CUMBERNAULD CO., PUBLISHERS 2001 LINCOLN STREET 1896 7 COPYRIGHT, 1896, BY HERMAN PARTSCH ALL RIGHTS RESERVED \ - -;- TO MY SON AND DAUGHTER, HERMAN DIXON AND CONSTANCE MARY, THIS BOOK IS AFFECTIONATELY DEDICATED. PREFACE. IN writing this book my object has been to put on record certain facts that I have learned during the last twenty-five years on topics com- prehended under the title of dyspepsia, and to make those facts available for the use and relief of those whom they most cerncern. Dyspepsia is the mother of more ills than it has ever received credit for, and the literature of medicine has not yet offered the sufferer any scientific or practical means of relief; which facts constitute my apology for offering this book to those who suffer in any manner from any of the ills of indigestion. I hold little or nothing in common with the views generally prevailing on disorders of diges- tion. My conclusions will be best judged by the results to which they lead in my practice, namely, the same certainty of easy success in curing every case undertaken as that with which a builder undertakes the construction of a house, (v) VI PREFACE. and that regardless of the previous duration of the case. I have spared no pains in writing and explain- ing just what in my judgment the dyspeptic needs to know. I have taken no trouble, how- ever, as to the mechanical arrangement of my material. The index has been omitted as un- necessary in this instance, and the table of con- tents has been left in the utmost state of brevity. I have said little of dyspepsia itself, but I have said more of its causes. There are three great causes of dyspepsia, and the only rational clas- sification of dyspeptics must be made with refer- ence to those causes. Each cause has a distinct essay separately devoted to its discussion, and, towards the close of it, the matters of prevention and cure are also briefly but sufficiently attended to. In the essay on Energy-Diversion Dyspepsia, I have pre- sented numerous extracts from the biographies of Charles Darwin and Thomas Carlyle, for the purpose of sustaining my own argument with evidence from these famous sufferers. My ex- tracts from Darwin and Carlyle are, perhaps, much more numerous than necessary for my PREFACE. vn purpose. But they sustain my views so much the better, and they serve the purposes of instruction more efficiently than a briefer selec- tion would. And, above all, these collections of biographic extracts relating to the illnesses of these men, are very well worth preservation in just the form in which I have arranged them. Each of the divisions of the second essay has its sections independently numbered, while in the first and third essays the sections are con- secutively numbered through the two divisions into which each essay is divided.

WE are concerned first with a very simple, well-known and important principle, upon which will depend our understanding of all that needs to be said of the class of dyspeptics that will be considered in this essay. A due consideration of this principle, and a proper understanding of its importance, will easily follow a careful show- ing of its application in the determination of the cause, the cure and the prevention of dyspepsia in a large class of cases. I can proceed to best advantage by citing from the record on hand a " chronic " case of dyspepsia, in which an under- standing of the principle clearly led to cause, cure and subsequent prevention of the illness to date a period of eight years. 2. I purposely select an alleged critical case, and at the same time one of the very easiest cases in which to secure a complete, speedy and lasting recovery. The critical element of this case, whom I will call Modero, had its existence only in the minds, as usual, of Modero himself, his friends and his physicians. That the case (9) 10 REPETITION DYSPEPSIA. was not at all critical when understood and properly conducted was proven by the simplic- ity and the complete success of the treatment by which Modero got entirely well. 3. The particulars of the case are as follows: On the Pacific Mail Steamship Granada, on the twenty-eighth day of March, 1888, I was approached by Modero on the subject of his own illness. He was an Italian, fifty-three years of age, seafaring man until about 1878, since then capitalist residing in San Francisco. And the use of him, as an example for purposes of demonstration, is my compensation for the serv- ices rendered in the case. At this time Modero weighed one hundred and fifty pounds. Six months previously his weight had been two hun- dred and ten pounds. During the autumn of 1887, Modero was sick in San Francisco and at various times in the care of three doctors. Failing to restore him to health, the doctors advised Modero to make a voyage to Central America; and he sailed in November. His health was not improved by the voyage, nor by his stay in San Salvador, where his case was attempted by a fourth phy- sician. During the four and one-half months since leaving San Francisco, he had grown steadily worse, and was gradually losing weight, and while in San Salvador he became so ill and ON THE: CAUSES. n helpless as to require the assistance of his wife to get him back to San Francisco. She was telegraphed for, and in the course of time arrived, and was bringing him home when I met him on the Granada. Modero had been informed by his doctors that his illness consisted of dyspepsia, so he told me ; and such proved to be the case. At the time of our meeting he had been ill about six months, and during the last four of these months, he had suffered constant pain within, and had had constant diarrhea. During the same four months, he was decidedly sick, had no appetite, and ate very little. He had lost sixty pounds of his weight and had yet one hundred and fifty pounds left. The loss representing two- sevenths of his normal weight. 4. Seeing that I was interested in his case, and knowing that at the rapid rate of his decline he could not last many weeks longer, he said he would make me a "handsome present " if I cured him. I undertook the study and conduct of his case on the 28th of March, 1888. It soon appeared that the case was indigestion and nothing more. Up to April 5 improvement had been gradual, certain and considerable, excepting one very slight relapse. On April 5 I promised Modero complete recovery. On April 9 he disembarked at San Francisco sound and well. He soon regained his normal weight, and has 12 REPETITION DYSPEPSIA. been well during the eight years since that time. (The "handsome present" did not materialize.) Modem's case has been selected as an example, because it was one of those extreme cases which are likely to result fatally. And I have cited his case in detail to show the easy practicability of speedy, complete and lasting recovery. And this case has been selected also because it sup- plies a very plain and clear instance of the operation of the principle which leads us to the means of effectually curing and preventing a very large share of the ills of indigestion, regardless of previous duration or treatment of the cases. 5. At the time I undertook Modero's case he was subsisting exclusively on arrowroot, sugar and water, and had been so living for some weeks. This was because any other articles of food, in the opinions of his physicians and him- self, aggravated his illness. No further exami- nation was made than so far as to elicit the manner of his . living then, and back to the inception of his illness. And nothing further was necessary to be known. The manner of Modero's living contained an error which was quite sufficient to account for his illness. The very simple and elusive little error in Modero's living consisted of eating sugar, under the cir- cumstances that he ate it. This will be made clearer later on. ON THE CAUSES. 13 The treatment of the case consisted in de- priving the patient of sugar, as such, alto- gether. The issuing, limiting and varying his meals were all non-essential and unimportant details of the management of the case. The sugar was stopped, his pain ceased, and so did his diarrhea. He was then in an advanced stage of starvation, and had to be fed with care and with regard for the temptation to overeating under such circumstances. During the first two days, he ate and drank at intervals of two to three hours. No item of food was repeated on the same day. The quantity of food or drink at each time was small during these two days, and was increased thereafter in proportion to the improvement of the patient in general and his stomach in particular. The rule observed referred not so much to what he ate, but required that the meal should consist only of a single item of food for two days, and that thereafter the transition to two and three or more items be gradual. The quantities taken at each time were to be very small at first, not to exceed a tablespoonful during the first two days, and the increase to be very gradual. It was also required that all foods be fresh, or freshly from the stove. Modero rapidly made a recovery that was com- plete and enduring. 6. I gladly let Modero pass now with only 14 REPETITION DYSPEPSIA. some necessary references to his case for the purpose of demonstrating the application of the principle by which his illness and recovery and subsequent immunity from the ills of indigestion are accounted for. Modero's case is typical of a large class of dyspeptic cases, and I pass now from matters concerning Modero in particular, to matters concerning the class of cases in gen- eral. And when any point in Modero's case is again alluded to it will be because that point is applicable to the class of cases in general. 7. There are a few articles of food which, in the subsistence of many persons, occur one, two or several of them, three times a day. These are almost certain to be sugar, milk and butter; one, two, or all three in an individual case. In speaking of sugar, milk and butter as foods, we must distinguish between these materials used as such and used in cooking as a constituent of a complex something else. In referring to sugar, milk and butter as under some circumstances causes of indigestion, I mean that sugar, milk and butter which are added to foods after cook- ing the sugar from the sugar bowl, the milk from the milk pitcher, the butter from the butter dish. Just as the error in his living caused the illness of Modero and was quite competent to cause his death, so the error in another dyspeptic's case may be the use of milk, ON THE CAUSES. 15 or butter, or any other item of food used under similar circumstances. And in some cases two or more such errors are combined. 8. The animal mechanism, with all its appara- tuses and with all its processes, mechanical, physical, chemical, nervous, and even mental, is so nearly automatic that one is strongly tempted to believe it is quite so.* It appears that any proc- ess, mechanical, physical, chemical, or nervous, takes place only in response to some stimulus. A stimulus is related to the occurrences with which it is associated very much as a railway engineer is related to the engine and train. He causes the train to move, but the cause of the train's movement does not lie in the engineer. The content of the bowel serves as the stimulus in response to which the bowel sends it along, in just the same way as water is sent along a horse's gullet, as may be observed when he is drinking. Every physiological event depends, not only upon its cause, but also upon some other event which serves as the stimulus in response to which its cause is set in operation and its occurrence takes place. The presence of food in the stomach serves as the stimulus in response to which the appropriate processes of digestion take place. But it happens sometimes *See Huxley's "On the Hypothesis that Animals are Automata, and its History." 1 6 REPETITION DYSPEPSIA. that an event which ordinarily serves as a stimulus will fail to serve as such. And it is the circumstances and conditions of such failure the reasons for it that are very usefully inter- esting to the class of dyspeptics whom this essay specially concerns. Let us first observe some instances showing when an event will, and when it will not, serve as a stimulus. 9. The sounds, scenes and meaning of a well- performed opera, or any theatrical play, taken as a complex whole, serve as a stimulus in re- sponse to which a correspondingly complex set of pleasing sensations merges into the con- sciousness of the person attending. If a person attend repeated performances of the same play in close succession, the performance will lose its efficiency as a stimulus in proportion to the extent that the person's attendance on the play is repeated. The set of pleasing sensations, that merged into consciousness at the first attendance, becomes less and less pleasing, and may sooner or later become tiresome and even disgusting. When Mark Twain heard "for the first time the famous Alpine jodel in its own native wilds, it was very pleasant and inspiriting to hear." Twain says: "Now the jodler appeared, a shepherd boy of sixteen, and in our gladness and gratitude we gave him a franc to jodel some more. So he jodeled, and we listened. We ON THE CAUSES. l^ moved on, presently, and he generously jodeled us out of sight. After about fifteen minutes we came across another shepherd boy, who was jodling, and gave him half a france to keep it up. He also jodeled us out of sight. After that, we found a jodler every ten minutes; we gave the first one eight cents, the second one six cents, the third one four, the fourth one a penny, contrib- uting nothing to numbers five, six, and seven, and during the remainder of the day hired the rest of the jodlers, at a franc apiece, not to jodel any more. There is somewhat too much of this jodling in the Alps." * So it is, more or less, with sights, sounds, recitals. Cheerfully paying for them under some circumstances, we would as willingly pay to be excused from them under some other cir- cumstances. But we should bear in mind that any event of this kind loses its efficiency as a stimulus only when its repetition exceeds a certain degree of frequency. A drug, a medicine, a poison, a beverage, a food, each, upon entering the animal body, serves as a stimulus in response to which some physiological event, or series of events, follows. And each stimulus of this, as of any other kind, has its peculiar period; a time short of which it should not be repeated, if it is *And of the whistling nuisance everywhere in the United States of America. 2 1 8 REPETITION DYSPEPSIA. expected to retain its efficiency as a stimulus. That drugs, medicines, and especially poisons, by frequent or continued injestion, cease to be followed by the effects that attended their first ingestion, is familiar to every observer. 10. Within ourselves a cause does not seem to operate to produce an effect, except in response to some event as a stimulus. The importance of the stimulating event therefore becomes plain; so does its relation to the cause and effect with which it is associated. Certain effects within us must take place in order to maintain health and vigor. But some such effects sometimes fail to occur, because the stimulating event fails to serve as a stimulus. Illness then to some extent is the result. Water or food in the horse's gullet serves as the stimulus in response to which the gullet moves that food or water along into the stomach. The material in the intestine serves as a stimulus in response to which the intestine moves its content along. Food in the stomach serves as a stimulus in response to which that food is digested. And each event in the process of digestion serves as the stimulus in response to which the next event in the regular order of succession takes place. Attempting to subsist upon meals precisely alike three times a day would be imposing upon the stomach and in- testine the same stimulus repeatedly. And the ON THK CAUSES. 19 time soon comes when that stimulus ceases to serve as such, and the stomach and intestine do not respond. Whatever else occurs during digestion, one thing is certain, a preliminary part of the process consists in so sterilizing the material that it does not rot. If this preliminary sterilization fails to take place, the content of the stomach, and of the intestine to some extent, will be rotting within fifteen to twenty minutes from the time it is taken in; or it will be rotting immediately if any part of it is stale, or infected, which is very frequently the case with sugar, milk, butter and cold dishes in general during warm weather. II. So it is that indigestion may and does result from monotony of diet. And to this cause a large share of all the ills of indigestion is attributable. Indigestion means just what it says. The foods are more or less imperfectly or incompletely digested; that is all. Food can not long remain what it is at the time of entering the stomach; because it is in the presence of heat, moisture and air. In plain English, if the food is not soon digested, it soon rots. More elegantly stated, it ferments. And by the proc- esses of rotting or fermentation the food only undergoes changes. A knowledge of the nature of these changes can not aid the dyspeptic toward recovery, and is therefore omitted here. 20 REPETITION DYSPEPSIA. But I want my dyspeptic readers to have a practically sufficient idea of the extent and radi- cal character of these changes. So I will say that the rotting, for example, of meat or eggs in the stomach changes these materials as much, and to an equal extent, as when they rot anywhere else. And as the mass of food in the digestive canal is often a very heterogeneous conglomera- tion of good things which it may be a pleasure to receive, it is capable of conversion to an equally heterogeneous conglomeration of very bad things, as a further examination will show. I need not go far into the details of the changes and the resulting products, but I must go into the sub- ject far enough to show the sources and causes of pain in indigestion, and what useful intelli- gence should be derived from their occurrence. 12. Among the constituents of the resulting rotted mass are some that are poisonous and sufficient to account for the illness of the person in whose digestive canal the rotting takes place. Some of the products are gaseous and account for the eructations, the bloating, and sometimes painful distension of the stomach and bowels. Some of the products, gaseous and liquid, are irritating and cause pain by irritation. This irri- tating quality is understood by the sufferer who has gaseous eructations, for they are often pain- fully irritating. So we see that the special pains ON THE CAUSES. 21 of indigestion are due to irritation and distension. And the general illness of the sufferer is due, firstly to the general demoralizing effects of the pain; secondly, to absorption into his circulation of some part of some of the poisonous products of decomposition which make him ill as other poisons would. 13. According to nature's rule, the food enter- ing the stomach serves as the stimulus in response to which digestion begins in the stomach and ends down in the bowel. But in the case of an exception to the rule the food does not serve as the usual stimulus, and it is not digested, but is decomposed into an utterly different mess, which differs from the original as much as a rotten egg differs from a fresh one. This converted mess serves as a stimulus in response to which a series of events takes place quite different from those of digestion. And just what this series of events is, is immaterial to my purpose. Some points, however, in this connection must not be over- looked. 14. Sometimes indigestion is accompanied or followed by diarrhea, and the two are so asso- ciated that when the indigestion is cured the diarrhea is cured also. The two were so asso- ciated in the case of Modero. This was what made his case so critical and cost him in a short time two-sevenths of his weight. When Modero's 22 REPETITION DYSPEPSIA. sugar was stopped, his indigestion was stopped, so was his consequent illness and the resulting diarrhea. The relation of diarrhea to indi- gestion is one of the details of our subject that is worth knowing well and remembering. This diarrhea is not amenable to medical treatment. Doctors always give medicine for it, and often it is cured, but not by the medicine. The cure, apparently by medicine, results as follows: The patient is given an opiate to the extent that he is saturated with the poison, and is made sick, and his appetite suspended to such an extent that he omits much of his usual food; and with the omitted portion is something that rotted and set up decomposing changes in everything else he ate, as one rotting potato infects another. What causes the diarrhea is one or more of the prod- ucts of decomposition serving as purgatives in the same way as purgative drugs do. So we see that diarrhea is one event that may occur in response to the decomposed mass as a stimulus. 15. Sometimes another event, in response to the decomposing mass as a stimulus, is nausea; and this is sometimes still further attended by retching. Of this I need only say that some one or more constituents of the decomposition products serve as stimuli in response to which nausea and retching occur. Whatever this prod- uct, or combination of products, is, its action is ON THE CAUSES. 23 just like that of a drug which in the stomach or circulation would serve to cause a like result. 1 6. Nausea and retching are caused sometimes in connection with cases of indigestion, in a very different way from the one just cited. Nausea and retching do not always attend indigestion, and when they do, it may not necessarily be attributable to any nauseating constituent of the decomposed food. Nausea and retching are sometimes due to the alarm and anxiety caused by the pain that attends indigestion and rotting of food in the digestive canal, just as they are often due to alarm and anxiety attending other pains or painful manifestations of the person him- self, or the sight or citation of painful manifesta- tions on the part of others with whom one is in sympathy. 17. Retching is not understood; and as it is so often and so intimately associated with indi- gestion, it would seem to me improper to omit a practical explanation of it. Retching is of such alarming aspect to most persons that it becomes very desirable and useful to know how to treat it rationally. I will, therefore, for general rea- sons, explain the process, its purpose, and how the knowledge of it may be utilized in the con- duct of cases in which retching occurs. An acceptable explanation of retching under all circumstances was given in my book on Sea- 24 REPETITION DYSPEPSIA. sickness, sections 84 to 92. The same explana- tion in these pages will be given more briefly. 1 8. Whether caused by drug or decomposition product, or by anxiety or alarm concerning one's self, or incidental to sympathy with others in pain, the first inferable step in the short series of events which ends in retching, is a disturbance of the circulation of the blood, preceding which is a disturbance of the heart and blood-vessels, and back of this again is a disturbance in the work- ing of the system of nerves (the vaso-nervous system) that attends and regulates the operation of the heart and blood-vessels, and therefore the circulation of the blood. And back of this nervous disturbance is the first cause of the retching. This first cause is exceedingly varia- ble and assumes many forms. Any reader knows from what great variety of first causes retching may proceed. This simply means that the vaso- nervous system is a very sensitive and delicate department of our anatomy, and is subject to disturbance from many causes. 19. One detail of the function of the vaso- nervous system is to maintain a proper degree of blood pressure, which varies in accordance with local and general influences and needs. This variable degree of blood pressure is maintained by the elastic contractile force of the blood-vessel under the influence of the vaso-nerves. Now ON THE CAUSES. 25 any event which disturbs this set of nerves must by consequence disturb the circulation of the blood. Whatever the whole effect of a disturb- ance of the circulation may be, I neither know, nor care to inquire; but, one effect that can, beyond all doubt, be inferred, and may even be observed, is arterial relaxation, or the relaxation of arterial tension. Vessels traversing bones can relax but little, if at all. Vessels traversing mus- cular tissue cannot relax a great deal on account of outside support. Vessels in the abdominal cavity, traversing the mesentery, omentum, and walls of the stomach and intestine, have the least outside support, and therefore can relax a great deal. When the vaso-nervous system is functionally disturbed, the vessel walls and arte- rial tension are relaxed, and by virtue of such relaxation the vessels in the abdominal cavity become distended whenever the amount of blood in them and proper to them is increased by addi- tional quantities settling down from higher levels. 20. Any considerable increase in a short time of the quantity of blood in the abdominal cavity, when due to arterial relaxation, must be accom- panied by a diminution of the quantity of blood in vessels at higher levels. And such diminution must under such circumstances occur in the brain whenever the head is in any position above the level of the abdominal cavity, particularly in 26 REPETITION DYSPEPSIA. the sitting and standing positions. In the re- cumbent position without a pillow, general arte- rial relaxation may occur from any cause which will functionally disturb the vaso-nervous system, and there will occur no physiological violence that the subject will be conscious of. But in the recumbent position with the head elevated on a pillow, and much more so in the sitting and standing positions, a functional disturbance of the vaso-nervous system is followed by vascular relaxation; next by an excess of blood in the abdominal vessels and a corresponding deficiency of blood in the brain. This mechanical deficiency of blood in the brain is the one and only serious result of vascular relaxation ; and so serious is it that nature does not allow it to continue more than a very few seconds. Nausea is the sensa- tion attending this state of things. 21. The process by which nature promptly corrects a mechanical deficiency of blood in the brain is called retching or vomiting. It should only be called retching. The regurgitation of food is not essential to the process, and in some persons never occurs. Retching goes on rather more persistently when there is no food in the stomach, and sometimes continues persistently long after the stomach has been emptied, show- ing that the emptying of the stomach is not the object of the process. The stomach has nothing ON THE CAUSES. 27 to do with retching. It is only passively impli- cated, when at all, in a way that is purely incidental. The process of retching is entirely involuntary, and consists essentially of inflation of the lungs, closure of the glottis, and simulta- neous contraction of those muscles of the chest and abdomen that will cause compression of their contents. The pressure thus effected, acting upon the blood-vessels in the chest and abdomen, and therefore upon the blood in them, forces a part of that blood upwards into the vessels of the head. This flooding of the brain with blood is always the object of retching. And retching never occurs except in response to a condition of things in which there is either an actual mechanical deficiency of blood in the brain, or the blood is very poor in nutritive material. 22. Retching, then, is to be avoided by avoid- ing its first causes. This, however, is not always practicable. But, being subjected to the opera- tion of any such first cause of disturbance of the circulation, it is generally practicable to lie down without a pillow, or only a thin pillow, and by thus keeping the head at no higher level than the abdominal cavity, maintain a position which does not permit the occurrence of a deficiency in the brain by gravitation of blood to the relaxed vessels of the abdomen. Thus we can success- fully either prevent or correct a mechanical defi- 28 REPETITION TYSPEPSIA. ciency of blood in the brain and its correspond- ing sensation of nausea, and the retching by which nature floods the brain with blood. The retching that is due to poverty of blood, in respect of nutritive material, will not altogether subside in the recumbent position, although it becomes less violent. Retching from such cause must be treated by recumbent position and satu- rating the blood with nutritive material, by eating and drinking, a little at a time and often. 23. To complete my explanation, I should speak of fainting, although this phenomenon rarely keeps company with the ills of indigestion. In fainting we have the most extreme degree of what I have explained. A disturbance of the circulation, relaxation of the abdominal vessels, diminution of the brain's share of blood, all so sudden and extensive that not enough blood is left in the brain for the performance of its func- tions. For this reason the brain's part of the function of retching can not be performed. But a more prompt and effective procedure takes place. The person so falls, if allowed to, that the head is brought to the same level with the abdomen. The brain then soon gets its share of blood, and the fainting spell is soon ended. 24. The nutritive materials of the foods we digest find their way into the circulating blood, by and from which they are distributed to vari- ON THE CAUSES. 29 ous localities for the purposes of structure, and retrograde change for the production of heat and muscular, nervous, mental, and vital energies. The blood is rich or poor in respect of nutritive materials, according to whether we are well fed or ill fed, or have recently or not recently eaten. The sensation of hunger is present with, and is proportional to, the poverty of blood at any time during health. Hunger is the stimulus in re- sponse to which we eat. Of the foods that are available, we observe that there are some that we want and some that we do not want. The indi- vidual also observes in his experience that some foods have been transposed from the class not wanted to the class wanted and vice versa. Many an individual also observes in his own experience some one or more foods which he wants but which he says do not agree with him, and that some or all of these foods have agreed with him at some former time. He may also have found that some foods agree or disagree according to the circumstances under which he takes them. One with such experience is "pre- disposed" to suffer from indigestion, but it would be more strictly true to say he is disposed to err in his method of subsistence. 25. In this land of plenty in great variety, in this "age of cans," when the products of each particular season are preserved for use through- 30 REPETITION DYSPEPSIA. out the year, we choose to make our board of what we like; and choose from a multitude of materials each as good as the other so far as our needs are concerned. Why we select from among food materials, why we habitually employ some and habitually exclude others, may be due to convenience or accidental habit or both. The man who never, directly nor indirectly, has trouble with his digestive apparatus, eats and drinks in a manner proper to his individual self. His intuition guides him perfectly. The man to whom the ills of indigestion are personally un- known, shows by his example how easy it is to enjoy perfect immunity from such ills. The dyspeptic, however, can not generally follow the example of such a one, and enjoy equally good health, and thereby hangs a question which, with a few others, constitutes the subject upon which both dyspeptics and those who undertake to cure them have long sought light. On selec- tion of foods, on natural preferences and unnat- ural or acquired preferences, I might attempt some discussion. But nothing practical would be gained by doing so. Any definition as to what selection scientifically is or is not, would cut no figure in the relief of a suffering dyspeptic. Therefore I am glad to pass on, even without a definition. Selection there is, and it concerns the dyspeptic to an extent and in a way that he has not been aware of. ON THE CAUSES. 31 26. The power of selecting foods has its ori- gin in nervous tissue, that tissue which is the material concomitant of mind not the mind, but simply mind. Mental phenomena have their origin in nervous tissue, but not exclusively within the human skull. Nor is mind the exclu- sive property of man, nor even of the higher vertebrate animals. Animals very low in the scale of nervous development have mind enough, by whatever other name it may be called, to select materials suitable for their subsistence, and to reject what is unsuitable. There is some reason for concluding that, in the case of man, the phe- nomena of mind do not belong exclusively within the skull. And there are circumstances which seem to indicate that he has mind in the abdominal cavity, in that nervous tissue which controls the stomach. Enough mind to serve well the purposes of the stomach in accept- ing and operating upon suitable foods imposed upon it, and in letting strictly alone such foods as are not suitable. And the stomach does let foods severely alone under some circumstances. The selection of an item of food, we are accus- tomed to think, emanates exclusively from some particular locality in the brain; and it emanates far enough from its source to merge into con- sciousness. I will designate and afterwards refer to this as the conscious selection, to distin- 32 REPETITION DYSPEPSIA. guish it from an unconscious power of selection and rejection which is assumed to have its origin in the nervous tissue controlling the digestive apparatus. 27. For assuming that there is a power of selection residing in the nervous tissue of the stomach, and separately and independently of the power of selection residing in the brain, reasons will appear which I believe will leave little doubt as to the propriety of the assumption. But no such reasons could be apparent, it seems to me, if the stomach's choice always coincided with the head'schoice. It does generally so coincide. The exceptional cases, cases in which head and stom- ach differ as to choice, furnish us with some instruction that is very important to dyspeptics. In the matter of selection there must be harmony between head and stomach, or else there is dys- pepsia. We all know what it is to like or dislike particular articles of food. And we know what it is to dislike foods at first and then like them later, and to like them at first and dislike them later. The head and stomach have each and separately the power of selection and rejection in respect of an article of food. 28.

It also sometimes hap- pens that persons will suffer from indigestion from the violent mental exertion involved, for 100 ENERGY-DIVERSION DYSPEPSIA. example, in an angry dispute just after eating heartily. Generally in such cases some offense to the person serves as an objective stimulus in response to which he automatically makes, or attempts to make, with all his mental might, much effort of the defensive or retributive kind. 6. Evidently indigestion does not in every- body's case follow upon the most violent and prolonged efforts of body or mind. So whether it does or not must depend upon some circum- stances or conditions. These we will not attempt to inquire into, except to observe what on super- ficial inspection appears to serve as an explana- tion of the distinction between cases in which indigestion occurs and cases in which, under like circumstances, it does not occur. The indiges- tion, in such cases as those I have cited, appears not to occur in vigorous young persons, nor in older persons who have at least a moderate share of fat in their structure. It appears to occur in lean persons of almost any age, especially those who employ their minds with all their might to the fullest extent of their time.* *The fat which an animal carries furnishes force for the continuation of work after the supply of force-yielding food last taken in has been exhausted. Its fat is the fuel and furnishes the force that carries the migrating bird many hundreds of miles without food or rest. ARGUMENT. 101 7. I have considered the digestive force as a part of the energy which is used up in the physical maintenance of the animal body. This energy of repair or maintenance, or, as we may call it, the running energy, is generally reserved for that purpose alone; but we have the power of diverting it from its proper function, at times when we have exhausted our supply of working energy and are yet tempted, contrary to our inclinations, to continue longer at work. It is not difficult to observe, sometimes in cases of overworked persons, that the details of repair and maintenance have been neglected in their animal economy. It is particularly easy to ob- serve, as in the examples cited, that digestion becomes inefficient or stops entirely during mental or bodily efforts that are extraordinary and prolonged. The examples cited show that such excessive demand can be made upon the working energy as will soon exhaust the supply, and cause the diversion of the digestive energy A good case, for example, is that of the plover which migrates regularly between the Hawaiian Islands and California, and must fly at least two thousand miles with- out food or rest. The fat which an animal carries is in the strictest sense a storage battery. It is never the lean man that can make such prolonged and vigorous mental effort as is involved in long argu- ments before juries and before legislative bodies. 102 ENERGY-DIVERSION DYSPEPSIA. from its proper function to be consumed for work also. 8. All the several animal energies are corre- lated, and are transmutable. Observing the various organs of the digestive apparatus, we find muscular tissues and nervous tissues, and we infer that muscular energy and nervous en- ergy are involved in the processes of digestion. But these two forms of energy are correlated and mutually transmutable. And the testimony of many a dyspeptic goes to show that during meals, and just after eating, actual mental work is done at the expense of energy that would otherwise be employed in the processes of digestion. The famous dyspeptic, Thomas Carlyle, recorded many instances, in his own experience, of suffer- ing severely for talking during and immediately after dinners. And Shakespeare knew this when he wrote, ''Unquiet meals make ill digestions."* Carlyle's talk was of the high-priced quality, so to speak. His talk at a dinner party cost him his best mental energy, and generally cost him all he had at the time. By almost incessant men- tal effort, Carlyle kept his stock of working energy almost constantly reduced to its lowest limit; so that for several hours' talk, begun with dinner and ending after it, he exhausted not only *Lady Abbess, in "Comedy of Errors." ARGUMENT. IO3 his working energy, but borrowed, also, too heav- ily of the energy which runs the apparatus of digestion, after which he was able to write: "Last night, greatly against wont, I went out to dine. . . . A dull evening, not worth awakening for at four in the morning, with the dance of all the devils round you." That the digestive en- ergy is correlated with mental energy, and is transmutable to it, has now to some extent been shown, and will be shown yet more conclusively. 9. One of the causes of indigestion is the diver- sion of the digestive energy from the processes of digestion, and the appropriation of that energy for working purposes. Many dyspeptics owe their indigestion alone to this cause. And for my purpose of classification, I distinguish them as the energy-diversion dyspeptics. The class consists almost wholly of lean people, and is made up mainly from those adult brain workers whose occupation involves difficult mental effort, in which there is little or nothing of the habitual, automatic or routine quality. This class includes persons who, in addition to an otherwise sufficient day's work for mind and body, are, simultane- ously with such work, busy with mental effort also, and prolong the extra mental effort into the hours of leisure, rest and recreation. Exception- ally bright but delicate school children are dys- peptics of this energy-diversion class. 104 ENERGY-DIVERSION DYSPEPSIA. 10. To make the idea of this volitional energy a little more vivid and distinct, I need only point to the well-known relation between the maximum number of working hours that make up a day's work in the various occupations, ranging from the purely unskilled physical to the purely volitional mental. The occupations of men might be ranged into a half-dozen grades, according to the amount of volitional mental en- ergy involved. And we would have no such energy in the case of the purely unskilled physi- cal laborer who, for example, is shoveling sand; and would have only such energy in the case of the purely mental worker who, for example, is busy with the marshaling of hosts of facts for the purpose of proving a doctrine. Once trained to the work, a man can easily shovel sand ten hours a day, six days in the week. A great variety of clerical work is sufficient to exhaust the power of the worker at six to seven hours per day for five and a half days in the week. And for such work as Charles Darwin did always, and Thomas Carlyle did much of the time, four hours per day proved quite enough, and three hours were all that Darwin could do a great deal of his time. The higher the form in which we employ our surplus working energy, the shorter is its daily duration. 11. When a man is tired he should ease up, ARGUMENT. 105 slow down, or come to a full stop in his work. He knows this without being told. He knows that his inclinations and feelings guide him per- fectly during health. But there are allurements to do more work. The inclinations, often disre- garded, may cease to be felt, may cease to serve as a hint to stop work for a time, or for the day. Darwin often acknowledged doing overwork, and more than once expressed himself as having no warning sensation of the fact. The special fea- ture of mental overwork that concerns us in this essay, is that it involves the diversion and appro- priation for work, or attempts at work, of the energy that belongs to the apparatus of diges- tion. 12. The overworked and overtired man is not well qualified to make the most and best of his next installment of food. His digestive appara- tus is without sufficient force for operation. His dinner is not made to yield all its force. And the next sitting at work will be proportionately less fruitful of results. The maximum quantity and quality of work are not obtainable without perfect digestion. The worst fault, however, and the special error of the energy-diversion dyspeptic, consists in commencing work before his food has had time to yield any of its energy for the pur- pose like trying to get work out of an engine 'before steam is got up. By this error the dys- io6 ENERGY-DIVERSION DYSPEPSIA. peptic simply diverts the digestive energy for purposes of work, or for purposes of what often prove to be unsuccessful attempts at work, but no less disastrous for that reason. An unsuc- cessful attempt costs no less energy than if it were successful. Digestion falls as far short of completion as the period of rest after eating is incomplete. There will be some digestion, more or less, and some work is possible, also more or less, generally less. There will also be some in- digestion, some rotting of the food. And there will be more or less illness, the nature of which has been described, explained and accounted for in the preceding essay. 13. The several nondescript ills that are so often spoken of as distinct diseases, and which have been styled mal-nutrition, anaemia, hysteria, nervous debility, nervous exhaustion and nervous prostration, are results of indigestion, no matter what the cause of indigestion itself may be. These dependent ills, however, are more common among the energy-diversion dyspeptics, because the dyspeptic of this class is a more persistent and chronic sufferer. He is poor in energy be- cause his occupation requires its constant paying out, and also presents constant temptation to pay out more than he has to spare. I have said enough of these dependent ills in my first essay (articles 44 to 47 inclusive) to serve the purposes ARGUMENT. loy of this essay as well. In my first essay (article 41) I made brief mention of functional disease of the heart as often present and dependent on indi- gestion. The energy-diversion dyspeptic often suffers from functional disturbances of the circu- lation, and the patient is then generally alleged to have heart disease. The alleged heart disease subsides as promptly as the indigestion is cured and some strength is recovered. This alleged heart disease is more prevalent, in a mild way, among the diversion class, but is, I believe, more acute, abrupt and violent among the monotonous diet dyspeptics. When the patient has heart disease independently of his dyspepsia, the func- tional disturbance will be augmented by the in- digestion, and may be augmented to a degree that may prove fatal. I have known this to oc- cur, and I suspect it occurs oftener than we are aware of. The individual who has heart disease can least of all men afford to be a dyspeptic. 14. There is no good reason why hearts should be structurally any more perfect than eyes. About one person in five employs the aid of glasses for purposes of vision, and many more than one in five are in need of such aid. A heart will not necessarily wear out the sooner because it is defective in structure, any more than an eye which imperfectly serves the purposes of vision. There are then a great many hearts 108 ENERGY-DIVERSION DYSPEPSIA. which are more or less imperfect in respect of structure; and the owners of them are generally unaware of the fact. That a heart is structurally defective does not mean that it serves its ordi- nary purposes any the less well. There is a wide range of effort that is required of hearts. Many a heart, doing its ordinary every-day work perfectly well, will be found, by virtue of struc- tural defect, to serve its owner inadequately in his attempts at fast running, fast going up stairs mountain climbing, heavy lifting or pulling. In these extraordinary bodily efforts of the person, the heart must also make extraordinary effort. The circulating blood must move with greater rapidity and with greater force. And it is under such circumstances that the defective heart is observed to be unable to move the blood along with sufficient speed and force. The owners of such hearts can not safely indulge in extra- ordinary and prolonged muscular efforts; but with appropriate care and restraint, intuitive or prescribed, there is no good evidence to show that they do not live just about as long as those who have structurally perfect hearts. 15. The heart is a compound pump, and con- sists principally of muscular tissue; it is a com- plicated muscle. The power of this pump that keeps the circulating blood in motion, or the power of the muscle that constitutes the heart, ARGUMENT. ICQ is not inherent in the muscle itself, but has the same origin as the power of any other muscle of the body, the same origin as any other force of the animal. It is derived from the digested foods. The power of the heart is as variable as that of any other muscle, and its available force varies under the same circumstances that other muscles vary in force. A heart that is mechan- ically defective in structure may be unable to propel the circulating blood with all the force and speed which the heart muscle has the power of exerting. It may therefore happen that a heart which appears powerful, will fail to do its share in particular of an extraordinary physical effort of the person in general. Physically, a man may be said to be as strong as his heart. The heart, being mechanically inefficient for extraordinary service, is said to be diseased, although this may only mean that the heart is structurally defective, and is no more serious than to say that the eye is diseased because it can not focus rays of light, or can not adjust itself to near vision, or to far vision. 1 6. We easily understand that a man must become physically weak when underfed, also when his food profits him nothing because not digested. We are also to bear in mind that the heart shares in this weakness. An ill-fed per- son means an ill-fed heart The brain worker IIO ENERGY-DIVERSION DYSPEPSIA. who is muscularly weak, and who habitually uses up his mental energies to the utmost unit, and habitually continues his work beyond the point of fatigue, will, as we have shown, draw upon the energies that are reserved for mainte- nance, for digestion, for circulation, and so on. We have seen that some such mental workers become dyspeptics; their digestion failing be- cause the energy for that purpose is diverted to mental uses. Just the same explanation ac- counts for the functional inefficiency of the heart that is defective in structure. The overtime brain worker, especially the one who has not the capacity for the quality or quantity of the work- he undertakes, draws upon the energies of main- tenance in general, and the result shows itself in incomplete digestion and an inefficient circu- lation. And when the circulation is observed to be faulty, and the heart is examined, the struc- tural defect may be deduced from the circum- stances and conditions of the heart's sounds. Irregularity of the working of the structurally defective heart, when it is observed in connec- tion with dyspepsia, in a person with much reduced energy, may be taken to depend wholly upon indigestion or the cause of indigestion. It is very common to take notice of, and treat the patient for, disease of the heart, and entirely dis- regard the indigestion of the case. I think it ARGUMENT. Ill must be impossible to show that such treatment ever results in any good to the patient. 17. Nervous prostration, an alarming expres- sion, represents an unimportant condition in which the energy-diversion dyspeptic often finds himself. A condition of being powerless to succeed with mental work. It is due to indi- gestion and the resulting failure of the supply of energy. Let there be absolute rest from voli- tional effort of body and mind thirty to sixty minutes after eating, and there is an end to nervous prostration. 1 8. The energy-diversion dyspeptic is so generally a sufferer from insomnia, that insomnia seems to depend upon the same cause as indi- gestion. Incidentally I should speak of insomnia under circumstances that are entirely outside of the sphere of this essay; and of these outside details first. Tea or coffee with the evening meal keeps many persons awake a large share of the night. A half or small cup of strong coffee will generally not interfere with sleep; at any rate one can reduce the amount of his evening coffee or tea so as to lose no sleep on their account. And it is often better to reduce than to abstain. I have known the tea of the noon meal to affect the person till past midnight and deprive him of a large share of his sleep. Although the cause of insomnia is sometimes 112 ENERGY-DIVKRSION DYSPEPSIA. very simple, and very near at hand, the patient may suffer many months before it is found out. 19. The sense of hunger serves as a cause of insomnia in sensitive people. Many persons are afraid to eat at night just before retiring, and, if they have even a slight sense of hunger, will sleep the less for it. There are, on the other hand, perhaps a greater number of persons who eat shortly before retiring, and the man of mental occupation will sleep the better for doing so. One should eat only a little at night, just enough to dispense with the sense of hunger; more than that may result in ill effects. A com- plex meal at night will do better than a simple one. Bread alone would not do as well as bread and butter, or a sandwich, or apiece of pie, even mince pie. The insomnia which is incidental to suffering from indigestion at night needs no explanation beyond what may be said of the cause of such indigestion. Any insomnia that may be due to mental overwork, or work con- tinued beyond the point of fatigue, need not be considered here, for the cause of it is identical with the cause of the indigestion in the same case. 20. The most important insomnia that we have to do with is a direct result of doing mental work at night. We find a great deal of this in- somnia among energy-diversion dyspeptics. It ARGUMENT. 1 13 is true that night work under certain circum- stances is the cause. How this insomnia is re- lated to dyspepsia I cannot say. It is at least associated with, if not dependent upon, indiges- tion. It seems that the particular condition of night work which makes it a cause of insomnia is that it shall be overwork, the work of one who during the day has already done to the extent of his capacity. In the testimony of two famous sufferers and habitual overworkers we will ob- serve that insomnia was always associated with mental occupation, and sometimes very hard work, during the evening and often far into the night. 21. In the first essay, I have already expressed my belief in a mental inhibition faculty, to which we owe our ability of stopping or diverting our minds from that automatic and useless activity which keeps us awake when we wish to sleep. That one is sometimes for hours an unwilling and sleepy witness to his own senseless thinking, and is unable to stop it, seems to me to be due to the tired and therefore inefficient working condition of the mind in general, and of the in- hibition, restraining, or governing faculty in par- ticular. All due to mental overwork. Suffering from insomnia, a man seems to be in the position of witness to his own delirium. The volitional thinking, that constitutes the work of the day 8 1 1 4 ENERGY-DIVERSION DYSPEPSIA. or evening, having been continued past the point of fatigue, some of the faculties continue action automatically for hours after the person has stopped volitional effort and wishes to rest and tries to do so. 22. The mental activity that keeps one awake is automatic in character. It does not indicate that there is an abundance of mental energy available, but rather, that the energy has been so far used up that none, or not enough, remains available for controlling and restraining the facul- ties. The inhibition faculty is incapacitated by fatigue, and will not serve its ordinary purpose until some rest is had and some energy recov- ered. The energy for inhibition, for restraining the faculties from this automatic thinking, is soon supplied by the little food taken by those who eat shortly before retiring. And this seems to account for bedtime eating as a suc- cessful means of preventing insomnia. Expe- rience with insomnia will teach one to antici- pate a waking spell, to recognize the- likelihood of lying awake hours by the time he has lain awake minutes. If, then, there is no special contra-inclination, one should take a little food. This procedure is very successful in cases of in- somnia with absence of dyspepsia. It is also well to notice that, at times when one is kept awake by automatic mental activity, ARGUMENT. 115 if the conditions be at all favorable, sleep can generally be induced by briefly continued efforts at volitional thinking. Volitional effort, of course, stops the automatic; and it generally happens that one falls asleep by the time the volitional efforts have continued a half minute, more or less. This element of volitional mental effort is common to, and the essential part of, the schemes that we now and then read of in journals, for in- ducing sleep in cases of insomnia. It is easy to see that there is volitional effort in the determin- ation to count, abstractly, or the strokes of a clock; to imagine seeing one's own breath, and so on. And as good a scheme as any of the class, if not the best, is to try to keep awake, keeping one's eyes open. When properly situ- ated for sleeping, it becomes very difficult to keep purposely awake. The worst insomniac finds it hard to keep intentionally awake for the purpose of listening to some one reading or speaking. 23. I have now stated what I have found to be the cause of indigestion in a class of persons whom I have designated by the descriptive title of energy-diversion dyspeptics. And I have also explained the occurrence of several ills which I hold to depend either upon indigestion, or, with it, upon the same cause. What I am writing about the causes of indigestion is based upon a Il6 ENERGY-DIVERSION DYSPEPSIA. great deal of personal experience and extensive observation extending back more than twenty years. It is not practicable to refer to the details of suffering, and the circumstances and conditions under which they occur, in the lives of private individuals yet living. But such liberty can for purposes of proof be taken, by the consent of all concerned, with the lives of great men now gone, whose record has been published, and concern- ing whom any additional particulars or interpre- tations are eagerly welcomed, whether they simply cast new light on the great characters themselves, or illuminate the uncertain path of the admiring follower. One man can learn from another man's experience, and there can be no reasonable doubt that the energy-diversion dys- peptics of to-day can learn much, and perhaps enough for their purpose, from the forty years' suffering of Charles Darwin, and the fifty-five years' experience of Thomas Carlyle as dyspep- tics of this class. Dyspepsia and its dependent ills are as mysterious to the more recent suffer- ers as they were to Darwin and Carlyle. And that, I may repeat, is my apology for writing this book. EVIDENCE FROM CHARLES DARWIN. I. In "The Life and Letters of Charles Dar- win." edited by his son, Francis Darwin, we shall EVIDENCE FROM CHARLES DARWIN llj find an interesting, instructive and authentic record of his illness and suffering, extending through a period of fifty years of his life. The biographer writes of Darwin, "that for nearly forty years he never knew one day of the health of ordinary men, and that thus his life was one long struggle against the weariness and strain of sickness." Not much stress is laid by the biographer on the occasional illness of Darwin during the ten or more years preceding the last forty of his life. For our purpose, however, it will be important to notice all allusions to his earlier ills, and ob- serve the circumstances and conditions under which he suffered. 2. In studying Charles Darwin as a dyspeptic, it seemed to me that every mention of, or allu- sion to, his illness, or any of the circumstances or conditions under which he suffered, had some important meaning, either alone or together with other items of the record. I believe, therefore, it will serve my purpose best to use every item of the biography which will throw any light on any aspect of his illness, at any time of his life except- ing the extremes of youth and age. And I believe it will be best to present the facts of Darwin's ills in the order in which they appear in the biography, which varies but little from the order in which they occurred. n8 ENERGY-DIVERSION DYSPEPSIA. There will be many repetitions, but under varying circumstances. And the fact of many repetitions will the better show the continued persistence of Darwin's errors and the penalties that were always associated with them. 3. The biography of Charles Darwin, by his son, Francis Darwin, from which I gather the particulars of his illness, consists of two volumes. For every extract made therefrom, I will refer to the page from which I take it. What state- ments are quoted literally will be indicated by quotation marks. Statements which I take from the biography, but express in my own words, which I will rarely do, will be indicated alone by page references. All the data I have, two or three items ex- cepted, relative to Charles Darwin's health, are here, once for all, acknowledged to be due to the two volumes by his son, Francis Darwin. It will be observed that, with four exceptions, the extracts as far as page 171 are from the first volume of the biography, and those beyond page 17 1 are from the second volume. It will there- fore not be necessary to specify the volume from which an extract is taken. 4. The following collection of extracts, relative to the illness of Charles Darwin, will be ac- companied by as little comment and explanation as possible. It should therefore be stated here, EVIDENCE FROM CH ARISES DARWIN. 119 at the outset, that the extracts are intended to show that Mr. Darwin for more than forty years habitually committed those errors which serve as the causes of the indigestion of the energy- diversion class of dyspeptics. 5. The reader will observe that Mr. Darwin, in addition to having been a great sufferer from indigestion, also suffered from all the dependent ills. He had evidently a structurally defective heart, and several times during his life, and obviously near the close of it, the functional disturbance of his circulation was very conspicuous. A good item of evidence of the defect of Darwin's heart, was the fact, as stated by himself, that the sum- mer of 1842, when he was about thirty-three years of age, was the last time in his life that he "was ever strong enough to climb mountains or to take long walks such as are necessary for geological work" (59). It will appear that Darwin suffered a great deal from insomnia, and was also often, when thoroughly disabled, in the condition called nervous prostration. 6. The reader should particularly notice: I. That Darwin's work was of the purely volitional mental kind, requiring his highest grade of energy, and exhausting it in less time than any other kind of work would do. 120 ENERGY-DIVERSION DYSPEPSIA. II. That he worked with all his might, gen- erally up to, and often beyond, the point of fatigue. III. That what he considered his day's work was done between eight and half past nine o'clock, and between half past ten and twelve, or a quarter past all in the forenoon; three to three and a quarter hours, the one part just after breakfast, the other part shortly before the noon meal (90- IV.

That at the water-cure establishments, to which he frequently resorted, but only when forced by illness to stop work, he generally re- covered his health his digestion sleep and energies. The regulations of the establishment prevented him from working, and the enforced rest was the secret of his prompt recovery and recuperation; the procedures of the water-cure being merely incidental, and useful as passive exercise and diversion, and as a means upon which to hinge the patient's faith and the pro- prietor's bill. XL That he did not always recover at the water-cure; when it will also be noticed that he employed his mind during his stay, with revi- sions, correspondence, etc., or at least with read- ing; thus eliminating the element of rest from his sojourn at the establishment. XII. That Darwin's health was alternately better and worse. With work he became ill; with rest he became better, and again set to work in always the same erroneous way, to become ill again, to be again forced to take another period of rest, and so on, for more than forty years. And if his recoveries were often incom- plete it was because his rests were incomplete. 7. In May, 1873, Darwin, replying to some questions by Mr. Galton, wrote relative to his health: "Good when young, bad for last thirty- three years." 122 NRGY-DI VERSION DYSPEPSIA. Relative to "energy of body, etc.," he wrote: "Energy shown by much activity, and whilst I had health, power of resisting fatigue. I and one other man were alone able to fetch water for a large party of officers and sailors utterly pros- trated. Some of my expeditions in South America were adventurous. An early riser in the morning" (II, 356). This shows that Darwin dated the period of his bad health from 1840, when he was about thirty-one years of age. There is no conclusive evidence that Darwin's ill health was to any ex- tent due to any hereditary influence. To sortie extent his father, Dr. R. W. Darwin, suffered from gout (II, 356); and that he (the father) had at least some time suffered from indigestion seems to be indicated by the statement that he could never eat cheese (I, 14), and that he was in the habit of drinking hot water in the evening after his dinner (I, 16). 8. On December 27, 1831, Darwin sailed with the Beagle on her famous voyage of circumnavi- gation. The voyage lasted four years and nine months. Concerning the time spent at Plymouth awaiting the departure of the ship, he wrote: "These two months at Plymouth were the most miserable which I ever spent, though I exerted myself in various ways. I was out of spirits at the thought of leaving all my family and friends FROM CHARLES DARWIN. 123 for so long a time, and the weather seemed to me inexpressibly gloomy. I was also troubled with palpitation and pain about the heart, and like many a young ignorant man, especially one with a smattering of medical knowledge, was convinced that I had heart disease. I did not consult any doctor, as I fully expected to hear the verdict that I was not fit for the voyage, and I was resolved to go at all hazards" (53, 54). 9. Of the time between his return to England (October 2, 1836) and his marriage (Jan 29, 1839), Darwin wrote: "These two years and three months were the most active ones which I ever spent, though I was occasionally unwell, and so lost some time" (56). "During these two years I took several short excursions as a relaxation, and one longer one to the Parallel Roads of Glen Roy" (57). It already appears thus early in his career (before 1839), that he is working at science with all his might to the fullest endurable extent of his time. He is already overworked and already suffering for it. On the excursion for relaxation to Glen Roy he gathers data for a paper ex- plaining the Parallel Roads. That is to say, instead of an excursion for relaxation, this proved to be a working expedition. "As I was not able to work all day at science, I read a good deal during these two years on 124 ENERGY-DIVERSION DYSPEPSIA. various subjects" (57), suggesting that, if he could have done so, he would have worked all day at science. 10. Of the time between his marriage and settling at Down, he wrote: "During the three years and eight months whilst we resided in London, I did less scientific work, though I worked as hard as I possibly could, than during any other equal length of time in my life. This was owing to frequently recurring unwellness, and to one long and serious illness." "The greater part of my time, when I could do any- thing, was devoted to my work on 'Coral Reefs.' . . . This book, though a small one, cost me twenty months of hard work, as I had to read every work on the Islands of the Pacific, and to consult many charts" (58). ' 'Nor did I ever intermit collecting facts bearing on the origin of species; and I could sometimes do this when I could do nothing else from illness" (58). 11. "In the summer of 1842 I was stronger than I had been for some time, and I took a little tour by myself in North Wales, for the sake of observing the effects of the old glaciers which formerly filled all the larger valleys. . . . This excursion interested me greatly, and it was the last time I was ever strong enough to climb moun- tains or to take long walks such as are necessary for geological work" (59). 12. * 'During the early part of our life in London, I was strong enough to go into general society, and saw a good deal of several scientific men" (59). ' 'Whilst living in London, I attended as regularly as I could the meetings of several scientific societies, and acted as secretary to the Geological Society. But such EVIDENCE FROM CHARLES DARWIN. 125 attendance, and ordinary society, suited my health so badly that we resolved to live in the country, which we both preferred and have never repented of" (64). 13. He settled at Down, September 14, 1842. "Few persons can have lived a more retired life than we have done. Besides short visits to the houses of re- lations, and occasionally to the seaside or elsewhere, we have gone nowhere." "During the first part of our residence we went a little into society, and received a few friends here; but my health almost always suffered from the excitement, violent shivering and vomiting attacks being thus brought on." ''I have therefore been compelled for many years to give up all dinner parties, and this has been somewhat of a deprivation to me, as such parties always put me into high spirits. From the same cause I have been able to invite here very few scientific acquaintances" (64, 65). 14. "My chief enjoyment and sole employment throughout life has been scientific work; and the excite- ment from such work makes me, for the time, forget, or drives quite away, my daily discomfort." (65). ' 'I record in a little diary which I have always kept, that my three geological books ('Coral Reefs' included) consumed four and a half years steady work; and now it is ten years since my return to England. How much time have I lost by illness?" (65). Referring to his work on 'Cirripedia', he wrote: "Although I was employed during eight years on this work; yet I record in my diary that about two years out of this time was lost by illness." 15. "On this account I went in 1848 for some months to Malvern for hydropathic treatment, which did me much good, so that on my return home I was able to resume work." 126 ENKRGY-DIVKRSION DYSPEPSIA. "So much was I out of health that when my dear father died on November 13, 1848, I was unable to attend his funeral, or to act as one of his executors" (66). 16. "In September, 1858, I set to work by the strong advice of Lyell and Hooker to prepare a volume on the transmutation of species, but was often interrupted by ill health, and short visits to Dr. Lane's delightful hydro- pathic establishment at Moor Park" (70). 17. "On January ist, 1860, 1 began arranging my notes for my work on the 'Variation of Animals and Plants under Domestication' ; but it was not published until the beginning of 1868; the delay having been caused partly by frequent illnesses, one of which lasted seven months, and partly by being tempted to publish on other subjects which at the time interested me more" (73). 18. "In the autumn of 1864 I finished a long paper on 'Climbing Plants' and sent it to the Linnean Society. The writing of this paper cost me four months; but I was so unwell when I received the proof sheets that I was forced to leave them very badly and often obscurely ex- pressed. The paper was little noticed, but when in 1875 it was corrected and published as a separate book it sold well" (75). 19. ' 'The 'Descent of Man' took me three years to write, but then as usual some of this time was lost by ill health, and some was consumed by preparing new editions and other minor works" (76). 20. Writing in May, 1881, of having lost to a great extent his aesthetic tastes, and that even as a schoolboy he took intense delight in Shakes- peare, etc., he says: " I have tried lately to read Shakespeare, and found it so intolerably dull that it nauseated me" (81). 21. "My habits are methodical, and this has been of EVIDENCE FROM CHARGES DARWIN. 127 not a little use for my particular line of work. Lastly, I have had ample leisure from not having to earn my own bread. Even ill health, though it has annihilated several years of my life, has saved me from the distractions of society and amusement" (85). The preceding extracts are from the one auto- biographical chapter of the work quoted. 22. ''Indoors he sometimes used an oak stick like a little alpenstock, and this was a sign that he felt giddi- ness" (88). "He had his chair in the study and in the drawing- room raised so as to be much higher than ordinary chairs; this was done because sitting on a low or even an ordinary chair caused him some discomfort" (89). "He became very bald, having only a fringe of dark hair behind." 23. "His face was ruddy in color, and this perhaps made people think him less of an invalid than he was. He wrote to Dr. Hooker, June 13, 1849: 'Every one tells me that I look quite blooming and beautiful, and most think I am shamming; but you have never been one of those.' " "And it must be remembered that at this time he was miserably ill, far worse than in later years" (89, 90). "His expression showed no signs of the continual dis- comfort he suffered. When he was excited with pleasant talk his whole manner was wonderfully bright and ani- mated, and his face shared to the full in the general ani- mation" (90). 24. "Two peculiarities of his indoor dress were that he almost always wore a shawl over his shoulders, and that he had great loose cloth boots lined with fur which he could slip pn over his indoor shoes." "Like most delicate people he suffered from heat as well as from chilliness; it was as if he could not hit the 128 ENKRGY-DIVERSION DYSPEPSIA. balance between too hot and too cold. Often a mental cause would make him too hot, so that he would take off his coat if anything went wrong in the course of his work" (90). 25. "He rose early, chiefly because he could not lie in bed, and I think he would have liked to get up earlier than he did. He took a short turn [walk] before breakfast, a habit which began when he went for the first time to a water-cure establishment. This habit he kept up till almost the end of his life" (91). 26. "After breakfasting alone about 7 : 45, he went to work at once, considering the one and one-half hours be- tween 8 and 9 : 30 one of his best working times." "At 9 : 30 he came into the drawing-room for his letters, rejoicing if the post was a light one and being sometimes much worried if it was not. He would then hear any family letters read aloud as he lay on the sofa." "The reading aloud, which also included part of a novel, lasted till about 10 : 30, when he went back to work till 12 or 12:15. By this time he considered his day's work over, and would often say, in a satisfied voice, Tve done a good day's work.' He then went out-of-doors whether it was wet or fine" (91). 27. "My father's midday walk generally began by a call at the greenhouse, where he looked at any germi- nating seeds or experimental plants which required a cas- ual examination, but he hardly ever did any serious ob- serving at this time. Then he went on for his constitu- tional" (93). "In earlier times he took a certain number of turns [rounds on a certain walk] every day, and used to count them." "Of late years I think he did not keep to any fixed number of turns, but took as many as he felt strength for" (93). His walks were "either round the sand walk, EVIDENCE FROM CHARLES DARWIN, 1 29 or outside his own grounds in the immediate neighborhood of his own house. The sand walk was a narrow strip of land, one and one-half acres in extent, with a gravel walk round it" (93). It was round this gravel walk that he took the turns mentioned. 28. "The sand walk was our playground as children, and here we continually saw my father as he walked round. It is curious to think how, with regard to the sand walk in connection with my father, my earliest reco- lections coincide with my latest; it shows how unvary- ing his habits have been" (93). Darwin was an example of "regular living." His life was very much without the important element of change. 29. ' 'Sometimes when alone he stood still or walked stealthily to observe birds or beasts. It was on one of these occasions that some young squirrels ran up his back and legs, while their mother barked at them in an agony from the tree. He always found birds' nests even up to the last years of his life, and we, as children, considered that he had a special genius in that direction. In his quiet prowls he came across the less common birds." " He used to tell us how, when he was creeping noise- lessly along in the 'Big Woods,' he came upon a fox asleep in the daytime, which was so much astonished that it took a good stare at him before it ran off." "And I remember his collecting grasses, when he took a fancy to make out the names of all the common kinds" (94). All which shows that he did not on these outings take complete mental rest. It is men- 9 130 ENERGY-DIVERSION DYSPEPSIA. tally somewhat trying, I should say, to make such efforts as are here mentioned, and to succeed. 30. "Within my memory, his only outdoor recreation be- sides walking, was riding, which he took to on the recom- mendation of Dr. Bence Jones, and we had the luck to find for him the easiest and quietest cob in the world, named 'Tommy.' He enjoyed these rides extremely, and devised a number of short rounds which brought him home in time for lunch" (95). 1 1 1 think he used to feel surprised at himself, when he remembered how bold a rider he had been, and how utterly old age and bad health had taken away his nerve. He would say that riding prevented him thinking much more effectually than walking that having to attend to the horse gave him occupation sufficient to prevent any real hard thinking. And the change of scene which it gave him was good for spirits and health. Unluckily, Tommy one day fell heavily with him on Keston Common. This, and an accident with another horse, upset his nerves, and he was advised to give up riding" (96). 31. " Luncheon at Down came after his midday walk; and here I may say a word or two about his meals gen- erally. He had a boy-like love of sweets, unluckily for himself, since he was constantly forbidden to take them. He was not particularly successful in keeping the 'vows', as he called them, which he made against eating sweets, and never considered them binding unless he made them aloud" (96). " He drank very little wine, but enjoyed, and was revived by, the little he did drink. He had a horror of drinking, and constantly warned his boys that anyone might be led into drinking too much." 32. "After his lunch he read the newspaper, lying on the sofa in the drawing-room. I think the paper was the EVIDENCE FROM CHARLES DARWIN. 131 only non-scientific matter which he read to himself (97). Everything else novels, travels, history was read aloud to him. He took so wide an interest in life that there was much to occupy him in the newspapers, though he laughed at the wordiness of the debates; reading them, I think, only in abstract. His interest in politics was considerable, but his opinion on these matters was formed rather by the way than with any serious amount of thought." 33. "After he had read his paper, came his time for writing letters. These, as well as the manuscript of his books, were written by him as he sat in a huge horse- hair chair by the fire, his paper supported on a broad board resting on the arms of the chair. When he had many or long letters to write, he would dictate them from a rough copy" (97). 34. "He received many letters from foolish, unscrupu- lous people, and all of these received replies. He used to say that if he did not answer them, he had it on his conscience afterwards, and no doubt it was in great measure the courtesy with which he answered every one which produced the universal and wide-spread sense of his kindness of nature, which was so evident on his death." "He was considerate to his correspondents in other and lesser things, for instance, when dictating a letter to a foreigner, he hardly ever failed to say to me, 'You'd better try and write well, as it's to a foreigner.' " "His anxiety to save came in a great measure from his fears that his children would not have health enough to earn their own livings, a foreboding which fairly haunted him for many years" (99). 35. "When letters were finished, about three in the afternoon, he rested in his bedroom, lying on the sofa and smoking a cigarette, and listening to a novel or other book not scientific." 132 ENERGY-DIVERSION DYSPEPSIA. " He only smoked when resting, whereas snuff was a stimulant, and was taken during working hours. He took snuff for many years of his life, having learnt the habit at Edinburgh as a student" (99). "The reading aloud often sent him to sleep, and he used to regret losing parts of a novel, for my mother went steadily on lest the cessation of the sound might wake him" (100). " He came down at four o'clock to dress for his walk, and he was so regular that one might be quite certain it was within a few minutes of four when his descending steps were heard." "From about half past four to half past five he worked; then he came to the drawing-room, and was idle till it was time (about six) to go up for another rest with novel reading and a cigarette" (100). 36. "Latterly he gave up late dinner, and had a simple tea at half past seven (while we had dinner), with an egg or a small piece of meat." "After dinner he never stayed in the room, and used to apologize by saying he was an old woman, who must be allowed to leave with the ladies. This was one of the many signs and results of his constant weakness and ill health. Half an hour more or less conversation would make to him the difference of a sleepless night, and of the loss perhaps of half the next day's work" (100). 37. "After dinner he played backgammon with my mother, two games being played every night; for many years a score of the games which each won was kept, and in this score he took the greatest interest. He became ex- tremely animated over these games, bitterly lamenting his bad luck and exploding with exaggerated mock anger at my mother's good fortune." "After backgammon he read some scientific book to himself, either in the drawing-room, or, if much talking was going on, in the study." EVIDENCE FROM CHARGES DARWIN. 133 "In the evening, that is, after he had read as much as his strength would allow, and before the reading aloud began, he would often lie on the sofa and listen to my mother playing the piano" (101). 38. The scientific reading in the evening "as much as his strength would allow" was quite enough to account for the night's insomnia. And the three other mental occupations of the even- ing, backgammon, hearing music, and hearing the reading of part of a novel, were also favor- able to the insomnia of a man who had been doing head work nearly all day. "He became much tired in the evenings, especially of late years, when he left the drawing-room about ten, going to bed at half past ten." 39. "His nights were generally bad, and he often lay awake or sat up in bed for hours, suffering much discom- fort. He was troubled at night by the activity of his thoughts, and would become exhausted by his mind working at some problem which he would willingly have dismissed." "At night, too, anything which had vexed or troubled him in the day would haunt him, and I think it was then that he suffered if he had not answered some troublesome person's letter" (102). 40. "The regular readings, which I have mentioned, continued for so many years, enabled him to get through a great deal of the lighter kinds of literature. He was extremely fond of novels, and I remember well the way in which he would anticipate the pleasure of having a novel read to him, as he lay down, or lighted his cigar- ette." 41. "Much of his scientific reading was in German, 134 ENERGY-DIVERSION DYSPEPSIA. and this was a great labor to him; in reading a book after him, I was often struck at seeing, from the pencil marks made each day where he left off, how little he could read at a time." "He used to call German the 'Verdammte.' He was especially indignant with Germans, because he was con- vinced that 'they could write simply if they chose, and often praised Dr. F. Hildebrand for writing German which was as clear as French" (103). He had much trouble to learn German, and to read it; pronounced it as if English, and, in learning, neglected the grammar, sought out only the meaning. It was drudgery to read it, and therefore at great cost of mental energy (104). 42. "It was a sure sign that he was not well when he was idle at any times other than his regular resting hours; for, as long as he remained moderately well, there was no break in the regularity of his life." "Week-days and Sundays passed by alike, each with their stated intervals of work and rest. It is almost im- possible, except for those who watched his daily life, to realize how essential to his well-being was the regular routine that I have sketched, and with what pain and difficulty anything beyond it was attempted." 43. "Any public appearance, even of the most modest kind, was an effort to him. In 1875 he went to the little village church for the wedding of his elder daughter, and he could hardly bear the fatigue of being present through the short service. The same may be said of the few other occasions on which he was present at similar cere- monies" (105). "When, after an interval of many years, he again attended a meeting of the Linnean Society, it was felt to be and was in fact a serious undertaking; one not to be FROM CHARLES DARWIN. 135 determined on without much sinking of heart, and hardly to be carried into effect without paying a penalty of sub- sequent suffering." "In the same way a breakfast party at Sir James Paget's, with some of the distinguished visitors to the Medical Congress (1881), was to him a severe exertion" (106). 44. "The early morning was the only time at which he could make any effort of the kind, with comparative impunity. Thus it came about that the visits he paid to his scientific friends in London were by preference made as early as ten in the morning. For the same reason he started on his journeys by the earliest possible train, and used to arrive at the houses of relatives in London when they were beginning their day" (106). 45. "He kept an accurate journal of the days on which he worked and those on which his ill health prevented him from working, so that it would be possible to tell how many were idle days in a given year. He also entered the day on which he started on a holiday and that of his return." "The most frequent holidays were visits of a week to London, either to his brother's or to his daughter's. He was generally persuaded by my mother to take these short holidays when it became clear, from the frequency of 'bad days, ' or from the swimming of his head, that he was being overworked. He went unwillingly, and tried to drive hard bargains, stipulating, for instance, that he should come home in five days instead of six." 46. "Even if he were leaving home for no more than a week, the packing had to be begun early on the previ- ous day, and the chief part of it he would do himself" (106). "The discomfort of a journey, to him was, at least latterly, chiefly in the anticipation, and in the miserable sinking feeling from which he suffered immediately be- 136 ENERGY-DIVERSION DYSPEPSIA. fore the start; even a fairly long journey, such as that to Coniston, tired him wonderfully little, considering how much an invalid he was; and he certainly enjoyed it in an almost boyish way, -and to a curious extent." 47. "Every walk at Coniston was a fresh delight, and he was never tired of praising the beauty of the broken, hilly country at the head of the lake" (107). Every walk at Coniston was a "fresh delight" in contrast to the walks for exercise and recrea- tion and rest about his own grounds so near home; walks that were taken as so much duty to be done, and for which he may have regretted the time and strength, and which he had often, too often and monotonously, repeated. These walks at Coniston do not seem to have tired him, because he did not enter already tired upon them, and because they were a fresh delight change, total change, of circumstances. ( 'One of the happy memories of this time (1879) is that of a delightful visit to Grassmere. 'The perfect day,' my sister writes, 'and my father's vivid enjoyment and flow of spirits, form a picture in my mind that I like to think of. He could hardly sit still in 1he carriage for turning round and getting up to admire the view from each fresh point' " (107). "Besides these longer holidays, there were shorter vis- its to various relatives." "He always particularly enjoyed rambling over rough, open country." 48. "He never was quite idle even on these holidays, and found things to observe. At Hartfield he watched Dro- sera catching insects, etc. ; at Torquay he observed the EVIDENCE FROM CHARLES DARWIN. 137 fertilization of an orchid (Spiranthes), and also made out the relations of the sexes in thyme" (107). 49. "My father had the power of giving to these sum- mer holidays a charm which was strongly felt by all his family. The pressure of his work at home kept him at the utmost stretch of his powers of endurance, and when released from it, he entered on a holiday with a youthful- ness of enjoyment that made his companionship delight- ful. We felt that we saw more of him in a week's holi- day than in a month at home." 50. "Some of these absences from home, however, had a depressing effect on him; when he had been previously much overworked it seemed as though the absence of the customary strain allowed him to fall into a peculiar con- dition of miserable health" (108). 51. "Besides the holidays which I have mentioned, there were his visits to water-cure establishments." "In 1849, when very ill, suffering from constant sick- ness, he was urged by a friend to try the water-cure, and at last agreed to go to Dr. Gully's establishment at Mal- vern. His letters to Mr. Fox show how much good the treatment did him; he seems to have thought that he had found a cure for his troubles; but, like all other remedies, it had only a transient effect on him. However, he found it, at first, so good for him that when he came home he built himself a douche-bath, and the butler learnt to be his bathman" (108). "He paid many visits to Moor Park, Dr. Lane's water- cure establishment in Surrey. These visits were pleas- ant ones, and he always looked back to them with pleasure." 52. "Dr. Lane said of him: 'He never preached nor prosed, but his talk, whether grave or gay (and it was each by turns) , was full of life, and salt, racy, bright, ani- mated' " (109). "He always put his whole mind into answering any of his children's questions" (114). 13$ ENERGY-DIVERSION DYSPEPSIA. "As a host my father had a peculiar charm; the pres- ence of visitors excited him, and made him appear to his best advantage" (115). "He used to say of himself that he was not quick enough to hold argument with anyone, and I think this was true. Unless it was a subject on which he was just then at work, he could not get the train of argument into working order quickly enough" (117). 53. "I must say something of his manner of working. One characteristic of it was his respect for time; he never forgot how precious it was. This was shown, for in- stance, in the way in which he tried to curtail his holi- days; also, and more clearly, with respect to shorter periods. He would often say that saving the minutes was the way to get work done. He showed this love of sav- ing the minutes in the difference he felt between a quar- ter of an hour and ten minutes' work; he never wasted a few spare minutes from thinking that it was not worth while to set to work." "I was often struck by his way of working up to the very limit of his strength, so that he suddenly stopped in dictating with the words, 'I believe I mustn't do any more,' The same eager desire not to lose time was seen in his quick movements when at work." 54. "He could not endure having to repeat an experi- ment which ought, if complete care had been taken, to have succeeded the first time, and this gave him a contin- ual anxiety that the experiment should not be wasted. He felt the experiment to be sacred, however slight a one it was." "He wished to learn as much as possible from an ex- periment, so that he did not confine himself to observing the single point to which the experiment was directed, and his power of seeing a number of other things was wonderful" (122). "In the literary part of his work he had the same hor- EVIDENCE FROM CHARTS DARWIN. 139 ror of losing time, and the same zeal in what he was do- ing at the moment; and this made him careful not to be obliged unnecessarily to read anything a second time" (122). "He allowed no exception to pass unnoticed" (125). 55. "He enjoyed experimenting much more than the work which only entailed reasoning, and when he was engaged on one of his books which required argument and the marshaling of facts, he felt experimental work to be a rest or holiday. Thus, while working upon the 'Variations of Animals and Plants,' in 1860-61, he made out the fertilization of orchids, and thought himself idle for giving so much time to them." ' 'It is interesting to think that so important a piece of research should have been undertaken and largely worked out as a pastime, in place of more serious work." "The letters to Hooker of this period contain expres- sions such as, 'God forgive me for being so idle; I am quite silily interested in this work' (126,127). He speaks in one of his letters of his intention of working at Drosera as a rest from the 'Descent of Man' " (127). 56. Darwin worked seven days a week, and at each sitting worked to the utmost limit of his strength, and then sought rest in change of men- tal work which was good so far as it broke monotony and engaged his mind on something fresh, but it was not rest from work. And this way of doing explains Darwin's great physical weakness, his indigestion. The processes of physical maintenance became insufficient be- cause his energy was too extensively, too contin- uously, and too exclusively appropriated for men- tal work of the most exhausting kind. 140 KNKRGY-DIVERSION DYSPKPSIA. Much of Darwin's work was all the more exhaustive of energy because it was not easy for him. The work of revising and correcting proofs he found especially wearisome (130). "He did not write with ease. . . . He corrected a great deal, and was eager to express himself as well as he possibly could. . . . On the whole, I think the pains which my father took over the literary part of his work was very remarkable" (131). 57. Darwin's ideas may have cost him little work. Formulating, preserving and expressing them seem to have been more difficult, and we have seen that literary composition was hard work for him. But I am unwilling to believe that such work was naturally difficult for Darwin. I would rather say that any work in particular must be difficult when one's energies are de- voted to too much work in general. With an hour of absolute rest after each of three meals a day, and no mental work at all during the evening, the great Darwin, I fully be- lieve, would have had perfect digestion and perfect sleep, and would have had, I am sure much more mental energy to work with, and his work would all have been easy to him, and absolutely pleasant. And while the quantity of his life work was large and the quality un- questionable, what might it not have been had EVIDENCE FROM CHARLES DARWIN. 141 he understood and attended to the sources of his working power, the proper conditions of its generation and limitations of its uses! 58. "If the character of my father's working life is to be understood, the conditions of ill health, under which he worked, must be constantly borne in mind He bore his illness with such uncomplaining patience that even his children hardly, I believe, realize the extent of his habitual suffering. ... No one indeed, except my mother, knows the full amount of suffering he endured, or the full amount of his wonderful patience. For all the later years of his life she never left him for a night; and her days were so planned that all his resting hours might be shared with her. She shielded him from every avoidable annoyance, and omitted nothing that might save him trouble, or prevent him from becoming over- tired, or that might alleviate the many discomforts of his ill health" (135). "But it is, I repeat, a principal feature of his life, that for nearly forty years he never knew one day of the health of ordinary men, and that thus his life was one long struggle against the weariness and strain of sickness. And this can not be told without speaking of the one condition which enabled him to bear the strain and fight out the struggle to the end" (136). 59. The preceding extracts relative to Charles Darwin are taken from the one chapter of his autobiography, and from the one chapter of "Reminiscences of His Every-day Life." Of the extracts which follow, many are from the writings of the biographer, but most of them are from the letters of Charles Darwin, and will be accompanied by the dates of the letters from 142 ENERGY-DIVERSION DYSPEPSIA. which they are taken. These dates will show the range of time through which Darwin's ills extended. The extracts from the letters may to some extent repeat the facts embodied in the autobi- ography and reminiscences. But I think there will be nothing of tiresome monotony in the manner in which the few repetitions occur. I consider the letters to be the best source of the evidence we want. The allusions to Darwin's illness were written at or near the times of his suffering, and are therefore better than any record made from memory. It will often happen, also, that the circum- stances and conditions under which the letters were written, clearly point to errors that were quite sufficient to accountfor the illnesses alluded to. For example, on page iv of his preface, the biographer says: "My father's letters give frequent evidence of having been written when he was tired or hurried, and they bear the marks of this circumstance." 60. 1829, July 4. Aged 20 years. "I started from this place about a fortnight ago to take an entomological trip with Mr. Hope through all North Wales; and Bar- mouth was our first destination. The first two days I went on pretty well, taking several good insects, but for the rest of that week my lips became suddenly so bad, and I myself not very well, that I was unable to leave the room, and on the Monday I retreated with grief and sorrow back again to Shrewsbury" (154).

Writing of a college examination which he had just passed, he says: "Before I went in, and when my nerves were in a shattered and weak condition, " (155). 63. i8jO) November 5. "I have so little time at pres- ent, and am so disgusted by reading, that I have not the heart to write to anybody. ... I have not spirits or time to do anything- Reading makes me quite desperate; the plague of getting up all my subjects is next thing to intolerable" (157). 64. 1831, November 75. Writing of the excellence of the Beagle and her fittings shortly before sailing, he says: "In short, everything is well, and I have only now to pray for the sickness to moderate its fierceness, and I shall do very well" (188). 65. iSji, December j. Aged 22. Writing of the prospective start of the Beagle, he says: "I look for- ward even to seasickness with something like satisfac- tion, anything must be better than this state of anxiety" (189). 66. 1832, July. "At sea when the weather is calm, I work at marine animals with which the whole ocean abounds. If there is any sea up I am either sick or contrive to read some voyage or travels" (194). The biographer says: 67. "It has been assumed that his ill health in later years was due to his having suffered so much from seasickness. This he did not himself believe, but rather accredited his bad health to the hereditary fault which 144 ENERGY-DIVERSION DYSPEPSIA. came out as gout in some of the past generations. I am not quite clear as to how much he actually suffered from seasickness; my impression is distinct that, according to his own memory, he was not actually ill after the first three weeks, but constantly uncomfortable when the vessel pitched at all heavily. But, judging from his letters, and from the evidence of some of the officers, it would seem that in later years he forgot the extent of the discomfort from which he suffered" (197). 68. 1836, June 3. From the Cape of Good Hope. "It is a lucky thing for me that the voyage is drawing to a close, for I positively suffer more from seasickness now than three years ago" (197). 69. "Admiral Lord Stokes wrote to the Times, April 25, 1883: "Perhaps no one can better testify to his early and most trying labors than myself. We worked to- gether for several years at the same table in the poop cabin of the Beagle during her celebrated voyage, he with his microscope and myself at the charts. It was often a very lively end of the little craft, and distressingly so to my old friend, who suffered greatly from seasick- ness. After perhaps an hour's work he would say to me, 'Old fellow, I must take the horizontal for it,' that being the best relief position from ship motion; a stretch out on one side of the table for some time would enable him to resume his labors for a while, when he had again to lie down. It was distressing to witness this early sacri- fice of Mr. Darwin's health, who ever afterwards felt the ill effects of the Beagle's voyage" (198). 70. From Mr. A. B. Usborne, a shipmate. ' 'He was a dreadful sufferer from seasickness, and at times, when I have been officer of the watch, and reduced the sails, making the ship more easy, and thus relieving him, I have been pronounced by him to be 'a good officer,' and he would resume his microscopic observa- tions in the poop cabin" (198). EVIDENCE FROM CHARLES DARWIN, 145 71. "The amount of work that he got through on the Beagle shows that he was habitually in full vigor; he had, however, one severe illness in South America, when he was received into the house of an Englishman, Mr. Corfield, who tended him with careful kindness. I have heard him say that in this illness every secretion of the body was affected, and that when he described the symptoms to his father, Dr. Darwin could make no guess as to the nature of the disease. My father was some- times inclined to think that the breaking up of his health was to some exte'nt due to this attack" (198). Darwin was very glad that he went on this voyage of the Beagle (199). 72. 1832, February 8. "In the Bay of Biscay there was a long and continuous swell, and the misery I endured from seasickness is far beyond what I ever guessed at. . . . Nobody who has only been at sea for twenty- four hours has a right to say that seasickness is even uncomfortable. The real misery only begins when you are so exhausted that a little exertion makes a feel- ing of faintness come on. I found nothing but lying in my hammock did me any good" (200). 73. On the tenth day of the voyage, in the harbor of Santa Cruz, Darwin first felt even moderately well. " I find I am very well, and stand the little heat we have had as yet as well as anybody" (203). 1832, March /, Bahia. "I find the climate as yet agrees admirably with me" (204). 1832, May.

I find my life on board, when we are on blue water, most delightful, so very comfortable and quiet it is almost impossible to be idle, and that for me is say- ing a good deal" (209). 75. 1832, June. "I am sure you will be glad to hear how very well every part (Heaven forefend, except sea- sickness) of the expedition has answered. ... I can eat salt beef and musty biscuits for dinner. See what a fall man may come to!" (213). 76. 1832, August 18.

"What miserable work, again, it is searching for prior- ity of names. I have just finished two species, which possess seven generic, and twenty-four specific names. My chief comfort is, that the work must be sometime done, and I may as well do it as anyone else" (347). 121. 1852, March 7. Aged forty-three. "Very many thanks for your most kind and large invitation to Dela- mere, but I fear we can hardly compass it. I dread going anywhere, on account of my stomach so easily failing under any excitement. I rarely even now go to London; not that I am at all worse, perhaps rather bet- ter, and lead a very comfortable life with my three hours of daily work, but it is the life of a hermit." ' { My nights are always bad, and that stops my becom- ing vigorous. You ask about water-cure. I take at intervals of two or three months, five or six weeks of moderately severe treatment, and always with good effect. ... I am now at work on the sessile Cirri- pedes, and am wonderfully tired of my job; a man to be a systematic naturalist, ought to work at least eight hours per day. . . . How paramount the future is to the present when one is surrounded by children. My dread is hereditary ill health. Even death is better for them" (349). 122. 1852, October 24. "I do indeed regret that we live so far off from each other, and that I am so little locomotive. I have been unusually well of late (no EVIDENCE; FROM CHARGES DARWIN. 163 water-cure), but do not find that I can stand any change better than formerly. . . . The other day I went to London and back, and the fatigue, though so trifling, brought on my bad form of vomiting. ...

I hope by next summer to have done with my tedious work. ... I agree most entirely, what a blessed discovery is cloroform. . . . The other day I had five grinders (two by the elevator) out at a sitting under this wonderful substance, and felt hardly any- thing" (352). 123. 1854, March i. Aged forty-five. One thousand, two hundred words. Reading of the country described in Hooker's "Himalayan Journal," Darwin said, "One can feel that one has seen it (and desperately uncomfort- able I felt in going over some of the bridges and steep slopes)." "I think my stomach has much deadened my former pure enthusiasm for science and knowledge" (360). 124. From J. Hooker 1 s notes. Concerning Hooker's meetings with Darwin: "This began with an invitation to breakfast with him at his brother's house in Park Street, which was shortly afterwards followed by an in- vitation to Down to meet a few brother naturalists. In the short intervals of good health that followed the long illness which oftentimes rendered life a burden to him, between 1844 and 1847, I had many such invitations, and delightful they were" (387). "A more hospitable and more attractive home under every point of view could not be imagined of society there were most often Dr. Falconer, Edward Forbes, Professor Bell, and Mr. Waterhouse there were long walks, romps with the children on hands and knees; music that haunts me still. Darwin's own hearty man- 164 ENERGY-DIVERSION DYSPEPSIA. ner, hollow laugh, and thorough enjoyment of home life with friends; strolls with him altogether, and interviews with us one by one in his study, to discuss questions in any branch of biological or physical knowledge that we had followed; and which I at any rate always left with the feeling that I had imparted nothing and carried away more than I could stagger under." "Latterly, as his health became more seriously affected, I was for days and weeks the only visitor, bringing my work with me and enjoying his society as opportu- nity offered. It was an established rule that he every day pumped me, as he called it, for half an hour or so in his study, when he first brought out a heap of slips with questions botanical, geographical, etc., for me to answer, and concluded by telling me of the progress he had made in his own work, asking my opinion on various points." "I saw no more of him till about noon, when I heard his mellow ringing voice calling my name under my window this was to join him in his daily forenoon walk around the sand-walk. . . . A stout staff in his hand; away we trudged through the garden, where there was always some experiment to visit, and on to the sand- walk, around which a fixed number of turns were taken, during which our conversation naturally ran on foreign lands and seas, old friends, old books, and things far off to both mind and eye." "In the afternoon there was another such walk, after which he again retired till dinner if well enough to join the family; if not, he generally managed to appear in the drawing-room. . . . He enjoyed the music or con- versation of his family" (388). 125. 1844, July. "I must leave this letter till to-morrow, for I am tired; but I so enjoy writing to you, that I must inflict a little more on you" (391). 126. 1845, October 12. "I have found that even trifling observations require, in my case, some leisure and energy, EVIDENCE FROM CHARLES DARWIN. 165 both of which ingredients I have had none to spare, as writing my Geology thoroughly expends both. . . .

From May, 1856, to June, 1858, Mr. Darwin "remained for the most part at home, but paid several visits to Dr. Lane's Water-Cure Establishment at Moor Park, during one of which he made a pilgrimage to the shrine of Gil- bert White atSelbourne" (426). 128. 1856) May 3.

"I was very sorry to run away so soon and miss any part of my most pleasant evening; and I ran away like a Goth and Vandal without wishing Mrs. Hooker good-bye; but I was only just in time; as I got on the platform the train had arrived.

"People all say 'how much better you look!' The grand improvement I trace is that of being far calmer than I was. "...

At work again, November 15, on an article on Sir Walter Scott. "He began it with indifference. The 'steam got up', and he fell into what he called the old sham happy, nervously excited mood too well known to him." 74. f8j8, February 15. "We are generally alone in the evenings, tranquil over our books and papers. What visitors and visiting we have are in the middle of the day. With my will I would go out nowhere in the evening. It never fails to do me more or less harm" (107). Of a party he attended: "The whole thing went off very well, and I returned about one in the morning with a headache that served me for more than a day after. 'It will help your lectures,' Jane said. Maybe so; but in the meantime it has quite hindered my natural sleep and composure" (108). 1838, February. "All Saturday sick and nervous" (in). f8j8, March 8. "Went to a soiree of Miss Martineau's. . . . I go as rarely as I can to such things, for they EVIDENCE FROM THOMAS CARI^E. 221 always do me ill. A book at home is suitabler, with a quiet pipe twice in the evening, innocent spoonful of porridge at ten, and bed at eleven" (114). 75. 1838, April 12. "There is a shivering precipitancy in me which makes emotion of any kind a thing to be shunned. It is my nerves, my nerves. The poor chaos is bad enough, but with nerves one might stand it." 1838, May 75. On the day of lecturing on Voltaire he was "stupid and sick beyond expression; also I did not like the man, a fatal circumstance of itself. . . . On the Shakespeare day I entered all palpitating, fluttering with sleeplessness and drug taking, with visitors, and the fatal et cetera of things" (117). Here, as in many other places, it appears that Carlyle was a man so weak mentally as to be without power to guide himself, to determine on any course of action, to make or keep any resolves; always talking of quitting literature and London, and never doing either; always a crea- ture of circumstance, afloat, adrift; never settled, always undecided (118). 76. He suffered for lecturing. "The lecture course was perhaps too prolonged. Twelve orations such as Carlyle was delivering were beyond the strength of any man who meant every word that he uttered" (119). 1838, June. "Fame brought its accompaniments of invitations to dinner which could not all be refused; the dinners brought indigestions; and' the dog-days brought heat, and heat and indigestion together made sleep im- possible. His letters to his brother are full of lamenta- tion" (120). 1838, July 27. "After lectures came a series of dinner- work and racketings; came hot weather, coronation up- 222 ENERGY-DI VERSION DYSPEPSIA. roars, and at length sleeplessness, collapse, inertia. . . . I like that existence very ill; my nerves are not made for it" (121). 77. "I corrected a few proof-sheets. I read a few books, dull as Lethe. I have done nothing else what- ever that I could help, except live. . . . My diges- tion is very bad; I should say, however, that my heart and life is on the whole sounder than it was last year" (122). 1839, February. "Seldom had Carlyle seemed in bet- ter spirits than now. . . . He had occasional fits of dyspepsia, which, indeed, seemed to affect him most when he had least that was real to complain of. ... But the dyspepsia was the main evil dyspepsia and London society, which interested him more than he would allow, and was the cause of the disorder" (133). 78. 1839, March. After his first dinner with the Bar- ings: "It was one of the most elevated affairs I had ever seen. . . . The lady of the house, one Lady Harriet Baring, I had to sit and talk with specially for a long, long while one of the cleverest creatures I have met with. . . . The dinner was after eight, and ruined me for a week. . . . She kept me talking an hour or more upstairs" (134). 79. 1839, April 16. Aged 44. "As to the praise, etc., I think it will not hurt me much; I can see too well what the meaning of that is. I have too faithful a dyspepsia working continually in monition of me, were there noth- ing else" (136). 1839, August 13, a Scotsbrig, on a two months' vaca- tion. "I am no man whom it is desirable to be too close to an unhappy mortal at least, with nerves that preap- point me to continual pain and loneliness, let me have what crowds of society I like" (143). 80. 1839, October 8, "I go out to ride daily. . . . My horse is in the best order, and does seem to do me EVIDENCE FROM THOMAS CARLYLE. 223 good. I will try it out, and see what good comes of it, dear though it be" (146). October 23. "My riding keeps me solitary. It is all executed at calling hours. . . . Green lanes, swift riding, and solitude how much more delightful. For two hours every day I have almost an immunity from pain. . . . My health is not greatly, yet it is percep- tibly, improved. I have distinctly less pain in all hours. Much solitude is good for me here" (146). 81. 1840, February 27. Anticipates the matter of lec- turing again; and the consequent "dinners, routs, callers, confusions inevitable, to a certain length. . . . I wish I was far from it. No health lies for me in that for body or for soul. Welfare, at least the absence of ill fare and semi-delirium, is possible forme in solitude only" (151). "Carlyle complained when alone, and complained when driven into the world; dinner parties cost him his sleep, damaged his digestion, damaged his temper. Yet when he went into society no one enjoyed it more or created more enjoyment. The record of adventures of this kind alternates with groans over the consequent suf- ferings" (152). 1840, March 77. "There, at the dear cost of a shattered set of nerves and head set whirling for the next eight- and-forty hours, I did see lords and lions" (152). 82. 1840, March jo. "I pass my days under the abom- inable pressure of physical misery a man foiled. I mean to ride diligently for three complete months, try faithfully whether in that way my insufferable burden and imprisonment can not be alleviated into at least the old degree of endurability. . . . For positively my life is black and hateful to me" (153). 1840^ April 23. "I am sick and very miserable. I have kept riding for the last two months. My health seems hardly to improve. I have been throwing my lectures upon paper lectures on Heroes. . . . If I were a little healthier ah me! all were well" (154)- 224 BNgRGY-DIVBRSION DYSPEPSIA. 83. 1840, May 6. Having successfully delivered two lectures this season, he wrote: "So far it is well enough. And now, alas! as the price of a good lecture my nerves are thrown into such a flurry that I got little sleep last night, and am all out of sorts to-day. Two weeks more and the sore business is done, and perhaps I shall never try it again" (156). 184.0, May 20. The fifth lecture ("The Hero as Man of Letters"), one of his best, was also one of his easiest, considered before, during and after delivery. Because it related to matters more familiar and at home and was therefore easier work, and for that reason less exhaustive of energy and less depressing in after effect (156). 84. 1840, May 23. Done lecturing for the season. " I will not be in haste to throw myself into such a tumble again. It stirs me all up into ferment, fret and confusion, such as I hate altogether. ... I will keep my horse a while longer, dear as it is, and try a little further whether there is not some good use in it worth twenty- five shillings a week yea or no" (157). 85. 1840, June 15. "My soul longs extremely to live in the country again, and yet there, too, I should not be well. I shall never be other than ill, wearied, sick- hearted, heavy-laden, till once we get to the final resb I think. . . . Dinners I avoid as the very devil. . . . They ask you to go among champagne, bright glitter, semi-poisonous excitements which you do not like even for the moment, and you are sick for a week after" (160). 86. 1840, July 15.

The fact is that just now I am very weary, and the more sleep I get I seem to grow wearier" (12). 1849, September 25. "For two nights past I have got into the bad habit of dividing my sleep in two; waking a couple of hours by way of interlude, and then sleeping till ten o'clock a bad habit, if I could mend it; but who can ?

If I could but get my meaning explained at all, I should care little in what style it was. But my state of health and heart is highly unfavorable. Nay, worst of all, a kind of stony indifference is spreading over me. I am getting weary of suffering, feel as if I could sit down in it and say, Well, then, I shall soon die at any rate. Truly all human things, fames, promotions, pleasures, prosperities, seem to me inexpressibly contemptible at times" (24). in. 1850. "Many an evening, about this time," writes the biographer, alluding to the " Latter-day Pamphlets," " I heard him flinging off the matter intended for the rest of the series which had been left unwritten, pouring out, for hours together, a torrent of sulphurous denunciation.

But, in general, his listeners sat silent." "The imagery, his wild play of humor, the immense knowledge always evident in the grotesque forms which it assumed, were in themselves so dazzling and so enter- taining, that we lost the use of our own faculties till it was over. He did not like making these displays, and avoided them when he could; but he was easily provoked, and when excited could not restrain himself" (35). 112. "The dinner with Sir Robert Peel was in the sec- ond week in May. The ostensible object was to bring about a meeting between Carlyle and Prescott" (35). 1850, August; at Savage Landor' s, in Bath. "Dinner was elaborately simple. The brave Landor forced me to talk far too much, and we did very near a bottle of claret, besides two glasses of sherry; far too much liquor and excitement for a poor fellow like me. " He does not record any suffering for and after this dinner and talk with Landor (42). After a three weeks' vacation and a trip to Scotsbrig he wrote: "I am a very unthankful, ill-conditioned, bil- lious, wayward, and heartworn son of Adam, I do sus- pect" (45). 113. i8$o y September 6, Scotsbrig. "Nothing so like a Sabbath has been vouchsafed to me for many heavy months as these last two days at poor Scotsbrig are. Let me be thankful for them. They were very necessary to me. They will open my heart to sad and affectionate thoughts, which the intolerable burden of my own mean sufferings has stifled for a long time. I do nothing here, and pretend to do nothing but sit silent, etc." (47). At Scotsbrig, at the age of 55 years, Carlyle " filled his letters with anecdotes of misfortunes, miseries, tragedies, among his Annandale neighbors, mocking at the idea that this world was made for happiness " (48). 234 ENERGY-DIVERSION DYSPEPSIA. "The kindness of these friends [he said], their very kindness, works me misery of which they have no idea. In the gloom of my own imagination, I seem to myself a pitiable man. Last night I had, in spite of noises and confusions many, a tolerable sleep, most welcome to me, for on the Monday night here I did not sleep at all. . . . No minute can I be left alone, . . . but every minute I must talk, talk. God help me!" And much more of very gloomy sort (48). ' ' It was in this humor that Carlyle read ' Alton Locke;' ... . and it speaks volumes for the merit of that book, that at such a time Carlyle could take pleasure in it" (49). 114. 1850, October, visiting. "At the Marshalls' he was prevented from sleeping by ' poultry, children, and flunkeys.' " 1850. During this summer's vacation of three months spent in various ways and places, he was everywhere dyspeptic, sleepless, irritable, and in low spirits ; and returns in October to London in the condition of a man who needs to enter upon a period of rest, instead of one who has just concluded a long vacation. At the end of this vacation he spends " ten days amid miscella- neous company in the common dyspeptic, utterly isolated, and contemptible condition " (53). 115. " Unable to produce anything, he began to read voraciously. . . . ' I fly out of the way of everybody, and would much rather smoke a pipe of wholesome to- bacco than talk to any one in London just now ' " (54).

"Having leisure on his hands, and being otherwise in the right mood, he re-read Sterling's letters, collected information from surviving relations, and without difficulty indeed, with entire ease and ra- pidity he produced in three months what is perhaps the most beautiful biography in the English language.

Returned home by express train and Calais packet in one day" 236 ENERGY-DIVERSION DYSPEPSIA. 118. At the age of 56 years Carlyle resolved to write a book on Frederick of Prussia. An immense undertaking, but he resolved to try. " For Carlyle to write a book on Frederick would involve the reading of a mountain of books, memoirs, journals, letters, state papers. . . . He would have to travel over a large part of Germany, to see Berlin and Potsdam, to examine battle-fields and the plans of campaigns. He would have to make a spe- cial study, entirely new to him, of military science and the art of war " (73). 119. 1853, December 8. "I executed a deal of riding yesterday, and after near four hours' foot and horse ex- ercise, was at South Place little after time. ' Mutton- chop with Ford ? ' There was a grand dinner. ...

Infinitely glad to get home again to a slighter measure of dyspepsia, inertia, and other heaviness, in- eptitude, and gloom. . . . Keep reading Frederick. . . . I make slow progress, and am very sensible how lame I now am in such things " (76). "Six months now followed of steady reading and ex- cerpting. He went out little, excepting to ride in the afternoons, or walk at midnight when the day's work was over. A few friends were admitted occasionally to tea." During these six months of reading, he is more or less ill and irritable (77). 121. iSjZj July 12.

"I am terribly bilious, though it might be hard to say why; everything is so delightfully kind and appropriate here. . . . Hitherto I have always got a fair day's work done. . . . Go out and smoke at intervals, as at home, etc. In fact, I am almost too well cared for and attended to. The only evil is that they will keep me in talk. Alas! how much happier I should be not talking or talked to! I require an effort to get my victuals eaten for talk " (80). " It was his own fault," says the biographer, " his talk was so intensely interesting, so intensely entertaining. No one who heard him flowing on, could have guessed at the sadness which weighed upon him when alone. . . . After a fortnight with the Erskines, he escaped to Scotsbrig," where he stayed till August 30, all the time more or less dyspeptic and sleeping poorly (81). 122. 1852, August jo. Starts to Germany.

Mrs. Carlyle wrote: "Mr. C. seems to be getting very successfully through his travels, thanks to the patience and helpfulness of Neuberg. He makes in every letter frightful misereres over his sleeping accomodations; but he can not conceal that he is really pretty well, and gets sleep enough to go on with, more or less pleasantly" (98). 1852, September 25. Carlyle writes late, till after midnight (98). About his health on the German tour of forty days: "It was a journey done as in some shirt of Nessus; misery and dyspeptic degradation, inflammation, and insomnia tracking every step of me" (102). 124. 1852, November 9.

Silent weak rage, re- morse even, which is not common with me; and, on the whole, a solitude of soul coupled with helplessness, which are frightful to look upon, difficult to deal with in my present situation." "For my health is miserable too; diseased liver I pri- vately percieve has much to do with the phenomenon; and I can not yet learn to sleep again. During all my travels I have wanted from a third to half of my usual sleep. . . . I am growing to percieve that I have be- come an old man" (104). 125.

He remembers that thirty-six or thirty-seven years ago at Craigen- puttock, on summer mornings after breakfast 3 Mrs. Carlyle used very often to come up to the 256 ENERGY-DIVERSION DYSPEPSIA. little dressing-room where he was shaving, and seat herself on a chair behind him, for the privi- lege of a little further talk while this went on. " Instantly on finishing, I took to my work, and, probably we did not meet much again till din- ner." This means talk with breakfast, talk with shaving, and work, in immediate succession, on the summer mornings referred to (305). 172. For some years it was the custom of the Carlyles, that after dinner, evenings, he would lie on the sofa, she would play the piano. He felt like sleeping, and was inclined to sleep then, but sleep was not good for him directly after dinner. This shows that sleep was practicable (308). 173. 1868. Aged 73. "Occasionally at longish intervals he allowed himself to be tempted into London society. . . . He went one evening to the Dean of Westmin- ster's." Of which he recorded: " Dinner, ^evening gen- erally, was miserable, futile, and cost me silent insomnia the whole night through. Deserved it, did I ? It was not of my choosing not quite " (311). 174. j&68, February 6. "Nothing yet done, as usual. Nothing. Oh, me miserum! Day, and days past, unus- ually fine.

" I was never so idle in my life before." "On getting back to London he worked in earnest sorting and annotating his wife's letters" (322). Occa- sional rides "formed his chief afternoon occupation; but age was telling on his seat and hand, and Comet and Carlyle's riding were both near their end." Early in October, 1868, Comet falls with Carlyle; and with this accident, from which he narrowly escaped un- injured, his riding ceased. " The marvel was that he was able to continue riding to so advanced an age, and had not met long before with a more serious accident. He rode loosely always His mind was always abstracted. He had been fortunate in his different horses. They had been ' very clever creatures.' This was his only explana- tion " (323). 176. 1869. " In the spring he was troubled by want of sleep again; the restlessness being no doubt aggravated by the ' Letters,' and by the recollections which they called up." "The 'Letters,' . . . and his own occupation with them, were the absorbing interest." 1869, April 29. " Perhaps this mournful, but pious, and ever interesting task, escorted by such miseries, night after night, and month after month perhaps all this may be wholesome punishment, purification, and monition, and again a blessing in disguise.

And Carlyle was never abk to revise further or to write an introduction to them (326) 178. j86p, October 6. Aged 74. "For a week past I am sleeping better, which is a special mercy of heaven. I dare not yet believe that sleep is regularly coming back to me; but only tremulously hope so now and then. If it does, I might still write something.

"Three nights ago, stepping out at midnight, with my final pipe, and looking up into the stars, which were clear and numerous, it struck me with EVIDENCE FROM THOMAS CARI/VT^E. 259 a strange new kind of feeling. Hah! in a little while I shall have seen you also for the last time." And busies himself at that time of night with profound think- ing just before going to bed (327). 179. Early in 1870 Carlyle became gradually incapable of using his right hand for writing. "And no misfortune more serious could have befallen him, for 'it came,' he said, 'as a sentence not to do any more work while thou livest' a very hard one, for he had felt a return of his energy" (332) His energy after this was used less for work and more for digestion, and to this alleged mis- fortune was due his better health during the last ten years of his life. He refers to his stay in Scotland this year, 1870, as "evidently doing me day by day some little good; though I have sad fighting with the quasi-infernal ingredient the railway whistle, namely and have my difficulties and dodgings to obtain enough sleep" (339). 180. 1870, November 12.

His last legible journal entry: "For many months past, except for idle reading, I am pitifully idle." This he regrets. Ideas, thoughts, still occur, which he would like to write, but is unable. Dictation does not suc- ceed, "because a person stands between him and his thoughts" (362). 182. 1875, January 30. "I have not been worse since you last heard; in fact, usually rather better; and at times there come glimpses or bright reminiscences of what I might, in the language of flattery, call health very singu- lar to me now, wearing out my eightieth year" (370). "His time was chiefly passed in reading and in dicta- ting letters. He was still ready with his advice to all who asked for it, and with help when help was needed. He walked in the mornings on the Chelsea Embank- ment. ... In the afternoon he walked in the park with me or some other friend; ending generally in an omnibus, for his strength was visibly failing" (272). 183. In Carlyle's eighty-first year he still pro- duces letters replying to young men, etc., about choice of professions one letter, for example, of four hundred and fifty words (373). "Thus calmly and usefully Carlyle's later years went by. There was nothing more to disturb him. His health (though he would seldom allow it) was good. He complained of little, scarcely of want of sleep, and suffered less in all ways than when his temperament was more impetuously sensitive" (374). 1876, May 5. "After much urgency and with a dead- lift effort, I have this day got issued through the Times EVIDENCE FROM THOMAS CARLYLE. 261 a small indispensable deliverance on the Turk and Dizzy question" (380). 184. "When the shock of his grief had worn off and he had completed his expiatory memoir, he became more composed, and could discourse with his old fulness, and more calmly than in earlier times. A few hours alone with him furnished them the most delightful entertain- ment. We walked five or six miles a day. ... As his strength declined, we used the help of an omnibus, and extended our excursions farther. In his last years he drove daily in a fly. . . . He was impervious to weather never carried an umbrella, but, with a mackin- tosh and his broad-brimmed hat, let the rain do its worst upon him" (380). Carlyle "always craved for fresh air" and so seated himself in conveyances as to get it if pos- sible( 3 8i). 185. "The loss of the use of his right hand was more than a common misfortune. It was the loss of every- thing. The power of writing, even with the pencil, went finally seven years before his death. His mind was vig- orous and restless as ever. Reading without an object was weariness. Idleness was misery; and I never knew him so depressed as when the fatal certainty was brought home to him" (387). "His correspondence with his brother John, never in- termitted while they both lived, was concerned chiefly with the books with which he was occupying himself. He read Shakespeare again. He read Goethe again, and then went completely through the 'Decline and Fall.' " 186. "I have finished Gibbon," he wrote, "withagreat deduction from the high esteem I have had of him ever since the old Kirkcaldy days, when I first read the twelve 262 ENERGY-DIVERSION DYSPEPSIA. volumes of poor Irving's copy in twelve consecutive days" (395). "I do not feel to ail anything," he said of himself, No- vember 2, 1878, "except unspeakable and, I think, increasing weakness. . . .1 am grateful to heaven for one thing, that the state of my mind continues unal- tered and perfectly clear. . . . He continued to read the Bible. . . . The Bible and Shakespeare remained 'the best books' to him that were ever written." 187. "He was growing weaker and weaker, and the exertion of thought exhausted him" (396). 1878, December 14. Aged 83. "On coming down stairs from a dim and painful night I find your punctual letter here. . . . The night before last was unusually good with me. All the rest, especially last night, were worse than usual, and little or no sleep attainable by me. " Not of dyspepsia, nor of insomnia, Thomas Carlyle died on February 5, 1881, at the age of eight-five years. ON THE MANNER OF CONDUCTING CASES. I. Of the morbid nervous phenomena and other ills that are dependent on indigestion from any cause, enough has been said in my first essay; and, though equally applicable here, it is not necessary to repeat. It is common for the energy-diversion dys- peptic to become nearly or quite well during the latter years of his life. This fact Foster in his 'Text-book of Physiology" (1878), page 563, offers to explain as follows: "The epithelial glandular elements seem to be those whose powers are the longest preserved, and hence the ON THE MANNER OF CONDUCTING CASES. 263 man who in the prime of his manhood was a 'martyr to dyspepsia' by reason of the sensitiveness of his gastric nerves and the reflex inhibitory and other results of their irritation, in his later years, when his nerves are blunted, and when therefore his peptic cells are able to pursue their chemical work undisturbed by extrinsic nervous worries, eats and drinks with the courage and success of a boy." Foster testifies to the general fact of energy- diversion dyspepsia declining to almost or quite nothing during the later years of life. But it must be evident to the reader that his explana- tion of such decline is not to be taken more seriously than as an example which shows how very far from the truth are the prevailing expla- nations of dyspepsia; which again will account for the prevailing methods of practice being so .very far from successful in curing dyspeptics. When an energy-diversion dyspeptic retires from work on account of the* disability of old age, it is plain that he quits the errors that have all along been identified with his method of working, and of course he recovers his health as certainly as if the quitting of the errors had been due to a physician's direction. During the last nine years of his life, Carlyle was unable to write on account of. partial paral- ysis ("writer's cramp") of his right hand. His health was so much the better for this alleged misfortune. He still suffered from insomnia be- 264 ENERGY-DIVERSION DYSPEPSIA. cause he spent a large share of the night read- ing. Darwin's digestion also very much im- proved late in life, but he remained a sufferer from some life-long defect of the heart, which grew worse and finally took him off. 2. The energy-diversion dyspeptic gets well in old age when he retires from work, and there- fore from the errors associated with his work; just as he gets well at any other time of life when he quits his work and takes a real vaca- tion, and remains well as long as he remains away from his errors. How promptly the errors are followed by illness, how certainly the illness compels cessation from work, and how promptly the enforced rest restores health, are often shown in the cases of Darwin and Carlyle, and are shown with especial clearness in the extracts following: 1864, August J. "Worked too late yesterday. Walked out for exercise at seven p. M. . . . My walk was gloomy, sad as death. ... I read till mid- night, then out again, solitary as a ghost, and to bed at one. I see nobody." August 2. "I am out of sorts; no work hardly; and am about as miserable as my worst enemy could wish." August j. "I am better than yesterday, still not quite up to par." "My little ten-day tour," said Darwin, "October 8, 1845, rnade me feel wonderfully strong at the time, but the good effects did not last." Such experiences certainly prove the value of ON THE MANNER OF CONDUCTING CASES. 265 rests as every-day affairs, and the wisdom of the one day in seven as a whole day of rest. When these brain workers neglect the little daily rests, and, like Darwin and Carlyle, take theirs in wholesale lots after some months, or one or more years, they certainly suffer no light penal- ties for such erroneous ways of resting. And where in such cases there is no actual illness present, serious bodily defects become painfully obvious along towards middle life, if not very much sooner. A little, thin, shriveled, over- sensitive woman, not likely to be chosen for any part in the perpetuation of the race; but she was the most distinguished member of her class at college! Not only during old age are spontaneous recoveries likely to take place, but they are common at all times of life. And, when the circumstances are noted, such recoveries can easily be accounted for. A thin student at college, working forenoons, afternoons and late evenings, seven days in the week, no recreation nor vacation, is extremely likely to be sooner or later a dyspeptic of the energy-diversion sort, and will remain so while his manner of working remains so. But with the end of this way of working comes the end of his dyspepsia, a spon- taneous recovery. A schoolgirl of thirteen years was thin, 266 ENERGY-DIVERSION DYSPEPSIA. dyspeptic, and displayed much anxiety about her school work. She often combined study with eating, and she often hurried to school immediately after the morning 1 and noon meals. When the faults in the case became apparent, she was simply taken out of school to continue her studies, none the less, under a specially employed teacher at home. Anxiety about studies was discouraged, meals were taken in peace, and study was not resumed until an hour after meals. This girl got entirely well, and during the eighteen months immediately follow- ing this change she grew thirty pounds heavier. The utter absurdity of medicines in a case like this needs no mention. Cases like this have also been treated as though it were the study, or the confinement indoors, that was wrong. Study need not be stopped, even temporarily. It is only the circumstances that are wrong, partly at the home and partly at the school, and these can easily be righted. School children, thin ones especially, need to have their meals in peace, and should be re- strained from study, or any continued volitional mental effort, for at least thirty minutes after meals. They should rest one day in seven from continuous volitional mental effort. And if, owing to church or Sunday school attendance, or Sunday reading, this day's rest is not had on ON THE MANNER OF CONDUCTING CASES. 267 Sunday, it should be regularly had on some other day. Rest of mind is referred to. In re- gard to rest of body, let each one be left to his own inclinations. It is only extraordinary phys- ical effort that will cause diversion of the energy of digestion. It may not be at all necessary to restrain any child, not even the most intellectual; perhaps it is only less urging and less encourging that is in many cases needed. When I lately heard a public- school-teacher lauded because "her classes made as good a showing of progress as any in the county," I simply remarked that I would be afraid to send my children to that teacher. 3. When by a process of questioning it is found that diversion of energy is the cause of the dyspepsia in a case that presents itself for treatment, the proper course to pursue will con- sist in instructing the patient in such a way as to clearly point out the errors that he has been committing, and the reasons why they are errors; and how it is that these errors cause the indiges- tion of the case. This instruction, which will consist of teach- ing as distinguished from merely telling, when put to practical use by the patient, will result in his taking his meals in peace, under circumstances that will excuse him from talking and listening at meals; and he will accordingly neither talk 268 ENERGY-DIVERSION DYSPEPSIA. nor pay direct attention to the talk of others at meal times. Both talking and listening are done at the expense of energy that is required for digestion in this class of cases. The same peace and quiet of mind must be maintained for at least one hour after eating. And, in some cases where the resulting prostration is extreme, the patient should eat alone and be free from any stimulus to voluntary mental activity for at least two hours after eating. If he can eat but little at a time, and is for that reason to eat oftener than three times a day, he must not during treatment be engaged in any voluntary mental occupation whatever. The automatic thinking may be let alone, as it costs very little energy, and is at any rate not amenable to any useful control. The patient must be so placed that the main- tenance of these conditions will be practicable. He may need to be taken and kept away from his usual surroundings and associates for such a length of time aj may be necessary for his re- form, and to be convinced of the merits of such reform, and to regain some of his lost flesh. Returning home in a few weeks, resuming his work, gauging his hours and efforts to his energies, he will continue to improve physically, and continue to understand more and more of the advantages of the new way. One may easily ON THE MANNl'.R OF CONDUCTING CASES. 269 fail to cure such a case if the instruction falls short of personal direction, encouragement and restraint. A patient of this kind is of course supposed to suspend work during the conduct of his case, but that is not necessary in every instance. To remain at his regular occupation is a great dis- advantage, and has the effect of making recupera- tion much slower, but it will be none the less complete and lasting. It happens rather frequently that a patient, earnestly wishing to get well, is hindered by infavorable circumstances which he can not easily control. His position, occupation or business, may entail overtime work, circum- stances may prevent him having his meals in peace, or may prevent him having sufficient rest afterwards. A dyspeptic so situated may, how- ever, get his instructions, reform as far as he can at the time, and complete his reforms at such future time as circumstances will permit. What is said in my first essay, relative to in- structing a pcitient at his home, or taking him away for better control, applies to cases of energy- diversion dyspepsia as well as to other cases. 4. It is to be remembered that, when diversion of energy is alone the cause of indigestion, the diet of the patient is not to be concerned in the 270 ENERGY-DIVERSION DYSPEPSIA. treatment of the case. But it generally happens that one does not long suffer from energy- diversion dyspepsia before he is led by erroneous ideas, or erroneous treatment, into additional errors. Dyspepsia beginning with energy-diver- sion as the cause, the patient is erroneously led to regard the commoner items of food as, in his case, more or less indigestible. He is led to take exceptions to the intuitively correct, but thoughtless, way of living, of the thoughtless class of people; and, in respect of methods of subsistence, he departs from the ways of his ancestry and kin, and sets out to improve upon them, and comes to additional grief. The energy- diversion dyspeptic next falls into the errors of monotonous repetition of such things as seem to him, and are alleged to be, easier of digestion. A paroxysm of illness comes upon him. He is forced to stop work, and temporarily suspends eating; then, of course, rapidly improves. On the resumption of eating he tries a diet recom- mended for its easy digestibility. As he has not yet resumed work, his energies are free and available for digestion. As the trial diet is new to him, is a change, it works perfectly well, and for that reason is at once adopted for regular use. The patient continues this new diet, and does very well for a few weeks possibly. The stomach will soon be tired of the monotonous ON THE MANNER OF CONDUCTING CASES. 271 repetition, and to the illness from energy-diversion is added the illness from the too long continued monotonous repetition. It is so common for the energy-diversion dys- peptic to fall into the additional errors of monot- onous dieting, that his instruction would be in- complete and insufficient for practical purposes if it did not include the matter of my first essay. III. STALE-FOOD DYSPEPSIA. ON THE CAUSES. I. THERE is not a shovelful of soil on the sur- face of the earth but contains vital spores, germs or seeds, ready to develop their respective forms, and reproduce and multiply their kinds, under favorable conditions of moisture and heat. There is not an ounce of food but, by brief ex- posure to the air of any human habitation, will become infected with vital spores or germs, which will develop their respective forms, and vastly multiply their kinds, under favorable conditions of heat and moisture, and at the expense of the material which they infect. On the dry and less perishable foods, the microbe may simply find an abiding-place, with- out conditions favorable to its multiplication at the material's expense. On the more perishable foods exposed to air, moisture, and heat, the microbe soon lays hold, and the food is de- stroyed by changes which are familiar to us as spontaneous animal and vegetable decomposi- tions. Microbian life disorganizes animal and vege- (272) ON THK CAUSES. 273 table structures whenever and wherever condi- tions are favorable, but it also reorganizes them. Two classes of structures result. The one class is on a higher scale of organization, the other is on a lower scale than the original structure. The resulting structures of the higher scale are higher by virtue of being endowed with vitality. They constitute the microbian organisms that have been built up out of the original structure by the agency of life. The resulting structures of the lower scale of organization are called the " by-products of microbian multiplication." 2. We should observe that food materials are of two classes: Amyloids and albuminoids. Amy- loids are composed of carbon, hydrogen, and ox- ygen, and embrace starch, sugars, dextrine, nat- ural gums and fats. Albuminoids, in addition to carbon, hydrogen, and oxygen, contain also ni- trogen, and a little sulphur and phosphorus. The more perishable constituents of animal and vege- table structures are albuminoids. Another way of distinguishing the two classes of food mate- rials is to speak of the albuminoids as the nitrog- enous, and of the amyloids as the non -nitroge- nous, structures. The amyloids, or non-nitrogenous structures, " are comparatively stable, and do not spontane- ously decompose;" but albuminoids, or nitrog- enous structures, " not only decompose sponta- 18 274 STALE-FOOD DYSPEPSIA. neously themselves, but drag down the amyloids, with which they are associated, into concurrent decomposition not only change themselves, but propagate a change into amyloids." The first stage of the spontaneous decomposi- tion of any particular material, of either class mentioned, means its recomposition, mainly into a more complex structure, endowed with vitality, and secondarily into a more simple structure, which is called the by-product. If the retrograde change continues, the decomposing material is ultimately reduced to the mineral elements from which it was built up by vital agencies. These ultimate mineral elements are called the end- products of decomposition. The microbian life itself, and its by-products, are incidental or transi- tional products, occurring in the course of changes that finally terminate with the end-products. In the consideration of stale foods as causes of illness, we are chiefly concerned with the by- products of the spontaneous decomposition of the nitrogenous or albuminoid food materials. 3. The illnesses considered in this essay will be held to be due primarily to the infection of foods by microbian life, and the circumstance that under some conditions the gastric juice fails to sterilize foods thus infected; and secondarily to " the accumulation in the blood (or on the mucous surfaces, to be absorbed into the blood) ON THK CAUSES. 275 of poisonous chemical substances, by-products of microbian multiplication." " These by-products' of albuminoid fermenta- tion (for there are many kinds) have now been isolated from their microbian culture fluids, and analyzed. They may be regarded as alkaloids of albuminoid decompositions, and are called pto- mains. They are, most of them, deadly poisons. Septic poison, which is the by-product of putre- factive fermentation, that is, of the multiplication of putrefactive bacillus, is the most familiar ex- ample." " Every form of fermentation has its peculiar chemical by-product, and many of these are poi- sonous. The different kinds of alcohol, ethylic, amylic, etc., and different kinds of organic acids, such as lactic, acetic, butyric, etc., are familiar examples."* 4. As a rule, every meal that is swallowed is infected with the germs of microbian life. No harm, however, can result from that circumstance alone. But when we swallow foods in which de- composing changes have already made more or less progress, we take in large colonies of mi- crobes. And along with them we also take in the concomitant and often dangerously poisonous by-products. When such foods are sterilized just * Prof. Joseph Le Conte, in Pacific Medical Journal, September, 1889. 276 STAIvE-FOOD DYSPEPSIA. before ingestion, the microbian life will be de- stroyed by the heat, but its by-products will be- come none the less dangerous. In cities, even under the most favorable circumstances, there must always be some doubt about the condition of milk that comes from the country during warm weather. And under ordinary circum- stances there can be no doubt that the milk is in a decomposing condition when delivered to the consumer. At the time of making butter, by the small scale method mostly used, the milk or cream from which it is separated is already old and in a decomposing condition. Of the very best creamery butter, made on the large scale, the curd remaining in it constitutes at least one per cent. Let a pound of butter be put into a vessel suitable for observation, the vessel then immersed in hot water; when the butter has melted, the cloud-like masses of decomposing curd may be observed. Butter is infected food. When it has also be- come stale, and the odor of butyric acid proves that the butter is itself decomposing, it may no longer appear on the dining-room table, but it is nevertheless used in the kitchen. It is then called cooking butter. If the boarder does not put it on his bread, he will get it nevertheless in his mashed potatoes, in his gravies from the fry- ing-pan or from the roasting-pan, or in the hard ON THE; CAUSKS. 277 sauce for his pudding, or in fancy pastries. Even though cookingof the rancid butter also cooks the microbe, and renders it innocuous, we are not so positive about its effect on the poisonous butyric acid and other by-products. At any rate, I have observed persons whose digestion was perfectly good at their own homes, but while boarding at restaurants during absence of their families they suffered from indigestion under circumstances which indicated that it was with the fats used in cooking that the cause of their suffering lay. 5. Bread is generally moist; it presents a com- paratively large amount of surface to the air, es- pecially the cut surface, and if it becomes twelve hours old, more or less, during warm weather, or in a warm place during cold weather, it can, on a sufficiently minute examination, be observed to be infected with fungus. It is then stale bread. It can be disinfected by toasting. A good way is to slice it and put it in the oven awhile before using. If no harm results from eating stale bread, it is only because it goes into a vigorous stomach where there is a prompt and sufficient supply of the germicidal gastric juice for disinfection purposes. A sick person's stomach, however, is generally not to be relied on to do its own sterilizing or disinfection; hence the wisdom of toasting bread for sick folks, and the explanation of toast often 278 STALK-FOOD DYSPEPSIA. agreeing better than simple bread. The use of bread in a stale condition is in conformity with a very erroneous custom that is extensively preva- lent, and is upheld by almost all physicians. Bread should as certainly be fresh as any other item of food. The dry, hard, unleavened varieties of bread, such as are used by soldiers on cam- paign duty, and by sailors at sea, are good so long as they are kept dry; but musty biscuits, we shall have cause to suspect, when diarrhea and dysentery are in the military camp, are not less disastrous than the powder and lead of the enemy. What is true of bread applies with more force to cakes. Pies and cakes that are fresh are safe. It is in the stale condition that rich pastry is chargeable with a great deal of indigestion, and only to that condition of it belongs the doubtful reputation that attaches to pastry in general. 6. Ice cream is a safe luxury when the cream of which it is made is fresh. Aside from any reference to the microbe, I would rather have my ice cream at the commencement of my dinner than at the end of it; because it is probable that so much as a dish, of anything so cold as ice cream is, would, in the stomach, cause at least a slight functional disturbance, which can be much more safely endured by a stomach that is com- paratively empty and inactive, than by a stomach ON THE CAUSES. 279 that is loaded and busy. And, incidentally, where there is some temptation to load the stom- ach heavily, ice cream at the conclusion of dinner- is too much in the nature of "the last straw." 7. In the matter of re-serving dishes, bringing to the table a second or third time the remnant of a dish that has already been served, the fault of monotonous repetition, and the sometimes evil results thereof, have been shown in my first essay. An additional fault of such repeating, in warm weather, lies in the fact that such foods so re-served are often stale, badly infected, and too ready to undergo decomposition, with too great danger that the microbian energy may exceed the gastric energy, and the rotting processes out- do the processes of digestion. When such remnants are thoroughly heated just before being served, the microbian life which they may contain will be destroyed; but such heating does not destroy the poisons that may have already been formed. It has often hap- pened, for example, that persons have suffered from eating of a remnant of chicken potpie re- served. It will generally be found that where the prac- tice of re-serving prevails among people of seden- tary habits in cities, there is room for improve- ment of the digestion of the individuals concerned. 8. What has already been said of other things 28O STAJ^-FOOD DYSPEPSIA. applies also to fruits; more particularly in cities, and among the less vigorous people. I have known paroxysms of indigestion to be caused by cherries that were stale. I have observed decidedly unpleasant results from eating water- melon in small quantities in the city, and I am sure that one may sit down in the patch where they grow and eat watermelons to the fullest limit of his capacity, and suffer no harm what- ever. If the watermelon is ripe when it leaves the country, it undergoes some process of change for the worse before it is consumed in the city. Most of our good ripe fruits are too perishable to endure their ordinary usage and remain in good condition for a day or two in the city dur- ing warm weather, not to mention shipment to distant parts. Many persons in cities can not eat fruits with any freedom without suffering, so they allege. It remains in any particular case to observe under what circumstances such a person attempts to use fruit and what condition the fruit is in. To reduce fruit eating to the last degree of safety for those to whom it is unsafe, it should be eaten quite ripe and absolutely fresh, other- wise it shall have been just recently stewed or baked. Unfortunately for a large share of tinned fruit, and more so for the consumers of it, it does not go directly from the parent stem to the tin. ON THE CAUSES. 28l 9. Berries that are visibly moldy are ac- cepted by the canner and put up as pie fruit. Fruits that are badly spotted are received by the canner, the rotten parts cut away and the re- mainder put up as pie fruit. Let a pie contain such fruit, and be twenty-four hours old, during warm weather, and no wonder it will give a bad reputation to pies in general, in the mind of the consumer whose stomach can distinguish matters of quality in foods. Sometimes, when the weather favors the simultaneous ripening of an unusually large amount of fruit, and also favors the simultaneous spoiling of it, it comes to the city in amounts that exceed the demands of the retailer. The canner then finds his opportunity and for his own price gets large amounts of fruit that have already been too long from the parent stem, considering the weather, and may yet deteriorate much more before being finally sterilized and sealed. The same remarks apply to inferior qualities of canned vegetables. There are also inferior qualities of canned fish. Sometimes the interval between catching and canning the fish may have been too long, or the weather may have been exceptionally warm and therefore unfavorable for the keeping of the catch until sealed up. 10. And here it should be remembered that 282 STALE-FOOD DYSPEPSIA. all animal foods, fats excepted, being composed of nitrogenous or albuminoid structures to a vastly greater proportionate extent than vege- table foods, become very much more dangerous to life when ingestedin an infectedcondition. This is because it is from albuminoid structures that the most dangerously poisonous by-products of decomposition are formed. While infected vege- table foods will perhaps cause illness as often as animal foods in the same condition, the latter are likely to prove fatally poisonous. There is no small amount of canned meat that is of inferior quality, and it has sometimes been found to be dangerous, not only making those who use it ill, but occasionally killing some one. When a single individual is made ill by poison- ous food, or is killed by it, the real cause is likely to be overlooked. It will simply be announced that he died of stomach trouble, and that his illness was very brief. When, however, a number of persons are made simultaneously ill, manifesting similar phenomena, one or two of them narrowly escaping death, the truth is developed. The "stomach trouble" of the lone case is on general principles conceded to be so mysterious that no one is expected to give any further explanation as to cause of death. II. From a contribution by Prof. Wm. H. Welch to the second volume of "An American ON THK CAUSES 283 Text-book of the Theory and Practice of Medi- cine,"* page 38, I quote the following:-- "Here may be mentioned the not uncommon instance of poisoning, often of a large number of people, from the ingestion of decomposing or altered fish, mussels, oysters, sausage, canned meats, ham, milk, cheese and ice cream. These are due to intoxication, and chiefly to the class of bacterial poisons called ptomains produced in the early stages of certain kinds of decomposition. In certain cases of poisoning with milk, cheese, and ice cream Vaughan has demonstrated a toxic pcomain which he calls tyrotoxicon." The heating that is incidental to the canning of foods destroys the microbian life that infests them, but it does not destroy the poisonous by- products of any decomposition that may have been going on. Nor are these poisons rendered innocuous by a further cooking before reaching the table of the consumer. Even if it be rare that inferior qualities of canned fish and meat are dangerously poisonous, they are often at least slightly poisonous, and, being decomposed even to a very slight extent, they are the more ready to resume decomposi- tion when again exposed to the air after being opened, and the more ready to continue the rot- ting process even after reaching the stomach. Such inferior qualities of canned meat and fish are also especially dangerous during warm * By Dr. Wm. Pepper, Philadelphia, 1894. 284 STALE-FOOD DYSPEPSIA. weather, if remnants of them are served a second or third time. 12. Some species of microbian organisms do not require air for their existence and multiplica- tion. And this accounts for their action inside of a sealed tin of meat or fish which has been put up in a manner that must have been defective, especially in the detail of heating. Tins of food materials that have been defectively put up are not uncommon in the output of canneries. When the cases of tins reach the retail dealer, he recognizes the faulty tins by the convexity of their ends, which should be concave (tins of acid fruits excepted). The convexity, or bulging, of the ends of the can is due to the contained gases that are always being evolved during fermenta- tive changes. What becomes of these "swell heads," as they are called, is not easy to find out. They are a source of danger to the consumer. The retailer may sell them if he can, and he generally can. Or he may return them to the wholesaler, and even if the wholesaler returns them to the can- nery, it may, nevertheless, happen that they are bought up by unscrupulous speculators, who punch another little hole in the top of the can, press its convexity into concavity, solder up the little hole, and sell these tins of dangerous foods at a rate which alone is suspicous of something wrong. ON THE CAUSES. 285 Every can of food will be observed to have one little hole punched in the top, which has been soldered up. The faulty cans that have been treated as I have described have two such sold- ered holes. But it is practicable to disguise such faulty cans completely, as the necessity of mak- ing a second hole may be avoided by reopening the first one, by melting the solder which closes it, and, after concaving, soldering it up again. 13. It is during warm weather that we are most liable to the dangers that attend the use of stale foods. And in tropical climates these dangers present themselves whenever it is at- tempted to subsist after the manner prevailing in temperate climates. Dr. Andrew Duncan writes*: "The affections included under the term 'bowel com- plaints' demand our attention with greater importunity in tropical campaigns than those of any other class. For, however healthy in other respects a campaign may be, we shall always meet with 'bowel complaints.' . . . In fact, the experience of all army surgeons has ever been in this direction." Of fourteen campaigns of as many wars con- ducted by the British, Dr. Duncan finds "bowel complaints" to have headed the list of diseases in ten. *"The Prevention of Disease in Tropical Campaigns," by Andrew Duncan, M. D., etc., Surgeon Bengal Army. 286 STALE-FOOD DYSPEPSIA. "Desgenettes states that a greater number of men died from dysentery between 1792 and 1815 in the French army, than fell in the great battles of the empire." Since the Napoleonic era, the sanitary circum- stances of the soldier, during times of peace and war, have been very much improved; but such improvement can yet be carried to a further at- tainable extent, which furthering is, in fact, the object of Dr. Duncan's valuable book. 14. In the causation of bowel complaints among soldiers and camp followers there have been two factors monotonous subsistence, and the general unfitness of stale or infected foods. Two examples of the operation of the twofold cause appear in the following extract from Dr. Duncan, page 125: "The diet should be varied as much as possible. Men get sick of a constant monotonous diet, and moreover, digestion gets out of order, and in a condition predispos- ing to bowel complaints. The salt ration, if in excess, is one of the most, if not the most, predisposing causes for bowel complaints. Long-continued salt rations are ab- solutely certain to bring on these affections. "In the first Burmese war, 1824-6, for six and a half months the troops had salt rations shortly after its com- mencement, and forty-eight per cent perished within ten months, principally of scorbutic dysentery. "Here the cattle were in the first place marched to Cal- cutta from distant stations and slaughtered in February, 1824, under a degree of heat so great that decomposition must have set in. It was then salted. * 'Again, in the China war of 1840, notwithstanding this ON THE CAUSES. 287 terrible precedent, Government had learnt nothing. Cat- tle were again marched to Calcutta and slaughtered in the heat of February, with the same consequences to the British troops. The meat was half putrid when the force sailed. In one regiment, the Twenty-sixth Cameronians, embarking nine hundred strong and full of health, the re- sult was, that at the end of two months there were not two hundred men left fit for duty in the field, owing to the havoc made by scorbutic dysentery. (Martin, Maclean.}' ' 15. The following additional extract from Dun- can, pages 78 and 79, is for the purpose of showing that, in the conduct of wars, there are yet prevail- ing the disastrous errors of monotonous subsist- ence, and the dangerous errors of using "cheap and inferior supplies: " "I may now sum up a few of the results to be attained in campaigns in warm climates, where especially we have to guard against monotony of diet: "i. Vary the food by different tinned meats from Aus- tralia, New Zealand, and America, but beware of cheap and inferior supplies. "2. Where possible, drive live cattle with the force in preference to carrying meat supplies. "3. Discard all compressed vegetables, using, where necessary, only preserved. "4. Requisition the invaded country for supplies. ' '5. Look out for the natural products of the country. Yams were obtained in Malay, melons, potatoes, and cucumbers in Afghanistan; wild cress, cabbage, and sow thistle in New Zealand; begonia and elephant apple in Aka. Fowls can be obtained also everywhere gen- erally. "6. Never give salted and preserved rations at a 288 STALE-FOOD DYSPEPSIA. stretch. In Looshai, at first the European officers only got salted and preserved rations, and their health be- came seriously affected, whilst the preserved rations caused much palling of the appetite. As soon, however, as fresh provisions were brought up, the digestive disor- ders rapidly amended. The natural resources of Looshai were very poor, and sheep had accordingly to be contin- ually sent up to the troops. This campaign, Dr. Buckle emphatically stated, showed that the general health could not be maintained in the absence of fresh meat. Again, for men undergoing great exertion, never give only tinned meat for more than one day." According to British campaign experience, therefore, tinned foods, and foods otherwise pre- served, have a reputation that is not good, even if it is not decidedly bad. Again, on page 81, same work: "The great rules in the field are: (i) To thoroughly cook all meat, and boil all fluids, such as milk or water, served out to the men; and (2) to reject all food sup- plies wherever there is a doubt of their being fresh." That this has not always been done is shown by Duncan in his chapter on bowel complaints. 1 6. When water is contaminated with decom- posing animal remains, there can be no doubt at all that it contains the microbian life and the by- products which the decomposing organic struc- tures furnish; and when such water is ingested it is at least very unhealthy, if not always very dangerous. It happens sometimes that small .animals drop ON THE CAUSES. 289 into wells and remain there months, and even years, the water being in the meantime constantly used. Where the well is deep and the water is cold the animal remains may undergo but slow change, mechanical dissolution rather than mi- crobian decomposition, very unhealthy neverthe- less. In 1869, in a thickly-settled agricultural dis- trict, I witnessed a grasshopper plague. Every well in the district, I think, must have entrapped some of the insects even if covered over in a manner that would have been considered secure. Some of the wells must have entrapped a bushel or more of grasshoppers. And I remember see- ing about a bushel of grasshopper remains taken out of one of these wells three years afterwards, the water having been in constant family use in the meantime. During 1869, some time after the plague mentioned, there occurred a case of prolonged illness and death, from an affection of the bowels called "inflammation," in the family using the water of the well that I saw cleaned out The victim was a man thirty-five years of age, and the case occurred in late summer. Merely as an observer, I afterwards thought that the condition of the water was at least a contrib- utory cause, without which the case might not have terminated fatally. As an example of instances that have occurred, 290 STALE- FOOD DYSPEPSIA. and of the recurrence of which we are not always free from unforeseen danger, I quote from the San Francisco Call of August 27 and 28, 1895, the two items following: "LA PORTE, Ind., August 26. Three hundred persons were mysteriously poisoned at a Lutheran church festi- val held yesterday at Tracy, this county, where one thou- sand people had congregated to pay religious reverence on the occasion. "Those stricken suffered the most terrible agony, entire families succumbing to the strange disorder, the tortures of which were only alleviated after the arrival of phy- sicians. ' 'The symptoms of poisoning developed in most cases immediately after dinner, but last night and to-day there were numerous additions of victims to the fated list." "LA PORTE, Ind., August 27. The mysterious poison- ing of the three hundred persons at the Lutheran Mission festival at Tracy, Sunday, was caused by drinking water which was contaminated, but from what cause is un- known. The sufferers are in a fair way to recover, and it is not believed there will be any deaths." 17. The purity of water, in respect of animal and vegetable remains, becomes of the greatest importance in the tropics. Whatever one's busi- ness in the tropics may be, he should attend well to the water he drinks. Where the best that can be had is of doubtful quality, it should be filtered if convenient, and then by all means boiled. There should not be too long an inter- val between the boiling and using, else re- infection may take place. The day's supply ON THK CAUSES. 291 should be boiled on the same day, and until used it should be kept in clean and closed vessels, and in as cool a place as possible. According to facts recorded by Dr. Duncan, pages 123 to 125, there can be little doubt that infected water is about as dangerous to health, and even to life, as infected foods. Among sol- diers, infected water has caused a great deal of bowel complaint, and much loss of life. Ingested water infected with dangerous microbian life, may be more efficient as a cause of disease than when the same amount of microbian life infects an ingested quantity of solid food, owing to the circumstance that the water at the time dilutes the gastric juice, rendering it a less efficient germicide for the destruction of the microbian life, which may then possibly pass to the in- testine. 1 8. That foods which are, or have been, in- fected with microbian life to such an extent that the incidental decomposition is evident to the eye, to the nose, and to the tongue, are causes, when ingested, of disease and danger, has now been clearly enough pointed out, I believe. Enough has also been said, in my first essay, of the manner in which illness results from the de- composition of foods in the stomach and bowel; and the effects are not necessarily very different when decomposition has to some extent taken 292 STATIC-FOOD DYSPKPSIA. place before ingestion. By stale foods, I mean also some conditions of foods in which the infec- tion is not observable, but is nevertheless infer- able. For instance, in the tropics, where one's boots would turn green with " mildew " in twenty- four hours in a clothes locker, I hold that bread, pastries, cooked meats, etc., would become in- fected in a few hours anywhere outside of an ice chest, even though the infection might not be observable to unaided vision, or to the other organs of sense. So-called fresh butter is infected, because there is distributed through its mass a considerable decomposing remnant of the milk from which it was separated. Sugar, exposed too long in an open bowl, serves as a contrivance for accumu- lating spores and germs; and although sugar is not a medium from which microbian life can spontaneously develop, it preserves spores and germs for possible development in somebody's stomach and bowels. We may distinguish foods, in respect of the degree to which they are in- fected, as fresh, stale, and decomposing. There is, under ordinary circumstances, little danger of people eating foods in which decomposition is plainly evident to the senses. But danger lies in the use of stale foods, in which no decomposition, nor even infection, is evident to the senses. Some examples to be cited presently will show this. ON THE CAUSES. 293 Foods that are fresh and sound, are not exempt from infection by dormant spores or germs, at least to a minimum extent, as I have said at the beginning of this essay. The mouth itself is in- fested with microbian life. So that even when freshly sterilized foods are ingested, they can not reach the stomach without becoming infected on the way. But whenever any harm .results from this minimum of infection, it is the fault of the stomach itself, or of its owner, as we shall see. 19. During health, the stomach has the power of producing within itself an acid fluid known as the gastric juice. Only a small amount of gastric juice is present in the stomach when empty of food; but on the ingestion of foods, it appears in the amounts required, just as saliva appears in the mouth to the extent required. Normally all foods that enter the stomach are soon permeated by the gastric juice. Now, in a person of good health, the gastric juice is normally a sufficiently powerful disinfect- ant of the foods that are taken in. It is an effi- cient sterilizing agent, a powerful germicide. So that the microbian life that enters the stomach along with the foods is, under ordinary circum- stances, destroyed. Even those specific microbes to which infectious diseases are attributed, are destroyed by the gastric juice. For example, we are told that the microbes of typhoid fever, of 294 STALE- FOOD DYSPKPSIA. cholera, and of tetanus (locked jaw), die in less than one-half hour in normal gastric juice. Ordinarily the sterilizing efficiency of the gas- tric juice seems not to be impaired by being diluted with the amounts of liquid (if not cold) that are ingested with the foods. That digestion goes on perfectly when eating and drinking of hot fluids are simultaneous, is the best evidence that the two may properly go together. It may happen on voyages, expeditions, etc., that one has no choice but to subsist on foods of faulty condition. It is then well, especially if bowel complaints are occurring in the party, to allow the gastric juice to retain its utmost effi- ciency as a germicide, or sterilizing agent, and not to dilute it with drinks. Accordingly the drinking would be done with the greatest degree of safety half way between meals. This would be found quite easy after twenty-four hours' trial. 20. Other workers on this line of inquiry seem always to have overlooked the circumstances and conditions upon which efficient digestion depends. It is not strange, therefore, that much experimenting has not conclusively determined the truth of the statements I have just made on the germicidal property of the gastric juice. My statements are based on the grounds of circum- stantial evidence; and, of course, I am glad to find that experimental research is tending very ON THE CAUSES. 295 strongly to the same conclusion that the circum- stances indicate. The eminent bacteriologist, William H. Welch, says : " If we were to rely exclusively upon the results of experiments in the test-tube on the germicidal action of the acid gastric juice, particularly the very acid juice of the dog, we should consider this action a formid- able obstacle to the passage of many living bac- teria into the intestine." It has been determined, for example, that per- sons can get typhoid fever and cholera only when their intestines have become infested with the specific microbes of these diseases. It has also been determined that these particular microbes die in less than one-half hour in normal gastric juice. It may therefore be concluded that the passage of the infecting microbes to the intestine is due to some inefficiency of the stomach's function. But any one with a stomach in good working condition might get these diseases from drinking cold ^vater infected with the specific microbes. The cold water, for a time after its ingestion, would so dilute the gastric juice as to render it less efficient as a germicide. That those who attend to the sick of infectious diseases, in hospital wards or elsewhere, do not themselves become victims is probably due to some extent to the germicidal power of the gastric juice. 296 STALE- FOOD DYSPEPSIA. It must be as difficult for those who attend to numbers of the sick of infectious diseases to escape infection as it would be for the pistil of a flower to escape the pollen of the stamens. 21. Almost every case of infectious disease runs a part of its course before treatment is begun, during which time the infected discharges from the patient gain access to the air; and whether transported by flies, utensils, hands, clothing or bedding, or, in a dried state, drifted about by currents of air, the specific spores and germs gain access to the foods and drinks in quantities quite sufficient for infecting purposes. Even after the case is professionally conducted after the most approved theoretical plan, the safeguards employed are absolutely inefficient for the protection of those who are in necessary attendance upon the sick. The alleged segrega- tion, isolation, and disinfection do not achieve the results aimed at. There still remains a great difference, as usual, between what they are in- tended to do and what is actually accomplished by them. When persons are so situated that specific disease-producing microbes unavoidably enter their stomachs, and such persons do not become victims of the disease, it must be chiefly due to the germicidal power of the gastric juice. And this accounts for the exemption of most of those ON THE CAUSES. 297 who, in attendance upon the sick, are exposed to the dangers of infection. It remains to be determined whether the immunity of such persons from disease is not due to the good working condition of their stomachs; and whether it is not due to some functional inefficiency of their stomachs that some attendants fall victims to the disease. When stomach digestion is incomplete, we may assume that stomach disinfection is incom- plete; and where the one altogether fails, the other will fail also. 22. Of the gastric juice, on which digestion in the stomach wholly depends, "the quantity secreted in man in the twenty-four hours has been calculated at from thirteen to fourteen litres," about fourteen" quarts, a very liberal provision for thorough work on the part of the stomach, an efficient protection against the microbian invasion of the inner man. "The presence of food in the stomach causes a copious flow of the gastric juice," so that this fluid is always present when food is, both for digestion and for sterilizing purposes. But this is true only of the stomach which is performing its functions properly and vigorously; and there are many stomachs with which this is far from being the case too much of the time. On account of the ills they have, dyspeptics are yet liable to others they know not of. 298 STAI.K FOOD DYSPEPSIA. It is in the stomach of the dyspeptic, as we have seen him in the first and second, and will presently see him again in this third essay, that the disease germ escapes the destruction which is its normal fate, and survives to multiply its kind, to continue its work, decomposing foods that fail of digestion, and recomposing poisons in their stead. Not only in the stomach, but they are permitted to pass to the intestines to have their own way so far as they find material for the purpose; for the digestive fluids of the intes- tines, the bile and pancreatic juice, have but little if any germicidal power. We have seen, in the first essay, that the cir- cumstance of monotonous diet may cause the stomach to reduce its action very much, and sometimes almost or quite stop it. In the second essay we have seen that the stomach's action may be stopped entirely by the diversion of diges- tive energy for working purposes. And we can easily understand that when the stomach's action is much diminished, or suspended, and the supply of gastric juice does not appear promptly enough, or in quantity enough, any microbian life in- troduced will inevitably, not only continue its work of destruction of the food with which it is ingested and the construction of the incidental poisonous by-products, but will become much more vigorously active in the stomach than be- ON THE CAUSKS. 299 fore ingestion, owing to th-e much more favora- ble conditions of heat and moisture in the stomach than generally obtain outside of it. We see two conditions then under which in- fected foods are particularly unsafe. Both these conditions may prevail among soldiers monot- onous diet of stale or otherwise faulty foods; the excessive appropriation of energy for forced marching, or other excessively fatiguing work. The bowel complaints that are so destructive to armies on campaign duty are here held to be due to indigestion, which itself is due to monot- onous diet, diversion of energy, or stale and in- fected foods. 23. Generally, when a person is sick, he feels no requirement for food, and feels unable to ex- ert any force. He suspends work; even his lo- comotion and his thinking and talking may be suspended, for all these involve the expenditure of energy. Coincident with a sick man's disinclination to take food, there is a corresponding inability to digest it. And it seems that any food taken in excess of his felt requirement for it, will also be in excess of his power to digest it. It is a mischievous custom, this urging sick persons to eat in spite of any feeling to the con- trary; and to this custom is due much indiges- tion superimposed upon the ills the patient 300 STALE-FOOD DYSPEPSIA. already has. Not only is there repugnance to the quantity, but also, often, to the kinds and qualities of foods imposed upon patients. The custom is bad and productive of dyspepsia when the food is in good condition, and all the more harmful is it when foods are stale. The sick room is generally a warm place, and in it we often see remnants of foods kept for a whole day, or a whole night, which should by all means be kept in some cooler place outside. Milk and meat broths which have been in the sick room even two hours, at a temperature of seventy degrees Fahr M more or less, should not be trusted in the stomach of a patient. There is much feeding of stale foods in the sick room, and much harm is done, and the patient's term of ill- ness is prolonged, or his chances of recovery are diminished thereby. 24. Between vigorous health and absolute prostration by disease there are many degrees of illness. There occur many cases of illness with- out prostration many cases in which the person may still be able to remain at his duty. In such cases, however, there is a diminished capacity for work. There is less muscular and less mental energy available for work; and there is the same degree of depression of the working efficiency of the various organs of the body notably of the digest- ive apparatus. Although a man is still at his post ON THE CAUSES. 301 of duty, if he is ill, duty is extra hard. There is a diminished desire for food, and a corresponding decline of the power of digestion. It may be difficult to explain, but it is an ob- vious fact none the less, that cases of reduced digestive efficiency are often met with. They constitute a class of persons in whom digestion is good enough for all purposes so long as all the conditions of good digestion are strictly main- tained. Such persons can not commit the errors discussed in my first and second essays without suffering. Nor can they commit the error of in- gesting stale or infected foods without suffering Of this class of cases thus liable to suffer from in- digestion, there are many who, by virtue of cir- cumstance if not by choice, are consumers of foods that are stale or infected. And when for such offenses they suffer enough to require pro- fessional relief, they constitute the class whom I call the stale-food dyspeptics. 25. My classification in this essay, as in the two essays preceding, is made wholly with ref- erence to cause. Foods that are stale or infected, serve as the causes of the ills in the cases considered in this essay. The ills themselves may differ as much as the ingested substances differ. The ills may be very slight, or they may be fatal. In numer- ous instances the particular case is one of stale- food poisoning instead of indigestion. 302 STAI^-FOOD DYSPKPSIA. 1 have spoken of the depressed state of health as a condition upon which the operation of a cause of additional illness will sometimes depend. To be more specific, I consider the reduced effi- ciency of the digestive processes, especially the reduced amount of gastric juice produced during the depressed state of health in general, as the condition upon which depends the operation of stale food as a cause of indigestion. This/re- dis posing depression of health is sometimes evi- dent only from the circumstances of the case, namely, that the one or more items of the per- son's food, which are causes of his indigestion, have generally not caused him any trouble on the many former occasions of their use, and that some other persons use of the same foods at the same times, and do not in any manner suffer for doing so. To put my subject now into a more practical and concrete form, and to illustrate the bearings of what has so far been said in this essay, I will present a selection of representative cases, with such comment as may be necessary. 26. While serving as medical officer on a passenger steamship during the earlier part of my professional career, I was confronted one day with the task of treating a case of diarrhea. The patient was the second mate. I employed such means as are recommended in the books. ON THE CAUSES. 303 Each effort to cure resulted in temporary benefit only. The patient was on his feet at his duty every alternate watch of four hours day and night. After five days of unsuccessful attempts on my part, and a considerable decline in the pa- tient's strength, I concluded that the usual reme- dies were useless in that case, and I began seri- ously to look for the cause of the diarrhea in this man. I considered first his diet. He ate in the "officers' mess room." About fifteen others ate there also. A very few of these men were on duty every alternate four-hour watch; others were on duty four hours, and off duty eight hours. A few were on duty in the daytime only. The table was set at or near the hours of four, eight and twelve, day and night six times in twenty-four hours. The table was well sup- plied, and it did not occur to me to suspect or object to any item of food that this man ate, or that was on the table. At the hours of eight and twelve at night, and four in the morning, the table was set with cold dishes, but with hot tea or coffee. During the daytime most of the foods came direct from the stove; but there were al- ways some cold dishes, such as meats, breads, pies, cakes, the cooking or baking of which might have been done four, eight, twelve or more hours previously. And so of the cold dishes with which the table was exclusively set three times each night. 304 STAI^-FOOD DYSPEPSIA. At the time this case occured we were in tropical latitudes. The weather was warm, the air was moist. Fungoid growths found their best conditions for development. Our unused boots turned more or less green in our lockers. And there was a general tendency for every- thing not in actual use to get moldy. The human skin was constantly moist with perspira- tion, and some were itching and scratching, and it really seemed as if some fungoid vegetation was appropriating our skins as soil for its growth. What we felt we called prickly heat; techni- cally it is called liclien tropicus. It also occured to me that no microscope was necessary to prove that microbian life must have infested every item of food on the table of the officers' mess room that had not recently come from the stove, and to such an extent that actual decomposition must have made at least a vigorous beginning, even if not necessarily evident to the eye or the nose. Roast beef, for example, hot and fresh from the oven, was served on the cabin tables at five o'clock dinner. The intentionally large rem- nant of the same was served as cold roast beef on the officers' table every four hours until used up. Of other items not fresh from the stove were bread, pies, cakes; any and all of which, ON THE) CAUSES. 305 in such a climate, must become stale and infected in a few hours, not to mention twenty-four hours and more as the times of exposure of some of the foods used. It was a fact that the second mate's health had not been for some weeks of the most vigorous quality; it was concluded that his digestion was proportionately inefficient, and that, the cold dishes being thoroughly infected by microbian life, the decomposing changes, already actually begun, continued in the stomach and made too much progress before sterilization by the gastric juice was accomplished. It was assumed that some one or more of the decomposition products served as purgatives and caused the diarrhea. This may not have been the whole truth of the case, but the diarrhea immediately stopped when the patient's food was sterilized. He was simply directed to eat nothing but what had very recently come from the stove, and if there were things on the table that he wanted which had not come very recently from the stove, he was to have them well heated on a plate in the oven before using them. All the bread he used was either absolutely fresh, or it was toasted to order for him in the oven. The treat- ment therefore consisted only of the sterilization by heat of everything he ate. It was an abso- lutely complete and prompt success. Three 20 306 STALE-FOOD DYSPEPSIA. years later I had a case, a third mate, under circumstances precisely similar to those of the case just cited, except that no time was lost in finding the cause and applying the remedy and obtaining prompt and complete relief. 27. A child two years of age, previously in perfect health, seemed to feel unwell during afternoons and evenings, complained of pain in the abdomen, ate less than usual, was cross, irritable and peevish, whereas it had usually been cheerful and lively. This had been the case for three weeks, during which time the child had grown perceptibly thinner. There was no specially definable or namable illness discover- able on examination of the cJtild, but, on looking into the circumstances of the case, the cause was easily determined. The milk supply came to the family in the early morning; it came from a dairy about forty miles from the city, on the previous evening, and I suppose it was no worse than other milk that is delivered in large cities. This child had of this milk at meal times and between meals, and had a last drink of it previous to being put to bed in the early evening. With some difficulty the mother was induced to give none of this milk to the child later than at the noon meal, and to let the child use it only sparingly at noon. By noon this milk was considered suspiciously stale, and later than noon ON THIS CAUSES. 307 it was regarded as undoubtedly stale and in- fected and as being the cause of the child's ill health. Until noon it was considered safe enough, though by no means first rate. Within a single day the child resumed its accustomed cheerfulness. After a few weeks, milk was again used as before, with illness again resulting. It was again restricted according to directions, with immediate recovery of health and speedy recovery of the child's accustomed weight. The results confirmed the opinion that the case was one of stale-milk dyspepsia. 28. From an interior town, in a rather warm part of the state, was brought a girl aged sixteen years, extremely thin but of large frame for that age. According to the collective opinion of a dozen doctors, this was a case of hysteria. She had been in an utterly disabled condition for two years, excepting a temporarily improved condi- tion for two months half a year previous to her coming to the city. She had been an irregular sufferer since ten years of age, and was always out of school one- fourth of the time on account of her illness. When this case came to my house she could not walk alone. She had a little strength in the o forenoon and could then feed herself, but in the afternoon could not raise and hold a glass of water to her lips. She shed an unnecessary 308 STALE-FOOD DYSPEPSIA. flow of tears occasionally for the simple reason that she was powerless to restrain them. When I learned that hysteria was the title acquired by this case, I concluded and asserted that dys- pepsia was at the bottom of it, and that I would take her for one month at my house, cure her of dyspepsia in a very few days, of the dependent "nervous" ills also, and restore to her, in the thirty days, vigorous digestion, and a proper amount of flesh, blood and strength. All which was accomplished in August, 1894. The circumstance that a case is alleged to be hysteria is evidence to me that it is a case of dyspepsia, with the so-called hysterical manifes- tations as dependent phenomena. But before I had seen this case, and after I had offered to take her, I learned from her mother some facts which confirmed my conclusion. The mother had long ago been directed to make the girl's diet mainly of milk. And she did so; but she seemed not to know, and seemed not to have been instructed on, the importance of having the milk always in a good state of preservation. She got her milk supply in the morning. The region where she lived was very warm. She kept no ice, but suspended the tin of milk in a shallow well and hauled it up at various times as required during the day. This milk was fresh only in the early part of the forenoon, and ON THE CAUSES. 309 stale during the rest of the day. Milk diet under such circumstances, long continued, was cause enough for the exceptionally bad condi- tion in which this girl was brought to us. Her spontaneous improvement, half a year before coming to the city, was during the coldest part of the year, and coincides with the better condi- tion in which milk may easily be kept during such weather. The treatment of this case consisted in depriv- ing the patient of milk altogether for a month, and otherwise feeding her just as we would have done had she been a vigorous girl of sixteen in perfect health, except that everything she ate and drank wasfres/i. In much less than a week her tongue resumed its natural condition and color, her foul breath disappeared, her bowels moved unaided, and for the first time in six months she resumed her menses all without drugs. 29. A storekeeper had been suffering ten days from acute dysentery. It was found on inquiry that he had during this time been daily eating a moderate amount of what he called "old English cheese." No other item of his accustomed food being suspected, he was re- quired to abstain entirely from that cheese, whereupon he immediately recovered his health. 30. From the San Francisco Chronicle (date not preserved) : 310 STALE- FOOD DYSPEPSIA. "A FATAL DRINK." "Little Walter Warren, of East Oakland, died yesterday from the effects of drinking ice-cream soda. The boy was delicate, and drank the ice-cold soda after a meal. The stomach became chilled, digestion ceased and the child died in convulsions." The condition or quality of this fatal drink seems not to have been taken into account. The chilling of the stomach and the temporary stop- ping of digestion do not kill. That the child died in convulsions was a circumstance which alone should have cast strong suspicion on the cream as the source of the poison which caused the convulsions and death. 31. From the San Francisco Chronicle, July 5, 1892: "ICE CREAM'S DEADLY WORK." "COLUMBUS, Ind., July 4. Last night at a church festival at Hope, twelve miles from here, forty people were seriously poisoned by eating the ice cream that was served, among whom were two prominent physicians." From an editorial of the same paper, July 6: "Why the attempt to spread the gospel in such a por- tion of the country as Indiana should be hampered and prevented by such untoward obstacles, is one of those mysteries which are past finding out. There can be no doubt but that the church festival was for some laudable purpose, though its precise object is not stated, and to the feeble eye of human understanding there is no assignable cause for the sudden illness of forty people who were en- gaged in a worthy enterprise. Ordinary ice cream, such as ON THE CAUSKS. 31! is made at home or purchased from the confectioner, is not likely to produce such effects. ... It has happened that more than once at church festivals and Sunday school picnics and fiestas of that kind the same phenomenon has been witnessed, but the cases are not numerous enough as yet to deduce a general rule from them. Whether there be any occult connection between the character of the entertainment and the dangerous effects of the ice cream, or whether the misadventure may be accounted for by purely natural causes, who can say?" Had a few of these forty people been killed, the coroner's jury would most likely have found, by retracing the history of that cream from the hour of its ingestion to the moment of its pro- duction from the cow at the one or more dairies or farms that furnished it, or donated it, that it was at the time of freezing in a bad state of preservation. The dairy methods, the dairy men, the church committee, the makers, custodians, and dispen- sers of the ice cream, the local conditions of the weather at the time, etc., should all be carefully considered on such occasions. In reference to the milk, cheese and cream involved in the last five cases cited (three from personal observation, and two of public notoriety), I repeat, for pur- poses of explanation, from Dr. Wm. H. Welch, that "in certain cases of poisoning with milk, cheese, and ice cream, Vaughan has demon- strated a toxic ptomain which he calls tyrotoxi- con." 312 STALE-FOOD DYSPEPSIA. 32. A Frenchwoman, having symptoms of dys- pepsia and suffering from hysteria, was found to have for a long time been using claret wine that was suspected to be of inferior quality. This wine was the only thing suspected as caus- ing the dyspepsia and the dependent hysteria. The use of the wine was stopped and the dys- pepsia and hysteria immediately subsided also. Two years later the same woman was again ill with the hysterical element most conspicuous. It was found that she had recently resumed the use of the claret. The claret was again stopped, with complete recovery as the prompt result. Another Frenchwoman, who was an habitual but moderate consumer of the same quality of claret wine, had also a child at the breast. The mother was well, but the child was a considera- ble sufferer from indigestion. Nothing else be- ing reasonably suspicious as a cause, the claret was stopped, and the child recovered as promptly. Prof. E. W. Hilgard says that a great deal of claret that is inferior, from the fact of having been badly made, contains a substance called mannite. To many persons this mannite is so purgative as to prevent their use of the qualities of claret containing it. If the acetification of claret is not certainly a cause of digestive disturb- ance, the presence of mannite sometimes is. And if these cases of dyspepsia were not due to ON THE CAUSES. 313 deteriorated beverages, they may have been due to inferior ones. (Good claret, or any good wine, may also cause dyspepsia in the manner explained in the first essay.) 33. From the San Francisco Chronicle, June, 1892: "POISONOUS SHELL-FISH." "Jean Pierre Berger died yesterday at the Gailhard Hotel, of which he recently became the lessee, as a re- sult of poisoning caused by eating shell-fish, some say mussels and others crawfish." "Mr. Berger was well known in the French colony, having resided in California about twenty years. He was originally a cook." There being no question as to the wholesome- ness of such shell-fish as people are accustomed to eating, and as to the safety of anybody that eats them under ordinary circumstances, it only remains to conclude that in such cases as this the shell-fish were in a faulty condition. The danger in such cases is all the more apparent from the circumstance that this man had been a cook, and would have been expected to be able, when that was possible, to recognize dangerous faults in foods. We can understand such cases very much better after learning from Welch that- "Many articles ofybr^/ afford excellent nutritive media for the growth of a number of species of pathogenic (disease producing) bacteria, and this growth may occur without ap- 3H STALK-FOOD DYSPEPSIA. preciable change in the appearance or taste of the food. The danger from infection from this source comes into consid- eration for uncooked or partly cooked food, and for food which, although it may have been thoroughly sterilized by heat, is allowed to stand a considerable time before it is used." 34. From the San Francisco Chronicle, Octo- ber 15, 1894: ''POISONED BY MUSSELS." "Albert Gotzsch, the German who was poisoned by eating mussels last week at Fort Ross, has recovered. He is at the German Hospital, where he was taken im- mediately after the poison manifested itself. It will be remembered that Gotzsch's wife died from eating the mussels. Of late several people have eaten mussels found near Fort Ross, to their sorrow. More than seven cases of poisoning of this character have been reported within the last few months." And more cases have occurred than have been reported. Even though the circumstances seem strongly to indicate that a person has been poisoned by the mussels he has eaten, it may not be true that the mussels were poisonous. In at least some of the cases of alleged mussel poisoning that oc- curred in the summer of 1894 in the vicinity of San Francisco, the suspected mussels were be- yond all doubt fresh, and there seems to be a better prospect of finding the cause of the poison- ing by looking into the condition of the victim at ON THE CAUSES. 315 the time, and the circumstances under which he ate the mussels. The fresh mussel is, however, under some cir- cumstances, not above suspicion. Intelligent and long experienced dealers of the fisherman's produce contend that it is unsafe to eat mussels that are taken from the rocks at low tide during warm weather and the full moon. There is, very likely, some truth in this view of the fisherman, but whatever it may ultimately prove to be, is yet to be determined. In the cases of twelve persons who suffered from eating mussels in this vicinity during the summer of 1894, it is learned that the mussels were fresh, but were gathered under the very conditions which the fisherman regards as un- safe. For at least forty-eight hours the north wind had been blowing, and the air had been un- usually warm day and night. The moon was full, and the tide was low. That the water was also unusually warm was shown by the very un- usual phenomenon, for this locality, of phosphor- escence during the previous night, and also on the same night that the mussels were eaten. These twelve who suffered from eating mus- sels were of a party of fourteen, there having been two of the fourteen who did not suffer at all. Two were dangerously ill, and ten were variously ill in less dangerous degrees. 316 STALK-FOOD DYSPEPSIA. Of the two who escaped illness, it has been learned that they were free from faults of diges- tion. The two who were dangerously ill have been seen. Both are in occupations which predispose to capriciousness of the digestive function and favor the development of disorders of digestion. Both these men, according to their own statements, were subject to disorders of digestion. From these same two gentlemen it was learned that during an afternoon they went eight miles on foot over a very hilly road; that this laborious tramp of three hours was followed by a good appetite and a good dinner at about seven o'clock, and at nine o'clock by a supper exclu- sively of mussels, and by going to bed a half hour later. With a good dinner at seven o'clock, they could not have been hungry at nine, and the mussels at that hour must have been in excess of the bodily requirement in the way of food. The error of overeating was therefore committed and would have been trivial in the case of any- body but a dyspeptic, and at any other time than just before going to bed, and for any other than those highly nitrogenous foods which are so capable of speedy decomposition into deadly poisonous products when for any cause digestion is inefficient. ON THE CAUSES. 317 35. From the San Francisco Chronicle, July 30, 1891 : "POISONOUS MEATS." "On Saturday last, a butcher at Loomis, Placer County, threw upon the local market some pressed corn beef. It was nice to look at and pleasant to taste, but it came nearly ending the earthly careers of a number of the residents of the great fruit belt; in fact, one death has already resulted therefrom, and others may occur. "Among those who partook of the poisonous meat were A. Free, wife and child. The child died yesterday, and Mr. and Mrs. Free were not out of danger at last accounts. "E. V. Maslin . . . ate of the meat and was seized with most violent cramps. He was in great agony for several hours, but finally recovered. "G. W. Ellery was similarly attacked soon after eating the meat. He fell in a dead faint from sudden and severe pain, striking upon and somewhat disfiguring his face." "Mr. Owen and wife, of Penryn; Mr. Mason and wife, of Newcastle; Colonel Grove and wife, of Loomis; and four young Englishmen of the citrus colony are all down from the effects of partaking of the pressed beef, and it is not unlikely that other fatalities will be reported." I learned, from one who is named in this extract, that this corned beef was prepared by the butcher who retailed it, that it was not canned. The arrest of the butcher took place, but was not followed by prosecution. (See quotation from Welch, page 313.) On this case of meat poisoning I sought an explanation from my 3'lS STALK-FOOD DYSPEPSIA. butcher. He is a German. The butcher's art where lie learned it was subject to some strict legal regulation, pertaining not only to the con- dition of his meats when dispensed, but also to the sanitary condition of his animals before slaughtering. This butcher was of the opinion that this corned beef was made from an animal that was diseased at the time it was slaughtered. I am told of a case in which about fifty miners became ill just after eating of fresh beef; but, during the five or six hours just preceding slaughter, the animal had been hurriedly and harassingly driven, and the weather was very warm. The action of the animal had been extraordi- nary and prolonged, its incidental tissue wastes were great in proportion. Elimination of these poisonous wastes, these ashes of animal combus- tion, had not had time to occur. The processes of excretion may even have been earlier sus- pended more or less completely, for want of energy to keep them going, because the animal's all and utmost energies were required for locomotion. The excessive amount of retained wastes rendered the flesh poisonous to the men who ate it. . 36. From the San Francisco Chronicle, March 3' ON THE CAUvSES. 319 "THE RESULT OF EATING A MUSHROOM." "There are two unfortunate people residing at 258 Clementina Street. In one instance, that of the husband, the torture may be said to have almost become bear- able; but in the other, that of the wife, death could have no sting more agonizing than the suffering which she is undergoing. "The sufferers are Gabriel Lagrave and wife, who ate two mushrooms which they gathered in Golden Gate Park. They spent last Sunday morning there in a most domestic manner, taking along with them a well-filled lunch basket and the Frenchman's indispensable bottle of claret, "On their return trip they discovered the mushrooms and ate them that evening stewed in olive oil. There is where the trouble and strangeness of the whole thing be- gan. . . . Monsieur Lagrave was the first to feel the effect of his evening meal. Certain rumblings in his insides, pains in hi? joints and elsewhere, accompanied by effective nausea, appeared on Monday. On Tuesday he was ill, and to this day he has not quite recovered. "Madame Lagrave did not begin to feel her discomfort until late on Tuesday night. Then she began to ex- perience the terrific pains which she is still suffering. Nearly all her bodily functions have ceased and her extremities have turned cold and blue." The physician who attended these cases, speaking to a reporter, on mushrooms, said: "If culled in damp weather they are likely to be poi- sonous. They are no better if they are allowed to wait over too long before being cooked, and when once cooked they are positively dangerous when warmed over to be eaten at another time. In all the physician's state- ments he is backed up by his books and medical ex- 320 STALE-FOOD DYSPEPSIA. perience. The authorities in most cases give it out that all fungi are poisonous, while in some cases the poison- ous kind are stated as only the 'toadstools' that grow from decayed vegetable matter. "At any rate, it remains as a sad fact for lovers of the succulent mushroom that it will keep him guessing some time whether or not his pet dish may turn on him after having partaken of it, for it frequently occurs that the uncomfortable intestinal pains and nausea do not occur for several hours, and sometimes three days." According to the physician quoted, poisoning may result from eating the proper mushroom in a bad condition. This, however, according- to Prof. E. W. Hilgard, is exceptional. The Pro- fessor holds that it is generally the itrong mush- room that is poisonous. 37. From the San Francisco Chronicle, July 27> 1893: ''DECAYING VEGETABLES CAUSE DEATH." "SAN JOSE, July 26. A nine-months-cld child of G. W. Condoan, that died recently, has been declared by J. W. Wayson, the attending physician, to have been poisoned by the odor arising from a lot of decaying fru't in a neighboring drier. The stuff had been covered up for a year, and the stench that arose when it was again exposed to the air made several adults ill. The child died with every symptom of poisoning. A constable, under the direction of the supervisors, abated the nuisance." This was not a case of poisoning by infected food, but it is none the less interesting and to the ON THE; CAUSES. 321 point, for it shows that some of the by-products of decomposition are volatile in warm weather, and that the same are so powerfully poisonous that, even when greatly diluted with the air we breathe, one can absorb a fatal dose of them through the lining membrane of the lungs and air passages. LIVE-STOCK POISONING. 38. In the year 1880, a farmer in San Benito County, California, undertook to preserve fodder by the method called ensilage. The object was to have fodder for use during the dry summer and autumn in the fresh green and succulent condition in which it was cut in the spring. For the purpose of preserving fodder in the green state, it is packed immediately after being cut, into room-like spaces inclosed by solid concrete walls without roof. The top is made like that of a haystack, not being protected nor sealed itself, but serving to protect and seal up that which is beneath it. Now ensilage, it seems, can succeed, if at all, only where there is a cold season during which the preserved fodder is to be used. Even if the preservation of green fodder, as such, could be successful in California, it is required for use during seasons that are either very warm or at least not cold. When therefore the silo, or in- 21 322 STALE-FOOD DYSPEPSIA. closure, is opened, the temperature is such as to favor the very rapid growth of fungus upon and at the expense of the fodder. Simply stated, the fodder would become moldy at a much more rapid rate than it would be required for use under ordinary circumstances. However successful Mr. Green, of San Benito County, may have been in preserving his fodder, it had not long been unsealed, and had been fed but a few days, when something like a dozen horses took mysteriously sick and died, at which time also the ensilage was observed to be getting very musty. Poisoning was the theory, but quite another kind was suspected, until Professor Hilgard, of the College of Agriculture, on a single glance at a moldy specimen of the fod- der, at once declared that the moldiness was cause enough for the death of the animals to which fodder in such condition had been fed. The specimen was examined, however, for the presence of poison that was suspected to have been applied with criminal intent. But not a trace was found. In this connection it may be stated that moldy carrots are poisonous, and stockmen dare not feed them for that well-known reason. What is known as ergot, or "smutt," on hay tends to produce abortion in cows to which hay so infected is fed. ON THE CAUSES. 323 Hay infected with "rust" is known among horsemen to be dangerous fodder. ''Smut" and "rust" are examples of very small parasitic plants growing upon our cultivated cereals and at their expense. And the poison of these parasitic growths is in themselves and not, as usual, in any by-products of their growth. 39. From the San Francisco Chronicle, July 18, 1893: "A MOTHER AND THREE CHILDREN DIE FROM POISONING." "NASHUA, N. H., July 17. A sad case of mysterious poisoning is reported in the family of Theophile Des- champs, evidently from something in the food, the nature of which is still unknown. The family consisted of father and mother and six children. Three children are dead, and the mother can not live." The science of organic-decomposition poisons is still in a rudimentary state of development, and that small share of it which has so far taken any practicable form in the every-day medical practitioner's mind does not yet furnish a satis- factory explanation to every case of illness or poisoning from infected foods. Hence, cases now and then in which poisoning is clearly evi- dent, like the one just quoted, are allowed to pass unaccounted for. Still less satisfactory is the explanation, if any is made at all, when only a single life has been lost. A man dies at an age 324 STALE-FOOD DYSPEPSIA. when death is certainly premature, and under circumstances which make death a most unex- pected and unthought of event, and we read of him that " he had been ill for only two days with a stomach disorder." 40. It will be observed that dyspepsia as a re- sult of the use of stale food, milk for example, may continue for a long time. And it is very likely to continue as long- as the doctor calls it hysteria, as in a case cited. Along with stale-food dyspepsia, whether of short or long duration, we will find about all the various dependent ills that have already been sufficiently explained, as also their relation to dyspepsia, mainly in the first essay, and also in the second. When a plain case of dyspepsia is called hysteria, it need not be surprising that others should be called nervous exhaustion, or heart disease, etc. ON THE SUMMER DYSPEPSIA OF YOUNG CHILDREN. 41. Of all sufferers from stale-food dyspepsia, the largest and most important group consists of that very large number of young children who are victims every summer of what is called sum- mer complaint, summer diarrhea and cholera infantum. These cases are stale-milk dyspep- sias. They are almost exclusively diseases of SUMMER DYSPEPSIA OF YOUNG CHILDREN. 325 cities, and of the summer season. They are most numerous where and when the weather is very warm and the air is very moist. They come with that hot, sultry weather during which the fatal sunstroke is a frequent occurrence. This summer dyspepsia of young children^ as I prefer to call it, is present when perishable foods are most perishable; it is present when milk is not good at the moment of delivery in large cit- ies, and dangerously bad too soon after delivery to families who do not make diligent and intel- ligent use of ice. This must be true of milk, even if pure and delivered under the most favor- 'able circumstances that are practicable during the warmest months, for example, in New York City. More certainly and generally is it true of cheap milk delivered in cities to poor people. Every farmer's wife knows that there is such a thing as sour milk which is not unhealthy, and which can be and is used as food, either alone in the raw state, or in combination with other things to be cooked, as in bread and pastries. Nor is the idea of danger associated, in the minds of country folks, with the ingestion of sour milk from a well-managed dairy. But there is something different, and some- thing dangerous, about the retrograde change that so frequently takes place in the milk after deliv- ery in the city during warm weather. On the 326 STAI^-FOOD DYSPKPSIA. one hand, in a clean, cool milk-house, the fresh milk is exposed in a clean pan, to clean fresh air, and a simple acid fermentation takes place, with no resulting products that are prejudicial to the health of the consumer. On the other hand, under entirely different conditions, there seems to occur a more complex process of change, with resulting products that are not only prejudicial to health, but may actually be dangerous to life. 42. In the matter of dyspepsias, physicians have attended to the phenomena rather than to their causes. The resulting phenomena are nu- merous, inconstant and not amenable to any use- ful classification, "There are a great many kinds of dyspepsia," said a late president of the Medi- cal Society of the State of California. And Dr. J. Lewis Smith, of New York City, in a large text-book on diseases of children, devotes five chapters to diseases of the stomach and bowels of infants and children, and uses ten or more terms to distinguish what the medical profession considers to be as many more or less distinct diseases, or diseased conditions. In the class of cases under consideration, we have distinct causes in the infected conditions of the foods, and the results are indigestion, with its usual varied and numerous phenomena, for all of which the general term stale-food dyspepsia is SUMMER DYSPEPSIA OF YOUNG CHILDREN. 327 quite sufficient. But as it may be well and con- venient to distinguish the infantile from the adult, and to specify in the term the annual city visitation, we may designate this class of cases as the summer dyspepsia of young children. 43. It has been well enough established as a general fact that the ingestion of stale and in- fected foods may cause dyspepsia, and enough has elsewhere also been said on the manner in which such foods produce illness. My object here is simply to show what I hold to be the cause of this summer dyspepsia of young chil- dren, but not to discuss any of the resulting phenomena of dyspepsia itself. I will now present some extracts from the sixth edition of Dr. J. Lewis Smith's work on "Diseases of Children: " In New York City, "fifty-three per cent of the total number of deaths occur under the age of five years, and twenty-six per cent under the age of one year." Making liberal allowance for statistical errors, Dr. Smith thinks "It may safely be stated that one-fourth of the children born in this city die before the age of five years" (page 24). 44. "It is in infancy, and especially in the first year, that the use of unwholesome food entails the most serious consequences. No artificially prepared food is a good substitute for the mother's milk, and hence, artificial 328 STALE-FOOD DYSPEPSIA. feeding ot the infant, unless under the most favorable circumstances, results disastrously. ' 'In the country, where salubrious air and sunlight con- spire to invigorate the system, where a robust constitu- tion is inherited, and where cow's milk, fresh and of the best quality, is readily obtained, lactation is not so neces- sary for the well-being of the infant; but in the city its importance cannot be too strongly urged" (p. 27). To the "cow's milk, fresh, and of the best qual- ity" is due the bottle-fed country babe's immu- nity from the illness which during the warm months almost certainly kills the city bottle-fecl babe, because the cow's milk is not fresh and of the best quality in the city. 45. "The foundlings of cities afford the most striking and convincing proof of the advantages of lactation [the ad- vantages of fresh, natural milk, I should say]." "In some cities foundlings are wet-nursed, while in others they are dry-nursed, and the result is always greatly in favor of the former. Thus, on the Continent, in Lyons and Parthenay, where foundlings are wet-nursed almost from the time they are received, the deaths are thirty-three and seven-tenths and thirty-five per cent. On the other hand, in Paris, Rheims and Aix, where the foundlings were wholly dry-nursed, at the date of the sta tistics their deaths were fifty and three-tenths, sixty-three and nine-tenths and eighty per cent." "In this city the foundlings, amounting to several hundred a year, were formerly dry-nursed, and, incredible as it may appear, their mortality with this mode of alimentation nearly reached one hundred per cent. Now wet-nurses are em- ployed for a portion of the foundlings, with a much more favorable result" (p. 27). "These facts, to which others might be added from the SUMMER DYSPEPSIA OF YOUNG CHILDREN. 329 experience of European cities, show the importance of lactation as a means of reducing infantile mortality in the cities. What has been stated as regards the results of artificial feeding of foundlings is true, in great measure, in reference to all city infants'' (27). "In infancy . . . the mortality is largely increased by improper diet, while in childhood the diet is a much less common cause of death" (28). 46. The non-committal expression, "improper diet," so common in the writings and sayings of physicians, conveys to a dyspeptic some confu- sion and no good. Though the expression may circumscribe the truth, patients and parents not only utterly and always fail to grasp it, but get erroneous and misleading ideas instead. The "improper diet" that is so fatal in cities to artifi- cially fed infancy, is milk that is stale and infected. And "in childhood the diet is a much less com- mon cause of death," because stale milk is little or no part of it. "Indigestion is more common during infancy than in any otherperiod of life," says Dr. Smith, on page 697. And I will add, because it is the only period of life when there is danger of an exclu- sive and prolonged stale-milk diet in cities. "During the summer months it often happens that an infant in the city cannot digest properly any food given to it except the mother's milk, and from this results much of the infantile sickness and mortality which make this season of the year much dreaded by parents" (698). 330 STALE-FOOD DYSPEPSIA. I suggest that in such cases the infant's al- leged inability to digest is only apparent on the usual superficial examination of the circum- stances of the case. And I hold that a more comprehensive study will reveal no original fault of the infant's digestive apparatus, but it will re- veal the fact that the mother's milk is the only non-infected (sterile) food that the infant receives; whereas the other infant foods, during the sum- mer months, among poor or careless people, are in such a state of infection that the processes of decomposition, after ingestion, proceed in ad- vance, and, by their disastrous results (effects of the decomposition products on the patient), may prevent any digestion from taking place at all. 47. If the well-known character of city milk, in the houses of poor or careless people, during the hot months, is borne in mind, the following additional extracts from the work of Dr. Smith will show plainly enough that it is the infected condition of the perishable foods ingested, milk chiefly, that is the cause of the summer dyspep- sia of young children: ' 'The most common cause of indigestion in the infant is artificial feeding. This, in the cities, is productive of a great amount of gastric and intestinal derangement and disease. The younger the infant, the less frequently does it thrive if brought up by hand" (698). * "In spite of any care, and of any selection of milk or other food, there is seldom that healthy nutrition which is observed in infants who receive the breast milk." SUMMER DYSPEPSIA OE YOUNG CHILDREN. 33! "The 'swill milk' in common use among the poor families of this city is totally unfit for the feeding of infants" (698). "Habitual indigestion is, as might be expected, more common and severe in artifically fed infants than in those at the breast." "In rural localities where children are much of the time in the open air, have good constitutions, active digestions, and fresh food, dyspepsia is comparatively rare, but in large cities, in which the conditions of life are so different, its occurrence is common" (700). "Dyspepsia often rapidly disappears by hygienic measures without the use of medicines*, as by removal from the city to the country. . . . "In infants, also, marked improvement is often ob- served on the approach of the cool and bracing weather of autumn and winter" (704). "Gastritis, as I have observed it in infants, has been in most cases due in great part to the continued use of im- proper food. . . . "Milk, acid or otherwise unwholesome, farinaceous substances; stale or of an inferior quality, and not properly prepared, . . . may be specified among the causes. "Therefore this disease is most common in bottle- fed infants, and is comparatively rare in those who re- ceive abundant and wholesome breast milk" (705). 48. "In rural districts infantile diarrhea is not so prevalent and fatal as in cities. In the farming sections it does not materially increase the death-rate, and it is, therefore, not so important a malady as in cities. In cities it largely increases the aggregate of deaths. Es- pecially fatal is that form of it which is known as the summer epidemic, as is shown by the mortuary records * Does it ever disappear with the use of medicines? 332 STALK-FOOD DYSPEPSIA. of any large city. Thus, in New York City, during 1882, the deaths from diarrhea reported to the health board, tabulated in months, were as follows: Under Over five years. five years. January 34 14 February 32 15 March 50 14 April 50 20 May 72 15 June 231 19 July i,533 131 August 817 149 September 362 84 October 195 55 November 68 31 December 35 24 "It is seen that in 1882, in New York City, the deaths from diarrhea under the age of five years were greatly in excess of the number during the whole period of life subsequent to that age" (719). Many cases of summer diarrhea linger as long as three or four months (July to October) and then die, which fact explains the greater number of deaths in October than in May (721). 49. "In their annual report for 1870 the board states: 'The mortality from the diarrheal affections amounted to two thousand, seven hundred and eighty-nine, or thirty-three per cent of the total deaths; and of these deaths ninety- five per cent occurred in children less than five years old, ninety-two per cent in children less than two years o!d, and sixty-seven per cent in those less than a year old.' Every year the reports of the Health Board furnish similar statistics, but enough have been given to show SUMMER DYSPEPSIA OF YOUNG CHILDREN. 333 how great a sacrifice ot life infantile diarrhea produces annually in this city. "What we observe in New York in reference to this disease is true also, to a greater or less extent, in other cities of this country and Europe, so far as we have reports. . . . In country towns, whether in villages or farm houses, this disease is comparatively unimpor- tant, inasmuch as few cases occur in them, and the few that do occur are of mild type, and consequently much less fatal than in cities" (719-720). And there is a corresponding difference in the quality of the milk employed in the bottle-feed- ing of infants. "Unsuitable food" is frequently referred to, but it is never explained in what respect the food is unsuitable. No special fault is. specified. 50. "The fact is therefore undisputed, and is univer- sally admitted, that the summer season, stated in a general way, is the cause of this annually recurring diarrhea epidemic, but it is not easy to determine what are the exact causative conditions or agents which the summer weather brings into activity. That atmospheric heat does not in itself cause the diarrhea is evident from the fact that in rural districts there is the same in- tensity of heat as in cities, and yet the summer complaint does not occur. The cause must be looked for in the state of the atmosphere engendered by heat where un- sanitary conditions exist, as in large cities. Moreover, observations show th:it the noxious effluvia with which the air becomes polluted under such circumstances con- stitute or contain the morbific agent" (721). 51. Then Dr. Smith, on the same page, cites instances of the coincident prevalence of infantile 334 STALE-FOOD DYSPEPSIA. diarrhea and an extremely filthy city atmos- phere during warm weather, and assumes, per- haps correctly, that the filthy air is or contains the cause of the diarrhea. But under the filthy conditions detailed by Dr. Smith, one cannot find diarrhea among all the "dense popu- lation . . . poor, ignorant and filthy in their habits," except among the young children The adults are not even unhealthy, but are among the healthiest people of the city. While some of the men may be out-of-doors much of the time, the mothers at any rate get no better air than their children. And as in one filthy localty "nearly every infant between two ave- nues had diarrhea, and usually in a severe form, not a few dying," and in another foul locality "the summer diarrhea was very preva- lent and destructive to human life," the truth as to cause may certainly be so far circumscribed as to be sought only in the local conditions and circumstances of the infant life. "Every physician who has witnessed the summer diarrhea of infants is aware of the fact that the mode of feeding has much to do with its occurrence. A large proportion who each summer fall victims to it would doubtless escape if the feeding were exactly proper." 52.. "In New York City, facts like the following are of common occurrence in the practice of all physicians: Infants under the age of eight months, if bottle-fed, nearly always contract diarrhea, and usually of an obstinate SUMMER DYSPEPSIA OF YOUNG CHILDREN. 335 character, during the summer months. The younger the infant, the less able is it to digest any other food than breast milk, and the more liable is it therefore to suffer from diarrhea if bottle-fed. In the institutions nearly every bottle-fed infant under the age of four or even six months dies in the hot months, with symptoms of indi- gestion and intestinal catarrh, while the wet-nursed of the same ages remain well" (724). The wet-nursed get fresh milk; that is the fundamental difference. ' 'The second summer is the period of greatest danger to infants because most infants in their second year are table-fed, while in the first year they are wet-nursed. Such facts, with which all physicians are familiar, show how important the diet is as a factor in causing the sum- mer complaint" (724). 53. There is great difficulty "in a large city in obtain- ing proper diet for young children, especially those of such an age that they require milk as the basis of their food. Milk from cows stabled in the city, or having a limited pasturage near the city, and fed upon a mixture of hay with garden and distillery products, the latter often predominating, is unsuitable. ... If the milk be obtained from distant farms where pasturage is fresh and abundant and in New York City this is the usual source of supply considerable time elapses before it is served to customers, so that, particularly in the hot months of July and August, it frequently has begun to undergo lactic acid fermentation when the infants receive it. That dispensed to families in the morning is the milking of the previous morning and evening." "The use of this milk in midsummer by infants under the age of ten months frequently gives rise to more or less diarrhea." "The ill success of feeding with cow's milk has led to the preparation of various kinds of food which the shops contain, but no dietetic preparation has yet ap- 336 STALE-FOOD DYSPEPSIA. peared which agrees so well with the digestive function of the infant as breast milk, and is at the same time sufficiently nutritive." 54. "In New York City, improper diet, unaided by the conditions which hot weather produces, is a common cause of diarrhea in young infants; for at all seasons we meet with this diarrhea in infants who are bottle-fed; but when the atmospheric conditions of hot weather and the use of food unsuitable for the age of the infant are both present and operative, this diarrhea so increases in frequency and severity that it is proper to designate it the summer epidemic of the cities" (725). " Before the New York Foundling Asylum was estab- lished, the foundlings of New York, more than a thou- sand annually, were taken to the almshouse on Black- well's Island and consigned to the care of pauper women, who were mostly old, infirm and filthy in their habits and apparel. . . . "When assigned to duty in the almshouse, this service being at that time a branch of the Charity Hospital, I was informed," says Dr. Smith, "that all the foundlings died before the age of two months; only one was pointed out as a curiosity which had been an exception to the rule. The disease of which they perished was diarrhea, and this malady in the summer months was especially severe and rapidly fatal." 55. Dr. Smith says, on page 739: "Care should be taken to prevent fermentation in the food before its use, since much harm is done by the employment of milk or other food in which fermentative changes have occurred and which occur quickly in dietetic mixtures in the hot months." This, written in 1885, seems rather mild at the present time (1896) when it has become a matter of popular knowledge that such changes in nitrogenous foods render them poisonous. The "much harm is done" of 1885, should be changed in 1896 to fatal poisoning may result. SUMMER DYSPEPSIA OF YOUNG CHILDREN. 337 Every case of stale-food dyspepsia is a case of stale-food poisoning when the infected food was of the nitrogenous class. And if all ordinary illnesses from infected foods continue to be called cases of indigestion, then the more severe and dangerous illnesses from infected nitrogenous foods may in general be called cases of stale- food poisoning. That dreaded infantile illness known as cholera infantum is only stale-food poisoning, poisoning almost exclusively by badly-infected milk. And here I may quote again from Welch that "in certain cases of poisoning with milk, cheese, and ice cream, Vaughan has demonstrated a toxic ptomain which he calls tyrotoxicon." 56. Cholera infantum is the most severe form of in- fantile diarrhea. It has been so called "from the vio- lence of its symptoms, which closely resemble those of Asiatic cholera. . . . It is characterized by frequent stools, vomiting, grat elevation of temperature, and rapid and great emaciation and loss of strength. It commonly occurs under the age of two years. It some- times begins abruptly, the previous health having been good; in other cases it is preceded by the ordinary form of diarrhea" (735). A fatal termination often occurs in two or three days; and sometimes after a sickness of less than one day (735-737). Cholera infantum and ordinary summer diarrhea are continuous one with the other (739). The distinction is one of degree and not of kind. 338 STALK-FOOD DYSPEPSIA. "The duration of true cholera infantum is short. It either ends fatally, or it begins soo:i to abate and ceases, or it continues, and is not to be distinguished in its sub- sequent course from an attack of summer diarrhea be- ginning in the ordinary manner" (739). All physicians of experience agree on sending these cases to the country (741). "Many are the instances" of cases apparently hopeless going to the country and returning in the autumn in perfect health (741). 57. Although more evidence can be adduced for the same purpose, it has now, by the help of Dr. Smith's work, been clearly enough shown that the circumstances of the summer dyspepsia of young children, point much more strongly to the infected condition of the foods employed, especially the infected milk, as the cause, than to anything else probable. The foregoing discussion indicates so plainly what the means of prevention and treatment of stale-food dyspepsia must necessarily be that nothing need be added on the manner of con- ducting such cases. Stale food is the cause. All the phenomena which constitute the disease are results purely; they require no treatment, and no possible advantage is to be gained by attempting treatment of them. When the cause is removed, the disease will disappear itself, and will generally not require more than twenty- four hours to do so.
