called oKactory bulbs, which, in the majority of mammalia, have the importance of lobes, and behind the greater portion of the tubercula quadrigemina, or optic lobes, and the cerebellum. In other animals, as the ant-eater, the rat, the hare, and the bat, the optic lobes cease to be visible, but the olfactory lobes and the cerebellum are more exposed to view. In others, and as far as monkeys exclusively, the former are concealed, while a more or less considerable portion of the cerebellum is visible. In lemurians, the cerebellum slightly projects beyond the hemispheres ; in pithecians and cebians it is more generally on a level with them. In the anthropoid apes and in Man, not only is it out of sight, but the hemispheres in their turn more or less pass beyond it. * On the subject of the convolutions, see " Traite de I'Anatomie Physiolo- gique et Pathologique du Syateme Nervens CeriSbro-Spinal," by Foville, lafc part, Paris, 1844 ; " Memoire sur les Plis du.

Chap, hi.] DIVISIONS OF OWEN. 115 The brain is modified also as to form. In Man it is more or less elongated as a whole, and ovoid at its anterior extremity ; its frontal region is contracted occasionally, as though squeezed together, globular, and acquires its maximum of fulness. The last traces of this contraction are seen in front, at the poiat of the internal anterior and inferior angle of each hemisphere. It is more or less strongly marked in pithecians, less so ia the anthropoid apes, and com in only not at all in Man. In these two relations, the anthropoids more nearly approach to Man than to the other monkeys. As regards iuternal structure, the first difference is the absence of the corpus caUosum in the marsupiaUa and the monotremata, ■as well as in the classes of vertebrata below, whilst it exists in aU the other mammalia. The aqueduct of Sylvius, a simple canal perforating the corpora-quadrigemina in. Man and the majority of the mammalia, is a cavity, or rather a supplementary ventricle in the kangaroo. The anterior and middle comua of the lateral ventricles exist in aU the mammalia ; the posterior or occipital comu is peculiar to Man, to the monkey, the seal, and the porpoise. Professor Owen thought that the absence in anthropoids of this comu, of the hippocampus minor belonging to it, and of the -occipital lobe in which it is hoUowed, constituted a distinct cha- Tacteristic separating the ape from Man. On more careful examina- tion, however, he altered his opinion. Man and the anthropoid ape in this respect' are alike. A characteristic of Man has also been sought for in the pre- sence of the mammillary tubercles, little round bodies situated at the base of the brain, and whose use is unknown. "Vain hope ! The chimpanzee, the orang, the gibbon, and. the mdne possess them. The convolutions are wanting in fishes, reptiles, and birds. They are absent in a considerable number of mammalia, are tolerably developed in others, and very much so in many, as the porpoise and the elephant. Mr. Owen has proposed to make them the basis of a fourfold classification: (1) Lyencephala, having the brain ismooth and the optic lobes exposed ; (2) Lissencephala, having the I 2 116 CONVOLUTIONS IN MAMMALIA. [Chap. hi. brain smootli, but with tlie optic lobes concealed ; (3) Gyren- cephala, witb but few convolutions; and (4) Archencephala, in wbicb Man alone is placed. But tbe other features of the organisa- tion do not move in parallelism with these characteristics, and the fourth class is only hypothetical.* Erasistratus of old wrote that the convolutions are more numerous in Man, because he is supreme as the possessor of a mind and reasoning power. A. Desmoulins, in 1825, maintained that the number and perfection of the intellectual faculties in species as in individuals, are in proportion to the extent of surface of the hemi- spheres, and that this is in direct ratio to the number and depth of the convolutions. M. Dareste started another proposition : that the convolutions were developed in a direct ratio to the stature, and that the smaller species most frequently have the brain smooth. Gratiolet took upon himself to refute him. Man, and then the orang, the chimpanzee, the seal, the bear, the dog, the elephant, have the most complex convolutions ; whilst in the insectivora, the rodents, and the marsupials, generally less intelligent, they are scarcely visible. Neither the stature nor the volume of the body has anything to do with the question ; the smallest dog has more convolutions than the most gigantic kangaroo, the seal more than the ox. There are eKceptions, but these are easily explained. The increased amount of the gray cortical substance of the hemispheres is what we must look for as evidence of a larger amount of activity. "We must look for (1) The increase of the cerebral mass, and consequently, cmteris paribus, of its surface ; (2) The increase of the number of folds and windings, which allow of a much greater proportion of the gray substance being deposited in a given space; (3) The increase of the latter in thickness, and its improvement in quality. Unless we take account of aU these elements we must not be surprised if there are exceptions, but the general fact remains — the amount of intelligence in mammalia is in proportion to the development of the convolutions. The consideration of the monkey tribe will now eno-ace our * "The Anatomy of Vertebrates," vol. iii., "Mammals," by R. Owen. London, 1868. Chap, hi.] SIMIAN VARIATIONS. 117 attention. From tlie ouistiti, the lowest of the cetians, which has the brain smooth and only a trace of the fissure of Sylvius, to Man, every variety is to he met with. In the sagouins, some convolu- tions are visible. Their number increases rapidly in the highest cebians and the pithecians. In anthropoids, suddenly and almost without transition, they have a similar appearance to those of Man. All the principal convolutions are there, the type is the same, the difference is only in parts of a subordinate character, and in the de- gree of convolutions, which varies also in Man and is peculiar to him.

These primary convolutions, these essential parts, common and only common to all human brains, are 118 SIMIAK VAEIATIONS. [Chap. hi. foimd without exception in the braias of the orang and the chim- panzee." That of the gorilla is hut little known.* A few words as to the changes which are exhihited as far as the inferior orders of cehians. The orhital region of the frontal lohe, which is flat in Man, is depressed in pithecians ; the sulcus of the olfactory nerve is want- ing; the angle which termiuates the third frontal convolution hehiad is rectUinear, which has tuterest with regard to the faculty of language. The iirst frontal convolution is simple, as in the Hottentot Venus of Cuvier, and the idiot studied by Gratiolet, while it is double in the orang and the chimpanzee, as in Man. The inferior parietal convolution should rather be called the curved fold, as it commences more in front and more distinctly curves round the terminations of the fissure of Sylvius and the parallel sulcus. The superior parietal convolution is very much reduced, particularly in the cynocephali. In the chimpanzee it forms a lobule as important as in Man. The external part of the perpen- dicular fissure is more open and more visible by the absence or the greater depth of the pUs de passage of this region. It follows that the occipital lobe throws up above it at its upper part an oper- culum, whose amount of projection is less characteristic of inferiority. The central lobule, very smooth in Man, slightly so in the orang and chimpanzee, is smooth in the majority of pithe- cians and cebians, and is wanting in lemurs, as also in the other mammalia. The occipital lobe deserves especial notice. Its volume is generally in an inverse ratio to the number of the sulci and convo- lutions. Almost entirely smooth in cynocephali, its uniform sur- face contrasts so strongly with the rest of the cerebral surface in the macacque and the guenon, that Gratiolet compared it to a cap covering the posterior extremity of the brain. The contrast is less in some semnopitheci ; some gashes are seen, which are well marked in the gibbon, and become in the chimpanzees and the orang very nearly as complex as in Man. * Memoir already quoted, " Snr les Primates." Chap, hi.] PLIS DB PASSAGE. 119 Owen discovered a cerebral characteristic of Man in the structure of his occipital lobe ; Gratiolet, in his second pK de passage, from the parietal to the occipital lobe. It is not a question of two iuf erior plis de passage, they always exist. Thinner in gibbons and pithecians, they are thick ia Man and the great anthropoid apes, and entirely fill up the inferior (or external) portion of the external perpendicular fissure. It is otherwise as regards the two superior ^Zm de passage. They are superficial, deep, or altogether wanting, according to four types. (1) In Man and the ateles — the highest in the order of cebians — they are both superficial, hence the difficulty that students have in discovering the external perpendicular fissure which they traverse. (2) The first is super- ficial and the second deep in the orang, the gibbon, and the senmo- pitheci. (3) The first is wanting and the second is deep in the chimpanzee, the macaque, and the cynocephalus (the goriUa has not been studied in this respect). (4) Both are deep in the guenons. The three anthropoid apes which have been studied differ, then, from Man, in that the second fold is deep. There is some doubt as to the first fold being absent in the chimpanzee ; it was present in. the subjects studied by Eolleston, Marshall, and Turner. Ifotably, in two, the first fold was present on one side and not- on the other ;■ while, by way of compensation, the second was deep on one side but superficial on the other : according to M. Broca it should always exist on one side or the other. Moreover, in Man, even in individuals of sound mind, one of the sa^enoi plis de passage may be deep on one side or wanting, and the other at the same time be feebly developed. Does not all this prove that these are only changes or gradations of development from the healthy man to the anthropoids, the cebians, and the pithecians 1 Eelative to anthro^ poids we can only come to one conclusion, namely, that they are not more separated from Man by the character of their plis de pas- sage than from the monkeys next in order, and that in this, as well as in everything relating to the convolutions, they are found to take their place with Man at the head of the series. If the differences hitherto established in the morphology and anatomy of the brain of Man, as compared with that of animals, are 120 WEIGHT OF THE BRAIN. [Ciup. in. not such as we should have desired, what avo arci about to say with respect to its weight and mass, and what we have ah'eady said on the subject of the cranial capacity, will be sulliciont to satisfy the warmest advocates of human supremacy. The weight of the oucephalon varies in the adult man of sound mind from 1,830 grammes, which was the wniglit of Cuviuv's brain, to 872, which is that of a Bosjeswonian studied in England by Mr. Marshall : but these are exceptional cases. According to Huschke, its mean weight, at the age of 30 or 40 years, in tho white race, and when the organ has attained its full growth, is about 1,410 in men, and 1,272 in women. The weight varies, moreover, according to height, sex, age, intelligence, and occupa- tion. Let us rapidly run over the principal results obtained on these points, in order that we may not have again to recur to them.* The encephalon is heavier in taU persons than in short. In five men having a mean stature of 1'74 mfetre, the brain was 96 grammes heavier than in five other short men, whose mean stature was r63 m^tre. Tho diiference of weight was 6 per cent., and corresponded exactly with the difl'erence of stature. The same result has been obtained in reference to women. The brain is lighter in the woman than in the man : tho former weighing 100, cceteris paribus, the latter would weigh 111!, accord- ing to Huschke. This difference is only attributable tn tho fact Uiat usually she is less in height. I'archappo has shown that the height of the woman is to that of the nmn as 92'7 to 100; whilst the weight of her brain would be as 90-9 to 100. Tho brain, then, is lighter in the woman, and we may add, that it is so at all ages. The tables constructed by Broca, with materials furnished by * " Sur le Poids da Oerreau," by L(51ut, in " Journal dos Conn. Mddioo.

III.] WEIGHT OF THE BRAIN. 121 Wagner, of the weiglit of 347 healthy brains, prove that this organ goes on increasing up to 40 years of age, that it remains stationary up to 50, and decreases afterwards. After the age of 60 years men had lost from 5 to 7 per cent, of maximum weight, and women from 4 to 7. Gratiolet has shown that the cranium of the infant is more elongated at birth, that it enlarges subsequently in the temporal regions, and that it goes on developing in front : it ought to be the same with the brain. The brain increases, eceteris paribus, in proportion to the vas- cular activity of which it is the seat. This is the reason that the brain of certain criminals and lunatics is so large. But of all the kinds of activity, that which has reference to the special design of the organ has the most influence. Such is physiological activity, of which intelligence is the result. The weights taken by L^lut, Parchappe, and Wagner, clearly show this. The labouring men studied by Parchappe had the head longer than his " distinguished men." So with the internes of the hospital of Bicetre measured by M. Broca, relatively to the officers of the institution. The cranial •capacity of Parisians from the twelfth to the nineteenth century, has increased to such an extent that we may be allowed to attribute it to the progress of civilisation. The cranial capacity is greater, eceteris paribus, in the white race, less generally in the negro races, less still in the lowest among them. The brains of idiots, and of the insane in lunatic asylums, are smaller and hghter than those of the employes and ordinary sick, or of persons suffering from acute mania. The enormous weight of Cuvier's brain is in itself an argument. 'So less remarkable, though less largely developed, were the brains of Abercrombie, of Bruce, of Dupuytren, and other eminent persons, as recorded by Wagner. The reason that the brain of the woman is Hghter than that of the man is that she has less cerebral activity to exercise in her sphere of duty. In former times it was relatively larger in the department of Loz^re, because there the woman and the man mutually shared the burden of their daily labour. The truth is, that the weight of the brain increases with the use which vve make of that organ, with the exercise of certaia professions ; in a. word, with the degree of intelligence. The absolute mean weight 122 EELATIVE "WJilGHT OF THE BRAIN. [Chap. m. of the 1)13111 at its maximum of growth, in men, is, in round numbers, about 1,400 grammes, in. women about 1,250. With some few exceptions it is the heaviest of the mammalian series* We will give the figures farther on. They would, however, be of little value as regards the majority of mammalia if we did not take account of the stature or weight of the body. M. Sappey estimates the weight of the braiu of the elephant to be from 1,500 to 1,600 grammes, and that of the dolphin about 1,800; and then it would be in proportion to the weight of the body as 1 to 1,500 in the former, and 1 to 100 in the latter; while in Man it is as 1 to 36, ac- cording to Cuvier, and 1 to 52 according to Colin. This may be so, but we do not think these figures are to be thoroughly relied on ; for the brain of a young Asiatic elephant in M. Broca's laboratory weighed double, that is to say, 3,080 grammes; the greater reason why we should take into our calculation the stature of the animal. In the list published by Cuvier, the weight of the brain being 1, that of the body is from 48 to 105 in the ordinary monkeys ; from 97 to 365 in the camivora ; from 520 to 800 m marsupials ; from 750 to 800 in two oxen. In a gibbon, according to M. Leuret,* it was 48, and in another, in M. Broca's laboratory,. 18 '7. Most fortunately, we are able to make a direct comparison between Man and the three higher anthropoids. If, on the average, they are a little less in stature, they are, on the other hand, stouter, so that the body, taken as a whole, agrees as nearly as possible. The anthropoid is generally a little more bulky, which, cmteris paribus, would necessitate his having rather a larger brain. It is true that we have not had an opportunity of weighing the brains of the great apes in a fresh state, but we may estimate the weight sufficiently accurately by the cranial capacity, f Mr. Huxley thinks that the weight of the brain of the gorilla may reach 567 grammes, and M. Broca found that the weight of the one the cubic measure- * See " Anatomy of the Nervous System," by Iienret, vol. i., 1839, and the table at page 124. •|- Mr. Owen, however, weighed the fresh brain of a gorilla : it was 15 onnoea = 425-19 grammes.

Proportions of different Parts of the Eneephalon. M. BaiUarger has attempted to estimate the absolute extent of surface of the convolutions which is covered hy the gray substance. He found it to he 1,700 square centimetres ia Man, and 24 ia the rabbit. M. Hermann Wagner calculated the amount of superficies in each lobe relatively to the total superficies of the brain. It is to be feared that the result of these efibrts has not been of much im- portance, though they should be encouraged. The following are the mean proportions obtained by M. Wagner : Man. Orang.

The weight of the former in the man is about 179 grammes, and in the woman 147 grammes, according to Par- chappe, and 176 in Man, according to Lflut. This weight being expressed by 1, that of the hemispheres would be 15 '5 in the man, and 13 '9 grammes in the woman, according to Paichappe, and 15 '5 also in the man, according to Lflut. It is the same with animals : in the saimiri it is 14 j m6ne, 8 ; magot, papion, and coita, 7 ; ouistiti, 6-3; macauco, 4 '5; gibbon, 4 '4 grammes, among apes: and the hedgehog, 12 j hare, 14 '3; ox, 9; horse, 7 j sheep, 5; mouse, 2, among the mammalia (Leuret). It foUows from this that the human cerebellum is Kghter in proportion to the weight of the brain, and if we put aside three of the 44 examples of Leuret, that Man would be found to have the advantage in this respect, as 124 PROPORTION OF THE CEREBELLUM.

CoUn's conclusions deserves to be considered side by- side with that arrived at by M. Dareste. He says the smaller species of animals have the braia more developed than the larger. The mouse, for example, has, in proportion to his body, more brain than Man, and thirteen times more than the horse, and eleven times more than the elephant. M. Dareste infers that the smaller species generally have the brain smooth. The two propositions mutually agree. The convolutions have less tendency to be developed ia the smaller species, supposing the fact proved : because their braia is larger, this was superfluous. Thus the same result is arrived at by different methods of proceeding. Lastly, Soemmering has conceived the idea of comparing the brain with the nerves which proceed from it. The relative volume of the former would be considerably greater in Man; the apes would come next. " The largest horse's brain that I have weighed," says he, " was one pound and seven ounces, and the smallest man's, two pounds five ounces and a quarter, notwithstanding that the nerves at the base were ten times larger in the former, although the difference in weight between the two brains was at least fourteen ounces and a quarter." Chap, hi.] MEASTJEEMENT OE THE BRAIN. 125 Measurement of the Brain. This has iiot yet been practised to any extent except on animals. Soemmering and Ebel have compared the width of the medulla oblongata, at its union with the protuberantia annidaris, with the maximum width of the brain. Leuret has taken the relative dimensions and situation of the corpus callosum and the cerebellum. Cuvier has given the width, the height, and the maximum length of the brain in 38 mammals. Leuret applied himself to the width in relation to the length, taking his measiu'ements, not on the brain, but on the interior of the cranial cavity. We can speak highly of this method, when we employ the special instruments invented by M. Eroca, which allow of all the details being measured without injuring the skull by making a section. In a first group, including the kangaroo, the guinea-pig, and the beaver, the two diameters are equal ; in a second, consisting of the majority of the rodents, the elephant, the porpoise, and the whale, the trans- verse diameter is greater than the antero-posterior ; in a third, embracing the monkey tribe, the carnivora, the solipeds, and the ruminants, the antero-posterior diameter is the longer, as in Man. The relation of these two diameters, the transverse and the antero-posterior, is worthy, in our opinion, to have a place assigned to it in Zoological Anthropology, under the name of cerebral index. A few calculations from Leuret's tables are subjoined.

Rudimentary Organs and Reverdve Anomalies. In the necessarily rapid examination which we have just made of the characters by which Man differs from or approaches to animals, we have only taken iato consideration those which are constant and exist in aU individuals. But there are others which unexpectedly make their appearance in aU the races of Man, and more frequently in those reputed inferior, concerning which we ought to say a few words. "We refer to what are called the rudimen- tary organs, and anomalies. In the hypothesis of a transformation by a certain process from forms relatively inferior into those of a higher and m.ore perfect character, they take the name of reversions, which is meant to convey the idea of a relationship in the past between organisms now divergent, and bearing upon the question of the af&nity of Man with the other mammalia. As examples of rudimentary organs in animals we may mention the germs of teeth in the foetus of the whale, and those of the upper incisors in ruminants, although these organs are never developed, and appear to be useless ; the teats of all male quadrupeds ; the eyes of sightless animals, or those species which pass their lives in dark caverns, or inhabit the fathomless depths of the ocean ; the two needle-like ossicles on the sides of the single metacarpal or metatarsal bone of the horse, which represent the other meta- carpals or metatarsals which have disappeared ; &c. Examples are numerous in Man. The semUunar fold at the internal angle of the eye, so marked in some persons, would repre- sent the remains of the third eyelid of marsupials, the walrus, &c. ■Chap, hi.] REYEESrVE ANOMALIES. 12V Tte vermicular appendix of the large intestiae, whicli seems useless, and is occasionally the cause of death, is the representative of an organ which is enormous in herbivorous animals, and in the koala attains a length three times that of the hody. The muscles of the ear, equally useless, although sufficiently developed in some indi- viduals to enable them to move the cartilage, are merely vestiges of a very •well-marked apparatus in animals. The sub-vomerian bone of Eambaud, in like manner, is the remains of the organ of Jacobson, and is very much developed in the horse, as also in some apes, &e. Anomalies are still more frequent in Man. We may mention the bifid, and even the double uterus ; the former repeating the homed uterus of the rodent, or the elongated and angular uterus seen in some ordinary monkeys and lemurs ; the latter the double uterus with two orifices of marsupials. We may mention the per- sistence in the adult of the suture which divides the malar bones into two, as in some apes and other mammaha ; that of the median frontal suture, as in the majority of the lower mammalia ; the ap- pearance, once in a hundred times, according to Mr. Turner, of the super-condylean humeral foramen peculiar to various animals, through which the principal nerve and artery of the limb pass ; the altogether simian conformation of the cartilage of the ear ; &c. In the muscles especially reversions are common. Traces of the cutaneous muscle are seen in the armpits and on the scapulse, as well as on the head and face ; the sternal muscle of mammaha was seen in 18 out of 600 men; the ischio-pubic muscle, > constant in the majority of male animals, was noticed in 19 out of 40 men, and in 2 out of 30 women ; the elevator claviculse of most apes in 1 out of 60. M. Chadzinski, in the " Eevue d'Anthropologie," has given many examples of simian arrangements in Man. Mr. J. Wood found in one individual as many as seven examples of muscles pecuhar to certain apes. Whatever interpretation may be given to these facts, they estab- lish a link between the type of organisation of Man and that of animals. A third order of facts has been brought together, namely, those which we term teratological, and of which we shall speak by- and-by. 128 DEVELOPMENT OP THE BODY. [Chap. it. CHAPTER IV.

Hitherto we have been engaged ■with anatomical characters, that is to say, with those relating to the organs as seen after death. We shall now consider the physiological, or those exhihited in the living subject, the result of the growth and development of those organs. Their history commences from the period when the first lineaments of organisation were planned, continues through the various phases of existence, and exhibits to us Man moving and thinking, up to the period when motion and thought cease. Development — A ge. Our first entrance into life is unostentatious, and in no way differs from that of animals. Enclosed in an ovum of the same character as that of all the oviparous or viviparous mammalia, nothing then distinguishes the future monarch from the humblest pariah— the lord of creation from the ape or the kangaroo. The researches of WoM in 1759, of Oken in 1806, of Baer in 1819, of Coste, &c., have put this beyond contradiction. The ovum at first is a simple cell, a microscopic point, which is composed of an albuminous substance, or vitellus, and of a nucleus, or germinal vesicle, enclosing within it a nucleolus, or germinal spot. Under this form it is throvm off from the ovaries, traverses the oviduct, passes into the uterus, and, if it becomes fecundated, is there developed. The cell then becomes divided into two, into four, and gradually into an infinite number of cells, which increase at the periphery and assume the form of a hollow sphere. At one Chap. iv.J DEVELOPMENT OF THE BODY. J 29 point there afterwards appears an opacity, whiclL becomes elongated and divided into three leaflets. This is the rudiment of the future being, whether man or dog. The external leaflet wiU become the skin and cerebro-spinal axis, the internal the digestive mucous membrane, the middle the parenchyma from which the various organs are formed. The multiplication of cells continuing, a primitive line is drawn, which has at one of its extremities an en- largement, upon which before long are seen five ampullse. The line is the spinal cord, the enlargement is the brain, the anterior ampidla will be the hemispheres, the second the optic thalamus, the third the tubercida quadrigemina, the fourth the cerebellum, and the fifth the medulla oblongata. According to the variable development of these rudiments, results, by degrees, the special genus or species. At the fourth week the difference between the Man and the dog is inappreciable. The divergence only commences in earnest at the eighth week. In the human foetus the anterior ampulla becomes larger, in the foetus of the dog the caudal extremity elongates. At birth the infant weighs from 3 to 4 kilogrammes, and is 50 centimtoes .in length; his pulse is 140 in the minute; a fine down covers his body; his pupils are generally open as soon as respiration becomes fully established ; the thymus gland, an organ exclusively foetal, atrophies. He takes the breast up to the second or third year, or rather until the sixteen or twenty m\U]r teeth have appeared. During the period of infancy the pulsfr ranges from 100 to 110, the respiration becomes propor- tionately slower, its movements being in relation to the heart's pulsations as 1 to 3. At about 14 years, in our climates, puberty takes place in the boy ; his features become altered, the voice changes, the beard developes, and most important modifications take place in the genital organs. At the same time, in the girl, the breasts increase in size, the menses make their appearance. At 20 years adult age is attained ; growth still goes on ; the brain continues to be developed in proportion to its exercise, and attains its maximum of activity at or before 35 years. Soon decadence commences ; the faculty oi reproduction in the man becomes diminished. In womau K ISO GROWTH OF THE BRAIN. [Chap. it. the hair turns white and falls off ; the teeth hecome loosened from their sockets ; the crjstaUine lens is flattened, causing the eye to become presbyopic ; the senses become dull ; the lung is emphy- sematous, the heart hypertrophied j the arteries become ossified; fat is infiltrated through the tissues, and death takes place naturally, ■without any struggle, from the moment that one of the three prin- cipal organs of organic life — the heart, the lung, or the digestive tube — loses the power to perform its function.* Except ia some trifling particulars, this is the same as regards all mammalia. The organisation of Man, of the anthropoid ape, or of the carnivora, obeys the same physiological laws, and passes through three similar periods : one of growth, one of full development — during which the process of reproduction goes on — and one of decay. These periods are of longer or shorter duration — that is the only difference. Of all these phenomena, those which are exhibited on the skeleton have the greatest amount of interest for the anthro- pologist. It is by a thorough acquaintance with them that we determine with accuracy the age of bones, a problem not less im- portant for the anthropologist in his laboratory than for the archseologist who is desirous of ascertaining the date of his fossils. A few words, however, as to the head. Its proportions relatively to the body during the earliest periods of embryonic existence, or even at birth, are not what they are at a later period. At the second month of intra-uterine life the head forms one-haK, at birth one-quarter, and at adult age one-eighth part of the entire body. The same may be said as regards the contents of the brain- case. Qrowfh of the Brain. Throughout the whole of the mammalian series this organ is * M. Brooa dividea the periods of Imman life as follows : First infancy from birth, to the end of the sixth year, when the first large permanent molar is cut ; second infancy, from 7 to 14 years, on the eruption of the second molars ; youth, from 14 to 25 years, when the basilar suture is ossified, or the wisdom tooth is out ; adult age, from 25 to 40, when the cerebral sutures begin to ossify ; ripe age, from 40 to 60 ; old age, beyond 60 years. In oraniomrtry, we designate, in a general way, under the name of adult, crania in which the basilar suture is closed. Chap, it.] OSSIFICATION OF THE CEANIAL SUTURES. 131 smaller relatively to the rest of the body at hirth than at the period of its complete development. In the newly-born marsupial, Mr. Owen says it is less large in proportion than in the upper classes of mammalia. The following figures of M. Welcker exhibit the cranial capacity in Man at different ages, and conser[uently the progressive volume of his brain : Men. Women. Centimfetres. Centimetres New-bom infant ... 400 ... ... 360 At 2 months ... 540 ... ... 610 At 1 yeax ... 900 ... ... 850 At 3 years ... 1080 ... ... 1010 At 10 years ... 1360 ... ... 1250 From 20 to 60 years ... ... 1450 ... ... 1300 In anthropoids the development is less rapid : we are ignorant as to their cranial capacity at birth, but during the first dentition, in eight orangs, it was found to be 322 cubic centimfetres, while ia 15 adults of the same species it was 413. Supposing, then, that their first dentition takes place at the mean age of two years, the cranial capacity would iacrease 31 per cent, in Man from this period to adult age, and 22 per cent, only iu the orang. To obviate the numerous disorders to which so considerable a •development of the brain would give rise, owing to the resistance •of the walls of the cranium, the sutures which unite the bones preserve their softness a much longer time in Man, and do not begin to ossify until a late period, when there is no longer any probability of the iucrease of the contents, and when cerebral acti-dty is becoming less. This leads us to speak of the action of the sutures, and of the chief means of ascertairiing the age of a cranium. Ossification of the Cranial Sutures. The bones pass through three phases, corresponding to the three periods of life. In the first, the bone is soft, then cartilaginous ; m the second, it is osseous, and continues so in every part ; in the K 2 132 OSSIFICATION OF THE CBA:ffIAL SUTURES [Chap. it. tHrd, or senile period, it becomes more dense, although lighter and more fragile, the diploe in the flat bones is more spongy, the medullary canal in the long bones is of greater diameter, and the ceUs at their extremities are larger. Between the first and second period there is one of transition, during which points or centres of ossification appear in the middle of the cartilage, which gradually become larger and larger, and at last occupy the entire bone. These points are of two descriptions — ^the principal ones for the body, or diaphysis ; the secondary for the extremities, or epiphyses, and the prominences or processes. In the skuU, the points of ossification first appear in the centres which correspond with the bodies of the three cranial vertebrae — the basilar process of the occipital, the posterior sphenoid and the anterior sphenoid, then in the lateral bones and in those of the- vault. It is well to know the period at which the secondary portions become united, so as to be enabled to judge, in certain circumstances, if the development has proceeded regularly. Thus : At the third month of foetal life the two superior points of the occipital shell become united to the two inferior. "What we caU the interparietal suture is closed. At the eighth or ninth month of foetal Kfe the body of the anterior sphenoid is united to the body of the posterior sphenoid. About two months after birth, the false suture which separates the basilar portion of the occipital from the two condylean portions is closed. About the fifth or sixth months the body of the posterior- sphenoid is united to the greater wings. About a year, the three portions of the temporal — ^the petrous,, the mastoid, and the squamous — beeome anchylosed. The two^ halves cif the frontal also. The suture which they form whem they are persistent in the adult, is called the medio-frontal, or- metopic. We have noticed this abnormal persistence in 58 out of 611 Parisian skulls which we Jiave examined = 1 in 9-65. About the third or fourth year, the styloid process becomes united to the temporal, unless it continues separated from it during, the remainder of life. Chap, it.] OSSIFICATION OF THE CRANIAL SUTURES. 133 About tlie fifth or sixth year, the suture which separates the external occipital portion of the occipital sheU is closed. The true sutures are the coronal, the sagittal, the lamhdoidal, the temporal, and the spheno-parietal, spaces heing formed at their junction, which are designated hy the name of fontaneUes. The exact period at which the process of ossification is completed at theii edges is douhtful. The sagittal and coronal sutures close ¥ery soon after hirth, and before those of the base. The bregmatic fontanelle, except in cases of disease, is always closed before two- and-a-haM years of age according to M. Bouvier, and sooner according to M. Broea. The suture which unites the occipital to the sphenoid is sometimes wanting in animals, sometimes it remains persistent through the whole of life : in Man it passes immediately from the oaxtUaginous to the osseous state at from 18 to 22 years of age. All these data serve to determine the age, but it is at their third phase, when other parts of the body fail to give us any information, that the examination of the sutures becomes valuable. At this moment the serratures become obliterated, the bones which are in contact become anchylosed, the suture is synostosed. This synostosis, one of the first signs of age in the skeleton, may in some cases be produced more quickly by disease. There is, then, no adult or stationary condition of the suture, and the younger the individual the more serious the disorders which result from it as regards the development of the cranium and the brain. We shall consider this subject further when speaking as to pathological characters. The spot where synostosis first appears during the progress of age varies. The most frequent is at a point on the sagittal, at the union of its posterior fifth with its anterior three- fifths, where the suture is clearly marked, oMlion. At other times it is at the extremities of the coronal> near the temporal ridge, or lower down, at the junction of the four sutures, in the form of the letter H. The second or third spot is on the lambdoidal suture, the synostosis appearing at first in the middle of one of its branches, or as an extension of the sagittal ossification. The fourth 134 OSSIFICATION OF THE CRANIAL SUTURES. [Chap. it. point is the coronal suture, close to the bregma. The fifth is on the squamous suture of the temporal.* In a word, if the suture is entire, the indiridual is about 35 years of age or less. If the posterior sagittal point is commencing to close he is about 40 years. The ossification of the coronal suture close to the bregma would show that he was 50 or more. If the temporal suture is closed he would be 66 or more. As regards intermediate and subsequent ages we examine as to the extent to which complete closure has taken place at each spot, and also as to other matters, of which we are about to speak. The definite period of ossification of the sutures moreover varies very considerably. It sometimes takes place partially and very early in life ; at others it is retarded. The more the brain is exercised the more it is postponed, according to M. Broca. In idiots it takes place early. It varies according to race. In the white races the ossification generally proceeds from behind for- wards. In the negro races it is the reverse, according to Gratiolet, that is to say from before backwards. This latter statement is somewhat hasty ; and without going so far as to deny it, we should say it cannot be looked upon as universally the case. If the brain-case at the period of birth is very large, the face, on the other hand, is small, and makes increase, especially in the maxillary region, as is shown by the enlargement of the facial angle and of the angle of prothagnism, from infancy to adult age. The development for the most part takes place in the alveolar arches, at the part corresponding with the molars of the second dentition ; they become elongated from behind forwards, and increase in height and thickness. A phenomenon the reverse of this takes place when the teeth fall out naturally in the progress of age ; the edges of the alveoU come nearer together and become absorbed, and the alveolar border loses its height and thickness. Two anatomical results are the consequence : (1) The mental foramen, situated in the adult at an * See "Reoherohes box I'l^tat Senile du Crane," by E. Sauvage. Paris, 1870. Chap, iv.] EVOLUTION OF THE TEETH. 135 equal distance from, or a little nearer to, the two borders of the hone, appears ia the old man gradually to come nearer to the superior, a circumstance of which M. Broca has taken particular notice ia his interesting memoir, published ia 1848, on the bones of Celestines. (2) The angle which the horizontal makes with the posterior branch of the lower jaw becomes widened, and has a tendency to return to that which it was in iafancy. This angle at birth is from 170 to 160 degrees; it descends to 150 and 130 during the first dentition; then to 115 degrees duriag the second dentition ; approaches a right angle during the adult period, and returns to 130 and 140 degrees ia old age {Humphry). Thence a series of characteristics which, even in solitary maxillse, enables us to ascertain approximately the age of the individual. Besides those furnished by the cranial sutures, there are others drawn from the ebumification, or the unequal atrophy of the malformed cranium, as weU as those from the teeth : aU appearances on the head, so probably indicative of the same fact as regards age, as to be looked upon as certaiaties. The maxillary apparatus is not the only portion of the face which assumes various alterations of phase during life. The brain cavities do the same in a less degree. Thus the frontal siauses connected "vvith the olfactory apparatus are rudimentary in the infant, very largely developed in the adult, and become atrophied ia old age. All the siauses of the face, moreover, iacludiag the mastoid cells, obey the same law — they do not arrive at their full development untU after puberty. Evolution of the Teeth. Of aU the methods ia use for the purpose of determining the age of a cranium, particularly before the adult period, those derived from the examination of the teeth are the most satisfactory. Their evolution is divided iato two periods, the more important to define, in that we have no other data from which to form an idea as to the relative age of the monkeys imported into Europe. The duration of the first period in Man is about 24 months, when the whole of the milk or temporary teeth are cut; that of the second ia sis 136 ERUPTION OF THE TEETH. [Chap. iv. years, when the permanent teeth appear. The wisdom teeth we do not take into consideration, as often they are not cut at all. The following table shows the mean period of the eruption of each tooth. It thus appears that from three to five years Man has the minimum number of 20 teeth; from seven to twelve, 24; from fourteen to sixteen, 28 ; and later on, the maximum number, 32, not reckoning anomalies in the shape of supernumerary teeth.

Sometimes, in the interval between the two periods of eruption, search must be made at the bottom of the alveolus, or we must judge from the projection of the anterior sur- face of the alveolar border, as to the time when the tooth is about to make its appearance. In old age, when the teeth naturally fall ■ Chap, it.] CHARACTERS OF THE TEETH. 137 out, we shoidd look to see how far tlie alveolus is closed or fiUed up. The molars fall out first. "We may guess the prohable age on the iuferior maxilla hy the number of empty alveoli, hy the amount of absorption of the alveolar arches, and by the senile indications already mentioned. There is another method of ascertaining the age, namely, by examining the amount of wear and tear of the teeth. The deciduous as well as the permanent teeth wear out, but the latter more so, on account of their much greater length of use. The molars and canines are generally the most worn, but in the inferior or prehistoric races the incisors axe frequently worn down one-half or four-fifths of their height. M. Broca lays down four degrees of wear : in the first, the enamel is alone worn ; in the second, the tubercles of the crown have disappeared and the ivory is exposed ; in the third, some portion of the height of the tooth is reduced ; in the fourth, the wear has extended to the neck. The last is seen in old age, but it is more often the result of particular habits, as that of chewing the betel-nut, among the Malays, or working with the teeth on skias, among the Esquimaux. The tubercles of the first molar are soon worn down, occasionally by the commencement of adult age ; those of the second molar are more persistent. In a word, the determination of the age of a cranium is reduced to a balancing of probabilities : the condition of the sutures deciding the question in one way, the wearing away of the teeth or the ■character of the jaw in another : we should take the mean. At two or five years one can scarcely be deceived ; taking the period from 22 to 38 years it is more difficult to decide. Distinctive Characters of the Teeth. We cannot conclude this chapter without statiug the principles by the guidance of which the archaeologist or the anthropologist may discover the alveolus to which any isolated tooth belongs. The teeth of the second dentition interest us most in this respect. The four kinds may be recognised as follows ; the incisors are sharp at the edges, the canines have a single and conical point, the small 138 DISTINCTIVE CHAEACTERS OF THE TEETH. [Chap. it. and large molars a flat and tuberculated crown. The difficulty is to know to wMoh jaw and to which side of the jaw they belong. In a general way, the teeth of the upper jaw are larger than those of the lower, with the exception of the large molars, where it is often the reverse. The incisors may be recognised in the same way ; the middle incisors of the upper jaw, and the lateral of the lower, are the largest. The upper canines are not only larger but longer. The second character has a certain value. The curve which the superior dental arch describes is wider than the inferior, and its posterior branches are turned outwards, whUe those of the inferior arch are turned inwards. It follows from this that the two arches do not exactly agree, the upper incisors passing a little in front of the lower, and the crown of the upper molars overlapping, on the outside, the crown of the lower. The wearing away, then, of any one or more molars begins on the inner side on the upper jaw, and on the outer on the lower. Hence, also, the plane of this wearing down is considerably oblique inwardly as regards the upper teeth, and oblique outwardly as regards the lower. For the same reason the sharp border of the lower incisors is worn slopingly on the anterior surface, which causes them to be easily recognised. The third character has reference to aU the teeth, but especi- ally to the incisors and canines, and then to the small molars. Of the two lateral surfaces of the tooth, the internal — when we are speaking of the front teeth — or anterior, when speaking of the side teeth — is relatively plane and vertical ; the other, external or posterior, is swollen and convex, and sKghtly mammillated close to the crown. — (Colignon). The fourth character has sole reference to the molars, and is derived from the tubercles on their crowns — two on the small and four on the large molars. The largest tubercle on the smaE. molars is on the outside ; the groove which separates them is somewhat deep in the upper, and is occasionally interrupted by the vestige of a third tubercle in the lower. The four tubercles of the large molars are separated by a cross-shaped sulcus, and sometimes a fifth tubercle is noticed. The wisdom tooth has usually only three Chap, iv.] DISTINOTrVB CHAEACTERS OF THE TEETH. 139 tubercles — two external and one internal ; or its crown presents tlie form of the letter S, the posterior branch of -which commences on the inside, and the anterior branch terminates on the outside by doubling upon itself. In reality, its tubercles exhibit the same arrangement as the adjoining great molar, but are less definite, and, as it were, rudimentary. The fangs furnish the last characters of ■which we shall speak. The small molars have usually but one, except the second upper, which has frequently two. The large lower molars have two fangs, an anterior and a posterior, which are curved shghtly the one towards the other, and converge at the point. The upper have three fangs, one internal and two external, which diverge, because the inferior border of the maxOlary siuus passes between them (Broca). In the large lower molars, the fang which is behind is by far the larger ; in the upper, the intermediate one is the largest. The wisdom tooth has the same number of fangs as the adjoining molars, but they are generally consolidated into one or two. Lastly, the fangs of aU the teeth, but especially those of the incisors, the canines, and the small molars, have their points curved outwards or backwards in the direction crossing the arch. — ■ (CoUgnon). We may add that the crown of the first large molar bears some- times a resemblance to that of a small molar, and the first smaU molar to a canine. The first large molar is the strongest, the third has the lowest crown. The milk teeth may be recognised by the following marks : they are bluish-white in colour, and not of the yeUowish-blue tint of those of the second dentition. The incisors and canines are smaller, and have shorter fangs. The two milk molars are larger than the two small permanent molars ; they are multicuspidate, and not bicuspidate, having three tubercles on the outside and two on the inside. They have more the appearance of large molars than of the smaU. molars which succeed them. If we take, then, the head alone, it is easy to determine the age ; if the rest of the skeleton, with the exception of one or two bones, we arrive at the same result. The indications are still derived from the evolution of certain parts. 140 OSSIFICATION OP THE LONG BONES. [Chap. it. Ossification of the Long Bones. At tte end of the fourth week of intra-uterine life, the points of ossification of the clavicle make their appearance ; then those of the lower jaw ; from the thirty-fifth to the fortieth day those of the femur, the humerus, the tibia, the superior maxilla, the vertebrae, and the ribs ; about the fiftieth day those of the cranium ; and then — of which there is some doubt — of the scapula, &c. Ossification continues to go on ; the points of the extremities, or epiphyses of the long bones, become united to one another, and then to the body or diaphysis. Of course the length of the bone furnishes some evidence of the age, but the following data are preferable. The periods indicated represent the mean of the variations observed and recorded by authors : About 5 years, the scaphoid, the latest formed cf the bones of the tarsus, is ossified. „ 12 „ the pisiform, the latest formed of the bones of the carpus, is ossified. 14 „ the three portions of the iliac bone are united. 14 „ the inferior extremity of the radins is united to the body of the bone. 15 „ the superior extremity of the ulna is united to the body of the bone. 15 „ the lesser trochanter of the femur is united' to- the greater. 15 „ the coraooid process is united to the scapula. 16 ,, the caloaneum is ossified throughout. 17 „ the greater trochanter is united to the head of the femur. 17 „ all the points of the inferior extremity of the humerus are united. 17 „ the epiphyses of the phalanges of the fingers^ are united to the body of the bone. 18 „ the super' ir extremity of the femur is united in its entirety to the shaft. 18 „ the inferior extremity of the humerus is united to the body of the bone. 18 „ the inferior extremity of the tibia is united to the body. 18 „ the inferior extremity of the fibula is united to the body. 19 „ the epiphyses of the metatarsal bones are united to the body. Chap, it.] DEyELOPMBNT OP THE EOEB-AEM. 141 About 19 years, the superior extremity of the humerus ia united to the body. „ 20 „ the epiphyses of the metacarpal bones are united to the body. „ 20 „ the inferior extremity of the femur is united to the body. „ 20 „ the inferior extremity of the radius is united to the body. „ 20 „ the inferior extremity of the fibula is united to the body. „ 20 „ the inferior extremity of the ulna is united to the body. „ 20 „ the body of the sphenoid is united to the body of the occipital. „ 20 ,, the patella is completely ossified. „ 20 „ the sacral vertebrae are auohylosed together. „ 45 „ the xiphoid cartilage is anchylosed to the sternum. „ 50 „ the coccyx is anchylosed to the saornin. It is said that dining foetal life the body is developed more rapidly than, the head. The extremities, M. Sappey says, are formed from their free extremity to their root ; the greater part of the hand and foot appears in the form of huds attached to the trunk ; then the fore-arm and the leg, the arm and the thigh, successively m.ake their appearance ; the divisions into fingers and toes appear the last. When first fully formed the various segments have not the proportions -which they have at a later period. The femurs, smaU at first in. proportion to the body, afterwards become relatively large. The same with the humerus. M. Hamy, taking the measurements of Sue, G-unz, Liharzic, and others, has shown that about the fourteenth day of intrar-nteriae hfe, the fore-arm of the European is longer than the humerus ; while from about two months and a half it gradually becomes smaller. At this period the length of the fore-arm, in proportion to that of the humerus, is as 88 to 100; at birth this relation is 77; and from 5 to 13 years reaches 72, which it henceforth preserves. In the adult Negro this relation is higher ; from which M. Hamy concludes that the proportions of the fore-arm, relatively to the arm, are at first of the Negro character in the European, and assume their true character at a later period. Other modifications, some connected with evolution, others with the biped attitude, are exhibited ia the inferior extremities. The pelvis at birth is relatively narrow, and, as a consequence. 142 DEVELOPMENT OF THE EEMUE. [Chap. it. tlie great troclianters appear more projecting. The angle ■whicli the neck of the femur makes with the body of the bone is very mde, and the two femiors fall almost perpendicularly. At adult age the pelvis enlarges ; the trochanter femoris is less projecting ; the angle of the neck is less open — from 125 to 130 degrees in the man, and approaching a right angle in the woman (Humphry) ; the shaft of the hone is very oblique, owing to the inferior extremity making an angle with the perpendicular, looking from above, of about 15 degrees. In old age the angle of the neck is still diminished, and in the man reaches about 110 degrees ; the pelvis appears larger, and the great trochanters are less prominent; lastly, the curve, with its concavity looking backwards, is increased. We may add, incidentally, that the angle of the neck is smaller, and the obliquity of the femur more pronounced in short men : it is the same in woman, according to Humphry. These two anatomical conditions of the femur — the obliquity estimated by the angle which its extremity makes with the vertical, and the angle of its neck with the diaphysis — have been the Subject of special study by our colleague. Dr. Kuhff. His researches have been carried out upon twenty-four femurs, and the following are the mean results obtained in reference to these two points : Angle of Angle of Number. obliquity. neck.

The results agree very closely with those of Mr. Humphry. One of the causes of the diminution of the stature at an advanced age is the sinking of the neck. Another, stiU more important, is the subsidence of the intervertebral discs, which takes place for the most part anteriorly, whereby the whole of the trunk is bent forwards. Osseous vegetations are thrown out between the body Chap. IV.] DIFFERENCES IN THE SKELETON. 143 of one vertelDra and that of another, wMch tend to strengthen the column and to limit the incurvation. If the first task of the anthropologist, Trhen called upon to give his opinion upon human remains, is to determine their age, his second is to ascertain the sex. Both studies concern Man in his ensemble, and not Man in his ethnic varieties. It is of the latter therefore that we shall speak ia this place. Sexual Differences in the Skeleton. There is no appreciahle difference in the skeleton in infancy, and up to puberty ; its features are rather of a feminine character. At puberty, the line of demarcation commences, but the characters are not thoroughly defined until 20 years of age and upwards. At about 45, or upwards, the distinctions of sex become less marked, and at advanced age are but trifling, though the general character of the skeleton is rather masculine. The principles which govern the sexual differences in adult age may be summed up ia a few words. All the parts of the female skeleton are lighter and more frail; the general contour is more soft and graceful; the eminences, processes, or tubercules, are smaller and less marked. If there is one well-established physio- logical fact, it is this : that the asperities which serve for the insertion of muscles are developed in proportion to the . activity of those muscles. Less marked in the studious man than in the labourer, these asperities are still less so iu the woman, especially in women residing in towns. This law is so exact that we can tell by the degree of prominence of the crests and processes, what muscles the individual was most in the habit of using, and hence judge as to his profession or calling. As a sequence of these prominences, the depressions, grooves, and marks are more distinct in the man. So the temporal ridge, which serves superiorly for the insertion of the temporal muscle, and the transverse ridges, which divide the internal surface of the scapula, and serve for the insertion of the subscapularis muscle, are more marked in the male ; the 144 SEXUAL CHARACTBES OF THE SKELETON. [Chap. iv. groove of torsion of the humerus is more visible, and the two S-like curvatures of the ciaviole are stronger. In the woman, on the contrary, the external protuberance of the occipital, and the two subjacent curved lines which serve for the insertion of the muscles of the nucha— the anterior tubercle of the tibia to which the triceps femoris is attached — ^the tuberosity of the radius which gives insertion to the biceps of the humeriis, are less prominent — the curved alveolar borders are more regular — the borders of the malar bone are less thick — the canine fossa is less deep. In a word, it is tolerably easy to determiue the sex by the appearance of a bone ; in the case of a long bone, we are rarely in doubt ; in a short bone, as the calcaneum, it is stiU possible to do so. But we must not be surprised if we are occasionally at fault ; by making a comparison between one bone and another, the difGiculty will be cleared up. Suppose we took the clean-shaved head of any individual, the beard being removed, or the hand, or foot, the rest of the body being concealed, anyone, particularly after a little practice, would be able to tell whether the part belonged to a man or a woman, though it might be sometimes difficult to do so. Both, whether spontaneously or by reason of the work in which they had been engaged, or owing to exposure to the air, would have aU the appearances of the opposite sex. On the skeleton, a woman who had worked hard all her life would have the bony prominences and the processes for the articulations of muscles more developed, probably, than a man who had not worked at aU. Let us consider two organs only. The woman has the crests of the ilia larger and wider, in other words, the lips more prominent ; the subpubic foramen is of a triangular shape, while in the man it is irregularly oval ; the symphysis pubis is shorter, the subjacent arch is broad-pointed, while in the man it forms a very acute angle, and the cotyloid cavities are more expanded. In a word, all the transverse diameters of her pelvis are increased, while in the man the vertical are the more so. In 113 male pelves, the maximum width to the length, or maximum height, was as 125-5 to 1000, and in the woman, as 135 to 1000. The mean relative width to the height of the individual in each sex, is as 160 to 1000 in the Chap, iv.] SEXUAL CHARACTERS OF THE SKULL. 145 man, and as 174 in th.e -woman ; that is to say, fourteen-tliousandtlis more in tlie latter. Tlie head of the ■woman is smaller and lighter, its contours more delicate, the surfaces smoother, the ridges and processes not so marked. The superciliary arches are hut little prominent; the external half of the superior orbital border is thin and sharp {Broca). The forehead is vertical below, projecting ahoYe. The occipital condyles are small, as also the mastoid and styloid pro- cesses. The zygomatic arches are slender. The cranium in its ensemble is less high and longer. The subnasal portion of the face is more prognathous in the -white races, less so in the black. The inferior maxilla is smaller, its posterior angles ha-ving no projecting roughnesses. The frontal siuuses are less developed, &c. Of aU these characters the most important and the only ones easy to measure are the smallness of the head, the less capacity of the cranial ca-vity, and the relative hghtness of the brain. Then the obliteration of the glabella, the thro-wing out-wards of the superior orbital border, the smallness of the inion, the slight pro- jection of the occipital curved lines, and, lastly, the more abrupt angle, more nearly approaching a right angle, of the forehead at the level of the frontal protuberances. Five times out of sis ■we may decide the question -with certainty ; M. Mantegazza says nine times out of ten.* It may be asked, What skulls should be preferred upon ■which to study the races of Man ? With Van der Hoeven, we reply, those of men. No one -would be so bold as to say that ethnic characters are best exhibited in the cranium of the infant; but the skeleton of the -woman is intermediate between that of the infant and the adult man. Ha^ving considered the skeleton, we must take a brief glance at other questions in relation to age and function in Man and animals.t * P.

L 14.6 PHENOMENA OF REPEODUCTION. [Chap. iv. The Temperature of the Body, Some degrees above zero (centigrade) in most animals termed cold blooded, as reptiles and fisbes, is some degrees higher in birds and mammalia, which are both warm blooded. Moreover, it varies but little in the latter. The temperature of Man (in the axilla) is 37"8 centigrade ; that of the hare and squirrel is the same ; that of the horse is 38 ; of the ox, 38 '5 ; of the bat and the whale, 38'8 ; of the tiger and panther, 39 ; of the ordinary monkeys, 39'7 {Nogii}^); of the wolf, 40 'S. The Pulse Varies considerably. It is from 70 to 80 iu the minute in the adult man ; from 25 to 28 in the elephant ; from 36 to 40 in the horse ; from 45 to 50 in the ox ; from 70 to 80 in the pig, the sheep, and the goat ; from 90 to 100 in the dog ; from 120 to 140 in the cat ; 175 in the dormouse ; 200 in the mouse. Phenomena of Reproduction. These exhibit still more marked differences. Three points here demand our attention, viz. the duration of gestation, the number of young, and menstruation. Generally speaking, in the mammahan series, the circumstances which are favourable to reproduction are in direct ratio to the shortness of life. The smaller species carry their young a shorter period than the larger, and have a greater number of young at a birth. In the following list we see the place occupied by Man. He has two at a birth more frequently than the monkey tribe,. and exceptionally he has three or four. Period of Gestation. Number of Weeks. young.

The phenomenon is identical with that called " rut " in animals. Duration of lAfe. The mean duration of Ufe in Man is at the present time, ia France, about 40 years,* and the ordinary duration from 70 to 80. Some individuals, exceptionally, live beyond 100 years. Beraud says, one in 3100 ia England. Prichard mentions that in the year 1799, Eastron had collected together 1712 cases of centenarians : of this numher, 277 had attained from 110 to 120 years; 117 from 120 to 150; and eight from 150 to 180. He also gives a great number of other equally well-authenticated and not less extra^ ordinary cases. With some exceptions, Man is the most highly favoured of the mammalia as regards longevity ; the reproductive faculty continues longer, and he enjoys a long old age. But is not this due to the care which he takes of himself? The average duration of Ufe in Europe is increasing, while in countries where the people go about naked it is decreasing. Among animals, longevity is generally less in the smaller species. The pig lives to the age of 9 years, the dog from 15 to 18, the * " Sur le Pretendue Degen&eaoenoe de la Popnlation Prangaise," by M. Broca, in " Bull. Acad. Med." 1867. L 2 148 GENERAL PtnSTCTIONS. [OhaI?. iv. bear from 20 to 25,* the horse and the ox to 20, the camel to 45, the elephant from 150 to 200 years. As regards the three higher anthropoids, the average duration of life is from 40 to 50 years. General Functions and Psychical ManifeMations. Man inhabits every region of the globe, and inures himself to all climates and to aU conditions of Ufe. Whether at the pole or the equator, on the highest mountains or in the deepest valleys, in arid deserts or unhealthy swamps, nothing seems to -daunt him. The- Esquimaux are to be met -with up to 80 degrees north. There are- those who live and thrive in the Andes and the Himalayas, at an altitude of 4000 or 5000 mtoes and upwards ; and we find in- habitants even in those vast regions in which Livingstone travelled up to his middle in water. From 47 degrees cent. ( = 116-6 Fahi.) in the shade, as observed in Senegal, to 56 below zero ( = 100 degrees Fahrenheit below freezing-point) at the poles, are the extremes of temperature which he is able to support. Some animals readily adapt themselves to the most opposite conditions of climate, as the- dog ; others are unable to bear such changes, as the reindeer, the- bear, the lion, the whale. This is how the disappearance of certain- geological species, as the megatherium, the mastodon, and th& mammoth, is to be accounted for. The anthropoid apes live in communities in certain circumscribed regions ; the goriUa and the chimpanzee on the west coast of Africa, at about 15 degrees north and south of the equator ; the orang in Borneo and Sumatra ; the gibbons in India, bordering on China and Malacca. M. Schwein- furth has discovered a new species of chimpanzee on the banks of the Upper White JSTile. Other species have been described,, belonging to the tertiary epochs, in different parts of the globe, especially in France. We may remark that the anthropoids are only to be met -with in hot countries. This power which Man possesses, of more or less readily accustoming himself to any climate, is to be accounted for from the fact (1) That he is omnivorous; * A bear cubbed in one of the pits in Berne, is said to tave reached the: age of 47 years. Chap. IV.] GBNEEAL FUNCTIONS. ,149 and (2) that he knows how to clothe himself and to manufactuie weapons and implements. The Esquimaux suhsists on oil and the flesh of seals; the Todas of the Wilghemes on milk and pulse. Some tribes live on fish and shell-fish, and take sea water as a beverage. Others miK clay with theic food, while civilised nations obtain their supplies from all sources. Man cooks his food, but he does not despise the raw mpHusk, or undressed fish, or the raw flesh of the mammalia. Unlike any other animal, he rears cattle and devotes himself to agriculture. He makes use of various animals, as the dog, the cat, the camel, and the reindeer, to sub- serve his own purposes ; and even his feUow-creatures, be they black or white, are equally under his dominion. In this respect some animals imitate him — as the red ants in their treatment of the black ants. The majority of animals possess natural means of protection and defeiice. The goriUa has a fur peculiar to himself, powerful canine teeth, and a muscular system of extraordinary strength. Other mammalia possess agility and swiftness in runnihg, which enables them to escape from enemies. Man has nothing of the kind. " leaked and without weapons," such is Linnseus's definition of him. All his various methods of operation he owes to his industry. Prom the remotest period he has made use of fire, and has manu- factured flint implements. The anthropoid ape has never known how to make use of a stafi', to put up a fence, to make a fire, nor to construct a habitation which can be dignified by a higher title than that of a nest.* The negroes of the islands in the Indian Ocean, who live in trees, or sleep under bundles of sticks laid against a rock, do so from indolence or indifierence, rather than from incapacity. The lowest savages known have some notion of drawing ; they know at least how to make a cross or a round in imitation of objects which they see around them; and, for our part, we attach but little credence to the statement made by Old- field, that the aborigines of Western Australia are unable to * Livingstone saw one of these enormous nests oonstmoted by tlie soko, one of the ohimpanzeea.

[Chap. it. distinguish. th.e figure of a tree from that of a ship. In the same region, other travellers hare observed, on the contrary, that they possess a certain amount of intellectual capacity. It would have been ■well if Oldfield had given some case in verification of his stat6m.ent. Among aU races of mankind there exists the desire to please, or the love of dress. In civilised countries it is more developed in the woman, among barbarous tribes it is more so in the man. Some tattoo themselves, or suspend various ornaments to their ears, or to the septum of the nose, while others dye their hair, or sharpen their front teeth iato poiuts. Something analogous has been observed iu domestic monkeys. Many tribes cannot count above two, and are less favoured in this respect than the magpie, which ean count up to three, some say up to twelve. But aU have some notion of number. A Bosjesman, however, although in- telligent in other respects, was incapable of adding one and one together. Man is not to be distinguished from animals as regards his family relations. He is monogamous or polygamous, and the woman is similarly polyandrous. The gorilla and the chimpanzee are mono- gamous, very jealous of the fidelity of their partners, and very devoted in their attentions to them. Man, likewise, attaches him- self without hesitation to those of his own kindred. He lavishes his care and love on his offspring beyond the period of lactation, and up to that when they are able to look after themselves. If this period should be prolonged beyond puberty it is owing to the customs of society. The ceremonies which among all savage tribes mark the progress from infancy to manhood also mark the period at which Man acquires his independence. Maternal affection, with aU its evidences of blind devotion, is, with rarest exceptions, universal The father exercises authority over the life of his children ; he practises infanticide openly at his will and pleasure, in the same way as the son, at a later period, disencumbers him- self from his parents who have become a burden to him. The Todas destroy in the cradle aU their female children beyond a certain number, as being useless, in the same way as they kill Ohap.it.] sociability. 151 all their male buffaloes but one, because tbey do not give milk. In a state of nature Man considers utility first, and refers every- tbing to his wants, his family, and so on. It must be confessed that in the social condition there is much of this sort of thing under a less rough exterior. Selfishness is well known to be the moving principle almost universally, and is only limited in its action by a fear of the law, or by education. Man lives in society because he is compelled to do so, like many other animals. Being endowed with the faculty of language, and with exalted intellectual powers, he wants to exercise them, having in view also the more ready satisfying of his material wants, and the realisation of a larger amoimt of comfort. Emulation, which results from this, is the most powerful cause of progress in the physical, moral, and intellectual world. The larger the community, the greater the amount of rivalry ; and the more fierce the contest, the" more rapid the progress. A great number of animals also seek the society of their fellow- creatures, and work in company, as the beaver, the buffalo, the Austrahan dog, the horse, the swallow, the bee, the ant. The soko, an anthropoid ape, lives in a troop of ten individuals on the banks of the river Lualaba. Many species of monkeys, like Man, select a chief, who directs their operations and to whom they submit. The howlers, or mycetes, belonging to the cebian family, hold meetings in which one of them speaks for hours at a time in the midst of general silence, succeeded by great excitement, which ceases as soon as the speaker gives the word of command. Other monkeys combine together to plan an incursion; divided into detachments, some plunder and tear up roots, others make a chain for the purpose of carrying them from hand to hand ; others are placed as sentinels to keep watch. In unexpected danger, the sentinel gives the alarm and all decamp. It has been remarked that if it happens that the troop is surprised, owing to the fault of the sentinel, there is a grand hubbub in the neighbouring forest during the night, and on the morrow the body of one of the plunderers is found, to aU appearance having been put to death by his companions. 152 RELIGIOUSNESS. [Chap, it, It has been said that one of the characteristics of man is religious- ness, that is to say, "the faculty of belief in something above human understandiag." Would it not be better to define it as an iuternal impulse, which prompts us to individualise the unknown and to make him. the object of adoration 1 * Be it as it may, many, even among the most civilised, have neither this belief nor this impulse, and are satisfied to Kve without troubling themselves as to that which they do not comprehend ; they have neither fear, nor reverence, nor gratitude — ^the three causes of religious conceptions. There are nations and tribes with- out religion and without any mode of worship, and who believe only in wizards or fetich. It is true they make every form of superstition to subserve their religiousness. But some African or Melanesian tribes have not even superstitions.t ISTeither good luck nor misfortune affects them ia any way. If, * It is impossible to take religion in its strict sense as the faculty of beHeving in a god ; if so, half of the population of the globe would be destitute of it. Taking Buddhism alone, there are three or four hundred million votaries of this " religion without God, founded on charity amount- ing to madness." — Laboula/ye. t Nothing requires such calm and impartial judgment as the inquiry into the moral and religious condition of savage tribes. Burchell, through his interpreter, addressed two or three questions to Bosjesmans, and im- mediately came to the conclusion that " they were brutes, because they did not answer the simple question : What is the difference between a good and a bad action ? " Oases of this kind are very common. Other travellers, less impulsive, perseveringly inquired into their beliefs and superstitions, and came to the conclusion that they had no conception of anything outside themselves, and were persuaded that they die in the same condition. Which are we to believe ? Such a thing is rare as a rule. All missionaries, to whatever church they belong, are impressed with the conviction that savages believe in a god, in the existence of a soul, and in the deluge ; while independent travellers arrive at altogether different conclusions. The fact is, the savage endeavours to please those from whom he is Ukely to gain something. He understands the wishes of the missionaries and satisfies them. It is absolutely undeniable that the absence of all abstract ideas is a very common characteristic of savage tribes ; terror causes them to see evil spirits everywhere, and to create for themselves fetich, but the opposite feeling, the recognition of that which does them good, induces them to con- ceive of beneficent spirits. Chap, iv.] MORALITY. 153 after long abstinence, they get a windfall, they eat and think of nothing further. In this respect Man is iaferior to the dog, which maintairis a devoted attachment to the hand that brings him his daily food, to the master, who is to him as a God. Assiiredly this animal has a belief in. something above him. Say if those birds which warble their songs at the rising of the sun are not moved by an internal impulse to praise nature for the infinite pleasure which she bestows upon them ? This is but little removed from adoration. Man alone has an idea of duty — a morale. Is this certain? And of what kind of morality are we to speak first — of that of the peasant or of the noble — of the morality of the laws or of natural morality? A very remarkable English work* mentions that moraKty is essentially variable, progressive, and perfectible; that it is a reflex of wants, of usages, and of circumstances ; what is good here, is bad elsewhere — as to take care of one's infirm parent, or to bury biTn aUve.Y Its radius, he says, has gone on enlarging for ages, from the inferior to the superior races ; at first consisting only of the family, it has since extended to the whole tribe ; that which was evil in one was good in other tribes. Thence it has spread far and wide and has become international. " Morality or ethics," says Mr. Tylor, "signifies the act of conforming to the manners (mores, fjdri) of the society to which we belong. There are not two races in the world which have exactly the same code of morality, but each has its own, which is sanctioned by pubhc opinion." At the present moment throughout Europe do not the rules of morality change in the event of war? Tylor's most approved criterion, " Do not to another that which you would not have done to yourself," applies to animals as well as to man. The dog knows that in order not to be bitten he must not bite, and acts accordingly : he has also his morahty. Man possesses consciousness of that which philosophers call le moi, that is to say of himself, of his personality. It would be * " Primitive Culture," by E. B. Tylor. Second edition. London, 1873. Translated into French; Eeiswald and Co.'s edition. Paris, 1876. 154 MENTAL FACULTIES. [Chap. it. strange if animals had it not also. Man lias the sense of the nohle, of the just, though he has many ways of expressing it. He grasps the relations of cause to effect ; the animal does the same. He possesses spontaneity, ■will, the power of balancing probabilities : but is it not so with animals'! Madness even is not peculiar to man.* M. Houzeau has worked out this subject in a masterly manner in his two volumes on " The Mental Faculties of Animals." But Prichard, the most orthodox of anthropologists, had previously devoted a long chapter to the consideration of their psychical en- dowments {facultes psycMques). There is also a work in the " BibUothfeque des Sciences Contemporaines," which treats of aU these questions.+ But to the anthropologist, or the unprejudiced naturalist, the inference is obvious. Between Man and most animals there is no absolute radical difiference in intellectual arrangement. All the faculties of Man are to be found, without exception, in animals, but in a rudimentary state ; some are very highly developed, others more so even than in ourselves. It is not the exclusive possession of special faculties which gives us our supremacy, our judgment, our intelligence, our correctness of observation ; but the measure of these, and, bettor still, our holding them in perfect equilibrium. In a madman we continually notice a faculty of rising to a higher state than that which the sane man possesses. Keep this well in view, and the madman would appear to you to be a genius ; but at the same time other faculties are debased, there is a loss of balance, and consequently a less amount of reason. The intellectual characteristic of Man in general, and especially of the man of wisdom, is the exact equilibrium of aU. his faculties, and not the increase or exaltation of any. Another physiological character connected with the function of the brain, which anthropologists look upon as peculiar to man, is * See " Traite de la Folie des Animaux et de sea Bapports aveo oelle de I'Homme," by Pierquin. Two vols. Paris, 1839. t See also " L'Anatomie Comparfe du Syet&me Nerveux," by Lenret and Gratiolet, vol. i,, chap. " Facultes des Mammiftres." Paris, 1839. Chap, iv.] FACULTY OF EXPRESSION. 155 the faculty of language, or that of uttering articulate sounds. Ac- cording to the doctriae of the derivation of Man from less perfect animal forms, Man -would have taken his origin from the moment that he was put in possession of this faculty. Faculty of Language. Many, if not all, animals communicate to one another their thoughts relating to their usual life ; they have intonations and modulations of voice, each of which has a distinct and definite meaning. They variously express fear, joy, suffering, and hunger. They make themselves understood by those of their own species, of their own family, of their own young ; they warn them of the approach, of the nature, and of the amount of danger. But, as a general rule, they do not articulate. Some of them join together a few consonants to vowels, hut they repeat them without change. In this respect the notes of birds would better deserve the name of language. Let lis explain. There exists in Man and animals, and common to them both, a general faculty called that of expression (Gaussin), or the faculty of connecting an idea with a sign. Its various manifestations are the faculties of mimicry and of speech ; pro- bably also music and drawing. The mimic faculty evidently exists in animals. The dog which stands at game, and runs back to see if his master is in pursuit, or which scratches at the door to be let in, is a proof of this. It is not surprising that the animal does not possess the faculty of delineation, seeing that it has not the perfect hand of Man, nor has it been instructed. We can simply allude to the hum of insects produced by the friction of their elytra, and pass on to the vocal faculty. There is not the slightest doubt that animals express their ideas in this way. M. Coudereau has taken great pains to analyse the language of the hen, and the numerous intonations corresponding to each order of ideas, which are pro- voked by the small number of feelings and wants in connection with its humble existence. But in this, and probably in that which is uttered by the howling monkey, are there not articulate 156 FACULTY OF LANGUAGE. [Chap. iv. sounds, or syllables, more or less jumbled together, wHob deserve the title of language ? "We must remember that the primitive languages spoken by Man were monosyllabic. All philologists tell us so, and that very few elementary syllables were sufficient at iirst to constitute an articulate language. The question then resolves itseK iuto this : How many articulate sounds or simple syllables would be required to constitute a language, and where is the lias to be drawn between the relatively perfect language of some species of animals, and the primitive language of the lowest type of our own progenitors ? Of course we are not referring to the parrot, which attaches no meaning to its utterances, but to monkeys, which make use of different syllables, each having a distinct meaning. We win now analyse the mechanism of human speech. The air expired from the lungs enters into vibration in the larynx, where the voice is formed, and passes through the mouth, where articulation takes place. The muscles of the larynx modify the former, the muscles of the vault of the palate, of the tongue, of the cheeks and Hps, have to do with the latter. But these also contract for other purposes, and are supplied by different nerves. The stimulation of these nerves at their origin would only produce irregular contractions having no definite object. There are then besides special centres, having distinct functions, in which the appropriate movements are co-ordinated, and to which the mental impressions are conveyed. Thanks to the experience with which nature favours us in the living body, the centre, in relation not only with articulation in general, but vsdth each particular system, is well known. When the quadrilateral* indicated by M. Broca, at the posterior extremity of his third frontal convolution, especi- ally on the left side, is affected by an acute lesion, the faculty of articulating is disturbed or altogether suppressed, f * See page 109 on the Seat of the Faculty of Language. t In microcephales, who have never teen able to learn to speak, the third frontal convolution has been found atrophied. It has been asked why the faculty of language should appear to be looaUsed, or rather is the more Ghap. IV.] . FACULTY OF LANGUAGE. 157 The phenomenon reduced to its most simple expression is termed aphemia. The individual preserves his intellect, expresses his ideas by gestures or by writing, moves his tongue and lips, and has power of voice, but is unable to articulate ; his general faculty of expression remains, but he has lost the power of speech. At other times the lesion is more extensive ; he has stdl ideas, but is incapable of committing them to writiag or otherwise. Sometimes the lesion is stiU more considerable, and the intellect itself is affected. "We see then the series of operations which language requires, and to which so many more or less distiact organs lend their aid : (1) Thought and wiU ; (2) The general faculty of expression ; (3) The particular faculty of articulating ; (4) The transmission by nerves; (5) The execution by muscles. These functions are thoroughly in accord, and largely developed in Man, but is it not so in the animal 1 The animal has ideas, he possesses the faculty of expression and of articulating sounds, but aU this is in a rudi- mentary state. In Man, on the contrary, aU have assumed gigantic proportions ; his ideas have become multiplied ia the course of ages; his faculty of articulating has become perfected by use ; his nerves and muscles have learnt to obey him absolutely. And in the same way as an instrument gives out more harmonious sounds according as the fingers which play upon it acquire greater expert- ness, and the musical power which directs them greater force, so human language is the result of progressive development iu the often exercised from tte left side. Two explanations have been given ; that of M. Broca is tlie one generally admitted. We are not right-handed, he says, by accident, bnt beoanae the left hemisphere, which presides over the movements of the right side by the decussation of the nerves near their origin, has from the first a greater amount of activity. This excess of activity extends to all the fonotions of which this hemisphere is the seat, and notably of that of articulation. There are exceptions, nevertheless; that is to say, there are persons who originally, or after a lesion in the left hemisphere, speak with their right ; in the same way as there are some people originally left-handed, and others who have become left-handed in conse- quence of having lost their right hand. 158 PATHOLOGICAL CHARACTEES.

But is it tlie multiplication of ideas wMcli originally gave birth to language, or language whicli has given development to ideas'! This is the question.* CHAPTEE V.

Pathological conditions are merely deviations from the physio- logical state. They affect living organs, and have reference also to man's life generally. The chapter on pathological characters, although important, is only a sequel of our general division on physiological characters. The points on this horizon which inte- rest the anthropologist, only looking at the comparison of Man with the other mammalia, are of three orders : (1) The numher of diseases common to Man and animals, and the few peculiar to the one or the other ; (2) The disturbances in the regular de- velopment of the body, when they can throw any light on the problem of the origins of organisation ; (3) Particular alterations in the skeleton being capable of being confounded with the normal condition. The laws of pathology are the same throiighout the whole mammalian series as those of physiology, upon which they depend ; their effects, too, are generally identical. Animals, like Man, are subject to accidents, to faults of development, to diseases of an acute and transient nature, and to those which are chronic and of long duration. They have the troubles of youth as well as those * See " La Linguistique," by M. Abel Hovelaoque, 2nd edition, Paris, 18V6, " BibliotlatSqne des Sciences Contemporaines." Chap, v.] PATHOLOaiCAL CHARACTERS. 159 of old age. In both are observed inflammatory and rheumatic affections, eruptive fevers, typhus, the neuroses ; the only difference is in the country in which these diseases manifest themselves, and in the symptoms resulting from this. There is as great a difference between the diseases which attack Europeans and those seen in Negroes, as between the diseases of Man and those of animals.* Thus the eaux auxjambes (grease) in the horse is the same disease as the cow-pox of the cow and the small-pox of Man. Experiments by inoculation have clearly proved this. The scab of sheep is doubtless something of the same kind ; the pig, too, is subject to a form of small-pox. The congestion of the spleen of the sheep species becomes the eharhon in horned cattle, and the malignant pustule in Man. It is unnecessary to say that affections of the skin are not the same on the thick skin of the horse and on the delicate skin of the European. Between the latter and that of the K"egro there are also differences in this respect. So the nervous system being less impressionable in animals, the reaction is less strong, and the fever less apparent. Like ourselves, the animal is dyspeptic, asthmatic, tuberculous, scrofulous, or cancerous. Like ourselves, the constituent elements of his blood — the globule, the albumen, and the fibrin — increase or diminish, producing anaemia, dropsy, or scurvy. Eood other than the milk provided for their use, produces in their young diarrhoea, as in Man. They have the same swelling of the glands during the eruption of the teeth. A young orang died under our own observation owing to disorders of dentition, which arose while we were treating it as we should have done a human being. The acarus which produces the itch may differ in kind, but its effects are identical. Parasites in general, such as entozoa, vary, as in Man, according to cHmate,, but in the same way as those which infest vegetables. Hydrophobia is met with in the dog, the cat, the woH, the fox, the cow, and the horse, as ia Man (Trousseau). SyphiKs exists among apes.

[Chap. v. logical Society of London, in 1865, presented the three series of phenomena — ^the -ulceration of the sexual organs, the falling off of the hair, and the affection of the bones. The diseases of the brain themselves are not peculiar to Man. Animals exhibit many forms of delirium ; but they are more frequent in Man, owing to the im- portance of the organ ■which is their seat, as well as to the activity and delicacy of its manifestations. In a word, the pathological types are the same throughout the whole mammalian series, and are only modified according to species. The diseases peculiar to one or many species are rare, as glanders, which appears peculiar to Man and solipeds. Moreover, animal pathology has advanced but little, and has scarcely reached beyond that of our domestic species. Anomalies of development are, according to our idea, of four kinds. Some exhibit themselves physiologically during life : for example, giants and those afflicted with polysarcia ; others are con- genital, but can be modified or removed after birth ; a third kind are congenital and irremediable, except occasionally by surgical means, and are called monstrosities, or teratological phenomena ; a fourth are the organic anomalies described at page 126, under the name of Reversions. Among giants we may mention a Finlander, who was 2'83 mfetres in height, and a Kalmuck, whose skeleton is in the Museum Orfila, 2 '5 3 metres. Then we have dwarfs, but these are for the most part affected with rickets. The height of the celebrated B&M of King Stanislas of Poland was 89 centimetres ; another, 25 years of age and 56 centimtoes in height, was presented to Henrietta of France in a pie. The ordinary weight of the man is 63 kilogrammes, accord- ing to Qu^telet, and that of the woman, 54. We have seen dwarfs who only weighed from 4 to 8 kilogrammes. In polysarcia, or obesity, the weight is often more than 150 kilo- grammes. Two Englishmen, brothers, weighed, the one 233 kHogrammes, the other 240 (Sappey). Another Englishman, in 1724, measured 1 mfetre 72 centimtoes round the body, and was 1 m^tre 86 centimetres in height. Barrow mentions a half-caste Chap, v.] ALBINISM. 161 from the Cape of Good Hope, who lived twelve years in hia "bed,- and was burnt alive in it ; the house having taken fire, neither the door nor the window was found large enough to enable him to get out. Albinos are iudividuals iu whom the pigmentary matter is so far deficient that the skin and hair are colourless, the iris is trans- parent, and the choroid coat destitute of the dark pigment for the absorption of redundant rays of light. In consequence of this, they are unable to bear bright sunlight, and see better at night than during the day. Their eyeballs are affected with a perpetual oscUlating movement, their skin and hair are colourless, or of a duU white, the eyes reddish, the transparency of the tissues show- ing the blood circulating through the capillaries. They are often indolent; and without muscular vigour. There are partial albinos, in whom all the above symptoms are observed, but in a less degree. They may easily pass unnoticed among the white races, but are very observable among the black ; their hair is flaxen or red, their skin coffee-coloured or speckled, their eyes are light blue or reddish. Both are met with among aU. races and under all chmates. In some of the native courts on the west coast of Africa, especially in Congo, they are an object of veneration, and go by the name of " dondos." Dr. Schweinfurth has seen a great number of them with the king of the Monbouttous on the banks of the Bahr-el-Ghazel. Prom their presence among the blackest populations, Prichard framed an important argument in favour of the influence of external circumstances, and of the derivation of the human race from one primitive pair. He delighted to reiterate it, and more- over he was the first to establish the fact that their hair was as woolly and tlfeir features were as negro as those of their fellow- countrymen of the same tribe. "We say again, albinism is only a monstrosity, a pathological condition which has been cured, and we must take care how we place implicit reliance on the confused accounts given of it by travellers. A cutaneous affection called jntyriads versicolor is seen in whites, as a partial loss of colour of some portions of the skin, while the accumulation of pigment upon 162 MONSTROSITIES. [Chap. v. other portions causes them to appear of a deeper colour. The eyes- are not at all affected in these cases. Our opinion is that what has heen called in negroes piehald, and described as an example of partial albinism, is the same thing. The scaly affection called ichthyosis, often of a marked hereditary . character, to which Mr. Darwin frequently aUudes, and the subjects of which deserve the title of porcupine men, has no interest for the anthropologist. Two individuals, Eussians by birth, were recently exhibited in- Paris, called dog-men, whoso bodies were covered with a quantity of lon^ coarse hair ; they were also said to have exhibited a defective development of the teeth. Similar cases in Bnrmah and India have been described, which were hereditary through three generations. Monstrosities, of which there are many varieties,* are produced during embryonic or foetal life, either in consequence of hereditary- predisposition, of some accident to the mother, or from some disease of the f cetus. They arise either from arrest, excess, or perversion of development. Some are incompatible with Hfe, others do not interfere with it. "We are not about to give an explanation respecting the two theories — either the one as to the pre-existenee of germs, as maintained by Winslow, but now abandoned, and which means that the embryo represents from the very first the future beiog in his entirety ; or the other, that of Serres and Isidore Geoffrey Saint-Hilaire, called epigenesis, which we have described at page 128, and which admits progressive development. Among these monstrosities, we may mention polydactyHsm, or the existence of from four to seven fuigers, which has been noticed as having occurred through many generations ; inversion of the viscera, in which the heart is found only on the right side, or where' all the viscera are inverted ; the absence of one or more limbs ; herma- phroditism ; hypospadias ; imperforate anus ; hare-lip ; spina bifida ;. microcephalus, &c.

Perhaps we ought to speak of them as examples of supplementary limbs, as that of a girl of 14 or 15 years of age, exhibited the same year before the Anthropological Society by Dr. Ball. Monstrosities are not peculiar to Man ; they are freqvient also among animals. We shall only speak of those which are specially interesting to us as taking place ia the head, as microcephalus and hydrocephalus. Under the name of mental alienation we include all the various functional disorders of the brain. These may be reduced to three ^l) Mania properly so called, which breaks out in individuals hitherto sane, has t*o forms — the one of excitement, the other of depression — and is general or partial ; (2) Dementia, which is a general and progressive feebleness of all the faculties, and is of two kinds — accidental, or senile ; (3) Idiotcy, in which , the faculties have never attained their full development. In the three forms, the volume of the brain is increased or diminished according to the amount of disease, and according to the greater or less amount of blood which it contains. In ordinary mania there is rather an increase, and in dementia, sooner or later, a decrease. The lesion affects the entire organ, its central portions, its convolu- tions, and sometimes solely the gray substance covering them, and the functional disorder becomes permanent. It is impossible to be deceived, and true human superiority consists in knowing how to look the truth in the face. The most beautiful of our intellectual manifestations — ^those of which we are so justly proud — are the product of a material organ, in the same way as bile is the product of the liver, and the circulation is the product of the con- tractions of the heart. A sound and healthy brain produces sound judgment and understanding ; a diseased, bloodless, and impaired brain produces the reverse. That which distinguishes Man from the brute is the quality and quantity of the organ — ^the quaUty and quantity of the product. If mania and dementia only concern medicine, idiotcy has an interest for anthropology; it exhibits the brain sometimes less developed, more simple, more or less stunted ia growth, and approaching more to that of animals. M 2 164 IDIOTCY. [Chap. Y, There are many direct causes of idiotcy. Sometimes the volume of the brain is normal, but its convolutions are very large, generally less flexuous, or decidedly imperfect at some particular point. Sometimes it is hypertrophied, and its convolutions, though simple, are, as it ■were, piled upon one another, and tend to produce im- pressions on the internal surface of the cranium. Sometimes it is altogether atrophied, or only so on one side, in its frontal, parietal, or occipital lobes, in its central portions, or in a group of convolu- tions -which we have seen replaced by cellular tissue, or trans- formed into a serous cyst. In a case shown to us by Dr. Mierze- jewski, the parietal and occipital lobes were so shrunken, that the cerebellum was completely uncovered, as in the kangaroo. These apparently contradictory lesions explain why the weight of the brain of lunatics generally has not uniformly exhibited the dimi- nution which we might have expected, as compared with the brains of men of sound mind. It is the same with the cubic measurements of the cranial capacity. The cranium, at the termi- nation of infancy, may remain small, but at adult age and later it is unable to foUow the retraction of its contents, and to become less in size. After inspecting 520 crania of insane persons, collected by Esquirol, which form part of the museum of the Anthropological Institute of Paris, and setting aside the probable cases of hydro- cephalus, we may safely say that their mean cranial capacity is below the mean in men of sound mind. If one could obtain those of idiots — that is to say, those who have been insane from birth — there cannot be a doubt that we should find it the same in them. Cretins, which are to be found under various names in almost all mountainous parts of the globe, may be placed in the same category as idiots. The immediate cause of cretinism is by no means certain. But how singular that this widespread malady should take place under the influence of external circumstances acting upon the brain of the infant even during intra-uterme life ! The head is generally large, the figure that of an aged person, and the nose deeply sunk at the root, which has given rise to a theory of which we shaU speak presently.* * See " Treatise on Mental Diseases," by Greisenger. Translated into French by M. Baillarger. Paris, 1864. Chap, v.] MICEOCEPHALUS. 165 Microcephalus. All in wtom the brain has not attained a certain degree of development, or the cranial cavity a given capacity at adult age, are termed microcephales, whether such be really idiots or have only a general di mi nution of intellect similar to that of young infants. M. Broca divides them into demi-microcephales and microcephales proper. He says all the non-deformed crania of adult Europeans whose capacity is below 1150 cubic centimetres, and the horizontal cir- cumference less than 480 millimetres, if a man, and 475 if a woman, are demi-microcephales. The length and width are less positive ; moreover, we may consider crania to be demi-microcephales whose length is 163 millimetres and under, in the man, or 160 and under, ia the woman, and whose width is 133 in the man and 127 in the woman.* But the diminution continues still further, which brings us to the consideration of the true microcephales. Microcephalus is owing to a general or partial arrest or perversion of development ia one part of the brain, which manifests itself at various periods of intra-uterine life. It is ^merely an anatomical variety of idiotcy. The organ, in the absence of complication, con- ■tinues to grow, but irregularly and slowly. Its weight, at puberty, reaches from 400 to 500 grammes, according to M. Delasiauve ; it has been known to be 360 and even 240 grammes (Marshall). The cerebellum, Gratiolet states, is larger in proportion to the braia proper, and the convolutions are those of a foetus of five months. Atrophy is most frequently seen on the anterior lobes, and some- times on the posterior. The cranium has a capacity of from 300 to 600 cubic centimetres, a circumference of from 320 to 370 milli- metres, and a length of from 100 to 118. Two microcephales, of the ages of 10 and 15 years, mentioned by Vogt, had a mean of 333 cubic centimetres, and seven adults, a mean of 433. The mean, in six cases of all ages, from M. Broca's museum and laboratory, measured by M. Montane, was 440, and that of three of them * See Chapters II. and III. for the measurements of normal crania. 166 MIOROCBPHALTJS.

They affect especially the skeleton, bones deformed by disease being mistaken for sound bones. These morbid conditions either affect all the bones or only those of the cranium; the former include Tickets, inflammations of the bones, syphilis, old sores, and fractures. We refer the reader to works on pathology for the majority of these, and shall confine ourselves principally to rickets, and to some diseases peculiar to the cranium. Rickets. Eickets is a disorder of nutrition, in which the process of ossifi- «ation is arrested at the period when the osseous tissue is about to become thoroughly organised (Broca). It is less a disease than a state of suffering, symptomatic of an impoverished condition of the system. It exhibits itself from the third month of intra-uterine life, up to 18 or 2-5 years of age, when the skeleton has done growing {L. Tripier), but it is more frequent about two years of age. The softened bones become deformed and incurved, in con- sequence of the weight of the body, of the contraction of the muscles, and of accidental pressure. It is at the weakest point of the natui'al incurvations that the bending usually takes place. A character common to all these deformities is the following : By making a section of an old rickety long bone, the compact osseus tissue is thicker on the diaphysis at the concavity of the curve, and thinner at the convexity. Another effect of the disease is this : the epiphyses, owing to the stage of ossification being accelerated, are found anchylosed to the diaphysis before the bone has arrived at its full size, so that the child ceases to grow, and remains a dwarf and deformed ever afterwards. "We cannot there- fore depend upon any important measurement if made upon bones affected with rickets. The following are certain indications by which they may be recognised : In the clavicle the two curvatures are increased, especially the internal, which makes an abrupt bend. In the ribs the flatness and thinness are increased. 168 EICKETS OP THE CBANITTM. [Chap. y. In the humeras the curve takes place below the middle portion, its convexity looking forwards, forwards and outwards, or outwards. In the fore-arm .the bend is in both bones, or in one only, about the middle, and is from behind forwards, being accompanied by a certain amount of torsion. In the femur the angle of the neck is diminished, and the natural torsion of the bone is increased, the lower half becoming arched forwards or outwards. In the leg both bones are affected. The deformity never occurs in the upper part of the tibia, but at its middle and inferior portion. The most common is the curvature internally, which M. Broca compares to a yataghan ; the bone is flattened from before back- wards, its anterior border is more or less sunk in; its external concave border is sharp ; the internal, to which is attached the interosseous aponeurosis, is thick. The next form is that of an antero-posterior curvature, the section of which is triangular, and the anterior border is convex from above downwards, and sharper than usual ; it has the appearance of a sabre, but in an opposite direction. The curvature outwards or backwards is also met with, but less frequently. Ifumbers 2 and 3, Kg. 20, copied from the memoir in which M. Broca had to contradict M. Pruner-Bey relative to the pretended rickety deformities in the bones of the Eyzies, exhibit the two most common forms. Eickets exhibits its effect on the cranium in a very decided way. It causes the process of ossification to be suspended, and at a later period it accelerates and perverts it. Two absolutely opposite results are produced, the one retarding the evolution of the sutures, the other hastening it. It is evident that rickets sometimes exists during the period of intra-uterine life. All do not allow this, but it is certain that some analogous disorder passes at this period into the bones, traces of which remain during the whole of life. If this condition is cured spontaneously by an acceleration of the process of ossification, like true rickets, we should have in it a simple explanation of a series of cranial deformities depending on the development of the bones, for which the usual theories would not account. The effects of rickets when it unexpectedly comes on Chap, v.] RICKETS OF THE CRANIUM. 169 after tirtli are better understood. Giving warning of its approach before tbe fontanelles and the fibro-cartilaginous laminas -wbich give form to me bones during tbe process of ossification are sufficiently- consolidated, rickets- causes tbem to become soft, lessens their resistance, leaving the cranium to struggle against the continual growth of its contents. Here and there the osseous parietes become thinned and even perforated ; bulgings are formed from the moment that the work has a tendency to begin again, new and independent points of ossification make their appearance, which later on produce the ossa Wormiana. M. Bouvier says, " when the bregmatic fon- tanelle is not closed at two-and-a-half years of age, it is caused by rickets." Should the disease unexpectedly make its appearance at Fig, 20. — Section of tlie tibia at the union of the upper fourth with the lower three-fourths.

Subsequently a cure takes place by a kind of porous or condensed callus, ossification proceeds with undue energy, especially in the serratures, and a condition of things is broiight about in one or several of the sutures which ought only to exist naturally at or beyond 40 years of age — premature synostosis. A loss of balance between the resistance of the parietes of the cranium and the increasing development of its contents is the prin- cipal cause of its pathological deformities. It is sufficient that one of these causes should be at work for the bones and even for the brain to become diseased. The parietes become softened, or at a later period prematurely consolidated, whereas the brain remains sound and goes on increasing naturally; deformity is making its 170 HYDROCEPHALUS. [Chap. T. appearance. If the parietes are passing through, their regular phases of development while hydrocephalus or hypertrophy of the brain is going on, the same result may he produced. The causes of the phenomena are simple while their results are complex. Hydrocephalus, Hydrocephalus is dropsy, or an increased secretion of fluid, in the cranial cavity, whether this fluid has its source in the ventricles or between the membranes. It is acute or chronic, the chronic form being either very serious in amount, moderate, or slight. If the acute form exists to any considerable extent it is speedily fatal. A certain Cardinal, how- ever, lived to be twenty-three {V) years of age ; his head resembled a large ball, and from the base of the forehead to the occiput measured 87 centimetres in circumference. In its moderate and- chronic form it is interesting to the anthropologist in two ways ; either the hydrocephalus comes on shortly after birth, when the sutures offer no obstacle to the distention of the head, and the skull on recovery is easily distinguished by its generally spherical shape ; or it makes its appearance at a later period, when the membranous spaces between the sutures are more or less ossified or serrated, and then the arched projections are more limited in extent, and only appear at certain points. We may also mention, hut with some reserve, a condition of partial hydrocephalus, in which, owing to adhesions between the membranes, the fluid accumulates at particular spots in the form of cysts, or the bones give way, or become altered, as in the preceding case, at some special point. The principal causes of hydrocephalus are the bad constitution of the parents, or hereditary predisposition. Franck mentions the fact of seven infants following, and Goelis of six, being attacked with this disease. Its symptoms are easily recognised : the sutures are wide and very slow in closing; the bones become thinned, ossification is arrested, and a species of local rickets, confined to the cranium, comes on as a complication. General hydrocephalus, which 'comes on after birth, and is sub- Chap, v.] CEREBRAL HTPERTKOPHT. 171 sequently amenable to treatment, is recognised at once by tlie globular form of the cranium. That of the second or third kind is more difficult to diagnose, owing to the existence in both of the following characters : The frontal protuberances are projecting, or rather the whole forehead is so ; the temporal shells present at their centre a rounded arching, or the superior border is detached from the parietal. The supra-occipital region forms an ovoid pro- jection, which communicates with the parietal surfaces by an abrupt inclined plane, in the thick portion of which we see a number of ossa "Wormiana. The retro-mastoid sutures are complicated ; the sagittal and coronal, as well as the union of the greater wings of the sphenoid with the parietal, are thickened, or raised, or interrupted by ossa Wormiana. Frequently a transverse channel, from one surface of the greater wing of the sphenoid to the other, and which is not readily found, passes across the bregma, and seems to divide the cranium into two parts, each of which is increased in size ; the orbital vault is pressed downwards. M. Broca mentions as important signs — when they exist — a primary circumscribed arch- ing at the anterior border of the temporal shell, encroaching upon the adjacent portion of the pterion, and another arching at a point which he calls the dacrion, that is to say at the internal surface of the orbit at the union of the frontal, the ascending process of the maxillary and the os unguis. Hypertrophy. Hypertrophy as well as atrophy of the brain are disorders of development of the substance of that organ, which generally produce their effects upon the parietes of the brain-case. It assumes the form of an acute or chronic, disease, or of a sub-physiological condition, and is frequently induced by excessive work which parents exact from their children before they are fully developed. That which comes on during life or at its close does not concern us here ; that which appears during intra-uterine Hfe, or soon after birth, has a most important influence on the evolution of the cranium. M. BaUlarger has seen a case of hypertrophy in which. 172 PBEMATUEE SYNOSTOSES. [Chap. t. the body weigh.mg 23 kilogrammes, the brain weighed 1160 grammes ; and another in which at four years of age this organ weighed 1305 grammes. Hypertrophy is general, or partial; it affects the whole encephalon, the brain, a single hemisphere, a single lobe, the corpus callosum, or a group of convolutions. The causes which produce it are such as produce hydrocephalus or rickets, and the effects of the three diseases are similar. The inflammation which more particularly causes hypertrophy or hydro- cephalus sometimes passes to the parietes of the cranium through the membranes, producing porous or condensed callus, and an arrest in the ossification of the sutures or their premature oblitera- tion, although the natural effect of each of these maladies is distention of the cranium. Premature Synostoses. Deformities of the most varied description result from all the above-mentioned causes, and from the unequal method in which they exercise their influence upon the sutures. The arrest of the ossification of the sutures is, however, less serious than then pre- mature obliteration. The temporary sutures of intraruterine life, as the interparietal and metopic, persist for an indefinite period with- out resultiug ia any appreciable deformity ; and moreover this per- sistence is regarded by some persons as the probable indication of some disorder in. the new-bom infant. Stahl has seen the- breg- matic fontanelle open in a man of 50 years of age, "but he does not say whether he presented any other peculiarity. The result of an arrest of the ordinary ossification at the edges of the sutures is that there is an increase of the volume of the cranium, which is not sensibly deformed. The effects of premature synostoses are more serious, but they vary according to the period at which they are- produced. Of a gi'ave character when the synostosis takes place in early infancy, their gravity diminishes subsequently, and gradually disappears when the brain has arrived at or near its full term of development. Chap, v.] PREMATURE SYNOSTOSES. 173 M. Vireliow* has attempted to formulate a general law : " At ±lie end of the synostosis of a suture," he says, " the development of the cranium stops short in a direction perpendicular to that of the closed suture " — that is to say, the sagittal suture being closed, the cranium remains narrower and developes in length. His second proposition is that " of aU the parts of the cranium, the hase, and notably the basilar vertebrae, attain the largest amount of development." ; Two other statements of the same author ought to be recorded. Cretinism, according to him, is due to the synostosis of the tri- basilar bone — that is to say, of the spheno-basUar suture and the suture of the body of the anterior sphenoid and the posterior sphenoid. This is why cretins have the occipital shortened, and the base of the nose sunk in. Neither the one nor the other is proved to demonstration. Cruveilhier has refuted by anticipation the explanation given as to microcephalus ; the facts collected by M. Vogt do not establish it, and the specimens in the laboratory of M. Broca contradict it. Let us give some examples of our own. Should the spheno-frontal suture be synostosed, the forehead not having the power to become further enlarged, wiU remain contracted while the rest of the cranium continues to increase. Should the sagittal and coronal sutures be ossified, the lambdoidal and inferior lateral remaining free, the vault at the cranium will become lifted up en masse (acrocephalus), and the increased development wUl be at the expense of the occipital portion. We are acquainted with two examples of this kind. In another cranium we witness the contrary : the sagittal and the lambdoidal are synostosed, and it is the frontal which is driven forwards, the vault of the cranium being at the same time raised. Another cranium exhibits better still what is taking place : all the lateral, posterior, and anterior sutures are welded together, with the exception of the anterior two-thirds of the sagittal, and the internal two-thirds of the coronal on the left side. "What is the result J * 'Virchow, " Geaammelte Abhandlnngen," Frankfort, 1856 ; and " Unter. suchnn^en fiber die Entwiokelung der Sohoedelgrundes," Berlin, 1857. 174 SCAPHOCEPHALTJS. [Chap. t. The anterior and internal half of the left parietal is lifted up ahove •the level of the neighbouring surfaces. It is unnecessary to pro- ceed farther. What we always notice is an iuternal pressure at one point, exerting its influence at the part in the immediate vicinity where it meets with the least resistance, and producing at the flist point an arrest of development, and at others one or more compensatory archings [voussures de compensation). What fre- quently surprises us is to notice a similar synostosis in two different skulls, and one only to he deformed. This depends on the age at Fig, 21. — Scaphocephalic cranium of a Negreas from Senegal. which the lesion is produced. Dr. Thuli6 has presented to the Soci4t6 d'Anthropologie a cranium which possesses considerahle interest in this respect. An accidental hony callus was present on one of the parietals, and had synostosed the sagittal and coronal suture on one side only, notwithstanding which the cranium was perfectly uniform; this, as weU. as other indications, showed that the welding had taken place at 15 or 20 years of age. We must also remember that we are only looking at the external surface of the cranium, and that in certain unaccountable deformities there may exist on %& internal surface incomptete Chap, t.] SCAPHOCEPHALtrS. 176 synostose which escape observation. We will conclude hy giving a classical example of synostosis. Seaphocephalus signifies a deformity peculiar to the cranium, and is characterised by its contraction transversely, its antero- posterior elongation, and its increase in height. The skull turned upside down has the form of a boat, from which its name is derived; the forehead is straight, bulging, and narrow; the occipital is globular and conical, and projects backwards from the lambdoidal suture. An horizontal crest reaches from one to the other on the anterior haK, the sides shelving Uke the roof of a house, which the obliteration of the parietal protuberances renders stiU more prominent. In two specimens presented to the Soci6t6 d'Anthropologie, the length was to the width as 56 : 100 in one, and as 60 : 100 in. the other. These are the faintest cephalic indices hitherto observed on the human cranium. Four opinions are put forward in explanation of this pheno- menon :* (1) According to M. Virchow, it is due to synostosis, during infancy, of the sagittal suture, the other sutures remaining open. (2) According to MM. Minchin and Von Baer, it proceeds from there being but one point of ossification for both parietals — an hypothesis which has but few supporters. (3) According to M. Morselli, there are two distinct parietals, but their two points of ossification are so near together that their fusion quickly takes place. (4) M. Calori thinks that it is the result of an original elongation and narrowness of the cranium. The four may be reduced to two, namely, the fusion of the two parietals and peculiar formation from the first. Mr. Barnard Davis is opposed tO' the former from the fact that in his collection, out of 27 crania with the sagittal suture closed, there are only four scaphocephali. In the laboratory of M. Broca there are many examples of pre- mature obliteration of the sagittal suture, without seaphocephalus. In a Tartar skuU belonging to Mr. Huxley, which is one of the largest known, the sagittal suture is closed, and the others are open. But there is an easy reply to objections : the synostosis of * See " Eevne d'Anthropologife," vol. iii., p. 709 ; " Bnll.

[Chap. v. the sagittal only produces an arrest of development of the vault in a transverse direction and compensatory increase in length, that is to say scaphocephalus, hefore the age of from 8 to 12 years {Br oca). At two years of age its effects are almost inevitable. A case is mentioned in which the deformity existed even at birth. 'So case of scaphocephalus has been published up to the present time in which obliteration of the sagittal had not taken place. Pathological Deformities. Various terms, chiefly of foreign origin, have been employed to designate the principal cranial forms produced by the causes just mentioned. Similar names are given to certain physiological forms which are met with as characteristic of certain races. Here, from the physiological to the morbid condition, as with respect to so many disorders and other affections of the brain, the transition is scarcely perceptible. In how many skulls, looked upon as sound, is there not present this globular supra-iniac projection of the occipital, which is sometimes a characteristic of race, and at others an evidence of hydrocephalus or of premature synostosis] One of the Esquimaux skulls in the museum, regular otherwise, at least in appearance, deserves the epithet of scaphocephalus. The term has been similarly applied to the normal skulls of Austrahans, Polynesians, and African negroes.

Platyceplialio, tapinocephalio, with tte vault of the skuU flattenecl, elliptical. Eviryoephalic, large skull. Stenocephalic, narrow skull. Trochocephalic, very round skull.

Paohyoephalic, skull with thick hypertrophied parietes. Many of these are frequently associated together. Van der HcBven, for example, says that the skulls from the Caroline Archipelago, certaia of the Hebrides, and New Caledonia, are hypsistenocephalic ; Barlow, that a certaia deformed skull found in Silesia is oxykliao- cephalic. As we proceed we shall find other names, equally derived from the Greek, which are more generally in use. There are not only pathological deformities ; there are others with which the anthropologist ought to be acquainted, which he frequently meets with in certain skulls in the course of his cranio- metrical studies, and which he is obliged to put aside. Posthumous, Platylasic, and Plagiocephalic Deformities. The first, or posthumous, is easily recognised. It is produced in more or less moist argillaceous soils by the pressure of the earth which has been exerted upon the softened skull at intervals for ages. The skull is said to have the consistence of soft wax, being variously shaped according to the nature of the soil in which it is enveloped.* One wall might be more or less depressed or sheered round, while the opposite wall might be exactly the reverse. Or the pressure might be local. Sometimes an entire Tjone might be irregularly furrowed. Its principal characteristic is the absence of regularity and symmetry. The second has been called plastic by Mr. B. Davis, a term more conformable mth the preceding, and platybasic by M. Broca. It makes its appearance unexpectedly at aU periods of hfe, but princi- * "Fouillea d'un Cimetiere Bonrgniguon du Cinqui&me Si&cle," by Paul Topinard, in " Bull. Soc. d'Smnlation de I'Ain."

The weight of the head is the immediate cause of it; the articular condyles, the circumference of the occipital foramen, and the adjoining portion of the basilar apophysis becomo Lent, and penetrate into tlic. cranial cavity about one centimiitrc or leas. M. Jdroca considers that it is shown to fixist in white races when the negative angle of Daubenton is more than eight degrees. Tlio third takes place during infancy, but accidentally, cither owing to the infant being constantly carried on the same arm, or by the pressure which the weight of the head fixorts ujjon tho Dutire occipital or upon one side of it when tho infant is lying on its back. In the one case a median flattening, in the other a lateral depression of the whole of the nucha, is prodiiond ; tho skull continuing to dovelope, a compensatory ai'ching (vouamtre d<: com- pensation) is formed on the opposite side, and tlio maximum antero-posterior length of the skull becomes oblique or diagonal.

[Chap. tt. infancy on 130111 sexes, and sometimes on the male only, by very different methods. Sometimes the infant was fastened on a plank, or a sort of cradle with leather straps ; or they applied pieces of clay, pressing them down with small boards on the forehead, the vertex, and the occiput, according to the particular object they had in view. Sometimes the head was kneaded with the hands or the knees, or, the infant being laid on the back, the elbow was pressed on the forehead. Circular bands were sometimes employed to support the sides of the head. Sometimes they had recourse to some other method, which they carried out in another way. Each people, each tribe, each family had its various methods by which they might be recognised. In Vancouver's Island and the neighbour- ing islands, three very different types have been noticed side by side. The infant sometimes dies during the process, and when it sur- vives, it does so to the detriment of the intellectual faculties. The- intellect, however, does not seem generally to be so much affected as we might have supposed. Even the cranial cajjacity is nob diminished, because the brain, if it does not accommodate itself when pressure is forcibly exerted on it, is capable of resisting slow, partial, and progressive pressure. It has been asked whether in the course of time these deformations become hereditary. The ques- tion has generally been answered in the negative, notwithstanding which we would not assert that certain brachycephales did not originate in this way. M. Gosse has described sixteen species of artificial deformation, ten of which were in American skulls, which he afterwards reduces to five. M. Lunier admits seven species.* We shall reduce the most interesting and the most common of them to two, the one dresse, the other eouche, comprising each of the species and the varieties.

Chap, v.] ARTIFICIAL DEFORMATIONS. 181 gradations of form of the most opposite character, and it would be difficult to determine what name to give to them. It is, however, from their being so characteristic, and of forms with which we have become so familiar, that they enable us to recognise the people to which the skull belongs. In the first kind, more or less forcible pressure and counter- pressure, varying also in height and in extent, have been exerted at the two extremities of the skull, thus shortening the antero- posterior and lengthening the vertical and frec^uently the transverse diameter. In the second kind, the length is, on the contrary, increased. Whether the deformations be symmetrical or asymmetrical is imma- terial; sometimes we should expect the latter, but most frequently this would be involuntary and the result of a badly-conducted operation. When in the first kind, the dresse, the most continuous pressure was exerted on a great extent of the occipital, while at the forehead there was only slight counter-pressure, the result was simple occipital deformation, or a vertical occiput. This is observed on the coasts of Peru, among some Puelchas, in one of the tribes of the Vancouver Archipelago, in Malacca, and even in France. If the sides of the skull were at the same time compressed or supported, we should get the quadrangular deformation met with in South America, and among the Paws mentioned by Morton. The pressure on the occipital being increased, and that of the forehead being continued, we should arrive at the raised cuneiform deformation (deformation cuneifonne relevee) of Gosse, which is characteristic of the Nahuas, their descendants the Natchez, certaia of the Chinooks, and, in another part of the world, the Tahitians. The most celebrated variety is the deformation trilohee, iu the form of a trefoU, of the Island of Sacrificios, in the Gulf of Mexico, which is produced by a supplementary band beginning at the occiput, passing up over the median line, and bifurcating in the middle of the sagittal suture to reach the temporal fossae. Things remaining thus, if the frontal pressure is made higher the middle lobe disappears, and we have the cordiform deformity and not the bilobed, because it would become amalgamated with another of which we shall speak presently. 182 ARTIFICIAL DEFORMATIONS. [Chap. v. In the laboratory of M. Brooa there are sixteen beautiful speoimens of this from Ancona, Peru, &c. In the second kind, or couche, the frontal pressure was greater, it being exerted over the whole surface of the bone, while the occipital counter-pressure was exerted lower, was very slight, or none at all (the j)oint d'appui then passed through the vertebral column) ; the skull therefore became elongated behind without obstruction. In the generality of cases, however, a supplementary pressure was made on the vertex. Hence we find on the upper surface of these skulls, from before backwards; (1) a frontal depression or flattening; (2) a bregmatic projection; (3) a post-bregmatic depression; (4) a swel- ling formed by the whole mass of the receding skull. The flattening of the forehead — which is sometimes immoderately receding, as in Fig. 19, representing the Aztecs — took the name, among certain peoples, of deformation of courage (deformation du courage). In the kind termed dresse, the forehead was more frequently widened and more elevated ; in this, it is usually narrower, longer, and lower. One of the consequences of this is that the roof of the orbits is depressed, and that the eyeballs are raised by being made to project There are three species of this deformation or distortion : (1) The cuneiform deformation (deformation cuneiforms coucMe) of Gosse,. which is very marked in the Caribs of the Antilles, the northern Guaranis, and some ]S"orth American tribes near Vancouver's Island. The majority of Chlnooks and other ilat-heads (tetes plates) from the Columbia river, described by Morton, are in the same category. (2) The elongated symmetrical deformation (deformation symetrique allongee) of Morton, in use among the ancient Aymaras. (3) The macrooephalic deformation (deformation mucrocephale) of Europe, which in France has given origin to the annular (annulaire) variety of Foville,* and the bilobed (bilolee) of Lunier — observed in the departments of the Lower Seine and the two Sevres — and to the simple frontal or Toulousian (Toulousaine) variety, so named from the country in which it has been specially noticed. (Fig. 22.) In the annular, the band extends from a point behind the bregma, * See also " La Deformation allongee et cylindrique " of Foville, of which the annular is a variety, in " Anat. Syst. Nerveux " of Foville. Paris, 1844. Chap, v.] DEFORMATION OF THE AYMAEAS. 183 vertically below the chin, by crossing a circular furrow which divides the head into two portions ; these being less decided in the annular than in the bilobed variety. In the Toulousian^ the line starts from the occiput, reaches the forehead obliquely, and there exerts its principal pressure.* The macrocephaUc unites the two systems, so that the frontal depression of the Toulousian and the post-bregmatie depression of the annular exist there, the two being separated by a bregmatic projection. "We must say it is often difficult to distinguish certain macro- eephalic skulls of the Crimea from certain elongated crania from viex Fig. 22. — Artificial deformation of tlie skuil, called Toulousaine. the country of the ancient Aymaras. Among the deformations not included with the two preceding kinds, and which Gosse describes, we may mention the nasal deioTmsAion^diformation nasdle) or flatten- ing of the bones of the nose, practised by the Botocudos of America, and the naso-parietal [deformation naso-parietale) or Mongolian, peculiar to the ancient Huns and to certain Kirghis. "We have said that the types of ethnic deformations of the skull present gradations, whereby they are at times insensibly trans- formed into other types, although their general character remains. * " Snr la Deformation Toulousaine du Cr4ne," by M. Broca, in " Bull. Soc. d'Authrop.," 1871. 184 DEFORMATION OF THE AYMAEAS. [Chap. v. The skulls whicli are met with in Upper Peru and Bolivia, and are generally attributed to the Aymaras, are proofs of this. Their varieties may be reduced to three. In the first, almost the entire skull is thrown backwards, and has the appearance of being recum- bent (couche) horizontally. The most striking example of this which has been under our notice, and which belonged to M. Broca's laboratory, projects 89 millimetres backwards behind the opisthion, while in 20 Europeans', taken at random, the same projection is 68 millimtoes ; but the skull in this species is not always so eoiiche, and we have noticed in others that the sub-occipital region is better supported. In the second species, the most common and most classic among the Aymaras, the sub-occipital counter-pressure is a little higher, and is more perceptible, and the more compact lateral bands, which are readily recognised by their impression, prevent the skull from spreading at the sides. Thus the extremity of the skull which corresponds to the obehon, or to the interval which separates it from the lambda, is conical, and constricted at the base by a circular furrow which starts from the occiput and bifurcates on each side, one portion tending towards the region of the frontal protuberances and the other to the vertex. The varieties of this species differ in the degi-ee of obliquity, above and behind, of the great posterior axis of the skull and of the cone in question. In the most oblique form the recumbent deformation (decoicchee) has become raised. In the example which we have seen lately, the projection behind the opisthion is not more than 58 millimetres, that is to say, it is as much diminished as in the preceding case it was increased. In order to account for the difference in these two cases, we must com- pare together the following measiurements, viz. : their post-opisthiac projection, their maximum vertical projection, and their maximum antero-posterior diameter. The first, which shows the elongation, and the second, the straight character of the skull, are expressed in hundredths of the antero-posterior diameter. In the first example, the index of the projection backwards is ii'Q and that of the height 77-6; and in the second, the one is 34 '3 and the other 92'9. This proves that the deformation gains in horizontal projection in the former case what it loses in vertical in the latter. In the jChap. v.] deformation OF THE NAHUAS. 185 tliird species, which varies as to inclination, all the bands which compressed the sides have disappeared, or at least are scarcely per- ceptible. The lateral furrows are wanting, traces of the frontal pressure alone remain ; the skull is swollen above and behind the auditory foramina, and the whole deformation has the appearance of ■an egg with its larger extremity posteriorly. This most resembles the macrocephalic deformity of the Caucasian skulls. Notwith- standing these varieties, we discover in the three species that a similar method of proceeding has been employed, and for a similar object, which is characteristic of the Aymara race, and which distinguishes it at once from the race of Ancona and also from that of Peru, in which the head is plainly raised up by a flattening from behind forwards. Prom this fact alone we should conclude that the peoples of Ancona belonged to the conquering race, which in Plorida bore the name of Nahuas, and of which the Toltees of Mexico, the Natchez of the Mississippi, and the Totonacks of Sacrificios are other representatives. Conclusion. Our first part being completed thus far, in which we have con- sidered Man zoologically in his ensemble, and having taken special notice of his varieties, it remains for us to give an answer to the question propounded at the close of our preliminary remarks : What place does Man occupy in the class of mammalia 1 Is he to be classified in an order or in a family 1 "We cannot too frequently reiterate that Man, owing to his intellectual powers, occupies the first place in creation, and is its culminating point as a marvel of •organisation ; he therefore exercises upon the planet of which he is an inhabitant a rightful dominion over all living beings. But we must also remember that there does not seem any radical difference between him and those most nearly related to him — the anthropoid apes, Anatomically, they possess the same organs, constructed and arranged in the same way, there being only secondary shades of difference between them. The feet, the hands, the vertebral column, the thorax, the pelvis, the organs of sense — all have the 186 CONCLUSION. [Chap. T. same configuration. The brain also in its structure and its- convolutions is identical. Physiologically, the various functions are exercised in a similar manner ; even their diseases are alike. AH the important differences between them reside in the volume of the brain, which is three times more developed in. Man, and in his faculties, the due adjustment and co-ordination of which give him the judgment, the reason, and the understanding, which are the noblest if not the brightest gems in his crown. An Emeritus professor relates that one day finding himself alone on Mont Blanc, at the halting-place of the Grands Mulcts, he cast his eye over th& depth of the abys& which separated him from Chamounix, and which the Glacier des Bossons rendered impassable. Some intelli- gent guides, however, had discovered a number of invisible paths, which connected these two points, and so assured their communica- tion. Such, said he, is the nature of the abyss which separates Man from animals. The comparison is ingenious, but scarcely correct. The characters which Man and animals possess in common are manifest to all, and no one would have had any doubt on the subject if their serenity had not been disturbed by biblical legends or by philosophical specu- lations. The modes of transition, the anomalies which produce in one that which is normal, in others a strict identity in the majority of the organs, only slightly differing as to form, all indicate that unity of arrangement of which Geoffroy Saint-Hilaire speaks. What should we say if, instead of their being reduced to the human and simian forms which time had bequeathed to us, we had to arrange those which were intermediate, and which had escaped us 1 Whatever his past may have been, Man now appears before us as forming a circumscribed zoological group, to which it is proper to give a name in. our classification. What is it to be ■? In the preceding pages, we have been led to recognise the exist- ence of particular types in each zoological division or subdivision. Eirst, we found a general type proper to all mammalia, that is to say, an ensemble of character common to men and animals, which, whilst distinguishing them collectively, unites them with birds and leptUes, as if all had been formed in one and the same mould, and Chap, t.] CONCLUSIOIf. 187 diversity had supervened subsequently. Then, laying aside that "which is foreigjn to our purpose, a general type common to all the monkey trihe, and to which Man assimilates infinitely more than to that of the camivori or ruminants. Lastly, in this simian group we found a succession of dissimilar types : first, that of lemurs, but slightly homogeneous, ill-defined, and showing a preference on the one side to certain cheiroptera and insectivora, and on the other to some species of cebians, or monkeys of the new continent ; a second type, better defined and brought to greater perfection ; then a third type, that of pithecians, or monkeys of the old continent, divorcing itself from the second, and in which the particular traces of resemblance to Man are more apparent. Up to this point, the three simian types follow each other in a regular gradation of succession. But after the third there is a bound ; the pithecians have less resemblance to the anthropoid apes than to the cebians. The general type of the anthropoids is indeed altogether difierent and very marked, but it bears the closest resemblance to that of Man. The conclusions we formed at each step were, that many a characteristic so similar in monkeys of the three inferior groups, and iu quadrupeds, is different ia the anthro- poid ; and the physiognomy assumes a resemblance to that which it presents in Man. In a word, the type of character changes as we pass from the pithecians to the anthropoids ; their degree or their quantity alone varying as we pass from the anthropoids to Man. The real differences between these last may be reduced to two, which are not of equal value : (1) Man always stands erect. The anthropoid ape sometimes holds himself erect and sometimes goes on all-fours ; and in the latter case he makes use of his anterior extremities as hands — as we should do in that attitude — and hot as feet. The variations in their respective skeletons, muscles, viscera, as well as their direction of vision, depend on it. (2) The brain of Man is three times as large ; hence the development of his intellectual faculties, of his faculty of language, and of his facial angle. Apart from these two points, and from everything which they involve, we can only discover resemblances between Man and the 188 CONCLUSION, [Chap. t. anthropoids, and the following question naturally arises : Among the four classes of anthropoids, is there one more than another which approaches to Man t The gibhon may be set aside. In respect to his cerebral con- volutions and the vertebral column, taken as a whole he is really superior ; but as regards the proportions of his extremities, the narrowness of his pelvis, the arrangement of his muscles, the callosities on his buttocks, and his habits of living, he establishes the, transition to the pithecians. The orang occupies an equally unfavourable position, by reason of certain anatomical characteristics which are proper to him, by the proportions of his skeleton, and by his defective feet and hands; but he recovers it owing to his cerebral convolutions, his facial angle, the number of his ribs, his teeth, and perhaps also his intelligence. The chimpanzee is remarkable for the richness of his cerebral convolutions, the proportions of his skeleton, the disposition of his femurs, and the general physiognomy of his skull. Lastly, the gorilla has the volume of his braiu in his favour ; the direction of his vision, his height, the general proportion of his limbs, the arrangement of his muscles, his hand, his foot, and his pelvis ; but he has thirteen pairs of ribs, a defective vertebral column, laryngeal sacs, a diastema, and very large canines. For our part we rather decide in favour of the chimpanzee, and particularly of certain of his species ; but it is necessary that these should be better known. The elements upon which the leading arrangement of the zoological divisions should be based are: (1) a general type, common to all the mammalia; (2) a general sub-type, common to all monkeys proper, to the anthropoid, and to Man; (3) a particular type, common to these last two ; (4) the human type. The most strilting fact in relation to this was brought forward at a remarkable discussion which took place in 1869, at a meeting of the Society d' Anthro- pologic. The question of doctrine having been carefully avoided, the conclusion was arrived at that the anthropoid apes mare nearly approach Man anatomically than the monkeys next in order to tliem. Chap, t.] CONCLUSION. 189 Consequently the separation to be made at the extreme of the series, hetween the inferior monkeys and Man, cannot be logically placed between the anthropoid and the so-called common monkeys. This leads us to Mr. Huxley's classification: (1) Man and the anthropoid apes ; (2) the monkeys of the old and new continents ; (3) lemurs. But we must necessarily draw a strong line of demarcation between Man and the anthropoids. Although the type common to both differs only in degree, that which concerns the brain has so considerable a range that division becomes inevitable. But, to be logical^ we must in the same way separate the monkeys of the old continent from those of the new, which have an equal claim to differ by reason of other characteristics ; and this leads us definitely to adopt the classification of M. Broca : (1) Man ; (2) the anthropoid apes; (3) pithecians ; (4) cebians; (5) lemurs. J^ow these five groups have nearly the same zoological value, and are separated from each other by equal intervals. United, they present an ensemile of common features, which separates them en masse from the camivora as much as these are separated from the marsupialia or the cetaoea. We must then give to each of them equivalent leading titles, and to the whole collectively a title similar to that of camivora, of marsupialia, or cetacea. They thus form five families in one and the same order — that of Primates. Consequently, Man forms one FAMILY ; the first in the OEDEE of Primates, the first iu the CLASS of MammaKa. It remains for us to inquire whether the divisions of this family are to be arranged as genera, as species, or as varieties. We shall decide this question after having examined the elements of the problem in our second part. PAET II. ■OF THE EACES OF MANKIND. CHAPTEK I.

The divisions and subdivisions of the iiuman family are designated in current language by the name of races ; and as such their study would not present greater difficulties than that of aU other analo- gous divisions of natural history, but for the intrusion of questions of doctrine. Have these races the value of species, of varieties, or even of genera ? This is the question. Before giving a reply we must pass in review: (1) the accepted definitions of all these terms ; (2) the classification of races ; (3) the particular characteristics upon which they rest ; (4) the principal physical types which we may take for granted exist among mankind in general Of Species. The main point of the dispute lies in the sense attached to this word, and to its exact limitation; which necessitates our bringing in a certain number of definitions, and these have the advantage of drawing the questions closer together. In determining the first series of defijiitions we shall be met at the very threshold mth inherent difficulties. In the second is sketched out a principle pregnant with consequences — species are variable, without any 194 SPECIES. [Chap. i. precise limits, and become transformed in the course of time. In the last the contrary principle is maintained, namely, that species are immutable, and changes in them never pass beyond certain boundaries. "Under the denomination of species," Eobinet -writes ia 1768, " naturaUsts embrace the aggregate of individuals which possess an amount of appreciable difference." " Species," says Agassiz, " is the last division of classification at which naturalists pause ; and this division is based upon the least important characteristics, such as form, c olour , and propor- tions." " Species," according to Lamarck, " is the aggregate of iudi- viduals Kke each other, whose offspring is perpetuated in the same condition, as long as circumstances of situation are not changed to such a degree as to alter their habits, their disposition, and their forms." "Species," says Geoffroy Saint -Hilaire subsequently, "is an aggregation or succession of individuals characterised by a uniformity of distinctive features, whose transmission is natural, regular, and unlimited in the present state of things." " Species," says Cuvier, " is the aggregate of all organised beings, descended from one original parentage, or from those which resemble them as far as they resemble each other." In the following definition of Prichard, in which especial refer- ence is made to the position assigned to Man, we perceive the dominance of orthodox ideas, and, at the same time, some amount of vagueness attributable to the influence of Lamarck. " Species," he remarks, " is an aggregate of individuals resembling each other, whose slight differences are explained by the influence of physical agencies, and who are descended from a primitive pair." This is the ancient monogenestie creed. M. de Quatrefages considers that the elements of the definition may be reduced to two, viz. : " the resemblance of individuals to each other, and their uninterrupted descent from a primitive group." It is not until subsequently that he admits, as a practical criterion of species, the result of inbreeding. " Individuals of the Chap, i.] SPECIES. 195 same species," he remarks, " are alone capable of producing prolific offspring." This idea is precisely that of the old botanists Eay and De Candolle. What are we to think of these divergences ? That species might really he nothing more than one of those " products of art " of -which Lamarck speaks, and not a definite and absolute zoological association. Its most zealous partisans declare that it has but one criterion by which it may be recognised— the fecundity of individuals inter se, and their sterility with those of contiguous species. But this criterion has undergone many assaults of late years. Many species, admitted incontestably to be diverse from one another, have produced prolific offspring, unquestionably very proHfic. Naturalists generally denied it at first, and held to the denial with pertinacious grasp, declaring that they were deceived, and that the pretended species were simply varieties. Be it so. The hare and the rabbit, the dog and the wolf, the camel and the dromedary are of the same species. But the distance between the goat and the sheep is greater ; they are genera, and by descending only one step they would only become species. Now their cross- breeds succeed weU. in Chili. The wild goat and the domestic goat are also different genera ; nevertheless, in the Pyrenees they produce mixed breeds, which have been described by Count de Bouill^ It appears that even the union of a heifer and a stag produced a hybrid, which was exhibited at an agricultural meeting in the department of Aisne. But it is not suf&cient that there should be a cross-breed and progeny ; the criterion of species is that this progeny itself and its descendants should be fertile, and that the mongrels left to them- selves should never revert either to the paternal or maternal type. However, this is only one step in the mode of manifestation of an organic property, which we shall describe later on under the name of homogenesis, and which is the faculty that two germs of opposite sexes possess in different individuals of becoming reciprocally prolific, however great their zoological distance may be. Simple fecundity is the first step. The union of the hare and the rabbit furnishes an example of the most advanced step. The different species produce offspring of an intermediate character, termed o 2 196 VABIETY. [Chap. i. leporides, wliich. after twenty generations are still fixed, after repeated experiments both in France and Germany. The perpetuity of the type of species is secured, under these circumstances, by the faculty of individuals to intercross more successfully and to produce offspring, which in their turn continue to propagate those resembling themselves. ISTo one disputes this. It is equally the rule that crossings outside the species are sterile, but in both cases there are exceptions which do not confirm the rule, and which increase iu number the more closely we look at the matter ; exceptions which, reasoning by analogy, could not be fore- seen, and which are only learnt from experience. This more or less potent affinity between genera and species, and the more or less favoured varieties of mongrels resulting in consequence, prove at least that the barriers of species are not inviolable, and that the pre- tended criterion has nothing positive about it. Later on, when we are considering the degree of homogenesis of races in human cross-breeds, we must beware of gathering from them an argument either for or against their quality of species or variety. Of Variety. Under this name, devoid of all qualification, we usually under- stand an assemblage of individuals presenting common character- istics, and thereby distinguished from contiguous groups having other common characteristics, or those of a more general type. It is transient and accidental, or permanent. Teratological variety, and variety the resrdt of the influence of external conditions, belong to the former. Apropos of the permanent variety, aU kinds of difference of doctrine are observable. In the transformation schools of the present day no distinction is made between them and species. In the opposite school of olden time, that of Prichard for example, the two so far approach each other that their character- istics are altogether hereditary ; but whilst the permanent variety is merely an accidental one which is fixed and determined, species had always existed, or at least had descended from a single pair. Chap, i.] EACE. 1S7 Of Race. The word has many acceptations, according to the particular doctrine embraced or the absence of doctrine. In the one case it corresponds to the permanent and secondary variety of Prichard, ia the other it expresses so well-marked a zoological limit, that one is compelled to ask whether it is not confounded with species. Jn current language indeed it has a vague meaning, leaving all. the questions svh judice. "Eaces are hereditary varieties," remarks Adrien de Jussieu; and M. de Quatrefages says : "When the accidental characteristics "which distinguish a vegetable or an animal variety are transmitted by generation and become hereditary, then we have a race." " Zoologists and botanists are imanimous on this point," he goes on to say ; and further : " The race is the ensemMe of individuals like each other, belonging to one and the same species, having received and transmitted by generation the characteristics of a primitive variety." Does M. de Quatrefages mean to say that it is quite primitive ; for, the disputed criterion of fecundity being set aside, how are we to distinguish primitive variety from species? The accidental origin is pointed out precisely in this other definition. " Eace," says Isidore Geoffroy Saint-HUaire, " is a succession of individuals springing from one another, and rendered distinct by undeviating characteristics."* M. G. Pouchet gives the word another acceptation, which is that of the ancient polygenists : " The word ' race ' designates the different natural groups of mankind." According to him they are so many species. There is q, radical difference between this and admitting that certain races represent species, but that others are only per- manent varieties, f * " Eevue des Cours Soientif., 1867-68 ;" " Lemons " of M. de Quatrefages, •' Hiatoire Nat.

Paris, 1864. 198 CLASSIFICATION OF RACES. [Chap. i. Another way in wliicli the word " race " is understood, or rather employed, is that set forth la the following definition of Prichard : " Under the name of races we include all assemblages of iadividuals presentiag viore or less common characteristics, transmissible by succession, the origin of these characteristics being an unsettled question. " The term may thus be used iadifferently and taken in its widest sense. It applies as well to more or less thoroughly- defined human varieties, or sub-varieties, as to species. Under its shadow every variety of opinion may recline ; negroes in general may be looked upon as a race in the same way as Kaffirs or natives of the Gold Coast. "We shall speak as a matter of convenience of pme, cross, mixed, primary, and secondary races. There will be anthropological and historical races, as well as those determined according to language. Some are lost ia obscurity, and will only be found by a diligent examination of every possible species of evidence; others wUl be seen under our very eyes, as the living races of Australia and America. At the moment when we ought to decide as to the number and value of races, we shall come to an orderly arrangement inspired by the teachings of our master, M. Broca, who says, " The varieties of mankind have received the name of races, which gives the idea of a more or less direct relationship between iadividuals of the same variety, but does not decide either affirmatively or negatively the question of the relationship between individuals of different varieties." * Eaces thus included, that is to say, the more or less generally accepted divisions and subdivisions of the human family, are well- nigh infinite ; we are compelled therefore to group them. Those of the most striking character we place first ; then those which are less and less determined ; and, lastly, those which we make a guess at, or which are to be discovered by the help of geography, history, and linguistics. Classification of Eaces. The first attempt at classification was made in the year 1772, liy F. Bemier, a French traveller, who made out that there were * Article " Anthropologie," in " Diet. Bnoyol. des Sciences Me'dicales," vol. v. Chap, i.]; CLASSIfflOATION OF BACKS. 199 four races : the -white in Europe, the yellow in Asia, the black ia Africa, and Laplanders ia the north. The second -was that of Linnseus. His genus Man iacludes three species : homo sapiens, homo ferus, and homo monstruosm. His savage man is dumb, covered with hair, and walks on all-fours. Among his mansfrous men he iacludes the microcephales and the plagiocephales. His homo sapiens includes four varieties : the European, with flaxen hair, blue eyes, and light skia ; the Asiatic, with blackish hair, brown eyes, and yellowish skia ; the African, with black wooUy hair, black skia, flat nose, and thick lips ; and the American, with tawny skia, long black hair, and beardless chia. Buffon did not classify — ^he described. He recognised more particularly a northern race, a Malay race, and made a distinc- tion between Hottentots and other African negroes. The first classification which possessed a certain amount of prestige was that of Blumenbach. The Gdttiagen professor described five human varieties : the Caucasian, the Mongolian, the Ethiopian, the American, and the Malay. He was the origiaator of the title of Caucasian, which is now ia use, and which he employed because the Caucasus is near Mount Ararat, upon which the ark rested after the flood. But a period soon arrived when a reaction took place among a certain number of naturalists. Three pairs alone having survived the universal deluge, as a matter of course all the races of mankind now living upon the earth descended from them. CJuvier admits three races — the white, or Caucasian, the Mongo- lian, and the negro. D&ormais divides the first into three — the Indo-Pelasgian, the Armenian (Semitic), and the Scytho-Tartarian ; and includes in the second the Kalmucks, the Mantchiis, the Chinese, the Japanese, the Coreans, and the inhabitants of Micro- nesia (the Marianne and Caroline Isles). He does not speak of the divisions of the negro race ; but, not knowing where to find a place in his classification for the Malays, Papuans, Lapps, Esqui- maux, and Americans, he rejects them altogether from his category. " The red colour of the Indians of America," however, he does "not consider sufficient ground for placing them in a distiact race." 200 CLASSIFICATION OF RACES. [Chap. i. The authority of Blumenbach, however, counterbalanced that of Cuvier, and classic authors, with some dissentients, divided them between the five races of the one and the three races of the other, liac^pfede, Prichard, Jacquinot, and Flourens were in favour of three, the last-named recognising about thirty-three different types. The first opposition came from Virey, in 1801, who gave out tiiat the human family was composed of two species, the white and the black, each being divided into six races, and these in their turn into families. Bory de Saint- Vincent and A. Desmoulins were of the same opinion. The former, taking up the propositions of La Peyr^re, declared that Adam was " the father of the Jews only, and that the differences between the human races are sufficiently great to merit the designation of species." He admitted fifteen, many of which in their turn included many races, namely, the Japhetic or European, the Arabian, the Hindoo, the Scythian (Turks), the Sinican (Chinese), the Hyperborean, the Neptunian (Malays, Polynesians, and Papons), the Australian, the Columbian and American, the Ethiopian, the Kaffir, the Melanesian, and the Hottentot. Among the secondary races a few deserve to be mentioned : the Arabian species, comprising the Adamic Jews and Arabians, and the Atlantic race (Berbers). A. Desmoulins at the same time as, or rather before, Bory de Saint-Vincent, raised the number of human species to sixteen. He mentions two which had escaped Bory, namely, the Kurilian and the Papuan. The Caucasian species is taken in a different acceptation to that of Blumenbach and Cuvier; it merely desig- nates a particular group of the Caucasus, including the Mingrelians, the Georgians, and the Armenians.

We see that the frontal region is larger in the Parisians than in the Basques, and less in the negroes. It appears a priori that the face of Parisians is larger, but it must be remembered that the face ia the negro is developed in length, which, instead of increasing, diminishes the angle.* The angle of prognathism has been already described. There are besides : (a) The metafacial angle of Serres, which the pterygoid processes form with the base of the skull. It seems to us to vary with the prognathism, but not very much.

But ■when we take the various ages into consideration matters present themselves in a different light. The sphenoidal angle is relatively a little larger in infancy than in adult age, and notably smaller in monkeys, which is in accordance with M. Welcker's statement that in Man the cerebral ca^vity at birth is less, relatively to its maximum volume, than at full age,* but that this ca^Tity grows much more rapidly (see page 131). It has been asked what relation there is between the sphenoidal angle, that is to say the straight and curved portion of the body of the cranial vertebrse, and prognathism. M. Yirchow asserts that it diminishes when the latter increases. M. Welcker says the reverse. M. Lucse considers that they have no relation to each other. The same comparison has been made with the naso-basal angle, but improperly so, this only measuring a very small part of prognathism, and that the least important part, which we have called the nasal or supra-maxillary. * " Memoire sixr les Microoephales," by Carl Vogt. Geneva, 1867. 294 ANGLE OF THE CONDYLES. [Chap, hi, Tlie sphenoidal angle is very objectionable, inasmuch, as it can only be measured on a section, and necessitates the skull being divided, M. Broca has, to a certaia extent, met the objection by his proceeding with the sphenoidal crochet, shown at Kg. 37, and one wliich he has recently successfully carried out.* Under the rather inapt title of the angle of the condyles, M. Eoker understands the obtuse angle, open above and behind, that the plane of the occipital foramen forms with the plane of the basilar groove, or clivus.t It varies from 100 to 125 degrees in negroes, and from 117 to 140 in whites; the mean being 113-5 in the former, and 128-2 in the latter. The difference, therefore, is so remarkable that this measure- ment ought to be maintained. It arises, according to the author, from the fact that the plane of the occipital foramen is lowered at its anterior border, as M. Broca . has shown by the help of his occipital angles. But the strange part of it is — and it is not the first time that we have met with things of this kind — that this angle in anthropoids more nearly approaches that of the white than that of the black. It was 120 degrees in a young orang, 122 in a gorilla, and 128 in an old orang. Its diminution in negroes is not due, therefore, to the lowering of the occipital foramen, inasmuch as the latter is lower still in anthropoids. The variations of the angle of Eoker are depend i^-s-t then on the inchnation of the basilar groove. Special Systems. Under the title of special systems several topics might be con- sidered which have not been noticed in the foregoing chapters. We shall only mention two of them — endometry and endoscopy.

The cranial net of M. Welcker, a system of triangulation of the external surface of the cranial ovoid, exclusive of the face, has not given results worthy of being recorded. It consists of — (a) A superior cranial quadrilateral, included between the parietal and frontal pro- tuberances ; (b) A frontal quadrilateral, smaller, included between the frontal protuberances and the line uniting the external orbital processes of the frontal; (c) An inferior quadrilateral, the anterior side of which is formed by that line, and the posterior by the line going from the point of one mastoid process to the other ; (d) A triangle having this latter line for a base, and the inion for its apex. A triangle with its apex stiU at the inion, but its base on the line of the two parietal protuberances, terminates the circle of the figures in pairs. Two quadrilateral and two lateral triangles complete the entire system. It is useless to proceed farther. The system of Iheriag is applied to the method of projections. 296 SYSTEMS OF ANTBLME AND KOPEENICKI. [Chap. iii. The author seems to have had a strong feeling against the doctrine of Oken on the vertebral constitution of the cranium, and in favour of that of Gegenbauer, maintaining that the cranium is formed in a manner independently of the vertebral column. There are no anatomical points, he says, upon which one can rely ; that it is useless to search for the relations of the different portions of the cranium ; and that it can only be measured as a whole, with the aid of maximum, and reciprocally perpendicular, lines. M. Ihering has consequently invented an apparatus for taking these maxima of height, breadth, and length, the skull being in its natural attitude. But here M. Ihering sets the rule he has laid down at defiance, and has recourse to anatomical points. In order to place the skull in proper position, he adopts, as a fundamental line, the line of Meckel, going from the centre of the auditory meatus to the inferior border of the orbit. Now this line, by which everyone is guided, is raised eight degrees in relation to the axis of the orbital cavities, or to that of vision, in order to give the skull the most appropriate attitude. In the norma verticalis, to which it gives rise, the most prognathous skuUs become orthog- nathous. Moreover, M. Ihering has partly given up his system : in the table of measurements which he propounded at the Dresden Congress in 1874 he becomes quite eclectic. The system of Antelme allows, with the aid of a special cephalometer, which is unfortunately very costly, of our determining with great exactness the reciprocal position of all the external points of the skull, and the distance from these points to the centre of the biauricular axis. Designed for use on the living subject, M. Bartillon has modified it so as to adapt it to the skull. For his description of it we refer the reader to the first volume of the " Memoires de la Society d' Anthropologic," and for examples of its application to the memoir of M. Bartillon on New Cale- donians, in the "Eevue d' Anthropologic," vol. i. p. 284, 1872. The system of M. Kopernigki also requires a particular cranio- graph, which must have been suggested by the physionotype of Huschke, and reminds one of the circular band used by hatters. Its object is, among others, to take measurements of the skull Phap. IV.] OSTEOMETBICAL CHAEACTERS. 297 which, have heeii omitted by other methods of procedure. For a description of it we refer the reader to, the " Bulletins de la Sooi^td d'Anthropologie," 2nd series, vol. ii., 1867 ; and for its appK- eation, to the memoir on Bulgarian skulls by M. J. Kopernifki, in the "Eevue d'Anthropologie," vol. iv. p. 68, 1875. To sum up : the craniometer substitutes mathematical data for the uncertain data founded on judgment and opinion. It studies the skeleton of the head in its ejisemble, the cranium and the face separately, and then each of its parts, by methods which take the head in its natural attitude, accept certain central points of more or less physiological importance, or have to do directly with absolute measurements apart from all preconceived theory. One of its systems is specially fertile in good results, namely, the com- parison of methods under the form of indices ; but it requires a l-arge number of skulls in which individual marks of variation are effaced. Characteristics hitherto left to chance investigation also come within its province. It shows that the eye may be deceived, and analyses as far as possible those variable impressions which we term the beautiful. Although at first, and even now, encumbered with materials many of which ought to be eliminated, it has enabled us to recognise human types which without it would have remained undetermined ; and it bids fair ene day to furnish a solid basis for the classification of races into genera and species.

The other parts of the skeleton have been less studied than the skull : in the first place because their importance ,was not under- stood; and in the second, because travellers and archiEologists neglected to take account of them. The characters which they furnish are of two orders, some having reference to the configuration 298 PERFORATION OF THE HUMERTJS. [Chap. iv. of the bones themselves, and others to their respective proportions. Among the former may be placed the perforation of the humerus, certain forms of the femur, the tibia, the fibula, and the ulna ; the torsion of the humerus and the femur ; the curvature of the latter ; the angle which its body makes with the diaphysis ; the projection of the calcaneum ; the breadth of the olecranon, &c. "We shall only refer to some of these. The perforation of the olecranon cavity of the humerus, first noticed in some skeletons of Hottentots and Guanches, is also met with in the negro and European. Its degree of frequency among the races of France has been the subject of discussion of late, and it is asked whether this character did not specially belong to one of the most ancient. The subjoined table wlU. in a measure solve this question. "We are indebted to the kindness of Dr. Pruni^res de Marvejols, to whom anthropology owes so much for his many valuable discoveries, for aU that we know respecting La Lozfere. The results at the Pre-gallic station of Campans emanate from MM. Broca and Millecamps ; those on Parisians of the fourth to the tenth century, and on the mountaineers of the Ain, from ourselves. The others have been specially published in a note in the "M^moires" by M. Broca, vol. ii. p. 366.

Its excessive rarity ia the hurial-places of individuals of the higher ranks at Chelles seems to account for this diminution. The following list of the variations at simUar stations of the same epoch shows, however, that we must accept the ahove with some reserve. It has reference to the dolmens separately noticed by M. Prunieres de Marvejols.

Brooa, that it is more particularly to be seen in women. The character which the tibia sometimes presents, and which bears the name of platycnemia, or sabre-like, is much more remarkable. This bone is described in aU works on anatomy as having a prismatic or triangular diaphysis. Its anterior border, immediately under the skin, is termed the crest of the tibia ; its internal gives insertion to an aponeurosis, which is applied to the fibula, and separates the muscles of the anterior region of the leg from those of the posterior. Its posterior surface is traversed above by an oblique rough line, which serves for the insertion of the popliteus muscle ; and below by a longitudinal line, giving insertion to other adjoining muscles. In platycnemia, the tibia has only two surfaces in its three upper fifths, an external and an internal. The anterior border is thin, the internal and external borders occupy the centre of the two surfaces, and the new posterior border corresponds to the above Unes of insertion of muscles. Figure 38 shows a section of the two sorts of tibia. Platycnemia is noticed here and there in many of our graves, but with variable frequency. The first time 300 F:6muR 1 COLONNE. [Chap. iv. it was observed was in the tibias of the family buried at Cro- Magnon, at the Ancient Stone period. It has frequently been de- scribed as existing in England, both at the Pre-gallic and the Polished Stone periods. In 200 Parisian tibias, which we have collected from the St. Marcel and St. Germain-des-Pr& cemeteries, dating from the fourth to the tenth century, 5 '25 per cent, were platycnemic, and 14 per cent, were bent. This latter pecu- liarity is not uncommon in old graves, as well as the channelled fibula, that is to say, the fibula with enormously large longitudinal grooves for the insertion of muscles, the ulna incurvated forwards in its upper fourth, and the femur a colonnc. This last is worthy a separate description. H.i . Fig. 38, — No. 1, Ordinary triangular tibia, the diaphysis divided on a level with the nutritive foramen. No. 2, Platycnemic tibia divided at the same spot. The muscles of the posterior part of the thigh are principally attached to the two longitudinal lines which form the posterior border of the femur, and together bear the name of linea aspera {ligne dpre). These two lines are wanting in the anthropoid ape, the border being round. In Man they are either blended together BO as to be scarcely visible, or they project, and are .separated by a rough interval. In the femur a colonna they form a still greater projection ; they are wider apart, and the adjoining surfaces of the bone being sunk in, make this projection appear still greater. Hence their pilaster-like appearance extending along the middle three-fifths of the bone. The femurs of Cro-Magnon are the most striking examples of this, those of the Guanches, in the laboratory of M. Broca, are very similar. Of 200 Parisian femurs obtained Chap, iv.] OSTEOMETEICAL CHARACTERS. 301 from the cemeteries before referred to, in 6-5 per cent, the column was very marked, and in 36 per cent, it was so slightly. It seems, therefore, that these peculiarities of the tibia, femur, and fibula be- longed to one and the same race in Western Europe. The 30 subjects from the cave at Sordes, in the Basque territory, belonging to the Polished Stone period, all exhibit them {Hamy). It is very remarkable, however, that they are rarely met with having per- foration of the olecranon cavity. The two races which have be- queathed to us the two varieties are therefore distinct. "We have observed platycnemia, the incuivated ulna, and the pillar-like femur in other races, notably in skeletons from Oceania. The complete obliteration of the linea aspera of the femur, one of the highest simian characteristics, is rare. It is observed in the skeleton of the Hottentot Venus, now in Paris. Osteometrical Cliaracters. At page 81 we have shown the difficulties met with in at once determining the proportions of the body on the skeleton and on the living subject, and the two methods which are in favour with anatomists — one in which the length of the bones is compared with the stature of the individual, the other in which the bones are com- pared with each other. We have also given the general results arrived at on a comparison of Man and the anthropoids. It now remains for us to speak of the appreciable differences between races : first, of those which we notice directly on the skeleton; and then of those which are to be studied on the living subject. The selection of osteometrical measurements and methods of proceeding varies according to the object we have in view. When we wish to calculate the proportions of the body, we are obliged to measure the bones in their normal position, the individual being supposed to be standing erect, and only to include that portion which contributes to the total length of the limb. At other times we are satisfied with their absolute length. For some, as the clavicle, the fibula, and even the ulna, this is generally sulficient. The bone is laid upon a graduated slab — ^the osteometrical slab of M. Broca 302 OSTBOMETfllCAL CHAEACTEES. [Chap. it. being preferred — and with a sqiiare we take the two most deviating projections which it gives on this slab. Such is the usual mode of proceeding. With the radius we do the same, having no choice in the matter. The forearm really extends no farther than the convex articular surface of the carpus, and consequently the articular cavity corresponding to the inferior extremity of the radius ; but no spot on the circumference of this cavity furnishes any fixed measur- ing point, so that we are obliged to include the styloid process in. the length of the bone, consoling ourselves that the measurement becomes easier to compare with that taken on the living subject. In the humerus the natural obliquity of the bone is so slight that we may leave it out of consideration, and we have no hesitation as to the measuring points, except as regards its inferior extremity. White measured the humerus from the border of the acromion to the point of the olecranon. M. Hamy, when engaged on the subject of the development of the bone, and looking for its maxi- mum, took the internal border of the trochlea. M. Broca, wishing to join the humerus to the radius, makes the former terminate at iheir point of contact, at the condyle. In the tibia the superior limit is, without doubt, the flat articular surface ; while the inferior, if we require the true length of the leg, is the cavity articulating with the astragalus, and in practice one .of the borders of this cavity ; we therefore do not include the internal malleolus, which is like a supplementary bone. It certainly is not rational, when the propor- tions of the limbs are in question, to include the internal malleolus with the leg, at the same time that we discard the styloid process from the forearm ; but in this latter case necessity makes the law. The femur is the long bone, in which our methods of proceeding necessarily vary according to the object we have in view. If we want its length in proportion to the height of the body, we must take account of its obliquity. Por this purpose the bone is placed on its posterior surface, so that the two condyles are square with the vertical plane. The regular position of the bone on the living subject is thus obtained ; and it only remains to determine, with the square, its superior maximum, whether at the top of its head or at the point of the great trochanter — the former being the better for Chap, it.] PEOPOKTIONS OF THE SKELETON. 303 getting at the general proportions. If, on the contrary, the ahsolute length is required, inclusively or exclusively of the great trochanter, Tve begin, as with the clavicle, by laying the bone on the outer side. Proportions of the Skeleton. "White, as far back as the year 1794, remarked in the living subject, and demonstrated both on this and on the skeleton, that the forearm of the negro, compared ■with the arm, is longer than that of the European ; but not going into the matter further, nothing ■was done up to the time of La-wrence iu 1817. Humphry, iu 1838, ■was more explicit. He stated that the thigh and the arm of the negro are shorter than those of the ■white, ■whUe his superior extremity is longer ; that there is but little differ- ence bet"ween his arm and forearm ; that his leg is of the same length, but longer as compared -with the thigh ; and that his hand is an eighth, and his foot a t^welfth, shorter.

Let us then take M. Brooa's figures. In the follo^wiug table the absolute lengths are ■compared together and added. We dra^w attention particularly to the first three relations : Htonerns + radius : femnr + tibia = 100.. Eadi-as : humemB = 100 ... Radius : femur + tibia = 100 Humerus : femur + tibia = 100 ...

[Chap. it. in proportion to the humerus. (&) That his anterior extremity, from the shoulder to the -wrist, is a little shorter, which is an anomaly, when we remember that it is longer in the anthropoid ; however, it may probably be explained, (c) That his radius is perceptibly longer in proportion to the humerus, thus approximating it to that of the ape ; White, Humphry, and Broca are all agreed in this respect, (d) That his tibia is longer as compared with the femur, which, if our statement at page 88 is confirmed, would make it less simian than the European, (e) Lastly, that his humerus is shorter, and this no doubt explains the above anomaly. The upper extremity of the negro is shorter than that of the European, not because liis radius has been lengthened, but because his humerus has been shortened. A superior character has originated from the union of two inferior ones. The anomaly in M. Eroea's table is perhaps accidental — Mr. Humphry's figures giving the rela- tion to the height of the body, lead us to think so — it loses all its importance when, considering the diversity of races, we see the un- important position which the proportions of the skeleton exhibit in the series. The following are some relations calculated according to M. Broca's mode after measurements made by Barnard Davis,* Humphry, Broca, and ourselves : Hum. + rad.: fera.+ tib. Ead.: hum.

It is true the Esquimau and the Andaman have th& * " On the Osteology and PecuUaritiea of the Tasmanians," by J. Barnard Davis. Harlem, 1874.

By far the longest radius is seen in the Javanese and Tasmanians, and the shortest in the Esquimau, -while the Europeans are intermediate in length. The tibia appears to he decidedly the longest in the inferior races, and shortest in the Esquimau and the Aino. As regards the tihia, therefore, the balance is in favour of Mr. Humphry's views, and contrary to the foregoing calculations. It is clear thus far, without one's being able to account for it on any definite principle, that the proportions of Man neither approxi- mate to, nor are far removed from, those of the anthropoid in all parts of the skeleton at once, but sometimes in one and sometimes in another. ISTothing is more opposed to the monogenistic theory of hierarchical gradation of races, and more conformable to that of parallel formations. A type is superior in one point, inferior in another. It is the same with the family of the anthropoids, there is the same divergence of proportions between their genera and species as between the human races.* The proportions of the trunk, with the exception of the pelvis, can hardly be studied except on the living subject. The Pelvis. The pelvis, formed by the two Uiac bones and the sacrum, is divided into two parts — the great pelvis, or wide upper portion, and the small pelvis, or pelvic cavity, through which the foetus passes at birth. Camper and Soemmering observed that the pelvis of the negro in its ensemble is narrower than that of the white. Cuvier, in his brUliant memoir on the Hottentot Venus, insisted on the evidences of inferiority which he found in it. Weber maintained * See " Memoires," by M. Broca, already referred to, page 86 ; "A Treatise on the Hmnan Skeleton," by Humphry, Cambridge, 1858 ; " Eeoherohes snr les Proportions du Bras et de I'Avant-bras," by E.

[Chap. iV.. that the inlet, that is to say the upper opening of the cavity, exhibits four forms, which are met with in aU races, hut most frequently the oval form in the European, the square in the Mon- golian, the round in the American, and the wedge-like in the negro. In 1826 Vrolik came to the conclusion that the pelvis of the male negro — from its strength and thickness: — from the want of trans- parency of its iliac f ossk — from the higher projection of its superior extremity, and from the spinous processes of the iliac bones being less projecting and less separated from the cotyloid cavities, approxi- mates to that of animals, while the pelvis of the negress maintains a certain slenderness. In 1864 Joulin asserted that the transverse diameter of the inlet is always greater antero-posteriorly in the female, and that as to configuration, there are only two human groups — the European and the Mongolian negro. In the negress, he says, the iUac bones are more vertical, the transparency of the fossae, the capacity and depth of the cavity less, the pubic arch, as well as its angle, greater. But M. Joulin had only studied the female pelvis, and M. Pruner-Bey, the year subsequently, set to work to prove that ethnic differences ought rather to be looked for in the male pelvis.* The most general of aU the characters of the pelvis is the relation of its breadth to its length, which has been already described, page 67. In the subjoined table, where the sexes are given separately, the length being equal to 100, the breadth would be : * On the pelvis, see " Considerations sur la Diversity des Bassins des differentes Races Hnmaines," by Yrolik, Amsterdam, 1826 ; " La Doctrine des Formes Primitives du Crine et du Bassin Hmnains," by Weber, 1830; "Des Races de rOceanie Frangaise;" "Du Bassin Neo-Caledonien," by A.

[Chap. iv. the laboratory of M. Broea is so arranged as to furnisli tlie amplest materials for study, and bids fair one day to supply tbe deficiency whicli bas been so long experienced. One fact bas been already ascertained — namely, tbat tbe muscular system is tbe seat of differences : some as to tbe nature of the characters wbioh "we have termed unimportant ; others produced by arrangements which are found normally in various classes of the mammalia. The variations exhibited by the cutaneous muscle, the muscles of the face or of the ears, the adductors of the arm, the rectus abdominis muscle, the muscles of the hand and foot, the glutaai, and the triceps of the calf of the leg are in this category. Some are even repeated so frequently in certaiu individuals of the same race as to lead us to ask if they are not the normal condition in that race, and one of its characteristic features. The skeleton of itself recog- nises the existence of peculiarities of the muscular system, and exhibits them in default of postmortem examination. Thus the development of the temporal fossa, in extent and depth, shows the degree of development of the temporal muscle which was inserted there ; the femur a colonne and the channelled fibula of our ancestors of the Eyzies testify as to the strength and size of their posterior femoral muscles, and of the external muscles of the leg. AH the internal parts of the body are subject to variety in different races : the peritoneum, the ileo-csecal appendix, the liver, the larynx ; and if the small number of cases observed did not lead us to fear pronouncing as an individual variation one of an ethnic character, we might mention many examples of them. ISo doubt special peculiarities in the internal generative organs wUl be dis- covered. Mr. Bakewell at one time thought he had discovered differences in the blood globules : they were attributable to accli- mation. Nevertheless we hope he will continue to prosecute his inquiries in this direction.* * See " On the Various Forms of the Glottis," by Gibb, in " Anthrop.

Soemmering, and after him Jacquart, demonstrated that the nerves of the negro, particularly those of the base of the hrain, are larger than those of the European. It has been ascer- tained that his cerebral substance is not so white. "With regard to the external structure of the brain and its convolutions, no funda- mental difference between them has been as yet discovered ; which was to be expected, inasmuch as there is none between Man and the anthropoid. IsTevertheless there are gradations as regards the richness of the secondary convolutions. The convolutions are larger and less complex in the inferior races. The superior frontal was not unfolded in the Hottentot Venus ; the plis de passage from the parietal to the occipital lobe are exceptionally less superficial on one side, so that the perpendicular fissure is more visible, and the occipital lobe better marked ; there is in fact more or less want of symmetry between the two sides. But these are individual variations, and not characters of race. The weight of the brain, one would suppose, ought to exhibit differences of a more important character. Nothing of the kind. Individual variations wholly prevail, and necessitate, more than in any other character, our carrying on our investigations iipon an extended basis. 'Sow, if weighing the brain immediately after death had been practised on a sufficiently large scale either in Europe or America, it could hardly have been so in countries inhabited by the inferior races. The process of weighing requires the most minute care, and should, properly, be conducted when the brain is in a fresh state, and not after having been kept in spirit. Thus science has but few materials to work with. These variations depend on age, sex, stature, the disease which was the cause of death, the individual's amount of intelligence, &c. We have referred to this at page 120 ; we shall confine ourselves therefore to making an approximate zinski's " Memoirea," already quoted ; " De la Valenr dea Anomaliea Mnsculaires au Point de Vue d'Anthropologie Zoologique," \>j Samnel Pozzi, in " Comptes Eendus de 1' Assoc, pour VAvano. des Soienoes," vol. iii., 1874; &C. 310 WEIGHT OF THE BRAIN.

The difference between them may be as much as 130 grammes, or as great as between the means of a superior and an inferior race. But an entire security is afforded to the comparison of the brain in different races by the individual variations, which are so capricious, and are dependent on so many external circum- stances of original or acquired intelligence, or more stUl on cerebral activity, whatever its physiological manifestations may be. The density of the cerebral substance increases probably, as well as the total volume and richness of the convolutions, by intellectual activity. The brain of an Australian, superior relatively to his fellows around him, will be heavier and have more convolutions than that of a Parisian of' mere mediocre intelligence. The deviation of 20 per cent, in the weight of the brain in the white race is the difference between the average weight of this race and that of the brains of Cuvier and Dupuytren. Supposing that these two cases are anomalies, and reducing the deviation one half, it would stOl be 130 grammes. Here, therefore, more than in any other anthropological character, we must make our calculations upon large masses, in which individualities are lost.

V Eugenesio . . . ) In heterogenesis there may he intercourse without impregnation. Abortive homogenesis is merely a matter of speculation; impreg- nation takes place, hut the foetus does not arrive at its fuU term. In agenesia homogenesis, or agenesis, there are offspring, but these are absolutely sterile iwisr se, or with individuals of one or the other mother-race. In dysgenesia homogenesis, or dysgenesis, these mixed breeds are stiU sterile inter se, but they are fertUe with indi- viduals of one or other mother-race — their offspring, called hybrids of the second blood, being nevertheless sterile, so that it cannot again form a new race. In paragenesic homogenesis, or paragenesis, or collateral hybridism, the direct hybrids, or those of the Jirsi blood, are stiU sterile be- tween themselves, or as far as the second or third generation ; but those of the second blood are indefinitely fertile, so that a race may take its origin by collaterals. In eugenesic homogenesis, or eugenesis, or direct hybridism, the two orders of hybrids are now indefinitely fertile, so that the new race makes its way directly and without hindrance. Heterogenesis is never other than individual in Man, nor con- sequently is agenesis. There was a disposition for some years to believe in absolute dysgenesis between certain races. This must * Memoire, " Sur I'Hybridite," by M. Brooa, " Jonrnal de Physiologie," vol. i., 1838. 2 B 370 CROSSING. [Chap. tii. now he given up. The whole dispute concentres upon the two latter kinds : Are there unions which could not give origin to a new race except by collaterals, that is to say, by a reversion towards the one or the other mother-race 1 There are numerous species of human mongrels. There are (1) Those of the first blood, including their direct ofi'spring, and all those which are derived from them by alliances with them ; (2) Those of the second blood (first degree of reversion), including all the offspring of the cross of the first blood with one of the two mother-races ; (3) Mongrels of the third blood (second degree of reversion), resulting from the cross of the second blood with one of the mother-races, and so on. At the fifth or sixth reversion aU trace of hybridism has generally disappeared, the features of the mother-race have reverted to the origiaal type. That there is but one species of mongrel of the first blood, but two species of the second, of the third, of the fourth, each resembling more one of the two original races, is certain ; and also that there are complex and nameless cross-breeds resulting from the cross of mongrels of different orders. If we express by W, or white, and B, or black, the two races, and by a fraction the amount of each according to its degree, we shall have the f oUowiag series of reversion towards W : Mongrels of first blood „ second blood „ third blood „ f ourtli blood „ fifth blood = W| -1- Bi. = Wfl + B^. Homogenesis is absolute or eugenesic, and still more paragenesic, between contiguous races. The peoples of Europe are a proof of this. All, in various degrees, are the resultant of a series of cross- iags, one of the most striking products of which is the co-existence, in one and the same individual, of light or dark blue eyes with jet-black hair and beard. A friend of our own who traces back among his ancestors elements on the one side reaching to the Chap, vii.] CROSSING.^ 371 Western Pyrenees and on tlie other to Lorraine, is an example of this. M. Broca found, when investigating the subject of stature, that nineteen-twentieths of the whole population of France presented, in various degrees, the characters of mixed races. The Bretons are one-fourth Kymris and three-fourths Celts, without including another element which is seen among them, and which dates hack to a later period than the Celts. Up to the time of the French Eevolution victors and vanquished lived apart; the former were the aristocracy, the latter the people. But since they have been brought more into immediate contact the population Jias largely increased, proving how valuable that union has been. The table which we have constructed with materials furnished by Dr. Beddoe, shows that everywhere throughout Europe, and even among the Jews, two elements must be taken into account, the fair and the dark, which are promiscuously intermingled. The prosperity of the New American race is another example of eugenesis. Immigration into the United States, which has taken so considerable a flight during the last thirty years, has already been enormous. Every variety of cross has been going on between English, Irish, Germans, Italians, French, &c., with the greatest possible success. We may also mention numberless Spaniards from the Peninsula among whom are found the features of the Saracen invaders of the ninth century ; then that poptdation on the Barbary coast, called Moors, and which is a medley of races of every description, the Arab and Berber blood predominating. On tracing back the yellow races we also discover a perfect eugenesis. It would be difficult in the part of Asia which relates to them to mention a single race, or a single people, where crossing has not taken place. De Mas speaks in the highest terms of mixed breeds ■of Chinese and Mongolians, and MM. Mondiferes and Morice of those of Chinese and Aanamites under the name of Minuongs. Dr. Bow- ring describes a race in the Philippine Islands, intermediate between the Malays and Chinese, as the principal agent of civilisation in these latitudes. Their mongrels, which are said to be thriving but little in the Eastern Malacca Islands (Waitz) and those of Chinese and Cam- 2 B 2 372 CROSSING. [Chap. vii. bogians but little fertile (Gutzlaff), are local exceptions, arising from the difficulties attending acclimatisation in these unhealthy countries. One of the first effects of the inability to become acclimatised is to diminish fecundity. The Mamelukes of Egypt during 560 years have had no children when married to women of then- own race from Georgia, and have never established a branch in the Valley of the Nile. Such are some of the singular pheno- mena which everywhere present themselves when we have to deal with the question of reproduction. The failure of power to become acclimatised seems to attack the germ in its very earliest develop- ment. It is undeniable that in Africa the negro races do not cross to any great extent. The Kaffirs have carried their tall stature to a great number of points ; the Bosjesmans have here and tliere loft traces of their steatopyga and their small stature. On the present frontiers of the two races a number of cross-breeds are to be met with. Eugenesis still continues between races already somewhat separated from one another. The half-breeds between Indians and Europeans are very numerous both in North and South America. We ourselves have seen, in the United States, numerous families, the issue of the Indian and the Yankee, whose offspring were very fertile. In the official report, in 1870, upon the Aborigines, it is stated that there exists in Kansas an entire nation of half-breed Osngos. In Mexico the Spanish mixed breeds constitute two-thirds or three-fourths of the whole population. In Brazil, La Plata, and Chili, the Portuguese mongrels are also in the majority. In Lima there are twenty-three different names to designate the varii'ties of mixed breeds of Spaniards, Peruvians, and Negroes. The children of the half-breed between the Chinese and the Spaniard are called tornas atras, according to Dr. Bowring. The facility with which the Chinese interbreed with every sort of race is well known. In the Antilles and in California, they are to be found everywhere, and they interbreed with the Indians and whites, thus producing many varieties of mixed progeny {A. Maiirij). The reason why these are not greater is that the Chinese marries and returns to his own country as soon as he has amassed a com- Chap, vii.] CROSSING. 373 petency. The inferiority of the mixed breeds between the Chinese and the Portuguese, so conspicuous at Macao (Castano), ought still to be attributed to acclimation, in the same way as the Lippladens, or half-breeds between the Malays and the Dutch, which have never suoceenlod in establishing themselves in Java, and whose progeny were sterile to the third generation (Ivan). In the It'i'onuh colony of Ind(i-("!hina, M. Morice speaks of half-breeds of Europeans and Annamites as resisting exposure to the sun better than their European relations. Fitzroy describes the children and infants of the English and Malay, or Polynesians, as of a bright roil-brown. The half-breeds of English and New Zealanders con- stitute a healthy and very muscular race, according to Waitz. Prichard speaks of marriages between the progeny of Europeans and aboriginal Samoans and Tongas as being as prolific as any other. The success of the Polynesian mixed breeds is no longer a matter of doubt. In 1789, nine English sailors, six male Tahitians, and 15 Tahitian women settled in Pitcairn Island, in the Pacific. In 1793 they were reduced to four white men and 10 Tahitian women. In 184G the population of the island increased to 66, and in 1856 to 189. Moreover, at the termination of Cook's voyages, the I\ilynesian races were still unmingled with any infusion of white blood. Now, their mixed breeds are so numerous that it would be difficult to find among them any individuals of pure race (Do Quatrefages). In Africa, the Soudan is the great centre of mixed breeds between two raees equally removed from one another. Here, in the tenth century, there appeared a red race with glossy hair, commonly known as that of the Foulbas (Barth), which engrafted itself as a dominating race upon a previous negro stock with wooUy hair, and giving origin t jChap. Till.] INFLUENCE OP MILIEUX. 389 «anie there at the period of the destruction of Jerusalem, and ■whose history can be traced back at least six centuries. Ifow ihese have remained white, or rather brown, from the climate, and 3,3 compared with ourselves, but white as compared with the sur- rounding nations. Their children are born white, and their wives -when not exposed to the sun remain white. Notwithstanding all we have said, external circumstances have An undeniable influence certainly. Vegetables become white when excluded from the light, and not only on the surface but throughout their entire substance, and it even affects their flavour, and extends to other properties of the sap. The animals of the polar regions become white on the approach of winter. The small and puny x)xen of the Sologne when transported to the valleys of the Loire, in one or two generations assume an entirely altered appearance as regards their size and quality. Peasants and sailors become tawny on exposure to the open air and in hot countries, on the uncovered parts of the body. But in the last-mentioned case the influence is confined to the individual, it is not hereditary ; it is also different in different races. We have said that dark and fair Europeans do not tan equally when exposed to the air ; the former readily become black, the latter become sunburnt, and of a, brick-red hue, or assume a yellowish tint, which Monrad considers as the first .evidence on the coast of Guinea of having become acclimatised. This yellowish colour passes into that of copper, and becomes darker in each succeeding generation. The Chinese also become Tjlack on exposure to the sun during the summer, and light in winter. There is a vast distinction between this and the individual's transmission of an acquired character to his posterity. The individual becomes black as he becomes fat. If excluded from exposure to the sun, and his food is scanty, he becomes pale and thin. In the Sandwich Islands an opposite phenomenon takes place (Choris). The children when first born are black, the people of distinction dark brown, and the labouring people of a lighter tint, or orange colour. But this is a difi'erent matter; one ought perhaps to look upon the two classes as two distinct races. 390 INFLUENCE OF MILIEUX. [Chap. viii. Nevertheless we admit that modifications of physical characters- might he produced, if not under our very eyes, at least in the course of time, and might be added to from age to age. We must, admit that these things might be explaiued physiologically accordiag to this hypothesis. Stature, for example, is the result of two influences. (1) Of the race, or rather of the predominance of action of such race whether a paternal or maternal ; and (2) Of a concurrence of hygienic circumstances. According as the nutrition of the skeleton goes on properly or not, its ossification is or is not regular — the epiphyses- are united to the diaphyses soon or late — so will the individual be either tall or short. Let the accident be repeated, let the phenomenon go on in the- same way during many generations, it will become a habit (lq mediciae we recognise pathological as well as physiological habits, and their tenacity and hereditary character are truly remarkable), and soon a regularly transmissible character. "We cannot there- fore be surprised to see the persistence with which travellers, those ia Australia for example, assert that individuals of low stature in that country, are badly fed, poorly clad, and miserable, while tall statures are characteristic of the natives of the interior, who are strong and healthy, having every resource within their reach. Individual varieties unquestionably depend partly on external circumstances, and partly on the state of the health. M. Broca himself allows this as regards certain differences between the sexes.. Some statistics of Quetelet relative to healthy and diseased children prove it. The increase of the pigmentary matter might also be easily explained in this way. The cutaneous system, excited by contact with the air, heat, and light performs its functions more readily,, its glandular apparatus secretes more, and the black matter is de- posited in greater abundance in the cellules beneath the epidermis. Trom this cause, and probably by reflex action upon the supra-renal capsules or the Hver, the hypersecretion would be diffused through the entire organism, and the colouring matter derived from the blood, from the biliary matter, or from elsewhere, would increase. Chap, viii.] INFLUENCE OF MILIEUX. 391 Peculiarities proper to each, race ■vvould "be that one would become decidedly Hack, another yellowish or olive, a third reddish. An objection of this sort might arise : Why the parts exposed to the air are not the only ones black? The opposite phenomenon, a want of excitation, would, on the contrary, produce pallor, that is to say a sort of anaemia, as in miners. The white An.tisians of Peru, says D'Orbigny, live at the foot of perpendicular rocks, under enormous trees, the branches of which form a vast arbour impenetrable to the rays of the sun, where the atmosphere is humid, and the vegetation luxuriant. Their five tribes live there enveloped in darkness, and are of lighter complexion than the Moxos of the adjoining open plains, and the Aymaras on the elevated plateaux. As regards the increase of the volume of the skull and all the craniometrical characters which result from it, the explanation would be no less easy. The more the brain works the more does it continue to increase beyond its ordinary term of growth, and the sutures are closed later. The small size at the present day of the skull of women relatively to that of men, as compared with that which it was at the prehistoric period represented by the two beautiful series from the cavern of L'Homme Mort and the Baye caves in the department of La Marne, would arise from an opposite cause. The variations of the forms and proportions of the skeleton might be all explained in the same way, by virtue of the physiological law, that the function makes the organ. The more work a limb, or an organ, or a muscle does, the more it increases in volume ; changes at the same time taking place in the parts with which it is con- nected. The femur a cdlonne, the platycnemic tibia, the large chest of individuals compelled to take deep inspirations, the corpulence of persons who confine themselves principally to a vegetable diet, and whose meals are irregular, and sometimes very large in quantity, are accounted for in this way. "So explanation can be given as to the varieties of the hair in its fundamental types. For example, the straight and round, the woolly and fiat hair, as seen under the microscope. In this lies the most serious objection to the theory of the derivation of characters 'from one another. In tbe present state of science we have no 392 ACCLIMATION. [Chap. vm. ?xplaiLation to give on the subject. Individuals experience the iniiuence of external conditions under our own per.sonal observation, but they do not visibly transmit the changes so made — there is no Buthentic instance of it. The distribution of characters according to altitudes and latitudes has exclusively to do with the fortuitous migration of peoples. In the present state of science, and as far as our limited investigations extend, the law of permanence of types remains intact. Moreover, physiology enables us to understand the mechanism by virtue of which new characters might take their origin. Under what exceptional conditions, at present unknown to us, may not hereditary influence, that great conservative force, depart from its extreme strictness ? This is the question. It is quite clear that the variations of climate and conditions of life are very slight now in comparison with what they necessarily were formerly. The fact is that Man has not always known how to guard against the preponderating influence of external agencies, nor has he always been able to leave the country under every change of circumstances. No new race, having characters other than those of the mixed races produced from crossing, has been created within our knowledge; and moreover, everything compels us to believe that there was a greater tendency to change at a remote period in the past than there is at present, and this belief has found a support in the law of hereditary influence. It is one of two things : either races have been created originally in infinite number, and have since become diminished by natural extinction or by crossing, or they have been multiplied under the influence of climate and external circumstances.* Acclimation. There is but a step from the influence of climate and external conditions to acclimation. Man, unlilce the anthropoids, is found in all climates, and conforms himself to every condition of Hfe ; but * See the articles " Altitude," by Leroy de Mericourt ; " M&ologie," by Berfcillon; "Climat," by Fonssagrives ; "Atmosphere," by Gavarret, &c., in " Eocyol. des Sciences Medioales." Chap, viii.] ACCLIMATION. 393 Jie owes it to his intelligence, and pays the penalty. Let us examine tlie question more closely. The words acclimation and acclimatisation are not synonymous. The former is understood of the spontaneous and natural accommo- dation to new climatic conditions, the latter of the intervention of Man in tliis accommodation. The one is the fact, the other the •knowledge of the conditions and phenomena of accommodation; the one is a physiological property of Man, and concerns anthro- pology, the other is in the domaia of hygiene, of medicine, and of the schools. M. BertUlon has treated of them, from every point of view, with his usual critical acumen, and it wiU suffice for us to analyse his article, " Acclimatement," in the " Encyolop^die des Sciences Medicales." M. BertUlon commences with a comparison of the statistics of hirths and deaths. He finds differences hetween one race and another, either in their general faculty of acclimation or in their capabUity of living in some latitudes in preference to others. He discovers differences even between European races. Thus the English become habituated to the climate of the United States, the island of St. Helena, and the Cape of Good Hope, but they fail to do so in the Antilles and in India. In the same way the Germanic race thrives in the United States, but dies out in the tropics, and even in Algeria. The Dutch likewise. Under the name of Boers they continue to live under the most favourable conditions in the colony of the Cape, the climate of which is very similar to that of our own country, whUe they perish under the scorching climate of the Malay peninsula. The French do well in Canada, in jS'ova Scotia, in the United States, in the Mauritius and the Friendly Islands, but as they approach the tropics their faculty of adaptation decreases. In the Antilles they succeed in making a first branch, but they do not increase, and requii'e to receive fresh blood by crossing with foreigners up to the third or fourth generation. In Algeria the French belonging to the northern departments do not thrive, whUe those of the south make progress. In Madagascar, and especially in Senegal, no European race can hold out long. In IsTew Caledonia the mortality among French emigrants is less than in France. The Spaniards, in whose blood there is much of the 394 ACCLIMATION. [Chap. Tin. Berber, adapt themselves wonderfully to tlie climate of the southern part of the United States, of Mexico, the Antilles, and South America. These, with the Maltese and Jews, are the most favoured of Algerian colonists. The Portuguese share with them the same privileges. The Tschinghani, Gipsies, or Bohemians, are, of aU peoples, those whom we meet with most universally. In the waste lands of Brazil, on the summit of the Himalayas, in Moscow, Madrid, London, Stamhoul, at 30 to 35 degrees centigrade above zero, in the torrid zones of India and Africa, they are to be found everywhere. The IsraeHtes also possess a remarkable aptitude for becoming acclimatised ; but they do not advance so much towards the north, they proceed step by step, cautiously feeling their way, and follow the course of civilisation. The Arabs readily become accHmatised, but they remain in hot isothermal zones, and venture but little into the temperate zones. M. Bertillon does not speak of the Chinese, but everyone knows that they are much esteemed as labourers in Malacca, Australia, California, and the Antilles. Since the abohtion of slavery in America, they are gradually taking the place of the negro, owing to their soon becoming accustomed to the climate; but we have not seen them emigrate into cold countries. Austraha, although having the most opposite cHmates, is very suitable to Europeans of every nationality, while the Malay Archi- pelago, more especially the northern part, is very fatal to them/ Cochin-China the same. In Java and Sumatra the Dutch do not become acclimatised, and this no doubt is the cause of the sterility of certaia of their mixed breeds with the aborigines for a definite number of generations. India is also fatal to Europeans, but the low plains situated on the sea-shore, and the banks of the great rivers, must be distinguished from the elevated plateaux of Central India. The English have established sanitaria in the mountains, where they go to recruit their health. Egypt is no less remarkable for its insalubrity. Its present population is the same as it was in former days. It has never been maintained without being incessantly renewed by immigration. It is very' Chap, tiii.] ACCLIMATION. 395 fatal even to the negro. The Mamelukes have had sway there for 660 years, and not one has been able to keep up a persistent race. The rate of mortaUty among the negroes of Africa, even in their own country, is considerable. The birth rate however is very high; but for this they would become extinct. This mortahty seems to be consequent on their indolence, and on their using no exertion for their well-being. We must not therefore be astonished at their success in America, where, particularly in the Antilles, and in the United States previously to the war, they were taken care of like valuable merchandise. In 1808, the period when the importation to that country ceased, they were 400,000, in 1860 their number increased to 4,000,000. Since the war they have been compelled to look after themselves, and have returned to their natural indolence ; thus their number is diminishing. So much for emigration into hot countries. In cold regions, Eiwopeans do not readily become acclimatised, and negroes especially die rapidly. The fair population of Iceland is visibly decreasiag, which is to be attributed to the island becoming progressively colder. The Esquimaux, who on their first arrival in Greenland found a climate which was more sup- portable than now, decreased for the same reason. At St. Peters- burg the deaths exceed the births, and if the Slavs are masters of the northern part of the continent, they owe it to their crossing with the Fins, and perhaps, more to the west, with the Samoiedes. Thus it appears that extremes of climate are not suitable to any race, and that if Man transports himself from one part of the globe to another, and settles down there, it is frequently at his peril, notwithstanding the resources with which his inteUigence furnishes him. The fair races are especially adapted to temperate and cool regions, and the south is looked upon as almost forbidden ground. The brown races, on the contrary, have a . remarkable power of becoming acclimatised. In the north they are represented by the Laplanders. They stretch away as far as the equator, thfe most characteristic of them especially. But when considering the question of removing from one climate to another, we must (iistiucuish between shght and important changes, between those 396 ACCLIMATION. [Chap. viii. which are sudden and those which are progressive. M. BertUlon divides the accidental circumstances due to sudden acclimation in a new isothermal region, and are produced upon the individual and Ms progeny, into four groups or phases. (1) Sudden diseases ; (2) Chronic consecutive anaemias, which place the individual in an unfavourable condition to resist accidental diseases, or make him quickly look old ; (3) Diseases of early infancy in offspring horn in the country ; (4) Physical and intellectual degeneration, and the infertility of the second and third generations. (See page 372.) Very different are the circumstances connected with acclimation on a small scale. A family incapahle of heing suddenly transported from Paris to Senegal is well able to bear removal to Pau. In succeeding generations it will be able to go to Cadiz, many genera- tions afterwards to Morocco, and so on. It is thus that the slow immigrations from Central Asia have been accomplished — not the invasions of the barbarous tribes which rushed down upon Europe at the commencement of our era. Some of these migrations bearing off to the north-west would have reached comparatively cold, countries, and others going south would find India, where at the present time some fair people are to be met with in a country where the English could not settle. The Esquimaux, before becoming acclimatised in their country of eternal snow, lived in Asia, at about the 40th degree of north latitude. All parts of a country are not equally unfavourable for acclimation. Without speaking of a swamp here or a desert there, which increases the mortahty among new-comers, there is the altitude to be taken into consideration. A family wiU not be able to become acclimatised at the level of the sea, and will thrive by ascending the course of a river or the sides of a mountain. High table-lands are in much request in all hot countries. The contradictory opinions of Joui-danet and Coindet relative to the residence of Europeans in elevated parts of Mexico, leave the question undecided. But in a French territory the experiment has been made. Whilst Bortillon and Eicoux come to the conclusion that the Germanic race, in a general way, does not become acclimatised in Algeria, we find in the entire province of Constantine, and on the whole line of the Chap, tiii.] ACOLIMATION. 397 Atlas, from the Aurfes mountains to Morocco, a large number of fair people, who have existed there for four or five thousand years. A circumstance favourable to permanent acclimation is the crossing, however little, with the native race, or with other races which have settled in the country at the same period with it, but with a greater power of acclimation. A small quantity of negro blood lessens the tendency to contract yellow fever. So at the Cape of Good Hope, in the United States, in Australia, and also in Algeria, the emigrant races must not be designated by their particular name, but must be looked upon as new mixed races, having their ovm special characters. Under these conditions the influence of climate and external circumstances appears even more marked, the same as in chemistry certain re-agents act more readily when bodies are brought into contact in the nascent state. After the greatest mortality, a few of the survivors are suificient to serva as a starting-point for a new population. In a word, Man's restricted faculty of acclimation may favour, within certain limits, the diffusion and mixture of races on the face of the globe, and even the formation of new races ; but it is also an obstacle to their diffusion and transformation. It tends to allot them a place at the period which is the most suitable to them. This is why we see the negro races generally predominating in some zones, the brown or yellow in others, and the fair races in others. Having the minimum mortality in these zones, the race is kept up. The fair races, for example, far from being so on account of climate, as Prichard would have it, would only conform themselves to it in the same way as the prehistoric animals which went northwards or southwards in the course of ages, according to the changes of temperature and vegetation. If we did not know that the climatic conditions of all parts of the globe have radically changed over and over again, we should deduce from this that the negro races took their rise on the continents of the inter-tropical zone, while the fair races originated in the cold or temperate regions of the north. It is thus that the faculty of accommodation to climate or acclima- tion, which varies according to race, furnishes an argument for the polygenistic doctrine. The two questions of crossing and of 398 WEIGHT OF THE BODY. [Chap. tiii. inheritance are connected with, the functions, so mysterious, of reproduction ; those of external conditions and acclimation, to the more general function of nutrition.

Its causes are various, such as hygiene, food, character of occupation, temperament, and race. The probable connection between these last two makes it the more difficult to consider the question of race by itself. The cases of exceptional obesity, due to high feeding or to indolence, are observed in aU races from the Englishman to the Hottentot, and ought to be at once set aside, as well as those cases of extreme emaciation, conse- quent on habitually insufficient food, or continued exposure to the sun. The Arab, shrivelled up in the desert, becomes fat in the towns, especially his half-breeds. The Mongols, the Chinese, and the Polynesians readily become obese.

Muscular strengtli is a more important subject, altliougli we must consider it ui its connection -with the individual's state of health, food, age, and sex, as ■well as with the power acquired hy the continued use of the muscles. The dynamometer, hy the aid of which the experiments which we are ahout to mention were carried on, was invented hy Eegnier, at the close of the last century, at the suggestion of Buffon. Chaussier was the first to make use of it, then the travellers P&on, Freycinet, Quoy, and Gaimard, and lastly, Forhes, Quetelet, and the anthropologists of the Novarra and of the war of American secession, who modified it. It gives, at will, the force of pressure of the hands, and the force of vertical traction from helow upwards, the two hands acting together in both cases ; that is to say the manual strength and the strength of the back or loins, of authors.

The ahove averages clearly show that the Austra- lians are very defective in manual strength, but that the Chinese are stiU more so. Those with the greatest amount of strength in the baclc, on the other hand, are the Iroquois Indians, and after them the natives of the Sandwich Archipelago. Negroes are undoubtedly stronger in the back than whites, but mulattoes are stronger than either. The muscular inferiority of the white seamen of Eansonnet and Gould clearly proves that the physio- Chap. Till.] CIECULATION OF THE BLOOD. 401 logical condition surpasses in all cases the anthropological condition. In his statistics Mr. Gould has separated the delicate from those in perfect health, the difference between them being considerable. Thus, in white soldiers of delicate constitution the strength of the l)aok was 127 kilogrammes, and in those in health 155 kilo- grammes. Another and more portable dynamometer is recommended in the " Instructions de la Soci^t^ d'Anthropologie," that of Mathieu, figured in. the preceding page. It measures the force of pressure •with one hand, and the force of vertical traction, as with the instrument of Eegnier. In twenty-four Frenchmen, from 20 to 60 years of age, the mean manual strength was 51 -6 kUogrammes with the right arm. But it would be better to ascertain correctly the ; force of horizontal traction, as, according to M. Broca, it is this T^hich gives more reliable results as between one race and another.* To the functions of nutrition indirectly belong those of the circulation, respiration, and digestion. AU have reference to organic life, and cannot materially differ between one race and another. The Circulation of the Blood. The circulation of the blood may be summed up in one single phenomenon — the beating of the heart, as indicated by the pulse at the radial artery. But more than any other phenomenon it is subject to transient or permanent influences foreign to Anthropo- logical notions. The pulse varies with age, sex, individual peculiarity, stature, and also with the size of the body, before and during digestion, in the morning and at night, after exercise of any kind, and under the influence of emotion, even that caused by the examination of the individual. We cannot therefore deduce much * " Description et Usage du Dynamomfetre," by Eegnier, in " Journal de r;fioole Polyteohnique," vol. ii., Prairialyear 6; " Voyage autour dn Monde de I'TJranie et de La PfiA/sicierme, de 1817 ^ 1820," two vols., by L. de Freycinet; J.

The respiration presents eonsiderahle diversities in different individuals ; some of these are of a radical character, others are consecutive to the action of milieux. The movements of the chest concerned in inspiration are three in number — namely, an upper costal, a lower costal, and an abdominal or diaphragmatic. "We have yet to know whether either of them may or may not be peculiar to certain races. The rhythm of the respiration may also- vary, although it usually bears a definite relation to the pulse, there' being one inspiration to four beats of the heart. Quetelet found that in the Belgians in the above list, the inspirations were 18 in- the minute, and Hutchinson that in the English there were 20. According to Coindet the respiration increases the higher one ascends. Supposing, in 250 Europeans, the number of inspirations were 19'3, in the same number of Mexicans, at an altitude of 2277 mfetres, the number would be 20'3 — the correctness of which state- ment M. Jourdanet questions. The difference, however, is scarcely appreciable, and the number of individuals too few to enable us to form a definite opinion on the matter. The capacity of the thoracic cavity is a subject which has received a considerable amount of attention. It is ascertained with the sphometer. The individual makes a full expiration and then a full iaspiration, three times in Chap, viii.] OIROUMFEBENOB OF THE CHEST. 403 succession, wlien tke mean is taken. Of all tte physiological causes which tend to make it vary, like every other animal func- tion, the most important is the stature. In 1080 Englishmen Mr. Hutchinson found, with a stature of 1 '52 mfetre, a capacity of 2-842 cubic mfetres, and with an addition of one inch in height, namely, 2-54 centimetres, an increase of 131 cubic centimetres, so that with a stature of 1-82 mfetre, the capacity is 4-260. M. Sehreevogt finds it less in the German race — namely, 52 cubic centimetres for every centimtoe of height. The following table, having reference to healthy adult men, shows that there are material differences between races : Cubic mfetrea 8895 White soldiers (Gould) .. 3-054 1631 Negroes „ .. 2-700 671 Mulattoes .. 2-629 504 Indiana „ .. 3-022 1080 Englishmen (Hutchinson) .. 3-602 From this it appears that the chest capacity is less in negroes than in whites, and especially in the EnglisL Ifow the stature of the former averages 1 -70 metre, and that of the latter about 1 -71 in the corresponding statistics, so that negroes maintain their inferiority. With regard to mulattoes, it is with them as with their brain — (see page 312) — they seem- to appropriate the worst character pertaining to the two races of which they are the issue. Their chest capacity is even less than in pure negroes. The Gircumference of the Chest. The circumference of the chest is connected with the study of the respiratory functions, as well as with that of the proportions of the body ; it has even to do with that of the reproductive functions in the female : hence it presents differences according to race. We shall only speak, however, of the measurement in the adult man. The works which have been -written on the subject are numerous, 2 D 2 404 CIKCUMFERENCE OF THE CHEST.

When measuring a man's chest the tape is passed round under the armpits, or, what is better, over the nipples. The individual should stand upright, should be calm, his respiration being carried on quietly, the mouth open, the arms above the head, and the hands joined, imless we want to take the mean circumference during inspiration and expiration. As the capacity of the chest increases with the stature it is necessary to take account of this. In the following table the first column shows the absolute circumference, and the second the same circumference relatively to the stature = 100 : 5738 Scotchmen (Quetelet) ... 508 Indians (Gould) 1080 Englishmen (Hutchinson) 462 Germans (Gould) 4930 Russians (Seeland) 400 Frenchmen (Bernard) ... 1792 Negroes (Gould) 719 Mulattoes „ 151 New Zealanders (A.

Tlie digestion also varies, if not according to race, at least so far as to produce certain effects "wliich. may become permanent. It is influenced by certain habits. Thus, according to the regularity or irregularity of the meals, a redimdance or insufficiency of food, a herbivorous or a carnivorous regimen, the stomach •will become distended and deformed, as is the characteristic of many inferior tribes, or be retracted. The lumbo-sacral curvature also wiU be more or less hoUowed. The teeth will become worn, horizontally, almost down to the gums, as in the Patagonians, or obliquely, as in our prehistoric races. In truth, in anthropology we must study aU the functions of the body exactly as we study the corresponding organs; and these functions may exhibit differential characters between races which we least expected, or throw some light on the problem now under consideration with reference to the influence of external conditions and habit. Next to respiration and digestion, therefore, come the functions of the larynx, of the senses, &c. The Voice. The voice varies in its quality and tone in different races, and may even be characteristic of certain human groups, according to the statement of travellers. The tenor or bass voice is frequently associated with a certain physical type. This subject belongs more particularly to linguists, whose attention is specially directed to differences of pronunciation. Much has yet to be done in this direction. Vision. Vision may be studied with respect to its extent. According to Mr. Gould, the white, the negro, and the Indian see at the 406 CEREBRAL FUNCTIONS.

Cerebral Functions. The cerebral functions are to be examined in the same way as all the others. Intellectual phenomena are the expression of the activity of. the brain, while their external manifestations are its product. Both the one and the other are consequently included in the category of physiological characters which we are now studying. They present the greatest anomalies, because this is precisely the general characteristic of the human family, but they also exhibit marked differences, which doubtless were more, considerable at first when races were in a condition of isolation. There are two cha- racters common to the whole human race : the faculty of imitation "Chap, viii.] CEBBBEAL FUNCTIONS. 407 and tlie faculty of improvement. The ape repeats that -wMcli lie sees done, and goes no farther. Man profits by what he sees, and is more or less capable of heiag educated. Hence the difficulty, when analysing intellectual traits, to distinguish that which apper- tains to the race and to the individual from that which is the result of education and of training. ISTot only a victorio\is tribe, but a single individual starting up as if by chance, may so transform the customs and modify the characters of a people as, after a brief period, to render them unrecognisable. The ancient Peruvians owe most of the intellectual traits which distiaguish them from neigh- bouring races to Manco-Capac, the first of the Incas. Who knows whether the AustraKans might not have become elevated in the social scale, if they had met TPith a man who knew how to deal with them 1 This proneness of Man to appropriate to himself that which he can make subservient to his wants and desires, and to , l^ransform himself intellectually, is not equally developed in all. In some it is acquired rapidly, in others slowly. "We know that the Andamans and Australians, brought up according to our ideas of ■civilisation, cast off their clothing on the first opportunity, and resume their savage mode of hfe ; notwithstanding this, these same savages quickly learn to read and write, and are very observant. Hence we must distinguish between the rough-and-ready education of an individual, and the lengthened and progressive education of a race. In spite of this tendency to intellectual uniformity in the human family, certain differences persist, each corresponding to certain peculiar anatomical conditions of the brain, which they denote as surely as though demonstrated by the most delicate microscopic examination. Among those properties inherent in the structure of the brain, the faculty of language occupies a prominent place. Linguists lave come to the clearest conclusions on this point. A certain number of languages irreducible from one another have had an independent origin. At that remote period the corresponding primitive races lived distinct in a state of nature. Has chance then presided at the early development of a few articular sounds, which have become the point of departure of so many root- words ? 408 SOCIAL CONDITION OF YAEIOUS EACES. [Chap, viii, or lias the brain become previously modified in order to render this- development possible] "What interests us liere is tliat there are languages profoundly different from one another, which require organs of a special construction to pronounce them, and special powers of intellect to comprehend them. In the same way we ' must view the various methods of appreciating the musical gamut in the several quarters of the globe. That which is harmony to the auditory fibres of the brain in some races, is not so in others. Education here has nothing to do with it ; the thing has been so- from the first, and is, therefore, an anatomical fact. The varieties of arithmetical systems are in the same category. The races termed Aryan are acquainted with all of them, and have considerable aptitude for mathematics. Other races, styled inferior, cannot count above two, or three, or five ; any numbers above these are altogether incomprehensible to them, and in spite of all our efforts we can seldom give them any higher notion of number : this was the case with a Damara mentioned by Lubbock. As regards draw- ing, there are difi'erences in the same way. There is a race, the existence of which can be undoubtedly traced back to the earliest period, only capable of making circles and straight lines, and certain of its representatives cannot even distinguish the difference between a drawing of a head and a tree or a ship. The Chinese, after a social existence probably equal to that of the ancient Egyptians, and, although advanced in many other respects, have not the slightest idea of perspective. Other races, on the contrary, and these the most ancient and the most savage, as our ancestors of the Eeindeer Period, have exhibited almost from the first, a thoroughly artistic taste. The marvellous difference in the systems of writing testifies also to the primitive isolation of races and to their various degrees of aptness and impulse. The perfection which some seem to have attained almost from the first, whilst others have remained in statu quo, is well worthy our consideration. Eaces are still more distinguished from one another by their mode of life and social condition. Erom the earliest dawn of tradition, and even previously, when all our information is derivable only from prehistoric archteology, we see tribes settling- Chap, viii.] CHABACTBE OF THE FRENCH. 409' down peaceably, engaged in fisMng and barter, as well as those of a warlike and turbulent spirit. The former soon become amenable to the softening influence of civilisation, the latter, on the contrary, are proof against it, and prefer a rough and savage life. The former are sceptics, or indifferent to religious forms ; the latter recognise a protecting Providence, and have a settled faith. Some are naturally inclined to a sedentary hfe, while others seem to be always on the move, like the Tschinghani, the Jew, and the Arab. The Tschinghani have no religion, and wander about in the midst of civilised peoples without allowing themselves to be influenced by them in any way. The Jew, now a wanderer, and then a sojourner, from the time of Joshua to that of Titus, has again become a wanderer, as far as the customs of the peoples among whom he dwells will permit. The Arab also retains his old habits, only he does not adapt himself to them. He moves away to India, into Central Africa, in search of fresh moorings, but does not remain long anywhere, like the Anglo- Germanic race. No one doubts the value of intellectual characters. It would be commonplace to say that they continue for ages in the same way as physical characters. The Spaniards of the time of Scipio jEmilianus are still those of to-day. Fighting in ambush, long patient endurance, and hatred of the foreigner are always their distinguishing marks. The predominating character of the French race is still that of the Gauls described by Csesar. In Algiers, the Berbers are distinguished from the Arabs more by their disposition, their temper, and their sociability than by their features of coun- tenance. The contrast between the Anglo-Germanic and the dark southern race is also very striking. The impulses inherent in the cerebral matter are so tenacious, in spite of education and civili- aation, that they still continue after crossing and mixture of races, and are of assistance to us in recognising them. Mr. Brace depicts the character of the French in these terms.* "In character and genius the French show the evidences of the three powerful races which have constituted the nation — traits which sometimes seem * "The Races of the Old World: a Manual of Ethnology." By C. L. Brace. London, 1863. 410 PRIMITIVE CEEBBRAL DIFFERENCES. [Chap. viii. contradictory, and -which, only those familiar with the Prench people can fully understand. In their hrOliant martial character, their love of display and effect, their sudden enthusiasm and as easy discouragement, their readiuess to he governed hy military leaders, their fondness for ornament and art, and their gaiety, fickleness, and amorousness, they are thorough Kelts ; but in the sober devout- ness of a large mass of the people, in their seriousness, in their personal sensitiveness and personal independence, in their spirit of sceptical inquiry and the thoroughness of their scientific research, they are Teutons ; vrhUe their marvellous talent for organisation, and their tendency to centralisation, are Eoman. The French race, with its genius, its science, its grandeur, its faults — which are the scorn of mankind; its misfortunes — which afflict the world; its magnificent past, its uncertain present [the author wrote under the Empire], and mysterious future, is a unity, a new and living force entering into the life of mankind, and henceforth as distinct as any •of the great races of antiquity." The points of view from which one might treat the vast subject of primitive cerebral differences are infinite. Each fundamental race would require to be submitted to minute analysis, and every- thing eliminated from it which is due to a natural state of perfect- ness, to accidental occurrences, to the influence of other races, and to historical circumstances. The power of each faculty, feeling, or instinct would have to be taken into account. Superstitious, tendency, religion, family history, individual peculiarity, degree of sociableness, aptness for civilisation, preference for this or that kind of life. All these wordd have to be. examined. What the varied amount of cerebral activity in the so-called higher races, as com- pared with the torpid condition of those regarded as inferior, &c. It seems, says Sproat, speaking of the Atnas of ]S"orth America (Lubbock), that the intellect of the savage is in a half-sleepy state. If we hold conversation vri.th him for however brief a period, he becomes fatigued, especially when his replies require some effort of thought and memory. The savages of the interior of Borneo {Dallon), as well as some from Western Australia {Scott Nind) live in a state of the most absolute indifference, like animals. Their sole business Chap. Tin.] INTELLECTUAL DETBLOPMENT. 411 is to eat and drink. There are numerous examples of savages, as the Bosjesman described by Lichtenstein, in whom there is nothing either in features of countenance or in their actions indicative of the least glimmer of intellect. A subject, almost a new one, has for some years excited much attention : namely, the history, based on facts, of the steps whereby the most favoured of the human races have arrived at their degree of intellectual development. In our opinion it is one intimately ■connected with ethnology or general ethnography. Mr. Tylor has written a work under the title " Primitive Culture ; or. The early History of the Human Eace," and Sir J. Lubbock one on the " Origin of Civilisation." The former clearly shows, just to take one example, that morality is synonymous with general conduct, that it is always utilitarian, that it varies in different peoples, conformably to their wants, that originally restricted within the narrow limits of the family, then of the tribe, it has extended to greater confederacies ; that, in a word, it is progressive. Suffice it to say that ideas of morality may give ethnic characters but not differential physiolo- gical characters between races, at least until a new order of such should arise. The knowledge of religious beliefs advances in the same way. By the comparison of the fables and allegories upon which all systems of mythology are based, it traces back its inquiries, as is done with regard to language, to the remote period when peoples came in contact with one another, and consequently separates the acquired character from that which is inherent. It has a still wider range : it takes a retrospective view of the various phases of those intellectual qualities of which races have mutually become the possessors, as well as of that which they have acquired by the simple and natural development of the faculties inherent in Man generally. The problem of the differential characters of human races dependent on their special cerebral organisation, will be in this way simplified, and then no doubt we shall be able really to say that the modes of activity of the brain furnish distinctive characters, in the same way as the shape of the skuU or the character of the hair. The only objection would be that their varieties eould not be measured with the compass. 412 PATHOLOGICAL CHARACTERS. [Chap. vin. The "Bibliotlieque des Sciences Contemporaines" has in the press a volume by M. Girard de Eialle, which treats on Comparative Mythology. We doubt not that the subject of the successive and mutual phases of perfection through which the human races have passed, both intellectually and socially, wUl be fully considered in this volume. PatJioIogical OJiaracters. Pathological characters are a deviation from the physiological, and, like them, have to do with the living subject. All morbid peculiarities which certain races, to the exclusion of certain other races, present, may be classed under this head. It is not our present intention to treat of this subject, which has rather to do with medicine. We should have to consider, at the outset, the progress and the development of diseases, depending, on the one hand, on telluric and atmospheric conditions, and, on the other, on race. With respect to the former, we enunciated, some sixteen years ago, a fact which was more or less confirmed by others, namely, that the mortality after capital operations in the English hospitals was less by one-half than in the French. We attributed it to a better diet, to their better sanitary arrangements, and to their superior management. There was but one serious objection offered to our statement. M. Velpeau, with his wonderful acumen, made reply, at the Academy of Medicine, that the flesh of the English and of the Erenoh differed ; in other words, that the reaction after operations was not the same in both races. It is, in effect, an anthropological character. The immunity of negroes and their cross-breeds from yellow fever ; the few cases of hepatitis in Senegal as compared with those among Europeans ; their greater predisposition, on the contrary, to plague, are other examples of the same kind. According to M. Ob^d^nare, the inhabitants of Eome are almost proof against malarial fever, whUe Germans residing there are very sensitive to its influence. These pathological cha- racters form an entirely new subject, to which we beg to direct the attention of our naval surgeons. In treatises on pathology we find Chap. Till.] CAUSES OF THE EXTINCTION OF RACES. 413 much as to the influence of age, sex, and temperament on disease, as well as concise descriptions of affections peculiar to certain countries, but almost nothing as to the influence of race properly so called. This is a gap which must be filled up.* Apropos of the skin of the negro, discussion has arisen with regard to the colour of cicatrices after wounds. The question has now been settled. After deep wounds the cicatrices are whitish, and when superficial they are blacker than the adjoining skin. The causes of the extinction of races may be considered here. "Whether rapid, slow, or scarcely perceptible, this progressive ex- tinction in the presence of new races, relatively superior, and differing in morals and civilisation, is an acknowledged fact. That it should be so in tribes as truly savage as the Obongos of Du Chaillu, and the Australians of Port King George, described by Scott K"ind, is not surprising ; but that the phenomena should be repeated among the Polynesians, who are far from being an inferior race, in the North American Indians, and in the Arabs of Algeria, is very remarkable. The same influences, however, are at work in each case; some morbid, others physiological, aU capable of being summed up in one word. Among morbid causes are included diseases new to the country, and more or less contagious, which Europeans bring with them in the same way as they did the dog- * A volume might be ■written respecting the comparative pathological characters of the two races, the negro and the white, as seen in the United States. OiEcial documents might he furnished for the statistical part of the work. Thus, as regards the relative frequency of mania and idiotcy, tables like the following are full of interest : Proportion per 1000. Mania. Idiotcy. 19,555,000 Whites 0-76 0-73 434,000 Freed negroes 071 0-81 3,204,000 Negro slaves ... 010 0-37 It proves that social influence predominates over the influence of race : a brain having nothing to think about is less exposed to insanity than one having to battle with the necessities of the social condition. This is quite natural : an organ which has much work to do is more likely to become deranged than one which does not work at all. 414 CAUSES OF THE EXTIKCTION OF EACBS. [Chap. Tin. grass to La Plata, and as tlie Americans recently gave France tlie phylloxera. For example, the small-pox, imported into St. Domingo in 1518, into Iceland in 1707, into Greenland in 1732, into the Cape of Good Hope in 1748 (Boudin), and which, when it first made its appearance in Australia, in 1788, almost annihilated the curious trihe of Port Jackson, now called Sydney; the measles, which has just destroyed half the population of the Fiji Islands ; scarlatina, syphilis, the severity of which, however, has been exaggerated ; alcoholism, in aU. its forms, which is propagated by imitation, and easily assumes an epidemic character. Among physiological causes are a sudden change of habits, the impossibility for the native, under these circumstances, to supply his necessities as heretofore, and nostalgia combined with ansemia, which are the results of this change. Before the arrival of Europeans, the Australians were in possession of immense territories, where game was, as it were, preserved, and where food was always at hand. The kangaroo occupied the same place as the reindeer did formerly among our own ancient populations of the P&igord, or as the horse among those of Solutrd They had, moreover, vast natural pastures and cultivated grounds, the harvest from which they gathered regularly every year. They were agriculturists and sheep farmers, without having the cares and anxieties of those occupations. All at once they .were driven from their hunting-fields and pasturages, the kangaroos were put to flight before the musket, and before a generation had passed they were compelled altogether to change their habits and mode of life {Report of the Adelaide, South Australia, Commission). Their life was an easy one when thej» had a vast extent of country at their command ; but when it became circumscribed in extent, and they had to contend with aU the obstacles of civilisation, it became insupportable. With insufficient food, they in their naked state were unable to withstand the cold, in addition to which, dejection and sadness at finding themselves, under subjugation iu a country of which they had been the sole proprietors, opened the door for the ingress of every kind of disease, as well as for every sort of vice. Under these circumstances they were generally carried off by phthisis. Chap, tiii.] CAUSES OF THE EXTINCTION OP BACES. 415- Ifow, in Australia, as in so many other places, the population was sparse in proportion to the extent of the country. The scarcity of women, the regular practice of infanticide, and the frequency of accidents which are inseparable from savage life, together with ciieumstanoes we hare already mentioned, helped to keep it down. Moreover, there are two iafluences at work in producing disease : an external, morhid or accidental, and an internal, caused by a want of power of resistance in the system. It is this latter which plays the principal part among savages. There is therefore nothing mysterious in this extinction of race. An old Namaqua woman, to all appearance a centenarian, when asked, hy Barrow if she remembered the period prior to that when the Dutch took posses- sion of the country, replied : " I have good reason to remember it, for at that time we did not know what it was to have an empty belly, now we can hardly get a mouthful." Under a less cruel form the cause of the progressive diminution of a race is always the same. That portion of the race which secures the better part of the resources of the country has the advantage over the other which does not follow the movement. The Arabs are long Uved in Arabia, because they are in undisputed possession of the country ; they decrease in Algeria, because they meet with opposition, and therefore cannot enjoy their pastoral life uninterruptedly. They instinctively retrograde in the Desert of Sahara, Kke the Americans in the Eocky Mountains, ilie Berbers, on the contrary, with whom our civilised mode of life thoroughly agrees, thrive well there. In fine, it is the law of adaptation to external conditions, whatever they may be, whether physical or moral, and the mechanism of progress. The regular and progressive increase of the populations, such as we see now going on in Europe, is not noticed in the savage state, as among the negroes of Africa, nor in the barbarous state, as it was in Europe before our present era. In both these cases, the- number of premature deaths by murder and accident, as well as by preventable disease, has considerably increased, and the balance as between births and deaths remains in reality stationary, barring. 416 CAtrSES Off THE EXTINCTION OF EAOBS. [Chap. viii. certain oscillations annually, either upwards or dotvnwards. In Africa at tlie present time, where the influence of the European has not yet been felt, there are negro tribes which are becoming extinct without any apparent reason, without any change in their external condition, and almost without having become reduced in number by war. It is not surprising therefore, another unfavour- able condition being added, such as the necessity of suddenly changing their habits of eating, sleeping, walking, method of clothing, &o., that the equilibrium should be destroyed, and that death should get the upper hand. At the present rate of increase of European population and of emigration, the earth will soon be overcrowded, to their advantage. There are, however, causes which tend to the rapid destruction of races. The Tasmanians have been exterminated to the last man, and their half-breeds alone remain. The English die out in India, and the Dutch in Malacca, because they are unable to acclimate in those countries. The Esquimaux in the northern part of America are becoming extinct because their country is gradually becoming colder, and existence in it is becoming impossible. Captain Hall says the Esquimaux die more from phthisis than from aU other diseases put together. Among the most celebrated races which have become recently extinct from natural causes, we may mention the Charruas, the Caribs (1), the blacks of California, and among the first to disappear, the natives of Eastei Island, the Kamskatdales, the Esquimaux, and the Makololos, &c. Chap, ix.] ETHNIC CHAEACTEES. 417 CHAPTEE IX. ETHNIC, LINGUISTIC, HISTOEICAL, ARCH^OLOGICAL CHARAOTBRS : THEIR VALUE — PREHISTORIC RACES OUR AI^CESTORS OP THE ROUGH AND POLISHED STONE PERIOD. The two series of anatomical and physiological characters which we have been describing are really the only ones belonging to the province of Natural History, the only ones upon which one can directly rely in order to determine the number as well as the nature of the principal divisions of the human family. Those of which it remains for us to speak, to which we shall continue to give the name of characters, are of an entirely different order. They are indications derived from various sources, and may be compared with those which one would seek from a breeder in order to establish the genealogy of a breed of dogs or cattle. But as regards Man, the sources are more varied and of a nobler character. His customs, his language, his migrations, the relics of his remote industry — all these are to be considered before we can solve the problem of the relationship of each of his races. In a certain point of view, the characters included under the terms " ethnic " and " linguistic " should have found a place in the previous chapter, under the title of simple intellectual manifesta- tions of the physical organisation of the individual regarded as a type of the race. But if mode of living, laws, and language are inherent in the race, they depend much more on such an union as the chance of events establishes. Eace and people are, in fact, two terms having no relation to each other; the former is' an anthropological group, the latter a social group. Hitherto we have only considered races; now we shall speak of peoples, and shaU. begin with ethnic characters par excellence. JEthnie Characters. By ethnic characters are understood all those things which result from the association of men with each other, whatever their cause, 2 B 418 ETHNIC CHARACTBKS. [Chap. ix. such, as want of society, interest, caprice, or warlike passion. National unity, as we see it realised in the highest degree in France, and the federation of autonomous provinces, as in the United States, are the highest forms of this enlightened association. The small tribes of Todas, in which aU the members are united by ties of kindred, and where association is synonymous with family, are an example of the lowest degree of an opposite character. In each case a greater or less share of liberty is left to the in- dividual, and authority is confided to a chief or to an assembly of delegates. The democratic organisation of the Kabyls of Algeria, the authoritative institutions of the nomad Arab, the system of the Australians, who settle their disputes in assemblies ' periodically called together, termed corrohories, are other examples of this. Very rarely is there any trace of organisation of any kind, as among the Australians of Port King George, described by Scott Nind, and the Obongos of Du Chaillu. The object of association is defence against the common enemy, and mutual support in the battle of life. Its result is the establishment of customs, regu- lations, and subsequently of laws, %vritten, or transmitted verbally from generation to generation. The idea of an equal participation in the expenses and pleasures of life comes at a later period, tardQy followed by a notion of morality, as the term is understood by Europeans, namely, the protection of the weak and the infirm, and the equal right of all to the "banquet of life." It, how- ever, continues everywhere among pariahs, the oppressed, the down-trodden, and perhaps among civilised nations — but with them more as a matter of habit. The principal object of democracy, the highest conception of morality, is to dispel these inequalities. As a sequel to laws and customs, and with a view to public utility, there become developed — we know not how — a number of customs, either of a rational or a ridiculous character, corresponding to some innate weakness of the human machine. Such are the rites associated with the great epochs of life, with birth, puberty, marriage, parturition, and death ; the custom of tattooing, of mutilating the teeth, the nose, the ears, the feet, the body, Chap, ix.] ETHNIC CHARACTEES. 419 the head, &c. ; the ceremonies pertaining to religion, to memorials, whether of glory or calamity, &c. It is to the social state again that all our inquiries are directed respecting implements, arms, methods- of navigation, the character of dwellings, and the kind of food selected by different peoples. It is here also, as well as in reference to intellectual capahiUty, that we place the description of the pursuits of fishing, hunting, agriculture, trade, and commerce; and lastly the Uterary, artistic, and musical pro- ductions characterising each nation. If races are naturally predis- posed to a particular mode of life, peoples do not often adopt it unless to follow the example of, and owing to their contact with, -other peoples. Such are the materials which ethnography has to employ. Ethnography, then, is the description of each people, as now existing, or in the successive phases of its development, of its laws and customs, its language, its origin, and its relationships. Ethno- logy treats of the same subject, but from a higher point of view, by attaching itself to ordinary traits of character, and seeking to determine the laws which preside over the relations and changes of peoples, and the development of their customs and institutions. Both the one and the other powerfully contribute to the progress of Anthropology, but should, strictly speaking, be separated from it. (See page 7, et seq.). Among these ethnological, or, for greater brevity, ethnic cha- racters, some have but httle importance when taken together, while others possess an individual value, and are useful as affording us a knowledge of past, and consequently of present, ties of kindred, and a power of determining the anthropological elements which ■enter into the composition of each people. Cannihalism, for example, has existed almost universally among races living in a savage state, sometimes as a means of subsistence, as among the Monbouttons and some other African tribes — among whom shambles for human flesh are openly kept ; sometimes with the idea of appropriating to themselves the qualities of the deceased. It is practised after a battle as a religious ceremony, ■or spontaneously in time of peace. Cannibalism therefore, by 2 E 2 420 ETHNIC CHAKACTEES. [Chap. ix. itself, does not furnish us with any means of discovering the pacific arrangements which have taken place at a certain moment between two peoples ; but from the circumstances which have occurred, and from subsequent proceedings, it may go- some way towards it. So the custom of erecting rough stone monuments as records of important events, or for the purpose of receiving the remains of those to whom honour has been paid when living. Stones set upright, or placed one upon another, or forming chambers, have been met with in almost every country. They are stiU constructed in India. The present race of Kabyls of the Djurjura sometimes set up stones in a circle on the spot on which they hold their great federative assemblies. The marble slabs which we place in. our cemeteries are a rehc of this natural disposition in Man to. appropriate that material which appears to him to be the most durable for the purpose of making of it a commemorative memo- rial. According to the peculiar form of these constructions, so. are they classed imder different groups. It is quite clear that the dolmens and cromlechs of Denmark, France, England, Portugal,, and Algeria have been the conception of one and the same periodi of civUisation, while those of the Deccan, the Assam, and the- provinces to the south of the Brahmapootra have been that of another. In all countries of the world Man made use of flint weapons- for purposes of warfare, before he became acquainted with metals. In Patagonia, in the Sahara, in Oceania, as well as in Europe, they are found in great numbers, either on the surface or embedded in the earth. Frequently even their shapes are alike in countries which, as far as we know, have not been in com- munication with each other from the remotest periods. Moreover, from the particular way in which these flints are worked we are able to form a judgment as to the relations which have existed between tribes far removed from one another. Even the sub- stance of the flint itself furnishes useful sources of information. The use of the bow and arrow, the lance, the shield, as observed in various parts of the globe, is simply a question of ordinary Chap, ix.] ETHNIC CHAEACTEBS. 421. interest. So witli the boomerang, wHcli has been met with almost identical in shape both in Australia, in the Deccan, in Egypt, and in America. It is in use throughout the entire extent of the first- mentioned country ; but it is not found either in ISTew Guinea or in Polynesia; while the bow and arrow, so common in these latter countries, have disappeared in AustraUa, proving that the natives have not been in contiguity sufficiently long for the industry of either one to have become influenced by that of the other. In the Deccan, the bow and arrow are in use at the present moment, whence we come to the conclusion that the Australians must have brought it from that country, at least, that the reverse is not the case. Various considerations make us lean to the former hypothesis. It must be thoroughly understood that these circumstances ia no way estabKsh a relationship between two races. They simply indicate that two peoples, having the same custom or the same industry, have probably been previously in contact. Consequently they may be derived the one from the other, have descended from one and the same stock, or have crossed. The Todas of the jSTUgherries Kve an altogether exceptional life : they have a special worship ; they subsist on milk and pulse ; and transform their dairies into temples. It is the duty of the priest to perform the operation of milking the buffaloes, and to look after the apportionment of the milk ; and the little beU hung round the neck of the principal cow is a sacred symbol. As far as we know no similar kind of worship has been found anywhere ; but it is ■evident that it might be discovered among some other solitary people of India or of distant parts of Asia. It would then become probable that they had lived together, and possible that they might be of one and the same race. The artificial deformation of the head shows also how much may be gathered from ethnic customs. From the Caucasus to France we come on the track of peoples who practised it after one particular fashion. On the other hand, in America, previous to our era, we see a people who also practised deformation of the head of so special a character, that we are able to trace all the spots at which it sojourned ia its journeyings through both ISTorth and South 422 ETHNIC CHARACTERS. [Chap. ix. Ajnerica. "We frequently discover a deformation produced in anotlier way alongside of, and even among, this same people. What relation is there between the two races, hoth having one and the same custom, hut that custom modified ia two altogether different ways 1 By supposing them to he the issue of one and the same stock at a very remote period, would there be any relation between this stock and the European part of the Caucasus 1 The question cannot he solved ; but further researches may clear up the matter. Already in Asia we see other deformations showing them- selves, as if to establish another link between Europe and the Americas. The practice of scalping is one very extensively carried on in Iforth America, where each tribe of Indians has its special method. Duncan also found it employed in Africa in 1845. The ancient Scythians {Burton), the ancient Germans, the Anglo-Saxons, and even the Erench ia 879, according to the Abb6 Domenech, had recourse to it. The institution of caste, regularly established in India, and found in Austraha in. a rudimentary state, as well as in some parts of the Malay peninsula ; the custom of tatooing with the needle in some countries, and by scarifying in others, as well as the different marks adopted by each tribe; the taboo, so national among the Polynesians that it makes one suspicious whence this custom originated ; the universal practice of chewing the betel-nut in the Malay archipelago — are so many ethnic characters for our consideration. There are a number of most singular practices con- nected with the period of puberty, or adopted in infancy, and which axe designated by the general term ethnic mutilations. But of all customs, the most varied have reference to the method of disposing of the dead. Besides the dolmens, there are the tumuli of ancient Siberia, of North America, and of the Gauls of the Bronze Age ; the canoe of the Patagonians ; the practice of embalming of the Peruvians, the Guanchas, and the Egyptians. Sometimes the corpse is burnt, or simply smoked, or eaten by the relatives. Sometimes it is allowed to putrefy on the branch of a tree, or left to vultures on a lofty wicker structure or Chap, ix.] LINGUISTIC CHAKACTERS. 423 on an exposed tower, as among the Parsees, &c. Sometimes we see tlie bones prepared, and hung round the necks of relatives, as among the Andamans ; or the head only, with the face pre- served with its usual expression (chanchas), as among the Jivaros Indians. But it is not our purpose to describe the general subject of ethnic characters. This sketch, therefore, must suffice, inasmuch as a treatise on ethnology about to be published iu the " Bibliothfeque des Sciences Contemporaines " wiU, no doubt, treat of them in detail. Linguistic characters are one of the most valuable sources of information connected with Anthropology. Linguistics is the comparative study of the elements of each language, as philology is the comparative study of the literary productions of a language. The two fundamental points upon which the former bears are the vocabulary and the grammar — their present state, their derivation, there origin. Every language has passed through three conditions, has had three phases, before its arrival at completeness. Some languages have passed through these rapidly ; others, after continuing for a lengthened period, have stopped at the first or second stage of their development. Hence we have three types of language — monosyllabic, polysyllabic or agglutinative, and inflective languages. The first are represented by the Chinese and its dialects; the second by the idioms of the American, Basque, Berber, MongoKan, Finnish, &c. ; the third by the Semitic and Aryan languages. Our European languages belong, with about two exceptions, to this last class. By an analysis of vocabularies and especially of root-words, by a comparison of grammatical forms and constructions, one of the first results of linguistics has been to divide the eight hundred known languages, whether dead or living, into families ; these again being subdivided into genera and species according to their degree of resemblance and afiinity. Some of these families include but one known genus, as the Basque ; in others there are a great number of genera, as in the Uralo-Altaic or Turanian, which is divided into the 424 LINGUISTIC CHARACTERS. [Chap. ix. Samdyed, the Fin, the Turk, the Mongol, and the Tungus languages, and each of these into diflferent dialects. Some are so perfectly- distinct in their mechanism and in their constituent elements — as the Indo-European or Aryan, and the Syro-Axahic or Semitic, in spite of all the attempts of specialists to find in them points of contact — that they give one the idea that at the time of their formation the races which spoke them lived absolutely separated, without having any communication with other races. M. Eenan states the fact, and goes no farther. M. Chav^e is more definite. He says : " We might put Semitic children and Indo-European children apart, who had been taught by deaf-mutes, and we should find that the former would naturally speak a Semitic language, the latter an Aryan language." "Whence the conclusion that the type of language is independent of the will of Man, and the inevitable product of his cerebral organisation. The argument is considerably in favour of the polygenistic doctrine. At the moment when Man acquired the dignity of Man by the acquisition of language, he was dispersed in groups or distinct races on the surface of the globe. N"ow the number of these irreducible languages is enormous, without speaking of those which have become altogether extinct. The question as to the precursor of these races remains untouched, and does not belong to linguistics. Another result of the distribution of languages by families, is its application to the classification of races. We must not lay too much stress on this. Languages, like systems of mythology, methods of numeration, and all ethnic customs, often continue in the centre whence they have taken their origin, and have greater chances of being per- petuated in such centre, though they frequently change it. They are transmitted from one race to another, or from one people to another, in whole or in part, especially when the language of the invader is a more perfect one, and corresponds better with his new habits. Words having relation with ideas recently acquired are the first to pass away, the old ones become modified, then changes in the grammar take place. Some groups of the vanquished people resist more. Protected Chap, ix.] LINGUISTIC CHARACTERS. 425 by their customs, their spirit of independence, or by their settling •down in obscure places, they retain their idiom for a long period ; but foreign influence continuing, whether friendly, hostile, or enlightened, their language in time yields and becomes absorbed. There is in fact a struggle. The Pranks of Neustria, less civUised than the Gallo-Eomans, were not able to force their language upon them ; on the contrary, they lost their own. The soldiers of Eollo, less than a hundred years after the cession of Normandy, spote nothing but French. Their descendants were unable to commu- nicate the French language to England at the time of the iuvasion of William the Conqueror. The Saxons, on the contrary, five or six centuries previously, not only had taken possession of England, but had forced their language on its semi-barbarous inhabitants, upon whom the Eomans had only made a passing impression. In these cases, number was everything. With us, on the contrary, as regards the influence of the Eomans, it was their civilisation which decided the point. The Celtic language has been progres- sively latinised throughout. We do not now find traces of it except among the peasants living out of the usual path of civil- isation. The Celtic language itself was not autochthonous in Gaul, it had been brought from the East by a different race. That which had preceded it was the Euskarian language, vestiges of which are found in the geograjjhical names dispersed through Spain in ancient Aquitania, and as far as into Corsica, Sardinia, and Sicily, according to Humboldt; this is the present Basque language. M. Broca is disposed to think that its area extended at a remote period over the whole of Western Europe up to the point towards the east where it meets with the Ein languages. The languages now used by the peoples scattered over the globe are not therefore necessarily those which they spoke originally. The community of language between two peoples, or even between two races, determined by their physical traits, does iiot show that there was any kindred or connection between them, but simply that they had participated in the same lot. The Yakuts of the banks of the Lena in features pass for Mongols, and speak a Turk language. The Voguls and the Hungarians both speak a Fin 426 ETHNIC CHAEACTEES. [Chap. ix. language ; the former, as to physique, are Mongols, and the latter Europeans, among the upper classes. The Belgians speak Latin, and have remained Kymris. Linguists include under the name of Kaffirs aU the peoples speaking the Bantou languages, as the Amazulus of Kaffraria, the Makololos of the Zambesi, the Mpon- gwes of the Gaboon ; their types however are different. Evidently a conquering people, speaking the Bantou, has become scattered through the whole of these various negro tribes, and has bequeathed to them their language. It is for Anthropology to separate them. la short, the characters derived from linguistics furnish only "indications, and not positive information," to quote M. Brooa. They are not permanent, and simply teach us one of the phases which the history of races has passed through. They are valuable in. the same way as ethnic and archaeological characters, but are not to be placed in the same category as anatomical and physio- logical characters, which are perpetuated in spite of crossing and the influence of external conditions. In a word, they frequently concern peoples and not races. Certain of their elements more or less resist absorption however. The vocabulary is the first altered, grammatical forms and all that which might be called the genius of the language remain to the last. Eor further detail we would refer to the classification of races according to linguistics, published by Ered. Miiller in kis " Ethnographie G^n&ale," and especially to the volume " Linguistique " (2nd edition) of the " Biblioth^que des Sciences Contemporaines," the author of which, M.

In what way have these races been brought into close contact with one another or succeeded at one particular poiuf! What struggles have they had to sustain, what examples to follow, how have they become commingled, and what remains of the most ancient of them? Such are, in effect, the problems which are incessantly presented to the anthropologist when called upon to settle the physical and even the biological characters of races. Direct sources of information are happily sufficiently numerous. Besides those we have already examined, we have written history, tradition, and all connected therewith — heroic poems, books of devotion, songs, een collected iu the Samoyed territory, hut they may belong to other races.

The nose is short, -wide, and flat, thin, at the extremity, the nostrils being dilated. They are mesorrhinians (51 "47), and have an arrangement of the lower border of the nasal aperture and of the vomer which is almost characteristic. The cheek-bones are wide and prominent, and the face is almost as biroad as it is long {Van Leent). The profile is straight, the interval between the orbits wide and flattened, the superciLiary arches united, and almost imperceptible. The forehead, says Pickering, is depressed and receding in the Mongols, high and well formed in the Malay. The occiput, on the contrary, is flat, vertical, and does not pass beyond the Hne of the neck. The mouth is large, the lips are thick, and their prognathism is the greatest that has been met with in the yeUow races (69 -S). The teeth are of a bluish-black colour, and corroded from chewing betel, of which they make constant use. They are brachycephalic. In twenty-nine Javanese examined by M. Broca, the mean index was 81 'G. Lastly, they are very short of stature, slim, and moderately muscular. M. Van Leent speaks of two sorts of Malays, some similar to the yellow races we have described, others being a mixture of Caucasian features. The Battaks of Sumatra, from whom this sub-race is named, the Macassars and Bugis of Celebes, the Dyaks of Borneo, &c., are among the latter. The Battaks are better buUt, more muscular, and taller than the Malays previously spoken of. Their skin is of a lighter brown, the hair fine and black, some- times chestnut, the beard moderately thick, the nose straight, rather thin, less flat. The cheek-bones are less prominent, the face long, the mouth somewhat small, the lips less thick, the occiput round. It would be interesting to know whether this particular "type corresponded with those dolichocephalic skulls which we find labelled in our collections under the same name as the Malays before spoken of. It would also be desirable to find out whether it is not derived from India.* * See " The Malay Archipelago," by A. E. Wallace, 2 vols., London, 1859 ; " Geographie Medicale des Possessions Neerlandaises des Lides Orientales," by Van Leent, in " Arch. Med. Nav.," Paris, 1847, &c. 478 POLYNESIAN TYPE. [Chap. xi. Polynesian Type. The Polynesian, type approaclies the Malay, and must be sepa- rated from the Micronesian type. It extends from the Tonga Islands and New Zealand to Easter Island in the Pacific. The Kanaka or Polynesian race originated, according to M. de Quatre- fages, in the island of Booroo, situated to the west of Ceram, one of the Moluccas. Its first station was the Tonga and Samoan Archipelago, whence it was dispersed. It made its appearance at the heginniug of the fifth century lq the Marquesas Islands — in 1100 at Tahiti, in 1200 at Earotonga, in 1500 ia ISTew Zealand, and in 1700 in the Chatham Islands. Its first known migrations took place therefore into Malaisia a thousand years before any mention is made there of the Malays. The two races are looked upon as one by linguists, who speak of them as the Malayo- Polynesians. Moreover there is much reason for believing that the South Americans have some relation to the Polynesians. The Polynesian should be studied in the Eastern Islands, where he is more detached from the Melanesian element. He is mesati- cephalie. The norma verticalis of the skull exhibits an oval, swelling out on a level with the parietal bosses. The vault is generally occupied by a crest, the two sides of which incline like the roof of a house, or are hollowed out in wide channels, after which come the parietal protuberances ; this latter arrangement is termed keel-shaped (en carhne). His megasemic orbits place him in the same group as the Chinese, the Malays, and Americans. The Kanakas of the Owhyhee Islands have the highest orbital index that M. Broca has observed (95'4). He is mesorrhinian (49-3). His sub-nasal prognathism of 68 degrees in New Zealand, 70 '9 in the Marquesas Islands, and 75 at Tahiti, is evidence of the influence of the yeUow and black populations with which he has been mingled. But as these crosses would only increase his prognathism, and as we cannot find any neighbouring race which could cause it to diminish, we must come to the conclusion that the principle of this diminution is to be found within himself. The primitive Polynesian, therefore. Chap, xi.] AMERICAN TYPE. 479' was not prognathous ; at least the accepted minimum index of 75 places him on the confines of the "White type. The nose of the Polynesian, called by some travellers short, and by others projecting, is sometimes straight, sometimes aquihne, and more nearly approaches the American than the Mongolian type ; it is wide only at the nostrils. The ma'ar bones are large, not very wide, and the face is oval, not coming within the category of those decidedly flat. The superciliary arches project but little, and the falling in of the root of the nose is not very deep, which clearly distinguishes him from the Melanesian type. The eyes are black, large, and well formed, more or less full, and not oblique. The complexion is very variable. According to some it is of mahogany colour, of others of a dull copper colour. M. Bourgarel says it is of a yellowish-olive hue, lighter sometimes than that of the Malays, especially at Tahiti Jacquiuot says it is generally tawny- yellow, mixed with more or less dark bistre. The hair is black, thick, and harsh occasionally, becoming beautifully curly by crossing -with the European. The beard of the Polynesian is scant. He is of tall stature, well bxiilt, slight, but with some tendency to obesity. The American Type. The American type is that which was most commonly met with both in I^orth and South America previously to the arrival of Europeans, the Esquimaux being put aside. "We shall describe it according to the best authors, especially Morton. The average colour of the skin is olive-brown, variously mixed with white and red, and sometimes amounting to a cinnamon colour {Nott). The hair is long, glossy, black, and stiff like horsehair. The eyebrows and eyelashes are thick, but the hair in the beard, the moustaches, and on the surface of the body is scant. The eyes are small and sunken, and the eyelids exhibit aU. the varieties observed in Asia, being sometimes contracted and oblique, at others horizontal as with us. The superciliary arches are more developed than in the Mongolian type. The nose, sometimes Asiatic, is more frequently large, prominent, bridged, and even aquiline {Gatlin). The nostrils 480 AMERICAN TYPE. [Chap. xi. are dilated. The- oheek-TDOiies are prominent, the face is round or triangular, the jaws are heavy and slightly prognathous {Nott). The mouth is large, and the teeth are vertical, strong, and but little liable to caries. If we are to rely on the method of cubic measure- ment, followed by Morton, the American skull is one of the least ■capacious of the whole human race. It is more frequently dolicho- cephalic than brachycephalic, judging from the collection at Philadelphia. That at the Museum, on the contrary, is mesati- cephalic, being caused by the mixture of brachycephaly and dolichocephaly in equal proportions. The Mexicans have an index of 78'1, the Peruvians of 78'7 {Broca). Dolichocephaly is more extensive in the north, according' to Morton, among the tribes that originally inhabited the east of the AUeghanies, and brachycephaly among those to the west of the Mississippi. The same thing occurs on the coasts of South America. The Peruvian skuUs are distinguished by their quadrangular form. A common characteristic of the Mexican populations is flattening of the posterior part of the skull which is vertical. The vertex is often pyramidal, especially when looked at from behind. The forehead is moderately broad, but low and receding, upon which Humboldt laid some stress. The orbits are quadrangular and megasemic, which is an important fact. The skeleton of the nose is mesorrhinian. Their stature is generally very much above the average of Americans, although there are some tribes in South America, as the Patagonians of the south, and the Assiniboins in the north, who are very tall, and others, as the Peruvians and some tribes in the island of Vancouver, that are rather short, proving the existence of divers elements in the American type.* To sum up : the American in his ensemble approximates to the type of the Yellow races in many important particulars. Thus : his face and nose are sometimes flat, the colour of his skin, the nature of his hair, the colour of his eyes, the slight development * See "Crania Americana," l>y Morton, Philadelphia, 1839; "Types of Mankind," Nott and Gliddon, Philadelphia, 1854. ; " L'Homme Amerioain," "by A. d'Orbiguy, 2 vols., Paris, 1859 ; article " Amerioain," hy E. Dally, in " Enoycl. des Soienoea Medic," vol. iii., 1865 j &c. Chap, xi.] AMEEICAN TYPE. 4SI and harshness of his pilous system, his small eyes with narrow palpebral apertures, his orhital megasemia, &c. Flattening of the occiput is met with also in some races of Asia. But he also ex hibits marked differences, such as his projecting, convex, and com- paratively narrow nose, his very taU stature, the smaU capacity of his cerebral cavity, and his slight prognathism. These are characteristics of races which have crossed, one of the elements being clearly Asiatic, and the other altogether special — dolicho- cephaly, the European nose, &c. The above description applies rather to Horth Americans. Nevertheless the Toltec sub-type, to which Morton refers the natives of Mexico, Peru, and 'New Granada, differs but little from them. The difficulty of American craniology arises from the fact of the existence of such extensive cranial deformations. By basing it upon them, and setting aside some rare deformations, we might however, we thiak, take out from the mass of Americans two ancient peoples who practised deformation of the head — the one in the method employed/by the Ifahuas, the other in that by the Aymaras. (See p. 183.) The Tehuelche or Patagonian type should also be set aside, and then we might take account of those singular differences of complexion, pale in the Botocudas and in the Guarani race, almost black in the ancient Cahfornians and the Charruas of Uruguay, which are now extinct. "The Calif ornians," says La P&ouse, "have a similar com- plexion to that of the negro whose hair is not woolly. Judging simply by their colour, one would imagine oneself amongst negroes in a plantation in the island of St. Domingo." " Their hair," says EoUin, " is long and very tough. Their forehead is low, the eyebrows are thick and black, the eyes black and sunken, the nose is short, and depressed at the root ; the mouth large, the malar bones are prominent, the Ups thick, and the teeth beautiful." "The Charruas," says Prichard, "belong by their colour to the Black races, or those which are nearly black, with scarcely any mixture of red tinge in them. They are upright, well-proportioned, and active ; they are of middle stature, and about an inch taller on the average than the Spaniards. They have a straight head and 2 I 482 PATAGONIAN TYPE. [Chap. xi. open foreliead, regular features, althougli the nose appears narrow and as though sunien between the eyes ; the eyebrows are scant, they haye no beard, and very little hair on other parts of the body. The hair of the head is thick, very long, glossy, and always black. Their hands and- feet are smaller than those of Europeans, and the neck of the women is less full than that of the Indian." The characteristics of these two races therefore partake more of the American Mongol element than of the one having projecting features, which we are about to describe. The Patagonian Type. The Patagonian type, or rather a certain ancient Patagonian type, requires that we should speak of it by itself. The whole popular tion being confined to one extremity of the continent, where it is shut up among mountains, there is greater probability of its being the remains of some primitive race. The Patagonians, or Tehuelches, are exactly in these conditions. Their characters, as obtained from a study of living subjects, are the following : They are very tall, the limbs and the trunk being in proportion ; the head is large, the face a long oval, the complexion olive brown, or a tone that Fitzroy compares to old mahogany ; the nose is short, broad, and flat ; the forehead bulging (fiomhe) and prominent, the superciliary arches are moderately pronounced, the chin projecting, the beard and moustaches scanty. Up to this point there is but httle difference between it and the average American type, but it specially belongs to the present race of Patagonians. Five skulls procured from the ancient encampments, or prehistoric paraderos of Patagonia, and brought to the Museum of the Laboratory of Anthropology belonging to the Ecole des Hautes Etudes, by M. Moreno, present an appearance totally distinct from aU the other American skulls in the collection. At first sight one would think they were the skulls of Esquimaux. The narrowness of the forehead, its height, its bulging at the level of the frontal bosses, the antero-posterior elongation of the cranium, its posterior part in the form of an inclined plane, and then curved round; the height Chap. XI.] PATAGONIAN TYPE. 483 •of the vertical diameter or acrooephaly, the vertical direction downwards of the sides, the elongation of the face, the projection forwards of the malar bones, the degree of prognathism, the narrow- ness of the interval between the orbits, the harmony of form between the cranium and the face — all this is Esquimau. The ieeth themselves are worn down horizontally as ia this race. But it is wanting in many of their characters. Their malar bones, looked at in profile, project forwards, and fall straight, as in the Esquimau (compare Eigs. 46 and 47) ; but looked at in front they 4o not project outwards, and are not unusually large ; whence the Fig. 47. — Patagonian type : Skull from the paraderos, from the collection of M. Moreno (Museum of the Laboratory of Anthropology of the Ecole des Hautes Etudes), oval shape of the face, described by Lieutenant Musters as that of the present Patagonian race, while the Esquimau has a fuU face and has very wide cheek-bones, and the American, barring his prominent nose, generally has it both broad and flat. The cephalic index of those five skulls is 72 '02, that is to say they are the most decidedly dolichocephalic in the world, after those of the Esqui- maux, and their prognathism is 69 '4, or less than the American, and as much or more than the Esquimaux. To make up for this, they are mesorrhinian, very nearly approaching to platyrrhinian, while the Esquimaux are the most leptorrhinian on the face of the globe. 2 I 2 4S4 RED AFRICAN TYPE. [Chap. xr. ' There is no unity of type, it is true, among the skiills from the- paraderos; there are hraohycephales to be found among them, some with deformations, and some without, showing that at that epoch the races of Patagonia were abeady numerous. But the type- that we select from them must have predominated, for the average of the twenty-seven normal skulls of M. Moreno are dolichocephalic, 75 '92. However this may he, this unexpected approximation to the Esquimaux suggests some curious questions for consideration. Are the Tehuelches the autochthonous dolichocephaKc element, which, by its crossing with a race of Asia, has given origin to the present American type 1 May not the craniological singularity of the Esquimaux, who in certain respects resemble the Samoyedes and the Mongols proper, and in others are as distinct as it is possible to be, be explained in the same way? They would be another form of cross of the same Asiatic brachycephalic element with the same autochthonous American dolichocephalic element.* A Bed Type. A Bed type, it must be admitted, exists in the centre of Africa.. The Americans are frequently designated by the title of Eed, not on account of the colour of their skin, but because they frequently paint the face in this way. It would be equally proper to call certain of the Polynesian Islanders red. In Africa also this tint is very common in the centre of the continent, from the Eed Sea to Senegal ; but it is separated in so decided a way in the midst of the surrounding black populations, that it is necessary to look upon it as a particular type. The Red African type is associated with black and glossy hair, and unfortunately is found everywhere mixed, or in close contact, with the negro popuktions. Here and there, however, it is suflS- ciently isolated, among the Foulbas for example, for its independent character to be demonstrated. Let us consider first ihs colour of the skin. * See " At Home with the Patagonians," hj G. C. Musters, London, 1871 j. "Des Cimeti^res et Paraderos de Patagonie," by P. P. Moreno, jun., in, " Eevne d'Anthrop.," vol. iil., 1874; &c. Chap, xi.] EBD AFBICAN TYPE. 485 Although, it is stated that the red colour adopted hy the ancient Egyptians in their representations of themselves on their monu- jaents was merely arbitrary, it may be asked whether they had not .some motive for this. A portion of the present race of Bar4bras of the vaUey of the NUe above the First Cataract are still of this colour, which they themselves compare to polished mahogany. In the plains of Sennaar, Caillaud has described the El Akmar, or lieds, as half-breeds, or of a peculiar caste. A considerable number of Danakil negroes on the banks of the Eed Sea are of a red copper-colour (Bochet d'Hericourt). The ancient inhabitants of the Straits of Bab-el-Mandeb are called Himyarites, which signifies red (Maury). Among the southern Tawareks, and the Tibboo Indians, they speak also of reds. The Eonga, Dor, Bongo, Kredj, and Ifyam-Ifyams of the western affluents of the Bahr-el-Ghazal have a more or less reddish complexion mixed with black. The ancient Egyptians moreover were not ignorant of the existence of red people in the centre of Africa. Negroid people of a reddish colour are depicted on the monuments of Thebes of the 18th dynasty. At the present time negro tribes are spoken of on the banks of the Zambesi, and as far as the Congo, with this shade of colour. But the most important consideration is the fact that the Eoulba people are now flourishing in the Soudan. Known by the name of Peuls in Senegal, called Eoulahs by the Mandingoes, EeUani by the negroes of Howssa, Eellatahs by the Kanori of Bornii, and Eoullan by the Arabs, they came from the east, accord- ing to Dr. Barth, at a very remote period. They do not however appear in history until about the tenth century. At that epoch they constituted the " pale " element, which was predominant in the Ghanata kingdom to the south-west of Timbuctoo. In 1500 they were powerful in the west and south of the Sonray kingdom to the east of Timbuctoo; in 1600 they appeared in Howssa; in 1700 in Begharmi. They are shepherds and nomads, and continue to spread and propagate Islamism, without forming distinct nationaUties. It was only in 1803 that Othman dan Fodie, one of their chiefs, on his return from a pilgrimage to Mecca, united them into a community, and by force of arms imposed his authority over 486 EED AFRICAN TYPE. [Chap. xi. the greater part of Soudan. In this vast territory, which is to a, certain extent oivOised, Dr. Earth met with three principal races : (1) The autochthonous Negroes, constituting the majority, the vanquished people of the country ; (2) The Foulahs, or Foulbas- (native name), the conquerors, with red complexion and straight hair ; (3) The Arabs, traders or shepherds, who, two centuries ago,, came from the east into Bornii. This close contact everywhere of the Foulah with the negro^ explains why travellers describe them sometimes as slim and well- proportioned, with glossy hair — (Mungo Park on two occasions writes " silky hair ") — sometimes as squat and short, with wooUy hair. They often indeed take wives from among the negresses, while the reverse is rare (Barth). Among their half-breeds are noticed the Toucolors of Senegal, the Black Peuls, the Tor6des, and the Susus, these last belonging to the Mandingoes. The colour of the purest-blood Poulahs is sometimes coppery- red, sometimes of a rhubarb shade. In the country, where the natives go naked, the contrast between the two types — the on& reddish yellow, the other negroid — is very striking. The characters- of the type may be specially gathered from the western Foulahs.. The face is oval, the nose long and arched, the teeth vertical, the lips somewhat thin, the figure shm and tall, the limbs well-propor- tioned, the .extremities smaU. Dr. Barth thus describes those tO' the east of the Niger : " They have small, sharp, and open features, they are lively and intelligent ; the face is long as compared with the round negro face ; the lips not thick, the complexion copper- coloured, the hair black, long, reaching sometimes to the shoulders ; the figure upright and shm, the extremities slender, moderate corpulence." In a word, we must, in the Anthropology of Africa, take into account a special Eed type with smooth hair, approxi- mating to the European type. Being now closely intermingled with the negro races, it is no longer represented but by the pm-e- blood Eoulahs.* * " Travels and Discoveries in North, and Central Africa," by Dr. Barth,. in 1849-55. London. Chap, xii.] NEGEO TYPE. CHAPTER XII. 487 NBQEO, KAFFIR, HOTTENTOT TYPES — PAPUAIT, NEGRITO, TASMANIAN TYPES — AUSTRALIAN TYPE — CONCLUSION OF THE SUBJECT OP HUMAN RACES. The Negro Type. The Negro type, understood in its more general acceptation, is met with, in Asia, near its soutii-eastem angle, in Oceania, where it exhibits two distinct types, the Papuan and the Negrito, and in Africa, where it is divided into the Guinean, Kaffir, and Hottentot types. "We take the Guinean as hest representing the most ancient and the most classical Negro type. The northern limit of the most characteristic negro trihes ex- tends from the river Senegal, inclines to the east as far as the 10th degree of north latitude (Maury), and is lost in the region visited by Speke and Baker, where there are different tribes whose parentage is not as yet thoroughly determined. Above this line, however, in the Desert, we find an isolated negro tribe, the Tebous, or Tibboos. On its confines we meet with a regular succession of other tribes, interrupted here and there by the Eoulahs, namely : The native negroes of Adamawa, Massina, Howssa, Bormi, Beg- ha,rmi, and Dar-Piir; the Nubians of Kordofan; the ShiUucks, Pungi, and SchangaUas, close to Abyssinia; and the Nouairs, Bari, and Sere of Bahr-el-Ghazal. The western Umit of the Negro type is formed by the sea. Its principal tribes are from Senegal to Benguela, as if they had been driven to the coast, namely : The Yoloffs, Sereres, and Mandingoes of Senegambia; the Peloupas of Sierra Leone ; the Kjoumans of Liberia; the Pantis, Accras, and Ashantis of the Gold Coast ; the Mahis and Dahomeys of the Gulf of Benin; the Ibos, Makos, and Calabar of the mouth of the Niger; the Bouliis, Bakalais, and M'pongwes of the Gaboon; &c. Behind them are grouped other tribes of a better type, with somewhat clearer complexion, or slightly mixed with red. Certain 488 NEGRO TYPE. [Ohap. in. Penis of Senegamtia, tlie BamlDarras of tiie Upper Niger, and certain tribes of Fans, or Pahuins, of the Gaboon are of tbis number. The following description' specially relates to the Guinean sub-type, but may be considered as that of the Negro type in general. The skin of the negro is velvety, cool to the touch, glossy, varying from a reddish, yellowish, or bluish black to jet black. His hair and eyes are black, the sclerotic dark or yellowish, black spots are seen on the tongue, the roof of the mouth, and even under the conjunctiva. The palms of the hands and soles of the feet are lighter in colour than the rest of the body. The beard is scant, and is developed late. The body is destitute of hair, except on the pubis and in the arm-pits. The skull is dolichocephalic (73'0 on the west coast of Africa), occa- sionally mesaticephalic, and even sub-brachycephalic. Its capacity, in eighty-five Western negroes, measured by M. Broca, was 1372 cubic centimetres, or 151 cubic centimetres less than in the natives of Auvergne. The norma verticalis is of an eUiptical shape. The supra-iniac portion of the occipital is frequently projecting, its lateral portions are flat and vertical, the curved temporal lines describe an arc corresponding with the mass of temporal muscles which are inserted beneath them; the temporal shell itself is larger than that of the white. The frontal is articulated frequently with the temporal; the greater wings of the sphenoid arc consequently not articulated with the parietal. The cranial sutures are more simple than in the White type, and are obliterated sooner (Oratiolet). The squamo- temporal, and the spheno-parietal frequently form a horizontal straight line. The forehead is narrow at the base, sometimes receding and rather low, sometimes straight and bulging {homhe) at the summit. The frontal bosses are often confluent, or replaced by a single and median protuberance. The superciliary arches project but little, and are smooth, very different from the Melanesian negro, s > much so that by this the two sexes tend to resemble each other. As a result of this, the orbits are less deep, which contributes, with the slight depression of the root of the nose, and the less marked general appearance of the face, to give to the negro of Africa a less -Chap, xil] NEGRO TYPE. 489 ferocious aspect thaii to the negro of Oceania. The orbits moreover are microsomes, that is to say short from above downwards, but much less so than in the Melanesian negroes, thus helping still more "to distinguish them. The eyeballs are close to the head, and the palpebral apertures are nevertheless small and are on the same horizontal line. The space between the eyes is less flat and less large than in the Mongolian type, but more so than in the European type. The nose is developed in width at the expense of its projection ; its base is large and crushed in, owing to the softness of the cartilages, and spreads out into two divergent alse, with elliptical nostrils more or less exposed. This extremity is sometimes trUobed. The skeleton of the nose is platyrrhinian (54"78) ; the two bones proper are occasionally united, as in apes. The inferior border of the anterior aperture is obliterated, or replaced by a sort of platform, the boundary between the nasal fossse and the sub-nasal region being undefined in proportion to the very slight development of the median spine.* The face as a whole is usually long, like the cranium, but it is sometimes short and round, and then it is frequently flat. The zygomatic arches, and the malar bones have only a sHght lateral projection ; the former are more frequently cryptozygous,+ accord- ing to Blumenbach's method, than in the White type, and less frequently than in the Mongolian type. The prognathism of the negro extends within certain limits to the entire face. AH the parts of the superior maxilla contribute to it, and even the ptery- goid processes, which are drawn forward by the development of the jaw; but it is only reaUy characteristic and considerable in the sub- nasal region, and in the teeth. It frequently exists also in the lower jaw, that is to say the chin recedes, and the teeth project * Loc. cit., in " Eevae d'Anthrop.," vol. i. p. 657. f When making nse of the expressions " cryptozygous " and " phenozy- gons," as synonymons -with, the less or greater development of the zygomatic arches, it is well to remember that, with very few exceptions, when the parietal angle is negative these arches are always visible, according to the norma verticaUs. 490 KAFFIE TYPE. [Chap. xii. obliquely forwards. The teeth themselves are wider apart than ia the white races, beautifully white, yery firm and sound. Lastly, the ears are small, round, their border not well curled, the lobule &hort and scarcely detached, and the auditory opening wide. The neck is short. M. Pruner-Bey speaks of two important characters which remind one of the ape. The three curvatures of the spine are less pro- nounced in the negro than in the white ; his thorax is relatively flat from side to side, and slightly cylindrical. The shoulders, he adds, are less powerful than in the European; the umbilicus is nearer the pubis ; the ihac bones in the male are thicker and more vertical; the neck of the femur is less oblique. With respect to the proportions of the extremities, we refer the reader to pages 303, 304, et seq. The femur is less obhque, the tibia more curved, the calf of the leg high and but little developed, the heel broad and projecting, the foot long, but slightly arched, flat, and the great toe rather shorter than in the white. Negresses age very rapidly, their breasts elongate after the first pregnancy, and after- wards become flabby and pendulous. The Kafir Type. The Kaffir type, one of the highest expressions of the genera] Negro type, extends from the Zambesi to the Hottentot territories, and from the coast of Mozambique to the Atlantic Ocean. Its principal tribes are : On the west coast, the Damaras or Ovahereros ; on the east, the Amakosah; near Cape Colony, the Ama-Ziiliis and the Maciias; in the interior, on the western decKvity of the chain of the Maloutas, the Bechuanas, and the Bassoutos ; and on the Zambesi, the Makololos. Linguists, however, relying on the extension of the Bantou language, extend their boimdaries, on the one side to the Congo and even beyond, and on the other to the coast of Zanzibar, among the Suahihs. The raids made continually by the Kaffirs against the Cape Colony, and tradi tions according to which they are said to have come from the Chap. XII.] HOTTENTOT TYPE. 491 north, at a remote period, testify to their warlike spirit, and to the possibility of their previous influence at some former time. But it does not follow that they should have left their physical traits iu their course. We confine ourselves, therefore, to the hest recog- nised tribes of the south-east. The Kaffir type bears a general resemblance to the Guiuean or Ethiopian, but it is a degree less bestial. The face is longer and of somewhat oval figure, the out- lines of the head are more decided, its muscular attachments and processes more marked, the maxillary bones larger. The skin exhibits various shades of blackish brown. The hair is thick, harsh, and woolly. The nose is broad and flat {epate), the Hps thick. The palpebral openings remind us sometimes of those of the Yellow races. The odour exhaled from the skin ia all the negro tribes is stronger in the Kaffir. They are very tall, slim, and well made. Seven Kaffir skulls measured by M. BertUlon showed an average capacity, enormous for negroes, of 1453 cubic centimetres. " Their vertical diameter is considerable," adds this author. In eight similar skulls examined by M. Broca, the mean cephalic index was 72 '5, being slightly less than in the Guinean negroes. The platyrrhiny of the two types is sensibly the same (54-99 in Kaffirs). The prognathism, according to our own tables, is a little less in Kaffirs, 68-21. It would be very desirable to ascertain the type of the Makololos of the Zambesi, whose language approximates them to the Kaffirs, but who appear to differ from them in physique. Perhaps they may be the remnants of some ancient type. Un- fortimately they are rapidly decreasing.* TJie Hottentot Type. The Hottentot type, now confined to the extremity of Southern Africa, formerly extended quite as far as the 10th degree of south * See article, " Cafres," by Ch. Letoumeau, in " i^noycl. des So. Medic," 2nd series, vol. ii. ; " Die Eingeborenen Sud Africa's Ethnographish und Anatomiscli Beschrieben," by G. Fritscli, Breslau, 1873. 492 HOTTENTOT TYPE. [Chap. sii. latitude. As evidence of this, tlie geographical names in Kaffraria are stiU Hottentot. The type includes the Hottentots of the Colony, the Korannas, the iSTamaquas, the Griquas (see page 382), and the Bosjesmans. We shall specially have in view the first three. The Hottentots, or Koi-Koin, have a yellow-brown or gray skin. This character is almost an invariable one. Their long wooUy hair, which is inserted obliquely in very small tufts, approximates them to the Papuans. Their thick, broad, and prominent cheek-bones, and their small and oblique palpebral apertures, on the other hand remind one of the Chinese races {Barrow) ; their eyes are dark chestnut or black, and very wide apart. Their cranial capacity is 1290 {Broca), that is to say 82 cubic centimetres less than in the "Western negroes ; they are more dolichocephalic than these. Their narrow forehead is com- pensated for by its height, and it is frequently bulging at the height of the frontal bosses. The nose is frightfully broad and Hat, the nostrils are thick, very divergent, and exposed. Their prognathism is generally enormous, though it varies. The mouth is large, with thick projecting and turned-up lips. The chin is pointed, although supported by a receding jaw. The ears are large, and without lobule. The Hottentots have but little beard, and the body is destitute of hau". Their stature is below the average, at least in the three tribes in question, the Korannas being not quite so small, which may arise from a cross with the Kaffirs. Their joints are thick ; some of them have broad and heavy feet, but in the majority the feet and hands are somewhat small. Some are of weak frame, others squat and very muscular. Steatopyga, which is somewhat common among the women, in- creases with puberty. It is met with, here and there, throughout the whole Hottentot group, and, as we have said, as far as the regions occupied by the Somalis, where the Hottentot race is no longer to be seen. In a case mentioned by Barrow, the tremulous mass passed 14 centimetres beyond the line of the back (see page 362). This character, as well as the tablier, is only constant and of any extent in the Bosjesman tribe. The Hottentot type is, in other respects, without unity; one Chap, xii.] HOTTENTOT TYPE. 493 ■would call it an agglomeration of ancient races driven down into this extremity of the globe. Thus, fifteen of their skulls in the Museum have a sub-nasal prognathism of 73 -5, and yet we find among them three marked as Colonial Hottentots, in which it is only 80, and this one of the most favoured of the Yellow races. There are two examples of Bosjesmans, where it is 63"4, and two of ISTamaquas, as low as 58-2 and 51'3 respectively. Such dif- ferences are certain evidences of crossing. So with platyrrhinia — M. Broca found the nasal index varying from 46 to 72. Travellers agree in considering the greater number of the Bosjesmans, and some of the Namaquas, as forming a distinct type. Three characters in the former seem to favour this view : (1) The large steatopyga, which is the exception among the Hottentots and the rule with a very large number among the Bosjesmans ; (2) The tablier, in -the same way ; (3) The stature, which is much smaller than that of Hottentots. Livingstone imagined that he had seen a Bosjesman 1 -83 mfetre in height, but he was no doubt deceived by a stray Kaffir. It is certain that the Bosjesmans are the smallest race in the world, and that it is a stretch to put their mean stature at more than 1 -40 mfetre. Many traits in their skeletons have also attracted attention, such as the welding of the two bones proper of the nose into one — the obliteration of the linea aspera of the femur, as in apes. In other respects their characters and those of Hottentots are alike. For example : the hair growing in tufts of closely-twisted spirals, some millimetres in diameter, the skin of a yeUowish colour, or Kke dirty varnished oak, &c. Their facial angle varies from 64 to 70, according to Fritsch ; it is 64 in one of the Namaquas in the Museum, this being the lowest known in Man. The Bosjesman woman, known by the name of the Hottentot Yenus, who died in Paris, and whose full-length portrait in the Museum is an excellent example of this race, was considered tall by her own people. Cuvier has given a good description of her : " She had a way of pouting her lips," he says, " exactly like that we have observed in the ourang-outang." To anyone who has seen these anthropoids the simile is very expressive. "Her movements had something abrupt and fantastical about 494 HOTTENTOT TYPE. [Chap. xii. them, reminding one of those of the ape. Her lips -were monstrously large. Her ear was like that of many apes, being small, the tragus "weak, and the external border almost obliterated behind. These," he says, after having described the bones of the skeleton, " are animal characters." Agaiu : " I have never seen a human head more like an ape than that of this woman." What we said before relative to the Hottentot type throughout the whole of Southern and Eastern Africa is still more true with respect to the special Bosjesman type. The Obongos, near the banks of the Gaboon, have the same old yellow, jaune vieux complexion, the same growth of the hair in tufts as the Hottentots, and a character which is par excellence that of the Bosjesmans — smalkiess of stature. From the coast of Aden, among the SomaUs, to the mouth of the Ogobai on the west, we find races of the Bosjesman type — the lowest of the human race. The fact escaped Cuvier that this type is the most animal known, and diminishes the distance which separates the European from the anthropoid ape. What shoidd we say if the type were a pure one 1 In concluding our remarks concerning the Negro types of Africa* it should be noticed that the several divisions we have admitted among them are altogether insufficient. We have been studying the Negro as compared with the White, but without taking any great account of the distinctions between them, which are as palpable as between White or Yellow races. Thus, a,mong the black tribes of the West Coast that we have associated together under the name of Guineans, there are evidently two very distinct types — one ugly, diminutive, with large and squat limbs, and with a round or short face ; the other comparatively handsome, tall, with slender and well-proportioned limbs, and with a long face. Thus we shall have to give up the Hottentot type, and after perhaps separating the Namaquan type, keep to that of the Bosjesman. So among the KafBrs, or rather those sprung from them, extending from the * See " Travels in tlie Interior of Southern Africa," hj J.

The collection of busts of M. de Froherville is sufiicient of itself to prove that the description of the K'egro races of Africa must he altogether remodelled.* The Papuan Type. The Papuan type is distributed throughout the whole geo- graphical area called Melanesia, except ia Australia. It appears to be most pure in the Solomon Isles and the ISTew Hebrides. In the Fiji Islands, and even in ISew Caledonia, it is mingled with the Polynesian type. Its characters are the foUowing : Ordinary stature, but relatively taller than the ]S"egrito and Malay types ; the skin is black or of a chocolate colour ; the hair is black, harsh, frizzled, growing in distinct tufts, which are short and thick in early Hfe, and at a later period assume a bushy character, or like the head of a mop {tete de vadrouille), measuring thirty <5entimtoes on each side. The beard, as weU as the hair on the body, grows in the same way in tufts, but these are farther apart. They have a very dolichocephaHc skull, with the lateral walls vertical, and frequently exhibiting a median crest commencing behind the bregma, or going beyond as far as the middle of the forehead. The eyes are sunk, the sclerotics dull ; the nose is thick and wide at the base, but projecting and turned up, it is said, at least in K'ew Guinea, with the median lobule extending beyond the nostrils {Wallace). The sub-nasal prognathism is considerable, the lips thick and projecting, the jaw receding, and the face, on the whole, rather long.t The New Caledonians. The ISTew Caledonians are generally associated with the Papuan type. In reality, they are a mixed race formed of three elements ; * See " Die Nigritien," by E. Hartmann. Berlin, 1876. + See "Indian AroHpelago— Papuang," by J. W. Earl. London, 1859. 496 NEW CALEDONIAN TYPE. [Chap. xii. a Polynesian ; one whose name, Melanesian, it would be as well to allow to remain, which leaves us in no doubt as to its relationship ; and an intermediate or cross race. Out of a large number of skulls it is easy to select them; the half-breeds are in greatest number, the Melanesians tolerably numerous, and the Polynesians rare. M. Bourgarel arrives at the same result on the living subject, and describes two varieties — the black and the yellow. The former is characterised, he says, by the very dark colour of the skin, the short hair, flocculent rather than woolly (Forsier), short stature, slender limbs, flat foot, very considerable dolicho- oephaly, marked prognathism, enormous superciliary arches, vertical direction of the two lateral planes of the skull, &c. The latter has the same characters, though attenuated ; among others, taller stature, limbs better proportioned, olive-yellow complexion, longer and less woolly hair, sometimes frizzled, sides of the head round, (fee. However this may be, the present mixed or crossed race presents the following characters on examination of skulls which have been brought to Europe, and which, for the most part, are those of the original inhabitants of the Island of Pines : The cranial capacity in the adult man is 1460, and in the woman 1428, and is greater than that of the Australian and the negro, but much less than that of the White and Yellow races, especially in the man. The cephalic index of 71 "78 is as small as that of Australians, Esquimaux, and the Veddahs of Ceylon. The forehead of 9 3 '5 is much narrower than in the negroes of Africa, but less than in Australians. The nasal index clearly places it apart from aL. the Black races ; it is 53'06, that is to say very nearly mesorrhinian. The orbital index of 80 '6 approximates it ta the Australians and the prehistoric races, and separates it from the YeUow races. The prognathism is 69-8, and a little less than in the Australians and negroes of Africa, though in all it is consider- able. Simply by the arrangement of the inferior border of the nasal aperture one may always distinguish a New Caledonian from an African negro. In the former it is absolutely obliterated, and replaced by two channels of an altogether simian character, which pass down on each side in the direction of the alveolar border.

The facial angle is tbe smallest ia our tables (see Fio. 48.— A New Caledooian half-breed : Yellow variety of M. Bourgarel, from M. de la Kicherie's collection. page 286).

But what strikes one at a cursory glance in the principal type of the Island of Pines, is the coarseness of the features, and the contrast between the hoUows and prominences of the face, which gives it a ferocious appearance. The integuments would however modify these characters, as in the Tasmanian, to judge by the very beautiful photographs forwarded by M. Simon,, French consul at Sydney, and unless theyrepresent another altogether contemporaneous type, the face would be, on the contrary, full,, round, moderately long, the features, as it were, pasty, and without animation. The hair forms a thick and continuous fleece ; the nose is large, broad, and flat, the lips large and pouting, (fee. Figure 48 represents a half-breed, no doubt one of the Yellow variety. From her tall stature, her slender limbs, and her comparatively light complexion, she is Polynesian. From her deeply-sunken eyes and overhanging eyebrows, her long forearm, her slender and high calf of the leg, her projecting heel and flat foot, she is Melariesian ; from her frizzled rather than wooUy hair, she is a cross-breed.* It must be admitted, iu short, that the present Ifew Caledonian race is principally Melanesian, as the hair, as well as the features generally, testify, but that the Polynesian influence has made itself apparent, especially in the stature and the nasal index. It is to this we have aUuded whenever we have been comparing the negroes of Oceania with those of Africa. The Negrito Type. The Negrito type has been carefully defined by M. de Quatrefages.. Its present representatives are the Mincopies of the Andaman * "Des Eaces de rOceanie Fraii(;aise et en particulier de celles de la NouTelle Caledonie," by A. Bourgarel, in "Mem.

Their fundamental characters are low stature, woolly hair, black skin, and sub-brachycephaly. This last character is the most prominent. The cephalic index of five of their skulls is 82-54:. The stature of five individuals collected by M. Hamy from various authors, is, on the average, r4:7 metre. The hair of the Andaman is black, woolly, and grows iu spirally- twisted tufts, like that of Papuans, Tasmanians, and Hottentots. They have but little beard, and the skin, the reverse of the Tas- manian, is glossy and jet black. The following characters also belong to them : The forehead is full and projecting, wide as compared with that of negroes, but less so than that of Tasmanians. The face is round or quadrilateral, and rather short, the cheek-bones broad and somewhat flat. The eyes are large and round, that is to say not very well formed, and horizontal, with thick eyelashes. The nose is broad at the base, but slightly crushed in, and the nostrils are round. The sub-nasal prognathism of 70-2 in the two specimens ia the Museum is about the average of Yellow races. The lips are moderately large, and appear but little turned up for negroes ; the face is round at the bottom, and not receding. The Andamans are short and squat, though the Luzon girl, according to the drawing of Choris, is slim and well-proportioned. They have square shoulders, well-developed chest, .the trunk the same all the way down, without the slightest figure, the feet and hands moderately large, the fingers long, the .heels not projecting, the toes spread out when standing on the ground. There is but little difference in the figure between the two sexes. In fact, were it not for the haic and the complexion, the negritos would, on the whole, be moderately negroid. They at one time occupied Malacca, and probably New Guinea, and the southern extremity of Asia. But it has not been shown that the black populations of India mentioned in the Mahabarrata were negritos. Up to that time no positive statement has been made as to the presence of woolly hair in that peninsula with regard to absolutely inferior simian types. The descriptions of them given by Piddington, Eousselet, and Blond are very meagre. The only argument in favour 2 K 2 500 TASMANIAN TYPE. [Ohap. xii. of tlie negrito nature of tho autochthonous stock of India is tho existence, here and there, especially in Ceylon and the adjoining part of India, of black tribes of very low stature.* The Tasmanian Type. The Tasmanian typo, now oxtinct, is separated in a most romavlc- able manner from all the neighbouring tyju'P, negroes or others. While the fifty-four New Caledonians in the Museum have a oephalio index of 71'?, and tho twenty-seven Australians of 71 '4, that of the forty-one Polynesians is 76'3, and that of ton Tasmanianw, 7G'l. Then the norma wrUculis of Blumenbaoh leads to a siniilar result ; the vault of the cranium of Tasmaniuiis is uhaT'actc.ri.stic — it is of the keel-shaped type [en carene), at least in tho skulls in the Museum; in other, words, it has a median sagittal projection, bounded by two lateral depressions, b(!yond which are two enlargr,- monts, like the sides of a ship. , The Polynesians exhibit thjs alsd, especially those in the east, although loss marked, while it never exists either in Australians or New Caledonians, who are tho most Melanesian. Again, while the angle of alveolo-nasal prog- nathism is 69"8 in Now Caledonians, C8'2 in Australians, 73'8 in two Andamanesc, and 75-0 in Polynesians, it is 76'2 in six Tas- manians ; in other words, they are scarcely more prognathous than Europeans. With regard to the direction of tho plane of tho occipital foraruon, a character of the , first importance, wc have the same result; they must be grouped with Corsicans and Berbers, the very opposite of tho Oceanic races, Notwithstanding this, from their complexion, their hair, their platyrrhinia, their retrotissSe lips, and their little cranial capacity, they are negroes. Their other craniometrioal characters ^.re these : Greater development of the posterior cranium, which places them among the oc9ipital races of Gratiolet ; swelling out of the temporo-zygomatic regions ; forehead * See " ]5tude sur lea Minoopiea ot la Eaoe NfSgrito on gdrUiral,'' by A. de Quatrefagos, in " Revue d'Anthrop.," vol. i., 1872 ; " On tho Andaman and Andamanese," by G.

Witb regard to tbe characters in the living subject, they are : A chooolate-blaok complexion, a little less dark perhaps than that of the Australian, and less than that of the negro of Guinea ; woolly hair, growing not in one continuous fleece, but in spiral tufts, which faU down in long ringlets; the beard and tbe hair on tbe rest of the body very abimdant, as in Australians, tbe hair being flat in sections under the microscope ; small eyes, sunken, with dull sclerotics; nose broad and flat {epate), not projecting, thick, and pufiy at tbe base ; mouth large, lips thick, tbe upper especially, and turned up; chin small and re- ceding; ears oval, with a thick lobule. Their stature exhibits nothing particular to remark upon, and is below tbe average. From this it will be seen that tbe Tasmanian type is absolutely sui generis, and exhibits anomalies which cannot be otherwise accounted for. We have stated elsewhere that their skulls in tbe Museum appeared to be tbe product of a cross between the Melanesian and the Poly- nesian, but that they bad a special physiognomy of their own. By their manners and customs, the Tasmanians have some points of resemblance to tbe Andamanese.* Tlie Australian Type. The Australian type, geographically allied to the preceding, is no less paradoxical, but in another sense. It is characterised by the combination of smooth hair with negroid features. On com- paring some Tasmanian and Austraban skuUs, we at first came to the conclusion that tbe former race were physically superior. On * See " Etude sur les Tasmaniens," by Dr. Paul Topinard, in "Mem. Soc. d'Anthrop.," vol. iii., meeting of the ISth Not., 1869; "Examen des M&ures Craniometriqnes des CrS.nes Tasmaniens " of Mr. Barnard Davis, in " Eevue d'Anthrop.," vol. ii., by the same author ; " On the Osteology of the Tasmanians," by Mr. Barnard Davis, Haarlem, 1874. 502 ATJSTRALIASr TYPE. [Chap. xii. making some further measurements, -which have been since published hy M. Broca and ourselves, we thought the same ; but judging by their characters on the living subject, it is just the reverse — the Australians are superior. But is the Australian type a pure one 1 Commissioned by the Soci^t^ d' Anthropologic to deliver certain "Instructions" to travellers in Australia, -we were all at once struck with the differences between the Australians of the coast, of the low plains, and some isolated spots in the bush, on the north-west more especially, and the Australians en masse of the interior, of the high lands, and especially those of the north-eastern region. We therefore called the attention of travellers to this point, and, in particular, as to the existence of wooUy hair here and there, as mentioned by Humbron, Pickering, and Stokes. We thought that before the present race of Australians there must have existed on their continent a race much inferior still, of whom the individuals with woolly hair and the ugly deformed tribes were the descendants. Erom other considerations relating to the ethnic customs described by Mr. Staniland Wake, we were confirmed in this opinion. It is clear that the Australians might very well be the result of the cross between one race with smooth hair from some other place and a really negro and autochthonous race. The opinions expressed by Mr. Huxley are in harmony with this hypothesis. He says the Australians are identical with the ancient inhabitants of the Deccan. The features of the present blacks of India, and the characters which the Dravidian and Australian languages have in common, tend to assimilate them. The existence of the boomerang in the two coimtries, and some remnants of caste in Australia, help to support the opinion. But the state of extreme misery of the inferior Australian tribes may equally explain some of the physical differences which they present. Woolly hair appears to be now but seldom, seen. A few examples of it have been noticed in the York peninsula and the north-west point, which might be accounted for by the immigration of Papuans from Rew Guinea, and in the south by the passage over to the other side of Behring's Straits of some Tasmanians to the continent. Chap, xii.] AUSTRALIAN TYPE. 503 On tlie other hand, on studying the Austrahan skull, we notice tolerably-marked differences of type, and it is certain that the Polynesians landed at some period or other in the north-west, and the Malays in the north-east. Lastly, if the Austrahans are thorough Hindoos as regards their hair, they are Melanesians, or if you will, New Hebrideans, New Caledonian negroes, in every other respect. The question may therefore be left. We are stUI in ignorance as to whether the present Australian race took its Fig. 49. — Australian type : One of its forms. ■origin on the spot, with the characters that we admit as belonging to it, or whether, on the contrary, it was altogether constituted in Asia, or whether it is a cross race, and in that case, of what elements it is composed. However it may be, the present race of Australians have the pilous system very developed over the whole body, the hair and the beard long, tufted, black, and straight. Their complexion is a dark-chocolate black, with sometimes a tinge of red in it. They are slight, well made, and if there are travellers who have only seen caricatures of them, there are sailors who describe them as perfect models for the sculptor. The Australians have one of the smallest cranial capacities known among mankind (1'347) ; they are among the most dolichocephaUc (71-4), the most prog- 504 AUSTEALIAN TYPE. [Chap, xir, nathous (68'2), and are platyrrhinian (53'4) ; their angle of Daubenton (direction of the plane of the occipital foramen) of 6 '8° approximates them to the negro, and separates them, on the con- trary, from the Tasmanians (2'6) and the White races. They have frequently the " rafter-like " shape of the vault of the cranium,. a narrow forehead, sometimes straight, sometimes receding (two forms opposed to each other), the superciliary arches very project- ing, the superior border of the orhit jutting out above the inferior, the eyes black and sunken, the nose very hollowed out at the root, thick and broad at the base, but less crushed in than the negroes and Hottentots of Africa, and perhaps than the Yellow races.* But the most important character of all, that which warrants our setting them apart as a distinct type, is their smooth hair, con- trasted with all the most perfect negro characters. The microscope confirms this distinction. On a transverse section it holds a middle place, in M. Pruner-Bey's figures, between the more or less round shape peculiar to the Yellow and American types, and the some- what elliptical form that we meet with in the Semitic races. It is therefore far from being of the long, elliptical, and flat form peculiar to the negro of Africa, the negrito, and the Papuan. Their stature would be sufficient of itself to prove that the present race is composed of two ancient races, whose stature might have been — the one about 1-600 mfetre, the other above 1-700. The maximum and minimum observed in the male have been 2-130 and 1-447 respectively. Those which we might consider in India as of the same race are — (a) The Bhils, "black, with small horizontal eyes, and with hair in long straight skeins;" (b) The Ghounds, " black, with flat nose, thick Hps, and tufted, black, shining hair, falling down in straight skeins ; " (c) The Khounds, more or less black also ; (d) The Mahairs, " very black, superciliary arches * See " Journal of Discoveries in Central Australia in 1840-41, with an account of Aborigines," by Eyre, London, 2 vols., 1843 ; " Discoveries in Australia," by Stokes, London, 2 vols., 1848 ; " Exped. in North-West and West Australia," by G.

Last year a black of this group, a native of Poudicberry, was dis- sected in tbe Laboratory of Anthropology ; his black complexion, slightly tinged with chocolate, and bis smooth, long, and shining- hair, were very remarkable. His skeleton, as well as his bust, are now in the collection of M. Broca. Among tbe Todas of tbe Nilgberries, and, strangely enough, farther on towards tbe north, among certain of tbe Ainos, two of tbe fundamental Australian traits are met with ; namely, the very projecting superciliary arch and tbe abtmdant hair over tbe whole body — characters tbe more remark- able from tbe fact that the reverse is the rule through tbe whole of Eastern and Southern Asia. In tbe same Nilgherry bOls, situated at the junction of the western and eastern Ghauts, towards the southern extremity of the Deccan, in the desired conditions for concealing the remnants of ancient races, two of the above-men- tioned tribes especially afford matter for reflection, namely, the Korumbas and the liulas. The former have a black complexion, the hair long and wavy, black, and in tufts, tbe conjunctiva often injected, the iris dark brown (No. 1 in M. Broca's table of colours), the root of the nose hollowed out to tbe depth of 5 millimetres, the bridge of the nose depressed, the alse wide, the nostrils gaping, the jaw and the teeth prognathous. Is not this an accurate portrait of tbe Australian ? We may add that they are of low stature, like tbe Australian of the coast. It is true the beard is scanty, but exceptionally it is very abundant.* * See John Shorfct, " Memoirs on the Savage Tribes of Southern India, particularly those of the Coast and of the 3Sfilgherries," in " Transactions Ethn.

Lastly, in the west, about Madagascar, and the point of Aden, ill Africa, there are black tribes with smooth hair, or, at all events, large numbers of individuals who have it, mingled particularly among the SomaHs and the Gallas, in the region where M. Broca has an idea that some dark and not negro race, now extinct, once existed. The Himyarites, in common with the Australian type, are black, with straight hair ; but the face is long, the nose aquiline , and well shaped, and the lips thin and smaU : these are black Arabs. With regard to the Charruas and the ancient CaUfornians of America, Mr. Huxley himself would not wish to make Australoids ■oi them.* (See pages 481, 482). Cojiclusion. Our task is completed. We have passed in review the differential •characters of the Human Eaces, we have pointed out their most dis- tinctive types ; we must now return to the question which was proposed at the close of our remarks on zoological anthropology. Is the human family composed of genera, of species, or of varieties 1 In other words, what interval separates its most natural divisions t We must state, at the onset, that a classification of these divisions and subdivisions would be premature. Classification supposes a science completed, and anatomical anthropology is almost in its infancy. A certain number of groups of races which merit the title of branches, and some particular races, are thoroughly defined, but this is all. Happily it is not necessary, for the solution of our problem, that we should know their value and their dependence the one upon the other. Some being well determined under conditions in which they now present themselves to us aie amply sufiicient, and we have our choice in this respect. The sole difficulty arises from the confusion created by intermediate types, some due to crossing, others natural, and in a state of transition, such as we meet with in every degree in the animal series. Such are the Malays, the Chinese, the Dravidians, the Hottentots of the Cape, the Himyarites, * "Les Peuplea de I'Arabie M^ridionale," by Maltan, in "Zeitsohr. fiir Ethnol.," 1873. Chap, xii.] CONCLUSION. 507 the Abyssinians. Let us take, then, simple general types, as the White, the Yello-w, and the Black with woolly hair ; or particular •ones, such as those of the Scandinavian, the Semite, the Esquimau, the Mongol, the Kafiir, the Bosjesman, the Negrito. What is the distance separating them 1 Let us leave the less palpable physio- logical traits, forget that we have to do with Man, and proceed with physical characters as a naturaHst would with a mammifer. We take up a treatise on N'atural History. The genus Ursus comes before us ; it belongs to the family of Plantigrades, order Carnivora, and is composed of fifteen or sixteen species. But, as in Man, many of these divisions are doubtful, or in a state of transition ; let us put them aside in the same way, and attach ourselves to the weU-recognised types. Cuvier, the great authority in such matters, describes six principal species. The most common are the brown bear of Europe, or Ursus arctos, the black bear of North America, or Ursiis Americanus, and the white Polar bear, or Ursus maritimus. We exclude the prehistoric Cavern bear, or Ursus speloeus, from our consideration altogether. The first, says Cuvier, has the forehead convex, the hair brown, and more or less woolly in the young animal, becoming smooth with age. Its colour varies, as well as the relative length of its limbs. The second has the forehead flat, the hair black and smooth, the muzzle fawn-coloured. The third has the head long and flat, and the hair white and smooth. Ac- cording to other naturalists, the bear of Europe has the trunk shorter than that of America, the soles of the fore and hind feet shorter ; and the Polar bear, the hind-quarters higher, the muzzle tapering, and the claws less incurvated and shorter. If we are not very much mistaken, these characters neither belong to another order, nor are they more defined than those which we employ to distinguish the human types ; not only those the most widely separated from each other, but those which approximate sufiiciently to induce us at once to consider them as secondary types.

Is it not thus that we separate our blonde, brown, or red types 1 The pointed muzzle is the analogue of our prognathism, or our small and narrow jaws as compared with the large and square ones. Differences of stature, and in the proportion of the body, are met with in the human races as well as in the bear species. In a word, there is less interval, as regards characters, between the white and the brown bear than between the European and the negro. Let us take another example : The genus Bos, in which the commonest species are the ordinary ox, or JBos taurus; the aurochs, or Bos ursus ; the bison, or Bos Americanus ; the buffalo, or Bog hubalus, &c. The specific character of the first, says Cuvier, is a flat forehead, longer than it is broad, and round horns placed at the two extremities of the projecting line which separates the forehead from the occiput. The second has the bulging forehead, broader than it is high, the horns inserted below the occipital crest, the limbs tall, a pair of supplementary ribs, a sort of crisp wool which covers the head and neck of the male, and forms a short beard under the throat. The third resembles the aurochs, but its limbs, and especially its tail, are shorter. The fourth has the forehead bulging, longer than it is broad, the horns directed side- ways, and showing in front a projecting longitudinal crest, &c. These are characters of the same order as our own : The shape of the skull, the abundance of hair on such or such region, its smooth or woolly nature, the mode of growth of the horns — organs similar to the hair — the proportions of the skeleton. The most important' difference is in there being in the aurochs and the bison a pair of supplementary ribs. But steatopyga in the Bushwoman is an equivalent thing. A supplementary rib is not more astonishing, in an anatomical point of view, than that exaggerated mass of fat on the buttocks, and which corresponds, not absolutely, but to a certain extent, with the callosities of apes. Between the various species of anthropoid apes, between those of the genus chimpanzee for example, the differences are less pronounced than between the principal human races. Between the orang and the goriUa there is less distance than between the Australian and the Lap- Chap, xii.] CONCLUSION. 509 lander. "We cannot say more. The distinctive characters of the jackal and the dog, the wolf and the fox, the horse and the mule, the zehra and the qiiagga, the camel and the dromedary, are scarcely more divergent, and are frequently less, than those of our types. The blonde Swede, with fair rosy complexion, light blue eyes, slender figure, orthognathous face, and large cranial capacity, is at a prodigious distance from the negro, with the sooty black com- plexion, the yellow sclerotic, the short and wooUy hair, the prominent m.uzzle, and the projecting turned-up lips — from the Papuan, with similarly woolly hair, but long, growing in tufts, sometimes dishevelled, and forming a globular mass, much larger compara- tively than the mane of the bison — or the Bosjesman, with the yellow complexion, with lips of the orang, as Cuvier says, with nymphse reaching almost to the knee, and with deformed buttocks. On a single geographical point, a little island, what a difference there is between the Aino, with the projecting nose and long tufted hair over a great part of the body, and the Japanese, with the flat nose and smooth skin ! It is from skulls that we obtain the most startling evidence. Compare the skull of a New Caledonian of the Island of Pines, who has been exempt from crossing, one of the Namaquas of Delalande in the Museum, a certain Mongol skull brought by Dr. Martin from the desest of Gobi, a certain supposed Uzbek skuU presented by M. de Khanikoff to the Soci^te d'Anthropologie, any Esquimau skuU you please, and particularly one of those brought from Denmark to the Geo- graphical Congress — compare any of these with the skulls of ]!^ubians, of Guanches, of Arabs, or those from the Caverne de rHomme Mort. The differences are frequently most surprising, and greater than those recognised generally by naturalists between simple varieties ; they are even more in number than those whieh they admit between species. If it is so in mixed types, crossed by chance in every direction, and influenced by the external circumstances which have, been bequeathed to us after fifty or a hundred thousand years perhaps, what shall we say of the pure types, when races lived in an isolated state, like the anthropoids of the Gaboon and of Borneo, and only 510 CONCLUSION.

The platycnemic tibia, the femur a colonne, and the perforated humerus, were the appanage of pre- historic races which have disappeared, swallowed up, as it were, in "Western Europe. The sagittal crest, which made its appearance sporadically among the primitive races of the south-west of Asia, as well as steatopyga among the Somalia, is the vestige of an arrangement which has been characteristic in some ancient race- absorbed about the same period. The most animal-like example of the skulls of the Island of Pines, so different from that which we now find among the negroes of New Caledonia, and that of certain Tasmanians, are a record of themselves. But enough for the- present. Without the labour of analysis and reconstruction, it shows us directly that the anatomical and physiological contrasts between human types are greater than those admitted by naturalists between varieties, and as great as between species. The interval appears even to be greater in some cases, and to extend to that of genera. Thus, the four characters which distinguish the goat from the sheep are no other than those which separate certain great- branches of the human family. We would not deduce from this that certain human groups are genera — this is for future consideration ; but we come to the con- clusion that at any rate they are species. The three following are- in this category : (1) BrachycephaUc, with low stature, yellowish skin, broad and flat face, oblique eyes, with contracted eyelids,. hair scanty, coarse, and (on section) round; (2) Dolichocephalic, with tall stature, fair complexion, narrow face, projecting on the median hne, hair abundant, light-coloured, soft, and of somewhat elliptical form under the microscope ; (3) More doHohocephalic, with black complexion, hair flat, and rolled into spirals, very prognathous, the radius long, the buttocks prominent, the breasts (in the female) elongated, (fee.

(See page 195.) But in face of the fact that certain species of animals are also eugenesio and undoubtedly paragenesic, the objection falls to the ground. We confess that before coming to the conclusion that there is eugenesis between certain genera we must wait,* but between certain species it is beyond a doubt ; they give birth to ofispring inde- finitely fertile, without the reversion towards one of the two primitive races having yet been established. It is of little consequence, therefore, that the K'egro and White species are more or less homo- genesic ; they are no less species; for the sole reason that their differential characters have the value of those upon which we establish a basis in natural history for the creation of species. With regard to the question of monogenism or polygenism, iu the signi- fication given to it at the present day, it is absolutely foreign to the subject in debate. To sum up : The HUMAN FAMILY, the first of the ORDEE of Primates, is composed of SPECIES, or funda- mental human races, whose number and primordial characters form the subject of this the Second Portion of Anthropology. * We have spoken, at page 195, of a case of hybridity between genera, wMoh miglit have ooonrred in the Department of Aisne.

DE QUATRBFAGES POLYGENISM OP AGASSIZ — TRANSFORMISM OF LAMARCK SBLBOTION OP MR. DARWIN THEIR APPLICATION TO MAN : HIS GENEALOGY, HIS PLACE IN NATURE. With regard to the position of Man in the Mammalian series, and the dignity of his races, we come to the general conclusion that they are distiact from the other problems which the knowledge of that Man implies. It matters but little whether at a particular moment, sooner or later, the physical types had been genera, species, or varieties, and whether it is stUl so. What philosophers are curious to know is how they took their origin, whether suddenly and spontaneously at all points, or progressively and naturally from things which had pre-existed. At first naturalists and anthropologists took but little interest in all these questions. They worked without listening to dogmas taught outside their own sphere, their methods of investigation were carried on in temperate regions. According as the science of facts progressed, it became impossible for them any longer to be un- interested in the lofty views which gave to Newton and Humboldt so great a reputation, and which is not forbidden in any other branch of human knowledge. Two currents therefore are established regarding the Origin of Man leading to two different doctrines — the one orthodox, 7770720- genistic, affirming that all the human races are derived from one and the same stock, and have been produced by the influence of 2 L 2 Blfi OUUilN OK MAN. fCiiJ^"'' '• dininio and oxt.orunl oiivmnslimoos in Ww livitif Hpuotv of liino lliixl. lifts ulapsrtl siiipo t.ho cn^nlioii of tlio world, lUHMmliiij?

[^Chap. i, all of ^vMcli come from one and the same stock. Man was created in the beginning, in conditions to us unknown, by the intervention of an extraneous force, or by a supreme wO. M. d^ Quatrefages, therefore, recognises but one human species, and in deference to man's elevated rank, and his character for religiousness, he eon- cedes to him a place apart in the zoological series, under the name, proposed by Isidore G. Saiat-Hilaire, of rhgne humain. The various arguments ia favour of this doctrine have been examined in the course of this work. We merely remark that religiousness is not really peculiar to Man ; and that among men, whether individuals or races, many do not possess it; that the influence of external circumstances is but little, and does not — as far as we can see, and ia the present state of things, as Geoffroy Saint-HUaire said — succeed in producing a new physical character indefinitely transmissible ; that fecundity exclusively taking place between individuals of the same species is not the criterion of the species ; and, lastly, that the interval which physically separates the principal human types is equal to, if not sometimes greater than, that which separates and determines zoological species. The origin of species, Agassiz maintained, is lost in the obscurity of the first estab- lishment of the present state of things. Species are not strictly fijxed within certain limits, nor determined by the faculty of indivi- duals of being fertile only inter se. Human races differ as much as certain families, certain genera, or certain species. They were pro- duced, in some independent way, on eight different points of the globe, or centres, which are as distinct in their faujia as in their flora. Agassiz admitted, nevertheless, the intervention, at every phase of the history of the world, of a superior wUl, operating by virtue of a preconceived plan.* The third of these propositions, coming from a naturalist of such world-wide renown, has considerable weight ; and agrees with our own conclusions as anthropologists. As to his centres of creation, which he calls realms {des royaumes), their particular localisation is only justified, as regards some of them, by the flora and fauna * " Sketch of the Natural Provinces of the World," by Professor Agassizj- in " Types of Mankind," hy Nott and Gliddon. Philadelphia, 1854 Chap. I.] TEAiTSFOEMISM. 519 generally, but not by Man : the Australian realm for example. To his Arctic realm, apparently so proper, it may be objected that it is aow entirely peopled by men and animals wbich have been im- ported there, and that their conditions of existence were precisely identical at one time iu the centre of Prance. The doctriue of M. de Quatrefages is classical monogenism, which must be dis- tinguished from the new monogenism of which we shall speak presently : that of Agassiz is a special polygenism. Both are allied to each other, ia that they search into the secret of the formation of Man outside the known natural laws which regulate the universe. It is otherwise with the doctrine we are now about to speak of, namely — Transformism. This is of French origin. The entire honour of its introduc- tion is due to A. Lamarck, although De MaiUet and Eobinet had previously sketched out some of its traits. A species, Lamarck wrote in 1809,* varies infinitely, and, considered as regards time, does not exist. Species pass from one to the other by an infinity of transitions, both in the animal and vegetable kingdom. They originate either by transformation or divergence. By going back for ages, we thus come to a small number of primordial germs, or monads, the offspring of spontaneous generation. Man is no &- ception to this; he is the result of the slow transformation of certain apes. The ladder to which we before compared the organic king- doms only exists, he says, as regards the principal masses. Species, on the contrary, are, as it were, the isolated extremities of the branches and boughs which form each of these masses. This striking hypothesis was the offspring of Lamarck's brain, at a time when the knowledge of natujal history, palaeontology, and embryology was very imperfect, and upon which so vivid a light has since been shed. Ifothing has been added to its principle : the ways and methods of transformation have been discussed, facts of observation have been supplied, genealogical tables of animated * " PHlosophie Zoologique," \sj J. B. A. Lamarck, Profesaeur de Zoologie au Museum, Paris ; Ist edition 1809, 2nd edition 1873, in two volumes. 520 TEANSFORMISM. [Chap. i. beings have been proposed ; but the foundation has remained intact both in Prance, in Germany, and in England. Lamarck, in that he -was in advance of his time, and stood forward firmly in advocacy of his theory, showed himself to be a man of genius. The ways and methods of Lamarck may be summed up in a single sentence — the adaptation of organs to conditions of existence. Change in external circumstances, he says, obliges the animal placed in the presence of animals of greater strength, or in new conditions of life, to contract different habits, which produce an increased activity in certain organs, a diminution, or a want of exercise, in others. By virtue of the physiological law inherent in every organism, that the organ, or a certain part of the organ, diminishes or increases in proportion to the work that it performs, these organs become modified when submitted to new conditions. The internal power of the organism, dependent on the general function of nutrition which is called forth, is immense. The wants induced by external changes brought it into play. The doctrine in its entirety was too far in advance of the age to have the success which was its due. Cuvier, the advocate of the orthodox opinions of the time, had but little difficulty in stifling it in the cradle — Cuvier, who ridiculed the idea of the foundation of the Normal school, as well as the honorary title of ilkve granted by the Convention to Lac^pfede. ^Notwithstanding this, however, the doctrine had its adepts. In France — Poiret, Bory de Saint- Vincent, Geoffroy Saint-Hilaire ; abroad — Treviranus, Oken, Goethe. From the year 1818 Geoffroy Saint-Hilaire became its champion, and laid particular stress on the immediate effects on the body of external circumstances. Cuvier a second time resumed the discussion, and, in opposition to him, propounded his own doctrine on the periodical revolutions of the earth, of the renewal each time of the Flora and Fauna, and of the incessant and miraculous intervention of a creative will. The contention between these two powerful geniuses had to do with the movement which ended in the Eevolution of 1830. Authority at last had the advantage, and in France transformism was vanquished. But the number of its proselytes increased from far and wide. The last Chap, i.] DARWINISM. 521 work of Goethe was favourable to it. Botanists, especially, accepted the new doctrine — W. Herbert, P. Mathews, Lecoq, Hooker, Eafi- nesquc, Naudin. Then the geologists — Omalius d'Halloy, Keys- serling, and other savants. L. Buch, Schaffhauser, Herbert Spencer, and Lyell had abeady cleared the way, by sapping at the foundation the theory of the periodical catastrophes of Cuvier, when Charles Darwin made his appearance, in 1859. This great naturalist was not vividly impressed by the views of Xamarck. His own ideas passed through his mind during his voyage round the world in the Beagle* On his return to London, six years afterwards, he studied the results which were obtained by breeders on animals, and he devoted himself to make experiments, especially on pigeons. The subject of artificial selec- tion most occupied him, when one day he stumbled on the work " On Population," by Malthus. This was a streak of light ; the word which was to make the fortune of his theory was found — " the struggle for existence." By a singular coincidence, another English savant, Pdchard "Wallace, who had taken up his abode in Malaisia, forwarded to him at that moment a memoir, supported by facts, in which the same ideas .were set forth. But Mr. Wallace, with his task hardly entered upon, recoiled before the consequences of his labom-s when he perceived that they, of necessity, applied to Man. Charles Darwin, on the contrary, persevered, and it is with justice that his countrymen gave to his theory the name of Darwinism, a theory which should be thus defined : " Natural selection, by the struggle for existence, applied to the transformism of Lamarck." "We know that breeders and horticultiuists obtain, ahnost at will, the new forms which they desire, by first selecting from one and the same species, then from the offspring of a first cross, then from those of the next crosses, and so on, individuals possessing in the highest degree the variety required. A new species is thus de- veloped, and by dint of perseverance, fixed.

[Chap, l the primitive type wMch are oMained are very strange. They have to do with colotir, form of the head, the proportions of the skeleton, the configuration of the muscles, and even with the hahits (moeurs) of the animal. Sir John Sebright undertook to produce in three years a certain feather in a bird, and ia six years a certain form of boak or head. In this consists " artificial selection," as it is effected by the intelligent hand of Man on animals in a state of domestica- tion. But is not the same result sometimes produced naturally in wild animals ] Mr. Darwin afiirms it, by substituting for the hand of Man the chance circumstance derived from vital competition (concurrence). Competition is a general law of the universe — it is exerted between physical forces, between beings of the two kingdoms, between men, between peoples. Under the name of " struggle for existence " it is even useful ; without that, there would soon be a retardation of everything upon the face of the earth. It has been calculated that a single pair of elephants — the slowest of all animals to breed — would produce, barring aU. restraints, fifteen millions of young in five hundred years. Derham, quoted by Boudin, speaks of a woman, who died at 93 years of age, as having 1298 children, grandchildren, and grea1>grandchildren. Malthus has proved that population increases in a geometrical ratio, while the resources of that population only augment in an arithmetical ratio. The law of the stronger predominates everywhere — ^the large devour the smaL. ; those the best protected by their organisation, the best pro- vided with means of attack or of resistance to external agencies, survive the longest ; the more numerous they are, and the longer they live, the more they multiply and establish a stock in preference to those who are less favoured. Spontaneous variability is another element of the Darwinian theory. Two individuals of the same species, or of the same family, do not resemble each other in every respect ; they differ by characters of no value, or by characters which give them an ad- vantage in the struggle over those whose wants, or conditions of climate, food, and external circumstances of every sort are the same. The animal with a protective-coloured skin, that is one Ohap. I.] SELECTION. 523 like the ground upon which he is moving, will better escape his enemies. In one of Darwin's works there is a very curious ex- ample of this kind in hutterflies. The animal with the thick fur will be under more favourable circumstances at the poles, the one with the sleek skin at the equator. Every advantage acquired from birth, and therefore more easily transmissible in consequence, places the individual in a better condition for resistance to causes of destruction and to sterility. It foUows, then, that certain individuals are, as it were, selected, chosen by a natural process which replaces the agency of Man in artificial selection ; and that these individuals are precisely those who are separated the most from others by some new character. The thing being repeated for many generations, the divergences become marked, the tendency to inheritance increases, and new types are formed, farther and farther removed from the point of departure. It follows, also, that wherever an ensemble of conditions exhibits itself, which allows a divergence to be developed without being stifled by rival divergences, it will take its place in the series of beings, and possibly form one for the occupation of a zoological species. One difference between artificial and natural selection is in the time they require for a transformation to become confirmed. In the former nothing is left to chance ; matters progress rapidly, but the types are not thoroughly fixed, and readily revert to the primitive type. In the latter we must reckon by ages, chance also inter- vening, for the destruction of that which has commenced only to be completed. The results once obtained are more stable. Be- tween the methods set forth by Lamarck and those of Darwin there are important differences. As regards the former, the point of departure of transformation is in the external circumstance which modifies the way of living and creates new habits, new wants, which induce a change in the nutrition and structure of organs. Por the latter, the point of departure is in the superiority that procures for the individual some advantage m the daUy struggle. Lamarck considers that variation is effected gradually ia the course of existence. Darwin, that it appears spontaneously at birth, or rather during embryonic Ufe. To the process of selection S24 TEANSFOEMISM. [Chap. i. by vital competition, Mr. Darwin adds selection liy sexual com- petition, -whicli depends, on the will, on the choice and vitality of the individuals, and especially aifects the males.* The Germans, who have vigorously espoused the cause of transformism, particularly Hseokel, recognise two orders of methods. They give to those of the French school, including changes of life and habits, of food and climate, training, the excess or want of use of organs, the name of phenumena of direct adaptation ; and to those of the English school, that is to say, to congenital characters, the name of phenomena of indirect adaptation. En- deavours have been made to see whether there may not be other processes of formation of species. According to the doctrine of Darwin, the new character pre-exists in the germ, and depends on the influence of the parents even before conception. According to Geoffrey Saint-Hilaire, the action of climate and external circum- stances is not confined to its exercise upon the individual in the course of existence, it may equally make itself felt in the germ in progress of development, and produce varieties, sometimes monstrosities. Such would be the origin of the race of gnato oxen of La Plata. In the above processes it is only a question as to slow transformations. "We might also have sudden transforma- tions. " An accident which it is not necessary to mention," writes E. Geoffroy Saint-Hilaire, " trifling at its origin, but of incalculable importance in its effects, has been sufficient to change the inferior type of oviparous vertebrata into an ornithological type. The process of M. KoUiker would be equally an accident, taking for his point de depari the various degrees of geneagenesis and the succession of forms in the development of the embryo. He thinks that beings may produce other beings separated from their parents by characters of species, genus, and even of class. He bases his theory on that which takes place sometimes in inferior forms, and supposes, as regards the superior, that a normal egg may * " La Descendance de I'Homme et la Selection Sexuelle," by Ch.

Chap, i.] GRADATION OF FORMS. 525 go past the period of its ordinary development, and give origin ta a higher organisation. These theories and processes concern the two organic kingdoms. The limits of this work do not allow of our entering into the subject further, and we must confine ourselves to Man. Do they apply to Man, as well as to animals 1 Evidently they do, or they are false : laws are uniform. As we said in the early part of this work, the Primates form the first natural group of the order of Mammalia, thanks to a certain number of characters common to them and to the succeeding orders. Moreover, this group presents numerous points of contact with the latter, and, in the series of families of which it is composed, an ascending gradation of types is observed, becoming more and more perfect. Thus, at the bottom of the scale we have the Lemurs, some of which are allied to the Insectivora, others to the Cheiroptera, and even to the Marsupialia ; above them the Cebians, many of whose genera are lemurs in a state of transition ; then the Pitheoians, some species of which seem derived from Cebians. Afterwards, the anthropoid apes make their appearance, separated by a sensible interval, if one of them, the Gibbon, did not diminish it, owing to his numerous features of resemblance to the Pithecians. At the summit is Man, many of whose types approximate in many of their features to the Anthropoids. Their differences, indeed, may be thus summed up : (1) There are modifications of form connected with the decidedly vertical attitude of Man and the oblique attitude of the Anthropoid ; (2) The more perfect adaptation of the foot and hand to their respective functions of locomotion and prehension in Man ; (3) The volume of the brain, which is three times as large, or more, in Man, thus causincr a corresponding activity of the organ, and a proportionate development of all its functions; namely, language, observation, judgment, &c. The continuity, on the one hand, of the inferior order of Mammalia with the superior order of Primates, and in this latter of its inferior family of Lemurs with its superior famUy of Man passing through the Anthropoids more nearly akin to Man than to the Pithecians ; and, on the other hand, the continuity of certain human races with others rising higher and higher in 626 TEANSFOEMSM. [Chap. i. the scale are clearly the result of this. Moreover, between one type and another, sufficiently recognised for naturalists to make them the representatives of special groups, whether of order, family, genus, or species, some variation of the organ, or some bastard species, almost always comes in to establish the transi- tion. Natura non facit saltum. It might be said that a creative force had been at work, step by step, leaving its track behind it, and that groups are due to the periods of repose during which that force was in operation on a certain spot, with a view the better to increase the number of forms. When Lamarck supposed that Man was the issue of the chimpanzee, his mind was atten- tively engaged in observing both the family of Primates in particular and the animal kingdom in general. The rudimentary organs in Man, or vestiges of perfectly useless organs — like the ilio-csecal appendix — which are well developed in other species among the Mammalia, and the unusual appearance of organs, like the supplementary mammae, or conformations peculiar to other animal species, furnish so many arguments in favour of transfor- mation. On no other hypothesis are they to be explained. They may be phenomena of atavism, of remote reminiscences, of facts of reversion. (See page 127.) Embryology would also be favourable to the doctrine. (See page 129.) "The series of diverse forms which every individual of a species passes through," says Hseckel, " from the early dawn of his existence, is simply a short and rapid recapitulation of the series of specific midtiple forms through which his progenitors have passed, the ancestors of the existing species, during the enormous duration of the geological periods."* A series of teratological cases, entering into the arrests, and even into the perversions of development, of the embryo, are thus explained. Hare-lip, polydactilia, microcephaly, are, as it were, hesitations of the principles of evolution, attempts on its part to stop at points where it had rested in anterior forms, or to progress in other pre- viously-followed directions. Human palaeontology does not reach * " Histoire de la Cr&tion dea Etres Organises d'apr^s les Lois Natnrelles,'' fcy E. Haeckel. French translation. Paris, 1874. Chap. I.] ADAPTATION OF ORGANS. 527 back sufficiently far for us to found any arguments upon it : it should pass beyond th.e last or quaternary period. The most ancient human fossU of this period, however, is favourable to the idea of a derivation of man from the anthropoid. Direct proofs as to transformism are not wanting. In so far as Man is concerned, the matter is clear ; but rational proofs, as Geofitoy Saiut-Hilaire said, are abundant. Transformism imposes itself as a necessity : everything is as if things had thus taken place ; or man was created out of nothing, by enchantment ; or he proceeds from that which existed previously. But what are we to think as to the mode 1 Those of direct adaptation of organs to life are so rational, they are so conformable to the general laws of physiology, that it would be unwise to reject them positively. Of course we have never seen a White changed into a Black, nor smooth hair into woolly ; but in time, by passing through inter- mediate races produced by crossing, there is no proof that the phenomena might not have taken place. "We are too exacting. Prichard was anxious to prove that Whites might make their appearance spontaneously among ISTegroes. All his arguments were wrong, in that he entirely left out of sight the way in which races have become removed from place to place. But we are not at all sure that his aspirations, if better supported, might not now triumph. The brain increases in volume, and its convolutions in- crease in richness, in proportion to the degree of activity of which they are the seat, bringing in their train a series of subordinate craniological characters. Nutrition and external circumstances may in the same way cause the stature and colour of individuals to vary as well as the proportions of the body. La fonction fait I'arijane of Lamarck is a demonstrative fact. When a muscle is paralysed, it becomes atrophied, the osseous eminences in which it is inserted disappear, the skeleton becomes deformed. In persons who have lost a limb by amputation, the nerves, having become useless, progressively become atrophied from their extremity to their central point in the brain (Luys). The digestive tube is dilated, and the beUy becomes large in those who are large eaters of veo-etable food. All : the diiSculty is in the transmission of 528 TRANSFOEMISM. [Chap. i. the acquired individual character ; clearly, facts are at fault here. There is no proof, however, that the tribe of Akkas is not indehted for its diminutiveness to the fact of inheritance fixing accidental characters. If the albinos are as common among the Monbouttous as Dr. Schweinfiirth states, the question is, whether circumstances being favourable, a new species may not some day start up. Sup- posing in that country, through some catastrophe, the temperature and radiation should be suddenly lowered, many would die, but the survivors would have a better chance of thriving. In poly- dactilia, supposing crossing outside the family did not counteract inheritance, transmission, now limited to five generations, according to the facts hitherto mentioned, would certainly go beyond. Let us pass on to the methods of indirect adaptation of Mr. Darwin. Vital competition is a thing which must not be con- founded with selection. It exists, no matter how we apply it, between individuals, as between societies and races. We have before us the fact of races inferior in the struggle becoming extinct. The Charruas, the Caribs, the ancient Californians, the Tasmanians, no longer exist ; the Australians, the Negritos, the Esquimaux, are fast following them. The Polynesian, the American Indians, wiU soon be in their wake, if they have no chance of surviving except by crossing. The superior races, on the contrary, thrive and in- crease. It is easy to foretell the moment when the races which now decrease the interval between the White man and the Anthropoid shall have entirely disappeared. There is nothing mysterious in this extinction ; its mechanism is altogether natural (see page 413). The result will be the survivance of those most adapted to benefit the superior races. But at one time, in Australia, in Malaisia, in America, and in Europe it was not so. These very races which now are succumbing, were superior relatively to others which no longer exist. The Australians of the present, whom we look upon as savages, have a civilisation con- formable to their external condition, a certain social organisation — in relation to the Negritos of the interior of the Philippines, for example. We think we have proved that they have ejected a negro race inferior to themselves, as we now eject them. The Chap, i.] APPLICATION TO MAN. S29 wandering aborigines of Western Australia, described by Scott Wind, are the remnants of this race. In our own country, the races of the P&igord, which have disappeared before, or become absorbed into, the brachycephalic races from the East and the blondes from the JSTorth, have played the same part before the races anterior to the Neanderthal as these probably did to the Miocene races of Thenay and Saint-Prest. In these successive extinctions, which exhibit to us series of generations, strata of more and more perfect races succeeding and replacing each other, do we not recog- nise the selection by vital competition of Mr. Darwin ? But where is the character which gives the advantage in the struggle 1 Among animals, and during the first ages of the human race, the power which enabled them the better to defend themselves against other living beings, and against changes of climate and external con- ditions, was necessarily of a physical kind, such as quick-sighted- ness, more acute smell, more vigorous muscles, a constitution better adapting itself to cold or heat, to marsh miasm, or to certain kinds of diet. If Man acclimates tolerably well now, it must not be for- gotten that he owes the power, in a great measure, to the processes which he makes use of. Formerly he must have succumbed, or his constitution must have been modified. "We speak here especially of sudden acclimation. But from the period when societies were formed, and moral force took its legitimate supremacy over brute force, the advantage remained with the most skilful, the most industrious — in a word, with .the most iateUigent. Selection, from henceforth, was made to the advantage of a single organ. The largest brains — those with the richest convolutions, and with the most delicate structure, with the most appropriate histological elements — were the most favoured. Hence a state of progress which is undeniable. The process of Mr. Darwin has, therefore, had its effect in the past, as it has now in the present. With appropriate institutions we might direct it, and accelerate its already so remarkable results. The exteipal circumstances of Lamarck must, in fact, have an action of whose mechanism we know nothing. The selection of Mr. Darwin has one of which we are certain. With the latter we 2 u 630 THE PKBCURSOE OF MAN. [Chap. i. reckon hj strata of races, with the former we must do the same. The characters which we now see permanent in a given race are not the more so when we compare a succession of races. Ahsohite immohility nowhere exists; and fixity of species is only relative. May there not he other processes contrihuting to gradual transformation '! Certainly not. There are three orders of characters which transformism explains, says M. Broca, some of evolution, others of improvement, a third serial. But there is a fourth, the unimportant, the key to which he does not give. Such are the presence of the as intermedium of the carpus, the absence of a nail on the great toe, and the absence of a round ligament in the hip-joint, peculiar to the orang-outang among Anthropoids. Why, how, and when, did these characters take their origin 1 Another objection is that, in going back in the past, we do not find human races differing much from the races of the present; that we do not find, for example, men with half the cranial capacity of those of the present. But do we discover the Pliocene Man and the Miocene Man by the flint implements of Saint-Prest and Thenay ? The former made use of fire, the latter did not : is not this a reason for suspecting that the fact of the volume of his brain being less was the cause ? If he was unacquainted with fire he ought not to have the sense to bury his dead. The Anthropoids are in this condition, and we have none of their remains. Probably also, human bones do not last for so immeasurably prolonged a period. However, on surveying the road travelled over, and the discoveries made during the last fifteen years, we must not despair. Is it not by chance, when making a road or a railway cutting, or after a land-slip, or an earthquake, that discoveries of this kind arc made 1 Here a man of intellect, and one interested in the subject, should be at hand. Now, Africa, Asia, Oceania, and even the greater part of Europe, are still as it were virgin soils. Perhaps, also, the stratum in which is now lying the precurseur, not possessing language, announced by G. de Mortillet and Hovelacque is at present submerged ; perhaps he has only existed on a very limited point of the globe. Some day or other he may present himself before us under the form of a Chap. I.] THE PEECUESOE OF MAN. 531 skeleton stranded upon some tank of time, as at Grenelle; crusked under a rock, as at Langerie-Haute ; or embedded in lava, as at Denise. The derivation of Man from some previously-existing form being admitted, the question is what this form may have been, Lamarck believed it to have been a chimpanzee. We have seen that each of the three great Anthropoids approaches more or less to Man in certain characters, but not one possesses them aU. So in the inferior races ; no one race, not even the Bosjesman, is specially marked out as descending from an anthropoid — they are only made to approach more or less by such or such a character. The precursor of Man, then, is only analogous to the Anthropoids. The human type is an improvement upon the general type of their family, but not of one of their known species in particular. M. Hseckel does not express an opinion on this poiat. He asks whether the doUchocephales of Europe and Africa are not derived from the chimpanzee and the gorilla of the coasts of Guinea, both of which are dohchocephales ; and whether the brachycephales of Asia do not descend, on the contrary, from the brachycephahe orangs of Borneo and Sumatra. Many reasons lead to the belief, indeed, that all the dolichocephales are originally from Europe and Africa, and the brachycephales from Eastern Asia, not to speak of the old continent of Asia. M. Yogt thinks otherwise. He thinks that Man is only cousin-german to the anthropoid, and that the ancestor common to them both is farther off stUL Here M. Hseckel speaks positively. He says that this very remote ancestor is an ape of the old continent, a Pithecian, which was itself derived from a Lemur, and this in its turn from a Marsupial He even gives it the name of Limurien — a term borrowed from Mr. Sclater ; and, as the focus of this series of transformations, a continent now sub- merged, of which Madagascar, Ceylon, and the Sunda islands are the remains. But what becomes, in aU this, of the old dispute between mono- genists and polygenists f It no longer has any interest, and, to be brief, may be summed up as follows : As to the question of the most, elementary human types to which we might go back, types 2 M 2 i532 , GENEALOGY OF MAN. [Chap. i. utterly irreducible, wliatever their value of genera or species, in the sense usually applied to those words, are they the issue of many Anthropoid ancestors, Pithecoids or others ; or are they derived from a single stock, represented by a single individual of their genera now known, or not 1 The anthropological data given in this work appear to us more favourable to the former opinion, if we accept the transformation theory. The most characteristic races, whether living or extinct, do not form one single ascending series, such as may be compared to a ladder or a tree, but, reduced to their simplest expression, to a series of frequently parallel lines. We shall conclude by giving a resume of the possible genealogy of Man, according to Hteckel. Equally relying on comparative anatomy, palseontology, and embryology, the learned professor of zoology at the University of Jena thus gives his views on the subject of evolution : - At the commencement of what geologists call the Laurentian period of the earth, and of the fortuitous union of certain elements of carbon, oxygen, hydrogen, and nitrogen, under conditions which probably took place only at that epoch, the first albuminoid clots were formed. From them, and by spontaneous generation, the first cellules or cleavage-masses took their origin. These cellules were then subdivided and multiplied, and arranged themselves in the form of organs, and after a series of transformations, fixed by M. Hesckel at nine in number, gave origin to certain vertebrata of the genus AmjpMoxiis lanceolatus. The division into sexes was marked out, the spinal marrow and chorda dorsalis became visible. At the tenth stage, the brain and the skull made their appearance, as in the lamprey ; at the eleventh, the limbs and jaws were developed, as in the dogfish : the earth was then only at the Silurian period. At the sixteenth, the adaptation to terrestrial life ceased. At the seventeenth, which corresponds to the Jurassic phase of the history of the globe, the genealogy of Man is raised to the kangaroo among the Marsupials. At the eighteenth, he becomes a Lemurian : the Tertiarjr epoch commences. At the nineteenth, he becomes Catarrhinian, that is to say an ape with a tail, a Pithecian. At the twentieth, he becomes an Anthropoid Chap, i.] GENEALOGY OF MAK. 533. continuing so tlirotigliout the whole of the Miocene period. At the twenty-first, he is the man-ape, he does not yet possess language, nor, in consequence, the corresponding brain. Lastly, at the tioentxj-second, Man comes forth, as we now see him, at least in his inferior forms. Here the enumeration stops. M. Hajokel forgets the twenty-tliird stage, that in which the Lamarcks and ]Srewtons make their appearance. Although having attained so \oiif' an eminence, Man must have had a very low origin, in no way differing from that of the first and most simple organic cor- puscles. What he is now in the womb, he would have been, permanently on making his appearance in the animal series. This theory is painful and revolting to those who delight to surround the cradle of humanity with a brilliant aureole ; and if we were to boast of our genealogy and not of our actions, we might indeed consider ourselves humiliatea. But what is this new- restraint to our amour-propre in comparison with that which astronomy has already imposed 'i When the earth was fixed in the centre of the system, and it was thought that the universe was created for the earth, and the earth for Man, our pride ought to have been satisfied. This doctrine, called by the Germans " geocentric," as applied to the earth, and " anthropocentrio," as applied to Man, was perfectly co-ordinate ; but it fell to the ground the moment it was demonstrated that the earth is only the humble satellite of a sun which itself is but one of the luminous points in space. It was then, and not now, that Man was truly recalled to humility. It was no longer for him that the sun rose each morning, that the celestial vault was nightly bespangled with innumerable resplendent orbs. Out of all this Macrocosm there was but one lowly jjlanet left to Man. Like that peasant who dreamt that he was ruler of the world, and woke up to find himself in a simple cottage, it was not without regret that he saw himself thus degraded. Long the remembrance of his vanished dream troubled his thoughts; but he was obliged to be resigned, to become accustomed to the reality; and now h& consoles himself, as he is no longer this monarch of creation, with the thought that he is really sovereign of the earth. This undoubted royalty he has a right to be proud of. But in what way is it 534. CONCLXJSIOlir. [Chap. i. threatened or diminislied hj the transformation theory 1 Would it be less real if lie had brought it under subjugation by himself or inherited it from his first ancestors % Far from depreciating Man and his origin, the doctrine of Lamarck dignifies and ennobles them, by substituting for the theory of the supernatural the theory of the mutability and natural evolution of organic forms. But, after all, what matter to science the regret or complacency of some people % Its aims and designs are beyond their compre- hension. Man is not at liberty to put or not to put a curb upon the functional activity of his brain; his spirit of inquiry is the most noble, the most irresistible of his attributes; and as M. Gabriel de MortUlet said at the meeting of the Association for the Advance- ment of Science, his characteristic is here, and not in religiousness. For want of knowledge the imagination muses upon the unknown, and forms it to our own ideal. But to true observers the reality is sufficient; they contemplate the magnificent spectacle which is opening out before them ; they even worship nature ia its beauty, its grandeur, its harmony, and its thousand varieties of form and movement. The animal has the simple notion of cause and effect, and sees that the boundary of his faculties and senses is limited. Man alone investigates and wills ; his horizon is indefinite, like his intellectual faculties when they are exercised without trammel. Let us not, therefore, seek to contract the circle of knowledge. Is it not knowledge which has conducted us step by step, age after age, to the degree of prosperity we now enjoy % Is it not this which engenders civilisation, which adds to our well-being, brings to us the purest satisfaction, instructs us in philosophy, and secures our supremacy over everything on our planet ? Each one has his task to perform in this immense sphere. To some is given subjects of study relating to the progress of Hfe ; to others its realities. Let the former have for their object the development in society of ideas of justice, honour, and morality, without which it cannot exist. The means are within their power. Our part is to ascertain facts, to deduce from them laws, and to look at them calmly, without allowing ourselves to be carried away by our feelings. Whatever may be his origin, whatever his future destiny, Man, Chap, i.] CONOLUSIOS. 535 to the antiiropologist, is but a Mammifer, whose organisation, ■wants, and diseases are in the highest degree complex; whose hraia, with its admirable functions, have reached the highest ■development. As such, he is subject to the same laws as the rest of the animal creation; as such, he is a participator ia their destinies. THE END. I1N.DEX.

This Edition is printed on a finer paper and in a larger type than has been employed in any previous edition. The type has been cast especially for it, and the page is of a size to admit of the introduction of all the original illustrations. No such attractive issue has been made of the writings of Mr. Dickens, which, various as have been the forms of publication adapted to the demands of an ever widely-increasing popularity, have never yet been worthily presented in a, really handsome library form. The collection comprises all the minor writings it was Mr. Dickens's wish to preserve. SKETCHES BY ■' BOZ." With 40 Illustrations by George Cruikshank. PICKWICK PAPERS. 2 vols.

The Journal contains contributions by distinguished men ; short papers by prominent teachers ; leading articles ; correspondence ; answers to questions set at the May Examina- tions of the Science and Art Department ; and interesting news in connection with the scientific and artistic world. PRIZE COMPETITION. With each issue of the Journal, papers or drawings are offered for Prize Comfjetition, extending over the range of subjects of the Science and Art Department and City and Guilds of London Institute. There are thousands of Science and Art Schools and Classes in the United Kingdom, but the teachers connected with these institutions, although engaged in the advancement of identical objects, are seldom known to each other excejat through personal friendship. One object of the Journal is to enable those engaged in this common work to com- municate upon subjects of importance, with a view to an interchange of ideas, and the establishment of unity of action in the various centres. lERMS OF SUBSCRIPTION.
