IN selecting the following essays for republication, I have avoided all of a merely controversial character. The first one in the volume may, indeed, be considered somewhat an exception to this rule, but it treats rather of the principles involved, in what in Scotland would be called, the " great ganging plea," between the old and new schools of medicine, than attempts a full argument of the questions at issue. The papers were all written for the 'British Journal of Homoeopathy,' with which I was editorially connected for the first fifteen years of its existence, and which continues its career under the management of my late esteemed colleagues Drs. Drysdale and Dudgeon, whose labours for the advancement of the Art of Medicine will only be fully appreciated by its future historian. CONTENTS. CHAPTER I. PAGE Young Physic... 1 CHAPTER II.

YOUNG PHYSIC. THERE is a point in the development of a complex science, such as medicine, at which it seems to be overburdened by the multitude of its facts and the insufficiency of its generalizations. When it has reached this stage, and come to a dead lock, it gets no aid from those who have the reputation of being its most successful cultivators. For the very endowments which gave them renown at the time when the science required merely the accumulation of materials, or the critical selection of facts and their lucid arrangement, disqualifies them from the higher task of grasping the subject as a whole, and viewing it by the light of general philosophy, discovering the true centre from which it must be re-organized. This great achievement requires more than.the highest powers of analytical acumen, it requires 1 2 YOUNG PHYSIC. the intuition of synthetic genius. And when the voice of the great discoverer, who is destined to renovate his department of knowledge, makes known the central truth, there is none on whose ear it falls more repulsively than on that of the high-priest of the special science itself. Great discoveries belong to philosophy rather than to science; and no class of minds is less prepared to receive them than are those who have devoted themselves to the study of scientific details alone. 0 There is nothing more strange or more lamentable than the total absence of philosophical discernment displayed by those who are now the appointed guardians of medicine. While deploring its present uncertain and unscientific character, they do not seem at all aware of the real cause of its poverty, and propose remedies which would be as useless if got as they are impossible to obtain. Their inability to perceive what medicine stands in need of, arises from the same cause as their rejection of Homoeopathy. If there be any thing more striking in Dr. (now Sir John) Forbes' memorable article' than this, that throughout the whole of it he speaks of theory in medicine as if it were quite an unimportant thing, and as if the whole end of the labours of the medical philosopher were attained if he made himself 1 "Homceopathy, Allopathy, and Young Physic," first published in the ' Brit. and For. Med. Review,' of which Dr. Forbes was editor, it has since "grown into a book, now in its second edition, entitled, ' Nature and Art in Disease.' The article well deserves the epithet "memorable," for it has produced a greater impression upon the mind of the medical profession than anything of the kind during the present generation. By many the writer was looked upon as having betrayed the secrets of the confessional, and was denounced with such clamour as to make him resign his editorial post; by others he was applauded; by all his influence was felt. YOUNG PHYSIC. 3 sure of a sufficient number of facts, it is the constant recurrence of the expression "philosophic practitioner," -whose philosophy seems to consist in doubting much and in doing nothing. Unsparingly as he condemns Homceopathy as tending to degrade physic by making its practitioners artisans, the position he would appoint to medicine is singularly opposed to the usual requirements of an art and a science. Science is certain knowledge, giving the power of prediction; art is the application of that knowledge. But his science consists in knowing that we can know nothing, and the art he recommends us to practice is the dolce far niente! He speaks of Homceopathy as "an ingenious system of medical doctrine, tolerably complete in its organization, tolerably comprehensive in its views," and says that "it is as good and rational a theory as most of our medical theories." With the gTeat leader of philosophic practitioners it seems a very light matter whether a theory be right or wrong. He seems to regard it very much in the light of the shell of an oyster, useful only for containing a nutritious body of facts. It is not surprising that, considering theory to be. so very insignificant a matter, he lightly observes, with an inconsistency which might be culpable in one who took a more serious view of the value of theory, "that we may indeed have sufficient proof to satisfy any reasonable mind that the theory, or doctrines, or principles of Homceopathy are false," although he does not enter into any such proof, but waives it till a more convenient season. He turns away contemptuously from the consideration of the theory, doctrines, or principles, and eagerly asks what the facts are worth. 4 YOUNG PHYSIC. The facts arrest and startle him. He finds that under the guidance of this theory practitioners of medicine restore to health more patients than under the orthodox method, which disdains, as an infringement upon the liberty of the faculty, to acknowledge obedience to any theory whatsoever. This fact of the greater success of Homceopathic treatment, is a hook in the nose of Allopathy, which must in some way or other be extracted. The problem is this:-By the most authentic returns, more cures are effected in certain dangerous diseases under Homoeopathy than under Allopathy; how, then, is the inference to be prevented that, therefore, Homoeopathy is good, and the position to be established that it is radically bad? This is done in the simplest and most ingenious way. Good and bad are relative terms: it is the same thing to say that a man is better than a monkey, as to say that a monkey is worse than a man. If we say Homoeopathy is better than Allopathy, we suppose some good in the former-more good at least than in Allopathy. But we have only to say Allopathy is worse that Homoeopathy to get rid of the dilemma. And this is the position our great antagonist assumes! But it is urged, if Homceopathy be bad, and Allopathy still worse, how do you retain your allegiance to Allopathy? To this he answers: it is bad in esse, but good in posse; it contains the.germs of its entire renovation, and it only requires proper attention to foster the latent rudiments of good into vigorous growth. How comes it, a sceptic might inquire, that you, who have so long held a chief place in the cabinet of Medicine,-you, her appointed, acknowledged, respected minister, should, till now, never have whispered your be YOUNG PHYSIC. 5 lief that the system you have been directing requires a thorough reformation? How is it that this momentous truth has been forced from you by the doings of so insignificant a body as the Homoeopathists? Surely, in the.,history of our art, among the triumphs of Homceopathy will be recorded,-" It forced Dr. Sir John Forbes to give his candid opinion of the state of medicine. It forced him to make confessions during his life, which otherwise he might have reserved for his testament." But let us follow out the process of Young Physic, and see exactly what it is, and to what it leads:-Allopathy and Homoeopathy are both bad. In their hospitals many patients die, although more recover. The average mortality in both is much alike; the kind of diseases which kill them is much alike. It is plain that, as there is no great difference in the amount of recoveries under the two systems, they must both derive their efficacy from the same cause. Now, as the methods of treatment are wholly opposite, the benefit must accrue from something beyond or outside of the treatment altogether. The only thing beyond that, common to both, is the natural power of recovery. Here, then, is the real explanation of the cause of the equality in the mortality and recovery in the two sets of hospitals:that those who are able to stand the treatment and the disease, get well; and those who are unable, die. The practice of medicine (medendi, curing) turns out to be nothing. All that the physician can do, is to open his wards and see fair-play between Nature and Death. If the struggle between them end in favour of the latter, he has the satisfaction of confirming his diagnosis; if in favour of the former, of dismissing his patient. 6 YOUNG PHYSIC. Is it, then, really come to this-that, after two thousand years of observing disease, we are no further advanced in its treatment? In what respect is Young Physic superior to Hippocrates? They both advise the same thing: Watch, say they, the progress of disease, but do not interfere. Young Physic, however, remarks, that all who have deviated from this rule have done mischief. All that his greater experience has taught him is, to have greater confidence in the canon of Hippocrates. How long is this new cycle to run? Are we to stand, like sentinel-stars, for other two thousand years, silently watching the course of disease, while ever and anon an eccentric man of action suggests some practical innovation, till, at the expiry of this double millennium, another Forbes arises, and with his critical crowbar demolishes the systems of these practical men, and dooms his fellow-mortals to endure all the pangs of sickness, with nothing but the consolations of philosophy to alleviate them? In short, what is the germ of Allopathy on which Dr. Forbes rests his hopes? The only positive recommendations we can find are-carefully to watch the progress of* disease, to employ all proper hygienic measures, and to use the numerical method in noting down the effects which have been or may be observed to follow the administration of the medicines. The first two recommendations, however excellent, can hardly be considered as at all differing from those given by Hippocrates; and as Dr. Forbes evidently expects much good to accrue from the last, it is to it we shall now direct our sole attention: and if we can establish that the only results of such a method are increasing perplexity, rank error, or total disbelief in the powers 'of YOUNG PHYSIC. 7 medicine, we must acknowledge the incapacity of Young Physic to be of any use,-except in the way of a pioneer. "Life is short and the art is long; the opportunity quickly passes; experience is fallacious, and decision difficult:" how, then, can any man, in the short term of his life, discover for himself what remedies are certainly useful in the all but infinite variety of diseases he has to treat? Suppose even that he has the advantage of a large hospital, is it possible for him to make experiments in such a way as to arrive at certain knowledge? The Young Physic school, which prides itself upon its philosophy, recommends the use of the numerical method, that, by noting down the result of each medicine in each form of disease, we may at length arrive at positive data to direct us in future cases. Let us inquire what philosophers of established reputation think of this plan. M. Comte scouts with the same severity as Sir John Forbes, all ontological speculations, and founds his system on the ascertainment of positive phenomena alone, leaving the mystics to pry into the causes of these phenomena. He has, moreover, a profound respect for mathematical science, places it as the first and fundamental science in his scheme of human knowledge, and is most anxious to carry the numerical spirit as far into general science as it will legitimately go. He would apply the method of numerical notation to every department of human knowledge, where it could be of any avail. Surely if any philosopher of note is likely to countenance Young Physic's brave attempt to 'reform medicine by introducing into it the accuracy of arith' Hippocrates' first Aphorism. 8 YOUNG PHYSIC. metic, it must be M. Auguste Comte. His opinion is given in the following words: "Indeed the spirit of calculation tends in our day to introduce itself into this study, (Physiology) especially into that part of it relating to medical questions, by a much less direct method, under a 9~uch more specious form, and with infinitely more modest pretensions. I wish to speak of that pretended application of it which is called the statistics of medicine, from whicl many savans (e.g., Young Physic) expect wonders, and which, from its very nature, can lead only to profound and direct degradation of the medical art, (reduced by it to a blind enumeration.) Such a method, if we may be allozoed to call it by the name of method at all, cannot, in reality, be any thing else than absolute empiricism, disguised under the frivolous garb of mathematics. Pushed to its extreme logical consequences, it will tend to makce all rational medication radically disappear from medicine, by conducting the practitioner to make chance trials of certain therapeutic measures, for the purpose of noting down with minute precision the numerical results of their application. It is evident, on principle, that the continual variations to which all ogyanism is subjected, are necessarily even more pronounced in a pathological, than in a normal state, as a result of which, the cases must be even less exactly similar, whence results the manifest impossibility of making a judicious comparison between two curative methods derived from data furnished by statistical tables alone, independent of some sound medical theory: No doubt some direct experimentation, restrained under proper limits, migyt be of great importance to medicine as well as to physiology, but it is precisely under the strict condition that it shall never be simply empiri YOUNG PHYSIC. 9 cal, but that it shall always attack itself either in its institution or in its interpretation to an entire system of corresponding positive doctrines. (A 1'ensemble systematique des doctrines positives correspondantes.) Notwithstanding the iymposing aspect of the forms of exactness, it would be dificult to conceive of an opinion in therapeutics more superfcial and more uncertain than that which rests solely on the easy computation of fatal and favorable cases, to say nothing of the pernicious practical consequences of such a manner of proceeding, where one could not beforehand exclude any kind of attempt. " It is really deplorable that geometricians have sometimes honoured with some kind of encouragement, such a profoundly irrational aberration, by making vain and puerile efforts to determine, by their illusory theory of chances, the number of cases sufficient to make these statistical results legitimate." 1 We must again remind Young Physic that M. Comte is one of the first of living mathematicians, and one who, more than any other philosopher, insists upon the prolongation of the mathematical method as far forward into the more special and complex sciences as it can be made to go. There can be no greater contrast than that presented by Sir John Forbes, as a destroyer, and as a builder. Nothing can be clearer, more precise, more acute than his objections to the systems or practice of others; but when he makes his own system known, he becomes vague and obscure in the extreme, and falls into declamation about the medical profession being " grand and 1 ' Cours de Philosophie positive,' par M. Auguste Comte. Tome 3me. pp. 418, 420. 10 YOUNG PHYSIC. glorious in its essence, aims, and aspirations!" Wearied, it would seem, with the work of demolition, he sinks into the state described by Horace, when he says, " Auditis? an me Icdit amabilis insania?" and in the dim perspective he sees the future progeny of Young Physic flit past like Banquo's shadowy race, but cannot catch or paint their lineaments. The system which is thus faintly suggested in the article of Sir John Forbes is more fully expounded by Dr. A. Combe in his letter " On the Observation of Nature in the Treatment of Disease." This letter is very remarkable for its candour and high moral tone. It contains also much truth, and shows that the writer, to some extent, perceives the real cause of the backward state of medicine when he says that, " notwithstanding the ardour and success with which facts are sought for, yet, inasmuch as the ultimate facts remain unknown, the others lead to no useful result." If by ultimate fact, Dr. Combe means the largest possible generalisation, and this is the only idea that a disciple of Bacon can attach to the phrase, then we entirely agree with him, but we look upon the homoeopathic principle as being that ultimate fact which he seeks. Although to a certain extent Dr. Combe feels the necessities of medicine, and truly says it is by the ascertainment of an ultimate fact, that is, a general law, that we.can advance our science, yet the means by which he strives to reach the point of vantage are as vague as his general conception of what it would be, when gained, is just and exalted. The system which Dr. Combe expounds is founded on a radical error in philosophy. His view is this:-If we observe the progress of disease, we shall find that it runs YOUNG PHYSIC. 11 a determinate course; it has its origin, its growth, and its decline; in these it obeys certain fixed laws given to it by the Creator. It is for man to learn these laws-to interpret these laws, but not to interfere with them. Nature alone cures, not man. It is presumptuous in man to usurp the prerogative of Nature, and attempt to improve upon her efforts. Man is the interpreter, not the master of nature. Such seems -the general drift of his opinions, which, lest we misstate them, we shall give in his own words;-" The grand object of medicine is to preserve and restore the healthy action of all the different organs and functions of the human body, so as to insure their efficiency, and fit the individual for the successful discharge of the duties devolving upon him as a created being and a member of society. Here, then, the first step to be taken is obviously to become acquainted with the mechanism of the body, the structure of its constituent organs, the conditions or laws under which these act, the purposes which they respectively serve in the animal economy, and the relations in which they stand to each other, and to the external agents by which man is surrounded and acted upon from the moment of conception down to his latest breath. In other words, the first step towards rational principles of cure must consist in a knowledge of the laws of the healthy functions. The second ought to be the observation of the manner in which the various disturbing causes act upon the different functions, and the kind, course, duration, and termination, of the morbid action which they produce. Having investigated these points, we become qualified to inquire, in the next place, what circumstances will best favour the intentions of Nature, and remove the obstacles 12 YOUNG PHYSIC. which may have arisen to impede or thwart her efforts. To succeed in these aims, or even to make a rational attempt at succeeding, we must be profoundly impressed, or, I may say, saturated, with the great principle or truth, that all the operations and actions of the living body, whether healthy or morbid, taking place according to fixed and discoverable laws, and that God has left nothing to chance. With this grand fact before us, it becomes palpably evident that we can do nothing rational in the way of either prevention or cure, except in so far as we act in accordance with those laws. Many medical men have, however, a very different impression from this. A good physician will always seek to be, and never aim at being more than, Bacon's ' servant and interpreter of Nature.' A greater than he created man, and ordained the laws of his being, and no surer road can be found than that traced by the hand of his Creator. Overlooking this truth, and viewing disease as an entity, ungoverned by any definite laws, and not destined to run through any definite course, many medical. men talk as familiarly of their ' curing' and ' arresting disease' as if they had an absolute control over the whole animal functions, and could alter their laws of action at pleasure. To my mind, no clearer proof of presumption and philosophic ignorance can be found than this usurpation of the prerogatives of Deity; and its results are -often very unsatisfactory," The great error contained in this view consists in confounding the so-called laws of Nature with the laws of a moral Creator. The tap-root of the false school of philosophy to which Dr. Combe seems to belong, and which has recently been fully expounded in many popular works, YOUNG PHYSIC..13 is confounding the real obligation of man to obey the.moral laws of his Creator with his assumed submission to the laws of the creation. The so-called laws of the creation have no existence out of the mind of man. They are but the summary expressions of his knowledge; they are but the ultimate facts or laws he has arrived at. " Ultimate laws," says Mr. Mill, "are observed uniformities of Nature which cannot be resolved into more general laws." 1 All that they express, in any case, is the constant relation of certain facts to certain other facts. This is all that gravitation expresses. Because gravitation is a law of Nature, would any sane man argue that therefore it ought not to be interfered with? What is the whole active life of man, but a struggle with this great law of Nature? What is death but a sinking under it-becoming obedient to it-being let down, pulled down, we might say, in submission to this grand natural law? It cannot, then, be argued that because a process occurs in obedience to a law of physiology or pathology, that on that ground alone we ought not to interfere with it. It must be shown that it would be. injurious to the patient if we did. This, which is the only real point at issue between us and the Naturalists, Dr. Combe does not attempt to touch. He shows, indeed, that in certain cases it is very hazardous to use the ordinary depleting measures; but he does not even attempt to show that there are not, or may not be, means which are innocuous, yet potently beneficial. He does not show that there may not be a science of therapeutics, or curing; but he implies, from the position he at first assumes, that there cannot. 'Mill's Logic,' vol. ii, p. 3. 14 YOUNG PHYSIC. Miserable as are the conclusions Dr. Combe arrives at, we believe they are the logical consequences of working out Sir John Forbes' system; and for this reason we attach much value to his letter, independently altogether of the high and generous tone which pervades it, and which gives great weight to its influence over others. If ever Medicine suffer utter degradation, it will be brought about by means of this new school. The leaders of the profession are engendering a scepticism in Medicine which, unless counteracted, will blight it to the core. Practitioners of physic will become divided into two classes,the one believing nothing, but yet acting as if they did, and giving the countenance of their high talents and acquirements to the rankest hypocrisy; the other class believing anything or everything, but having no substantial grounds for their belief: cold, cultivated sceptics will be the aristocracy, and ignorant but energetic dupes of their own credulity the democracy, of this noble and glorious profession. No wonder that one of Sir John Forbes' correspondents exclaims, " What more melancholy fact can be presented to the mere prescriber, when he first enters upon the duties of his benevolent profession with the enthusiasm of unsoured philanthropy, than the continual assurance of the Nestors of the profession, that the greater our experience the more positive our conviction that we can do nothing? And it only proves the immense force of habit that, with such convictions, we do not see men quit a profession which, under such circumstances, requires a constant exercise of hypocrisy and a constant sacrifice of principle." While the great majority of those who have expressed; their opinions on the state and prospects of medicine YOUNG PHYSIC. 15 agree in the main with Sir John Forbes and Dr. Combe, yet a few avow their dislike at being thus consigned to the negative pole of usefulness. The best exponent of the views of this class seems to be Dr. Bartlett, who says, " the seat, the character, and the tendencies of the disease being known, the next thing to be done is to find out the best means of preventing, modifying, and of curing it." To do this he goes on to say, "we must know the effects and influences which all substances and agencies in nature are capable of producing upon it, and this we can know only by direct observation of the effects themselves." That is, we suppose medicine improved by a system of experimentation with individual drugs upon individual diseases. This is what another writer likewise proposes. Let us again apply to some philosopher of acknowledged reputation, to ascertain what may be expected from such experiments when not conducted in the light of some previous theory. It most fortunately happens, that the very case in point is used as an illustration by Mr. J. Stuart Mill, in his work upon Logic. The great modern authority upon. the subject writes thus:-" Let the subject of inquiry be the conditions of health and disease in the human body, or, for greater simplicity, the conditions of recovery from a given disease; and in order to limit the question still more, let it. be confined,.in the first instance, to this one inquiry,-Is, or is not, a particular drug, Mercury, for example, a remedy for that disease?.. When we devise an experiment to ascertain the effects of a given agent, there are certain precautions which we never, if we can help it, onmit. In the first place, we introduce the agent into the midst of 16 YOUNG PHYSIC. a set of circumstances which we have exactly ascertained. It need hardly be remarked how far this condition is from being realized in any case connected with the phenomena of life; how far we are from knowing what are all the circumstances which pre-exist in any instance in which mercury is administered to a living being. This difficulty, however, though insuperable in most cases, may not be so in all; there are sometimes (though I should think never in physiology) concurrences of many causes in which we yet know accurately what the causes are. But when we have got clear of this obstacle we encounter another still more serious. In other cases, when we intend to try an experiment, we do not reckon it enough that there be no circumstances in the case the presence of which is unknown to us, we require also that none of the circumstances which we do know of shall have effects susceptible of being confounded with those of the agent whose properties we wish to study; we take the utmost pains to exclude all causes capable of composition with the given cause; or if forced to let in any such causes, we take care to make them such that we can compute and allow for their influence, so that the effect of the given cause may, after the subduction of those other effects, be apparent as a residual phenomena. These precautions are inapplicable to such cases as we are now considering.... Anythiny like a scienific use of the method of experiment in these complicated cases is therefore out of the question. TWe can, in the most favorable cases, only discover, by a succession of trials, that a certain cause is very often followed by a certain effect." 1 We find, then, that logic as unceremoniously discards the 1 ' ill's Logic,' vol. i, p. 529. YOUNG PHYSIC. 17 experimental method proposed by Dr. Bartlett as philosophy condemned the statistical method sanctioned by Sir John Forbes. Indeed, the two methods are very nearly allied, the one almost involving the other; and if they both be abandoned, and if young physicians be not content with being the mere spectators of disease and superintenders of diet and ventilation, and revolt at the idea of hospitals for the cure of the sick being nothing but museums for the study of morbid natural history, and registries of mortality, to what side are they to turn for escape from the alternatives presented to them? How shall they be followers of nature and yet energetic? How shall they know all that is to be known, and not be sceptical; and do all that is to be done, and not be dangerous? If the simple observation of the natural course of disease; if the application of the numerical method to all recorded cases; if experiments with various medicines upon various diseases, are each and all fallacious modes for the improvement of medicine, what conceivable method yet remains by which it may be raised from its present uncertainty to become amenable to known laws, by which it may be worked? The answer to this we have already anticipated, at the commencement of our article. The accumulation and complexity of facts in medicine rendering the inductive process inapplicable, it is absolutely necessary, for the regeneration of the science, that some successful hypothesis be made which shall express the law of relation between the curative and some other discoverable property of a drug, by which we may know beforehand what we are to select in a given case of disease. There has been but one such 2 18 YOUNG PHYSIC. attempt in medicine, (for we need not stop to show that the old Galenic maxim, " Contraria contrariis opponantur," is not such an hypothesis, involving, as it does, the previous ascertainment of conditions as impossible to recognise as they are incapable of being tested;) that is, that medicines tend to cure diseases similar to those they tend to produce.' This is a perfect hypothesis for the circumstances; because it embraces all the circumstances coming within the range of medication, and it is possible to establish the truth or falseness of it by experiment. How vain and ignorant it is of those who profess themselves philosophic practitioners, to reject this proposition, and to stigmatize the practice thence flowing, on the ground of its being at the first hypothetical, is shown from the fact that all complex sciences have become perfect by means of some successful hypothesis. What was Kepler's law of planetary motion, which has introduced such accuracy into astronomy that the accession of a new member to our system can now be infallibly predicted, but an hypothesis verified by calculation? What was Dalton's atomic theory, which has given such systematic beauty to chemistry, but, an hypothesis verified by calculation? What was Torricelli's grand discovery of the pressure of the atmosphere, which opened a new era in physics, but an hypothesis verified by an experiment? It is the same with Hahnemann's great law of medicine -it is an hypothesis proved true by its results. Had Sir John Forbes and his followers been alive to the necessity of such a discovery, had they perceived 1 We believe this is the most accurate way of stating the law of homceopathy, and it would obviate many objections if this mode of expressing it were generally adopted. YOUNG PHYSIC. 19 that it woas not a Bacon, but a Newton, that medicine stood in need of, they would have formed a very different estimate of the grandeur of homoeopathy; they would not have harped with puerile pertinacity upon the assertion that Hahnemann was mistaken in supposing that the symptoms of ague he felt stood in relation of cause and effect to the doses of Cinchona bark he had previously taken. They would have perceived that it was of very little consequence what gave rise in the mind of Hahnemann to an hypothesis which, if substantiated, would make medicine ever afterwards a deductive science, and not an empirical one; and they would have directed all their energies to ascertain whether this hypothesis be true or false; for if true, it must change the whole character of the art. There were three possible ways open for disproving the truth of homceopathy: first, by showing that it was opposed to some already established natural law; second, by showing that the facts on which it rested its claims for belief were either false or too few; third, that when tried as a guide in practice, it led to failure. The first way was never attempted. No one has yet ventured to assert, that the proposition that a medicine tends to cure diseases similar to those it tends to excite, is.radically opposed to any general fact. On the contrary, were this the place for it, it would not be difficult to demonstrate, that this primary law of homoeopathy presents many striking and interesting analogies with some of the most important doctrines that have recently been advanced by the greatest writers in the various fields, of physics, ethics, and psychology. Neither Sir John Forbes, nor any of his school, have 20 YOUNG PHYSIC. devoted themselves to the task of undertaking the second way, and showing that there is not a marked similarity between the curative and noxious effects of very many drugs. Nay, Sir John Forbes himself admits, in these words, that there is such a resemblance. " Indeed, it is supported by several strong analogies, afforded both by pathology and (allopathic) therapeutics." The only other way which remained was to show, that where this law had been applied for the cure of diseases, it had entirely failed to effect its object. How far our opponents have succeeded in this, we leave those to determine who have carefully and critically studied Professor Henderson's letter to Sir John Forbes, as well as the evidence from which his arguments are drawn. Hitherto we have contemplated homoeopathy as an abstract scientific truth, " won from the void and formless infinite," by the genius of its discoverer; a truth which would remain the same, although disease were to disappear, and there were no occasion for its application to human affairs; and we have considered the reason why the value of this truth has not been appreciated by the foremost men in our profession. But between such an abstraction and the requirements of daily life, there lies the province of art. The truth might be revealed, but might remain for ever unprofitable to us, if we were not instructed in the mode of its application. Art is to science what action is to thought. The discovery of the law of homceopathy made medicine as a science perfect; it required another discovery before an element of perfection was imparted to medicine as an art. Discoveries in art are of a wholly different kind from those in science. YOUNG PHYSIC. 21 They are simply empirical rules obtained from observations or experiment, and proved true by experience. They never can have the same absolute value as fundamental scientific principles, nor are they susceptible of the same amount of proof. The rules of art occupy, as it were, a middle point between science and its application. They rest upon a surface of fluctuating observations, and they derive their coherence and stability from a source different from that of their origin. That source is the abstract scientific truth to which they are united. In estimating the value of these rules of art, it is necessary always to keep in view this their double connection; and it would be as unfair to judge of them, separated from the scientific principle which gives them support, as it would be to insist upon a child living in its mother's womb after the umbilical cord had been divided. This is the injustice which has been practised upon the rule of art connected with the science of homceopathy;-the rule that medicines when administered in accordance with the principle " similia similibus," should be given in minute quantities. If the proposition had been advanced that medicines, in doses infinitely minuter than had ever hitherto been imagined, were capable of curing diseases, as a simple fact of observation, it might fairly have been met with the ridicule that has assailed it. But when advanced under the protection of a more general proposition, it ought to have been always viewed as related to this general fact; and in that light, whether it be true or false, it ceases to be ridiculous. While, then, we charge Sir John Forbes with committing a fundamental error in philosophy, by not appreciating the necessity of some general hypothesis by which 22 YOUNG PHYSIC. the science of medicine may be made deductive, we charge him and his followers with a second error in judging of a rule of art without taking into consideration the cognate scientific principle from which it derives half its force. This misapprehension of the properpoint of view, from which the system of giving small doses ought to be regarded, on the part of all English writers, is the less excusable, since those who have adopted their side of the controversy in Germany, have admitted and given full prominence to the fact, that the dose must vary according to the principle by which the medicine is selected. "' On the other hand," observes Dr. Jorg, " medicines operate most powerfully upon the sick when the symptoms correspond with those of the disease. A very small quantity of medicinal arnica will produce a violent effect upon persons who have an irritable state of the oesophagus and stomach. Mercurial preparations have in very small doses given rise to pains and loose stools, when administered in an inflammatory state of the intestines. Yet why," he exclaims, " should I occupy time by adducing more examples of a similar operation of medicines, since it is in the very nature of the thing that a medicine must produce a much greater effect when it is applied to a body already suffering under an affection similar to that which the medicine itself is capable of producing?"1 Another great error which the various writers upon the subject have fallen into, when treating of minute doses, is confounding the amount of force required to originate a series of changes in the animal system, and that which 1 Materiellen zu einer kiinftigen heillmitellehr& durch versuche der Arzneien an gesunden Menschen gewonnen und gesammelt von Dr. Johan C. G. Jorg, p. 16. YOUNG PHYSIC. 23 is required to modify those changes where already going on. It is, if we may so express it, applying to a question of dynamics, calculations derived from data afforded by statics. Contented as the disciples of Young Physic are with allowing morbid processes to proceed without any intervention, and simply supporting the powers of life, that the system may not sink under the continuance of the disease; and accustomed as they and all allopathic physicians are to look upon therapeutic agents as operations beyond, or outside of the actual morbid forces, (the derivative system of medicine,) they do not perceive that if it be possible to introduce a force within the actual sphere of diseased action, that force will be incalculably intensified in its operation by acting on other forces already in a state of preternatural and violent activity. A breath of air will deflect an arrow from its course, although shot from the bow of Apollo. We do not intend to dwell upon the point last mooted, partly because our space is exhausted, and partly because it has already been fully and ably handled by various writers, especially by Dr. Henry Madden, in a work entitledC 'Reformed Medicine.' Before we close this fragmentary paper, the design of which has been rather to discover, if possible, and to indicate the chief sources of the errors of our opponents, and in this very search to point to the refutation of those errors, than to expose, by argument, the numerous fallacies which have marked their winding course throughout the controversy, we wish to do full justice to Sir John Forbes. We look upon him as the ablest exponent of the sceptical era in medicine. He expresses for the Medicine what others have done for the Philosophy of 24 YOUNG PHYSIC. our period, which has been characterised as " an age of unbelief, and yet afraid of scepticism." By giving expression to prevailing scepticism in medicine, Sir John Forbes has rendered an immense benefit to the profession; he has brought out and made czurable the hitherto latent psora. The element of faith which he would fain mingle with his confession of general unbelief is too foreign to the rest of the system to have any influence upon his disciples. The reform he has so powerfully advanced will soon become a revolution beyond his power to control. -His influence for the future will be purely destructive. But destruction of the bad must precede construction of the good; and for having with great talent and boldness attacked and shaken a dynasty whose speedy termination is with certainty predicted by this revolt of its chief supporter, as the doom of the Corn Laws was pronounced by the leader of the party which had maintained them-for having rendered this service, and opened the gate of scepticism for the admission of truth, we feel deeply indebted to him, and we have no doubt that his school will prove to many the halting-place between old physic and homoeopathy; and the title of his great article should be, not ' Homoeopathy and Young Physic,' but HOM(EOPATHY via YOUNG PHYSIC. CHAPTER II. ON DIET. WHETHER it be true, as some historians affirm, that Napoleon lost the battle of Leipzic owing to his having eaten a bad dinner, is certainly questionable; but there can be no doubt whatever that bad dinners and bad food generally are at the bottom of much domestic and national misery and disaster. And there is no subject which more imperatively demands special attention than the one we are about to enter on. For from the promulgation of the system founded and taught by Hahnemann, numerous specialities in diet have been inculcated with more or less rigour by himself and his followers, and so prominent have these innovations become to the eye both of the public and the medical profession, that while the former frequently seem to suppose that if they only consume a sufficient quantity of homoeopathic cocoa, they will be entitled to all the benefits of the new system of medicine, the latter discovers with its usual sagacity, that although the success of our treatment is beyond dispute in very many cases, yet that we owe our superiority, not to the total difference of the principle according to which we select our remedies, but to our better judg 26 )T I. ment in the regulation of the diet of our patients; although the subject of diet has been one carefully studied and ably handled, since the time of Hippocrates, and although by this assumption our opponents pay us the highest possible compliment, by yielding us the palm of victory in the field common to us and them. In fact if they are right in this explanation, it would be tantamount to saying, that as there is no law by which we profess to be guided in our choice of food analogous to that which directs us in the choice of the proper medicine, each individual who practises homceopathy displays a higher amount of intelligence than his allopathic brethren, and is in their sense of the term the better physician of the two. This is a fatal argument for young physic, which professes rather to cure diseases by diet and regimen, than by medicines. They acknowledge themselves thrown in their own ring: how strange is their inconsistency! It is considered disgraceful to admit the superiority of homceopathic medicine, a novelty which old physicians might pardonably plead ignorance of, and they prefer to proclaim their inferiority in the only branch of the physicians' art on which they build their reputation; while on the other hand we find among ourselves a pertinacious adherence to certain dietetic formulas, which rest on no authority but that of accidental prejudice, and which derive no support from the enlarged experience that we have now within our reach. There are but two methods by which we can hope to arrive at any thing like unanimity in our dietetic creed; the one is to assume Hahnemann's writings as our Leviticus, and to ban all he banned, and admit all he admitted; or to inquire into the principles by which he DIET. 27 was directed in the rules he lays down, and to follow out these principles, if they be sound, into their full development by all the lights which modern science and observation have shed upon the subject. As Hahnemann did not assume the infallibility of inspiration, we may safely decline accepting any Leviticus at his hands, and examine with that care and respect which all his writings deserve, what they contain "upon the subject of diet, and we shall be satisfied that if in some instances he was led into extravagance and error, yet that the principles of his doctrine are eminently sound and sagacious. In endeavouring to form a just valuation of Hahnemann's dietetic rules, we must bear in mind that before he had discovered his grand formula for the selection of medicines, he had already written extensively upon various topics connected with diet and regimen, and that he carried over into the new province of homceopathy, where he so long ruled supreme, some of the old adopted notions which he had already too vehemently expressed to admit of his recanting them. The most striking illustration of this was his antipathy to the use of coffee. "The cold, considerate earnestness of our forefathers," such are Hahnemann's words, "the firm stedfastness of will, of resolve and of judgment, the endurance of continued and yet powerful exertions of the body, adapted to the object in view, that used to constitute the original national character of the Germans, the whole sublime stamp of our descent disappears before this medicinal beverage, and changes into over-hasty disclosures, hurried resolves, immature judgments, frivolity, changeableness, talkativeness, irresolution, too 28 DIET. easy mobility of the muscles without any endurable result, and theatrical behaviour."' The extravagance of this passage makes it read like a temperance lecture. In fact what truth is in it is certainly applicable to the abuse not the use of coffee. It would be interesting if we could discover the origin of this excessive hostility to coffee, which belongs to the family of narcotics, and is a sort of foster-brother of tobacco, that "foul and loathsome weed," as an irreverent lecturer calls it, which Hahnemann is said to have loved, if not wisely, at least too well. It may have been an idiosyncratic dislike, or more probably he fell into a common opinion of the time in which he wrote, and which was strongly shared by the philosopher Kant,2 and by many French physicians, that coffee was an injurious beverage, and he afterwards rested his opinion upon the basis of unsound experiment. That it was an unsound deduction from the effects which follow the use of coffee when taken in a way to produce derangements in the system, to forbid its use in all circumstances, is obvious, if we reflect that we could all make ourselves as ill as many of our patients, if we were only to take dinner at time of breakfast, and tea at dinner time for a few days. We cannot, however, dismiss the subject of experiments in diet, without some further remarks. And the first is, that although in the particular example we have quoted, Hahnemann committed a great mistake, yet that on the whole he is perfectly sound, and does not seek to lay down any positive rules about diet, but acknowledges that food must be regulated by the special appetites and Lesser writings, Dudgeon's translation, p. 458. 3 See De Quincy's 'Last Days of Kant.' DIET. 29 instincts, as well as circumstances of those who take it; and he gives in his 'Friend of Health' several illustrations of the superiority of the popular over the scientific judgment upon this point. In the whole of his intellectual career he seems to have been looking for some law of relation between diseases and their curative specifics, but nowhere does he hint that there can be any such law to guide us in the choice of food; and as an obvious corollary to this tacit conviction, while he from the first insists upon the necessity of instituting a series of rigid experiments to discover the effects of a drug upon the animal economy, he nowhere suggests that similar experiments should.be made in regard to food. He seems to have recognised the important difference between that kind of knowledge which we reach by experiment, as in chemistry, and that other kind which we gain by observation, as in geology, where nature has made the experiments for us, extending over incalculable surfaces of space and periods of time. The feeding of the human race has been going on in every conceivable circumstance for many thousand years. In the language of Schleiden "The Gaucho who in the wild pampas of Buenos Ayres, managing his halfwild horse with incredible dexterity, throws the lasso or bolus to catch the ostrich, the guanacho or the wild bull, consumes daily from ten to twelve pounds of meat, and regards it as a high feast day, when in any hacienda lie gains a variety in the shape of a morsel of pumpkin. The word bread does not exist in his vocabulary. The Irishman, on the other hand, regales himself in careless mirth on his potatoes and point, after a day of painful labourlie who cannot help making a joke even of the name he 30 DIET. gives to his scanty meal. Meat is a strange idea to him, and he is happy indeed, if four times a year he can add a herring to season the mealy tubers. The hunter of the prairies lays low the buffalo with sure bullet, and its juicy, fat-streaked hump, roasted between two hot stones, is to him the greatest of delicacies: meanwhile the industrious Chinese carries to market his carefully fattened rats, delicately arranged upon white sticks, certain to find a good customer among the epicures of Pekin; and in his hot smoky hut, fast buried beneath the snow and ice, the Greenlander consumes his fat, which he has just carved, rejoicing over the costly prize, from a stranded whale. Here the black slave sucks the sugar cane and eats his banana-there the African merchant fills his wallet with sweet dates, his whote sustenance in the long desert journey-and there the Siamese crams himself with a quantity of rice from which a European would shrink appalled. And wheresoever over the whole inhabited earth we approach and demand hospitality, in almost every little spot a different kind of food is set before us, and the daily bread offered in another form."' After perusing such a passage as this, we naturally ask, what conceivable advantage could the world derive from the experiments of Dr. Stark, who contrived to kill himself in about six months, by a succession of simple dishes? Before his promulgation of homoeopathy, Hahnemanni, with the exception of his disapproval of coffee, did not differ in his views on diet from other writers of his age and country. " There is not," he says, " and cannot be 1 The Plant-a biography, in a series of popular lectures, by M. J. Schleiden, Professor of Botany in the University of Jena, &c. DIET. 31 anything, which, as a general rule, is absolutely wholesome, or unwholesome, * * * * None of the general maxims of the dietist can be accounted good: such as, veal is the most wholesome butcher's meat, &c. * * * * There is a time for everything, says Soloman, and to my mind he speaks much more sensibly than most of the dietists."' There is much more to the same effect in his early writings. It is a very striking fact, that whereas, before he had discovered and taught the great law of healing, his position in regard to medicine, was very similar to that of young physic of the present day, and he relied much upon sanitary and dietetic rules; after he had made good his grand discovery that the obstacles to certainty in medicine were not insuperable, the power of diet as a method of cure, and its general importance seems to have assumed a very insignificant value in his eyes. What before had occupied whole treatises, now shrinks into this solitary observation in the ' Organon,' (p. 308.): -" Considering the minuteness of the doses necessary and proper in homoeopathic treatment, we may easily understand, that during the treatment everything must be removed from the diet and regimen which can have any medicinal action, in order that the small dose may not be overwhelmed and extinguished, or disturbed by any foreign medicinal irritant." In a note he adds, "Coffee, fine Chinese and other herb teas, and many other things ought to be avoided by patients, as they should avoid excesses in eating and drinking, sitting up long at night, damp rooms, penurious living, and so forth." The note concludes with the following remark. SLesser Writings, page 227. 32 DIET. " Some of my disciples seem needlessly to increase the difficulties of a patient's dietary, by forbidding the use of many more tolerably indifferent things, wticl is not to be commended." Here we have the common sense rule laid down, that patients are to avoid things hurtful to themselves, and likely to interfere with the operation of a minute dose of medicine. On this note of things to be avoided, have been built, with a somewhat slavish adherence to the text instead of the spirit, the majority of those homoeopathic diet tables, which are in such large circulation, although some of the most acknowledged authorities have expressed an opinion in favour of a more liberal interpretation of Hahnemann's doctrines upon this subject. Thus Hartmann remarks, " Every intelligent physician will at once perceive, that every patient cannot be subjected to such a rigorous diet, and that a man of sixty years old, for instance, who had been in the daily habit of taking coffee, tea, wine, brandy, or of smoking tobacco and using snuff, cannot be suddenly deprived of those things without detriment to his organism. Hahnemann allowed smoking and snuff; he forbade wine, brandy, and coffee with great severity. This seems inconsistent, and leads to suppose that in a more advanced age we may except some other things from the general rule of abstinence." While in this country2 there is undoubtedly a disposition to enlarge the table of our patients, in America our energetic friend Dr. Hempel seems inclined to surpass Hahnemann in the rigour of his regulations-one of his golden rules, as he styles them, running thus:-" Avoid all stimulating drinks, brandy, beer, wine, and content S 'Acute Diseases,' vol. i, p. 82. 2 See Laurie, Chepmell, and others. DIET. 33 yourself with cold water, milk, light and unspiced chocolate, weak black tea, and syrups made of currants, raspberries, strawberries, or other kinds of wholesome and unmedicinal fruits. Never use tobacco in any shape, except for medicinal purposes."' We suspect that beyond the confines of the State of Maine Dr. Hempel's gospel will hardly find believers in the land of liberty and tobacco. Setting aside all extravagances, the subject assumes a very simple form, and may be divided into two questions. 1st.-Is it possible for our patients to avoid all medicinal substances in their diet; and 2d.-Is it conducive to the better action of the medicine, to enforce a very rigorous diet. At present, let us observe, we are considering the question solely in the view of its relation to homceopathic medicine, not to general health. 1st.-Is it possible to confine our patients to a nonmedicinal diet? Suppose we restrict them to a prison fare, and desire them to drink a tumbler of water, and eat four ounces of bread for a meal, and repeat this three times a day. This would appear simple enough with a vengeance. We shall suppose the scene London, and just inquire into the character of the bread and water diet we had prescribed. To begin with the water, it is an incontestible fact, that, in the words of Dr. Hassall, "The waters at present in use in this metropolis are all hard, and have all the disadvantages of hard water; they are moreover river waters, and for the most part contami1 Hempel's 'Organon,' p. 31. 3 34 DIET. nated to a great extent with organic matter, dead and living; add to these points the fact of their further deterioration by contact with lead cisterns, and by the accumulation and growth of animal and vegetable productions, which take place in these receptacles, and the case is proved against the whole present supply of the metropolis."' It is indeed impossible to contemplate the world of monsters contained in a drop of London water, without being satisfied that a score of globules would go but a little way in affording them a satisfactory repast. Besides these living impediments to the action of our globules, and besides the lead derived from the pipes and cisterns, which will be a stronger dose of Plumbum than our rigorous dietists ever employ, there are no less than from 20 to 30 grains of inorganic matter, carbonate of lime, of magnesia, &c., in every gallon of London water.2 So much for our patient's morning draught of pure water-now for his slice of bread. Dr. Hassall examined twenty-four samples of bread, obtained indiscriminately in various parts of London: his verdict is, that the whole twenty-four samples were adulterated with alum. But perhaps it may be said, the quantity is trifling; on the contrary, according to another observer, Mr. Mitchel, in ten loaves there were no less than 819- grains of alum discovered. And the reason for the presence of alum heightens the enormity of the pollution. It is put there to enable spoilt flour to be mixed with sound flour! 'Food and its Adulterations,' by Arthur Hill Hassall, M.D., p. 52, ct seq. 2 Johnston's ' Chemistry of Common Life,' p. 38. DIET. 35 With such facts staring us -in the face, would it not be absurd to insist upon bread and water as a simple diet for any unhappy patient who has the misfortune to fall into our hands. Unless we could keep our patients in a conservatory, and prepare by artificial means the air they breathe, the water they drink, and the food they eat, it would be absolutely impossible to prevent them being assailed by so-called medicinal influences every hour in their lives. In fact, all nature would be in a conspiracy against them, to avenge the sentence of outlawry we should thus have pronounced upon her. This is the answer to the second question. For if we strive to attain as near as possible a supernatural immunity from the influences at all times powerfully acting upon the human organism by any method of isolation or abstinence, we thereby intensify in a corresponding degree the sensitiveness of the frame, and our patients reared in a hot-house fade away before the first breeze, which had they been of out-door growth, would have invigorated instead of destroying their tender natures. Is there then to be nothing peculiar in homoeopathic diet, and are there no rules to be enforced? The only rule, and we may enforce it with peculiar rigour, that I can conceive as universal, is, that every one should eat and drink what his own experience has taught him agrees best with him, and we on our part need not be at all afraid of the efficacy of our medicines being seriously impaired by what contributes to the well-being of the individual. It may seem very strange to order a dose of Capsicum to a man who dines upon curry. But is it more strange than ordering a dose of Calcarea to a man who drinks a thousand times the amount of the dose in -36 DIET. every glass of water? These are both strange, but life is stranger still, and we are utterly unable to unravel the complex influences on which its integrity depends, and we therefore cannot understand how powerfully substances act in their curative sphere of operation which are quite inert in their nutritive. If we were to throw out a conjecture, it would be that the medicinal action of a substance resembles a distinct impulse upon the nervous system like a note of music, and as an impulse, that is purely dynamically, takes effect, _whereas the same substance conveyed through the system for the purpose of nutrition, does not secure the attention of the nervous system at all. Be the explanation what it may, fortunately for the possibility of our method of practice, the fact admits of no doubt, that infinitely minute quantities of a body produce important effects, while at the same time large masses of the same are quite inoperative, and therefore it is not necessary on the theoretical ground, to insist upon abstinence from all stimulants and condiments as the indispensible initiative to a successful course of homoeopathic treatment. I am aware that these views will be considered by many as somewhat heretical, and perhaps as too speculative, but although I would now rest them upon the reason of the thing, they were forced upon me slowly by my own observations in practice. It is now many years ago since I had a curious illustration of the possibility of a minute dose succeeding, even although the system was at the time being stormed at by massive ones. A patient of mine who had long been liable to megrim, was always cured by a few globules of Pulsatilla. She was also subject to ague, imported from India, which I DIET. 37 could not cure. So she was put under the old system, and ordered full doses of the Sulphate of Quinine. While taking this, she had an attack of her old headache, and took a few globules of Pulsatilla, but expecting nothing from it; for I had told her, so long as she was taking her Quinine it was impossible homoeopathy could do her any good. Homceopathy, however, showed itself more liberal than its practitioner, and after a single dose of Pulsatilla she got better. This case made a deep impression on my mind, and I often thought from that period that perhaps our diet code was too rigorous. Then during a long course of observation, extending over some eighteen thousand cases treated at the Edinburgh dispensary, I found that it was on the whole impossible to interdict successfully the use of tea and spirits, and that notwithstanding these infractions, and a thousand other disadvantages, the proper medicine produced its expected result with so much exactitude as to reduce to an insignificant point the deranging influence of these condemned enjoyments. And quite lately I had under my care a gentleman who took a wineglassful of Laudanum daily, and yet was as speedily relieved by the proper medicine when attacked by pain and spasms of the heart, from which he suffered in consequence of organic cardiac disease, as if he had been an absolute teetotaller. These facts, and many more such could be adduced, ought at least to make us pause before we lay down any imperative rule against the use of coffee, tea, tobacco, and other excisable articles, as being necessarily destructive to the efficacy of homceopathic medicines. For my own part I seldom now make any change in a patient's diet out of respect to homceopathy. And with these 38 DIET. observations we pass on to the more general part of our subject, and consider the principles by which we are likely to be assisted in advising our patients in reference to the most difficult affair of regulating their food and drink so as best to lead a long, healthy, and happy life. The difficulty that meets us at the very threshold of our investigation, and which we cannot get rid of throughout its whole course, and which seems to be strangely overlooked by most professed writers on the subject of the food of man, is, that man occupies an exceptional position in the animal kingdom: although in it, he is not of it. The fundamental instinct of animals is the preservation of their life, and the escape from death. The idea of manliness is contempt of death. The preservation of life is frequently a secondary feeling in man. The reason is, that upon the animal life of man is erected a life of sentiment, emotion, and imagination, which always modifies his animal instincts, and sometimes entirely supersedes them. Hence come the long fasts and vigils of the saints of old, and of the modern Fakirs in the east. Fasts implying a continuance of abstinence from all food, which modern physiologists, deriving their knowledge from the effects of starving dogs and birds, and from the enforced abstinence of shipwrecked mariners and buried miners, insist upon ignoring, as they are so opposed to the conclusions of their experiments and observations. But the testimony in favour of these long spontaneous fasts is as trustworthy as any in favour of the other class, and certainly deserves attention, especially as it shows us a little farther into an every-day occurrence, that is, the power of abstract thinking, or very strong emotion, to DIET. 39 arrest more or less the animal functions. It is the most common observation, that thought is incompatible with violent muscular exertion. Who ever heard of a mathematician trying to solve a problem in the hunting field? If he were found there at all, it would be to escape from thought. When thought is both very prolonged and very intense, and confined to one object, it may induce a kind of trance, in which there is an entire cessation of all other vital action; but long short of this, there can be no doubt that the over-active brain monopolizes the vital energy, and paralyses to a greater or less extent, the other portions of the nervous system,.and cuts off the supply of cerebral stimulus required for the nutrition of the body; that is, which enables the capillary vessels to exercise their elective affinities as to what they shall absorb, and what they shall reject. Nutrition then, or the continual action and reaction of the living world within upon the chemical one without, depends upon two factors, the one the nature of the materials presented to the body to be incorporated into it, to increase its bulk by growth, or to repair its decay, and the other the reception given by the body to these substances presented by the hand of external nature. The character of this reception depends, among other modifying circumstances, upon the state of the mind, and the whole doctrine of the fitness of aliments f6r their proposed end, must begin by assuming that end to be known. Hence the grand difficulty of laying down laws upon the subject, for the ends of life are so dissimilar in different men. The scale runs from the sensualist, whose avowed end is corporeal enjoyment, to the ascetic, whose object is bodily morti 40 DIET. fication. And it is the duty of a physician to appreciate all these varities, and to administer advice, not according to his own preconceived notions of the proper ends of life in general, but the most healthful, or least injurious method of securing for each person his peculiar, if innocent object of desire. If we were practising in the millennial times, we might tell men to avoid all excess, of eating, drinking, loving, hating, sleeping, waking, working, talking, &c.; perhaps when such advice can be followed, it will not be needed; certainly to talk so to men as they are now, would be in many cases simply an impertinence, or an affront. What would become of a popular preacher if he could not fill a large church with his voice for an hour together, or a popular alderman, if we forbade him to taste turtle? In short we must make the best of our materials, accommodating our rigging to the state of our vessel, and sometimes too thankful if we can secure a jurymast to save our ship from impending wreck. After these preliminary remarks, let us consider how our bodies are built up from day to day, and of what materials the structures consist. " According to Quetelet, a full grown man weighs on an average 154 lbs., and if we substract the great quantity of water which runs through all parts of our body, keeping them supple and pliant, some 38 lbs.; 14 lbs. of this comes from the bones, and 24 lbs. from all the remaining parts. The former contains about 66 per cent., the latter 3 per cent. of earthy constituents which are left behind after combustion. Man consists, therefore, in more than a third part, of inorganic substances which are necessary to his existence, and which he must there DIET. 41 fore receive with his food. He must in fact as the evil spirit says in Faust, 'feed upon dust.' "1 It is to supply this dust for the stony skeleton of the fabric, that birds instinctively swallow sand and gravel, and not to assist the comminution of their food merely. Chossat found that birds deprived of sand, and fed upon grain, died in seven or eight months, and the bones became so brittle, that they broke with the slightest touch. Total abstinence from salt, the constituents of which enter largely into the composition of the blood, is productive of various evils, among which, according to Woodward, scurvy is one of the most remarkable, and Dyer ascribes the frequency of tapeworm in the negroes, who eat but little or no salt, to the same cause. The necessity of salt is greater if the food be of vegetables, as less is contained in them than in animal diet. In strange contradiction to these well-authenticated facts, accepted by so cautious and critical a writer as Moleschott,3 stands the extravagant nonsense of one of the apostles of abstinence, Mr. Sylvester Graham,3 that "salt is a mineral substance, and is wholly innutritious and indigestible." Does this gentleman, and do those who crusade with him against the traditional symbol of hospitality, ignore the fact that bones are necessary, and that without mineral and innutritious articles of food we cannot have them? Besides the salt we take with our food, we obtain a 1 Schleiden, op. cit. 2 'Die Physiologie der Nahrungsmittel, ein Handbuch der Dietetik,' von Dr. J. Moleschott. 3 'Lectures on the Science of Human Life,' by'Sylvester Graham, People's Edition, p. 270. 42 DIET. large quantity of mineral substances from the water we use so copiously in all articles of consumption, even if we do not indulge in libations of the limpid element. And it has been observed that waters artificially deprived of their saline ingredients are unfit for domestic purposes. The phosphates, however, we must get either from. animal food, or from grains, in which they exist in considerable quantity, and Mulder ascribes the frequent fractures he observed in a poor-house, to the exclusive potatoe diet. This disposition was rectified by giving the inmates rye-bread and butcher's meat, and the hint may be useful in dealing with various conditions met with among our own poor. There is no great difficulty in comprehending how the inorganic materials are used in building up the body, for they undergo no other changes in it than those ordinary chemical de- and recompositions we are familiar with in the laboratory. The component mineral matters of the bones and other parts are all found in the blood, into which they are conveyed by the chyle the product of the food, and out of the blood they are selected by the capillaries of the bones according to laws of vital affinities of which we are totally ignorant. But this we do know, that it is now an ascertained fact, that there are no transmutations of elements in the body, that if phosphorus and iron are found in the blood, they must be previously discoverable in the food, and that there is not a -tittle of evidence for the assumption that out of silica iron can be made, or out of oxygen phosphorus. So much for the inorganic components of our frame. A much more difficult task is the description of the organic remainder. This has been divided into those DIET. 43 substances which contain nitrogen and those which contain none. The nitrogenous elements (using the word element in a larger sense) of food are chiefly albumen, as it presents itself in the white of egg, or, in a slightly modified form, as it exists in the blood; fibrin, whether as found in blood, or in flesh, and caseine, or cheesy matter. Vegetable albumen, fibrine, and caseine, are identical with the animal substances so named. Gelatine, though'nitrogenous, is generally considered not to be truly nutritive, as it cannot form blood; but it may form membrane, and so assist in nutrition. The non-nitrogenous elements are chiefly starch, sugar, and fat, in their various forms. Let us then proceed to consider how we obtain these substances, and what changes they undergo during their strange metamorphosis-we might almost say, without irreverence, their miraculous transubstantiation -from dead dry bread into living juicy flesh. Before doing so, however, it may be well to point out the enormous importance of the facts just mentioned, that the body imperatively demands for its health a supply of certain mineral substances, among which soda and phosphorus hold an important place, and that various forms of disease, such as scurvy and softening of the bones, are the consequence of starving it in this direction. The obvious deduction for us is that to cure such unsound states of body, it is as essential to feed it with what it wants, as it is to give food to a famished man. Here we touch upon one of the limits of the application of the homceopathic or any possible therapeutic formula. Diseases arising from insufficient supply of any of the constituents of the frame, cannot be cured by any medicine whatever, and can only be cured by giving in some 44 DIET. form or other the required aliment. This holds true, as was first demonstrated by Boussingault,1 for the vegetable kingdom, and upon this fundamental law of nutrition the whole modern system of agriculture is based; and in consequence of the violation of this law, and growing potatoes upon a soil richly manured, arose the potato-disease, so eventful in its social and political consequences.2 Let us resume the previous enquiry as to the means by which the body gets its supply of nitrogenous ingredients. The answer will be sufficient if we can trace them into the blood, for the blood is the body in a fluid state; nothing is found in any part of the animal frame which does not exist, in some form or other, in the blood. We must begin with an analysis of this allimportant fluid. The nitrogenous constituents of the blood are: 1st. Albumen, of which, according to Becquerel and Rhodier, there are from 71 to 87 parts in a thousand. Salts of phosphate of lime, of sulphate of potash and soda, and chloride of sodium, are intimately mixed with this albumen, which, according to the formula of Mulder, consists of N"s CGs8 O0 S8 P00 2d. Fibrine, which differs chemically from albumen, chiefly in containing more oxygen and less sulphur. Mulder's formula for it is N8s C67 H53 O' S T P. The quantity of fibrine varies from 2*1 to 2-8 parts in a thousand. ' Rural Economy in its relations with Chemistry,' &c., by J. Bonssingault. 2 See Johnston, op. cit. DIET. 45 3d. Caseine. A substance of a very complicated chemical nature, and found in a very small quantity in the blood. 4th. Globuline. A very important constituent, forming the white membrane of the blood-globules. It differs in many of its chemical aspects from the albumen, fibrine, and caseine, and according to Le Cann, amounts to 125"6 parts in a thousand. Mulder's formula for it is N94 C694 H522 S6. 5th. Hsematin, on which the colour of the bloodglobules depends. It amounts to about 2-3 parts in a thousand, and its most interesting feature is its peculiar chemical nature, for it contains neither sulphur nor phosphorus, but consists of N3 C1 H22 Fe. Hence the necessity of iron for the proper nourishment of the body, and especially for the ruddy glow of health produced by the rich red blood. Such, then, are the nitrogenous constituents of the body, which we must supply it with to preserve life and health, and we shall now consider whence the supply is derived, and in what form, and what changes it has to undergo before it is converted into this liquid flesh and bone. The supply must come from either the vegetable or animal kingdom, for although we read of tribes who consume as their chief food large quantities of elay, yet it is now a recognised fact, that unless the clay contain animal or vegetable matter in some form, it may be merely as a multitude of those infusoria Ehrenberg describes, it is in itself as clay, or mountain meal, or any other merely mineral substance, incapable of sustaining 46 DIET. life, although for a time it may appease the cravings of hunger. Let us turn then to the vegetable and animal kingdom, and set out with this important observation of Mulder, " that those who feed on flesh, and those who feed on vegetables, partake of the same nutriment; they have both their albumen, the one derived from plants the other from animals, but for both the albumen is the same."1 It is obvious that the albumen, and its modification gelatine, which we derive from our animal food, requires less transformation to prepare it for returning to a condition almost precisely similar from that which it had previously held, than the vegetable albumen does to enter for the first time the portals of animal life. Indeed, all that it needs is to be dissolved, and this is done, first by the processes it undergoes in the kitchen, which holds to man somewhat the same relation that the first stomach or paunch does to ruminating animals; next by the mastication and insalivation it is subjected to in the mouth; and lastly by the solvent action of the gastric juice, which according to the observations of Beaumont on the Canadian, Alexis St. Martin, the operations of whose stomach were open to inspection by an accidental perforation, takes from two to three hours to dissolve an egg. Albumen is first coagulated, and then dissolved by the gastric juice; gelatine is simply dissolved, and thus passed onwards, as chyme, to be absorbed into the blood. The nutritiousness of animal food is generally 1 G. J. Mulder en W. Wenckenbach, ' Natur-en Scheikundig Archief.,' s. 128, quoted by Moleschott. DIET. 47 calculated by the quantity of albumen it contains, and hitherto there has been a disposition to consider that gelatine only afforded material for cartilage and bone, and not for muscles. This opinion rested upon some experiments of the French commissioners appointed to investigate the qualities of different aliments, who succeeded in starving dogs by giving them nothing but pure gelatine to eat. However, these experiments, at once unphilosophical in their conception and cruel in their execution, are entirely refuted by the fact, that dogs not only lived, but throve and fattened upon a diet consisting of nothing but bones; a fact corroborated by the history of every convalescent, who is nourished by arrowroot and pure soup, as Mulder remarks.' Why dogs thrive upon bones, and starve upon the pure aliment the bones contain, is a problem of which there are many examples, some of the most curious are several instances where horses on a voyage pined away under the exclusive use of grain as food, and, impelled by the instinctive requirements of their organism, tore and eat all the dry wood within their reach; on this hint they got chips of wood, and very soon recovered their flesh and spirits.2 From this we gather, that the vital processes, as well as the chemical products, are necessary for the maintenance of health, and it should make us hesitate before we subscribe to any diet-table submitted to us by the chemist, unless it be in accord1 It is right to observe that this view of the utility of gelatine is not generally accepted by chemists, who say that both bones and soup contain other matters besides gelatine, a substance they consider incapable of forming blood, and consequently of sustaining life. 3 Graham's c'Lectures,' &c. DIET. 49 is, that he employed mixed substances in his experiments, and also that with him solution, or rather, reduction into a homogeneous mass, was equivalent to digestion. A more recent case of a similar conveniently perforated stomach, taken advantage of by Grunewald and Schroeder, gave results diametrically opposed to Beaumont.' The Germans found raw meat and veal more rapidly digested than boiled beef! In the absence of all satisfactory experiments, we must rely much upon popular experience. It is certainly better to tell those who ask our advice upon the point, that although it may not be true, that after attaining maturity every man should be his own doctor, yet certainly every man may have discovered what agrees and what disagrees in the ordinary articles of animal food; and to stigmatise as unlawful the eating of the flesh of hogs, in a country which was never either Jewish or Mahommedan, is what may be called an infraction of Christian liberty. Pork is the cheapest animal food, and therefore the only attainable form for many, and because it does not agree with some, there is no reason to ban it with such Levitical austerity. Much depends, in this as in most things, on the form in which it is prepared, and we must take a peep into the kitchen before we dilate further upon what is digestible. On this matter we cannot do better than quote from the work of Professor Johnstone." "In cooking animal food, plain boiling, roasting, and baking, are in most general favour in our islands. 1 'Brit. and For. Med.-Chirurg. Rev.,' Jan., 1855. 2 This passage, although quoted from Johnstone, is actually derived by him from Liebig's work on the ' Juice of Flesh.' It is a pity lie should have left this fact to be stated by others. 4 50 DIET. During these operations, fresh beef and mutton, when moderately fat, lose on an average, aboutIn boiling. In baking. In roasting. 4 lbs. beef lose... 1b..... 1lb. 3 oz.... 1lb. 5 oz. 4 lbs. mutton lose... 14 oz..... 1 lb. 4 oz..... 1 lb. 6 oz. "The greater loss in baking and roasting arises chiefly from the greater quantity of water which is evaporated, and of fat which is melted out during these two methods of cooking. Two circumstances, however, to which it has not hitherto been necessary to advert, have much influence upon the successful result of these and some other modes of cooking. " If we put moist flesh into a press and squeeze it, a red liquid will flow out; this is water coloured by blood, and holding various saline and other substances in solution. Or, if after being cut very thin, or chopped very fine, the flesh be put into a limited quantity of clean water, the juices of the meat will be gradually extracted, and by subsequent pressure will be more completely removed from it than when pressure is applied to it in the natural state, and without any such mincing and steeping. The removal of these juices renders the beef or mutton nearly tasteless. " When the juice of the meat, extracted in either way, is heated nearly to boiling, it thickens, or becomes muddy, and flakes of whitish matter separate, which resemble boiled white of egg. They are, in fact, white of egg, or albumen, and they show that the juice of flesh contains a certain quantity of this substance, in the same liquid and. soluble state as it exists in the unboiled egg. Now, the presence of this albumen in the juice of DIET. 51 butchers' meat, is of much importance, in connection with the skilful preparation of it for the table. The first effect of the application of quick heat to a piece of fresh meat, is to cause the fibres to contract, to squeeze out a little of the juice, and, to a certain extent, to close up the pores, so as to prevent the escape of the remainder. The second is to coagulate the albumen contained in the juice, and thus effectually and completely to plug up the pores, and to retain within the meat the whole of the internal juice. Thereafter the -cooking goes on through the agency of the natural moisture of the flesh. Converted into vapour by the heat, a kind of steaming takes place within the piece of meat; so that, whether in the oven, or on the spit, or in the midst of boiling water, it is in reality, when skilfully done, cooked by its own steam. " A well-cooked piece of meat should be full of its own juice or natural gravy. In roasting, therefore, it should be exposed to a quick fire, that the external surface may be made to contract at once, and the albumen to coagulate before the juice has had time to escape from within. And so in boiling: when a piece of beef or mutton is plunged into boiling water, the outer part contracts, the albumen which is near the surface coagulates, and the internal juice is prevented either from escaping into the water by which it is surrounded, or from being diluted and weakened by the admission of water among it. When cut up, therefore, the meat yields much gravy, and is rich in flavour. Hence a beef-steak or a muttonchop is done quickly, and over a quick fire, that the natural juices may be retained. " On the other hand, if the meat be exposed to a slow 52 DIET. fire, its pores remain open, the juice continues to flow from within as it is dried from the surface, and the flesh pines, becomes dry, hard and unsavoury. Or if it be put into cold or tepid water, which is afterwards gradually brought to a boil, much of the albumen is extracted before it coagulates, the natural juices for the most part flow out, and the meat is served in a nearly tasteless state. Hence to prepare a good boiled meat, it should be put at once into water already brought to a boil. But to make beef-tea, mutton-broth, or other meat soups, the flesh should be put into cold water, and this afterwards very slowly warmed, and finally boiled. The advantage derived from simmering, a term not unfrequent in cookery books, depends very much upon the effects of slow boiling, as above explained." This passage contains the whole theory of the art of cooking meat. If we want to give our patients the full richness of the flesh, we must order a chop or steak, or something of that sort; if we want the flavour chiefly, and not the strength, we give beef-tea; if we want bulk rather than either flavour or strength, we can order the meat to be boiled to rags. This knowledge gives us all the command of the kitchen which we can expect to have. So much for animal food; let us now consider what the vegetable world affords in the shape of albumen, and how it is to be prepared for the table. 1st. Soluble Vegetable Albumen exists in a greater or less quantity in the juices of all plants, and in greatest abundance in the so-called grains. In its proportion of nitrogen, carbon, oxygen, and hydrogen, it is exactly the DIET. 53 same as animal albumen, but differs somewhat in the amount of Sulphur and Phosphorus. It is soluble in water and various acids. 2d. In the seeds of leguminous and corn plants, besides the vegetable albumen, is formed a substance called cleber, by Beccaria, by Leibig, vegetable fibrine. It is insoluble in water, but soluble in alkalies and acids. 3d. A modification of this is vegetable gelatine, which like kleber is insoluble in water, and soluble in alkalies and water. 4th. The last and most recently discovered albuminous ingredients in vegetables, has so close a resemblance to caseine, as to be called, by Liebig, vegetable caseine. Vegetable caseine is formed chiefly in leguminous plants. The Chinese make a cheese from peas and beans, closely resembling skimmed milk cheese.' From these chemical facts, we are able now to infer the digestibility of vegetables, as well as their nutritive property, for, as a general rule, while their power to nourish the body is in direct ratio to the total amount of their albuminous contents, the facility with which they are reduced to a state fit for assimilation depends upon the relative quantity of the soluble and insoluble form of this albumen. Besides this important explanation, chemistry also suggests the reason of dressing some vegetables with vinegar; for all forms of cabbage contain a large quantity of insoluble albumen, which is rendered One of the most distinguished chemists in this country informed me that he had prepared cheeses, la Chinois, i. e., from peas and beans, and that they were hardly to be distinguished from skimmed-milk ones. 54 DIET. soluble by the addition of this acid. It is probable that in the preparation of vegetables for the table, we have yet much to learn, and no doubt the indefatigable efforts of the vegetarians will be of use. The comparative amount of nutriment contained in the most nutritious form of animal and vegetable food, is, according to Professor Johnstone, about 3 to 1.1 c" Or a pound of beef-steak is as nutritive as three pounds of wheaten bread, in so far as the nutritive value depends upon this one ingredient," i. e. albumen. Thus we find that as Coleridge defined a rogue to be a fool with a circumbencibus, so we may consider a man who lives on vegetables alone, to be a roundabout flesh eater; for by a circuitous route he gets the same albumen as the beef-eater gets directly. Whether it is well to live solely on vegetables, or solely on animal food, or on a mixture of both, is a question to be decided by the whole circumstances of the eater. The appeal to nature made by the vegetarian propagandists, is manifestly futile; for man's nature is progress, and as one generation succeeds another, man alone of all creatures that dwell upon earth, inherits the accumulated acquisitions of those who lived before, and every child born stands in a new relation to the external world to what its parents did. Man is "the heir of all the ages," as such he accepts on his birth new duties in a new sphere of action from those who went before him. Is he to be denied the right of innovation, perpetual innovation and general progress in the food which is so essential to his life? I Op. cit., p. 128. DIET. 55 His nature is himself. He alone can resolve the problem of his duties for himself. If he finds that for their fulfilment he requires to abstain from flesh, let him abstain; but let him not insist upon putting a strait jacket upon his neighbour who is under no such necessity, and who on the other hand finds he can do his work better if he live on meat. Above all, it is lamentable that the apostles of this vegetable creed should be so carried away by their fanatical exclusiveness, as to convert the board of hospitality, where the bread, the meat, and the salt, are spread to satisfy the. various instincts of our bodily requirements, and to express the oneness of our origin, our progress, and our destiny, into a conspirator's meal, at which each guest pledges himself against the common food of his fellow-men. In former times, when men fasted, they went some days' journey into the wilderness, not to annoy their neighbours with their lugubrious faces. Might not all exclusionists in diet do well to follow this example? But we have said enough, perhaps too much, upon this head, and we must conclude with the saying of Goethe--"That is good which does us good." Newton wrote his treatise on optics living upon wine and water, biscuits and tobacco. That was good for him. We might have injured his labours if we had insisted upon his eating a mutton-chop. But it does not follow, that if we confine ourselves to biscuits and sherry, in process of time we shall be transformed into Newtons. In short, the reason of every man is, or ought to be, the absolute lawgiver upon this matter to himself, only the reason should be enlightened by the fullest knowledge of how he can best secure the ends it 56 DIET. seeks. But as these ends vary infinitely, so should the means also vary, and the whole dispute between the vegetarians and non-vegetarians is terminated by the old proverb-" One man's meat is another man's poison." Having thus briefly described the inorganic and nitrogenous ingredients of food out of which the bony skeleton with its ligaments, and the muscular fibres of the body are procured, let us proceed to investigate the character of the materials which furnish the non-nitrogenous remainder of the animal frame, and the complex series of transmutations which they undergo, before their final adjustment to the parts they play in the living organism. The starch group is the first we here encounter, and the most important. It consists of1st. StarcA or fecula. A substance found generally in those parts of a plant to which light does not penetrate. It exists in the greatest abundance in the potato, and forms above sixty per cent. of most grains. Its formula is C0 H10 010. It is soluble in warm water, and readily transformed into a substance called dextrine, of similar atomic constitution, but of different physical and chemical properties, by the contact of saliva and various organic substances. 2d. Cellulose. Of the same atomic constitution as starch, and like it, by long exposure to the action of acids, being converted into dextrine, but insoluble in water. It abounds in green vegetables, especially cabbage. 3d. Pectin. Of the same atomic constitution as the DIET. 57 former two. It is imperfectly soluble in water, but if exposed to the action of acids at a higher temperature, it passes into a substance called metapectic acid, which is soluble. Pectin is met with in large quantities in various roots, such as carrot, turnip, &c., and still more in the fleshy fruits, such as raspberries and apples. The gelatinous-looking substance so abundant in Carrhageen moss, is nothing more than a modification of Pectin. 4th. -Dextrine, or gum. These are essentially alike, but the term gum has a more limited application. Dextrine may be called the father of all the gums. It exists in large measure in all ripe fr-uits, and is the transition form of the - metamorphosis of all feculent bodies into sugar. It derives its name from its action on light; the polarized ray is thrown by it to the right; probably the ray thrown to the left, acting upon similar elements, forms true gum. 5th. Grape sugar and glucose, are closely allied, and only distinguishable by the difference of their action on polarized light, and the crystallizable character of grape sugar, which glocuse cannot attain. Besides being readily produced by the action of various substances upon other forms of fecula, it exists naturally in figs, apricots, and many other sweet fruits, as well as the grape. It is readily soluble in water, and if any nitrogenous body-be present it undergoes fermentation, as it is called, and is converted into alcohol. Sugar of milk has the same composition as grape sugar, but cannot pass spontaneously into alcohol; it requires first to be changed into grape sugar, a transformation readily effected by the action of an acid. 58 DIET. Cane sugar differs atomically from all the other sugars, its formula being C2 I 1 011; or, as there is probably one atom of water in this, the truer formula will be C12 ITI O10. Like sugar of milk, it is incapable of direct fermentation, and to acquire the useful property it has to become grape sugar, through the action of an acid. Thus we see that all the varieties of starch may be promoted into grape sugar, that highest point of advancement of the class, at which it undergoes the astonishing transformation from a sweet and harmless material for the nourishment of the body, into a fiery stimulant called alcohol, the most fertile source of every human crime, the great parent of madness and suicide. The second non-nitrogenous group consists of substances from which fat is derived; for although grape sugar may be converted into fat, yet this transformation is made more easily if ready made fat be present, and it exists in large quantities in various forms of food. The most widely distributed form of fat is elain, which constitutes nearly eighty per cent. of olive oil. Its formula is calculated at C35 HSS O4. It is generally met with as an elaic acid, and as such, or as a soap, is received into the blood. Next in abundance to elain is margarin, which constitutes sixty-eight per cent. of butter, and enters largely into the composition of all solid fats. Its formula is C35 H"6 O4. Stearine is much more rarely met with; it is found in mutton suet and cocoa. Its formula is C37 H37 O". The last member of this group which is of any importance in a dietetic point of view, is Butyrine, which is DIET. 59 a constant constituent of milk, although it is in the small proportion of two per cent. It is readily decomposed. Its formula is Cn H" O1. The above group, as will be perceived, abounds in carbon, and yet the demand for this element is so large, both for the purposes of respiration, and to form the many carbonates that exist in the body, that besides the contributions derived from the various forms of fat, a considerable amount is afforded by various acids, which constitute the third and last non-nitrogenous group. The most important of these are the oxalic, malic, citric, tartaric, acetic, and lactic. All these acids are very similar in atomic constitution, consisting generally of four atoms of carbon, two of hydrogen, and from three to five of oxygen. The formula of lactic acid deserves more specific attention, for it is readily formed from grape sugar, it stands thus: C6 H O1. As this acid is found, in combination with alkalies, in the muscles, it is probable that it passes unchanged into the blood. As also the acetic, for it is met with in the perspiration, although in small quantities, and, no doubt, much the largest quantity of the acetic acid we use, is changed into carbonic acid and water. All the acids we have enumerated are readily decomposed, and form new combinations with the various complex bodies they encounter in the blood. It would be out of place here, to attempt to follow their chemical progress, and we shall now proceed to the more interesting task, of describing the process by which the most important members of the non-nitrogenous groups are adapted for the various offices they have to fulfil in the state corporeal. 60 DIET. Let us first pursue the history of starch, which enters so largely into most vegetable diet, from its entrance into the mouth, to the transformed existence it presents in the blood. When food is taken into the mouth, there is, or ought to be, an immediate flow of saliva from the various glands connected with that cavity. The action of this saliva upon starch is very remarkable, as it gradually converts it first into dextrine, and then into sugar. Digestion then begins in the mouth, and from this important fact, too much lost sight of, we may deduce several dietetic rules. The first that occurs is an old adage, that food "w well chatted is half digested:" a curious example of the popular instinct anticipating the scientific discovery; for it is literally true; the chatting during a meal prolongs the process of mastication, and has also the effect of conveying the requisite amount of nervous influence to the salivary glands. No part of the system is more under the influence of the emotions than these organs. "The mouth waters for dainties," is a literal fact. The sight and smell of food make the mouth weep in pleasurable anticipation of the " sweet morsel" it will soon "roll under its tongue." How exact is this description! While gaiety thus improves what we may call the oral digestion, fear and anxiety exercise as powerful an effect in the opposite direction. The dryness of the mouth is a symptom of terror, suggesting the expression, "vox faucibus haeret," or, " the tongue cleaves to the roof of the mouth." In India a thief is detected by desiring him to chew rice in his master's presence; the saliva will not flow from fear, for " conscience doth make cowards of us all," and the thief is unable to make any impression upon DIIET. 61 the dry hard grain. So much for the importance of recommending social meals, and the obvious risk of throwing an undue amount of labour upon the stomach by bolting food. Is it not possible, that this habit, which is said to be so common in America, is one of the causes of the remarkable leanness of the people? For, as we shall see afterwards, the ultimate destination of this starch and sugar is to supply fat to the frame. Another question of great practical importance here suggests itself, viz.-whether we do wisely in restraining our patients from all spices. The action of mustard and pepper, and of seasoning generally, is very powerful upon the salivary glands; and it is a remarkable fact, that while the taste for sweet things is the characteristic of childhood and boyhood, the love of tarts and sugar-plums, as a rule, entirely gives place to a relish for spices in maturer years. If we condemn our patients to eat tasteless farinaceous food, shall we not incur the risk of subjecting them to the punishment of the thieving Hindoo, and will they not be too glad to get rid of the insipid stuff as expeditiously as possible, that is, little digested in the mouth, and gulp it down, c" unhouseled, unannointed, unannealed," to the sepulchre of their stomach, where it can hardly expect a proper welcome, coming in so unmannerly a fashion. If this is in any measure true of mature manhood, it will be much more so of advancing years, when the apparatus for disintegrating food, so that it may be well kneaded with saliva, is all broken and useless, and at the same time the sense of enjoyment is diminished, and there is less lively participation of the cerebral functions in those of nutrition. To insist upon an old man eating his beef and bread 62 DIET. without mustard, is almost as cruel as to give him mustard without bread or beef. The mustard, -to him at least, is an essential; without it he could not instigate the glands of' his mouth to pour out their contribution to the first act of digestion. The starch, then, on its arrival at the stomach, has already undergone a partial transformation into sugar, the process is there completed by the action of the pancreatic, fluid, which bears a close resemblance to saliva, and by the secretions of the stomach itself, the most important of which is the complex substance called pep~in, whose characteristic peculiarity is, its power of inducing active molecular changes in all organic matters susceptible of its influence. It is, in short, the digestive principle in its purest form. Besides converting the unreduced remnant into sugar, it acts upon the sugar in such a way as to transform a portion of it into lactic acid. This is also done by the bile, but the full action of the bile upon the chyme is yet unknown, and how sugar is converted into fat is still an unsolved problem-possibly an insoluble one, for it is the step out of chemistry into vitality. This first act of vital generation, by which the -hard and angular chemical sugar is transformed into the soft and globular vital oil, wherewith the lamp of life is fed' at the lungs, and the whole bodily machine kept pliant and warm, seems to be in some way or other under the direct control of the brain. The nervous system, the differential between what is vital and what is chemical, here asserts its claim for the first time over the contribution to the reconstruction of the living body presented by external nature. This important fact has come to light during thle investigations into the cause of the curious disease DIET. 63 known by the name of diabetes mellitus, which seems to result from the incapacity of the brain to discharge its requisite office, and transform the sugar, presented to the organs of assimilation, into fat, so that, as sugar it enters the blood, and as sugar leaves the body by variouis emunctories, and thus the body is starved of its fat, and extreme emaciation, going on generally to death, is the consequence.' No doubt a portion of sugar, and a large portion, may continue unchanged in the blood, till it passes through the lungs, where it may be oxydized and converted into carbonic acid and water; but there is as little doubt, that what we consume as sugar is largely converted into fat; and hence the fattening effect of a purely sugar diet upon the negroes who work at the sugar-cane plantations. The facts which seem to me of such immense importance to us practically, are these two, that we are now on the road to discover what substances yield the elements of fat to the body, and what the condition of the body is which enables it to turn its opportunities to account; and what the bodily states are, on the other hand, which debar it from the privilege of converting the bounties of nature into that ductile element, which rounds the harsh masculine features of bone and muscle into feminine beauty, and tends to mollify the temper and tranquillise the mind. Besides the fat we obtain from the starch and sugar we consume, there is a considerable quantity of it in the principal grains employed in making the various kinds of bread, or the cakes and other forms in which 1 This subject forms the matter of the next Chapter, "On the Structure and Uses of the Liver." 64 DIET. meal is prepared for use. And it is of consequence to know the proportion in which it exists in the different varieties of these bread-stuffs, for upon the amount of fat seems to depend the laxative or binding action of these articles of diet upon the alimentary canal. Professor Johnstone, in the book we have before so often alluded to, gives the following proportions: In fine English wheaten flour.. 2 per Cent. In bran of English wheat.. 6, In Scotch oatmeal... 6 In Indian corn..... 8 From this table we learn that fine wheaten bread contains only one third the quantity of oil contained in oatcake or bread made from bran, and that we may derive a useful hint fr-om this in the management of cases attended with constipation. It was generally supposed, that the bran acted as a foreign body upon the mucous membrane, and that from the irritation it produced, the peristaltic action was increased. This may be partly true, but the presence of the oil is undoubtedly highly conducive to the greater activity of the bowels. Rice contains very little fat, and hence its binding tendency upon the bowels. Indian corn, on the other hand, is, very rich in fat, and might probably be more extensively used in this country, with great advantage. All travellers in America dwell with much gusto on the delicious cakes of Indian corn that are there served up at breakfast. Although we derive the elements of the fat, which enters into the composition of every tissue of the body except the enamel of the teeth, and constitutes the bulk DIET. 65 of the brain and nerves from various forms of fat that present themselves both in the animal and the vegetable kingdom, yet the modifications these endure before they take their new place in our frame, is much greater than any which the other primary constituents undergo. In the brain it is found in the form of two acids, the one called cerebric, the other oleophosphoric; the latter possesses the interesting property of being resolved by heat and water into Elaine and phosphoric acid. This fact maythrowa light upon the important observations recently made by Dr. Bence Jones, upon the amount of phosphates in the urine being the measure of the waste of the nervous system. It does seem strange that with such facts as this one and many others staring us in the face, to show the immense value of fat as a source of nourishment to all parts of the body, and chiefly to the most noble parts of allthe brain, it should be the fashion of chemical physiologists to speak of fat as if it served no other. purpose than to be burned at the lungs to warm the rest of the body. Surely, the curious fact of hibernation alone might teach us that fat went far to sustain life, for from the store accumulated in themselves during summer and autumn, must the beasts and other animals which pass the winter in sleep, without food, draw the whole nourishment during the months of their retirement from active life. To deny the name of nourishment to that which sustains the life of an animal, involves a paradox; and in this instance the paradox results from an exclusive application of the term nourishment to substances which supply the materials for constructing the fleshy parts of our tabernacle, 5 66 DIET. and ignoring the existence of the earth and fat, which are essential to the formation of the organs of sensation and locomotion. The sophism implied in this paradox lies at the root of the entire misrepresentation of the effects of alcohol, by those who deny to it any nutritive qualities; and as the subject is one of unsurpassed importance and interest to us as physicians, it will be right to inquire fully into the properties of alcoholic drinks, regarded, not as medicinal stimulants, but as articles of strictly dietetic or nutritious use. The ground we are now entering on, demands from us a most dispassionate investigation, for it is beset with difficulties on all sides, and requires that we should at the outset clearly define what are our special duties in this matter, as contradistinguished from those who are most prominent in leading public opinion upon it. To those who devote themselves to the arrest or mitigation of the frightful evils produced by intoxication, whether by popular lectures, or by addresses from the pulpit, or by the organization of societies, we wish to express the deep sense of our obligations, for their noble and patriotic efforts, and in so far as it is in our power to advance the great cause of temperance, in our capacity of citizens, it is surely our bounden duty to do so. But the restraint of excess is a wholly different question from the proper use of any article of food; and if out of dread of offering an obstruction to the promoters of a great philanthropic movement, we shirk a candid investigation of the alleged benefits to be derived from a temperate indulgence in all the drinks they find it expedient to condemn, we should be abdicating our position as ad DIET. 67 visers of those who consult us as to what is best for them, and be betraying their interest and our duty for the promotion of a remote and hypothetical good. We have no right to sacrifice our patients upon the altar of temperance. There is no more inconsistence in promoting the cause of temperance, and recommending the use of wine, than in doing all we can to advance a Fire-Insurance office, with all its machinery for extinguishing a conflagration, and each of us at the same time making these very efforts by the comfortable warmth of his " ain fire side." Temperance is the law of life; the torrid and the frigid zones are equally inimical to man, nor less so pro. bably would be found the universal abstinence from wine and all its kindred. Nay, we do not take up a merely negative position in reference to temperance, while thus claiming a fair hearing for what its soi disant advocates condemn, we go further, and maintain, that if it be shown that the use of wine, spirits, and beer, be conducive to health in certain circumstances, by recommending their use, we are really doing more for the ultimate triumph of temperance, than by passing no end of Maine-liquor laws; for it is a fact beyond all denial, that one of the most fertile causes of intemperate indulgence is traceable to some bodily infirmity or depravity, and that intoxication is hardly possible for those whose bodily and mental conditions are in the highest state of vigour and refinement. I have been thus free in the expression of my sentiments, because I find myself opposed to the views of many, whose opinions deserve the highest attention and consideration at our hands, and with none more than Dr. H. Madden, who, in an article published in 1846, in the 68 DIET. 'British Journal of Homceopathy,' makes the following observation. " Alcohol when acting not as a stimulus, but substantially, is not and cannot be a pabulum to any organ, and for the following reasons:--first, its chemical composition disqualifies it from taking any share in the formation of muscular fibre, or other azotized compound, since it possesses no azote; and it has now been proved that the higher orders of animals have no power to compound their proximate principles, but must obtain them ready formed: second, although its chemical con. stitution has some approximative relationship to nervous matter, we have no proof that it is or can be transformed into that substance, while numerous arguments may be drawn from transcendental chemistry, to show its extreme improbability." In opposition to this statement, we think we shall be able to show that alcohol may supply a pabulum to every organ by affording it the materials whence to derive its fat, which is essential to its healthy action, and also that there is every probability of its nourishing as well as cherishing the nervous system. Human fat, according to Chevreul, contains 79 per cent. of carbon, while alcohol contains 53 per cent. of the same element, and the conversion of alcohol into fat is farther rendered probable by the examination of the blood of persons who have imbibed alcohol in large quantities: their blood has been observed to be of a whitish, milky appearance, from the quantity of fat globules that float there.- There is a case on record in which all the organs of the chest and abdomen, and even the muscles in the body of a drunkard, 1 Wilson on the 'Pathology of Drunkenness.' DIET. 69 were found conveited in a great measure into a fatty substance.1 So much for the first proposition, that alcohol goes to make fat in the body: a statement which, although we cannot assume as a fact, we may assert as a very probable conjecture. As to the second, that alcohol by loading the blood with fat, probably affords special nourishment to the nervous system, which consists in a great measure of this substance, it seems also probable, not only from the fact of the chemical composition of the two, but from its physiological action as a narcotic. We know, indeed, as a positive fact, that the brain is nourished during sleep, and we also know that, as a general rule, the tendency to sleep is in direct proportion to the quantity of fat in the body. Fatness and somnolence are mutual cause and effect, as we see in the example before referred to, of hibernating animals who do not go to sleep till they have laid in a great store of fat, and who then pass their whole time in this condition, and the converse we see in the effects of sleeplessness producing all the evils of insufficient nutrition on the brain. " All the causes," says Dr. Bucknell, in a recent article in the "British and Foreign Medico-Chirurgical Review,' " even of the acute forms of insanity, point to an interference with the due nutrition of the brain. Starvation causes raving delirium, mortification produces muttering delirium. * * ~ If anything is positively known of the brain and its functions, it is that it expends its powers during the waking state; and that it is nourished and its powers are recruited by cell-growth, or otherwise, during sleep, * * * and during the prodromic period of 1 Rosch 'Der Misbrauch geistiger Getriinke,' p. 93. 70 DIET. threatened insanity, opiates often act like a charm." 1 That -alcohol does act narcotically, especially if combined with another narcotic, such as that of hop, requires no proof: it is an admitted fact. And now we are in a position to perceive how it is that the English and the Germans are a fat race, while the French and the Scotch are lean. The former drink beer, which contains about the same amount of alcohol as the light French wines, but in combination with a narcotic and nutritive extract to the extent of from 4 to 8 per cent; while in milk, the model food, the nutritive matter is about 12 per cent. So that a pint and a half of good beer is equal, in respect of solid nourishment alone, to a pint of milk. But it has this immense advantage over milk, that it soothes the over-active nervous system at the very instant that it presents to it its means of nourishment. It. cherishes and nourishes at once. Shall we then, misled by the crude speculations of modern chemists, reject the evidence of all history in favour of the mighty boon conferred by Bacchus on our race? When we reflect that in the present age the work is done more with the brain and the nerves, than with the muscles and the bones, that we have now bones of iron and muscles of steam, which relieve to a great extent those of the human frame, and that this substitution is daily progressing; while, on the other hand, the strain upon the mental and cerebral system is proportionally increased, for we cannot multiply brains by any process of machinery yet invented, and that this very liberation from the toil of the hands begets greater and greater competition in the race ' Brit. and Foreign Med.-Chirurg. Rev.,' Jan., 1855. DIET. 71 of mental achievement; when we reflect on all this, is there not something very presumptuous in venturing against the most advanced investigations of physiology, to enforce more than monastic ascetism upon those who instead of the dawdling life of the monastery, with the trifling expenditure of its hibernating existence, have daily to undergo a waste of cerebral and nervous matter in the furnace of a city, to an amount hitherto unknown in the annals of our race? If we forbid alcohol in all its forms, is there not a danger of oiu' starving the brains and the nerves? May not a portion of this substance be absolutely necessary for those who like pleaders have to go through a work of intense cerebration, so to speak, for hours together? Certainly in my own practice I have met with many instances where the health was kept in a. state of deterioration by abstaining from alcoholic drink,. and where the addition of a glass of ale or a glass of wine permanently improved the health and comfort of the persons; and I believe, notwithstanding all the averments of the teetotallers, will contribute to the prolongation of a life it has already made happier. There is wisdom in the adage that wine is the old man's milk. Before considering the comparative value of different forms of alcoholic drinks, let me observe that the cases in which marked benefit was derived from their administration as articles of regular diet, not occasional stimulants, were all characterised by the feebleness of the pulse, and a difficulty of obtaining a sufficient quantity of sleep. This entirely corresponds with what our physiological investigations might have led us to expect. In such instances, alcohol in its proper form at once propitiated the appetite of the nervous system, and presented 72 DIET. to it its most appropriate aliment. At the same time it is right to state, that the greatest caution is required in deciding on the class of cases which are suitable for this method of treatment, for it certainly is extremely injurious in many cases characterised by a feeble pulse, if there is preternatural general irritability present. In such cases it acts not as a sedative, but as a stimulant, and increases instead of mitigating the evil. I have known immediate improvement to follow the withdrawal of all stimulants, in cases where the heart is at once feeble and irritable. Indeed I do not believe there is any matter connected with the management of those who consult us that requires so much care, and about which, with all our caution, we shall so often commit errors in giving a reply to the question: what must I drink? Perhaps it may be well to give Dr. Bence Jones's resume of the various qualities of alcoholic drinks, as it may afford us some guide in the solution of this intricate and perplexing problem.' " Generally then, it may be said, that beer contains much saline matter, wines contain very little, and spirits contain none at all. Each year our knowledge of the chemical composition of these fluids will increase, and with advancing knowledge we shall obtain more clearness regarding the dietetic and medicinal properties of all fermented liquids. At present, the answer to the question which is the best wine, cannot be given, because of the imperfect knowledge which we possess of the chemical composition of different wines. But even when full knowledge is obtained, no universal answer can be given; for that wine which is best in one state, or for one person, may be the worst in a different state, S' Medical Times and Gazette,' for Sept., 1854. DIET. 73 or for another person. Generally, however, it may be said, that that wine is best which contains least alcohol, least acid, least sugar, and highest flavour. This is the best for a person in health, while for a person in a state of low fever, that wine which contains least salts, most sugar, most astringent acid, and most alcohol, will cause least irritation of the bowels, will furnish most nutriment, be most febrifuge, and most supporting. Where there is much irritation and much depression, brandy will be better than wine. In some states in which diuretic action is desirable, Moselle wine, by the excess of salts it contains, may prove almost as energetic and far less heating than the essential oil in gin or whiskey. The difference in action being that between cream of tartar and oil of turpentine. In diabetes, ale and porter, which contain much sugar, cannot on rational gromunds be advised, while claret, which is free fromi sugar, and contains perhaps much tannic acid, is highly beneficial. While cider, though free from sugar, contains much malic acid, and is diuretic. In dyspepsia and gout, the wine which is freest from ultimate acidity, and which is least stimulating, is best. The least acid claret wines, first, and then some sherry, and even perfectly dry champagne, when very free from excess of acid, are not unsuitable. When a taste is acquired for good Mansanilla, it answers all the requirements, and is obtained at a far cheaper rate than fir'st rate Amontillado sherry, which may be procured free from all sugar, and with little acid, and scarcely stronger than Mansanilla, and so far surpasses it in flavour, that the difference in expense is almost forgotten. But by adding water to brandy, or other spirit, a fluid is obtained which is far less acid than any wine, 74 DIET. and which may be made of any strength, and be free from all sugar. Theory, then, as well as practice, leads to the belief that if any stimulant is taken in dyspepsia, the best is brandy and water. With regard to porter and stout, these containing little acid, have much sugar, and hence give rise to much more acidity than some pale ale. [But at the same time are pro tanto more fattening if they agree.] Some pale ale may be found more sweet and acid than ordinary sherry, but generally pale ale is more acid than sherry, and less stimulating. Yet for this, compensation is made in the greater quantity of ale drank. The larger quantity of salts also in malt liquors must always be borne in mind. Such is the meagre information which at present is the best I can bring before you to enable you to answer the question: what may I drink?" The question of how much, must also receive answers as various as are the habits and capacities of those who ask it. One man's extremest idea of temperance conveying to another the horror of a debauch. I recollect a celebrated writer, who is now far advanced in years, remarking to me in reply to my question of whether he took much wine, "I drink very little now," he said in the quietest tone, "I seldom take more than eight or perhaps ten glasses of sherry at dinner." A limit of indulgence which would have entitled him to be enrolled on the books of a temperance society instituted towards the close of the 14th century by the Landgrave of Hesse, the rules of which restricted its members to seven bumpers of wine along with each meal, which at three meals a day, and allowing six bumpers to a quart, would give each man more than three daily bottles. DIET. 75 We should have here considered the effects of the other sources of fat, and especially of cod-liver oil, but that the subject has been ably handled by so many writers, as to make it a work of supererogation. There is one observation, however, it may be right to make, in order to prevent disappointment from the results of this fashionable remedy, and it is this: In cases of phthisis it may fatten the patient to such a degree as to give a delusive appearance of restored health, while all the time the mortal malady is making rapid progress to its inevitable end. As to the value of inunction, a still more fashionable mode of introducing fat into the body, I confess myself to be very dubious, from the few trials I have made of it. I have found, in several instances, unspiced turtle soup one of the most digestible forms of presenting fat to patients in a state of extreme emaciation. Of the dietetic value of cocoa, in this point of view, I shall speak presently, when considering its claims as a beverage, along with those of tea and coffee. Before doing so, it may be right to state, that howeven important fat is to the economy, yet both oil and sugar are so readily decomposed and converted into a variety of acids, some of which are of a highly indigestible character, that, practically, they are usually found unsafe articles of diet, unless presented in circumstances well adapted to secure their admission without decomposition. Sugar is safest in the form of grape sugar, and it is owing to this that the grape-cure owes its efficiency probaebly, in cases to which it is suited. It is said to be specific in certain forms of diarrhoea or dysentery, but I am not aware of any trustworthy details of the way in 76 DIET. which it is used. Milk thickened with mutton suet, has an excellent effect upon children who are weak and lean from long-continued diarrhoea. And broiled bacon is found by many to be a useful substitute for butter at breakfast. No doubt in this, as in other forms of aliment, individual peculiarities of taste and disposition, impossible to specify by anticipation, must be taken into account. The importance of coffee, tea, and cocoa, as articles of diet, requires no enforcement. Of coffee alone, the consumption in the United Kingdom, amounted, in 1853, to thirty-seven millions of pounds; and yet coffee is of comparatively recent introduction into Europe. According to Abd Alkader Ebn-Mohammed, who wrote a treatise in 1566, entitled, ' The Prop of Innocence, in Reference to the Lawfulness of Coffee,' a very learned and pious sheikh became acquainted with this beverage in Abyssinia, and introduced it into Aden about the beginning of the fifteenth century, under the name of kahwa. In the year 1554, an alarming tumult arose in Constantinople, no less than an emeute of the priests against the sultan, because the opening of coffeehouses had been attended with such irresistible attractions to the true believers, that they had all deserted the mosques. With the sagacity of one born to rule, the sultan settled the matter by heavily taxing the coffeehouses, thus relegating to the mosques the poorer portion of those who frequented them, satisfying the priesthood, and enriching himself. In 1652, a Greek, of the name of Pasqua, opened the first London coffee-house, in George Yard, Lombard Street; and in 1671, the first / I! DIET. 77 was opened in France, at Marseilles; it was niot till 1721 the first coffee-house was opened in Berlin. Thus began the second Byzantine empire, which is likely to be more enduring and fruitful of great political results than the first. For it is hardly too much to say, that if there had been no caf6s in Paris, there would have been no French revolution, or, at all events, its history would have been very different. The most important chemical ingredients of roasted coffee are: 1st, a volatile oil produced during roasting; 2d, a variety of tannic acid, modified by this process; and 3d, a substance, called caffeine, similar to the thcine and theobromine of tea and cocoa. The physiological effects of the infusion or decoction of coffee are very peculiar. It seems to act especially upon the spinal and respiratory system of nerves, rather than on the cerebral, as alcohol does. It is well worthy of consideration, that while wine induces sleep, coffee and tea prevent it. And it may be, that the increasing number of spinal affections, which are undoubtedly met with now, are, in some measure, due to the much larger quantities of tea and coffee consumed. It has, besides, a most remarkable effect in retarding the waste of the tissues, and thus, is indirectly nutritious; it husbands the strength of the person who drinks it, and so increases his wealth: as a man's riches depend upon the excess of his revenue over his expenditure, and what diminishes the latter, augments the former. Some interesting experiments have been made upon this subject, and the result was to prove, in the instances recorded, that by the use of one and a half ounce of coffee daily, the absolute quantity of urea and phosphoric acid voided 78 DIET. from the system in a day was diminished one third, while the absolute quantity of urine was increased by a fifth. If this experiment be confirmed, it shows that coffee, to some extent, gives us the control of the waste of our bodies, and when we recollect that life is an incessant stream, the rapidity of which, in a great measure, determines the amount of health and strength; that the rapid exhaustion of fever is the acceleration of the river of life in the body, and, that the arrest of decay implies increased energy and prolonged vigour, there is no wonder that those who are exposed to great wear and tear of the body, especially of the nervous-ingredients of it, should cling with desperate tenacity to those beverages, which experience, now ratified by scientific observation, tells them, tends to reduce to a minimum the expenditure of substance during the efforts they are obliged to make. And, while to deprive a man of his wine may be to starve his brain and his nerves, by withholding from them their requisite sources of food, to deprive a man of his tea and coffee, may operate with equally disastrous consequences, by involving him in an expenditure to which his means are inadequate. The quantity of tea consumed in the United Kingdom in 1853, amounted to fifty-eight millions of pounds, while in Germany, with a population of four millions more than the British, it was only one million and a half, and in France only half a million. This accounts for the ghastly parody of the refreshing beverage with which the traveller in these countries is generally mocked, and displays the absurdity of homceopathists transferring Hahnemann's inhibition against coffee to this country, while tea, which takes the same DIET. 79 place here held by coffee there, is allowed to be used with certain faint admonitions against its excess. For the physiological effects of the two are very similar, depending, in a great measure, upon the presence of the peculiar highly nitrogenous principle, called theine or caffeine. The difference between black and green tea depends entirely, according to Mr. Fortune, our great authority in this matter, upon the mode of preparation. Green tea is dried rapidly, while the leaves are fresh; while black tea is exposed for some time to heat and air, which induce various unknown chemical changes in their substance, and mitigate its sleep-destroying properties. It is usual in China to prepare the green tea for the foreign market with a small quantity of copper to intensify its colour, and to the deleterious action of this substance, some of the evils of green tea are ascribed. However, recent investigations have proved, that the amount of copper employed is so minute, as hardly to be of any consequence -at least, so it is maintained. All that has been said of the action of coffee upon the nervous system, is equally applicable to tea, and does not require to be re-stated. I believe its moderate use to be perfectly harmless, and that it in no way interferes with the action of homoeopathic medicines. The quantity of cocoa consumed in this country, although still greatly inferior to that of tea or coffee, is rapidly on the increase, being no less, in 1853, than 4,126,000 pounds, while in 18332, it was only 1,150,000. Like tea and coffee, it contains a peculiar highly azotized principle, called theobromine; the composition of this is, N4 C14 H8 04; while that of theine is N2 C8 H5 02. And 80 DIET. if cocoa were prepared and used in the same way as coffee, it is probable the effects would be much the same. This, however, is not the case; it is not roasted and infused, and the infusion drank, but boiled, and eaten in substance; and besides various ingredients in common with tea and coffee, it has a much larger proportion of oil, amounting to between fifty and sixty per cent. while in coffee there is only ten per cent. and in tea none at all. It is to this difference the fattening properties of cocoa are due, and this too is the reason why it is found to be indigestible by many. In Spain, and other countries where it is much used, it is not the practice to use bread and butter with it, but generally a species of rusk or roll of biscuit. In a chemical point of view, there is not much difference between a breakfast consisting of tea and bread and butter and one of cocoa, and the attribute homoeopathic, applied to the latter, seems to be somewhat arbitrary, if not clap-trap. The so-called homceopathic cocoas are no way different from the other cocoas, except in being mixed with various proportions of sugar and arrowroot, or potato-flour, which lessens the proportions of oil, and improves their flavour to most palates, and their digestibility to most stomachs. On this admixture Dr. Hassall has made some very severe strictures, denouncing it as a fraudulent adulteration, on the ground that the only design the chemists who prepare the cocoa can have in view, is to increase their gains, by selling a cheaply prepared article at a high price. With his condemnation of those - and I am sorry to say they are a considerable number - who adulterate their cocoas with earths, it is impossible not to concur in the fullest extent, but I do not see that those DIET. 81 who prepare a wholesome and nutritious article of food, the basis of which is cocoa, are to be blamed for selling it under the name of homoeopathic, or dietetic, or any other title they fancy; as to the price, that is their affair and the public's. The whole idea of trade is gain. To buy in the cheapest market, and sell in the dearest, is the fundamental principle of commerce. Shall we blame tradesmen for obtaining the highest price for their wares? Shall we not rather say, if the price be too great, let it be brought down by competition. There is no monopoly except that obtained by superior skill, capital, and reputation. MILK. We have still a few words to say about milk. This is called the model food, because it contains in nice proportions, albumen, gelatine, and fat. In a dietetic point of view, the chief point of interest is, to determine the kind of milk best suited to various purposes. The modification of milk called colostrum, on which the first days of the infant's life are sustained, differs from the after-milk, in containing a considerably larger quantity of all the solid parts. Thus, at birth, the caseine amounts to 40 parts in 1000, while at the end of the fourth day, it is only 35 or 36 parts, the sugar is as high as 70 instead of 41, and the butter 50 instead of 35. This is an important fact to bear in mind, when we are required to supply an artificial substitute for the natural aliment of a new-born infant. In the course of lactation, there is a gradual tendency to an increase of caseine, and a diminution of sugar and butter; at the fourth month, the 6 82 DIET. relative quantities of these ingredients, as compared to the first fortnight, are, caseine 40 instead of 22; sugar 45, instead of 56; and butter 23, instead of 27. There is also a marked difference in the quality of the milk of fair and dark women. This observation, which is a popular notion, has been scientifically corroborated by 'Heretier, who subjected the milk of fair and dark nurses, of the same age, to chemical analysis, and found, that while in the fair the amount of solids varied from 108 to 118 parts in 1000, in the dark nurse's milk they amounted to 146 and 147 parts in 1000. The milk of the cow is nearer in chemical constitution than that of any other animal, to the human milk. By the addition of one third part of water and some milk-sugar, the resemblance is made nearly as perfect as we can expect. The milk of the ass contains much less butter than that of the cow, and for this reason it is preferred for many delicate persons. The effects of disease upon the secretion of milk have not been much investigated, but Labillardiere has made the very important observation, that the phosphate of -lime is increased no less than seven-fold, in the milk of cows suffering from a tuberculous affection of the lungs. This fact should put us on our guard, when we give an opinion as to the propriety of a mother suckling her child, and we must not allow ourselves to be induced, by the laudable efforts which are now fashionable, in favour of the mother being nurse to her own offspring, to endanger the future constitution of the infant, by supplying it with improper food at an age when growth is so much more rapid than at any future period of its life, and when, consequently, any imperfection in the DIETr. 83 elements on which it lives, is most likely to be attended with important results. The publication of this paper in the 'British Journal of Homeopathy,' in the year 1855, excited much interest among the adherents of the homeopathic system in Germany. The greater part of it appeared in the "cAllgemeine Hom. Zeitung.,' and thle accomplished editor of the 'Horn. Vierteljahrschrift,' Dr. M. Miller, wrote an able and liberal article upon it in his valuable quarterly journal. His article in its turn became the exciting cause of various others all more or less learned and ingenious. It would be out of the question here to do more than refer to these numerous articles, as a proof that the question was ripe for discussion, and I take this opportunity of acknowledging my obligations to the critics who have written about my imperfect little treatise, for the kindness and candour 'with which they have expressed their opinions when they differed, and the cordiality with which they agreed. CHAPTER 111. ON THE STRUCTURE AND) USES OF THE LIVEiR. IN the annals of the liver we might read the history of science and the progress of human thought. It was probably first attentively scrutinised by the Augurs, the most primitive anatomists, and from its colour and shape political predictions were drawn, and inspiration given to the i1ionitezers and Times of those days: and "CcWhen science from creation's face Enchantment's veil withdrew," so far from the " glorious visions" yielding " their place to cold material laws," it was found that the more the matter was examined the greater grew the interest, and that one discovery only made way for another; so that although during the last two hundred years about one hundred and fifty treatises have been written, many of them by the greatest men of their age-such as Malpighi, Hoffman, Haller-upon the structure and functions of this organ, yet it was reserved for a manl of our own time to announce a series of discoveries about the uses of the liver, of so new and startling a character as to attract the attention of the world at large, and which, if confirmed, wviii place the name of Bernard beside that of Hailer. Interesting, in a general way, as these discoveries are to all, they must have a special interest for us whose high prerogative it is to convert all that is true STR'UCTURE AND USES OF THE LIVER. 85 in the science of medicine into something fruitful in the great art of healing. The liver is the largest gland in the body, even in adult life, although then very much smaller, proportionally, than in the foetal condition; in the human species it is one third of the weight of the whole foetus at the end of the first month, and one eighteenth at the end of the ninth month.1 Its average weight in a healthy man is from three to four pounds; it measures about twelve inches in length, and six to seven inches in depth; its bulk corresponds to nearly one hundred cubic inches. This great mass is made up of a multitude of lobules, and the variation in its dimensions in different classes of animals depends much more upon the number of lobules than upon their size. Between the lobule of the liver of a mouse and of an elephant there is but a comparatively trifling difference, the enormous magnitude of the latter depends upon the enormous multitude of -lobules. In some animals, as the pig, these lobules are distinct, but generally they are only discoverable by dissection. Each lobule may be looked upon as a little liver, and the anatomy of one is the anatomy of the whole. The fundamental requirements in a lobule are three-fold: 1st, Vessels to bring blood to it; 2d, Cells to operate upon that blood; and 3d, Vessels to carry away what has been analysed by the cells. The analysis consists in the separation of bile, which flows off by the biliary ducts, and the formation of sugar, which passes into the venous blood and is carried on to the heart and lungs. The first set of vessels, or those which supply the liver, are the hepatic artery and the portal vein. The 1 Burdach, vol. iii, p. 483. 86 STRUCTURE AND USES hepatic artery, a branch of the abdominal aorta, is the feeder of the liver; as such, it is distributed upon the coats of the ducts and capsule: after discharging its functions there its contents are collected by venous radicles and discharged into branches of the portal vein. The portal vein is formed by a union of all the veins of the intestines, except those of the kidneys and bladder. It comes direct from the seat of digestion, and contains Fig. a. LOBULE OF THE LIVER, OF A PIG. This represents tihe branches of the portal vein in the liver of a pig forming an imperfect circle round the centre of the lobule where the hepatic vein lies, but which is not represented in this plate. the blood in its rawest condition. Its distribution in the liver is very peculiar, and unlike that of any other vein in the body. The ordinary office of veins is to collect the blood, not to distribute it, and in their course the branches naturally diminish in number and increase OF THE LIVER. 87 in size; but the branches of the portal vein' ramify like an artery, and encircle the lobules-as represented in this woodcut. The cells of the liver are the seat of the vital force which operates incessantly upon the blood, inducing in it, in a wholly mysterious manner, those molecular changes which it is the appointed office of the organ to effect in the general economy of the body. These cells are very minute, varying from 1-800th to 1-2000th of an inch in diameter.1 Each cell contains a nucleolus of a circular or oval form, and about 1-3000th of an inch in average diameter. Besides these nucleoli the cells contain oilglobules and granules of yellow coloring matter, and are remarkable, as compared with other gland-cells, for the variety in their form and size, and their high refractive power. It has been, and still is, a disputed point, whe. ther these little cells lie simply imbedded among the capillary vessels, or enjoy a private dwelling-place in what is called a basement membrane. Dr. Beale is decidedly in favour of the latter opinion, and represents the cells as occupying a tubular network radiating from the centre towards the circumference of the lobule like a spider's web. In the foetus the distinction between the capillary and the tubular network is manifest, but the partition walls being of the most delicate material, what was originally an interlacement of tubes, tends to become a common cavity, and it is very difficult to demonstrate this arrangement in the liver of the man. Whether such a net of fine tubes containing these secreting cells exists or not is not apparently a question of any great importS Dr. Handfeld Jones, ' Philos. Trans.,' 1846-49-53, and 'Med. Chirurg. Trans.,' 1852. 88 STRUCTURE AND USES ance, except to the anatomist. It is enough for the physiologist that a mechanism exists by which the blood of the portal vein, loaded with the drainage of the stomach and bowels, should be exposed to the action of these resolving cells by which its division into blood and bile is effeeted. How it happens that the bile should percolate the walls of the capillaries and the blood flow onward, belongs to the elective affinities of the organism, which must be recognised as an ultimate fact, at which we may wonder, but which we can never comprehend. We have now arrived at the centre of the liver, to which the blood has been conveyed by the ramifications of the portal vein, to be exposed to the influence of the cells and decomposed. Let us trace the course of the vessels which carry out of the liver the two fluids sepa.. rated from the portal blood. These vessels are the hepatic duct and the hepatic vein. The hepatic duct is a tube of a firm fibrous structure, dividing into branches which lie alongside the branches of the portal vein. In the fibrous walls of these tubes are a row of small apertures, which, on being traced, are found to lead into a corresponding number of little pouches. It has hitherto been generally believed, that these pouches were for secreting the mucus of the bile, but, as Dr. Beale acutely remarks, a pouch with a very narrow neck would be a bad contrivance for a viscid secretion, besides, in those animals in whose livers these pouches are most numerous there is no corresponding increased viscidity of bile. It is more likely that they are diverticula or little gallbladders. This view seems highly probable when we consider the sudden and very copious secretion of bilc which is observed to follow the taking of food. For ex OF THE LIVER. 89 ample, Bidder and Schmidt (p. 166) observed, that while a dog fasting yielded 1558 grammes of bile in an hour, the same dog, after drinking 185 grammes of water, yielded 5165 grammes of bile in the same time. The manner in which the branches of the hepatic duct terminate has been much canvassed, and the opinion of many most distinguished investigators was in favour of the termination consisting in blind extremities; Dr. Beale, however, maintains that these ducts which carry off the bile are directly continuous with the tubes which contain the cells where the bile is secreted, and that he has succeeded in injecting the latter from the former. He has given some plates in which this is shown. Fig. b. DUCT OF LOBULE OF THE LIVER. This represents the distribution of the duct upon the surface of a very small lobule of a pig's liver, a. Duct with little sacculi in its coats. b. Small branches of the duct which are distributed upon the surface of the capsule: these are represented at least twice as wide as they ought to be. c. Inter-lobular branch of portal vein. 90 STRUCTURE AND USES That the bile is formed in these cells and does flow along these, biliary tubes, whether entering them by a free opening or by percolation through their walls, is a certain fact; but it is not known by what force the bile is propelled. Some have assumed it to be from the pressure of the full stomach upon the liver, but this notion is refuted by Bidder and Schmidt, who observed the contents of the gall-bladder and the biliary tubes to begin to discharge rapidly in a cat some hours after a meal; their opinion is that it is by a contractile power of the tubes themselves, although they have not been able either to detect muscular fibres in them, or to succeed in making them contract by galvanism. And they attribute much importance to the descent of the diaphragm during respiration. The lquestion, however, is by no means satisfactorily settled as yet, and demands farther investigation. The office of the gall-bladder is obvious enough, being simply a reservoir of bile which is emptied into the intestines at a short interval after a meal. The bile collects in it after digestion ready for a recurring demand. In connection with the hepatic duct should be noticed a system of vessels accurately described by Weber, of Leipsig, and named by him vasa aberrantia. They are most numerous at the transverse fissure of the liver, where they form an intricate net-work communicating with the larger branclws of the biliary duct. By means of this vascular reticulation the ducts arc connected with one anotherthey are, in fact, the anastomosing apparatus, and have been injected by Dr. Beale not only in the transverse fissure, but high up in the portal canals. They are thickly set with ccecal pouches, which are probahll not mucous glands, but, like those of the duct OF TH LIVER. 91 itself, little reservoirs of mimnature. bile or gall-bladders in Fig. c.

Branuches of the portal vein. c. Branches of the hepatie vein. d. Part of the capillary net-work of a lobule. 92 STRUCTURE AND USES The distribution of the hepatic vein is the converse of that of the portal. The portal divides in its course into diminishing branches and ends in capillary vessels. In these capillaries the hepatic vein takes its origin, and the smallest of its ramifications is larger than the extremities of the portal vein: thus from the first its special office of a collector, not a distributor, is indicated. Its position is about the centre of the lobule; into it the blood from the portal vein is poured through the capillary vessels lying in immediate contiguity with the liver cells, so that in its passage from the portal to the hepatic vein it has a full opportunity of being subjected to their influence. The branches of the hepatic vein unite and enlarge as they proceed outwards to the circumference, and in some animals, as the seal, which require to abstain long from breathing, they form sinuses capable of containing a large quantity of blood, so as to prevent the gorging of the liver on one hand, and of the heart on the other. After uniting into large branches they pour their contents into the vena cava inferior, the largest vein in the body, which enters the right auricle of the heart, whence it is immediately passed on to the right ventricle, and from thence to the lungs to undergo further changes. What we may call hepatic blood then is to be found only in the hepatic veins, and in a diluted condition in the vena cava inferior. Lymphatic vessels are met with in abundance in the portal canals and transverse fissure, and materially contribute to the capacity of the liver for receiving a large addition to its fluid contents without inconvenience. Thus, for example, a pig's liver may be easily made to contain a quantity of water equal to its own weight, which may be injected from the portal vein.-(Beale.) OF THE LIVER. 93 We have now described the mechanism of the liver, which may be rudely likened to a sponge placed between the stomach and the lungs, receiving the blood from the one organ and passing it on, after certain changes, to the other. To enable it to effect these changes, however, a supply of nervous force is required, and this it derives from two sources: one the cerebro-spinal, and the other the sympathetic. In the human subject this double origin is not easily demonstrated, for the cerebro-spinal nerve, the pneumogastric, is lost in the solar plexus on the right side, where it becomes blended with the great sympathetic, and on the left it is distributed on the stomach. In the dog and rabbit, however, the two pneumogastric nerves, after penetrating the diaphragm, give off distinct twigs, which accompany the hepatic artery, and become lost in the intimate structure of the lobules.--(Bernard, p. 323.) We may fairly presume that they proceed as far as the capillary network and the secreting cells. It also receives. branches from diaphragmatic, which are distributed chiefly upon the walls of the hepatic vein. The explanation of the functions of the liver, both in health and disease, hinges so much upon the fact of the double supply of nerves, that we give a woodcut from Bernard's work in which it is shown (from p. 322).1 1 Fo? the whole of the facts and the woodcuts contained in this paper we are indebted to the following interesting and important Works: Ist.

Let us now inquire into the functions of the liver, or what changes the blood undergoes in its passage through its intricate net-work of vessels on its way from the stomach to the lungs. An obvious plan of commencing this inquiry, is to subject the two kinds of blood which we call the gastric and hepatic to a careful chemical analysis, so that the difference between them may be ascertained. This has been done by Professor Lehmann, of Leipzig, whose paramount authority on questions of organic chemistry is universally acknowledged in the scientific world, and the result was communicated on the 12th of March, 1855, to the French Academy. As the matters this memoir embraces belong to science militant as distinguished from science dogmatic, it may be well to give a literal translation of the whole of Lehmann's short and satisfactory paper. 96 STRUCTURE AND USES " Comparative analysis of the blood of the vena portae and of tMe bloodl of Mte hepatic veins, -c., to serve as a history of the production of the sugar in the liver, by M. C. G. LEHMAANN, Professor of Physiological Cheemistry in the University of Leipzig. "CC The results of the following analyses have been obtained from dogs and horses taken in different states of alimentation, (care has always been taken to place ligatures round the vessels to prevent a mixture of the kinds of blood under examination). I will not delay by describing the analytical processes, which will be found in my treatise on organic chemistry; and I shall likewise abstain from certain details of the composition of the blood of the portal and hepatic vein contained in my published memoir ('Einige vergleichende Analysen des Blutes der Pfortader und der Lebervenen'). I shall only hern insist upon the points which serve to exhibit the formation of the sugar in the liver. " 1st. Surar.-The blood of the vena portm never contains the slightest trace of sugar in dogs in a fasting condition, or those fed on animal food. In the same animals fed on vegetables (such as boiled potatoes), sugar is discernible in the portal blood, but in quantities so minute as to be incapable of measurement. In horses fed upon rye-bran, chopped straw and oats, the portal blood contains slight traces of sugar. In one case I found gr. 0"055 of sugar to 100 grains of blood. In another case the serum of the portal blood of a horse contained gr. 0"052 of sugar in 100 grammes of blood. "cc The blood of the hepatic veins always contains sugar OF THE LIVER., in considerable quantity. In three dogs fed upon animal food, I found the following prbportions of sugar to dry blood: gr. 0-814 to 100, gr. 0-799 to 100, and gr. 0-946 to 100. In other three dogs which had for two days been in a state of complete abstinence, I found in the blood of the hepatic veins the following quantities of sugar: gr. 0-764 to 100, gr. 0-638 to 100, and gr. 0-814 to 100. In two other dogs fed upon cooked potatoes, the blood of the hepatic veins contained gr. 0-981 of sugar to 100 of blood in one, and gr. 0-854 to 100 in another. In two horses fed on vegetable food (hay, straw, and oats), the hepatic veins contained in one case gr. 0-635 of sugar to 100, and in the other gr. 0-893 to 100. The following table exhibits the results of the preceding analyses. QUANTITY OF SUGARB. Animals. Conditions as regards Food.

Bernard was the first to announce, is put beyond a doubt. " 2d. Pibrine. Albumen. -The blood of the vena portse in horses and dogs contains fibrine which does not sensibly differ either in kind or quantity from the fibrine of other veins. The blood of the hepatic vein if carefully collected without admixture of other blood, contains no fibrine. The few flocculi which arc sometimes obtained by beating up the hepatic blood of the horse, are almost entirely composed of white globules, which are very abundant in the blood of the hepatic veins as compared to that of the portal vein. The blood of the hepatic veins of the dog exhibits the same character as regards fibrine, that is to say, this substance almost entirely disappears in the liver. "Very careful comparative analyses of the blood of the portal and hepatic veins, have convinced me that a remarkable quantity of albumen also disappears in the liver, and that this quantity is relatively greater in dogs than in horses: upon the incontestable fact of the disappearance of the fibrine in the liver, I have established the opinion already expressed in my first memoir, that the sugar formed in the liver is derived from the fibrine. "3d. Fat and Blood globules. --The blood of the vena portae always contains much more fat than that of the hepatic veins. The serum of the portal blood in dogs fed upon animal food, is generally much richer in fat than that of horses; notwithstanding this, no more fat is found in the serum of the hepatic blood of dogs than of horses. In horses the blood-globules of the OF THE LIVER. 99 portal vein are much richer in water, and especially in iron, and on the other hand much poorer in globuline, extractive matters, and salts, than those of the hepatic veins. In dogs as well as horses the blood of the hepatic veins is much richer in blood-globules and extractive matter, than that of the portal vein. I have observed in dogs as well as horses, that a considerable quantity of iron always disappeared from the blood in its passage through the liver. But the difference in the quantity of iron found in the blood at its entrance into, compared with the quantity at its exit from the liver, is greater in dogs than in horses. It results from this that a portion of the hematine of the blood disappears in the liver, and probably goes to the formation of the colouring matter of the bile, which would prove again the complete analogy between bilifulvine and hematoidine, as one of my pupils is about to demonstrate. " Comparative analysis of the blood of diferent veins with arterial blood (all the comparisons have been made from blood taken from the same horse.) The blood which leaves the liver by the hepatic veins, always contains incomparably the most sugar of any in the body. This blood mixes with that of the vena cava inferior to mount to the heart. I can here but confirm the statement long ago made by M. Cl. Bernard, that the blood of the vena cava inferior is that which always contains the greatest amount of sugar after the hepatic veins. I found in the solid residue of the blood of the vena cava of a horse, sugar to the amount gr. 0-346 to 100, gr. 0-211 to 100, and gr. 0-492 to 100 of blood. After the blood has passed through the lungs and become arterial, no sugar is to be detected as a general rule. I 100 STRUCTURE AND USES have never found any in the arterial blood of horses, although they had been fed upon starch and oatmeal. In that of dogs and rabbits, sugar could be detected in arterial blood, if the venous blood contained more than 0-3 per cent. of it. This is the case in all the conditions in which sugar is passed with the urine; for example, in those instances after Dr. Bernard's operation, after the injection of large quantities of sugar into the veins or into the stomach, or finally in the instances of rabbits which had eaten largely of carrots and beet root. But in all these instances it is always the hepatic vein which contains most, then the vena cava, &c. "The blood of the small veins, such as the cephalic, digital, temporal, and external abdominal of the horse, contains always a smaller quantity of blood-globules and more serum, and therefore more water than arterial blood. But the blood of the larger veins, especially the vena cava inferior, contains blood of the same or even greater concentration than the arterial. All my experiments go to prove that a remarkable quantity of bloodglobules disappears in the general capillaries of the body. The equal or superior density of the blood of the vena cava inferior as compared with the arterial blood, is not due altogether to the expulsion of water by the urinary secretion, but is chiefly owing to the influx of the blood from the hepatic vein. This was shown in a striking way by the analysis of the blood of a horse which had not drunk for twenty-four hours before it was killed. The comparison of all these analyses goes to prove that two functions proceed simultaneously in the liver,-the formation of sugar, of blood-globules, and of bile, as M. Bernard has long ago established. The blood of the smaller veins OF THE LIVER. 101 contains more fibrine than the arterial blood, and than that of the vena cava and the jugular vein. In the vena cava I found only one half the quantity of fibrine that I found in arterial blood.. The arterial blood always contains more mineral salts than the venous blood." This Leipzig manifesto embraces and exhausts all the chemical elements of the question. It demonstrates the fact that the blood comes to the liver rich in fibrine, albumen, and fat, wholly devoid of sugar, and comparatively poor in blood-globules; that the blood which leaves the liver always contains a quantity of sugar, and is rich in blood-globules but not in fat, while the bile is full of fat; hence the inevitable inference that in the liver-cells the blood coming from the seat of digestion is decomposed, the fibrine certainly, and probably also some of the albumen transmuted into sugar, and passed onwards by the hepatic vein towards the hmungs, and the fat and some other ingredients separated and expelled in the form of bile. This transmutation of fibrine into sugar is utterly opposed to the theories of Liebig, which have met with so general an acceptance hitherto, that no such power existed in the animal economy, but that all the.chemical principles of the nature of sugar were only absorbed, and never generated by the purely vital forces. It would be out of place to follow up to its possible consequences this important revolutionary doctrine promulgated by Bernard, and established by Lehmann and other chemists. We have enough at present on hand in stating merely the bare facts, and before passing to the consideration of the conditions which regulate the manufacture of sugar, and the uses this sugar subserves in 1019. STRUCTURE AND USES the economy, it will be well to say a few words about its chemical character. There are many kinds of sugar met with in both the vegetable and animal kingdoms, but for practical purposes they may all be divided into two classes, according to the action of acids and alkalis upon them. The firstclass sugar, or cane sugar, is found in the sugar cane, beetroot, the maple, and many other vegetables. Its chemical equivalent is 012 H9 09 + 2HO. When brought into contact with the lining membranes of a calf's stomach, or with caseine, it is transformed into lactic acid. When boiled with diluted sulphuric acid this cane sugar is converted into sugar of the second class, known as grape sugar or glucose. This is the sugar found in the liver and hepatic veins. It differs from cane sugar in being readily acted on by alkalis, while cane sugar is not, and not being affected at all by weak acids, which decompose cane sugar rapidly. Alkalis convert it into a brown matter, and strong sulphuric acid dissolves without charring it, and forms sulphosaccharic acid. "Notwithstanding the fact," says Professor Gregory,c "that cane sugar is easily converted into grape sugar, and that the formulm differ only by three equivalents of water, it is evident that these two kinds of sugar differ more than if they wvre merely different hydrates of the same compound. Strong mineral acids instantly decompose cane sugar, but have little action on grape sugar; while alkalis which combine with cane sugar to form crystalline, compounds, rapidly convert grape sugar into dark compounds, glucic, and melassic acids. And though both sugars agree in 1 c Outlines of Chemistry,' p. 389. OF THE LIVER. 103 undergoing the same (vinous) fermentation, yet it is most probable that cane sugar before fermenting becomes grape sugar." The most certain test by which the presence of sugar can be established, is its fermentation; when mixed with yeast or diastase, it is transformed into alcohol, which may be obtained pure by the distillation of the residue, and carbonic acid which may be collected and tested as it escapes. In all instances where Cl. Bernard affirms the existence of sugar anywhere, he had ascertained it by this infallible experiment, which he performed by a simple apparatus consisting of a tube into which the substance to be tested was put in contact with yeast, while a smaller tube was passed down to the bottom of the first, and curved over it at the other extremity, where it passed through a firmly fitted cork. Thus when fermentation took place, the liquid was forced up through the small tube, and its alcoholic character determined, and the gas remaining behind was also examined. As some of the objections to M. Bernard's experiments take a chemical direction, and deny the sufficiency of his analyses, it is right at the outset to put this to rest by stating that the sugar he asserts to exist was not known only by its action on copper, &c., but by its property of fermenting. M. Bernard examined the livers of mammalia, birds, reptiles, osseous and cartilaginous fishes, and molluscous animals, and in all he found sugar. The quantity is seldom greater in health than 4 parts of sugar to 100 of fresh liver, and the average is between 1 and 2 per cent. The opportunities of investigating this subject in man are very rare, for it is only found in the bodies of those who die in a state of health, and soon after death. 104 STRUCTURE AND USES These conditions are seldom to be met with in ordinary circumstances except in criminals who have been executed. All the experiments that have been made are here represented. Date of observation. Age. Alimentation. Weiht of Quantity of Total antity the lver. sugar per cent. in liver. Kilog. Grammes.

If these results stood alone it might give rise to the suspicion that the presence of sugar in the liver of a person dying by violence was an attendant upon the mode of death, and did not represent the natural contents of that organ. But when we take into consideration that in all the animal kingdom the liver is found to contain sugar, and that it disappears very readily under the influence of very many morbid conditions, the natural and fair inference is, that man is not an exception to the general rule, but that what is exceptional, is having an opportunity of examining the body of a healthy person recently killed; and as when this exception is met with, it corresponds with what our previous knowledge of the liver of animals led us to OF THE LIVER. 105 expect, the exception in this case certainly confirms the rule. That the character of food has not much influence upon the quantity of sugar contained in the liver, is shown by the following table: Per centage of sugar in liver. 1st Dog fed on animal food... 1-90 2d,,... 1-40 1st Dog fed on animal food and bread. 1-70 2d,,,,... 1-30 3d,,,,... 130 1st Dog fed exclusively on faecula and sugar 1-88 2d,, for 6 days exclusively on sugar 1-50 In all these examples the dogs were killed at the same period of their digestion, and the experiments show that the nature of the food made only a fractional if any difference in the quantity of sugar. That a sugar diet had hardly increased the sugar in the liver, and that a purely animal diet did not diminish it. In carnivorous animals there is a great difference in the quantity of sugar which passes into the blood at different times. When digestion is not going on, the quantity delivered by the hepatic veins is about 1 per cent., which when this blood is further diluted in the right auricle is much diminished in proportion, and entirely disappears after the blood passes through the lungs; but after a full meal the liver is filled like a sponge, and its activity greatly increased, so that there is a great augmentation in the quantity of sugar it delivers, not all secreted at the time, perhaps, and when a certain excess arrives at the lungs, it is not 106 STRUCTURE AND USES all destroyed there, but some passes into the arterial capillaries, and is found in the excretions. If the early appearance of a function in the foetus, and its universal distribution over the whole animal kingdom be a proof of its importance, then unquestionably the sugar function in the liver must rank very high among the vital actions, and such being the case, it is surprising to find that it is so easily arrested. It seems that all morbid states attended with fever, immediately put a stop to the formation of sugar. This is the explanation of the disappearance of sugar in diabetic patients when they are attacked by some acute disease, a change in their condition liable to be mistaken for an improvement, although it is generally the reverse. It is probably to this arrest of the sugar formation in the system by fever, that the rapid loss of strength is due in that process, for, as we shall afterwards see, the sugar seems to be one of the primary requirements for the renovation of the body; and we all know how wonderfully rapid is the decline of strength in fever, so much beyond what any mere loss by perspiration or otherwise could account for. It is not that the body wastes; properly speaking, it is that it is not made. Besides acute disease, many external unnatural conditions have the same effect. If an animal be exposed to intense cold, either by immersing it in a freezing mixture, or by coating its surface with varnish, so as to destroy the non-conducting efficacy of its fur, in the course of a few hours there is a total disappearance of sugar from its liver. Heat at first augments the quantity of sugar produced; but if intense and long continued, it exerts the same influence upon it as cold. As a general OF THE LIVER. 107 rule, abstinence from food lessens the quantity of sugar pari passm with the diminution of the whole mass of blood; but the sugar entirely disappears a considerable time before the death of the famished animal. However, there is a remarkable exception to this rule in the case of hybernating animals. In a marmot the quantity of sugar was found to be in its usual abundance after thirty-nine days' total abstinence. In the stomach of this marmot a neutral brown fluid was formed, and from this Bernard supposes the blood derived the materials for having sugar made at the liver. In other animals long before death by starvation the stomach is perfectly empty. It is rather singular that while the liver should be so delicately affected by general causes which affect the whole system, such as fever, as to have its glycogenic function rapidly arrested, yet that the formation of sugar should go on with unimpaired vigour when the whole substance of that organ presented the characters of the well-known foie gras.' Even the existence of cysts, hydatids, and cancer in the liver, does not prevent the formation of sugar in those parts which are not the imamediate seat of the disease. Endowed apparently with remarkable general sympathies in respect to other organs, especially the lungs and spinal cord, it seems to have little internal relationship with itself. This may be accounted for by its anatomical structure; and it may, perhaps, be looked upon rather as a congeries of little formations depending on central influences, like a group of island dependencies upon an empire, than as one large 1Lereboullet sur le Foie Gras. 'MCui. de 1'Acad. de Med.,' Paris, t. xvii, 1). 4.77. 108 STRUCTURE AND USES independent organ. Be the explanation what it may, the facts that a liver greatly diseased may yet continue to produce sugar, and that this important operation is instantly suspended whenever fever invades the frame, are of paramount practical interest. We have already given a tabular view of the comparative effect of different kinds of diet upon the formation of sugar. This, however, was rather to establish the fact, that the sugar which was found was not contained in the aliment. The influence of various articles of food upon the glycogenic function of the liver has been more fully examined, and yielded interesting results. In the first place, Bernard found that fat is incapable of conversion into sugar. Dogs fed on fat soon lost all their sugar; so that, in a certain superficial way, the dietary of Rollo for diabetic patients is justified by these experiments. No doubt feeding a person on fat will prevent the formation of sugar at the liver, and consequently cause its disappearance in the urine; but as diabetic urine is merely a symptom of some profound lesion of the nervous system, probably the so-called cure is nearly as deceptive as is the disappearance of the sugar in a diabetic patient attacked with acute disease. In neither case does the absence of the symptom indicate the non-existence of the thing signified. The fog that prevents the danger-signal from being seen does not contribute to the safety of the line, nor does the suppression of indications of danger by allopathic expedients secure the safety of the patient. In the second place, he found that pure gelatine and albumen, so far from reducing the quantity of sugar below its average amount, had rather the opposite effect. This, how OF THE LIVER. 109 ever, although at first it excited his surprise, is what we should now expect to have been the result. But the experiments with the remaining one of the three primitive elements of diet, the sugar and starch group, gave most unexpected results. He found that, although at first dogs did not like an exclusively starch and sugar diet, yet after a few days they got used to it, and it seemed to nourish them; and on examining the liver, there was no excess of sugar found there, but almost exactly the same quantity as when the dogs had been fed exclusively on albumen. One of the dogs was fed for three days with potatoes and starch, and killed three hours after the last meal. In the liver the proportion of sugar was 1 88 to 100 parts; but the liquid obtained from the liver, instead of being clear, as is usually the case, was of an emulsive and opalescent appearance. The sugar had been absorbed from the stomach and intestines, and had been carried by the vena portaw to the liver, but it had not there been converted into the true diabetic or grape sugar, and continued to mix with the blood in a sort of transition state between cane and grape sugar; no more than the average quantity of hepatic sugar being formed out of this exclusively sugar diet. This demonstrates the futility of the attempts made to cure diabetes by withholding feculent food. Whether animals live on starch or albumen makes little difference in the amount of sugar delivered by the hepatic veins into the vena cava, but other conditions have an immense influence, and chiefly the nervous system. The action of the nervous influence upon the liver has been demonstrated by Dr. Bernard, by a series of experiments not less distinguished for ingenuity of design than o1.0 STRUCTURE AND USES for anatomical expertness in their execution. The liver, as we have seen, is chiefly supplied by the pneumogastric nerves. These nerves have their origin in the medulla oblongata, behind the olivary and very near the restiform bodies, by one or two rows of filaments from five to six lines in length, and disposed in regular order. After leaving the skull they accompany the internal jugular vein; on entering the thorax there is a difference in the distribution of the right and left pneumogastric nerve. However, they are both lost in a plexus of nerves situated upon the stomach. From this plexus the liver derives its nerves. Before descending to the organs of the abdomen, however, it gives off large branches, which supply the lungs. In the rabbit this nerve gives off a distinct branch after supplying the lungs, which goes to the liver; so that in that animal there is a double nervous distribution, the one direct from the main trunk of the vagus, the other from the plexus of the stomach. When the pneumogastric nerves are cut in the neck, and the animal is killed on the day after the operation, no sugar is found in the liver. The first explanation of this effect that offers itself is naturally that the nerves so divided were the channels by which a vital 'force was conveyed, which the liver required to enable it to convert the fibrine of the blood into sugar. In that case substituting a current of galvanism might have the same effect. This was accordingly done, and Bernard found that when the galvanic stream was directed downwards to the liver it had no influence, but if sent upwards towards the origin of these nerves it restored in an exaggerated OF THE LIVER. 111 degree the glycogenic action of the liver. The following explanation of this was pro'posed. The pneumogastric nerve is a mixed or compound nerve; on the one hand it transmits an influence from the centre to the circumference, giving rise to muscular contraction in the oesophagus and to secretions in the stomach; while on the other hand it carries inwards impressions received in outlying organs, and transmits them first to the centre, and where they may be perceived and give rise to sensation, or from whence they may be at once forwarded, without being read off like a telegraph message, to some other outlying organ. The two organs in this instancewhich are thus united are the lungs and the liver. Before the liver will act it must receive a message from the lungs; but if the pneumogastric nerves are divided in the neck then the lungs are cut off from the centre, their call for aid is not taken up to the brain, and therefore cannot be sent down to the liver. In order to test the correctness of this explanation, Bernard performed a crucial experiment. He divided the branch of the pneumogastric in the rabbit, which comes off from the main trunk at a point below the origin of the pulmonary branches. The place will be seen at once in the diagram (p. 94); it is marked r. By doing this he left intact the circle from the lungs to the liver by way of the spinal cord, but he cut off the direct influence of the brain from the liver. The result was that the formation of sugar went on at the liver. Thus it is an ascertained fact that the stimulus given to the liver by which this special function is called into play begins at the lungs. Before this experiment, Dr. Bernard had instituted a series of most interesting ones upon the effect of irri 112 STRUCTURE AND USES tating by a sharp-pointed instrument the portion of the spinal cord whence the pneumogastric nerves arise. The exact spot where the wound was made is limited by a line drawn transversely above from one of the tubercles of Wenzel to the other, and below from the two sets of the pneumogastric nerves. After the operation "the rabbit looks a little astonished at first," (semble etre un pen etonne sur le moment), but it soon recovers its senses, and it does not seem to be the worse. The effect of this irritation or wound of this portion of the spinal cord is, that in the course of an hour or so the urine is diabetic. We are now prepared for this effect; but when it was first announced it had a most startling effect. The explanation of the effects of the operation is simply that an extraordinary excitement was produced at the centre, simulating the ordinary stimulus which goes from the lungs to the liver through this centre, and that in consequence the liver discharged a greater quantity of sugar into the hepatic veins and vena cavae than the lungs could use up, and the excess was passed on by the arteries of the body; from one of these arteries (the renal) the kidney separated it, along with the water in which it was held in solution, and hence the diabetic urine. That such is the true explanation of the phenomenon of artificial diabetes is certain; and it is highly probable that when this disease is' met with it depends upon some diseased state of that part of the brain from which the pneumogastric nerves take their origin, and it is therefore not likely to be cured by feeding patients on bread made of gluten, or by means which tend to affect the symptom, not the cause. OF THl LIVER.1 113 Fig. -5.,P CC IrI R C -......T THIS MIAGRAM ILLUSTR&TES THE WHOLE PROCESS OF DIABETES. The source of the saccharine matter is the liver (F.) where it is produced, and in the substance of which it is always to be found. The liver receives the materials to make sugar from the blood which is brought by the 8 114 STRUCTURE AND USES vena port.a (V. P.), and which contains no sugar in carnivorous animals. This blood consists in part of the blood of the mesenteric arteries, which passes by the capillaries into the branches of the vena porte at b, and somep of this blood is made up of the materials absorbed directly at a from the intestine at I. The unsugared blood of the vena portic (V. P.) enters into the liver, diffuses itself there, is subjected to metamorphoses in contact with the elements of the gland, becomes full of sugar, and then passes into the hepatic vein (I-I. S.). We have thus the blood entering the liver at V. P. (the portal vein) without containing a particle of sugar, and full of it at H. S., where it leaves the liver. The sugar then must have been generated at the liver. The sugared blood of the hepatic vein (H. S.) then arrives at the vena cava inferior (V. C.I.) near the heart, mingles with the nonsugared blood of the vena cava, and enters with it into the heart (C.), where it again mixes with the blood of the vena cava superior (V. C. S.); so that the quantity of sugar is diluted from being in the proportion of 0'980 to 100 at H. S. to 0-300 to 100 at the heart (C.). The sugared blood of the right ventricle (C.) is driven through the lungs by the pulmonary artery (A. P.), it arrives at the capillaries of the lungs (P.), where the sugar is almost entirely destroyed, the blood returns to the left side of the heart by the pulmonary vein. Thence the blood, having thus lost all its sugar, passes by the arterial or aortic system (A. A.) on to the general capillaries of the body (C. C.). There the blood undergoes further changes, and becomes converted into venous blood, to return by the vena cava superior and inferior (V. C. S., V. C. I.). The blood of the mesenteric artery (m) expands in capillaries upon the intestines, and absorbs from the intestine the matters there dissolved at I, and then goes on to the liver. The blood of the renal artery (R.) arrives at the kidney (R.), and yields the products which form urine, but has no sugar to give in its normal condition. This only happens when the quantity of sugar contained in the right side of the heart is more than 0-300 to 100, for this is all that the lungs can destroy. When more than this the excess passes into the arterial circulation, and the renal arteries carrying sugared blood deliver the same to the kidneys. The xidneys then become eliminators of sugar, and the individual diabetic. It is now an established fact that there is a constant formation of sugar at the liver, and an equivalent destruction of that sugar at the lungs, in health, and that this subterranean operation is only manifest either when the liver yields too much or the lungs consume too little. The questions that remain to be considered are, what OF THE LIVER. 115 becomes of the sugar, and what purpose does it serve in the economy. The first supposition was, that, as sugar was a very combustible material, it was united with oxygen at the lungs, and was emitted thence in the form of carbonic acid, and some experiments seemed to corroborate this hypothesis. It was found that animals became diabetic on the administration of ether and chloroform, which was ascribed to the inability of the air loaded with these vapours to consume the sugar, which accordingly passed into the general circulation. However, Bernard demonstrated the fallacy of this theory, which at first he felt inclined to adopt, by exposing blood which contained sugar to the action of various gases. He divided a quantity of blood taken from the jugular vein of a dog in a state of digestion, and consequently sugared, into three equal portions; one he mixed with oxygen, one with nitrogen, and one with carbonic acid gas. The sugar disappeared in the portion mixed with nitrogen, but was unaffected by the oxygen and carbonic acid. We cannot detail his other experiments, but they were quite enough to satisfy him that the disappearance of the sugar was not owing to a conversion into carbonic acid at the lungs. Neither was it owing to the action of the alkalis of the blood. It is true that the blood always is alkaline, and that an acid, or even neutral, condition of the blood is incompatible with life; but it was chemically demonstrated by Lehmann that the amount of alkali in the blood was not enough to destroy the sugar. The explanation proposed and accepted by M. Bernard is, that the disappearance of the sugar at the lungs is owing to its transformation into lactic acid by a species of fer 110) STRUCTUIRE AND USES mentation. The chemical constitution of the two is isomeric. Sugar being represented by C1,,H.i,O,, and lactic acid by C1,Hi0,00,,,+HO, or an atom of water; and this precise transformation may be imitated in the laboratory by mixing sugar and yeast, prepared in a particular way, when instead of converting the sugar into alcohol and carbonic acid, it changes it into tartaric acid and water. Up to this point we have advanced step by step upon a series of facts, or what we must accept as facts until they have been disproved by counter-experiments and observations; but we now enter the region of conjecture, and although we may admit that M. Bernard's suggestion of the purpose the sugar he unquestionably discovered to be formed at the liver serves in the animal economy is extremely ingenious, perhaps perfectly true, yet it would be unjust to him as well as to science to place it on the same level as his great discoveries. The explanation he offers is this. If we take yeast and pass it through a filter, the filtered liquid will contain albuminous matter;- now if we divide this fluid into two parts, and to one add sugar, and to the other nothing, in the course of a certain time the sweetened liquid gets turbid, and minute egg-shaped bodies appear in it, which gradually enlarge and give off similar bodies like themselves, until at length a sort of chaplet is formed, more or less simple, or branched, as may be. No such change takes place in the other portion. We have here the most primitive development of the vegetable kingdom in the form of this fungus, which appears when sugar and dissolved yeast granules are left in contact at a sufficient temperature. If instead of OF THE LIVER. 117 yeast we take a little serum of the blood, and divide it into two portions, exposing both to a sufficient temperature, but to one only adding sugar, we shall find that, in the course of four or five days, the unsugared portion has putrefied, but the sugared has had formed in it a quantity of cellules, not like the little cells that appeared in the yeast, but having a. close resemblance to the white blood-globules. Here then is a sort of animal germination in the presence of sugar. If we follow up this hint, we find that throughout the vegetable kingdom the phenomenon of germination is invariably attended by sugar; and if we examine the animals in the foetal state, we find that in all the muscular tissues and in the lungs there is a large quantity of lactic acid when soaked in water; but when treated with alcohol, instead of lactic acid we meet with glucose. The object that the sugar always present is supposed to serve is to present to the tissues during their formation the materials of their growth in a sort of nascent condition. Sugar, as we know, is a very unstable compound; it is very readily decomposed; it is in a state of constant fermentation, as the word is popularly used; and if a substance is brought in contact with it, deand recomposition are quickened. Thus it promotes life by a sort of catalytic action, imparting to what it approaches the molecular restlessness of its own nature. In this way it is supposed to promote the formation of blood-globules in the liver, and serves as the nursery of the body. While the genius of Bernard has thus disclosed the wonderful action of the liver in forming sugar, the labours of Professors Bidder and Schmidt have been directed to 118 STRUCTURE AND USES ascertain the history of the complementary function of that organ in the elaboration of bile. The sugar and the bile have this in common, that while the whole of the former is disposed of in the vital processes without appearing at the surface, except in morbid conditions of the system, the latter too is partially used up in the same way, while the remainder is cast out as refuse. In order to determine the exact quantity of bile secreted, and what became of it after it was poured into its proper channels, it was necessary first to institute a series of experiments to collect the bile as it was made in the liver, and this was done by introducing a tube into the bile. duct of various animals, measuring and analysing it, and comparing the conditions of the animals when deprived of their bile with their natural state. Bidder and Schmidt fomud that when the tube which gave them the command of the bile was successfully introduced, it did not materially affect the health of the subject of the experiment; and although the experiments in some respects have been considered fallacious, yet enough of undisputed conclusions remain to make the results highly valuable. The bile is a clear fluid, varying in colour from golden yellow to grass-green. These variations depend upon the nature of the food and the action of the substances it is in contact with. The yellow bile is the result of animal and the green of vegetable food, but the clearest yellow becomes green very soon when exposed to the action of the atmosphere, and when retained for many hours in the gall-bladder, but the bile of the gall-bladder taken two and a half to three hours after a meal is as yellow as that taken directly from the liver. We may thus ascertain whether ejected bile has been long or recently secreted OF THE LIVER. 119 by the colour it presents, if we know what the person has been eating. When first secreted the bile is always neutral, and it derives any alkaline character it may afterwards acquire from the mixture of mucus from the gall-bladder. As to the quantity of bile secreted in a given time, for example, in twenty-four hours, this is only approximately ascertained by comparing the amount of different periods after food is taken. The following table shows the fluctuation it underwent in a cat. One kilogramme of cat afforded in one hour: Hours after the last meal 21-3 12-16 24 48 72 168 240 Of fresh bile (grammes) 0-600 0-807 0-410 0-291 0-179 0-153 0-094 Of dry residue... 0-033 0-045 0-025 0-020 0-018 0-011 0-007 From this table, which is only one of many that give the same result, it will be seen that immediately upon taking food there is an increase in the flow of bile, be-- fore digestion can have taken place to such a degree as to have at all enriched the blood with chyle, and, consequently, simply from the greater quantity of blood which the stimulus of food retains in the organs where it is first received; that this increase gradually augments and reaches its maximum from twelve to fifteen hours after a full meal, by which time, probably, all the products of the digestion have been received into the blood. At this point a diminution begins in the amount of bile secreted, so that in twenty-four hours after the meal the quantity is far less than two hours after. From these data we may strike an average of the daily secretion of bile in the cat with tolerable exactness; and this gives 0-608 grammes of fluid bile, and 0-034 grammes of dry to a 120 STRUCTURE AND USES kilogramme of cat. A dog yields one fiftieth of its weight in the day, and a rabbit no less than one eighth of its weight. It is most probable that a man yields about the same proportion as a dog: this would give about 60 ounces to a man of ten stone. We may observe in passing that there is a partial but not complete coincidence in the increase of sugar and bile delivered by the liver. The sugar at once attains its highest amount after a meal is taken, but although even then the quantity of bile secreted is much above its average, yet it does not attain its maximum till long after the sugar has begun to diminish. Let us now consider what becomes of all this bile that is poured into the intestines. Does it pass off by the alvine channel or by the kidneys? An analysis of the solid constituents of bile disproves the latter supposition: they are not found in the urine. But they are in the feces, but not nearly the whole quantity. In order to ascertain this, the quantity of solid matter yielded daily by a dog fed on animal food was accurately determined, and then the faeces were subjected to a careful analysis. The result is shown in the following table: Water.... 56-4 grammes. Solid residue....40-9 Of these neutral fat soluble in ether.. 2-82 S Fat with traces of bile 4-97,, Bile products soluble in alcohol.. 380 In this organic matter.. 3-42 with 0-70 sulph.,, inorganic,,.. 038 grammes. OF THE LIVER. 121 Extracted by muriatic acid and boiling alcohol: Not derived from the bile. 9'60 grm. with 0'084 sulph. Fat, oils, acids, and ox. of iron.. 6-35 Hair, sand, &c.. 13-36 40-90 From this it is proved with absolute certainty that the larger part of the bile discharged into the intestines is there absorbed into the blood, for only a small portion of the 40 grammes of solid residue of the faeces was derived from the bile, while the quantity of solid matter delivered in the same period was nearly equal to the whole of the faecal residue, being 39 grammes, while the other is only 40. The fact is brought out by attending to the Sulphur. In the 39 grammes of solid bile discharged by the liver in the five days into the intestines,- there must have been 2"37 grammes of Sulphur: now the whole quantity of Sulphur contained in the faeces was only 0"384 grammes, and more than half of this was derived from the hair, &c., so that almost all the Sulphur which is contained in the bile is absorbed by the blood again, and about seven eighths of the whole of the solid contents of the bile. As the bile then does not obtain an exit by the alvine or urinary channel, there remain but the lungs to be examined. Bile consists chiefly of a feeble acid called bilic, or cholaic combined with soda. The composition of this acid is thus atomically represented: C44, H26, NOi3, = C41, H25, N012, 110. (Gregory). We 122 STRUCTURE- AND USES see from this what a large proportion of carbon there is in bile, and we know that carbon is being constantly emitted from the lungs in the form of carbonic acid; hence the conclusion is irresistible, that the expired air must carry off a portion of the secreted bile. Some chemists have gone so far as to declare that all the carbon discharged from the system passes through the liver, but this undoubtedly is not the case; for a dog fed on animal food yields at the rate of 8-6 grammes of carbon for every kilogramme of its weight in the air it expires, while during the same period the liver does not discharge above 1 gramme of bile into the intestines, and out of this not above 0"5 grammes of carbon are absorbed by the blood. So that about six per cent. only of the carbon which is given off by the lungs as carbonic acid comes from the liver. Let us now consider the uses of the bile in the animal economy; a subject only imperfectly known as yet, notwithstanding all the labour and skill which have been brought to bear upon it. From the following description of the effects of depriving a dog of its bile we may gather much information; it is given by Bidder and Schmidt, and is a fair specimen of what was generally met with by them in the whole series of their experiments. After an opening had been made in the side of the dog, and a tube inserted intothe hepatic duct, which received every drop of bile furnished by the liver, and carried it outside, where it was of course of no use to the dog; for the first two days the animal refused its food and seemed much indisposed; but from the third day it ate greedily of flesh to the amount of 160 and even 403 grammes a day. The weight of the dog at OF THE LIVER. 123 the beginning of the experiment was 6 kilogrammmes, and at the end of a month it weighed only 3"10 kilogrammes. In thirty-four days it had lost two fifths of its weight, notwithstanding the large quantity of flesh it had consumed. The emaciation proceeded gradually from the first, and consisted chiefly in the disappearance of all the fat, so that the muscles of the body looked like long ribbons seen under the skin, which hung in loose folds over the skeleton. The muscles too wasted away, and there was great feebleness of movement from the first. The hair came out in handfuls and left bare patches. Durii'ig the whole of this miserable spectacle the digestion seemed to go on with perfect regularity. The alvine evacuations were infrequent, at first slimy and white with gray and green portions, but latterly of the normal colour and consistence; but during the whole 1)eriod they had a strong assafretida smell, owing to the putrefaction of the food in the intestines. Although the breath Was also most fetid and disagreeable during the whole of the experiment, there seemed to be no tendency to dissolution of the fluids, as there was neither ecchymosis nor haemorrhage. The urine was small in quantity, but of high specific gravity. Notwithstanding the extreme emaciation, the dog retained its animation to the last, and although it could hardly stand, it rose when we (i.e. Bidder and Schmidt) entered the laboratory of a mornitug and followed us to the balance. There was no disturbance either of the respiration or of the heart's action, but a most marked decrease of animal heat: a thermometer inserted into the rectum indicated 34-6 C. degrees, and fell even so low as 29 C. The death of the animal was without a struggle. On dissection, the body 124 STRUCTURE AND USES disclosed no abnormal appearance of importance, except the almost absolute absence of fat and thinness of the muscles. The naked eye could not detect an atom of fat in the cellular tissue under the skin, and it had entirely disappeared from the kidneys. It would seem from this that this dog, although largely fed with its appropriate food, was simply starved to death, because, although it could digest, it could not assimilate its meat when deprived of its bile. Besides being starved, it was made cold by cutting off some of the charcoal which should have been burned at the lungs. Let us now end.eavour to ascertain how it was starved by its bile being cut off, in other words, to the assimilation of what portion of the aliment bile is essential. Taking the usual division of food into the albuminous, the feculent, and the oily, Bidder and Schmidt made the following experiment to determine the action of the bile on each species. They gave a dog, which they had absolutely deprived of bile, 3-035 kilogrammes of liver and lungs, from the 29th of March to the 2d of April. This quantity of flesh contained 806"8 grammes of solids, of which 693"2 grammes were albuminous and salts, 113 6 grammes were fat. The alvine evacuations of this dog during that period yielded 124 grammes of solids, of which 72"2 grammes were fat, and only 51-8 grammes were albuminous matter and salts. The difference between 693.2 and 51"8 represents the quantity of albumen digested by the dog in these five days without the aid of bile. From this and similar experiments we may conclude that it is not in virtue of its action on the albumen of the food that bile is required for its assimilation. Another dog was fed for eight days upon black bread. OF THE LIVER. 125 The alvine evacuation was very voluminous and had an acid reaction; on being tested with iodine to determine whether starch was present, only a few blue spots appeared here and there, and not more than was observed in similar circumstances in a dog in its normal condition. The dog increased in weight, and the same observation was made in an experiment with another dog fed upon white bread after its bile had been withdrawn. In this, for instance, in eight days the dog increased in weight from 5-325 to 5-590 kilogrammes. The inference drawn from this seems undeniable, that feculent food can be perfectly digested without the assistance of bile, and that it therefore takes no part in the assimilation of this portion of the aliment. The influence of the bile upon the fat alone.remains for consideration, and that fat too can -be assimilated without it, is proved by the experiment first detailed. This dog, whose weight was 5300 grammes, received in the first series of observations 95 grammes of fat in eight days, and in the second, 41-4 grammes in five days, while there were found 85 grammes of fat in the alvine evacuations in the first experiment, and 72 grammes in the second. So that in one case the dog assimilated 11-88 grammes of fat daily, and in the latter 2"24 grammes. Similar results were obtained by Lenz, who made many experiments on this subject, which are published in his thesis.' Although there can be no doubt from these experiments that some fat may be absorbed into the system without the action of the bile, yet it would seem that the quantity is far less than when this secretion is present. For a dog not much larger than S De adipis concoctione et absorptione diss. inaug. Dorpati, 1850. 126 STRUCTURE AND USES the one previously employed, absorbed no less than 446'9 grammes of fat in five days, which is about seven times as much as was possible for the dog to do when deprived of its bile. That bile enables fat to be received into the animal economy seems to be an established fact; but the method of its operation in this process is still a matter of uncertainty. It evidently influences the absorption of fat by the lacteals, for while the average of fat in the chyle is 32 per mille, it was only 2 per mille in animals deprived of their bile. If the fat were acid the soda of the bile might neutralize it, and it does when this is the case: but the fat for the most part is neutral, so it is not in this way it acts. Nor does it act by making a sort of emulsion with oil globules as has been supposed, for such an emulsion would not be more easily absorbed than fat in a state of minute division. Its true mode of action, according to Bidder and Schmidt, is by moistening the epithelial cells of the mucous membrane of the intestine, and so disposing them to permit the permeation of the oil-globules: without this the fat is not absorbed. Its action is thus purely mechanical, and affects the molecular attraction of the interstices through which the oil passes, and may be imitated by moistening a capillary tube with bile, and dipping one end in oil, while a dry tube of the same diameter is similarly placed; the oil rises higher in the tube moistened with bile than in the other. Thus it would seem that an animal actually dies of starvation, because it cannot absorb fat without the aid of the bile; and one of the chief offices of the bile is to lubricate the passages by which the fat passes into the blood! The inordinate appetite observed in dogs deprived of OF TIE LIVER. 127 the use of their bile, arises from an instinctive perception of the large quantity of food that is required to compensate the want of fat which should have been absorbed. Hunger is one of the constant effects of a deprivation of bile. The exact difference in the quantity of albuminous diet required to sustain a dog in its full weight without the aid of bile, is thus computed: a dog of 4 kilogrammes in weight consumed daily 250 grammes of flesh; and now, by direct experiment, it was ascertained how much carbonic acid this dog expired, and the quantity represented 34"36 grammes of carbon in the day. If the flesh he ate had been pure albumen, it would not have been enough to meet this consumption at the lungs, for it would only have given 27 grammes of carbon, but the deficiency was made up by 19 grammes of fat, which gave 15 grammes of carbon. This, with the carbon contained in the salts of the meat, was sufficient for the demand at the lungs. The dog got 39 grammes of carbon in all, and only required about 34. But how was it with the dog that had its bile turned off? It was found to consume 47 grammes of carbon at the lungs in a day; but it lost 3-5 grammes of carbon by the escape of the bile, which had also to be made up, so that its demand was 50 grammes of carbon a day. Now all the fat he could get into his system, owing to the want of bile, was 10 grammes a day, yielding 7"8 grammes -of carbon; so that there was a deficit of 42 grammes of carbon to be made up by a corresponding increase in the quantity of albumen, to no less an amount than 400 grammes of raw meat to cover this enormous loss of carbon. This dog actually consumed 525 grammes of flesh, and required it all to keep him 128 STRUCTURE AND USES self in condition, while his fellow who had the use of his own bile, required only 250 grammes: hence the hunger. It would, however, be an error to suppose that the only function of the bile was the assistance it gave the system in the absorption of fat; undoubtedly, after its absorption, it discharges most important offices, in aiding those wonderful transmutations by which the external materials, out of which the body is made, are converted into flesh and blood. But into this mysterious region chemistry cannot follow; it notes its entrance and awaits its exit; but what transpires in the secret chambers of life, where conception is constantly going forward, is beyond its utmost efforts to penetrate. Again we see the fallacy of hoping to find in chemistry, a key to the cure of the morbid alterations in the vital actions, from which even in their normal state the chemist is entirely excluded. The chemist tells us that in the bile absorbed, there is always a minute quantity of sulphur, and that this sulphur plays an important part in the transformation of the tissues; but this is all, and the physiological chemists most candidly confess that there are probably an infinite number of uses of the bile within the economy, of which they know absolutely nothing. We have seen how important was the action of the nervous system upon the glycogenic function of liver, and we cannot doubt it is equally potent in its influence upon the quantity, and probably also the quality of the biliary secretion, as shown by the sudden yellowness of the skin from anger or jealousy: but, of all this, beyond the naked facts, we know absolutely nothing. Even of the much more accessible department of know OF THE LIVER. 129 ledge-the influence of different kinds of aliment upon the quantity of the bile secreted-we know extremely little, and that little provokingly proves that this influence is very great. In the series of experiments made by Bidder and Schmidt to ascertain the effects of discharging the bile directly from the liver, and depriving the animal of it, the effects upon the quantity secreted within a given time by different aliments, are noted by the way, and afford some curious and interesting, although imperfect information. The most certain fact ascertained was, that abstinence rapidly reduced the quantity of bile secreted, while flesh and water, on the contrary, as certainly increased it. That eating flesh should do so is not surprising, but that purewater should augment not only the quantity of fluid bile, but of its solid constituents, was an unexpected result. The following table exhibits the fact. While fasting the Dog yields. Fed. Now yields. Day of experiment.

Here is an important fact for the Water-cure! The effect of lard and butter was rather to diminish the quantity of bile as compared to the effects of a meal of flesh; but it would be rash to draw too many inferences from tables recording experiments made for a different purpose. The difficulty of the subject is very great, but as the zeal of experimental physiologists seems setting at present towards the liver, we may hope for much important addition to the present stock of our knowledge in regard to the action both of alimentary and medicinal agents upon this important organ; and we cannot but look forward. with hopeful anticipation to a rapid increase in our practical ability to cope with the multitude of affections which depend more or less upon some disorder of the hepatic structures, when we are made more fully acquainted with the value of each of its functions, the methods of gauging their efficiency, and recognising their aberrations, so as to bring them under better control, by more enlightened management and medication.. CHAPTER IV. ON DIGESTION. THEsE are bad times for the young and earnest physician of the old school of medicine. Let him round the circle of the sciences; let him master the stethoscope and the microscope; let him perfect himself in all chemical knowledge; let him understand the most occult anatomy of the body of man and of all living beings; let him advance into physiology as far as it is possible for him to penetrate, and if he then attempt to apply all these vast acquirements to the simplest problem his patient gives him to solve, by asking him to explain how he digests a mutton chop and a potatoe,or why.he can't do it,-which is the more likely form of the interrogation, our young philosopher will be compelled to make the humiliating confession that from the moment these representative constituents of the material of the flesh and blood enter the mouth till the period of the accomplishment of their mission, their analysis, appropriatioi, and rejection, every stage of their progress presents subjects for controversy so keen that, but for the improvement in the manners of this age, we should have discoverers brandishing their knives at one another, and only too thankful that they escaped the fate of George Wirsung, who was assassinated for his 132 DIGESTION. daring innovations about the pancreas. " Wirsung mourut assassine, dit on, le 22 Aoit, 1643. Nous constatons de nouveau ici que les decouvertes anatomiques et physiologiques suscitent aujourdhui moins de passions." So says Bernard in Paris, and we fancy we hear I-errn Bidder and Schmidt mutter, " Gott sei dank" from Dorpat. For there is scarcely a single proposition made by the brilliant Frenchman that is not met either with a point blank contradiction by the patient painstaking Germans, or at least subjected to very rude handling. And the subjects of these controversies are not minute or trivial, but no less that the effect of almost every different agent on the fecula, the albumen, and the fat from the entrance of these substances into the mouth till their disappearance in the intestines. They differ about the action of the saliva upon the fecula, about the action of the gastric juice upon the albumen, about the action of the pancreatic fluid and bile upon the oil and upon the albumen. We shall not be guilty of the presumption of attempting to decide which is in the right, but shall satisfy ourselves with stating the most important conclusions that each party has arrived at, leaving to future investigators the ultimate decision. And we do not think that it is a waste of time to discuss these matters, even although we cannot arrive at positive and final opinions upon them, for among the various knowledges we do well to acquire there is none more important than the knowledge of our ignorance. Without farther prologue we shall at once proceed to detail the observations of Bernard, and Bidder and Schmidt, upon the action of the different agents to whose DIGESTION. 133 operation every kind of food is exposed in the process of digestion. The first of the long series of changes which food undergoes to prepare, it for incorporation takes place in the mouth where it is subjected to the process of mastication and insalivation: the former being a purely mechanical division of its parts so as to form a mass "which can be easily swallowed, the latter being partly mechanical in so far as the lubrication of the mass is concerned and its admixture with the air, and partly probably chemical from the action of the saliva upon the fecula it may contain. This saliva, which is generally spoken of as a simple secretion is, in fact, a combination of three secretions derived from three different glands, and each of the three possesses peculiar qualities. The first we shall consider is the secretion from the -parotid glands. This consists of about 95 per cent. of water, and its action according to Bernard, is to facilitate mastication. He found that after its obstruction in the horse the animal took much longer to eat its hay, oats, and straw, and that the quantity of the secretion was in proportion to the dryness and hardness of the food. Thus while eating 250 grammnes of bread in 3 minutes, 185 grammes of parotid fluid flowed from the ducts, which were exposed so as to be. subjected to experiment, while no less than 932 grammes were secreted in 12 minutes when the horse was masticating hay. The absence of this secretion increases the thirst in a marked manner, so that an animal which before the obstruction was satisfied with about 20 kilogrammes of water in the day, required after the operation about 30 kilogrammes to appease its thirst. And this thirst does not 134 DIGESTION. arise from dryness of the fauces, for the mere swallowing of water has no effect in abating it, if that water does not reach the stomach and intestines, as happens when an artificial fistula is made in the cesophagus. Thirst is a general not a local appetite, and can only be satisfied by increasing the fluids generally. The parotid fluid is a slightly alkaline clear watery secretion, containing a peculiar substance called ptyaline along with a trace of albumen; it is under the influence of the facial and the fifth pair of nerves, and when these are excited a corresponding increase of action in the gland is observable. It is essentially an appendix to the function of mastication, and this is probably its only use. There is indeed some discrepancy about its chemical action on starch. Bidder and Schmidt distinctly affirm that it has no action at all upon starch, even after being some hours in contact with it, while, on the other hand, Jacobowitsch maintains the contrary. However, we may safely conclude that at all events the chemical action of the parotid fluid is quite insignificant, and that Bernard is justified in representing it as subserving mastication and that alone. The second source of saliva is the submaxillary glands. The secretion from these is limpid like the parotid fluid, but much more viscid, and becomes gelatinous on cooling; it is also decidedly alkaline, even more so than the secretion of the parotid. Its inorganic constituents are chiefly chlorides, carbonates, and phosphates of lime and soda. According to Bernard the use of this secretion is to assist the functions of taste. The quantity that is poured out by these glands is determined by the greater or lesser degree of sapidity of the food. DIGESTION. 135 Thus he found that when sugar and water was applied to the fauces of a dog, there was hardly any action excited in the submaxilliary glands, but when the gullet was moistened with diluted vinegar or extract of colocynth there was an immediate and copious secretion. In accordance with this view he also found that while the nerves which supply the muscles of mastication on being irritated increased the discharge from the gland of mastication, viz., the parotid, in like manner when the gustatorynerve was excited by galvanism there was an immediate action observable in the submaxillary gland. Their sympathies are with the stomach, for when the secretion of gastric juice takes place it induces an action in the submaxillary glands and not in the others. The submaxillary, (like the parotid fluid,) seems to have a very trifling if any chemical action on the food, for Bidder and Schmidt found that starch remained unchanged when left for some hours in a mixture of the saliva derived from the parotid and submaxillary glands. The third and only remaining gland is the sublingual. The existence of this in the dog and some other animals has been denied by many anatomists, but Bernard contends that this has arisen from an oversight on their part, and that the sublingual glands are always present, and the secretion from them possesses properties wholly different from those of the other two sources of the saliva. The difference consists in the much greater viscidity of the secretion, and its richness in ptyaline, and the traces of sulpho-cyanide of Potassium, which are always to be met with in it. It is, in fact, a sort of mucus, and approaches the true mucus of the buccal 136 DIGESTION. cavity in all its essential characters, and as we shall afterwards see, this mucus performs a most important part in digestion. The distinctive qualities of the three sets of glands are thus, according to Bernard, that the parotid secretion is almost entirely water, and assists deglutition; the submaxillary more viscid and gelatinous on cooling, and is associated with the property of taste; while the sublingual is also very viscid, and does not jelly on cooling, contains much ptyaline, and cooperates with the mucus in its chemical action upon fecula. Bernard relates some curious experiments exhibiting the elective power of the. salivary glands to pass or to refuse various substances carried to them by the blood. He injected into the jugular vein of a dog, 25 grammes of warm water containing 5 grammes of yellow prussiate of potash, 5 grammes of iodide of potassium, and 4 grammes of grape sugar. As soon as the operation was over, he provoked the salivary glands, and on collecting their discharge he found iodine, but not a trace of the prussiate of potash or sugar. After seven minutes, the observation was repeated with the same result. The urine was then examined, and, there, prussiate of potash was found, but neither sugar nor iodine. In twenty-five minutes more they were both examined, and now the urine contained prussiate of potash and a trace of sugar, but no iodine, while the saliva was full of iodine, but without sugar, and prussiate of potash. In three hours the iodine was recognisable in the urine. Thus, the prussiate of potash appeared in seven minutes, the grape sugar in twenty-five to forty, and the prussiate of potash not for three hours. While in the saliva iodine was DIGESTION. 137 found in four hours in its former abundance, but still not a trace of the other two substances which had been injected along with it, and which had both been passed by the kidneys. This experiment, often repeated, never failed to give the same result; and Bernard considers it an established fact, that iodine is at once and constantly discharged by the salivary glands when present in the blood; indeed, its power of passing is so great, that its presence affords an entree to substances, of which iron is one, which without it would be refused admittance into the salivary vessels. This he proved by various ingenious experiments which we have not space to detail, but the result was that while, in general, salts of iron are not to be found in the saliva, although they have been injected into the blood or stomach, yet iodide of iron forms an exception. But a still more remarkable fact, and one of special interest to us, is, that when a solution of two grammes of iodide of potassium were injected into the stomach by an artificial fistula, long after all trace of it had disappeared from the urine, it was still found in the saliva, and in the gastric secretions even after an interval of three weeks. This observation has an important bearing upon the duration of the action of medicinal agents, for its persistence is manifestly due to vital, not chemical laws, and we may now understand the reason of our inability to affect our patients beneficially with our medicines, if they have in their system a poisonous spring, the existence of which we are ignorant. And even if we did know of it, how could we either stop or neutralize this stream of mischief, deranging the healthy actions, and paralysing our remedies? The wonder is, that in the old poisoned patients who come to 138 DIGESTION. us, we can ever do any good at all, and not that we cannot produce, as they expect, immediate and constant improvement! To return from this digression to the action of saliva; it is a well-established fact that the mixed saliva found in the mouth has properties peculiar to itself, and different from any of its constituents. The most probable theory is, that when the secretion from the salivary glands meets the mucus in the mouth, there is then a peculiar action of the nature of fermentation engendered, and that the result of this is to produce a combination which has a very rapid and intense action upon all feculent articles of food. MM. Bidder and Schmidt give a table of the time required to convert starch into sugar in the presence of different secretions, and the chief facts brought out by it are, that this change was instantaneously begun, when saliva from a man, a child of three months old, or a dog was brought in contact with it, while it required twenty minutes to make its appearance when the mucus of the mouth without the secretion of the parotid gland was employed, and one to three hours when the parotid and submaxillary glands were substituted. It seems, then, that neither the buccal mucus, nor the saliva by itself, can do what the two together at once effect. The mixture is required for the ferment. Although it is an established fact that the saliva found in the mouth has a most rapid and energetic action upon the fecula of the food, which it converts, as far as its action goes, into sugar; yet we meet with the singular contradiction of there being no sugar discoverable in the stomach, even although the morsel swallowed be at once removed and examined. The explanations offered of this DIGESTTON. 139 apparent anomaly are not satisfactory; on the one hand it is advanced that the exposure of the feculent materials to the action of the ferment is too short, and that the condition of the starch in the food is not favorable to its being acted on by the saliva; while on the other hand it is supposed that the sugar is either absorbed on its passage to the stomach, or if it reaches that cavity, is immediately converted into lactic acid by the gastric secretions. Such are the explanations; but it is admitted that as yet the difficulties are far from being satisfactorily removed. Thus, at the very outset of the investigation of the process of digestion we encounter an unsolved problem, and we cannot affirm with confidence what chemical changes are undergone by a morsel of bread in its passage from the mouth to the stomach. The existence of sulpho-cyanide of potassium in the saliva is a curious fact that has given rise to much fanciful speculation. It is known that this salt is a powerful poison, and it is conjectured that the poisonous action of the saliva of rabid animals may arise from an increased quantity of this natural ingredient of that secretion. This notion rests on no evidence of any weight, and we may at once dismiss it as wholly insufficient to account for the phenomena of hydrophobia. At the same time it is certainly important to know that this very poisonous substance is liable to be generated in greater quantity by the salivary organs, when a morbid action is developed in them. Thus Lehmann' examined the saliva of a patient suffering from mercurial salivation, and found its properties very different from the normal secretion: it was thick, gelatinous, flocculent, and very 1 Jahibuch dor Phy. Chem.,' B, II. 140 ' DIGESTION. poor in ptyaline; but, on the other hand, contained a large quantity of sulpho-cyanide of potassium. It is certainly not improbable, that some of the noxious effects of this dreadful drug-mercury--may be attributed to its exciting this poisonous secretion, some of which must be swallowed and thus complicate the evils the original poison has inaugurated. Among the other morbid secretions of the mouth, may probably be reckoned the tartar of the teeth. This consists, fundamentally, of phosphates; but although these salts form the basis of the deposit, particles of carbonate of lime, epithelial cells, &c., are mechanically combined with it, and form a notable portion of the whole. The origin of this was supposed to be simply the evaporation of the saliva; but Bernard has advanced the supposition, that it is the result of a slight inflammatory action of the alveolar processes, a chronic periostitis, depending upon irritation of the organs of digestion, and partial denudation of the roots of the teeth. It is more abundant always in the lower than the upper jaw, because the gums are more pressed froi the teeth of the former during mastication; and he found it take place rapidly in dogs, when their digestion was disturbed by a partial closure of the orifice of the gastric fistula, and when the exciting cause was removed, and the normal condition of the digestive functions restored, it as speedily disappeared. This observation has an important practical bearing, and if it is confirmed, the state of the teeth and gums may be found to have a constant relation with certain specific affections of the alimentary canal, and be thus both remediable in themselves, by appropriate medication, and a guide to the prac DIGESTION. 141 titioner in the selection of the remedy proper for the cure of the original malady, on which this lesser one has supervened. Thus the lights of advancing science, which exhibit with increasing clearness, the baleful action of the mercury, the iodine, and the other poisoned arrows which fill the quiver of old physic, are so many safety lamps to us, improving our practice by giving us more exact indications of morbid actions, for the excitement of which, we are not accountable. We have made but small progress as yet, all we have done is the division of the food into smaller parts, its mixture with a watery fluid containing much atmospheric air, and the conversion of a portion of its starch into sugar; in this condition it is projected into the stomach. Here it is exposed to the action of two substances, the one an acid, the other a peculiar principle called pepsine. These two, combined, constitute the gastric juice, and the presence of both is necessary to effect digestion Till of late, our knowledge of the properties of the gastric juice in its physiological relations, were chiefly derived from the experiments of Dr. Beaumont on his patient, who had a fistulous opening in the stomach; but, recently, various experimenters have found that such an opening being easily made in animals, without causing them much inconvenience, they had in their power to repeat and vary these original observations, and have arrived at many more exact conclusions than before were possible. It seems ascer'tained by a great number of experiments, that this gastric juice varies much both in quantity and quality at different times, these variations depend upon the nature of the food received into the 142 142 DIGESTION. stomach; and it is probably owing to this,' that there is so much discrepancy about its chemical composition among the highest authorities. As regards the quantity, Bidder and Schmidt found that a dog of 12 kilogrammnes yielded In -1 an hour 63 grammes, 3 hours after having been fed on meal and water. 1 hour 21.3 with a perfectly empty stomach. 2an hour 33-5 when bones were in. the stomach. 1 hour 62-2 in the same circumstances. il21an hour 120, with a perfectly empty stomach. 1)21an hour 38-0 3 hours after a meal of flesh. So that in four hours this dog, of 12. kilogramines in weight, Yielded 23 grammes of gastric juice. If the human stomach is equally productive, an ordinary sized mian would secrete 6-4 kilogrammes of gastric juice in the twenty- four hours. This estimate is considered very high, but it corresponds with the experiments of Lehmann as to the quantity-of gas 'tric juice required to dissolve albumen. However., as it appears that all the albumen received into the system is not dissolved in the stomach, the correspondence is of less consequence, and when we observe such anl enormous difference in the.yield of different hours, we may well suppose that there is an equal difference in different stomachs, and that be.. fore it is possible to strike an average, it. will require an almost infinite multiplication of observations, It is of more interest to know that there is this difference, and that it is affected by various causes. For example, it was found that the mere sight of a. piece of meat called forth a copious secretion of gastric fluid, after the salivary duct had been obstructed. So that the stomach DIGESTION. 143 as well as the mouth waters at the sight of proper food. Again it was noticed that while this necessary secretion was thus excited by the prospect of eating, an op posite change took place if the animal had been exposed to a painful operation, then the gastric juice lost its digestive power entirely; this, however, was from a change in its quality not its amount. It lost its acidity without which it has no power to perform its office. This was probably owing to the large quantity of saliva which pain often produces: in animals, a sort of weeping from the mouth, and this saliva being alkaline neutralized the acid in the stomach. Thus the operation of sorrow if it gives rise to copious tears may produce a chemical incapacity to digest food, as well as physiological depression of the digestive organs. While it is an undisputed fact that free acid is present in the stomach, and that its presence is an essential condition of the action of the gastric juice upon the aliment, what that free acid is has occasioned much keen controversy. Some, as Prout, Tiedeman, and Gmelin, maintain that it is hydrochloric, while Lehmann and Heintz are of opinion that it is lactic. Sometimes there is free phosphoric acid present, or at least acidity is given by the presence of super-phosphates, but only after the animal has been fed on bones. The result of eighteen analyses made apparently with the greatest possible care has led Bidder and Schmidt to a conclusion which reconciles the conflicting views. They found that in carnivorous animals, after fasting for eighteen or twenty hours, pure hydrochloric acid alone, without a trace of lactic, was present in their stomachs, whereas the stomach 144 DI GESTION. of herbivorous animals contained a certain small and variable amount of lactic acid, which was probably derived from the food. We may assume, then, that the acidity of the gastric fluid in man, if normal, is due to the presence of free hydrochloric acid. Of pepsine little is known chemically; it so far resembles albumen as to be coagulable by heat, and that it is indispensable for the action of the gastric fluid is a certain fact. Neither the acid nor the pepsine suffices alone, for if it be neutralized by carbonate of soda it loses its power, and regains it when the alkali is removed, and equally destructive is the application of heat, which coagulates and destroys the pepsine. The fact of an alkali destroying the effect of the gastric fluid, and instantly arresting its digestive power, explains the mischief bile does when it gets into the stomach. It was found that a very small quantity of bile when mixed with the gastric juice at once and entirely suspended its chemical action upon the substances which it was vigorously handling before the addition. So that after all the phrase in every patient's mouth about being bilious may sometimes have a sounder foundation than we are apt to imagine. Such being the constitution of the secretions from the stomach embraced under the designation of the gastric juice, let us proceed to inquire what is the character of its action upon the three constituents of all digestible food, viz., fat, fecula, and animal or vegetable fibrine. Its only action on the fat is to dissolve the walls of the cells which enclose it, and to liberate their contents; by this, fat is rendered fluid, but undergoes no other change either physical or chemical. DIGESTION. 145 The fecula contained in vegetable cellular tissue, as in a potato for example, is likewise enlarged from its confinement by the solution of the walls of the cells, and is brought into immediate contact with the gastric juice. The only effect of this upon the starch is to produce a hydrate either by its acidity or temperature. This is merely a physical change and not a chemical one, and its reaction with iodine is unaffected by it. Nor are the sugars affected materially, except that cane sugar if long exposed to its action is converted into grape sugar, and this in its turn into lactic acid. However, from the length of time required to effect these transmutations, it is probable that they seldom, if ever, occur in ordinary digestion. Its main work is with the azotized matters. A piece of flesh, for instance, when exposed to the action of the gastric fluid, either in or out of the stomach, is softened and transformed into a grey paste to which the name of chyme has been given. On examining this with the microscope, it is found that the change consists in the separation only of the fibres by the solution of the cellular tissue which bound them together, and that the original structure of the muscle is quite distinguishable, so much so that it is found to be much the best way of procuring the primitive fibres to expose for a length of time a muscular tissue to the action of gastric juice. This separation of the muscular fibre is much more rapid if it have been previously cooked, as was proved by experiments upon dogs. So that, in fact, a great portion of the work of the stomach as regards flesh may be anticipated in the kitchen. Milk and albumen it first coagulates then dissolves; bones it dissolves and removes 10 146 DIGESTION. from them their azotized portion which is very considerable, leaving behind the insoluble earths to be expelled. In this the action of the gastric juice is the converse of acid fluids which dissolve the earths and leave the animal parts of the bone. In all these instances the action of the secretion is strictly physiological, but it has also the power of acting chemically in virtue of its acid nature upon various salts. Considering the wonderful energy with which it attacks and destroys animal tissues, the question natu. rally arises, Why it should not act upon the stomach itself? and the common reply is, that it is owing to the fact of the stomach being endowed with life which in some mysterious way preserves it from this otherwise inevitable suicide. That this is not the true solution of the difficulty is proved by some experiments of Bernard, who introduced portions of live frogs into the stomach of a dog, and found that during the life of the unfortunate victim of science it was partially digested. And the explanation he gives is that the immunity to its own secretions enjoyed by the stomach is due to the epithelial coating which is quite impermeable by the gastric juice, and entirely resists its corroding power, and that it is the absence of such a protecting film in the frog that makes it liable to be digested alive. This theory is probably the true one, and it may serve to explain the curious fact that the poison of the most venomous snakes may be received with impunity in its raw and native state into the stomach, while it produces rapidly fatal effects when injected into the blood. But it would be contrary to all analogy to suppose that because when in its concentrated state it did not act ini the stomach being DIGESTION. 14.7 probably digested and decomposed, that therefore it would not do so when presented to the system in a diluted form, so as to be readily absorbed into the blood, or without this absorption to be brought into direct contact with an extensive surface of the mucous membranes on which nerves are largely distributed. This may reassure us of the probable activity of snake poisons when given as we give them in a highly expanded or diluted state, even in the face of their inactivity, when swallowed in their natural bag, as is done in India. Although it is established beyond a doubt that the gastric juice has the power of dissolving albumen, yet from the experiments of Bidder and Schmidt it appears no less certain that it requires a large quantity of the fluid to dissolve a small portion of the solid, a much larger quantity, in short, than is met with in the stomach. Not only in experiments made with gastric juice taken out of the body, but in all experiments made by dropping portions of coagulated white of egg into the stomach, through an artificial opening, they found without a single exception, that even after six hours, and when there was an excess of gastric fluid present, yet that all the albumen was never dissolved, seldom more than half of it. This startling fact leads to the inevitable conclusion that albumen is only partially digested in the stomach, and we must follow the course of the food down the alimentary canal, before we can account for the digestion even of the albumen, the only one of the three parts of the aliment which undergoes a certain gastric digestion. The pultaceous mass, called chyme, when it leaves the stomach and enters the duodenum, consists of disintegrated food, fecula, free oil, and albumen, in a state of solution, 148 DI GEST'ION. along with fibres of flesh, &c., before it has proceeded far on its downward course, it encounters the secretions of the pancreas and liver, which entirely change its chemical character, and arrest instantly the gastric digestion by throwing down the pepsine, and neutralizing any free acid that may have passed over. The action of the pancreatic fluid has hitherto been regarded as similar to that of saliva, and the pancreas has always been considered as an internal salivary gland, of comparatively little consequence in the process of digestion. Bernard entirely objects to this received opinion, and maintains that the action of the pancreatic fluid is of immense importance. This belief rests upon the following series of facts:1st. The consequences of a destruction of the pancreas in the human body by disease. 2d. Its destruction in animals artificially. 3d. That the changes in the aliment, which he ascribes to the presence of this secretion, do not take place in the duodenum of those animals in which the pancreas discharges itself lower in the intestine until the point where this discharge takes place; and, lastly, upon the experiments he has made upon the action of the pancreatic fluid extracted from animals and brought in contact with the elements of food. In order fully to understand his views it will be necessary to state his experiments, as well as those of Bidder and Schmidt upon the same subject. Unfortunately, the results are in some respects conflicting. The pancreas is an oblong gland, with a duct running from one end to the other in a line with its longest diameter; as this central canal approaches the duodenum, where it debouches, it separates into two branches, the larger of which in man unites with the ductus choledo DIGESTION. 149 chus, while the smaller empties itself separately into the intestines a little higher up. The same disposition of parts is met with in most animals, so that the bile and pancreatic fluid are at once mixed, and operate upon the food in combination with one another. The lesser duct instead of enlarging after its separation becomes smaller, and seems rather to serve the purpose of a reservoir than an outlet; in some animals it has a blind extremity. The position of the pancreas makes it somewhat difficult to perform the operations upon it required for establishing its uses; however, this has been done, and the secretion collected by means of a silver tube connected with an external receptacle. Bernard minutely describes the method he employed. On exposing the pancreas during digestion, it is found red and tumid, and if the duct is opened, the fluid escapes with such rapidity, that a moderate sized dog will yield 5 to 6 grammes in an hour. According to the calculations of Bidder and Schmidt, if the pancreas secretes at the same rate in the human subject as in the dog, a man of average size will elaborate 150 grammes of pancreatic fluid in the course of twenty-four hours. Normal pancreatic secretion is a colourless, limpid, and viscid liquid, which flows slowly in large pearly drops; it has no peculiar taste, but is slightly saline, like the serum of the blood. Its chemical reaction is always alkaline, never either neutral or acid. When exposed to heat it is converted into a solid white mass, possessing many of the properties of albumen. Notwithstanding this similarity there is no identity between the two, according to Bernard; on the contrary, the pancreatic fluid has altogether peculiar properties, as we shall see by and by. In the mean time it is to be 150 DIGESTION. observed that this is true only of the normal pancreatic fluid, for there is an abnormal secretion from the pancreas. The liquid just described is only obtained in general for the first few hours after the operation, then, if the animal exhibits symptoms of inflammatory action, or even great distress, the secretion from the pancreas is wholly changed, and instead of being viscid it becomes watery, and has a nauseous taste; it no longer coagulates with heat and acids, or at least the coagulation is very imperfect. It still exhibits an alkaline reaction, but is of much less density. Bernard considers that it is owing to the morbid secretion being so easily produced in some animals, as the horse, that we meet with so much diversity of statements as to its properties in the writings of different physiologists of equal authority; and he makes a more important observation to the effect that this is one of the distinguishing characteristics of pancreatic fluid from saliva with which it is commonly compared, for while we may take all sorts of liberties with the salivary organs, without affecting the chemical constitution of their secretions, that of the pancreas is, on the other hand, very easily disturbed, and the modifications induced in it by pain or general derangement of the system entirely deprive it of its specific digestive properties. If this view be correct, it is not impossible that some of the forms of indigestion we meet with in practice arise from an organic or functional disease of this organ, and we may, perhaps, be able when we know its functions more exactly, to adjust our remedial measures with more precision and consequently with more success. Without entering minutely into the chemical consti DIGESTION. 151 tution of the pancreatic fluid which is given in great detail by Bidder and Schmidt, we may observe that it consists of from 90 to 92 per cent. of water, and of from 10 to 3 per cent. of solid ingredients; that of the solid part 90 to 92 per cent., consist of an organic matter which may be precipitated by alcohol, and which always contain a little lime, and the remaining 10 or 8 per cent. of that remainder are composed of salts of carbonate of soda, chloride of sodium, chloride of potassium, and phosphate of lime. This coagulable matter holds a middle position between albumen and caseine, possessing certain properties of both, but exactly resembling neither. Upon it the peculiar physiological virtues of the pancreatic fluid depend, for it is abundant or the reverse in direct proportion to the greater or lesser activity of the secretion. It seems to be of the nature of a ferment, and doubtless it is owing to its presence that one of the most marked and important of the functions of the pancreas is due. This function is the transformation of fecula into dextrine and sugar. The change of starch into sugar begins instantaneously when the pancreatic fluid is brought into contact with any amylaceous material, even at a temperature much below that of the living animal. Unlike the saliva which acquires its fermenting power by combining with the secretions of the mouth, the pancreatic fluid possesses the property in its own right. The full extent of its power in this direction has not as yet been accurately determined; it seems, howevec, probable that it is in general sufficient to account for the perfect digestion of the starch contained in the aliment, at least in so far as its conversion into sugar is concerned; and it is of importance to observe that 152 DIGESTION. neither bile nor gastric fluid has any appreciable influence in arresting or modifying in any way this function. Bernard maintains that sugar to be digested must pass through the liver, and hence, that after the conversion of starch into glucose or cane sugar, it is absorbed not by the lacteal vessels but by the vena porta. In confirmation of this view he states, that when 2 or 3 grammes of sugar are injected into a superficial vein, so far is it from being assimilated, that it is actually rejected by means of the kidneys in the course of a few minutes; while, on the other hand, if injected into the vena portae so as to be exposed to the action of the liver, it is perfectly assimilated, and disappears in the blood precisely as if it had undergone the previous gastric digestion. If this idea be true, we can now follow one portion of our original morsel of food from its entrance into the mouth until it is lost in the body. Entering in the form of a piece of bread or potato that is a succulent or starchy substance, it is first rolled about by the tongue, and well mixed by the process of mastication with the saliva and a small portion is converted into sugar, then it descends into the stomach where the sugar is changed into lactic acid; it passes on to the duodenum, where it encounters the pancreatic fluid, which rapidly converts the starch into sugar. This sugar is absorbed by the branches of the vena portae, and carried to the.liver, where it undergoes a sort of ultimate digestion before it is fit to be absorbed into the blood in such a form as to become subject to the action of the atmospheric air upon that fluid in the lungs, where it serves the purpose of fuel, and is, in part at least, consumed to maintain DIGESTION. 158 the vital heat of the frame. What other purposes it serves it would be beyond the scope of our present inquiry to consider. When it has once been assimilated by the blood it has passed from the region of.chemistry into that of vitality, it is no longer aliment, but is become a living element, and not till after it has fulfilled its purpose and is cast out dead will it be subjected to a chemical inquest. While there prevails entire unanimity among physiologists in regard to the transformations of the feculent portions of the food, and the agents by which they are affected, the case is very different with the fat, and on this subject the views of Bernard are novelties well deserving our earnest attention, but which we are hardly yet justified in regarding as established facts. Such as they are we shall state them, waving in the mean time till that is done the objections that have been advanced against them. According to M. Bernard, one of the special functions of the pancreatic secretion, is to assist in the digestion of fat. The property this fluid possesses of transforming all fat and oils into glycerine and elaic, or some cognate acid, does not depend upon its alkaline character, but is an inherent principle, which it derives from its vital constitution; that is, the more pancreatic fluid presents its distinctive animal characteristics, the more rapid and decisive is its action upon oil; and so soon as it begins to assume its thin and watery appearance, it loses some of its decomposing power. If fresh, strong pancreatic fluid, be mixed with half its weight of olive oil, or fresh butter, or mutton suet, or pork fat, a perfect emulsion is formed when the two have been gently shaken toge 154 DIGESTION. ther; and if the vessel in which they have been mixed be kept in a warm temperature, no separation takes place. It is found on examination, that the oils and fats have been decomposed into glycerine and a fat acid. This property of acting with such immediate energy upon oil and fat, is quite peculiar to pancreatic fluid, and is not found in any other secretion of the body. If bile, which is alkaline, be mixed with oil, at first it forms an emulsion similar to what we may call the pancreatic soap; but after having been left at rest for a few minutes, the oil rises to the surface, and the uncongenial union is at once dissolved. It is the same with saliva, gastric fluid, and the serum of the blood, only when saliva is very alkaline it succeeds in effecting a true emulsion with oils, but so soon as the alkali is neutralized by the addition of an acid, it entirely loses this power. This is not the case with the pancreatic fluid, which retains its influence over fat and oil after it has been deprived of its alkaline character by acidulation. The change it works is due to its own specific nature as an animal product, and not to its chemical constitution. Such are the conclusions of M. Bernard, from experiments with pancreatic fluid out of the living body. They are confirmed by the following statements. If, he says, we trace the progress of the oil or fat from its leaving the stomach, we shall find that until it comes in contact with the secretion from the pancreas it has undergone no change, except such as is the effect of the increase of temperature to which it has been exposed; but so soon as it has passed the orifice of the pancreatic duct, it loses all its old properties, and instead of oil, is a pultaceous creamy emulsion coloured with bile. He further states, DIGESTION. 155 that when these ducts are tied, so as to exclude the pancreatic secretion from the intestines, that this emulsion does not take place. It happens that in the rabbit the orifice of the pancreatic duct is placed some inches below that of the biliary duct, and hence it affords an easy mode of verifying the observation, if we ascertain whether or not the transformation of the oil into this emulsion takes place before it descends beyond the pancreatic opening. This seems a point which may be easily and certainly determined. M. Bernard accordingly made the following experiment: he introduced into the stomach of a rabbit which had been fasting for twenty-four or thirty hours, from 1 5 to 20 grammes of pork fat, previously liquefied by a gentle heat, and then gave the animal its natural food of grass and carrots to force the fat down. In three or four hours the rabbit was killed, and the abdomen opened with all possible speed, when it was easily perceived that the formation of the fat into an emulsion, began to take place 35 centimetres below the orifice of the ductus choledichus, at the point where the pancreatic canal entered the intestines, and that not till this point were lacteals full of white chyle to be observed. This seems a most satisfactory observation, but unfortunately we have a counter statement by Messrs. Bidder and Schmidt to the following effect. They, too, gave several rabbits a dose of oil after a fast of twenty-four hours' duration, and killed them at intervals of a diminishing ratio, from six hours and a half to half an hour after, when they found that in the majority of the instances, white milky chyle was to be found in the vessels of the mesentery, above the opening of the pancreatic duct, and they convinced themselves by microscopic ex 156 DIGESTION. amination, that this chyle did really contain oil-globules. In short, the Frenchman and the Germans are at war upon this point, and we must wait for a new peace congress before we can hope for a final settlement. As we cannot admit these experiments on the rabbits to be conclusive either one way or the other, let us consider the other methods of arriving at a knowledge of the functions of the pancreas, pursued by M. Bernard. The chief difficulty encountered by experimenters on this gland, is that its extirpation is attended with such serious injuries, that the operation is generally fatal. I-ence it occurred to M. Bernard to attempt its destruction by means of injecting various substances into its tissue, through the pancreatic duct. After many failures, he succeeded in doing so with oil; a small quantity of this has the effect, when introduced into the substance of the pancreas, of causing its entire disintegration; and when the animal survives the immediate danger of the operation, we have then the interesting experiment of the effects of the withdrawal of the food from the influence of the pancreatic fluid, while it is exposed to all the other ordinary mechanism of digestion. Thus, on an old dog, Bernard performed the experiment with the following results. He injected about four cubic centimetres of mutton suet, liquefied by heat, into the pancreatic duct. On the following day the dog drank a little milk; three days afterwards it ate some flesh; on the seventh day it was not so well, but seemed recovered upon the eleventh day, when the wound was quite cicatrized. On the twelfth day, the dog got a pork chop, and also on the following day. The excrements contained a quantity of oil mixed with fecula; this oil had DIGESTION. 157 not been observed in them before the operation. Next day, again, he was fed on a pork chop mixed with boiled potato, and the same appearances were observed in the stools. The same diet was continued, and with the same results, that is, the stools contained an enormous quantity of oil and undigested starch, which reacted naturally with iodine. The experiment was persevered in for twenty-three days, and although the animal became much emaciated, there was no appearance of any more disturbance of the system than was to be accounted for by its inability to digest so large a portion of its food; and, latterly, the quantity of oil in the faeces diminished. It was killed on the twenty-third day; and on examina.. tion, nothing abnormal was found in the intestines, and the liver appeared healthy. The pancreas was atrophied in a large portion of its extent, but in the centre there was still some which seemed healthy. The ducts were full of the suet which had been injected into them, and which had penetrated the greater part of the substance, and effected this destruction of its tissue, and consequent suppression of its secretion. M. Bernard made several other experiments of a similar kind, and the result was always the same, the destruction of the pancreas caused a large quantity of the fat and of the fecula of the food to appear in the excrements, and hence, the probable inference, that pancreatic fluid is one of the agents by which the absorption or digestion of fat and oil is effected. This view is further supported by the observation of diseases of the pancreas in the human subject. Hitherto, the number of cases of unquestionable alteration of the pancreas verified by post-mortem examination, and manifesting, during the life'of the patient, 158 DIGESTION. inability to assimilate fat, that have been reported in medical literature, is perhaps hardly sufficient to establish so important a dogma. Some, however, are very striking, especially the following one, which rests on the high authority of Dr. Bright. A man of 40 years of age, had long been subject to intestinal haemorrhage, which, latterly, had become very severe, and attended with great sensibility of the epigastrium, alternating with diarrhoea. In the month of December, 1836, after having worked all day in a damp cellar, he was attacked with febrile symptoms and pain, obstinate constipation, followed by diarrhoea. The evacuations contained no bile, but a large quantity of blood, and there was excessive tenderness of the epigastric region. After the lapse of fifteen days, the presence of fatty matter was first observed in the excrements. For some months this appearance continued, the oil passed was in such quantity as to form a thick layer at the surface, which became firm after a time. It had the look of beef fat. The patient affirmed that for six weeks he had observed this fatty deposit to the amount of half a pound a day; but he was positive that it only appeared when he had eaten fat soup or meat. When he discontinued fat diet, the stools no longer presented this appearance, but at once resumed it when he returned to his fat food. Towards the end of August, the existence of a painful tumour was discovered, situated in the epigastric and right hypochondriac region, extending as far as the umbilicus. He died suddenly on the 10th of September. On examining the body after death, a tumour, four inches in length and breadth, was found occupying DIGESTION. the situation of the pancreas, the whole normal structure of which organ had undergone a change, having in fact wholly disappeared, while what remained was shrivelled up, and the whole substance was full of hard concretions. It was manifest that no pancreatic fluid could have been secreted. This is certainly a very remarkable case; but one cannot but regret that we have no mention of the effect of the disease upon the feculent food. Starch, as well as oil, should have been present in the stools, unless the intestines have the power of effecting a modification of these substances without the aid of the pancreas. The following case is reported by Dr. Elliotson. A man of 45 years of age, complained of pain in the abdomen and back, and of diarrhoea. The pains were very violent, indeed intolerable, notwithstanding the administration of opium: he lay doubled up in his bed, as he thought that gave him some relief. The evacuations were pale and covered with a yellow oily substance, which on being brought in contact with the fire burned with a vivid flame. On its first evacuation, this substance was liquid, but it gradually consolidated itself as an envelope round the foeces. Sometimes it appeared in large quantities, at other times it was absent. The patient got very emaciated before his death. On an examination of the body, the intestines presented a yellow oily appearance, with a number of black spots on some parts of their mucous membrane; the liver was healthy, the gall-bladder full of thick dark bile. T/ze pancrealic duct, and its ramifications, were flled with white calcili. The fact of both these cases being quoted by M. Ber 160 DIGESTION. nard and M. Fauconneau Dufresne,' is a sufficient proof that they belong to the curiosities of medical literature; and, however gladly we would accept of this explanation of the functions of the pancreas, we are forced to admit that we are not yet entitled to assume, as an established truth, that the pancreas is necessarily the organ by whose influence the assimilation of fat and oil is effected; although it is highly probable that it exerts some influence upon the process, notwithstanding the emphatic assertion of MM. Bidder and Schmidt, that they consider the Bernard-doctrine of the importance of the pancreatic fluid, in reference to its action upon the absorption of fat, altogether erroneous (in allen Stiicken irrige); and that this secretion has nothing whatever to do with the absorption of fat, and its total sphere of action is the conversion of starch into sugar. When such doctors differ, it would be presumptuous to dogmatise about the doctrine in question, and we must consider the mode in which fat is assimilated as one of the out-standing problems. Bernard maintains that a chemical decomposition is effected by the pancreatic fluid, and that the oil-acid which is this formed, is again neutralized by the free alkali of the bile. He also maintains, that while the sugar produced from the starch and the albumen both pass through the liver, being absorbed directly into the blood of the portal system, the oil and fatty matters pass into the lymphatic vessels, and with the lymph, form the chyle, that they do not pass through the liver, but into the blood as it enters the vena cava; that this is constant throughout the animal king 1 ' Prcis des Maladies du Foie et du Pancreas,' Paris, 1850. DIGESTION. 161 dom, and that those animals in which there is no separate chyliferous system, there is such a distribution of the veins as to allow of a direct communication between those of the mesentery, which receive the oil, and the vena cava, so as to enable the fatty part of the aliment to reach the lungs without making the circuit of the liver. Still the difficulty remains of how globules of oil pass into the lymphatic vessels or the veins, how they penetrate the membranes, which they must do, as there are no open pores, and while doing so, they must apparently violate the well-established laws of endosmotic action; for if an emulsion such as that formed by the pancreatic and bilious fluid, and olive oil, be placed in proximity to a fluid of the consistence of blood, with an intervening animal membrane, it is found that the watery parts of the emulsion are passed through the membrane, and the oil-globules left behind. As we have before observed in speaking of the action of the bile, it seems probable that in some way the secretion facilitates the entrance of the oil. But notwithstanding many ingenious hypotheses, and much careful anatomical research by Professor Goodsir and other accomplished anatomists, the question of how one of the elements of all food enters the system at all, has not yet received a satisfactory answer. This incontestible fact is the keenest satire we could pronounce upon the physiological school of medicine, which professes to be, now-a-days, so perfectly acquainted with the whole mechanism of the living organism, so as to be able to manage it by suitable diet and regimen, and speak of regulating it, as a watchmaker talks about putting a watch to rights. We must remember, too, that in addition to their ignorance of the 11 162 DIGESTION. simple process of digestion, they are equally ignorant of the million influences which modify this, and every other vital phenomenon, forces within and without the body, infinite in number, incessant in their action, and ever varying in their degree. We have now accounted for the fecula and the fat, the conversion of the former into sugar by the saliva and pancreatic fluid, its passage through the liver, and final absorption into the blood; while the fat after being liquefied by the heat of the stomach, and the solution of the cellular tissue in which it is contained by the gastric secretion, is either absorbed by the lacteals, after having been formed into an emulsion by the bile and pancreatic secretion, or is partially decomposed by the latter into an oil acid and glycerine, and in either case is represented by Bernard to pass into the venous system directly without passing through the liver, and all that remains to do is to account for the large residue of the albumen which escapes the action of the gastric fluids and passes into the intestines in its original condition. The digestion of the remaining albumen seems to take place in the intestines. This fact is established by a series of experiments made by MM. Bidder and Schmidt. These bold and indefatigable physiologists performed the following operations on nineteen cats and two dogs. They opened the abdominal cavity, exposed the duodenum and jejunum, tied a ligature below the orifice of the biliary and pancreatic ducts, and another some distance lower down; they then introduced into the intestine as high up as possible a piece of flesh and a portion of coagulated albumen, which they had previously carefully weighed, they closed the opening of the parietes with a DIGESTION. 163 -ligature and let the animal go. The effect of this apparently most severe operation was very different in different individuals, some were quite exhausted by it, but others did not seem to have suffered at all, and went about as if nothing had happened. In the course of from four to six hours the portions of meat and albumen were generally advanced a considerable way in the intestines, and in every instance they had lost a considerable proportion of their original weight. To avoid any error from mechanical abrasure of their surface, they had been previously enveloped in a piece of lace or muslin, and as the experiments were all made after the animals had been fasting for at least twenty-four hours, there could be very little secretion from the stomach, liver, or pancreas present in the intestines. Hence, we are conducted to the inevitable inference that the secretion from the surface of the intestines acts as a solvent upon the albuminous portion of the food, and that the digestion of this element of diet begins in the stomach and continues through a portion at least of the alimentary canal. The important action of this secretion is not confined to its effect upon albumen, for it appears to have the power of transforming starch into sugar, although it certainly does not do so with so much rapidity as either the mixed saliva or the pancreatic fluid. Still it was observed that whether when removed from the body or in situ, when an amylaceous preparation was brought in contact with the intestinal secretion, a change was speedily observed in the tint of the blue it struck with iodine which was sensibly paler, while on the other hand the tests for sugar revealed the existence of that substance. Thus we perceive that the feculent element of diet is the 164 DIGESTION. one most acted on, its chemical transmutation commencing the instant it enters the mouth, and continuing during its whole course through the alimentary canal, and in this progress it is subjected to the influence of agents which all effect its transformation into some form of sugar, which in its turn is capable of being absorbed by the veins it encounters in every portion of its course. We are now approaching the termination of our immediate object-a review of the recent investigations connected with digestion-and it is certainly disheartening to consider how few and meager are the results of so much labour expended by men of so much knowledge and ability; it would seem that they have unsettled everything and settled nothing; the old established notions on which the chemical school have built so many imposing fabrics, with Liebig for master-mason, are found to be a shifting sand instead of a sure rock; it is now quite certain that the animal organism possesses a chemical power of transmuting proximate principles; it is not true that the sugar, the fat, and the albumen are only absorbed from the food which must contain them if they pass thence into the living body; on the contrary, we nowknowthat albumen is changed into sugar, and there is good reason for believing that a much larger quantity of fat is found in the body than entered the stomach, and most remarkable of all is the fact stated by Bernard that if albumen from the blood, or white of eggs be injected into the veins, it is not invested by the body, but passed off by the kidneys to the detriment of the health of the animal. It would seem that a special elaboration of the aliment was required for the specific requirements of every individual, and that one man DIGESTION. 165 could never digest for another, if the term digestion is to mean not merely the cooking of the food in the stomach and intestines, that is dissolution, but its preparation into such a condition as to be appropriated by the body for its own reconstruction. The new observations and conclusions are but the beginning of many that we may expect to follow, and, in the mean time, these will be a warning to us how we venture to dogmatize upon the subject of diet, for until we possess some certain knowledge what the body can make of its food, all reasonings upon the subject are likely to be fallacious. For example, it is positively affirmed that alcoholic liquids are innutritious, but can we be sure that alcohol may not be decomposed by the liver and converted into sugar or fat? Certainly, a few years ago, if any one had asserted the transformation of albumen into sugar, he would at once have been mobbed by the chemists, and yet the chemical constitution of sugar is farther removed from that of albumen than alcohol is from fat. The practical inferences to be derived from a general survey of the established facts and suggestions contained in the works of the physiologists are so clear that we do not need to prolong this paper by lingering over them. It is sufficiently obvious that, if under the name digestion we embrace the total transformations that the aliment undergoes from the crude material that enters the mouth to the matters which are received into the blood to constitute the vital fluid, which penetrates all the organs, and affords to each its proper nourishment, and the elements out of which to fabricate its peculiar secretions, the process is a very long and complex one, 166 DIGESTION. and that its abnormal states, known by the general term of indigestion or dyspepsia, may arise at any one of its many stages. It may begin at the mouth, there may be insufficient mastication and insalivation; it may be in the stomach, from a want of proper gastric fluid; it may be the pancreatic secretion that fails, or the liver may not perform its important and numerous functions satisfactorily; and, lastly, it may be that the membrane of the intestinal tube is incapable of performing its portion of the joint labour. Now it is obviously essential to a radical and rational system of medication that we should if possible ascertain the exact source of the disorder in any individual case of indigestion, and we may be able to do so better if we attend to the conclusions afforded by these investigations. Not only, however, will this careful application of physiological inferences enable us to attain greater exactitude in diagnosis and consequent selection of a specific remedy, but it will also assist us to some extent, at least, in a judicious arrangement of the diet. We observe, for example, that albuminous food, besides undergoing a gastric digestion, is dissolved and absorbed by the jejunum, and hence it follows that even when we know the gastric functions are too weak to perform the necessary changes upon animal food, we may give an ample supply of this nourishment to the body in the form of soup, in fact almost the whole of the work of the stomach may be imitated in a. stew-pan. As for the feculent principles, we have seen that there is no portion of their course from the mouth to their final disappearance, in which they are not exposed to the transforming process which makes them into a sugary compound capable of absorption except during their so DIGESTION. 167 journ in the stomach. While fat and oils require for their admission conditions of which we are as yet very ignorant, but if the view of Bernard be correct, perhaps in cases where there is a manifest difficulty of digesting these in any of their natural forms, a substitute might be found in glycerine1 or in some preparation of this substance. We are evidently on the threshold of many important discoveries in connection with the great practical question of how best to feed our patients, and we cannot but anticipate rapid progress in this direction now that the fact is beginning to be acknowledged by the advanced school of medical naturalists that the less the ailing body is tormented with drugs, and the more it is helped by a nice selection of proper food, the sooner and the safer will its health and strength be restored. The rude empiricism, that destroys the vital powers and perverts their functions in the wild hope that out of a general perversion and anarchy a conversion to order will eventuate, is rapidly passing away, and when a rational system of management by diet and regimen has been once fairly introduced, and its deficiencies made manifest, we may hope that the way will be prepared for the admission of a rational system of medication founded upon the great truths promulgated by Hahnemann. Dr. Chapman has recently directed the attention of the profession to the importance of glycerine as an article of diet. CHAPTER V. ON THE WATER-CURE. THERE is a vague idea in the minds of many, that there is some near relationship between homceopathy and the water-cure or hydropathy. This seems an erroneous opinion; for if we carefully analyse the two systems we shall find that they do not spring from the same root, but are radically different. Indeed the water-cure is in its theory much more nearly allied to the allopathic than to the homceopathic system. It seeks to accomplish, by the use of water, the same kind of effects which the old school attempts to gain by drugs: that is, to produce certain general commotions of the animal economy, which shall result in the restoration to health: and the only distinction between the two-a very important one it is-consists in the fact, that the substance employed is not of a noxious character, and that measures are taken for securing the best possible conditions to promote recovery, during the period the body is put through its purgation. The water-cure may be considered as a sort of rectified spirit of old physic, a distillation which separates the grosser and offensive parts from the pure, simple, and limpid: the residue being those impurities which medicine has contracted throughout its descent from the primitive age of WAT'lR-C UE. 169 Hippocrates; and this spirit being a restoration of the fine natural system which was taught and practised by the priests of Hygaea. It might be called a quantitive method in opposition to homoeopathy, which is a qualitative system. For while the one alters the distributions of the fluids and induces changes in the mass of the solids, the other acts upon the seat of the morbid changes alone, and affects only the quality of the action in these parts. Such being, as it seems to us, the undeniable and irreconcilable difference between the two systems, it becomes a question for those who avow their general adherence to homoeopathy, how far they can avail themselves of the other method: and this is one of those pressing questions which every practitioner must be prepared to answer as it were on the spot; for the growing popularity of the water-cure, and the confidence which so many have in its efficacy, exposes the physician continually to interrogations from his patients, as to whether such and such a case be a fit one for water treatment, and whether he can recommend that it should be tried, or whether he is prepared to apply himself any of their celebrated processes. To be able to give a satisfactory reply, he must first make up his mind on the general question, of how far he is entitled, and if entitled, we might almost say bound, to employ certain auxiliaries in addition to administering the appropriate medicine; if this question is answered in the affirmative, as it has been by the common sense of Britain, then he will have to inquire whether there are any appliances used by the practitioners of the water-cure which he may adopt without so disturbing the system of the patient as to prevent it 170 WATER-CURE. from obeying the specific antidote to his disorder; and also whether there is a class of cases for which the watercure is better adapted than homoeopathy, and how he is to recognise this class, so that when a patient belonging to it seeks his advice, he may be prepared to say, "this is not a case for me to treat, you must go to a watercure establishment." My belief, founded upon considerable observation and the perusal of the scanty literature of the subject, is, that there is an exceptional, although numerous class of invalids whose complaints will altogether defy the best and most patient homoeopathic treatment, and who will rapidly improve under a course of water-treatment, and also that there are several of the applications of water which might be advantageously employed as auxiliaries to homoeopathic treatment. In enumerating the cases in which water-treatment seems to me unquestionably advantageous, I should not wish to be understood to limit its applicability to those cases alone, for I do not profess to have made sufficient study of the subject to attempt to fix its limits; all I am prepared to do is to point out some few well-marked maladies, for which I have reason to believe this system is certainly suited, and in which, as far as my own experience has gone, I have had but unsatisfactory results from unaided homoeopathy. The first case I select for illustrating this position, is one to which the objection may arise, whether recovery could not have been effected under homoeopathic treatment. My belief is that it might, but that it would certainly have been a very tedious cure, and that it was such a case as we should be in no way particularly ambitious of staking the credit of homoeopathy upon. It WATER-CURE. 171 is related by the distinguished patient himself, Sir E. Bulwer Lytton, and done so pleasantly and well that, although somewhat long, it well repays perusal. "I have been a workman in my day," he says; "I began to write and to toil, and to win some kind of a name, which I had the ambition to improve when yet little more than a boy. With strong love for study in books-with yet greater desire to accomplish myself in the knowledge of men, for sixteen years, I can conceive no life to have been filled with more occupation than mine. What time was not given to action was given to study; what time not given to study, to action-labour in both! In a constitution naturally far from strong I allowed no pause or respite. The wear and tear went on without intermission-the whirl of the wheel never ceased. Sometimes, indeed, thoroughly overpowered and exhausted, I sought for escape. The physicians said 'travel,' and I travelled; 'go into the country,' and I went. But in such attempts at repose all my ailments gathered round me -made themselves far more palpable and felt. I had no resource but to fly from myself, to fly into the other world of books, on thought, or reverie-to live in some state of being less painful than my own. As long as I was always at work it seemed that I had no leisure to be ill. Quiet was my hell. At length the frame thus long neglected, patched up for awhile by drugs and doctorsput off and trifled with as an intrusive dun-like a dun who is in his rights, brought in its arrears, crushing and terribly accumulated through long years, worn out and wasted, the constitution seemed wholly inadequate to meet the demand. The exhaustion of toil and study had been completed by great anxiety and grief. I had 172 WATER-CURE. watched with alternate hope and fear the mournful death-bed of my dearest friend-of the person around whom was entwined the strongest affection my life had known-and when all was over I seemed scarcely to live myself. At this time, about the January of 1844, I was thoroughly shattered: the least attempt at exercise exhausted me; the nerves gave way at the most ordinary excitement; a chronic irritation of that vast surface we call the mucous membrane, which had defied for years all medical skill, rendered me continually liable to acute attacks, which, from their repetition and the increased feebleness of my frame, might at any time be fatal. Though free from any organic disease of the heart, its action was morbidly restless and painful. My sleep was without refreshment; at morning I arose more weary than I had lain down to rest. * * * I resolutely put away books and study, sought the airs which the physicians esteemed most healthful, and adopted the strict regimen, on which all the children of _Esculapius so wisely insist. In short, I maintained the same general habit as to hours, diet (with the exception of wine, which in moderate quantities seemed to me indispensable), and so far as my strength would allow of exercise, as I found afterwards instituted at hydropathic establishments. I dwell on this to forestall in some manner the common remark of persons not well acquainted with the medical agencies of water-that it is to the regular life which water-patients lead, and not to the element itself, that they owe their recovery. Nevertheless, I found that all these changes, however salutary in theory, produced little practical amelioration in my health. All invalids know, perhaps, how difficult in ordinary circumstances is the WATER-CURE. 178 alteration of habits from bad to good; the early rising, the walk before breakfast, so delicious in the feelings of freshness and vigour, which they bestow upon the strong, often become punishments to the valetudinarian. Headache, languor, a sense of weariness over the eyes, a sinking of the whole system towards noon, which seemed imperiously to demand the dangerous aid of stimulants, were all that I obtained by the morning breeze and the languid stroll by the sea-shore. The suspension from study only affected me with intollerable ennui and added to the profound dejection of the spirits. The brain, so long accustomed to morbid activity, was but withdrawn from its usual occupation to invent horrors and chimeras. Over the pillow, vainly sought two hours before midnight-, hovered no golden sleep. The absence of excitement however unhealthy only aggravated the symptoms of ill health." In this condition he went to Dr. Wilson's establishment at Malvern. The results of his experience are thus detailed. " The first point which impressed and struck me was the extreme and utter innocence of the water-cure in skilful hands-in any hands indeed not thoroughly new to the system. Certainly when I went I believed it to be a kill or cure system. I fancied it must be a very violent remedy-that it doubtless might effect magical cures, but that if it failed it might be fatal. Now I speak not only of my own case but of the immense number of cases I have seen-patients of all ages- all species and genera of disease-all kinds of conditions of constitutions when I declare, upon my honour, that I never witnessed one dangerous symptom produced by the water-cure, whether at Dr. Wilson's or the other hydropathic esta 174, WATER-CURE. blishments which I afterwards visited. * * * The next thing that struck me was the extraordinary ease with which good habits are acquired and bad habits relinquished. The difficulty with which under orthodox medical treatment stimulants are abandoned is here not witnessed. Patients accustomed for half a century to live hard and high, wine-drinkers, spirit-bibbers, whom the regular physician has sought in vain to reduce to a daily pint of sherry, here voluntarily resign all strong potations, after a day or two cease to feel the want of them, and reconcile themselves to water as if they had drank nothing else all their lives. Others who have had recourse for years and years to medicine, their potion in the morning, their cordial at noon, their pill before dinner, their narcotic at bedtime, cease to require these aids to life as if by a charm. Nor this alone. Those to whom mental labour has been a necessary, who have existed in the excitement and stir of the intellect, who have felt, these withdrawn, the prostration of the whole system, the lock to the wheel of the entire machine, return at once to the careless spirits of the boy in his first holiday. Here lies a great secret; water thus skilfully administered is in itself a wonderful excitant, it supplies the place of all others-it operates powerfully and rapidly upon the nerves, sometimes to calm them, sometimes to irritate, but always to occupy. Hence follows a consequence, which all patients have remarked, the complete repose of the passions during the early stages of the cure; they seem laid asleep as if by enchantment. The intellect shares the same rest; after a short time mental exertion becomes impossible, even the memory grows far less tenacious, of its painful impressions, cares and griefs are WATER-CURE. 175 forgotten; the sense of the present absorbs the past and the future; there is a certain freshness and youth which pervade the spirits and live upon the enjoyment of the actual hour. Thus the great agents of our mortal wear and tear, the passions and the mind, calmed into strange rest-nature seems to leave the body to its instinctive tendency, which is always towards recovery. All that instructs and amuses is of a healthful character. Exercise, instead of being an unwilling drudgery, becomes the inevitable impulse of the frame braced and invigorated by the element. A series of reactions is always going onthe willing exercise produces refreshing rest. The extraordinary effect which water taken early in the morning produces on the appetite is well known amongst those who have tried it even before the water-cure was thought of; an appetite it should be the care of the skilful doctor to check into moderate gratification: the powers of nutrition become singularly strengthened, the blood grows rich and pure-the constitution is not only amended, it undergoes a change. The safety of the system then struck me first; its power of replacing by healthful stimulants the morbid ones it withdrew, whether physical or moral, surprised me next; that which thirdly impressed me was no less contrary to all my preconceived notions. I had fancied that, whether good or bad, the system must be one of great hardship, extremely repugnant and disagreeable. I wondered at myself to find how soon it became associated with pleasurable and grateful feelings, as to dwell upon the mind amongst the happiest passages of existence. For my own part, despite of all my ailments, or whatever may have been my cares, I have ever found exquisite pleasure in the sense of bein1, which is 176 WATER-CURE. as it were the conscience, the mirror of the soul. I have known hours of as much and as vivid happiness as can fall to the lot of man, and amongst all my brilliant recollections I can recall no periods of enjoyment at once more hilarious and serene than the hours spent on the lovely hills of Malvern, none in which Nature was so thoroughly possessed and appreciated. The rise from a sleep sound as childhood's, the impatient rush into the open air, while the sun was fresh and the birds first sang, -the sense of an unwonted strength in every limb and nerve, which made so light the steep ascent to the holy spring,-the delicious sparkle of that morning draught,the green terrace on the brow of the mountain, with the rich landscape wide and far below,-the breeze that once would have been so keen and biting, now but exhilarating the blood and lifting the spirits into a religious joy; and this keen sentiment of present pleasure, seconded by a hope sanctioned by all I felt in myself and nearly all I witnessed in others, that that very present was but the step-the threshold into an unknown and delightful region of health and vigour-a disease and a care dropping from the frame and the heart at every stride."' The upshot of the whole trial was restoration to health. Now we think all our readers will agree with us that Sir Edward did well to go to Malvern; that had he staid in London, even in the hands of the most skilful homoeopathic physicians, he would not have recovered so rapidly ' Confessions of a Water-patient, in Colbourn's New Monthly Magazine. Sept., 1845. Although we have reason to believe that there is a good deal of exaggeration in all this, and that if Sir E. B. Lytton were to write the account now that he would tone it down considerably, yet we think it is instructive as showing the state of excitement and exhilaration produced by the water-cure on a sensitive nature. WATER-CURE. 177 or so pleasantly. It was "tute cito etjucunde." And the case is especially interesting as illustrating the immediately anodyne influence of the water treatment upon the brain and whole nervous system. This observation I have had frequent opportunities of making; and those who have felt the importance of having some safe anodyne at their command in the treatment of the disorders of the cerebral and nervous systems will fully appreciate the importance of this discovery. We think it fortunate for science that so skilful a painter as Sir E. Lytton Bulwer has given us two such pictures as those here presented, the one of his feelings before, the other after his water-cure. Nor do we regret the omission of all details of his treatment, the important point for us practically is that it was effected at a water-establishment, and that it required all the accessories of such an institution, including mountain air, fine scenery, good weather, to effect the result. The next case we shall quote presents interesting features both of resemblance and of contrast; it is related by Dr. Gully. "For several years, a lady of 48 years of age, had been subject to most distressing and alarming head symptoms; intense prostrations; headaches; giddiness, that caused her to reel; bursting sensation of the skull; violent irritating pains constantly in the head. To these were added great nervousness; bound bowels; scanty urine; constant feverishness; vehement flushings of the face, and cold feet. The pulse was large, but yielding and most irregular; appetite small; sleep very much disturbed. She had undergone violent medication at the hands of the first provincial and metropolitan autho12 178 WATER-CURE. rities, whose object appears to have been to derive powerfully from the head by such remedies as five grains of Calomel at night, with some drastic draught in the morning; whilst little attention seems to- have been given to the diet. However, between the original malady and the excessive irritation set up by the medicinal treatment, the nerves, both ganglionic and cerebral, and their centres were in the most alarming condition." The treatment was the following:" August lst.-Hot fomentations to the abdomen for an hour at bedtime. The flannels changed every ten minutes, and a wine-glassful of cold water drunk at each change. Damp compress on the bowels to be worn night and day. From three to four tumblers of cold water to be taken during the day, to be taken in small quantities at a time. Breakfast of cold toast and a little butter-no liquid whatever. For dinner, three ounces of animal food-mutton, beef, poultry, or game, three times a week, with as little liquid as possible. On other days the dinner to consist of a cup of cocoa, with cold toast and butter, or of some farinaceous pudding eaten nearly cold, very weak and almost cold tea. The pulse becoming less hard and bounding; after this I proceeded with more decided treatment. " 4th.-Packed in wet sheet for an hour before breakfast. Dripping sheet after it. All the rest as before. "c 5th.-The same, except that the shallow bath was used instead of the dripping-sheet after the packing. The patient remained four minutes in it, was well rubbed, and had water repeatedly poured over her head. WATER-CURE. 179 " 9th.-Sitz-bath, at 700, for a quarter of an hour at noon, was added to the above. Did not agree; headache came on an hour or two afterwards. "12th.-Packing and shallow bath before breakfast; a foot-bath of cold water, with some mustard flour in it, for ten minutes, twice in the day; fomentations at night; abdominal compress, three to four tumblers of water. This was the treatment up to the 10th. " 27th.-The head suffering a good deal, ordered footbath of mustard and water; also that the nape of the neck should be rubbed for fifteen minutes with the same mixture. Head immediately relieved. This instead of the packing. " 28th.-Packing as usual, then footh-baths in the course of the day. " September 2d.-Pulse considerably reduced by the long-continued packing, fomentations, &c. Somewhat inclined to hysterics too; nervous headache. All these signs indicating that the lowering process had been carried as far, or at least as fast, as the system could bear. Therefore, on the " 3d.-I only ordered the cold shallow bath before breakfast, and the foot-baths as usual. " 4th.-Shallow-bath on rising; foot-baths as usual; sitz-bath at noon for half-an-hour. Rode out in a wheelchair at two o'clock for half-an-hour; came home and vomited copiously until five o'clock. Here was the beginning of an internal crisis which the packing fomenta. tions, &c., by removing the irritative state of the internal organs, had enabled them to effect. The nervous condition of the second was the symptom of the commencing effort which terminated in this manner. The matter 180 WATER-CURE. vomited consisted of clear, frothy mucus, mixed with a black, tenacious, heavy substance. A cold sitz-bath for quarter of an hour after it, and fomentations at night, removed all traces of the emetic tumult. " 5th.-Shallow-bath in the morning; foot and handbaths three times in the day; sitz-bath for half-an-hour at noon, and a quarter of an hour at five p.m. Discharge of blood from the bowels in the morning. Another character of the internal crisis; head altogether free from pain; and she said she felt lighter and better than she had ever done. " 6th.-Treatment as above. Fomentations at bedtime; walked more than a mile steadily; much better to-day. In the course of the night colicky pains, followed by free diarrhoea, the bowels acting twice. " 7th.-Treatment the same. Walked and then drove out for an hour. Felt better than she had done from the beginning. " 8th.-Nothing but the shallow-bath. But as she became languid from going to church she took a footbath, which soon restored her. Quite well in other respects. " 10th.- Some little feverish disturbance induced me to order a packing to-day. Foot, hand, and sitz-baths as before. * Head became bad from too long a drive. Fomentations at bedtime. "l lth.-After a good night felt well; ordered footbaths. Suddenly seized with copious vomiting and purging. Took sitz-bath after them, and went out quite well. " 13th.-Walked out twice and drove once; packed in the morning in wet sheet. Two sitz and two foot WATER-CURE. 181 baths, and several hand-baths in the day. A considerable quantity of blood passed from the bowels. " 15th.-Sick again. " 19th.-Head from the last week perfectly well, and admitting of a good amount of exercise. This day, however, she overdid it, and the head became bad in the night. Had not packed for three days; but on account of the increased headache she, on the "20th-Packed; did not walk out at all, took one foot and one sitz-bath and a drive. " From this time to the 24th.-When the patient left Malvern she continued to take shallow-bath in the morning, two foot-baths, and two hand-baths. Throughout the latter month of the treatment, the vomiting and purging, with occasional discharge of blood from the bowels, continued in various degrees; but I have only noted the days when either of these were excessive. Fomentations were frequently employed at night for twenty or thirty minutes, according to the transitory condition of the head; when it was worse, with increased strength of pulse, they were used; when it was bad without that sign, additional foot-baths and sitzbaths were beneficially taken. This lady left Malvern on the 20th of September, taking with her the following directions, to be pursued at home. "Shallow-bath, at 580, every morning for two minutes. " Two foot-baths, of ten minutes each, in the course of the day. "A sitz-bath at 650 for half-an-hour every other day at noon, or at any time three hours after a meal. "Wear the compress all day. 182 WATER-CURE. " It would be well to pack in the wet sheet once a week or so, with the shallow-bath as above; but if all is right in the head and bowels; that is, if the head is free from heat and pain, and the bowels sufficiently open, omit this. "Vegetable diet, except three times a week, when animal food may be taken at dinner. "The deafness with which the patient was affected varied in the course of her treatment at Malvern, but on the whole diminished so much, that by the time she left she could hear perfectly well, if too many voices were not crossing each other at once. Perseverance in the above directions at home completely relieved it. "It should be recalled that previously to trying the water treatment this lady, whose position in society is high, had been rendered incapable of entering it; the excitement of the smallest ' reunion' was too much for her heart: besides which, the headaches were so frequent and so intense, that she could form no engagement with the smallest certainty of being able to fulfil it; whilst her increasing deafness was daily rendering society impossible and distasteful to her. Neither could she find pleasure in travelling; for ten or twelve miles in the easiest carriage was more than she could bear in one day. But after going through the above treatment all was changed. Her headaches had gone-gone so far that between September, 1844, when she left Malvern, and May, 1845, when she returned, she had not more than three attacks for a few hours (induced by mental excitement), and of a vastly mitigated character, instead of one or two bad attacks every week, and more or less of it every day. The restoration of her hearing was her WATER-CURE. 188 restoration to society. And the certainty she had, that at any time when the head had been tried by talking or listening, she could put herself to rights with a wet sheet and a foot-bath, rendered the life worth possessing which had been for a long time previously intolerable. In this altered state of circumstances she passed through the winter of 1844-45. In the month of May of the last year a considerable amount of mental excitement, experienced whilst undergoing the physical excitement of travelling from place to place, added to irregularities of times of eating inseparable therefrom, brought back some of her ailments; that is to say, some degree of flushing, and a considerable degree of deafness; in all other respects she remained well, showing the partial character of the mischief. Still the causes had been reapplied, and the effects were inevitable; and I therefore recommended her return to Malvern for a short course of more active treatment. Into this I need not enter; it was as nearly as possible the same as on the former occasion, allowance being made for the safer condition of the brain, and the consequent possibility of carrying on the treatment more fully at once. Assiduous wet sheet packing and fomentations soon brought on the vomiting and diarrhcea crisis as before; the deafness disappeared still more suddenly than on the previous year; and in every other particular her state has been one of health since. Constantly taking medicine for years she has not taken one drop or grain of any sort of physic from the time she came under my care nearly eighteen months ago. Undoubtedly, being of an excitable and anxious nature, she will be obliged to minager her nervous system. However, she is able to visit and receive 184 WATER-CURE. company; she enjoys life, and is free from all chance of apoplexy; none of which points she could attain under the medicinal plan of treatment to which she had been so long subjected, but the enjoyment of which she now owes to the water-cure. It is very satisfactory to be able to add to this case the following letter I received from the husband of the patient, in January of the year 1847;-' I am truly happy, at the commencement of the present year, to be able to tell you, that during the space of the last eighteen months, my wife has been in the enjoyment of good health, thanks to your kind and judicious treatment by your excellent hydropathic system. She has been seventeen years married, during which time I never knew her to be even tolerably well, and latterly she had been getting worse and worse, with constant pains in her head, tormenting her by day, and depriving her of her rest by night. At whatever place we visited we were obliged to call in medical advice; and I may say that she had the first, in and out of London, that could be obtained. Some of them attributed her complaint to one thing, some to another. There was no end to the application of leeches and blisters, and her inside was literally inundated by a variety of medicines, till she was visibly about to sink under her complaint. When I took her to Malvern, such was her distressing state that, though the distance from my home is only thirty-five miles, we were obliged to stop a night on the road. A two months' residence at Malvern, under your care, worked wonders, and now enables me to say that she has been ever since, and still continues, perfectly well, is quite free from all pain, and is able to eat, drink, and sleep, as well as any one could WATER-CURE. 185 " desire; and our neighbours who know her former state look at her with perfect astonishment. From the time she first commenced your treatment to the present she had not had recourse to any medicines or professional assistance whatever," &c. &c. " One of the accusations against the water treatment is, that it is apt to produce fulness of blood in the head and apoplexy. This is said by persons who have no experience whatever of it, who have never seen a single case of any sort treated by it. I, who have treated disease in no other way for the last six years and a half, find a very different result of large experience, and were the choice given me of diseased conditions, wherein I could produce the most certain and satisfactory effects, and show in the clearest manner the safety and speedy efficiency of the treatment, I should, beyond all comparison of cases, choose one of apoplectic fulness."1 We have selected this somewhat long case for quotation for various reasons. We cannot but regard it as one of unequivocal cure by water treatment, not merely of recovery during the process, the length of the previous illness, the immediate relief afforded, the ultimate completeness of the restoration of health entitle it to rank as a cure. It is besides a very characteristic cure; it was attended by those wonderful crises which remind one of the medicine of the ancients, the improvement so frequently corresponded with a crisis as to leave no doubt in the mind of Dr. Gully that the two stood to one another in the relation of cause and effect. It would lead to too long a digression to enter into a full discus1 'The Water-Cure in Chronic Diseases,' by James Manby Gully, M.D., &c., &c., 4th edition, London, 1851, pp. 220, et seq. 186 WATER-CURE. sion of these critical discharges, but there are some practical inferences from their occurrence, it would be well to bear in mind. Without venturing to assert that, in every case, these violent perturbations of the system are the result of setting loose the drugs which have been previously taken, we cannot but think it is not improbable that such may be the case; for in the course of treatment the perspiration is described as becoming impregnated with the most disagreeable odours, and in some cases gamboge and other drugs are distinctly recognised. Now, it is hardly possible that when such drugs are dissolved by the water imbibed into the system, and enter into the circulation, as they must do before they are thrown off by the cutaneous secretion, that they should not display some of their characteristic effects on the system; so that the copious draughts of water and the solicitation of the augmented mass of fluid in the body to the skin, forcing it in this way, to permeate a great extent of capillary circulation, must have the same effect as injecting into the blood a solution of various medicinal substances, diluted by a large quantity of water. In this respect, indeed, the water-drinking and sweating process resembles the trituration of our inert mineral medicines, by which their activity is brought into play. Whether this hypothesis of the cause of these profuse, so called critical discharges, be admitted or not, we think it is quite manifest, that during such a process of severe handling, it would be absurd to expect any action from homoeopathic medication. In fact, the conditions for homceopathy do not exist. The symptoms most prominent are not those of the disease, but those of the treatment; and it would be as reasonable to 187 WATER-CURE. attempt to treat homceopathically a patient under the action of the waters of Cheltenham as those of Malvern; that is, to attempt to unite the two systems in effecting a radical cure; for as we shall afterwards see, that watertreatment may be a good auxiliary to homceopathy; so here, while the main treatment is by the power of water, yet the transitory annoyances which attend this process may be removed or alleviated by specific medicine; so that while the water is effecting a radical reformation in the constitution, homoeopathic medicine may prevent many of the inconveniences which would otherwise attend such a rude mode of cure. We are then brought to the conclusion that there are cases better suited for the watercure than for homoeopathy, and that in these homceopathic medicine must play a quite subordinate part. We shall find as we proceed that this class is small and quite peculiar; and it is, of course, as much our duty to discover and define the maladies which are thus curable as it is to be prepared with the specific medicines for those which we treat homceopathically. My present opinion, formed after some months' residence at Malvern, in constant intercourse with patients who had been, or still were, undergoing the water-cure, and the careful perusal of the best authenticated cases is, that the only kind of affections in the treatment of which this method is unequivocally superior to any other, is the class represented by the two examples which I have cited, and which are both very well described, although from different points of view. It would be difficult to designate them by any pathological denomination; but they must be quite familiar to all who have had considerable practice in any large town, more 188 WATER-CURE. especially if the kind of pursuits most followed there, involve severe and continued mental exercise or excitement; and on looking back upon my own experience, I could at once point out several similar cases which held out against all homceopathic medicines, and could not be entirely reduced, although considerably mitigated in severity. In limiting thus the efficiency of the watercure, as compared to homceopathy, I should not wish to be understood as rejecting the numerous cases which are related as having been accomplished by it, more especially those of diseases of the stomach and the other digestive apparatus, admirably described in Dr. Gully's work. All I mean is, that there would be no difficulty in finding parallel cases in the practice of every homceopathic physician; and while it may be in many instances the wisest and pleasantest thing a dyspeptic can do to pay a visit for six weeks to a good water-cure establishment, yet I do not consider that it is the duty of a homoeopathic physician to recommend the step at once, unless the case be quite an exceptional one; whereas I do think that it is the duty of every physician to advise a person in the condition Sir E. Lytton Bulwer described himself to be in, rather to try the effects of the watercure than to put himself under a course of homceopathic treatment. Not that this would inevitably fail to relieve or cure, but that the chance of his speedy recovery is greater in a water-cure establishment than anywhere else. Besides the class of cases which, unfortunately, in this land of luxury and labour, is a very numerous one; there can be no doubt that, as a detergent process to get rid of the accumulation of drugs introduced into the WATER-CURE. 189 body by the officious zeal of old physic, it is in many instances almost a necessary preliminary before successful homoeopathic treatment, and it is held in high esteem by many in the treatment of gout, rheumatism, and skin diseases. Dr. Gully candidly admits he has never cured gout by it, although he has mitigated the severity of the attacks; we rather believe that most homoeopathic physicians would say the same; and it may be a question which of the two systems is most effectual for restraining this cruel disease. Probably it will be found that an alternation of the two will be attended with the best results. In regard to rheumatism, I am inclined to think that there are some varieties of this complaint which utterly defy all homoeopathic medicines from the deeply morbid condition of the blood; and that in these cases a thorough water-course by effecting a rapid and total renovation of this fluid might enable our remedies to act more benefically. That the water-cure, unassisted by specific medicine, cures any of those inveterate forms of skin disease which defy other treatment I see no proof whatever, although I know that it affords temporary relief and transient removal of the complaint in many instances; and I should feel inclined to advise its trial in obstinate cases of lepra and psoriasis, although I disbelieve its power of radical cure in this unmanageable complaint. Having now attempted to ride the marches, as it were, of the province of the water-cure, in its character of an independent power, asserting well-grounded claims over a peculiar and definable class of subjects, let us pass on to the second important consideration of the matter, and try to ascertain what water-appliances may be usefully 190 WATER-CURE. adopted by us as simple auxiliaries to homoeopathic practice. Nothing is more desirable in the present state of homoeopathy than the addition of safe palliatives. This must be felt by all practitioners; and we are constantly in danger of losing cases from our inability to afford immediate relief without risking or greatly retarding the ultimate radical recovery. Take for example a case of long-standing, habitual constipation of the bowels. Is it not most embarrassing either to permit or to countermand the use of some purgative? If we yield to the patients' importunities we retard the cure, and in some measure descend from our vantage ground of principle, although we may be justified in so doing; if we hold out, the patient is made very wretched for many days, even weeks, and he may possibly throw up the treatment in disgust. Now, it seems that water applications of many kinds are agreeable and innocuous palliatives, and it is right that we should number them among our resources. So that we shall briefly detail those which seem to us most useful, and indicate the kind of cases for which each is best adapted. To begin, with much the most celebrated and the most common, CC wet sheet or towel packing," consists of the following process:-a bed is so prepared, that laying a wet sheet upon it shall not injure it. A sheet is dipped in cold water and wrung out so that it shall not drip. It is then spread upon the bed, and the person who is to undergo the process lies down flat on his back upon this wet sheet. The attendant then folds the sheet over his trunk and lower limbs, leaving his arms free. He is then firmly enveloped in five or six folds of blankets, and allowed to remain in this state of humid mummyism for WATER-CURB. 191 about an hour; he then gets out, and a wet sheet is usually thrown over him, with which he is forcibly rubbed; after undergoing this process for a minute or so he is very thoroughly dried with towels, and so the affair ends. This is called wet sheet-packing; but instead of involving the whole body, it is sometimes desired to envelope only a part; it may be the trunk or the chest; in this case a wet towel is substituted for a wet sheet. Although the prdcess has been often described, and there has been a wonderful amount of extravagant talk and writing about it, yet the only attempt at a scientific determination of the physiological effect of this curious artifice of Priesnitz that we are aware of is contained in a work recently published by Dr. Howard Johnstone, entitled 'Researches into the Effects of Cold Water upon the healthy Body, to illustrate its Action in Disease;' and from this work we shall extract some tables of considerable interest, showing the effect of wet-sheet packing upon the action of the heart.

The obvious deduction from these important experiments is, that wet sheet packing acts as a direct sedative upon the heart's action. It does not reduce the whole 198 WATER-CURE. weight of the body to any appreciable amount, so that there can be but little loss by perspiration. The rationale of the operation seems to be, that heat is slowly abstracted from the body, while the temperature of the skin is maintained, so that there is no sensation of cold. In fact, it might be called a slow dose of cold. The fall of the pulse and the general sense of languor and sleepiness are exactly similar to what is described as the first effects of severe cold. And we cannot but regard it as a valuable discovery, that we should be able to command the action of the heart so effectually without producing any unpleasant or dangerous symptoms. There are many cases of over-action of the heart which are in themselves very distressing, and which often give rise ultimately to organic lesions, either of that organ, or of the brain, and which are sometimes difficult to subdue by any homoeopathic medicines; in such cases, I am of opinion that wet sheet packing might be resorted to with great advantage. Of its perfect safety there seems to be but one opinion on the part of all who have had such experience of it as to make their testimony of any value. Next in frequency to the wet sheet packing, both on account of the novelty of the appliance, and its manifold utility is the wet-compress. This consists in a strip of sheeting or table linen of sufficient breadth to reach from the pit of the stomach to the hips. So much of this is wetted as is enough to go round the body except about four inches on each side of the spine, and several plies are then wrapped over it so as completely to exclude the air and prevent evaporation: or, instead of this somewhat cumbrous method, a piece of Mackintosh-cloth is WATER-CURE. * 199 bound over the wet portion. This is frequently worn night and day, and is changed as often as it becomes dry. The operation of this constant poultice is of a very complicated kind. It acts by simple mechanical pressure upon the abdominal muscles, and gives relief in this way: it also acts as a soothing application when there is much irritation of the viscera, so that it has been called an opiate to the abdomen, and is found very beneficial in cases of nervous indigestion attended with sensitiveness of the surface to pressure. Dr. Gully recommends its removal during a meal, especially dinner, and for an hour after it, as it seems to increase the sense of fulness and discomfort in the stomach if worn at that time. Besides acting in this soothing way, it must also operate as a counter-irritant, for sooner or later it causes an eruption of some kind on the part where it is applied. This is not surprising, but it has another very curious effect, which seems to depend upon some endosmosic action, for there is generally, or at least frequently, an exudation of glutinous matter. " In one case," Dr. Gully says (of bad nervous headache in a lady who had taken enormous quantities of physic for it), " I saw an exudation of matters of a brownish hue, which stiffened the compress as if with starch, and gave out the unquestionable odours of colocynth and aloes. It continued for one week in varying quantity, then ceased, and broke out again in five weeks afterwards, continuing for a fortnight, and smelling of aloes, gamboge, and, at times, of camphor. I have often seen colours and smelt odours of various kinds pervading the compress, but could never be certain of either beyond a strong medicinal smell. In the instance alluded to, there was not the 200 WATER-CURE. slightest doubt upon the subject." One of the most important of its effects in a practical point of view for us to be aware of is, that it acts in very many cases as a certain and mild aperient, if worn for three or four hours. It would be interesting to know whether it acted in this way by inducing a transudation of medicine, already in the system, through the skin, or by stimulating the torpid bowels, or by allaying the irritability of the spinal nerves. For it is manifest that the laws of reflex action must come into play when so considerable a stimulant or sedative is applied to the large surface of the abdomen. Indeed, there seems a most interesting field for observation and experiment in regard to the whole modes of action of this and many other applications used by those who practise the watercure, and, I trust, that either Dr. Gully, or some one else of large experience and ability, may, before long, treat the subject in a more scientific and less popular style than has hitherto been the fashion of the writers on this department of medicine. The value of local wet bandages in rheumatic inflammation of the joints is pretty generally admitted. They are used, at least cold water is employed, very freely by Dr. Fleischmann, in the Vienna Hospital, and there seems to be no ground whatever for the notion, at one time prevalent, that there was a danger of their inducing a metastasis to the heart. On the contrary, the allaying of the pain and the subsidence of the local inflammation, tend to prevent rather than to excite endocarditis, which, according to some very high authorities, is a constant attendant, in some degree, of all acute rheumatism. The compress is said to be of use in that form of WATER-CURE. 201 enuresis which depends upon over-sensitiveness of the neck of the bladder. In such cases, it should be worn upon the perineum by means of such a bandage as is used to support the testicles. It is not found generally to be of any avail against neuralgic pains, although it is said that in paroxysms of sciatica, a large wet compress round the thigh gives pretty certain relief. After the compress is removed, the part should be washed with cold water to prevent its too great sensitiveness to the air, on the same principle that the whole surface is spunged after a wet sheet packing. We consider that a case is now made out for admitting the wet compress into our army of auxiliaries, and employing it in various forms of nervous and mucous indigestion as a sedative and aperient, as well as in local inflammations, and as far as my observation goes, it is not only quite harmless, but positively agreeable to most patients. It would serve no good purpose to enter into a minute detail of all the various kinds of baths and other methods of applying water employed by those who practise the water-cure. It will be time enough to do so when they are agreed among themselves as to the particular cases for which each is appropriate. And it is hardly possible to hear without a smile the merciless. criticism with which one frequently dissects the treatment recommended by another; for, in fact, it is as yet an entirely empirical mode of cure, and its promoters explain the benefit derived by totally opposite physiological principles. Indeed, all the books hitherto published upon the water-cure in this country, are full of gratuitous assumptions, many of which are denied by all physiologists, and the others, even if admitted, would 202 WATER-CURE. be refused the exclusive prominence given to them by what might be called the medical unitarianism of the writer. Nevertheless, as it is impossible for the physician to have' too large a supply of resources in the management of the numerous and tedious and complicated diseases he may have to treat, it may be as well to mention one or two of the more favorite processes at present in vogue at Malvern, and I presume elsewhere. One of the most agreeable is the soap-lathering, as it is called. This consists of covering the whole surface with soap, made into a lather with tepid water, by means of a piece of flannel, and then washing it off with pure tepid water. Of course, this is nothing but a simply detergent process, combined with more or less friction. It probably induces a more rapid and healthy exfoliation of cuticle than is usual, even in perfect health, and the soap, by uniting with the oleaginous matter continually being secreted by the sebiparous glands, favors its ready expulsion from their ducts, which are intimately connected with the hair-bulbs, and thus promotes the healthy growth of the hairs. The immediate relief given by this in many acute affections is worth knowing. I have at present under my care a gentleman affected with a very severe and long-continued attack of rheumatic ophthalmia, attended with intense pain in the head. His suffering is immediately relieved by the soap-lathering, and the feverish symptoms abate, and are succeeded by a sense of ease and comfort which it would be impossible for any medicine to afford. The effect is probably due to the soothing influence of the soap-rubbing and washing, reducing the excessive sensitiveness of the nervous system, which makes the other nerves sympathise too keenly with the morbid sensation WATER-CURE. 203 in the eye. Whatever the explanation may be, there is no reason why patients suffering from local inflammations of a similar kind, should not enjoy the alleviation afforded by this simple and cleanly process. And it is so agreeable, that many persons continue it after the reason for its first administration has passed away, from the grateful general sensation it usually promotes in the system. The dripping sheet is another highly fashionable appliance. A large sheet is dipped in cold water and thrown over the patient so as to cover his head, the bath attendant then rubs his whole body very smartly with it, and afterwards dries it with a hardish towel. This produces a pleasant glow of the surface, and stimulates the whole system into a condition of conscious vigour. It is generally used in the morning, and is a very pleasant and healthy kind of cold bath. The sitz bath is so familiar to all practitioners as not to require any special description. The immersion of the lower part of the trunk in water for half an hour at a time, more or less, has often a very beneficial effect in cases of constipation, haemorrhoids, and leucorrhoea. It obviously acts at once as a sedative and gentle stimulant, allaying morbid irritability, and promoting the action of the muscular system of the abdomen. In common, I presume, with most of my colleagues, I have long been in the habit of employing this form of bath, and can confidently recommend it in the class of cases I have just indicated. The douche belongs so exclusively to the province of the water-curist, that it would be profanation on the part of the uninitiated to speak of its mysteries, but 204 WATER-CURE. there is a sort of miniature douche recommended by Dr. Gully, and thus described by him, which is well worthy of our consideration, as he gives tolerably precise indications for its use. " The patient sits on a board placed across the lower end of a shallow or sitz bath, with his back turned towards the bath. The bath attendant then dips a towel into a large can of cold water, and rubs it up and down the length of the spine, not waiting till it is warmed by the patient's body, but constantly changing the water in the bowl, so as to renew the shock of the cold as often as possible. This is continued from three to ten minutes. "The operation of this application will be sufficiently Sobvious from what has preceded. It stimulates by the constantly renewed cold; and the reaction is so great as to amount to the sensation of burning along the track of the spine. Applied, too, as it is, immediately over a great nervous centre, it has a more direct and powerful action on the nerves of locomotion and sensation proceeding thence over the whole frame. By virtue of this it clears the head, when it is confused, pained, or lethargic; it gives alacrity to the limbs, and spreads over the skin a sense of comfort which is due to the stimulus propagated along its nerves. Further, by the sympathy with the organic nerves, it expels flatus from the stomach and intestines, and occasionally acts as a very speedy aperient." So far Dr. Gully. It seems to resemble in its effects the application of galvanism to the spine, and is certainly, on the whole, much more easy of administration, and attended probably with greater advantages. I have seen excellent effects from galvanism in cases of torpid bowels and imperfect digestion, depending on some WATER-CURE. 205 forms of spinal irritation, and for such cases in future I should be inclined to try spinal washing in preference. Hand and foot-baths are frequently used, and are said to relieve nervous headaches. A shallow foot-bath taken at bed-time is undoubtedly useful in warming the feet when they are so cold as to interfere with the sleep of the patient, and the same remark applies to general washing of the whole body before going to bed. With regard to the potations more than pottle-deep of water once so much in vogue, they have rather fallen into abeyance, but are still employed when there is torpidity of the system, and a glass of cold water on rising in the morning not unfrequently procures a motion of the bowels in persons subject to constipation, and supersedes all other treatment. Such is a brief survey of the water-cure from the purely practical point of view, and before closing these remarks, it may be well to point out the kind of cases which we believe are not likely to benefit by it, for the ultimate responsibility falls upon the permanent medical adviser, and not altogether upon the water-cure practitioner. 'He naturally gives as encouraging a report of the probability of a patient's deriving benefit from a course of treatment as he well can, and this added to the sanguine expectation of those who have made a considerable effort to reach the waters of healing, very frequently induces patients to remain for months, and afterwards to leave no better and often worse than they came. For there is this manifest difference between the water system and all others that it cannot be given up at once. The person who undergoes it is told he must expect to be 206 WATER-CURE. worse before he is better, and finding the first part of the promise fulfilled, he lingers on in the hopes of the fulfilment of the second, and at length, after wasting months and undergoing great pain it may be, and certainly discomfort, he has the mortification to discover that his was not a suitable case for the treatment, and returns to his old medical adviser complaining of his disappointment. One of the most distinguished and liberal physicians in the kingdom lately told me, that he very frequently met with such cases, and the observation is corroborated by my own experience. I do not wish to impute blame to the practitioners of the water-cure, but to guard against having too sanguine expectations from the process; for there is something so imposing in the popular description of these places, and in the magnificent water-palaces where the local Neptunes hold sway, and in the whole armament of water power which meets the eye, that it requires considerable scepticism to doubt that before such a stupendous machinery of healing force, disease of every kind must not at once capitulate. However, this is not the case, and, as a general rule, few specific organic diseases seem to be much affected by it, and I believe that cases of spinal irritation and uterine diseases are very often positively aggravated by watertreatment. I mention these two especially, because they have come under my own observation, and because it is rather the fashion to send patients of this kind to some of the water-cure places. Of course it is hardly necessary to say anything about chest-complaints, the common sense of this country is sufficiently alive to the risks persons so afflicted must inevitably run. Neither are renal diseases likely to be benefited, but liver complaints cer WATER-CURE. 207 tainly are very often improved by the water-cure, and some of the most striking cures Dr. Gully has published, are of this disease. However, there are few diseases over which homceopathic medicine has more power, so that it would be unfair to give the preference to the water-cure, although it is quite fair to admit its innocuousness and even great utility in these cases. We cannot conclude without expressing a hope that those who preside over these important institutions may be penetrated with a deep sense of the responsibility of their position, and by the integrity of their conduct, and the purity of their lives, and the dignity of their proceedings, silence the charge of cupidity which is so often advanced against them, and, as they occupy a very prominent place in their little locality, they may set such an example as to give a high moral tone to the devotees who congregate round their shrine, and repress to the utmost the evils naturally engendered by perfect idleness, and the continual meeting of people whose sole subject of interest is their own complaints and those of their neighbours. And as the washing of the body has been accepted in all ages as an allegorical symbol of the purification of the mind, may this symbol be still respected, and may the physician and the patient alike remember that the rite of baptism, if properly pondered, has a daily significance in a christian land. CHAPTER VI. SECTION I. ON SOME AFFECTIONS OF THE HEART. rTHAT diseases of the heart are generally incurable, and suddenly fatal, is a popular, but altogether erroneous idea. No doubt most cases of sudden death arise from some affection of this organ, but the proportion of persons affected with heart-complaint of a necessarily fatal character, compared with those in whom it exists of a kind and in a degree which brings it within the sphere of successful medical treatment, is comparatively trifling: in fact, there is no class of organic affections in which the art of medicine can effect so much, nor any other of which we can speak with so much certainty as to the consequences, both direct and indirect. Nor should thi's surprise us,, when we examine the subje -ct 'witli the calm light afforded by physiology; and by a dispassionate consideration of the nature and functions of the heart, free our minds from the vulgar dr-ead of some impending mysterious and appalihng calamity, which is apt to lurk in the phrase of " disease of the heart." The heart is the most muscular organ of the body, the fibres are more highly developed than in. any other muscle, and its enormous power may be estimated by the SOME AFFECTIONS OF THE HEART. 209 fact, that, although no bigger than the fist, it exerts a force equal to more than fifty pounds.1 This is in its normal state; when enlarged by hypertrophy of its walls its power must be much greater. It has been for long, and still is a question, how far the circulation is due to the heart alone. There is no doubt that a circulation is possible without a heart: the first blood that flows in foetal life flows to, not from, the centre of the circulation; and instances are on authentic record, of foetuses growing to maturity without a heart, and in some of the cases without any communication with a heart, although in general this malformation occurs when there are twins. And after all the heart possesses no structure, nor is it capable of any action which is not also found in a less degree in the arteries and veins; so that, viewed from its mode of growth and transformation, it may be regarded as a portion of artery and vein enormously developed in particular directions; and in some of the lower tribes of animals, it is impossible to say whether they have several hearts or no heart at all, and only a main artery.consisting of a series of pouches. The experiments of various distinguished physiologists leave no doubt about the fact, that both arteries and veins are capable of spontaneous contraction, and the former of dilatation on the application of certain stimuli after the vessels have been removed from the body.2 Although with such evidence before us we cannot doubt, that in primitive and abnormal states of the system, the blood-vessels may powerfully 1This is an approximative statement, resting on the experiments of Keil, Hales, and Poiseuille, and accepted by Burdach in his work on physiology. 2 See 'Verschuir de venarum et arteriarum vi irritabili.' 14 210 SOME AFFECTIONS contribute to the circulation of their contents, yet for all practical purposes, we may safely regard the heart as the sole propulsive force in mature life, and in almost all circumstances, both of health and disease. And the simplest and most correct view to take of its action is that of a machine combining the powers of a force pump and an air-pump: during its contraction acting as the descending piston of the fire-engine, and propelling with great force a column of blood into the arteries, and during its dilatation acting as an air-pump, and sucking from the veins an equivalent amount. And let us add to this simply mechanical idea of the heart, that it is also so largely supplied by nerves of emotion, that every feeling of sufficient intensity provokes in the centre of organic life some corresponding change, and that thus the spiritual and animal existence are here united in wedlock. And hence it is by no accident that the heart is accepted as a symbol of the affections, and has retained this figurative dignity, from the earliest records of our race, and will probably continue so to do to the end-the symbol of a range of feeling extending from that of the devotee kneeling in his cell before the transfixed heart, to the cottage girl blushing over a first valentine. Not only with the brain, the original material source of all mental and emotional perturbation, but with every part of the body endowed with sensation, does the heart maintain an active sympathy; and thus by the pulse is tested how far the general well-being of the animal economy is compromised by any local lesion. To enable the heart to perform its work as a pump, it requires that, like any other pump, it should be provided with valves to regulate the ingress and efflux of the fluid OF THE HEART. 211 whose cujrreilts it urges and directs; and as for such a purpose, muscular tissue is obviously unfit, the internal lining of the arteries and veins is gathered into folds and filled with muscles and tendons, which brace them down when closed, and permit them to flap freely when open. So that we observe, the heart is mechanically the most complicated organ, and functionally, and in its intimate structure, one of the most simple organs in the body. It is this peculiarity which renders the knowledge of its diseases comparatively easy, however difficult their treatment may be. For here we have not to do with inscrutable molecular actions, such as those which originate and regulate the various secretions, the morbid alterations and degenerations of which, are only cognizable, and not explicable-tubercle and malignant transformation generally, for example-but all we have to investigate in diseases of the heart, at least in by far the greatest proportion of them, requires far less knowledge of physics than is to be found in every engine-factory: and by the simple application of facts, plain to the unassisted eye and reason, the whole complicated and dismaying phenomena, which follow a derangement in the structure of the heart, become resolved into the inevitable results of the opening of a valve when it should be shut: as all the horror and disaster and confusion of the explosion of a steamer results from placing a few extra pounds on the safety-valve. Why so much mystery should have been made about the sounds of the heart, is difficult to understand, far more difficult than the matter itself. If there had been no sounds from the working of such an enormously powerful force-pump, with its double set of valves formed 212 SOME AFFECTIONS of elastic material, alternately relaxed, and suddenly, by a violent jerk, stretched to their fullest tension, and this, too, in a chamber full of fluid, and containing also a sensible portion of air, then, indeed, we might be expected to be overwhelmed with wonder. However, we may now look upon the days of this mystery as over; the thing is so simply explained, and the rational explanation so generally accepted, that in future we may be favoured with treatises on heart diseases, which do not occupy a hundred pages in explaining what may easily be done in as many words. If we have once clearly before our eye what takes place in the heart during health, nothing can be simpler than the deductions of the changes that must have preceded the appearance of any morbid phenomena arising from this source. Let us suppose the blood, gathered by the veins from the various parts of the body, and flowing from the great main trunks into the two auricles, which are of a similar nature to themselves, and, indeed, may be looked upon as mere venous pouches, with a large development of muscular tissue; these pouches bear distension with venous blood, which is congenial to their own nature, up to a certain extent, and then, from a sense of being over full, they quietly pour their contents into the two ventricles. But the moment the dividing sluice between the two chambers is open, a sudden change takes place; for, in the first place, the advancing column of blood is not allowed to flow at the sluggish rate impressed upon it by the auricle, it is sucked into- the ventricle with great force,1 and this powerful hollow muscle having I That the ventricle expands with muscular activity, is proved by experiments in which no pinching, pricking, or galvanizing could arrests its ex OF THE HEART. 213 filled itself, discharges its contents with still greater energy along the channels prepared for it-that is, along the aorta and pulmonary arteries, which lie with open mouths to receive the column thus propelled into them, while at the same moment, the valves which separate the auricles from the ventricles flap to like folding doors of hide, and as they close vibrate throughout their whole extent, and set the chords which brace them to the floor of the chamber ringing in unison, and thus the prolonged cleek, the so-called first sound of the heart, is produced. Scarcely a moment after the ventricle has contracted does it again expand, and suck a new supply of fluid out of its feeding auricles, but not out of the arteries, else there would be no circulation-only agitation. To prevent this, the valves which hang at the mouths of the arteries, are closed by the action of the over-distended arteries themselves, which repeat the stroke of the ventricle, and in suddenly shutting their valves make a sharper, quicker sound-a sort of click; hence the double sound, the cleek-click of the heart, which might, without any great stretch of fancy, be compared to the challenge and reply of the two sentinels at the gates of life: the one at the mitral and tricuspid valves uttering its loud challenge, and the one at the semi-lunar valves repeating the countersign in a shriller voice. As it is the same stroke that closes the ventricular valves and sends the blood along the arteries, by which they are made to throb, it is plain that any imperfection in the mitral valve, which gives rise to an unnatural pansion when once begun. See experiments by Fontaine, referred to in the sixth vol. of Burdach's ' Physiology,' p. 301, French translation. 214 SOME AFFECTIONS sound, instead of the "all's well"-cleek, will occur at the instant of the filling of the vessels, and may be perceived by the finger upon the pulse. If the abnormal sound correspond with the beat of the pulse, the chances are, it arises from some mischief about the mitral valve. Of this we shall speak more fully in the sequel, we merely advert to it now as an obvious inference from the construction of the heart. Another equally obvious one is, that the imperfect closure of either sets of valves will allow of a reflux of blood along the channel by which it arrived; if the mitral gate, then it will flow back into the left auricle and oppress the lungs; if the right ventricular valve be deficient, then it will flow back upon the right auricle; and the pulsations of the heart will be transmitted along the great veins, gorging the liver, preventing the proper descent from the heart, and generally impeding the whole capillary circulation; and thus producing dropsy and other-dreadful consequences. And it will readily be perceived, that although at first only one half of the circulation may be affected by the destruction of a portion of one side of the heart, yet that in reality our so-called double circulation is in such intimate union, that neither portion can long remain injured without seriously compromising the integrity and regularity of the other, on mechanical principles alone, independent of the living sympathy which specially unites them. Thus, if we suppose an injury to be done to the mitral valve, so as to make it useless; the first effect will be, that the blood is forced back upon the lungs, the lungs, thus gorged and irritated, are no longer in a fit state to receive the allotted quota from the right ventricle; this part of the machine finds unusual obsta OF THE HEART. 215 cles to contend with, and in accordance with the law of muscular development, waxes stronger and larger in consequence. Hence hypertrophy of the right side, with all its consequences, is the inevitable result of imperfection of the mitral valve. We might prosecute the illustration in all directions, but it is sufficient for our present purpose to bear in mind the fact, that disease of one, part of the. heart will inevitably cause -disease in other parts, if it be allowed to go on, and that, in treating heart complaints, we must regard the organ as a vital whole, and not as merely a pump with two separate and independent cylinders. One of the most gratifying and important objects we attain by an accurate knowledge of the principles by which we can ascertain the real condition of the heart, is, that it enables us to distinguish, with absolute certainty, between nervous palpitation and organic disease, and in this way to give immediate and unspeakable relief to the sufferers, who generally aggravate their distress by their anxiety; and thus simple and certain knowledge becomes a remedial power of the highest value, by extinguishing one of the chief feeders of.the malady. And it is fortunate that the symptoms of nervous palpitation and organic disease, although so nearly alike to the unpractised eye, are yet so essentially dissimilar as to put it in the power of a mere tyro in medicine to assume, without presumption, the dogmatic confidence, without the ambiguity, of an oracle. The stethoscope, here, well deserves its name; it realises the legendary request to Jove, and actually, so reveals the state of the heart, that it could not be more perfectly understood, even though seen instead of heard; and if, by so doing, it 216 SOME AFFECTIONS sometimes communicates a death-warrant, it much more frequently britlgs a reprieve. That an organ so endowed with sympathetic sensitiveness, should be subject to great functional irregularity, is no more than we might have anticipated. The kinds of irregularity arise from three different sources. First, from the heart itself being in a morbidly irritable state; second, from the blood which reaches it being unnatural in its conditions; and third, from the direct over-stimulation of strong emotions, acting through the nervous system. Palpitation of the heart, arising from too great irritability of its substance, may be readily distinguished from that which originates in structural disease, by the suddenness of the accession of the attacks, and the pulsations of the heart, however vehement they may be, not having that force which characterises palpitation from hypertrophy. They rather resemble the flutter of a caged bird than the successive strokes of a hammer. It is not easy to say on what this over-irritable condition depends, and systematic writers on the heart do not seem to have paid sufficient attention to it as a specific affection, which I believe it to be. I have met with it in otherwise robust and healthy men, who have suffered from fevers, especially the Indian fevers, and also in those who had had the cholera, and I am disposed to think, that the animal poisons, which occasion these diseases, act specially upon the nervous tissue of the heart, and leave the organ in a state of preternatural irritability. Whatever be the cause, it is an affection attended with great alarm and distress, and very difficult to subdue. It occurs as frequently in men as in women, and seems not OF THE HEART.21 217 in any way related to the hysterical palpitations which are so common among the latter. Some years agol, I met with a very troublesome case of this kind, an outline of which will better indicate the signification of the term "C irritable heart, " than the mi-ost laboured generic description. I was sent for one night at twelve o'clock, to see a gentleman who lived a few miles out of Edinburgh. Trhe patient was a remarkably vigorous, healthy man, about sixty years of age: I found him in bed in a state of the greatest alarm; he told me that for some hours he had been suffering from the most violent palpitation of the heart, and that he feared he was going to die. On examining the chest I could detect no symptoms of disease; his tongue was clean too, and he did not complain of any gastric symptoms. Except a certain paleness of the face, and this tumultuous action of the heart, which heaved and throbbed in a most irregular and violent manner, there was no other symptom of illness about him. I tried to give him confidence, thinking that the violence of the attack, whatever might be its origin, was aggravated by his alarm at- its imagined consequences; and I gave him a dose of aconite. In the course of half-ani-hour he was a little better, and against his urgent request I went home (it was during the prevalence of cholera, and I did not like to be away at night; besides, I was sure there was no danger). At six o'clock I was again sent for, and I found the gentleman in the same state as before; he said it had come on immediately after I had left, and continued till the time of my second arrival. He was very much alarmed, and expressed a strong wish for a consultation. Dr. 218 SOME AFFECTIONS Henderson was called in; he gave a very decided opinion that there was nothing the matter, and we did what we could to reassure the terrified patient. Ignatia and Lachesis were left with him, to be taken alternately: the attack gradually subsided, and he was restored to his former state of health in the course of the day. The only cause I could assign as exciting the attack, was, that he lived in a large lonely country house, and from being deprived of the society of an only child, he had fallen into a somewhat nervous condition. But there was nothing about his manner or appearance to indicate such a state of the heart. Although this patient seemed perfectly well, yet he died in the course of the following autumn, under the superintendence of an allopathic surgeon, nominally of pneumonia. Whether the violent nocturnal attack of palpitation had any connexion with his subsequent fatal illness, I cannot say; but I can hardly suppose that so peculiar a functional derangement could have gone on for a whole night without some organic cause, and this cause, I imagine, was a condition of excessive irritability of the heart. I had for some years under my care a married lady, who had suffered from almost constant tumultuous and irregular action of the heart, attended at times with very acute pain: she described the sensation as if her heart were tightly grasped. Neither in this case, nor the one just related, was there any material disturbance of the respiration. The absence of this complication may be regarded as decisive against serious organic disease. The case of the lady proved an exceedingly difficult one to manage; she was subject to neuralgia, and of highly organized nervous OF THE HEART. 219 constitution altogether. However it will be best to defer till late all reference to treatment. How far the presence of gout in the constitution gives rise to these anomalous actions of the heart, it is not easy to say; it is quite certain that in gouty people all kinds of odd affections of the heart are met with, and they are among the most puzzling complaints that present themselves to our observation. Among them we place a tendency to faint; from some peculiarity we may call it, perhaps loss of tone in the heart. It is not easy to understand the ultimate pathology of a faint, but in a rough way we may say, that it is either from deficient stimulus being applied to the heart, as in deliquium, from loss of blood, or from deficient activity, and perhaps amount of nervous matter in the heart, on which its contractile power depends. Although generally merely death's image and attended with no danger, yet there seems no doubt that in some csaes it is its forerunner, and in cases where there is no organic change of a scrutable character. This was the case with the distinguished divine, the late Dr. Chalmers. He fainted into death. There was no appreciable disease of the heart, and the probability is that had there been any person present to apply some stimulus.to the inanimate frame at the moment of fainting, he would have recovered. Dr. Hope in his 'Treatise on the Heart,' speaks of members of the medical profession as being very subject to palpitation of heart, which deludes them into the notion of having disease of that organ. I have met with it very often in clergymen. It seems to be a natural result of much mental exertion, combined with anxiety, Of the bodily causes which give rise to it there is none 220 SOME AFFECTIONS so powerful as masturbation, and this may be suspected when we meet with much palpitation in young men without any corresponding wear and tear of the nervous system, or irregularity of regimen to account for it. These are some of the chief forms of inorganic palpitation of the heart which are met with in practice, and I would; before proceeding to remark on their treatment, repeat the observation that they do not seem as yet to have attracted sufficient attention from those who have written specially upon the subject of heart-affections. We must not forget to enumerate among the predisposing causes of this affection what I believe to be one of the most common, an over-indulgence in tea, coffee, and tobacco. How far the health of the next generation will be affected by the substitution of these stimulants of the spinal cord and nerves, of the sympathetic or respiratory system for the alcoholic stimulants, whose action was chiefly confined to the brain, is a question which ought to make us pause, to say the least, before we yield implicit faith in the regenerative efficacy of teetotalism. There is one obvious danger connected with tea and coffee as compared to wine, that they are insidious in their operation, and not being intoxicating have a certain moral respectability which makes it difficult to attack them successfully, whereas the evils of excess in wine have been painted with a passionate vividness manifestly inspired by itself. Of course we do not mean to defend excess in either; all we wish to do is to point out the danger of tea and coffee, and tobacco, and to warn those who satisfy themselves with having avoided OF THE HEART. 221 the Scylla of the wine-cup, to beware of the Charybdis of the tea-pot. Of the medicines best suited to relieve this kind of of palpitation, I have most confidence in the following: A,8safcelida is particularly useful in the palpitation of females, in whoni the heart is irritable, and when the cause of the attack is some suppressed secretion or bodily exertion. The symptom that seems to point to it most is "pressure in the region of the heart, as from congestion and distension of the vessels, with small pulse." A small and infrequent pulse, with violent action of the heart, and no disturbance of the respiration, indicate nervous weakness of the organ, and for such a state assafcelida is often useful. Baryta carbonica has the following characteristic symptoms: "Throbbing stitches in the left side of the chest from the pit of the stomach upwards. Violent beating of the heart in the first fortnight. Palpitation of the heart when lying on the left side, renewed 6y tklinkiyjq of it, with feeling of anguish mostly at noon." The italicized clause seems to show that the palpitation was of a directly nervous kind, and not from any sympathetic action connected with the gastric symptoms this medicine produces. Canpor has certainly a most powerful effect upon the heart, and may be given with great confidence in such affections, especially if the palpitation is attended with coldness of the surface and paleness of the face. The symptom most indicative of its relation to the heart is" after a meal he feels and hears his heart beating against the i~bs." However, its value in practice is not 222 SOME AFFECTIONS fully expressed by the proving, probably on account of the transient character of its action. Carbo animal. and ve etab. should not be lost sight of, but these will be more appropriately taken in the next class of disorders of the heart, and another medicine of whose efficacy in allaying this kind of palpitation I have no doubt, has but few or indeed no symptoms in its proving indicating its virtue, and that is coffee. A cup of good strong coffee will be found to give immediate relief in many cases of palpitation from irritable heart, even when that does not arise from derangement of digestion through errors in diet. Coniurm has a powerful and direct action on the heart, and is suitable to many cases of palpitation. Among its symptoms we find-" Violent palpitation of the Aheart after drinking. Palpitation of the heart when rising from bed. Frequent and visible palpitation. Frequent shocks in the region of the heart." Cotyledon umbilicus, according to the excellent proving of Dr. Craig, seems likely to be valuable in this class of affections. In his physiological sunmary he says" The character of the Cotyledon-symptoms of the heart, lungs, throat, and mind, correspond very closely with that of the effects produced on these organs by strong emotions when suppressed." "Full, bursting feeling, as if from obstruction of the heart." Further on he says, " a pathological group of symptoms, similar to that first mentioned, is observed to occur when the functional lesion begins at the heart. Violent exercise, as quick running, for instance, occasionally produces the same obstructed feeling, and this functional difficulty is not unfrequently so persistent, as to become the subject of OF THE HEART. 223 medical treatment, I would expect benefit from the use of Cotyledon in such a case."' Digitalis.-" The action of Digitalis on the circulating organs,"' writes Dr. Black in an able treatise upon this medicine, published in the fourth volume of 'The British Journal of Homoeopathy,' "is very characteristic: the heart becomes irregular and weak, palpitation readily excited, attended with uneasy sensations in the chest, especially in the left side; in some instances amounting to pain, and extending to left shoulder and upper part of arm; in others there is distressing precordial anxiety. Palpitations are readily excited in bed when lying on the left side. The pulse is slow, but much more frequently quick, weak, and fluttering, and frequently intermittent; but the marked change is the facility with which the pulse is rendered irregular and the heart's action laboured. So diminished does the power of the heart become that fatal syncope has been produced by the patient suddenly changing his position." And again, speaking of its therapeutic action, he says" It may be administered in functional derangement of the heart. In two cases where no other disorder of consequence existed, I found it useful; these two cases were characterised by very frequent and distressing palpitation, with a quick, weak, and slightly irregular pulse." So that we may give Digitalis a high place in the treatment of the palpitation from an over-irritable heart. Gratiola has a decided action on the heart, as indicated by the following symptoms-" Strong and quick palpitation of the heart. Violent palpitation of-the heart, S' British Journal of Homceopathy,' vol. x, p. 616. 224 SOME AFFECTIONS which shakes the whole body, and seems to proceed from the pit of the stomach." Hcematoxylum campechianum seems to have a special relation to the heart. Among its comparatively few symptoms we find the following-Pain in the region af the heart, with sensation as if a bar were extending from the heart to the right side, and violent pain in the left upper region of the heart; great painfulness of the region of the heart; oppressive anxiety; increased beating of the heart; small pulse; hot hands; chilliness over the whole body. Palpitation of the heart (with diminution of habitual sweat of the feet). We omit Ignatia, as its action upon the heart is not very well marked, although it is useful in palpitation caused by emotions. Among the imponderables are magnetism and mesmerism. The use of the magnet in angina pectoris is highly recommended by Laennec, and among the symptoms of the South Pole of the Magnet, we find palpitation of the heart italicized. Mesmerism has a direct and powerful influence on the heart's action. I once saw an American mesmerist stop the action of the heart in a young man. The place was at the house of a distinguished Professor of the Edinburgh University, and besides myself there were only other three or four persons present, two of whom were men of high scientific attainments. The subject of the operation was a student of about twenty years of age. The operator pointed his fingers at the cardiac region while I felt his pulse. Very soon it became quick and weak, and in the course of about two or three minutes entirely vanished, as the pulse disappears in a cholera patient. He became OF THE HEART. 225 ghastly pale, but did not fall. After the operator ceased the heart slowly resumed its natural functions. From this experiment, as well as from my own observations, I feel satisfied that great and immediate relief may be frequently given in palpitation from irritable heart, by applying the palm of the hand to the cardiac region. lodium has a well-marked action on the heart: we find "Violent pulsations in the chest and palpitation of the heart, increased by every muscular exertion to such an extent that she was unable to support herself for one minute without being near fainting. Palpilalion of Ike heart which might have been heard at the distance of a few paces. Palpitation the whole day." Kalmia latifolia is highly recommended by Dr.Hering, who says no medicine except Digitalis has so much influence upon the pulse. The indications for its special use are not, however, very pronounced in the proving. In iuy own practice, I have given it, but with entirely negative results, in a case of simple hypertrophy combined with nervous irritability. Of Lachesis I need hardly speak, its.action in these cases is so universally acknowledged, and I can from personal repeated experience testify to the great efficacy of the poison of the Naja trip. I have now given it in several cases of palpitation of long standing with the most decided advantage. One was that of a lady about fifty years of age, who for about a year had been constantly distressed with almost unintermitting palpitation. No organic disease existed, and it was from the other symptoms manifestly an example of irritable heart. I gave her a dose of the one hundredth of a grain of the Naja poison, and the relief was almost immediate, and 15 226;SOME AFFECTIONS the palpitation did not return for about six weeks, when it was again relieved by the same remedy. Another case was that of a dissenting minister, who suffered severely from this cause after preaching, and had tried with more or less success from time to time various homoeopathic medicines. In this instance, too, the relief afforded by Naja was rapid and enduring. I have no doubt from my own experiments, and from these and other similar facts, that the heart symptoms will occupy a prominent place in the proving of this medicine. fMercurialis perennis.-From this medicine we should expect good service in this class of affections: we find among its symptoms-Confused, undulating sensation in the region of the heart, with fulness and feeling of anxiety in the left chest. Oppressive contraction in the region of the heart. Peculiarly undulating and throbbing motion in the region of the heart, the precordia and the upper part of the abdomen; or a remarkable rolling and throbbing, with trembling or undulating in all the blood-vessels without heat: he feels the pulsation of the abdominal arteries when sitting down. Repeated palpitation of the heart with oppression. After having stooped, palpitation of the heart with oppression on the chest, as if the heart were laced tight. Although Secale cornutum more properly falls into the next division, yet it may be also useful in simply irritable heart, as we find it produces-" Violent palpitation of the heart with contracted and frequently intermittent pulse. Spasmodic throbbing of the heart. The beats of the heart are diminished from ten to fifteen in a minute, one horn- after the exhibition of Secale." Sepia has many distinctive symptoms of relation to 0]? THE HEART.27 227 this affection, e. 9c.-" Gurgling or bubbling sensation in the left chest. Beating in the pit of the stomach in the morning, followed by orgasm of the blood in the chest, resembling palpitation of the heart, afterwards burning heat in the face and body, without any heat or redness being perceptible to the hand, and without thirst, but somie. sweat. Beating of the heart in the evening for a quarter of anl hour. Palpitation of the heart with stitches in the left side of the chest. Palpitation of the heart with feeling of anxiety, obliging one to take deep breath, without depressing the spirits, for several days. Intermission of the beats of the heart with anxiety." In regard to general treatment the great rule is to restore the strength of the nervous system by a wholesome and generous diet. I have observed this state of the heart produced by too rigid adherence to rules of ascetic severity, especially by patients who had adopted the water-cure notions, and believed in water to the exclusion of all other beverages. These true hydropathists, or water-sufferers, frequently take no food after their Zghostly tea which is taken about seven o'clock. T~his is.insufficient- for the restoration of the nervous exhaustion, and they ýawake at three or four o'clock in the morning with palpitation of the heart. I have seen this nervous palpitation entirely cured by the bold administration of a chop and glass of wine or spirits and water for supper. The next class of palpitation of the heart to which we shall advert, is what is called the anammic, or that which depends on a deficiency of blood. The abstraction of the sanguineous fluid produces effects commensurate in magnitudze with the importance 228 SOME AFFECTiONS of "the blood which is the life," in the figurative language of Scripture, or in the scientific phraseology of Bichat, which bears in all the tissues of the body a direct proportion to the amount of vitality they are capable of displaying. To what extent this primary element of life may be withdrawn without extinguishing vitality, has been the subject of many experiments which offer considerable differences in their results. According to those of -Rosa, Hales, Blundell, and Piorry, the medium amount required to be withdrawn before death occurs is about three fourths or seven eighths of the whole, but in many cases a much smaller quantity is followed by fatal consequences. It does not require anything like this amount, however, of loss to produce a violent effect upon the system, and the symptoms of anaemia form a well-marked group which is thus described by Hope-" The complexion is unusually, sometimes singularly pallid or exsanguine; the lips, the in-' terior of the mouth, and the inside of the palpebrwe, partake more or less of the same paleness; the pulse is quick, small, weak, and jerkin#q (the pulse of unfilled arteries), and during palpitation it often presents a thrill; its average frequency is generally from 80 to 90, and during excitement is easily raised to 120 or 130, and occasionally even to 140 or 150. The slightest causes, even corporeal efforts, suffice to produce palpitation, breathlessness, and faintness; the body is usually constipated, there is anorexia, with an especial distaste for animal food, and a predilection for sour articles, as acids and fruits, salads, &c. The catamenia are deficient, and usually replaced with leucorrhcea; or, what is too often over-looked, they are profuse, lasting from six to ten OF THE HEART. 229 days, consisting of blood instead of the normal secretion, and, in fact, constituting a passive hemorrhage, which is often the cause of the anemia; the muscular system is very feeble, lassitude and aching pains being produced by trifling exertions; the intellectual powers and energies are also often greatly impaired. In many patients there are transitory neuralgic stitches and aches in various parts of the body, and sometimes exquisite sensitiveness of the skin, especially that of the mamme and abdomen; more or less headache is almost always experienced, generally with vertigo, rushing noises in the ears, and in severe cases, with intolerance of light and sound, delirium, and even fatal coma, of which I have recently witnessed two instances. Such are the general signs of anemia, and, therefore, of anemic palpitation. We proceed to the physical signs. The impulse of the heart is less remarkable for force than for an abrupt bounding character, with throbbing of the arteries, often universal, and a jerking pulse. Hence this species of palpitation is more audible to the patient than perhaps any other, the sound appearing to rush through his ears, especially when he lies on his side in bed, and each arterial throb causes a movement of his pillow. When the anemia is considerable, palpitation occasions a weak soft bellows-murmur in the aortic orifice with the first sound, and a corresponding whiff is heard in the carotids, subclavians, and other considerable arteries, especially when compressed with the edge of the stethoscope. These murmurs of the heart and arteries occur whenever the action of the organ is excited, and in some patients the slightest causes suffice to produce the excitement. Venous murmur invariably attends these murmurs in 230 SOME AFFECTIONS the heart. The following characteristic case is related by M. Bouillaud.x " I was summoned," says he, " on August 21st, 1834, to see, with the surgeon-major of the 3d Lancers, the son of a chef d'escadron, aged 16, who, after a leech-bite, had lost an enormous quantity of florid blood, very probably furnished by a small divided artery; syncope was imminent; lips and face colourless; eyes turned up and livid; general coldness; long and sighing inspirations; pulse exceedingly quick and weak; on listening to the beats of the heart, which were feeble, but very abrupt and frequent, so as scarcely to admit of being counted, I heard a clear smart bellows-murmur, like the puff with which one blows out a candle. I made the surgeon-major and assistant attest the phenomena. I was of opinion that the murmur depended solely on the fainting and anmmic state, during which, from the hurried palpitation of the heart, the smaller column of blood contained in the ventricles was expelled, if not with much force, at least with a sort of convulsive rapidity. I revisited the patient on the following day at the same hour: the haemorrhage had ceased for more than twenty hours; there did not exist a trace of the murmur, which, according to the surgeon-major's account, had completely disappeared ever since the preceding evening." In this case there was no organic disease of the heart. The anaemic murmurs may be distinguished from those arising from organic disease of the organ, by being always confined to the aortic orifice and attending only the first sound, and by being invariably accompanied by S'Trait6,' ~ i, p. s10. OF THE HEART. 231 venous murmurs, and by being of a soft, weak, and bellows sound. The anaemic palpitation may be distinguished fromi the nervous and dyspeptic by being very much aggravated by any movement, however slight, whereas the other kinds are often relieved by gentle exercise. In the treatment of anamic palpitation, the most important remedy is undoubtedly some preparation of iron. That the operation of this medicine is not chemical but dynamical, is proved beyond a doubt, by the success of the infinitesimal dose. I lately met with the following striking case which may be worth recording, as illustrating this class of affections. I was sent for, one night about ten o'clock, to see a patient whom I had not seen before. I found a young lady, about twenty years of age, lying on a sofa, deadly pale; she could not speak, but tossed her head and arms to and fro, and seemed in a state of extreme agitation. The action of the heart was visible through her clothes, it was bounding and throbbing in the most violent and tumultuous way; the pulse was so small and rapid that I could not count it. Not having a stethoscope I could not determine accurately the state of the sounds, but they seemed to me normal. I gave her Ignatia, and remained with her some little time: the attack gradually subsided. I saw her on the following day, aid found her of a pale waxy hue, the lips almost colourless; she complained of great languor, giddiness, ringing in the ears, and occasional headache, and on inquiry I was told that the catamenia was very profuse and too firequent; she was very weak, and had been in this state for about six months. I ordered her a close of 232 SOME AFFECTIONS the fir~t dilution of Ferrum aceticum,' a drop three times a dayi In the course of a week there was the most wonddrful improvement in her appearance-indeed she hardly looked like the same person: she said she felt a great deal better every way. The course was continued for another week, and the improvement went on. Finding herself so well, she left off the medicine, and at the expiry of a week she had again an attack of palpitation, though not so severe as on the former occasion, and she had fallen off in her appearance, being again much more pallid. She resumed the use of the Ferrum, and she was soon restored. When we calculate that the total quantity of iron taken could not amount to a. grain, the idea of its acting chemically is out of the question. Among the other medicines suitable in anemic palpitation the following are the most important: C/ina officinalis affords this peculiar indication. " Strong violent beats of the heart, with feeble pulse and cold skin." It is generally useful when there is exhaustion of the vital powers, accompanied with a tendency to passive haemorrhage. Noack and Trinks recommend it in palpitation of the heart from loss of animal fluids, and in palpitation of the heart with distension of the veins. I have always found this medicine fully answer all that we have a right to expect from it. Graphites is more indicated when, along with anaemic palpitation, there is amenorrhcea, while the two former medicines are more useful when the menses are overabundant. The special symptom expressive of its relation to this affection is, "violent throbbing about the 1 This is not a good preparation of Iron, it is not easy to get a good soluble one. I now often give the Ammoniaco-citrate. OF THE HEART. 233 heart and in the rest of the body at every little movement." Natrum muriaticum has the following characteristic symptoms. "Palpitation of the heart from the slightest movement; palpitation of the heart while standing; palpitation of the heart without anxious thoughts, even for hours; fluttering motion of the heart; irregularity of the beats of the heart." It is recommended by Rmumel in cases of protracted chlorosis, with deficient nutrition and flaccid torpid skin. This too, is most likely to be useful where there is amenorrhoea. Plumbum must not be omitted from this list, although the symptoms which correspond with the affection are not very well pronounced. Among them we find, " pain in the region of the heart, and violent spasmodic palpitation of the heart, and in violent palpitation of the heart." It is also useful in so-called chlorosis, although the term is somewhat vaguely used.' Pulsatilla is useful in the early stages of anaemic palpitation, but the indications for its employment are not very precise. Secale cornutum and Sepia we have already adverted to as useful in irritable heart; they may be given in cases of anaemic palpitation with great advantage. Secale, when there is too great thinness of the blood, and tendency to excessive menstruation, with general erethism of the system, and especially if the skin is marked with livid spots which come and go. And Sepia when there is deficient menstruation. Anaemic palpitation of the heart being much more SSee a paper by Dr. Chapman, in vol. iii, p. 170, of the 'British Journal of Homoeopathy.' 234, SOME AFFECTIONS common in women than men, perhaps an undue prominence has been given to the symptoms of the catamenia; however, the practical physician will have no difficulty in selecting the remedy proper for a male patient, if he be familiar with the characteristic peculiarity of each medicine in its relation to females. The only division that now remains to be noticed is palpitation from moral causes. Although the phrase, " dying of a broken heart," may be slightly figurative, yet it is a certain fact, that, depressing emotions, such as long sorrow or anxiety, not unfrequently induce a constant palpitation of the heart, which may go on to hypertrophy and death. I have at present under my charge such a case: the palpitation began some years ago, and has never altogether subsided; it was caused originally by grief from a brother's and father's death. There is in this case very great hypertrophy with all its attendant dangers. However, we wish at present to speak of simple palpitation without hypertrophy; and for relieving this the best medicines are Aconite, Ignatia, Moschus, Pulsatilla, and Tabacum. Aconite has so direct an action on the heart that it is not easy to make out, from the proving, what may be called its sympathetic relations to that organ. But there is ample evidence for the beneficial effects of Aconite in palpitation caused by grief or fear, or indeed by any mental emotion. The indications for its preference must be sought rather in the general condition and habit of the body of person, than in anything peculiar in the symptoms of the palpitation. Ignatia, according to Hahnemann, whose authority on matters of this kind is altogether paramount, is most suitable for persons subject to sudden alternations of OF THE HEART. 235 feeling, passing rapidly from grief to joy-in short, of mobility of temperament; and it is most serviceable in allaying the evil consequences of anger or grief, if the subjects are not given to paroxysms of anger, but rather tend to the concealment of their feelings. Among its characteristic symptoms is "palpitation of the heart during deep meditation." Moschus is an invaluable remedy in many of the slighter cases of palpitation combined with hysterical symptoms. It does not seem to be so deep in its sphere of operation as either Aconite or Ignatia, corresponding rather to the general tendency to perturbation of the nervous systems when set with too fine an edge, and allaying the excessive action of the whole, than bearing special relation to the heart; and its action is well expressed by this symptom: " great anxiety with palpitation of the heart, as from anxious expectation." Pulsatilla is useful after Aconite in palpitation caused by sudden fear, grief, or annoyance. There are no very specific indications afforded by the proving to give precision to the selection of this, in preference to other medicines, in simple palpitation from moral causes, and so we must fall back upon the general suitability of Pulsatilla to particular temperaments and states of body. Nor can we say more of the last medicine in this list, Tabacum. That tobacco produces a most powerful and direct effect on the heart is certain; among its symptoms we find, "violent palpitation of heart," and that it also acts upon the spirits, producing great depression, is equally well known; and we may safely say, that from these two indications of its action, the one on the brain, the other on the heart, we shall find a most useful remedy 236 SOME ORGANIC DISEASES in this form of palpitation. I have given it occasionally in such cases, but have not sufficiently full details of the cases to make them of any avail. However, my impression is in favour of the important usefulness of the much calumniated herb. In this enumeration of the various kinds of palpitation of heart, I have omitted all reference to those which are simply sympathetic and incapable of self-continuarnce after the removal of the exciting cause; as for example, the numerous fornis of dyspeptic palpitation, for these affections can hardly be the subject of individual and specific treatment; and I have reserved for future consideration all those forms of palpitation which depend upon some organic change in the heart. SECTION II. ON SOME ORGANIC DISEASES OF THE HEART. HYPERTROPHY OF THE HEART. THE natural size of the heart, according to Laennec, is about that of the fist of the person; its weight should be from eight to nine ounces; the four cavities'should be of nearly the same size; the walls of the left ventricle ought to be considerably more than double the thickness of those of the right. It may increase in all its dimensions, its walls becoming thicker and its cavities larger, to such an extent that the left ventricle alone will admit an orange, and the weight of the whole rise to between OF THE HEART. 237 two and three pounds; or its walls may become thicker, and thus diminish its cavities, to such a degree that one of these will hardly admit a small walnut; or lastly, the cavities may be enlarged at the expense of the walls. The first, which is much the most common, is generally called simple hypertrophy; the second concentric hypertrophy, or hypertrophy with contraction; and the third, eccentric hypertrophy, or hypertrophy with dilatation. Each of the cavities may be singly affected, but the ventricles are so much more liable to it than the auricles, that for practical purposes dilatation or hypertrophy of the auricles need not be considered; and of the two ventricles the left is much more apt to become hypertrophic than the right. The causes which induce these changes in the structure of the heart are, either impediments to the flow of the blood through its natural channels, some diseased condition of the substance of the heart itself, some undue restraint upon its movements, or a combination of two or all of these conditions. Almost all diseases of the valves, by overworking the ventricles, induce an increase in their growth and size; and besides this obvious and easily detected cause, there is sometimes a narrowing of the channels through which the blood flows, which can only be detected after death. Andral, in his 'Treatise on Diseases of the Chest,' mentions several cases of this kind; in some the contraction of the aorta and pulmonary artery were truly surprising, these vessels being no larger than the usual size of the carotid arteries. It is of great consequence to bear this fact in mind, for persons affected with such congenital malformations may enjoy perfectly good health for many years, the heart, by the slowness of 238 SOME ORGANIC DISEASES its contractions, accommodating the supply of its contents to the narrowness of the receiving vessels, but when by any sudden and long-continued exertion or agitation a turbulent 'and energetic action of the heart is engendered, then a permanent incurable and rapidly fatal disease of that organ ensues. Thus the practitioner requires to guard his prognosis of the curability of a case of simple hypertrophy which is generally favorable, by specifying the possibility of some conditions existing beyond the plummet of our science to sound. Another ground of caution is suggested by the microscope, for this reveals that in hypertrophy of the substance of the heart the muscles are not in a natural state, there is deficiency of transverse fibres and a superabundance of fatglobules, so that, according to Rokitansky, this affection is allied to fatty degeneration. It is these considerations which make us fear that Hope, in his otherwise trustworthy treatise on this subject, "has told a flattering tale" of the success which we may securely anticipate from judicious treatment. His reasoning at first seems p1lansible. "After all," he says, " what is hypertrophy of the heart but overgrowth of a muscular structure; now we know that muscles are easily reduced in size, as may 1)e seen by tying up a blacksmith's arm, how soon it shrinks; all we have to do is to lessen the work of the heart, and it too will shrivel into more healthy proportions." We admit the deduction, but how shall we give the heart rest? The heart must go through its work well or ill, it cannot lie by for a week, not for a minute, and we cannot secure it from sudden and violent exertion, for even if we could always command absolute bodily repose, where is the physician who can secure his OF THE HEART. 239 patient against mental agitation? Not only are we unable to ensure the external conditions for certain recovery, but we are too ignorant of the molecular changes which accompany the diseased state of the muscle to be at all sure of arresting or modifying their progress. Hence, although we firnmy believe that with our superior therapeutic appliances we are in a much better position than the old school to manage with success this malady, yet we must always look upon hypertrophy of the heart, if of any considerable amount, as a most formidable and even dangerous disease. Another frequent predisposing cause of this affection is the result of pericarditis; for if this be not perfectly cured, instead of the effused lymph being absorbed it forms bands over the substance of the heart which oppose an impediment to its natural action, and in order to overcome this obstacle great efforts are made, which by the law of muscular development necessarily increase the size of the muscle. Of the exciting causes which give rise to hypertrophy, the most important are violent physical exertions, longcontinued moral excitement, and excess, either in stimulating drinks or other indulgences. It is said to be a common consequence of rowing-matches at Cambridge, and of ascending mountains, and hence it is of importance to warn young men of the danger they incur from exploits of this kind. When the disease is once developed there is no great difficulty in recognising it. Even without the aid of the stethoscope we can generally detect by the hand laid over the cardiac region the strong blows of the heart as it beats against the walls of the chest. The pulse in sim 210 SOME ORGANIC DISEASES pIle hypertrophy of the left ventricle is regular, full, and frequently jerking; when both ventricles are affected the pulse is often irregular, and there is always more or less difficulty of breathing. It is not easy to determine with certainty whether the right or left ventricle is most at fault by physical diagnosis, although it is said that in the case of its being chiefly on the right side, which is a rare variety, the beat of the heart is felt more towards the sternum. As we should expect on anatomical grounds in this form of the disease, the breathing is more oppressed and haemoptysis is more common. However, as it rarely happens that the right ventricle is enlarged without some corresponding change in the left, the differential diagnosis is not of much practical importance. It certainly is rather surprising that a disease which one would suppose could not fail to attract the attention of the patient, should frequently exist for a long time without being discovered. And yet the best authorities on the subject inform us that it is no uncommon occurrence for persons to come to the hospitals labouring under very great hypertrophy of the heart, so great as to be discernible even through the clothes, and yet quite unconscious that there was anything the matter with them in that quarter. I had at the same time three cases of heart disease under my care: in the one there was very great hypertrophy; in the other extensive disease of the valves, of fifteen years' standing; and in the third aneurism of the aorta; all of them must have suffered for a long time from unmistakable symptoms of organic disease of this organ, and yet none of them had the least idea of this till I told them of it, and attributed their bad health to derangement of the liver, for which they OF THE HEART. 241 had been treated with great assiduity by the good old school of medicine. Hence the importance of instituting a careful examination of the chest in every case where the symptoms are at all suspicious, for mistakes are much more frequently made by simple negligence than from ignorance, and the consequences of such mistakes if they happen to a practitioner of homceopathy are most serious. Among the indications which should lead us to suspect hypertrophy of the heart is a peculiar brilliancy of the eye, and even a tendency to protrusion of the ball. This is attributed to the increased force with which the blood is forced into its substance by the ophthalmic artery. There is also much-pain in the head, and frequently a constant beating or ringing in the ears. In a case of aneurism of the aorta lately under my charge there was a curious modification of beating sound in the ear, which I do not recollect to have seen alluded to by any writer on this subject. As long as the patient was erect he heard the beating in his left ear alone, but when he lay down the noise was heard only in the right. The explanation seems to be that the aneurism involves that portion of the aorta from which both carotids spring, and that the arch being more curved by the weight of the heart when he is erect, the chief impetus of the blood is directed along the left carotid, which is then more in the line of the column as it leaves the heart; while on lying down the arch assumes a larger curve, and the force of the stream is first felt at a point of the aorta beyond where the left carotid has its origin. At least this is the only explanation of the fact, of which there is no doubt, that I have been able to imagine. In advanced cases the violent action of the heart may be seen distending the 16 / 242 SOME ORGANIC DISEASES carotid artery, and the jugular vein is generally enlarged, although, except when there is also imperfection of the valves, it does not pulsate synchronously with the arterial pulse. Formidable as hypertrophy of the heart is in itself, even more serious must we regard it when we consider the dangers with which it threatens other vital organs; and first in the list of dangers we find apoplexy. It is only of late years that the close connection of these two diseases has been accurately ascertained. Out of 39 cases of fatal apoplexy which occurred at the Marylebone Infirmary, when Dr. Hope was physician to that institution, in no less than 27, or nearly three fourths, there was disease of the heart found to be present on examination after death. But large as this proportion is, it by no means gives an adequate idea of the danger from this cause, for this number includes all the cases of apoplexy that occurred, and several of these were either at an earlier or later period of life than that at which apoplexy is most common. The apoplectic decades in human life, so to speak, are from 40 to 50, and from 70 to 80, and these are the precise periods when disease of the heart is most frequently the cause of the fatal stroke. In nine out of ten observed cases of apoplexy occurring between 40 and 50, and in ten out of eleven occurring between 70 and 80, there was disease of the heart present. The reason of these two periods being more liable than any other to this fatal complication appears to be, that in the former the muscular power is at its maximum, and the force-pump sends the blood to the head with the greatest violence. After 50, there is a diminution of the energy of the muscles, but then a little later the changes to which OF THE HEART. 24.3 we have before adverted of the substance of the bloodvessels themselves, are more frequently developed, and thus their walls are weakened and are less able to resist the impetuous stream that has up to that time been rushing with impunity through the channels of the brain. These well-established facts suggest this serious practical reflection. In apoplexy of old age no good is likely to accrue from the abstraction of blood, because this will not prevent the rupture of an ossified or otherwise disorganized cerebral artery, and the first intimation of the attack will be the symptoms produced by the effusion of blood into the substance of the brain. Medical aid is not sought till the mischief is done, and nothing remains but to make the best of the wreck, with the melancholy certainty that before very long another, and perhaps yet another attack must take place, and quench entirely the life which may have lingered for some years in the paralysed and half dead body. Sometimes, however, the attack is not so instantaneous, and then the administration of homoeopathic remedies may avert it. The only case of this kind I ever met with was in a lady of about 74 years of age-her brother and sister, I believe, at all events more than one near relation, had died of apoplexy. She seemed in her usual health when she suddenly felt an oppression of the head, and when I saw her in an hour or two afterwards I found her lying in a state approaching to coma; the breathing stertorous; the pulse slow and full; the mouth drawn to one side; in short presenting all the characters of incipient apoplexy. I gave her Arnica, Nux vomica, and afterwards Lachcsis, and in the course of the night she gradually recovered, and is now, after an interval of some six or seven years, perfectly well. 244 SOME ORGANIC DISEASES In such cases the question of the propriety of bloodletting can scarcely be mooted, it is not countenanced by pathology, and would hardly be recommended even by an old school practitioner. But suppose we are called in to a man of 45 years of age, of a robust muscular frame, and find him insensible and the pulse thumping away like a sledge hammer; suppose on applying the ear to the chest we detect hypertrophy of the heart, and are thus convinced that there is instant danger of the rupture of a blood-vessel from the enormous impetus and quantity of blood that is driven into the vessels of the brain, in such a case shall we open a channel for the escape of this destructive stream, that threatens every moment to break down the dykes of life? This seems to me rather a question of hydraulics than of pathology. The relief to be derived from bloodletting can scarcely be doubtful, and the only counter question we can put is, have we in our pharmacopoeia remedies as certain and as speedy as bloodletting, and will bloodletting prevent their use P From my own experience I am unable to give an answer to this question. I am thankful to say I never saw such a case, but I think it a cowardly thing not to look the danger fairly in the face, and have our minds made up as to how we should act in such an emergency. And for my part I am free to avow, that if I found such a state of things as I have just described, I should feel disposed to call in a surgeon, and bid him do his duty, and bleed my patient, as if he were his own, leaving the after treatment and the responsibility to me. These remarks are perhaps equally applicable to another dangerous consequence of hypertrophy of the OF THE HEART. 245 heart, I mean apoplexy of the lungs. This, as we might naturally expect, is more likely to follow hypertrophy of the right than of the left ventricle; it is attended with intense oppression of the breathing, and may be recognised by sudden and circumscribed dulness of a portion of the chest. The danger to life is hardly less imminent than in cerebral apoplexy, and the distress much greater. All writers concur in stating the relief by a copious abstraction of blood to be immediate, and for my part I question whether we can conscientiously register a vow in heaven not to practise it in such a case. Besides sudden sanguineous effusion into the chest and head, serous infiltration of the lungs and cellular tissue are common consequences of organic diseases of the heart, with or without affection of its valves. Although this form of dropsy is seldom rapidly fatal, yet there are instances on record of suffocation from this cause taking place in twenty hours. Such a case is related by Andral, who saw a patient pass from a condition of perfect organic soundness of the lungs to suffocation and death within that period of time. Dropsy of the body, however, is never so rapid in its progress, and it may be laid down as a rule, that when this dreadful complication arises from disease of the heart it always affects the upper and lower extremities simultaneously, and the hands and feet swell at the same time; if ascites be first discovered, we may safely presume it is not directly caused by the condition of the heart, but is probably owing to an intercurrent attack of peritonitis. Although for some time the upward progress of the dropsy may be slow, and although it may be restrained by proper treatment, yet it is almost certain to recur 246 SOME ORGANIC DISEASES again and again, each attack being more unmanageable than its predecessor, till it bids defiance to all our remedies; and then, when the limbs are swollen almost to bursting, and the patient cannot rest either night or day from the uneasiness he suffers, it may be a question whether we should not give him temporary relief by allowing the fluid to escape by small punctures in the skin. Of course we know that relief so obtained is merely temporary, and that there is danger of the punctured spots becoming gangrenous; still in such desperate cases I think we are entitled to employ measures which in other circumstances we would reject. While organic diseases of the heart tend thus to destroy the patient by sudden or lingering death, as their inevitable and often irremediable consequences, the sufferer runs a continual risk of being carried off by an acute attack of inflammation of some vital organ, especially of the lungs. In advanced cases, dyspnoea is a constant symptom, and this arises from some impediment to the lesser circulation. That the capillaries of the lungs, if not absolutely in a state of inflammation, are at all events in imminent risk of being so, and bronchitis along with heart-disease is a very dangerous affection. However, we may almost certainly check it by Aconite and Bryonia, and from considerable experience I would strongly advise that in such cases the strongest doses of these medicines should be given. I have frequently checked an attack by a drop of the first decimal dilution of each of these, in alternation every hour. Having now briefly adverted to the causes, symptoms, consequences, and complications of hypertrophy of the heart, let us direct our attention to the treatment of this OF THE HEAR'T. 24.7 disease. Although, as we have already said, we must season our confidence with caution, yet it is gratifying to be able to affirm that in cases of simple hypertrophy, if the valves be not affected, we may hold out to the patient a certain assurance of relief; and, if the case is not very far advanced, a considerable prospect of permanent cure. The following case, which occurred in my own practice, I have the less hesitation in relating, because hitherto, as far as I can discover, there is a great want of recorded cases of the treatment of organic diseases of the heart in homoeopathic literature. The subject of the following narrative was a lady of about sixty years of age. She was very thin, her head very large and her chest very small; she had an incessant short cough; even without a near inspection I was struck with the great size of the jugular vein, which seemed to throb like an artery. She complained of pain in the right side, and said she was, she believed, suffering from liver complaint, for which she had been treated for many years by one of the titled dignitaries of our profession, who saw her daily for many months during the previous year. On questioning her about her heart, she said that from her childhood she had been subject to dyspnoea and palpitation on any exertion, but that ever since she had undergone much mental distress by the death of her father and only brother, about fifteen years ago, she had suffered from almost constant palpitation of the heart. This had become much stronger about two years ago, when she was at Malvern. Besides constant cough, dyspnoea excited by any exertion, and a sense of beating of the heart, she was subject to intense pain in the head, chiefly the back part, but the most distressing symrntonl 248 SOME ORGANIC DISEASES of the case was that she could not lie down, and she was obliged to sleep propped up with pillows. She fell asleep in this position, but in about twenty minutes she woke with a sense of suffocation. The pulse was large, full, rapid, and irregular. On examining the chest, I found it very small in all its dimensions, and whenever the clothes were removed there was the heart visibly beating with great force over a large space of the left side. The impulse was felt as low down as the seventh rib. On applying the stethoscope I could not detect the sounds at all distinctly, but there was no abnormal murmur. I should have mentioned that besides cough she had of late frequent attacks of haemoptysis. Of course there could be no possible doubt of what the matter was. It was manifestly a case of simple hypertrophy of both ventricles, probably rather more of the right than the left. There was an increase in the size of the cavities, and of the thickness of the walls. I confess my opinion of the probability of her recovery was very small, and I looked for a fatal termination as a probable and speedy event. The disease seemed to have advanced to a stage in which cure is seldom effected. However, the result was most gratifying; by pursuing the treatment which I shall describe in the sequel slie gradually improved, and when I last saw her she was so well as to undertake a journey in a carriage to Cheltenham in one day. She could sleep for several hours in perfect tranquillity; she could lie with her head almost as low as other people; the pain had left her head; she had seldom any difficulty of breathing; and the cough was no longer troublesome. The heart was still too large, but the discomfort fi'om the violent palpi OF THE HEART. 249 tation was gone; in short, she is now not only relieved from the apprehension of speedy death, but from all the distressing symptoms from which she had suffered for many years. One of the greatest difficulties I had to encounter in the management of this case was the regulation of the diet, and as this is a point of primary importance, it may be as well to advert to the principles which must guide us in all similar cases. The patient felt very weak, and thought it necessary to sustain her strength by taking animal food twice a day and a couple of glasses of wine. It was no easy task to convince her that she would be stronger if she ate less. It is, however, quite obvious that if we wish to reduce a muscle we must stop its supply of blood as much as we can. In the cure of the heart it is doubly necessary, for not only does too profuse an allowance of blood tend directly to increase its already preternatural growth, but by adding to the weight it has to move, it compels it to make greater exertions, so that it is at once over fed and over worked; and, moreover, this superabundance of blood greatly increases the danger, both to the brain and to the lungs. It is in such cases that bloodletting is generally resorted to by the practitioners of the old school, and with much better reason and better consequences than in the majority of the instances where they employ depletion. Although I am not prepared to say that it does positive harm in such cases, at all events at first, yet I believe it to be quite unnecessary, and that by diminishing the food we shall accomplish our object more speedily and more safely than by withdrawing the pabulum vitae. We may safely limit our patients to one 250 SOME ORGANIC DISEASES" meal of animal food in the day, and it is well gradually to lessen even this, and let dinner consist chiefly of rice or vegetables, with only a flavour of meat, and we must withdraw all stimulants. This system of rigid abstinence ought to be persevered in for years, indeed most likely for life. It is here that the vast importance of a correct diagnosis shows itself, for if the palpitation be caused not by organic disease of the heart, but if it be a sympathetic condition in connection with debility, or some affection of the nervous system, such as I had occasion to speak of in the first section of this chapter, a straitened allowance of food and of stimulants so far from being beneficial, is positively injurious, and many patients are kept in great suffering by being denied their mutton chop and glass of sherry. There is no such risk, however, in cases of true hypertrophy, and we may lay it down as a well-established rule, that we should do our utmost to reduce the strength of the pulse by reducing the quantity of nourishment, and by absolutely forbidding stimulants in every form; and we shall find that the patient instead of feeling weaker, feels gradually better and stronger in consequence of this temperance. Having settled the point with our patient and obtained his concurrence to be very moderate in food, we may then open our trenches against the disease by a course of medicine, and it fortunately happens that the indications for their selection are as well marked as their effect in controlling the action of the heart and modifying its nutrition is certain, rapid, and in most cases surprisingly beneficial. Without entering upon the vexed question of how far OF THE HEART'. 25,1 hypertrophy is always preceded by inflammation, properly so called, we are, at least, safe in affirming, that the pathological state of the blood-vessels which attends active increase of growth of any part is so closely allied to the inflammatory condition, that we may securely anticipate that any medicine which has a powerful action in subduing inflammation of the heart, will afford valuable aid against hypertrophy of this organ. And no medicine has a more direct antiphlogistic operation on this disease than aconite. Were we not in possession of this invaluable remedy, we might justly be blamed for refusing to employ bloodletting, but Aconite does all the good and none of the harm of the old fashioned lancet. Professor Arnold found that on giving Aconite to a frog the beats of the heart were first increased, and then diminished to such an extent that the auricles contracted twice for every contraction of the ventricle, and an intermittent pulse was produced; and the following symptoms, which were produced in a medical student by taking 2386 drops of the tincture in the course of sixty days, read almost like an acute attack of inflammation of the heart.1 After experiencing tearing pains in the knees and elbows for several days, there commenced violent palpitation of the heart twice a day; the pains and palpitation came on in alternation; after the pains ceased a second time, violent palpitation returned, attended with anxiety and oppression of the chest, and sometimes great dyspnoea. In the famous case of the robber who was poisoned by Aconite, Mathiolus describes that, although he spoke boldly, and had a look of animation SSee Dr. Dudgeon's article on Aconite in the ' Hahnemann Materia Medica.' 252 SOME 'ORGANIC DISEASES with perfect consciousness, yet the pulse was almost imperceptible, and he complained of great weight about the heart. However, it is not necessary to multiply proofs of the fact that Aconite has a powerful effect upon the heart, and we may give it with great confidence as an intercurrent remedy in cases of hypertrophy. We naturally have recourse to Aconite when from any cause there is unusual perturbation of the heart's action from some sudden excitement, either mental or bodily. By the immediate use of Aconite we believe the life of a patient suffering from great hypertrophy may often be preserved, and we should advise that such a person should always have a supply of the 1st or 2d dilution beside him, that he may immediately apply it on any sudden emergency. Besides its value as an extinguisher of these outbursts, it may be usefully given in smaller quantities and at longer intervals, for a week or two at a time, in the course of the cure. I think we do not give Aconite its due as a deeply working medicine, and its high credit in acute diseases has unfairly thrown it into the shade in the treatment of many chronic diseases, of which hypertrophy of the heart is one. Valuable as Aconite is, there is, however, no doubt that Arsenic is of still greater importance in subduing organic diseases of the heart. Dr. Wurmb, of Vienna, an excellent authority on all practical points, observes: " We think we do not err if, relying upon our own experience at the sick bed, we maintain that a large proportion of the symptoms connected with respiration we have above described, must be ascribed to the baneful action of the poison upon the heart; though at the same time we arc far from denying that they may partly be owing OF THE HEART. 253 to an idiopathic action on the respiratory organs or spinal cord. Be this as it may, this at least is certain, that symptoms indicative of an affection of the heart gene. rally appear in a very violent degree at the commencement of poisoning by Arsenic, and are rarely absent." This fact is so well known to the old school by the excellent work on poisons by Professor Christison, that the only marvel is, how, knowing Arsenic to produce palpitation and irregularity of this organ, they can yet agree with us in prescribing it as a proper remedy for a condition in the sick which they acknowledge it produces in those who are well. From among the writers of the homoeopathic school who have directed attention to Arsenic, we may quote an observation by Dr. Black, whose authority in practical matters, like that of Dr. Wurmb, stands deservedly high: " In organic affections of the heart," he says, " especially where there is dilatation or valvular disease, it is the best remedy; and it is worthy of note, that under its use the various pains, the distressing palpitation, the dyspnoea, are relieved in a marked manner, and that while the organic change remains unchanged." As far as my experience goes, I fully concur in all that is said of the value of Arsenic in the treatment of organic diseases of the beart; not only do the pains frequently subside by the use of this medicine, but the most formidable symptom we have to contend with-the tendency to anasarca-is often arrested by a persevering admistration of this remedy. I cannot say so much for the next medicine we find generally recommended, I mean Baryta carbonica. I have tried it several times, but never saw any good done 254 SOME ORGANIC DISEASES by it; and I think a careful study of the proving will show that it is only useful in cases of sympathetic palpitation. The following are the chief heart symptoms given in Hahnemann's Cltronic Diseases: Throbbing with stitches in the left side of the chest, proceeding outwards from the pit of the stomach. Palpitation on lying on the left side. Occasional strong palpitation. Palpitation of the heart, increased by thinking of it, she then had a feeling of anxiety; chiefly after dinner." Now, in hypertrophy of the heart there is never absence of palpitation, nor is it produced by thinking of it or by eating, whereas nervous palpitation, with sympathetic relation to the stomach, especially in a female, is commonly brought on by these causes. It seems of consequence to point out this inaccuracy, as it is by such hasty inferences that serious errors become stereotyped in our practical works, by far the greater number of which consist of uncritical reproductions of the matter contained in the earlier manuals. Noack and Trinks very properly confine their recommendations of Baryta to palpitation of the heart, especially of chlorotic and hysterical females. Digitalis being the great stand-by of the old school in heart diseases, our patients have generally had enough of it before they come to us, and it is not easy to specify the exact character of the cases for which it is useful. I should say, from my own observations, that it does most good when there is great and sudden oppression of the heart with hypertrophy. But I look upon it more as an intercurrent remedy to get the patient out of an immediate embarrassment, than as one available for the radical cure of the disease. And on the whole I agree with OF THE HEART. 255 Dr. Black, when he says, " the diseases of the heart in which it is indicated are those in which the action of the organ is disordered and depressed. In simple hypertrophy, where there is increased power and energy of the heart, it is contra-indicated, but promises to be useful, especially in simple dilatation, and moderate hypertrophy with dilatation; the more so in cases where the dilatation is a primary disease dependent on deficient energy of the heart, and not on the pressure or obstruction of the circulation." Of Lachesis I do not think it necessary to speak, because I am now quite satisfied that the poison of Naja tripudians or Cobra di capello will entirely supersede its use in our future practice. It possesses this immense advantage over Lachesis, that we can get it, whereas the single drop of Lachesis launched by Dr. Hering into the homceopathic world, must in the course of time be exhausted. I do not think it is possible to exaggerate the utility of the Naja poison in the treatment of organic disease of the heart, whether of hypertrophy or of valvular affections. This was the chief remedy I employed in the case of the lady whom I described as having been rescued from apparently inevitable death. In her case there was no possibility of deception; the disease was as well marked as any disease could be, and the improvement beyond doubt or denial. Nor is this the only case. I lately treated a very bad one of valvular disease, of fifteen years' standing, and once or twice the limbs swelled to double their natural size, and were reduced by giving Naja. It seems to exert a direct action upon the heart. About two years ago I injected a grain of the poison dissolved in oil into the facial vein of a rabbit; the operation OF THE HEART. 257 by sitting down and by bending the chest forward. The anguish increases during a deep inspiration, and when arresting the breathing; he has then palpitation of the heart and oppression; the heart beats more violently and he feels the puilsations of the heart when laying the hand on the pit of the stomach." Noack and Trinks recommend it in chronic affection of the heart, particularly valvular disease, hypertrophy, and dilatation of the heart. This medicine stands by common consent at the head of our remedial list against acute carditis and pericarditis; and whenever the symptoms of a chronic organic disease assume an acute character, we may safely consider Spigelia as well indicated. We find Tobacco mentioned in this catalogue by some writers, but I think this medicine is more suitable for functional nervous affections of the heart, than for those in which there is a change of its structure. Besides having a store of what may be called sieging munitions to reduce by slow and steady operation the disease within the citadel of life, we must also be provided with means to check the sudden sallies of the enemy, which often threaten instant death. Some months ago I was sent for to see the patient whose case I have described as having been much improved by Naja, I found her bent nearly double upon the sofa, her face and lips deadly pale; although scarcely able to speak, she coma plained of a dreadful pain extending downwards towards the loins; on attempting to feel her pulse, it was almost gone, it felt like a thread, and there was great dyspnoea. I confess I expected to see her expire before my eyes. I gave her two drops of the Tincture of Camphor, every 17 258 SOME ORGANIC DISEASES five minutes, and in the course of twenty minutes she was better; under the continued use of this remedy she gradually recovered her old standing ground. In another case of great valvular disease, in which the patient is awakened at night by a sudden sense of oppression of the chest, and feels himself in the agony of death from want of breath, I have found Camphor give constant relief. Indeed, so satisfied is this gentleman of its value, that he is never at ease unless he has a bottle of it in his pocket to apply to when these paroxysms attack him, for now they do not occur only at night, but frequently during the day likewise. On these grounds, then, I can recommend Camphor as the best remedy in the sudden attacks of suffocation or paralysis of the heart, which threaten to terminate instantaneously the remains of life left to the sufferers from far advanced organic disease of that organ. PERIcARDITIS. Perhaps in the whole range of medicine there is no disease more trying to the skill, sagacity, courage, and decision of a practitioner than pericarditis; for it is obscure in its symptoms, perplexing by its complications, rapid in its course, often fatal in its termination to the life of the patient, and still more fr'equently fatal to all comfort in life. Even now, when so much has been done to facilitate its diagnosis, it often escapes detection till too late, and from many causes the most skilful treatment may prove unavailing. It is a comfort to us, however, that there is no disease in which the superiority of homoeopathic treatment is more unequivocally superior, and OF THE HEART. 259 none in which a careful study of morbid anatomy justifies us in believing that in those cases in which our efforts are unsuccessful, the cause is in the inherent impossibility of the success of any medication. The term pericarditis is applied to all inflammations of the pericardium, and these are not only very different in intensity and extent, but wholly unlike in their essential characters. The only feature in which they all agree is, that all are attended by some effusion, but the nature of the effusion in each is characteristic, and depends upon the general habit of body, which is plainly beyond the physician's control at the time he has to treat the attack. The sweeping term, pericarditis, in fact, stands for various varieties of diseases, ranging from slight and hardly dangerous inflammation attended with the secretion of absorbable lymph, to those kinds in which the discharge is haemorrhagic or albuminous, and which almost necessarily end, either directly or indirectly, in death: and hence we should be on our guard to avoid rash inferences from statistical returns, in which one name stands for many very different things. In the first and inost common variety there is an effusion of lymph upon the naturally smooth opposite surfaces of the enveloping membrane of the heart. On examination, it resembles butter in colour and consistence, and when the two surfaces are separated, by its partial adhesion it is raised, so as to look like the pile of velvet; and hence, a heart so affected was called by the old writers " cor villosum, hispidum, hirsutum;" and in the ante-phrenological era of creation, was assumed to indicate an irrepressible disposition to robbery, murderi and enormities of that sort 260 SOME ORGANIC DISEASES -doing duty for modern " destructiveness." However, the connection of this villous state of the heart and villany of character is not now generally believed, and it chiefly interests us on historical grounds. This variety of deposit upon the surface of the pericardium is capable of speedy resorption, and may end in perfect recovery. It may, however, instead of being absorbed, undergo a series of transformations, becoming organized, either fully or partially, and ending either in a perfect cellular tissue with independent blood-vessels, or in so-called ossification, although the hard substance into which it is generally converted is not bone, but merely a form of lime. This process of development, consisting of the formation of elementary corpuscles, always begins within four days from the time the deposit has taken place, and distinct cells, from which a whole organized body proceeds, are discernible on the fourteenth day. After this false membrane is once fully formed, it becomes as much a part of the body as one of its natural members, and bids defiance to all art to remove it. All we can do is to lessen the mischief its presence inflicts upon the heart: the worst of this is that it partially paralyses the muscular fibres of the heart with which it comes in contact, and thus gives rise to the hypertrophy and irregularity which we had occasion to speak of before, and ivhich are often erroneously attributed to the bands of lymph restraining the natural action of the heart's action. This mechanical explanation is only partially correct, the more common cause of derangement being the vital one just adverted to. When the development of the membrane is arrested, and when it is converted into a firm calcareous unvascular substance, then it does less harm apparently, and OF THE HEART. 261 merely interferes mechanically with the free movements of the heart. Instead of fibrinous the deposit may be albuminous, and this, being the matrix of tubercle, is much more dangerous. Albumen may be changed into pus or tuberculous matter, but is not susceptible of healthy organization, so that again we encounter an insurmountable obstacle to recovery or cure. The albuminous deposit takes place when the blood is in what the German writers call the albuminous crasis, and is said by Zehetmayer, of Vienna, who is one of the best authorities on this subject, to be met with most frequently in children, during the progress of some acute exanthematous disease, when the course of this is anomalous; during the typhous process; in acute cases of Bright's disease of the kidneys; and in drunkards, whose blood has not got so low as to present the scorbutic character. Next in order stands the serous effusion; this is sometimes very great, it may be seven or eight pounds, and it is met with when there is from any cause much poverty of the blood. It is usually attended with dropsical effusion into the other cavities, and is, both in itself, and from its inevitable consequences in displacing and oppressing the heart and lungs, a very bad form of the disease. Lastly there is the haemorrhagic effusion, the worst of all, indicating a pronounced dyscrasia of the whole system, for it is only possible when there is a general tendency to dissolution of the blood, and attends diseases of a so-called putrid character, in which the presence of petechiae, and the ready formation of pus, indicate the hopeless degeneration of the mass of the blood, which is then converted from vital food to a 262 SOME ORGANIC DISEASES mortal poison. Such are the chief primary results of inflammation of the pericardium; upon the secondary, which are also most important, we must here refrain from entering. As might be expected when an organ of such paramount importance to life as the heart is overwhelmed by sudden and severe disease, the most characteristic feature of the case is the general expression of mortal suffering exhibited by the patient. The face is pale and pinched, frequently the features are contorted and spasmodically contracted, as in chorea, owing probably to the sympathy between the heart and countenance, maintained by the pneumogastric nerve; the pulse is rapid, and generally irregular; the patient cannot lie on his left side, but only on the back, or he cannot recline at all, but sits up and bends forward, and may even be obliged to seek relief by supporting himself on his hands and knees; the respiration is hurried and often attended with pain. There is also always more or less pain at the region of the heart, frequently sharp and violent, and increased by pressure; on laying the hand upon that place the heart is felt beating tumultuously and irregularly; in cases where there is little effusion the action is powerful, but this is subdued by much fluid in the pericardium; then instead of this sign we have extended dulness. On applying the stethoscope, a rubbing sound is heard, not exactly synchronous with the sounds of the heart, but lingering behind these, and this is the diagnostic difference between pericarditis and inflammation of the interior of the heart; this friction sound is plainer when the patient holds his breath for a moment, and by this experiment we exclude the friction sound being due to pleuritis. When such a 264 SOME ORGANIC DISEASES provement, and he was bled again and again the next day. On the fourth day, in spite of the four previous bleedings, the joints on the left side were red, swollen, and painful: twenty leeches were applied to the knee. On the fifth day there was no change. On the sixth day he was bled a fifth time, and a dozen leeches applied. During the day, he seemed to be much better, the redness, pain, and swelling of the joints subsided; at six in the evening the pain was entirely gone." What a testimony in favour of bloodletting, had he gone on to convalescence, but, alas! his improvement only lasted four hours, for " at ten o'clock he was suddenly attacked with a violent pain in his left side:" it continued all night, and in the morning we find the patient in the following state. " He was screaming from pain about the region of the heart; the pain was not increased by pressure, by cough, or by respiration or change of position; the joints were quite painless. There was no abnormal sound connected with the respiratory organs. The beats of the heart were frequent, tumultuous, irregular, and intermittent. The pulse corresponded in character with the heart, it was small, and disappeared under the finger. The face was pale, pinched, and expressed the utmost anxiety. The extremities were cold. The patient appeared so weak that it was not thought prudent to bleed him again. Thirty leeches were applied to the precordial region, and sinapisms to the limbs, but all was unavailing, and the patient died that evening, just twenty-nine hours after the invasion of the pain at the heart. On examination after death, the whole internal surface of the pericardium was covered with a soft and yellow membranous exudation, and the pericardium OF THE HEART. 265 itself was of a bright red colour. There was no effusion in its interior. All the other organs were perfectly healthy." It is impossible to read this remarkable case without being haunted by the reflection, of how far the remedies employed were beneficial or injurious. That at the best they were powerless, is plain enough, and knowing as we do the wonderful effect of Aconite in such inflammatory attacks, we cannot but think, that had Andral, instead of lending his powerful name to the slovenly and stupid experiments on homoeopathy made in his wards, given a fair trial to our medicines, even in so acute an attack as this, he might have had the satisfaction of saving his patient's life, instead of merely ascertaining the correctness of his diagnosis. I cannot resist the temptation of quoting, in contrast to the fatal success of the renowned Andral, the following case, which was treated about twelve years ago by Dr. Drysdale, at a time when he was only beginning to put to the test of personal experience the system which Andral so haughtily rejected. "N. J., aet. 14, of lymphatic-sanguine temperament. Five years ago had a severe fall on the head, since which time has been subject to nervousness and irritability of the heart. Five months ago had an attack of pericarditis, for which he was bled to a considerable extent, and otherwise allopathically treated; he recovered, however, according to report, perfectly, except that he has since been liable to short breathing and palpitation on running fast, but only then. About two months ago he had another similar attack, for which he was treated in the same way; the local symptoms were subdued, but 266 "SOME ORGANIC DISEASES the general health and strength had not been completely restored. 12th April, 1842.-Yesterday he was seized with shivering alternating with heat; pain in the region of the heart; quick pulse, &c. These symptoms continued to increase till I saw him: he had received three doses of Aconite 6. The symptoms observed by me were, violent pains in the region of the apex of the heart, stretching through to the back and up to the left shoulder; tenderness on pressure over the apex of the heart; action of the heart irregular; pulse hard and jarring, ranging from 126 to 140; great oppression of breathing, respiration rapid and anxious; rheumatic pains in the knees without swelling; skin hot and dry; much thirst; tongue furred; urine high coloured and scanty; great restlessness. Physical signs.-Rubbing sound heard at the base of the heart, chiefly along with the second sound; bellowssound in the left ventricle at the first sound (this was so marked that it most probably was the effect of structural change remaining from the previous attacks, in which the endocardium had been likewise affected). Prescription-Aconite 3d dil. dissolved in water, and a dose given every three hours. 13th.-Has passed a very restless night, and, as reported, had no sleep at all; could not lie in one position for any length of time, but was constantly tossing about; was obliged to have the shoulders raised high in bed. Great thirst; the pain in the heart greater, and more felt internally between the sternum and scapulae, and towards the left; anxiety and dislike to be left alone; since OF THE HEART. 267 morning is quieter; less heat of skin; some perspiration; pulse 126, but not hard; less dyspnoea; bowels opened once. Spigelia, 9th dil. Bryonia, 3d dil. alternately, a dose every three hours. 14th.-Better in every respect; slept a good deal; pulse still 126, but quite soft and regular; pain at the apex of the heart gone; less pain in the left side of the chest, but a good deal of pain felt in the right shoulder and pectoral muscle. Physical signs the same, and in addition some increased dulness on percussion over the region of the heart. Continue Spigelia 3, and Bryonia 3, alternately every three hours. 16th.-Much improved; pulse 98, soft; no pain in the left side of the chest; some pain in the right pectoral muscle; urine scanty and high coloured; perspiration; tongue foul; no appetite; no stool. Physical signs the same, but the rubbing sound no longer heard. Mercury 2, and Spigelia 3, alternately every three hours. 18th.-Pulse 70; symptoms nearly all gone; convalescent. A few doses of Nux vomica, Arsenic, and Digitalis restored him within eight or ten days to perfect health, except that the bellows-sound in the left ventricle at the systole remained the same as (it most probably was) before this attack." By far the most important remedy in this as in so 268 SOME ORGANIC DISEASES many other acute inflammatory affections, is Aconite. The following description of the effects of a large dose, given by a medical student, and published in the 'Austrian Homoeopathic Journal,' reads almost like a case of pericarditis. "Tearing in the legs, knees, and arms for several days, then cessation of these pains and violent palpitations in place of them, that came on at 3, 8, p.m. Two days afterwards, the tearing pains in the limbs recurred, and the palpitation ceased. The next two days the palpitation recurred with feelings of tight.. ness on the chest, the limbs keeping free from pain. The palpitation continued to increase, and was accompanied with great anxiety and oppression of the chest, and sometimes great dyspnoea." With the exception of the case I have quoted, I find few examples of unequivocal pericarditis in our literature. There is one published by Rothansel, in the Hygea, as pericarditis, but from the presence of a bellows-sound during the systole, and the absence of friction-sound and irregularity of the pulse, I am inclined to look upon it as endocarditis rather than pericarditis. Of the cases published in the Brit. Journ. of Horn. by Dr. Laurie, in 1847, in No. 1, besides other deficiencies, there was "total abscence of pain in the region of the heart." No. 2 is certainly a very puzzling case, and probably there was some inflammation of themembranes of the heart, but as the pain in the side was much aggravated by breathing, I am disposed to regard it rather as a case of pleurisy with cardiac complication. The medicines employed by Dr. Laurie were Lachesis, Arsenic, and Colchicum, and most benefit is attributed to the last. No. 3 is much the best marked of the lot. In this there was loud friction-sound over the OF THE HEART. 269 cardiac region, strong, and very abrupt impulse; there was also a grating murmur with the sounds of the heart; the expression of the face was painfully anxious; there was great restlessness; a full, strong, rapid, and regular pulse. These symptoms supervening in a lad of fifteen upon an attack of acute rheumatism, may be considered as establishing the case to be one of pericarditis. The medicines employed were Aconite and Spigelia till the acute symptoms subsided, and then Arsenicum and Lachesis till the convalescence of the patient. I have again to regret the great dearth of well-described cases of acute disease in our literature; the deficiency must be a source of much anxiety to young practitioners who have to encounter dangerous attacks of such dreadfully rapid and distressing affections as those of the heart, surrounded by opponents eager to catch them tripping, and by the incredulous and often officious relatives of the patient. Next to Aconite we come to Arsenicum as a most important remedy in this affection, and as a rule it may be selected in preference to all others, in that form of pericarditis attended with effusion of serum into the cavity, while Aconite is preferable for cases characterised by the preponderance of fibrinous depositions. Of Bryonia it is difficult to speak with confidence. Certainly there is nothing in the proving of that medicine which coincides with the symptoms of pericarditis; this, however, may be in part owing to such symptoms being masked by its action on the adjacent pleurae. It is said, by Professor Zlatarovich, to produce injection of the pericardium and redness of the heart in animals poisoned by it; but we all know how fallacious such appearances 270 SOME ORGANIC DISEASES are. On the whole I should be inclined to reserve Bryonia for cases complicated with pleuritic inflammation. Nor do I see any proof of Lachesis or Naja being suitable for the acute stage of inflammation of the heart or its membranes, although I believe theyare of immensevalue in treating the consequences of these affections. I have at present under my care an elderly lady, who has had pericarditis at some former period, which has entirely wrecked her health. The action of the heart is strong, irregular, and tumultuous, but not attended with any abnormal sound, nor is it much increased in size; she suffers constant pain in the cardiac region, and is subject to severe headache with dreadful depression of spirits, almost to the extent of true melancholia. In this case I have found great benefit from the Naja, and I have given it for months at a time without any bad consequences, and steady relief of all her sufferings. The only other remedy on which I would place reliance in such cases is Spigelia. The relation of this powerful medicine to the heart is so well marked and so universally acknowledged, that it is not necessary to enlarge upon its suitability. In the few cases of pericarditis I have treated, it has done all that medicine could do, and I have the utmost confidence in it, and I would give it alternately with Aconite every hour or two hours, according to circumstances, and in the first dilution, in cases of acute pericarditis. It is a singular thing and worth noticing, that in the proving of Spigelia by Hahnemann himself, there is no indication of its having any effect upon his heart. This shows that to determine the qualities of medicines, we must submit them to experiment on the OF THE HEART. 271 persons of many individuals, for the most important indications may not appear when tested by the best observers, if they happen not to be susceptible to the action of the substance; and we should from this learn not to disallow a medicine on account of merely negative evidence brought against it by experiments on healthy subjects. How far we should trust to Mercury is rather a difficult question. There is nothing in its pathogenesis warranting great confidence in its power over inflammation of the pericardium, but knowing as we do its great value in affections of a similar character of other serous membranes, and having the strong assurances of the best observers of the old school as to its value in checking the plastic exudation, or hastening its absorption, I should feel strongly disposed to place it after Aconite and Spigelia in acute pericarditis of robust subjects; and I would venture upon the general observation that without letting down our testimony in favour of the absolute necessity of the proving of medicines, and the general sufficiency of the homoeopathic law, yet it is quite manifest that not only Hahnemann but all the most successful practitioners among his followers, are always keenly alive to the importance of remedies, which have been tested and approved by empirical practice.1 The only auxiliary which it is well to employ in treating this disease is cold water applications over the region of 1 Since this was written, I have found Mercurius most useful in two cases of pericarditis which I have met with in practice; the one occurred in a gentleman about thirty years of age, and was complicated with rheumatism and pneumonia, he recovered perfectly in about a fortnight; the other in a young lady of about fifteen years of age, in whom it was uncomplicated, and who made a surprisingly rapid recovery. 272 SOME ORGANIC DISEASES the heart, and even these are not applicable after the first two or three days; at a later period there is a danger of these lowering the vitality of the heart too much. Acute endocarditis presents so many points of resemblance, both in its symptoms and treatment, to pericarditis, that it is not necessary to recapitulate the diagnostic signs or the remedial appliances common to both. Suffice it to say, that one of the most distinctive differences is absence of pain, and this suggests the extreme care which should be taken by the practitioner to ascertain the existence of this insidious disease, which, susceptible as it is of rapid and speedy cure if recognised at once, if overlooked, lays the foundation for those dreadful morbid alterations of the valves, which once established, generally remain for life a source of constant discomfort and anxiety, and ultimately of sudden and premature death. In the tenth volume of the Brit. Jour. of Horn., Dr. Acworth has published a most instructive example of this, where the disease was not recognised till medical aid was too late and unavailing. The following case, published by Dr. Huber, is a good illustration of the successful treatment of endocarditis, Franz. Rad., ret. 19, a weaver, feeble, of sanguine temperament, has been free from disease since he was a child. Three weeks ago he was affected, without known cause, with shivering, then heat, violent shootings in the right side of the chest, and strong palpitation and dyspnoea. He thinks he must have been working too hard. The shooting pains in the right side diminished in the course of these three weeks, but the dyspnoea and beating of the heart increased so much as to keep him OF THE HEART. 273 from his work, and he began to cough and spit up, but only for a few days. Feb. 21st.-Present state of the patient: Head free from pain; yesterday evening epistaxis from right nostril; tongue clean; much thirst; natural appetite and taste; the pit of the stomach and region of the liver are rather tender on pressure; faeces and urine normal: no cough; heavy oppression of the chest; difficulty in breathing; shooting pain in the right side of the chest when lying on that side; constant palpitation, with anxiety; weight on the heart; making him sigh frequently. On percussion, the dead sound indicating the subjacent texture of the heart was found, on one side as far as the middle of the sternum, and on the other side over an unusual extent of the left side of the thorax. The impulse of the heart was very strong indeed, striking against the ear with violence; in the left ventricle, instead of the usual sounds, there were blowing and rasping sounds accompanying both the systole and diastole. The sound which was heard with the diastole was particularly loud over the aortic valves, and was distinguishable, with diminished intensity, however, along its arch. The sound heard over the pulmonic valves was particularly sharp. The skin was dry and hot; pulse much accelerated, beating 100 in a minute, full, strong, and bounding against the finger; sleep disturbed by frequent crying out; very-anxious, timorous state of mind. Treatment-Aconite 1, a drop every two hours in water. In the night of the 21st February, he had the first good -night's sleep he had enjoyed for some time. On the morning of the 22d, the impulse of the heart was felt 18 274 SOME ORGANIC DISEASES. to be much less, and does not lift the ear during auscultation. In the afternoon his nose bled a little; auscultatory signs as they were. Night's sleep good. Feb. 23d,-Much the same; treatment the same. All night the patient slept peaceably, and perspired strongly. Feb. 24th.-The heart-stroke is much softer, and abated in strength; at night sweating and good sleep. Feb. 26th.-No change of any kind. Feb. 27th.-He has nothing to complain of; the breathing, action of the heart, and pulse, are quite natural. The noise over the aortic valves is gone; there is only a little blowing murmur still heard over the mitral valve during the ventricular systole, but much feebler than before. The skin is cool, and all the functions normally performed. The same medicine was continued. March 2d.-The mitral murmur'has also disappeared over the left ventricle; the clicking sound accompanying both movements of the heart might be distinctly heard. The valves acted perfectly. The patient is beginning to be hungry again. The medicine continued. March 3d.-On percussion, I found the dull sound over the heart to be of normal extent. No medicine. In four days more the patient was well enough to resume work. This was probably a case of inflammation of the serous membrane which lines the heart, and forms by its reduplication and combination with the fibrous tissue the valves of that organ; and the cause of the murmurs in this and similar cases may be owing to a partial paralysis of the muscles by which these valves are stretched, for OF TnHE HEART. 275 we know that this is a common effect of inflammation in contact with muscular fibre. If this be the true explanation, it is easy to understand the rapidity of the cure, and it disposes of the assertion of some able writers that endocarditis once established must go on to permanent alteration in the structure of the valves. True, if the inflammatory process involve the fibrous as well as the serous tissue, and there induces a deposit of calcareous matter, or an organized metamorphosis into true cartilage or bone, in such a case the structural change in the valve is necessarily permanent and irremediable. But this is by no means a necessary, although a very frequent termination of endocarditis, and it is of the utmost importance to detect this affection and treat it vigorously in time, so as to prevent this dreadful catastrophe. By far the greatest number of true heartdiseases depend upon this cause. The inflammatory action once set up in the lining membrane, extends over its whole surface, and the fine margins of the valves are converted into hard edges; the whole valve is contracted and unable to prevent the return of the blood from the vessel or cavity whence it comes, and thus the progress of the current is partially arrested, and all the dismal consequences of derangement of the entire circulation ensue. Modern science has done much to enable us to detect with almost unerring certainty the nature of lesions of this kind, and it is of importance, both in reference to prognosis and treatment, to be exact in determining the particular valve affected. As a general rule, the valves on the left side of the heart undergo organic changes twenty times more frequently than those of the right, whether owing to the 276 SOME ORGANIC DISEASES great muscular strength of that side, the greater irregularity of the general as compared to the pulmonary circulation, or the quality of the blood, or a combination of all these causes, has not yet been ascertained. Suffice it that such is the fact, and that in nineteen cases out of twenty where we find some organic disease in the heart it begins in the left side. The mitral valve is most commonly at fault. In disease of this valve the pulse is almost always small and irregular, and when we find a small and irregular pulse, combined with a preternaturally powerful impulse over the region of the heart, we may almost certainly assume that this is owing to disease of the mitral valve. On applying the stethoscope to the region of the heart, instead of the teek-tak of health, we hear a confused blowing sound. There are various varieties of these murmurs, but it seems an over refinement to classify them; for all practical purposes it is enough to ascertain that they arise from some organic change, and are not merely functional. In certain anmmic states of the system the blowing is heard, but the test by which we distinguish these from organic sounds is a very simple one. If the blowing be from the state of the blood, as in chlorosis, then it is loudest in the arteries, and becomes fainter as we approach the heart; the reverse is the case if it arises fr-om organic disease of that organ. Besides, the pulse of anamia is soft, while the pulse of mitral disease is sharp and jerking, indeed so peculiar that, after it has been felt once or twice, it can hardly be mistaken. Disease of the mitral valve, if moderate in degree and not attended with hypertrophy of the heart, may go on for many years without materially affecting the health of OF THE HEART. 277 the person. There are examples of men living to 70, and even 80, with this affection. If there is hypertrophy, which is the natural consequence of imperfection of this valve, then the -chances are much worse, and the health is. always impaired and the life generally shortened. Hence the immense importance of judicious treatment in this class of affections, so that the consequences of an irreparable injury may be delayed as long as possible. Sometimes there is no pain, although there is great organic disease, but this is the exception, and as a general rule, when the valves are affected, there is violent stabbing pain felt frequently in the heart. It is not easy to account for the severity of the pain, and I feel disposed to attribute it to spasm of the muscles, for it is of a spasmodic character, both in its severity, uncertainty, and duration. I have seen it cured permanently by Lachesis and I have great confidence in this and Naja in relieving the sufferings from disease of the mitral valve. I had under my care a gentleman who had suffered for 15 years from this complaint. There was very great irregularity of the pulse, which was like a thread, with violent action of the heart; he suffered dreadful pain at the heart, and the limbs often swelled. He found relief from Naja continued for some months; and it is a curious fact that he should derive benefit from homoeopathic medicines at all, for he takes a wine glassful of Laudanum every day. He has done so for many years, and will not or cannot leave it off. Once he tried to leave it off, but the most dreadful diarrhoea set in, and nothing checked it till he resumed his laudanum. Of course we must take patients as we find them, and we cannot refuse a case because the patient has a bad habit 278 SOME ORGANIC DISEASES which he cannot check. I certainly did not expect that the homoeopathic medicines would do so much as they have done in this case. Insufficiency of the mitral valve implies regurgitation of the blood from the left ventricle into the left auricle, and hence there is an obstacle continually presented to the free discharge of the contents of the pulmonary vein. The consequence of this is obviously a state of repletion of the lungs and a constant risk of cedema of these organs; and as the blood can no longer pass freely through the lungs it is not sufficiently arterialized, but retains more or less of its venous character. Hence we find a tendency to venous congestion of various organs, and especially of the liver. It is a most important discovery of modern pathology that this supervenosity of the blood is incompatible with the formation or growth of tubercle, and whenever we find disease of the heart of such long standing and of such a nature as to produce this state of the blood, we may be quite certain that tubercular phthisis cannot exist, or if it exists, that the process of the development of the tubercles is cut short. Rokitansky was the first to direct attention to this important fact, and I have frequently found a knowledge of it of great service in cases of difficult diagnosis. Any state of the system in which the blood is venous gives the same immunity, even curvature of the spine when it is so great as to impede the movements of the chest. And as it is sometimes difficult to distinguish spinal curvature and irritation, attended with cough, pain, and hkemoptysis, from phthisis, this fact is of great diagnostic value. I have known a case treated by the most celebrated physicians of the old school as phthisis, for years, OF THE HEART. 279 which I was able confidently to declare to be free from all tubercular disease on the strength of this observation, and the course of the cure justified the confidence. Next in frequency to disease of the mitral valve is disease of the semilunar at the orifice of the aorta. When, this exists it is generally attended with a small and intermittent pulse, but not so irregular as in mitral disease. The blowing noise may attend only the first systolic sound of the heart, if the margins of the valve are only rough; if, however, there is imperfect closure, there is a murmur heard during the heart's dilatation, as well as during its contraction, from the regurgitation of the blood into the left ventricle. It is important to know that recent pathological investigations have established the fact that this form of disease is very frequently associated with an albuminous state of the urine, and we should be on the watch for this complication, as, of course, it impairs the chance of the patient's restoration, and will modify both our prognosis and treatment. We are indebted for this observation to Dr. Hammernjk of Prague. Insufficiency of the tricuspid valve is very rare, and when present can be readily detected by the pulsations in the gorged jugular vein being synchronous with the contractions of the heart and arterial pulse. It is almost always combined with disease of the mitral valve, hypertrophy, and other organic changes, which preclude any hope of recovery. In regard to the treatment of organic valvular diseases of the heart we must be content with very vague and general directions. We do not know, nor are we likely ever to discover, the finer relationships of the medicines 280 SOME ORGANIC DISEASES to the tissues of the heart, for it is not to be expected that experiments will ever be pushed so far as to induce irremediable mischief to the experimenter; and very serious changes may go on in the structure of the heart without any definite sensations by which they can be recognised by the sufferer. It is however very satisfactory to know that much relief may be given by homceopathic medicines, especially Aconite, Arsenic, Lachesis, Naja, and Spigelia. I have at present under my care a case of aneurism of the arch of the aorta. The first thing that directed my attention to the seat of the disease was the preternatural strength of the pulsations of the carotid artery. On examining the heart I could find no material enlargement, but there was a peculiar sound over the top of the sternum, and a sense of weight there, with difficulty of breathing on making any exertion, or on lying down. Dr. Black, who saw the case with me in consultation, concurred in the diagnosis, which the issue of the case confirmed. The medicine which seemed to me to give most relief here was Digitalis, given in doses of two or three drops of the first decimal dilution daily. Of course in such a case cure is out of the question, but it is well to know that even in these incurable cases relief may be given by such doses of medicine as we are in the habit of employing, and I have little doubt that the life of this patient was prolonged by steady perseverance in homceopathic treatment. On the whole, to conclude these desultory remarks upon diseases of the heart, we may safely say that if we take the trouble to master the diagnostic rules laid down by allopathic writers, and to attend to their directions on matters of diet and regimen, we may be able to surpass OF THE HEART. 281 them immeasurably, both in the cure of those inorganic and troublesome affections of the heart, and of all the curable organic ones; and that when we too are compelled to deplore our inability to hold out hopes of restoration to health, yet even in the vestibule of death we may do much more than they to mitigate the sufferings we cannot remove, and to tranquillize and prolong the life we cannot save, without resorting to those baneful drugs which give immunity to pain only by stupifying the senses, deranging the intellect, and extinguishing the affections. CHAPTER VI. ON PNEUMONIA. BEFORE entering on the immediate subject of this paper, we think it may be well to make some general observations on the relation of Homceopathy to Pathology. Homceopathy may be defined the law of relation between morbid action and the external specific forces of nature. The relation is one of similarity and antagonism; its perfect application implies two knowledges, frst, the knowledge of all the morbid actions which are liable to arise spontaneously in the animal economy; second, the knowledge of the effects of all specific forces in producing morbid action. The latter kind of knowledge embraces all that refers to the proving of medicines, and is not now relevant. Without going into any wire-drawn metaphysical disquisitions about what we mean by knowing morbid action, we may state generally that we look* upon this knowledge as of the same kind as that by which we recognise a person. The more intimate we are with anyone, the more slight need be his indication-his footstep, his PNEUMONrA. 283 knock, the most distant glimpse of his figure are enough to identify him beyond all doubt in our mind. If we were asked to state scientifically how we so recognised him, we might say, we perceived with a rapidity almost intuitive all the differentia between him and every other individual. Could we abstract these differentia in imagination, they would become "his mark"-we may say his symptom-not him. The qualities of mind required for this simple process are of two kinds, the observational faculty and the imaginative, using the latter term in a large sense. Isaac Taylor remarks in his work on "Home Education,' that nothing shows the difference between man and the lower animals so well as the effect of a picture upon a dog and a child. It is the highest compliment to a painter when a dog recognises the likeness of his master: the dog requires a full representation of the object; but take a piece of chalk and draw anything like an upright, forked animal, with a hat on the head, and immediately a child exclaims "papa!" The child's imagination " bodies forth the forms of things unseen." So it is with a physician. Disease is the total differentia from health superimposed upon an individual; the physician of the highest order knows the relation of all the members of the morbid group; if he observe the presence of one he is sure of all the rest, as Cuvier was of all the bones of a skeleton, from a single articulation. To accomplish this great feat of art, he requires as thorough a knowledge of all morbid processes as Cuvier had of anatomy; and more than this, he requires the high faculty of imagination, or the power of successful hypothesis. "The bodying forth" (to return to the phrase of him who knew the process better than 284 PNEUMONIA. any man that ever lived) is a work of the higher reflective and imaginative rather than the lower observing faculties; the faculties which relate us to the Creator as contrasted with those which relate us to the creaturethe God-like as opposed to the sensuous. Herein lies the explanation of a fact which we have often observed but never heard accounted for-that all great physicians have been distinguished more by their reflective than their observing faculties. Let our readers recall the cerebral development of those who have taken the highest place in medicine, and observe whether the upper or reflective. region does not immensely preponderate over the lower or observing. Take Hippocrates, Galen, Hahnemann, Abercrombie, as examples.' I It is not necessary to assume the truth of phrenology to gain consent to the proposition, that a well-developed upper part of the forehead is never absent in those gifted with high reflective powers. The testimony of all ages, from Plato to Coleridge, "the wrapt one of the God-like forehead," as Wordsworth calls him, is uniform upon this point, nor is it necessary to prove the genuineness of the likenesses of Hippocrates; it is more important for us to know what kind of head the Greek artists attributed to the father of medicine than to know what lie actually had. The following anecdote is told of Dr. Abercrombie, in a delightful article upon Locke and Sydenham, which appeared in the 'North British Review,' some years ago:-" The doctor sauntered into the reom in his odd, indifferent way, which many must recollect, scrutinized all the curiosities on the mantelpiece, and then, as if by chance, found himself by the patient's bedside; but when there his eye settled on him intenselyhis whole mind was busily at work. He asked him a few plain questions, spoke with great kindness, but very briefly; and coming back to consult lie said, to the astonishment of the surgeon and young student (who had been treating the patient for malignant disease of the stomach), 'His mischief is all in the brain; the stomach is affected merely through it. The case will do no good; he will get blind, convulsed, and die.' He then in his considerate, simple way, went over what might be done to palliate suffering and prolong life. He was right; the man died as he said, the 286 PNEUMONIA. individuality, but he must realise to some extent the effects of such disease upon his patient. To enter fully into this would lead us to consider the moral attributes required for a physician, and this would be quite beyond the scope of these introductory remarks. Suffice it to say, that the place of a practical art in the intellectual scale is fixed by the amount of thought required for its development, and its place in the moral by the amount of feeling required for its exercise; and that the art of healing occupies the highest place in both, the power of "healing all manner of diseases" being the natural attendant of that inward purity which dwelt as light in the Physician of souls. So much for the absolute necessity of.a pathology to every medical practitioner. In passing from these general observations of the necessity of pathology to a homoeopathist to the consideration of the subject immediately before us, we may observe, that the speed and certainty of a cure of any acute disease, is in the inverse ratio of the extent of the lesion, and the direct ratio of the amount of expression of the changes. In neuralgia, for example, we have the minimum of derangement of structure, and the maximum of sensation; because the parts are in the most concentrated form, and 'are the seat of sensibility, and of no disease is the cure so quick, perfect, and permanent as of some cases of idiopathic " tic doulouroux." All homceopathic practitioners must have met with such cases; we remember two especially which occurred in our own practice, they were both of long standing, the one patient had suffered almost constantly for years, and both were cured by a few doses of medicine, and never had any return of the complaint. The reason for our success PNEUMONIA. 287 in such cases is obvious: in all the " algias," as the name implies, te paini is tze disease. As in Zeuxis' famous painting, the curtain was the picture. Morbid anatomy gives no additional information, the whole disease is expressed, in its most exaggerated form, by the sufferings. All we have to do is'to find out a similar picture of pain in some of the observed effects of a drug, and as certainly as a wave of sound, when rolling along its aerial course, is brought to rest and silence by meeting with one exactly equal and similar proceeding in the opposite direction,1 so certainly will the entire flame of pain, though it may have been burning for years, be extinguished for ever by the application of the specific remedy. The farther we recede from this point, that is the larger the lesion and the smaller its expression, the more difficult and tedious, though not necessarily the less certain (for reasons which will appear in the sequel) will be the treatment of the disease. And, as we may put toothache at one end of the scale, we may put pneumonia at the other, for here we have, in some instances, a most extensive lesion of a most important organ taking place without any sensible expression whatever. For example, Grisolle says" I shall never forget the history of an old woman in the Salp6triere, who, in the month of May, 1831, presented herself for consultation; she was ordered a laxative to restore her appetite, which she had lost for a day or two. This woman, who bore no trace of any serious disorder, nor otherwise complained of any pain, had no 1 See a very well-written paper in a recent number of the ' Household Words,' entitled "Chemical Contradictions," in which homceopathy is spoken of. Who would have dreamt ten years ago of finding homceopathy among the Household Words of England? 288 PNEUMONIA. heat of skin; her pulse was slightly frequent and irregular, which might be explained by an old heart-affection. This woman still took her food, in the course of the day made several turns up and down the court, and, towards the close of the day, she sat down and suddenly died (elle s'assit et mourut subitement)." 1 It is not easy to exaggerate the importance of pneumonia to the practical physician. Next to typhus fever it is, according to Dr. Farr,2 the most deadly disease in Britain. One out of every twenty-five deaths is owing to this disease; so far from an attack giving immunity for the future, as is the case more or less with typhus fever, it is its own most prominent predisposing cause. Out of 175 patients ill of pneumonia, questioned by Grisolle, fifty-four had previously been affected with the disease. Chomel3 attended a patient in his tenth attack; and Rush mentions a German, in Philadelphia, who had had twenty-eight attacks of the disease.' Not only is it a frequent and fatal disease, but it is one which can be recognised by a skilful physician with infallible certainty, and of which we know aý much as it is possible to know of any disease, and it is one in which the difference of I ' Traite pratique de la pneumonie aux diff6rens ages et dans ses rapports avec les autres maladies aigues et chroniques,' par A. Grisolle, D.M.P., p. 435. As this is the first time we have had occasion to refer to Grisolle, we may mention that he is recognised as the aulhority in pneumonia; and, as we shall have frequent occasion to quote from his work in the sequel, it is well to know that Louis, and all the highest authorities in France, Germany, and Britain, regard Mons. Grisolle as perfectly trustworthy. SReport of Annual Mortality. SDiction. de MId., vol. xvii, p. 214. 4Cyclopted. of Pract. Med., vol. iii, p. 406. PNEUMONIA. 289 success in the application of medicine seems commensurate with the skill exhibited in the choice of the remedy, and the timeliness of its administration. Thus the difference of the mortality, under the most approved allopathic and homoeopathic treatment, is enormous; and it is quite within the sphere of legitimate expectation, that in proper hands and under favorable circumstances, all cases of simple pneumonia will be cured with almost absolute certainty. We do not propose to enter into a consideration of the amtiology or symptomatology of the disease, for, to do them justice, would require a volume, not a section of a paper; but observing, en passant, that long-continued exposure to intense cold seems the great exciting cause of the disease, we shall proceed at once to the structural changes of the part which is the seat of the disease, as, from these, in this instance, we can deduce both the symptoms and the remedy. To have a precise idea of what inflammation of the lungs is, we must first thoroughly understand the anatomical and physiological relations of the lungs; and, secondly, be acquainted with certain general facts regarding inflammation; and, at the risk of seeming both tedious and pedantic, we shall make a general survey of both these subjects. The lobes of the lungs, viewed anatomically, have been compared to cauliflower, consisting, as they do, of a main stem, branching out into numerous small offshoots, which end in blunt extremities, like minute sausages. These stems are hollow air-tubes of elastic tissue, with cartilaginous rings to support it, the rings becoming plates towards the termination of the little branches, to 19 290 PNEUMONIA. enable them to contract and dilate with the entrance and exit of air. All round these little blunt branches cluster innumerable blood-vessels, which unite with one another at every point, so as to make an inextricable mesh of net-work.1 Physiologically, the lungs connect the blood within to the air without. Here the blood is made. Blood consists of a fluid in which blood-globules swim. This fluid contains a definite quantity of fibrine, and the proportion of fibrine to globules is a matter of much importance in a pathological point of view, and to it we shall have frequent occasion to revert. Blood-globules consist of a central kernel or mass, having many of the properties of fibrine, and round this there is a capsule which enlarges and contracts, and undergoes a process of development and death apparently. According to the most recent observations, the most probable explanation of the way blood is made is this. In the chyle are small globules; these chyle or-lymphglobules, on entering the lungs by the pulmonary vein, become endowed with a highly organized covering, which probably has the power of secreting colouring matter and the other secreted constituents of a true blood-globule. This blood-globule once made, enjoys a sort of independent vitality, and reacts with different agents like a living being.2 Simon says Henle coincides in this view: "It cannot be doubted," says Schulz, " that the bloodcorpuscles are produced by the formation of a coloured capsule round the lymph-globules." These bloodSSee Reisseissen's admirable work entitled 'De Fabrica Pulmonum,' published at Berlin in 1832. 2 See Simon's 'Chemistry,' vol. 1st, 128--ilso Schulz, iiber die Gehemmte Aufl6sang, in ' Hufeland's Journal,' April, 1838. PNEUMONIA. 291 globules then are formed in the lungs, and a condition of their formation is, the integrity of the structure of the lungs and of the respiratory process. Once formed, they are carried in all the freshness of their youth to the left side of the heart, which propels them by its vis incita through the system, where as "floating centres of nutrition," to use the words of Dr. Martin Barry,' they subserve their great purpose in the animal economy, continually dying and being reproduced; so that our life is maintained at the expense of the lives of these myriads of monads which float in our arteries and veins. As the due formation, the birth, so to speak, of these globules implies the perfect integrity of the respiratory organs, so the proper relation of the capillary vessels of the body generally is required for the manifestation of those changes on which nutrition depends. Inflammation implies an enormous change in the relation of the capillary vessels to the contained blood. Inflammation consists of three stages; in the first the capillary vessels are contracted, and, according to hydraulic laws, the motion of the blood hastened-this is the latent stage, the existence of which was long denied, and still is by some physiologists, but which seems established beyond the possibility of doubt by the researches of W. Phillip, Kaltenbrunner, Wedemayer, Koch, and a host of others; in the second, there is a dilatation of the capillary vessels, the blood-globules are no longer transmitted. They adhere to the sides of the vessels, break up, their living tunic is destroyed, the red colouring matter diffused through the serum, and the central kernel escapes: it is 1 On the Nucleus of the Animal and Vegetable Cell, in 'Ed. New Phil. Journal,' for 1847. 292 PNEUMONIA. a question at present whether this central kernel is metamorphosed into a true pus-globule or not. The death and dissolution of the blood-globules implies the cessation of all the reciprocal actions which in health take place between the vessels and its contents, and with this arrest there stop also all those electric and other phenomena which Matteucci has shown to attend all vital processes. It may be, as suggested by Mr. Roberts,' that the inflammation is a de-electrifying process, and that a certain amount of electric action is necessary to neutralise the capillary attraction, and permit the free passage of the blood in health through the minute tubes. The blood also undergoes important changes. In all pure inflammations there is a considerable increase of the fibrine and a proportional diminution in the bloodglobules.2 At this stage the vessels are turgid, throbbing, the walls distended almost to bursting, the effect of this is an increase either of the general or special sensibility of the part; pain does not necessarily attend inflammation, but very often, we repeat, increased special sensibility, for each part has its own sensibility. This distension of the blood vessels and increase of sensibility disturbs the sympathetic relations of an inflamed part, and the heart which, though the most independent, is yet the most responsive organ of the body, participates in the local disturbance to a degree depending chiefly upon the amount of pain, and the extent of the lesion; besides, being thus forced to become a link in the chain 1 lMagazine and Journal of Science,' 3d series, July, 1841. 2 Andral, 'Essai d'H6matologie Pathologique,' 1843. A work we shall have occasion frequently to refer to-it is the standard one upon the subject. PNEUMONIA. 293 of morbid phenomena by sympathy, if the inflamed part be, as is the case with the lungs, a very vascular tissue, it may thus cause an undue opposition to the passage of the blood requiring increased mechanical force to overcome it. The third stage of inflammation consists in the restoration of the capillaries to their normal state, and as Talleyrand said that the worst revolution was a restoration, so in the capillary kingdom, the restoration of their original constitution is seldom effected without the formation of new products of every variety of kind. The most important for us at present is organizable lymph, which consists of a strong solution of fibrine apparently, and the tendency of this is to assume definite shapes, depending upon the form of the part where it is laid down. This is one of the most important terminations of inflammation.1 In applying these general facts to the peripneumonia of Hippocrates,2 the pneumonia of the moderns, we find that Stokes3 is one of the few writers who insists upon the probability of a stage in pneumonia prior to the first stage of Laennec. Whether this stage of the contraction of the capillaries be recognisable or not, may be a question; of its existence there can be none, unless we were to suppose a violation of all analogies in regard to inflammation of the lungs. In this stage of the pneumonic process there is a contraction of the capillaries of a Fletcher's 'Elements of Pathology,' art. "Inflammation." 2 Laennec observes in a foot note, that it is a common mistake to suppose the peri-pneumonia implied inflammation of the integuments as well as of the lungs. This it does not do in Hippocrates. 'Trait6 de l'Auscultation Mediate,' Paris, 1826, p. 393. 3 'Treatise on Diagnosis and Treatment of Diseases of the Chest,' part 1, p. 310. 294 PNEUMONIA. portion of the substance of the lung, that is of the minute air-vessels in which all the larger tubes terminate. As it is impossible to recognise with precision the moment of the accession of this change, so its exact duration cannot be determined. It may be coincident with the shivering which so frequently precedes an attack of pneumonia; but even if it were, this is too uncertain and irregular to be a good point de depart. The first stage of Laennec, and all practical physicians (except Stokes) is that of capillary dilatation and consequent engorgement. The lung in this stage presents just such appearances as might be expected, from the retention of a surplusage of blood in a very vascular spongy substance. It becomes firmer, of a livid or violet colour, and when cut into a coloured serous fluid as well as blood flows freely from the incisions. We learn nothing particular from the microscopic examination of this stage. The effects of the engorgement of the capillary vessels of the organ on whose integrity all the functions depend, must be numerous and important. The immediate physiological effect will be a sense of oppression, such as felt in the first stage of suffocation. The stimulus to inspiration is the presence of carbonic acid in the lungs, in undue amount; there is an instinctive sense of its inadequacy to support life, and an instinctive effort to get rid of the uneasiness its presence produces by breathing afresh, the less complete the success of each effort, the more frequently will it be repeated, even to panting. In the case of pneumonia this dyspnoea and accelerated respiration has a double origin, the first and far the most important is, the increased specific sensibility of the lung. The lung is specifically sensible to the PNEUMONIA. 295 presence of carbonic acid, but the inflamed lung is preternaturally sensitive. This position which we have nowhere seen stated, seems to us proved by the following considerations. First, the amount of abnormal excess of carbonic acid is very trifling; according to Davy,1 the difference of the quantity of air in the lungs before and after an expiration is as 118 to 108 inches, that is, about 10 to 13 inches are changed each time, or not much above a tenth. This is the amount of change in the whole lungs. Let us consider how insignificant the effect upon the general respiratory process, the occlusion of a lobule must have. Again: all causes which increase the pulmonary sensibility, augment the dyspnoea;2 as for example, an exanthematous disease. Besides, the lung may be occluded more completely, and to a much larger extent, as in phthisis, and even in what is called latent pneumonia, with little acceleration of the breathing, and without a trace of difficulty. Dyspncea then, which Grisolle speaks of as a constant symptom, and which for reasons obvious on a moment's reflection, is more important to us as homoeopathists than the physical signs of the disease, depends, like all other vital phenomena, upon the combination of two causes-the one a preternatural sensibility of the affected part to the natural stimulus on which its action depends; and the other an excessive amount of that natural stimulus. We have the phenomenon analysed in nervous asthma, and suffocation by carbonic acid gas. In the former the irritability is excessive, the stimulus natural; in the other the irritability is natural, the stimulus excessive-we are speaking at present only of the dyspnoea that attends the first I Simon's ' Chemistry,' p. 126. 2 Grisollc. 296 PNEUMONIA. stage, that which attends the third, or fatal stage, has different relations altogether. The explanation of most of the other phenomena are deducible from the accelerated respiration. The pulse is almost always full and rapid, more constantly so, according to Grisolle, than in ailost any other acute disease. Without entering more fully into the physiological considerations of the point, it is enough to observe, that the heart is so related both by the respiratory system of nerves, and mechanically to the lungs that it is almost inconceivable that it should not participate in any disturbance affecting them. The blood being the river of life which permeates the whole frame, it is manifest that whatever troubles it, must produce general derangement. Now the blood is very much affected in pneumonia. In healthy blood the proportion of fibrine is from two to three per mille.1 According to Andral,' in pneumonia it rises as high as ten per mille, higher indeed than in any disease, acute rheumatism excepted. With the increase of fibrine, there is a diminution of red globules, the normal average of these is, according to Lecanu, 127. About 114 seems the average in pneuinonia.3 It is obvious that so important a change in the blood and in the heart's action must affect both the cerebrospinal axis and the organs of digestion. Hence we find delirium frequent and intense, in proportion to the severity of the local disease; also foul tongue, constipation, highcoloured urine, and the other attendants of insufficient innervation of the alimentary canal and renal apparatus. Before leaving this part of the subject, we shall briefly Simon's 'Chemistry,' p. 245. Op. cit., p. 86. SAndral and Gavarret, Simon's ' Chemistry.' PNEUMONIA. 297 advert to the question of whether these important changes in the blood are primary or secondary. Dietl 1 argues that the changes in the blood are primary, and that on these changes the dyspnoea, delirium, &c. depend. The question has been set at rest by an experiment of Professor Henderson, who bled a patient at an early stage of pneumonia, and found that there was no increase in the quantity of fibrine.2 Besides, Andral lays it down as a maxim in hebmatology, that the exanthematous diseases never increase the proportion of fibrine nor diminish that of the blood-globules. Nay, that they seem to exert an opposing influence to this effect, when produced by an intercurrent acute inflammation; so that if a pneumonia be not very extensive, it will have no effect in deranging the proportion of fibrine blood-globules if it occurs in a person suffering under measles. Now, Grisolle mentions a case where there was slight pneumonia, but excessive dyspncea and other symptoms occurring in the course of an attack of measles, which proves that these symptoms could not be owing to the change in the blood as none would take place. We have one more observation to make on the cause of the dyspncea in pneumonia, it is extremely similar to that which precedes an attack of hmemorrhage from the lungs. Now, in all haemorrhages there is a diminution of the fibrine, not an excess; in fact, the state of the blood is diametrically opposite to that in pneumonia. The pathology of such haemorrhages is simple enough; there is a congestion of the lungs relieved by an effusion of blood. They often happen in patients whose nervous 1 'Der Aderlass in der Lungen entiindung,' Wien, 1849. 2 See 'Essay on Palhology,' in 7th vol. of ' Brit. Journ. of Homcopathy.' 298 PNEUMONIA. system is deranged, which may account for the excessive dyspnoea which precedes an attack of haemorrhagedyspnoea, greater than the limited portion of the occluded lung, accounts for on mechanical principles. The connection of haemorrhages with neuropathia is a subject of great interest to the physician, and one hitherto but little worked out. In this stage when the blood is accumulated in the vessels of the lungs, and the blood-globules broken down and dissolved, there is an exudation of bloody serum through the walls of vessels into the air-cells, whence result the rust-coloured sputa, so characteristic of the disease. It is probable that this takes place without any rupture of the coats of the vessels, for Reisseissen1 found that, when injecting a fine fluid into the pulmonary artery or vein, however gently he did it, yet some escaped into the air-cells. It may be some endosmosic process, or there may be slight rupture. It is impossible to decide, and it is no matter. The other symptoms of the pneumonia, the cough and pain, are no way peculiar, and are accounted for on the pathological principles which determine these phenomena generally. The cough is seldom troublesome, sometimes altogether absent; the pain quite uncertain in its seat, character, and degree. A fatal case of pneumonia of the right lung we once attended began by excessive pain in the region of the heart and dyspnoea. The cause of the pain in this case probably was owing to the anastomosis of the respiratory and sensitive systems of nerves. But a full explanation of this would occupy too much space. It is well, how ' Op. cit. PNEUMONIA. 299 ever to remember that latent pneumonia is often attended with severe pain in parts distant from the seat of the disease. The second stage of pneumonia consists of the secretion and deposition of certain matters from the bloodvessels into the air-cells and minute bronchial tubes. Meckel defines imflammation to be a congestion, with a tendency to a new production. The second stage may in some respects be considered as the termination of the diseased action, for if, as in haemorrhage from the lungs, the matter secreted were capable of immediate expulsion, then the congested vessels would at once return to their pristine integrity, and the functions of respiration go on unimpaired. But this is not the case; the matter secreted and effused must be looked upon as an altogether new formation which lies imbedded in the lungs, and undergoes certain transformations according to fixed laws of its being; and it becomes of the greatest interest to ascertain what this substance consists of, and what changes it tends to undergo. We may look upon this subject as exhausted, it has been so thoroughly examined; one of the best papers upon it is by Professor Henderson in the Monthly Journal of Medical Science, published in Edinburgh in 1841. There is also a very full and concise paper by Dr. Aitken, of Glasgow, in the Edinburgl Medical and Surgical Journal, No. 178. "Viewed under the microscope," says Professor Hasse, cc exudation of genuine pneumonia reveals a distinctly granulated condition, and, generally speaking, an 'Anatomical Description of the Diseases of the Organs of Circulation and Respiration,' by C. E. Hasse, M.D., &c., &c.; translated and edited by W. E. Swaine, M.D., p. 210-11. 300 PNEUMONIA. elementary composition varying as this second stage is more or less advanced. Numerous examinations have induced me to believe that in this kind of pneumonia the effused substances are originally fluid, then coagulate to a tolerable degree of solidity; and finally, again liquefy. In the primary form these substances, as above stated, display a number of blood-discs imbedded in a nearly amorphous, slightly granulated or striated mass. On being treated with water this mass still exhibits no cells (beyond a few shed ciliary cylinders), but numerous elementary granules either scattered singly or collected in groups. Acetic acid dissolves the greater portion of the mass, leaving unchanged only the elementary granules, and more or fewer spherical nuclei of various magnitudes. When some time elapses before the coagulation of the effused substances takes place, these nuclei become previously sheathed in spherical cells-exudation cells. After coagulation, the mass becomes amorpho-granular by mechanical division, a display of certain forms only, for the most part exudation-cells-is sometimes produced; by treatment with acetic acid this mass is again almost entirely dissolved, those elementary granules and spheroid nuclei alone remaining. With the ultimate liquefaction of the coagulate effusion the true development of cells appears to take place; and it now depends upon relations not clearly definable whether more exudation-cells or more pus-globules are developed. These two last forms constitute by far the greatest portions of the mass, and become readily discernible on the application of acetic acid. In this variety of pneumonia, granule-cells appear to form in very small numbers, and often not at all." Professor Hasse adds in a note-" These microscopic PNEUMONIA. 301 relations would hardly justify the adoption of the epithet -' Croupal,' as applied by Rokitansky to genuine pneumonia, inasmuch as the false membrane in real croup displays a different elementary composition." The most important considerations in a practical point of view in reference to this stage, are that the first and second stages are almost always going on together in the lung, though of course not in the same part of the lung, that we can hope to arrest the progress of the first but have no control over the second, and that the kind of deposition depends upon the state of the general health; thus in cachectic persons, the deposition is more granular, that is, more allied to pus, while in the vigorous it is more fibrinous, and sometimes, whatever Professor Hasse may say to the contrary, has all the properties of the false membrane of croup. Cases are recorded of pneumonia terminating in the coughing up of tubes having the form of the minute ramifications of the bronchia; so that it depends upon whether the patient is in a dyscrastic or euchrastic state, the peculiar organization or disorganization of the secreted deposit in his. lungs as the termination of their inflamed condition. We may observe, that with the setting in of this stage there is an immediate relief to all the sensible symptoms of the patient. In some cases this relief is almost instantaneous. The apparent relief afforded by bloodletting is owing to its frequently being made at the time when this second stage was just setting in. This fact is established beyond a doubt by Dielt.1 However, we do not mean to deny that bloodletting does SOp. cit. 302 PNEUMONIA. give temporary relief in this affection if performed at the time of the greatest engorgement of the lungs, and before much deposition has taken place. It acts by relieving the heart's action, lessening the amount of load propelled by that overburdened organ, also by reducing the quantity of blood in the gorged capillaries; but this it can only do by withdrawing blood from the general circulation, and thus augmenting the risk of inducing a feebleness of the system like that of dyscrasia, and so making it more liable to deposit rather the granular, inorganizable matter than the healthy and organizable in the tissue of the lungs, with, of course, the most disastrous ultimate issue to the patient. However, if we had not specific medicines to administer, notwithstanding all that Dietl says, we should bleed in the first stage of pneumonia in all healthy per. sons as a general rule. Let us, before passing to the third stage, recapitulate the characteristics of the second, technically called the stage of red hepatization. It consists of a deposit of an organizable, partially reticulated mass, and of granules in the air-cells, and ultimate air-tubes of the lungs. The organizable portion consists of a semifluid substance containing a quantity of half-dissolved, or suspended fibrine. The granules are peculiar bodies, from which pus is formed. The third stage of the disease, or that of grey hepatization, consists in the transformation of this effused jelly mass more or less entirely into pus by the agency of these pus-granules. The origin of pus-granules is not known. Some physiologists' suppose them to be Gendrin, Donne, &c. PNEUMONIA. 303 transformed blood-globule kernels; but this is extremely improbable. Professor Gluge,' in his short and admirable treatise on the blood, rejects this notion. He thus' describes the appearance of a pus-granule when magnified 300 or 400 times. "They consist of a whitish grey mass, somewhat elastic and of no great consistency; throughout the whole of this mass 4 or -5 dark points penetrate; these black points can be separated from the white pretty easily. The edges of the pus-granule are irregular, and slightly puckered (gefranzt); they preserve their original form for 14 days. By what process these bodies are formed is not known." Corruption and death are as great mysteries as organization and life:-" from hour to hour we ripe and ripe, and then from hour to hour we rot and rot." In a lung, which is the seat of red hepatization, the two processes are going on simultaneously, the formation of granules of pus, and the formation of organizable material. On the relative amount of the two actions depends the course and issue of the case. If all the effused material or the greater part were to be organized, we should have membranous tubes, as in croup, filling up the air-vessels and vesicles; and these might be permanent, and give rise to solidity of the lung which sometimes, though very rarely, remains after pneumonia. There is a preparation in the Hunterian Museum of Glasgow, of the lungs of a dog quite solidified by a cartilaginous deposit, which is only a different form of this organizable substance. If, on the other hand, the 1 ' Anatomisch - microscopische lUntersuchungen zur allgemeinen und speziellen Pathologie,' von G. Gluge. Minden und Leipzig, 1839. 2 Page 17. 301 PNEUMONIA. whole effused substance become purulent, then the lung is disorganized, for pus acts like a foreign body, and induces the destruction of the parts it touches, negatively if not positively. Between these two extremes we have every variety, depending upon the extent of the lesion, the constitution of the patient, and various other modifying conditions too minute and numerous to specify. We read constantly of the danger of tubercles supervening on pneumonia. Now, this termination is certainly not suggested by a study of the morbid anatomy of the diseases, and we find the highest authorities are against it. Louis,' the fountain of all our accurate knowledge regarding phthisis, very specifically rejects the notion after a most careful examination of eighty phthisical patients; and Grisolle,2 who is an equally high authority on pneumonia, sums up the question with the following statements:-" I conclude, from what precedes, 1st, that phthisis does not immediately follow pneumonia except in veryrare cases (less than one-thirtieth of the whole number); 2dly, that even under these circumstances it is by no means proved that the tubercular affection is a consequence of pneumonia-all presumptive evidence goes on the contrary to support the notion, that the tubercles existed before the pneumonia, and have, perhaps, acted as its cause. 3dly, that, in cases of exceeding rarity (since for my own part I have never observed such), where miliary tubercles appeared to form in hepatized lung, the pneumonia has then acted as the exciting, and by no means as the proximate cause. And I consider the diffusion of tubercles through the influ1 Louis, 'Researches on Phthisis,' 1846, p. 495, et seq. SOp. cit. PNEUMONIA. 305 ence of pneumonia in persons simply predisposed to the disease, as an occurrence- of great rarity. Thus, among 305 patients, whose cases I have analysed for this work, twenty-two presented those peculiarities of constitution which are commonly regarded as forming a predisposition to phthisis; besides, more than one half of them had had one or more of their nearest relations cut off by phthisis, and yet all these individuals, without exception, recovered from the attack of pulmonary inflammation, and left the hospital perfectly restored to health. Nor did the pneumonia in these cases differ either in respect of its cause, its symptoms, or its progress, from the ordinary pneumonia occurring in subjects not predisposed to the tuberculous affection.'' The mutual corroboration of two such men as Louis and Grisolle, we look upon -as finally settling the question, and we have no doubt it will relieve the anxiety of practitioners in treating this class of affection. Practically the most important thing to consider now, is whether there are any means of recognising and arresting, or modifying the transformation of the red into the gray hepatization, or the transition of the second into the third stage. After a most careful examination of the subject, Grisolle2 says-c"I conclude, from all that has gone before, that the two first stages of pneumonia may be certainly diagnosed (seront diognostiqu6s surement), and distinguished the one from the other, by the aid of auscultation, but that there exists at present.no stethoscopic symptom, nor any character of the expectoration, by which we can affirm that the pneumonia 1 Op. oit4 1 Op. cit., p. 499. 20 306 PNEUMONIA. has passed into the gray hepatization." That it is impossible to recognise the third stage we do not affirm, but when so experienced a physician as Grisolle tells us he cannot do it, we should certainly receive with considerable doubt the contrary assertion, however confidently made, of all ordinary practitioners, be they allopathic, hydropathic, kinesipathic, homceopathic, odylopathic, or any other pathic that is, or is to be. A disease we cannot know we cannot treat. And, therefore, we look upon the third stage of pneumonia, or that in which the deposited material is undergoing its process of corruption, as beyond the reach of direct remedial appliances, just as much as morbid action occurring in a foetus. Foetuses die of pneumonia; but how are we to find it out? and if we did, how are we to affect it? All we can do is to improve the mother's health. The individual is to the pneumonic mass, undergoing development, in the relation of a parent to a child-he gave it birth, and gives it nourishment, but it lives upon him for itself. Pneumonia terminates in recovery, more or less perfect, or death. The former is brought about by the absorption, in whole or part, of the deposited material into the mass of the circulation, where it is gradually eliminated by various processes, leaving the lung either perfectly sound or partially destroyed in structure, the cell-walls being broken down and the affected part lastingly weakened, and, in consequence, always more liable to a fresh attack; or not ruptured but solidified, by the formation of a thickened membrane upon the air-cells and tubes. Death by pneumonia is caused by suffocation. This PNEUMONIA. 307 does not imply a mechanical hindrance to the entrance of air into the lungs, it implies the arrest of the reciprocal action of the air upon the blood in the lungs. This impairment of the pulmonary function may arise from a structural change such as that caused by the pneumonic process, or by a change in the blood itself, or by a change in the innervation of the part. All these causes are combined in pneumonia: part of the lung is blocked up, in it the blood is not purified, because neither air nor blood pass through it. The rest of the lung is acting in most unfavorable circumstances. The blood is tainted, full of old globules not properly vivified, pus-globules, and the detritus of a corrupt lung. The lung, like every other organ and more than most, requires a full allowance of nervous influence (as is shown by the phenomena of asthma, which depends upon a partial paralysis of the pulmonary nerves), but the nervous centres cannot be up to the mark if not properly nourished, and impure blood does not nourish them. Last of all the heart, that " primum saliens et ultimum moriens," becomes involved in the fatal concatenation, it continues to propel the blood till the last, but such blood as the lungs furnish is of no use, and acts as a poison on the brain, so that in this, as in all other kinds of suffocation, a man dies poisoned by his own blood, to use the words of Bichat. As it is of great consequence to the practical physician to have a clear idea of the phenomena of asphyxia, we may sum them up in the words of the late Professor J. Reid, who investigated the subject in the most full and satisfactory way, and cleared up many embarrassing discrepancies, and rectified much pirevailing error: 308 PNEUMONIA. " We believe, then, that in asphyxia the order of succession in which the vital processes are arrested is as follows: the venous blood is first transmitted freely through the lungs, and reaches the left side of the heart, by which it is driven through all the textures of the body; as the blood becomes more venous, its circulation through the vessels of the brain deranges the sensitive functions, and rapidly suspends them, so that the individual becomes unconscious of all external impressions. The functions of the medulla oblongata are enfeebled about the same period that the sensitive functions are arrested (delirium is always a bad sign in pneumonia), but are not fairly suspended for some time longer. Immediately after. the sensitive functions are suspended, and the blood has become still more venous, it is transmitted with difficulty through the capillaries of the lungs, and, consequently, begins to collect in the right side of the heart. A smaller quantity of blood must now necessarily reach the left side of the heart, and this diminution of the quantity of blood sent along the arteries, conjoined with its venous character, and the ultimate arrestment of the circulation, being circumstances incompatible with the manifestation of vitality in the other tissues of the body, general death is sooner or later induced."' The indications for the treatment of pneumonia are extremely simple. We must find a medicine which has the power of arresting the first stage, that is of restoring the capillaries engorged with blood, and preparing to deposit the substances we have described as peculiar to this disease, to their natural state, and, at the same time, 'Edinburgh Medical aud Surgical Journal,' vol. lv, p. 450, for the year 1841. PNEUMONIA. 309 we should allay the sympathetic irritation of the system, on which the general fever depends. If we can arrest the progress of the engorgement, we quench the circumference of the conflagration, and we may leave the morbific matter which has been deposited to be disposed of according to the laws of morbid action. If we can find any medicines which act directly on the tissue of the lung, and produce this inflammatory action, then we may be satisfied that they will operate curatively in pneumonia. In considering the relative value of the different medicines we are about to cite, we must place much more reliance upon clinical experience in ascertaining their worth in this disease than in most others, for pneumonia offers so few unequivocal rational signs that we cannot certainly predicate of the effects of a medicine, as exhibited in its proving, that they are those of pneumonia. However, we need regret this the less as we have ample and undoubted clinical experience to assist us, and we may say that our knowledge of the treatment is now as perfect as our diagnosis of the disease. In the observations we are about to make, we have been much indebted to a series of articles that appeared in the first three numbers of the ' Homiopathische Vierteljahrschrift,' by its painstaking editor, Dr. C. Miiller, and we have no hesitation in using the materials he has presented, without ourselves verifying their accuracy by comparing them with the original sources whence he obtained them. The only medicines which we propose to consider are Aconite, Bryonia, Phosphorus, and Tartar emetic. For, on a careful perusal of the proving of the other medicines cited in Dr. Miiller's paper, and the alleged cures of pneumonia by their administration, we come to the con 310 PNEUMONIA. clusion that the evidence for their being of such decided use as to warrant their employment in pure pneumonia was quite insufficient. Even Belladonna we do not admit, although we have high testimony in its favour. This testimony, however, is qualified by the observation of its great utility in pneumonia occurring with scarlet fever, which entirely alters the case, and, as in this paper we have refrained from noticing any other form of disease than pure pneumonia, we do not deem it expedient to enter into an investigation of the virtues of Belladonna in this complication. There would be abundance of material for another paper upon the complications of pneumonia and their treatment, and we trust some experienced physician may take up this subject. Our chief reason for rejecting the evidence in favour of the utility of Belladonna, Pulsatilla, Zinc, &c., is the extremely bald narration of the cases in which they were said to be of use, and really we are ashamed to record that out of a very large series of cases collected by Dr. Muller from the various journals, there is hardly one in which the diagnostic signs of pneumonia are given in a way to satisfy a modern physician. To this general remark there are some honorable exceptions. Without further preface, we shall consider the claims of Aconite as a remedy in the first stage of pneumonia. The proving of Aconite in the Oesterreichische Zeischrift fiir Homdopathie, by Dr. Gerstel, of Vienna, is so perfect that it leaves us nothing more to wish. Experiments on animals prove that Aconite induces engorgement of capillary vessels generally. It was found by Dr. Prevost,' that if Aconite much diluted by water S' M6moires de la Soc. de Phys. et d'Hist. Nat. de Geneve,' t. vi, p. 1. 312 PNEUMONIA. proving for themselves, and we think that they will be convinced that Aconite does tend to produce congestion of the lungs, as well as general inflammatory fever, and that, therefore, it is a priori well suited to the treatment of the first stage of pneumonia. The two following cases, although in neither have the physical signs been observed, still seem to possess undoubted claims to our acceptance, as cures of pneumonia by Aconite. A mason, seventeenyears of age, of strong constitution, presented the following symptoms: throbbing headache, chiefly frontal; eyes bright, with contracted pupils, and over sensitive to light; face dark red, hot, and puffed; dry lips, white coated tongue; bitter taste; much thirst; constipation; scanty bright red urine; respiration short, superficial, laborious; oppressive and painful pressure on the chest, especially under the sternum; cough frequent and short, with heavy blood-streaked expectoration; stitches in the right side on inspiration, increased on coughing, deep-breathing and every movement; inability of lying on the side; continuous burning dry heat, with cold feet, preceded by rigors; pulse quick, full, hard; weariness and sense as if the body had been beaten; sleeplessness, anxiety, and restlessness. A drop of the 12th dilution of Aconite every four hours for six times. After the third dose, general perspiration set in, and after waking, there was decided improvement in his condition. On the next morning the headache, thirst, oppression of breathing, and pressure at the heart, beaten feeling, anxiety, and restlessness were all gone. There was an alvine evacuation, the urine deposited a sediment, PNEUMONIA. 813 there was a general transpiration from the surface, the pulse was slower and softer, the breathing calmer and freer, the cough less frequent, with a little pure slimy expectoration; he could lie upon the side, and the stitches were only felt on taking a full breath or coughing; appetite also returned. The following night he slept well, only coughed a couple of times, and went to his work the succeeding day. This case is recorded by Dr. Gulyas, in vol. xix of the Horn. Arciv., and we concur with Dr. Muller in his remark that this rapidly-cured and well-described case makes us the more regret the absence of the physical indications of pneumonia. The next case is by Dr. Trinks, of Dresden, whose name is in itself a guarantee for the correctness of the diagnosis. A robust maid-servant, thirty years old, after being exposed to cold and wet, was attacked with severe rigors and stitches in the breast. The next morning the following symptoms manifested themselves: dull stitching, pressing pain in both lungs, which obliged her to lie upon her back and prevented deep breathing; frequent short cough, with incessant inclination to it; great dyspnoea and anxiety, which would not let her lie still, and expressed itself in the countenance; face dark blue, puffed; pulsation in the carotids; dryness in the mouth and thirst; bloody taste in the mouth; general dry heat; pulse slow (?), oppressed, small; drawing pain in the limbs. After a dose of the 24th dilution of Aconite, transpiration set in upon the first night; the breathing 314 PNEUMONIA. was freer; expectoration slimy and without blood; the pains in the limbs were gone. The cure was completed by Bryonia.' We are disposed to regard this as a case of incipient pneumonia, in the first stage of Dr. Stokes. If pneumonia at all, it was a wonderful cure, but far from incredible. Dr. Wurmb,2 an excellent practitioner, expresses himself as convinced of the utility of Aconite in pneumonia, and that it does not merely allay the fever but has a specific action upon the lungs. Dr. Buchner,. also expresses himself satisfied of its usefulness. We should gladly avail ourselves of Dr. Miiller's sensible concluding paragraph, had we space. We can only recommend his whole article to the attention of our readers. If we admit, as we must, that Aconite is the proper medicine at the beginning of a simple pneumonia, the next thing to determine is the dose. We find all doses, from the 1st to the 24th dilution, of use; and for our own part we usually employ the third, but can lay down no rule. We have ample facts to show the efficiency of all dilutions, and none to show the superiority of any. BRYoNIA.-Although its effects upon the digestive system, and upon the serous membranes and muscular tissue are much more prominent in the admirable proving published in the 3d vol. of the Austrian Journal, yet we find unequivocal symptoms of its direct effect upon the 1 'Annal. der Horn.,' K. 1, 24. ' Hygea,' ix, 1, s. 53. Ibid., xv, 6, s. 503. PNEUMONIA. 315 parenchyma of the lungs; and we must remember that, owing to the slight general sensibility of these organs, and the great sensibility of those others affected by Bryonia, that it will require fine discrimination to pick out the pathogenetic signs of an effect upon the pulmonary tissue. The dumb sufferings of the lungs are not easily recognised amid the clamour of the stomach, bowels, and muscles. The appearance of the lungs in a rabbit poisoned by it gave unequivocal evidence, however, of its direct action on these organs. This experiment was made by Loewy, of Vienna. After the animal had taken three successive large doses of Bryonia, it died; and on dissection, the lower half of both the lungs were found of a dark flesh-red colour; they did not crepitate, and sank in water.' Among the provers, the most marked symptoms were the following: Surgeon Huber, after taking Bryonia in large quantities for several days, describes that one day, about one o'clock, his respirations became greater while driving, and he experienced the feeling as if the upper part of the chest were too tight. (This is exactly the sensation given by a congestion of the lung, as we have frequently had opportunity of observing). The tightness of the chest, and a raw feeling under the sternum, increased to such a degree as to oblige him to alight from the carriage. Dr. Wiirstel, after the continued use of the medicine for some days, states, that one day, after he had taken twenty-five drops in the morning, he was affected in the forenoon with stifled breathing (beklommenes athmen), and a weight in the middle of the 1 (Ester. Zeitsch. fiir Horn.,' vol. iii, p. 96. 316 PNEUMONIA. breast." This is either from congestion of the lungs, or from some effect on the nervous centres which Bryonia does not produce. "The saliva is twice mixed with clear blood." Taken in connection with the oppression of the chest, it is probable that the blood came from the lungs; at all events, it produced a hIemorrhage of some part of the mucous tissue which lines the respiratory organs; and as we pointed out before, the first stage of pneumonia is extremely analogous to the congestion which ends in hmmorrhage. This evidence for the direct effect of Bryonia on the lungs, though scanty, is goodand we have such ample clinical experience of the utility of the drug, when administered in the disease, as to supersede the necessity of any more a priori evidence in its favour. By far the most important book upon the treatment of any disease which has yet appeared in homoeopathic, we may say in medical literature, is one by Dr. Tessier on the treatment of Pneumonia and Cholera. It is intitled' Recherches cliniques sur le traitement de la pneumonie et du cholera suivant la methode de Hahnemann.' Precedes d'une introduction sur l'abus de la statisque en medecine, par le Docteur J. P. Tessier, Medecin de l'H6pital Sainte Marguerite (H6tel Dieu Annexe), a Paris.-Bailliere. Our readers are no doubt already somewhat acquainted with this book through the able papers of Dr. Ozanne, which appeared in the.Homropat/dc Times. What gives this book such immense importance in our eyes is, that it is the first time the system of homceopathy has been fairly carried out in a public hospital by a physician of the old school who had ample opportunities of comparing his former and later PNEUMONIA. 317 success, and who has given us such unexceptionable reports of every case he treated. It is utterly impossible for any one who is capable of appreciating evidence, to gainsay the potency of this. The cases are admirably described,-how different would homoeopathy be had all the homoeopathic cases been so narrated! The total number of cases treated was 41; of these, 38 recovered and 3 died. He comes to the following conclusions: "1. In all, the disease was making progress up to the moment of treatment. "2. As soon as that had commenced, an aggravation ensued, which lasted in general less than twenty-four hours, and the remission began either partially or over the whole extent. From this time everything converged rapidly towards cure. Sometimes the amelioration began without previous aggravation, and went on without a check to perfect cure. "3. The pulse showed an extraordinary influence of the Bryonia. - It was noticed to fall 20, 30 pulsations on the day of its administration; on the succeeding, 65 after it had arisen to 110 or 120; it went down to the time of the resolution of the pneumonia, to 60, 50, 44. I saw it fall to 36 in an individual, the history of whose case is not given. I have seen it fall from 120 to 80 in the interval of the morning and evening visit, to go down to 60 the following morning. "4. In the case of old people who had passed whole weeks previous to treatment, and in whose case the termination by induration appeared to be inevitable, this 318 PNEUMONIA. result did not occur in one single case; all that was observed was, that the disappearance of the physical signs was somewhat protracted. "5. Lastly, suppuration did not take place in one in whom it had not begun before the commencement of treatment. In the case of several it appeared to be limited; in one case alone it was neither prevented nor arrested, (in my view the two brought in in agony of death are not to be taken into account (a mes yeux les deux agonisants sont hors de cause.)" We have made out a table showing the number of days each was under treatment, and how long the patient had been ill before he was treated. PNEUMONIA. -319 Cases. Entered. Undreernt.

October 10th 1 In almost all Tessier's cases, Bryonia at the 24th dilution was the sole, or nearly the sole medicine; in some, Aconite was given before Bryonia. That they establish beyond the possibility of a doubt the great efficacy of 320 PNEUMONIA. Bryonia in this disease is certain; it may still, however, be a question, whether the frequency of the aggravation he noticed would not have been avoided by some doses of Aconite. It is a common practice to give Aconite and Bryonia in alternation, and although it is a mode of procedure at variance to the strict injunctions of Hahnemann, it certainly has much to recommend it. It is our usual method in cases of pneumonia and pleurisy to give these two medicines alternately, and we are disposed to think that the results were more favorable than if either had been given alone. We have no space to enter into an apology of this, but we think we could show, from physiological principles, that it is not so inexcusable in practice as it at first appears. And, certainly, the two medicines do not counteract each other. We have the same remark to make upon the dose of Bryonia as upon that of Aconite. We do not know any facts proving the superiority of any dilution. Tessier used the 24th; we generally use the 3rd or the 6th. Perhaps both are right. The adaptation of PHOSPHORUS to pneumonia can be established both by the proving of the medicine, and its extensive and most successful application. The fumes of Phosphorus produce an affection of the mucous membrane of the bronchial tubes, since cases of this kind, which occurred in La Pitie, are related by Gendrin; and in the following case the inflammation seems to have affected the smaller bronchia, and nearly approached pneumonia. The case is related by Bibra and Geist:1 'Die Krankheiten der Arbeiter in den Phosphorziindholzfabriken,' von Dr. V. Bibra und Dr. Lor. Geist, Erlangen, p. 11, 1847. PNEUMONIA. 321 "John Zitman, 52 years of age, large, lean, but well built, broad chested, strong constitution, without any disposition to phthisis; was for three-quarters of a year in a lucifer-match manufactory, and chiefly employed with dipping the matches (Tunken der Halzchen); soon after beginning the work he was attacked with a dry cough, which disappeared under a warm regimen and diaphoretic drinks. In the course of half a year he became ill of the same affection, which, however, was now more severe, and obliged him to quit his work. On examining him, the face was red and congested, the brow covered with sweat, the tongue coated, the taste nauseous; there was frequent desire to cough, with flying stitches under the sternum, and the right side of the thorax, with a continual tickling and scratching feeling at the bifurcation of the bronchi, anxious, short and quickened breathing, with heaving of the whole thorax, but more especially of the left side. The percussion elicited a clear sound in the middle of the right side; auscultation showed extensive mucous rale with pectoriloquy. The pulse was quick, small, hard, the skin dry and hot, much thirst, great weakness and prostration." Although the narrator calls this a case of bronchitis, it seems to us manifestly one of hepatization of the lungs, for without this or previous chronic disease we are not aware of pectoriloquy ever taking place. The physical signs are somewhat anomalous no doubt. We do not think it necessary to quote from Hahnemann's Materia Medica the symptoms which correspond to pneumonia, as the book is in the hands of all our 21 322 PNEUMONIA. readers. The short frequent cough, with sense of oppression at the chest, and expectoration of mucus streaked with blood, in combination with fever-symptoms point unequivocally to the direct action of this substance upon the lungs. It is by the steady persevering use of this remedy, and of this one alone, that Dr. Fleishmann has acquired such celebrity in the treatment of pneumonia. Up to the year 1844 lhe, and his pupil Dr. Reiss, of Linz, had treated in all 379 cases, and had lost only 19, or 1 in 20; the last 44 of Fleischmann, and 34 of Reiss having all recovered. Dr. Fleischmann is frequently blamed for what is called routine practice, but we must recollect that pneumonia is a routine disease, running a definite course, depending, as we have shown, upon certain simple and constant structural changes, and we see no reason why there may not be a specific for all cases of simple pneumonia occurring in healthy persons. And, for our part, we greatly prefer an undeviating adherence to a remedy which on the whole suits the disease, than a striving after something which seems to correspond to every little symptom of the individual case. We have seen some very remarkable examples of the efficacy of Phosphorus in this disease; for the particulars of the following case we are indebted to Dr. Black, in the accuracy of whose memory we have the greatest confidence: " I perfectly recollect," he says, " the general features of a case of pleuro-pneumonia, treated in the Edinburgh Dispensary, in the spring of 1842, though I do not remember the details. The patient was a middle aged apparently healthy man, and on examination there were . PNEUMONIA. 323 all the physical signs of pneumonia of one side, with great fever. We gave him Aconite, and sent him home in a cab. Next day the fever still ran high, and there was no improvement. As we had brought the Tincture of Phosphorus with us, by mistake for the first dilution, we gave him a drop or two of that in a cup of water, of which he was to take some every one or two hours. During that night the dyspncea had so increased after every dose of the medicine, and he became so alarmingly ill, that extreme unction was administered. At our visit next afternoon we were surprised to find the patient so much better, the pulse nearly natural, no dyspncea, respiration natural, but still little or no diminution in the physical signs. He made a rapid recovery. What impresses the case on my memory was the aggravation of the strong dose of Phosphorus, the speedy relief afterwards, and rapid disappearance of all rational signs without any diminution of the physical." We beg our readers to pay particular attention to this most important case, it is full of instruction. We shall conclude our notice of Phosphorus by quoting Dr. Fleischmann's words: "I used formerly to employ the ordinary remedies, Aconite, Bryonia, Cannabis, &c., in pneumonia, and that with considerable success, but each of those remedies is adapted only to particular cases, or rather to particular phases of the disease. Thus it happened that besides the difficulty I experienced in discovering the medicine adapted to the particular case-which is no easy matter -I was frequently left in a state of disagreeable uncer 324 PNEUMONIA. tainty as to the remedy which had effected the cure. Now, however, I have attained much greater certainty, since for the last year and a half I have administered no other substance than Phosphorus in every case of pneumonia, under what form soever it might present itself; and I think I may, with perfect confidence, pronounce it to be a true specific. * * * * "I have seen the most violent cases of pneumonia in every variety of constitution and season, come to a happy issue by the sole employment of this remedy; cases in which ahnost two thirds of one lung were hepatized. * * * I administered the Phosphorus dissolved, as Hahnemann recommends, in AEther, ( * "*) only quantitively stronger-10 grs. or drops to 100 of sugar of milk or alcohol. The formula I employ is: a. Phosp. 3-6 gtts. iv-viii. Aquae disti. 3ii-iv. A spoonful to be taken three to six times daily.!" TARTRATE OF ANTIMONY was introduced into therapeutics as a cure for pneumonia by Rasori, who gave it in very large doses, and since his time it has been generally used by the old school. Of its specific action upon the lungs there can be no doubt. Magendie, in a memoir, entitled, "L'Influence de l'Emetique sur l'Homme, 1833," describes its effects thus: " The lungs present the appearance of the greatest alteration: they are of an orange colour if the animal is young, violet if it is older; the tissue is kepatized, gorged with blood at some parts, and at others very analogous to the tissue of the spleen." In whatever way introduced "it acts 1 Brit. Journal of -Iomceopathy,' vol. ii, p. 45. PNEUMONIA. 325 specifcally in inflaming the lungs and the mucous membrane which lines the intestines from the cardia to the anus." Lepelletier, who has written an excellent monograph upon this drug,' observes, " Its effects on the respiratory organs is to produce dyspnoea in dogs which were in perfect health before its administration, the lungs were found hepatized, lost their colour, and scarcely crepitated at all. One would imagine that admitting its action in man to be similar, far from being useful, its administration would be particularly pernicious in the treatment of pneumonia; but it is not so, for we shall see that far from favouring engorgement of the lung, it induces its resolution." Out of 652 cases of pneumonia treated by Rasori, in the Civil Hospital, 505 recovered, 147 died, giving a mortality of 22 per cent. Of the whole number 1 in 16 were bled. In the Military Hospital, 180 were treated, 154 recovered, 16 died, giving a mortality of 14 per cent. The proportion bled was 1 in 16. Ambroise Laennec treated 40 cases after Rasori's plan, in the H6tel Dieu de Nantes; of these 1 died out of every 13, giving a mortality of 8 per cent. We may. here introduce a curious table by Dietl,2 giving the comparative results of bloodletting, tartrate of antimony, and nothing. 'De l'emploi due Tartre Stibi6; a haute dose, par Alm.

In the mean time we may conclude by observing of these remedies, as Go~the did of himself, that Germany, instead of contending whether he or Schiller were the greater, should be very thankful that she had two such men to contend about: so we may be very thankful we have four such remedies to choose among in pneumonia, as Aconite., Bryonia, Phosphorus, and Tfartrate of Antimony. CHAPTER VIII. THE SKIN AND ITS DISEASES. THE morbid appearance of the external surface of the body may be regarded from two essentially distinct points of view; either as constant and characteristic manifestations of some general derangement of the whole system, or as independent affections of the skin itself. This broad and obvious distinction seems to have been constantly present in the mind of Hippocrates whenever he mentioned this class of diseases. For example, in speaking of some eruptions which happen in childhood, he says "Lichen, leprosy, and leuce, when they occur in* young children and infants, or when they appear at first small, and gradually increase in the course of a long time,-in these cases the eruption is not to be regarded as a deposit but as a disease; but when they set in rank and suddenly, this case is a deposit."' It seems scarcely credible that a distinction so fundamental and practical should have been allowed to slip from the minds of later writers on dermatology. The explanation of the retrograde movement is apparent if we read almost any recent work on this subject. Take, for instance, the essay by Dr. Paget, which obtained Alibert's prize in 1832.2 Here we find the prevailing 1 'The genuine works of Hippocrates,' Sydenham Society Edition, vol. i, p. 269. 2 An Essay on the comparative merits of artificial and natural classi 330 THE SKIN idea of classification derived from the systems of botany and natural history, and the different methods of arranging diseases are tried by the canons of Decandolle. It seems almost a waste of words to show that this hopeless departure from the rules of common sense can only deepen the confusion of a subject in its nature sufficiently perplexed and difficult. All classification of objects of natural history is essentially an arbitrary catalogue, arranged for some specific purpose. No sane man can suppose for a moment that the botanical characters of a plant, however complete, express the whole properties or qualities of the individual so designated. If a cook were given the most perfect botanical work in the world, and told to make a dinner out of it for a party of vegetarians, arranging her materials as she found them arranged by Jussieu or Decandolle, she would get no botanist at least to partake of her repast, for he would know that plants which stood side by side in conjugal amity in his table, if transformed to the dinner-table after being subjected to the matrimony of the stewpan, would effectually pre* vent him from ever making any experiments beyond the province of toxicology. The botanist has no more to do with the poisonous or gustatory properties of plants than the astronomer has with the astral influences on the lives of men; and it would be as reasonable for a believer in astrology to apply to I-Ierschel for his horoscope as it would be for a gastronomist to go to Linnaeus for a dinner. Science does not pretend to deal with those finer qualities of its subjects on which their practical fication as applied to Diseases of the Skin, by John Paget, M.D., 'Edin. Med. and Surgical Journal,' No. 115. AND ITS DISEASES. 331 utility depends. But it subserves a most important end in giving a perfect catalogue and a general nomenclature to the seemingly innumerable objects around us. For a power to fix a name upon a thing, or an animal, first used by Divine authority in Eden and never become obsolete, will always continue to play an important part in the subjugation of the material universe by man who got along with this government the power of speech. Even in the so-called natural systems, objects are not arranged according to their nature, only according to their agreement in possessing a certain number of constant characters; for science having its origin, end, and limitations in the mind of man, can never attain the entire knowledge of nature which stretches into infinitude around us: and there may be a multitude of arrangements all -perfect of their kind. The naturalist, the painter, the poet, and the practical man, may each make a classification sufficient for his purpose; but neither singly nor united do they exhaust all the relations or qualities of their subjects. Medicine being essentially practical or nothing, no good, but, on the contrary, much evils results from transferring systems which do not yield practical service in the treatment of disease into this department of art. That to do so is both futile and mischievous may be seen by the entire failure of the attempt even in the most learned and skilful hands. The essential idea of classification, as we have already said, is, that certain constant characters of an object are taken according to which it is designated, and from which it may always be recognised. Let us apply this simple criterion to a so-called disease of the skin. We shall take scarlatina. "The scarlet fever," says Bate 332 THE SKIN man,' "is characterised by a close and diffuse efflorescence of a high scarlet colour, which appears on the surface of the body, or within the mouth and fauces, usually on the second day of the fever, and terminates about five days." According to Mr. Erasmus Wilson,2 by far the best modern English writer on the subject, " Scarlatina is an acute inflammation of the integumentary investment of the entire body, both cutaneous and mucous, associated with fever of an infectious and contagious kind." Inflammation is defined as being redness, heat, pain, and swelling: so that scarlet fever is characterised scientifically by the presence of redness, heat, pain, and swelling of the skin at least; at all events, we may expect always to find redness and heat of skin in this object (for at present we must regard it as an object of natural history). A few pages further on we find that cases occur without any or scarcely perceptible efflorescence, i.e., inflammation of the skin. So the character on which the classification of this object is founded vanishes!-as if we were to define man as an animal with a head, a trunk, and four extremities, and to add that occasionally men are met with who have none of these peculiar signs of humanity! Hence we maintain that the attempt to introduce into medicine the kind of definitions which are suitable for the purposes of natural history, and to found a classification of diseases upon them, is manifestly futile. The mischief done by the attempt, although not quite so apparent, is not less real; for, as the only object in grouping diseases together is to improve our treatment of them, it follows S'A Practical Synopsis of Cutaneous Diseases,' 4th edit., p. 69. 2 'On Diseases of the Skin,' Erasmus Wilson, 3d edit, p. 62. AND ITS DISEASES. 333 that there should be some similarity in the management of members of a family that are linked together by fraternal propinquity. Let us apply this test to the four junior members of the ancient family of exanthemata Urticaria, Roseola, Purpura, and Erythema. Except Morison's Pills, we cannot conceive of any medicine which could by any possibility be employed against one without being almost certainly injurious to the others of this group. So that if we were guided in our treatment by this classification, we should undoubtedly be doing harm; and this we take it is a sufficient condemnation of the system. The most remarkable example of extravagance in classification ever perpetrated in medicine is afforded by Alibert's famous tree, and which should be a warning against any such attempts in future. Still, order is of such paramount importance to the successful conduct of all human affairs, that the effort to obtain a profitable arrangement of the numerous and complicated maladies which affect the skin ought never to be abandoned by the physician; and of late juster principles have begun to be acknowledged, which promise to introduce a new era into this department of study. Recurring to the felicitous expression of Hippocrates, every morbid appearance on the skin is either a deposit or a disease-a deposit if it be merely a symptom of an internal disturbance in the system, a disease if it be a local affection of the cutaneous organs. If the prevailing idea that the true typhus of this country is always attended by a specific eruption be adopted, it would be as rational to call it a disease of the skin as to give that appellation to measles or scarlet-fever or small 334 THE SKIN pox; and had Willan been now alive and in the ascendant, we might have had typhus ranged beside urticaria and pupupura. In that class of diseases of which we may take measles as the type, there is a tendency to deposit themselves upon the surface, and when this effort is checked they fall upon some other part of the frame, producing often strange and unmanageable disorders. For example, there is an instance narrated in the Archlives Generales, in which the sudden disappearance of the eruption of measles was followed by total loss of the power of speech, the patient remaining dumb for two years; and the converse of this has been also known to occur, and speech long absent to have returned with the reappearance of measles. Hence we see that although the eruption upon the skin in those diseases does not constitute the true morbid affection, yet there only it seems to find its natural seat of expression; and the changes which the skin undergoes are a legitimate subject of investigation. For the development of a pimple or a vesicle and pustule may be exactly the same whether the exciting cause be from within or from without. The pustule produced by Tartar emetic seems quite identical with that of smallpox, and as a pustule may be studied; so that in a scientific examination of diseases of the skin, all changes of structure in that organ come under consideration, although the part which the eruption plays in the total disease may be quite subordinate and even accidental. As, for example, in purpura, which is sometimes confined to the lining membrane of the intestines.' As the internal disturbSee a case which occurred in the Edinburgh Infirmary, referred to in 'Edinburgh Medical Journal,' No. 115. AND ITS DISEASES. 335 ances of the body affect its external covering, so skindiseases of a purely local character may, by the irritation they produce, react upon the general health of the rest of the system; and, besides, there are affections which have sometimes a local and sometimes a constitutional origin, as, for example, erythema, which is produced either by some stimulant applied directly to the skin, or occurs as a symptom in the course of a chronic disorder of the whole body. The confidence we now feel of a great improvement in our knowledge and consequent arrangement of diseases of the skin, is derived from the immense progress recently made in the anatomy, physiology, and pathology of that organ. It is certainly the most complicated structure in the human frame; and until the various constituent parts were separated, and the laws of their healthy and morbid development ascertained, it was a hopeless task to introduce order into their arrangement. And the advance in pathology will necessarily be followed by a corresponding improvement in the treatment both general and specific, -that is both hygienic and homceopathic; for as all just views of hygiene are derived from physiology, so a more accurate pathology leads to a nicer adaptation of the similar remedy. Indeed a true pathological classification or arrangement is identical with a homceopathic one; for as homoeopathic practice consists in adapting to a diseased action the remedy which excites the nearest possible similar diseased state, it follows that a closely allied morbid condition occurring riaturally in the system will also be probably benefited by this remedy, which bears to it too an approximate similitude,-for things equal or like the same thing must be equal or like one another. 336 THE SKIN It is for this reason that we propose to enter very fully into the detail of the structure and pathology of the skin, before making any mention of the treatment proper for its various diseases; and we do so with less reluctance, because many of the most important discoveries in dermatology are of so recent a date as not yet to have been absorbed into the general medical mind. The cutaneous covering of the human body consists of epidermis, cuticleor scurf-skin, c; pigmentum nigrum; culis, corium, or true skin, called in German Leder-haut, d, or leather-skin, containing }-"^ -T - muscular fibre and two ^ y ^setsof secreting glandsSthe sebiparous, h, yielding I: theunctuousmatterwhich i.......... lubricates thesurface, and j:h Hthe sudoriparous, b, which S..secrete the perspiration; also hair and nails.

The mosaic appearance it presents is due to its cellular construction. The cells of which it consists are formed of granules similar to those of the blood-globules whence they are derived. On the surface of the membrane which separates the cutis from the cuticle such a granule is deposited. This may be called the embryonic spot of the epidermis. It contains the element of its own independent development, and lives upon the skin, from which it derives the materials of its increase. The first step it takes is to associate to itself other minute granules, out of which combination is formed an aggregated granule, which is one ten-thousandth of an inch in diameter. Around this little mass as a centre other granules range themselves in a circular form, in the centre of which lie the original granules, somewhat changed in appearance by the pressure to which they have been exposed, which being generally unequal gives them an elongated form, and the space between these bodies is filled with a transparent and homogeneous matter. Besides the changes which the central or parent nucleus of the cell undergoes, the granules which constitute its circumference become themselves centres of aggregation of other granules, so that there is a continual process of encroachment going on upon these respective territories of the two, which, combined with constant formation of new layers of a similar nature taking place upon the membrane which gives them nourishment, accounts for the appearance of scales they assume as they become external previous to their final exfoliation from the surface. The scales are nothing but a congeries of compressed cells, as the cells are nothing but associated granules. 22 338 THE SKIN There is no vascular connection between the epidermis and the skin, the one merely lives upon the other as lichen on the bark of a tree, imbibing nourishment from it by the process of endosmose, and turning the food so obtained to its own use. It has no power of regeneration or healing such as the rest of the body enjoys, and if a division be made in its continuity the separated edges do not reunite. It is of various degrees of thickness in different parts of the body, and this variation does not depend upon external causes but upon its own nature, for the varieties are found in the foetus as well marked as in the adult. The cuticle on the palms of the hands and soles of the feet of the unborn infant being many times thicker than that which covers the rest of the body. At an early period of foetal life the epidermis round the mouth does not consist of scales, but of polygonal cells filled with fluid, such as are met with in plants.1 Among the other alterations which the epidermis undergoes as it is pushed outwards by the incessant growth from below is one of a chemical nature. The young cuticle is soluble in vinegar, but the old scales are transformed into horny matter which resists this solvent. The pigqmentum nizgrum seems to consist simply of coloured granules, similar in all respects to those just described, with a slight admixture of some colouring matter of greater or less amount according to cir'cumstances. In the negro all the central granules are dark, in the European a certain number of dark ones are mixed with the lot. We may close this description by a few words, ex ' Ruschkow 'Melemeta,' p. 12. AND ITS DISEASI S. 339 plaining the so-called Rete Malpighi. This appearance, which was supposed to be owing to an intermediate reticulated membrane between the epidermis and true skin, is satisfactorily accounted for by the lower layers of the cuticle having been moulded round the prominences of the papillae of the culis, and thus when removed presenting the aspect of holes in a flat surface, the holes corresponding to the places through which the eminences of the true skin protruded. Hence the cribriform appearance mistaken by Malpighi for a net, and called rete mnucosum; for, as we have said, the lower strata of the epidermis are of softer structure, more mucous-like, than the more external layers.1 The nails may be included in the epidermic tissue. They are in fact little else than thickened indurated cuticle, consisting of two layers, both laminated, the external one harder and thicker than the one beneath it, which rests upon the true skin. They grow upon a furrowed bed, and increase both at the end, by which they are attached to the finger or the toe, and along the whole course of their connection till their free end. The bed on which they are moulded is composed of bundles of papilla arranged side by side lengthways, those nearer the finger-end are fuller and richer than those at the root of the nail. Hence that obvious difference of colour in 1 This description is derived chiefly from the works of Erasmus Wilson, Henle, 'Allgemeine Anatomie,' 1841, and an admirable treatise on ' Skin Diseases,' by Dr. Gustav Simon, entitled 'Die Hautkrankeiten durch anatomische Untersuchungen erliutert,' Berlin, 1851. As it would have been quite out of the question to have quoted all the authorities referred to by these writers, or to have entered into a discussion upon the grounds for the views advanced, I have stated what seemed to me the most probable opinion on the subject where these writers do not agree. 340 THE SKIN the nail: the paler portion is called lunula. The rate of growth of a nail does not seem much affected by disease, but its thickness is diminished by any cause which reduces the strength of the system; and this difference is easily seen by inspecting the nail, that part of it which has been formed during illness being separated by a transverse line from the remainder. Hence, as suggested by M. Beau,' if we know how much a nail grows in a given time, we may calculate by this line which divides the healthy from the sick what has been the duration of a chronic illness. He maintains that the nails of the hands grow four times as fast as those of the feet. The former grow one millimetre a week, and as the length of the thumb nail is twenty millimetres it takes twenty weeks or five months to attain its full length, while that of the great toe requires ninety-six weeks or nearly two years to complete its growth. Thus, for example, a groove situate five millimetres from the distant end (allowing three millimetres to the covered part) dates the attack of illness at eight weeks back; and about the time the thumb nail has outgrown its power to afford information, the mark on the nail of the toe is just be, coming visible, and this lasts for two years. Dr. E. Wilson tried the test upon himself, and found it approximately correct. The observation is at all events well worthy of attention by the practical physician. As we should expect from the nature of its structure, the diseases of the epidermis are very trifling, the most important being no other than the common corn, which ' Archiv. Generales de Med.,' vol. xi, p. 44,7. AND ITS DISEASES. 341 perhaps hardly deserves the rank of a disease. Its formation is abundantly simple, arising from the irritation caused by pressure on some part of the foot. The natural consequence of this irritation is slight inflammation of the skin, and as a consequence increased vascularity of its surface, and upon this enriched ground an excessive growth of cuticle. This growth being confined on all sides has no alternative but to shoot upwards and downwards, hence the almond shape of a corn. Sometimes the irritation of the descending root is so great as to cause suppuration, according to Rayer:1 and Sir E. Home has directed particular attention to the corns which are apt to form upon the bursae on the lower surface of the foot. He seems to have fallen into error in assigning the bursa as a cause of the corn; it is in fact its natural preventive, being placed on the points of greatest friction and pressure, which are those where corns most readily grow. Tolle causam is the only therapeutic indication for the' treatment of corns, which might in this instance be translated to give up tight boots; and when required to walk much, to extemporize an external bursa mucosa of soap and a thick worsted stocking. Almost the only change in the colouring matter in the skin which need be noticed is Chloasma, for although sunburns (Ephelis, rt Xtoc) and freckles are no doubt caused by an excess of colouring matter at spots, they are more usually remedied by cosmetics than drugs. Chloasma, called by Willan Pityriasis versicolor, is characterised by patches of a brownish yellow (maculae hepaticae) 'Theoretical and Practical Diseases of the Skin,' by P. Rayer, M.D., 2d edition, 1835, p. 991. 842 THE SKIN or saffron colour of considerable extent, frequently attended with itching, and followed by desquamation of the epidermis. In women it is generally met with on the chest and epiastrium, and in men upon the abdomen. It seems to consist of a preternatural increase of pigmentary cells, which being more friable and less adapted to form scales than the other epidermic cells, give to the surface the mealy appearance characteristic of the disease. It depends upon some derangement of the general health, in women generally on an abnormal state of their uterine functions, and the treatment therefore does not fall under the head of skin-diseases at all, although its description does. It is usual to describe the hairs in connection with the epidermis; but as their relation to the ducts of the sebiparous glands are more important in a pathological and practical point of view, we prefer postponing their history till we speak of those glands. The derma or true skin may be likened to cloth woven of fibres of different kinds, and studded all over its surface with minute eminences called papillce. The greatest part of its substance is composed of common fibrous tissue, the filaments of which interlace one another, and the spaces between are filled with adipose tissue; in the external layer of the skin yellow elastic fibres are also observed, and in those parts of the body which are covered with hair distinct muscular fibres have been discovered by Kolliker.1 The accuracy of the observation is admitted by Bowman and Erasmus Wilson, and so we may consider this important discovery established. It is 1 'Zeitschrift fiir Wissenschaftlichc Zoologie,' von V. Siebold und Kolliker, 1 Bd., 1 Heft., 1848, ~ 48. AND ITS DISEASES. 343 owing to the presence of these muscular fibres that the erection of the hairs in cutis anserina takes place. The papille are so many little nipples as it were drawn out of the upper surface of the skin. In the more sensitive parts of the body they are arranged in small clumps side by side, some eight in each clump, while in the less sensitive portions they are scattered irregularly. This accounts probably for the fact that in some parts, as the finger, if two points at a slight distance from one another be pressed or pricked, say with a pair of compasses, it gives rise to two distinct sensations; whereas if spaces at the same distance apart be similarly experimented on in other places of the surface, the sensation of only one prick or pressure is produced. Into each papilla composed of fibrous and elastic tissue, and padded all round with fatty support, there enters a nerve and blood-vessel. In those papillae which are for touch, the nerve terminates after forming a loop at the top, and the blood-vessel also after a tortuous course ends in a loop. So that these rows of highly injected elevations, thus amply supplied by nerves, are a kind of erectile tissue, which expand themselves to their full stretch when we exercise the faculty of touch, and lose this fine power almost entirely when flaccid from cold or other causes. Man possesses the faculty of touch in much greater perfection than any other vertebrated animal; but among the lower classes in which the other senses are either imperfect or altogether defective, this remaining sense is given in compensating abundance, and in some it is so exquisite, that, according to Cuvier,1 they S Cuvier's 'Lectures on Comp. Anat.,' vol. ii, p. 551. 344 THE SKIN are able by it to perceive light, so that a certain fulfilment is given to the melancholy demand of our great blind poet when he says-- Since light so necessary is to life And almost life itself, if it be true That light is in the soul, She all in every part, why was this sight To such a tender ball as the eye confined, So obvious and so easy to be quenched, And not as feeling through all parts diffused, That she might look at will through every pore? Samson Agonises. It is natural to expect that living boundary which separates the world within us with its multitudinous and incessant operations from that without us whence all the materials for the works are derived, the great medium of intercourse between these two allied yet distinct creations, which may also be regarded as the sky of the mind, growing pale from grief, fear, and dismay, flushing red in hope or joy, glowing crimson in shame, and turning even livid in intense rage, should be the seat of as many morbid appearances as the number of its uses is great and various. To enter here into a minute detail of each would be manifestly impossible, all we can hope is to describe an example of the most characteristic forms of these alterations, and seek in the light afforded by investigating the laws which regulate their successive changes, a guide both to their arrangement and to that of their remedies. Inflammation of the corium may be either diffused or circumscribed, and may terminate either by resolution, by effusion of lymph or pus, or by the formation of AND ITS DISEASES. 345 diseased cuticle, or some peculiar product. The diffused form of inflammation embraces Erythema, Roseola, Urticaria, and Erysipelas; the circumscribed is the origin of all papular, vesicular, and pustular eruptions, and of boils and carbuncles. In erythema the inflammatory process is so slight that there is scarcely any sensible thickening of the skin, merely redness, sometimes attended with considerable itching; after its disappearance the affected part retains for some time a purplish hue, and desquamation of the cuticle takes place. It occurs either as a symptom of some internal disorder, frequently of the mucous membrane of the bowels, in which case its seat is the abdomen, or it is caused by friction (erythema intertrigo) situated in the folds of the skin, especially of infants, and is attended with a very troublesome irritating seropurulent discharge; it sometimes disappears on one part to reappear suddenly on another (fugax), and it is sometimes attended with cedema of the affected surface (wdematosum). The other varieties (papulatum, tuberosum, and nodosum) need not detain us. Boseola is a designation applied very loosely to various slight red eruptions. The only one of much constancy and importance which is called Roseola variolosa, consists of an erythematous inflammation of the skin, which occasionally attends the fever of inoculated small-pox, appearing the second day from the commencement of the constitutional symptoms, and upon the ninth or tenth day after inoculation. A similar eruption is also met with after vaccination (Roseola vaccina). Rayer describes an eruption which he observed in cholera after the period of reaction, as Roseola cholerica. No such eruption was 346 THTE SKIN observed here as a constant symptom, and what he describes has probably been owing to accidental causes peculiar to the place-Paris, and the time-1832. Urticaria, or nettle-rash, is very well named, the whitish or red wheals on the skin bearing a close resemblance both in appearance and in the pricking, itching sensation they give, to those produced by the sting of a nettle. The disease consists of an inflammation more or less diffused over the surface of the skin, and without that amount of heat and pain which generally attends inflammatory action. It seems to depend upon some specific internal irritation, either occurring spontaneously in the system or caused by food poisonous to the person, such as shell-fish or bitter almonds. The appearance of the eruption generally coincides with the alleviation of the general suffering; hence it may be considered as a vicarious action of the skin. Its disappearance is sometimes attended with great constitutional disturbance. Willan mentions a case which terminated fatally, the improvement which had taken place while the eruption lasted being converted into violent aggravation of all the symptoms attended with delirium which ended in death, notwithstanding the reappearance of a slight eruption just before the end. Erysipelas, both in severity and frequency, is much the most important form of diffused inflammation of the skin. According to its intensity and the depth to which it penetrates does it vary in its symptoms; when slight, differing little from Erythezma; when severe, going on to extensive suppuration, and even gangrene. It is always attended with heat, pain, and swelling; when the swelling is considerable it depends upon cedema of the part, AND ITS DISEASES. 347 owing, according to Henle, to the deficient action of the absorbing lymphatic vessels. When the more superficial layer of the skin is chiefly affected and yet the inflammation severe it gives rise to blisters, and this variety goes by the name of Erysipelas bzllosum. The worst form is the phlegmonous, which spreads a gangrenous destruction even below the skin into the areolar tissue and subjacent fascice. The causes of the disease are little known-it certainly occurs much more frequently in certain seasons and in particular localities than in others. It is alleged to have a strong affinity with puerperal fevers, and that these two have the power of reciprocal propagation.2 From whatever source derived, and whatever form it assumes, it is always attended with considerable, often severe, constitutional symptoms; and, when it affects the head, is a disease of great danger. According to SimonS and Sch6nlein the urine is affected at an early stage of the disease, frequently being loaded with bile-pigment, and of a reddish-brown or red colour. It is generally easily recognised by the rigors which usher it in, and the quick hard pulse, nausea, and general malaise which precede the appearance of the characteristic eruption. Diffused inflammation of the skin gives rise also to a superabundant development of cuticle, which is sometimes likewise unnatural in structure. Hence arise the squamous.diseases, Pityriasis, Psoriasis, and Pellagra. The first of these, pityriasis, consists merely of excesS See a case related by Dr. Wielobycki, in the 'British Journal of I-Iomceopathy,' January, 1852. 2 Ranking's 'Abstract of Med. Science,' vol. iv, 1846. 3 Simon's ' Animal Chemistry,' vol. ii, p. 278. 348 THE SKIN sive desquamation, and occasionally occurs in phthisis from the imperfect nutrition afforded to the dermoid tissue which shows itself in the curved and weakened nail, characteristic of that malady. It may be a question whether the exfoliation of cuticle in this disease be always the result of inflammation of the subjacent tissue; in certain varieties (p. rubra) it certainly is so; in others, and these the more common, there is little appearance of any vascular change in the skin;-however, Hebra, a great authority in this matter, does not allow any distinction of kind between the rubra and other forms. At all events, the cause of the disease is unquestionably some change in the corium which induces too abundant a crop of insufficiently formed epidermic scales. It may affect any part of the body, and the predisposing causes are but little known. Psoriasis, called also lepra, differs rather in degree than in kind from its predecessor, except that the papillae of the skin are here enlarged so as to look like worts in some cases, and the cuticular scales are more changed, being loose in texture, which gives them a shining silvery appearance characteristic of the disease. The amount of these scales rubbed off in the course of the day is sometimes very great, from 65 to 385 grains in one case, related by Henle.1 The favorite seats of psoriasis are the elbows and about the knees, where it generally assumes a circular form, and when it goes off the first improvement is visible in the centre of the patch. Besides the epidermic scales which are thrown off, there is too great a secretion of the intermediate semifluid sub ' Prager Vierteljahrschrift,' iii, Bd., ~ 104. AND ITS DISEASES. 349 stance on which these grow, which produces a moist state of the skin after their exfoliation, and there is often intolerable itching of the affected parts. It receives different names according to the different parts of the body it affects-as palmaris, on the palhns of the hand -labialis, on the lips, and so on; but there is no essential difference in the nature of the affection wherever it is located, and these subdivisions seem unnecessary. It seems prone to attack persons of a gouty habit; and there is one variety commonly associated with secondary syphilis. Pellagra is a disease almost confined to the northern parts of Italy. It consists of an excessive formation of cuticle generally of a brown or black colour, on those portions of the skin much exposed to the sun-rays. It is usually preceded by a manifest erythematous condition of the skin, but sometimes appears without this precursor. It is associated with a derangement in the nervous and digestive system. A papula or pimple is the first stage in most circumscribed inflammations of the skin, and the formation of this has been accurately investigated by Simon. He rubbed tartar emetic ointment upon the skin of a dog from which the hair had been shaved, and so soon as the effects of this substance had been produced he killed the animal and examined the affected skin. He found the cuticle healthy, and in the most superficial layer of the true skin a small eminence about the size of half a barley-corn. This little mound was caused by the injection of the part with blood; the injection extended to about half-way through the skin, and below this, and all round the mound there was an effusion of fluid. The 850 THE SKIN fluid resembled the blood-serum in consistence, and contained minute molecules and fat-globules. In the immediate neighbourhood of the inflamed spot there was an unusual quantity of blood, and beyond this the skin was perfectly healthy. This description corresponds with that given by Henle and Rokitansky,i and differs from that of Rosenbaumn, Hebra, and others, who conceive the sebiparous glands to be implicated in papular affections. The effused fluid may either be absorbed, and so on the subsidence of the injection of the vessels the pimple disappear, or it may be of so great an amount as to convert the papula into a vesicle, and this vesicle may in its turn be transformed into a pustule. The papular eruptions are those of measles, strophulus, lichen, and prurigo. The eruption of measles consists of roundish red spots slightly elevated above the surrounding skin, with little swelling of the integument, except upon the face. It assumes the form of semicircular patches divided from one another by unreddened skin. The cause of this peculiar form is not known, but it seems to depend upon what may be called the general geography of the skin, for the mottled appearance which it presents in healthy children after exposure to cold has the same semi-lunar aspect. Simon2 cut out a pimple produced by measles and examined it under the microscope; he found it to consist of a spot injected with blood, but perceived no fluid such as was observed in those pimples he had produced artificially; however, the absence of fluid might be accounted for by the pressure employed during the i' andbuch der Patholog. Anatomie,' Bd. ii, ~ 90. Op. cit., p. 124. AND ITS DISEASES. 351 operation, and it is most probable that the elevation of the spot depends upon the presence of an effusion. The cuticle adhered to the skin in a healthy manner, and there was no increase nor any unnatural appearance in the papillae of the skin. All the spots he examined were p erforated by a hair, the ducts of which were healthy, and he adduces good grounds for disbelieving that the sebiparous glands are connected with this eruption, an opinion maintained by some writers on the subject. The eruption generally appears onl the fourth day of the fever, and is attended with heat and itching; in children with a very delicate skin it sometimes occurs onithe third day, and in those exposed to cold it may be as late as the fifth or sixth. In ordinary cases it reaches its height on the seventh day. It appears first on the face, then on the trunk, and lastly, on the limbs, and recedes from the sixth day of its invasion in the same order of march. Of the general disease of which the eruption is the symptom it would be out of place to speak here, it demands attention now only because it furnishes pimples which rise, and grow, and fade according to the same laws which regulate other pimples. Strophubts is an eruption of small pimples diffused either partially or entirely over the body of infants. It.is known by the name of red gum or gown, and is unattended with constitutional symptoms of any kind. There are various varieties (intertinctus, conferlus, candidus, &c.), but the pimples which form the essential character of the disease are the same in all. ]_iclien (from XEXrnv) is closely allied to strophulus, but affects persons in adult life, while the other confines itself to infancy. It consists of an eruption of conical 352 THE SKIN pimples of a red or natural colour over a part or the whole of the surface of the body, attended with tingling and itching. The most remarkable form of the complaint is the Lichen tropicus or prickly heat, which is described by Dr. Winterbottom in a letter to Willan, from personal experience, as consisting of munerous papilla about the size of a pin's head of a vivid red colour, and attended with intolerable itching, and the sensation as if a number of pins were piercing the skin. Dr. James Johnstone says-" The sensations arising from prickly heat are perfectly indescribable, being compounded of pricking, itching, tingling, and many other feelings for which I have no appropriate appellation." Prurigo, although sometimes an eruption of pimples, more frequently consists of induration of the derma in small flat elevations, caused by the swelling of the little angular compartments between the lines traced upon the skin. Its diagnostic peculiarity, as the name implies, is excessive itching. Mr. E. Wilson ascribes this itching to a disordered condition of the nerves, and attributes the affections of the skin to this as a consequence; sometimes it may be and is, but manifestly the cutaneous disease produced by neglect of cleanliness, is the cause and not the consequence of the nervous derangement; and the inference he draws that the ducts of the glands and hair-tubes are primary seats of morbid action seems unwarranted, and is denied by Simon on the strength of microscopic inspection of the parts. Simon finds no difference between the essential character of the eruption in p'rurigo from that of the two other papular eruptions. The pimple instead of being conical is a flat table of AND ITS DISEASES. 353 skin thickened by excessive vascularity, and probably also by some effusion into its substance. The sufferings produced by this disease are dreadful; patients describe themselves as being tormented " with burning fires, maddening itchiness," and an unfortunate ecclesiastic, " un malheureux eccl6siastique," as Alibert1 calls him, thus expressed himself-" Je suis sur le gril et j'endure le martyre de Saint Laurent." A still more dreadful form of the complaint is characterised, according to Cazenave and Schedel in their excellent treatise on skin-diseases, by the generation of countless pediculi or such-like animals whenever there is cover for them to lodge themselves. They call this revolting variety of the disease prurigo pediculaire, and describe it as usually affecting old people, but give an example of its occurrence in a young woman in Biett's ward in the hospital of St. Louis. This species of the disease is denied, both by Mr. E. Wilson and Simon, but, as it seems to us, on insufficient grounds. That it usually attends unclean habits is true, but it is equally certain that it sometimes affects those whose position render such an origin impossible; and that it was known among the ancients, by whom it was attributed to the anger of the gods, and who were notorious for their attention to cleanliness, especially the Greeks. It is supposed to have been some form of this malady which terminated the criminal career of Herod Tetrarch of Galilee. When an effusion of serum takes place upon the surface of an inflamed spot then a vesicle or blister is formed, and, according to the size and arrangement of 1 Alibert, op. cit., p. 703. " 'Abr6g6 Pratique des Maladies de la Peau,' Paris, 1828, p. 283. 23 354 THE SKIN the vesicles so formed, the affection of the skin assumes various well-marked appearances, constituting the diseases called-Bullce and Vesicule. The most important of these are-Pemphig us, Rupia, Herpes, Eczema, iIiliaria, Scabies, and Varicella. Pemphigus (rewt+, a bubble), and Pomph olyx (ropooXv, a water-bubble), for these are merely varieties of the same disease, is a blister varying in size from that of a split-pea to a hen's egg, situated on an inflamed base somewhat smaller than itself, filled with fluid at first transparent and yellowish, afterwards pinkish, sanguineous, and turbid, which is discharged by the bursting of the confining cuticle, and a thin dark crust remains. These blisters generally occur in successive crops, often unattended with constitutional symptoms, are either local or general on the surface, and last from a few days to several months or even years. When chronic it is often associated with prurigo, particularly in old people, and excites such distressing irritation as sometimes to cause death. The blisters sometimes extend to the mucous membrane of the mouth; and in a case related by Rayer which he attended, the inflammatory process involved the intestines and bladder.' The disease seems sometimes to be vicarious with pulmonary affections. Rayer mentions an instance of hemoptysis disappearing on the occurrence of an attack of Pemphnigus, and adds, that the sudden disappearance of this eruption is attended with danger to the constitution. It is generally connected with some disorder of the gastro-intestinal system, and Biett frequently found fatty degeneration of the liver in 1 Rayer, op. cit., p. 214 AND ITS DISEASES. 355 those who died of it. Mr. E. Wilson' mentions a case which seemed produced by some mercurial preparation; it occurred in a girl of twenty-two years of age, who had " poisoned " her hand some years before in cleaning brass with a red paste (mercurial?), and from that time to the date of Mr. Wilson's inspection had been affected with ecchymosed spots and bladders on the wrist and forearm, which he attributes to the poison. If he be correct in his inference, the case has great interest for us in many ways. ]Rupia (puTroc, sordes) is a modification of pemphigus, which occurs in persons of cachectic and debilitated constitutions. It consists of small flattened blisters, few and dispersed, each surrounded by a narrow red ring. They contain a fluid, at first serous, but soon sanguinolent or purulent, which leaves on its escape dark greenish or blackish rough crusts. The larger ones look somewhat like an oyster-shell, the smaller like that of a limpet. When the crusts fall off they leave behind ill-conditioned ulcers, which discharge much ichorous fetid fluid, and are indisposed to heal. Rupia is tedious in its course, and lasts for several weeks or months. The most formidable variety of the disease is called ]Rupia escharotica, known in Ireland under the name of CC white blisters," "eating hive," and "burnt holes."2 It attacked the ill-fed children of that once wretched country. Sometimes it is preceded by a general livid colour of the skin, but more frequently the blisters are the first indication of the disease. These are a little larger than the pustules of smallpox, discharge a thin 1 Op. cit., p. 191. 2 See in 'Dublin Medical Essays,' 1807, a paper by Dr. Whitley Stokes. 356 THE SKIN offensive fluid, and leave behind a painful spreading ulcer with livid edges. It often affects the head, destroys the ears and the eyes, and terminates in death, preceded by convulsions or general lividity, upon the tenth or twelfth day of the attack. We are not aware whether this dreadful disease still occurs in Ireland. It was always confined to certain localities, and it is to be hoped that it will disappear as the general amelioration of that opprobrium of this empire advances. Closely allied to Rupia is Herpes (wTrE,, to creep), which is an eruption of clusters of small globular vesicles upon inflamed patches of irregular or rounded form and of small extent. Each vesicle takes about ten days to complete its course, and ends by absorption of the contained fluid or by rupture of cuticle, and the formation of a brownish scab which soon falls off. In some forms of the disease, Herpes p/hlyctenodes for example, the vesicles assume no regular arrangement, but are scattered in groups of various forms over the surface, and the complaint receives its specific appellation from its seat, being called labialis, palpebralis, preputialis, and pudendalis, according to its occurrence in the various localities indicated by those adjectives. At other times it assumes regular forms, constituting Herpes circinatus and Herpes zoster. In the former the vesicles form rings, and the disease is called vesicular ringworm. Herpes zoster, or shingles, consists of a belt of little globular blisters, which generally -extend round half the body. From the time of Pliny it has been a popular belief that if the girdle completed the circle of the body death ensued. This seems to be an error. It generally occurs about the middle of the trunk and extends up AND ITS DISEAsES.' 357 towards the shoulders behind. There seems good grounds for adopting the opinion which Simon1 is inclined to, that this disease has its origin in some affection of the nerves; and that the form it assumes depends upon the distribution of their underlying branches. Whether this be so or not, there is no doubt that it is both preceded and followed by severe neuralgic pain; and we know one instance, in which neuralgia of the side which commenced in an attack of Herpes zoster has continued to afflict the patient for ten years, notwithstanding every variety of remedial measures which the whole faculty allopathic and homoeopathic could suggest. There is another rare and remarkable form of this disease called Herpes iris, from being composed of consecutive rings of different colours. It is generally about the size of a shilling, and the innermost ring is reddishbrown, the second from the centre yellowish and somewhat elevated, the third vivid red, and the fourth of a pinkish hue which gradually shades off into the colour of the surrounding skin. It may appear on any part of the body, but has been most frequently observed on the face and hands and round the joints. It usually lasts from ten to twelve days.2 In the various vesicular diseases hitherto mentioned, the vesicles remain for the most part separate during their whole course from their origin to their decline. This is not the case however with Eczema. Eczema (eKýCiv, to boil out) consists of an eruption of numerous minute vesicles tending to unite. It spreads over a large 1 Op. cit., p. 186. 2 See a paper by Dr. Marshall Hall, in the ' Edin. Med. and Surgical Journal.' 358. --THE SKIN space, and terminates either by absorption of the fluid, or by moist excoriations ending in thin crusts, or furfuraceous desquamation. It is prone to affect those parts of the body which are covered with hair. It is sometimes attended with considerable inflammation of the skin, Eczema rubrum; and the fluid of the vesicles in one form of the disease, Eczema imnetliginodes, becomes converted into a turbid perulent secretion, which is effused upon the surface of the skin, and hardens into yellow lamellated crusts, which when removed leave the skin of a vivid crimson colour, coated here and there with films of whitish lymph, and secreting a quantity of ichorous fluid of a reddish tint. When clhronic, the subcutaneous tissue becomes dense and marked with numerous chaps and fissures, from which there constantly oozes an offensive discharge. This form is attended with severe itching, which in some situations, as the anus and vulva, become quite intolerable, and is aggravated by the patient's fruitless attempts to relieve it by scratching. A very frequent and troublesome variety of this disease is met with in the heads of children, Eczema capitis; it consists of numerous vesicles which form about the roots of the hair, but are not perforated by them, when.it continues, by the bursting of the vesicles and the discharge of their contents, the hairs become matted together at their roots, and then thick yellow crusts are formed, which are gradually raised from the scalp by the growth of the hair at the edges first both before and behind. When chronic it may be either moist or dry, according to the quantity of discharge; both varieties are met with in the same scalp, and they pass insensibly 1 See a 'Practical Treatise on Skin Diseases,' by J. E. Erichsen, 1842. AND ITS DISEASES. 861 - cording to Hebra1 who has written an admirable paper upon the subject, to the prevalence of the humoral pathology and the influence of Autenrieth and Hahnemann, the whole notion of the itch insect fell into neglect and disrepute, and came to be looked upon as fabulous; so that even as late as 1812 we find that Rayer and Biett, who were supposed to be among the best dermatologists of the day, were against the opinion. At this time, an apothecary of the name of Gales played a memorable hoax upon the learned world. He gave out that he had at length discovered the insect, and went the length of sending a lot of them, which he asserted he had picked out of the skin, to the French Academy. All the philosophic eyes were directed to scrutinize the long sought and at last found tormentors of our race, and Gales for a time was hailed as a discoverer. Soon, however, it was observed that there was a marvellous similarity between these insects and meal-mites, the hoax was admitted, and the learned world relapsed into more secure incredulity than before. At length, a student from the island of Corsica, who had been in the habit of seeing the insects taken out of the skin at home, came to Paris and instructed the great Dr. Rayer, of La Charit6, in the simple and popular mode of digging out the acarus from its lair. After this time, the little insect may be said to have been promoted to a scientific degree, as the learned men owned its existence and gave accurate delineations of its appearance. The best account we have seen, of the progress of the disease from the first appli. cation of the insect, is that given by Dr. Adams in his 1 ' Medicinische Zabrbiicher,' 1844. 362 THE SKIN work on 'Morbid Poisons,' first published in 1801, at a time when the connection between the itch and the insect was not generallybelieved, in. Whenin Madeira, he says' "C In July, 1801, I procured two oug6es (the Portuguese name for the itch-insect) from the young woman whose aunt consulted me for the cure of her niece. The old woman, without spectacles, which she always used when working with her needle, but not without much diligence and nicety-extracted them from the girl by means of a pin, and placed them between the fingers of my left hand, the skin of which, and I believe of my whole body, was entire. They remained without any disposition to move as long as I watched them, but on examination two hours after, nothing was to be discovered but a small desquamation of the cuticle. " For more than three weeks little or no inconvenience was felt. From that time began frequent itching in different parts of my body, but no eruption could be discovered. In less than a fortnight afterwards, my arms and belly were covered with a general efflorescence but few vesicles appeared. I applied to my old woman, who readily drew two ougois from my arm, but not from the vesicles, indeed on this and on all other occasions I could not help remarking that although I could not discover what the marks were by which she was directed, yet she constantly passed over the vesicles without suspecting them to be the nidus of the insect. At length, I perceived it was a small, slightly discoloured elevation of the cuticle, which appeared as if soon to be 1 Adams on 'Morbid Poisons,' p. 295. AND ITS DISEASES. 363 vesicular, that the woman always attacked, but not always with success. However, she constantly answered to our inquiries, that where the bladder was formed the ougao had left the spot. " No remedies being used, nor any alteration in diet or my usual habits, the weather also being warmer than common, even for this season of the year, the disease continued to spread rapidly, so that by the end of August my whole body, arms, and thighs, were covered with the efflorescence. As, however, the Vesicles were few, I was willing to believe the eruption might be the prickly heat. On this subject I applied to the old woman, who confirmed my suspicions, but there is reason to believe I was not sufficiently cautious,in leaving my teacher to form her own opinion before she had discovered mine. In the mean time, my health suffered exceedingly, not only from the inconvenience produced by the itching; but about noon a quotidian fever began, with a slight shivering, and was succeeded with headache, dry heat, great thirst, loss of appetite, and considerable exacerbation of the itching. The consequent perspiration was not greater than what the season, might have produced. cc So little was I prepared to expect such effects to arise from such causes, or so determined to ascertain the cause, that to allay the itching I used an ointment of pomatum and saccharum saturni, from which some relief seemed to follow. It was, however, for a short time, and the paroxysm of fever being as regular, though much slighter than in common ague, I had recourse to the bark. If this produced relief it was very temporary. "By the middle of October the efflorescence was uni 364 THE SKIN versal over my abdomen, and very general over my arms, breast, and thighs; my hands were only slightly affected, but sufficiently to be detected by the natives. The character was indeed here more strongly marked, for the white shining cuticular elevations were such as I should not have scrupled in England to call the itch. "About this time, one of my family became slightly infected with the eruption; but her fever was very considerable. It seemed, therefore, reasonable to attribute all my own symptoms to ouc6es, or at least it was time to try whether by ridding the skin of them, the other symptoms would cease. The ointment I had invariably found successful in all other cases was composed of a drachm of white precipitate of mercury and an ounce of soft pomatum. The effect of this on us both was almost incredible. In three days time the itching nearly ceased and the fever entirely. However, it was found necessary to have recourse to the ointment occasionally for nearly a month afterwards; little cuticular elevations and some vesicles arose at different times during that period, and when they arose were constantly attended with symptoms of fever. From that time we felt no further occasion for any remedies. " In the mean time, my friend Banger had began a similar experiment upon himself. He borrowed a single ou09en of me, and its multiplication soon showed itself. The first parts in which he discovered either itching or eruption, were the inside of his left arm, near the axilla, and part of the chest which comes in contact with it. This he imputed to his habit of sleeping with his right hand in that position. At first, he used no means of cure but warm bathing. He next tried dry friction of AND ITS DISEASES. 365 brimstone over such parts only as showed the eruption, or gave the sensation of itching, and gained some assistance from them, but was not cured without a sulphur ointment; and the efficacy of this was slower than I have usually found from the white precipitate ointment. " My friend Mr. Banger brought a child to his house much covered with the disease, that he might learn to extract the insect himself. He was so diligent in the lessons he received daily from an old domestic, that in about six weeks the child afforded no more oug9es, though all remedies were carefully avoided." Dr. Adams gives a very accurate description of the exact spot where acarus is to be found. He concludes his paper by a series of reasons against the identity of the disease engendered by these insects and true itch, but refutes himself unconsciously by giving an excellent delineation of the insect, which, on examination, turns out to be the true acarus scabiei. Rayer, a competent authority, says of them, " Adams has given two good figures of the acarus." I There is now no longer any doubt of the existence of this little beetle called acarus scabiei, and that it has been burrowing under the skin of our race for centuries; nor is it doubted that wherever this insect is, there is true itch. Whether itch may exist without the acarus is another question. The experiments of Adams and others seem to establish that the acarus is of itself sufficient to produce the itch in a healthy individual; but it by no means follows that the itch would subside if all the acari were removed, or that there can be no itch without an acarus. At the same time, it is highly pro 366 THE SKIN bable that in all cases of true itch the acarus has been present at some stage of the disease. Hitherto, they have been found chiefly, if not solely, upon the hands, forearm, feet, and scrotum, thorax, and knee; and they are always at the very end of their tortuous passage. They are truly progressive, always going forwards and never returning by the way they came, which may account for their affinity with the inhabitants of Scotland. When taken out of their hiding-hole they leap like a flea, and give the same sensation as that insect when crushed between the thumb nails. The itch, then, seems to have a truly local origin; at its commencement it is always vesicular; it is never developed spontaneously, but always by infection; it takes from two to five days to form in children, and from ten to twelve days to form in adults, and it advances more rapidly in the young, vigorous, and sanguine, in whom alone it becomes complicated with impetigo and ecthyma, than in weak, ill-nourished people. This we state on the authority of Biett, whose position at the Hospital of St. Louis, gave him the best opportunities of investigating the disease. These facts are greatly in favour of the opinion that the insect is the true cause of itch, for if the disease were inoculated by the insect merely-that is to say, if there were a true itch virus, which when brought into contact with the circulation produced a vesicular eruption which afterwards spread-then we should expect to find that the same length of time was required for its development in all individuals; at all events, it is against all analogy that there should be so great a difference as two to twelve days. We have besides numerous direct AND ITS DISEASES. 367 experiments made by Hebra and others, the uniform result of which was that the inoculation with the fluid of the itch-pustule in no case gave rise to more than one single vesicle, and often not even to this; while the insect to the skin in the great majority of cases produced the disease. Itch is a disease to which both sexes, all ages and ranks, in all climates, are liable; but it prefers youth to old age,'spring and summer to winter and autumn, the temperate to the other zones, and the male sex is more liable to it than the female. It never subsides spontaneously; and, although limited to a small part on its first appearance, soon spreads over a large surface of the body, and ultimately may cover the whole of it. At first vesicular, it may become pustular, and from first to last it is attended with intolerable itching, and is altogether a very filthy and loathsome disease. Varicella, although strictly speaking a vesicular affection, has so many relations with smallpox as to be classed along with it generally, and by many to be considered merely that disease arrested in its development. It begins with small red papular spots, on which vesicles about as large as a barleycorn rise; these are filled with fluid, at first clear, afterwards turbid, but never fully purulent. At the end of a few days, four or five, the vesicles dry up into brownish scabs, which fall off in a few more days; and neither during its invasion, progress, or decline, is the disease attended with serious constitutional symptoms. The strong fact against its being a form of smallpox is, that the contents of the vesicles when introduced into the skin of another person never cause small 368 THE SKIN pox, rarely any regular action, and, if any, vesicles similar to those of varicella.1 The transition from the vesicular to the pustular diseases is very natural, for all pustules begin in vesicles, and all vesicles tend to assume some amount of purulent transformation of their contents. The most important pustular diseases are Variola, Ignpetigo, and EctJiyma. We omit vaccinia, as not being, properly speaking, a disease incidental to man, but only artificially produced for a specific purpose, and therefore not requiring treatment. Variola or small-pox is, in a dermatological point of view, an acute inflammation of circumscribed portions of the skin, the inflammation beginning at innumerable points all over the surface; these points are at first red, then they rise into pimples on which flattened and umbilicated vesicles form, and then transform themselves into pustules, and end in hard brown scabs. The pustules sometimes unite, and the disease then becomes confluent smallpox. The cause of the umbilicated appearance of the vesicles, which is characteristic of the disease, and appears on the third or fourth day, has been a subject of much discussion, and there is as yet no satisfactory result attained. On the whole, the most probable opinion seems to be that on the summit of the pimple an exudation either of plastic lymph capable of forming a false membrane, or simply glutinous serum entangling epidermic scales is formed, this secretion spreads from the highest point of the pimple over the surface, and binds the cuticle to the cutis, when the I Naumann, ' Hanbuch der Med, Klinik,' Berlin, 1831, Bd. 3, 1 Abth., ~ 649. AND ITS DISEASES. 369 serum which forms the contents of the vesicle is forced out by the skin, it meets with greater resistance at this point than at any other, and when the whole lid of the pimple, so to speak, is raised, the centre is for a time detained by bands of the deposit and prevented rising so quickly or so high. This layer which coated the skin and cuticle, afterwards forms a transverse partition of the pustule, broken at the edges so that the two chambers comiilunicate. In some instances, no doubt the depression is caused by the centre of the vesicle being anchored to the skin by a hair-tube, but this is not always the case, as some writers assert. The suppuration begins on the sixth day of the eruption, and is complete on the eighth; on the eleventh the pustule bursts, and some of its contents escape. After the escape of the pus from the pustule the desiccation begins, and crusts of hardened secretion form over the little ulcers left behind by the destructive inflammation. The ulcers heal by cicatrization, and in severe cases the true skin gives place to a multitude of scars, which remain a deformity for life. For scars are a sorry substitute for the natural envelopment of the body, and hence the vast importance of preventing a disease whose cure at the best is often so imperfect. A similar step which leads from viaricella to variola conducts from eczema to impetigo. Inpetzio (ab impetu, according to Pliny) is a subacute inflanimation of the skin, characterised by an eruption of small hemispheroidal or flattened pustules on a slightly inflamed base, which burst in the course of three or four days, and are succeeded by a rough yellowish transparent crust of considerable thickness. The pustules may be either sprinkled 24 370 THE SKIN (/. sparsa) over the surface without any definite arrangement, or may be of a circular or other well-defined figure (I. figurata.) In the affected part the cuticle is absent, the vessels of the true skin injected, but the hair and glandular apparatus is generally quite healthy.1 The most important variety of the disease from the frequency of its occurrence and the annoyance it produces is lipetigo capitis, called also Crusta lactea, or the milk-crust of young children. It is attended with severe itching, and the scratching thereby provoked breaks the crusts and fissures the surface of the skin, over which a viscid seropurulent discharge exudes. On the removal of the crusts the red and shining skin below is gradually invested with its natural epidermic covering, and no permanent injury is sustained, for the baldness which this disease produces, as it does not arise from the destruction of the hair-bulbs or glandular apparatus, is merely temporary. Like other eruptions on the scalp, it is sometimes vicarious, and its sudden stoppage is dangerous. -Eciymaa (,KOdEv, to burst forth) consists of an eruption of round prominent pustules of considerable size, upon any part of the body, attended with sharp pain, and is either acute or chronic. It begins, according to Rayer,2 in a conical elevation of the coriumn at the apex of the cone serumn and pus are effused, which gradually extend over the whole surface of the tumour, and then a membranous deposit takes place in the centre; after the pustule bursts a small ulcer remains, surrounded by hard, thick, puffed edges, and this ends in a cicatrix whose 'Simon. SOp. cit., 530. AND ITS DISEASES. 371 centre corresponds to the point where the deposit took place. It may be artificially produced by Tartrate of Antimony,1 and is so often caused by bad food that one variety is called Ectymna cachecticum. In the well-known experiments of Dr. Stark, who lived for some time on nothing but sugar, an eruption like Ecthyma made its appearance. The pustules produced by Tartar emetic have sometimes the umbilicated appearance of those of smallpox, probably from the same cause. The morbid affections of the skin hitherto described have been confined to its surface, those which follow involve the deeper structures of that organ. And first may be taken boils and carbuncles. i1zrunculm and Anttrax are essentially the same, they both cbnsist of an inflammation of the corium and subcutaneous cellular tissue, which terminates in the formation of a deposit, called in German, Pfropf This deposit is composed chiefly of the matter identical with the fibrine of the blood.2 Round this as a centre, suppuration takes place, and if there be but one pfropf the result is a furuncle or boil; but if there be several, then a carbuncle or anthrax is formed. In the course of the suppuration these pfropfs become separated, and not unfrequently the whole of the tissues become involved in gangrenous destruction.8 The hairs and glandular apparatus still remain to be described. The hairs are planted obliquelyin their sheaths; these sheaths are pouches of about a tenth or twentieth of an inch in length, somewhat larger at the shut than at the 1 Simon and Helbert, de exanthematibus arte factis. 2 Ascherson, in Casper's ' Wochenschrift,' 1837, s. 729. 3 Rokitansky, ' Handbuch der Pathol. Anatomic,' 2 bd., s. 89. 3729 THE SKIN open end. They are formed of three layers; the most external consists of cellular tissue, that next the hair of a clear membrane, and between these there lie muscular fibres; the bottom of the pouch is spreadwith minute granules and cells which afford nourishment to the hair. The hair itself is composed of three structures, the outermost consists of epidermic cells arranged so that the lower overlap the upper, like the tiles on a house; the next is composed of two sets of fibres, one like ribbon, the other like threads; they form the bulk of the hair, and extend downwards from the point to the root, which bulges out, and there the fibres are more separated, like the sporules of a plant. The central part consists of medulla or pith, which is composed of a cellular structure containing fluid or air. According to the most recent investigation of Griffith and Steinlin, it is upon the presence of these little airbladders that the colour of the hair depends.' The sides of the hair are not in immediate contact with its pouch, but a membrane, of the nature of which there is still some difference of opinion, lies between them and unites them. In each hair-pouch or bulb there ends the duct of a sebiparous gland, so that the hair is continually lubricated from this little oil-vessel. These glands are lobulated and imbedded in the substance of the skin, the several ducts from the different lobuli unite into a main trunk, which terminates generally in the hair-pouch, sometimes on the surface of the skin. Thus it will be seen that the ducts of these glands and the hair-pouch form a common cavity, and hence it is sometimes difficult to determine which of these organs is at fault in the 1 'Zeitschr;ft fur ration. Med.' von Henle and Pfeufer, ix, ii, s. 320. AND ITS DISEASES. 373 morbid alteration of the part. The number of these glands is very great, according to a calculation of Chevalier's, there are 120 millions of them on the surface of the body,' and this fact alone, independently of the diseases we shall presently see to be occasioned by any obstruction in their ducts, is sufficient to impress us with the importance of employing efficient means, by washing and rubbing, to maintain this vast apparatus in a healthy state. It may suggest the inquiry, whether we have done wisely in giving up entirely the use of oil, which the ancients employed so largely upon the skin, since the soapg which has superseded it is valued rather for its detergent properties in cleansing the exposed parts of the body than for any unctuous qualities by which the skin might be lubricated. It would be well for those who devote attention to the restoration of health by the use of water, exercise, and such like methods, to be familiar with the means by which the Greeks attained to such perfection of manly vigour and beauty. The chief diseases of the sebiparous glands and the ducts common to them and the hairs, depend on an increase of their secretion, or the obstruction of the outlet in some way. Of the diseases of the chief are IckJityosis, Comeclo, 2Mfollzuscum, Acne, and Sycosis. Ickhtyosis or fish-skin disease consists of an excessive secretion of sebaceous substance upon the surface, it takes the polygonal form marked out by the lines of the skin, and forms raised crusts of considerable thickness; they adhere to the epidermic scales, and become discoloured from the impurities of the atmosphere, which naturally 1 ' Lectures on the General Structure of the Human Body,' &c., 1823. AND ITS DISEASES. 375 E. Wilson's work, who corroborates Simon's description, but objects to the name, and proposes to call the intruder Steatozoon folliculorum. Molluscumn is a tumour having the appearance and being about the size of a ripe currant; it consists of an enlargement of the sebiparous gland, or of the branches of the duct nearest to the gland, so that when cut into it is found to be composed of compartments corresponding to these divisions. According to D)r. Henderson, who has given the best description and delineation of the disease,1 the tumour has the appearance of a conglomerate gland; its substance is impacted with sebaceous matter similar to that found in Comnedones. The cells of which it consists vary much, both in form and size, but seem to be of a healthy and not a morbid character; the disease in fact appears -to be an hypertrophy of the sebiparous glands. By some it is considered contagious, this however is doubtful. It is not attended with danger, and terminates either by the bursting of the tumours and discharge of their contents, or by the sloughing out of the whole mass; when this takes place an ugly scar remains. Acne (from acqn,, as it occurs in the acme of life) is an inflammation of the sebiparous glands and ducts and hair-follicles, or of the latter alone. It is characterised 1 'Edin. Med. and Surg. Journal,' vol. lvi, 1841. 376 THE SKIN by an eruption of hard conical tumours of moderate size dispersed over the body, especially on those parts where the skin is thick. It often happens that in the centre of each of these little cones a round blackish spot is perceptible (acne punctata), which is the opening of the hairfollicle distended with inspissated sebaceous matter, which may be pressed out. The other variety, acne rosacea, is recognised by the redness of the tumours, which is not unfrequently accompanied with a varicose state of the neighbouring veins. The disease, as the name implies, generally attends particular periods of growth, and is dependent upon constitutional causes. One form is a well known exponent of intemperate habits. and vulgularly called grog-blossom. Sycosis or Mentaara differs little from acne, except in its situation being confined to those parts of the face which are covered with hair. It consists of conical elevations, at first red, then yellow, from suppuration at their apex, each of which is traversed by a hair; the little tumours on bursting form a yellow crust. The disease probably begins in the sebiparous glands, and gradually involves the hair-follicles. It is tedious, and gives a very unsightly appearance to the face. Gruby, of Vienna, describes a vegetable parasite as having its abode in the eruption of sycosis, and calls the disease iJentlarophyte.' It is doubtful, however, whether these cryptogamic plants have any etiological relation to the disease, at the utmost their only pratical interest may be their diagnostic value, nor can this be very great when Mr. E. Wilson failed to discover them. " Coniptes Rendus,' 1842. AND ITS DISEASES. 377 The morbid alterations incident to the hair itself are not numerous, but it shows its participation in various affections both physical and moral, by the sudden and marked changes it undergoes. The unhappy queens of Scotland and France, Mary Stuart and Marie Antoinette, both became gray before their execution, and one night is said to have blanched Sir Thomas More, who might well have said,"0 nox! quam longa es qume facis una senem!" We have seen a remarkable example of the opposite kind in a young lady subject to tic douloureux, whose hair naturally of a light brown colour always changes to a dark colour, approaching perfect black, after an attack of that complaint. Of the diseases proper to the hair itself the most important are, Tinia, Plica polonica, and Favus. Tinia, trickonosis furfuracea (O9pL, capellus et voaoe morbus), or common ringworm, is recognised by circular or oval patches of skin in a dry furfuraceous state, on which the hairs that grow are whitish, twisted or bent, shrivelled and brittle, some broken off near their roots, others matted into bundles and mixed with yellowishgray crusts. When the part is clean the patches look parched and the hairs dried up. Later, the spots become bald or nearly so. At the beginning of the attack a thin layer of scurf may be perceived in patches here and there, which are slightly itchy; the skin under these patches is reddish, and then the papille appear as in cutis anserina. These pyramidal eminences are the swollen mouths of the hair-follicles, which look as if they had been drawn up by the growth of the hair. 378 THE SKIN The hairs themselves are like tow bent and broken off, so as to have a moth-eaten appearance, whence the name tinia is derived. The grayish or yellowish crusts are composed of furfuraceous scales and diseased hairs glued together by the moisture which exudes from the diseased surface. The disease consists in a morbid alteration of the hair and hair-follicle. The hair instead of being only 1-400th of an inch in diameter is sometimes only 1-150th. This enlargement of size depends upon a change in the fibrous portion of the hair. The fibres of this layer which we have already described are made up of granules; the disease seems seated in these granules; they are more numerous than in health, and, instead of being in regular rows, are undulating, and new granules of a nucleated character are mixed with them either singly or in long rows. Hence the disease is very well called by Mr. E. Wilson granular degeneration of the hair. This excellent observer is opposed to the theory of Gruby and others, who ascribe tinia to a vegetable parasite; he also denies that it is contagious, and supports this opinion by some very strong arguments, which seem to us satisfactory. As the question of contagion of this disease is one of great practical importance, we should be somewhat shy in adopting the negative view, for the opposite, if an error, is comparatively harmless, but this if wrong is dangerous. Plica polonica, a disease fortunately unknown in this country, seems to be essentially of the same nature as tinia, and to consist of granular degeneration of the hairs, which are swollen with blood and adhere into a matted mass, painful to the touch, offensive to the smell, full of lice, and altogether disgusting. The disease AND ITS DISEASES.39 379 sometimes begins not at the root but about an inch above it, and aff-ects only the upper part of the hair.' Pavus is unlike all other scalp affections in that its seat is below not above the epidermis, so that it presents a perfectly dry and very slightly raised cupped appearance of a bright yellow colour. Owing to the depression of the centre of these bright crusts it gets its name favii8 or honeycomb. Erichsen 2 describes the disease as the formation of tuberculous matter in the hair-follicle, the first effect of this is to cement the root to its bed; as the formation of more tuberculous matter goes_ on the whole capsule in which the hair grows becomes filled. Mr. E. Wilson regards the af. fection as degeneration. of the epidermic cells at the period when they are in the process of formation, from the primitive granules derived from the blood. These minute bodies, instead of developing themselves by aggregation into healthy epidermic cells, become transformed into others resembling pus-cells, and present the appearance' of the stems _and branches of a plant. This change takes place at the- root of the hair, and these cells linked together fill the little vessel in which the hairs grow, and also enter like a chain into the hair itself, running up through its substance and destroying its texture as in tinia: the hair, in fact, adopts these spurious bodies into it instead of the properly growing cells it ought to receive, so it may be said to pith itself with a- spike of what may be figuratively called a plant, but what is in reality only a structure of diseased SBidder, 'MUler, A~rchiv,' 1840. O p. cit. 380 THE SKIN cells. This explanation seems to us more satisfactory than either Erichsen's or Gruby's. On the contagiousness of this disease the opinions are diverse, and the same amount of doubt, suggesting a similar degree of caution, hangs over this as over 1Tnia. Both these diseases undoubtedly are due to constitutional causes. Favus is one of the worst diseases which affect the scalp, for the bald spot it leaves behind after its cure is permanent and defies all kalydors: the reason of this is that the hair-follicle or matrix is destroyed, and no new growth can take place in it. All that remains now is to describe the sudoriferous glands, which are small oblong bodies composed of one or more convoluted tubes, or of a congeries of sacs which open into a common duct, from which the perspiration which continually sensibly or insensibly moistens or bedews the surface is pressed out. The entire length of each little tube, including the gland which is situated in the deepest and middle layer of the corium, is about a quarter of an inch. The duct and tubes are lined by an inflection of the epidermis, thicker and funnel-shaped at the orifice, and delicately fine in the interior. The number of these tubes and glands is very great, no less than 3528 having been counted in a square inch on the palm of the hand. The total length of all the tubes in an ordinary sized person if added together, so as to make one line, would be twenty-eight miles. From this fact we may form some estimate of the immense value of their function in preserving the health of the body, and of the importance of those curative methods which rely chiefly upon their power of regulating this machinery, which is so extensive and is so closely allied by sym AND ITS DISEASES. 381 pathy with all the other secreting apparatus in the system. Although we propose to adhere to the same pathological order when speaking of the treatment proper for the individual maladies, yet before doing so it may be well to direct our attention to the different points of view from which this important class of diseases may be regarded, in order to arrive at the principles applicable to their successful management. These present four aspects. First, the purely local lesions of the integument; as, for example, those which arise from the chafing of the surface, or the action of some chemical irritant on a particular part, or from the bites or stings of insects, or from the presence of insects keeping up a continual irritation. - In all such cases, the removal of the cause of offence may be sufficient to restore the injured part to its natural healthfulness. The second class consists of those diseases which affect the skin secondarily, their primary effect being upon the system at large; as, for example, smallpox. The amount and degree of cutaneous affection in this disease is a most important element, both as regards its prognosis and treatment. In fact, we may look upon the extensive pustular eruption as in some respects, independent of the original constitutional cause, depending on the special state of the skin for the conditions of its development, and itself causing a new disturbance of the system. One of the best illustrations which could be given of the power topical influences exert, in modifying the development of the eruption of a constitutional disease, is afforded by the following case related by Dr. W. Budd, in an interesting paper on the Symmetry of Disease, published in 382 THE SKIN the 25th volume of the 'London Medico-Chirurgical Transactions.'-" A sailor was admitted into the Dreadnought on account of a bruise inflicted on one side of his breech by a fall into the hold of a ship. In the course of some days he left the hospital, having recovered from the injury, but still showing a bruise-mark on the breech. A short time afterwards he was again admitted with severe febrile symptoms, which terminated in the eruption of smallpox. The pustules were discrete and very few in number all over the body, excect in the exact seat of the former bruise, and there they were extremely numerous, and for the most part confluent." We have quoted the case at length because we look upon it as full of instruction. It puts beyond a doubt the importance of studying the progress of the pustules per se; showing that their number and size are not always at least an index of the general severity of the disease, but depend upon some peculiarity of the skin; and it may be of great importance in mitigating the affection of the system to adopt local measures for moderating the cutaneous eruption. What the special means are which best subserve this purpose we shall discuss in full when speaking of smallpox; at present, we adduce it as an example of the importance of paying the strictest attention t6 the state of the skin in all diseases, which although involving the whole constitution, tend to excite a specific morbid alteration in that organ. The third class of these diseases are those in which the skin assumes a sympathetic or vicarious action, holding direct relation with some morbid condition of an internal organ. In some cases the external affection is vicarious, that is, on its appearance the other malady AND ITS DISEASES. 383 suddenly subsides, to reappear as suddenly on the disappearance of this. Speaking of the trifling complaint stroplulus intertinctus, Willan says " the papular eruption is in many cases connected with a weak, irritable state of the alimentary canal and consequent indigestion; for if it be by any means suddenly repelled from the surface, diarrhoea, vomiting, spasmodic affection of the bowels, and of the general disturbance of the constitution succeed."' Willan supports this statement, made on his own observation, by the authority of other accurate observers. In this instance the cutaneous affection is not merely sympathetic but vicarious, or, in other words, there has been a transference of the morbid action from the bowels to the skin. The subject of vicarious diseases is one of immense importance in a therapeutic point of view, as well as extremely interesting in itself, but it would be out of place to do more here than direct attention to it as one of the sources of erroneous treatment; for, as in smallpox there may be danger of our using too few local measures, there is as much danger of our using too many in this and similar eruptions. At Sthe same time, we must draw a distinction between vicarious and sympathetic affections, for while the former ought not to be hastily attacked, it may be proper to direct vigorous treatment against the latter. The distinction between the two classes is this: in the onethe vicarious-the morbid action leaves a dangerous seat of operation, such as the intestines, and takes up its abode on a part it cannot materially injure: in the other-the merely sympathetic-the disease does not I Willan, 'On Diseases of the Skin,' p. 22. 3814 THE SKIN quit its original place of settlement, but establishes besides a dependency in some other part, and the two may act not alternately to the relief, but simultaneously to the distress of the system. In such cases, of which prurigo may be taken as an example, curing the secondary disease is like crushing the colony of a hostile power. One source of mischief is quelled, and the other is abated. The remaining class consists of those diseases which depend upon the presence of some constant constitutional taint, and as they are the most numerous so they are also the most difficult to cure. A.s an illustration of this division we may take lepra, by much the most common chronic affection of the skin, and generally looked upon as quite incurable by the old therapeutic methods. The most important fact connected with this complaint for us at present is, that however inveterate or extensive the eruption may be it is easily removed for a time by medicine, which has a specific action on the skin, whether this be administered in palpable or infinitesimal doses, and thus a delusive cure effected, for after the abandonment of the specific the disease soon returns. We have long had an opportunity of watching a patient who has been subject to this disorder for about thirty years, and in him it is always cured by Arsenic, whether he take the 15th dilution or five drops of Fowler's solution three times a day; and it is remarkable that after continuing this medicine for a couple of weeks, let the quantity be ever so minute, it is apt to produce unpleasant constitutional effects. This is a good example of a homoeopathic palliative; and it was the occurrence of cases of this kind suggested to Hahnemann the important practical AND ITS DISEASES. 385 division of medicines into those which were antisporic, and those which were not. It may be that this distinction is rather confined to individual cases than fitted to express the universal relations of a drug, that is, that in one kind of disease and constitution a medicine may act deeply and so permanently as to destroy the tendency to the disease as well as its manifestation, while in other constitutions or in other conditions of the system it merely removes the phenomenal expression without eradicating the culpable element from the body. For example, we look upon Mercurius as sometimes radically curative and sometimes palliative. The palliation of an inveterate disease by its specific antidote in minute doses, and therefore acting through the system without permanently altering the constitution, is one of many arguments which might be adduced to justify the administration of medicines in alternation or succession, with the view of effecting different spheres of morbid action; for it is obvious, that if a particular substance has the power of arresting one without exerting aly influence upon the other, some other medicine may have an affinity towards that which, its predecessor did not reach, and an indifference towards that which it cured. Hence we consider ourselves fully warranted both theoretically and practically to advise the use of two distinct series of homoeopathic remedies in the treatment of diseases which arise from a constitutional taint, the one to be selected for its specific power in curing the symptoms of the disorder, and the other for gradually emancipating the system from the influence of its predisposing cause. There is another point of view in which this power of 25 386 THE SKIN palliation in what we may call local cures, ought to be regarded, and it is this: There are some cutaneous eruptions which are neither vicarious nor sympathetic, nor are they merely a part of the general disturbance of some peculiar taint, but they seem to hold the same relation to scrofulous constitutions which measles and some other eruptions may be supposed to hold good. They are what we might call the critical processes through which the system is passed, and the future health of the individual depends upon their proper management. It must have been often observed by all practitioners, that every member of certain families at some particular age, often about six or seven years old, begins quite unexpectedly, often during the fullest health and apparently without any exciting cause, to display symptoms of general delicacy; in one it may be swelling of the cervical glands, in another thickening of the upper lip or redness and swelling of the eyelids; now, if at this critical period an eruption of an innocuous kind, eczema let us suppose, appears, the chances are that it is the most favorable manifestation of the working out of the poison hidden in the frame, and the injudicious cure of this by employing the recognised antidotes to this peculiar morbid affection of the skin, may be followed by baneful consequences to the future development of the individual. We cannot but fear that this warning is not altogether unnecessary, for certainly those who prescribe according to the manuals most in repute will be almost certain to fall into the error, and it is one which may not disclose its full fruits for long afterwards, and then in some deadly and unmanageable attack of an acute disease, the cure of which is rendered AND ITS DISEASES; 387 imperfect from the disturbing force of this uneradicated morbific cause. After these preliminary observatiohs on the general principles applicable to the management of affections of the skin, we shall proceed to speak of the special treatment of the individual diseases in the order previoutsly adopted. Cloasma or Pityriasis versicolor is easily recognised by consisting as it does of brown irregular patches, distributed in a sort of geographical fashion over the body, especially the chest and abdomen, so as to present the appearance of continents and islands, with promontories and peninsulas. The only disease with which there is the smallest danger of confounding it, are the coppercoloured syphilitic or mercurial spots, but slight attention to the colour and the constitutional symptoms which distinguish the latter will prevent the practitioner committing the awkward mistake that such a confusion would be. In itself, it is a perfectly harmless blemish of the surface, the causes of which are unknown, and the only general indications for its treatment are that it is certainly aggravated, and perhaps sometimes induced by the use of flannel next the skin, especially in persons who perspire copiously. Of the long list of medicines given by Jahr as available in this affection, the only ones which bear any resemblance to it in their symptoms, or are accredited as having been useful in curing similar states of the skin, are the following: Antimonium:-" Brown spots or dots, like small hepatic spots here and there." Cocculus:" Red irregularly shaped spots on the skin, on the whole chest, and on the sides of the neck behind fhe ears, as if 388 THE SKIN coloured with red wine, without heat or sensation." Conitum:-" Chronic brown or frequently recurring red itching spots on the body." Lachesis:-" Small reddish spots on the face, neck, and arms, increase in number, become scurfy and then disappear." Ledurm:-" Bluish spots on the body, like petechia." Phosphorus:" Blotces and blotch-like spots, brownish and bueish red, as in leprous patients." Phosphorus is recommended by Noack and Trincks for the cure of brown spots on the body and yellow spots on the abdomen and chest. In one case of very extensive cloasma over the chest and abdomen of some months' standing, I found in Phosphorus a speedy cure. Sepia:-" Claret-coloured spots on the neck and under the chin, without sensation." " Brown-red hepatic spots on the skin." Erythema is diffused redness of the skin, and is sometimes a symptom of some general disorder, especially dyspepsia, hysteria and gravel; at other times it is a purely local affection depending upon irritation either of friction or of an acrid discharge. It is stated by Hippocrates to be frequently the precursor of death when it occurs in the hands and feet in any acute disease, and also in pneumonia when it appears on the chest.1 It is, however, only the second form of the complaint, known as intertrijo, that falls to be treated of at present. The parts most subject to this troublesome affection, are the axillae, the mammm on their lower surface, and the parts in contact with them, and especially the inside of the thighs, from which it extends to the scrotum, and by impeding walking is extremely annoying. It is 1 'Epidem.' lib. 1st, 89, 14. i AND ITS DISEASES. 389 often attended with a glairy secretion, with a faint sickening smell. In infants at the breast, when not well cleansed, it is frequently met with about the nates and scrotum. The first indication for treatment is obviously the removal of the exciting cause. This may be wholly effected when the mammae are the seat of the complaint by the employment of suspensory bandages, while at the same time the abraded or irritated surfaces may be dusted with starch powder or coated with arnicated Collodion. In other places, where it is impossible to avoid friction, Calendula cerate will be found a useful application. I generally employ glycerine in such cases now. Of course, the greatest attention to the thorough washing and drying of the affected parts should be enjoined. In chapping of the hands it is recommended to rub them with honey after washing and then to wipe them with a towel; this is found to be the best outward application. Warm baths, with a few Chamomile flowers in them, have an excellent effect upon that form of the disease which is met with in infants and young children. In addition to these general measures for alleviation, from among the following medicines the specific antidote for the cure may be selected. Belladonna produces "redness, inflammation, and swelling of the whole skin." Chamomilla:-" Redness of one cheek, recurring by starts without shuddering or internal heat." This is very like one of the varieties of erethyma. Besides, Chamomilla has been found especially useful in the " rash of infants and nursing females," it has also been known to cure cc sore places on the skin, especially in children." 390 THE SKIN Graplites has been recommended by Dr. Gross to be given to the nurse while Chamomilla was administered either as an external application or internally to the infant. IHepar svphulris is very effectual in curing "chapped skin and rhagades on the hands and feet," which often arise from erythema, and also in causing a beneficial change in that unhealthy state of the skin which inclines it to ulcerate on slight injuries. Oleander:-" The skin of the body very sensitive all over; it becomes sore, red and painful merely by the friction of the clothes; for example, the skin of the neck becomes so from the rubbing of the cravat, that of the thighs from the rubbing of loose trowsers when walking. Roseola:-This name has been somewhat vaguely used by writers on cutaneous affections. Rayer considers its proper place to lie between erythema and urticaria, while Willan ranks it with the exanthemata, and expresses a doubt whether it can be properly called an idiopathic disease of the skin. However this may be, all authorities agree as to the fact of the occasional appearance of an eruption, at first red, then of a rose colour, and finally becoming purple, attended with slight fever lasting about five days from its appearance, and generally accompanied with faint redness of the fauces. It generally affects children with delicate skins, especially in summer or autumn, and in some it reappears annually, which is much against Willan's opinion of its relation to the true exanthemata. Its chief interest consists of its resemblance to scarlet fever and measles; from the former it may be distinguished by its colour approaching nearly to purple, and by the mildness of the constitutional symp AND ITS DISEASES. 391 toms, for it is only in the worst forms of scarlet fever that this hue appears; and from measles by the evenness of the surface, which does not rise into papular elevations. Although a week or two would remove the trifling malady without any aid of art, yet the administration of some of the following medicines will probably assist, and certainly not impede this consummation. Aconite has been found useful in " measles and purple rash." Roseola is the only purple rash, properly speaking. Belladonna, besides its proved utility " in measles and purple rash," has also a specific action on the fauces, which are generally affected in this disorder. Sulphuric acid, although not among the list of homceopathic medicines, being highly spoken of by Willan, may be included in this brief catalogue, along with Pulsatilla and Nux vomica, which seem to be recommended by homoeopathic writers entirely on empirical grounds. Urticaria, or nettle-rash, may be ranked among the sympathetic or vicarious diseases, as it is generally produced by some derangement of the system, generally of the digestive apparatus, and not unfrequently relief is experienced on the appearance of the eruption. The affection of the skin, usually preceded by moderate fever, manifests itself in the form of an elevation of portions of the skin, irregular in size and shape, and varying in colour, being either bright red or pale, and attended with intolerable itching or tingling. The symptoms are much worse at night. The more common form of the complaint lasts for about eight days, but it sometimes becomes chronic, and continues for years. It is most frequently met with in the young, and during autumn. 392 THE SKIN The predisposing cause of this disease is evidently a peculiarly sensitive condition of the skin, for those who are liable to it can induce it at any time by pinching or irritating the surface. The exciting cause may be either of a general or specific character. Of the general causes the most frequent one is, some affection of the stomach or intestines; but instances are on record where this eruption appeared in connexion with pneumonia and pleurisy,1 and Clark met with some cases where it was associated with cancer of the uterus. Besides these very serious causes it may be excited by others of a purely nervous kind, such as mental agitation; and Dr. E. Wilson had a patient in whom he could evoke it at pleasure, by engaging her in conversation. "I have watched the red wheals," he says, "appear and creep along the skin, and disappear, while I purposely engaged her in conversation on indifferent subjects. A word, a look, the slightest excitement, would immediately bring out a copious eruption."' This case affords conclusive evidence that the notion which seems now gaining ground among the young school of pathology, of this and most similar diseases being the result of chemical change in the constituents of the blood, is erroneous. At all events, that precisely the same affections may be produced without the possibility of this presumed cause coming into operation. The specific causes are certain vegetable and animal substances which always excite the eruption; the former in a few individuals alone, the latter very generally. Among the former are sweet almonds. After eating of ' Rayer, op. cit, p. 198. " Op. cit., p. 157. AND ITS DISEASES. 393,ms fruit both Dr. Winterbottom and Dr. Gregory were attacked with urticaria.1 But the most remarkable source of this disorder, is certainl shell-fish, particularly mussels. It was a prevalent opinion that these animals became poisonous from the kind of food they lived on at certain seasons, but this is now denied by the best authorities, and the symptoms they produce are ascribed to the peculiar susceptibility of individuals. So great is this sensibility in some persons that one instance is recorded of a man who was always affected by nettle-rash if he were exposed even to the vapour of soup in which crabs had been boiled.2 However, that mussels are sometimes poisonous, from some cause or other, seems to be established by the narrative of Burrows and others, who describe cases in which death took place apparently from no other cause than eating mussels, and with all the symptoms of some violent poison.3 In the treatment of this complaint, of course if there is any suspicion of its being of poisonous origin, the first indication is to remove the cause, either by an emetic or by tickling the fauces with a feather, and giving a copious draught of warm water. However, this is very rarely necessary, for the cases of this kind are very uncommon. By much the more common varieties of urticaria depend upon a general disorder, manifesting its presence on the skin, on account of some peculiar liability of that organ to be thus impressed. 1 Willan, op. cit., p. 404. S' Med. Facts and Observations,' vol. v, p. 59. 3 I have a patient, a lady of middle age, who, if she take any exercise after eating, is attacked with vertigo, insensibility, and convulsions, which are relieved in the course of an hour or less, by an eruption of nettle-rash on the face. 394 THE SKIN The application of cold water to the affected parts, either by sponging or by the shower bath, by which means the intolerable itching is greatly relieved, is strongly recommended; at the same time we should be cautious not to induce a sudden retrocession of the affection from the skin, when its appearance has been followed by the subsidence of any internal disorder. In the febrile stage of urticaria aconite is recommended; besides its suitability to the general symptoms it produces " stinging, with feeling of soreness in various parts of the body;" also " spots like flea-bites, especially on the hands and face." Bryonia produces a train of symptoms which are the accurate counterpart of the disease: "Prickings over the whole body; a slight emotion (laughter) excites a sudden stinging itching over the whole body, as if he had been whipped with nettles, or as if he had nettle-rash, although nothing could be seen on the skin, afterwards he felt this burning when merely thinking of it, or when becoming heated; burning, itching, and stinging in different parts of the body, in the evening after lying down in bed." "Eruption on the whole body, especially on the back, extending to the upper side of the neck, itching so violently that he would like to scratch the parts to pieces." Cocculus:-"A sort of hard blotches, containing no fluid, surrounded with a red border, burning and itching the whole day, on the limbs, the wrist, and the back of the fingers." Dulcamara is strongly recommended and has been proved useful in acute iu'ticaria. It produces "buining itching, resembling the rapid crawling of insects in diffe AND ITS DISEASES. 395 rent parts of the body; he is obliged to scratch violently; in the beginning the symptom increases after scratching, afterwards it is diminished; there is little of it in the day, generally only at night, and mostly from twelve to three o'clock, after a short sleep the itching wakes him; also red elevated spots as if caused by nettles; and "red spots on the body; large and red blotches itching violently over the whole body, and on the neck: nettle-rash after violent exercise, itching for an hour." 1?hus toxicodendron produces " red spots the size of lentils, with small vesicles in the middle," and " nettlerash." Datura stramonium, although not generally recommended, may be useful, as in a case of poisoning by this substance, recorded by Dr. Meigs of Philadelphia, the face of the patient became of a deeper scarlet colour than he had ever seen it in scarlet-fever, and the neck and breast as well as the face were covered with a multitude of small spots of a brilliant red colour, many of which were star-shaped.1 Urtica urens and Cancer fluviatilis are said to be useful, but as yet there seems no very decisive evidence in their favour, and my own experience of their value from the occasional trials I have made of them, although the number of experiments was not sufficient to test the point, gives a purely negative result. When the complaint assumes a chronic form, the remedies most relied on areArsenicum, which produces " white blotches of the size 1 ' North American Medical and Surgical Journal,' January, 1827. 396 THE SKIN of lentils and having the colour of the skin, with a biting sensation particularly at night." Calcaria carbonica, among the symptoms of which we find " nettle-rash, which goes off in the cool air." Carbo vegetabilis, recommended in alternation of arsenicum, and which produces " burning in the skin, as of sinapisms in different places, the back, the sides, the side of the abdomen, &c.," as well as distinct " nettle-rash for some weeks." And Hepar sulphuris, and S&dphur, which although they do not present the symptoms of the precise eruption are useful in curing the general morbid condition of the system which engenders the complaint. The next disease on our list is Erysipelas, which is easily recognised by presenting all the usual characters of inflammation of the skin, attended with the constitutional symptoms of inflammatory fever, such as rigours, pains in the back and limbs, headache, lassitude, loss of appetite, nausea, sometimes vomiting, pain at the epigastrium and constipation of the bowels. When the attack is severe, especially when it affects the head and face, it is usually attended with considerable delirium. The duration of simple erysipelas, as contradistinguished from phlegmonous, has hitherto been from twelve to sixteen days, of which three or four days were occupied in the gradual rise of the symptoms, in an equal number they remained stationary and took the same time to decline. Even in the slighter cases, blisters of greater or smaller size appear upon the affected parts. An attack terminates in more or less complete desquamation of the cuticle. In a patient of Mr. Wilson's who was subject to an annual attack of erysipelas, the cuticle of AND ITS DISEASES. 397 the hands used to come off entire like a glove, and that of the feet like a bag or loose stocking.' Erysipelas prevails periodically in most large hospitals and lunatic asylums, so that all operations even of the most trifling kind are at such times followed by a severe and often fatal attack of the disease. In the opinion of some it becomes contagious in these circumstances, but it seems very doubtful if it be so in a strict sense of the term. It has been observed to occur periodically as a vicarious affection in some cases of amenorrhoea.2 There are few diseases in which the enormous superiority of the homoeopathic over the common empirical method of treatment is more marked than in this, so much so indeed, that our best surgeons, as the late Mr. Liston, have adopted the specific treatment recommended by Hahnemann, in addition to innocuous measures of palliation, which perhaps it might not be amiss in the present ascendancy of free trade principles that we in our turn should borrow from them. Of these, the most in vogue are the dusting of the surface with flour, or rubbing it over with lard, or lastly, painting it with Collodium, to which 1-15th part of Castor oil has been added. This last is strongly recommended by Dr. E. Wilson, who bears testimony to its practical efficacy, ascribing this to the perfect exclusion of the air, by which the generation of heat at the surface is checked and at the same time a gentle uniform pressure exerted upon the enlarged and weakened cutaneous vessels. It has also been the practice of the most celebrated surgeons to 1 Chevalier's 'Lectures on the General Structure of the Human Body,' p. 122. 2 Rayet, op. cit. 398 THE SKIN puncture the affected parts with the point of a lancet, and there is no doubt that this affords great relief, nor do we see any serious objection to the practice if it is found necessary. In the treatment of simple erysipelas it is usual to give Aconite and Belladonna in alternation, and nothing can be more satisfactory than the result of this practice. We are in the habit of employing the first, second, or third dilution of both, and of repeating the dose every two or three hours. Although the symptoms produced on the skin by Aconite do not present a striking similarity to erysipelas, yet the general febrile state is certainly mitigated by its administration, and so far from the action of the Belladonna being hindered it seems positively increased by that of Aconite. Among the symptoms of Belladonna we find " Erysipelatous inflammation, with swelling or even mortification of the parts, inflammation and swelling of the whole skin, red hot swelling of the affected parts." Rhus toxicodendron is recommended in what is called vesicular erysipelas, but as the presence or absence of vesicles does not indicate any specific change in the morbid action, and as the eruptions produced by Rhus seem essentially different in respect of the accompanying constitutional symptoms, we do not see any ground for seconding this recommendation. In fact, we believe Aconite and Belladonna sufficient for the cure of all cases of simple erysipelas. When it tends to become gangrenous other remedies are required. Phlegmonous erysipelas is recognised by the hot pulsating pain, the thickening and great redness of the skin, and the severity of the general symptoms. In severe AND ITS DISEASES. 399 cases there is gangrenous ulceration of the subcutaneous and inter-muscular cellular tissues, and the sphacelated portions escape by sinuses formed by the pus to the surface. It is generally found beneficial to enlarge these openings or to make fresh incisions, so as to allow of the removal of the dead and destructive accumulation beneath the surface. The medicines on which we place most reliance in this dangerous disease are arsenicum and lackesis. Carbo vegetabilis is also recommended, but rather upon general than special grounds, and we must confess to have been disappointed with the action of this remedy in almost all the acute diseases for the treatment of which some writers prize it so highly. Besides the medicines mentioned, we should add mercurius and hepar sullpuris to the list, and with the aid of these remedies we have seen apparently hopeless cases of this disease ultimately rescued. The scaly diseases, pityriasis, psoriasis, and lepra, are so closely allied in their pathological characters, and the lines of demarcation between the two latter at least, are so fine that it would involve much repetition if we were to give a separate enumeration of the medicines suitable for each group; so that after noting the diagnostic peculiarities of the principal diseases which are ranged under these heads and the general treatment recommended for them, we shall include the specific medicines useful for them all in one list. One of the most common forms of the first of the group is pityriasis capitis, or dandrif. It is easily recognised by the increased scurf on the scalp, which is also slightly painful and red. We have frequently found this disappear if the head is well washed with cold water 400 THE SKIN every morning and thoroughly dried with a coarse towel. The other local varieties are those which affect the lips, the palms of the hands and the soles of the feet, also a very troublesome form of the disease, attended with considerable itching, is met with in the prepuce and vulva. Lepra is distinguished from psoriasis by the more circular form of its large patches, by its preference for particular localities, especially the bend of the elbow and wrist and of the knee and ankle joints, also by the greater thickening of the skin and lighter colour of the central part of the patch. There can be no doubt that the occurrence of either of these cutaneous affections indicates a peculiar diathesis, probably closely allied if not identical with gout and some forms of rheumatism. They are frequently hereditary, and when of long standing are found so intractable as to be considered quite incurable by the old school of physic. The directly exciting causes are often simple irritation of the skin from any continued cause, such as working with flour which induces psoriasis of the hands in bakers, and a similar affection is apt to occur in shoemakers from the continual handling of waxed thread. It has been observed by Willan and subsequent writers, that when psoriasis appears on one side of the body, for example, on one leg, it is very apt to appear also on the corresponding part of the opposite side, and to present here the exact counterpart of the shape and size of the original eruption, however irregular that may be. This curious fact is much dwelt on in the essay of Dr. Budd, to which we previously referred. It seems to belong to the general AND ITS DISEASES. 401 law of the system, according to which the corresponding parts on the opposite sides of the body are endowed with vital properties so accurately analogous that all general influences traversing the system produce identical impressions on them, and thus maintain that symmetry which is essential to co-operative voluntary movement, and therefore pervades the spino-cerebral system of nerves and distinguishes it from the ganglionic which presides over the organic life, within whose sphere such combinations are not required. Besides this similarity of endowment and structure of corresponding parts, which induces the one to assume the morbid action of the other, there is probably an active reciprocal influence continually interchanging between them, so that each may be said to be in some degree responsible for the liabilities of its correspondent. We should hardly have dwelt so long upon this had it not been for the whimsical explanation given of it by one of so high and deserved a reputation as Dr. Budd. The extremely obstinate and troublesome character of psoriasis and lepra has naturally evoked an endless variety of expedients and experiments for their cure, and there is one which, although not homceopathic so far as we know, yet may be borne in mind, from the positive assurance we have had of its efficacy in a very inveterate case of the formner complaint. We allude to a soap composed of common juniper-spirit, dissolved in fixed oil and mixed with soda ley. It is now in high repute at Aix-la-Chapelle, and on it the virtue of another fashionable remedy of this disease, "Huile de Cade," is said to depend, or at least if it is not the common juniper which is used in the preparation of this oil, it is the allied species " Juniperus oxicidrus." 26 402 THE SKIN Dr. Gully recommends the wet sheet packing as generally applicable to these as well as to most other diseases of the skin, combined in this instance with an occasional sweating, and he mentions that he has thus cured some cases of inveterate psoriasis.' Arsenic, according to the experience both of the old and new school of physic, is the most eficacious remedy in the scaly diseases. "The effect of Arsenic," says Dr. Wilson," " on the leprous patches is, in the first instance, to increase their redness, activity, and heat, and subsequently to diminish those symptoms and render them brownish and dull." Among the primitive effects of Arsenic we find that " the skin of the body peels off in large scales, painfulness of the skin all over the body, prickings in the skin, itching particularly of the thighs and arms, &c." Our own experience confirms the power of this medicine as a certain specific in modifying the morbid condition of the skin when affected with lepra, so as to give at least temporary relief, and of permanently curing milder cases which do not depend upon a psoric taint in the constitution. The immense advantage of the minute doses is well seen in the treatment of such complaints, for there are many patients who are so susceptible to the poisonous action of Arsenic that they cannot take the quantity usually prescribed by allopathic physicians without the most disagreeable and even dangerous consequences, so that having only the alternative of being poisoned or suffering from a leprous skin they naturally prefer the latter as the lesser evil. Dulcamara was at one time much in vogue for the ' The Water Cure in Chronic Diseases,' by Dr. Gully, p. 402, et seq. Op. cit., p. 2S0. AND ITS DISEASES. 403 treatment of lepra. It was introduced to the notice of the medical world by Professors Althorff and Gattengen last century, and Dr. Crichton of the Westminster Hospital, writing to Willan, says "he has found it very effectual in lepra, psoriasis and pityriasis." 1 Rayer also speaks favorably of it. None of the symptoms produced by this substance correspond with those of developed lepra, but it produces very marked "cdryness, heat, and burning of the skin," which resembles the incipient stage of the diseases under consideration, and although we bannot expect a cure from Dulcamara, it may be well to administer it as an intercurrent or palliative remedy in a complaint which exhausts all the means in our arsenal to effect its expulsion; and often exhausts them in vain. Calntarides is also recommended by Rayer, who says he has found it more powerful than any other remedy, although in the doses usually prescribed its administration is attended with serious danger. Hepaar sulpiuris, we have been in the habit of prescribing in lepra, and have frequently seen unequivocal benefit derived from it, although in this as in most of the other medicines generally employed, there is no decided correspondence between its primitive symptoms and those of the disease. Pkosphorus produces symptoms more like some forms of lepra than any of the former medicines, and has been found an efficacious remedy in the disease. Among its symptoms are " round herpetic spots over the whole body, furfuraceous dry herpes (curative) scaling off of the epi SWillan, op. cit., p. 147. 404 'THE SKIN dermis." We must acknowledge that there remains yet much to be done before we can undertake the cure of this common and troublesome class of diseases, with that confident anticipation of success which we are enabled to entertain in reference to the treatment of complaints, which, from their nature and duration, ought to be as unmanageable as this one; and we must hope that if we vigorously prosecute the proving of medicines, we shall find some of more avail in the eradication of the scaly diseases than those we have now to rely on. The first of the papular eruptions is stroplulus, or red gown or gum,1 hardly deserves the name of a disease in its ordinary and simple form, occurring within the first two months of infant life. There is no other papular eruption unattended with fever with which this can be confounded, and its chief importance is derived from its frequent alliance with gastric or intestinal disorder. It is dangerous to employ the cold bath when there is much of this eruption over the body, as there is a risk of the transference of the irritation from the external cutaneous tissue to the internal mucous membrane. Rayer recommends a decoction of Althmea-root to be added to the warm water in which the infant is bathed. This addition is said to have a powerful effect in allaying the uneasy irritation and to be unattended by any bad consequences. Chamomilla is almost the only homoeopathic medicine which it is necessary to administer. Besides being well adapted to cure the slight disturbances of infant life geGum seems a corruption of gown. It was called red gown from its resemblance to a printed cotton, and the name is still retained in certain counties of England. AND ITS DISEASES. I405, nerally, some of the symptoms it produces present a marked resemblance to those of strophulus, viz.: "Red rash on cheeks.and forehead, without heat; small red spots on the skin, the spots being covered with rash pimples; thick clusters of red pimples on a red spot on the skin, itching, especially at night, and somewhat smarting, in the region of the lumbar vertebrm and the side of the abdomen. Rash of infants and nursing females." It is usual and probably advisable to give also a few doses of Sulphur either after the Chamomilla or in alternation with it. -Lichen is the sb'opiulus of adult life. Consisting of a red papular eruption, attended with more or less itching, terminating in a scurfy exfoliation of the cuticle, sometimes becoming pustular, and not unfrequently passing into a chronic form of scaly disease of the skin. It is always connected with some general disorder of the system, which generally shows itself by feverish symptoms, headache and nausea, a day or two before the outbreak of the cutaneous affection. Summer and autumn are the periods of the year it prefers, and how much is due to season is shown by the occurrence of the "prickly heat"-a form of lichen-in almost all Europeans on their first sojourn in a hot climate. While an unusually hot temperature is undoubtedly one of the predisposing causes of this troublesome malady, some internal irritation is as certainly one of the most frequent of the exciting causes. And it often appears as a vicarious morbid action relieving the internal organs, and therefore it is not safe to use measures for its repulsion. "CThis accident," says Willan,1 "'is constantly succeeded by a I Op. cit., p. 47. 406 THE SKIN violent disorder of the constitution. I have observed in one or two cases where it was produced from imprudent exposure to cold, that an acute disease ensued, with great quickness of the pulse, heat, thirst, pains of the bowels, frequent vomiting, headache, and delirium." Another exciting cause of this complaint is some mental emotion. A case is related by the same author1 of a little girl who had been some time subject to an attack of lichen, which would appear if she were scolded: and it is more frequently met with in persons of a nervous than in those of a lymphatic temperament. It seems also in some way connected with a gouty diathesis. The two indications for treatment are to subdue the irritation of the surface and to eradicate the internal cause. To fulfil the former cold applications, either of pure water or vinegar and water, are recommended; and in chronic cases, the vapour bath is said to be very useful, although it is not free of danger in the acute form of the complaint. There is no doubt that all affections of the skin attended with itching are relieved by inunction, and the best unctuous substance for the various forms of lichen is Glycerine. It keeps the surface moist, and is not so disagreeable as greasy applications. Of the specific remedies, those which present most correspondence in their symptoms to lichen are the following: Aconite-besides the feverish symptoms which often accompany lichen-produces " stinging, and feeling of soreness in various parts of the body; spots like fleabites, especially on the hands and face; large red and ' Op. cit., p. 258. AND ITS DISEASES. 407 itching pimples; reddish pimples filled with an acrid fluid." Ammoziuwr rnurialicum.-" Erratic itching and biting over the whole skin, in the evening mostly, before lying down; after lying down, the symptom passes off sometimes.; violent itching over the whole body, in the evening before lying down, especially on the chest and forearms, with little pimples after scratching; violent itching around the *hips, at night and early in the morning, also of the thighs, legs, and round the bend of the knee, with rash-pimples, fine rash over the whole body for two weeks." Bryonia.-" Eruption of rash on the arms, on the forepart of the chest, and above the knee, becoming red in the evening, itching and burning previous to his going to bed, but when in bed and getting warm, rash and itching disappear. Pimples make their appearance on abdomen and hips with a burning itching, when scratching the parts they feel sore; eruption on the whole body, especially on the back, extending to the upper side of the neck, itching so violently that -he would like to scratch the parts to pieces." calmnomilla produces this characteristic symptomn"thick clusters of red pimples on a red spot on the skin, itching, especially at night, and somewhat smarting-in the region of the lumbar vertebre and the side of the abdomen, occasionally a shuddering is felt all around, especially in the evening." Cocculus.-" Red miliary pimples on the face, back and chest, itching. in warmth." Coniiun.-" Fine, scarcely visible, eruption on the * 408 THE SKIN face, back, and remainder of the body, itching like a tingling creeping under the skin." Graphites.-" At night the whole body becomes covered with small pimples without sensation, they go off again in the morning; small red itching pimples, and with their tips full of pus, appear frequently on the skin, they burn when scratched, and disappear on the following day; spots like flea-bites on different parts of the body; a number of red itching spots on the whole body, especially the calves, for seven days." Mercurius produces-" Intolerable stinging itching as from flea-bites, in the evening; round stigmata (on the thighs and legs), gradually changing to round ulcerated spots, and becoming finally covered with a scurf; small itching pimples, afterwards changing to ulcers, during the healing of which the surrounding skin peels off." Natrum muriaticum presents some striking resemblances to lichen in the symptoms ascribed to it, viz.: "Red spots, the size of a pin's head, over the whole body, preceded by a feeling of heat in the face, on the abdomen, arms, and lower limbs, the spots itch, and when rubbing them the whole body becomes red for half an hour; small pimples on the abdomen and lower limbs; rash over the whole body, with stinging sensation in the skin; miliary eruption over the whole body, in the neck and throat, on the abdomen, nates and thighs, the eruption was at first felt only, afterwards it became visible in the shape of small millet-seed, scratching made it redder and harder, the itching prevented sleep." Phosphoric acid produces red, smooth pimples on the AND ITS DISEASES. 409 forearm and neck, with red areolze, feeling sore when touched; rash over the whole body, more burning than itching. To the homceopathic action of Sulphur in the cure of lichen Rayer bears the following important testimony: " Sulphureous baths so generally and indiscriminately recommended in the treatment of cutaneous affections are constantly hurtful in acute lichen, and very seldom serviceable in the chronic form of the disease. These baths may even cause a lichenous eruption; it is by no means an unfrequent circumstance to see lichen agrius appearing among individuals under treatment for scabies by means of sulphureous water bathing. Nevertheless I have obtained the cure of several cases of obstinate hereditary lichen, apt to return at frequent intervals, by effecting a material modification of the constitution by the use of artificial sulphureous water baths prolonged during several hours every day. Results of a similar description have been observed from the natural baths of Louesche and Schinznach."' Prurigo, resembling lichen in its general character, is distinguished from it by the papular eruption of which it consists being of the same colour as the surrounding skin, by the little brown spots of effused blood that besprinkle the affected parts, leaving evidence of the violent scratching with which the sufferer has attempted to relieve the intolerable itching from which the disease receives its name. The severity of the symptoms differ according to the period of life at which they appear, being milder in infancy, so that the term mitis is applied 1 Op. cit., p. 585. 410 THE SKIN to this variety; more severe in adult life, when the sensation is compared to the biting or crawling of countless ants below the surface of the skin, and hence called formicans; and most severe when it affects the aged, so that in the melancholy words of Willan " those who are affected with it in a high degree have little more comfort to expect during life, being incessantly tormented with a violent and inveterate itching." Besides being in its own nature a most intolerable irritation, it is sometimes accompanied by the production of numerous parasitic insects, which naturally increase the annoyance. The number of these is often incredible. In one case quoted by Willan, without any expression of distrust, two servants were employed in removing them in pailfuls from their master and throwing them into the sea. Distressing as the irritation is when it merely affects the external skin, still more dreadful are the consequences of the disease when it attacks the genital organs, especially the vulva and orifice of the vagina of the female. The following description of it, given by Professor Lorry, is so striking that we shall quote it entire: " Morbus ille adultos ut plurimum et primum pubertatis florem agressos adoritur, eosque qui, caste viventos, urgenti tamen impetu ad venerem ferrentur; mulieres etiam sed maturius adoritur. Ejus ortus primo metior est et pruritui totus continetur. At pruritui illi tum in maribus tum in feminis jungitur ardor in venerem inexplibilis. Mores et precepta repugnant, coercet virtus vivax, at manus indocilis ad has partes fertur, scalpendoque malum irritatur, et animus ipse in partem operis venit cum artuum tremore et palpitatione.

Ardor semper inest, et ad quemvis levissimum incessum exhalet humor olentissimus, fervente interea oestro vinereo."I Although in general this disease cannot be traced to derangement of any.internal organs, yet it seems sometimes to be of a vicarious nature, for there is an instance of sudden death from the repulsion of this eruption. Dr. Lettsom, who reports the case, says " another patient I Lorry de moirbis cutan., 4to, p. 449. 412 THE SKIN was relieved in the same manner (by the occurrence of prurigo) after having been much debilitated by frequent fits of the gout; he imprudently, however, endeavoured to allay the troublesome sensation of itching by a strong saturnine solution, and after using this application for a few days he suddenly expired in his chair."' For mitigating the irritation of prurigo, cold baths are generally employed, and the douche bath of cold water is said to be useful in prurigo pudendi. Instead of the plain water-douche the gelatino-sulphureous douche is strongly recommended by Rayer,2 and he relates a case which affords striking evidence of its efficacy. " A lady, aged 26 years, was attacked with the disease in February, 1823, on the upper and inner parts of the thighs near the greater labia, and upon these parts themselves were detected a number of distinct papille nearly of the same colour as the skin. During the day the parts affected were the seat of an incessant pruritus, which grew more severe in the course of the evening, completely interrupted sleep, and lasted through most of the night. A variety of severe measures were had recourse to but without any permanent benefit, and at the end of two months and a half, after consulting with Dupuytren, it was resolved to try the gelatino-sulphureous douche bath; after the first few days the application had a wonderful effect in allaying the irritation. The patient at once recovered her tranquillity and her sleep, and after using the remedy twenty-five times at the temperature of 250 R., for ten or fifteen minutes each time, she obtained a complete cure."

The vesicular diseases pempkigus and pemploly,are so nearly allied that no practical end is served by their separation. They are easily recognised by presenting the appearance of large blisters, which look exactly like the effects of a burn or scald. Pemphigus may be either acute or chronic, the former variety is much rarer than the latter. The affection seems to depend generally upon imperfect nutrition, giving rise to an enfeebled condition of the nervous system. Dr. Duchesne Duparc relates a case which occurred in the hospital of St. Louis, of a girl of eighteen years of age, who had never menstruated, and who had been affected with chronic pemphigus from the time she was five years old. It is said also sometimes to depend upon the presence of a specific poison. Mr. E. Wilson describes how a surgeon punctured himself when opening a thecal abscess, upon which accident the arm swelled as high as the armpit, and was three weeks in this condition: some three or four weeks after it got well a crop of pemphigus appeared on the leg, and had lasted with occasional intermissions for eighteen months. There are two important general directions given in regard to the treatment of this disease; the first is, that the patient should be allowed full diet, to impart vigour to the system, as deficiency of vital force seems to be one of the chief predisposing causes of the complaint; the other is that it is of great consequence to support the blisters, and thus to prevent the premature discharge of their contents, for they possess irritating properties, and 27 418 THE SKIN tend to aggravate and extend the disease if allowed to flow over the skin; besides, too early rupture of the cuticle exposes the raw skin beneath to the injurious effects of friction. Indeed it is better when the blisters do not burst at all, but dry up. Rayer strongly recommends the use of a perforated patch of rag, spread with simple ointment, to afford support to the margin of the vesicle where it is most likely to give way, and to diminish its elevation above the surrounding skin, so as to lessen the risk of the upper part being rubbed off by the unavoidable friction to which it must be exposed. The specific medicines suitable for the treatment of pemphigus are the following: Bellaclonna-" Watery vesicles (on the palm of the hand and tibia), so painful that he would like to scream." Causticiumn -" Large vesicles on the chest and back, with anguish in the chest (orthopnoea), and fever, consisting of chilliness, heat and sweat; large painful blisters on the left side of the chest and back, which burst; these symptoms are accompanied by great feverish heat, sweat, and anxiety." Phosphorus-" Painful hard blisters in various parts, not itching; blisters, bursting with moisture." Rh us toxicodendron-" Confluent vesicles, most of them containing a milky or watery fluid, with peeling off of the skin, in three days." This is the medicine most relied on in the cure of pemphigus, whether acute or chronic, and the result of our experience in the disease fully warrants the utmost confidence in the efficacy of the remedy. We suspect that it was from its observed power over pemphigoid eruptions that it was supposed useful in vesicular (so-called) erysipelas. The two affections, AND ITS DISEASES. 419 however, are essentially unlike, and the action of Rhus corresponds much more with the general symptoms which attend pemphygus than with those which attend erysipelas. ]Rupia differs from the vesicular diseases just described, in its contents becoming very rapidly of a sero-purulent character, and thus forming crusts thicker in the centre than at the circumference, so as to resemble an oystershell; which, when removed, leave behind a small illconditioned ulcer. It always occurs in persons of a weakened or depraved constitution of body. 4 In the treatment of this eruption, it is of importance to puncture the bullae of which it is composed, at an early period of their development, before the serum has been transformed into pus; this prevents the formation of the thick scab, and the confinement of the injurious matter upon the surface of the denuded skin. Besides allowing the escape of the contents of the vesicle, it is well to apply a light bandage or water dressing to the sores; and the diet should, be generous, or at least nourishing and abundant, as the disease is often the consequence of insufficient or pernicious food. Warm baths are also recommended. The medicines best suited to the treatment are the following: Arsenicum-" Black blisters, burning and very painful." Although there is nothing in this description very distinctive of rupia, yet there is enough, taken in connection with the general action of the medicine, to induce us to recommend it; particularly as in the few cases of the disease we have seen, it appeared to act beneficially. Kali bichromicumn-" In seven days vesicular eruption 420 THE SKIN on a red and elevated base (itching and burning much, especially when exposed to steam), in a few days becoming pustular, and presenting a dark point in the centre; invading hands, arms, face, back and belly. On the belly near the umbilicus, some spots, evidently of abraded vesicles, presenting a deep hollow appearance, which remains after they are healed." In a few days, an eruption of red round spots broke out on the back, arms and belly; the spots then formed pustules the size of a pea, covered with a scab, which came off in a few days, and left a small dry ulcer, which partly healed up in about a fortnight, leaving a colourless depressed cicatrix." These symptoms were produced by the local action of the salt; but taken in connection with the other symptoms of this medicine, we believe it may be useful in some forms of Rupia. Mliercurius -" Herpetic spots and suppurating pustules, which either run into one another, forming at times dry and scaly spots, at times discharging an acrid humour, or which remain sore, become hollow, and afterwards raised and cicatrised; new pustules springing up in the neighbourhood." This is marked as a curative effect of mercury, not a pathogenetic. Plumbe in his treatise on skin-diseases, however, describes a case of rupia in which the administration of Murcury was at first attended with manifest aggravation of the disease. Rhus toxicodendron--" Black pustules with inflammation and itching, rapidly spreading over the body." These so-called "black pustules" are probably vesicles filled with serum, deeply tinged with the colouring matter of the blood, and therefore resembling rupia, which may be called an intense vesicle. AND ITS DISEASES. 4,21 Secale cornutumn.-" Bloody blisters on the extremities, becoming gangrenous." This medicine presents considerable resemblance in its action with the symptoms of rupia escharotica, described by Dr. Whitby Stokes. This author mentions that the popular remedy for the disease was scroplularia nodosa, and from personal experience recommends its administration in the form of a decoction. Herpes admits of a good practical division into herpes phlyctenoides, and herpes circinatus; the former is distinguished by the irregular distribution of the vesicles of which it consists; the latter by the regularity of the form the eruption assumes. The phlyctenoid variety affects various parts of the body, especially the lips, where it gets the name of labialis, and the prepuce (preputialis). The little blisters run their course in about eight days, and then dry up and form scabs. The disease is of a purely local origin for the most part, and attended with little or no general constitutional disturbance. Of the circinate herpes, the most important, both in point of frequency and severity, is zona. This remarkable affection of the skin is recognised by its forming a red semicircular belt of variable breadth round the body, on which pearly white vesicular elevations are disseminated. This disease, unlike the phlyctenoid, is essentially connected with some derangement expressing itself generally through the nervous system. When treating of its pathology we mentioned Simon's opinion, that it depended upon an affection of the nerves; and this is corroborated by the following case, which occurred to Recamier: "Two females were attacked with sciatic 422 THE SKIN neuralgia; groups of vesicles, resembling those of herpes zoster appeared here and there upon the thighs and legs of the affected sides; but instead of increasing in size, attaining maturity, in a word, of running the usual course of zona, they became flaccid almost immediately after being thrown out, and soon dried up; so that after the fourth or fifth day, no further traces of the eruption were visible."' In fact, zona is sometimes little more than a symptom of neuralgia; as the neuralgic affection precedes the eruption by some days, and frequently remains long after this has disappeared. Besides its connection with neuralgia, it is said to be indicative of predisposition to disease of the part over which it is situated; and Mr. E. Wilson has recorded the following interesting case: "As an illustration of the occurrence of this affection in a symptomatic form, I have preserved the notes of a case of partial herpes zoster, in which the eruption appeared upon the left shoulder, over the infra-spinata fossa, in a young lady sixteen years of age, in the spring of 1840. Upon examining her chest I found it to be small and contracted, and her respiration weakly, but she had no cough; I explained to her mother that the eruption was of little consequence, otherwise than an indication of susceptible lungs; that she must use the greatest precaution in protecting her from the influence of cold; and I gave her such hygienic instructions as I deemed best for the purpose of carrying out that object, ordering the frequent application of a counter-irritant to the chest and trunk, and the use of flannels nest the skin. I heard no more of this S' Revue MiNedic.,' t. xxv, p. 435, quoted by Rayer, p. 258. AND ITS DISEASES. 423 young lady till the January following, when I visited her on her death bed, at her particular request. She had fallen a victim to phthisis, and died a few days after my visit."' Of course the connection between the fatal disease and the previous eruption may have been entirely accidental, but whether it is so or not, can only be proved by the careful collection of similar cases. Herpes zoster and herpes circinatus, in which the group of vesicles assume a circular form, are seldom or never chronic, and generally terminate favorably within three weeks. In old people, however, there is considerable danger of gangrene of the subjacent integument, which has sometimes proved fatal. In the treatment of herpes labialis it is advisable to prevent the formation of the disfiguring scabs which form the natural reliques of the vesicles by puncturing them with a needle. The following medicines are the most suitable for the cure of this complaint: Arsenicumn -" Red herpetic skin round the mouth; eruption along the margin of the vermilion border." Belladonna -" Small pimples on the lips, covered with a scurf, and smarting as if they had been touched by saltish water; pimple on the upper lip, tingling when not touched, contact excites a stinging itching in it."

Dudcamara -" Pimples and little ulcers round the mouth, with tearing pains when moving the parts." Graphites-" Eruption near the corner of the mouth: eruptions on the lip; small white blotches on the upper lip; thick-set, whitish pimples on a red base, and somewhat itching, near both corners of the mouth under the lips; a vesicle on the upper lip, with cutting pain." Ilepar sulp/iuris -" Eruption in the corner of the mouth, with a sensation of heat in that part; red itching spot below the lower lip, which was soon covered with a number of yellowish vesicles, forming a scurf." MLercurius-" Yellow crusts on the upper lip near the margin, with smarting and burning pain." Silica-" Eruption on the lips, vesicles on the margin of the upper lip, stinging, when touched causing a smarting pain; pimple on the margin of the vermilion border of the upper lip, first itching, afterwards, when converted into a scab, merely smarting." In herpes preputialis the following medicines may be administered: Aurum--" Itching of the scrotum." Dzdcamara-" Heat and itching of the genital organs; herpetic eruption on the labia majora." Hlepar sulphuris-" Itching of the penis, and the frenulum preputiale; itching of the glans; humid soreness in the fold between the thigh and the scrotum, with smarting pain, as if the parts were excoriated; itching of the scrotum."

Sulphur-r-" Troublesome itching of the pudendum, with pimples all round; painless vesicles on the outer parts -of the pudendum." To Aerpes phlyctenoides, not confined to any special locality, such as the lips or genital organs, but spread indiscriminately over various parts of the surface, the following medicines are the most suitable: 426 THE SKIN dconitum -" Large red and itching pimples; reddish pimples filled with an acrid fluid; isolated pimples of the size of a pin's head, and filled with a serous fluid, make their appearance on various parts of the skin, especially on the forehead, nape of the neck, and on the face, after a while the pimples dry up and peel off; vesicular eruption on both temples."

Nor do we believe that the severe neuralgic pain, which so frequently follows this affection when treated according to the old system, which is in fact negative treatment, will often occur in cases treated by rhus from the beginning of the attack. We lately had a patient under our charge who exhibited all the premonitory symptoms of zona, which were entirely relieved in about a week by the use of this medicine. When Rhus is not sufficient to accomplish the cure, and when there is much burning, insupportable pain, graphites is of great value, mercurius is recommended if there is much itching and a great tendency to suppuration, and pulsatilla after or alternately with mercurius when there is severe lancinating pain.' If there remain neuralgic pains after the disappearance of the eruption zincum metallicum may be administered, but if the cure is not speedily effected it will be found a most troublesome affection, requiring much patience both on the part of the sufferer and the physician, and requiring the latter to put forth all his skill often without ultimate success. Eczema in its simplest form consists of an eruption of small vesicles, generally flat and not so globular as those of herpes, spread over a greater or less extent of the sur. face; they are filled with limpid serum which exudes when they are mature, and after exfoliation of the cuticle the whole affection terminates. When the inflammatory I Jahr, 'Du Traitement Homoeopathique des Maladies de la Peau.' AND ITS DISEASES. 429 action on which this vesication of the skin depends is more severe, the surrounding parts are red, and this variety is called eczema rubrum. When th3 serum of the vesicles becomes converted into a bloody and semi-purulent fluid, and the vesicles themselves break down and unite, then it is called eczema impetigenoides. Besides these varieties depending on the nature of the eruption, the disease has received different names from the seat of its occupation; of these the most practically important are capitis, faciei, auriculare and perineale. Instead of being acute in its course it may be chronic, and so called chronicum. That it is often caused by some purely local irritation is shown by the fact of it so frequently appearing on the hands of grocers, from handling sugar and other dry and hard powders, as to have got the name of grocer's-itch; it is also very common among bricklayers, and Bateman met with a very bad case in a file-maker, occasioned by the particles of metal producing a constant irritation of the skin on the hands. Besides these local causes, it sometimes originates in constitutional disturbance, and when this is the case its effects are salutary. It was observed by M. Billard, at the Foundling Hospital at Paris, that infants who were affected with eczema capitis generally thrive remarkably well, and Rayer speaks of their exemption from convulsions and diarrhoeas of dentition. This form of the disease is most frequent among fair-haired and scrofulous children, while, on the other hand, according to Rayer, consumptive persons are rarely affected by eczema in any of its forms. From the vicarious relation it holds with various internal morbid actions, its sudden disappearance, either by na 430 THE SKIN tural effort of the constitution or by the use of local remedies, is considered highly dangerous. Alibert mentions a case of insanity produced by its retrocession, and Rayer had a patient who had long suffered from eczema of the fundament, and was attacked with a violent and long-continued inflammation of the mucous membrane of the intestines and pulmonary organs, which occurred with the disappearance of his chronic eruption, lasted all the time of its absence, and went off as soon as it was re-established in its old position. Rayer makes the general observation, that in childhood eczema is more prone to affect the head and face and upper part of the body, in middle age the trunk, and in old age the lower extremities and fundament. The milder forms of this disease are not dangerous, and are speedily cured; but when chronic it is an obstinate and difficult complaint to manage, and in the aged, unless very troublesome, it is better to let it alone, as its cure is attended with danger to their life. Its worst form is that which affects the perinaeum and scrotum in the male, and the vulva of the female, from the excessive itching and irritation it produces, which, bad as they are in any part of the body, become worse from the difficulty of obtaining relief, and from the erotic excitement produced by the endeavour, a source of dreadful present suffering, and not unfrequently inducing practices destructive both of the physical and moral well-being of the sufferer. For the treatment of eczema simplex and rubruzm, the following medicines are suitable: Aconitumc-" Vesicular eruption on both temples." Conium -" White transparent pimples, filled with an acrid humour, which form scabs resembling those AND ITS DISEASES. 431 of the itch, accompanied by local, fetid, smarting sweat." ]ulcamara-" Violent itching eruption of red spots, with vesicles; eruption of white blotches, with red areolee, stinging, itching and burning when rubbed, on arms and thighs." Mercurius produces an affection of the skin so like natural eczema as to have got the name of eczema mercuriale. It is thus described by Mr. E. Wilson:-" Eczema mercuriale is characterised by a red efflorescence, occurring in patches of variable size, and surmounted by transparent vesicles of extreme minuteness. In the mild form of the eruption the vesicles are not perceived until the surface is examined with care, but in the more severe degrees the vesicles increase in size, and their transparent contents become opaque and purulent. In some instances, particularly when febrile symptoms are present, the efflorescence occupies a large extent of surface, sometimes the entire body, and assumes the appearance of rubeola; at a later period the small semilunar spots coalesce, and form patches of larger size. The more usual seat of the eruption is the trunk of the body, or the thin skin of the pudendal region; sometimes it appears first on the backs of the hands, and more rarely on the face. The eruption is preceded by heat and smarting of the skin, and its progress is remarkable for excessive heat, with smarting and pruritus. When the vesicles are very minute they dry up without giving rise to secondary inconvenience; but when they occur in folds of the skin, or are larger in size, they are usually broken, and the abraded derma pours out an acrid and offensive ichor in considerable quantity." 432 THE SKIN Among the symptoms in the proving the following correspond to those of eczema: " Eruption on both thighs in the evening (preceded by heat in the head and dorsum of the foot), itching; a burning water oozing out after scratching, as when one pours brandy into a wound. Itch-like eruption on abdomen and thighs, with itching; eruption resembling greasy itch on the lower limbs, sexual organs, bends of the knees, neck and abdomen considerably raised, red as if sore, humid and itching." There is no medicine to compare with mercury in the treatment of this disease. I generally give it in the form of ointment, as well as internally. Oleander I have known of great use in chronic eczema of the lower part of the body; this too was given as an ointment. Phoslgphorus -" Painful hard blisters in various parts, not itching; blisters bursting with moisture; itching vesicles between the fingers and in the bend of the knee." Rus ltoxicodendron -" Small burning vesicles, with redness of the skin of the whole body, except on the hairy scalp, the palms of the hands, and the soles of the feet; burning, itching eruptions, particularly on the scrotum, prepuce, eyelids and eyes, (arms and loins,) with swelling of the parts, and small yellowish vesicles which run into each other and become moist, the larger ones terminating in suppuration with red areolae, the smaller ones drying up more rapidly, and scaling off in a few days; confluent vesicles, most of them containing a milky or watery fluid, with peeling off of the skin in three days."' AND ITS DISEASES. 435 to consider idrosis along with it. Idrosis, or sweating disease, may affect the body either partially or entirely, and may be sporadic or epidemic. When confined to one part of the body it most commonly affects the feet, and may continue for years; in these instances, the perspiration, besides being excessive in quantity, is usually of a fetid smell, and attended with sharp stings of pain in the heel. Its sudden cessation is often followed by dangerous internal disease of the bowels or respiratory organs. General idrosis, whether contagious or epidemic, or sporadic, seems to depend upon the temperature and electric condition of the atmosphere, as it generally occurs when there is an unusual amount of heat and moisture in the air, and the localities in France, where it has been most frequent, present these conditions in a high degree. The most celebrated epidemics of this disease have occurred in this country, and hence it has acquired the name of sudor Anglicus. It seems to have been more rapidly fatal than even cholera, and it naturally produces the utmost terror during its devastation. The following extract from the account given by Dr. John Kaye or Caius, presents so striking a picture of the disease, that although somewhat out of place we venture to insert it here:- Quosdam enim in via cum iter facerent sistulit; quosdam domi ostia et fenestras reserando interemit; quosdam per lusum atque jocus parum joculariter jugulavit; per jejunia quosdam; quosdam per saturitatem abripuit; in somno aliquos, nonnullos vigiles interfecit, usque adeo ut ex multis ejusdem familime paucae a febre incolumes perstiterint; ex pausis nulli plerumque, intacti evaserint. Ex his alios brevi momento, alios unius, duarum aut trium, alios 436 THE SKIN quatuor aut eo amplius horarum spatio post quam sudare coeperant de vita sustulet. Sepissime qui in prandio hilares erant sub coenam mortui fuerunt. * * * * Itaque ex talibus initiis in dies ingravescentibus ubi acerbiora incrementa longius latiusque se fundente malo subsecuta sunt, vix credas quis pavor, quantus metus omnes Britannos invasit; presertim cum ejus conditionis miseranda quae tur urgebat, contemplatio funestaque mortis imago nullis spem vitse (cujus usura omnibus solet esse carissima) non ademeret. Neque enim morbo ulla clementia fuit nec ullum miseris mortalibus securum refugium. Etenim nusquam non populabatur nusquam non seviebat malum."' We cannot help suspecting that the statement continually repeated in treatises upon homoeopathy about this disease having been cured by sudorifics, rests upon insufficient evidence, or at least is of more limited application than the way in which it is generally made conveys to the reader's mind. It is of great consequence in the treatment or prevention of idrosis to maintain a cool temperature by proper ventilation of the apartment and light clothing, and the neglect of these obvious measures was the cause of the great frequency of the complaint in former times. The following medicines are those best indicated and most frequently successful: Aconitum--" Peculiar sensation over the whole body, as when the vapour is suddenly descending upon the skin in a vapour-bath, and drops are felt upon the skin; constant sweat, especially in the covered parts." In a case of idiopathic general idrosis which had affected a S' Joannis Caii Britanni de Ephemera Brit.,' 1721.

The white Agaric is recommended in the profuse sweat of phthisis.2 Antimonium crudum--" General sweat, without smell, which made the tips of the fingers soft and wrinkled; sweat during sleep; early in the morning when waking a gentle sweat covers the whole body; general warm sweat in bed every morning; sweat returning at the same hour for three days in succession."

Belladonna-" Sweat during or after the heat, from the least movement, over the whole body, especially on the face and on the nose; cold sweat on the forehead; sudden evanescent sweat; sweat having an empyreumatic smell, imparting a dark tinge to the linen: sweat every night, during the sleep, or only in the daytime; morning sweats; sweats with enuresis." 1 Dupont, -Iist. d'une sueur chronique, &c., ' Journal G6n. de M6d.,' 1807, t. xxx, p. 33. 2 Bisson, 'De l'emploi de l'agaric blanc contre les sueurs dans la Phthisie pulmonaire,' Paris, 1832, quoted by Rayer, p. 920. 438 THE SKIN Bryonia-" Sweat breaking out readily after making the least exertion, even during a walk in the cold air; sweat during a meal; profuse sweat, particularly in the morning or at night; oily sweat day and night; warm sweat in the palms of the hands, or also over the whole body, even about the head; cold sweat on the forehead and head; sour sweat at night, also preceded by thirst, oppressive drawing in the head, when the sweat is about to terminate, and succeeded by a muddled condition of the head. Vaporous exhalation from the skin from evening until morning, or from 3 o'clock in the morning, with lying on the back, light slumber, and dryness of the mouth." Rayer, describing the epidemic malaria which raged in the department of Oise in 1821, says: " Many individuals who have gone to bed well, awoke labouring under the disease, their bodies bathed in sweat, which never disappeared till their death or convalescence. Occasionally an almost imperceptible degree of fever, a burning heat, or a feeling as if a vapour were passing over the limbs, and still more frequently a sense of constriction about the epigastric region precedes by some hours, or by some minutes or seconds only, the appearance of the sweat or rather the hot vapour, which, steaming from a few places at first, is soon exhaled from the entire surface."'

The next vesicular eruption we come to is scabies, or itch. It is of great consequence to be quite sure of the diagnosis of this disagreeable disease. The only unequivocal symptom is the detection of the acarus, which if present is always to be found at the extremity of the hole it has burrowed under the skin, or if absent, the furrows it has left may be easily recognised by a magnifying glass. Besides, the vesicles of itch are sharply pointed cones, while those of eczema are round at their summits and there is a peculiar scaliness of the surrounding skin. The itching sensation is of rather a pleasant kind, not sharp and burning like that of prurigo and eczema, and the gratification of scratching is so great that James the Sixth is reported to have said, it was a pleasure fit only for kings. This, however, may have been a witty libel upon his native land. As there is no sort of doubt that the insect propagates the disease, however else it may arise, it is manifest that th6 primary indication of cure is to kill this parasite, and any unctuous substance applied abundantly to its habitation in the skin is sufficient to effect this object. The plan we 442 THE SKIN generally adopt, is to order the patient to rub the affected part with simple lard, and at the same time we give two drops of the mother tincture of Sulphur three times a day. Jahr recommends washing the surface with diluted Sulphuric Acid, and administering the 300th or 400th dilution of Sulphur internally. Whether these very high dilutions are ever superior to lower ones may be a question, but we can hardly imagine that any one who has had much experience in the treatment of itch, unless misled and blinded by a theory, could seriously advise their use in that disease in preference to the lowest. Besides Sulphur various other remedies have been employed apparently with success. M. Bazin, who has had large opportunities of observation at the Hospital of St. Louis, at Paris, recommends an ointment of lard and Chamomile flowers, prepared by heating equal parts of those two with one of olive oil in a sand-bath and using it by inunction. The advantages he ascribes to it, are the instant relief it affords to the itching and the absence of all secondary eruptions which frequently follow the use of Sulphur ointment. We should think the plan well worth a trial. In the Allgem. Hor. Zeitung, for May, 1849,.Dr. Bosch recommends, from personal experience, the use of Peruvian balsam for this disease. He says he has found it effectual in cases which had baffled the ordinary curative processes. He gives night and morning two drops of the first dilution of the Balsamum Peruvianum nigrum, and rubs the balsam into all parts affected with the disease night and morning. Varicella or chicken-pox consists of an eruption of small red slightly raised spots, on which vesicles appear 444 THE SKIN invasion, occupying three or four days, is characterised by the ordinary symptoms of fever, attended with pain in the loins, the origin of which Chomel refers to the kidneys and believes to be pathognomonic; and Heberden remarks, that its intensity corresponds to the severity of the subsequent course of the disease. The eruption consists of small red elevated conical points disseminated more or less thickly over the surface, especially on the face and lips, and these papular elevations are gradually transformed into umbilicated vesicles surrounded by a red areola. This transformation is completed by the fourth or fifth day. On the sixth day the lymph of the vesicles is converted into pus, giving a yellow colour to the eruption, which now loses its central depression and assumes a flattened spheroidal shape. The process requires two days for its completion, and terminates in the bursting of the pustule, the discharge of its contents, and the establishment of the secondary fever. After this, the desiccation begins, all the parts where the eruption existed are covered with a thick scab, consisting of indurated pus and epidermis, which comes off about the fourteenth day, and leaves the skin red and frequently marked with fissures and pits. When smallpox prevails, we are frequently asked by our patients whether it is advisable to be re-vaccinated, and it is well to have some positive data to rest our opinion upon. Some years ago this operation was performed upon the Prussian army: 42,000 of them had been previously vaccinated; of these, 33,000 had distinct marks, in 5645 it was indistinct, and 2577 had none at all; when all were re-vaccinated, in 19,117 it ran its ordinary course, in 14,000 it produced no effect, AND ITS DISEASES. 445 and in 8672 it was irregular.1 When smallpox raged in this army, the only fatal cases, seven in number, which occurred, were among those who had not been re-vaccinated, in all of whom it was very mild. These facts are enough to make us concur with the managers of the vaccine establishment at Vienna, who recommend that when " smallpox rages, it is well to re-vaccinate all who are exposed to the infection." 2 In the treatment of smallpox, it is most important to prevent the pustule from bursting, if that be possible,"for there is more danger in this disease from the result of the local mischief, than the constitutional derangement. Of the plans most in vogue, perhaps the best is the old Arabian one, of puncturing the matured pustule with the point of a lancet, and gently pressing out its contents, which may be removed by a wet sponge. It is maintained that the exclusion of light prevents the mischievous suppuration; and Dr. Picton, of New Orleans, states that no instance of pitting after smallpox occurred in his practice, to patients who had been kept in the dark.3 The subject was investigated experimentally by M. Serres, who had found unusual success attend the treatment of patients kept in a dark ill-ventilated cellar, at the time La Pitie Hospital was too full to hold them; he covered some pustules with capsules of glass, so as to exclude both light and air, and the result was, that they shrivelled and dried up. It seems advisable, then, that 1 Kleinert's ' Repertorium,' 1840. 2 'Die Anomalien der Schutzpocken,' von M. Viszanik und A. F. Zohner. 3 American Journal of Medical Science,' quoted by Wilson. 446 THE SKIN the apartment should be kept as dark as possible: this cannot be attended with any serious evil, and may be productive of important benefit. The following medicines are suitable for the treatment of smallpox. Aconitum--" In the eruptive stage of smallpox." Arsenicum--" Should be exhibited in smallpox, when hoarseness, angina faucium, and diarrhoea supervene." Mercurius-" A few days after rubbing himself with mercurial ointment, the patient experiences a troublesome itching at the place where the ointment had been applied; gradually the skin becomes rose-coloured; this redness is traversed by a few red streaks, which on inspection, prove to be the sound skin; the redness arises from an assemblage of larger or smaller spots; the reddened cutaneous surface imparts a sensation of burning heat to the finger; the redness disappears when pressing on it, but returns immediately after the pressure ceases the patient's general health remains perfect, the secretions are uninterrupted, and the pulse is not affected. Ten or twelve hours after, slight elevations are discovered by the finger on the reddened cutaneous surface, and on looking at it through the microscope, these elevations prove to be vesicles crowded together. On the second day the vesicles become more elevated, and are perceptible to the naked eye on looking at them obliquely; they are filled with a yellowish lymph; the itching abates somewhat immediately after the appearance of the vesicles. On the third day the vesicles become depressed, on the fourth day they desiccate, on the fifth the skin scales off. If the mercurial friction be continued, or if some other dyscrasia be lurking in the system, the above AND ITS DISEASES. 447 mentioned phenomena become more violent; the skin assumes a dark red tinge, the vesicles increase to the size of pustules, and the patient is attacked with feverish chills which 'he experiences even before the vesicles make their appearance; the eyes are slightly reddened, watery, the nose is stopped, mouth and pharynx are dry, the stool is retained, the urine scanty, red, the pulse rather hard, quick, and almost small."' So much for the effects of mercury in producing an affection similar to smallpox. Mr. E. Wilson makes the following statements:1 " Mercury administered internally, has long been known to possess remarkable powers in modifying the influence of variola upon the system, but it was left to modern times to prove that this agent has also the property of neutralizing the variolus virus when applied externally." After mentioning that M. Serres and M. Briquet made use of a plaster consisting of 95 parts of Mercury, 312 of common plaster, and 16 of wax of resin and of turpentine, besides a slight addition of balsamus, he goes on to say, "in the first experiment, a strip of this plaster was placed on the arm of a patient attacked with variola, while a similar strip of diachylon plaster was applied to the opposite arm; under the mercurial plaster, the development of the eruption was arrested; under the other plaster, no modification took place." In the second case the face of the patient was " covered with the plaster, a part of -which he tore off during the night which followed its application; the denuded surface was the seat of suppurating pustules, whilst on that portion which continued subjacent to the plaster, their abortion was effected." SOp. cit., p. 97. 4,48 THE SKIN In a third case-a man affected with "violent confluent variola, the pimples were small, scarcely raised above the level of the epiderma, and surrounded with a brilliant red areola, the vigo plaster was applied, and allowed to remain seven days; on its removal, it was found that no suppuration had been established, with the exception of four pustules, and these were situated near the mouth, and had not been in contact with the plaster; this patient was radically and rapidly cured, and no scars were manifested." Dr. Oliffe recommends that "the whole face should be covered with a mask of the vigo plaster, merely leaving a space for the mouth, nostrils, and eyes, and a little mercurial ointment should be applied to the eyelids. The plaster is allowed to remain for three days in simple smallpox, and four in confluent." Instead of this plaster, mercurial ointment consisting of an ounce of Ungt. hydr. fort. mixed with a drachm of starch-powder, has been successfully employed by Dr. H. Bennet of Edinburgh. Of course, the use either of the ointment or the plaster, should not supersede the internal administration of Mercurius. It seems that unless the Mercury be applied before the pustular stage of the eruption, it does no good; it should be used upon the second or third day of the eruption. " It exercises," according to M. Briquet, " a specific action on the cause, whatever that may be, which produces the variolous pustule, or acts as an antiphlogistic, &c." The immense importance of the subject seemed to require the production of the evidence in favour of the utility of Mercury in the treatment of smallpox, instead of giving merely the reported result of the plan; and we shall follow the same course in respect to the only AND ITS DISEASES. 449 other remedy which seems to us to have established its claims to confidence, we mean Varioline. In a paper which first appeared in the Horn. Vierteljahrschrift, Surgeon Schnappauf, of Dresden, relates his experience with smallpox matter. In a case of natural smallpox, he says: " opening a group of pustules, on one of the extremities, I succeeded in obtaining a clear watery lymph, which I drew off and mixed in a glass of aqua distil, pretty nearly in the proportion of the first dilution; after it was well shaken together, I added some drops of alcohol to prevent it becoming putrid; of this preparation I administered two drops every two hours on sugar of milk-the effects were quite wonderful, in so much that after the third dose, the greatest part of the painful and unendurable symptoms were abated, and the patient fell into a tranquil sleep, which lasted several hours. The most surprising effect, however, was the appearance of the pocks themselves, on the parts which were least exposed to the air, and where, as is always the case; the pocks had come out later than on the trunk and lower extremities; the pocks, instead of having increased ini size, were fallen in and shrunken like withered fruit; those that were still in the stage of lymph, did not go on to suppuration at all, but dried up very soon. The remaining symptoms, such as the stretching and burning pain of the skin, the swelling and fever, abated so rapidly, that the patient was relieved of most of her distressing symptoms in about sixteen hours.". " I have treated," he says, a little further on, " upwards of twenty cases, of every age, both of natural smallpox and varioloid, with Varioline, and in no one instance have I found it to fail in producing its quick and remarkable 29 450 THE SKIN effects." Dr. Trinks, of Dresden, says: "I can confirm the facts related in these observations of Surgeon Schhappauf. In the winter of 1848-9, there raged here the most wide-spread epidemic of smallpox which I ever remember; people of all ages and both sexes died of it; it seized vaccinated and unvaccinated alike with the same intensity; 4he eruption was preceded by violent affections of the brain and spinal marrow, which disappeared when it came out. Belladonna and Bryonia were of great service in that stage; in the septic state which frequently followed on that, Arsenic wag, as usual, of much benefit; against the salivation, Opium was administered with great success; Magn. had no effect whatever; nor Tart. Stib., nor indeed any homoeopathic remedy. On the other hand, the varioline exercised an alterative, shortening and curative power on the exanthema itself--a fact which must forcibly urge us to further trials of it." The difficulty of procuring this remedy fresh, unless smallpox be epidemic, may be a hinderance to its practical usefulness; for there is good reason to believe, from the experiments of Von Wenzel and others, that the virus on which its power depends, is easily destroyed by many chemical agents, as well as by spontaneous decomposition. Imnpetigo is recognised by its consisting of a number of small elevations of the skin, which terminate in a pustular apex. On the rupture of the pustule the contents are effused and concrete into a honeycomb mass; sometimes conical and depending like stalactitic formations. The eruption may be either disseminated irregularly over the surface (sparsa)-most frequently upon the trunk, legs, and feet, or it may assume a circular or AND ITS DISEASES. 451 other regular form (figurata), when it usually affects the face, particularly the cheek and upper lip. One of the most common seats of the disease is the scalp (iTpetigo capitis); here it is known as crusta lactea, as it usually affects infants at the breast. In the acute form the crusts produced by the indurated muco-purulent secretion dry up and drop off, and so the disease terminates. In the chronic form, however, no sooner is one crop of pustules thus converted into exfoliating scabs than another crop springs up to take the place of those which preceded them, and discharges its contents among the spongy scales. When this happens on the scalp the mass gets matted together with the hairs, the secretion corrupting from its confinement becomes more and more offensive, and the loathsomeness of the disease is aggravated by the swarms of lice which breed and lodge in this congenial filth. The want of cleanliness being one of the most common causes of this affection, simple and abundant ablution is sometimes a sufficient remedy. After the crusts are formed, the vapour douche is strongly recommended as the most effectual appliance for their removal, and it affords a wholesome stimulation to the skin. Of course, at an earlier period the use of hot baths or vapour is not desirable. The hair should be cut' out with a pair of curved blunt-pointed scissors, rather than shaved, this is equally effectual and less aitnoying, and if ample washing be not sufficient to remove the crusts, a poultice may be applied. If after thoroughly cleansing the head the crusts still continue to be reproduced, and the health of the child is either unimpaired or even improved, it is better to avoid all medication directed to the local grievance, for the chances are that 452 TIE SKIN the eruption is a salutary effort of the constitution which, if checked, would take some dangerous form. Among the following medicines the appropriate one for the cure of any special case will probably be found. Arsenicum--" Pustular eruption on the head, the temples, and between the eyebrows, causing painful itching, as if from a sore; eruptions principally about the lips and nose; pustules on various parts of the body, which cause burning pain and great anxiety." Calcarea carbonica-" Eruption on the hairy scalp, with glandular swellings at the neck." Such swellings frequently attend inmetigo capitis. " Thin moist porrigo on the hairy scalp." We have great confidence in Calcarea in the treatment of this disease when it affects the heads of scrofulous children. Cicuta virosa-" Extensive (suppurating) eruptions on the hairy scalp; suppurating eruptions (in the face), with yellow scurfs and burning pain." Clematis erecta-" Scaly herpes, with yellowish corrosive ichor." Graphites-" Humid eruption at the top of the head; it is painful to the touch; small pustules on the chin and chest." Hepar sulphuris-" Humid scald head." Kali bichromicum-" During the first week a profuse yellow scabby eruption formed over the upper lip." Mercurius-" Humid eruption on the hairy scalp, eating away the hair, with painful pressure, especially at the sore places; pustules on the upper and lower limbs, the tips of which are filled with pus, and itching; impetiginous herpes on the abdomen, thighs and knees." AND ITS DISEASES. 453 Nitric acid-" Scurfy, humid, itchy eruption on the hairy scalp." Rayer says: "I have treated very obstinate impetigos successfully by the Nitric acid, in doses of half a drachm daily in a pint of barley-water sweetened to the taste. It very seldom happens that this medicine is continued for a month or six weeks without accomplishing a cure." B]uzs toxicodendron-" Burning, itching eruptions, particularly on the scrotum, prepuce, eyelids and eyes, (arms and loins), with swelling of the parts, and small yellowish vesicles which run into each other and become moist, the larger ones terminating in suppuration, with red areolae, the smaller ones drying up more rapidly and scaling off in a few days." This is another medicine in which we have great confidence in the treatment of impetigo capitis, especially when the discharge is copious. Sepia-" Small itching pustules on the occiput, towards the nape of the neck, forming into ulcers the size of an inch, with rough crusts, under which the secretion continued for a long time." Silicea-" Itching, humid porrigo." Stapkisagria-" A number of itchy scabs on the hairy scalp; humid scabs, also with bad smell." Sulphur-" T'inea capitis, dry or fetid and humid, with thick pus, yellow crust and itching; crusta lactea," Viola tricolor is usually recommended in this complaint, but there is nothing in the proving to warrant its administration, and we do not know on what authority its reputation rests, beyond Jahr's italics, which arc certainly somewhat capriciously employed. 454 THE SKIN Ectyma is easily recognised from inmpetigo and other pustular eruptions by the large size of the pustules of which it consists; they are frequently as big as a split pea; sometimes there is so much induration of the surrounding skin that they resemble small boils, and leave an ulcer behind them, after they disappear with the rupture of the pustule and escape of its contents. It is rarely an acute, generally a chronic disease, and its favorite situation is the upper part of the trunk of the body, which it sometimes encircles. It almost never affects the scalp. The following medicines seem to correspond best to the symptoms it presents: Arsenicum-" Pulse 110; white pustules, some isolated, the greater part confluent, appear on the forehead, round the eyes, the cheeks, the arms, and shoulders, and upper part of the chest; they terminate in thick crusts, and leave well-marked cicatrices." Kali bichromicum-" In a few days an eruption of red, round spots broke out on the back, arms and belly; the spots then formed pustules the size of a pea, covered with a scab, which came off in a few days, and left a small dry ulcer, which mostly healed up in about a fortnight, leaving a colourless depressed cicatrix." iMercurius-" Visibly spreading herpes, afterwards several ulcers discharging a corrosive ichor; herpetic spots and suppurating pustules, which either run into one another, forming at times dry and scaly spots, at times discharging an acrid humour, or which remain sore, become hollow, and afterwards raised and cicatrized; new pustules springing up in the neighbourhood." AND ITS DISEASES. 455 R/ius-" Black pustules, with inflammation and itching, rapidly spreading over the whole body." Tartarus stibiatus--" Large, round, full, burning pustules, with red areolae, forming in two days and leaving deep cicatrices; furunculous, pustulous eruption, -occasioning a violent, painful itching, generally suppurating from the size of a pin's head to that of a pea; pustulous eruption, the pustules filling with pus, drying up in a few days, and sometimes leaving deeply penetrating malignant ulcers." Prumnculus-boils-is so familiar a complaint, and so perfectly recognised even by popular observation, that there is no need of saying anything about its diagnosis, and -we may pass at once to the enumeration of the specific medicines likely to be useful in its treatment. Arnica-'' Itdhing pimple between the thumb and the index finger, as if a splinter were lodged in it." This medicine is generally recommended to be given for boils, and certainly seems useful, although there is no very well-marked indication in the proving by which its suitability can be shown. Belladonna-" Boils." Kali bichromicum-" Without being aware of any scratch, the arm swelled as high as the axilla, then a boil-like elevation formed, which turned into a large ulcer, with dark centre and over-hanging edges." Hepar sulphuris-" Pimples, the size of a pea." This medicine is recommended in indolent boils, and may be used externally in the form of ointment with advantage. Lycopodium-" Large boil on the left lower arm, making the whole arm stiff, and another boil on 456 THE SKIN the left shoulder (in a few days); boils returning periodically." Pkosp/horus-" Small boils on the nape of the neck, chest, and thighs; large boils on the thighs, chest and forehead." Pulsatilla-" Boils here and there." It is particularly suited to cure styes, which are one of the symptoms it produces. - Staphisagria-" Frequent boils." Sulpkur--" Boils." Anthrax-consisting of fibrinous deposits, surrounded by suppuration, which require to be expelled before a cure is possible-is generally treated by a crucial incision; this allows the pus to escape, and permits the evacuation of the firm central masses, and seems the most rational and least painful plan of treatment of a purely mechanical kind, and therefore by no means opposed to the administration of specific medicines at the same time, in fact tending rather to favour than prevent their salutary operation. Cold dressings may also be employed, which should press firmly upon the part, and the pressure should be gradually increased from day to day till the cure is effected. The medicines recommended to be given in this painful and tedious complaint are arsenicumn, belladonna, and silicea; the recommendation seems to rest upon clinical experience chiefly, for there is no very striking similarity between the symptoms which they produce and Anthrax. Mlolluscum is a rare and curious disease, consisting of pouches formed by the enlarged and distended ducts of the sebiparous gland; they look like red currants or. 458 THE SKIN lip, around the chin, and on the forearms; they sometimes burn after scratching." Out of the long catalogue of medicines useful in acne these are the only ones whose symptoms at all correspond with those of the disease, and the following are recommended upon empirical grounds alone: belladonna, carbo vey., nux vomica, pulsatilla and natrum mnuriaticum: for the acne of drunkards; carbo veg., ledum, arsen., num vom.,pulsatilla, sulphur and belladonna, are the favorite remedies. In the closely allied affection montagra or sycosis menli, the following medicines may be administered: Antimronium crudum.---"Red, burning, suppurating eruptions on the face; eruption on the left cheek towards the chin, with a yellow crust, painful to the touch, and which may be easily knocked off." Cicuta virosa.-" Thick, honey-coloured scurf on the chin, upper lip, and the lower portion of the cheek, with burning soreness and oozing of the skin, accompanied with swelling of the submaxillary glands, and scurfs in the nose, and insatiable appetite." Graphites.-" The chin is covered with eruptions, also scurfy round the mouth and the cheek." Hepar sulphuris. -" On the chin, above and below the lips, and on the neck, pimples resembling blotches, sore when touched, but not otherwise." Oleander.-" Suppurating pimple on the left and right sides of the chin." Sepia.-" Pimples on the chin, with ulcerative pain when touched; itching pimples on the chin; long lasting scabs upon the chin." Tinea capitis, or common ringworm, is easily recog AND ITS DISEASES. 459 nised by spots of nearly perfect baldness on the head; upon minute inspection the hairs are seen to be there, but stunted and shrivelled so as to resemble tow. The affected parts are at first quite dry and covered with small shining scales like mica; if the head be not kept clean an exudation generally takes place from the surface, and produces a matting of the hairs in which the scabs are imbedded. The general indications for treatment are to cut off the hair, but not to shave the head, and to wash it every morning with common brown soap and water. Change of air, especially to the sea-side, and a generous animal diet, are also advantageous. The following are the specific medicines best suited for its treatment: Alumnina-" Falling off and excessive dryness of the hair; soreness to the touch." Arsenicum-" Bruised pain of the scalp, increased by touch, the hairs are painful when touched; creeping of the skin of the occiput as if the hairs moved." These symptoms of Arsenic, although they present no proper resemblance to tinea, yet perhaps indicate an action of some kind upon the seat of the disease, which is the hairbulb. Calcarea carbonica-" Scaling off of the scalp in the region of the vertex." Grap/ites-" Scurfy spot on the top of the head, with violent sore pain when touching it." This is the most favorite medicine in tinea, and is often used in the form of ointment. Sulphur-" Pain of the roots of the hair, especially when touching the hair." We must confess that our experience of the homoeo 460 THE SKIN pathic treatment of this disease has been far from encouraging, and we have been not unfrequently somewhat mortified by the rapid cure effected after all our efforts had proved unavailing by some quack preparations applied to the part. Perhaps we do not pay sufficient attention to the local application of our'specific remedies. We know that our discomfiture in our operations against tinea has been shared by some experienced homceopathic physicians, and it excites some surprise to observe the confident tone assumed by others who seem to obtain results so very different from ours by identical means. We think this is a subject well worth the attention of those who have extensive opportunities of observation, and we trust they will give the medical world the benefit of their experience in a minute detail of cases of tinea which come under their care. What we have said of tinea is still more true of favus, the last remaining disease on our catalogue. Of the pathology we have spoken in the former paper, and to be able to say anything satisfactory about its treatment we must wait till we have the materials afforded by a sufficient number of cases successfully treated by homoeopathic remedies, for there is nothing in the symptoms recorded in the provings hitherto published to warrant our recommending one medicine more than another with any degree of confidence. In the therapeutic part of this paper we have left the question of the dose entirely in abeyance; those in the habit of using high dilutions prefer them in diseases of the skin as well as in other morbid affections; those who usually give low dilutions in their turn prefer the low. As yet there is neither a sufficient accumulation of accurate observations to enable us to decide upon AND ITS DISEASES. 461 the ground of empirical statistics, nor has. there been any successful attempt to ascertain the laws by which the enormous differences in the amount given by different practitioners with nearly the same success, are to be accounted for. Till one or other of these grounds of comparative certainty be attained all dogmatism on this subject would be presumptuous in the highest degree, *and would reveal not only ignorance, but worst 'of allignorance of our ignorance. CHAPTER IX. ON AFFECTIONS OF THE NERVOUIS S"YSTEM. ALTHOUGH some of the conclusions arrived at by Sir Charles Bell, are controverted by the most recent investigators of the -nervous system, and even the very important one of the posterior columns of the spinal cord being the sole medium by which sensitive impressions are transmitted from the circuimfercnce to the centre, is denied by Dr. Brown- Sequard, yet the fundamental principle insisted on by that great discoverer of the distinction between those nerves which convey an impression from without inwards, to give rise either to a sensation by being transmitted to the brain, or to some action in the body by its transmission directly fr-om the spinal cord to the more external parts, and the nerves which convey an impression from within outwards', has been amply confirmed, and ig assumed by writers on this subject as an axiom of the science of neurology, along with its corollary, that impressions can only travel along one line of a nervous fibre, and cannot be transferred to another fibre although in the closest proximity, but must invariably either pass outwards to the extremity, or inwards to the centre. This principle is of constant application in practice when we meet with some abnormal condition of external parts, such as insensibility or AFFECTIONS OF THE N}RVOUS SYSTEM. 463 numbness, and seek its cause in some affection of either the spinal cord or brain. But there is a practical difficulty in applying it, from the fact that local influences acting upon the remote branches of a nerve, may produce all the symptoms that would arise from an injury of its root. Sir Charles Bell gives an interesting illustration of this in the following narrative. "When we see a person alarmed without a cause, and there is no danger in the case, there is something approaching to the ludicrous in the scene. A physician paid me a visit who had come up from the country in the mail, and had fallen asleep in the night time with his cheek exposed at the open window to the east wind. On the morning of his arrival when preparing, to go abroad, he found upon looking into his glass that his face was all twisted. His alarm gave more expression to one side of his face and produced more horrible distortion. Both laughing and crying you know depend on the function of the portia dura, but when he came to me he considered it no laughing matter: I never saw distortion more complete. It was difficult to comfort him. I am happy to add that the paralysis gradually left him, as I told him it would." * The following case related by Dr. Graves in his clinical lectures t is even more remarkable from the paralysis affecting not the nerve which suffered the lesion, but one organically rather than anatomically connected with it. "A medical student travelling through Wales on the outside of the mail, was exposed for many hours to a keen north-easterly wind blowing directly on his face. When he arrived at the end of his journey, he found " Bell on the Nerves, p. 283. t p. 398. 464 AFFECTIONS OF that his vision was impaired, and that everything seemed as if he were looking through a gauze veil. There was no headache, no symptom of indigestion to account for this evidently slight degree of amaurosis, and yet he was recommended to use cupping to the nape of the neck, and strong purgatives. When he consulted me, which he did in the course of a few days afterwards, I at once saw there was something unusual in the case; and after a careful examination I at length elicited from him the fact of his having been exposed to the influence of cold Wind. It was now apparent that the retina suffered in consequence of an impression made on the facial branches of the fifth pair. The cure was effected not by a treatment directed to relieve cerebral congestion, but by stimulation of the skin of the face, forehead, temples, &c., &c." A case presentiing a difficulty of this kind occurred iti my own practice last autumn. About three years ago, a lady of about 70 years of age came under my care. At that time she was suffering from palpitation and irregular action of the heart. I found on examining the chest that there was some hypertrophy, and a faint murmui along with extreme irregularity of rhythm. The pauses were long and frequent, and occurred at uncertain intervals. With the exception of a few symptoms, such as a tendency to urticaria, which seemed to indicate gout in the constitution, her health was very good, and she had not been confined to bed for one day for many years. At the end of last autumn she went to Malvern, and on her arrival there complained of numbness of the left hand and cheek, and partial insensibility of one side of the tongue, along with unusual deafness anid some pain THI, NERVOUS SYSTEM. 465 and confusion of head. On visiting her there the following evening, I found that she had come from the railway station to her house in a carriage only partially closed, and that the left side had been exposed to cold. There was not positive insensibility of the affected parts, but distressing numbness, and the pulse was quick and even for her extremely irregular. The numbness was over the cheek generally, extending to the lip on the affected side, and she complained much of one side of her tongue having lost its proper sensitiveness, so that it annoyed her when she masticated her food. There was no loss of the power of voluntary motion in any part, nor was there any numbness of the legs. I felt great difficulty in giving an opinion as to the nature of the case, which her friends looked upon as a paralytic attack. The age and old heart-complaint, along with the pain and confusion of head and increased deafness, seemed to point to a central cause, while the limitation of the numbness to those parts which had been exposed to cold made one hope that it was merely an affection of the external nerves. I left her Arnica and Nux vomica to be taken alternately, and recommended her immediate return home. On her arrival at Leamington in the course of a couple of days, I found a very slight change in the state of affairs, but that change was for the better: this confirmed me in the favorable opinion I had formed. In the course of a fortnight she was attacked with bronchitis, and was so ill that for some time her life was dispaired of..However, she eventually recovered, and on her recovery still complained of the numbness although in a lesser degree, and a constant noise in the head. Her health is now on the whole veiy 30 TIHE NERVOUS SYSTEM. 467 I should mention that there was no appearance of any disturbance of the digestion except slight costiveness, which was removed by the medicines, In fact, but for this one symptom his health was perfect. I may here mention another somewhat similar case. A woman of 30 years of age consulted me at the dispensary, and gave the following statement of her case. She had had several children, and except not being very strong was in good health. Since the birth of her last child about two months ago, the catamenia had naturally been absent. She was I presume nursing an infant. For a month she had been attacked every night about 11 o'clock with numbness of both hands and arms, attended with such acute pain as to keep her awake. She described it as numbness followed by pain. I ordered her the 2d dilution of Aconite: a dose 3 times a day. This was upon the 17th of January. She did not return till the 11th of June, and then for some slight derangement, and on asking her about her former complaint, she said that after taking the Aconite for 2 or 3 days, she got perfectly well. Of the individual nerves there are none so often affected as those of the face, especially the fifth pair, and this being a nerve of sensation the expression of its morbid condition is pain. There are two affections to which this nerve is liable, simple neuralgia and tic douloureux, and it is of great importance to distinguish accurately between these, for an error in diagnosis may give rise to serious disappointment. Nor is this distinction an easy task. We find in the records of clinical medicine many examples of ordinary neuralgia being mistaken for true tic. Dr. Graves in his lectures makes 468 AFFI(CTIONS OF the following observations, which are worthy of our attention:-" I have seen many cases in which a painful or carious tooth, or an injury done to the gum or jaw, has been followed by violent darting pain in the nerves of the face, simulating in many particulars tic douloureux. I remember being sent for to Middleton, near Cork, some time since, to see a -lady of delicate constitution, whose health was materially deranged from what was said to be an attack of tic douloureux. She had been under the care of many practitioners, and had used very large doses of the carbonate of iron and sulphate of Quinine, and at the time I visited her was taking Arsenic. The first thing I did on my arrival was to examine her teeth. On close examination I observed that on the crown of one of the upper molar teeth there was a spot which appeared to be decayed, and I found on inquiry that she frequently suffered from pain in this spot when she drank any cold liquid. I had the tooth drawn and soon afterwards the pain completely ceased. Yet in this case the pain was not only of an intense character, preventing sleep and wearing out her strength, but it had its intermissions, and wag aggravated at particular hours of the day." He gives another similar case, but he does not inform us how we are to distinguish the one disease from the other. Nor can we find in Romberg, although he treats in his usual scornful way the errors of practitioners in confounding true facial neuralgia with other painful affections, any symptoms which afford unequivocal signs by which a differential diagnosis can be established. He gives five rules:-1st. "It is confined to certain distributions of nerves, and occurs in paroxysms separated by ' Graves's 'Lectures on Clinical Medicine,' p. 650. THE NERVOUS SYSTEM. 469 a free interval."-So does toothache.-2d. " The peculiarity of the exciting cause." This is generally unknown, and so wont help us much.-3d. " The sensitiveness of the affected surface of the face to unexpected and slight contact." This is certainly more to the point.--4th. "The preference shown by neuralgia of the fifth pair for mature age, as it occurs only after the thirty-fifth year." This I am certain is a mistake. I have seen it in a person below thirty years of age.1-5th. "The rarity of the disease, which must increase our scepticism in forming a diagnosis." There is anything but help in this observation.2 It seems to me that this is one of the cases where the difficulty is rather in the description than in the recognition of a distinction. To any one who has watched cases of tic douloureux, there is no danger, at least not much, of his confounding with this dreadful disease ordinary facial neuralgia. Perhaps the most marked distinctions between them are the general appearance and character of the patients, and the results of our treatment. As far as my observation goes, the subjects of ordinary neuralgic pains of the face, of so severe and long continued a kind as to make it possible to mistake them for true tic, are of a languid, exhausted, pain-worn appearance, and generally females; whereas the sufferers from tic douloureux are usually the very reverse. They have a look of unusual vigour and vitality, and an expression of a certain active despair in their countenance, presenting a great contrast to the passive expression of the 1 Dr. Quin, Dr. Madden, and Mr. Cameron all confirm this remark from their own experience. 2 Romberg 'On the Nervous Sytcm,' vol. i, p. 48, 49. 470 AFFECTIONS OF suffering of the others. The health too of these sufferers is often wonderfully little affected, and unless we see the patient in an attack we can hardly believe the pain is so dreadful as it is described, for we naturally but erroneously suppose that so great a pain must exhaust the patient. This is not the case, however, and after an attack is over and sleep has restored the nervous system to its ordinary state, the appetite returns, and all the functions go on with more than ordinary vigour and regularity. For the sake of illustration I shall give the particulars of two cases, the first being one of simple neuralgia, the other one of true tic, which have lately come under my notice, and I do so partly in evidence of the second diagnostic test I adverted to, viz., the curability of the one and the obstinacy of the other. I was consulted, on the 30th of July, 1855, by a lady of about 40 years of age, who looked the picture of a person exhausted by suffering and general ill health. She had a slow, languid, weighted gait, her voice was feeble, and she spoke with an effort. For two years she said she had been suffering almost constant pain, which occasionally become excessively violent, extending from a point in the upper jaw corresponding to the root of the eye-tooth upwards overt he cheek, nose, and temple. The pain was aggravated by eating or speaking, but for some time back it had been constant and severe. The whole of the face was tender to the touch, as was also the scalp. The tongue was dry and white, the bowels very costive. The catamnenia were too copious and frequent. There was leucorrhcea. The pulse was small and rapid. She complained of aching in the limbs and general weakness. THE NERVOUS SYSTEM. 471 I ordered her a drop of the second dilution of Chamomilla, three times a day for a week. On the 6th of August she called on me again. Her report was, that after the first dose of the Chamomilla the pain began to abate, and that now it has nearly gone. She got Nux v., second dilution, for a week, then Tr. of Sulphur, and after that China, and by the middle of September she was almost entirely restored to health. She described her feelings on waking of a morning as a sense of overwhelming gratitude, when she found that the long-accustomed pain was gone, and that life which had been a burden was now a pleasure. She continued in the enjoyment of her new health till the following winter, when the pain in the face returned, and was cured in about a week by Mercurius solubilis and Chamomilla. This must be acknowledged to be a most satisfactory case, but even had there been any doubt in my mind as to its not being one of tic, the very rapid cure would have removed this doubt. Here is the contrast. A lady of about 60 years of age, who had been under my care for headaches and trifling ailments, and who was of a nervous and vigorous habit of mind and body, consulted me, upon the 28th of December, for the following symptoms. For a week she had been subject to sudden violent pain, darting from the internal canthus of left eye, up and down the side of the nose, and into the brow. It comes on without any warning, is very intense, and feels like a knitting-needle run into the side of the nose. In other respects she is quite well. Such was her description, and on comparing this case with the last, one would naturally suppose that 472 AFFECTIONS OF it was much the milder of the two. It had lasted only a week, and had in no way impaired her health. However I had my misgivings, and although she got apparently well after a few doses of Mercurius solubilis I was not surprised to see her return on the 10th of March. She complained of a return of the pain, but that it was more severe. It was like an electric shock running along the nerves and into all their twigs, and again like very small red hot wires thrust into the nose, eyes and brows. She had an alarmed look, very characteristic of sufferers from tic, and she had the greatest dread of the slightest contact. She dared not blow her nose, for the merest touch sometimes brought on this horrible pain, which made her writhe about in agony. The intervals of the attacks were quite uncertain. I gave her Arnica and Arsenic. She reported herself on the 24th of March as having been better while taking the medicine, but from that time to this the attacks have returned, and each time more severe. There is no change in their character; they are always described as sudden, electric, burning, darting, shooting along the twigs of the nerves, and hitherto they have been always relieved by the medicines Ignatia, Mere., and Arsen., but she is not cured, nor I fear will be well for many a long day. Now what is the difference between these two cases? It is evident that in both there was a morbid affection of the fifth pair, in the first secondary to a general derangement of health, in the last, idiopathic, depending upon some inscrutable alteration in the nerve itself. The curious thing, however, is that in the first case this very painfll secondary affection should have been almost in T'HE NERVOUS SYSTEM. 473 stantaneously cured, before there was any time for an improvement of the general health, so that we must look upon it as a specific cure of a neuralgic affection. And why can we not effect with equal ease and rapidity a similar cure in a case of apparently much slighter kind? Before we can reply to this we must know more of the pathology of the disease. But I believe my opinion of the difficulty of curing tic douloureux is borne out by all who have had much experience in this rare and dreadful disease; certainly it is so by Dr. Quin, who probably has had more opportunities of observing the complaint and who has been, I believe, more successful than any physician now alive. The portio dura of the seventh pair of nerves being a nerve chiefly if not exclusively subservient to motion, its morbid conditions result either in spasms or paralysis of the muscles of the face. One form of spasm has received the name of tic convulsif, and histrionic spasm of the face. This affection is characterised by spasmodic jerking of one side of the face, giving the effect of a series of grimaces. It is seldom painful, and seems generally to arise from some sympathetic action communicated to the portio dura from some internal organ. It was an old belief that wounds of the diaphragm produced a peculiar muscular affection of the face, known as risus sardonicus, and as the origin of the phrenic and portio dura are not far apart it is quite possible that the notion may have had a foundation in fact. The ancients ascribed to the Ranunculus sceleratus the property of producing a somewhat similar affection, known as apium risus. It might be well to bear this in mind in the treatment of such troublesome cases as the following. 476 AFFECTIONS OF 4th dilution of Silica, without, I confess, any great hopes of doing good, and was almost as much surprised as the parents when on the child's return in ten days I found the tumour decidedly less. I heard nothing of the case till the 9th of November, when the boy's mother called for some more medicine, reporting that the tumour was almost gone, and that she would bring him over to see me again. I have heard no more of the case, but as the parents live about forty miles off it is not wonderful that they should not return if the boy is well, but it is a reasonable inference that unless the case had done well his parents would have come back. I take it for granted that in the course of time the portia dura will regain its proper control after the cause of its partial palsy is removed. It is comparatively easy to infer a morbid condition of particular nerves, which minister to voluntary motion and ordinary sensation, from the symptoms presented by the affected parts of pain or insensibility on one hand, or of spasms or palsy on the other. It is, however, much more difficult to distinguish with accuracy the lesions of the par vapym, which possesses very complicated and peculiar endowments. It may be well to refer briefly to the anatomy and physiology of this nerve before adverting to the effects of some of its morbid affections. The pneumogastric nerves arise behind the olivary and close to the restiform bodies: immediately after leaving the skull, which they do by the foramen lacerum posterius, they are intimately connected with the hypoglossal, spinal accessory, and glosso-pharyngeal nerves. On arriving at the lower part of the neck, on the right side, the nerve passes before the subclavian THE NERVOUS SYSTEM. 477 artery, and on the left before the arch of the aorta. In its course it gives off first, the pharyngeal twig, which, with branches of the glosso-pharyngeal, upper laryngeal, and first cervical nerves, constitute the pharyngeal plexus. Second, it gives off the superior laryngeal which divides into the external laryngeal and the internal laryngeal. The external laryngeal is distributed upon the sterno-thyroid, hyothyroid, constrictor pharyngis inferior, and crico-thyroid muscles. The internal laryngeal divides into an upper and lower set of filaments; the upper ascend to the glottis and membrane of the pharynx, the lower are distributed upon the mucous membrane of the larynx and pharynx and aritenoid gland and muscle. One of them descends between the thyroid cartilage and -crico-arytenoid muscles, and is distributed entirely upon the crico-arytenoid muscle. After giving off cardiac twigs, the next important branch is the inferior or recurrent laryngeal. This nerve,' on the right side, loops round the subclavian artery, ascends between the trachea and oesophagus, and after giving off branches in its course supplies the posterior and lateral crico arytenoid and thyro-arytenoid muscles. It gives branches to no other muscles of the larynx. The left differs from the right in describing a much larger curve round the arch of the aorta. Its distribution in the larynx, however, is the same as the other. After giving off these branches the nerves increase in volume, form the pulmonary plexus, and lose themselves in the subdivisions of the bronchial tubes. The functions of the pneumogastric nerve are as numerous as its distribution is extensive. In the pharynx it is a nerve of sensation -endowing the parts it there 478 AFFECTIONS OF supplies with its peculiar sensibility by which the mechanism of deglutition is set in motion, and when morbidly affected, giving rise to a sensation of nausea, and according to Romberg, to the peculiar sensation known as the globus hystericus. It is probable that the nervous sore throats we frequently meet with in practice, chiefly in females, characterised by a sense of heat, dryness, and pain, and sometimes redness of the fauces, but without swelling and not interfering with the swallowing of food, are owing to a state of hyperaTsthesia of this branch of the par vagum. We may take the following case as an illustration. I was consulted on the 3d of August, 1855, by a woman of 35 years of age, dark in complexion, and of a nervous temperament, She complained of having for six months suffered from a constant stinging pain in the fauces, with an unpleasant sensation round the throat. The pain was relieved by swallowing either solid or liquid food. There was no swelling or redness discernible. It was accompanied by a painful sense of weight between the shoulders referred to the spine. For a week she had also been affected with hoarseness, slight cough, and some dyspncea. In other respects her health was good. I ordered her a drop of the 3d dilution of Naja tripudians three times a day. She returned on the 10th of August, and reported her throat better, as also her voice and cough, and complained chiefly of the pain between the shoulders. The same medicine was repeated. On the 17th, she said her throat was now almost quite well, the cough and hoarseness gone. She complained THE NERVOUS SYSTEM. 479 of pain round the eyes, dazzling of sight, and much pain in the upper part of the spine. The Naja was continued. On the 24th, she was on the whole much better, but a papular itchy stinging eruption had come out upon the neck and shoulders, and small vesicles upon the tongue. She got Mercurius solubilis 4th dilution. On the 31st, the tongue was better, but the old sensation had returned to a lesser degree in the throat. She again got Naja as before. On the 6th of September she came to say she had caught cold, which produced hoarseness and beating pain at the vertex. She was ordered the 2d dilution of Belladonna. She did not return till the 17th of October, an interval of about five weeks, and then it was on account of pyrosis. In other respects she had been quite well. She had entirely lost the uneasy feeling in the throat, from which she had suffered constantly for six months, and she felt altogether a different person. She was ordered Mercurius solubilis, and did not again return. If this was, as I think, an affection of the pharyngeal branch of the par vagum, it is rather curious to observe that as it got better, the morbid action seemed transferred in some measure to the gastric branch of that nerve. " In the gastric distribution of the vagus," says Romberg, "the neuralgia is ordinarily met with in three forms; as a sense of constriction of the pharynx, of burning in the oesophagus, and of tenderness in the stomach. The first is known as globus hystericus, the second is included under the head of pyrosis, and the last I term gastrodynia neuralgica."1 As to the 1 Vol. i, p. 104. 480 AFFECTIONS OF treatment I attribute the cure to the Naja, the action of which upon the nerves of the throat is remarkable. While the gastric branches of the vagus are probably purely sensory, those which supply the larynx are both sensory and motory; in virtue of the former function endowing the larynx with its discrimination of noxious and harmless air, and communicating to it the sensibility which sets in motion the mechanism of coughing; and as nerves of voluntary or semi-voluntary motion presiding over the vocal apparatus. Thus it is that hyperaesthesia of these nerves gives rise to spasmodic coughs, (Romberg says even to hooping cough,) while paralysis of some of the branches is one -of the causes of aphonia. The following case I consider an example of hyperaesthcsia of some of the laryngeal branches of the vagus, probably the recurrent. A gentleman of 47 years of age consulted me on the 28th July, 1855. He was thin and sallow, and of a dark complexion. For many years he had been subject to a sense of painful constriction about the trachea, immediately above the sternum; he could not draw a full breath, the inspiration felt arrested, and resulted in a short cough. On pressing the part he said it gave him an uneasy sensation. I-Ie had had occasional attacks of heemoptysis. There was no cough in general, but every morning he expectorated a considerable quantity of sweet mucus. The pulse was small and weak. lie had tried various climates, and been put through the regular course of blisters, blue pills, &c., but hitherto he had got no permanent benefit. On examining the chest I found that except unusual absence of THE NERVOUS SYSTEM. 481 fat there was no symptom of disease. There was a little irregularity in the heart's action, but not enough to come under that name. The respiration was free over the whole thorax. I fancied from the haemoptysis and the obstinacy of the derangement of the respiratory sensations, that there must be some tumour pressing upon the par vagum, possibly an aneurism of the arch of the aorta, and so I gave a very dubious prognosis as to the result of the treatment. I ordered three powders of the 3d trituratiuL-of Natrum muriaticum, a dose three times a day. He returned in a week, and to my astonishment told me that after the first dose he felt relief, and that now the uneasiness was entirely gone. He could take a deep inspiration without either cough or discomfort. The sputa were diminished to one third. The pulse was fuller and stronger. In fact he was almost well. IH continued quite well till this spring, when he had a sharp attack of bronchitis, which yielded to the ordinary remedies. I have seen him going about within the last week or two apparently in perfect health. Had this recovery occurred to a nervous woman, I should have been inclined to impute it to some psychical action on hysterical symptoms; but the person thus cured was a remarkably sober-minded intelligent man, devoted to,the cultivation of a branch of science, who came at the solicitation of his friends, and without almost any expectation of deriving much benefit from the treatment; so I can ascribe the cure to nothing but the specific effect of Natrum muriaticum. I met with another case somewhat similar, of hypertesthesia of the pulmonary branch of the par vagum. As the peculiar sensibility of the lungs which informs us 31 THE NERVOUS SYSTEM. 483 opening of the glottis. During ordinary respiration this aperture has a triangular form, and permits the free passage of the air upwards and downwards. During vocalization the base of this triangle almost disappears, and the two sides approximate, and become parallel. This has been observed in patients who have had an opening in the throat, generally produced by an attempt at suicide. This change in the form of the glottis is effected by the contraction of the lateral crico-arytenoid, and the transverse and oblique arytenoid muscles. These muscles receive nerves from the recurrent branch of the vagus, so that palsy of the recurrent, we may assume will prevent the change in the aperture, and be attended with true aphonia.1 While the generation of voice seems to depend upon the passage of a column of air through a narrow slit, its pitch is modulated by the greater or lesser tension of the reflection of mucous membrane called the vocal ligaments. This tension is due to the contraction of the crico-thyroid muscles. This muscle as we have seen is supplied by the internal laryngeal twig of the vagus. We may then fairly conclude that when patients present themselves affected with complete aphonia without any destruction or alteration in the mechanical vocal apparatus, such as ulceration of the cartilages, that the cause of this absence of voice is more or less palsy of the internal laryngeal, while persons whose voice has become simply deep and hoarse, and who cannot emit the higher notes, are probably affected SThis description is taken from Mayo's 'Physiology,' who follows Mr. Willis's account published in the ' Cambridge Phil. Transactions' for 1832. This description of the nerves is taken from Cloquet's ' Anatomy.' See also Bell 'On the Voice.' 486 AFFECTIONS OF however is that it occurs with undue frequency in the clergy of the English Church. The next case I met with was very different. On the the 10th of last December I was consulted by a strong robust butcher, who was the very personification of rude health. He might have sat for a picture of John Bull. He was about 40 years of age, and there was something perfectly ludicrous to hear him speak, for instead of the great manly voice which one expected from so lusty a man, he could only emit a faint whisper with the greatest effort. There was no tenderness about the larynx, nor any cough, and in all other respects he was quite well. For several years during the whole of the winter, he had been subject to this loss of voice. It began by huskiness, and went on to such complete aphonia as to render him quite inaudible. This I suppose was from an affection of the recurrent, for it was more than the mere hoarseness which we might ascribe to the insufficient tension of the vocal ligaments. The cause he suggested to be his exposure to cold in his open shop, and being obliged in the exercise of his trade to talk a good deal, in making bargains I suppose. He was of temperate habits. I gave him the second dilution of Belladonna, a drop to be taken three times a day for a fortnight. He returned at the expiration of that time greatly improved, and the medicine was repeated. I heard from him afterwards in about a month that he was perfectly well, and his voice as strong as it was in summer. He lived at some distance from me, and I have had no opportunity of satisfying myself as to the correctness of this report, which however I have no reason to doubt. THE NERVOUS SYSTEM. 487 The following case presents some interesting points of contrast to that of the lusty butcher. A married woman of 44 years of age consulted me on the 19th of May, 1854, and complained of dry husky feeling in the throat, and great sense of weakness. She spoke in a whisper and could not speak louder. She stated that she had suffered from this loss of voice for eight months, and that she was subject to it from any depressing emotion. She was feeble and languid, the pulse weak, and she had little appetite. I gave her Naja, and on the 29th she said the unpleasant husky feeling was gone, but there was no improvement of the voice. I then gave her the first dilution of China; and after taking this for a month, she got quite well. In this instance the aphonia was evidently dependent upon the general condition of the system, and not merely a local affection of the vocal organs. This accounts for the benefit produced by the China, a.medicine from which I have frequently seen similar good effect in such cases. Under the head of hyperaesthesia of the cutaneous nerves, Romberg makes the following observations. " The expression of this variety of hyperoesthesia consists in a sense of pain, itching, formication, and heat; pain is the most frequent symptom, and for this reason the term neuralgia has been used to designate it. These sensations come on in paroxysms, and are confined to the distribution of one or more of the cutaneous nerves, of one or occasionally of both sides of the body. Injuries of the nerves may serve as types of this affection; because they may, as surgical operations generally are, be 488 AFFECTIONS OF looked upon in the light of experiments which afford a more distinct interpretation of natural conditions. Neuralgia from injury of a nerve may be known by a pain commencing at a definite point in the course of a nerve, by its distribution to the peripheral terminations of the nerve, by excitement or exaltation of the pain by the slightest touch of the injured part, and by cessation of the pain when compression is applied above the seat of the injury. Sooner or later sympathies in other nerves not only in the vicinity but also at a distance from the original seat show themselves, and if the pain continues for a long time, a constitutional disease is developed. Punctured wounds, cuts, bruises, and foreign bodies are the most frequent causes. The pain occurs in paroxysms, and is produced or increased by change of weather, affections of the mind, and errors in diet. The purest form of neuralgia is when the injury affects any sensitive nerve, such as the subcutaneous nerves; it becomes blended with symptoms of a motor character, when those causes are seated in a nerve containing sensitive and motor fibres." CASES. "A young lady, aged 16 years, while engaged in acquiring the art of cooking, pricked the middle finger of the right hand, on the radial side between the second and third phalanx. Violent pains ensued at once, and inflammation set in some days afterwards with an eruption of phlyctenae accompanied by a dusky redness of the hand and forearm. Suitable remedies removed the inflammation, but a painful sensation remained in the finger, which was increased by contact, or spontaneously THE NERVOUS SYSTEM. 489 and frequently induced sympathetic sensations in the hand, arm, neck, and leg of the same side. Whenever the patient becomes otherwise indisposed, the finger is the most painful part. The repeated use of the seabaths, at Norderney, has effected a remission but no cure. At a later period, spasms in the distributions of the facial and accessory nerve of the same side supervened."' The following case I am inclined to consider an illustration of this affection. On the 8th of October, 1855, I was consulted by a lady who lives in a town at about twenty miles' distance. She was about forty years of age, looked very infirm, and had a peculiar puffy expression of countenance. She stated that she had always been delicate. She had had a large family, and ascribed her present exhaustion to the copious haemorrhage which attended her confinements. She had long been subject to cough and pain under the right infra-clavicular region. She was in her usual state of health in May, 1854, when she pricked her fore finger with a sewing needle; the wound was utterly insignificant, but very soon after she was attacked with violent pain going up the arm as far as the neck. After the pain had lasted for a week, the arm became red and swelled. These symptoms continued for a fortnight and then gradually subsided. She remained pretty well till the following September, when she had a similar attack of pain and swelling without any known exciting cause. Then in December both hands and arms became affected, first with pain, then with swelling, redness, and blisters. Since that time she 1 Romberg, op. cit., vol. i, p. 18. 490 AFFECTIONS OF has been subject to such an attack about every three weeks, and this corresponds with the appearance of the catamenia. The attack is ushered in by intense headache, and a loss of appetite, and general sense of illness. I found the pulse full, quick, and jerking, the tongue coated. She complained of loss of taste as well as appetite. She has been taking tonics of all kinds, but is so weak that she is hardly able to walk even about the house. I gave her Aconite 2d dilution, and Graphites 4th dilution. The first to be taken for two days, the other for a fortnight. On the 20th she was better, and Graphites was repeated. I saw her again on the 14th of November, she came with her hand bound up. She had hurt the finger again with a piece of glass, and there was a return of the pain and swelling of the hand and arm. I gave her the 3d dilution of Naja tripudians, a dose three times a day for a fortnight. On the 28th of November, she reported herself as much better every way, and she went on with this medicine till the 23d of February. The change in her appearance at this time was most striking; she had lost her languid look, was strong and more robust, she could walk several miles a day, her appetite was good, her taste had returned, and she had had no attack of her old complaint for four months. The only medicines she has had since are Sulphur and China, and she now considers herself as quite well. Cases of this kind throw light upon such diseases as herpes zona, which seem to arise from some general derangement of the system, producing a neuralgia which localises itself in the subcutaneous nerves of the side, THE NERVOUS SYSTEM. 491 and gives rise to a vesicular eruption. It was from the benefits I have seen from Graphites in this affection, that I was led to begin the treatment of the foregoing case with it. To the Naja, however, I consider the chief credit of the cure to be due. ON SOME LESIONS OF THE NERVOUS CENTRES. IN the preceding section I related some cases illustrating morbid affections of certain nerves: I propose now to direct attention to some affections of the brain and spinal cord. The first member of this class, in point both of importance and frequency, is undoubtedly epilepsy. I do not intend, however, to enter upon a general discussion of this dreadful malady, but I mention it that I may have an opportunity of repeating, that hitherto my experience has been more in favour of Belladonna than of any other medicine in the treatment of epilepsy, and that I have found benefit in many cases of long duration and great severity by persevering for years in the daily use of Belladonna; and I wish also to mention a curious case that is now under my observation, as illustrating the pathology of the disease. Dr. Brown-Sequard states that he found he could produce true epileptic attacks in certain animals by wounds of the spinal cord-at least a series of general convulsions returning at regular or irregular intervals. From this he argues that epilepsy is in some cases owing to a morbid condition of the cord, a state of preternatural irritability, and he agrees with Dr. Marshall Hall in supposing that the immediate cause of a fit is the closing of the larynx and the suffocation 492 SOME LESIONS OF of the epileptic person, that this prevents the entrance of air into the lungs, that the blood is no longer arterialised, and that venous blood acts as a direct irritant poison to the spinal cord. This theory represents the conditions of epilepsy to be a chronic state of preternatural irritability of the spinal cord, which gives a tendency to spasmodic closure of the larynx, that the suffocation thus induced converts the chronic into an acute condition, and the paroxysm is owing to the venous blood permeating the cord, which is morbidly sensitive to this poison. Now I have under my care a case of cyanosis, and the unfortunate subject of this congenital malformation, besides the ordinary symptoms of the disease, is subject to attacks of general convulsions of his whole body, on any exposure to an unexpected excitement, such as a sudden noise, intelligence of a painful or pleasurable character, in short everything which excites the nervous system either morally or by sensation, produces an attack of general convulsions which lasts from ten to twenty minutes, and resembles true epilepsy in every respect but one, and that is he never loses his consciousness, but gets excited. Is the cause of these pseudo-epileptic fits the presence of semi-venous blood in the arterial vessels of the spinal cord P1 I cannot resist the observation that the action of Belladonna both on the brain, the spinal cord, and the nerves of the larynx, has a marked affinity with this view of the pathology of epilepsy. Dr. Marshall Hall classes epilepsy with hydrophobia, as in both the spasms of the larynx are of the greatest importance, and Dr. Brown1 I asked Dr. Marshall Hall his opinion of this case, and he replied he would ascribe the symptoms to the cause suggested in the text. THE NERVOUS CENTRES. 493 Sequard represents epilepsy as curable by cauterizing the larynx so as to prevent its being thus affected by spasm. Of the power of Belladonna over spasms of the larynx there is no doubt, and thus this remedy may act beneficially by at once modifying the preternatural susceptibility of the cerebro-spinal centres, the predisposing cause of a paroxysm, and arresting in its incipient stage the spasm of the larynx through which the smouldering disposition to a fit is roused into active reality. I once had another very interesting case under my charge, the history of which presents the following outline: a young man, of perfectly temperate habits, addicted to athletic sports and to no vicious indulgences of any kind, and usually in the enjoyment of excellent health, mounted his horse for a ride. Before he had the reins in his hand, his horse bolted off at full gallop and made for a low open stable-door. Seeing that if he allowed himself to be carried into it he would be killed, he threw himself off, and fell upon his head. He was picked up and put upon the horse again. He rode a little way with a friend, who observing his manner strange took him back to his house. On arriving at home, he was lifted from his horse and laid upon a sofa; it was then found that his skull was fractured. He remained unconscious for some time, and then had a brain fever. He has been an invalid ever since, a period of above twenty years. He now states, that from the time of his fall to the time of his recovering his senses after the fever, he remembers nothing; that he must have acted automatically, or, as Dr. Marshall Hall would say, by the reflex action of the spinal cord alone, without any cere THE NERVOUS CENTRES. 495 spinal cord resulting from the pitch on the head; or, lastly, it may be that the cerebral and cerebellar lesion has excited a preternatural sensitiveness of the genital organs, which act by their nerves upon the spinal cord, and that this has induced a permanent weakness of the part. The peculiar dream of swinging upwards is very interesting. We know that injury to certain parts of the brain induce a tendency to turn or to roll, while cutting other parts makes a bird try to soar. Now, doubtless, 'this dream of ascent is in consequence of an injury to the same parts of the brain in this patient as corresponds with that part of the pigeon's brain the injury to which prompts the bird to mount. The reason of the sensation only occurring in sleep and giving rise to a dream, and not a movement, is obviously that the attention is too occupied in the waking condition with external impressions or internal perceptions and emotions to be alive to this dull, dumb, excited, animal instinct. It is satisfactory to be able to say that this patient improved by treatment. He got much stronger, he sleeps better, and has fewer uneasy sensations. The medicines which did it were Naja, Silica, and Arnica. The next case was also the result of an accident. I was consulted last March by a remarkably large, robust, and powerful man, 40 years of age, who stated that four years ago he fell from the top bf a house, a height of forty feet; he lighted upon a flat surface and quite prostrate, so that his abdomen was the first part of his body to come in contact with the ground. From that day he became the victim of constant pain felt in all parts of the body. The moment he awakes in the morning he 496 SOME LESIONS OF is sensible of severe pain in his back and loins, which extends to the shoulders and arms and down the legs. He has never been without this since the accident, but it varies much in degree and is aggravated by exertion. There is no headache or numbness, no wasting of the muscles, the appetite is good, the urine natural, and the sleep sound. The bowels are sometimes bound and sometimes relaxed. There is no pain on pressure either of the abdomen or back. The treatment in this case was followed by speedy and complete cure. For a fortnight he got Naja, but reported himself no better; he then got Belladonna, and returned on the following week free of all pain. I saw him last on the 11th of this month (May, 1857), and he was still perfectly relieved of the sufferings which he had endured without intermission for four years. The pathology of this case I take to be a shock to the spinal cord, either direct or indirect; in the latter case it must have been transmitted by the nerves of sensation to the posterior column, and given rise to a morbid action which displayed itself by a general hypermesthesia. The rapidity of the cure in this case was quite unexpected, and is a proof on how slight an organic derangement a constant and severe perversion of function may depend. I think the case is interesting, as throwing light upon the possible cause of disordered action in what is called spinal irritation. There are three distinct classes of spinal affections, presenting certain common features, and sometimes difficult to discriminate from one another, but radically different in their nature, and, consequently, in the treatment they require. Under the first head may be classed THE NERVOUS CENTRES. 497 those serious cases of structural disease of the spinal cord which go on from bad to worse and terminate in permanent contraction or palsy of the limbs, or slowly improve and eventually recover. Under the second head we may class all cases of idiopathic spinal irritation, and under the.last head cases of sympathetic spinal irritation. The following case, reported by Abercrombie, is a good illustration of the first class: "A medical gentleman, aged 30, who had been for several years in the navy, returned home in perfect health, and was living in Edinburgh, when he was observed by his friends to drag his legs awkwardly in walking. He was not himself at first sensible of it, but soon perceived a weakness and want of command over both his legs, which gradually increased to nearly perfect paraplegia. Some time after the affection of the legs took place he began also to lose the power of his arms, and this also increased till he retained in them only a very feeble and unsteady power of motion. They were also frequently seized with convulsive startings, so that an article which he attempted to hold was thrown from him with violence. The legs often started in the same manner, and were thrown about with considerable violence, especially when he attempted to move them while he was sitting up; No disease could be discovered in the bones of the spine, and he was otherwise in good health, until about two years after the commencement of the complaint, when he was seized with phthisis, of which he died, in September, 1822. I examined the body with the utmost care, and could not discover a vestige of disease, either in the brain or the spinal cord." That in this case there was some inscrutable structural 32 498 SOME LESIONS OV disease will hardly be doubted, and most probably the patient would have been incurable under any treatment. I have had several such under my care, and the result has been most unsatisfactory. But it is impossible at the outset to distinguish between a curable and an incurable case of this sort. For example, I was consulted, in September, 1855, by a man who walked with great effort, supported by a stick in each hand. He stated that seven months before he had been exposed to cold and wet, and soon afterwards he began to suffer from pain in the lumbar region of the spine,which gradually extended upwards, and that soon afterwards he felt a numbness and stiffness in his legs. These symptoms had increased up to the time of my seeing him. He complained then chiefly of weakness in his legs and back, and it was with the utmost difficulty he rose from his seat, and shuffled along with the assistance of his sticks. In other respects he was quite well, except that his legs were always cold, and his urine too copious. He had been for six months in a hospital before he applied to me. This man got quite well. Secale was the first medicine he got, and it seemed to do him good; the other medicines which apparently were most useful were, Sulphur, Arnica, Silicea, Rhus, and Naja. The cure occupied about six months, and he was then able to resume his work. I had another striking case of a woman 60 years of age, who for two years had suffered constant pain in the back, with numbness of the legs, and almost total inability to use them. She gradually improved, and almost wholvl recovered under the use of Secale, which she took steadily for about three months. THE NERVOUS CENTRES. 499 Although the term spinal irritation has been vaguely applied, surely Romberg goes too far when he says: " If we substract the spinal pain which accompanies the diseases of various organs, for instance, the stomach or the liver, and which is increased by internal pressure, and often associated with pain at the epigastrium, the doctrine of spinal irritation is deprived of its entire foundation, and takes its place among the fictions which have always found their way into pathology when physiology was undergoing a revolution, and hence for a time have been admitted as matters of fact."' Abercrombie, more philosophical, and as cautious as Romberg, always on his guard against admitting speculations in place of facts into pathology, contents himself with observing: " When we find, along with the complaints now mentioned (what we should term spinal irritation), symptoms distinctly referable to the spine, as pain or tenderness on a particular spot, it is fair to consider this as directing our attention to an important seat of disease: but there is no doubt that these affections often appear without any symptom that can be referred to the spine, and in many cases with sources of irritation distinctly referable to other organs." The difficulty of recognising a morbid condition with certainty, and of describing it with such exactness as to secure its recognition by all competent observers, is no reason for denying its existence. No doubt spinal irritation is often complicated with hysteria, generally with uterine derangement, still we not unfrequently meet with it as so well pronounced an individuality as to be unmistakeable and SRomberg, vol. i, p. 155. THE NERVOUS CENTRES. 501 aggravated by pressure. This morbid condition was not derived from the uterus, the functions of which were unimpaired, nor from any other viscus. It was an idiopathic affection of the cord; and what Dr. Romberg would have called it I don't know; but for all practical purposes the term " spinal irritation " is good enough. It is true, had the patient died a post-mortem examination would have revealed as little as in the case reported by Abercrombie, already quoted; but he did not on that account hesitate to refer the symptoms to some morbid change in the spinal cord, although he was unable to discern any such change. We are equally entitled to affirm the existence of a disease of the cord in this instance, although we cannot form any conjecture even what the precise nature of that change is. There was no opportunity in this patient for such a scrutiny as Romberg requires, for under the use of Arnica, Belladonna, Naja, and Sulphur, she got quite well in about eight months, and when I last heard of her, she was in the enjoyment of so much health and strength as to be able to nurse an invalid sister. In cases like this one, of pure spinal irritation, I have great confidence in Arnica, Belladonna, and Naja. Although the severity of the pain, and general sensitiveness of the system seems to indicate excess of vitality, at least of nervous irritability, yet the experiments of Brown-Sequard rather point to an opposite conclusion. He found that a transverse section of the posterior columns of the spinal cord, instead of destroying or diminishing sensibility, was followed by a notable increase of sensibility of almost all the parts of the body behind or below the section.7 1 ' Medical Times and Gazette,' April 26th, 1856. 502 SOME LESIONS OF We frequently meet with another variety of spinal irritation where there is also great pain, but not attended with the languor and general hyperzesthesia; rather a sort of neuralgia of the spine. For this I have found Veratrum very useful. I look upon the distinction of the varieties of spinal irritation as very important, as probably the dissimilarity of the sets of symptoms depends upon some radical difference in the morbid change in the spinal cord. Neuralgic affections, although sometimes associated with spinal irritation, are a class of themselves; and Romberg observes that " Vaillez and others have made valuable contributions to our knowledge of cervical and intercostal neuralgia, and that alone has withdrawn a large class of affections from the sphere of spinal irritation, which its advocates are peculiarly fond of appropriating." The following case of intercostal neuralgia affords a good illustration of its entire dissimilarity from spinal irritation. A woman of 50 years of age, consulted me, on the 8th of November, 1854. She stated that for ten years she had suffered constant severe pain in the chest under the left mamma. For the last two months it had been very violent. She had vomited blood. The affected side felt either too cold or too hot, generally the latter. The appetite was good and the digestion healthy. She got Ranunculus bulbosus, and came back in a week to report herself better. The same medicine was continued with good effect, and, along with a few doses of Nux vomica, entirely removed the pain. There remains for our consideration the third class, THE NERVOUS CENTRES. 503 which we have called sympathetic spinal irritation. The term is objectionable, but may answer provisionally, to distinguish all those affections of the spinal cord which depend upon excessive or irregular action in the other organs, from those which have their origin in the cord itself. The first peculiarity that strikes one about this last class is, that it is almost exclusively confined to the female sex. The pains in the back which we meet with in men are chiefly rheumatic, unless they be from kidney disease, and they are comparatively rare. Among women they are almost universal, and differ chiefly in degree. The reason of this is manifestly the heavy periodic demands upon the centre of the nervous system to enable the catamenial discharge to take place. This regularly recurring effort at reproduction is attended with more or less of excitement and exhaustion. It involves in a slight degree what its completion, so to speak, conception and parturition, involve to a very great amount, a sacrifice of the individual vitality to the maintenance of the race. This is Nature's interdict against the insane attempts to assimilate the sexes in regard to their work. A woman for some thirty years of her life is subject to a periodic weakness, which should be more or less indulged by a certain degree of repose from toil, otherwise her constitution suffers. This is probably the reason why needlewomen come in such crouds to consult us for pain and weakness of the back; while, for my part, I do not remember to have had a single shoemaker or male tailor suffering from this cause. Now, although needlewomen may sit somewhat longer than shoemakers, still the lonig twelve hours' seat of the shoemaker would undoubtedly break down a great number of women. THE NERVOUS CENTRES. 505 In this instance there can be little doubt that the mother's life was thus compromised for the sake of her offspring, and that if, instead of having had eight, she had had only three children in the thirteen years, she would now be alive and well. Such cases prove the heavy draught upon the spinal cord of the process of uterogestation and parturition; and it seems to. me that they stand in opposition to an axiom of Dr. Marshall Hall, that involuntary reflex actions are not attended with exhaustion of the spinal cord, and that this organ does not require for itself the refreshment of sleep. In proof of this view, Dr. M. Hall refers to the long flight of certain birds, which he believes to be carried on without any wear and tear of the nervous functions, by their reflex action alone. But are not all the relations of the uterus and other genital organs to the spinal cord of the reflex character, that is independent of volition? Yet, as we see, there is nothing which so exhausts the nervous system. The whole subject of the relation of the spinal cord to the organs of secretion and involuntary muscular action is one of great difficulty, and we must wait for fresh light from the researches of physiologists. In the mean time, although we occasionally meet with a disheartening case such as the one I have just referred to, yet it is consoling to observe that the large majority of cases of sympathetic spinal irritation, whether those depending upon exhaustion of the spine or of transferred irritation from irregular action, are remarkably under the control of homoeopathy. For example: A woman, 45 years of age, consulted 506 SOME LESIONS OF THE NERVOUS CENTRES. me, on the 11 th of February, 1857, and thus stated her case. The catamenia had ceased the previous August, and from that time she had never been free of pain in one side of the head, coming on in paroxysms of great severity. She is also daily subject to pain in the right arm, which, when it comes on, causes contraction of the muscles, and makes the arm quite useless; the muscles of the orbit are also affected, and the eyeball misdirected. There is little appetite, but in other respects she is in good health. I gave her the 3d dilution of Naja, a dose three times a day for a week. She returned at the expiration of that period and reported that she had not been so free from pain for three months. She could use her hand and arm to cut her meat, which she had not done for that length of time. The niedicine was continued, and in another week she reported herself as free of all pain, except in the back. This pain in the back remained, notwithstanding various medicines, for three months, when, after a course of Sepia, the catamenia reappeared, and she got well-at least, she ceased to come, and I have every reason to presume she was and. is well. The case is curious as illustrating the transference of an irritation of the spinal cord, produced by want of uterine action, to the nerves of the head and the muscles of the arm, its return to the spinal cord, and eventual cure by the restoration of the function. 507 ON EPILEPSY. There are few diseases, if any, more interesting to the practitioner, and especially to the homoeopathist, than epilepsy. It is one of very frequent occurrence: out of 3636 patients treated at the London Homceopathic Hospital, 191 were epileptic. It is one not less mysterious in its nature than uncertain. For example, we find that out of the 191 cases which were treated at the London Homceopathic Hospital, 38 were reported as cured; out of 16 cases treated at the Leipzig Dispensary in 1854, 6 were cured; while at the same institution during the following year, out of 10 cases there was only one cure.1 Out of 51 cases treated at the Hahnemann Hospital there are no cures recorded, nor of the 3 cases reported as having occurred in the Manchester Hospital. This enormous diversity of result suggests a corresponding difference in the character of the cases, for the treatment was doubtless much the same in all, and, indeed, the results of two years in the same institution present almost as great a contrast as we meet with in the series. On what, then, does this difference depend? This question implies a previous one. What is epilepsy? It is briefly described by Dr. Watson as " a temporary suspension of consciousness with clonic spasm, recurring at intervals."' If we accept this definition, we exclude from the title of epilepsy all cases of 1 ' -om. Vierteljahrschrift,' 185-1-55. 2 'Lectures on the Principles and Practice of Phyic,' by Thomas Watson, M.D., third edition, vol. i, p. 621. 508 EPILEPSY. convulsions which consist of one single attack, and this is by no means an inconsiderable class. For example, many children have what is called a teething-fit, and in most treatises on the subject such fits are represented as being of a true epileptic character. The same may be said of the fits which not unusually attend intestinal irritation and child-bearing. In short, this definition limits the use of the term to cases where the disease presents itself as one of a periodic kind, and suggests the suspicion of its origin being in the centre of the nervous system, the brain or spinal cord, and not in any irritation of the peripheral nerves. Perhaps this is the juster view to take, but it is opposed to the uniform practice of all writers from Hippocrates downwards, not excluding Dr. Watson himself, who in this matter falls into a self-contradiction. That epileptic attacks begin, in some cases, by an irritation at the circumference, is an indisputable fact. Romberg' relates the following case, which came under his own observation, in proof of this. " A labouring man of robust constitution, who applied for relief in the Policlinique, had fallen, three years previously, upon his right knee, in consequence of which the joint had become disorganized. The patient had from this period suffered from epileptic attacks. The aura epileptica commenced as a creeping sensation in the large toe of the right foot; from here it mounted upwards along the inner surface of the leg and thigh, and ended in the epileptic seizure. In this case the aura did not proceed from the seat of the injury, the knee-joint; 1 ' Diseases of the Nervous System,' vol. ii, p. 210. EPILEPSY. 509 but when we consider the sensibility of the integuments at the inner side of the knee-joint, as well as those of the large toe, is derived from the same nerve, the saphenus major, the connection between the aura and the cause of disease seems undeniable." This is a very instructive case, for it seems to prove two things: first, that epileptic convulsions may really be caused by some injury to the peripheral nerves, and this is confirmed by many similar cases on record; and, secondly, that the aura which is referred by patients to the extremity of the nerves, may be caused by some morbid action at some point nearer the centre. In Romberg's patient the knee was the " fons mali," but when there is no obvious injury, it is impossible to tell whether this curious sensation be really of central or peripheral origin. The whole subject of this aura epileptica seems to require further observation. It has been probably too hastily adopted as a pretty constant feature in epilepsy upon conjectural grounds. That an impression made at the surface should be conducted like an electric current up the nerves till it reached the brain, where it exploded the accumulated nervous irritability, and produced a convulsion, seems a sort of notion tacitly conveyed, both by popular and medical writings. And yet when we investigate this mysterious aura, we find that its very existence as a precursor of epilepsy is denied by some of the best observers, while its explanation, on the other hand, is probably quite different from that commonly received. Dr. Pritchard,' a very accurate writer, says of this so-called " aura:" " This symptom is usually termed by medical authors.the aura ' On Diseases of the Nervous System,' p. 88. 510 EPILEPSY. epileptica, and it is described by them as a sensation of a cold vapour affecting the part and rising upwards. I have met with a great number of patients who have perceived the affection alluded to, but I never once heard it described in this way, though I have been very minute in my inquiries. It is generally represented as a convulsive tremor commencing in a limb." Although Dr. Pritchard rejects the term aura, yet he fully concurs with other observers that some peripheral agitation precedes the fit. The question that next occurs is, whether these muscular tremors arise from an irritation propagated from the brain and forewarning the attack, like the rustle of the leaves before the tree is bent and shaken by the tempest, or whether this symptom is the first link in the series of actions, which, if repressed, would terminate the whole. In certain instances, the latter inference seems the just one. " Sometimes," says Dr. Pritchard, " there is even a perceptible convulsion of the large muscles of the limb, as in the case to be adduced below, in which the patient averred, that by grasping firmly the muscles of the leg in which the agitation began, she could prevent the attack of coma." There may indeed be a doubt whether the cause of the arrest, supposing the woman's statement be true, may not have been owing to a powerful effort of volition acting consciously towards the leg, and unconsciously towards the brain; for, in a case related by Dr. Seymour, an epileptic boy was in the habit of arresting a paroxysm by biting his tongue. We may safely conclude that if the so-called aura ever do arise from the circumference, it is at best a very rare occurrence. There is no doubt, that in the vast majority of in EPILEPSY. 511 stances, the perturbation of sensibility at the extremities of the nerves is from a morbid action at their origin, vwhich, on its transmission along the branches, produces at the same time a muscular convulsion and a peculiar sensation. And it is certainly most unaccountable, that if this excitement be prevented from reascending to its original point of departure, the fit is sometimes cut short. A case of this kind is recorded by Odier,1 of a soldier, who, in consequence of a sabre-cut across the left side of the head, became subject to convulsions, which always began in the little finger of the right hand, and gradually extending up the arm to the shoulder, ended in a true epileptic seizure; he found the epileptic attacks prevented by tying a cord tightly round the arm in two places. By this simple expedient he staved them off for three years, but, mLfortunately, being attacked on one occasion when intoxicated, he was unable to employ his accustomed preventive, and a fit came on which ended fatally. The post-mzortemn examination disclosed a tumour on the surface of the brain, connected with a depressed lamella of bone, where the wound had been received. Had the history of this case not been so fully known, it is one which might naturally have been cited as an example of epilepsy commencing at the circumference, from its first manifestations being there, and from its being cut short by the arrest of the peripheral agitation. This teaches us caution how we accept such explanation in cases where the state of the brain is not ascertained. Romberg mentions a very curious fact, on the autho '1 Medecine Pratique,' p. 181. 512 EPILEPSY. rity of Dr. Sch6nbein, " that in several patients who were blistered, he observed that immediately before the fit the serum assumed an acrid character, as in Humboldt's galvanic experiment." The inference Romberg draws from this is, that as yet we have not paid sufficient attention to the changes induced in the sphere of nutrition by that disordered condition of the nervous system on which epilepsy depends. This seems a very important remark, and one which has a directly practical bearing, for if the derangement of the digestive organs be the consequence and not the cause of the epileptic condition, it is pretty evident that the remedies suitable to cure gastro-intestinal irritation of an idiopathic kind may have little effect in correcting the morbid state of the nervous system on which epileptic dyspepsia, if such a term may be used, must be supposed to depend; and that a practitioner who follows a superficial symptomatic course of treatment, instead of a deeper pathological one, will probably be disappointed in its results. For example, in Dr. Laurie's '.Practice of Physic,' almost the only systematic work we have upon our therapeutic principle, we find the following headings, each succeeded by an enumeration of its appropriate remedies. Epilepsy "from plethora, with determination of blood to the head;" " from debility, caused by loss of hiumours," "from the irritation of worms," " from teething," " from hysterical affections," "from the retropulsion of an eruption," "from the abuse of intoxicating drinks or narcotics," "from Mercury," "from checked perspiration," " from exposure to the fumes of Arsenic and copper," "from moral causes, such as fear, &c.," "from crudities of the stomach," and " from an injury of the head." Under EPILEPSY. 513 every one of these headings we find Nux vomica, and in the following page we have the special indications of Nux v. thus recorded: " Shrieks; throwing back of the head; trembling or convulsive jerks of the limbs or muscles; renewal of the fits after contradiction or an angry emotion; unnoticed evacuation of faeces and urine; sensation of torpor and znubness in the limbs; vomiting; profuse perspiration; constipation; ill humour and irascibility between the attacks." Now it is quite true that these symptoms are common to Nux v. and to epilepsy, but a moment's observation will satisfy anyone that there exists a cardinal distinction between the effects of Nux v. and the pathological cause of epilepsy, and this is, that Nux v. is confined in its sphere of action to the spinal cord, whereas epilepsy depends upon some affection of the brain. A morbid action at the highest point involves all the lower parts, and produces symptoms common to all cases where they are affected; but a remedy to do good must reach the height of the source, and in this instance, be able to induce unconsciousness, otherwise it is inconceivable it should be of any use. " The weakest convulsion," says Hufeland, "with unconsciousness, is epilepsy; the most violent convulsions, consciousness existing, are not epileptic."' A stream from a poisoned fountain cannot be purified by any chemical works half way down its course. It is not with the object of captious criticism that this quotation is given, it is simply in illustration of a prevailing practice, peculiar to no school, of being led away in the treatment of this and similar diseases from what seems the only true road ' Enchiridion Medicum,' p. 210. 33 514 EPILEPSY. to cure- the application of a remedy to the seat of a disease. Although beyond all doubt epilepsy depends in almost all instances upon some morbid condition of the brain, yet what that condition is has not yet been ascertained. That organic alteration of some part of the brain is a very frequent attendant upon epilepsy has been amply demonstrated; but all attempts to determine the special part of the brain have hitherto failed. J. Wenzel ascribed it to changes in the pituitary body along with a morbid state of its surrounding bony cavity; but the researches of Engel and others have entirely failed to confirm this opinion, which, however, rested upon a series of careful dissections. Indeed, there seems ground for believing, that, even where organic changes in the brain are manifest after death, they may be the consequence, and not the cause of the disease: for we know, as a certain fact, that true epilepsy is suddenly produced by what may be called essentially functional causes. For example, Maisonneuve relates two cases of confirmed epilepsy being produced by gazing at the sun. The one was that of a girl of five years old, who amused herself one summer day by looking for some minutes at the sun, and was immediately attacked with epilepsy, to which she remained subject for nine years; the other, after having gazed at the sun in the same way, was alarmed at seeing a large black head, and in the evening she too was attacked by epileptic convulsions, which returned at tolerably regular intervals. Pritchard mentions a case produced in a woman by witnessing an execution. Now, in such instances, and they might easily be multiplied, there seems great improbability that there should take EPILEPSY. 515 place a sudden organic change in the brain. And it is very remarkable that even in cases where the patient had suffered from the severest forms of epilepsy for many years, no perceptible cerebral lesion has been discovered after death. As this point is very important, and the statement is rather opposed to the testimony of many high authorities, it may be worth while to quote the following striking illustration of it from Dr. Graves." Mr. A. B., the subject of the following case, was visited during his long illness by a great many medical men, among the rest by Mr.. Colles, Sir P. Crampton, Mr. Singly, Dr. C. Lees, and myself. He died on the 27th of December, 1839, aged 30 years. He had been a very fine, robust, and intelligent boy until he was nine years old, when he unfortunately got hold of five or six hard, unripe pears, and devoured them greedily; in a few hours he became thirsty, and drank a large quantity of buttermilk; in the course of the evening he fell into a state of insensibility, during which he was convulsed. A physician of great experience and judgment from Kilkenny was called inl, who opened the temporal artery immediately on seeing the patient, and employed the usual means resorted to on such occasions. Notwithstanding this, the insensibility continued, and in about seven hours it was observed that a hard tumour could be distinctly felt in the epigastric region. This induced the suspicion of some undigested substance, and a strong purgative enema was given; its effect was satisfactory,-after a copious evacuation, the tumour disappeared, and the boy recovered his senses. From that time, however, he be 1 ' Clinical Lectures,' p. 489. 516 EPILEPSY. came subject to epileptic attacks. They annually became more frequent and severe, and after six years the intellect began to be impaired, and gradually lapsed into almost total idiotcy. He now remained almost entirely in the house, and for many years had several epileptic fits daily; the convulsive stage did not usually last more than three or four minutes, but the coma often continued nearly an hour. The disorder generally exhibited a manifestly increased severity twice a year, when the fits would return about ten times daily, and with more than ordinary violence; after such a paroxysm had lasted about a week, it invariably terminated in outrageous madness, the appearance of which was a sure sign that the paroxysm, so far as the fits were concerned, was over; this madness was of the most violent and noisy description, and required restraint; when it had subsided, which it usually did in about three days, he relapsed into his ordinary state, with a few and comparatively slight fits daily. Such was the course of the disease for sixteen years, during which he was most tenderly and assiduously nursed. I ought to have mentioned that a sudden and copious bleeding fr-om the nose often took place when the fits came on; the breathing was invariably violent, irregular and heaving, for eight or ten minutes after the convulsion had ceased, but then gradually became tranquil, and so continued for the remainder of the comatose stage. During the last five years of this gentleman's life the fits became gradually less violent, but never ceased; for several years before his death he remained free from attacks of madness. The post mortem examination was conducted under the most favorable circumstances by Very skilful and experienced anatomists. The result, so far as the EPILEPSY. 517 head was concerned, was that the scalp, cranium, dura mater, arachnoid, pia mater, together with the cortical and medullary substance of both the cerebrum and cerebellum were all perfectly healthy; a very small quantity of transparent serum was found in the ventricles; there was no notable subarachnoid effusion; the spinal marrow and its investments were quite normal." The farther details of this case would be foreign to our present purpose, but we may adduce Dr. Graves's concluding observation, that he had known a gentleman who for nearly thirty years was subject to frequent attacks of epilepsy, and who yet was quite free from the disease for the last twenty-five years of his life. Such facts, although they can hardly be said to warrant our holding out to epileptic patients a prospect of cure if the disease has lasted a long time, should at least prevent our condemning any to utter hopelessness. In our ignorance of the proximate cause of epilepsy, it is natural that we should direct our attention in a more special degree to the exciting causes, as they sometimes afford important indications for treatment, and among these the repulsion of old eruptions undoubtedly deserves a place. Hahnemann, in his introduction to his work on " Chronic Diseases,' has collected a good many examples of this effect of the sudden cure of cutaneous diseases; and Dr. Pritchard states that attacks of epilepsy are by no means rare as consequences of the disappearance of the chronic or non-febrile disorders of the skin. Dr. Ferriar has mentioned the case of a gentleman who became subject to epileptic fits in consequence of the disappearance of scabies after the use of some external application, and who was suddenly cured of them, after 518 EPILEPSY. a variety of remedies had been tried, by reproduction of itch.' It is refreshing to meet with such confirmation of the statements of Hahnemann in the works of his opponents, and it may induce us to give more weight to his opinions in regard to psora than at present it seems the fashion to do. Among the predisposing causes there is none to compare in importance with hereditary influences. It appears from statistical inquiries made by Cazauvieilh and Bouchet, that out of 110 epileptic patients there were 31, or nearly one third, who had epileptic parents or relations; and that 14 epileptic mothers gave birth to 58 children, of whom 37 had died, the eldest at the age of 14, the remainder at a very early age, and almost all in convulsions. These facts should be borne in mind if we are consulted as to the propriety of a person subject to epilepsy contracting a marriage. When we consider the danger, not only of transmitting epilepsy, but of engendering insanity by such a wedlock, it may raise the question as to whether there should not be a legal bar to marriages fraught with such certain and serious danger to the community. For it is not merely the chance epileptics, or lunatics, so to speak, that are the mischief, but it is the infusion of bad blood, every drop of which does harm, and retards the elevation of the race. The age at which epilepsy is most likely to occur has been carefully investigated. Out of 66 cases compared by Cazauvieilh, 50 occurred before the 20th year of the patient's age; of the remaining 16, 5 began before the 25th year, and only 1 after the 50th. It is generally 1 Op. cit., p. 218. EPILEPSY. 519 believed that epilepsy never begins after 50 years of age: there ate, however, cases on record where it made its first appearance in a man in his 69th year, and in a woman in her 72d. How far the age at which it appears modifies the chance of recovery or cure is not so easily decided. Dr. Laurie says "when the disease occurs before the age ofpuberty, or when purely sympathetic, it is generally curable without much difficulty by means of homoeopathic remedies."' If this statement is really the result of, observation and experience, it is extremely encouraging, for nearly half of all epileptic cases commence at this favorable period. Without questioning that the amount of individual success may have warranted this opinion, one cannot help fearing that it rests upon too insufficient data to be accepted as a general proposition. Pritchard, a most accurate observer, says, "epilepsy often appears for the first time about the eighth or from that to the twelfth year; and it is under these circumstances that the greatest danger exists of its becoming an habitual disease. There is still a prospect of its subsiding in males at the age of puberty, and in females at the establishment of the catamenia; but if these periods pass over and the disease subsists through the changes which the habits of the constitution then undergoes, there is great danger of its continuing through life. But if the appearance of the catamenia sometimes assists the constitution to get rid of this disorder, it much more frequently gives rise to it; or, rather, the laws of the animal economy require a new set of operations to be set up in the system at this time, in the place of which, when they are I Op. cit., p. 355. 520 EPILEPSY. not regularly performed, a variety of tumultuous efforts ensue, and among phenomena of this class none is more frequent than epilepsy. In fact there is no time of life in females at which it so frequently makes its appearance." 1 Perhaps if Dr. Pritchard had practised homceopathy, he might have changed his opinion as to the great risk of epilepsy in the young becoming permanent; or it may be that if Dr. Laurie had had the same amount of experience as Dr. Pritchard, he would have qualified his statement. As far as my own observation goes, it is opposed to that of Dr. Laurie; for certainly by far the worst cases of epilepsy that I ever met with have been in boys under twelve years of age. It would, however, be wrong to make an inference from this, as the number of cases is too few; and when we consider the great power of our medication in regulating and tranquillising the system during the period of puberty, and how rapidly hysterical and spasmodic affections frequently yield to the influence of homceopathic remedies, it may not be unreasonable to expect that those forms of epilepsy which are excited by the purtubations spoken of by Dr. Pritchard may be averted, if "the tumultuous efforts " are calmed and the stormy latitude passed over under favorable circum.; stances. For the more we examine the subject, the more clear it appears, that epilepsy depends upon two concurrent causes; the one, a permanent morbid condition of the brain, which gives a tendency to the production of unconsciousness and convulsions, making epilepsy possible; the other, some exciting cause within or without SOp. cit., p. 95. 522 EPILEPSY. a bad sign, for it shows that the brain must be the origin of the attack, as all external excitements are at that time absent. It certainly does prove this; but the inference of such cases being at all worse than those which take place in the day-time does not seem to be confirmed by the observation of their course, which, after all, is the only sure test of the comparative severity of the two classes. And we know too little about sleep to form even the remotest conjecture of the nature of its positive effect upon the cerebral function. We are obliged to recognise merely its negative aspect-the attendant unconsciousness; but we cannot penetrate this shroud, which conceals its phenomena as well from the cognizance of the sleeper as from the investigations of the spectators. We receive only obscure hints of an active sleeping mental state through dreams, and by the morbid disturbances to which it is subject. Of these, one of the most remarkable is somnambulism, and this condition is a frequent occurrence with persons subject to epilepsy. Indeed, the relations between sleep and epilepsy seems to be of a very radical character, and not merely accidental. It is powerfully affected by mesmerism; and there is a minor degree of the epileptic state which bears a close resemblance to that kind of imperfect artificial somnambulism known by the absurd name of electro-biology. I have recently treated a female epileptic patient, who presented a singular example of these milder attacks, called by French writers lepetit eval, interposed between the more severe one of le grand vnal. She was subject to fits of falling down in unconsciousness, attended with convulsions; but besides these, shc would suddenly appear in a sort of EPILEPSY. 523 vacant condition, in which she walked about, although with an unsteady gait, and answered questions coherently, but she had no recollection of what had passed in the period. She once had one of these attacks in my house: she was sitting in the waiting-room, and when there dropped a piece of money; when she came into the room where I was she looked like a person walking in sleep, but she sat down and replied to my questions; she gradually seemed to recover full consciousness, and then felt uneasily for her money; on opening her purse, she said she was sure she had dropped some, for the last thing she recollected was taking it out whilst sitting in the adjoining apartment, and that there was now less in her purse than there should have been. Of what passed between the time of her taking her purse out and the moment she became conscious of her loss (which turned out to be real) she had not the slightest remembrance, and yet she had behaved in such a way that I had not the least idea she was unconscious. It was, in fact, a brief attack of somnambulism. In some way or other epilepsy is allied to sleep; and it might almost be said, without an exaggeration, to be a disease of sleep, for a large majority of attacks take place in sleep, and it is therefore no wonder that we cannot comprehend the morbid changes of a condition which in its most normal phenomena is an impenetrable mystery. It may be from this relation to sleep, the great periodic phenomenon of all sentient life, that the periodicity of epilepsy is derived, or perhaps both are in some way or other connected with the alternations of the cosmical influences to which all the inhabitants of our revolving abode are subject. That epilepsy is affected in some EPILEPSY. 525 the remainder is of the saddest character. Death occasionally occurs, but much more frequently the victim of " this possession," as it used to be considered, continues to live on, but gradually loses his intellect, and generally ends by becoming insane or idiotic. To this rule there are, however, a sufficient number of exceptions to warrant us in encouraging our patients with the hope that the attacks may not affect the mind. Cheyne 1 says he has known individuals subject to epilepsy preserve their intellect unimpaired in old age. "A very dear friend," he adds, "who was liable to epilepsy, died a few months ago in the seventy-fourth year of his age, whose comprehensive, well stored and active mind, remained unclouded till within a few weeks of his death." Among the examples usually adduced to illustrate the continuance of perfect sanity along with epilepsy, are Julius Caesar, Mahomet, and the great Napoleon. Cwesar was not affected with this disease till near the close of his life, and whether he displayed any change of temper and intelligence that might have ripened into mental weakness, is, perhaps, not known to scholars. But that Mahomet was subject to epilepsy is a singular fact in reference to his psychological character, and may account for some of his ecstacies and supposed revelations; and, perhaps, the infatuation of the great Napoleon, towards the latter part of his career, may be in some slight degree accounted for by an incipient disease of the brain, which would have developed itself in that organ, had it not taken another form when enforced rest transferred to the lower organs the activity natural to the higher. For ' Cyclop. of Pract. Med.,' art. " Epilepsy." EPILEPSY. 527 observation: but what is to be done? Are we to wait till we discover medicineswhich produce epilepsy? It is rather disheartening to observe that one of the few substances known to have this effect is comparatively seldom given for the cure of disease by homceopathists. "Among the older writers," says ]Romberg, " Stoll has already pointed out that epilepsy is the result of lead-poisonin1/; among moderns, Laennec and Andral have drawn attention to the fact, but the subject has been most comprehensively treated by Tanquerel des Planches, who has observed thirty-seven cases himself." Doubtless, we may hope that future investigations may enable us to apply to more effect our law of cure in these cases, but in the mean time as the reviewer truly observes, we are compelled to submit to a more empirical method, and to be guided more by our clinical experience than by our study of the Materia Medica pura. While admitting that this is an imperfect, and while hoping it is only a temporary plan, yet in the immediate urgency of practice it is one we are compelled to adopt, and it is well we should make the best of it. To do so it is essential that we should have a clear notion of what are the important points to register in reference to the attacks. Of these, the age of the patient, the period of the day or night when the attack occurs, the duration of the unconsciousness, and the subsequent effect of a fit upon the memory, are all of cardinal importance, while, on the other hand, the peculiar cry, the way in which the fingers or thumbs are drawn, or the eyes roll, are really of no consequence whatever: and yet it will be found that the indications in Jahr and Laurie have more reference to the useless and accidental individual adversities than to the funda 528 EPILEPSY. mental distinctions. In fact, the way in which these indications have been arrived at is radically false. A case of epilepsy is reported in full, that is to say, the exact character of the fits, whether there was grinding of the teeth, clenching of the hands, wildness of the eyes, &c., and it is also recorded that Cuprum had been given and the fits subsided. Straightway, the book-compilers extract the symptoms as described, and publish to their credulous readers that in the event of their meeting with a case in which there is grinding of the teeth, clenching of the hands, &c., they are to. give Cuprum! It does not seem to occur to our teachers that the indications they record as discriminative are really common to almost all convulsions, and while they dwell upon the common they omit the peculiar. It is not enough in drawing up a " hue and cry" to describe the thief as a biped, without feathers, or even supposing the document published in England that he presented the most undoubted features of being of the Caucasian type, in fact he might be summarily described as looking like an Englishman. It is not a bit more to the purpose when we ask in what cases of epilepsywe are to give Belladonna, and in what Cuprum, to tell us that the former is of use when there is a " sensation of crawling and torpor in the upper extremities," the latter when the paroxysm begins " in the fingers or toes, or in the arms." 1 It must be admitted, however, that it is much easier to say " how not to do it" than how to do it, and the utmost we can hope for at present is, that each practitioner will record simply the result of his experience in epilepsy, and state fully the history of 1 Laurie, p. 356. EPILEPSY. 529 his cases, and in this we may gradually methodize our treatment, and if we do not rise to the height of being guided by a sure law, at least have the satisfaction of following a rational empirical rule. I am well aware that the following cases are very defective in the requisite details, but they were never meant for publication, and they are now given with the hope of calling forth from others their experience in this common and dreadful malady. CASE I.-G. A-, a well-grown and intelligent lad, seventeen years old, had his first epileptic attack at fourteen years of age, that is three years ago. About three months after had two fits: he was free from them for four months, after which period they returned, and ever since that has had one or two at intervals of three or four months. I saw him first on the 24th of August, 1855, and he had had six attacks the previous day, and one that morning. The fits begin with convulsions of the muscles of the face, which extend to the arms and legs. He is generally unconscious for twenty minutes. He got the second dilution of Belladonna, and was to be taken three times a day. He continued this medicine, repeated from week to week, and had no attack till the 11th of January, whei he had one fit at night. This was a longer interval than had yet elapsed since the first fit, and there was only one fit this time, so Belladonna was continued up to the 14th of July, when he got Mercurius for a cold, and up to the present time he has been quite well. I consider that he is cured, and by Belladonna. This medicine, it will be observed, he took daily for nearly eleven months, and as the fits first made 34 EPILEPSY. 531 a fright, and soon afterwards had one epileptic fit. The fits have continued ever since; they always precede and follow the catamenial period, and generally last for a quarter of an hour; she is stupefied for a time after the convulsions are over, and for some time back her memory has been weakening. She has a sensation of " something in her left side," but no regular aura as a precursor of the fit. The catamenia are regular and too copious; she is subject to relaxation of bowels after an attack. She got the 2d dilution of Belladonna, to be taken three times a day for a week. She returned on the 17th of September, and said she had had one attack during the interval. Althoughher epilectic attacks have come on invariably for the last twenty years at the catamenial period, yet she has them frequently at other times, and without any observable periodicity. The Belladonna was continued till the 19th of November; she then reported that the last period had passed without a fit, but there was an abortive attempt at one, consisting in what she called " a shuddering," a sort of general tremor with a peculiar sensation. The Belladonna was continued. On the 19th of December she returned and reported having had one very slight fit the previous week. She again got Belladonna. On the 31st of December she complained of excessive depression of spirits, and got Naja; on the 7th of January she got Carb. veg.; on the 14th, Ignatia; on the 11th of February she reported that the catamenia had not appeared at their usual time, and she got Sepia. On the 25th, she complained of weakness, trembling, and depression, and again got Ignatia till the 31st of March. She stated that during the interval she had only had one very slight fit, and up 532 EPILEPSY. to the end of May she had continued free from them. Having discontinued her attendance, I do not know the final result. This case is not so satisfactory as the previous one, still, that attacks which for thirty years had occurred with the most accurate punctuality every month, should be so rapidly modified in their character after the administration of homoeopathic medicines, is a striking fact in itself. CASE IV.-M. P-, a big lad, 19 years of age, of a very dull expression of face, and an almost idiotic gait and demeanour, was brought to me on the 6th of March, 1856. He had been suffering from epilepsy for six years. The fits occurred two or three times a day, but not every day. He got Belladonna 2d dilution, a dose to be taken three times a day. He returned on the 2d of April, and his mother reported that he had had two bad fits the last week. The medicine was continued. From that time to the 14th of May he remained free of all attacks; on that day he had one fit. He had nothing but Belladonna up to the 23d of July, and his mother affirms very confidently that his mind is improved, he is more intelligent, and that the fits are far less frequent and severe. He is still under treatment. The improvement in this case is remarkable, for the patient presented the worst appearance, having the heavy vacant look peculiar to old epileptics. CASE V.-E. M-, a young woman 21 years of age, came to see me upon the 4th of December, 1853. She had been subject to epileptic fits for ten years. The convulsions affected only one side of the body, which was EPILEPSY. 533 represented to become black; they were said to be very violent, and attended with complete unconsciousness; they returned every two or three weeks. She had never passed more than five weeks without a fit since her first attack, which took place when she was eleven years old. She was subject to violent pain at the top of her head, otherwise her health was good. She got the 3d dilution of Cuprum, a dose of it three times a day, and returned on the 25th of January to state that she had had convulsive jerkings and tremors of the hand and arm, but no fit. She got the 2d dilution of Belladonna to be taken in the same way. February 1st, the report is, " not so well; " complains of pain in side and head, especially at the vertex. Cocculus, 2d dil., as before. February 11th, jerking of arm and leg, but no fit for nine weeks. Repeat the Cocculus. March 1st, no fits. Repeat. March 8th, had jerking in hands and arm, but no fit. Repeat Cocculus. March 21st, no fits, and jerking better. April 12th, no fits; more jerking of arm. Cuprum, 3d dilution. September 11th; she returned this day, and stated that for nine months she had been quite free from fits and tremors, but they had returned the previous week. She again got Cuprum, and on the 18th, reported that she had had another fit, and again another occurred on the 25th, when she got Belladonna, 2d dilution. She remained free till the end of a month, when she had a fit, and got Cocculus. She returned on the 20th of November, and stated that she had had three fits the previous week; she complained of sore throat, and got Belladonna. From this time to the middle of January, 1854, she remained free from fits, and then discontinued her attendance. This case illustrates the inse 534 EPILEPSY. curity of apparent cures, and the capricious character of the malady. For ten years she never passed five weeks without at least one fit; after a little less than four months' treatment she passed nine months in perfect health, and one might have supposed the disease cured, and yet it was only alleviated, the exciting cause was probably removed, but not the morbid condition of the brain; so it returned again with considerable severity. CASE VI.-L. P-, aged 14, a pale girl, healthy looking, four years ago had her first epileptic fit. It was very bad; there was no cause assigned for it. They have returned at irregular intervals until a year ago, when they began to occur once a month. They last for a quarter of an hour, and go off in a sleep. She had one three weeks ago, and considered one was nearly due when she applied to me, on the 20th of March, 1857. She got the 2d dilution of Belladonna, and had no fit till the 22d of June, and none between that and the 12th of November. These are all the cases of sufficient general interest, as illustrating either the action of particular medicines, or the character of the disease, that I find worth reporting, and I may conclude with this observation, that on the whole I have more confidence in Belladonna than in any other medicine, in ordinary cases of true epilepsy, and I think it is of consequence to continue its administration for a long time after the fits have ceased. I have often given it in the 2d dilution, for months, and I never saw the slightest harm from it. EPILEPSY.55 535 The following case, although not one of epilepsy, is so far allied that it may -not be out of place here: The-subject of it, W. F'-~-, was a fine hearty-looking man, 49 years of age, a gardener, who had been in the enjoyment of good health till three years before, when he fell from a height of thirty feet upon the top of his head, a~nd was after that unconscious for -five weeks. Ever since that time he suffered constant pain at the vertex, attended with such extreme mental dejection, that he has been unfit for work, and would sit and weep the whole day long. He complains of constant thirst, and no appetite; the ton-gue was coated, and the bowels torpid. I saw him first on the 19th of December, and he then got Nux, v., 2d dilution. He returned on the 3 1 st, and said his appetite and bowels were better. He then got Sulphuric acid, 3d dilution, a drop three times a day. From that time he began to improve rapidly; the pain in the head went off, his spirits returned, and in the course of a month he was able to go to work, and on the 10Oth of April he sent me -a message that he was perfectly well, and at his work ' as before his accident. CHAPTER X. ON MESMERISM. IT is impossible for any sane mind to be brought in contact with the world of mesmierism without being dismayed- at the dismal disorder which reigns over the whole region; one feels as if quitting the familiar earth for Tartarus, and exchanging the diffused light of day by which we recognise the colour, form, and distance of objects, for the fitful corruscations of the aurora borealis or gleams of vivid lightning, that dazzle the sight rather than reveal the things around us. We feel that all our conscious experience is opposed to the phenomena we seem to witness or of which we are told; and while we dare -not refuse the evidence of our senses or the testimony of trustworthy witnesses, we are equally unwilling to receive as truths appearances or statements utterly- at variance with all probability. A little reflection, however, will convince us that this discrepancy is apparent rather than real. The experience by which we try mesmeric phenomena is all derived from our waking state. Mesmerism is a state of sleep. Our sleeping experiences are not recollected, and we cannot bring them to bear upon the subject. If we could remember all that passed in sleep we might find nothing extraordinary in the acts of a person in a mesmeric condition. The neglect of MESMERISM. 537 this fundamental distinction seems to lie at the root of the confusion of the matter; and the only hopeful method of advancing into the labyrinth is by starting from the most obvious and familiar of the phenomena of sleep. To enable us to do this at all successfully, we must first disentangle sleep from certain other states into which it is often confounded. Sleep is frequently spoken of as a state of negation,and as such related to stupor or fainting; but a little careful attention will dispel this error. A faint is an arrest of all the animal functions: the heart ceases to beat, the lips grow pale, there is total insensibility, there is, in short, temporary, at least apparent, death. In stupor, although the heart continues to beat, it does so languidly and laboriously, there is no sensibility as in sleep-to any stimulus that can be applied to the system, there are no dreams, and there is no sense of refreshment on recovering from it. It is a dead, unnatural, unwholesome calm, not a living, natural, sanative repose. Stupor and faint are morbid states, sleep is essentially a healthy one. "Sleep, Death's twin brother, knows not death." Hence it is a misnomer, and one which has done much mischief from the erroneous idea it involves, to call those poisonous substances which produce stupor, Aypnotics. Narcotics or soporifics they are, but sopor and narcosis S are not synonymous with sominus. Sleep, then, we believe, along with some of the best physiologists who have written on this subject,' to be a positive condition of the system, beginning in all proSSee Burdacl's 'Physiologic,' vol. v, p. 185. 538 MESMERISM. bability before birth, and continuing till death. For there is great likelihood that the foetus in utero floats in its little ocean fast asleep, and only slowly after birth enters the full state of wakefulness.1 Its position is that of sleep. Many animals when they fall asleep resume their prenatal attitude by instinct; some seem scarcely to wake, as those born blind, till some days. Infancy is a prolonged sleep: and in our progress to second childhood, which too is little else than sleep, it is necessary for the preservation of our faculties that we should nightly return as it were to Nature's womb, to be quickened for the returning morning of a fresh birth. That there is a living mystery in these long years which we spend in sleep can scarcely admit of a doubt; and perhaps when the " soul, the body's guest," shall go into other regions of existence, the resurrection which is to reunite our separated elements will combine the double experience of all that we have learned in our waking hours, and all that may have been taught us when asleep. 1 It may be somewhat too fanciful for a scientific paper to suggest that if the child be asleep before its birth, it may in that sleep be visited by dreams, and those dreams may take their character from the emotions of the parent: and one might even imagine that some very vivid dream might be remembered in after life. Perhaps this idea lies in these verses of In Memoriam:"How fares it with the happy dead? For here the man is more and more; But he forgets the days before God shut the doorways of his head. "The days have vanished tone and tint: And yet, perhaps, the hoarding sense Gives out at times (he knows not whence) A little flash, a mystic hint." MESMERISM. 539 The more we ponder upon sleep (the great recurrent movement in the epic march of life), the more does its importance as well as its mystery grow upon us.. It is an aspect of the law which governs not only all sentient but also all material existence,-the mighty law of alternation: the succession of day and night, of summer and winter, the perpetual repetition of the modified past, which constitutes the present, and involves the future. And hence it can hardly be matter of surprise that the infraction of this great law should be attended with most direful consequences. Abstinence from food enfeebles and reduces the frame, but want of sleep disturbs all its functions. It is partial death,-death of our sleeping life. In sleep we return into the great telluric life from which we sprung, for out of the dust of the earth were we created. Not to sleep is to array this life against us; hence sleeplessness is attended with visions of all that is unnatural. It is not because ghosts are invisible by day that they are only seen at night, it is because they can only be seen by the eyes of the sleepless. Sleep viewed from the negative point may be defined a healthy condition, in which the conscious will of the sleeper ceases to control the mental and bodily operations. Both mind and body may continue active, and may and probably do act in obedience to laws as distinct and ab.. solute as those which govern the waking state; but the initiative impulse may be given by external forces instead of by the will of the individual. The will of a waking person may regulate the actions of a sleeping one. If the ear of a sleeper be tickled with a feather his hand will rise to remove the annoyance: if into his ear be whispered words of obvious meaning it frequently excites 540 MESMERISM. a corresponding dream. This seems the simple explanation of the amusing actions to which the very silly name of electro-biology has been given. To induce these acts a person is but asleep, and dreams are suggested to him; he sees and hears and walks as if awake, but in reality he is asleep, his will is dormant: he is told that a chair is a horse, he dreams it and acts a dream. There is nothing wonderful in this. It is not so uncommon for persons when fatigued to fall asleep while walking and to continue their walk. Innumerable examples of this are on record, nor is it unusual for them to hear and to see with sufficient distinctness as to avoid obstacles. This happens even in ordinary sleep, to say nothing of somnambulism. The mesmeriser puts a person to sleep, and by so doing acquires the control of his thoughts and voluntary motions as long as he is asleep. The only remarkable thing is the power of putting to sleep, and this peculiar sleep. The cataleptic phenomena produced by mesmerism belong to a different category, and are beyond the present scope of our inquiry. If we define mesmerism to be the power of inducing sleep in its various modifications and of communicating with the sleeper, so that while on the one hand the waking operator can influence directly his thoughts and actions, and on the other can receive from him in return an account or description of his perceptions, we exhaust all the higher phenomena of this state, including clairvoyance. For clairvoyance is neither more nor less than the admission of a waking person into the consciousness of a sleeping one. What this kind of consciousness is, whence it comes, by what laws it is regulated, we know absolutely nothing; nor can we expect to know anything MESMERISM. 541 except by examining it for itself. We know how we perceive the external world when we are awake, or rather we only know that certain mechanical contrivances are used to enable us to do so. We know that in sleep if there be perceptions of the external they are not produced by the apparatus of the senses that supply the corresponding waking ones. More than this we do not know. Ordinary vision is as great a mystery as clear sight. But it is an obvious contravention of all the laws of induction to attempt to explain the one by the other: we might as well try to estimate the effects of a piece of music or poetry by a mathematical formula, or to speculate on the probable longevity of an angel. And we consider all the theories which have been invented to facilitate the belief in clairvoyance (for we cannot suppose that even their authors could for a moment imagine they explained the phenomena) as falling under the rebuke of Lord Bacon, when he says: "The art and mind of man if it work upon matter which is the contemplation of the creatures of God, worketh according to the stuff, and is limited thereby; but if it work upon itself, as the spider worketh his web, then it is endless, and brings forth indeed cobwebs of learning, admirable for the fineness of thread and work, but of no substance or profit."' It is no part of our design to enter into a disquisition as to what mesmerism is; whether it be a form of terrestrial magnetism, or have a diabolic origin we must leave to the decision of natural philosophers and divines, and whenever they are all agreed we shall humbly bow to their decision. However, it does appear to us a reSC Advancement of Learning,' p. 41. 542 MESMERISM. trograde step in philosophy to expend time in attempting to ascertain the nature of any force: all we can hope to determine is the conditions under which it is manifested, and the laws which regulate its phenomena. Hence, with all deference to Baron Reichenbach and with all respect to Professor Gregory, we greatly prefer the old term of mesmerism to the new title of odyle. It is enough for us as physicians to try and discover what mesmerism does, not what it is: and it seems to us that mesmerism, however produced, is the hypnoticpar excellence. We have already indicated the immense value of sleep, and if mesmerism really be a sleep-producing agent over which we have certain control, its value must be immense. It is asserted to have another value, in making us acquainted with phenomena of disease by means of clairvoyance; into this, too, we shall briefly inquire. In the first place, however, we shall consider it in its direct therapeutic bearing, as enabling us to afford that exquisite repose to patients, the want of which we know gives rise to many positive diseases, as well as being in itself a source of indescribable suffering and distress: and in the following observations we shall speak entirely from personal experience which we have had of its efficacy in a few cases, and which has convinced us that mesmerism is quite indispensable for the successful treatment of a certain limited class of diseases. We do not mean to deny to it a larger sphere of usefulness, but in the wider range to which its professed advocates promote it, we believe it may merely rank as one of many useful appliances, whereas in the more limited sphere it stands entirely alone, as the only curative agent. MESMERISM. 543 Of course, by calling it a hypnotic we remove it from the category of strictly homoeopathic remedies; we do not consider its action in the cases we are about to speak of as homoeopathic. But as we never meant by adopting the homoeopathic law as our guide to deprive ourselves of our moral liberty as physicians, we need hardly observe that we consider ourselves perfectly justified in employing this or any other adjuvant which does not interfere with the administration of the minute doses we are in the habit of using, and we cannot but regret the tendency of the profession at present to cut itself into fragments, each representing a fractional truth. It seems to us just as rational that physicians should be called respectively, cathartic, diaphoretic, or emmenagogue, as water-cure or mesmeric doctors. I shall now briefly detail my own experience. The first case I shall relate is that of a lady about thirty years of age, of nervous lymphatic temperament, of a firm frame, vigorous in mind and body. This patient was formerly under the charge of a physician, by whom she had been successfully mesmerised. Before coming under his treatment, she had been for years delicate, and had suffered much from a short cough and pain in the lower part of the back. For this she had been bled, by an allopathic practitioner of considerable reputation, every week for many months without any advantage. When she first consulted me she complained of violent pain on one side of the head about the temporal region, almost incessant nausea, occasional vomiting, total sleeplessness, and a sense of restless uneasiness which made her quite miserable. I found the homceo 544 MESMERISM. pathic remedies usually beneficial in such cases of no avail, and at her own request I put her asleep by making passes slowly over the head and face. It required only a few minutes to induce the most profound slumber. I allowed her to sleep for about half an hour, and then waked her by blowing gently in the face. For some weeks afterwards she was perfectly free of all pain, both in head and back, her appetite was good, she had slept soundly every night, and in fact felt perfectly well. From time to time she had a return of her distressing symptoms, and they were always relieved for a period of at least four or five weeks by a repetition of this simple operation. I tried on one occasion making her gaze intently on a small object in the manner similar to Mr. Braid's method, and the result was equally satisfactory. In a few minutes she was fast asleep, and on awaking had the same sense of relief, repose, and restoration as when she had been put asleep by passes. It is now many months since she was mesmerised, and she reports herself to be in the enjoyment of perfect health. This simple case may be sufficient to correct an erroneous notion we find prevalent, that mesmerism if once used requires to be continually repeated, and that a patient becomes dependent upon it. A patient is dependent upon sleep, but the function once restored may continue normal without the repetition of the means first used for its induction. The next case is a very complicated and curious one. The patient is a lady of about thirty-four years of age, dark, of a pale complexion, great sensibility, and a very vigorous mind. Till she was eight years old she was a MESMERISM. 547 so as to be quite unable to speak. Besides she would frequently faint and lie as one dead for hours. Such is a general view of her condition during the autumn and winter of 1848. Having been formerly relieved of pain by mesmerism she requested me to try it, and the first effect was very remarkable: it did not induce sleep, but it gave a sense of rest, and there was an appearance of the catamenia which had been long absent. She described the sensation produced by the mesmerism as of oil poured over the nerves soothing and quieting them. The improvement in the general health of the patient was slow but steady, and mainly ascribable to the continued use of mesmerism. The sleep which had been wholly absent began to return, and was the unmistakable presage of further improvement. Her strength, which was sunk to the lowest ebb from want of sleep, and appetite improved wonderfully, so that she could walk miles. She still remained subject to attacks of tic at long intervals, and the spectral illusions continued for a time, but they too gradually disappeared, and she ultimately became perfectly strong and well. I may mention a simple experiment I made upon one occasion to satisfy myself and her that they were figments from within, and had no external reality. On one occasion she described a figure standing at the distance of about three yards from her in the broad daylight. I took a mirror and placed it behind the spot the intruder was represented as occupying, in such a way that had he been of veritable flesh and blood she must have seen his back. I then told her to look in the mirror and tell what she saw; she replied she saw the face repeated. Thus by a simple optical manoeuvre the unreality of her visitor was demonstrated. 548 M5ESMERISM. The next case is a very interesting one from the spontaneous appearance of some of the higher phenomena in mesmerism. The patient is a lady of about thirty years of age, of lymphatic temperament, large head, pale hair and eyes, and very short-sighted. She had been delicate from her childhood, and consulted me first about five years ago. At that time she suffered much from constipation and general weakness, but was able to walk about, although she frequently complained of pain in her back. At first she was much improved by homceopathic treatment, but afterwards on her return from the country her general health failed, and when she again came into town, about four years ago, she was almost constantly confined to bed or a sofa. She was subject to frequent attacks of retching, sometimes vomiting blood; she had little or no appetite. She frequently suffered from very violent spasms in the bowels and strangury, and complained much of pain at the lower part of the spine, aggravated by pressure or motion. She slept very little, and did not feel refreshed by the sleep she got. The catamenia were never regular. I was sent for late one night, and found her coughing incessantly. The cough was hard, hoarse, and croupy. She complained of pain about the larynx and trachea; the pulse was so rapid as almost to be uncountable. She was extremely hot, restless, and uneasy. She once had a similar attack, for which she was leeched and blistered, and did not recover from it for six weeks. Thinking it was not purely inflammatory I tried the effect of making passes over the face and throat, and in about MESMERISM. 549 fifteen minutes she was better and inclined to sleep. I gave her Aconite and left the house, but was re-summoned about three o'clock in the morning. This time I persevered more steadily in mesmerism, and had the gratification of seeing her fall fast asleep in about twenty minutes. I left her with injunctions to continue the Aconite should she awake. On calling about ten o'clock that day I found her much improved. She had slept for some hours, felt refreshed, and the cough although not gone was much abated. In the course of a few days she was restored to her usual state of health. The manifest benefit afforded by mesmerism induced me to repeat it regularly about twice a week, and she always slept soundly the night after it was done, and somewhat the following night. This in itself was an improvement. At this time the weakness in the back had increased to such an extent that she was constantly confined to bed, and unable to rise or even to turn herself without assistance. She had no power in her legs, and could not even move them. Being compelled to be absent from town for about six weeks, on my return I found her a very great deal worse. She had not known sleep during my absence; she was scarcely able to taste food, and the little she took she vomited; her pulse was small and quick; and she was so alarmingly weak that her friends expected her death. On re-commencing mesmerism the sleep was restored, and gradually the sickness subsided, and her appetite returned. By steadily persevering in it her general health gradually improved. She lost the excessive irritability which had been before most distressing, and as she herself expressed felt restored to a new life. hi the course of about fifteen months she was able 550 MESMERISM. to walk a little with assistance, and felt much more vigorous than for years. The severe spasms when they occurred could always be checked by mesmeric passes, and in short all the sudden dangerous attacks were under control, and there was steady progress towards a certain measure of health. One day while asleep she began to speak of something that was going on in the adjoining room, and upon my asking her a question she replied sensibly, although in a low and peculiarly modified tone of voice. Having thus discovered that she was in a state of clairvoyance, at each visit I put a series of questions to her about the state of her health, and what she saw in her body, and I shall now transcribe from notes taken on the spot some of these conversations. Are you asleep? Yes. How long will you sleep? Five minutes. Do you see your back? Yes. What is it like P It is white. Is it all white? No; at one spot it is reddish. Is it purple? Purply.

Is it less red? Yes., it is paler. She pointed out the colour it resembled most. During an attendance of many months I repeated my examinations at each visit., and I shall now give the general conclusions I have arrived at on the matter., after a long series of careful observations, and after reading the current literature on the subject. When Coleridge says, " Seeing is not believing, but believing is seeing," he meant something better than a philosophical paradox. And the more we reflect upon -vision, the more we shall be convinced that both memory 554 MESMERISM. and imagination have more to do with the process than we at first suppose. Ordinary vision implies two conditions, an external visible object and an internal seeing and conceiving faculty. So that it is well said we see what we bring with us the faculty of seeing. The perception of an uneducated person on looking at some wholly new sight is quite different from that of one used to examine the object seen. Sight affords the materials, but the mind constructs the picture; and the picture varies with the mind. The same holds good in clairvoyance. The person describes as he conceives he sees, but his conception depends upon many conditions. In the walking state the errors of sight may be corrected by the other senses or by changing the point of view. This is not possible in clairvoyance. So that at the outset we must expect great fallacies, and our observation has fully confirmed this anticipation. Of one thing, however, we are certain: that the images described by the clairvoyant are not derived from the waking person who puts the questions. Any one used to observe his own mind knows that there is a wide distinction between the active imaginative state and the passive recipient one. In the former it is full of images; in the latter there is none. Now I am quite sure that in the case I have just detailed the images described by the patient were not in my mind. Her mode of perception I do not even attempt to guess at, but I know that it was not derived from me, for I never had conceived, in her fashion, of the things she described. In trying to settle for ourselves the important question of how far these descriptions are trustworthy, we be MESMERISM. 555 come aware of certain important sources of fallacy. The most important is this: there may exist some kind of emotional sympathy between the mesmeriser and the person who is mesmerised. The emotions of hope or fear or anxiety which affect the waking person may be communicated to the sleeper. These emotions seem to act upon the imagination, and to mould to a great extent the sleeping vision. Hence I am inclined to disbelieve all descriptions which relate to subjects strongly affecting the feelings of the mesmeriser. Besides, there is the constant effort of imagination eking out what is seen, like a person peering through a mist at a dim object he is anxious to recognise. After 'these enormous deductions we find a residue of pure observation, but we have no means of ascertaining how far even this is to be depended on unless we have independent means of verifying it, which of course supposes the subject to be one patent to our waking faculties, and this narrows still more the possible utility of the revelations of clairvoyance. The practical conclusion I am inclined to come to is that mesmerism as a hypnotic agent is very valuable, that in certain rare cases the revelations of a clairvoyant may be of value in ascertaining the precise pathological condition of patients, but that it must be employed with extreme caution and reserve, as it is just as likely to mislead as to guide aright. On the moral aspects of the subject it would be out of place to enter, but I cannot refrain from making one observation, and it is this: that the relation of a physician to his patient is the most sacred, the most delicate, and -the most responsible which can unite two persons 562 SIR H. HOLLAND'S persons present, their dress, and many other minute particulars." If, then, in a sleep of morbid intensity it is proved that impressions took place which were afterwards remembered, we may safely conclude that in ordinary sleep the mind is supplied by hidden rills of sensation which become the source of an infinite variety of emotions and cogitations, mostly beyond the power of recall, but mingled in the texture of the mind as it is woven on the loom of time. Where there is memory there must have been attention -at least, to such a degree as to enable the mind to perceive an impression; and we may conclude, that even in the profoundest sleep, attention is never wholly absent. This accounts for the consciousness during sleep of the lapse of time, and also for the very singular fact that the slightest noise of a kind requiring the attention, will waken a sleeper who withstands the loudest uproar, if it does not affect him personally. We know of an officer whose duty required him to be on the alert against a surprise during the last seige, who was awakened by the first discharge of a rifle, while sleeping through the roar of all the batteries of cannon, in utter unconsciousness. With the large artillery he had no business, but he had with the musketry. Such axamples might be indefinitely multiplied. It is enough if we recognise the fact that in sleep we do not part with either attention or memory. This, then, is "the stuff that dreams are made of." They are the lines drawn on the sensitive surface of the mind by impressions made upon the body. Most fre. MEDICAL NOTES AND REFLECTIONS. 563 quently these lines arrange themselves into figures purely fantastic, one figure breaking in upon another like an unsuccessful photographic picture; at other times, under the influence of causes which affect the nervous system, such as opiates, the images assume more distinct arrangement, and are impressed more permanently, so as not only to become objects of waking recollection, but to remain so vivid as to confuse the mind, and to defy all efforts to adjust them to their proper significance. Thus we perceive how readily the indulgence in drugs which produce intense and pleasant dreams, such as opium and cannabis indica, become the fertile cause of insanity; for it is impossible to conceive a more perfect realisation of universal madness than would be presented by the world of sleepers rising, and acting each his own particular dream. Such is the state of the victim of delirium tremens: he is possessed literally by horrible dreams. Fortunately, we can avoid the causes we know to install dreams in the place of reason;-for the most part, they are poisons in the blood, perturbing the brain and nervous system. But far short of any such intense disturbances as to constitute permanent illusions after sleep, we may recognise as a cause of disagreeable dreams any alteration in the state of the blood which prevents it supplying the proper materials for the nightly regeneration of the nervous system. Hence the unrefreshing sleep in many fevers; probably from the retention of secretions which the emunctories are disqualified for removing. And another frequent cause of imperfect sleep and distressing dreams, is the insufficient quantity as well as the impaired quality of the vital fluid. Many a restless night is caused by going 56-1 STR B. HOLLAND'S supperless to bed, and in the present day, when out of opposition to late dinners, the delicate members of a family are regulated by their abstinence-enforcing medical attendant to a meagre early meal, it is very doubtful whether the advantages of an easier digestion are not countervailed by the starving of the nervous system deprived of its food during its time of repose. We can testify from frequent experience to the advantage of a moderate but substantial supper, in procuring sound and refreshing sleep for persons who out of respect to some code of health, have been in the habit of religiously abstaining from tasting food for some hours before going to bed. Besides the confused shadows left upon the mind by ordinary dreams, and the intense ones imprinted there by morbid states of the blood, there is another class which has given rise to much interest and speculation, but which would lead us, if the subject were pursued, into the wide wastes of mesmerism. We allude to dreams which have a distinct relation to the external world, presenting to the sleeper pictures of distant objects. Whether it be possible ever to include this subject in any purely scientific treatise, will depend very much on the spirit with which it is pursued by those who take a special interest in it. Mesmerism may be said to have advanced to such a point as to demand recognition by all writers of physiology as well as psychology, and the more recent and celebrated of the latter have frankly acknowledged this,' and have not hesitated to declare that we receive impressions from the external world by other SFor example, Sir William Hamilton, late Professor of Logic and Metaphysics in Edinburgh. See his ' Dissertations.' MEDICAL NOTES AND REFLECTIONS. 565' channels than the senses. This is a great step, and one which opens the door to endless speculation and inquiry, and this is closely connected with the subject of sleep and dreams. It is notorious how much influence, for example, atmospheric causes have upon the entire phenomena of sleep. Now if the only essential difference, viewed from the pyschological point, between sleeping and waking, be that in the former we cannot control the impressions made by external causes, but must permit. them to scrawl their signatures on the mind at random, while when awake we can repress the emotions and thoughts the same ever-acting influences would tend to evoke, it is manifest that these impressions may still be made, and enter unconsciously into the whole fabric of the mind's growth and structure. It is in this way we may probably explain the national differences of the modes of thought observable over the globe. How large a portion of the solar light goes to form the mind as well as the body of " the children of the sun " in eastern and southern latitudes, is a question fertile of speculation, and one which, when satisfactorily resolved, may account for many perplexing perversities in oriental philosophy and religion. It is along this line of inquiry, where, every now and then, physiology and psychology intersect, that Mesmer's temple stands, and we can only express an earnest hope that his votaries may strive after a philosophical method of pursuing their investigations; and we cannot here refrain from expressing our regret that a subject of such deep interest to all thoughtful minds, especially to those engaged in medical persuits, should have been degraded to such base purposes as to have become a scandal and reproach, instead of an 566 SIR H. HOLLAND'S honorable ally. The extravagancies and follies perpetrated by men calling themselves physicians, especially in America, is enough to make one blush for his profession. How any sane man can for a single hour give himself up to the delusion of spirit-rapping, is only explicable by presuming on his part a total ignorance of the fundamental laws both of psychology and physiology, but that physicians should patronise instead of explaining the fallacies, seems almost incredible. What are the alleged facts? simply these, that certain persons hear certain sounds, and that they cannot detect a physical cause for them. Well, what of that? If these noises have an objective reality, if they are caused by vibrations of air from an impulse given to a piece of wood, the thing that gives this impulse, must be a thing, that is, must possess the first attribute of matter, impenetrability; otherwise it could not act upon matter; if it be impenetrable it must have extension and form, and therefore it is not spirit, which is defined as being without material qualities. If a spirit be assumed, and we may freely admit the presence of spirits to any amount, the objection to their turbulent activity is simply the fact that hitherto the whole course of observation has more and more unequivocally demonstrated the position, that the spirit, the only one we know about, the human spirit, active enough, and mischevious enough, in all conscience, is quite powerless to act upon any form of matter without the intervention of a nervous system. To prove the connexion of the noise with a spirit, those who believe in it must first prove the presence of a spirit on other grounds, and then how being there without a nerve, muscle, or bone, it taps. But how much simpler the explanation of the phenomena 568 SIR H. HOLLAND'S circumvallation. On our return to our starting point we recollect the road we have taken, and the next time we set out on the same journey, we follow the same.path. If this road be dangerous to ourselves or injurious to others, we are driven out of it by our instructors, whether in kindness to us or out of fear for themselves interposing some new and greater obstacle, so that we have again to discover afresh the point of least resistance. Thus are habits formed and educated. Hence their enormous power for good and evil. For the road we know we come to walk with such ease and so full a sense of security and satisfaction, that in a short time all effort is at an end, and what was at first accomplished by anxious trial and constant exercise of will, becomes subject to laws which regulate involuntary actions. The exact method by which this takes place is not known. That walking is a most difficult achievement for an infant, and its first successful pursuit of knowledge under difficulties, is well known to all mothers and nurses, but what the change in the nervous system is, by which an act thus laboriously learned becomes one of utter unconsciousness-becomes transferred we may say from the brain presided over by the will, to the spinal chord which associates muscular efforts of a purely involuntary character, remains as yet an unsolved riddle. Habits may be said to represent for the individual the maximum of attainment with the minimum of effort. Can we then wonder that all novelties, such for example an entirely new method of medical practice, should be absolutely rejected by the mass of those who have formed themselves upon an old one? Can we be surprised that when they see a barricade in every street, they should raise an 570 SIR H. HOLLAND)S politicians may find in this an excuse for ascribing a certain sinister aspect to the efforts of the peace party in this country. How far habits injurious to health and full development of all the organs may be the origin of positive disease and malformation, and thus the source of monstrosity, is a most important question for all who have any charge of the public health, but the subject has not been investigated in a wide range, or with sufficient exactness to warrant any satisfactory conclusions. It is certain that many diseases of the nervous system, such as epilepsy and insanity, which arise from individual excesses or vices, are prone to assume a hereditary character. At the same time, there seems a much stronger tendency in congenital than in acquired deviations from the normal type to be perpetuated by transmission. Sir H. Holland gives some curious examples of this kind in the following passages: "' An instance is known to me of hydrocele occurring in three out of four successive generations in one family -the omission adding to the singularity of the fact, from its depending on a female, being a third in the series, in whose sons it reappeared. "c I am acquainted with a family in which there are three examples, the father and two children, of inability to distinguish red as a colour. Another example resembling the last is known to me, where three brothers and two or three children of their families have the inability to distinguish between blue and pink. Instances of hereditary defects of this kind are far from unfrequent. I have known squinting to occur in every one of five children, where both parents had this pe MEDICAL NOTES-AND REFLECTIONS. 571 culiarity. An example has recently occurred to me of that remarkable affection, the suffusio dimidians, existing in a father and his daughter, and brought on in each by circumstances singularly alike. The frequency of blindness as an hereditary affection is well known, whether occurring from cataract or other disease of the parts concerned in vision. The most remarkable of the many examples known to me, is that of a family, where four out of five children, otherwise healthy, become totally blind from amaurosis, about the age of twelve, the vision having been gradually impaired up to this time. What adds much to the singularity of this case, is the existence of a family monument, long prior in date, where a family ancestor is represented with several children around him, the inscription recording that all the number were blind. "The repetition of cases of deaf and dumb children in the same family is familiar to those who are concerned in institutions for the relief of this congenital defect, and will be afterwards noticed in reference to another singular modification of this fact. " In one family I have known four or five cases of the peculiar tremor tendinum of the hands and arms, which is sometimes called the shaking palsy, and which here occurred in young persons of 16 or 18, as well as in those more advanced in life. In this case, too, as well as in another of the same affection, I had proof of the peculiarity having gone through at least three generations. "Defects or peculiarites in the form and setting of the teeth, as well as in the hair or nails, are often hereditary; and lefthandedness, from whatever cause it pro 572 SiR H. HOLLAND'S ceeds, I have more than once observed to take the character of a family peculiarity. In a family where the father had a singular elongation of the upper eyelid, seven or eight children were born with the same deformity, two or three other children having it not. I have known another family in which five daughters resembled the mother in having a large growth of hair on the lip and chin. In like manner I have seen enlarged tonsils occurring in almost every individual of a large family, without other cause by which to explain it. A case is recently known to me, where the patella was wanting both in father and son." " I find many examples among my notes of what must be deemed hereditary tendency to heart-disease; and such in truth are familiar to all observers. In one of these, four brothers died between 60 and 65, of organic disease of the heart, with prior cases of the same kind in their family. In another case, which I note here as having most recently occurred to me, I find three cases, including one of the morbus ceruleus, in three successive generations. It is unnecessary to add others. " Of hereditary obesity I have seen some very curious examples-the most recent that of a family in which out of two generations four individuals died of the results of excessive accumulation of fat, producing diseased action of the internal organs, and dropsical effusions, two other cases of the same tendency existing in the family, under distressing though less urgent forms. Several cutaneous disorders evidently tend to become hereditary, whether from peculiarity in the texture of the skin, or depending on the general temperament and state of the circulating fluids. I have lately seen three cases of MEDICAL NOTES AND REFLECTIONS. 573 Psoriasis in the children of a family where there is strong predisposition to gout, a conjunction I have observed in many other instances. Certain impetiginous eruptions belong also to a family constitution, such as is often termed scorbutic, and are obviously transmitted from parents to children. "Icthyosis is occasionally seen as an hereditary disorder. I may notice here another singular disease, the pellagra of Lombardy, in which, together with the peculiarity of a local limitation, there occurs a very singular succession of symptoms, beginning with a cutaneous affection of leprous character, passing through various stages of cachectic disorder, and ending generally after the lapse of a few years, in fatuity or death. I have had much opportunity of observing this curious disease in all its forms. There can be no doubt of its hereditary nature, though there is difficulty in tracing it back, in Lombardy, for much more than a century, and equal difficulty in assigning the causes which give it existence in this district alone. The peculiar form of leprosy prevailing in certain parts of Norway, comes under the same description of hereditary disease, and is further analogous to the pellagra in the fatuity it often produces. In the hospital at Bergen I have seen this singular disorder in all its forms and stages. Diabetes, from my observation (and Dr. Prout states the same fact,) has sometimes an hereditary character. Enuresis in children, from whatever source arising, occurs sometimes in so many individuals of the same family, as to make it almost certain that it has a common congenital origin. What is not less remarkable, as an instance of similar speciality, emphysema of the lungs has been ascertained MEDICAL NOTES AND REFLECTIONS. 57 575 diathesis, to which I cannot doubt from experience that some forms of asthma are closely related. "C Every physician will recognise the general tendency to hereditary character in disorders of the brain and nervous system. This is a remarkable part of the subject, involving, as it does, every variety and degree of morbid affection, from simple headache to the worst forms of epilepsy, apoplexy, and palsy. I shall hereafter notice in relation to another part of the subject, some singular examples in its illustration. The topic is further one of deep interest, as including the various conditions of hereditary insanity, instanced not merely in particular families, but even in. districts and communities, where, from local circumstances, there has been little intermixture with the rest of the world. From these facts well attested to us, we gather the important conclusion that some deviation in physical structure, whether obvious or not, is the cause of the aberrations it presents. In no other way can we conceive the transmission of the tendency from one generation to another. It m-ay be that a part of the fabric of the brain is concerned, far too miniute for the most subtle research to follow; and this, indeed, might be presumed, looking at the nature of the functions affected. But still, whenever the transmissions occur, we are bound by all analogy to infer the presence of a morbid, material cause, upon which the phenomena primarily depend. "CCThere is much that is curious in the tendency to headaches thus transmitted by descent, and often going through whole families with similar character. The cause here presumable varies in different instances. Sometimes, and especially, perhaps, where they are periodical, 576 SIR H. HOLLAND'S the affection may belong to the gouty habit, and to the matter of gout in the circulation. In other cases, abnormal structure of the vessels of the head may be concerned. In others, again, some peculiarity in the nervous substance itself. " In hereditary affections of the nerves, as in those of other parts, it is extraordinary in what minute peculiarities the tendency often shows itself. It is difficult, indeed, in some of these cases to distinguish what is due to imitation alone; but in other instances where this is excluded by circumstances, we find, nevertheless, nervous habits and disorders of the parents reappearing in the offspring to a singular extent. "These entailed disorders are certainly more numerous than is generally supposed; and, probably, the source of many morbid states, apparently remote in kind. As respects their origin, they may all be referred to the general principles we have already laid down. " There are some examples of abnormal structure, or disease, which, though frequently occurring in detached instances, yet are so especially numerous in certain localities, as to afford suspicion in the absence of other sufficient causes that hereditary tendency is much concerned. Such is the goitre of particular districts, no consistent explanation of which has yet been given, founded on local circumstances of climate, or mode of life. The plica polonica prevailing almost exclusively along the course of the Vistula, is another instance to the same effect. I might apply the same remark, though with greater doubt, to that curious affection, the trismus nascentium, prevalent in particular localities, and these widely different in all physical circumstances. The 578 STR H. HOLLAND'S ing to one idea, into other living beings created according to another idea. And of this in spite of the apparent change of species in the marvellous metamorphoses of lower animals, nature has as yet given us no instance among all the facts which have been observed; and there is, therefore, an almost infinite inductive probability against it. As far as we know yet, though all the dreams of the transmutationists are outdone by the transformations of many a polype, yet the species remain as permanent and strongly marked as in the highest mammal." It is not easy to trace the origin or to define the conditions of instinct. To those who take pleasure in contemplating the universe with all its created inhabitants as the expressions of a divine and ever-acting Power, whose thoughts so far resemble those of the human intellect as to follow a regular sequence moving along a course of unerring logic, although ages intervene between his footsteps (to borrow the language of Guizot), there is nothing either strange or repulsive in regarding the class of instinctive actions as mental operations unconsciously subject to unknown laws; this seems to be the notion which Laplace intended to convey by the phrase of there being animal affinities analogous to those which cause the molecules of a crystal to approach one another, and assume definite arrangement. But to those who delight to dwell upon the triumph of the human will in subjecting to its own purposes of good or evil the whole machinery, whether sentient or material of the outer world, there is something humiliating in tracing from the proud pre-eminence, where some Titan of his age lords over all, the roots of his existence, so to speak, beneath MEDICAL NOTES AND REFLECTIONS. 579 the surface, where they become subject to the same laws which control and regulate those of the most insignificant insect. It is this contrast in man between a domineering will and intellect, and a subjected bodily nature, that gives such interest to the subject of instinct. And yet, perhaps, in the highest forms of human existence, the two may be brought into unison with mutual advantage. For, after all, if we consider instincts narrowly, we shall find. that they imply either peculiar sensitiveness to noxious influences, or special impulses towards actions of a character beneficial either to the individual, or the species of which it is a member. The animal perception of noxious influences is exemplified in the retreat of birds friom pestilential districts, in the general rejection by animals of poisonous food, and in the general avoidance of what would be dangerous to their well-being, while their active instincts induce them to go through many actions in a state which Cuvier likens to somnambulism, from its unconsciousness on the part of the individual of any benefit to be derived from it. The difficulties that are chiefly dwelt on by Sir H. Holland, seem to arise for the most part from a sort of tacit demand that every action shall have the accomplishment of a preconceived object for its motive. Now, doubtless, this is true in regard to ourselves in a great measure, when we have reached maturity, and becomecapable of analysing our inducements to change our habits of action, but it is not true of us in infancy, nor is it at all necessary to suppose any such process of mental anticipation in the mind of an animal. There is in fact no more real difficulty in conceiving a series of impulses compelling a succession of corresponding acts MEDICAL NOTES AND REFLECTIONS. 581 pression rather than the regulation of instincts, nature may avenge itself "by stopping the supplies," and so paralysing the constitution. If we were to follow this reflection to its natural consequences, it would lead to the consideration of some of the most embarrassing questions submitted to us in our capacity of medical advisers, by persons who have to suffer from a conflict between what we may almost call individual and social morality, whose health is destroyed by submission to laws absolutely necessary for the general welfare of society. Any attempt to adjudicate in such distressing cases is beyond the scope of the physician's office; all we can do is to state the consequences and leave the decision to the individual. It may be that duty shall require the sacrifice of health: this does not entitle us to advise an evasion of the duty, but merely to state the facts. As to the seat of the instinctive appetites and emotions, although probably always in some part of the nervous system, it would seem to be various in different species of animals. For example, a decapitated butterfly will exhibit as much animation in the presence of one of an opposite sex, as when in possession of its head, with all the organs of the senses there concentrated, while the destruction of even portions of the brain, will annihilate in animals higher in the scale, all the perceptions and emotions represented by the insect's excitement. An inquiry into the seat of the emotions, naturally conducts us to phrenology, a subject treated by our author in rather a superficial manner. It is one which admits of two distinct points of view, which have not, perhaps, been sufficiently discriminated. Accepting 582 SIR H. HOLLAND'S as an established fact that the brain is the organ on whose integrity all mental operations depend, it is an obvious suggestion that as, on the one hand, we have a complicated series of very dissimilar mental attributes, and on the other a no less complex organization, we may infer that each of the various primitive emotions and faculties will have a corresponding cerebral locality. " Eminent men in all ages have acknowledged this dependence of the faculty of thought upon the body: of these, I need only mention (we are now quoting Prochaska)' Hippocrates, Galen, Descartes, Abraham, Kaw Boerhaave, and Gaubius. The force of truth made Tralles also subscribe to this opinion, for, although he carried the doctrine, that the mind is independent of the body too far, yet he observes, it is, indeed, certain that experience teaches us that so long as the soul is connected with the body, a well-established brain is absolutely necessary for it to think, imagine, reproduce ideas, and judge concerning them." Ernest Platner, also, in his elegant essay, de vi corporis in memoria, observes, "since such are the facts, it is manifest from the observations already made, as to the mode of perception, that every one of our senses is put in action by the common agency of the body and mind, so that no sensation or thought can be produced by the mind without the body, nor by the body without the mind. And this doctrine that the soul so long as it is connected with the body, can neither think, nor have self-consciousness, without a properly constituted brain, derogates certainly in no degree from the immateriality and 3 Unzer and Prochaska, on ' The Nervous System,' p. 445. MEDICAL NOTES AND REFLECTIONS. 583 immortality of the soul, which God by special favour can endow with an eternal consciousness of itself, and of things external to it, although the body it had inhabited be destroyed-a doctrine we are taught to believe by religion, which also in every age has been desired by mankind, and which great philosophers have approved by their assent." So much, then, we may take as an acknowledged fact in physiology, and it is a perfectly legitimate advance from this broad basis, to attempt to ascertain by an examination of the brains of those who when alive exhibited well-marked peculiarities of character, whether certain portions of that organ do not correspond with certain faculties. The difficulties of pursuing in a rigidly scientific method this investigation, are obvious enough, and exemplified by the obstacles which required so much time and genius to overcome them, before the much simpler facts of the relation of nerves to different senses and other functions were finally established. The other point of view from which phrenology may be regarded is that of an attempt at an accurate physiognomy of the head. Every part of the body is indicative of the character of the whole individual in a greater or less degree; the hand may be called a hieroglyphic, legible perhaps to a mind of angelic power, of the perceptions of all the relations involved in every part; and how much more may we expect from the head, the capital of the human fabric, the grand distinctive feature of man? It is surely no mean task to endeavour to fix with precision the meaning of every curve and line, and a task which, if pursued with the clear idea of the knowledge we may thence derive, is likely to be attended with 584 SIR H. HOLLAND'S success. But it would perhaps have fared better with phrenology if its cultivators had kept to this idea instead of confusing a question in itself sufficiently perplexed by the introduction of another element altogether, that is, the relation of the form of the head, not to character only, but to the brain also. It may be perfectly true that a head broad behind, with a corresponding broad and a thick-set neck, is an indication of a large endowment of the faculty, which the phrenologists out of respect to the race of novelists designate as No. 1, and it may be equally true that this function of the cerebellum is to preside over complicated movements. Why, should the one set of observations be held to clash with the other? At the least we may suspect premature generalisation on the part of the phrenologists in this direction. It would be out of place here to enter upon the objections raised against the system from the psychological side, as giving an imperfect analysis of the mind, and overlooking some of the most essential difficulties which lie upon the very threshold of all attempts to catalogue the mental faculties of man. Perhaps it is oxving to such omissions that M. Comte, whose sympathies should incline him to a favorable judgment of the labours of phrenologists, pronounces against them the severe sentence, "that they do not seem to have even perceived the difficulties that must be overcome before their system is accepted by philosophers." However this may be, there is one thing quite certain, that until the system is universally accepted, or at least much more generally than. at present, it is a great error on the part of those who describe the localities of the symptoms of the head, to adopt a phrenological nomenclature. Descriptive ana MEDICAL NOTES AND REFLECTIONS. 585 tomy is a science, like physical geography, altogether independent of hypotheses. Where should we be now if instead of describing symptoms as affecting specified regions of the body, they had been allotted to the supposed functions which such regions covered? What could we make of a pain in the region of melancholy, or envy, or anger? And yet at one time the liver and the heart were as firmly and generally believed to be the actual seats of emotion, as the different portions of the brain are now. To those who are interested in the development of this subject, we might suggest the importance of not too rigidly circumscribing mental capacity to cerebral development, but embracing in their inquiry the whole of the nervous system, with many parts of which, as the ganglionic, we are as yet but imperfectly acquainted. We know that in the lower tribes it is the seat of most of their impulses, and it may be that the impulsive character of mind which enables genius to leap from height to height, while talent, however great, has to ascend and descend with painful effort the intervening space, may be dependent upon a more liberal supply of ganglionic nerves, which imbibe with unquenchable avidity all the influences of external nature, and thus feed with extraordinary bounty the faculties of emotion and conception, so as to give rise to a creative energy by which they summon into the world of matter and observation truths which till then had been held unrevealed by the ocean of possible realities which surrounds our little island of achieved knowledge. The only remaining topics in this volumc about which 586 SIR H. HOLLAND'S our limits permit us to linger, are, " the effects of mental attention upon bodily organs," and "memory as affected by age and disease." The effect of directing our observation upon our own organs is a subject of much importance in reference to the proving of medicines, and one which has of late attracted the attention of physiologists by the interest excited by Dr. Mayo's observations and the magnetescope. It is yet involved in great obscurity. All we positively know is, that if any particular organ of whose existence we are conscious by sensation, such as the heart or the stomach, be made the subject of thought or attention, this mental attitude or exertion may induce certain changes in that organ which becomes the subject of consciousness. We thus have a self-deranging power within us. How this is effected is difficult to say. We must suppose that there is constantly present a dim perception of the existence of these organs, derived from certain nerves of sensation, and when we are in perfect health the accumulated impression is one of well-being, or what has been recently called euphoria. We may here remark that this state of euphoria in excess is sometimes the precursor of some serious attack of disease, and in such a case we may suppose that the exciting cause of the paroxysm is the excessive development of nervous power in the organs of organic life. The diseases in which this has hitherto, been chiefly observed are of a spasmodic and nervous character. We have noticed it mother cases, however, and have had under treatment a lady affected with a singular kind of bilious diarrhoea. The prominent features of her 588 SIR H. HOLLAND'S derangements of these organs so produced is carefully observed by the mind. We may go even a step further in simplifying the problem, by suggesting that the will does not act directly upon the organs affected, but indirectly, by inducing in the mind an attitude of anticipation analogous to the emotion of anxiety, so that the whole circle is represented by the following acts;--first an act of attention directed to either, let us say, thestomach or the fingers; second the prolonged attention excites an emotion of longing anxiety; third, this emotion acts through the nerves proper for its conduction, either upon the sensitive surface of the stomach, or upon the muscles of the fingers; and fourth and lastly, we take cognizance of the sensations produced in the one directly, and in the other indirectly, by observing the muscular tremors magnified by mechanical contrivances, such as the divining rod, or magnetescope. Such seems to us the rationale of the whole mystery. In regard to its relation to homoeopathy all we have to say is, forewarned forearmed. So obvious a source of fallacy is to be carefully guarded against. And when Sir H. Holland says, speaking of the effects of minute doses of apparently inert substances, in deranging the health, " We find the proofs (even as they come from the founder of the doctrine) to consist principally in the simple assertion of the subject of the experiment, unchecked, as far as we can see, by any regard to the phenomena now before us, though so absolutely essential to the truth of all conclusions thus obtained," we say in reply that it is quite plain our learned author, however well he may be acquainted with Aristotle and Hippocrates, did not take any pains to investigate this 590 SIR H. HOLLAND'S by that of the individual, and to be alive to the distinction of memory and recollection. Memory may be defined as the accumulation of mental impressions.. We are obliged to restrict it to mental, for the impressions made upon the senses, such, for example, as those of sound, or light, or smell, are not properly the subject of memory, for they cannot be recalled either by an act of the will, or by association. This is a striking fact, which touches the confines of sensations as separated from ideas. Properly, we have no control of our sensations; they are the handwriting of nature upon us. The characters we cannot alter. If we could, the integrity of the senses would be at an end, as they are when the mind recalls sensations in its morbid state, and becomes subject to illusions of the senses;--a subject of extreme interest as a phenomenon of disease, but from its rarity, and manifestly morbid character, testifying to the truth of the proposition, that as a rule, sensations are not within the province of memory. The difference between memory and recollection may be compared to that between the possession of property and a supply of ready money. The proprietor of a gold or diamond mine of incalculable value, might starve in London from the want of a penny; and the loss of the power of recollection, produced by some accidental and purely bodily cause, may give the appearance of an entire failure of memory. We find in this chapter some curious examples of this. " A. case of slight paralytic affection," says Sir Henry, " is at this time before me, where the perceptions from the senses are unimpaired; the memory of persons and events seemingly correct; the intelligence only slightly affected; the bodily fune MEDICAL NOTES AND REFLECTIONS. 591 tions, though feeble in power, not otherwise disordered; but where the memory of words for speech is so nearly gone that only the single monosyllable 'yes' remains as the sole utterance of all that the patient desires to express; even when a simple negative is obviously intended, no other word is used. In another case of recent occurrence, where, in sequel to a paralytic attack two years before, the memory of words had been greatly confused and impaired, I found them all regained and brought into right use, except the pronouns, which were almost invariably substituted one for another. In a third case, where the patient, affected with hemiplegia, at a very advanced age passed into a state of low rambling delirium, a few days before his death, all that he spoke, whether in answer or otherwise, was in French-a language he had not been known to speak at any time for thirty years before. This continued until his utterance ceased to be intelligible altogether." To this form of imperfect recollection Sir Henry suggests the designation of dislocation of the memory. The dislocation of words while the train of thought is unbroken, is sometimes curiously exhibited. It is related in Sir Walter Scott's life, that while dictating some of his novels-which he only did. when he was prevented by illness from writing himself-the amanuensis was sorely puzzled by the utterance of a word having no conceivable relation with the immediate context; but after he had proceeded some lines in the composition, this same word then again appeared, and this time in its right place. It would seem that the thinking had gone so far ahead of the expression, and that there was 592 SIR H. HOLLAND S going on simultaneously a process of continuous thought, and the delivery of that product to the keeping of the memory, which gave it forth in a purely mechanical fashion. This suggests the important distinction between the memory from association of propinquity, and the memory of analogy. By the former, we recall objects and events in the order in which they were presented to the senses; by the latter, they return in connection with other facts, to which the mind finds them to be like. Learning a catalogue, or a page of a dictionary by rote, is an effort of the memory of propinquity; the composition of a theme, in which all the known facts are arranged in reference to the subject of the composition, is an illustration of the memory of analogy. The first is necessary for excellence in all technical knowledge; and having it in abundance gives great readiness, and the power of rapid decision; while the other is required for all efforts which demand the combination of invention along with recollection. When this distinction is not recognised, it is apt to induce an entirely false inference in regard to questions of veracity. There- are men-of whom we may take Coleridge as a type--who, with an enormous power of acquisition, seem to have little consciousness of the difference between what they have acquired, and what they have created. The memory of propinquity is overborne by the memory of analogy. The fruits of other minds are stored unlabelled in their own, and reproduced without acknowledgment; and then the critics "cc cry havoc, and let slip the dogs of war." This is no barren subject of investigation even to the physician, who must be aware of all such distinctions in giving an MEDICAL NOTES AND REFLECTIONS. 593 opinion upon points relating to insanity, and the enfeeblement of the mental powers by age and disease. The effect of bodily weakness in paralysing the recollection, is well attested; and we meet with a curious illustration of it in this chapter. The author, who among his other accomplishments, seems to speak German with ease, descended a mine in Germany, and having fasted all day, and undergone much fatigue, found to his dismay, when at the bottom, that all remembrance of that language had fled as entirely as 'Nebuchadnezzar's dream was forgotten by that monarch. Whether he was fortunate enough to meet with a Daniel 'who recalled the language, and the interpretation thereof, we are not informed. We are also told that the recent influenzas have been characterised by a certain enfeebled power of memory, even at their commence-.ment; and we call special attention to this fact, as it may give an important indication in the selection of the specific remedy for this epidemic. While, on the one hand, we thus observe as a frequent occurrence the loss of recollection without that of memory, on the other hand we occasionally meet with the converse, where the whole mental action is due to what may be considered an almost mechanical reproduction of the image presented to the mind by the senses. The most striking example of this is in the phenomenon which Romberg calls " the echo." In certain states of cerebral paralysis, the patient repeats the words spoken, and this is the only symptom of intelligence afforded. Thus, in one case he relates of a girl affected with some cerebral disorder, when he said " Put out the tongue, raise the arm," the patient repeated his words, but 38 596 SIR II. HOLLAND S were to be found in the writings of one Samuel Hahnemann. But the open secret, the true talisman of success, that only requires candour and courage to be known, is passed by, and the secrets of no practical value buried in the vestiges of former ages or remote countries, are diligently hunted after as being more worthy of a member of the College of Physicians and 'the Royal Society of London. We cannot conclude without adverting to the chapter entitled, " On points where a patient may judge for himself," for we fully expected to find among the first, as by far the most important, a patient's right to select his own medical adviser. This indefeasible right of a free-born Englishmen is not sufficiently recognised, and yet surely it is involved in the " Habeas Corpus" act! We trust that before there is any rash legislation touching this liberty, the opinions of constitutional lawyers will be asked, and that the descendants of men whose ancestors won from kings immunity from arrest, and from being carried off to prison, will not tamely submit to the usurpation of colleges, and the risk of incarceration in their own domiciles, guarded by sentries armed with lancets. This primary right of every sick man, Sir Henry does not advert to, but expatiates on the prospects of consoling all who seek our aid by assuming as encouraging and pleasant an aspect as we can, and indeed suggests the picture of a most amiable and courtly physician, one well qualified to gain public respect, and well deserving of the honours he has attained, although, perhaps, not quite rising to such an ideal as is represented by Leigh Hunt in the following passages, with which we shall CHAPTER XII. ON CHOLERA.1 "My experience of this department, brief as it has been, strongly impressed me with a sense of the great want that is now felt of some systematic record of cases of Choleraic disease, their treatment and results, with a view to determine, in so far as may be possible, the best mode of meeting this formidable epidemic. Hitherto, no'successful attempt has been made to collect such a record; and as I find that my feeling of the want is very generally shared by the medical profession, I have obtained the sanction of Her Majesty's Government to the nomination of a Medical Council representing all branches of the profession. ** * * By means of a return in the accompanying forms, the observations of all qualified practitioners on the cases that come under their care, may be collected and made available for determining the laws which regulate choleraic disease, and the effects of the different systems of treatment now in use." Thus wrote the President of the Board of Health to the medical profession, addressing to them this general invitation, and nominating a medical council having the 1 'Report of the Committee for Scientific Inquiries in relation to Cholera Epidemic of 1854,' presented to both Houses of Parliament by command of Her Majesty. i 600' CHOLERA. made into the state of these universal influences in districts actually infected with cholera;-and " 3d. With the object for increasing for our profession the present insufficient resources of medical treatment, we have endeavoured to procure comparative records of various therapeutical experience successful or unsuccessful, and have invited from persons versed in such inquiry, an elucidation of those questions in the practical pathology of cholera which appeared to us most urgent for solution." "When persons, not accustomed to accurate investigation," observes the writer of this report, "attempt to compare together the results of various treatment, as tested by death or recovery, they are seldom sufficiently on their guard against the immense fallacy of leaving unexpressed the degrees of the disease, against which this or that medicine has prevailed." Admitting to the fullest extent the truth of this maxim, we shall now attempt to determine from the data afforded by the information given in the tables before us, what we should anticipate to be the mortality of 33 cases of cholera, 22 of which passed into collapse in Golden-square between the 10th August to the 8th of Oct., 1854. The three questions to be answered, in order to obtain this result, are-first, whether the number of collapse-cases was under or above the average, for this is one of the most certain tests of the severity or leniency of the disease;-second, how far the locality was likely to operate as a favorable or unfavorable element in the course and result of the cases;-and third, whether the time involved a mild or malignant period of the epidemic's continuance. In CHOLERA. 601' reply to the first question we learn, at p. 17, that out of 3596 cases 2431 passed into collapse, so that by the simple rule of three we know that, to afford an average mortality, 22 out of the 33 should have done so in the Golden Square Hospital. This is exactly the number stated in the tables, so that we may be confident that the cases treated there were a fair sample of those treated over London. The mortality (omitting fractions) of these 2431 cases was 66 per cent. or 1627 persons. In short, the number died that a person acquainted with the average mortality of this class of cases would have expected to die. So much for the first question: let us now ascertain the reply to the second. What was the condition of Golden Square? Was it healthy or otherwise? Again we quote our book, p. 49. "In the three registration sub-districts of St. Ann's, Golden Sqmuare, and Berwick Street, together comprising a population of 42,000 persons, it appears that there occurred 537 deaths from cholera, being at the rate of 128 to every 10,000 inhabitants, while the general chorera-rate was only 60 to the same nmnber." " A striking feature of the outbreak was its extreme suddenness as measured by the large number of persons simultaneously attacked. Its greatest local diffusion appears to have been reached on the second if ilot on the first day from its commencement; it remained of equal prevalence for two days, and on each of the two following underwent a decline of 50 per cent." We find, our sample of cholera to have been taken from the part in all London where the disease was most intense and destructive. Nay, we are wrong in saying taken from it, but treated in it-a most important 602 CHOLERA. difference. The experiment was made in the veiy focus of the disease, where, in addition to the poisoned well of air in which the patients lived, they had also to contend with the depressing moral influences of an awful and overwhelming mortality suddenly falling upon them without warning, and terrifying them by the appalling rapidity of its execution. The only remaining condition we must ascertain is, how far the period from the 10th of August to the 8th of October was likely to embrace the epidemic in its mature or its incipient and declining malignity. To this question we receive, at p. 72, of Dr. Sutherland's supplementary report, the following satisfactory reply:-The number of deaths from cholera in the week ending the 12th of August, was 644, in the week ending the 19th, 729, and the ascent of the mortality throughout September, the month in which almost the whole of the 31 patients were admitted into the Golden Square Hospital, is represented by a mortality on the first week of 1277; on the second, 2050; on the third, 1549; on the fourth, 1284; and on the fifth, of 740. Thus we see that the conditions of the experiment fulfil the most stringent requirements of the writers of this report. The cases were treated at the height of the epidemic in the locality where the disease was most mortal, and they presented the average number of collapses. The only objection to which the inference from the success is open is, that the number treated was too small to establish so important, and to the medical world so improbable, a fact. But whose fault is this? Certainly not ours. Surely if the Board or Medical Council have thought it worth while to record that out of 11 cases treated with Calomel in CHOLERA. 603 small doses 7 died, that out of 8 cases treated with larger doses of Calomel 8 died, that out of 8 cases treated by Salines 7 died, and many more equally consolatory facts derived from the returns of hospitals and private practice, it might have been worth while to place on record that out of 22 collapse cases treated by Camphor, Veratrum, Arsenicum, and other remedies, 20 did not die but only 7. Surely this fact may be supposed to be of interest to the public, for whose benefit they were appointed to their office, and at whose expense these tables are published. When pressed for a reason for their strange omission, they said the remedies we used were unknown. However, this is not true, almost all the medicines used by us in cholera are to be found in Dr. Paris's therapeutic work. That he was ignorant of their real value is certain, but still he had what may be called a bowing acquaintance with them, so that he could not plead medical decorum as a reason for ignoring them. The absurdity of the conduct of Dr. Paris and his coadjutors has been already so fully exposed, that here we shall only add, before passing on to other parts of the report, that there is so transparent an uneasiness and distressing equivocation in his reply to the demand of the President of the Board of what have you done with the homceopathic statistics? that he and his fellows present the hopeful spectacle of what the old divines call sensible sinners, and we trust that the next time we have the pleasure of encountering them, they may have advanced into states of more secure conversion. As soon as we leave that portion of the field of investigation where professional prejudices interfered and enter the ground of pure science, we find a great improvement 608 CHOLERA. period, that ending the 2d of September, the excess amounted to 6-. After the week ending the 14th of November, the temperature was below its average till December." Although we believe that this has generally been observed, yet there was an important exception in Edinburgh which we shall exhibit in a tabular form rather with the view of limiting the importance given to the generalization than of disproving its accuracy. It will be seen by the following tables,' that during the greatest prevalence of cholera the temperature was much lower than it was in the same period of the preceding year. When there was no cliolera. 1847. Morn. Even..Min. Max.

What a strange confusion of ideas inl the brain of the scientific committee this paragraph exhibits! Tfhe cholera is no longer a disease, but a poison-not only a poison, but a bowel poison! The whole question of the pathology which professes to be treated afterwards., and is afterwards settled by an unsettling mark of interrogation, is here dogmatically decided by an inference! We are taught to speak of cholera as a bowel poison. By an ingenious abuse of purely hypothetical language in framing a statement upon the amount of heat in the air, an attempt is made to win belief for a notion, the grounds of which have not yet been even stated, and which, when they are brought forward afterwards by the same writers, are by themselves admitted to be insufficient. After so glaring an illustration of setting at defiance the fundamental principles of induction, one of which is the avoidance of conjecture in the statement of observed phenomena, what confidence can we repose in this national committee for scientific inquiries? One of the most curious and interesting observations made with regard to the state of the atmosphere was its increased weight during the prevalence of cholera. This fact was noted during the last epidemic by Dr. Prout, and it has since been confirmed by Mr. Glashier. Thle explanation given of it is, that it depended upon the diffusion of some gaseous matter in the air; and in connection with this the remarkable absence of ozone at all the stations where the air was examined in the cholera districts, seems to indicate the presence of some poison39 612 612 CH OLERA. have been in operation, and where it is doubtful if even any of them wvere in existence. It is our proud boast that the sun never sets upon the British flag, and it would be well if the extent of our territories were put' to the profitable use of instituting a series of accurate investigations of the local conditions which attended the appearance of an epidemic whose circuit has now embraced the whole of the British dominions. Thus we might arrive at a knowledge of what is essential and what is merely accidental in the phenomena not only of this but of all epidemics. Indeed it is impossilble -not to be struck with the undue importance attached to causes of a purely local kind, such as an unwholesome supply of water or too dense population, in dealing with so broad a question as the cause of a pestilence as deadly at sea as on land, confined to no latitude, restrained by -no peculiarity of national habits, strewing the desert with corpses as well as overwhelming the densely populated cities with destruction. One of the best-established facts in regard to cholera is the effect of local elevation. This has been generally observed in previous epidemics, and now we find it stated with scientific precision. "The distribution of the choleraic attacks (although in widely different degrees of frequency, and perhaps also of severity) throughout the whole metropolitan area, seems to establish that the cholera leaven, be it what it may, was scarcely less diffused in the districts that suffered the lowest mortality than it was in the districts where the disease was tenfold more fatal. But while the presence of this leaven seems to have, been universal throughout the districts of the mectropolis, the consequences' excited by its presence have* CHOLERA. 613 greatly varied in different localities; and independent of any hypothesis, it may now be stated, as the experience of two epidemics in London, that such local varieties of effect, grouped into masses for comparison, have been more nearly inverse to the elevation of soil in the affected districts than proportionate to any other general influence that we could measure. Thus, approaching London along the roads from the surrounding country, and descending through the successive regions succeeding each other in circles down to the waters of the polluted Thames, we see in the epidemic the people fall upon the right hand and upon the left, in numbers that increase in every circle, and express arithmetically the growing force of those physical influences on which the poison of cholera apparently depends for its powers of existence and development." In accepting this proposition we must qualify it by inserting the word relative before elevation. It is not the elevation above the sea level which conditions the affinity of a place to cholera, but its rise above the nearest water level. For example, it never was more deadly than upon the high table land at the source of the Euphrates, in 1822,1 when it destroyed a Persian army, killing 300 men out of a batallion of 1000, so that the rear of the line of march was strewn with dead bodies, as if the army had been all the way in action. The admission that the poison was pretty equally diffused over the plain of London, and only more fixed at different spots by local causes, throws great doubt upon 1 'Travels of Mr. Baillie Fraser. 614 CHOLERA. the assurances we frequently hear made by sanitary reformers, and which Dr. Southwood Smith is reported recently to have indulged in before a popular audience, that we shall be able eventually to avert these terrible scourges by a more careful attention to drainage. That something may be done to lessen the stay of the plague by removing the fostering impurities we admit; but so long as men select the banks of rivers to build cities upon-those natural highways of the world,-and so long as the sea shores-those margins of " creation's common" -are preferred to inland situations, so long must we expect that, in obedience to a law whose existence we cannot deny, but which to us is a mystery, this epidemic will return again and again, by its old road, to its old haunts, and at each recurrence mock all the efforts of all sanitary commissions, and only be restrained when the true prophylactic and specific remedies fortify all exposed to it against its malignant influence. We may perhaps hazard the observation, before leaving the question of the effects of elevation, that the greater salubrity of high elevations, in giving strength to nerve and muscle and immunity to many chronic diseases, as well as most epidemics, is a fact of greater importance now than formerly, for the substitution of artificial roads of iron for the natural water-courses will make us more and more independent of these dangerous places, and give to intercourse and commerce full sway, without taxing the health and longevity of all in any way dependent (and who is not?) upon their successful promotion. Reviewing all the committee has made out on the aetiology of cholera, we are struck by its extreme meagreness, and were little prepared for the concluding remark 616 CI-OLERA. the Divine character ascribed to the operation is due to our ignorance of its laws, a proposition, if it has any meaning, necessarily implying that the discovery of material laws leads to the rejection of the belief in the Divine causation of the universe. Failing to lay hold of the evil in the air, our philosophers applied themselves to an examination of the water, and we must all remember what a flourish of trumpets there was some time ago in the 'Times' and other organs of popular delusion, when the microscopists detected the imp of mischief in the form of vibriones swarming both in the water imbibed and in the choleraic discharges from the bowels. The discovery is thus quietly let down by the committee:-" With respect to the living animal and vegetable forms traced by Dr. Hassall through the whole series of waters, there seems no evidence that they, by their own action on the human body, could be productive of choleraic symptoms." At the same time there is ample evidence to prove that one of the most favorable conditions for encouraging the disease is the employment of water, contaminated with the filthy impurities of London, for domestic purposes. And if the fabulous importance once ascribed to this lead to an improved supply, it may find a place in history beside that other fable, which relates how a father told his sons that if they trenched the land he left them they would discover a treasure. They did so, and found, not gold, but improved fertility which was the treasure their provident but apparently lazy progenitor contemplated. There is no question agitated by the committee of greater importance, both theoretical and practical, than the connexion, if any, between cholera and diarrhoea, and CHOLERA. 623 withdrawn from the body. What can we expect from this dead blood? Certainly no secretions. Hence the suppression of the urine, and of the bile, and of all frecal matter, and hence, too, as a dead fluid it permeates the surfaces, both internal and external, in the former in profuse watery discharges from the bowels, in the latter as cold perspiration from the pasty skin. In the worst cases even the blood-globules are broken up, and then we find coloured sanguineous discharges from the bowels, erroneously looked upon as dysenteric, but wholly different, and the most fatal of all appearances as indicating the greatest decomposition of the blood. And this dead blood we believe also to be the cause of the cramps and the pains, by acting as an irritant poison on the nerves of motion and sensation. For the severity of the cramps is another index of the intensity of the attack. No wonder that the physician's art should so often prove unavailing in dealing with so frightful, intense, and rapid a poison, one more rapid and more intense than the venom of the most poisonous reptile! But how wonderful it is that we should have a remedy at all for the first stage of this terrible disease, and how marvellous that Hahnemann should have recognised at one glance the real nature of the malady, and directed us with confidence to the only remedy! And this, too, without having ever seen a single case of the disease, which he so thoroughly appreciated. What a contrast do his clear words of assurance and promise present to the confused mutterings of the present leaders of the medical hosts in the wilderness of doubt. And yet we are told by a writer in the Medical Timnes, who has of late been exercising his ingenuity in making mountains out of mole 624 CHOLERA. hills, that Hahnemann was all wrong in this, that Camphor is not homceopathic to cholera. If our modest teacher wishes to see his likeness in political life, we advise him to study the writings and speeches of a certain very pugnacious advocate of peace, who, after explaining that he considered the late war to be an infamous outrage against humanity, a sin and a crime in its origin and in its continuance, instead of insisting on its being given up, treated his audience to his views of the most effectual way of carrying on this flagrant wickedness. Thus our hostile instructor, after proving that homoeopathy is nonsense, objects to us for not being consequential in our nonsensical course of action. With all due deference to our anonymous adviser, as we preferred to leave the conduct of the war in the hands of those who believed in its justice, to making it over to the direction of a quaker meeting, so we shall continue to practise homoeopathy as recommended by Hahnemann, rather than follow the advice of one who sees only a lion in the way and rejects with the utmost contempt the aid of those who seek to prove to him that the lion he so dreads is nothing but an ass in the royal robe. All that now remains for us to do is to glance at the results of the different methods of treatment which occupy a separate report. A more complete burlesque upon the so-called numerical method of arriving at positive data in medicine, it has never been our lot to meet with. After the committee has told us " that the choleraic pestilence varies in the severity of the individual attacks from the degree of a trifling indisposition to that of a most deadly and intractable disease; that in one form it is fatal to 6, in another to 669 in every 1000, 626 CHOLERA. ing topic, whether the Opium was given in any unusually large doses. Fever is reported to have been prevalent in Paisley during the outbreak of cholera: but allowing certain weight to this latter cause for the large number of cases which passed from cholera into consecutive fever, it is still a question, as they were all treated with Calomel and Opium, whether the Opium was given in large doses. In the latter case, the result would seem to correspond with the large proportion of cases of consecutive fever in the metropolitan hospitals, in which the use of Opium combined with chalk appears to have been attended with like results." The meaning of this, stript of verbiage, is that Opium tends to produce consecutive fever. This inference of the committee is one we arrived at long ago, from observing the very small proportion of cholera cases treated homoeopathically in Edinburgh which passed into consecutive fever, in comparison to the large number with which such a termination in cases treated according to the directions of the Board of Health, then called the Sanitary Commission, which advised " twenty grains of opiate confection, for example, repeated every hour until the relaxation of the bowels ceased." We are disappointed at not finding more details of the effect of the Saline treatment recommended by Dr. Stevens. More fatal than 100 per cent. it could not be, and although we may suspect that the enthusiasm of the veteran pathologist has misled his judgment and induced him to over-colour the success of this mode of treatment, yet, making all such allowance, we cannot but wish to see a fair and extensive trial given to the use of the Salts he advises in cases of pronounced CHOLERA. 627 collapse, where all our efforts are so often unavailing. And we feel curious to know what was the result in Sweden of the following directions issued by the Board of Health of that country, and which seem to be certainly less dangerous than the Opium and brandy treatment patronised by the predecessors of the present committee: "General directions for the treatment of cholera founded on the experience of later times. "When an indisposition that gives warning of the new disease shows itself by weakness, giddiness, heaviness of the head, loss of appetite, swelling, or distentioni of the abdomen, nausea, and frequent diarrhoea, the patient ought without delay to place himself in a warm and soft bed, and cover himself well. He ought then immediately to take from two to three, at the most four, drops of the spirit ofcamphor diffused in a teaspoonful of sugared water, or on a bit of sugar, every five minutes. If after a few doses the patient falls into a perspiration, or if in this way the symptoms become milder, the doses are to be taken at longer intervals. If the symptoms become worse, or the drops be rejected as soon as taken, they must be given more frequently. If within two hours no important improvement takes place, and the wellknown symptoms of true cholera appear, then melt three good tablespoonfuls of common salt in a quart of warm water, and let the half of this be taken immediately till vomiting take place. After the stomach is emptied, a large mustard or horseradish poultice is to be applied to the pit of the stomach. This should be kept there till there arises a strong perspiration, and then a moderate 628 CHOLERA. teaspoonful of the carbonate of soda and a good tablespoonful of equal parts of vinegar and water is-to be given in a state of effervescence every twenty minutes. After three or four doses of the above effervescing medicines, whether the tendency-to vomiting be diminished or not, there must be given regularly each half hour, a Stevens' Saline Powder, in two or three tablespoonfuls of beef tea or oatmeal gruel. One of these powders is to be given every half hour, until the cholera symptoms have wholly and entirely disappeared, and even then the Saline powders are to be gradually discontinued, with more and more increased intervals." Afte some judicious observations upon the general management of the patient, the document concludes with the signatures of P. V. Afzelius, L. Hwasser, C. H. Berostrund, W. H. Romansson, G. C. Schultz, and P. J. Liedbeck. What were the results in Sweden of this plan of treating cholera? CHAPTER XIII. MEDICAL NOVELS.1 THE only feature common to these various and very dissimilar works of fiction is the one which brings them within the limits of our critical jurisdiction. They have each of them a Doctor for the hero of the piece. This is so new an honour for us that it naturally suggests the inquiry of whether there has been any change in the relation of medicine to fiction by which the two have been brought into a state of greater rapprochement than formerly, or whether it is a mere accidental drift upon the hat of the doctor of medicine of that incessant fall of novels which cease not summer or winter to descend upon the earth, tending to accumulate about the porches of the church, especially if of mediaeval architecture, and to overwhelm gentlemen who ride at sunset with a military air, but which hitherto has been rather dispersed than attracted by the sharp rattle of the doctor's carriage or the canter of the country surgeon's bony nag. To enable us to reply at all satisfactorily to this question, we must consider what the various kinds of fiction are, and we shall then perceive that while some of the multifarious productions will naturally eschew others will as naturally adopt, medicine as the appropriate magazine 1 'Doctor Antonio,' by the author of 'Lorenzo Beuoni' (G. Ruffini).'Two Years Ago,' by C. Kingsley.-' Fair Oaks,' by Max Lyle.-' Lucian Playfair,' by J. Mackern. MEDICAL NOVELS. 633 served; and a large number of modern novels, indeed probably the majority, are the moralities revived. While the special form of the morality-novel must depend on the genius or lack of genius of the writer, the subject will naturally be chosen in accordance with the requirements of the period. At one time it will be religious, if the public mind is interested in any ecclesiastical controversy, as it was some years ago; at another time it will be political like Coningsby: but at present neither church nor state politics are in the ascendant; on the contrary, had it not been for the large feeder from India the Tiimes was in risk of perishing of inanition, owing to the extraordinary apathy of the public about its own affairs. There is not at present a single political question which excites even the most moderate enthusiasm in the public mind, at least no question of internal policy. But sailors tell us that there is no time when more work is done than during a run across the Pacific Ocean, when, for weeks together, not a sail requires to be touched, for that then the men are all busy in putting the ship and all its tackle into order. So with the ship of state during this profound repose of the political elements, questions of social interest have for the first time risen to command public attention, and Young England has chosen for his motto " education and health." The consequences of this change are very curious. In the first place it annihilates political parties, for who can possibly deny the importance of either health or education? In the second place it advances into a new position the ministers of health and the body of teachers. This seems to be the reason of the appearance of the doctor as a hero. Had the moralities existed as plays instead of 636 MEDICAL NOVELS. shaggy trousers, and been startled by the print of the cannibal's foot. The fictionist who possesses this faculty may use it for effecting indirectly the objects aimed at by the two other orders of writers. He may produce a tale of wonders of surpassing interest, or he may make his characters represent his peculiar opinions, speculations, or beliefs, or he may employ his power of delineation in one particular direction so as to exhibit the vices and follies of his time. He will then be the satirist, and the satirist is the preacher in disguise, and so well disguised is he that one of our most popular and powerful writers of fiction has had to defend himself seriously from the charge of being immoral because all his characters were specimens of selfish, mean, and despicable human beings, whatever their social rank! As if it were possible for the mind to conceive of vice as vice without being in possession of the idea of virtue! and as if it were possible to depict meanness so that it gave rise to dislike or indignation in the mind of the beholder without stimulating into active exercise the nobler feelings on which this resentment depends. For the purposes of this highest class of novels, we consider the materials afforded by medical experience well suited. Either as actor or spectator the physician might be the central point of a most interesting and instructive fiction. If taken as an actor, he might be accepted as a type of a mind exposed to the most peculiar training, the results of which might be exhibited. He is placed in the most neutral, and, at the same time, the most instructed position of any class of men.' He 1 Sir T. Brown says, "I am of a constitution so general, that it consents and sympathises with all things. I have no antipathy, or rather no idio 638 MEDICAL NOVELS. speech and action, which the medical man who intends to rise in practice must feel or assume. The 'rough and ready' doctor, like the rough and ready soldier, is often the one most distinguished by fortune. Paul Glyn was not such. With his keen and delicate perceptions, he dared not practise the 'hit or miss' system of treatment; he saw too vividly all the remote possible consequences of the slightest error to risk anything willingly; he was not prepared to take many a random shot on the chance of one hitting the mark. And when he failed he could not carry off his failure with due professional imperturbability. Paul certainly was not born to be a doctor! He soon found he could not satisfy either his patients or himself; he had not their confidence, for he had not his own. He became more and more irresolute and selfmistrustful. Each failure prepared the way for others; with his character this was inevitable, for at each failure his high ideal and exaggerated self-reproach bore him down, and paralysed fresh exertion. And Paul began to dislike a profession which brought him into daily perplexities of judgment, into daily contact with problems he could not solve, and suffering he could not relieve. He began to experience that deep distaste of his circumstances-that weary restlessness, which assails a man who feels himself intellectually superior to his position, while practically, or in the opinion of others, he is unequal to it." This looks a picture from life. We at once recognise the quiet, unobtrusive, thoughtful, man of learning, who has been elbowed aside by the vulgar, loud, bustling, pushing practitioner, and who, settling in some eddy, watches the stream bearing others towards the prizes of 641.0 MEDICAL NOVELS. matters and ready tact in devising expedients for putting wrong right in Dr. Thurnall, the hero of ' Two Years Ago,' by Mr. Kingsley. There is also a much richer field of incidents invented for the display of this medical faculty. But Mr. Kingsley in this, as in most of his other novels, uses his characters too manifestly as masks through which to utter his own sentiments. The voice is still the voice of Jacob, however hairy his hands may be. So that, although, with the instinct of genius he has represented a good deal of the ready-handed doctor in Thurnall, yet the character, as a whole, is altogether an unfit representation of the true medical man, and indeed Mr. Kingsley seems quite aware of it, for reserving the prize-a lord's sister-for a long-skirted, young, lilyhanded, intoning, clergyman, who comes out on the high church side and is converted to the opposite by the cholera in the course of a few pages, he marries his medical hero to a mad Methodist teacher,-and it is a very suitable match. The admirable story of' Dr. Antonio' derives its interest from the excellence of its portraiture of character. The hero is a doctor, because it suited the purpose of the author to represent him in the variety of situations natural to such a calling at the period and country in which the scene is laid. But he is not a medical hero; he is a chivalrous Italian gentleman who moves with native grace, power, and dignity through a variety of events of domestic and political interest. He is in his nature a genuine hero, but the doctorship is entirely adventitious. His profession is made subservient first to love, and then to politics. CHAPTER XIV. SAMUEL BROWN. THosE who knew him, and those who did not, wvill be equally disappointed by every biography, be it full or be it brief, of Samuel Brown. No description can justify to the one, or explain to the other, the admiration he excited. The reason is not far to seek. Biography is a branch of history, and history occupies itself with actualities and not with possibilities: it is the chronicle of success: it leaves to the orator and the poet to build a shrine to the nameless demigods, out of whose fall the hero rises to glory and a deathless name. While the intellect bows submissive to this inexorable decree of fate, and concedes that history must follow the career of deeds without pausing to tell of efforts, yet there is a craving in the depths of our being to have some memento of those who have exercised a powerful influence upon us: some record of the talisman that bound by its spell so many and such various characters. That Samuel Brown possessed this talisman, will appear from the merest outline of the story of his life. He was born at Haddington, the 23d February, 18 17. His father was a small merchant, the son of a dissenting minister, John Brown, the author of a well known commentary on the Bible which bears his name. He was SAMUEL BROWN. 647 talents. To the latter some of the most eminent men of the day bore emphatic testimony. Archdeacon Hare, the author of 'The Victory of Faith,' 'Guesses at Truth,' &c., thus writes to him. "There is a philosophical power of looking into the heart of things and discerning their inmost relations, which is the highest faculty for all speculation, whether its object be the outer world, or the moral and spiritual nature of man... The writings of yours with which I am acquainted, have seemed to me to betoken that you do possess the power of philosophic intuition in a degree in which it is possessed by very few Britons of our age." Thomas Carlyle writes, "I can at all times with great readiness testify that I have found in him a man of vivid penetrating, high aiming, hopeful nature; full of ardour, of discernment, and veracity; a singular acuteness as well as vigour of intelligence, prompt invention, clearness, swift precision, nay, brilliancy and general felicity of utterance,-the elements in short of a truly gifted man, to whom scientific or other triumphs, if circumstances proved not too unfavorable, were very possible, were very probable." Thus backed by Carlyle, Hare, Jeffrey, Hamilton, Chalmers, and many more celebrities, Samuel Brown had very nearly got the chair, and it was the opinion of his friends that if he had rested his title on his general and scientific capabilities, and not upon his discoveries, he would have succeeded. The contest was keen, and he retired, although beaten, with high honours. The following May, 1844, he thus wrote of it to a friend. " My thoughts and feelings about Chalmers noble letter, and Macdougall's1 noble exertions, I shall SProfessor of Moral Philosophy in the University of Edinburgh. 648 SAMUEL BROWN. tell you better than I could put them down on paper. I tell you I would not this poor day give that letter of our Scottish hero of 1800-50; that other of Carlyle's, the British chief of the same period; that of Emerson, the prophet of young America; the unsought enthusiasm of Macdougall, the man of Edinbro' of this year; the indignation of Sir William Hamilton; the erudition of Edinburgh and Oxford in one extravagant, magnificent head; the approving hope of Hare, the apostle of faith, illustrated by understanding, in the majestic church of England; the life of love given me without reserve by Archibald Craig, the acute and fervid angel of my studious toils; the kindly admiration of your well-beloved self, Drysdale, Ross, Simpson, Giraud, and a few more, with Ruffini, the still centre figure of the blessed group; and last, far from least, the judicious smile of our keen and graceful Jeffrey', for an earldom and broad acres to boot, not to say a paltry chair even in the alma mater of my yearning youth." This was a proud moment; by sheer talent he had, at the age of 26 years, won for himself the interest and admiration of the foremost men of his day. We look upon it as the culminating point of his career. Up to this time he was the heir apparent of the crown of science; he claimed the throne as his due; had his claims been allowed he would have reigned right royally, for he was of a glorious nature; but his claims were not admitted, they were protested against by the whole hierarchy of chemistry, he was looked upon by them as a pretender, and his life was wasted away in one long miserable effort to vindicate what he to the last maintained to be his legitimate position. SOf the 'Edinburgh Review.' SAMUEL BROWN. 653 "We shall seldom meet," he wrote to a friend, cc"one another now. Let each see that the other has grown when we do meet. To be stronger and freer, in a word, to be manlier! and manlier every year be now the common object of our unenvious emulation. I challenge you to the generous combat." Let us accept the noble challenge, and expect the meeting, humbly committing the time and place to Him who is the beginning and end of the career of all His creatures. To Him, too, let us commend the faithful partner of poor Samuel Brown, who did all that woman could to mitigate the unutterable sorrows and sufferings of his long, long death.
