OF FOOD AND DIET IN HEALTH AND DISEASE. BY GEOEGE M. BEARD, M.D. NEW YOEK: G. P. PUTIfAM & SONS. 1871. Entered according io act of Congress, in the year 1871, by GEOEGE P. PUTNAM & SONS, In the office of the librarian of Congress at Washington. PREFACE. This volume is designed to be a companion treatise to my work on Stimulants and Narcotics. What that ■work did for negative, this aims to do for positive food — to give a description and history of the principal articles of ordinary consumption ; to show their relation to each other, and their complex influence on the human system, as modified by race, climate, age, sex, ha.bit,- and the progress of civiliza- tion ; to expose the widely prevailing errors in regard tci this subject, and to point out and enforce those practical rules of dietetics which the experience of mankind has illus- trated and confirmed. The two volumes have a mutual dependence, and to a cer- tain extent supplement each other. The terms positive and negative food, which I first sug- gested a few years since, I have hei-e retained, although they have never been formally presented to the profession. The distinction whicli they imply between the respective action of ordinary food and stimulants and narcotics, though not complete or satisfactory, is yet convenient and clear, and in the present state of our ignorance of the subject, is per- haps about as far as we can go. Strictly speaking, we do not, in the last analysis, know how food of any kind sustains the system. Why it is and how it is that beef and bread, iv PKEFAOE. fruits and vegetables, when digested and taken into the cir- culation, supply heat and force and the material for growth and repair, we do not precisely know ; and all the labors of chemists and physiologists leave us still in the dark. To those who have derived their conceptions of dietetics from the noisy and ignorant charlatans who in this country more than in any other, through the unfortunateindiffer- ence of the profession, have monopolized the public atten- tion, the facts and conclusions of this work must seem revo- lutionary, if not incredible. Those who believe that the chief end of man is to be hungry, will find in this volume little to confirm, perhaps much to disturb that belief. Those who expect that the na- tural a^jpetite, as a guide in determining the quantity and qual- ity of our food, is to be superseded by the chemist or the scales, and who are unwilling to listen to opposing argu- ments, will need to read no further than this preface. The vast avmy of Jeremiahs who have gone up and down the land, predicting that our gluttony would be our ruin, will be surprised and gratified at the suggestion that the vice o| over-eating, once so prevalent, is under civilization fast disappearing, and that it is no longer national or univer- I sal ; that indeed the tendency among the intellectual and cultivated classes of our time is to eat too little rather than i^^o much. If there be any who suspect that the classification of Lie- big has correctly or exhaustively expressed the chemistry of food, they would do well to consider the very numerous facts which demonstrate that iu extremely hot, as well as in extremely cold climates, the so-called heat-producing foods in large quantities are imperatively demanded. The dogma that fish diet increases the power and activity of the intellect — which, unlike most of the popular errors, has been sanctioned by eminent names in science — which has hitherto never been formally disputed, I hiJve shown to be quite the reverse of the truth, and if there are any -yho have failed to derive the promised increase of brain-power PEErAOE. V \ from a diet composed largely of fish, they -will find in this ■work the consolation that they are not alone in their failure. The cruel edicts which dietarians have so rigidly enforced —that only one or two varieties should be taken at a time ; that there should, be no drinking at meals ; that the appetite is to be subdued rather than guided, and that a sense of sa- tiety^is a_ j!onviction of sin — are shown to have no scien- tific foundation. For- those who are proclaiming that the hope of salvation of the race depends on our returning to the dietetic habits of our fathers, I have adduced facts and reasonings, which show that the law of evolution applies to diet as demonstrably as to all else in (nature, and that to re- vive the eating and drinking customy of the past, while re- taining our present customs and constitutions, would be to imperil our civilization. The dietetic treatment which I have recommended for nervous dyspepsia— a disease with which nearly all intelli- gent Americans become acquainted before they die — will be found to be as much more successful than the opposite me- thod, which has so long prevailed, as it is m.ore scientific and agreeable. The task which I have here begun of raising hygiene to a science, based on experience, and confirmed, guided and illustrated by chemistry, physiology, and other allied sciences, is one of appalling difftculties, not the least of which is, that first of all it becomes necessary to clear away the rubbish that has been accumulating through centuries of ignorance, and to eradicate errors that have been so long rooted in the popular mind, as to have acquired the strength that belongs to possession, and the authority and sacredness that are attributed to age. Fully recognizing on the part of a popular scientific writer a double fealty, fin the one hand to the science that I represent, and on the other to the people for whom I write, I have sought to make these works as true to scientific methods as though they were designed for VI PEEFACE. an audience strictly professional, and at the same time fully comprehensible to the readers of the ordinary newspaper, which in this country constitutes the almost exclusive intel- lectual entertainment of those who are able to read at all. It has been my aim to treat the subjects here discussed so thoroughly and so impartially, that even those who question the soundness of my views, may find in these volumes the best materials to sustain their gueries, and the strongest weapons with which to combat the doctrines that I teach. Some of the practical portions of this work — the diet of brain-workers and students — originally appeared in the Hours at Home magazine, and the College CouranI, and it has been a source of gratification to learn that they have been of substantial service to many erring sufierers. My hope is that in this permament form they may be yet more widely useful. I desire to express my obligations to Mr. S. B. Noyes, Librarian of the Brooklyn Mercantile Library, who, during all the laborious investigations that the preparation of these works have called forth, has very cheerfully and with remark- able patience, and oftentimes without solicitation, given me the aid of his extensive bibliographical knowledge and ex- perience, and the free range of the remarkably well-selected collection of books under his charge. Similarly, I am indebted to Mr. Hannah, the accompUshed Librarian of the Long Island Historical Society. For information concerning the dietetic habits of the East, I am under obligations to Naotaro Yangimoto, of Japan. o. M. B. New Yoke, October 1st, 1871. SOUECES OF INFOEMATION ON THE SUBJECT OP THIS WOEK. Until quite recently, the profession had written scarcely any- thing of truly real value on the important department of Dietetics. - Within the past few years a number of careful and scholarly ob- servers, especially in Europe, have endeavored to advance and to popularize this branch of hygiene both by laborious experiment- ing and a judicious use of the pen. Of the very numerous special writings on this subject that have recently been pubhshed in this eountrj', none, so fer as I am aware, have been prepared by writers of scientific attainments and reputation ; and most of them contain such a large admixture of er- ror and absurdity that they should be carefully avoided by those who have any regard for scientific truth or for their own physical wellbeing. The latest views of the profession on the subject are found in the following wiitings, to many of which I have been more or less indebted. H. Lethebt. — ^Lectures ctu Food, London, 1870. C. A.

The object of eating and drinking is to impart heat and force to the system, and to supply its waste. All ac- tivity of the body — of the nervous as well as of the muscular system — is attended with waste. We cannot run, nor hop, nor skip, nor sUde, nor bend, nor fall, nor breathe, nor hold our breath, nor lift a finger, nor hold a finger stUl, nor wink, nor weep, nor smile, nor attempt to repress our emotions ; nor open or compress the lips, nor take a swallow of food or drink, with- out changing or consuming some portions of the body. All mental activity is as much the result of bodily change as muscular. For the reasoning of the philoso- pher and for the love of the maiden ; for the calm cal- culation of the scientist and the wild frenzy of the poet ; for all fear, for all hope, for all fancy, for all adoration, there is a corresponding change and waste of the brain. It is believed that for every time we break forth into passion, or breathe a prayer, there is waste of cerebral 2 EATING AND DRINKING. tissues without which such prayer or passion would have been impossible. In the great economy of nature force answers to force and everything must be paid for. ■ Just as the candle grows shorter as it gives light; just as the coal on the grate is consumed while it warms the room ; just as in the galvanic battery the acid eats away the zinc in exact proportion to the quantity of elec- tricity evolved, just so the brain wastes with every thought and motion.* The writing of this work, of this paragraph, of this very sentence, costs more or less cerebral substance, which if not replaced will leave the author poorer than when he began it. The brain of the reader wastes as he turns over these pages ; if he accepts these views, waste will attend the emotion of acceptance ; if he re- jects them, the feeling which induces such rejection will be attended by chemical changes in the brain, and ad- ditional argument will be arrayed against him. If he merely doubt these views, the act of doubting will cost him something of the most valuable part of his body, by a process that ought to aid in setthng his doubts. THE WASTE OP THE SYSTEM DURING LIFE NEVER CEASES. Even in sleep these vast and complex changes do not cease. In the great human laboratory, the sound of the saw and the hammer is always heard by night as well * The question of materialism we have here no space to discuss. The state- ments made above rightly represent the views of the most advanced cerebro- physiologisits, and are admitted alike by those who favor and those who oppose materialism. THE WASTE OP THE BODY SUPPLIED BY FOOD. 3 as by day, and only stops when its doors are closed for ever. "Whether the sleep be profound or broken the great tide of life rolls continuously, and every breath ■we draw is the signal for innumerable atoms to change their places. That unknown and unknowable force which we call Life, is a great commander, and he controls a mighty and complex army. When he wills, the nerves of vital force, travelling at the rate of 100 feet per second, carry his commands from the head-quarters in the brain to any one or to every organ; files of atoms range in platoons, form in line, right about face, deploy to the right and left, march slow or double quick, and an army which no man can number marches hither and thither, keep- ing time to the rhythm of the heart. In short, the changes of the body are greatly dimin- ished in activity, hence the necessity of sleep ; but they do not entirely cease. The machinery is still going, but more slowly, and at less expenditure of force. THE WASTE OP THE BODY MUST BE SUPPLIED. Both the matter and the force of the body are limited. Great is the difference between the. weakest and the strongest spesiraens of humanity ; but the strongest are after all but weak, and both extremes and all the intermediate grades are alike dependent on the supply of matter and force that comes from food. Just as one who continually draws on a limited ac- count without making a deposit, must in time become poor ; just as the candle burns to the socket, and the lamp gives out because there is no more oil in it ; just as the Jire on the hearth, unfed by fuel, grows fainter and fainter and goes out in darkness ; just as in the gal- 4 EATING AND DEINKING. vanic battery the zinc must in time become so far con- sumed and corroded that it can no longer generate an electric current, just so the body, if its ceaseless wasting be not supplied, must grow weaker and smaller, and in a few days must die. It has been estimated that the body can be reduced two fifths of its weight before starvation ; that up to that point the body can feed on itself, on the reserve of nutriment stored up in its own receptacles. As an av- erage estimate, this is probably not far from correct ; but undoubtedly the starvation point must widely vary with the race, the climate, the state of health, the tem- perament and the power t)f will. MATERIAL NECESSARY FOR THE GROWTH OE THE BODY. Prom birth up to the age of twenty-five or thirty, or even later, the body with greater or less rapidity and constancy increases in size and weight. Between thii-ty and fifty, and even later, even to extreme old age, there may be increase of adipose tissue, though the stature ,is usually fully attained before that period. There is Httle doubt, also, that the brain may increase in size after as well as fore thirty, and that this increase may go on, at least till middle life is reached. Now in order to carry on this growth there is as much need of material as there is to evolve the forces of thought and motion ; and if the material be wanting, or if it be meagre and insufficient, the growth must either cease or be retarded. Just as a plant deprived of its needful soil, moisture and sunHght, becomes stunted and dwarfed, so the body, deprived of necessary food, becomes weak and sickly. DIFFICULTY OF DEFINING FOOD. MATERIAL NECESSARY FOE "WAEMTH. The heat of the body is maintained by the chemical changes that are constantly going on in it, and which are necessary for its existence and growth. Animal heat is a resultant of all or of many of these various changes and transformations, that never cease in the body so long as life remains. If, therefore, material must be suppUed to replace what is lost in substance and in force, it must also be supplied to keep up the warmth that is generated by the active metamorphosis of tissues. Without sustenance the body becomes cold, and the greater the amount of cold that the body suffers, the greater the amount of sustenance that it requires. HOW THE FOEOES, THE GEOWTH, AND THE HEAT OF THE BODY AEE MAINTAINED. The forces, the growth, and heat of the body are prin- cipally maintained by eating, drinking, and breathing. The air we breathe supplies the system with oxygen ; the water we drink siipplies oxygen, hydrogen, and va- rious mineral S9|lts ; the food we eat supplies nearly aU of the fourteen elementary substances of which the body is composed. Ordinary food also contains more or less water, is indeed largely composed of water ; and of many alimentary substances, it is the principal in- gredient. DIFFICULTY OF DEFININGt FOOD. The terms- that are most used, most familiar and for aU practical purposes best understood, are oftentimes the most difficult to define. Food is a word over which 6 EATING AND DEINKING. there has been not a Utile dispute, and concerning its true and exhaustive definition there are broad differ- ences of opinion. In the widest sense, it may include all, however taken into the system, that supplies its waste, maintains warmth and growth, and which corrects, inten- sifies, or economizes the vital forces. Thus defined, it includes the air that we breathe, the solids that we eat, the liquids that we drink or absorb, as well as the active principles of most of the stimulants and narcotics, which are negative food.* Strictly speaking, all medicine is food, and all medi- cal treatment, even external applications, act as food, either in a positive or negative sense. We might go even further, and include under the term all those nameless hygienic and mental influences that serve to supply the waste of the body or intensify or economize its forces. Certainly it is in no way fanciful to call sunlight food, for it is indispensable to health ; and good news from a far country is often as truly food as water to the thirsty or as meat to the hungry. The difficulty of accurately defining food comes from our ignorance of physiological chemistry. We know so little of the hidden processes of this body of ours, that we cannot well define what does and what does not minister to its substance. For aU practical purposes food may be used in its popular sense to include those substances, whether liquid or solid, which, when passed into the system through the or- gans of digestion, sustain life. Food, as thus defined, I have divided into two classes — Positive and Negative Food. Positive food includes the ordinary articles of diet. * See my work on Stimulants and Narcoiics.'ot this s HUNGER— THIBST — STAEVATION. 7 both fluid and solid, that supply positive nutritive mate- rial to the system. Negative food includes those substances that are em- braced under stimulants and narcotics. y?he subject of stimulants and narcotics is one of such great difficulty and importance that it has been thought worthy of separate and special consideration. HUNGEE— THIRST— STAEVATION. Hunger is the prayer of the body for nourishment. Hunger may be appeased either by sohd or liquid food ; thirst is satisfied only by water, either alone or in com- bination with solids or other liquids. This prayer of the body for nourishment should not ordinarily go long unanswered. If either positive or negative food is not speedily forthcoming after the de- sire begins to be intensely felt, the system suffers. One of the most terrible of deaths is that of starva- tion.- But although the sufferings of the starving are very great, it is not so much hunger as debility and pain of various kinds that causes the suffering. I was told by a medical friend, who for two days was lost in the woods without anything to eat, that the sensation of hunger soon j>assed away, and an attack of nausea and vomiting, re- sembling sea-sickness, came on that compelled him to rest for several hours. This attack was followed by painful debility but not by hunger. Starvation from want of water, must be a death even more terrible than that fi-om want of solid food, for thirst is a tyrant vastly more imperious and exacting than hunger. A fearful picture is drawn by Vambery 8 EATING AND DEINKINGt. of the agonies he bore in the Persian desert, from want of water. A few days at most is as long as we can exist without some form of liquid or solid, positive or negative food.* .^ The stories that periodically arise of young girls whbs, live for weeks and months without food, may probably be explained partly by fraud, and partly by ignorance. At aU events they do not, thus far, seem to bear rigid scrutiny. — — . -^ * In my work on Stimulants and Narcotics, I hare given a number of re- markable illufitrations of the sustaining power of alcoholic liquors, coca, coffee, etc. CHAPTEE IL HOW MEN HAVE FOCND OUT WHAT TO EAT AND DRINK — CLASSIFICATION OF FOOD. Whethee we accept or reject the Darwinian theory of development, we must, at least, concede that the present civihzed races of the world have arisen by slow advances from the condition of semi or absolute savagery. In order to answer the question how man has found out what to eat and drink, we may well go back to the early struggles for existence, before civilization, as we now un- derstand the term, had ever been begun. We may sup- pose, for example, that a portion of a tribe of about the condition of the native Australians, had been mirac- ulously sustained by manna up to early manhood, and had been then let loose, we may say, on the African continent. In a few hours they would be hungry, and would seek for something to eat. They would be thirsty and would seek for something to drink. How would they find out what would be good and what bad, what palatable, and what nauseous? There would be no physiological chemistry to tell them, no one to analyze the berries, herbs, roots, barks, leaves, around them, and determine which were best designed for the human system. 10 EATING AND DRINKING. Obviously there would be but one way of answering the question : that is, by trial of whatever they could Jind. In setthng the question of the healthfulness of any substance, the taste would be usually a reliable guide, since few natural substances that are grateful to the palate are injurious to the system. But in order to learn the taste of any substance they must iirst try it, for neither the sense of vision nor the sense of smelling could be depended on. The taste even could not be relied on entirely, for many substances that are more or less disagreeable, may yet be valuable as food, and may, in time, become delightful. The same difficulties would be encountered in the selection of animal food. Not until they had eaten the animal, or a part of it, cooked or uncooked, could they know what was good and what was evil. For drink they would naturally experiment first of aU with the water of the springs, lakes, and the ocean, and not until after trial would they know the difiference between salt water and fresh, or hard water and soft. They would be just as likely to lie down on the beach and lap the waves of the sea, as by the brink of a moss fringed stream. Their next experiment would likely be with the milk of animals or of trees, and with the juicy fruits. As with vegetables and drinks, so with fruits ; the good would be discerned from the bad, only by trial, for neither the eye nor the smell would properly distinguish. The observations of each individual would be com- municated to the other members of the tribe, and their accumulated dietetic knowledge would be handed down from generation to generation. EAELY EXPEBIMENTS OF MAN. 11 As a result of this method of experimenting, it must necessarily follow — 1. That many must suffer in health, and lose their Uves, by taking improper nourishment. It is probable that many thousands have thus died that we might live. When we consider that, even in our time, the accumu- lated wisdom of the ages does not prevent the occasional poisoning of a family by mushrooms, or by ill selected oysters, or lobsters, eaten out of seasoQ, or not properly cooked ; that meat, by parasites or otherwise, annually slays its victims ; that unripe and harmful fruits every season increase the rate of mortality ; and that many of these pernicious substances are eaten entirely with- out suspicion of their pernicious character, from their taste, or appearance, or flavor, we see that the reasons are strong enough for believing that our distant ances- tors must have suffered more than can ever be estimated in their long struggle for existence, from want of die- tetic knowledge. At first every mouthful was an exper- iment, and an experiment that might end in disease or death. 2. It would follow that the diet of the world would be modified by race, climate, soil, and the state of sav- agery or civilization. The past and present history of the world shows that such is the case. The dietetic customs of the world are as opposite as their religious, or political, or social customs ; and among all nations of a progressive character there has been change in dietetic habit, with the change in civilization. " Half the world," it is said", " know not how the other half lives.'' The diverse customs of the world in eat- 12 EATING AND DEINKINQ. ing and drinking will be described in a subsequent chapter. As the object of food is to supply the waste of the body, it is obvious that the constituents of food must, to a certain extent, correspond to the constituents of the body, although the body is a laboratory whose subtle chemistry may and does variously transform the dissim- ilar substances that it receives. ELEMENTAHY CONSTITUENTS OP THE HUMAN BODY. The number of elements of which the world is com- posed is sixty-two. The number of elements in the human body is four- teen, as follows : Oxygen, Calcium, Iron, Hydrogen, Sulphur, Potassium, Nitrogen, Fluorine, Magnesium, Carbon, Sodium, SUieon. Phosphorus, Chlorine, The urgency, and frequency with which any element or proximate principle is required by the body, is to a certain extent proportioned to its relative importance. Oxygen, for example, is found in the body in great abundance, for it is one of the elements of water ; and w^e cannot live without breathing. Thirst is more imperative than hunger ; we drink far oftener than we eat, and water is the principal constitu- ent in all our food. Phosphorus is one of. the most important and variously combined of all the elements; hence its eminent importance in food and in medicine. CONSTITUENTS OF FOOD. 13 The elements of the human body are combined into the following PKOXIMA.TE CONSTITUENTS. Water, wHoh constitutes about Pbosphate of Potash, two thirds of the weight of the •' "Magnesia, body. Carbonate of Lime, Albumen, " " Soda, Fibrin, Chloride of Sodium (common Fat, , salt), Gelatine, Sulphate of Po'ash, Fluoride of Calcium, Protoxide of Iron, Phosphate of Lime, Sulphate of Soda, " " Soda, Silica. These elements and proximate principles must be supplied to the system directly or indirectly by the air we breathe, and the positive or negative nutriment that we take. DIVISIONS AND PBOXIMATE CONSTITUENTS OF FOOD. The common varieties of food may be arranged un- der the following general divisions : I. — Caebo-Hydeates. Alimentary substances that are composed of carbon united with hydrogen and oxygen, are called carbo-hy- drates. The proportion of hydrogen and oxygen is the same as that in which thoy exist in water. Under this head are included the following : 1. Starch. This is the most abundant material for nutrition that is known. It consists of grains that vary in size from ^^ to ^^^-j- of an inch in diameter. Starch constitutes about 5 per cent, of turnips, 15 14 EATING AND DEnjKING. per cent, of the potato ; 60 per cent, of wheat, 82 per cent, of rice. It is found also in arrow-root and tap- ioca. 2. TSugars. Of sugars there are nearly a dozen differ- ent varieties. Among them are Saccharose or cane, found in sugar cane, beets, maple, carrots, pumpkins, etc.; Glucose or grape sugar, found in honey, figs, grapes and other fruits, and Lceuulose ov fruit, found in certain fruits, honey, and molasses. This latter does not crystallize. Fectose. The.pectose bodies are found in vegetables, in fruit, in roots, and in foliage. It is called vegetable jelly, and somewhat resembles starch and sugar. Inulin. This substance is much like starch, and is found in several vegetables, as the dandelion and chicory. Dextrin. This is found in very small quantities in several plants. In the process of malting corn it is pro- duced from the starch. Vegetable Acids. These are composed of carbon,hydro- gen, and oxygen. Those which are principally known are acetic acid, produced from fermentation) of the juice of plants ; malic acid, found in apples, plums, cherries, and other fruits, and in rhubarb ; tartaric acid, found in the grape, and pine and apple, etc. ; citric acid, found in the lemon ; and oxalic acid, found in the rhubarb, sorrel, and other plants. II. — Oils and Fats. Carbon, hydrogen, and oxygen, make up oils and fats, but in a different proportion from the carbo-hydrates. The principal fats are — Slearifi, found in tallow. Olein, found in oils. Pahnitin, found in butter, wax, and oils. ALBUMINOIDS — SALTS. 15 All these consist of fatty acids combined with gly- cerine. Of the elements that are necessary for nutrition, the fats and carbo-hydrates supply only three ; it is sup- posed that they cannot make flesh. m. — Albuminoids. The leading albuminoids are — Albumen, found in plants and animal substances. Mbrin, found in vegetables and animal substances. Casein, found in the pea, the bean, and in animal substances. The gluten of wheat flour is composed both of fibrin and albumen. There are also other albuminoids that closely resemble each other. The albuminoids contain nitrogen, sulphur, and phos- phorus. They are called Jiesh-formers IV.— Saits. Under this division are included Potash, Soda, Lime, Magnesium, Iron, etc. These saline matters are found associa,ted with the albuminoids. Common salt comes under this division. "Water also contains salts of various kinds. CHAPTER III. HISTORY AND DESCRIPTION OV THE PRINCIPAL VARIETIES OF FOOD. In this chapter I purpose to give a very general de- scription and history of the varieties of food that are most familiar to my readers, making no endeavor to be exhaustive. ANIMAL FOOD. Animal food serves an important and indispensable part in human nutrition. Life can be maintained with- out it, especially in temperate climates ; but the highest activity of the braiu and muscle is only pos- sible for those whose diet consists in part of animal food. That man was designed to eat animal food, is shown : 1. By exjaerience, and 2. Is confirmed by a study of his organs of nutrition. The size, shape, position of the teeth, and the length of the alimentary canal, show as clearly as any fact ia comparative anatomy can be made, that man does not deceive himself when he concludes from his experience that he is 'better, and stronger on a mixed than on a purely vegetable diet. ANIMAL FOOD. 17 Beef. — Of the different kinds of meat in common use, beef unquestionably stands at the head. It is the king of the meats. It is about three fourths water and one fourth solid matter. Fat is more nutritious than ' lean meat, but is more difficult of digestion, and there are very few in our climate who can take it in large quantities. The solid portion of beef is composed of albumen, fat, creatin, creatinin, inosinic acid, muscular tissue, and various salts. Mutton differs but little from beef in its composition, and is next the throne. The English mutton is far superior to the American, and in England mutton is more used than with us. The pecuUar taste of mutton makes it less popular than beef. Bacon and Poke. — The bacon of England and Ireland is superior to that of America, but it is nowhere the best kind of meat. It contains so much fat that only the hardy can digest it in large quantities. In the cities of this country it is but little used by those who are able to get anything better. Pork, fresh or salted, is an article of diet that ought to disappear, and is disappearing before civilization. For centuries it constituted the leading article in the dietary of Europe, but with the advance of culture and the improvement in the race, the desire for it, and the ability to digest it, are both diminished. So thoroughly unfadiionable is even fresh pork in our large cities, that a hotel or boarding house that should provide dinner in which pork should be the only meat, would soon be empty ; and fried salted pork is reserved for the ex- tremely poor. In country places, among the farmiug 18 EATING AND DEINKING. population, where the desire for this kind of meat and the ability to digest it have not yet disappeared, and ■where other meats are scarce or inaccessible, fried and boiled salt pork is still the great dependence. Poultry, Babbits, etc. — The flesh of poultry, rabbits, hares, is less nutritious than beef or mutton, but aflbrds a pleasing variety. Wild fowl and game of all kinds are inferior to beef and mutton, and some varieties are difficult of diges- tion. Veal and Lamb. — Veal speaks for itself to those who have been forced to subsist on it. Why it is that young beef, which is so tender, is yet so often the cause of di- gestive disturbance, has never been explained. Lamb is much more healthful, and is more palatable. Horse Flesh. — The use of horse flesh as an article of diet is by no means a new experiment. It is said that during the French Eevolution the populace were fed for six months on the flesh of horses, and no injuries re- sulted, although severe complaints were raised against it. Baron Larrey states that during his compaigns, he gave horse flesh not only to the soldiers, but to the sick and convalescent in the hospitals. In 1835, in Paris, a commission of distinguished men was appointed to determine whether horse flesh was good food. They decided that it was palatable, and that they "could not detect any sensible difference between it and beef." In 1841 horse flesh was openly sold at Wurtemberg, and since that time it has increased in popularity and is sold both in Paris and in Germanv, ANIMAL FOOD. 19 Since that time, also, very many experiments have been made by the giving of banquets to settle the qiiestion of the palatability and the digestibility of horse flesh. The pretty unanimous result of the experiments is that it is sometimes quite difficult to distinguish roast horse from roast beef ; that the horse soup was preferable to beef soup. More recently stiU it has been proposed to popularize horse flesh as a measure of economy, and in order to help out the bad nutrition of the poorer classes, econ- omy being regarded as its chief recommendation. Bones contain considerable fat and nitrogenous mat- ter. It has been estimated that 6 pounds of bones boiled for one hour, are equal to one pound of meat in nitrogen, and to nearly two pounds in carbon. Teipe contains 13 per cent, of albumen, and 16 per cent, of fat. It is easy of digestion, but a poor de- pendence for a meal. Blood. — ^Pig blood is sometimes mixed with groats and fat, and the mixture is called black pudding. Eggs. — There is in eggs about 25 per cent, of solid matter ; of this 14 per cent, is nitrogenous, and 10^ per cent, is carbonaceous. The yolk has 31 per cent, of fat. The white is mostly albumen. Eggs are deficient in carbon. Here they are com- bined with bacon.' Milk.— MUk is the food that is designed for the young 20 EATING AND DRINKING. of. mammals ; but its value for adults has been gi'eatly overrated. Milk is composed of water, butter, sugar, casein, and mineral substances. The relative pro- portions of the different substances vary in the dif- ferent kinds of milk, but in no kind does the solid mat- ter exceed 182 parts out of a thousand. In the milk of woman the proportion of solids is 110.92 parts out of a thousand. Cbeam, which appears in the form of globules that gradually rise to the surface, contains about 35 per cent, of sohd matter, and about two thirds butter. Whey contains the sugar and saline matter. In but- termilk all the fat is excluded. Butter consists of fatty and oily substances, saline matter, water, and casein. The proportion of fat is from 70 to 95 per cent. Cheese is the casein of milk coagulated by rennet or by some acid. The sugar of milk does not ferment like other sugars, else milk would be unfit for infants. The milk of the ass, and the cow, and the sow, contains more sugar than that of woman. Goats' milk contains more butter but less sugar than that of woman. THE COW TREE. Corresponding to the bread fruit, there are in certain warm countries milk producing plants which are found in a certain district of South America. The milky juices of plants are generally acrid, bitter and injurious as food ; but that of the cow tree, which is obtained by FISH. 21 making incisions in the trunk, is described by Hum- boldt as " tolerably thick, devoid of all acridity, and of an agreeable balmy smell." Humboldt further says that " amidst the great num- ber of curious phenomena tvhich I have observed in the course of my travels, I confess there are few that have made' so powerful an impression on me as the aspect of the cov? tree." The same authority further states, that " this cow tree, like ordinary cows, is milked in the morning ; for then the fluid is most abundant." ■ Then " the negroes and natives are seen hastening from all quarters, furnished with large bowls to receive the milk, which grows yel- low and thickens at its surface." Caoutchouc, or rubber, is a kind of vegetable mUk, since it contains caseous matter. VEGETABLE CHEESE. When the milk of the cow tree is exposed to the air, the yellow cream rises to the top, and a substance is formed resembling cheese, and is so called by the natives. BDTTEE TKEE. Mungo Park speaks of a tree in Bambarra that gave an oily substance resembling butter ; and the same is mentioned by more recent travellers. FISH. Among the white varieties of fish are whiting, cod, haddock, sole, flounder. These contain only about 22 per cent, of solid matter, and of this 18 per cent, is nitrogenous. 22 EATING AND DKINKING. Mackerel, Eels, Salmon and Hereing. — These cbntain much more fat. All fish are best at the time when the roe ripens. At this time they are fatter, richer, and have a better flavor. Shell Fish. — Shell fish contain about 13 per cent, of solid matter. Oysters are the easiest of digestion. Lobsters, crabs, scollops, mussels, etc., are more difficult to manage, especially when not weU cooked, and the latter some- times cause serious injury. Turtle.- — The flesh of the turtle contains much less fat than is supposed. It is about three fourths water, and fat constitutes only about ^ per cent, of • its sohd ingredients. Genuine turtle soup is more digestible than the so- called mock turtle. CEEEALS. Wheat, Eye, Barley and Oats. — ^The early history of Jihese cereals is not fully known. It is stated that the habitants of the lake dwellings of Switzerland culti- vated the cereal plants. But as Darwin remarks, " bot- anms are not universally agreed on the aborigiaal par^tage of any one cereal plant." It is stated that all our celseal plants are cultivated varieties of wild species that havte been found in Asia. There Is little question that man very early began to cultivat^the earth, and that from a very distant period these cereals were used by him as food. Of all the cereals wheai is the most used. ^y THE CEREALS — BEEAD. 23 Oatmeal does not make bread. Oatmeal porridge is, however, a leading article of food with the peasantry of Scotland, Ireland and England, and was formerly used by the wealthy and luxurious. Barley fiow, unless mingled with wheat flour, does not make good bread, and, therefore it is chiefly used in the form of porridge. Bye flour is inferior to wheat flour, but it is much used in connection with it. Rye bread is common in Germany, and in the United States is used not a Uttle, alone, or mingled with Indian meal or wheat flour. BREAD. Bread is made of several varieties of cereals ; but wheat bread is the form that is most used. The wheat is ground and sifted. Wheat contains from 60 to 90 parts of flour, to from 10 to 40 parts of bran. The average is about 10 per cent, of bran. There are several gi'ades of flour. The first is fine flour, and contains no bran ; the second, called canaille or seconds, contains a little bran ; the third, called shorts, contains a larger percentage of bran ; th.& fourth, called pollards, is almost all bran, and is usei mostly for animals. Unbolted wheat flour makes, what is called in Europe, " brown bread," and in America " Graham bread," after Mr. Graham, the founder of " Grahamism." It is less di- gestible than bread made of fine flour, but it contains some important nutritious ingredients in the bran, and is more laxative than the bolted. Bread contains about 60 per cent, of solid substances, 55 to 58 per cent, of dextrin, gum, stafch and sugar, 1^ 24 EATING AND DEINKING. per cent, of fat, and 8 to 10 per cent, of nitrogenous substances, of which starch is the leading ingredient, and 40 per cent, of water. The proportion of water varies with the age of the bread, and the method of making. Maize ok Indian Cobn. — ^Indian corn is without doubt of American origin. It was used by the aborigines in both North and South America, and two kinds of it have been found in the tombs, " apparently prior to the dynasty of the Incas." Very numerous varieties have arisen. Indian meal is made into a bread that is called "brown bread," or " corn bread ;" it is a favorite in New England and in the Southern United States. In New York and the Middle States it is but little used, and is there known as the "Boston brown bread." It is healthful, nutritious, contains a good proportion of fat. It is more laxative than wheaten bread, but is less adapted for feeble digestion. Buckwheat Floub in the form of "buckwheat cakes" is distinctively an American luxury. They do not con- tain all the elements of nutrition, but usually, when properly made, are easy of digestion, and as beneficial as they are delightful. Their deficiencies are generally made up by the molasses, or sugar, or butter, or cream, or milk, or gravy, or meats with which they are eaten. EiCE is in some features nutritious ; yet it is not the best food, although millions subsist on it. It is deficient in important elements of nutrition. It is better adapted for warm than cold climates. In cold and temperate regions, and for hard workers with brain and muscle VEGETABLES. 25 in. any climate, it does not sufficiently exercise tlie stomach, nor warm the system, nor feed the brain o^ muscle. VEGETABLES. Potatoes. — The potato is an American plant. The cul- tivated varieties differ but little from the wild species. It is stated that in Great Britain 125 kinds of potato exist. The potato contains about 25 per cent, of solid mat- ters, four fifths of which are carbo-hydrates, and the remaining fifth fats, albuminoids and salts. The potato alone, therefore, can sustain life, but it is very deficient in fat and in the phosphates. It is the king of the vegetables, but as an exclusive diet it is to be deprecated. Sweet Potatoes. — This vegetable, which is much used in the South and the West Indies, is hardly as digestible for the majority as the so-caUed Irish potato. It is, however, very palatable, and need not be feared by those to whom it has not in some way shown itself inimical. Yams. — The yam, so much eaten in the West Indies, resembles the sweet potato. It is quite nutritive. When ground into flour it is made into bread. In the same way ordinary potatoes are in America sometimes min- gled with Indian meal to make brown bread. Plantains .^The plantaia, though a fruit, is to the tropics what the potato i? to the temperate regions. In large districts of Africa, it is a great dependence, and wines or beers are also made from it. TuKNiPs, Pabsnips and Caeeots. — These vegetables 26 EATING AND DRINKING. •contain a larger percentage of water than the potato, and are of much less value. They are quite palatable, and help out the variety in a dinner. Cabbage.— The cabbage is believed by many to be descended from a wild plant that grows on the western shores of Europe, while others contend that its ancestors are to be found on the Mediterranean. The cabbage contains only about 5 per cent, of solid matter. Like all other vegetables its value in diet con- sists of its saline ingredients. Peas and Beans. — A kind of pea now extinct has been found in the lake dwellings of Switzerland. The common garden pea is believed to be descended from a variety that has been found in the Crimea. Peas and beans are valuable for their legumin, which resembles casein of milk, and which constitutes nearly one fourth of their weight. Their nutritive value has been much overrated. Beets. — Beets contain a considerable percentage of sugar, and are, therefore, nutritive, but they are only of value in connection with other food. Onions. — Onions contain nourishment, and in the opinion of some are superior to any other vegetable. Raw onions are usually disagreeable to a dehcate stomach. Leek, garlic and shallot are very similar to the onion. All of these vegetables are more used by sailors than by landsmen, and in the West Indies, and in warm chmes generally, than in the North. J FRUITS. 27 CuouMBEBS. — Cucumbers, whether eaten fresh or in the form of pickles, are of but little value, except to give variety and to stimulate the appetite. To some temper- aments they are indigestible and must be used sparingly or wholly abstained from. Those who taste them over and over again after they have eaten, may as well do without them — and they can do so with the consolation that they are losing but little. Pumpkins and Squashes. — These when made into stews contain a small amount of nutriment, are quite palata- ble, and are rarely otherwise than a beneficial accom- paniment to more substantial food. Tomatoes. — Tomatoes were formerly regarded as only fit for hogs, and their introduction to fashionable tables in this country in raw and stewed form is of very recent date. Their value as medicinal food has probably been much overestimated, and is based chiefly, I think, on the same theory that has given Graham bread such great promi- nence, namely, that the value of any article of food is in pretty exact proportion to its disagreeableness, since, to the majority of persons,, tomatoes are at first repulsive. There is no evidence that they are in any respect su- perior to ripe peaches, or pears, or apples. Tomatoes are said to contain considerable oxalic acid. FEUITS. The Peach. — The peach is a native of Persia. Orig- inally it was a kind of bitter ahnond, but by long cul- ture has developed into the luscious fruit as it is now known. Itwas carried into Italy by the Romans, and 28 EATING AND DKINKING. thence into France. It was introduced into England about the middle of the 16th century. At first it was thought to be injurious on account of the prussic acid contained in it. There are 20 known varieties of the peach, and 20 varieties of the nectarine, which closely resembles it. The peach is one of the most healthful as well as the most agreeable of fruits. It can be eaten in enormous quantities without injury, and oftentimes with positive benefit. Apricots. — The tree on which apricots grow is de- scended from a species that is found wild in the Cauca- sian region. It is estimated that there are 12 varieties. PLtfMs. — The plum tree is supposed to be descended from the huUace, which is found wild in the Caucasian region, and .in Northwestern India. There are about 40 varieties. Cheekies. — Cherries are believed to be descended from several wild stocks. Apples. — ^Whether the apple is descended fi'om one or from several closely allied wild forms, is a matter ol doubt. There are now nearly 1,000 varieties. Peaks. — ^Pears a.-e descended from one form that ia found wild. Both pears and apples, when ripe, can be liberally used without fear by the majority of those in average health. There is need, however, of greater caution than in the use of peaches. FRUITS. 29 Stbawberbies. — ^In 1246 only three varieties of the strawberry were known. "At the present day the varieties of the several species ai'e almost innumerable," and they have greatly increased during tte past half century. "With culture it has wonderfully increased in size and quality. Gooseberries. — The gooseberry plant comes from ar wild form that is found in Central and Northern Europe. There are now about 300 varieties. Under cultivation it has greatly increased in weight. The present weight has been known to be seven or eight times the weight of the wild gooseberry. Watermelons, Muskmelons and Cantelopes. — Water- melons are rightly named ; they contain little besides water. In that little is oftentimes enough to induce serious illness. Like cucumbers, they are treacherous fruits, and sometimes betray their best friends. Muskmelons and cantelopes are more trustworthy and are more valuable. All these fruits are less liable to do injury when eaten as a part of the regular meal. Ckanbebbies. — A very pleasant and healthful acid is found in the cranberry. When stewed with sugar they are generally harmless, and by those of delicate digestion are sometimes eagerly craved. . Whortlebeebies, Blackberries, etc. — These berries, like peaches, can usually be taken in large quantities with only agreeable results. 30 J!ATING AND DRINKING. The medicinal character of blackberries, like that of tomatoes, has, I suspect, been somewhat exaggerated, but that they are of great value in summer food there is no question. PEUITS NOT VEBY NUTRITIVE. The amount of actual nutriment in many of the most luscious fruits and vegetables is exceedingly small, and enormous quantities must be eaten in order to make a meal of them, and of some varieties no amount that can be swallowed will very long satisfy the appetite. To judge of the value of food by the amount of its nutriment merely, is as unscientific and as unphilosoph- ical as it would be to judge of the character of men by their weight avoirdupois. These watery and luscious fruits and vegetables serve not only to quench the thirst, to supply acids and sugars, etc., to the body, but also to stimulate the appetite for other and more substantial food, and to assist its diges- tion, and very likely to enhance, in ways that are past oar finding out, its assimilative power. Fruits do not contain more than five per cent, of solid matter, and very little of the albuminoids ; but they contain considerable sugar and acid. They are valuable in diet for their saline ingredients, for their sugars and acids,_ and for the flavor and zest that they give to other food. Kipe, luscious fruits of nearly all the leading va- rieties, can be eaten in their season, by those in average health, in enormous quantities, to the full extent of the appetite and between meals, not only without injury but with very great benefit. To this rule there are individual exceptions. .'•M ■ FKUITS. 31 TROPICAL PBtriTS. The value of tropical fruits, like the beauty of tropical flowers, has in some respects been greatly exaggerated. Some of the flowers that grow in southern lands are indeed beautiful, and a few of them are magnificent, but the average effect of a tropical forest or landscape is far less attractive than that of the gardens, the fields, and the hedges of the North. Just so, some of the fruits of the tropics are rich and tempting, and one or two varieties are luscious beyond anything that we have in our colder clime, yet as a whole they bear no compar- ison with the produce of the orchards of England or America. Between the warm and the cold climes there is in this respect less difference than has been supposed. The grape, the peach, and the apple, wiU outweigh in the variety of uses nearly all the fruits of the tropics. The best of the tropical fruits are the orange, the du- rion, the litchi, the mangosteen. Orangses. — The orange is to us as familiar as the apple, and strange as it may appear, costs less than the applei' in the New York market. In the South, oranges, and indeed other fruits, are eaten early in the morning, soon after rising, or as a part of breakfast. The old Spanish proverb, " Fruit is gold in the- morning, silver at noon, and lead at night," could only have originated in a warm cHme, for it cer- tainly does not apply to the latitude of Northern Europe and America. Except in the warmest weather, fruits are not desired at breakfast, and, to borrow a medical phrase, are not indicated. 32 EATING AND DEINSING. In the Southern States oranges and melons are morn- ing food ; and in Texas I observed that cantalopes ■were, in their season, on the breakfast table almost as regularly as the bread or coffee. The Dukion. — Of this fruit, we have a most enthusi- astic description by Mr. Alfred Wallace. He states that in the Malay Archipelago it is regarded by the natives as superior to all the many varieties with which they are favored. It grows on a lofty tree, somewhat resembling an elm. The fruit is about the size of a large cocoanut, is of a green color, and is covered with short spines, and is so heavy that when it falls from a height on any individual it produces a terrible wound. "The pulp is the eatable part; its consistence and flavor are indescribable. A rich butter-like custard highly flavored with almond, gives the best general idea of it, but intermingled with it come wafts of flavor that call to mind cream-cheese, onion sauce, brown sherry, and other incongruities. It is neither acid, nor sweet, nor juicy, yet one feels the want of none of these quali- ties, for it is perfect as it is. It produces no nausea or other bad effect, and the more you eat of it, the less you feel inclined to stop. In fact, to eat durionsj is a rare sensation worth a voyage to the East to experience." Eev. Mr. MeUen, formerly U. S. Consul at Mauritius, informs me that an exceedingly luscious fruit also grows there, which receives the name of " bull's heart." From his description I should judge that it was much hke the durion. He says that it is as much better than the finest custard as custard is better than hominy. Mr. Wallace fiu'ther says, " It would not perhaps be TEOPiCAL PEUn'S. 33 correct to say that the durion is the best of all fruits, because it cannot supply the place of the sub-acid juicy kinds, such as the orange, graipe, mango, and mangosteen, whose refreshing and cooling qualities are so wholesome and grateful ; but as producing a food of the most ex- quisite flavor it is unsurpassed. If I had to fix on two only as representing the perfection of the two classes, I should certainly choose the durion and the orange as the king and queen of fruits." While our mouths water over the descriptions of fruits that can be tasted only by those who make long and wearisome voyages, we can find consolation in the possession of the peach, the pear, and the strawberry. Bread Feuit.— The bread fruit tree, which grows, though never abundantly, in many tropical regions, is one of the most remarkable objects in nature. The fruit is of the size of a melon and is of the consistence of pudding. It may be baked, stewed or fried. It is eaten with gravy, with sugar, molasses, butter, or milk. Its taste is compared to that of mashed potato and milk, or when cooked with sweets, to a delicious pud- ding. Like bread and potatoes it becomes a standard food which is always useful, never injures, and of which we never tire. Lemons and Limes.- — The acid^in lemons and limes is not only useful against scurvy, but fulfills an excellent purpose in combination with fish of all kinds, and in the form of lemonade. Lemonade is a drink that for the majority is as health- ful as it is agreeable. 34: EATING AND DRINKING. Pineapple. — This veiy palatable fruit is less digest- ible than the orange, and must be eaten with caution, especially in debilitating weather. Bananas. — The banana contains some Uttle nutriment, and is not often injurious. CocoANTJT. — The cocoanut,when it arrives in this coun- try, is so hard that it becomes indigestible, and the milk is not particularly refreshing. It has been said that in those regions where they grow, the milk is much better and the nut itself particularly delightful. This state- ment does not correspond with my experience. I have taken cocoanuts from the tree and eaten them on the spot, and failed to discover the superiority that has been claimed for them when perfectly fresh, and the milk when drunk directly from the nut was to me rather sick- ening, although others were more pleased with it. For myself I should prefer the cocoanut after it has been kept for a nuniber of days. I may say also that the flavor of the orange, when eaten fresh from the tree, has been similarly exagger- ated-by travelers. Oranges, when taken ripe from the tree, remain luscious for a considerable time. Figs, Kaisins, -Dates, Prunes. — All these dried fruits are useful as well as palatable in their way, that is, as relishes or in combination with other food. They are injurious only to weak stomachs. The habit of forcing them down in large quantities in order to keep the bow- els free, is abominable. When eaten in large quantities it is well that they should be combined with some acid fruit, or at least with bread or meat. -NUTS — SUGAE. 35 The idea that figs are better when fresh from the tree on which they grow, is, if I may generahze from my own experience, another delusion. I have often eaten them when recently plucked and prepared for the table, and found them simply tolerable. It has become so fashionable for superficial observers to declare that the unfortunate dwellers in the temper- ate zones, know nothing of the lusciousness of the trop- ical fruits, that it is well to stop and inquire how much of truth there may be in the statement. NUTS. The walnut tree grows wild in the Caucasus and Him- alaya. There are a number of varieties. Nuts of all kinds contain considerable fat, and are hard of diges- tion. They are best taken in small quantities, and in connection with other food of a different character, such as fruits. They do less harm i^ter ;meds than on an empty stomach or just before retiring. Chestnuts. — Chestnuts contain a considerable nutri- ment, and by the peasants of the Apennines are some- times depended on for food. They are less burdensome to the stomach than walnuts. SUGAR. Sugar and molasses produce heat and fat, and also sustain the system in other ways that are not under- stood. They are much longed for by children, and they do 36 EATING AND DEINKINQ. them good. They are palatable — the strongest possible argument in their favor — and they supply the fat and the warmth that children need. The popular candies are frequently injurious, on ac- count of the bad character of the substances that are used to color them. ICE CKEAM. Ice cream, when made of pure milk or cream, and flavored without the aid of injurious ingredients, is not only harmless, but positively beneficial. It is very properly eaten in the evening or between meals, or at least as an accompaniment of hot food. An objection to eating it largely at meals, is that it cools the stomach, especially if it be deHcate to such a degree that digestion is hindered. The custom of combining ice cream with acid fruits is as wise as it is agreeable. WATER. Water constitutes, as we have seen, the principal por- tion of our food. It is the leading constituent of all our so-called solid food ; it is used by itself and in all our beverages. Fure water is never found, and only with great diffi- culty is it manufactured approximately pure by the chemist. It is without odor or color, and is therefore not adapted for drinking purposes. The purest of all water is rain water ; but this always contains more or less of organic matter, with nitric acid, ammonia and salts. WATER. 37 The ingredients of the majority of our drinking waters, are oxygen, nitrogen, carbonic acid. The waters of mineral springs contain, besides these substances, various salts of potash, iron, and soda, on which their medicinal virtues depend. Some waters contain as much as 15 or 20 cubic inches per gaUon of carbonic acid gas, and water thus impreg- nated are much more palatable than those that are en- tirely free from this gas. Ifard water is that which contains salts of lime, potas- sium, sodium, or magnesium. These salts are found in some waters in the proportion of from 10 to 15 grains to the gallon. It is believed that a moderate proportion of salts in our drinking water is beneficial, although hard water is very inconvenient for culinary or washing purposes, because the fat of the soap combines with the salty mat- ters in the water, and forms insoluble soap. Distilled wafer, though almost perfectly pure, is not agreeable to the taste, until it has been thoroughly agi- tated and mixed with common air and carbonic acid gas. This may be done by pouring it from one vessel to another many times, or by forcing common air into it. The water of rivers frequently contains a considerable percentage of organic matter. The water of the Missis- sippi, for example, when poured into a tumbler, is ex- ceedingly turbid, and if allowed to stand for a few moments, a considerable quantity of earthy matter set- tles on the bottom. It is strange how freely this water can be used in many instances with apparent impunity. The boatmen on the Mississippi drink as much as they want of it 38 EATING AND DEINKING. Tvithout fear. That it sometimes causes affections of the bowels there is no doubt ; and yet I have had opportu- nity to see that bad results occur only in exceptional cases. Water should be drunk freely dui-ing meals, and as often as thirst requires. ^ The doctrine that we shall not drink during meals because some animals do not, is so abominable, so unsci- entific, and so cruel, that it is worthy of being classed ■frith the dogmas of the medieval ascetics. SODA WATER Soda water is justly regarded as a peculiarly innocent beverage. Very few are harmed by it, and thousands in the country are refreshed and positively nourished by it. This compliment applies only to good soda water. The art of making soda water just what it should be is underrated, or, at least, is practised only by a few.- Those to whom soda water causes nausea or sick headache, need no advice of mine to abstain. T'ONDIMENTS. Condiments are substances that sharpen the appetite and stimulate the digestive organs, and aid in the digestion of ordinary food. The best known condiments are : Pepper, Nutmeg, Mace, Cayenne Pepper, Cloves, Cassia, Mustard, Allspice, Turmeric, Cumamon, Ginger, Curry Powder. Most of these condiments are natives of warm regions ; ' CONDIMENTS. 39 and it is a fact of experience that they are most needed, most desired, and most useful in those countries. They are used habitually in cold and temperate cli- mates, but not as a rule in large quantities. The Peppers which grow in the West and East Indies, consist of a volatile oil, a crystaUizable substance called piperine, or capsicine, starchy matter, gum, woody fibre, and salts of potash. GiNGEK is cultivated in tropical Asia and America. It consists of a volatile oil, resin, gum, starch, woody fibre, acetic acid, sulphiu", salts of potash, lime, and iron. TuEMEEic. — This is the tuber of a plant that grows, in India and China. It has a peculiar aromatic taste, and is of an orange yellow color. Turmeric is a leading in- gredient in curry powder . CuEEY PowDEE consists of a number of ingredients — among which are black and cayenne pepper, coriander seeds, ginger, allspice, cloves, turmeric, cardamom, fcenugreck and cumin. Of these turmeric, coriander seeds and black pepper, are the most important. Cori- ander seed and cardamom are suflSciently familiar. Cumin seeds strongly resemble caraway. Fcenugreck seeds are the produce of a plant that grows in India, Arabia and Sicily. Condiments are used in hot cUmates to an extent that greatly surprises travelers. Pepper and curry in enor- mous quantities that a Northerner cannot endure, are there used in combination with more substantial arti- cles. They seem to aid digestion, to have a cooUng effect, and to compensate for deficiency in salt. 40 EATING AND DKINKING. Common Salt. — Common salt is the most universal food of man. Salt was used by the Jews in their sacrifices, and by the Arabians was placed on the table as a special mark of hospitality. The Hindoos swear by salt, and the Abys- sinian gentleman carries a piece in his pocket, and takes it out and offers it to a friend to lick as a mark of respect and esteem. Among the Apingi tribe of Africa salt is; so scarce that ten pounds will buy a slave, and Du Chaillu thinks that the ulcers and diseases of the skin to which these people are subject are largfely caused by deficiency in this article. The deprivation of salt is one of the most terrible of calamities. In Africa tribes have been found who will sell a wife or a child for a smaU quantity. Livingstone says that the poor Backwains who are forced to eat roots without salt are troubled with indi- gestion. Milk and meat are in Africa found to be good substitutes for salt. Of all the continents Africa seems to suffer most from salt famine. It is not very complimentary to the state of the science of physiological chemistry to be obliged to con- fess that the function of an agent so indispensable as salt is not und-erstood. When we have stated that it aids in the digestion of other food, and in the processes of absorption and secretion, we have said all that we know and perhaps more than we know. SUBSTITUTES FOR SALT. It seems that these elementary substances, such as meat, milk, etc., which contain salts of potash and other mineral matter, are, to a certain extent, substitutes for RELATION OF FOOD TO WORK. 41 salt ; tliat when these substances are used in abundance less salt is needed, and the want of it is better endured. Pepper also is said to have the same effepb. The appe- tite for salt, as we aU know, depends on the quality of our food. Chivi. — ^The Indians of Javita, South America, pre- pare a substitute for salt, of muriate of potash, caustic lime, and the earthy salts. CuPANA, Chinia, Cieo. — The Indians of Javita also make a salt by reducing to ashes the seeds of the plant cupana. The seeds also are carefully scraped, mixed with cassava, covered with plantain leaves, and allowed to ferment. Chinia, another salt, is made by reducing to ashes the spadix and .fruit of the chinia palm tree.^ In Madagascar salt is obtained from the sap of the oiro palm tree. The mUk of the cocoanut tree also contains saline matter. We who live in a land where salt is not only cheap, but the very cheapest article of food, so that not to be able to earn it is regarded the expression of extreme poverty, can with difficulty realize the condition of the inhabitants of Central Africa, where only the very rich- est can afford to have salt at their meals ; where chil- di-en, when they can get it, suck it Jike sticks of, candy. KELATION OF POOD TO WORK. Various and interesting experiments have been made to determine the relation of food to the amount of work 42 EATING AND DKINKING. that it is capable of accomplishing. Analysis of the different alimentary substances, will teU us the percent- age of carbo-hydrates, of albuminoids, and so forth, but it does not tell us just what percentage of these are as- similated, nor can it explain the manifold changes which these must undergo in the body. Hence any estimate of the amount of work, that food is capable of, based simply on their chemical constitution, would be imper- fect and erroneous. The usual method of determining^ the relation of the different kinds of food to work is to estimate the amount of heat they give off when burned. Heat is regarded as an equi.valent of motive force, and the food that gives off the raost heat is the best for giv- ing heat 'and motive power to the body. The estimates thus found must, at best, be only approximate. They make no allowance for the changes that may take plaea in the body, and to which I have referred. Moreover, cellulose of vegetablte food is indigestible, though it burns readily and evolves much heat. On the other hand, the albuminous elements of food do not give out their entire force iii the body. Making allowance so far as possible for these facts, we may arrive at an estimate of the work power of food that may, perhaps, be approxi- mately accurate. Thus it has been estimated that the latent force of 700 grains of food — less than 1^ ounces of butter — is suf- ficient to raise 1,000,000 pounds one foot high in one day. Practically it is found that only about half of the latent force of food is evolved in the body. In all me- chanical arrangements — such as the steam engine — the proportion of wasted force is ten times greater than the force. that is utilized. BELATION OF FOOD TO WORK. 43- It has been estimated that three fifths of the force evolved by food is used in the acts of respiration and the movements of the heart. It is believed that the leading function of nitrogenous food — meat, fish, bread, etc., is to repair the tissues of the body. This view is rendered probable by the ex- periments on animals, which show that with a purely carbonaceous diet — fat, oils, sugar and starch — the weight is rapidly lost. That it is possible to live, after a sort, on a diet very largely carbonaceous, is proved by the experience of the wretched millions of China and India. Then again experience demonstrates that it is not enough that the food should contain nitrogen : it must contain it in a variety of combinations ; hence the necessity of a variety of food. It is not improbable furthermore that nitrogenous substances may aid ia the digestion of the carbo- hydrates. It is certainly proved that articles of food, which are the same in chemical constitution, differ widely in their capacity to sustain life. Carbo-hydrates — ^fat, starch and sugar — ^not only serve to warm the system, but they also repair the tissues, especially the adispose tissues. The heat pro- ducing power of fat is believed to be three times greater than ijhat of starch and sugar. They also assist in the digestion of nitrogenous food. Here, then, is another argument for variety in our diet. The question whether the tissues of the muscles are actually consumed in muscular exercise or only the blood, has received various answers. The belief has been that force is developed mainly 44 EATING AND DEINKING. by the oxidation of the carbo-hydrates in the blood, and that when abundant food is given the muscular tissue is not changed. Prof. Austin Flint, Jr., thinks he has shown, by very careful experiments made on Weston, the famous pedes- trian, during one of his greatest feats, that very severe exertion is attended with " consumption of the muscular substance." Whether this consumption of the tissue of the muscles takes place during the ordinary muscular exercise, when the food is various and abundant, is yet to be shown. Filially, I may remark that the belief is not unreason- able that the animal heat is produced by the transfer- rence of the potential energy of the food in the blood into muscular power. CHAPTER IV. EATING CUSTOMS IN DIFFEEENT PARTS OF THE WOELD, WITH CONCLUSIONS theeefeom:. , The facts contained in this chapter have been obtained from a pretty exhaustive study of all possible sources of information concerning the eating customs in all parts of the world, where man has penetrated, and the gen- eralizations are drawn from a careful sui-vey of the facts considered in the light of recent science. 1. The customs of different peoples in regard to eating and drinking are as diverse and opposite as their customs in regard to religion, government, and social life, and nearly all forms of organic life, when used as food, seem to he capable of sustaining life. I have only space, under this head, to refer to a few of the more noteworthy diversities of custom. In Persia, horse flesh and camel's flesh are the great dishes. The Tartars live on milk, butter, and oatmeal. The Thibetans, rich and poor, are meagerly fed. They have little rice, or wheat, or fruit, and depend on black bar- ley ; from which they make tsamba, their leading article of diet 4:6 EATING AND DEINKING. The staff of life in East Africa, is ugali, a porridge made of boiled millet, or maize flour. The North American Indians live on the flesh of ani- mals obtained in hunting, fresh water fish, and others obtain corn and fruits. The African Bushmen eat roots, bulbs, garlic, the larvse of ants, locusts, grasshoppers, lizards, and anything else they can get hold of. The Hottentots pick vermin from each other, and eat them as a matter of course, declaring that the best way to get revenge for their eating, is by our eating them. The AustraUans eat the prairie rat, the flying fox, and the ant eater. The Malayans delight in a species of bat. The Bengalese eat cow or buffalo beef, pork, pigeons, and in times of scarcity, snakes, frogs, ants and rats. Enormous fish, that we know nothing of, are caught in tropical rivers. I can only mention the " Baggar," the "Bayard," and the "Coor ;" the catching of which is so graphically described by Baker. The Chinese eat sea slug, which is regarded as a great deUcacy ; " and birds' nests, sharks' fins, and fish roes. The poorer classes subsist mainly on rice and fish ; but sometimes resort to the heads and entrails of fowl, earth worms, mice, dogs, cats, frogs,' horse- flesh, unhatched ducks, and snakes, and rotten eggs. The popular conception that dogs, and rats, and mice are a prominent article of food in China is erroneous. In this country who would think of eating water- melon seeds, excejpt when on the borders of starvation? But Mr. Hue tells us that in China they are an object of daily consumption. They are taken before meals, and between meals : and when it is desired to treat a A EOTAL FEABT IN AFEICA. 47 friend or caller. Everywhere they are sold ; and chil- dren run to invest their little money in them like so many sugar-plums. " The consumption of them through- out the empire is something incredible, something beyond the limits of the wildest imagination." A merchant who was invited to a feast of the Green- landers, counted the following dishes : "Dried herring; dried seal's flesh, called mikiak ; boiled auks, part of a whale's tail in a half putrid state, which was considered a principal dish ; dried salmon; dried reindeer venison; preserves of cranberries mixed with the chyle from the maw of the reindeer ; and lastly, the same enriched with train oil." A BOYAL FEAST IN APEIOA. Du Chaillu gives an interesting description of a royal feast that was Igiven to him by King Obindji, on the banks of the Ovenga Eiver, in Equatorial Africa. To the furious beating of drums, twenty of the king's wives came forth, each bringing a dish which they placed on the mat. The first course was " boiled elephant, that had been cooking since the day before, to make it tender. Next appeared hailed crocodile, the broth of Vhich was well seasoned with lemon juice and pepper. A monkey roasted whole followed, wonderfully resem- bling a roasted baby. A. wild feoarwas the next surprise, with a strong flavor as if it had been killed many days before. Then came the less astonishing huffdo ribs and ibrtgue, which was followed by smoked otter, antelope, and the Ught gazelle. 48 EATING AND DRINKING. Instead of bread, plantains were placed in a large dish in the center. The meats were followed by the fish, as manaters, mul- lets, and turtles. As a kind of second course, boUed gorilla was pre- pared by a friend of Du ChaiUu, and "also a dish made of part of a large snake cooked in leaves." Du ChaDlu gives his impression of each article. The elephant was abominably tough ; the crocodile soup was not at all agi'eeable, although the taste was extin- guished by pepper ; the wild boar was putrid, but the Africans "thought it exquisite ;" the otter he did not like, and the buffalo he hardly touched ; but the mon- key was " perfectly delicious," as good as the best of venison. The Arabs almost depend on " waJcer," which is called in Ceylon and India " Barmian,'' and '^'Bandikai." The pods of this are dried, and are mixed with almost every kind of food. Besides this they have the " regie," a juicy, brittle plant. A great staple with the Arabs is " dhurra," a kind of grain, of which they make " melach " and " abrey " cakes, which they eat on their long journeys. In other lands all sorts of strange animals and bu-ds are eaten^— parrots,- which when old are tough, but when young are Uke the pigeon ; the wild boar ; the ass, which has been highly valued ; the donkey, not unlike the . horse ; the hyena ; the leopard ; the reindeer ; the tiger, which the Malay beUeves to be a specific against disease ; the panther ; the wild cat ; the bear ; the lion and the jaguar; the beaver ; the kangaroo, the tail of which makes a soup in comparison with which that of ox tail is tame enough. TEOPIOAL PKODUCTIONS. 49 Nature is continually surprising us witli singular freaks and caprices in her productions. In the interior of Brazil sweet lemons are found, which resemble in outward appearance, the ordinary sour lemon. Sour honey is also produced by a certain species of bee in South America. There are many tropical fruits that rarely, if ever, reach the North, but are known only to travelers. Among these I may mention lansat, jrnnbon, jack, ram- butan, blimbing, and mangosteen which is by some re- garded as the best of the tropical fruits. In the West Indies the alligator pear is much valued ; Brazil produces the elegant custard apple. In the West Indies also grows the mamma apple. A fruit of Guinea is the akee. One of the finest luxuries of the East, is the litchi, which ranks nearly on a par with the durion and mangosteen. Other fruits of warm climates are the lucuma, maqui, hog plum, sapota, star apple, chupon, guava, and tamarind, whose peculiar acid is so delightful to invalids. Among productions of the tropics that are little known among us, may be mentioned the koola nut, which is said to be very nutritious ; the saloom and neb- buk, that grows ia Egypt ; motsouri and nijii beans ; the mogametsa, a bean with a Uttle pulp around it; the m/yriM, a bright red bean, and the manioc and plantain, which are to Africa what bread and potatoes are to Europe and America. Travelers speak also of the marolo, "small and wholesome, and full of seeds, like the custard, apple ;" the mamosho, or "mother of morning," described as "juicy and delicious;" the cashew apple, the "mawa;" the " memgongo," A fruit much resembhng a northern 50 EATING AND DBINKING. apple or pear ; and the mponko, that resembles our melon. Mangabas, goyobas, jambos, mammoons, cajas, cajus, cambocas, aracas, maracuja — these are some of the fruits of Brazil that to Northern ears convey no definite mean- ing, but which are rich, delicate and refreshing. Trav- elers in South America also speak of the manirito, the madrona, a deUghtful sub-acid fruit, and the cacaita, or monkey cacao-bean. CLAY EATERS. Not only organized but unorganized substances seem to be capable of sustaining life. Thus the Ottomac In- dians of South America eat earth, which they swaUow daily in large quantities, for months in succession. This earth is a fine unctuous clay, of a yellowish color, and when hardened has a little red color, due to the oxide of iron. During those seasons when fruits are scarce these Indians subsist almost entu-ely on this earth, which they make into balls 'and consume in enor- mous quantities, and take very little else besides: Similarly the negroes on the coast of Guinea eat a yellow earth caUed caauac. The inhabitants of Java eat cakes made of " reddish and somewhat ferruginous clay," but are injured by it and perceptibly lose their flesh. The Ottomac Indians seem to thrive on dirt-eating, for Humboldt describes them as " men of a very robust constitution," but they do not take much exercise. The negroes of Gambia mingle clay with their rice. ^ The conclusions to which Humboldt arrives, are, that the habit of eating earth is confined to the tropics of both hemispheres j that the positive nutriment in these EVOLUTION OF FOOD. 51 earths must be yery small indeed, and that it acts rather to appease hunger,. and stimulate the secretion of gas- tric juice ; that some tribes eat it from necessity, but others from cjioice. It seems almost necessary to accept the view that these clays do contain positive nutriment which in some way becomes assimilated. The General Law of Evolution is allied to Positive as well as to Negative Food. In the general history T have given of the method by which men have arrived at their present knowledge and use of food, it follows that the law of evolution may be justly said to apply to food, and may explain and con- firm its history. The history of food, like the history of stimulants and narcotics, like the history of aU organic nature, is the history of a struggle for existence,- of con- tinuous differentiation, and multiplication, and adapt- ation to changes in soil, climate, and human progress. In proportion as man has multipUed and advanced, and become subdivided into tribes and races, in that proportion has the food on which he has subsisted been multiplied in variety j and in proportion as he has risen from savagery toward civilization, in that propor- tion has his food improved in quality as well as in quantity ; and side by side with modern refinement in the art of cookery there has been a great increase of nervousness and nervous diseases, that has made tempt- ing diet a necessity. All the vast institutions ■ of mechanical skill, in the forms of trades and specialties, would have been hamp- ered and retarded had not food correspondingly com- bined to meet the varying wants of all. 52 EATING AND DRINKING. The early savages, we have seen, must have slowly or rapidly starved on barks, and leaves, and berries, with occasional feasts of meat, or, fish, or fruit. The ancient civilizations rejoiced in tables that were then called abundant and luxurious, and at the banquets of the Roman nabobs all the known world was laid under ex- plicit and extravagant contribution ; but the Eoman feasts were tame enough in comparison with the daUy needs of the average European or American. As man has migrated from land to land, and sea to sea, in that proportion he has found new, and different, and peculiar varieties of food adapted to his wants in the climates in which he has taken his abode. Climates also have changed from age to age, and the materials of food which depend on climate have changed with it ; and correspondingly, man's desires as well as his needs have also changed. The evolution of food has kept place with the evo- lution not only of agriculture and commerce, but of social life, of religion, of mechanical skUl, invention, and of morals. As man has cultivated more he has desired more ; as his taste has become sensitive and capricious, the means to gratify that taste have arisen. In the darkness of the Middle Ages, gluttons were abundant ; but they indulged their passions with a limited and oftentimes untempting variety of food. For ages certain nations of Europe lived largely on pork, and their intellectual achievements well corresponded. In America, the varieties of the raw material food are greater than in any other continent, and in addition, nearly aU the desirable products of the world are brought to our shores. LAW OF ETOLUTION APPLIED TO FOOD. 53 THE LAW OF EVOLUTION APPLIES ALSO TO NEGATIVE FOOD. Stimulants and narcotics have likewise multiplied and improved with the advance of the race, and are now used in their greatest variety in the most highly civilized nations. To the divine Saoma has succeeded wine, and wine has differentiated into hundreds of varieties that the ancient world knew not of. The opium and hemp of the ancients have been va- riously modified by modem cultivation, and are to a certain extent replaced by tobacco, coffee, tea, and choc- olate, with their many imitations.* In accordance with the general law of evolution, va- rieties of food that were formerly held in esteem, are now little used ; according as new and better varieties arise, more pleasing modifications are developed with the advance of the race. The gluttonous feasts of our forefathers would hardly be attractive to modern Londoners or Parisians. Ages ago, sage was a common drink in Europe, but that, and numerous other herbs, have yielded to tea and coffee. Already we have seen how rapid has been the evolu- tion of cereals and fruits, and how many improved va- rieties are required, which in our fathers' day had not been born. The fruits and vegetables of our modern markets are as much richer and more varied, than those of the middle ages as the civilization of the 19th century * For a more detiiUed description and history, see my work on Stimulants and yarcoticSy of this scries. 54 EATING AND DRINKING. is more complex, and more refined, than the civilization of Mediaeval Europe. In the time of Henry TEII. there were no cabbages, car- rots, nor any esculent roots in England, and about this time artichokes, apricots and plums first appeared. Among the articles of food that were once popular, but now, for some reason, have lost their popularity, are the lamprey, once a great delicacy ; the sturgeon, of which the Greeks and Romans were so fond ; the dolphin, which is now regarded as insipid. The por- poise, once most popular, is now almost forgotten. Among birds the bustard and thejlamingo were greatly lauded by the ancient Romans. The majority of the inhabitants of- the world are underfed. Of the twelve hundred million inhabitants of this globe only a very small fraction systematically get enough to eat. The almost universal condition of exist- ence is poverty, and in no other direction is poverty so widely felt as in waat of food. Clothing of some kind, cheap or luxurious, and enough for health, is enjoyed by all races from the lower savages to the more enlightened. A suit when once provided lasts, long, and when lost or worn out, can easily be replaced by some other, which is aU that is needed for protection if not for luxury. There are very few, and those are usually only of the very poorest classes in civilized countries, who need to suffer from cold through lack of clothing. Food, on the contrary, is usually more or less difficult to get, and civilization is always expensive. Even when food is aljundant in quantity the quality may be so bad that those who subsist on it are poorly nourished. In this matter of diet extremes meet ; the savage goes hun- THE WOBLD UNDEEFED. 55 gry because he is too lazy to go after food, or, perhaps, because it cannot be found ; the wealthy and cultivated restrain their appetites because fashion — more tyranni- cal than hunger even — enjoins it ; or because they are so absorbed in intellectual pursuits that the cry of the passions is not heard. The greatest gluttons may be chronically underfed, for we are told that the Siberians, the Kamtschatkans, and the African tribes and savages generally, who, at their feasts, appear to be enormous gluttons, go for days at a time without anything to eat ; and there are mil- lions and millions who live and die in this world with- out ever having known a really substantial and every way healthful meal. Among enlightened nations only a small minority can afford to buy the best of food. The great mass must be content with what they can get, arid cooked in a manner at once unscientific and unpalatable. Oarlyle said to Emerson that the best thing he ever heard of America was, that there every- one could have meat for his dinner — a remark which suggests very painfully the condition of the greater portion of the population of Europe^ — and yet of the 40,000,000 inhabi- tants of the United States — ^the most favored nation in the world in regard to food — there are probably not more than one million who can or do systematically live well. In Great Britain — that has given the world the best civilization it has yet seen, and where among the higher classes the art of dining has been carried to its highest perfection — hundreds of thousands rise each morning knowing not where they shall get their breakfast, and 56 EATING AND DEINKING. there are very many millions who have never tasted and never will taste a generous and varied dinner. In the United States the diet of the poorer classes in the great cities is so abominable that the physicians of the public institutions of charity find great difficulty in treating them — with satisfaction. Our farming pop- ulation, who raise their own food, live much worse than is supposed. Pork, cabbage and potatoes are the great staples, and in thousands of families a piece of tender beef steak would be as much of a rarity as a durion of the Malay Archipelago.* Thus we see that from the starving millions on the Plains of Persia, whom despotism and ignorance keep perpetually poor, and the bigoted castes of India dying by millions amid the cattle which their rehgion forbids them to eat ; and the lazy Siberian, too short-sighted to accumulate in seasons of plenty against seasons of scarcity ; and the wretched African tribes, decimated by disease brought on by life-long deprivation of the com- monest necessities, to the gay lady of fashion, who goes hungry away from a bountiful table, lest she might become gross, or have blotches on her face, and the hard toiling brain-worker, who forgets whether he has dined in the excitement of his book or a problem, or whom crazy hygienists have taught that prolonged hunger is the true prescription for health and long life — through all grades of humanity inanition is the rule, repletion the exception. Among the civilized portions of society of modern * The statements on this topic, though necessaril; given with considerable absoluteness, are not made at random. They are based on careful ttudy of those works that desciibe the manners and customs of di£rerent countries, and on the statistics of Europe and America. GLUTTONY A VICE OF THE PAST. 57 times, the number of those who often overeat is very- limited. In the old civilizations of Persia and Kome, and with our forefathers in Great Britain and Northern Europe,* gluttony was a prominent if not universal vice among those who could obtain the material on which to be gluttonous. The vice is a relic of savagery, of a social state when food was scarce, or at least uncertain, and men were tempted to gorge themselves in order to compensate for the famines of the past and anticipate those that were to come. Then again, savages have so lit- tle intellectual culture and so few amusements, that the gratification of appetite has limited restraints. With the rise of modern culture, with the vast mul- -, tiplication of books and newspapers, with the varied opportunities for literary and social activity and re- creation, in lectures, public worship, in political gather- ings, in the multitudinous cares and details of science, art, scholarship, education and trade, and with the vary- ing and incessant demands of fashion, and, in connec- tion with all these activities, with an improved moral ' sense and consequent growing repugnance to coarse vices, crimes of every kind are either disappearing, or, retaining their confined essence, assume a more refined character. Thus the love for bull fights and the gladi- atorial arena, have given way to the pantomime, the tragedy, and the ballet. Thus also in the best circles, intemperate drinking, which only half a century ago was almost universal in the leading classes of Great Britain and the United States, and was held in esteem, has now become among these classes an exceptional * The word " gOrmand" is said to ba derived from Gorman, a gluttonous - king o£ the Danes. The Normans were more temperate than the Britons, but were won over to habits of gluttony by the people whom they cpnciuered. ^ 58 EATING AND DEINKDJO. vice, and is held in great reproach. Ardent spirits have, to a certain extent, been replaced by the milder stimu- lants, tea, coffee, and chocolate. Similarly, also, the dis- gusting habit of tobacco-chewing has slowly yielded to tobacco-smoking, and carrying the refinement further still, the filthy pipe has been cast aside in favor of the beautiful meerschaum, the elegant cigar, or the light cigarette. All these habits, from the sturdy women of Queen Bessie's reign gulping their beer by the quart, to the fashionable lady of "West End or Fifth Avenue, deli- cately sipping her weak chocolate or tea, have a common basis, but the difference between the former and the lat- ter represents the difference between the coarseness of i the sixteenth and the culture of the nineteenth cen- ''/' turies. Civilization has vices enough, but they are different from those of barbarism in their manifestation if not in their purpose. The corruption- — which is the one great vice of a high civilization — is simply a refined method of robbery. The man who in the 14:th century would have waylaid a stage coach and murdered the passen- gers, now embezzles his employer's -funds, steals from the people by lying advertisements, and robs the treas- uries of cities, nations, and railroads. OVEEEATING VEBY BARELY A CAUSE OF CHRONIC DISEASES AMONG THE INTELLIGENT CLASSES. Earely, if ever, do I see a patient with chronic disease that has been induced or aggravated by overeating. Temporary disturbances in digestion are continually caused by carelessness in the use of indigestible fruits and other substances ; but permanerd ill health, as a THE EULING PEOPLE FLESH EATERS. 59 result^ excessive ewtin^^good food, in cultivated, iQteUigenT^aSMS^s^so rare thatTTo not Temember gver to ha sa^een a case. The vast and increasing army of paralytics, dyspep- tics, consumptives, nervously exhausted, and insane, is |filled,_jftot by those who overeat, but by those who ridereat.*^ The great difficulty that practitioners, of ' chronic diseases especially, encounter is in getting their patients to take sufficient nutriment. Very much of the benefit that follows traveling, change of residence to the seaside or the mountains, muscular exercise, ' electrical treatment, and various medicines, is due to, ^ and is measured by, the increase of the appetite, and corresponding increase in digestive capacity. Many of our most valued medicines — cod liver oil, cream, phosphates, and iron — act directly as food, and owe their value to their nutritive powers. To restrain debilitated patients from eating in our days is as unscientific as it would be to bleed them a few ounces daily, as was formerly done in such cases, V and would have a similar effect to increase their de- bihty. The most vigorous, independent, and energetic people in all parts of the world are flesh eaters, while those who live exclusively or mainly on fish and vegetables are inactive, phlegmatic, and stationary. This conclusion is clear and inevitable from the facts of history, and well accords with our knowledge of comparative anatomy, and with common observation. * I do not forget the well recognized disease, boulimia, wMcli consists in abnormal and unappeasable appetite ; nor that epilepsy has for one of ita symptoms or results a morbid desire for food that demands restraint. 60 EATING AND DEINZING. Theoretically, it would seem that the flesh of lower animals, which so closely resembles that of man, would be of all food the easiest to assimilate, and the best form of nutrition. Experience demonstrates the cor- rectness of this theoiy. The strength and working power of human beings is, to a certain extent, propor- tioned to the quantity of animal food that they can habitually digest. / The most powerful nations and the greatest and best men everywhere are flesh eaters. In all civilized coun- tries the leading classes who control the ciyihzation, have never been vegetarians, and so far as can be learned this statement is true for aU the older nations — Assyria, Egypt, Greece and Eome ; that it is true of all the great nations of modern times no one will question.* Among the savage and semi-savage races we find that the energetic, . the warlike, and the migratory, are flesh eaters, while those whose dependence is ex- clusively on fish, vegetables or fruit, are comparatively passive, timid, peaceable and stationary both in char- acter and locality.f Contrast the wild and ugly- tribes of Central Africa, who make murder a pastime, and keep their country half depopulated by cruel wars : the bold and adventurous herdsmen of the South Amer- ican pampas ; the fierce and wandering Arab of the desert; and the murderous aborigine of North America, and the well-to-do classes of civihzed lands — aU of whom are hberal or exclusive flesh eaters, with the * It has been calculated that in Prance one sixth of a pound of meat ia daily consumed ; tke average for London and New York is about half a pounds tl do not overlook althoush Ibave bere no room to describe the elements of race, climate, goycrnment, religion and education, all of wbicb more or leas co-operate with diet in making nations wbat tbey are.

The law is just as fixed in its application to the lower animals. It is stated the bears of India and America that live on acorns are mild and tamable, while those of polar climates, that feed on .flesh, are fierce and im- tamable. Even our domestic animals advertise their diet in their faces, and any one can tell a batcher's dog as far as he can see him. Enough is known on this subject to enable us to know a priori, that the German tribes who overthrew the Boman Empire could not have been vegetarians or fish eaters, and -that the great Grermano-Scandinavians \yho colonized Great Britain and North America, and sent their commerce to every ocean, must have been a beef eating race. CANNIBALS MOEE COUEAGEOUS AND ACTIVE THAN VEGETAKIANS. Human flesh seems to agree with those who eat it ; 62 EATING AND DBINKING. it is certainly far preferable to a purely vegetable diet. Du ChaiUu says that the Fans — a cannibal tribe who eat even those who have died from sickness, and wiR steal bodies that have been long dead, — are " the finest, bravest-looking set" of negroes of the interior of Africa. Tribes that devour human flesh are by no means, however, the most cruel, or the most degraded speci- mens of humanity. Cannibalism exists in different parts of the globe, and in very different races. It is stated by Abd-allatif, physician of Bagdad, that in Egypt, in the 13th century, in a season of great scarcity, the habit of eating human flesh spread through aU classes. At first it caused amazement and horror ; but the habit gradually extended until people of wealth and position regarded human flesh as a treat, and secreted it in stock against hard times. It was cooked in various ways. Of the poorer classes, large numbers were destroyed in this way. Fhysicians were in especial demand. They were sent for on pretense of consultation and were seized and devoured.* Eeade, who has traveled among cannibals, expresses the same views. Says he, "A cannibal is not neces- sarily ferocious. He eats his fellow creatures not be- cause he hates them, but because he Ukes them." Even in the hottest climates meat seems to be re- quired for those who toil hard. GOUAMBA, OK MEAT-HUNGEB.
