Considerable delay has occurred in the issue of this edition, as the pressure on his time, from some other work, prevented the Editor from undertaking, at an earlier period, that thoroug;h revision of his Clinical Manual which a new edition of a book of this kind necessarily demands after the lapse of a few years. Every portion has been revised by the original contributors and by the Editor himself: such additions and alterations have been made as seemed desir- able. Large sections, here and there, have been entirely re-written, and the number of illustrations increased from 85 to 160. These changes have led to an increase in the size of the book : althouo;h in a sense this is to be resetted, it could scarcely be avoided. The plan of the book remains unchanged. It is designed to afford such assistance as students, actually working at Clinical Medicine, might seem to require. It is hoped that it may continue to be useful to them in their clinical work, even after they have completed their course at the schools. The manner of using this Manual will depend on the subjects brought up before the student in the course of clin- ical instruction, and on the way it is employed by those teachers who may recommend it as helping to lighten their labors in the details of clinical teaching. In the absence of any such guidance, the student is recommended to read the first three chapters : from these he will learn the scope of the work, and he will then be able to select for himself, with VI PREFACE. the aid of the Index, such portions of the Manual for con- secutive reading or for special reference and consultation as his requirements from time to time seem to demand. It will be seen at a glance that this book does not aim at sup- plying any short and easy road to medical diagnosis : its object is to guide the student to a careful examination of the symptoms in his patient, and to supply information as to the methods and results of clinical investigation. To inter- pret these aright reference must often be made to various systematic treatises : some bibliographical notes are appended to the chapters to aid the student in this important part of his inquiry. The Editor has to acknowledge much assistance obtained from many friends versed in special departments of medicine : he would be only too glad to enumerate their names were it not that this might imply a greater responsibility than it seems fair to impose on them for their kindly help. Dr. John Wilson has supplied some additional drawings for this edition : these, along with all the others, are acknowl- edged in the list of illustrations. To two of his former hospital assistants — Dr. Malcolm MacMurrich and Dr. Robert Stevenson Thomson — the Editor's thanks are due for their aid in revising the sheets: the Index for this edition has been prepared by Dr. Mac- Murrich.

THE PHYSIOGNOMY OF DISEASE. In examining for medical purposes a patient affected with some bodily disease, it is of importance for the inquirer to have before his mind from the first the nature and the scope of the inquiry proposed, and not to be misled by any of the merely conventional phrases or forms of thought under which plausible fallacies and rash generalizatioDs are so prone to hide themselves. This remark applies with peculiar force to the investigation of the more external or physiognomic characters of diseases, because it is in dealing with these that the phy- sician is under the strongest temptations to appear wise at all hazards, and thus to formulate his knowledge (or his igno- rance) under terms which may or may not be correct as regards the individual case before him, but of which he would find the exact definition extremely difficult or impossible. Thus, it is very easy in a particular case to pronounce the patient " of a phthisical aspect," or " of a gouty habit," or "strumous," or of a rheumatic or other "diathesis," or to say that he has a well-marked " malignant," or " cancerous cachexy ;" and any one of these expressions may, in the particular case, indicate something that is really true, while, nevertheless, the expres- sion itself is altogether objectionable, and devoid both of real accuracy and scientific value. What the clinical observer has to do is not to grasp at a hasty generalization, but to note details of positive fact, and out of these to evolve the elements of a sure diagnosis. The statement that the patient has some peculiar and specific constitutional morbid tendency or bias is not, in any case, the statement of a fact, but of an opinion, and sometimes of a very insecure and fanciful opinion. Such a statement, therefore, should never be found among the pre- 2 14 THE PHYSIOGNOMY OF DISEASE. liminaries ; iH'obably, indeed, rarely even in the more advanced stages, of a hospital report ; inasmuch as even when true in fact, it is an inference based upon many, and much simpler, facts which ought to have been separately noted. The same principle holds, perhaps still more strongly, as regards the so-called " temperaments " — sanguine, bilious, nervous, etc., and all their more complex varieties. Without discussing here at all the amount of truth, or of reality, underlying these expressions, it may be certainly affirmed that their relation to particular diseases is almost wholly illusory ; and therefore the statements in which the elements of a diagnosis, so to speak, are concerned, should be as sim2:>le and precise as pos- sible, and should certainly not involve any general doctrine or theory of the disease and of its causes.^ Nevertheless, it is quite true that diseases, considered as disturbances of the physiological course of a healthy life, are often marked by incidents which leave indelible traces not only in the history, but on the physical structure of the body ; and it is the study of these, properly speaking, which ajffords to the well-informed physician almost the whole basis of objec- tive fact out of which a morbid tendency, or diathesis, can be inferred with a fair amount of probability. In other words, diathesis, as a study of facts, in an individual case, is an inference either from previous facts in the history indicating deranged i)liysiological function, or from manifest structural changes, the result of these; Avhereby we are enabled to estab- lish, but only as a presumption founded with more or less probability on the evidence, the existence of a tendency to sim- ilar changes, or changes of some allied order, in the future. In other words, the proof of diathesis is essentially the proof of disease; but, it may well be, disease in its earliest manifes- tatitms and least notable forms. There is a whole group of diseases, for example, which affect 1 The admiralile lectures of Mr. Jonathan Hutchinson — "The Pedigree of Disease," London, 1884 — ])ul)li.slii;d since this paragraph was issued in the first edition of the pres- ent work, do not app(;ar to tlie avithor essentially to modify anything herein set forth, hut rather to confirm the methods of procedure ahove insisted on. (See especially the remarks on temperament and diathesis at pp. 22, 23, 29.) The position taken hy this dis- tingui.shc^d investigator may he indicated hy two very hrief extracts, as follows : "We may perhaps define the term lemjyerament as applicahle to the sum of the physical ])ecu- liarities of an individual, exclusive of all definite tendencies to disease. . , . If there he a distinct jnoclivity, we must then use a stronger term, and speak of dialhesis.^^ "Temperament — the original vital endowment of the individ\ial — is iinquestionahly a real force, ami one which we would most gladly recognize and estimate if we could. The Bcei)ticism which I have been expressing applies not to the reality of the thing, liut to our ability to discriminate it" (p. '.H)). The whole work, in fact, although perhaps not Huitable for beginm-rs, may be commended to advanccil students as a commentary on lh(! rules ami methods of diagnosis recommended in this chapter. DIATHESIS — SENILE DECAY. 15 the human body chiefly or exclusively during its period of growth, whether of early infancy or of adolescence ; and another group, the first approaches of which are usually observed only along with, or succeeding, the physiological signs of senile decay. As regards the latter group, it may be said with truth that physiology and pathology are inextricably intermingled. A too early arxus senilis, the premature development of " crow's feet " at the outer margins of the eyelids, wrinkles in the skin of the face, diminished sensibility of the retina, or early presby- opia; still more, the well-known changes in the arteries, twist- ing or rigidity of the radials, etc ; falling or grayness of the hair, diminution or loss of sexual activity, and cessation of the catamenia in women ; all of these (and yet perhaps none of them singly and unsupported by the others) may be appealed to as evidence of a liability to diseases of the senile group generally ; and, if further corroborated by slight manifestations of actual disease, or of organic changes the result of disease, may form considerable elements in the diagnosis of a diathesis, as, for example, a tendency to hemorrhagic apoplexy. Or, again, certain transverse markings upon the teeth (quite distinct in character from those to be afterward noticed as syphilitic) ; curvatures, or other alterations in the form of the long bones, and a certain well-known conformation of the thorax, may indicate with the utmost precision disorders proper to the period of the first or of the second dentition, when rickety distortion, with or without bronchitis and other severe but not permanent conditions of disease interfering with the free ex^Dansion of the lungs, may have left an impress upon the bony skeleton. So, too, it may be remarked that the presence or absence of traces of past disease of the bones and joints, or of glandular enlargements and cicatrices in the neck, or of spinal disease, may, together with a certain conformation of chest, or indeed of the body generally, form part of a chain of circumstantial evidence, as it were, tending to prove, or to disprove, a liability to tubercular disease of the lungs. But what has chiefly to be rooted out of the mind of the ill- informed, or imperfectly trained, clinical student is the impres- sion that such conclusions are to be safely reached through mere phrases appealing largely to the imagination without minute and careful study of details. The popular, and to a certain extent the half-educated, medical mind is always look- ing for a pathognomonic sign, or a broad, striking, easy, gen- eralization from a few facts ; whereas it is only by ripened experience that we come to know gradually the real value of 16 THE PHYSIOGNOMY OF DISEASE. common and obvious, still more, of uncommon and not obvious, facts when seen in comb inatio7i, so as to form conjointly a basis for large inferences. Such a diagnosis, however, is often the result of the careful study of the physio(/nomic characteristics of individual patients. In beginning the study of this subject, it is impossible to overlook the importance of the weight and size of the body as a test of its physiological condition. Many diseases, perhaps indeed all diseases attended by fever, and many or most of the organic diseases of the viscera, whether febrile or not, are characteristically marked by a loss of weight, which often bears some sort of relation to the progress of the disease, especially in cases that end fatally. This tendency is the physical expression of a derangement of the entire textural nutrition of the body, one which, as a rule, becomes apparent externally, in the first instance, through the gradual wasting of the stores of fatty material in the subcutaneous layers and in the interstices of the muscles, omenta, orbits, etc. ; but which really carries as an ultimate result the wasting of every texture in the body — the bones, the fibrous tissues, and the nervous centres being (according to Chossat) the last to become appreciably altered in weight ; the brain, indeed, almost inappreciably, even in an animal starved to death. But in morbid inanition fas opposed to this physiological kind) there is usually not only deficient, but altered, tissue-formation ; so much so, that while fat dis- appears from all the usual situations in which it is normally stored up, fatty or oleo-albuminous molecules are formed in the microscopic elements of the Avasting textures generally, and chemical products, also, of decomposition of the nitrogenous tissues are found in excess in the blood, muscles, and glandular viscera. And this may take place (as in diabetes mellitus), when large quantities of actual nutritious matter of various kinds are passing through the organs of assimilation, and are even digested and assimilated, up to a certain point, with pre- ternatural activity. In such cases it has been said, with a certain amount of truth, that the body becomes autophagous, or self-devouring ; the muscles feed upon the integumentary tissues, the brain and nerves upon the muscles ; the new nourish- ment conveyed into the system, if any, being wasted and rapidly excreted, along with the effete matter of the wasting tissues. This state of morbid emaciation is most easily recog- nized in the living patient by gradual loss of weight, as well as by the external characters of shrinking and shrivelling of the soft tissues, in the order indicated above as a general rule. DIVERSITIES IN RELATIVE WEIGHT. 17 But loss of weight, as a personal and individual fact, can be exactly established only by repeated weighings of the same patient at intervals ; and in hospital wards this ought to be done on admission, and afterward every week or two, so as to obtain an accurate view of the progress of the case. In private practice, among men of the well-to-do classes, it is quite common, nowadays, to find that the habitual or physiological weight of the individual, and even the amount of variation in it in the midst of apparent good health, are well enough known to patients themselves, from actual weighings more or less fre- quently repeated ; and by availing ourselves of these spon- taneously provided data Ave are often able to form a tolerably clear conception of the morbid changes present at the time of first seeing the patient. But in other cases no such data exist ; and the " personal equation," so to speak, of weight has to be adjusted for the individual from more general statements, or from actual observations founded on averages. But this is by no means easy ; for the limits of variation in weight consistent with health, even in the same individual, have yet to be deter- mined ; and the extreme limits of difference in a number of individuals of like stature are notoriously so wude, even under strictly physiological conditions, as to render all averages in- applicable to the extremes. A vast series of observations by Dr. Hutchinson has, for many years past, been commonly ap- pealed to as affording the nearest approximation attainable to the common English standard of relative height and weight ; while a corresponding American standard has been furnished in the reports of the Surgeon-General at Washington. The Greek ideal of robust manhood in the well-known statue of the (so-called) " Dying Gladiator " has been made the basis of a mathematical calculation, by the late Dr. William Robertson, of Edinburgh, by which the statue, reduced to the proportions of a human figure, has been rendered (as it were) into exact terms of weight corresponding with every successive inch and half-inch of stature over five feet ; the normal elements of the human body in fixed proportions being taken as substituted for the marble. But all such calculations are, owing to the reasons stated above, of only a limited value to the clinical observer as furnishing a standa,rd of health. It appears, indeed, from more extended and recent anthropometric re- searches, that not only do the nationalities and races examined differ in their mean proportions, but that sex and age, social position and occupation, each in its degree, exercises a disturbing influence on the general or standard proportion, 2* 18 THE PHYSIOGNOMY OF DISEASE. which is capable of being expressed in figures ; so that among boys (say) of 15, girls of the same age, men of 20, artisans, gentlemen ; probably also for all manner of varying occupa- tions, certainly for English, Scotch, and Irishmen under like conditions, and (by inference) for all the many diversified races entering into the composition of these, a different standard of weight would have to be established as corresponding with every degree of stature existing in each of these categories.^ The almost infinite diversities which are thus shown to be con- cealed under a general average must necessarily lead to caution in the practical, or clinical, application of any of these formulas, without due consideration of the almost unknown limits of the diversities which in any individual instance may be consistent even with ideal good health ; and practical ex- perience teaches that a very considerable latitude is to be allowed in this respect, on either side of the mean. Perhaps the following condensed summary may be adoi)ted as an ap- proximation to the ordinary working rule applicable to most adult men -? A man of 5 feet should weigh from 8 to 9 stones. ' ■ - '■ i "4 ) " 5 ft. 3 ins. " 9 " 10 " ^ ^ " 5 ft. 6 ins. " 10 " 11 " " 5 ft. 9 ins. " 11 " 12 '' " G ft. " 12 " 14 " In applying these or any other relative numbers to an indi- vidual case it will be well to ascertain, as far as possible, the life-history of the actual 2:>atient in respect of height and weight proportion, if not in exact figures, at least in such terms as may be conventionally well enough understood for practical purposes. Supposing, for example, that the patient is a well- grown man, verging toward the " sere and yellow leaf," and in advancing age evidently tending to accumulate fat in the abdominal wall and elsewhere — Was he always "stout" (in the sense of his present condition), or was he, as a youth, " thin," or " slender," or " wiry," or " a light weight ? " All of these are expressions w^ell understood by most men as con- 1 One of the Tidilf^s (VI.) given in tlie Appendix to tliis chapter aijpearis to demou- Htrato from numerical data, that the food of infants under a year old lias a most marked influence on their condition and bodily weight, and possibly even on their stature. - The data in the text are purposely given so as not to imi)ly too close or too absolute an ai)i)roximation to an ideal standard, lait to funnuliite what may be easily retained in the memory f(jr every-day use. At the end of this chapter will lie found a n\imber of more ajfparently ]»recise calculations (including those of Dr. JIutchinson above men- tioned) ; the differences among these being significant of the latitude that must be allowed in an individual case, as well as some of the more calculable elemcuts in the variations above referred to. CORPULENCE. 19 veying easily appreciable relations of bodily conformation, and the last of them might even lead to more exact statements tending to determine the precise time of life when the sense of an increasing burden of flesh became manifest as a subjective fact. In the growing period of the body it is quite common to say of persons of slender habit, that they '*' shot up very fast" — i. e., that the increase in height did not carry corre- sponding breadth along with it in boyhood ; and this expres- sion, or something like it, is often used by mothers as indicat- ing a fear or misgiving that the phthisical tendency, either as a diathesis, or even as an actual disease, may have existed or been manifested at an early period of life. " Wiry," again, is generally open to a different interpretation ; it corresponds in a man, to what in a woman would be called (but not, of course, by herself or her friends) " scraggy " or " raw-boned ; " viz., a physical conformation in which bone and muscle pre- dominate, and the whole organization indicates a robust and active rather than a graceful or refined personal presence ; but, nevertheless, a bodily organization perfectly sound in essentials and eminently fit, from its very hardness and angu- larity, to do rough work in the battle of life. " Thin," or " slender," in a man, perhaj^s conveys the trace of an impu- tation of physical inferiority ; or, on the other hand, these ex- pressions may be perfectly indifferent as regards previous health or disease. The physical opposites of these bodily states, within the limits of health, are usually conveyed by the expressions " lusty," or " stout," or " in good condition," and a little good-humored allusion, half in joke, will often elicit most important facts for the physician ; indeed, begin- ners would do well to study the facetious vocabulary of Prince Hal, as applied to that great impersonation of vigorous and humorous rotundity — Falstaff, in the pages of Shakespeare.^ In women, and especially in those who have still reason to be careful about appearances, it is necessary to take care not to give offence by a too abrupt or coarsely worded question ; but with a little tact there is no real difficulty in getting at the facts in a round-about way, and even without using the sickly French slang of " embonpoint," which is supposed by some to 1 "King Hem-y IV.," Part I. — The converse of the character of that lusty knight, who might be supposed to he the original of the proverb, "Laugh and grow fat," will be found in Ctesar's remark on Cassius as a probable conspirator, and "dangerous," on account of his "lean and hungry look," his much thought and reading; his keen penetration "quite through the deeds of men ; " and his contempt of personal gratifica- tion and amusement. A perfect type of what would be styled in old medical language the "bilious," or rather "atrabilious," or "melancholic temperament."— See "Julius Caesar," Act I., Scene 2. 20 THE PHYSIOGNOMY OF DISEASE. be specially polite language as applied to ladies of a somewhat too large and substantial physique. But in all these inquiries and observations it is to be remarked that the experience of years, and the critical appreciation of the human form under a great variety of conditions, normal and abnormal, give to the physician in many cases a power akin to that of the artist, incommunicable by words ; an instinct of divination, so to speak, by which the true character and the history of the organism may be read in the external features and physical characteristics; and this, not only as to health and disease, but as to all the leading elements of character.^ There is one remark that will not perhaps quite readily occur to the superficial observer, but which is, nevertheless, of the widest possible application to the subject of body-Aveight, and of the greatest significance in respect to the physiognomy of disease. It is natural, perhaps inevitable, to think of great and small body-weight as being really opposed or contrasted conditions, just as we think of giants and dwarfs as opposed or contrasted in respect of stature and general bulk. But this is a false, or at least a misleading analogy ; for while a son of Anak may be in every way as healthy and as well pro- portioned as a General Tom Thumb, it is impossible to look upon excessive any more than defective body-weight, per se, as a mere question of big or little. Up to a certain point, in- deed, and within the limits of strict physiological health, the increase of bulk may be a mere question of degree ; e. g., a man of medium stature may be 140 pounds in weight, or he may be 180, or even, perhaps, 200 pounds ; if the projjortion of all the more important or essential bodily parts is fairly preserved — e. g., of the muscles and ligaments to the bones, of the viscera of the chest and abdomen to the external struct- ure, and of the cavities to the viscera — there will not be neces- sarily, at least, any appreciable impairment of function, or any disease. But the tendency of extremes in both directions is very apt to be toward impaired function, and, therefore, toward actual or proximate structural disease. And in the case of excessive corpulence, still more than that of excessive emaciation, it may be said that the morbid tendency, once im- ' It is, however, liere especially, because of the almost infinite complexity of the Iihciioineiia which have to l»o considorerl, tliat the tjreatest scope is found for errors or iriia^iiiatioris arising from the (h^sin; to formulate prematurely the mere impressions of ail in. 70), as probably characteristic in some degree of phthisical emaciation, and as being found most frequently "in incipient phthisis over the seat of the irritation" — i.e., on the side first affected and in the sui)ra-clavicular region. Ac- cording to Dr. Tait, the sign attends especially the softening stage of tubercle. "After each stroke of the ends of the fingers" (say the first discoverers of this sign) "a number of little tumors appeared, answering exactly to the number and situation of the points of the fingers, when they had struck the integuments of the chest. These having continued visible for a few moments, subsided, but could be again made to appear on repeating the percussion." [My observations, in very numerous instances, lead me to concur with the original rlcscrijition here given more closely than with the details of fact and of procedure ill Dr. Lawson Tait's paper. In i)arti(ular, I have fimnd that the "little tumors" of Drs. Graves and Stokes, which are undoubtedly tlie more im|)ortant part of myoidema, are produced more easily, and with far less risk of fallacy, when the percussion is made, not over a voluntary muscle at all, but over the anterior co.stal cartilages. The name th<'r(!fore seems, in a certain sense, a misnomer, if it is intended thereby to suggest that the iiintraction of the fibrilbe of voluntary muscle has anything to do with tlie more dis- tinctive iihenomeiia. The " little tumors" are (juite evidently due to a temporary con- traction of muscular fibres in the skin itself, similar in kind to those of the dartos on pinching the scrotum. I believe the jduuiomenon, thus iuterjireted, to have some, but by no means a pathognomonic, significance. — W. T. G.] ANEMIA. 25 the gravest import, as tending to reveal disease of the meninges of the brain, even should the symptoms otherwise be obscure or wanting ; still more, if these indications are accompanied by peculiarities of expression, or abnormal movements of the eyes (strabismus, nystagmus) or of the pupils ; or by the phenomenon described by Trousseau as the " tache cerebrale," and considered by him to denote fever with a cerebral or meningeal lesion/ A condition frequently, but not necessarily, associated with the phthisical or morbidly emaciated habit, is ancemia; a term which has been variously defined, but which may be taken as corresponding in general not so much with diminu- tion in the absolute quantity of the blood as with depreciation of its quality : a lower specific gravity of the serum, a more or less considerable fall in the proportion of the blood-corpuscles, and of course of the coloring matter. Physiognomically con- sidered, anaemia is recognized chiefly or exclusively by this last character ; and the most marked examples of it are those in which emaciation, though perhaps present more or less, is not extreme. If, indeed, the blood is simply reduced in quantity as a part of the general emaciation, but remains not greatly out of proportion to the other tissues (as in many cases of phthisical emaciation), the characters of ansemia will not be at all strik- ingly present. The lips will remain well colored, and the mucous membrane may even be morbidly congested in such a condition. But when, along with only a moderate reduction in the amount of the solid soft tissues, and without any circum- stance tending to the local determination of blood, there is a great reduction in the quality of the latter, the consequences as regards the appearance of the patient are very striking. There is, in the first place, an extremely pallid hue of the whole sur- face, and especially of the face ; lips not quite so pale as the rest of the countenance, but entirely devoid of their natural rosy hue ; the conjunctivae of the eyelids similarly pale ; the ocular conjunctivae bluish, from the shining through of the choroid ; and all these characteristics brought out the more remarkably in dark complexions, inasmuch as the tints wdiich depend not on blood but on pigment may be unchanged. Thus the skin may be as nearly as pale as that of a corpse, and yet 1 On drawing the back of the nail or the blunt end of a pencil along the skin, we find, in the healthy subject, that a momentary whiteness of the part is followed after a time by a distinct red streak. But in certain states this redness is much more easily produced, and is likewise very much more intense and persistent ; it is to this excessive redness that the term tache cerebrale is applied, from its being frequently observed in cases of acute meningitis. Biit it is now quite certain that it may be found equally in cases of enteric fever, and in many other diseased conditions. 3 26 THE PHYSIOGKOMY OF DISEASE. there may be dark circles fchloasma) round the eyes or on the brow ; or the natural diffused pigment of the whole surface may be so exaggerated as to give to certain parts of it almost the appearance of the skin of a negro or mulatto (the so-called " bronzed skin " or "Addison's disease "). But in cases of anaemia, pure and simple, there is usually no special pigmentary change, and the whole external characteristics suggest merely an unduly watery or much impoverished blood. The skin is cool, and the tongue may be clean, though extremely pale ; there is often a little puffiness of the eyelids and dropsical swelling of the ankles ; it may be (as in Bright's disease) even general dropsy of the entire subcutaneous tissues. The mus- cles are flabby rather than much reduced in bulk ; the expres- sion is that of great languor, but not of suffering or of anxiety ; if the texture of the skin is fine and delicate, the blue veins may be seen below the surface, but reduced very much in volume as compared with the normal ; and in the veins of the neck there is found the well-known humming of the " anaemic murmur," or " bruit de diable." A special variety of this state of pure anaemia is chlorosis, in which greatly disordered or absolutely arrested menstruation in young girls is attended by all the circumstances above noted, often with a very remark- ably green tint of the complexion (as the name implies). In all these cases the blood, tested accurately by instruments devised for the purpose, shows a reduction in the amount of coloring matter, or of corpuscles, equal to one-third, one-half, or even more ; and in this way a physiognomic sign, which formerly could only be stated in general terms, can now be reduced to most accurate expression, and made subservient to exact observation as to the progress of disease or the results of treatment. (See Chapter IX.) When this anaemic condition is recognized, we must never rest satisfied in the investigation of the case till we have done our best to ascertain the probable cause. We inquire for the history of any hemorrhages or any of the less obvious forms of loss of blood described elsewhere (Chapter IX.). A similar deterioration may result from the chronic influence of the malarial fevers, for example, or from the recent occurrence of some acute illness from which the patient's system has not fully recovered. But too often such anaemia is only symptom- atic of the serious inroads of tubercular, syphilitic, malignant, or renal disease, and the investigation of the urine is so impor- tant in all apparently causeless forms of anaemia that it must never be neglected. Present or past suppuration of a chronic COLLAPSE. 27 character may likewise be responsible for the deterioration of the blood ; the extreme pallor and the wax-like appearance of patients suffering from the lardaceous (waxy or amyloid) degeneration of the viscera usually arise from such prolonged suppurations, but this disorder may also' be due to less obvious causes. The examination of the blood frequently guides to the diagnosis of leukaemia and to the investigation of the spleen ; or the general enlargement of the lymphatic glands may suggest the presence of Hodgkin's disease as the cause of the persistent ansemia. But after eliminating all these causes of the deterioration, we may still find ourselves in the presence of a simple progressive 2}e7micious amemia, the origin and pathology of which still remain obscure, while the tendency to death is very marked. The converse of ansemia, in medical language still current, is 2^lethora ; a condition which has had a great deal to answer for in medical pathology and treatment. But plethora, con- sidered merely as a morbid excess of blood, can hardly be said to hold its place among recognized pathological states at the present day ; fulness of blood, in other words, can scarcely be considered morbid, unless there is some other pathological change either as regards its quality or its distribution. The condition to which the name plethoric is usually applied is one in which there is stagnation of blood in the smaller veins of the surface, giving to it, especially in the face and nose, the rubicund and " port-winey " appearance suggestive of the days when two bottles of that luscious stimulant were regarded as a moderate allowance for a gentleman at an after-dinner sitting. This peculiarity of countenance, as well as the plethoric and well-fed condition generally, when occurring in persons (es- pecially males) past the middle term of life, particularly if associated with hereditary predisposition or with known habits of self-indulgence, has been regarded as among the notes of the gouty habit or diathesis, and also, along with a short and thick neck, as among the predispositions to apoplexy. There is a very remarkable condition of the blood and of the containing vessels, in one of its aspects allied to ansemia, in another to plethora — that, namely, which, attended with coldness of the surface and rapid depression of the powers of life, corresponds with the so-called " collapse " or " algide " stage of Asiatic cholera. In so far as this condition can be here dealt with, it may be regarded as one in which a highly concentrated blood encounters resistance in being driven through the capillaries ; the great mass of the blood, there- 28 THE PHYSIOGNOMY OF DISEASE. fore, tending to accumulate in the venous system, and producing congestion, and even ecchymosis, by rupture of the smaller veins. It has been shown by chemical analysis that the blood in this condition has lost a considerable proportion of its water and albumen, owing to the enormously rapid and cojoious discharges from the intestinal canal ; but the blood- corpuscles remain, for the most part, in the vessels. There is, therefore, a strange combination of shrivelling of most of the textures of the body from loss of fluid, and persistence of blood-color, altered, however, in the direction of lividity by deficient aeration. A person in this state has the skin, especially in the face and extremities, of quite cadaverous coldness, and oflen has the whole attitude and expression of a corpse ; the ends of the fingers are shrivelled, the features thin and j^inched, the nose and all the extremities livid in a high degree ; the conjunctivse are bloodshot and ecchymosed ; the eyes sunk in the orbits ; the tongue and breath cold ; the respiration and circulation almost inappreciable ; but there is no disappearance of the external fat, nor any true emaciation ; the breasts, accordingly, in w^omen, and the abdomen in cor- pulent men, remain well clothed with integument even after death. A condition more or less allied to this is seen in some cases of very acute peritonitis, tending rapidly to death, as in perforation of the boAvels, which, like cholera, may cause death by collapse in a few hours, though, of course, without the excessive evacuations above referred to. The traditional description of the so-called fades Hlppo- cratica is not very far removed in some of its details from the state of acute collapse as above described, and has been so often formulated in one shape or other by compilers, as con- veying the elements of a fatal prognosis, that it may be well to transcribe the words from the original source : " a sharp nose, hollow eyes, collajjscd temples ; the ears cold, contracted, and their lobes turned out; the skin about the forehead rough, distended, and parched ; the color of the whole face green, black, livid, or lead-colored." But the reader will do well to consult the other physiognomic details in Sec. 2-4 of the Prognostics of Hipj)ocrates (Dr. Adams's translation, vol. i. p. 236) for numerous vivid and picturesque touches which are now among the commonplaces of medical observation. And the description of the phthisical body by Aretseus is equally deserving of perusal, as a sample of accurate appreciation of detailed facts emanating from remote antiquity. The most important facts of the description referred to are as follows, ARET^US ON PHTHISIS. 29 but the whole chapter in the excellent translation of Dr. Adams well merits perusal : " Voice hoarse ; neck slightly bent, tender, not flexible, somewhat extended ; fingers slender, but joints thick ; of the bones alone the figure remains, for the fleshy parts are wasted ; the nails of the fingers crooked, their pulps are shrivelled and flat, for, owing to the loss of flesh, they retain neither their tension nor rotundity ; and owing to the same cause, the nails are bent, namely, because it is the compact flesh at their points which is intended as a support to them ; and the tension thereof is like that of the solids. Nose sharp, slender ; cheeks prominent and red; eyes hollow, brilliant, and glittering; swollen, pale, or livid in the countenance; the slender parts of the jaws rest on the teeth, as if smiling ; otherwise of a cadaverous aspect. So also in all other respects ; slender, without flesh ; the muscles of the arms imperceptible ; not a vestige of the mammge, the nipples only to be seen; one may not only count the ribs themselves, but also easily trace them to their terminations ; for even the articulations at the vertebrae are quite visible ; and their connections with the sternum are also manifest ; the intercostal spaces are hollow and rhomboidal, agreeably to the configuration of the bone; hypochondriac region lank and retracted ; the abdomen and flanks contiguous to the spine. Joints clearly developed, prominent, devoid of flesh, so also with the tibia, ischium, and humerus ; the spine of the vertebra, formerly hol- low, now protrudes, the muscles on either side being wasted ; the whole shoulder-blades apparent like the wings of birds. If in these cases disorder of the bowels supervene, they are in a hopeless state. But, if a favorable change takes place, symptoms the opposite of those fatal ones occur." — Aretceus.^ Causes and Syiwptoms of Chronic Dis- eases^ Book I., Chapter YIII., On Phthisis. In association with the various atrophic and ansemic states above referred to, we have to consider the physiognomic im- port of another much-abused word, around which, as around the words " diathesis " and " temperament," a great deal of very obscure pathology has been made to revolve. Cachexia, in its original and etymological sense (K.aK6~ and ^fn in fevers is to Ik; fo\iii(l in most cases of diabetes ni(!llitiis, in wliidi, with great emaciation and disorder of nutrition and of the urinary excretion, the surface often remains throughout harsiily dry and cool, the natural perspiration, even under severe exertion, being sus- pended. Generally speaking, a dry skin which does not very easily jierspire, and main- tains an ctiuable temperature, is tiie sign of a "wiry" frame and of good health. Cor- pulent persons, on the other hand, perspire easily. FEVER. 35 easily explained. Fevers depending on septic poisoning of the blood are recognized by the peculiar odor, as of putrefac- tion, which exhales from the body even at an early stage, before the cadaveric odor or the symptoms of approaching death have appeared; such cases may have a traumatic origin, or they may occur spontaneously, as in some instances of en- teric fever, of erysipelas, of dysentery, and of septic poisoning from infection. Fevers depending on abscess, or upon profuse suppuration in connection with mucous or serous surfaces, are often very specially characterized by the tendency to intense and repeated shiverings, which can be compared only to the commencing stage of the ague-fit. A like disposition to rigors sometimes follows the passing of a catheter or bougie into the bladder, and this without any appreciable injury done to the mucous membrane. All these phenomena may be fairly in- cluded in the range of physiognomic diagnosis ; the more pre- cise appreciation of temperature through the thermometer will come under consideration hereafter (see Chapter III.). In all fevers which continue for more than a brief period, the tongue becomes more or less coated with a white or yellow fur ; in the hectic of phthisis, however, and in some cases of enteric fever and of mild intermittent, the tongue remains surprisingly clean and natural. As the fever advances the fur increases, the papillae enlarge and become congested; the dorsum of the tongue becomes dry, usually first in the neighborhood of the raphe. At a still more advanced stage the tongue becomes dry all over, brown, and roasted-looking, while incrustations 0/ brown epithelial debris (sordes) gather upon the teeth, alveoli, and lips ; this condition is specially characteristic of typhus and similar fevers, typhoid pneumonia, and generally speaking of the more severe continued fevers from the middle of the second week onward ; it yields very gradually after the crisis, the fur being throw^n ofi" sometimes in patches, sometimes more evenly, and the natural moisture returning (see, also, Chapter XL). At the stage indicated by the phenomena just described, there has usually been more or less of mental dis- turbance, and the whole attitude and manner of the patient, as well as his words, indicate a wandering mind and semi- unconsciousness, or even an advance into coma, with great and increasing w^eakness ; the posture being in the more ex- treme cases absolutely prostrate on the back, with the mouth more or less open, the eyes half closed, and sometimes a film of dried mucus and lachrymal secretion on the conjunctivae; the pupils being often contracted so as to resemble pinholes, 36 THE PHYSIOGNOMY OF DISEASE. and insensible to light. When associated with profuse sweat- . ing, or, even apart from this, with cold extremities (the febrile heat remaining in the central parts of the body), the prognosis is as bad as it can well be in any fever. A very unfavorable sign is a starting or twitching movement of the tendons of the wrist (subsultus tendlnum), and tremor of the muscles gener- ally; still more unfavorable, if possible, are the movements of the hands described by Hippocrates, and reproduced by countless authorities with more or less conscious imitation for more tlian 2000 years under the name of Garpliologia, floccitatio, etc. : " When in acute fevers, pneumonia, phrenitis (acute de- lirium), or headache, the hands are waved before the face, hunting through empty space as if gathering bits of straw, picking the nap from the coverlet, or tearing chaff from the wall — all such symptoms are bad and deadly."^ The peculiar deadliness of such symptoms, it may be remarked, depends upon the fact of their indicating at once two apparently con- trasted states of the nervous centres and especially of the basal ganglia and mcsencephale, if not also of the medulla oblongata, viz., restlessness, with greatly lowered, if not lost, sensibility to external impressions ; unconsciousness, with dis- turbed excitomotor activity, and almost always with entire absence of real sleep (coma vigil); the movements are abso- lutely automatic, and yet they are continuous, being excited by some purely physical irritation of the motor centres arising apart altogether from consciousness, and acting feebly through the efferent nerves upon those groups of muscles especially which, in the normal condition, exhil)it the most highly differ- entiated and exquisitely combined movements under the influ- ence of the will. To the same order of phenomena belong the constant mutterings (typJioniania or typhoid'^' delirium) ; the wordless, and sometimes even voiceless, movements of articulation (innssitatio) observed in the later stages of many severe fevers, conveying to the mind of the observer merely 1 Prognoslifs, IV ; yVflaniH^H tniiislatini), vol. i. p. 2.'58. - It hIiouIiI ])(•■ ]iarti(-Mlnrl.y iciiiark(!(l, as nocc^ssary for the reconciliation of old and new tcrniH, tliat tin; word " typlioid " is not used \u'.ri' in tlu; H])('cial and limited sense given to it liy lionis an> coS a ^a Breast milk ....

CHAPTER II. EXAMINATION AND EEPORTING OF MEDICAL CASES. Case-taking. In examining cases brought under his notice, a physician is guided by the circumstances in which he finds the patient, and by his knowledge and experience of the condition with which he has to deal, and so, Avhile one case is approached in one way, another is dealt with in quite a different manner. No one method can actually be applied to all cases ; indeed, no one method could possibly be the best if used indiscrimi- nately. When a patient is gasping for breath and scarcely able to speak, we must reserve our questions for a few impor- tant points. When a patient is delirious, muddled, or obvi- ously unreliable, it is vain to try to procure from him a connected statement of his history and his sensations. If actually insensible, or in a fit, we dare not delay our examina- tion of his condition, so far as this can be ascertained, simply because we might prefer to await the arrival of information as to the previous history or the mode of attack ; such delay (even apart from all practical questions of treatment) might deprive us of the only opportunity of ascertaining the nature of the ailment. Nor would a physician exj)lore the family history of a person with scabies in the same way in which he would investigate this part of a phthisical case ; his questions directed to the patient with scabies on this matter Avould probably be limited to a few pointed inquiries to ascertain the infectious character of the eruption, from its presence in other members of the family. Usually we begin by incpiiring, more or less fully, what the patient feels to be wrong ; this serves to direct the first part of our physical exploration of the organs, and the mischief detected there often sends us back to inquire into the exact way in which the illness began, into the previous health, and the family history ; certain points thus ascertained may de- CASE-TAKING. 53 mand a renewed examination of the organs, or the exploration of other parts. In urgent cases we seize upon the severest symptoms, the dyspnoea or pain, for example, and try to get the greatest information attainable at the least cost to the patient, sparing him as much as possible the fatigue of questioning or of physical examination, according as the one or the other causes the greatest annoyance or danger, filling up the gaps as well as possible from the information supplied by the attendants. When there are obvious features of capital importance, such as jaundice, febrile eruptions, bronzing of the skin, j)ul- sating tumor in the neck, serious hemorrhages, profound anae- mia, and the like, we often begin with these facts, and having ascertained their origin, proceed in our inquiries to the other parts of the case and its earlier history. AVhen the illness is obscure, a more systematic examination of all the organs and functions of the body, and an equally careful inquiry into the personal and family history of the patient may be required to unravel the difficulties. In reporting cases, likewise, very different methods are pur- sued by the same physician, according to the varying peculi- arities and the different points of interest and importance in each case, and also according to the special object he has in view in making the record, whether for the purpose of treat- ment, of clinical teaching, or scientific research. The student in the medical wards, however, is not placed in exactly the same position. The cases assigned to him for reporting are usually selected by those in charge of the patients, and they seldom fail to warn the student when pro- longed physical examinations would be dangerous, or when special parts of the investigation must be omitted or passed over slightly. To the student, therefore, a more uniform plan can be recommended, and it is the more useful to him, as without some method to guide him he is apt to omit noticing various important features of the ailment. This may arise from forgetfulness, or from there being so many points which have to be investigated ; but the student is likewise apt to omit important parts of the inquiry from supposing that the indications of disease found by him in one part are sufficient to account for the whole illness ; having found, for example, the presence of albumen in the urine, and other evidence of renal disease, the beginner may never think of examining the heart, and may pass over a distinct loss of vision without 5* 54 EXAMINATION OF MEDICAL CASES. remark, supposing it to be due to a mere accidental coinci- dence. It is in the examination of the actual state of the patient (status prsesens) that the student chiefly requires the assist- ance of some method in his investigation of the various symptoms and physical signs. Many clinical teachers have forms drawn up to guide their students in the reporting of cases in their wards. As furnishing a memorandum, to re- fresh the memory, such forms are useful for beginners, but the slavish following of any such form is to be avoided. The examination of patients demands a review of the man- ner in which the various functions of the body are performed. It is usual to divide the manifestations of disorder into two classes— the " subjective " and the " objective." The " sub- jective" comprises those of which the patient himself is con- scious and for a knowledge of which we have to rely on his statements. The " objective " includes those of whose exist- ence the examiner has evidence from his own senses. The subjective manifestations of disease are those spoken of by many writers as " symptoms," the objective being named " signs," or sometimes *' physical signs." Some authorities, however, do not draw this distinction between " symptoms " and " signs ; " they use the word " symptom " as including both forms of evidence, and so they divide " symptoms," in their diagnosis, into (a) "subjective" and (b) "objective." It is well to keep clearly in view the distinction implied above, whichever meaning may be attached to the word "symptom," the more restricted meaning of which seems best for ordinary use. This distinction is, as a rule, clear and definite enough. A pain is a " symptom " (subjective) ; a bulging in the chest, to which it may be due, is a " sign " (objective) : giddiness is a "symptom" (subjective); the staggering resulting from it is a " sign " (objective). Frequently, how'ever, we find that no very accurate distinction is possible ; coughing is both a subjective and objective manifestation of disease, and so is vomiting ; bad forms of aneurismal pulsation may constitute the leading complaint of the patient, and may be perceived equally by him and by the i)liysician. Breathlessness is really a sense of the want of breath on the part of the patient, and so is purely " subjective ; " but in its extreme forms at least it is so obvious to any onlooker that it might be classed as " objective." Technically and strictly, the sense of breath- lessness and its attendant distress are " subjective ; " the rapid breathing, the effort in inspiration, or the posture assumed by SIGNS AND SYMPTOMS. 55 the patient during this breathlessness, may be classed as " objective." A preliminary division which is found convenient is to separate the " external " from the " internal " part of the examination, and it is safer always to begin with the external portion, as otherwise it is apt to be neglected. It can usually be dismissed rapidly, although there are some cases where this constitutes the main part of the examination. Unxler the external portion may be included those obvious features which go to form the '' physiognomy of disease," or refer to peculiarities in the conformation of the patient. The temperature of the body, although really an internal phe- nomenon, is usually judged of by the feeling of the skin, or by the application of a thermometer to the axilla ; it is thus included under this department. The conformation, weight, and muscular development, the apparent age as compared with the real age, the expression and complexion of the face, the presence of dropsy, the posture, and the like, come in here. An examination of the skin for eruptions, discolorations, scars, or tumors of any kind, and a survey of the limbs and joints, for any signs of disease, likewise fall to this portion of the investigation. Such facts as glandular enlargements may be stated in this connection. The internal examination deals Avith the functions of the various physiological systems, and on the whole the best method is to take up these systems one by one, stating whether they seem to be normal or in what points they deviate from healthy action. It is usually well, as recommended by the late Professor Sanders, to combine the anatomical with the physiological method, and to deal with the circulatory and res])iratory systems in sequence, as they both have their great central organs in the chest : and in the same way to keep in sequence the digestive and the genito-urinary systems as their central . organs are in the abdomen. We begin with the system which seems from the history or from the general aspect of the case to be the one most essentially affected, and we also, of course, consider it in much fuller detail. Hospital cases are usually so far prepared for the student by the previous record of the temperature and the preservation of the urine and expectoration for his in- spection. " If we find orthopnoea, general anasarca, and distended jugular veins, we begin with the circulatory system. 56 EXAMINATION OF MEDICAL CASES. " If we find iDurulent expectoration, emaciation, and clubbed finger-ends, we begin with the respiratory system. " If we find albuminous urine and pale puffy countenance, we begin with the urinary system. " If we find jaundice and protuberant abdomen, we begin with the digestive system. " If we find paralysis or convulsive twitches, we begin with the nervous system, and so forth." (Sir William Koberts.) These anatomical and physiological divisions could never, however, preserve us from making serious omissions in our reports, unless each detail in each system were investigated with an absurd and, indeed, a reprehensible completeness. The manifestations of disorder in the various systems often appear in the most unexpected quarters. These points can only be learned by a varied experience of morbid conditions, such as the beginner cannot be expected to possess. The de- tailed description of the symptoms dealt with in the various chapters of this book are intended to supply, to some extent, from the experience of others, the want thus felt by a beginner, so that Avhen he comes upon any of these symptoms he may know how to pursue the investigation in its various ramifica- tions, and to estimate to some extent the bearing of the facts on the diagnosis. As an indication of the points to be investigated under each heading, and the order in which the inquiry may be taken up, the following tabular statement is appended. It is slightly modified, for the present purpose, from the form used by Professor Leech, of Owen's College, Manchester : NAME — SEX — AGE — ADDRESS — OCCUPATION — DATE OF ADMISSION — PHYSICIAN — REPORTER OF CASE.

The history of the illness under observation should, as a rule be taken separately from the record of the general previous health of the patient. We begin by seeking to know what symptom, or combination of symptoms, or what circumstance has brought the patient into the hospital, or made him seek medical advice. The points regarded by the person himself as important are thus obtained, and should always be recorded at the beginning of our reports, even although they may not seem to us the most essential features of the illness. The subsequent course of the case has often much light thrown upon it by this record of these indications, for the patient may feel tlie importance of certain things which may be over- shadowed in our minds by considerations based on our theo- retical views. Taking these leading comj^laints as our basis, we try to dis- cover the date at which they appeared, the order and sequence of the symptoms, and the relative severity of the different parts of the iUness at different times, and particularly the date at which the disease laid the person aside from work and confined him to the house, or to his bed, as the case may be. Having traced the date and origin of the present complaints, w^e seek to ascertain if they arose in the midst of health, or if they sprang out of some previous illness or general derange- ment. If it appears that the patient regards the present ailment as definitely originating from some other illness, or if from the known facts of disease this relationship seems prob- able to ourselves, we begin our history of the present illness with an account of the earlier one out of which it has seemed to spring. But if the present illness cannot be well defined by a date of previous health, or if the history is entangled in a long story of former disease or general delicacy, it usually HISTORY OF THE PATIENT. 61 conduces to simplicity to begin by taking the history of the present aggravation of the condition separately, and then to include the former part of the illness in the account of the previous health of the patient. For example, if we find that dyspnoea, dropsy, etc., constitute the chief complaints of the patient, if these have existed for two or three months, and seem to date from a second attack of rheumatic fever, six months ago, we may begin with this second attack of rheuma- tism ; we trace the sequence of events from it, and reserve a detailed account of the first rheumatic attack, and any former illness, for the other part of the case which deals with the previous history of the patient. But if we find a serious haemoptysis, or a violent pain in the chest, or severe headache and vomiting to form the obvious and urgent comj^laint of a patient on admission, we deal first with the origin and course of these, even although it may be certain that the patient has long been the victim of chronic lung disease. Having traced the history of these urgent features of his complaint, we can go back and try to unravel the tangled web of chronic ill health in all its various manifestations. In the case of children, and especially of young children, we may often save time by ascertaining from the mother the point in the child's age up to which he was regarded as healthy. We may note in passing whether the child was suckled, or how he was fed, when he was weaned, when dentition began, and when he was able to walk. From this period of health we trace all the illnesses onward, up to the present, even although there may not be much connection between them. If, again, the child has been delicate from birth, or troubled with many recurring illnesses from the beginning, it is equally important to procure a connected history of all these, so as to judge of the child's prospects in the present attack of whatever kind this may be. In procuring the history of an illness from the patients or their friends, we should try to get the facts as known or observed by themselves, rather than mere names or theoretical conceptions, such as "inflammation," " brain fever," and the like. Calling an illness "rheumatism," for example, may tend to mislead us in the history of cases which really depend on spinal meningitis or locomotor ataxy. We must try to learn from the patient or his friends, in such a case, what evidence there was of the so-called rheumatic attack, whether it confined the patient to bed, whether it was associated with distinct swelling of the joints, wdiere the pain was localized, 6 62 EXAMINATION OF MEDICAL CASES. whether there was feverishness, and so forth. The story of any so-called inflammation of the chest or lung must likewise be recorded, with such additional information as can be ob- tained, and in such cases the duration as well as the symptoms should be stated; this may tend to confirm or to throw doubt on the name given. Sometimes, however, when the name of the disease is given with some precision, and stated on the authority of some medical man, or in connection with some hospital, we may accept the name of the disease, adding in our notes the authority on which we do so. In following up the sequence of symptoms we also aim at representing in our report the facts of the illness as actually exi)erienced and complained of by the patient, apart from all theoretical views; some j^atients are very fond of importing these into their narrative. The reality or severity of certain symptoms may often be usefully indicated by stating special facts ; for example, in a case of swelling of the belly, that the skirts had to be widened, or that the trowsers could not be buttoned ; or in a case of weakness, that the person could not walk across the floor without assistance ; or in the case of pain, that the patient could get no sleep, or that he screamed out, or fainted in connection with it. Details like these guide our estimate of the value of the history as derived from the patient. We must, likewise, make use of our own knowledge to check the patient's history, particularly in putting sj^ecial questions to make sure of the real facts when the account seems im- probable or incredible. We may also, after getting the history from the jiatient, inquire as to whether certain sym2)toms were not present, as he may have forgotten them, but we must, if possible, avoid j^utting ideas into our patients' miuds; leading- questions must be sparingly used, or at least reserved for the end of the interrogation, and in particular to bring out nega- tive points in the case with clearness and precision. The history of the previous health should be, in part, of a general kind, such as patients can readily supply ; the dates and durations of previous illnesses should, as a rule, be speci- fied, as well as the names of the diseases ; the general state of the strength, especially as regards the ability to work, and the date of any deterioration in this respect must likewise be noted. But in addition to this general sketch we must often put special questions as to special points, which the patient might otherwise overlook. Thus, in cases of heart disease, we always inquire about rheumatism ; the indications of this, especially in childhood, are often so slight that they might SOCIAL HISTOKY: HABITS. 63 easily be missed without some special inquiry. In cases of spinal paralysis, aneurism, and some other affections, we must inquire for any strain or injury, and we note its date and the exact manner in which it happened. We must often, indeed, go back upon the history of our patients, especially as regards this earlier portion of it, after the examination of the case in various ways has guided us so far to the diagnosis. Some- times, moreover, as described in the section on ", Family His- tory" (see p. 68), we must search about in aur questions for diseases allied to the one suspected to exist, using popular names likely to be known by the patient or his friends. The inquiry as to previous venereal diseases is often impor- tant, but must be approached with delicacy particularly in the case of women, and especially when dealing with those Avho are young and apparently respectable. We may often gain some information as to syphilis in an indirect way, by inquir- ing for a history of sore throat, skin eruptions, nodes, noc- turnal pains, and falling out of the hair ; or, in the case of those who have had children, whether any of these were born dead, whether there had been any miscarriages, whether the children born alive had eruptions on their buttocks, snuffles, or the like. We can seldom place much reliance on the mere denial of syphilis, and it should be remembered that men frequently refuse to admit having had syphilis, although they confess readily enough to having had gonorrhoea frequently : it is apparently the question of constitutional taint and not of morality which determines such denials : with tact in ap- proaching the subject we can often obtain the history and date of infection. The history of gonorrhcea is important in certain arthritic affections, and particularly in cases of uri- nary irritation, as when stricture follows it, the bladder and kidneys are often involved. Syphilis has to be considered in the history of a multitude of diseases — skin diseases, nervous affections of various kinds, disease of the liver, amyloid degen- eration of the liver and kidneys, aneurism, and other forms of disease of the bloodvessels, laryngeal ulceration, etc. Social History: Habits. — Certain points not of a purely medical character are usually inquired into, in addition to the bare facts as to age, occupation, residence, marriage, etc., wdiich are taken in all cases for the routine purpoi^es of the hospital records ; special points must often be searched out. The age often suggests a comparison between the alleged and the apparent age of the patient. The occupation may have to be scrutinized as to the special 64 EXAMINATION OF MEDICAL CASES. peculiarities of the employment, and the exposure to evil influences known to beset certain trades ; former occupations sometimes explain certain ailments, and this is important in connection with those who have been discharged from the army and are now engaged in other pursuits. Occupations which are apt to injure the health or to favor the devel- opment of disease can onl}- he roughly indicated here. Soldiers and sailors are specially liable to aneurism. Hammermen and others using their arms violently, are frequently the victims of aortic valvu- lar disease, apparently owing to the strain on the great vessels. Publi- cans and others having to do with the manufacture and sale of alcohol are liable to disease of the liver, kidneys, and nervous system: this arises partly from the injurious influence of the vapors, particularly in badly ventilated places where they may work, hut chiefly from the constant exposure to temptations to excess which many cannot resist. Some of those employed as commercial travellers are exposed to similar dangers. Butchers have been supposed to be injuriously influenced by their business, and have been regarded as specially liable to apo- plectic attacks. Coal miners are subjected to the influences of cold and damp in their work, which often implies constrained postures, and so they are found to be liable to sciatica and other more distinct forms of rheumatic disease. Agricultural laborers, fishermen, and others much exposed are also liable to chronic rheumatism. The inhalation of dust in various forms often gives rise to disease of the lungs, and this is specially the case when the ventilation is bad. On this account miners suflfer from a special form of lung disease from the coal dust and the soot resulting from blasting, etc. Knife-grinders, stone- masons, and potters are all liable to peculiar forms of pulmonary con- sumption. Some factory workers owe their liability to lung disease partly to dust and partly to confinement in close rooms. Those whose work is among horses and cattle may more readily contract glanders, farcy, and other animal poisons ; the}' are also more exposed to anthrax or malignant pustule : but workers in hides, horsehair, etc, are also affected at times b}' this formidable disease. The influence of metallic jjoisons is shown in those who work with mercury in " silverizing " mirrors. Those who make white lead are specially subject to the inju- rious influence of this metal ; but painters, glass-workers, potters, and at times plumbers, dyers, and others brought habitually into contact with lead are frequently affected. It should be borne in mind, how- ever, that lead poisoning is often due to contamination of the water supply and other articles of food and drink quite apart from the occu- pation of those aflected. Sedentary or studious occupations are apt to be specially injurious to adolescents of both sexes, and the effect is often intensified by this change in their occupation coinciding with a change of residence to a large town and living in lodgings for the first time. In such cases the appetite and dige^^tion are apt to fail, and any tendency to lung disease is readily developed. Sedentary occupations in older people favor indigestion, liver disorders, piles, etc. Girls exposed to prolonged standing, as in serving at counters, or to con- tinuous exertion with their feet in working sewing machines, often suffer in their general health and in their pelvic organs. Firemen on USE OF ALCOHOLIC STIMULANTS. 65 board of steamers are apt to have disorders of the kidneys, no doubt from the profuse sweating to which they are exposed. Bright's disease seems liable to occur in those exposed by their occupation to habitual cold and wet. Mental strain, so notable in some forms of com.mercial activity, is likewise supposed to lead to Bright's disease ; of course, the same influence at business, literary work, or school may lead to various disorders and diseases of the brain. On the other hand, the want of due work and occupation for body and mind is apt to favor hysteria, hypochondriasis, and a multitude of nervous disorders. The residence may raise questions as to the healthiness of the locality, its freedom from certain diseases and its exposure to others; the accommodation in the particular house may also have to be investigated, as regards its cubic space, its water supply, drainage, etc. ; former residences, exposure to malarious influences, to tropical climates, etc., have often to be inquired for, and the results must in many cases be recorded even when they are negative. The kind of food habitually used often supplies very impor- tant light as to certain diseases ; the use of tea in excess, especially if to the exclusion of milk, vegetables, potatoes, etc., often explains scorbutic, nervous, and dyspeptic disorders. The excessive use of tobacco is suggested in cases of cardiac palpitation or pseudo-angina pectoris, dyspepsia, dimness of vision, quasi-paralytic disorders, and other forms of nervous disturbance. The use of alcoholic stimulants must be inquired into in cases of liver disease, and so-called " bilious attacks," renal affections, dyspeptic complaints, convulsive attacks, par- ticularly when affecting male adults, and in all diseases char- acterized by delirium, with or without much fever ; the history of any previous intemperance often explains the high delirium present in acute illnesses, and has great importance in the prognosis and the treatment. The form of alcohol used, whether wine, beer, or spirits, is sometimes a matter of impor- tance ; even the exact variety of spirit used is sometimes a point of interest ; the use of undiluted spirits on an empty stomach seems to be very specially injurious ; we must like- wise ascertain whether a somew^hat excessive use of alcohol was of daily occurrence, or whether the excess was only during an occasional outbreak in the course of wrecks or months. The regular use of other stimulants or sedatives, especially opium, chloral, ether, and chloroform, must sometimes be in- quired into. The fact of marriage, its date, and the number of children born alive and dead must also be recorded, particularly in the case of w^omen, and in their case the number and date of mis- 6* 6^ EXAMINATION" OF MEDICAL CASES. carriages or abortions should also be noted in some part of the report. The practice of masturbation is to be inquired for with great caution, as we must avoid suggesting the idea of evil to those whose minds are free from any such notions ; but in certain cases of epileptic seizures, in certain forms of cardiac palpitation in boys, and in some cases of nervous prostration and spermatorrhoea the questions must be put with clearness in the interest of the patients, for their warning, quite as much as for the benefit of the diagnosis. Excessive venereal indulgence, whether within the marriage state or not, is often responsible for nervous disorders, spinal paralysis, locomotor ataxy, and other less definite forms of disease. These effects are more common in the male than in the female. Family History. The importance of family history in throwing light on the tendency to special diseases is well shown in life insurance studies. This inquiry embraces a note of the age of the pa- rents and of the brothers and sisters of the patient, and of their state of health, if alive ; of the ages at which any such relatives may have died, the nature of the illnesses they have had, and the diseases which caused their death. Inquiries as to other relatives are occasionally important, especially when the number of brothers and sisters is small, or the information regarding them obscure ; the grandparents, and the uncles and aunts of the patient, on both sides, are the most important in this respect. In going beyond these to half-brothers or sis- ters, to nephews and nieces, to cousins, or even to the children of the patient, we necessarily introduce complications from marriage ; these, however, may sometimes be allowed for in summing up the inquiry. Now all this information can seldom be obtained with any feeling of accuracy, and in hospital practice the deficiencies are so enormous as to discourage the student, and perhaps to give him an erroneous view of the value of this branch of the inquiry. We should begin by getting the bare facts as to the size of the fiimily, the ages of those living, and the diseases and ages of those who have died. In some cases, where we can interrogate the mothers of children, with suspected syphilis for example, we should also try to obtain the number and dates of the miscarriages and stillbirths, ascertaining whether these occurred before or after the birth of the child under FAMILY HISTORY. 67 consideration. The further prosecution of the inquiry must turn upon the facts thus elicited, and upon the other facts discovered in the investigation of the illness. Hence we often revert to the family history at the end of the inquiry, to bring out information on special points as to the health or history of the living or the dead. When the causes of death alleged are doubtful or unsatisfactory, Ave may sometimes judge for ourselves from the facts of the illness supplied by our inform- ants. In particular, we must receive with great reserve the deaths set down to "teething," "change of life," "childbirth," " cold," " inflammation," etc. Many deaths are set down to childbirth or change of life, although really due to phthisis. Consumption often leads to disorders of the menstruation, or its suppression at an early age ; and childbirth is frequently followed by a very rapid progress of the same disease which may not, up to this point, have been clearly recognized, or at least admitted. Regard should be had to the age at which such a death occurred, how long the confinement had been survived, how long the weakness had lasted, and whether it was associated with cough, spitting of blood, or other suspicious symptoms. In these doubtful cases, inquiry as to the collateral branches of the family is important — e. g., if a patient's mother is reported to have died from a cause in doubt we may search with advantage into the history of the maternal uncles and aunts. " Inflammation of the lung" and " pleurisy" must be scrutinized in the same way, especially if other deaths occurred from phthisis or pulmonary affections in the same family ; if either pleurisy or pneumonia proved fatal after a prolonged illness, we may suspect that these were allied to phthisis, or that some such tendency existed in the constitution of the victim. The name of " bronchitis" also covers many deaths from phthisis : the age of the subject, the duration of the ill- ness, and the occurrence of lividity, dropsy, etc., may some- times guide us. "Worm fever," "intermittent fever," "the dregs of the measles," and some other terms of this kind are often merely popular names for tubercular disease. Sudden deaths ascribed to apoplexy are to be investigated as to whether the death was almost instantaneous or whether the illness lasted at least some hours ; in the former case cardiac or aneurismal disease is more probable than apoplexy ; apoplectic attacks in early manhood, with one-sided paralysis, are to be suspected as due to syphilitic, cardiac, or renal disease. In fact, the name of the disease must be regarded, unless sub- stantiated by good evidence, as of only little account ; all the 68 EXAMINATION OF MEDICAL CASES. knowledge we possess of the nature of diseases and their rela- tive frequency at particular ages, and in particular countries, must l)e brought to bear on the scrutiny, and some familiarity with the names of diseases in common use among the poor is also of much value in hospital inquiries. In inquiring into the illnesses which the members of a family may have had, it is desirable to suggest various dis- eases allied to the one known or suspected to exist in the patient, using for this purpose various names, so as to meet the limited knowledge of our informants, and also to refresh their memories. Thus in regard to scrofulous diseases, we ask for swollen glands or " waxen kernels," or runnings in the neck, disease of the spine and other bones, bad joints, white swell- ings or " incomes," as they are termed in Scotland, chronic ulceration of the intestines, and chronic peritonitis, disease of the glands of the bowels, water in the head, consumption of the lungs, or decline, or weakness of the chest with spitting of blood, and so on ; we may in this way get at the facts when a more general question fails. It is wise also in most cases to avoid disagreeable Avords, such as scrofula, in the first instance at least, as many people are so annoyed at the suggestion of such affections being supposed to exist in their family that they are shy of giving any detailed information. In inquir- ing for a family history of cancer we should likewise be chary of mentioning this dreaded name, at least if our patient's dis- ease is only of doubtful malignancy, trying rather to get our informants to volunteer statements on the subject, and search- ing for the information wanted under the names of growths, tumors in the breast or elsewhere, disease of the liver, stomach, or womb, with wasting, jaundice, dropsy, floodings, etc. We must further bear in mind, in these inquiries, the varia- tions of allied diseases which appear in different members of the family, and in different generations ; by asking for such by name we often refresh the memory of our informants. Heart disease, rheumatism, chorea, psoriasis, and some other cutaneous affections, perhaps also renal concretions, and em- physematous bronchitis, appear to replace each other in different members of the sanie family. Thus, a patient may be said to have inherited heart disease from his having in- herited rheumatism, leading, as it so often does, to an ^affection of the heart ; but another member of the same family may have had heart disease transmitted to him Avithout any overt rheumatism in his own history. The neurotic group includes the various forms of neuralgia, hypochondriasis, hysteria, in- FAMILY HISTORY. 69 sanity, epilepsy, and chorea ; apoplexy and hemiplegia are included by some fperphaps doubtfully) in this group, their hereditary character seems rather to be associated with vas- cular disorders. Not unfrequently the patient seems to inherit an unstable nervous system, predisposing to all sorts of nervous disturbance rather than leading to any one form of disease. Certain rare forms of paralysis, as wasting palsy and pseudo-hypertrophic muscular paralysis, tend to occur in various members of the same family. Sometimes a disease occurs in various members of a family without any inherit- ance being traceable {e.g., so-called "hereditary ataxy" or "Friedreich's disease")- Gout, disease of the liver, con- tracted kidney, renal calculus or gravel, and angina pectoris form another allied group. These have also some affinity with the disorders connected with arterial degenerations, and so may lead to aneurismal disease or to apoplectic attacks. Certain forms of glycosuria, particularly in those who are somewhat stout and beyond middle life, tend to occur in patients of this class. Syphilis, which has, of course, marked hereditary characters, assumes such a multitude of forms as to preclude enumeration, but the tendency is for such syphilitic diseases to die out in the course of time from early death or sterility. Abortions, stillbirths, early deaths in infancy asso- ciated with cutaneous eruptions on the buttocks, snuffles, and wasting, are important in many family histories ; nervous deafness, opacities of the cornea, notched teeth, epilepsy and imbecility are occasional manifestations of the same disorder in those children in the family who survive ; in adult subjects who have acquired syphilis we must either put the question of infection directly or investigate their symptoms and condition when the question of syphilis is important in the family his- tory we are studying. The group of scrofulous and tuber- cular diseases has been already referred to. Diabetes has often a distinct hereditary origin, and at times it is also mixed up with a family history of tubercular tendencies. Although family history is chiefly useful in determining the tendency to certain chronic and constitutional affections, or to premature decay of the individual, or of certain of his organs, we find, likewise, a tendency in some families to acute diseases — enteric fever, for example, and even to certain de- grees of severity or to special complications — as intestinal hemorrhage — and this may guide us at times, especially in prognosis. In diphtheria also we have an illustration of an acute infectious disease affecting special families in various 70 EXAMINATION OF MEDICAL CASES. branches and at various times and places to a striking extent. Such cases are very instructive, in view of the recent doctrine of phthisis being due to a specific organism — so far resem- bling the organisms of the infectious fevers — and in view of the admittedly hereditary character of this complaint. It is sometimes quite evident from which of the parents a patient has acquired his morbid tendency, and in some insur- ance reports information is sought as to whether the proposer resembles the male or the female side of the house in his gen- eral conformation, so as to judge of his j^redisposition to diseases which may exist on the one side and not on the other. No doubt there is some guidance to be obtained here when the whole facts are well known to the physician himself, but otherwise he cannot- place much reliance on mere statements. Sometimes two perfectly distinct forms of disease are found in the same family, the father contributing one tendency and the mother the other. TRANSMISSION OF TWO FORMS OF DISEASE.

Eldest sister; pains in knees and shoulders, but no serious ill- ness. Other five brothers and sisters ; none of them rheumatic, but some of them affected or threatened, more or less distinctly, with con- sumption. The healthy condition of one parent may indeed tend to neutralize the morl)id proclivities acquired from the other; and, on the other hand, similar morbid tendencies in the families of both parents seem to tell with special severity on their offspring. It is probably in this way that the injurious influences of consanguineous marriages come out. In remote islands with but few families, for example, repeated inter- marriages seem to favor imbecility in the children ; and deaf- FAMILY HISTORY. 71 mutism has at times, likewise, appeared to be due to similar causes. In other cases, however, two or more deaf-mutes may be born into a family without any such cause or without any hereditary history being known. The question as to which parent is the more potent in transmitting morbid tendencies cannot as yet be answered satisfactorily. In the case of consumption it would seem, from insurance statistics, that a consumptive mother is more likely to transmit this disease than a consumptive father ; and when we have the history of a consumptive mother and of one brother or sister being affected, this fact is usually re- garded as adding greatly to tlie risk. Probably in other diseases the transmission by the mother is more potent also, and in the case of the "hemorrhagic diathesis" the disease is almost invariably transmitted through the female line : this is all the more curious inasmuch as the mothers, and indeed all their sex, almost invariably escape. This disease affords an illustration of hereditary transmission without either of the parents being affected; but one or other of the maternal uncles may be "bleeders," as they are called — even, however, when they marry and have children their children are not affected. TRANSMISSION TO MALES IN FEMALE LINE. Family history, showing the occurrence of the hemorrhagic diathe- sis in three successive generations.

In another large family of cousins, males and females, by another maternal aunt, none affected. 72 EXAMIKATION OF MEDICAL CASES. More misleading still are the facts of atavism ; in this case the whole of the generation of which the parents are members escape, but inquiry into the history of the grandparents or the granduncles or aunts of the patient may reveal a strong family predisposition to special diseases. ATAVISM — TRANSMISSION OF PHTHISICAL DISEASE. Family history, showing a marked tendency to consumption, derived apparently from the grandparents, without involving the intermediate generation. 1st Generation. Paternal grandfather, died of " decline in bowels," set. 62. Paternal granduncle, died of consumption, aet. 30. Paternal granduncle, died of consumption, set. 50.

Paternal uncle, living and well, set. 66. Paternal aunt, died, three weeks ill, "sore leg," set. 50. Mother, no consumption traceable in her family, living and very healthy, set. 72. 3d Generation. Patient and four of his sisters all died of pulmonary phthisis, ages from 23 to 45 years. A brother died of a " rack or strain," followed by purging and vomiting, set. 23. Six other brothers and sisters living and well, ages from 27 to 52 years. Of these several have families ; one cousin died of consumption, set. 20, in one family ; in another, two cousins died of " water in the head," and one died of "overgrowth with swelling of the belly." A point in the family history to which special importance is attached by som^ authorities concerns the time of appear- ance of the disease in the j^arents as compared with the time of the birth of the child. In the case of syphilis it is obvious that if the child were born before the parent contracted the disease there could be no transmission. It seems that even in the case of gout, and some other hereditary constitutional diseases, the children born after the pronounced appearance of the disease in the parent are more prone to the affection than those born before that period. Even after allowing for all these sources of difficulty in interi)reting the family history, we must remember that the members of the family who might have been affected, if they had lived, may have been cut off by accident, or ])y what we FAMILY HISTOKY. 73 might call accidental diseases, such as fevers and some other acute diseases; or we may encounter the difficulty of the dis- eases in question usually appearing at ages beyond those avail- able in the study of our patient's history. A large family, with all the living members grown uj) to middle or advanced life, should show pretty clearly the tendency of their family constitution, but even then cancer, for example, is so notoriously disposed to appear at the later periods of life that it may still be absent from the family history at the time we are in search of it. A child may die of cancer supposed to be quite unknown in the family till j^erhaps his parent dies of the same disease many years later. This defect might be supposed likely to be supple- mented by the history of the uncles and aunts, or of the grand- parents or the granduncles and aunts of our patient ; but there is first of all the enormous difficulty of getting information so extensive and so precise, and even then, unless the numbers be large in such families, we may readily miss the evidence of a family taint. In tubercular disease, likewise, especially in children, the family tendency may not have had time to manifest itself in the other members at the date of our inquiry. The number and ages of those living come in here to enable us to guess, as it were, at the j)robabilities of such a tendency having had time and opportunity to manifest itself, if really present. A deceptive apj)earance of soundness in the family history may sometimes arise from there being no account of deaths or illnesses connected with the suspected disease, when really from smallness in the number of the family, or from deaths due to fevers and other accidental diseases, no oppor- tunity was allowed for the morbid tendency to show itself. Such a family history, although not "bad," is not "good;" it is defective in its evidence. In a larger family, again, a stray death may have occurred from phthisis or rheumatism, due, perhaps to exceptional exposure or unfortunate modes of life, although no great tendency to such disease existed in the family. We must, therefore, consider all these points in trying to form a sound judgment. CHAPTER III. TEMPERATUKE— PULSE— GENEEAL SIGNS OF PYKEXIA. Temperature. An increased heat of the body is one of the oldest and most widely recognized signs of fever. It may be estimated roughly by applying the hand, or j^erhaps the back of the hand, to the surface of the patient's body, selecting some of the sheltered parts, such as the axilla, the groin, and especially the abdo- men. It must be borne in mind that a certain coldness of the extremities and of the exposed parts often coexists with a great elevation of the temperature in the interior of the body, and even in the axilla or groin. The variable temperature of the observer's hand, moreover, must be remembered as a fruitful source of fallacy, so that when we aim at accuracy in deter- mining the degree of pyrexia, as febrile heat is often called, or at certainty in pronouncing its absence, we must have recourse to the thermometer. Clinical thermometers should be sensitive, and should have the bulb of such a size and shajDe as to be adapted for introduc- tion into various parts of the body. The graduation should be on the stem itself. Accuracy in the instrument is, of course, desirable in all cases, and is especially important if any startling deviation from the usual range of temperature happens to be discovered. Certificates of accuracy, or of the amount of error in the scale, may be obtained by sending the instruments to be tested at Kew Observatory. It is important to have the observations made, if possible, with the same instrument, in the case of a given patient ; in this way, although there may be some slight error in the instrument, the changes in the patient's temperature, noted from time to time, are really but little affected by such errors ; the variatiotis in a patient's tem- perature, from time to time, are usually more im})ortant in the case than the absolute height of the reading within half a degree on either side. If the self-registering maximum ther- mometer be used, care must be taken to shake down the index TEMPERATUEE. 75 below the probable temperature of the patient, before it is applied ; if an instrument without any registering index be used, care must be taken to read it in situ, as, of course, the mercury falls whenever the instrument is removed from the body. In applying the thermometer to the axilla, the following points must be attended to : if there be much sweat, the skin should first be wiped dry ; the bulb should be introduced deeply into the axilla, under its anterior or pectoral fold, with the point directed slightly upward, and the arm must be kept close against the thorax ; it is sometimes a good plan to make the patient keep the arm in position by means of his other hand, or by lying slightly on the arm during the observation ; strong muscular effort on the part of the patient in holding his arm by the side is apt to cause a hollow in the axilla, and so to remove the soft parts from the bulb of the thermometer. We may, indeed, require some one to hold the instrument in posi- tion if the patient has not strength or intelligence enough to keep the arm closely applied ; care must be taken that no folds of the underclothing interpose between the bulb and the skin; it should also be seen that the instrument does not slip down or project behind and beyond the axilla. The thermometer must be left in position till the mercury maintains the same level for two or three minutes. The time required for an accurate measurement of the temperature in the axilla depends on this cavity requiring to be kept closed long enough for it to reach its maximum heat, as this may have been reduced by exposure to the air ; it is clear^ therefore, that a very different length of time may be required in different observations ; the only accu- rate method is to see that the maximum is really attained, as judged by the stationary position of the mercury ; a stationary position for two or three minutes is found to be sufficiently accurate for ordinary clinical purposes. The routine method of keeping a thermometer in the axilla for five minutes only, and then entering the reading, cannot be too strongly con- demned as often extremely fallacious ; and yet this method of observation is sometimes resorted to in order to prove the efficacy of antipyretic treatment by iced compresses applied to the chest ! When self-registering instruments are to be used by unskilled persons, who cannot be trusted to read the index, fifteen minutes may be named as a proper time for the applica- tion of the instrument. If the arm be kept closely applied to the side for fifteen or twenty minutes, immediately before the thermometer is introduced into the axilla, the necessary time for the actual observation may be shortened. Heating the 76 TEMPEEATURE. bulb of the instrument beforehand, to a temperature near the blood-heat, is desirable if the weather be cold or the bulb be large, but it does not materially lessen the time required for the observation, as this depends on the state of the axilla much more than on the coldness of the instrument. If the mouth be used for testing the temperature, the bulb should be placed under the tongue and the lij^s kept shut, the breathing being performed through the nostrils. The mouth resembles the axilla in being sometimes open to the air and sometimes shut, and similar remarks apply to it as to the axilla. The mouth may often be used with advantage for testing rapidly the temperature, in an approximate manner, in dis- pensary or private practice, as the clothes do not require to be removed for the purpose. Care must be taken that nothing very cold (as ice) has recently been in the mouth when the temperature is being tried in this place; very hot liquids recently taken are also apt to affect the readings here. The rectum gives results more accurately and rapidly than either of the preceding, and it is sometimes preferable, especi- ally in the case of children, where axillary measurements are often irksome, tedious, and unsatisfactory. The bulb is oiled, and introduced two inches within the bowel, and held steadily till the maximum is reached ; this always occurs in two, three, or four minutes, because w^e have not to contend here against the cooling influence of the air, as in the case of the axilla and mouth. If very young, the child may be placed Avith advant- age on his left side, in the nurse's lap, with his face to her right breast. The objections to the rectum (apart from the annoyance and exposure involved) are the possible compres- sion of the bulb by the muscles of the bowel Avhich may force the mercury mechanically up the stem of the instrument ; the chance of the bulb being inserted into hard feces and so pre- vented from being in contact with the bowel ; and the possi- bility of its being affected by the descent of fluid feces from a higher and warmer level : in any of these cases the tempera- ture of the rectum itself, which is what we desire, may really be missed. The temperature of the rectum as compared with the axilla may be quoted roughly at three-quarters of a degree Fahr., or nearly one-half degree Centigrade higher than that of the axilla. The var/iiui yields accurate and rapid results with the ther- mometer, but is only seldom to be recommended for clinical observations ; the temperature in cases of labor, uterine dis- eases, etc., may sometimes be thus tested with advantage. DAILY VARIATIONS. 77 The urme sometimes affords rapid and useful information, if it be passed directly on to the bulb of the instrument; or it may be passed into a vessel slightly heated, and the tempera- tare immediately taken with a sensitive registering thermom- eter. The time of the day at which the temperature is taken should be noted, or at least clearly understood. The human temper- ature has a daily range, during health, of nearly two or three degrees of Fahrenheit's scale (say a degree or a degree and a half Centigrade), taking the extremes in both directions reached during the 24 hours, and putting the mean at 98.6° F. or 37° C. : the range is more amj^le in cliildren than in older persons ; the temperature rises in the early morning hours, attains a maximum in the afternoon, and falls so as to be at its minimum an hour or two after midnight. In fevers, likewise, there is a daily range, although the temperature is persistently above the normal : the minimum occurs usually some time about 4 A.M. ; the daily ascent varies somewhat, beginning usually earlier in the day in severe than in mild cases, but as a rule it is distinctly manifest about mid-day or toward the afternoon : the maximum may be expected most frequently about 8 p.m., or sometimes an hour or two earlier. In hectic fever, and toward the convalescence in enteric fever, the morning tem- perature is often nearly normal, although the afternoon and evening readings may be very high. (See Figs. 3, 4, and 5.) Sometimes, hoAvever, the type is " inverted," the temperature being low at the hours at which in ordinary cases it is high, so that it is high in the morning and low in the evening. The importance of having the observations made at the same hours, so as to have them fairly comparable with each other, becomes thus very apparent, as otherwise we might mistake the diurnal variation for a real aggravation or diminution of the fever. This likewise shows the danger of relying on one observation (especially in the morning or forenoon) as proving the absence of pyrexia. Frequently repeated observations in the course of the day reveal some curious and important facts in the history of the temperature. This sometimes dips down to the normal, or even below the normal, for a few hours in the midst of a raging fever, or shortly before the crises is reached : or equally short exacerbations may be detected. In hospital practice only three, or four, or six observations in the day are usually taken, even in febrile cases, so as to avoid fatiguing or annoying the patients ; and in private practice, unless there are skilled nurses or intelligent friends to be entrusted with 7* 78 TEMPERATURE. the observations, only one or two records can usually be ob- tained : the best hours in such cases are about 9 or 10 a.m., and 7 or 8 p. m. If frequent observations are to be made, the best hours are about 3, 6, and 9 a.m., 12 noon, 3, 6, 9, and 12 p. M. ; and special readings should also be made in connection with rigors, convulsions, or other unusual occurrences and also in testing the effect of remedies, or of any special anti- pyretic treatment. Normal and abnormal temperatures may be classified as follows : Fahr. 1 Very low or collapse tem- / peratures. Subnormal temperatures. Normal temperature. Slightly above normal, or sub-febrile temperatures. "(Moderately febrile temper- j atures. I Highly febrile temperatures. Hyper-pyretic temperatures Such a table enables us, on reading the thermometer, to affirm the absence, the presence, or approximately the degree of pyrexia in a patient at a given time ; but this really sup- plies but little information. The temperature may be normal and yet the patient may be dying, or may even be in the midst of a dangerous fever, which will manifest itself in the course of an hour or two as a burning heat. We often, how- ever, detect by the thermometer the presence of pyrexia when we have but little expectation of doing so, judging from the patient's pulse, skin, or general aspect ; or when, as in a rigor, or in cholera, and some other conditions, from the coldness of the surface and extremities, an inexperienced person would think a febrile heat impossible. Very high or very low tem- peratures may also, as a rule, be regarded as evidencing, in themselves, a dangerous condition. Hyper-pyretic tempera- tures occur as serious complications in acute articular rheuma- tism, chorea, enteric fever, and some other diseases, associated usually with great cerebral disturbance. Very high tem- peratures, lasting but a short time just before death, are not uncommon in various diseases. (See Fig. 1.)

(See Fig. 2.) Collapse temperatures, as judged by the heat in the axilla, are sometimes due to a surface depres- sion ; the axilla under such circumstances does not give such a close approximation as usual to the temperature of the Fig. 1 FEBRUARY PLJERPEF^yaJL J_, L Hi llT="iDAY!AFtER (dufeF{Y?)^Rk^iipqLAS Fig. 2.

Very low temperature in rectum just before death. blood : in such conditions if we wish to know whether the internal heat is really lowered we must apply the thermom- eter to the rectum or vagina ; but the internal temperature may also be much depressed in collapse. (See comparison of terminal temperatures in Fig. 17.) The thermometer only supplies information as to pyrexia at the given time ; its indi- cations, therefore, must be interpreted with due caution, and in view of other symptoms and of the known facts of disease. The period'wity of the temperature is one of the most inter- esting and important points to be considered. It has already been pointed out in connection with the time of day for taking observations that even in health, or after convalescence is 80 TEMPEKATUKE. established, constant oscillations are going on. An illustra- tion of these small variations may be seen in the diagram showing the relapses in enteric fever ; for a whole month the temperature was normal, but slight variations, seldom exceed- ing one degree F., habitually occurred. (Fig. 18, tempera- ture during September.) In febrile diseases also the rise of the temperature from morning to night is usually well marked — the whole range being, of course, maintained at a higher level. (See the febrile stage in enteric fever, Fig. 18 ; relapsing fever, Fig. 9; pneumonia. Fig. 14 ; and other diagrams.) In hectic fever we have not unfrequently the morning and even the forenoon temperatures nearly normal, while at night Fig. 3. 9 10 II 12 13 14 15 16 17 18 19 20 21 ZZ 23] io5°-H-H ... -- jiiinimiHMiivHiHi siiiiiiiiiiinnii 1 nniiAHiuifiiiiinwi^^^^^ Diagram showing the daily range of temperature in a boy six years old affected with phthisis and tuberculosis ; observations were made in the rectum six times in the twenty-four hours, and the maximum and minimum temperatures have been recorded on the diagram; the minimum always occurred in the morning, usually about 6 A. m., and the maximum always in the afternoon, sometimes as earlj' as 2, usually about 4 or 6, and occasionally somewhat later. The pulse varied from 136 to 148, and the respirations from 44 to 60. a high degree of fever is reached. When the fever falls, but does not completely intermit or disappear at some part of the day, it is termed " remittent ; " this form of pyrexia is very common in phthisis and tubercular diseases ; it is also often found in some stages of prolonged suppuration. The remis- sions of hectic fever are well shown in the diagram, the highest of the temperatures noted in the evening and the HECTIC FEVER 81 lowest in the morning having been selected in drawing up the chart on page 80. (See Fig. 3 ; compare also the daily oscillations at the termination of enteric fever, as shown in Fig. 15.) When this diurnal variation in hectic fever is studied more closely, the temperature is found to rise with considerable regularity at certain parts of the day, usually about midday or in the early hours of the afternoon. This rise is often very sudden — an elevation of three or four degrees F. may be attained within three or four hours, or even less, so that the temperature may pass from the normal level to a high fever height within that time. This daily periodicity, with a Fig. 4. Diurnal range of hectic fever in a phthisical child, every two hours in rectum. Temperatures daily or quotidian paroxysm, is well shown in two diagrams from cases of phthisis. In the one (Fig. 4) the temperatures are those of a child taken every two hours in the rectum; in the other the temperatures were those of an adult taken every four hours in the axilla. (Fig. 5.) In other forms of tubercular disease the type of hectic fever may be departed from, and in acute miliary tuberculosis, in particular, we not unfrequently have an approach to the type of a more or less severe continued fever, as shown in the chart from a case of this disease in a child. (Fig. 6.) The daily paroxysm constitutes the peculiarity and supplies 82 TEMPEKATURE Fig. 5. HECTC FflVEf PHTHISIS. ioo°444- Diurnal range of the temperature in hectic fever. Fig. 6.

The regularity of the paroxysms as to time, the rapidity of the ascent and descent, and the completeness of the intermission, are shown in the accompanying temperature chart. (Fig. 7.)

One day may be omitted ; or, in other words, the intermission may last a full day : in this way the Fig. 7. ^ ■ - C. 1881. 13^" Y ■'■ r- 1 uhI 15'" i J 1 Y 16' c. ■:4l .140 .39 106- i ; 105- : Q 1 fffHWWMP Hlnnili MMI Htm mni iHim illHI wmii IBflHI ■mi ■MU wmm wmm nriiiiii umm mull ■mm HI^IIH nHKH 103: ,102: r 101: -H — loo; - ^ 99- 9a — i Daily paroxysms in intermitteut fever : quotidian ague : temperature in axilla. attack occurring on one day is followed by another, not on the second, but on the third day ; hence the name " tertian " is applied to this form of ague. (See Fig. 8.) A further variation of the paroxysm in intermittents is when the fever occurs not on the third but on the fourth day — there being two days of an intermission — so that the name " quar- tan " is applied. This return of the fever, after it had apparently gone quite away, sometimes assumes a different periodicity. We may have a whole w^eek free from fever, and the patient may seem so well that if the regularity of the disease were not so well known, we could scarcely believe in the return of the whole train of symptoms on the thirteenth or fourteenth day. This peculiarity furnishes the distinctive name of " relapsing fever." This remarkable disease, called also "famine fever," has appeared in this country on several occasions in the form of an epidemic.

DURiNt ATTACKS Intermittent fever : tertian ague : temperature in axilla. terval. The paroxysm in a simple quotidian intermittent can only, of course, last a part of a day : the same may be said of simple forms of the tertian and other varieties also ; but in bad forms the intermissions become incomplete, and the pyrexia assumes the remitting type, or even merges into a continued fever. In relapsing fever the duration of the pyrexia is just as definite as that of the interval, althougli in both a little varia- tion occurs. The first attack usually lasts five to seven days, and the relapse three or four — the interval between them varying also from about six to eight days. In smallpox the primary fever undergoes on the third day a material reduction, or it may be, in the modified variety, a complete subsidence, coincidently with the appearance of the eruption. (See Fig. 10.) In lobar pneumonia the pyrexia terminates with as much abruptness as in the infectious fevers ; the date of the crisis, however, may vary from the third to the tenth or twelfth day. Very definite as to duration is the ENTEKIC FEVEK.

(Compare duration of attacks in Fig. 18.) Even this fever, however, cannot go on indefinitely ; a fever course in this disease prolonged beyond five or six weeks can usually be found to depend on complications, or perhaps on relapses. Tliese are, no doubt, sometimes difiicult to detect or. to prove in particular cases, although the general statement given above may be accepted. The subject of re- crudescences and relapses, however, falls to be considered in another section of this chapter. The ab.sence of any recognizable 'periodicity hi the pyrexia con- stitutes a feature of pysemic fever which has some value in diagnosis. In this disease we may have paroxysms occurring daily, or sometimes twice or thrice in a day. These frequently coincide with the occurrence of severe rigors. No definite relationship to days or hours can be made out in such cases, the temperature running up and down in the most erratic manner, and we are sometimes afforded, on this account, grounds for suspecting the presence of this formidable dis- ease. Another variety of the absence of periodicity in the tem- perature (at least as to duration) is found in those cases where the fever course appears to be going on indefinitely for many weeks or months. In whatever way such cases may have begun, we must, under such circumstances, carefully consider the probability of having to do with some form of tubercular disease, or, it may be, with chronic suppuration. The manner of rise in the temperature and the duration of the jyyrexia, with regard to the date of the illness, are often most valuable for diagnosis. Some diseases are remarkable for the rapidity with which the temperature rises. Most of the short fevers or febriculse, as they are called, begin sud- denly, and rapidly attain their maximum. Amongst these are the surgical febriculse (immediately after operations), and the feverish attacks, associated with obscure and often tran- sient disturbances of the general health, due to disorders of the digestive organs, especially in childhood. The following likewise usually show a rapid development of pyrexia : Suppu- rations, and most of the diseases ushered in with severe rigors, ague (Figs. 7 and 8), tonsillitis, acute nephritis, scarlatina, smallpox (Fig. 10), pneumonia (Fig. 13), pleurisy, peritonitis, meningitis of the convexity, relapsing fever (Fig. 9), erysipelas, pyiemia, parotitis. All of these may have very high tempera- ENTEEIC FEVER. 87 ture on the first day of the illness. Occasionally in malignant cases of smallpox and scarlet fever the disease proves fatal so early that the system is overwhelmed with the poison and never shows any febrile heat. Measles sometimes almost reaches its maximum temperature on the first day of the fever, although a marked fall usually intervenes between this and the maximum temperature reached on the fourth or fifth day with the full development of the rash (Fig. 11). A great and Fig. 11. Temperature iu measles (Wunderlich). Fall of temjjerature after the first clay's fever. Great rise on the fourth day, with the appearance of rash. Maximiun ou fifth day, with full development of the rash. sudden elevation of the temperature is so common in the dis- eases named above that they should always be thought of in doubtful cases. Other diseases are rather characterized by a more gradual and progressive elevation of the temperature ; this is especially observed in enteric fever (Fig. 12), although exceptional cases of this disease occur in which the pyrexia attains its maximum at what seems to be the very beginning of the illness. But in enteric fever, as a rule, the manner of rise is such that during the first three or four days every day marks an ad- vance on the previous one, the morning temperature falling from the elevation of the previous night, but being in excess of that of the previous morning. In typhus fever the ad- vance of the temperature is somewhat more sudden than in enteric, but iu it, likewise, several days usually elapse before the maximum, or any very high point is reached. In articular rheumatism, affecting several joints, in catarrhal pneumonia, 88 TEMPEKATURE. in acute tuberculosis, and phthisical affections, the ascent of the temperature is usually spread over several days. Fig. 12. Gi'adual risu of tempeiatuio at the beginning of enteric fever. The duration of the pyrexia often assists the diagnosis. The complete and continued subsidence of the temperature, within a week, may serve to exclude typhus and enteric fevers ; its prolongation for twelve or fourteen days, without any febrile rash or any evidence of local inflammatory mischief, may sometimes guide us to the diagnosis of enteric fever (see Fig. 18 for first fifteen days); or its persistence may, in a chest complaint, lead us to the diagnosis of phthisis (see Fig. 3), or empyema. The duration of the pyrexia is also controlled by the periodicity discussed in a previous section. The decline of the tem2')erature, both as regards its date and maimer, is of the utmost importance in prognosis and some- times in diagnosis. The favorable termination of a febrile disease, by a rapid fall of the temperature to the normal or subnormal level, constitutes a crisis. This fall may amount to three or four degrees or more in twelve to thirty-six hours. This method of termination is common in pneumonia (lobar), relapsing fever, typhus, smallpox, tonsillitis, facial erysipelas, and febricuhe of various kinds. Its suddenness is represented in the diagrams of ague (Figs. 7 and 8); of pneumonia (Figs. 13 and 19); and of relapsing fever (Fig. 9). In smallpox a critical fall of the temperature occurs with the appearance of the rash on the third day (see Fig. 10), although in severe cases it may rise again. It occurs, however, in a modified and less abrupt manner in measles and sometimes in enteric fever. (See Figs. 11 and IG.) The suddenness of the crisis varies DECLINE OF THE TEMPERATURE, 89 much in different diseases and even in different cases ; in many- cases of typhus a gradual diminution, extending over three or four days, is sometimes so distinct as to make the crisis in this disease much less pronounced than is usually taught, and to assimilate it rather to a lysis ; frequently, however, the critical fall of the temperature is very marked. Lysis is the term applied to a more gradual diminution of the fever, spread over several days ; this may usually be ob- served in scarlatina and broncho-pneumonia, occasionally in pleurisy and pericarditis, and also in acute rheumatism. The Fig. 13. Fig. 14. Crisis. Temperature in lobar pneumonia (Wunderlich). Sudden crisis on eighth day ; pseudo-crisis on fourth day. Lysis. Temperature in broncho-pneu- monia (Wunderlicli). Gradual fall extending over four days. defervescence in the two forms of pneumonia is usually strongly contrasted ; in lobar or croupous pneumonia we have a sudden crisis ; in catarrhal or broncho-pneumonia we have usually a lysis. (See Figs. 13 and 14.) Sometimes the lysis assumes a remitting character, the morning temperatures falling gradually or suddenly, and the evening temperatures preserving for some days nearly their former elevation. This is not uncommon in enteric fever. (See Fig. 15 ; compare, also, the gradual de- scent of the temperature in the three attacks shown in the diagram of enteric fever. Fig. 18.) Certain fallacies beset the estimation of the value of a fall of temperature. It is very often found that a high, febrile tem- perature undergoes a great diminution on the day after admis- 8^ 90 TEMPEEATUKE. sion to the hospital ; this seems often to be really due to an unusual elevation on the day of admission, arising from the disturbance of moving the patient, etc., so that little weight is attached to the temperatures of the first day's residence in Fig. 15. Eemittiug lysis in euteric fever. hospital. Occasionally a pseudo-crisis, as it is called, occurs a day or two before the real crisis, the temperature, after being low for a few hours, mounting up again to its former height ; this pseudo-crisis affords no guarantee of a subsequent genuine crisis. (See Fig. 13.) Collapse temperatures may stimulate a crisis, although really indicative of serious complications, as in the intestinal hemorrhage of enteric fever, where the cause of the fall may not always at first be quite apparent, (See Fig. 16.) The fatal termination of some cases of febrile dis- ease is often associated with a marked fall in the temperature, and occasionally this occurs under such circumstances as to simulate an improvement. (See Fig. 17 ; compare also Figs. 2 and 6.) Collapse temperatures may occasionally be detected for a few hours in the midst of a raging fever, or just before the terminal exacerbation of a febrile disease, whether it be favorable or fatal. Sometimes the decline of temperature in a tubercular subject is connected with the supervention of cerebral complications. (See Fig. 20.) Hecrudeseenees ; relapses; complications.

By this term is meant a reascent of the temperature after a defervescence which from its extent or its duration cannot be i*egarded as complete. Such exacer- bations often depend on the extension of the mischief; for example, from new portions of the lung being involved in pneumonia, or to advancing intestinal ulcerations in enteric fever. Such recrudescences are distinguished from " relapses :" the latter only occur after a definite period of complete apy- rexia. Theoretically the distinction made is that in recrudes- dences we have merely the extension or aggravation of mis- chief already existing : in relapses we have new mischief ab initio. Enteric fever is particularly liable to both, and in this dis- ease we would expect to find new or recent deposits in the intestinal glands at the date of a relapse. No doubt if these fresh deposits in a relapse occur before the subsidence of the first febrile attack, we may have an overlapping of the first febrile period by the second : in this way a relapse might appear to afifect the temperature after the manner of a recru- descence ; and in such a case nothing but a careful post- mortem examination, if the illness proved fatal, could settle the distinction. True relapses in enteric fever occur after an interval of a few days perfectly free from pyrexia, and when the patient appears in other respects to be recovering ; usually this interval is about a week or less, but ten or twelve days are not uncommon. A diagram is here given showing a very prolonged period of intermission — a full month — between the first and the second attack. This length of interval is very exceptional, but the evidence of its reality is complete; if the temperature had not been taken so carefully during the pro- longed interval it might have been plausibly contended that a relapse had occurred during this month of such a slight nature as to have escaped recognition, and this is a thing which should be remembered as quite likely to occur. Between the first and the second relapse, in this same case, the apyretic period was of the usual duration of eight or ten days. (See Fig. 18.) The rise of the temperature at the beginning of a relapse in enteric fever is much more sudden than in the same stage of the first attack. (See Fig. 18 ; c()in[)are temperatures at the beginning of August with those at the beginning of October and November; compare also Fig. 12.) The reascent of the temperature may be due to complications. SURFACE THERMOMETERS. 95 These may occur at any stage of an illness or after con- valescence is established. In any case, whatever may be the usual mode of onset of the disease under other circumstances, the rise of temperature with the complication is usually abrupt. Complications may also, by their presence, delay a crisis, as is often seen in bronchitis complicating typhus, and in this way prolong the illness ; or the complication may impress a remit- ting character on the fever, as is seen in the hectic fever of phthisis, sometimes developed in a case of pneumonia or pleurisy in a tubercular subject. The temperature of con- valescents, however, it must be remembered, is very unstable, and there is often a serious-looking disturbance of the temper- ature in them from very slight causes (indigestion, constipa- tion, fatigue, excitement, etc.), which would not thus affect the healthy. For this very reason, temperature observations in this stage are highly important, as affording the best evidence of continued safety or the first alarm of threatened danger. From what has been said, it will be seen that the temper- ature, although of the utmost importance in diagnosis and prognosis, must not be regarded too exclusively, or aj^art from the other facts of the case and the general state of the patient. The natural course of the temperature in the various diseases, as ascertained by experience, must be kept in mind ; a degree of elevation or a special behavior of the temperature may have a very serious significance in one disease and very little in another. The comparison of the temperature with the pulse often serves to correct our views of each, and although they usually rise and fall together (see Fig. 19), certain deviations occasionally or habitually occur in special diseases, or in certain stages of such affections, which are of the greatest significance ; (for example, at the beginning and the end of enteric fever, and toward the end of tubercular meningitis ; see Fig. 20). Surface Thermometers. In the precedino; sections the ordinary clinical thermometer is sup- posed to be applied in such a way as to give us an approximation to the heat of the blood. Surface thermometers are used to give an estimate of local or surface temperatures. They are made with broad or spiral bulbs so as to expose a large surface to the part tested, and these bulbs are enclosed in small cavities, ingeniously made, so as to lessen the loss of heat when applied. They are sometimes sold in pairs, so that two parts, or two sides of the body, may be tested simul- taneously. Hitherto their use has not been very extensive, nor have the results so far obtained been very important. They enable us, however, to record in figures diflferences in local temperature which 96 PULSE. may be appreciable in other ways, as in cases of obstructed arteries in limbs, atrophic infantile paralysis, local inflammation or hyperaemia, etc. The difficulty in using them depends on the length of time required to heat up the air chamber containing the bulbs of mercury: on the variation in the results obtained, within similar periods of time, according as the instrument is pressed more or less firmly on the part if the thermometer is tied : on the heat of the hands of the observer complicating the result, if the instruments are held by him; and apparently also on a prolonged application, carried to the extent of obtaining a stationary condition of the mercury, ceasing to afford a true surface temperature, and yielding rather an approximation to the internal heat, from the part being so long covered over by the instru- ment. It seems best to use a pair of instruments (carefully compared), so as to have the applications simultaneous, if dift'erential observations are required ; otherwise the loss of time and the altered conditions of heat render the results obtained by the transference of the same instru- ment from one part to another very uncertain. In applying them they should be held in an exactly similar manner, and pressed with as nearly as possible equal firmness. Moreover, the readings from minute to minute during the rise of the mercury should be noted in each instrument, as the difference in rapidity of the rise appears to indicate the surface temperature in a more striking manner than the figures ultimately attained. In checking the results by a second application, the instruments may be changed so as to be applied to different sides. The Pulse affords such valuable indications for the determination of the febrile state, and for estimating the general strength of the patient, that the noting of it is a matter of routine in all cases. Apart from fever, however, there are other important points to be attended to in noting the pulse, and to prevent repetition these also will be considered here. T he frequency of the pulse is not difficult to estimate; the pulsations in the artery, the radial by preference, are counted for a quarter or for half a minute, with the aid of a watch furnished with a seconds dial, and the number per minute is thus calculated. For delicate inquiries, the pulse should be counted for a whole minute, or even for two consecutive minutes, the number being halved of course in stating the result. Other points also must be attended to when accuracy is desired. The normal rate of tlie pulse varies with age, and also in different individuals (according to temperament) ; in the adult it is usually stated as being about 72, but it is some- times higher and often much lower : it is more rapid in child- hood, and in infancy is often about 100, apart from disease. In the same individual the pulse varies with position, both in health and disease, the rate being higher when the patient is PULSE-EATE. 97 standing than sitting, and higher while sitting than lying down : any movement or exertion tends to increase the rate, and mental excitement is particularly apt in some people to make it rise very high. Hence, in estimating the pulse or its changes from day to day, in such a delicate inquiry, for ex- am23le, as the estimation of an incipient defervescence, care must be taken to have results really comparable, and not to compare the rate of the pulse while the patient is sitting up in bed with that obtained on a previous day while he was lying still. The influence of meals is also very great, the pulse rising considerably after a full meal, and especially after the use of stimulants in the healthy state ; in febrile diseases, however, the effect of stimulants is often to reduce the pulse- rate when their influence is beneficial. Apparently the habitual use of spirits for years tends to keep up a persistently high pulse-rate natural to the individual, quite apart from any febrile disease or any special excess. The time of day has a certain influence in the normal state, even apart from food and exercise ; the pulse-rate, like the temperature, is lower during the midnight hours, and rises in the early morning, but the exact time of these changes varies ; they are usually later if occurring in febrile diseases than in the normal state. Sleep has a tendency to reduce the pulse-rate. Considerable tact is often required to secure a fair estimate of the pulse; in some cases we obtain the best chance at the beginning of our visit, counting the pulse before the patient is disturbed in any way by speaking or moving ; or perhaps, especially in children, during the quietness of sleep. With some patients, again, the approach of a stranger sets up the pulse to such a height that we must wait till it has subsided. The lowest rate we can obtain is the most reliable index in judging the degree of fever. A fit of coughing, or the exertion of moving or sitting up for the purpose of auscultation, etc., often com- pletely spoils the value of the pulse-rate as a gauge of pyrexia. It is in such cases that temperature observations come in as a valuable check (see " Temperature "), and these often assure us that the rapidity of the pulse is due to excitement, general weakness, or irritability of the heart, apart from fever. As a rule, the pulse and temperature in febrile cases are elevated or depressed, and rise and fall together (see Fig. 19) ; but strik- ing diflerences occur in certain cases. The pulse is often but little elevated in the beo-innino; of enteric fever, at a time when ... the temperature is very high ; while after the recovery has begun, the pulse may be rapid from weakness, although the 9 98 PULSE fever temj^erature has completely fallen. And in some patients, Avith febrile or inflammatory disease, the pulse is Fig. 19. Crisis in lobar pneumonia: tlie diagram shows the sudden improvement in temperature, pulse, and respiiation ahiiost simultaneously. often quite normal in rate, although the temperature is per- sistently high. On the other hand, in incipient phthisis, we SLOWNESS OF THE PULSE, 99 may have a constant elevation of the pulse with but little change in the temperature. In cerebral cases, also, the rela- tionship of the pulse-rate to the temperature is subject to Fig. 20.

The pulse, which fell at first with the temperature, ran up toward death, although the temperature remained comparatively low. special variations ; the terminal stage of tubercular meningitis is often characterized by a high pulse and a comparatively low temperature. (See Fig. 20.) The ratio of the pulse-rate to the frequency of the respira- tion, is sometimes of value as an index of the existence or supervention of respiratory disease; for although a little acceleration of the respiration is natural in the febrile state, any great disturbance of the ratio usually points to such complications. (See " Respiration," Chapter IX.) Sloimiess of tJie pulse has been just referred to as an excep- tional occurrence in the febrile state in the sense of there not being the usual acceleration. We sometimes find, however, an absolute reduction in the pulse-rate in certain diseases ; 40 to 50 beats are not uncommon, and we may have 30, 20, or even less. These low numbers are sometimes due to the efiect of digitalis used medicinally. In fatty degeneration of the muscular fibres of the heart a very low pulse-rate is an im- 100 PULSE. portant sign of this condition. Occasionally in epileptics the pulse is very slow ; and in various brain diseases, particularly when there is pressure or effusion, the pulse-rate falls ; this fall, however, may be followed by a terminal exacerbation. (See Fig. 20.) The force or strength of the pulse often guides our prognosis, and directs us in the treatment, especially as regards stimu- lants. It is not easily estimated by the beginner ; it requires experience and the watching of cases (especially febrile cases), from day to day, for the education of the fingers. Some- times the radial pulse gives a fallacious idea of Weakness, from the vessel being of unusually small size Oiigh division or other abnormality). Pressure on the arm from the patient's position in lying on it, or some accidental tightness of the dress, may also interfere with the radial pulse. Moreover, the radial arteries on the two sides are often of very different size, and so we find that errors sometimes arise from our de- tecting a difference due merely to an accidental change in the method of observation — the other arm having, perhaps, been taken instead of the one usually felt. In doubtful cases the radial, brachial, or other arteries on both sides should be ex- amined, and the heart's sounds should be listened to. When the pulse is really very weak, the first sound of the heart is usually diminished and sometimes almost suppressed, the second sound remaining distinct. Differences in the strength of the two radial or other pulses are often of value in diag- nosis, particularly in cases of aneurism of the arch of the aorta, giving rise to more or less obstruction of certain branches. Sometimes the two pulses are not perfectly syn- chronous from similar causes. Occasionally, also, the dimi- nution or obliteration of an arterial pulse serves to indicate the occurrence of embolism, but care must be taken to see that these differences are not due to unusual distribution of the vessels. A survey of the arteries should be made, both wdth the finger and eye, when judging of the force of the pulse, and the examination sliould not be limited merely to tlie part of the radial artery at the wrist; by extending our observation we may detect any undue rigidity, twisting, or unevenness of the vessels. Sometimes other arteries must be examined to satisfy ourselves (m this subject ; the temporals and the branches of the thyroid axis are selected for the purpose of testing the smaller vessels, the brachials and the femorals as a sample of the larger. TJie hardness of the pulse-heat must be distinguished from EIIYTHM OF THE PULSE. 101 the hardness due to the state of the arterial walls just referred to. The walls may not be rigid and yet the pulse may feel like a cord. This is an indication of high arterial tension, and is often noticeable in various forms of Bright's disease, and particularly in cases of the contracted kidney. The rhythm of the pulse is in health j^erfectly regular, so that any deviation from this should be noted. Sometimes there is a distinct intermission, a loss of a beat at regular or irregular periods, but there may be such a loss in the radial pulse without any corresponding intermission in the heart's sounds or action ; there may thus be a marked difference in the pulse-rate as counted at the wrist and at the heart, the strength of the cardiac contraction being unable to produce a proper beat at the wrist : such abortive beats, may sometimes, however, be recognized by sphygmographic tracings. (See "Sphyg- mograph," Chapter XVI., under "Irregularity.") Or the irregularity may consist of two or three hurried beats followed Fig. 21. This diagram, from Foster's Physiology, shows the influence of the respiration on the pulse in a healthy subject. The upper tracing is the pulse. The lower curve gives the movements of the chest wall. During inspiration the pulse-waves diminish in height and become more dicrotic, while during respiration the height of the pulse-waves is in- creased, while their form tends more toward that of a pulse-wave with a raised arterial pressure. This diagram shows one form of the eflect of the respiration on the pulse, hut this effect varies considerably in different experiments and under different conditions.

This change in the strength and character of the pulse can be made out in certain cases to be associated with the respiratory movements, or with the occur- FiG. 22.

I corresponds with inspiration and E with expiration. ^ rence of convulsions, or some other visible phenomena. (See Figs. 21 and 22 for illustrations of this in healthy and dis- eased states.) The significance of irregularity of the pulse is most varied. It sometimes affords one of the first indications to brain mis- chief, especially in children, or of incipient pericarditis. It is very common in various forms of heart disease, at all ages, especially in mitral disease, fatty heart, and the degenerations incident to old age. Apart from these, however, it is often due to functional disturbances, esjoecially such as are asso- ciated with indigestion, flatulence, excessive smoking, etc. It is likewise developed, not unfrequently, through nervous agi- tation, in certain persons, just as acceleration of the heart's action or fluttering is produced in others from thesame cause; concentration of the attention on the intermission is apt in such cases to increase the irregularity, or the frequency of the intermission. Some persons, apart from any medical knowl- edge, have an obscure sensation of the intermission, which causes a start or a shock. A more serious form of disturbance occurs in the intermittent pulse of typhus fever and other grave diseases ; this is almost always a sign of danger from failure of the heart, but here also exceptional cases occur, of less grave import, due to the peculiarities of the individual, or to his habitual liability to this disturbance. An intermis- sion in the pulse sometimes marks the beginning of the epi- leptic fit. In states of debility, during convalescence from serious diseases, and in the case of children after enteric fever, for example, intermission of the pulse is sometimes associated with unusual slowness, and is specially noticeable at night. SYMPTOMS OF FEBEILE STATE. 103 This does not imply any real danger, and, indeed, in children who are practically healthy intermission of the pulse may often be detected during their natural sleep. Dicrotous jndse. — Somewhat allied to the rhythm is the curious double beat in the pulse sometimes felt in febrile cases. It is not uncommon in the convalescence from typhus fever. This is best felt by applying the tips of the fingers very lightly over the vessel, avoiding any such pressure as would extinguish the weak second beat. The sphygmograph brings out this dicrotism very clearly. Another form of double beat, with the beats more distinct and more closely together, has been named the "pulsus bigeminus." These peculiarities are best discussed in connection with the sphyg- mograph. (See Chapter XVI.). The pulse of unfilled arteries, characterized by a sudden fill- ing up of the artery followed by a very sudden collapse of the vessel under the finger, often enables us to suspect, or sometimes even definitely to recognize, incompetency of the aortic valves, on feeling a patient's pulse. The peculiarity is brought out in a more striking way by raising the patient's arm vertically while feeling the radial pulse ; visible pulsation throughout the arteries and especially in the neck is usually very marked. This is also spoken of as the " water hammer " pulse from its sudden slapping or jerking character; "the pulse of aortic regurgitation " from its cause ; and " Cor- rigan's pulse " from its describer. It also occurs in thoracic aneurism. (For capillary and venous pidse, see Chapter XVI.) A thrill in the pidse can often be felt in certain cases of cardiac disease (mitral and aortic valvular disease), and this may come out in the sphygmographic tracing. The sphygmograph gives important aid in the study of the pulse. Its indications have a certain value in diagnosis, but in addition to this a little practice with it has great educa- tional value to the student in enabling him to recognize by his fingers many of the peculiarities of the pulse which it records. It seems best, however, to discuss it in connection with the physical diagnosis of the heart, of which it forms an important part. (See Chapter XVI.) General or Constitutional Indications of the Febrile State. In addition to an increased temperature and a rapid pulse, there are certain general signs of fever which are of great 104 SYMPTOMS OF FEBEILE STATE. value. Flushing of the face is common in fever, but care is required to prevent mistakes in judging of this, as the color of the cheeks varies much in different persons, and such an accident as lying on the cheek often produces a local flush, apart from fever; in such cases the thermometer is an invalu- able guide. Sweating is habitual in rheumatic and enteric fever, and in the disturbances of the puerperal state, and is common in certain stages of most febrile diseases ; the total absence of sweat, giving the sense of a dry j^ungent heat to the hand as applied to the skin, is an important fact in the height of fevers, pneumonia, etc. The critical sweats after the height of the fever in ague is passed, or during the crisis of relapsing fever, are only extreme illustrations of the com- mon combination of sweating with the subsidence of a febrile temperature. The sweating is sometimes of daily occurrence, as in the night or early morning sweatings of phthisis, coin- ciding with the diurnal variation of the temperature ; it is also often cold and clammy, and in such cases it may be asso- ciated with bad dreams ; this combination is common in cases of deep-seated suppurations, disease of the bones, etc. The profuse sweatings of py^emic affections may also be referred to here. The influence of remedies in favoring or checking sweating, the nature and amount of the clothing and the softness of the bed are details to be kept in view in judging of special cases. Great liability to sweating on but slight exer- tion is a common indication of weakness quite apart from the febrile state. Sweating is sometimes local, as of the head in rickets ; or of one side of the body, in certain affections of the sympathetic nerve, sometimes apart from any other obvious disease, and sometimes connected Avith aneurismal or other tumors in the chest or neck ; the influence of nervous emotion in the production of sweating is proverbial. Headache and pain in the hack are very common in nearly all the acute speciffc fevers at their beginning, and one or other is usually present, more or less, in all febrile states. Pain in the back is very specially pronounced in cases of smallpox. (Of course, these pains are often due to quite different causes, see Chap- ter VI.) Unequal distribution of heat, a feeling of heat in the head and of cold in the extremities, a l)urning heat in the hands or the feet, a sensation as of cold water trickling down the back, a feeling of chilliness increased on any exposure to a slight draught of cold air, and actual shiverings in all de- grees of their severity are exceedingly common in the begin- ning of febrile diseases, especially before the patient has taken IMPAIKED DIGESTION. 105 to bed ; these sensations often lead him to hang about the fire- place, complaining of cold, although his temperature may be very high ; they tend to disaj)pear Avhen, by proper heating and clothing in bed, the temperature of the various parts of the body becomes more equalized. Young children seldom have distinct shiverings. While shiverings are common at the beginning of all acute inflammatory and febrile diseases, they are especially frequent and repeated in ague, in serious suppurations, in renal inflammation, paroxysmal hsematinuria, and renal colic, in cases of gall-stones, in puerperal fever, and in embolism and pyaemia. The passage of instruments into the bladder often determines a violent rigor with febrile dis- turbance. Rigors also occur occasionally in connection with sudden defervescence. Many of the sensations just referred to, and even actual shiverings, may occur a^^art from fever altogether in nervous subjects ; the thermometer is here, again, invaluable. The digestive functions are almost always im- paired in febrile diseases, and especially at the onset of the specific fevers : vomiting is very common in them, and is some- times very severe and persistent (smallpox, scarlatina, relaps- ing fever, and occasionally enteric fever) ; in other cases sickness or nausea is all that is complained of. The appetite is almost always impaired, and often completely supj^ressed. The bowels are usually disordered ; the febrile state tends, as a rule, to produce constipation, but occasionally diarrhoea is seen to result from the action of the specific poison (as in the beginning of malignant scarlatina), and sometimes there is a special connection between the diarrhoea and the febrile dis- ease (as in ulceration of the bowels in enteric fever, in the inflammatory diarrhoea of infants, and in tubercular and dys- enteric ulcerations) ; at times, however, the looseness of the bowels seems related to the pyrexia as such, and ceases with it : or it may be due to the concurrent impairment of the digestive functions and their inability to deal with the food forced on the patient in his febrile state. The state of the tongue is usually a good index of the constitutional disturbance produced by the fever, so far as the digestive organs are con- cerned fsee " Tongue," Chapter XL). Thirst is almost always present in the febrile state, especially at the beginning of the illness, and notwithstanding the large amount of fluid swal- lowed, the urine is usually scanty and high-colored. Muscular prostration is present in all severe cases of fever, and is often very marked even at the very beginning of some of the speci- fic fevers. Delirium is usually associated, in very varying 106 SYMPTOMS OF FEBEILE STATE. degrees however, with high ranges of pyrexia from whatever cause ; the degree of it, and the date at which it appears, as well as its character, vary much in different diseases. Con- vulsions sometimes take the place, as it were, of delirium, especially in young children, and often mark the beginning of acute inflammatory or febrile diseases in them. A degree of bronchial catarrh is not uncommon in nearly all serious febrile states, and is a special feature in some. Cutaneous eruptions are characteristic of certain febrile diseases (see "Febrile Rashes," p. 137): various symptoms referred to above are dealt with more fully elsewhere ( see Index). The Clinical Significance of the Febrile State is very great, and this remark applies both to the presence and absence of this state in a given case. It has already been explained how the" febrile state is to be judged of; the possibility of our observation occurring in an apyretic interval must be remembered before we arrive at a negative conclusion. Some- times the fact of fever (i. e., pyrexia) is all that can be made out ; but without denying the existence of the old " simple continued fever," we are seldom justified in resting satisfied till we either have referred the pyrexia (1) to one of the specific fevers ("typhus, scarlatina, ague, pertussis, etc.), or have as- certained that it is symptomatic (2) of some special inflamma- tion (pneumonia, pleurisy, abscess, rheumatism, etc.), or at least (8) of some disease known to be associated with febrile disturbance (phthisis, tuberculosis, syphilis, septicsemia, etc.). (1) Specific Fevers and Rashes. — In determining the ques- tion of fever, attention must be directed to the presence or absence of the *' rashes" found in most of the specific fevers (see p. 130). These must be carefully searched for in their favorite situations, and the date of the illness must be consid- ered particularly as to whether there has been time for the appearance of the rash. As the exact date of the illness is often obscure, and as the day on which a febrile rash appears deviates occasionally from the average, some little allowance must often be made for such variations before arriving at a decision. The occasional absence of the rash, in nearly every fever usually characterized by an eruption, must also be re- membered. Other circumstances often render the existence of such fevers very probalile, or indeed certain, even when no rash has appeared. In examining for a febrile rash, other cutaneous eruptions (not of this class) may be detected, and it must be considered whether the eruption discovered is of the kind and of the extent to account for, or to be in harmony SIGXIFICAKCE OF PYEEXIA. 107 with, the febrile movement. Some " skiu diseases," as they are called, are associated with much fever, others with little or none. The possibility of an eruption from the use of medi- cines, and the influence of certain articles of diet must be kept in view (see "Eruj)tions from Medicine and Food," p. 124). Moreover, when there is high pyrexia, a certain congestion of the skin, especially in the dependent parts, sometimes simu- lates a scarlet rash. Eruptions indicative, so far, of certain diseases, although they cannot be called specific, are some- times found in the febrile state^such as herpes labialis in pneumonia, or miliary vesicles in enteric aud childbed fever, rheumatism, etc. Occasionally a rash is found in diseases not usually characterized in this way — thus we may have a rash in diphtheria and relapsing fever, and in the early or pre- eruptive stage of smallpox and enteric fever. (2) Inflammations. — When no specific rash exists, and no distinct history of contagion is suggested, search must be made for signs of inflammation, and although the case may be ad- mitted to a medical ward, the possibility of superficial inflam- mations or abscesses, periostitis, otitis, parotitis, and other glandular inflammations, must never be forgotten, esjDecially in the case of children or those unable to express their sensa- tions. Tonsillitis, quinsy, pharyngeal abscess, scarlatina, and diphtheritic sore throat must specially be remembered in this connection. Pain and its situation usually guide us to these and similar inflammations, and also to articular or muscular rheumatism. Regarding internal inflammations, the impor- tance of examining the chest cannot be overrated, as we often find there the explanation of the febrile disturbance. This must never be neglected. Inflammations of other internal organs usually indicate their existence by pain over the parts, or by changes in the excretions, or by other alterations in the functions, such as paralysis, delirium, etc. A systematic search must be made into the state of all the important organs before arriving at a negative conclusion. Shiverings are common in various febrile diseases, especi- ally at the beginning; but when severe and recurring, the idea of suppuration somewhere is suggested, or the presence of stones in the kidney or gall-bladder, or perhaps embolism and pysemia. Such suppurations may be in parts beyond the reach of our diagnosis, but search must be made for tender regions in the principal organs, and also in the joints, and for pus in the excretions. (3) A miscellaneous grouj:) of diseases having certain rela- 108 SYMPTOMS OF FEBRILE STATE. tionships with the specific fevers and inflammations, but not definitely belonging to either, still remains. It is impossible to enumerate them, but traces of their presence will usually be found on systematic examination of the patient. Care must be taken not to conclude at once that the febrile state is due solely or chiefly to the inflammation which we may thus detect by our examination. For example, bronchitis is an habitual accompaniment of typhus, and pheumonia is common in many fevers. Inflammation or congestion of the kidneys (with albuminuria) is a frequent complication in many com- plaints. It is often diflicult to know whether we have to do with a primary, a secondary, or a mere coincident inflamma- tion ; the date of the illness, and the known characters of the disease, often assist us, and the want of correspondence be- tween the apparently slight extent or severity of the inflam- mation and the intensity of the fever, sometimes leads us to suspect that there is somethiug behind the local inflamma- tion. The temperature in disease is now discussed more or less fully in all systematic works on medicine, and also in treatises on special diseases. — Wunderlich, Medical Thermometry, translated for the New Syden- ham Society, London, 1871 : this work contains a mass of informa- tion as to the general behavior of the temperature, and details and references bearing on special diseases also — Miirchison, The Con- tinued Fevers of Great Britain, 3d edition, by Dr. Cayley, London, 1884. — The pulse is discussed fully in many v, orks on physiology, see especially Landois, Text-book of Human Physiology : translated with additions by Dr. Wm. Stirling, 2 vols., London, 1885. — Byrom Bram- well, Student's Guide to the Examination of the Pulse and the Use of the Sphygmograph, 2d edition, Edinburgh, 1883. — See also Chapter XVI. of this manual, where further information and references regard- ing the sphygmograph may be found. CHAPTER IV. SKIN— HAIE— NAILS— GLANDS— JOINTS— BONES. Cutaneous Eruptions. Eruptions on the skin are sometimes brought prominently under our notice as the chief part of the patient's complaint, or, at least, are so obvious that they caimot be overlooked ; but in other cases we have to search carefully for an eruption of which the patient may be unconscious, or which he may regard as quite trivial and accidental. Most of the cutaneous eruptions serve to indicate the presence of some more or less serious poison in the blood, or of some constitutional affection or tendency to disease. Thus the eruptive fevers present on the skin the evidence of a general disturbance of the whole system. The occurrence of an early or late syphilitic erup- tion likewise reveals a constitutional affection, and the same may be said of scrofulous, and perhaps also at times, of can- cerous diseases of the skin. The pigmentations of pregnancy and Addison's disease, the blotches in scurvy and j^urpura, and the influence of certain medicines in producing eruptions of various kinds, all indicate the same thing. Eczema and psoriasis, from their symmetrical distribution, their tendency to recur, and their association wdth certain other diseases in the patient himself, or in his family, can usually be shown to be much more than mere local diseases. Even parasitic affec- tions of the skin often owe their rapid development and per- sistency to the general state of the health : the vegetable j^ara- sites do not seem to find a suitable nidus in j)erfectly healthy subjects. We must, therefore, always direct our attention to these two great points in the study of cutaneous eruptions — the local condition and the general state. The general derange- ment may manifest itself by changes of which the skin affec- tion is but one out of many ; or the cutaneous disease may be the sole manifestation, or, at least, the chief evidence, of the general disorder. On the other hand, affections of the skin arising from local causes, or, as more frequently hapjoens, aggravated by local influences, may give rise to a general disturbance of the whole system. 10 110 CUTANEOUS ERUPTIONS. For the classification of skin eruptions the most satisfactory and the most solid system would be one based on their causa- tion, rather than on their special forms. Hitherto this has only been possible to a slight extent, as the causes of many eruptions are unknown, and the causes of others are not uni- form, or, perhaps, are complex and indirect. The real cause of eruptions must be kept in view, however, so far as this is possible. It is of the utmost importance, for example, to know whether an eruption is due to iodide of potassium, to sraall2:)0x, to syphilis, or to scabies ; any system which would group together such diverse affections as " papular " or " pus- tular," even although they may all present papules or pus- tules, tends only to mislead. And further, any grouping of skin eruptions based merely on the elementary lesion is ren- dered impossible for any useful purpose, when we find scabies, for example, presenting at different times, or even in diflferent parts at the same time, such diverse lesions as papules, vesi- cles, and pustules ; or when we find eczema at one time pap- ular, at another vesicular, at another pustular, and at another somewhat scaly ; or when we find syphilis assuming nearly every variety of form. Still, as the causes of eruptions are often unknown, and cannot even be suspected by the inexperienced, we avail our- selves of the obvious distinctions afforded by the peculiarities of the lesion; and when nothing more can be done, the student may at least describe the nature of the lesion, the exteut and distribution of the eruption, and the general and local symp- toms associated with it. The Elementary Lesions, indeed, formed the basis on which Willan and Bateman's classification was built; and, although now discarded, like most of the old nosological systems, the facts on which it rested are of great value and are still constantly referred to ; being themselves pioneers in dermatology their groupings form a guide to the beginner, and so they will be indicated here more fully than might seem proper from the standpoint of our present ideas of classi- fication. Erythema is a simple redness of the skin due to hyperiiemia, fading readily on pressure, and not extending to the cellular tissue: there is often oedema, and in one form of disease bear- ing this name the lesion is deeper. (See " E. nodosum," p. 113.) Wheals (pomphi) are well represented by the red and white elevated patches produced by the sting of a nettle, or the bite ELEMENTARY LESIONS. HI of a bug, or even of a flea ; they are usually rapidly formed and quite evanescent: in slight forms the white portions may not appear ; in severer forms they may be complicated with actual blisters. Their presence is usually associated with itch- ing, burning, or tingling sensations. Papuke are pimples of various sizes and forms ; they are circumscribed and solid, but may be very different in their constitution. Vesiculce and bullce differ from each other in size, the former being small blisters and the latter large ones. They may be simple, or they may have divisions so as to be compound. They may present perfectly clear fluid under the epidermis, or they may contain inflammatory products to a variable extent, so as to present all degrees of turbidity — the separate vesicles passing through these various stages ; they may be associated with all degrees of redness of the adjacent skin, or they may be free from this comjilication. Vesicles usually occur in clusters, the grouping and position of which are important in the diagnosis. They may pass on to suppuration, forming pustules, or their contents may dry up, forming crusts. Several vesicles may coalesce, forming large blisters or " blebs." The contents of bullae may be sanious and slight ulcerations may be left on the separation of the crusts. Pustuke may result from the fluid in the vesicles becoming purulent or from the suppuration of a papule — this may arise from irritation or other inflammatory action ; the pus is often formed so rapidly that it may seem to exist from the begin- ning. There is often an inflammatory areola at their base, and this is a point insisted on by some in their classification. When the contents dry up they form crusts or scabs. These are often of a brownish color from the admixture of blood. Squamce or sccdes and pityrmsis. Scales must be distin- guished from thin crusts resulting from dried secretion. Squamse are true scales, without moisture, from the beginning. When the desquamation is very minute the term pityriasis is used. Unfortunately, however, a disease of rare occurrence, " pityriasis rubra," is so named, although characterized by the shedding of large scales or flakes. Tuhercida are little lumps, too large to be classed as pimples or differing from them in other respects. They have only an etymological connection with the tubercle recognized in the pathology of internal affections. They include various cuta- neous and mucous growths of perfectly dissimilar kind. Hemorrhages. Maeulce or stains of the skin are sometimes 112 CUTANEOUS ERUPTIONS. hemorrhagic ; or they may be parasitic ; chemical agents and various constitutional disorders j)i'oduce pigmentary deposits. (See p. 140.) Secondary Changes may result from or be present along with various forms of elementary lesion. Desquamation, although often occurring independently (see " Squamae "), may form the terminal stage of an erythema, or some inflammatory process by Avhich the epidermis has suffered. Crusting is one of the most important secondary changes. Very thin crusts may resemble scales, but careful examina- tion usually shows them to be largely composed of dried secre- tions (in ichthyosis, however, the scales are epithelial). The discharge may be very slight, and may proceed from a sur- face not ulcerated, or it may proceed from an ulcer. When the crusts are dark, this usually points to the presence of a sanious fluid retained in them, and this occurs frequently in syphilis. Lupus and syphilis differ in their tendency to scab- bing — the ulcers in the former usually scabbing slightly, those of the latter often scabbing freely. Limpet-shaped crusts are almost diagnostic of syphilis (rupia). Cup-shaped crusts occur chiefly in the head, com- posed of the parasitic growth termed favus ; they are light yellow in color, and rather brittle. (See pp. 126, 127.) Ulcerations are secondary changes which must be examined and described in reference to their edges, etc., and any atten- dant constitutional disturbance, as in surgical practice. Swelling and infiltration of the skin, the results of the in- flammatory process, are very important points in the diag- nosis of eczema and of erysipelas. They give, in addition to the swelling, a feeling of undue hardness and resistance to the skin. Hardness of the skin constitutes the leading feature of sclero- derma adultorum. The skin feels hard, as if bound down, and it is often cold to the touch ; the comparison has been made to the touching a frozen corpse ; the hardness may be pretty general or it may occur in bands. A circumscribed variety in patches of circular form and pale color, resembling disks of ivory, is described by some under the name of mor- phoea. The form of scleroderma in newborn infants affects the cellular tissue also. It is associated with oedema and with depression of the temperature. In myxoedema the skin feels dry and parchment-like, but the suggestion conveyed is usu- ally that of a drojisy ; it will be referred to under that sec- tion. ELEMENTARY LESIONS. 113 Excoriations, fissures, scars, and atropine lesions are frequently very suggestive, and must be recorded. The glossy skin re- sulting from lesions of the nerves may be mentioned in this connection, and the disfigurations described by Alibert as keloid (or cheloid) resembling hypertrophied scars. ELEMENTAKY LESIONS IN SPECIAL DISEASES. (Will AN and Bateman). Exanthemata: Erythema, Wheals. — Willan and Bateman had an order named " exanthemata " — the word signifying an efflores- cence : this included two of the febrile eruptions rubeola and scarla- tina, and also roseola, urticaria, purpura, and erythema. The erup- tions of the specific fevers are now separated from other forms of skin disease and put into a group by themselves. Purpura is now placed in the class of hemorrhages. Erythema may be symptomatic of adjacent inflammation or due to mechanical or chemical irritants; but it also occurs idiopathically, and some forms occupy an intermediate position. Thus E. intertrigo is due to the fretting of ff>lds of skin against each other, often aggra- vated by the decomposition or fermentation of the secretions. E. Iseve arises from the pressure of dropsical fluid in a part. E. gangrse- nosum may result from pressure, as in an ordinary bedsore, but it may likewise be caused by grave trophic lesions in the nervous system. E. fugax is usually due to digestive disorder. E. nodosum differs somewhat from other forms in presenting nodular exudations as well as redness: these are usually situated over the tibia ; they are often painful and tender: they appear to be frequently manifestations of the rheumatic constitution. The name erythema as a special disease was formerly applied to many cases of the slighter forms of erysipelas. Roseola, or " rose rash," is now usually regarded as an erythema, from which it need not be separated. Wheals constitute the characteristic sign of urticaria or "nettle- rash," both in its acute and chronic forms. This disease is often pro- duced by special articles of diet in certain individuals, as shell-fish, etc. (see p. 124), or at least appears due to errors in digestion, and at times to nervous disturbance. The local irritation of parasites and exposure to the heat of furnaces may also set up this condition. " Fac- titious urticaria" is the name used for the variety produced in certain persons by mechanical irritation : this may be of such a character that the name firmly traced with a pointed instrument, on almost any part of the skin, comes out distinctly in wheals ; these white letters may remain for many minutes. This susceptibility may be lost by the individual in the course of time. PAPULiE. — Willan and Bateman included under this heading strophulus, lichen, and prurigo. The term strophulus is now sup- pressed by many authorities: it is a somewhat vague term applied to eruptions occurring in infants, loosely ascribed to teething, and termed popularly "red gum," " white gum," or " hives." It is not always papular, and seems often to be connected with the sudoriparous appa- 10* 114 CUTANEOUS ERUPTIONS. ratus. When not papular it should be classed with the erytheraata : when papular it need not be separated from lichen. This disease, again, is regarded by many as a form of eczema, in which the exuda- tion takes the form of papules, and so they prefer to name it eczema papulosum or E. lichenoides. Some who admit this, still recognize forms of lichen under the names of L. ruber and L. planus. Prurigo is still much disputed. A special disease described by Hebra under this name is rare in this country; but papular eruptions, with the enlarged papillre irritated and abraded by scratching, are common enough : it is better to call this a " pruriginous eruption " to prevent confusion, and if taken in this sense such an eruption is a valuable in- dication of itching, past or present, and so we find it in scabies, phthiriasis, and urticaria. Vesicul.e and Bullae — Under the former, Willan and Bateman included varicella, vaccinia, herpes, rupia, miliaria, eczema, and aphtha: under the latter, erysipelas, pemphigus, and pompholyx. Our present ideas lead us to separate the specific fevers from ordinary skin disease (see p. 130), and so varicella and vaccinia may be re- moved : erysipelas in its slight forms was spoken of as erythema : in its bad forms it was so often complicated by blisters that it came under the heading of vesiculse : it has, however, really more affinity with the eruptive fevers (see p. 139). Aphthae are now spoken of only or chiefly in connection with little blisters in the mouth and tongue (see Chapter XI., " Tongue "). Miliary vesicles are discussed at page 139. Herpes consists of an eruption of small vesicles arranged in groups on an inflamed base : these run their course, and are not usually suc- ceeded by fresh groups of vesicles : there is generally a feeling of ten- sion and burning ; occasionally neuralgic pains precede or follow the eruption. "Herpes labialis " is common in ordinary colds : it also appears in many cases of pneumonia, and in some forms of urinary irritation and disease. " Herpes prseputialis " appears on the prepuce and a similar eruption may appear on the glans also. " Herpes zos- ter " (shingles, zona) usually girdles the trunk unilaterally, limited pretty strictly by the middle line, both before and behind, but it may affect the thigh, the face, or the arm, following very accurately the cour.>e of certain nerves. It is not infectious, and rarely occurs a second time in a patient. Eczetna is now generally made to include several forms of skin dis- ease which were formerly separated from each other. It is an inflam- matory disease with exudation and infiltration of the skin, associated with a sense of burning or itching, and it tends to the formation of crusts. In the ordinary form there are vesicles (eczema vesiculosum) exuding a clear fluid, which has the property of stiffening linen ; an excoriated, red, and inflamed surface usually remains exposed ; the discharge may dry very rapidly into crusts which ma}' be so thin as to resemble scales. In some cases the moist discharge, if present at all, may almost have escaped attention, redness and scaliness of the skin being the chief features (eczema erythematosum and eczema squamosum). In other cases the plastic exudation may remain below the surface, giving rise to little papules — the lichen of older authors, but termed eczema papulosum or lichenoides by some. Or the exu- dation, either from obvious irritation, or from debility in the subjects, may become purulent, or the secretion of pus may be abundant from ELEMEXTARY LESIONS. 115 the beginning : this, which was formerly called impetigo, is now often named " eczema pustulosum," or " eczema impetiginodes." Eczema is also named from the parts affected, as " E. aurium," etc. ; also from obvious secondary changes " E. fissum," (>r from the cause, as " E. in- tertrigo " from friction. Rupia; see " Ecthyma " under the "Pustulas," for although it may begin as a vesicle with clear fluid, the contents soon become bloody or purulent. The limpet-lil^e crusts in this disease are diagnostic of syphilis. Pe7nphigus is characterized by large blisters, or bullae, varying from the size of a pea to that of an egg, with different degrees of inflamma- tion at their base, and followed sometimes by ulceration. Occasion- ally large thin crusts or scales are formed (" P. foliaceus "), Pompholyx is now merely a synonym for pemphigus. PusTULiE. — It must be remembered that vesicles readily become pustules, and so some diseases may appear to come under both head- ings. Willan and Bateman included under " pustulee," variola, por- rigo, impetigo, scabies, ecthyma. Vai^iola being a specific febrile dis- ease is discussed elsewhere (p. 133). Porrigo was a general term applied to " scald heads," where the hair was matted together with crusts and scabs, arising from inflammation set up, usually in weak subjects and especially in children, and sometimes due to or associated with the irritation of pediculi. Prom what has been said it will ap- pear that this is a pustular eczema. Another form is due to the para- sitic disease, favus, aflfecting the head (see page 127). Impetigo is merged by many into eczema, the terms E. pustulosum, impetiginosum or impetiginodes being applied to it. Some retain the name impetigo for scattered, sejoarate, pustules without much inflam- mation at their base. A form of this disease named I. contagiosa is interesting as being both infectious as regards others, and inoculable in new places in the patient himself. Ecthyma is a name applied, somewhat variously, to large pustules not a2:gregated together, and each one surrounded by an inflamed base. They are said to occur in debilitated subjects apart from syphilis ; but when very distinct they are not unfrequently of this nature, and when they dry up they form the limpet-shell crusts of rupia. Occasionally the pustule of a so- called " ecthyma " is merely due to scabies. Scabies is classed arbitrarily under " pustulte ;" it presents, however, likewise papular and vesicular lesions. Occasionally no distinct erup- tion apart from scratching can be spen, especially if the hands are often in water from the occupation of the patient. It is parasitic, and is now removed to this class. The itch insect or " acarus scabiei " is found at the end of the little furrows characteristic of this disease, and can sometimes be picked out with a needle from this situation for microscopic examination. (See Fig. 23.) These furrows are seen as small white lines, about a quarter of an inch in length at most, chiefly at the sides of the fingers near the clefts; they are usually tortuous ; they are sometimes inflamed, often interrupted by dots, or by vesicles, and are very apt to be destroyed in their appearance by scratching. The presence of the insects sets up violent itching; this leads to scratching and the appearance of a " pruriginous eruption," or to the development of large pustules (so-called ecthyma), or it may be to 116 CUTANEOUS ERUPTIONS. eczema. The distribution of the eruption is ver}^ important in the diagnosis (see p. 119). Squama. — This class included, according to Willan and Bateman, Pityriasis, Psoriasis, Lepra, and Ichth3'osis. Piify^-iasis, or desquamation, occurs after erythema, febrile rashes, and various other affections of the skin, but it is not usual to speak of it under this technical name when it forms only a stage in a disease. "Pityriasis versicolor" is parasitic, and is not properly a squamous disease, although minute scales are sometimes shed. (See Fig. 31.) "Pityriasis rubra acuta" is a rare disease characterized by great redness of the skin and the shedding of large true scales, without moisture and without much infiltration of the skin. Psoriasis and lepra (alphos) are now classed as one disease; the name " lepra" (used by some for true leprosy) was formerly applied to the patches of psoriasis, in which it spread at the circumference (psoriasis circinata) while the centre was healing; the form of a ring was thus assumed. This is a true scaly disease, without moist secre- tions, the scales are white and often glittering, somewhat imbricated and very adherent ; the}' appear on dusky red patches, which are slightly elevated; all degrees of density in the arrangement of scales are found. All parts of the body may be affected ; the extensor sur- faces of the elbows and knees seldom escape in an abundant eruption of simple psoriasis. When it appears on the palms of the hands, or on the soles of the feet alone, it is very often syphilitic. A form of psoriasis, resembling the shape of rupia crusts, has been named "P. rupioides." Ichthyosis. When the skin is dry, harsh, and wrinkled, with thin scales loose at their edges, the term " xeroderma" is sometimes used. When the scales are thicker, more abundant, and mingled with seba- ceous matter, the name " ichthyosis " is applied. It is a chronic dis- ease dating from childhood. TuBERCULA. — The diseases grouped by the old writers under this heading have but little in common. They were Phyma (boil). Ver- ruca (wart), Molloscum, Vitiligo, Acne, Sycosis, Lupus, Elephantiasis, Framboesia. Acne is an inflammatory disease of the sebaceous glands character- ized by pimples or pustules, often arising from " comedones " — small white pimples with a central black speck. "Acne rosacea " affects the nose chiefly ; there are much redness and hypertrophy of the skin with more or less acne. The cutan(ious surface presents dilated vessels ; although often associated with intemperance it frequently exists apart from this. Sycosis, as now recognized, is distinguished as parasitic or non-parasitic; the latter form affects the hair follicles, chiefly on the beard and face, giving rise to pustules, papules, and crusts. The para- sitic form affects the same parts, but the mischief is due to the same kind of parasite as occurs in ringworm. (See Figs. 28-30.) Lupus is an inflammation and ulceration of the skin occurring in scrofulous subjects, and characterized by the presence of new forma- tion. When slight and superficial, without ulceration, it is called " lupus erythematodes." When the deposit forms little swellings, without ulceration, " lupus non exedens " is the term applied ; when ulcerations and cicatrices are present, it is called "lupus exedens;" CLASSIFICATION". 117 even in the other form, however, subcutaneous cicatricial marks may be traced. MoUusciun is a term applied to soft tumors of the skin, one variety is fibrous, " fibrt)ma molluscum ; " another variety, not exceeding a pea in size, is epithelial, "molluscum epitheliale; " this latter is the contagious variety. Elephantiasis is a name applied to two quite different diseases ; ele- phantiasis Arabum is a chronic hypertrophic disease of the skin and subcutaneous connective tissue characterized by enlargement and de- formity of the part affected, accompanied by lymphangitis, swelling, oedema, thickening, induration, pigmentation, and papillary' growth ; elephantiasis Grsecorum (or true leprosy) is an endemic, chronic, malig- nant, constitutional disease, characterized by alterations in the cuta- neous, nerve, and bone structures, resulting in ansesthesia, ulceration, necrosis, general atrophy, and deformity. (Duhring.) True leprosy occurs in the form of masses of infiltration and tubercles (tubercular form), in smooth patches (macular form), and in patches with anaes- thesia (anaesthetic form) ; these forms may occur separately or in com- bination. Framhcesia or yaws is a disease of the West Indies char- acterized among other things by papules or tubercles of the skin; it need only be mentioned here. Vitiligo is an affection of the pigmen- tation, and will be referred to under that heading (p. 142.) A satisfactory classification of skin diseases might be attain- able if the causes were more fully known. As yet, this method is only very partially available. By it the eruptive fevers are separated from other skin affections ; and, indeed, in the following table they have been removed altogether. The parasitic diseases of the skin are likewise separated from others, as they form a natural group by themselves. In the absence of the etiological method the anatomical site of the disease and the nature of the pathological process, so far as it can be known, seem to form the best basis. The table here given is from Dr. Duhring's work on Diseases of the Skin, third edition, Philadelphia, 1882. It is essentially Hebra's classification.

See p. 130.] Distribution of Eruptions. — In examining a cutaneous erwp- tion, it is a great advantage to see the surface of the Avhole body, or as much of it as j)0ssible. Special abundance of the eruption on certain parts, or the s]3ecial exemption of others, affords at times considerable assistance in the diagnosis. We can in this way also detect the symmetrical character of many eruptions, or the essentially local disposition of others — as when the hand or forearms are affected by some irritant en- countered in a trade, or when the eruption is limited to the legs and caused by stockings with aniline or arsenical dyes. Some eruptions, again, follow the course of certain nerves, and in zona we have usually a pretty strict limitation to one-half of the body, the eruption stopj^ing at the middle line both before and behind when the trunk is involved. But in addi- tion to this general view of the surface, special regions must be examined for special eruptions. Of the febrile rashes, some show first on the face (variola and morbilli), but most of them appear first on the trunk, so that we must search the chest, abdomen, and back, and we should also examine the arms at the anterior aspect of the elbows, etc., where the skin is delicate. We look at the extensor surfaces of the elbows and knees particularly in psoriasis ; at the chest and back in syj^hilis ; at the clefts of the fingers in scabies, to see if any little furrows are present with acari at their extremities (see Fig. 23) ; and also at the inside of the thighs, the external genital organs, the mammae, the wrists, ankles, and umbilicus in this affection; the face is almost always exempted. We examine specially the chest, armpits, and between the shoulders for phthiriasis ; over the chest for pityriasis versicolor ; on 120 CUTANEOUS ERUPTIONS. the head for ringworm and faviis : over the shins for erythema nodosum ; on the face and shoulders for acne ; on the cheeks, nose, and ears for lupus, etc. Fig. 23. The itch insect, Acarus scabiei. Female ; ventral aspect. (Drawn by Pr. John Wilson.) The constitutional disturbance and the general symptoms associated with cutaneous eruptions must be carefully inquired into. Pyrexia, headache, and perhaps delirium, pain in the back, sickness, vomiting, or shiverings ; and pain, burning, tingling, and itching in the parts affected are the most im- portant. Intense pyrexia often precedes the appearan<5e of the rash in the eruptive fevers and erysipelas, and (as men- tioned in the chapter on "Pyrexia"), the skin ought to be care- fully examined by good daylight, if possible, for any appear- ance of a rash. The inspection of the skin for a febrile rash should, in the first instance, be made at such a distance (two to three feet) that the general appearance of the surface can be seen, rather tlian any minute alterations in the skin ; these may be subsequently examined if necessary. Pain in the ITCHING. 121 back and vomiting are especially suggestive of smallpox ; in- tense headache of typhus ; sore throat and vomiting of scar- latina ; coryza and bronchial catarrh of measles ; shiverings may occur in the early stage of any of these, and also in erysipelas. But even in those forms of eruptions, more usu- ally called diseases of the skin, there may be much constitu- tional disturbance, with considerable pyrexia and some gastric disorder, as in eczema and urticaria. The intensity of the general symptoms bears a much more distinct relation to the extent of the cutaneous affection in these cases than in the eruptive fevers. Severe neuralgic pains sometimes precede, sometimes follow, the eruption of herpes zoster. Considerable pain is often experienced in eczema, but in such a case the cause is apparent. Itching is an important fact in cutaneous disease. It is seldom very troublesome in the eruptive fevers, although often present to some extent in measles, smallpox, and chickenpox. It is seldom marked in syphilitic eruptions, so that its absence counts for something in the diagnosis. In urticaria, psoriasis, and eczema, itching is often very troublesome. In parasitic diseases it is a very prominent feature, especially in scabies and phthiriasis. The existence of itching can usually be recognized by the presence of a " pruriginous eruption " due to scratching, and the marks of the nails often tell the same story ; this irritation alters the appearance of an eruption very materially, chiefly by causing inflammation. Itching, however, may exist without any eruption. In some of these cases, this may be due to a nervous affection of the skin, as in " pruritus senilis," the itchiness varying much at particular times. Pruri- tus, es|)ecially at the intestinal and genito-urinary orifices, may be symptomatic of pregnancy, or of disease of the womb, stone in the bladder, diabetes, piles, or other affections of the rec- tum. In many cases, especially (although not exclusively) in children, itching at the anus is due to the presence of thread worms ; in them it is often associated with itching at the nose also, as manifested by picking at the nostrils. But this pick- ing occurs also in diarrhoea and other forms of intestinal irritation. Itching is occasionally present to a troublesome extent in jaundice; it is not unfrequently produced by the internal use of opium and morphia in all their forms. Some persons are especially liable to this inconvenience from the use of opium. An itching of the eyelids is one of the indications of the action of arsenic. 11 122 CUTANEOUS ERUPTIONS. Causes of Cutaneous Eruptions. Infection, Medicine, Food. — In inquiring as to the cause of eruptions, we may as- certain the patient's ideas on the subject, or we may interrogate him as to special points in connection with special forms of disease. Injection. — In the group of eruptive fevers we inquire for any similar illnesses in the same family or neighborhood. Some assistance is at times obtained by learning that the patient has formerly had certain sj)ecific fevers, as a second attack in some of these is but rarely met with. (See p. 131.) In suspected erysipelas, we inquire for exposure to this disease in surgical wards, or otherwise ; and for any contact with puer- peral fever or pyaemia, especially if our patients are predis- posed to infection by recent delivery, open sores, etc. In children, and especially in hospital practice, where infection may be present, wounds or oj)en sores predispose to the occur- rence of scarlatina, which may be mistaken for erythema or erysipelas. In syphilitic eruptions Ave may inquire for the history of the original infection in the patient. Sometimes we inquire as to the husband in the case of a suspicious eruption in a married woman ; of course, in doing so care and discretion must be exercised. Or in the case of congenital syphilis we may have to search for the evidence of infection in the parents, and in the brothers and sisters ; in this last variety, the occurrence of abortions before the birth of the patient is often an important indication of syphilis. But in addition to cases of this kind, we can sometimes trace the infection of a patient from second- ary or congenital syphilis. A nurse's arm may be infected from the sores on an infant's anus, or the nipple from the sores on the child's mouth, or vice versa. (See " Syphilitic Eruptions," In impetigo contagiosa the patient may inoculate one part from another by means of scratching, or may communicate the disease to another person. The occupation is im})ortant in connection with cases of suspected glanders, malignant pustule, etc. In parasitic diseases we often gain considerable assistance from the knowledge of their having spread by infection. Thus, if two persons sleep in the same bed, scabies in the one is almost certain to be communicated to the other. This disease is also communicated by infected bedclothes, apart from any direct contact with patients so affected. In ringworm the affection often spreads from the use of ths same hair- INFECTION". 123 brushes, although the patients may not otherwise be much associated : ringworm of the body may appear in those who are attending on children whose heads are affected. In favus the contagion may be derived from some pet animal as well as from a patient. The pediculus pubis is sometimes found in persons of good position from their consorting with prostitutes. Its presence usually gives rise to great itching and irritation of the parts, but does not always do so. This parasite may affect other portions of the body as well as the pubes ; it is found in the axilla, and also on the eyelashes or eyebrows, particularly in the children of the poor : the ova may be found at the roots of the hairs, presenting a definitely roundish con- tour on examination with a hand lens, and so distinguishable from small scabs or crusts which they closely resemble. On pulling out a few hairs they can be examined microscopically on a slide. (See Fig. 24.) The itch insects, and pediculi cor- poris and their ova often continue to act on the patient through the medium of the underclothing and the bedclothes, even after those on the skin have been got rid of. Indeed, the clothes of the patient are the special habitat of the pediculi referred to, which are on this account sometimes named " pediculi vesti- mentorum :" they often lurk in the seams, where they also deposit their ova, and so escape destruction. Certain varieties Fig. 24. Pediculus pubis, or crab louse, with ova adhering to the hair. (Drawn by Dr. John Wilson.) of the same parasitic disease must be borne in mind while searching for the history of infection — thus we have ringworm of the head, of the body, and of the beard. Many cutaneous diseases have been found to be associated with and presumably due to specific microorganisms. The 124 CUTANEOUS EKUPTIONS. bacillus of tubercle and of lepro'sy and the microbes of the eruptive fevers, erpsipelas, and syphilis may be mentioned; but the subject is too complicated, and in some phases of it too uncertain, to demand more as yet than a mere reference to it in such a book as this. Certain medicines and articles of diet are apt to produce cutaneous eruptions. Shell-fish, preserved salmon, cucumbers, walnuts, game, sausages, pickles, spices, even strawberries, and various other articles produce at times an eruption of urticaria or erythema. Some persons, indeed, are particularly liable to this effect from special articles, so that it is almost certain to follow their use ; in others, the effect is less constant. These eruptions sometimes simulate the specific fevers ; the absence of consitutional disturbance in proportion to the rash, and the absence of the special features of the specific fever simulated may sometimes guide us in the discrimination. Of medicines, iodide and bromide of potassium, belladonna and atropine, quinine, salicylic acid and its salts, chloral, sulphur, arsenic, tar, and copaiba may be named as all producing at times cutaneous eruptions ; and the application of carbolic acid as a dressing sometimes determines an eruption of erythema which may simulate scarlet fever. Iodide and bromide of potassium produce pimples (acne), which appear chiefl}^ on the face and shoulders ; occasionall\' the eruption is more distinctly pustular, and has even been mistaken for smallpox. The eiuption is sometimes hemorrhascic. The affection of the mucous membrane of the nose and eyes, and the swelling of the glands be- hind the jaws, sometimes guide us in the recognition of iodism. Belladonna and atropine produce at times a distinct erythema somewhat resembling that of scarlatina; a certain similarity to the eruption of measles is found in some cases. This rash may result from the internal use of the drug (usually in full doses), or from the action of external applications in the form of plasters, especially if excoriations exist on the skin. Dryness of the fauces and more or less dilatation of the pupils are usually present to assist in the recognition of this eruption. Quinine sometimes gives rise toa very pronounced red efflorescence; this effect is not common, and depends on an idiosyncrasy in the patients affected. Chloral often produces a congestion of the skin, and this may as- sume the character in certain cases of patches of redness like scarlatina or urticaria. Salicylic acid and the salicylates also determine patches of erythema and blotches of ecchymosis, which are liable to be further complicated by the effects of profuse sweating Antipyrin, thallin, and some other of the newer antipyretics, pro- duce red rashes at times. EEUPTIONS FEOM MEDICINES. 125 Opium also seems at times to give rise to patches of redness in the skin. Arsenic produces, although but rarely, an eruption somewhat re- sembling eczema, or at least a prominence of the papillae with conges- tion of the skin. In certain cases herpes zoster has appeared to be due to the use of arsenic, and pityriasis rubra has also been known to supervene in connection with its administration. Puffiness and itch- ing of the eyelids, sickness or pains in the bowels, and whiteness of the tongue assist in the recognition of arsenical influence. Local irritation from arsenic may manifest itself by ulcerations of the part affected. Sulphur and tar are said to produce at times an eruption resembling a badly developed eczema, and large doses of turpentine may produce an erythema. Copaiba gives rise in some cases to urticaria of the usual kind, but Fig. 25. fMVf/pilfiWf^ \ ' i' / "11 Wli imm O O " O Oo O O o O 3 ^ O 00 '^ Root of hair affected with favus, showing the spores : 250 diameters.

See p. 127. 11* 126 CUTANEOUS ERUPTIONS. the white parts of the wheals may be absent, so that the rash is only red ; at times this eruption closely simulates measles in its general appearance, but it does not specially affect the face, and is not asso- ciated with catarrh. Copaiba is so much used in the treatment of gonorrhoea that when we see an eruption associated with this disease we should always suspect the action of this drug. Cubebs has also been known to produce a similar rash. Nitrate of silver administered internally for some time may cause a dark discoloration of the skin aflfecting the parts exposed to the light. In addition to the above, a great many remedies produce eruptions from their local action if applied to the skin. Affections of the Hair: Examination of Vegetable Parasites. — Absence of the hair is termed "alopecia." This Fig. 26. Portion of favus crust, showing the mycelium, with septate cellular tubes, moniliforiu rows of cells, and free spores : 250 diameters. (Drawn ))y Dr. .John Wilson.) is sometimes, althoiigli very rarely, almost universal, affecting the face and head, tlie piibes, eyebrows, and even the minute hairs in every part of the body (alopecia universalis). The baldness of advancing years, and premature baldness, which is often hereditary, need only be mentioned. The loss of the AFFECTIONS OF THE HAIR. 127 hair in syphilis, and after fevers and erysipelas, is usually only temporary, but sometimes a partial baldness becomes permanent in this way. Limited patches of baldness on the scalp, and more rarely of the beard, assuming a circular form, or at least with circular margins, are termed " alopecia areata;" in this affection the hair is quite absent in the fully developed affection, the skin being quite smooth and even glossy. It is supposed by some to be due to a parasite (Microsporon Audouini), but it is regarded now by most authorities as a neurosis. In ringworm and favus the hairs are not quite absent, the bald patches present some stunted hairs. In favus the hairs are found, in a typical case, to pierce a cup-shaped yellow crust near its centre ; this sulphur-colored crust fre- quently has a mouse-like odor ; patches of red, irritable, shining skin may be found where the hair follicles have been destroyed. The parasite in favus is named Achorion Schdnleinii. In ringworm the hairs resemble stubble, being dry and withered or sometimes half broken ; the brittle hairs break Fig. 27.

The parasite in riDgworm is named Tinea trichophytina or Tricophyton tonsurans. In examining hairs, scales, crusts, etc., for vegetable para- sites certain precautions should be used. A diseased hair- should, of course, be selected, if possible, for the examination ; we judge by its stunted, brittle appearance, and by its loose- ness on extraction. In examining scales, too much of them may render the specimen rather opaque ; the scales and even the hairs may have to be dissected by needles to expose the j^arasitic growths. Digestion in a solution of caustic potash renders the specimen more transparent. In certain cases it is desirable to get rid of the fat about the hair or the scales, as the small oil globules simulate vegetable spores. To remove these, sulphuric ether may be used, either before the applica- tion of the potash or after it, the specimen being dried from the one before the other is applied. In examining for vegetable parasites, we search for sj)ores Fro. 20. Downy hairs found in ringworm after treatment by blistering. The upper hair shows the point sijlit into filaments by the action of the parasite; the lower shows the shaft split up in the same way : 250 diametei's. (Drawn by Dr. John Wilson.) (conidia) ; these are small globular bodies, usually arranged in groups or clusters, or in rows ; when rows of these exist they may give off branches (sporidia). Branching tubes, often of a very fine thread-like structure, constitute the " mycelium " or " thallus " of these vegetable growths ; they vary much in diameter, and often interlace in the most intricate manner. These growths are not destroyed by caustic potash, alcohol, ether, or chloroform ; in doubtful cases, where fat, blood, or pus may simulate spores, these reagents may be absolutely RINGWORM Fig. 30. 129 ^\Sm8i^ o ooRo Hairs from a case of Tinea ton.'nirans, or ringworm, showing the parasite - Tinea trivo- phytina.

Foreign bodies containing vegetable fibres may sometimes simulate mycelium, but care in selecting the specimen and the absence of branching usually prevent error. The various jieculiarities in the parasitic growths and in the hairs may be seen in the drawings of favus and ringworm. (See Figs. 25 to 30, with the descrij)- tive notes.) Febrile Rashes. Certain specific febrile diseases are characterized by the appearance of a cutaneous eruption. They are typhus, enteric, and scarlet fever, measles, smallpox, and cliickenpox ; ery- sipelas may also be included in this list for our present pur- pose. In addition to these, cutaneous eruptions, of a varied and uncertain character, are occasionally seen in relapsing fever, in diphtheria, and in cerebro-spinal meningitis ; some have alleged the occasional presence of an eruption in pneu- monia and acute tuberculosis, but this must still be reckoned doubtful. In all of these diseases the eruption is preceded by constitutional disturbance and the general signs of fever, especially by pyrexia, shiverings, sickness, and vomiting, headache, pain in the back, and general malaise, delirium, and great nervous disturbance : convulsions may be met with in children. Certain of these symptoms are more pronounced in some fevers than in others, and several of them may be almost absent in a given case. In addition to those which may be regarded as more or less common to all, special symp- toms are found in special fevers : as the sore throat of scar- latina and diphtheria, the bronchial catarrh and coryza of measles, and the diarrhoea of enteric fever. The history of infection or the presumption of immunity in the individual from previous attacks of special fevers sometimes guides our diagnosis. The date at which the rash appears, or its absence at a given time, constitutes an important element in the dif- ferential diagnosis. But in considering the following dates some allowance must be made for uncertainty in fixing the correct date of the illness ; for a slight variation from the average date of the eruption ; and also for the occasional delay of the eruption quite beyond its usual term, or even for its non-appearance, its suppression, or its fugitive character (especially in malignant scarlatina). Sul)jcet to these qualifications, which are indicated more INCUBATION" OF FEVERS. 131 fully in the remarks on the eruj^tious in detail, the following dates may be given : Date of Appearance of the Febrile Rashes after THE First Signs of Illness. Scarlatina rash appears on the first or second day. Smallpox appears on the third day. Measles appears on the fourth day. Typhus appears on the fifth day. Enteric fever appears on the seventh day or later. Chickenpox usually shows itself within the first day after the con- stitutional disturbance, but this is often so slight as not to be clearly marked. German measles (red measles, rotheln, roseola, rosalia, etc.) may appear on the second, third, or fourth day, or the rash may be amongst the ver}^ first symptoms recognized. Erysipelas varies considerably as to the date of its appearance on the skin, but may usually be detected on the day after shiverings or other febrile disturbances have appeared. Occasionally, however, the rash is delayed or suppressed, or appears only as fugitive patches which readily escape notice, just as happens in certain cases of scar- latina. PERIOD OF INCUBATION. This is not always uniform, and in many cases cannot be determined with accuracy, as the infection may linger in the clothing or other materials (fomites), for some time after the more obvious exposure of the person to the disease. Scarlatina: incubation period varies from a few hours to eight or ten days ; apparent prolongation for a longer period (which is not unusual) can often be explained more naturally on the supposition of infection through clothing and the like. Sm,all2iox : thirteen or fourteen days. Varicella, or chickenpox : ten to fourteen days. Measles: usually about a fortnight; said to be seven days when inoculated from nasal mucus ; variation in extreme from seven to twenty-one days. German 'measles (Rotheln) : varies from seven to fourteen days. Typhus fever : varies from a single day to nearly three weeks ; usually about seven to fourteen days. Enteric fever : about two or three weeks. Erysipelas : period very uncertain ; probably short, as a rule. LIABILITY TO SECOND ATTACKS. Scarlatina: an indubitable second attack very rare, but not un- known ; dubious illnesses erroneously called scarlet fever may account for most of the so-called second attacks. Varicella, or chickenpox : a second attack extremely rare. Typhus fever : a second attack extremely rare, but not unknown ; the common confusion between typhus and typhoid (enteric) fever must be remembered in judging of the history of patients. 182 CUTANEOUS ERUPTIONS. SynaUpo.v : a second attack by no means rare ; errors in ttie diagnosis from other forms of pustular eruptions are quite possible. Traces of former attacks are usualU^ visible. Measles: a second attack, as alleged, is very common ; possibly this may arise from there being two forms of measles with quite dis- tinct powers of infection (see " Rotheln" or " German measles "). Eiiteric fever : one attack does not seem to afford much if any pro- tection from a second (relapses are also very common). E7'ysipelas : one attack seems rather to predispose to a second than to afford exemption. The scarlatina rash, when well developed, presents a bright uniform redness very similar to that of a boiled lobster. In the early stage a multitude of minute red points can often be recognized, but these soon coalesce and present a uniform redness. The rash usually appears first on the chest, abdo- men, neck, or back. It sometimes conies out first on the legs. It disappears on pressure — pressure with the fingers, or strokes with the nails leaving white marks. In the progress of the rash it extends from the trunk to the arms and legs, and frequently can be seen to have, as it were, fresh developments, fading in one part while extending to others, and varying in brightness at different times. Toward the end of the first week it usually begins to fade, and disappears as a rule before the tenth or twelfth day. After the rash fades desquamation begins, and this is usually in proportion to the severity of the rash. (Desquamation, arthritic pains, and albuminous urine often point to the scarlatinal nature of a rash previously reo-arded as triflino:.) At times the scarlatina rash is so faint and evanescent as to elude recognition. Examination by good daylight is very important in such cases. In malignant forms the rash is sometimes very dusky or almost petechial ; in other cases it is patchy and shifting in its appearance. In the puerperal form the rash may not be noticeable, or may only be traceable as slight patches on the hands or elsewhere. The rashes most likely to be mistaken for scarlatina are the belladonna rash, the eruption of urticaria when the white parts of the wheals are absent, and some forms of erythema. This last disease has probably been the real affection in some ])atients said to have been repeatedly attacked by scarlatina. In young infants a transient erythema or roseola sometimes simulates scarlatina ; its repetition and the absence of sore throat serve to distinguish it. The bright redness and the copious desquamation in "Pityriasis rubra acuta" have some- times been mistiikcn for scarlet fever. In "German measles," the rash often resem])les scarlatina so closely that it cannot SMALLPOX. 133 be discriminated in the later stage of the eruption. In all cases of doubtful rash, the character of the tongue, and especi- ally the presence of sore throat, with patches on the tonsils or ulcerations, constitute most important guides ; indeed, ivhen the rash is copious we must have great hesitation in admitting its scarlatinal nature if there be no sore throat. Constitutional disturbance and j)yrexia are present in all degrees in scarla- tina, and sometimes are so slight as to evade our recognition. Subsequent desquamation or peeling of the skin about the fingers or elsewhere, and the occurrence of albuminuria about the tenth to the twentieth day, often clear up the nature of a doubtful rash. A previous attack of scarlatina is not an absolute protection from this disease, but it is rare to find clear evidence of a second attack. There is great variety in the predisposition to take scarlet fever. A person may have been exposed to the disease, even in the same bed, and escape the infection, but may be attacked on much slighter exposure later on. An eruption of roseola, resembling, to some extent, that of scarlatina, sometimes appears before the smallpox rash comes out. It is likewise found after vaccination, and revaccina- tion. A similar redness is noticed occasionally in enteric fever in its early stage, and in connection with relapses. (Roseola exanthematica.) The smallpox eruption (variola) appears as a rule on the third day, but sometimes on the second, fourth, or fifth. In serious cases it appears early, as a rule. The stage of incuba- tion is usually a fortnight. Occasionally a " roseola " precedes the true smallpox eruption, giving rise to the idea of scarla- tina. The appearance of the smallj)ox rash is usually associ- ated with a distinct, and often Avith a very great diminution of the previous febrile disturbance (see Fig. 10;, unless, in- deed, in the graver forms, where the decline may be scarcely noticeable. The eruption appears first on the face and neck in most cases, but sometimes on the palate, the wrists, or the trunk ; it spreads to the other parts in a day or two. At the beginning the eruption consists of red papules : these can be felt to be hard, like small shot embedded under the skin. The pimples in the course of a day or two become vesicular, but the contents rapidly become purulent, and an area of in- flammation (areola) appears around the pustules ; consider- able swelling and itching of the skin usually accompany a severe eruption. When the pustules run into one another they are called " confluent," when they remain quite separate 12 134 CUTANEOUS ERUPTIONS. the term " discrete " is applied. A depression in the centre of the pustule usually becomes apparent soon after it is formed, but this " umbilication," as it is called, does not always occur, and sometimes it becomes effaced. Each pustule is multi- locular. The " maturation " of the pustule occurs about the ninth day. As the pustules shrink scabs are formed, and when these separate dark colored stains remain for a time. Depressed marks or " pits " are left in proportion to the sever- ity of the case. The smallpox papules may often be felt in the roof of the mouth, the soft palate, and the tongue ; the eruption occurs, also, in other parts of the mucous surface. In severe cases hemorrhages are seen under the skin as well as inside the pustules. Hemorrhages from the mucous mem- branes and a few papules may be the only visible manifesta- tion of hemorrhagic smallj)Ox. In smallpox modified by vaccination (varioloid), the erup- tion is usually less abundant and is not often confluent. The constitutional disturbance may be considerable or but slight. The eruption may closely resemble that of unmodified small- pox, or it may consist simply of a few abortive pimples with- out any proper vesication or pustulation. Vaccination and re-vaccination lessen the chance of contracting smalljjox very materially. (For diagnosis see below.) Chickenjwx (varicella) resembles smallpox in many respects, but it is essentially vesicular, although it may be j^ustular where irritated ; the hard nodular papules are usually absent. The eruj^tion has no sj^ecial preference for the face, but rather for the shoulders, back, and hairy scalp. The vesicles are preceded by an eruption of red spots, but slightly elevated : the lesion is altogether much more superficial than in small- pox and there are no dissepiments in the vesicles. The erup- tion usually appears within twenty-four hours of the preceding disturbance, if there has been any, but as a rule this is slight. A succession of separate crops of the eruption can often be recognized from their being present in different stages. It is an infectious disease, but usually attacks children only. It is not prevented by vaccination, and does not protect the patient from smallpox. The chief difficulties in the diagnosis of smalljwx arise in the slighter forms, occurring in vaccinated persons, as the few })imples which appear may be regarded as trivial, especially if the patient be subject to acne. In some forms of measles a certain resemblance to smallpox arises from the si)Ots in the early stage being unusually hard, or from the dusky hue and GERMAN MEASLES EASH. 135 hemorrhagic tendency of the rash. In some forms of small- pox also, the rash resembles measles from a transient efflores- cence forming a basis for a subsequent papular eruption. The presence or absence of the shot-like papules peculiar to small- pox and the subsequent course usually guide us aright. A pustular eruption in syphilis sometimes resembles smallpox very closely, especially when it appears after great general disturbance. An eruption from iodide of potassium, usually papular but sometimes pustular, occasionally simulates small- pox. The presence of the loculi and the umbilication in smallpox pustules are often useful in guiding us. Chickenpox, although usually differentiated easily enough from smallpox, is sometimes quite undistinguishable from the modified form of the disease, at least in isolated cases. The measles eruption (rubeola, morbilli) appears usually on the fourth day, and corresponds with an exacerbation of the prodromal fever. (See Fig. 11.) It appears almost always on the face first. It consists of elevated red spots or patches, which tend to assume a circular or crescentic outline. At first the skin between the spots is not red, but it usually becomes so in some parts, and the elevated patches often coa- lesce. The eruption spreads from the face to the trunk, and from the trunk to the limbs. It may be three or four days before the rash attains its maximum extent, and it may be fading in some parts as others become affected. The rash fades on pressure in ordinary cases, but in grave forms the eruption may be dusky and even petechial. Considerable swelling of the skin of the face is usually obvious in measles. The coincident phenomena generally guide us aright in the early stage or in doubtful cases ; running at the nose and eyes, sneezing, cough, and bronchitic rales are very common. In cases with a receding or undeveloped rash we have, at times, grave nervous disturbance. The eruptions most likely to be confounded with measles are copaiba rash, typhus, roseola, and hemorrhagic smallpox in the early stage. The German measles rash (rubeola notha, roseola, rotheln, rosalia) resembles at times measles and at times scarlatina, or it may begin with a resemblance to measles and become very like scarlatina. It does not show such a preference for the face as measles, and the crescentic character is less marked. The rash may be very abundant with but a moderate tempera- ture (102^ or 103° F.). It usually appears about the same time after the beginning of the febrile disturbance as a scar- 186 CUTANEOUS EKUPTIONS. latina rash, but may be somewhat later. There may be slight sore throat, but seldom any distinct patches or ulceration. There may be slight bronchial catarrh. The symptoms, like the rash, present a combination of the peculiarities of scarla- tina and measles, but the whole disease is usually mild and of short duration, and the rash disappears in three or four days. The disease is communicated by a special infection, evidently different from that of either scarlatina or measles, and a pre- vious attack of one or both of these diseases does not protect the patient from German measles. It is probable that this disease is often involved in the not uncommon reports of chil- dren having had measles twice. This form of eruption is sometimes confused with a copious typhus rash, as well as with scarlatina and measles. It also resembles the copaiba rash. The typhis rash appears from the fourth to the seventh day, usually about the fifth day from the first signs of acute illness. The rash is but rarely absent in typhus fever, except in mild attacks in young patients, and its extent and depth bear a dis- tinct relation to the severity of the case. It is, however, very apt to be overlooked by the inexperienced, owing to its delicate tint, to its brief duration in some cases, or to the absence of good daylight for the examination. Sometimes the inexperi- enced look too closely into the skin, and so fail to see the mottled rash, which becomes more evident when looked at from a little distance. A dirty condition of the skin, and the presence of flea-bites, also render the recognition of a typhus rash more difficult. Flea-bites, indeed, present a considerable resemblance to typhus spots in certain stages, but the central minute dark dot or bite can often be recognized; flea-bites also are generally aggregated on covered parts of the body, typhus spots are often seen on the back of the hands. Before the rash appears in a definite form there is frequently a con- gestion or redness of the skin, well shown on pressing with the fingers, especially over the back, the chest, and the belly. This condition is associated with suflfusion of the eyes, and a dingy complexion. There are two elements in the typhus rash, which, however, are not always both present — these are definite spots and a more general m(^ttling. The spots, when seen immediately after their appearance, are usually red, perhai)S slightly elevated, and they disap))car on pressure. They vary in size up to about a quarter of an inch in diameter, and are irregular in their form. In a day or so they become dirty looking, and ENTERIC FEVER ERUPTION. 137 cease to disappear on pressure. Fresh spots may appear dur- ing the first two or three days of the eruption, but these are sujieradded to the first ones, which remain. The spots ulti- mately become bluish or reddish-brown in color, and distinct petechise or subcutaneous hemorrhages are not unfrequently developed in the typhus spots. In addition to the distinct spots just described, we usually have soon after they appear a general mottling of the skin, as if there were a "subcuticular" eruption of minute spots. This, indeed, may be the only eruption visible in certain cases, especially in the mild forms. This mottling requires a good light for its observation, and the chest and abdomen should be well bared for the examina- tion ; pressure of the fingers is useful in ascertaining the pres- ence of this rash. The term " mulberry rash " has been used as descriptive of the general appearance of the typhus erup- tion. The parts on which the eruption first appears are the trunk, more especially on the front, the parts about the front of the shoulders, and sometimes even the arms and hands. The legs, and particularly the face, are less affected, but when the rash is copious the distribution may be very general. The rash persists for about a week after its appearance, fading somewhat as improvement begins, or becoming blue, dark, or petechial as death approaches, and the spots continue to be visible on the dead body if the rash has existed for some time. A second attack of genuine typhus is very rare, but owing to the frequent confusion of enteric fever, and perhaps pneu- monia, with this disease, the mere fact of a former attack being alleged cannot be much relied on, but special inquiries as to the place in which the illness occurred, and as to its symptoms, may clear up the doubts. The eruptions most likely to be confused with typhus by the inexperienced are those of measles, German measles, and flea-bites. A rash somewhat resembling that of typhus ap- pears occasionally in relapsing fever. A much more common error, however, consists in overlooking the presence of the rash altogether. The enteric fever eruption is almost never very obtrusive, and so it is seldom noticed by the public; as a rule, it requires to be carefully looked for. It appears chiefly on the trunk, and especially on the abdomen, but an examination of the back sometimes discloses the only spots visible. The eruption con- sists of small circular rose-colored papules (lenticular spots) jiot exceeding one-eighth of an inch in diameter; they are 138 CUTANEOUS ERUPTIONS. slightly but distinctly elevated ; they fade, or almost dis- appear on gentle pressure, and they fade in this Avay so long as they last, differing in this respect from the typhus spots. The number of these spots in a case of enteric fever varies exceedingly ; in some cases only two or three such papules can be found on a careful search of the whole body, and in others there may be twenty or thirty on the abdomen. The abundance of the eruption bears no relation to the severity of the case. Some cases present only one or two spots, although carefully examined every day, and not very unfrequently no eruption can be found at all. The spots appear in successive crops, each crop lasting about four or five days before disap- pearing. This feature of a succession of rose spots is most important in the diagnosis. It can be demonstrated by mark- ing with ink all the spots visible to-day, say with a circle, those which appear to-morrow with a triangle, and those which appear next with a square ; by the time these last appear, the first marks will be found empty or containing only the merest trace of a spot. This eruption seldom appears before the seventh day of the fever, but its appearance is often much later. Fresh eruptions may continue to appear until con- valescence is fairly established, and they may appear during a relapse, even although none were present in the first attack. In addition to those rose-colored lenticular spots, very deli- cate blue patches (taches bleuatres) have been described in this fever as appearing on the abdomen, and an eruption of sudainina is regarded by some as very characteristic of this disease, but these last are found in various other affections. (See "Sudamina," p. 139.) The chief sources of fallacy in connection with the erup- tion of enteric fever are: (1) An imperfect examination of the trunk of the body. (2) Mistaking the presence of acci- dental pimples for true " rose spots ; " the marking and subse- quent observation of these bring out their difference. (3) Typhus spots when freshly out sometimes resemble "rose spots," as they fade on pressure at this time, but become per- sistent after a day or two. There is no mottling between the enteric rose spots. (4) An abundant eruption of " rose spots " has sometimes been confounded with a typhus rash. (Enteric fever is contagious, no doubt, chiefly through the intestinal excretions ; it fre(iuently afl^ects various inmates of a house about the same time, and arises very often from bad drains or leaking soil pipes and contaminated water supply. This may operate in poisoning milk, which seems to be a very EEYSIPELAS. 139 suitable vehicle for the propagation of the poison. A pre- vious attack does not seem to afford much, if any, protection from a second. Inquiry into these matters may aid the diag- nosis.) Sudamina or miliary vesicles are minute accumulations of the secretion from the sweat ducts, arising from obstruction to their openings. They vary in size, but are seldom larger than a pin-head. They can be felt as giving a roughness to the surface and can be seen in good light as glittering points. Their contents are usually clear ; occasionally there is evi- dence of inflammatory action in their contents being opaque and their bases inflamed. This latter condition has been separated from sudamina by some, and named " miliaria." Sudamina are found in various diseases characterized by much sweating, and have no specific significance, although formerly they Avere regarded in this light. They are common in enteric fever, acute rheumatism, phthisis, and after child- birth. Erysipelas is characterized by redness of the skin, the in- flammation has a deeper seat than in erythema, and there is usually very considerable swelling and elevation of the aflfected part. The redness is usually pretty sharply defined by a line bounding the part aflected, and it extends, as a rule, in a continuous way from one part to another. Vesication is not uncommon in erysipelas if severe, and even the deeper subcu- taneous tissue may be involved in the more serious forms (phlegmonous erysipelas) which are met with in surgical prac- tice. Erysipelas often extends from wounds or sores, especially when it arises from infection ; but it may be idiopathic, and it seems at times to arise from direct exposure of the part to cold. In medical i^ractice it is usually found attacking the head and face, causing much swelling of the loose tissues about the eyes and nose. Or it may attack a limb, or begin- ning in one leg it may spread up the thigh, and crossing over come down the other leg. It .occurs in newly born children, spreading sometimes from an unhealthy umbilicus, but it may appear in older children also, apart from any open sore. It may attack puerperal women, who are specially liable to such infection, and in some cases of undoubted erysipelas no rash may be visible ; these attacks are usually called puerperal fever. Sometimes in grave forms of erysipelas the patches of redness are irregular and fleeting, readily esca2:)ing notice. In connection with extreme dropsy of the legs, whether the skin 140 CUTANEOUS EKUPTIONS. gives way or is punctured, and sometimes aj^art from any oozing, erysipelas often forms a grave complication. Staining, Pigmentation, and Discoloration of THE Skin. Subcutaneous hemorrhages are recognized by their being unaffected on pressure. When small, the words " petechife " or " ecchymoses " are used : when large, the term " vibices " is sometimes applied. These hemorrhages are found in typhus fever, in smallpox, in purpura, in scurvy, in diseases of the liver and sj^leen, and in the terminal stage of dropsy and other exhausting diseases. We must examine for any history of hemorrhage from the nose, gums, or bowels, in cases of .purpura or of the hemorrhagic diathesis ; and we may some- times find submucous hemorrhages in the mouth. Purpura also occurs in connection with rheumatic affections of the joints. In sus^^ected scurvy we inquire for a history of de- privation of vegetables and milk ; this may readily occur in laborers who often live on tea and bacon and bread. The presence of spongy gums and fetid breath, and the existence of pain and hardness near the hemorrhagic patches, especially in the calf, usually guide us aright. In disease of the liver, leukaemia, etc., the spots of hemorrhage seem to be due to a depraved state of the blood. In typhus fever, smallpox, and measles, subcutaneous hemorrhage is an indication of the gravity of the attack. (See, also, Chapter IX., " Hemor- rhages.") Port-ioine stains, ncevi, moles, etc., need only be mentioned here. Tlieir existence since childhood and their general appearance usually prevent any misconception. Discoloration of the skin sometimes results from external agencies, as the application of iodine or nitrate of silver. Frequently repeated poulticing and blistering may likewise give rise to a dark mottling or pigmentation of the skin. On the legs, especially of old people, but also in some others, we often find considerable darkening and mottling from the patients sitting much with their legs near the fire. Of medicines administered internally, nitrate of silver may be mentioned as giving rise to a dark l)luish discoloration of those parts of the skin exposed to the liglit. This is a rare accident nowadays, but with such an alteration in color, especi- ally in one subject to epileptic fits, we must inquire whether this remedy had been used. PITYEIASIS VERSICOLOR. 141 The yellow tinge of jaundice is described elsewhere, and some of the conditions most likely to be confounded with it are there referred to. (See Chapter XII.) Associated some- times with jaundice, but also occurring independently of it, we have at times localized yellow patches, chiefly about the eyelids, but sometimes elsewhere (xanthelasma) ; occasionally the yellow discolorations are associated with distinct firm tumors of small size occurring in various parts (xanthoma). Chlorosis, syphilis, malarial fevers, and cancers may all pro- duce an unhealthy color and complexion. In phthisis, also, we sometimes see considerable pigmentation about the cheek- bones, and around the orbits. Great exposure to the air and weather, associated with un- cleanliness, gives rise to a darkening of the skin with brownish spots and freckles, and sometimes a more general and uniform discoloration (vagabondismus). Sailors and others exposed to tropical climates have frequently a swarthy look, and the influence of race must not be forgotten. In pityriasis versicolor there are defined patches of brownish discoloration, with minute scales, situated usually on the chest Fig. 31. Microspor on furfur, the vegetable parasite of pityriasis versicolor. Drawn by Dr. John Wilson. (Dr. M' Call Anderson.) or at least on the trunk ; the parasitic nature of this eruption can be demonstrated by scraping ofl" a few scales, digesting in liquor potassse, and examining by the microscope. The branch- ing growths of the parasite and the aggregation of spores in bunches are shown in the diagram (Fig. 31;. 142 CUTANEOUS ERUPTION'S. Pregnancy is very often characterized by considerable pig- mentation. It is chiefly marked around the nipple, about the linea alba, and on the face. In uterine tumors, and in other forms of uterine disease, there are often distinct brownish patches on the face, chiefly on the brow, but other parts may also be aflected (chloasma uterinum). In Addison's disease, the pigmentation affects chiefly the face, the exposed part of the neck, the backs of the hands, the axillary and umbilical regions, the genitals, and the inner aspect of the thighs. This discoloration, described as " bronzed skin," resembles the tint of a mulatto, but in some parts the discoloration is darker or almost black. In many cases, con- siderable assistance is experienced by finding brownish stains or black streaks on the buccal mucous membrane and on the tongue and the nipples, although these also may occur in other conditions. The constitutional symptoms associated with the pigmentation in Addison's disease are those of asthenia rather than of emaciation, combined wdth great feebleness of the mus- cles, including the heart itself. Pains in the back and vomit- ing are not uncommon. The disease is often complicated with pulmonary phthisis, or disease of the vertebrae, but the diag- nosis can be most safely arrived at when the prostration and discoloration seem otherwise inexplicable. It is commonest in young male adults ; greater care is required in the diag- nosis in the case of women, and especially if there be any uterine irregularity. The presence of hepatic or renal disease ought also to make us more guarded in our diagnosis in cases of bronzing. White patches of skin may result from cicatrices of all kinds. White streaks are seen in connection with atrophic lesions of the skin, which may be associated with evidence of atrophy or defective formation elsewhere. White vertical lines on the abdominal walls are found habitually in women who have borne children ; they sometimes guide us in forming an opinion as to this fact. They arise from previous disten- tion : similar streaks are found in persons of both sexes and in children, in connection with former dropsical swellings of the belly. White patches from simple absence of pigment in the skin are named vitiligo or leucoderma : around the margin of the w'hite patch there is an increase or deepening of the natural color of the skin. Absence of pigment in the skiiii, ]\a,{r, and choroid constitutes albinism. SYPHILITIC ERUPTIOKS. 143 Syphilitic Eruptions. Syphilitic eruptions assume nearly every variety of appear- ance found in disease of the skin. It is of more importance to recognize an eruj^tion as syphilitic than to define its special form. The following points for such a discrimination are given by Dr. Tilbury Fox : 1. Previous syphilitic infection, as evidenced by the history, by cicatrices of the primary sores, etc. 2. The symmetry of syphilitic eruptions. 8. Their so-called " copper color ; " dull red at first, becoming reddish yellow-brown. 4. A tendency to circular form of the patches. 5. The scales when present are very light and small. 6. The crusts are thick, greenish, or black, and adhere firmly ; vesicles are flat, and do not rujoture readily ; ulceration is common, the surface ashy gray, and the edges sharp. 7. Pain and itching in the parts are not usually troublesome. 8, Polymorphism ; papules, pustules, and tubercles coexist in the same subject, or one form of eruption gradually assumes the character of another. As to the different periods of syphilitic eruptions he gives the following chart : 1st period — Syphilitic fever, with transient hypersemia of the skin, giving rise to roseola, etc. (about the same time as the sore throat — a few weeks after infection). 2d period — Hyj^ersemia and infiltration about the seba- ceous glands — syphilitic acne. Hypersemia and deposit in the hair follicles, syphilitic lichen. In the derma — papular, and tubercular, squa- mous and pustular syphilis. About the nerves — syphilitic herpes and pem- phigus. 3d period — Characterized by changes in preexisting syphi- litic formations which lead to syphilitic ulceration, exos- tosis, etc. In congenital syphilis we look for mucous tubercles at the anus or mouth, red patches or pustules on the buttocks, ankles, or hands, subacute onychia, fissures at the lips ; a history of " snuffles " at birth, and the presence of notched teeth or of old keratitis or nervous deafness, are important. 144 NAILS — GLANDS. Affections of the Nails. Affections of the nails sometimes serve to indicate constitu- tional disorders ; there are also, of course, local affections of the parts. Carving of the nails is observed along with a clubbed shape of the finger-ends, in cases of phthisis ; sometimes the curv- ing exists without any of the clubbing referred to. This deformity is not limited to phthisis, but is found in various chronic states tending to atrophy. It may be found in cardiac and aneurismal disease, and in the latter is sometimes on one side only. Atrophy of the nails, shown by much curving, yellowish- brown discoloration, cracking, etc., may result from lesions of the nerves, or from disease of the spinal cord, and are found at times even in hemiplegia. Cases are reported of shedding of the toe-nails repeatedly in locomotor ataxy. Transverse white marks, or thinned portions in the nails, are sometimes clearly seen after serious illnesses, such as fevers, and we may occasionally avail ourselves of them in checking the history or the dates supplied by a patient. A mark of this kind half way up the nail may be reckoned as indicating an illness three or four months previously. The nails are sometimes shed in pityriasis rubra, and in severe eczema affecting their neighborhood. In psoriasis and pityriasis rubra, the nails are often affected, becoming dingy, thickened, curved, grooved, and dirty looking. Onychia, inflammation of the matrix of the nail with sup- puration beneath it, and loosening of its attachments, is occa- sionally due to syphilitic disease. Strumous disease may also determine inflammation of the nails. Parasitic diseases some- times affect the nails (favus and ringworm). GiANDULAR Affections. Affections of the lymphatic glands afford many indications of general constitutional states. They are often, however, merely dependent on local irritation. Thus a sore on the foot or leg, perhaps of a trivial nature, may by the strain of walk- ing give rise to enlargement and tenderness in the femoral glands ; the anatomical relationship of the lymphatics serves to indicate the connection of these with the leg, instead of the genital organs as might at first be supposed. In the neck, also, the jwsterior cervical glands may be enlarged from the GLANDULAE AFFECTIONS. 145 irritation of an eczema of the scalp, past or present, and not as the result of constitutional syphilis. A chain of small hard glands in this situation, however, constitutes an impor- tant indication of eonstitutional syphilis, in the absence of any- superficial cause for their enlargement. The inguinal glands are often enlarged, and sometimes proceed to suppuration, from the irritation of a gonorrhoea, or of a soft chancre on the penis; indeed, the history of suppurating buboes and the presence of cicatrices in the groin are to be regarded as evi- dence of some local irritation in the genital organs, rather than a proof of constitutional syphilis ; this may, however, coexist with the other. The typical form of glandular en- largement in the groin due to constitutional syphilis, consists rather in the presence of a group of moderately enlarged, painless, and movable or rolling glands, which proceed to suppuration only in exceptional cases. Enlargement of the glands elsewhere may be due to syphi- lis in the exceptional case of a primary sore being contracted in some unusual situation ; a general affection of the whole glandular system is also found at times in constitutional syj^hilis. Enlargement of the glands serves as a valuable indication of an affection of the system in certain forms of cancer or epithelioma ; malignant tumors of the breast affect the axillary glands, malignant growths in the throat affect the cervical glands, and so on. Even deep-seated diseases may reveal themselves by such glandular affections, as in the case of malignant growths at the base of the skull involving the glands in the neck, and cancer of the abdominal organs affect- ing some part of the lymphatic system within our reach. Enlargement of the anterior cervical glands is due in the immense majority of cases to a scrofulous tendency in the patient, and their presence, or the evidences of their former existence, from the scars and cicatrices left, frequently serve to indicate this constitutional taint. They may, however, be due to some of the other causes referred to in this section. These scrofulous glands sometimes remain chronically en- larged, although free from 2^ain. In persons of a weak con- stitution, the lymphatic glands are sometimes enlarged from exj^osure to cold and other comparatively slight causes which would not affect a robust person. Scrofulous glands may occasionally be felt through the abdominal walls in cases of tabes mesenterica, but owing to the swelling and tension of 13 146 GLANDULAR AFFECTIONS. the belly so frequently present in such cases, very often we cannot detect glandular swellings, even of large size. A generalized enlargement of the lymphatic glands is so often associated with Leukcemia, that it is well to examine the blood microscopically when they are thus affected. The rela- tive proportion of white blood corpuscles to the red corpuscles varies greatly even in health, and it is often considerably in- creased in ansemia and also in cancerous affections, but when the proportion, as estimated carefully in various fields of the microscope, amounts to 1 in 20 or 1 in 10, the case may be regarded as one of leukaemia; the proportion is often higher, and the white corpuscles may even equal the red in number. (" See Examination of the Blood," Chapter IX.) In such cases we must see if there is any enlargement of the spleen. Leu- kaemia may exist with enlargement of the lymphatics alone (lymphatic leukaemia), or with enlargement of the spleen alone (splenic leukaemia), or both forms of enlargement may be present. General enlargement of the lymphatic glands may exist without leukaemia, although dependent on some grave constitutional afiection; the name "Hodgkin's disease" is sometimes applied to this special variety, although it is applied by others in a more general sense to cases of various kinds with lymphatic enlargements (lymphadenoma). In such cases there is sometimes a complication from the jDres- ence of a mediastinal or abdominal tumor (lymphoma) of a similar nature ; these may give rise to exudations, and so the case may be mistaken for a pleurisy or peritonitis occurring in a scrofulous subject. Enlargement of the cervical glands is of habitual occurrence in scarlet fever ; it sometimes appears very early in the disease, before the other symj^toms have been developed, but usually comes on about the second or third day of the illness, or even later. It is specially marked in the grave forms with serious affection of the throat ; in young children, the enlarged glands may appear like a collar surrounding the neck, this is always a very serious indication. Glandular affections in connection with ulceration of the throat, appearing late in the course of the fever, are always of special gravity. In scarlatina, these glands often suppurate and lead to extensive sloughing. Glandular enlargements in the neck, especially about the angle of the jaw, are sometimes found in diphtheria and other forms of sore tliroat and tonsillitis, but they seldom attain the size or extent common in scarlet fever. Parotitis. — Inflammation and suppuration of the parotid JOINTS. 147 may be due to scarlet fever, from the general invasion of the glands in this region. Parotitis is a sequela of typhus which is not uncommon. It is but rarely seen in relapsing and other fevers or in erysipelas. Parotitis may also occur as a special affection, due to some specific infection (mumps). It is very liable to spread in schools; the period of incubation is about a fortnight. This disease attacks children chiefly, but not exclusively, and especially between five and fifteen years of age. Sometimes it is unilateral but usually double. There is considerable pain, especially on moving the jaws, and a certain amount of fever and constitutional disturbance is common. This form of paro- titis seldom proceeds to suppuration, but it sometimes sets up a purulent otitis. Occasionally affections of the breast or tes- ticle, by metastasis, have been observed. An affection of the parotid, differing from mumps, associated with marked swelling and even suppuration, may depend on the implication of the lymphatic glands in its vicinity rather than on inflammation of the parotid itself. The salivary glands when much swollen or affected with calculi usually come under the notice of surgeons. Plague, Glanders, etc. — Acute glandular swelling (buboes) in the axilla, groin, and neck are found as a rule in the plague, associated often with carbuncles and other evidence of serious disturbance, but this disease is not now prevalent in Europe. Glandular swellings are likewise found in connection with glanders and farcy, occurring in men infected from horses, asses, and mules ; sometimes pustular eruptions and discharges from the nose likewise appear. The Joints. The joints should be examined in all cases in which they seem painful. When, from the presence of fever or any other cause, we suspect the existence of acute rheumatism, gout, or pyaemia, we must make a careful search in the joints for any swelling or tenderness. In syphilis, also, the history of pain in the joints is often important. The presence of chronic disease of the joints, or the evidence of past mischief in them, may often throw light on the scrofulous, rheumatic, or gouty ten- dencies of a patient ; the evidence of old disease in the joints, or former suppuration, may serve to explain the existence of lardaceous disease of the viscera. Local disease of the joints 148 JOINTS. comes for the most part under the care of the surgeon ; the discrimination of the various lesions from one another, and from hysterical affections, which occasionally assume this form, must be sought in surgical works. On the border-line between medicine and surgery is the form of disease popularly called ''rheumatic gout,'' but more correctly named ''rheumatoid arthritis," or " chronic rheumatic arthritis ;'' this is characterized by more or less pain, but especially by enlargement of the ends of the bones, and deformity or "nodosity of the joints;" the parts involved are often twisted out of their position. The knuckles are perhaps the parts most frequently involved in the early stage, but all the joints of the limbs, and even the articulations of the jaw, may be more or less affected. A certain crackling sensation is often ex- perienced by placing one hand over the joints while moving or manipulating them with the other. Although essentially a chronic disease, the patient may have acute or subacute attacks superadded ; we then find redness, swelling with effusion, and tenderness ; in some cases there may be a considerable resem- blance to gout. Enlargement of the ends of the bones always implies an old-standing affection; osseous deposits may like- wise exist in the adjoining ligamentous tissues, and may even be found lying loose in the joints. The general health is usually deteriorated, and the articular mischief often dates from some debilitating or exhausting illness. Enlargement of the ends of the bones, and other osseous growths and deformities resulting from spontaneous fractures, are met with occasionally in cases of locomotor ataxy ; or the cartilages may become eroded, giving rise to crackling sounds on manipulation, and even to spontaneous dislocation ; the large joints are those chiefly affected in this disease. Chalky deposits in the joints sometimes simulate the deformity of rheumatoid arthritis, and some doubt may remain in certain cases till the deposits are exposed by ulceration. Enlargement of the ends of the bones, with the appearance of " double joints," occurs in children as one of the characteristics of rickets. (See " Bones.") In acute articular rheumatism (rheumatic fever) pain in the joints is usually an early symptom, although there may be high fever for a day or two before this becomes pronounced. When the pains are present in various joints we can seldom mistake the nature of the illness. But when the joints of the spine seem the only parts affected, we may indeed be in doubt, as pain of this kind often arises from serious disease of the bones, or from EHEUMATIC AFFECTIONS. 149 certain affections of the spinal cord, or of its membranes. For this reason any case of rheumatism, with acute symptoms, involving the back chiefly, without any swelling of the joints in the limbs, must always be scrutinized carefully during its progress, as many mistakes arise from applying the name " rheumatism " to such an illness ; pain in the limbs, with great tenderness on handling them, may be present in the spinal affections referred to, and this tends further to simulate rheumatism ; more rarely, cerebral meningitis may be char- acterized by hyperaesthesia in this way, and cerebro-spinal meningitis usually presents this symptom. When the patient is known to have had articular rheumatism, the case is so far simplified ; a rheumatic attack may be confined chiefly to the back, but it usually involves other joints also during some part of its course. Acute rheumatism usually produces very marked swelling, with considerable effusion into the joints, and along with this there is often redness of the skin, and almost always great pain, especially on disturbing their position in any way, so that the patient becomes very helpless, and dreads the least shaking of his bed. The mischief in the joints appears very suddenly ; it is sometimes very fleeting, shifting about from one limb or one set of joints to another, or from one side of the body to the other. Rela|)ses are very common in this disease, and one attack seems to predispose to another. We inquire in cases of this kind for the history of any previous attacks, of any exposure to cold and wet, and also for any hereditary tendency to rheumatism. We must always make a careful search for the evidence of cardiac mischief, this may exist apart from any thoracic symptoms ; there is, however, usually more or less pain in the chest when pericarditis is present. The temperature of the patient is a very important symj)tom in rheumatism ; a strict watch must be kept on it if it seems to be rising very high. With such elevations we may have alarming delirium, coma, or other cerebral symptoms, although the articular pains may be but slight or may even have greatly diminished. Sweating is habitual in acute rheuma- tism, and the urine is usually high-colored and loaded with urates. In children, the joint affection in rheumatism is often so slight and fleeting, that the disease is apt to be overlooked, or attributed to "growing pains." In such cases swelling and pain about the feet are often the most marked features : in older subjects pains in the heels, of an obscure but severe 13* 150 JOINTS. character, seem often to be essentially rheumatic in nature. These slight attacks in children may be complicated with endocarditis or pericarditis, and may lay the foundation of permanent cardiac disease. Chronic forms of rlieumatism are found in elderly people, apart, it may be, from any previous acute attacks. This affec- tion is characterized by pain and stiffness of the joints, and the muscles and tendinous structures are also more or less involved. In other cases we have the complication of rheu- matic arthritis. Quasi-rheumatic affections of the joints occur in scarlatina and relapsing fever. In the former the articular affection occurs usually after the first violence of the fever is over, and often coincides with the period of albuminuria and cutaneous desqua- mation. There is not usually much swelling in the joints, but the pain is sometimes very considerable. (For more serious articular affections in scarlatina, see " Pyaemic affections of the joints," p. 152.) In relapsing fever, pains in the joints occur at the begin- ning of the febrile attack, and often add materially to the general suffering. They may also return with the relapse. The presence of high fever and of articular pains in this dis- ease simulates acute rheumatism- very closely, but the epi- demic character of relapsing fever, and its complete absence for years together in this country, prevent any very frequent errors in this respect. Here, also, the joints are but little swollen as compared with the usual form of rheumatism. Arthritic pains and swelling occur in connection with purpura (see p. 153), and also with the hemorrhagic diathesis (see Chapter IX., "Hemorrhages"). Gonorrhoeal rheumatism (gonorrhoeal synovitis) is compara- tively a rare affection. It must not be supposed to include all the cases of chronic articular pains in patients w'ho have had at some time a gonorrhoeal discharge. Gonorrhojal rheu- matism arises during the period of the urethral discharge. It is rare, but not unknown, in the female sex. It usually attacks the knee-joint, but it may involve various joints in succession, and even the synovial sheaths of the tendons. Its appearance may be marked by a diminution in tlie discliarge. It tends to recur with a subsequent gonoirhocal infection, or even with other forms of urethral irritation, or it may linger as a more clironic affection associated with a gleety discharge, or even after this has disappeared ; recurring disease is apt to lead to serious destruction, or to stiffness of tlie joint ; although the GOUT. 151 health suffers seriously, the patients seldom die of the disease. Occasionally this gonorrhoeal rheumatism is associated with ophthalmia at its commencement, and with iritis in its later stages. As a rare occurrence we may have true pysemic syno- vitis from gonorrhoea, with its usual gravity. Gout manifests itself by pain and swelling in the joints, asso- ciated with more or less general disturbance ; and it appears both in acute and chronic forms. Gout has a special tendency to affect the ball of the great toe, especially in the first attack, but almost any joint may be involved ; previous injury renders a joint particularly liable to the gouty inflammation, and this may determine the site of the seizure. The joint becomes ex- ceedingly painful in an acute attack, especially if it be the first ; there are usually great swelling, redness or lividity, and tension ; the veins are usually much swollen, and after the tension subsides, oedema of the part remains, and the skin desquamates. The paroxysms of pain have a marked tendency to nocturnal exacerbations. The fever is usually much less than in rheumatism, and its intensity seems more distinctly related to the local inflammation. General disturbance, and especially gastric disorder, characterized by acidity, may be regarded as usual, and cramps in the muscles are not uncom- mon. Alarming symptoms referable to the stomach, heart, or nervous system sometimes occur in connection with gouty attacks, or with a recession of the articular affection. The fleeting and erratic forms of attack common in rheumatism are not found in gout. The personal and family history are very important in the diagnosis of gout in doubtful cases. Gout is rare in Scot- land, except among the upper classes, although not uncom- mon amongst workingmen and hospital patients in London. It is more common in men than in women, and seldom appears till the patient is about forty years of age. The influence of heredity is very strongly marked, and this may determine an attack in those who are very careful in their living. The habits of the patient as to excess in eating and drinking are, however, very important ; the use of malt liquors and wines predisposes to gout much more strongly than even a free use of spirits. Excess in the use of animal food is likewise potent in producing gout. The connection of lead-poisoning with gout seems also to be so frequent, in London at least, as to assist in the diagnosis. The occurrence of renal aflfections in gout is likewise common, and should be inquired into, and the state of the heart and arteries should likewise be investigated. 152 JOINTS. The test of the gouty condition by finding crystals of uric acid in the serum of the blood is important. Dr. Garrod recommends two drachms of the serum of the blood to be placed in a flat glass dish and set aside to evaporate slowly ; it is first acidulated slightly with acetic acid, and a fine linen fibre is introduced into it ; when the fluid has been reduced to the consistency of a jelly, this fibre is found crusted over with crystals of uric acid if the blood be derived from gouty patients, but there are no crystals from the blood of those free from this taint. Chronic forms of gout become developed from repetitions of the acute affection. In gout the tendency is for the recur- rences to be more and more frequent, with less distinct causes for each attack. The joints are also apt to become permanently changed, particularly from the deposit of chalky masses in their structures. These are called " chalk-stones " (or toj^hi — i. e., concretions) ; they consist chiefly of urate of soda along with animal matter ; their composition may be determined as in the case of urinary calculi. Sometimes these concretions give rise to small abscesses, and in this way become exposed. They are found in various joints. Before they become visible the diagnosis of these hard masses in the joints may be doubt- ful, as they may simulate some enlargement of the ends of the bones. Assistance is afforded at times by finding similar small concretions in the ear, especially in the helix, varying in appearance from the minutest possible vesicle beneath the skin to a bead-like nodule resembling a pearl. The constitutional symptoms in chronic gout vary consid- erably ; dyspeptic disorders form the leading feature in such cases. Pyoimie affections of the joints occur in many cases of pyaemia as they arise in surgical practice. With these we have no concern here. Affections of this kind occur after childbirth, sometimes at a considerable time after delivery, associated it may be with evidence of suppuration elsewhere (pelvie abscess, phlebitis, pyceynia, etc.). Essentially the same kind of articular mischief occurs also sometimes in scarlatina. This puerperal and scarlatinal form of pysemic arthritis is limited to one joint in some cases, but in others various joints are affected. Such illnesses, although always serious, are not necessarily fatal. Pysjemic disease of the joints sometimes occurs also after cer- tain forms of pneumonia, with typhoid symptoms, and after enteric and some other fevers. When suppuration is known to be going on in a case, we must always regard articular BONES. 153 pains with great suspicion ; gonorrhoea has been known to give rise to true pyaemia, and gonorrhoea! rheumatism is regarded by some as a mild form of this disease. Pysemia, with affection of the joints, sometimes occurs in an idiopathic form, as it may be called — that is, without any obvious cause. In such cases the symptoms may resemble those of enteric fever, although shive rings are usually present in a more loronounced form. In obscure cases it is well to examine the various joints as to swelling, redness, and tender- ness to pressure. Pysemic joints are usually painful, but sometimes the pain is not well marked ; tenderness is very generally present even in such cases. The pysemic affection has but little of the fleeting or shifting character of acute rheumatism, but we may see, even in fatal cases, the implications of certain joints followed by their recovery, and it may be the supervention of mischief in others. Actual pointing of a pysemic joint may take place. Articular ijains with subcutaneous hemorrhages occur both in purpura and scurvy. There is a disease, " peliosis or pur|)ura rheumatica," in which fresh developments of articular pains and of hemorrhagic spots appear together, and there may be hemorrhages elsewhere as well; it is regarded by some as a mere coincidence of purpura with a rheumatic attack. In scurvy the articular pains and stiffness of joints, due to the fibrinous effusions found in this disease, are often so perma- nent as to lead to the idea of rheumatic instead of scorbutic disease. Affections of the joints are also found in the hemor- rhagic diathesis. (See Chapter IX., " Hemorrhages.") Syphilitic affections of the joints occur in a slight form in what is termed the secondary stage. But the more severe and persistent pains occur later, among the tertiary symptoms, when nodes, etc., become developed. These pains usually affect several joints, and especially involve the larger ones ; they have a very marked tendency to nocturnal exacerbations, and the ^^ains are often evidently present in the bones as well as the joints. Other evidences of syphilis usually coexist with these pains when they are severe. This manifestation of syphilis has some value in judging of the history of a doubtful case. Bones. Affections of the bones come so much more under the notice of surgeons that we must refer to surgical treatises for in- 154 BONES. formation on this subject ; only a few points of special impor- tance to the physician claim attention here. Co7igenital malforraations of the skull and spinal column (encephalocele and spina bifida), with protrusion of the brain and spinal cord, or of the membranes, are often impor- tant as furnishing the exj^lanation of convulsive or paralytic symptoms. Affections of the skull are met with in rickets, hydroceph- alus, and syphilis whether this is congenital or acquired. The enlarged head of rickets may be mistaken for the slighter forms of hydrocephalus ; the head, however, has more of a square shape in rickets, more of a globular form in hydro- cephalus ; the top of the head is usually flatter in rickets ; and although the sutures and fontanelles are often unduly wide in both, we can sometimes trace the thickened edges of the rickety bones forming distinct ridges where the sutures are. In both diseases the small face often contrasts with the en- larged head, but this is usually more striking in hydroceph- alus ; in this disease also the eyes appear strikingly prominent from the balls being directed downward, and from the expos- ure of a large portion of the upper part of the white sclerotic. Great thinning of the bones of the skull (craniotabes) is found as an early symptom in rickets and also in congenital syphilis. By searching with the finger over the occipital and adjoining portion of the parietal bone, in particular, little patches about the size of the point of the finger may be de- tected so soft and thin as to feel like membrane. On the other hand, thickenings of the bone may be encountered in congenital syphilis, when it involves the skull, so that four bony eminences may surround the fontanelle. (Parrot.) Syphilitic aflfections of the skull in the adult, with nodes or with suppuration and necrosis (corona veneris), are well known to surgeons ; they may likewise point the physician to mischief within the cranium, giving rise to nervous lesions. Old depressions or painful cicatrices have to be searched for and considered in certain cases of epilepsy. The examination of the head by auscultation and percus- sion will be mentioned in the study of nervous symptoms in Chapter VI. Periostitis, Necrosis, Ostitis, Caries. — These arc usually re- garded as purely surgical, but they may have many close relationships with internal disease. Syphilitic periostitis and nodes aflfecting the skull have been already alluded to, but it is often important to search on the tibia for evidence of old ENLARGEMENT OP THE BONES. 155 lesions of this class in suspected syphilis. Present or past periostitis, necrosis, and caries may throw light on the consti- tutional tendency of the patient, or of his relatives, and may point to certain pulmonary or cerebral disorders being in all probability tubercular ; or such affections may give the clew to the diagnosis of lardaceous disease of the kidney, liver, spleen, and intestines. All such affections of the bones are usually so obvious, and are almost always attended with so much pain, that they can scarcely be overlooked. Occasion- ally, however, in young subjects, acute periostitis and " necro- sial fever " may simulate a general disorder, and may be readily mistaken for typhoid or some other fever, at least for a time ; the diagnosis may become further complicated by its giving rise to pysemic pericarditis, pleurisy, etc. In connec- tion with periostitis it may here be stated that necrosis some- times occurs as a sequela of enteric fever. Deep-seated pains in the bones, with marked nocturnal exacerbations, may afford indications of syphilitic disease. Enlargement of the epiphyseal extremities of the hones is a notable symptom in rickets ; it occurs chiefly in the wrists and ankles, but it shows itself also in "beading" at the junction of the ribs with the costal cartilages ("rachitic rosary"). These rickety enlargements may sometimes be confused with the swellings due to congenital syphilis found at the epiphyses also ; but while both are affections of infancy, the syphilitic lesion is common under six months, while rickety changes in the bones are seldom pronounced till some months later. In syphilitic affections involving the arms the child may appear to be paralyzed from this cause, and this "pseudo-paralysis" may assist the differential diagnosis. These deposits may sup- purate but they seldom open into the joints. Although the ends of the bones are the common sites of the syphilitic lesion, they sometimes lead to local enlargements in the shafts, and when they involve the phalanges we have the variety termed " dactylitis syphilitica." In the form of disease termed " acute rickets " the enlarge- ments are very rapidly developed, and present more pain than the mere tenderness of ordinary rickets. This form of disease has been shown by Dr. Barlow to depend on acute hemor- rhagic lesions due to scurvy or to some tendency allied thereto. It may coexist with true rickets, but it may occur without any manifestation of this disease. Enlargement of the ends of the bones due to rheumatism has been discussed under " Joints." (See p. 147.) 156 BONES. Distortion of the long bones is found to a notable extent in rickets. In the ribs it leads to the occurrence of various forms of "pigeon breast;" this deformity will be referred to and its meaning discussed in Chapter XVI. In the lower limbs it is seldom present to any striking extent, unless the child has begun to walk, or at least to stand, and so the Avorst cases of rickets, early developed, do not show much deformity of the legs. The distortion resulting is best ujiderstood if we imagine all the natural curves and twists of the long bones intensified to a greater or less degree ; sometimes this is enor- mous ; but the bones may be twisted, from accidental causes, in quite difierent directions from the normal curves. The bones of the upper extremity are also often distinctly curved, particularly in those patients who have been too badly affected with rickets to allow of their standing or attempting to walk. In such cases the little patient sitting in bed, and moving him- self from side to side with his arms, produces a curving of the bones there from the weight of his body falling upon them instead of on the legs. The clavicles are often so sharply bent as to suggest the idea of a fracture. Softening of the bones in adults (mollities ossium) is chiefly of importance from its distorting the spine and pelvis of women during the childbearing period. It is associated with obscure pains, and from the distortion the woman's stature may be diminished to the extent of two or three inches. Although much commoner in women it occasionally affects men, and the ribs and sternum may be implicated as well as the bones of the limbs, pelvis, and spine. Distortions of the spine must be studied as to whether they are permanent, or whether they disappear on taking the weight off the vertebral column. We also ascertain whether they are lateral (skoliosis) ; angular, with projection backward of the spinous processes (kyphosis) ; or if there is a general bulging backward of the dorsal and lumbar regions, with slight pro- jection forward of the cervical portion, such as arises from general weakness or softness of the bones, as in rickets ; or if there is a "saddleback" appearance, with projection forward of the lumbar and lower dorsal region, and backward of the upper dorsal and cervical portion of the spine. The lateral distortion is found chiefly in girls of poor physique ; but such deformities, even when extreme, do not give rise to paralysis. Lateral curvatures also result from pleurisy with retraction of one side of the chest, especially when this occurs in childhood ; and any inequality in the lower limbs, or arrest in growth, such BIBLIOGRAPHY. 157 as occurs in infantile paralysis, tcDcIs to produce this deformity. Angular curvature is found in caries of the vertebrae (Pott's disease), and is often associated with abscess in various parts, with severe neuralgic pains, and with paralysis. The deformity named lordosis or "saddleback," occurs at times as an inde- pendent affection, but is chiefly interesting to physicians as one of the leading peculiarities of pseudo-hypertrophic muscular paralysis.

EXAMINATION OF THE ORGANS OF SPECIAL SENSE: TESTING OF CRANIAL NERVES. An examination of the organs of special sense is often called for in the study of nervous symptoms. The investigation here, as elsewhere, resolves itself into an objective and subjective division. Under the " objective" we include those indications of disease obvious to the observer, or at least capable of dem- onstration by some reliable test. Under the "subjective" we have various symptoms for the existence of which we have to rely more completely on the mere statements of the patient, although these also may be susceptible of some scrutiny. As the two sets of symptoms often pass into each other, no separ- ation of them will be made in this chapter. The Eye. The examination of the eye affords indications of the greatest variety and importance. No allusion will be made here to diseases of the eye itself, unless in so far as these bear on general diagnosis, or unless they might lead to confusion or error. The yellotu discoloration of the conjunctiva is discussed else- where in connection with jaundice. For the various points bearing on the diagnosis of jaundice, and on the color of the sclerotic, see " Jaundice," Chapter XII. Opacities of the cornea, traces of old iritis, and the like, are sometimes useful as indicating, along with notched teeth and other signs, certain constitutional affections, especially syphilis and scrofula. Acute iritis may supervene in syphilitic, rheu- matic, or gouty cases while under observation. The cornea may become opaque or may ulcerate from lesions of the fifth nerve, or it may suffer in this way from exposure due to paralysis of the seventh nerve. The arciis senilis consists of an opaque ring or segment of a ring, in the cornea at its junction Avith the sclerotic. It usually exists in both eyes, when present at all, but it may be present 160 OEGANS OF SPECIAL SENSE. to an unequal extent. It occurs habitually in persons over 60. When present in younger subjects (35 to 50) it is to be regarded as a sign of early degeneration of the tissues ; it is very often associated with atheroma, gout, renal disease, and cardio-vas- cular changes. The complete ring round the cornea is re- garded by some as less suggestive of degenerative processes than the segment to which the word "arcus" more properly refers. It would seem that strain on the eyes such as may arise from much microscopic work favors the early develop- ment of this change in the cornea. Suffusion of the eyes, with injection of the conjunctiva and lachrymation, is often due to local inflammation ; but we also find it at the beginning of certain fevers, especially measles and typhus. It may likewise constitute one of the early signs of meningeal and cerebral diseases. It is often associated with photophobia. Photophobia, or intolerance of light, is common to many diseases of the eye (phlyctenular ophthalmia, keratitis, iritis, and retinitis). It is also found in certain stages of meningitis, cerebral tumors, typhus, measles, etc. It is common in many varieties of headaches and especially in migraine. In nervous subjects it may exist apart from any serious changes in the eyeball, there being thus a hyper&esthesia of the retina. Protrusion of the whole eyehall (exophthalmos) may indicate abscess of the orbit, thrombosis of the cavernous sinus, or tumor somewhere behind the eyeball ; in such cases it is usually unilateral. When it affects both eyes, and when asso- ciated with enlargement of the thyroid, and rapidity of the heart's action, it constitutes an important element in the diag- nosis of exophthalmic goitre. Occasionally the protrusion is- much greater on one side than the other in this disease, and in rare cases it may be unilateral ; when the patient looks down, the upper part of the sclerotic is unduly visible, from the upper eyelid not following the eyeball in its downward look, and this feature aflTords us some guidance even when the exophthalmos is slight, or, it may be, still absent on one side. Complete paralysis of the ocular muscles, or of the third nerve, may lead to a slight protrusion of the eyeball, from the removal of the backward tension of these muscles. Consider- able variation exists normally in the prominence of the eye- balls. Inability to clo^e the eyelids properly (lagophthalmos) is very common, but not invariable, in peripheral paralysis of the facial nerve. (See "seventh nerve," p. 203.) It is uncommon, SQUINTING OR STRABISMUS. 161 although not unknown, in the paralysis of the face of ordinary hemiplegia from cerebral causes. Exposure of the eyeball may lead to irritation of the conjunctiva or cornea. From implica- tion of Horner's muscle the tears often run down the cheek. Ptosis, or droop of the iipj^er eyelid, is a sign of paralysis of one of the branches of the third nerve. Sometimes, however, it is not paralytic, being obviously due to some mechanical impediment to the action of the muscles or eyelids themselves. When paralytic, ptosis may exist alone, or be combined with other evidences of a lesion of the third nerve, or of intracra- nial disease. The movements of the eyelids, according to Dr. Gowers, are associated with, and to some extent due to, the movements of the eyeballs. In its downward movement, the eyeball com- municates a mechanical depression to the lower lid. In the case of the upper lid, the levator palpebrse is made to act or relax, by an " associated movement," with the concurrent action or relaxation of the superior rectus animated by the same nerve. Hence, in paralysis of the inferior rectus we may have an apparent paralysis of the eyelids when the patient tries to look down, from the want of the relaxation of the levator palpebrse usually associated with the contraction of the inferior rectus. We may also have in a case of ptosis, due to cere- bral disease, an upward movement of the upper lid when the patient exerts his superior rectus in looking up, although there may be no voluntary power over the levator palpebrse apart from this associated movement. Squinting, or Strabismus — Paralysis of the Ocular Muscles — Diplopia. — In examining for strabismus we get the patient to direct his vision with both eyes open, to a point placed exactly opposite him in the middle line. The ob- server's finger held in such a position suits quite well. This is tried at various distances, both near and remote, and we notice whether the centre of the cornea coincides with the centre of the palpebral fissure. If a deviation occurs (primary deviation), we should notice w^hether this comes into more prominence when near or when distant objects are looked at ; we also observe whether the eyeball is turned inward (internal or convergent strabismus), or whether it is turned outward (external or divergent strabismus) ; we can usually say at once which of the two eyes is the one whose axis of vision is directed to the object, and which is the one which deviates. Sometimes, however, the patient can "fix"' the object with either eye indifferently, and so either the one or the other may 14* 162 OKGANS OF SPECIAL SENSE. deviate (" alternate squint "). When the same eye is always used to " fix " the object there is usually a distinct difference in the acuteness of the vision on the two sides — the better eye being, of course, selected by the patient for this purpose. If now we get the patient to "fix" the object with the less per- fect eye, by interposing the hand before the sound one, or by placing a piece of dimmed glass in front of it, we may then find that the sound eye (which was quite straight in the former experiment) deviates inward or outward, just as the other did. In many cases this "secondary deviation," as it is called, can be ascertained, by a scale placed below the eyelid, to be exactly equal to the primary deviation : this is the common case when the squint depends on hypermetropia and myopia apart from any paralysis of the ocular muscles (" concomitant squint ") ; in paralytic squint, on the other hand, the second- ary deviation is often more extreme than the primary, and this sometimes constitutes an important indication of ocular paralysis. A deviation, however, which originated in a paral- ysis in a hypermetropic or myopic patient, may be perpetuated as a concomitant squint after the paralysis has passed away ; and in rare cases, from the persistence of a non-paralytic squint, and the stretching of the fibres of the muscle, w^e may find a want of proper movement from simple muscular weak- ness aport from any paralysis of nervous origin. In cases o^ " concoynitant squinV there is no impairment of the movement of the eyeballs ; this can be shown by testing the eyes sej)arately — only one being open at a time, and the object looked at being carried up and down, and to the extreme right and left ; the free mobility of each eye in all directions may then be ascertained. Strabismus having these peculiari- ties is due to a want of proper adjustment in the action of the muscles, or to a certain shortening of one or other of them ; such a squint depends, in the great majority of cases, on errors in the refraction of the eye, convergent squint being associated with hypermetropia, and divergent squint with myopia; in a few cases, however, this relationship may be reversed. These errors in refraction are in many cases hereditary, so that a tendency to squinting is often inherited. In such cases of strabismus, binocular or stereoscopic vision is usually sacri- ficed at an early period in the case, and so the patient is not troubled with dii)lopia. Specks on the cornea, and other defects in the vision, often seem to determine tlie occurrence of squinting and the suppression of the vision in the weaker eye. Patients with hypermetropia and myopia may also have DIPLOPIA BINOCULARIS. 163 squinting very readily induced by various acute illnesses of a general nature ; this squint may be temporary or permanent. It may thus simulate a cerebral disturbance under certain circumstances. In paralytic squint the movement of the eyeball is impaired in certain directions, so that it cannot be moved outward or inward beyond the middle line, as the case may be ; the sound muscle may also overbalance the paralyzed one, so that, for example, in paralysis of the external rectus we have often an internal squint, and in paralysis of the internal rectus an external squint. Before concluding that there is ocular paralysis, we must see that no merely mechanical impediment exists to hinder the movements. In paralytic squint the " sec- ondary deviation," already described, is often greater than the primary, and when the vision is directed toward the paralyzed muscle, or, more strictly, in the direction of its action, this is often very extreme. Thus, if a person with paralysis of the right external rectus be tested as to his affected eye (the vision of the other being obstructed with a dimmed glass), and if he be directed to look at an object on his extreme right, the ner- vous energy is directed to the right external rectus and to the left internal rectus, so as to execute this conjoint movement ; as the paralyzed muscle does not respond properly, a still fur- ther force is directed to these muscles, and thus the internal rectus of the sound eye is led to contract excessively, quite beyond anything that is required, and so produces a marked " secondary deviation ;" its pupil may, indeed, be buried within the palpebral fissure. Diplopia hinocularis is common in paralytic squint ; indeed, diplopia may constitute the only evidence of a slight paralysis of an ocular muscle; for when this "paresis" (as a slight loss of power is called) is not too great, there may be no discern- ible diminution of the movements of the eyeball. Diplopia is usually complained of by patients when it is present to any marked extent, but the " false image " is often extremely faint, and the separation of the two images is sometimes slight, or only developed in certain directions of the vision. Moreover, it is important to determine the relation of the two images to the respective eyes, and so a careful test is often demanded. A candle in a dark room, placed at different heights, and in different positions to the right or left of the patient, may be used. It is well also to have a piece of red glass to place before one of the eyes, so as to allow of the identification of each image by its color. If the vision of one eye is less per- 164 ORGANS OF SPECIAL SENSE. feet than that of the other, we place the colored glass before the sound eye, so as to render the defective image relatively plainer. Indeed, this method may reveal a diplopia which would otherwise escape the patient's attention. The faulty image is usually recognized, apart from this contrivance, by a certain dimness, or obscurity as compared with the other ; the false image may be placed at the side of the other ; or above or below it ; or there may be an obliquity in its position ; at times, also, one of the images has a different projection in space, appearing nearer to the patient than the other ; these differences depend on the affection being due to paralysis of the superior, inferior, external, or internal recti muscles, or of the superior or inferior oblique, or to various combinations of these lesions. With regard to the lateral displacement of the false image, we must ascertain whether the diplopia is " crossed " or " di- rect." If, from the shadowy character of the " false image," or by alternate closing of the eyes, or better still by the assist- ance of the colored glass the image to the right be found to be that which is seen with the right eye, then Ave call the diplopia " direct " or " homonymous." If with the same test we find that the image identified with the right eye is seen to the left, then we call it " crossed." " Crossed " diplopia occurs in paralytic divergent squint, or when there is a tendency to di- vergence of the axes of the two eyes from paresis of the in- ternal recti ; " direct " diplopia occurs when there is conver- gence or a tendency thereto. The images may also be superimposed, the one above the other, and this is usually associated with a certain obliquity in the position of the image seen by the paralyzed eye ; this may be slightly " crossed " or not in different cases. (See p. 166.) In order to facilitate the investigation of these varieties of paralysis the following details are submitted in a tabular form : FUNCTIONS OF OCULAR MUSCLES. Rectus superior elevates the axis of vision and slightly inverts the Uf)per part of the vertical meridian of the eye. Obliquus inferior^ elevates the axis of vision and slightly- everts the upper part of the vertical meridian of the eye. 1 The rectus superior aud the obliquus inferior are tlius required jointly for a pure elevation. OCULAE PARALYSIS — DIPLOPIA. 165 Eectus inferior depresses the axis of vision and slightly inverts the lower part of the vertical meridian of the eye. Obliquus superior^ depresses the axis of vision and slightly everts the lower part of the vertical meridian of the eye. Kectus internus inverts the axis of vision. Rectus externus everts the axis of vision. OBLIQUE MOVEMENTS. Elevation with adduction. Eectus superior and internus with ob- liquus inferior. Depression with adduction. Rectus inferior and internus with ob- liquus superior. Elevation with abduction. Rectus superior and externus with ob- liquus inferior. Depression with abduction. Rectus inferior and externus with ob- liquus superior. Hence we find that the position of the eye or of the pupil varies according to the special muscle paralyzed, when the paralysis is of such a degree as to give rise to deviation. Moreover, as this deviation depends on the activity of the sound muscles quite as much as on the weakness of the para- lyzed one, the results are not always uniform, as we may have to deal with a complex paralysis. In the following tabular statement only one muscle is presumed to be afiected, the rest being sound. RESULTS OF PARALYSIS OF SPECIAL OCULAR MUSCLES WHEN THE OTHERS ARE SOUND. Paralysis of rectus superior: inability to raise eyeball properly above horizontal level ; pupil may diverge somewhat downward, and a little outward (from action of the rectus inferior and the obliqui). Paralysis of rectus inferior: inability to lower eyeball properly below horizontal level; pupil may diverge somewhat upward, and a little outward (from action of the rectus superior and the ob- liqui). Paralysis of rectus externus: inability to turn eyeball properly out- ward ; pupil diverges inward (from action of rectus internus). Paralysis of rectus internus : inability to turn eyeball properly in- ward; pupil diverges outward (from action of rectus externus). Paralysis of obliquus superior : but little alteration in movements of eyeball ; slight deviation of cornea upward and inward, or simply upward. Paralysis of obliquus inferior; but little alteration in movements of the eyeball; slight deviation of the cornea downward and in- ward. (Paralysis of the sphincter of the iris, giving rise to a 1 The rectus inferior and the obliquiis superior are thus required jointly for a pure depression. 166 OKGANS OF SPECIAL SENSE. moderate dilatation of the pupil, and to paralysis of the accommo- dation, often accompanies this form of paralysis ; this depends on the branch to the lenticular ganglion being given off from that branch of the third nerve which goes to the inferior oblique muscle. Occasionally, however, the lenticular branch arises from the sixth nerve.) DIPLOPIA IN OCULAR PARALYSIS. Diplopia is specially, or perhaps only, develoj^ed when the axis of vision is turned in the direction in which the action of the paralyzed muscle should be called into play: thus, upward when the elevators are paralyzed, downward when the depres- sors are involved, and outward or inward in the case of the exterual and internal recti. Certain actions, as climbing or descending a ladder, may thus bring a diplopia into trouble- some prominence ; on the other hand, a certain position of the head is often assumed by the patient so as to prevent the ten- dency to diplopia. In testing, we require therefore to use various positions for the object. As already explained (p. 164), the diplopia is " crossed " when from paralysis or weakness there is divergence of the visual axes or even a tendency thereto, and for similar reasons w^e have " direct " diplopia when the tendency is toward con- vergence. The action of the superior and inferior recti as tending to turn the axis of vision somewhat inward, when their correctors are paralyzed, and of the two obliqui as tend- ing to evert it when the counter-balancing muscles are para- lyzed, must also be remembered. (See p. 165.) HOMONYMOUS AND CROSSED DIPLOPIA. External rectus paralyzed: diplopia is not "crossed;" images on same level ; displacement increased by moving the object out- ward. Internal rectiis paralyzed: diplopia is "crossed;" images on same level ; displacement increased by moving the object toward the sound side. Superior rectus paralyzed : diplopia vertical and "crossed;" image seen by faulty eye above the other, and somewhat obliquely, chiefly when vision is directed upward. Inferior rectus f»aralyzed : diplopia vertical and " crossed ; " image seen by faulty eye below the other, and somewhat obliquely, chiefly when vision is directed downward. Superior oblique paralyzed: diplopia vertical and not "crossed;" image seen by faulty eye below the other, and somewhat ob- liquely, chiefly when vision is directed downward. Inferior oblique paralyzed : diplopia vertical and not " crossed ; " image seen by faulty eye above the other, and somewhat ob- liquely, chiefly when vision is directed upward. SIGKIFICANCE OF SQUIKTIKG. 167 Listinctive efforts to combat the diplopia are often observed in patients, as the presence of the " false image " gives rise to a feeling of distress, and is apt to lead to error and confusion in estimating the position of objects. The most natural and in- telligible counteracting movement is the closing of the affected eye, and so at first sight it may seem that the patient has ptosis : the drooping of the uj^per lid, however, is readily seen to be due not to paralysis of the levator, but to a voluntary action or even to a spasmodic contraction of the sphincter. Again, the diplopia is developed, in a case of paralysis of the abducens, because the patient cannot direct the eyeball outward, and the diplopia becomes marked in proportion as the object looked at calls for tbis action. But although the patient cannot turn the eye outward he can rotate the head in this direction, and by maintaining the head in such a position as to supplement the action of the weak muscle he can often minimize the troublesome diplopia. These habitual devia- tions of the head become in this way suggestive of special forms of ocular paralysis. POSITIONS OF THE HEAD IN OCULAR PARALYSIS. In paralysis of the sixth nerve the face is turned toward the paralyzed side. In paralysis of the fourth nerve the face is directed downward and toward the shoulder of the paralyzed side. In paralysis of the third nerve the face is turned habitually toward the shoulder of the sound side to combat the weakness of the internal rectus. Special positions of the head upward or downward may be required in ascending or descending, owing to the elevators and depressors being likewise paralyzed, Sometimes, from the presence of ptosis also, no effort is required to avoid the diplopia, as the vision exists then only on the sound side. The Clinical Significance of Squint, Ocular Paralysis, and Diplopia. — When a squint is not of paralytic origin it has not much significance to the physician, but on this very account it is important that he should be able to distinguish such cases. Occasionally a squint originates in a paralysis, although this may have passed quite away ; in such a case it has some sig- nificance in the history. But it must also be remembered that in subjects predisposed to strabismus by optical defects, a con- comitant squint may originate in connection wdth any acute illness quite apart from paralysis. When a squint is due to paralysis of the third, fourth, or sixth nerves (see pp. 202, 203) it has great significance. As a 168 OEGANS OF SPECIAL SENSE. rule, these nerves are affected by lesions at the base of the brain, or the base of the skull, so that some interference with the nerve itself in its course is indicated, rather than a lesion at its deep origin ; the lesion is thus on the same side as the paralyzed muscle. Hence these nerves are specially involved in cases of cerebral tumor and basal meningitis ; they are all very fre- quently paralyzed from syphilitic disease within the skull. When one of these nerves is involved, the other cranial nerves must also be examined, as combinations of paralysis of the sixth nerve with patclies of anaesthesia in the region of the fifth, for example, are even more suggestive of syphilitic lesions. Paralysis of the fourth nerve is usually due to syphilis. Paral- ysis ot' these three nerves, however, and especially of the third, may often be classified with the so-called "rheumatic" paral- ysis — that is, they seem to be induced by cold. Paralysis of the third nerve, Avlien complete, includes droop of the upper eyelid (j^tosis), paralysis of all the muscles of the eyeball except the external rectus and the superior oblique, dilatation of the pupil, and some defect in the power of accom- modation. This paralysis of most of the muscles leads to great deficiency in the mobility of the eye, as already explained, and the I3upil is directed outward and somewhat downward. The paralysis of the sphincter of the iris should be specially studied in connection with the signs of paralysis of the inferior oblique muscle (occasionally, however, the supply to the iris comes from the sixth nerve). The dilatation of the pupil in paralysis of the third nerve is only moderate in degree ; it can be rendered much more extreme by the use of atropine. Ex- treme dilatation of the pupil, therefore, may suggest some irritation of the sympathetic, when there is no question of the use of atropine or other mydriatics. The various branches of the third nerve may be paralyzed separately, so that we may have ptosis alone, or external deviation alone, or dilatation of the pupil, or paralysis of the accommodation, or various com- ])inations up to the most complete paralysis of the nerve. Diplopia (double vision with both eyes open) may be asso- ciated .with a paralytic s
