THIS work, now offered to the public, is a Summary of the data which I have been collecting for more than a quarter of a century, with regard to the nature, causes, complications, and proper treatment of the diseases of the digestive organs ; and an experience of more than thirty years, during which time I have had the professional management of several thousands of invalids (besides hundreds which I have treated through corres- pondence), a large proportion of whom were dyspeptics, has convinced me that the theories advanced and the practice recommended in this volume, are true and successful. I have only to add, that I have not in any case administered medi- cine, but have relied exclusively on Hygienic agencies as remedial resources. R. T. T. Hygeian Home. i Florence flights, N. J.

We are a nation of dyspeptics ; and if we can believe the evidences of our senses and the testimony of physicians, we are growing worse continually. Where is this devitalizing tendency to end ? There are writers and book- makers enough on this subject, but, unfortunately, our anti-dyspeptic litera- ture, like the remedy it recommends, is more extensive than useful. Many books have been written by physicians, regular and irregular, to advocate some favorite theory or hobby, or commend some plan of medication in which the author had a professional or pecuniary interest. And a still greater number of both have flooded the country with no other motive on the part of their proprietors, than to enhance the sale of some nostrum in the shape of some " Nervous Antidote;" "Blood Food;" "Bitters;" "Tonic ;" " Hypophosphite," or Anti-disease Mixture. All of the litera- ture extant calculated to instruct the people in the proper methods for pre- venting dyspepsia, and enabling them to treat themselves when sick, with- out employing the doctor or patronizing the drug shop, is exceedingly lim- ited ; and even that little has an extremely limited demand. The public mind has been so long accustomed to rely on medicine to remove the penalties of transgression, when persistent disobedience to the laws of health has resulted in disease, that remedy and " apothecary stuff " have come to be regarded as "one and inseparable." It is a delusion, however, which has ruined more than one of the nations of the earth, and which is now insidiously but not the less surely undermining the stamina of the American people. " Every one is more or less dyspeptic now-a-days," is a common saying ; and because every one is ailing in this particular manner, it seems to be no- body's business, except *hose who make opportunity of misfortune. It should be the first business of all. It should be the first business of the 8 INTRODUCTION. Christian, the philanthropist, the statesman, the legislator, the schoolteacher and especially the physician ; for a dyspeptic race never did and never will permanently maintain any progressive government, or liberal institutions, or reformatory measures, if indeed they can do anything except relapse into barbarism or slavery, as have the nations of old. The mortality of dyspepsia makes no alarming exhibit in our "vital ( statistics." So much the worse ; for the causes of constitutional decine are overlooked. The dyspeptic person has an ever present predisposition to almost all forms of chronic disease. Indeed the dyspeptic condition is usually regarded as a mere symptom of some other malady, which receives the nosological name, and to which the death is accredited. In the mortuary statistics of the city of New York, for the last year, dys- pepsia is not mentioned as the cause of the death of a single one of the 32,647 deaths. But the fearful record appears under other names. The fact that the increased mortality of 1872 over that of 187 1 reaches the enor- mous figures of 5,500, is conclusive that something is operating among us like a continual pestilence, predisposing to a multitude of diseases, and rendering the system powerless to overcome their special causes. Dyspepsia is the condition that almost always precedes consumption ; in- deed, it may be said to constitute its strongest and most prevalent predis- position. Dyspepsia in early life, and consumption in middle life, stand to each other in the relation of cause and consequence. More than three- fourths, and probably seven-eighths, of all the consumptives in adult life, were dyspeptics in youth. It is an important fact that nearly all affections termed scrofulous and tuberculous are due essentially to that kind of Cachexia whose more prom- inent manifestations are symptoms of indigestion. Imperfect nutrition is the very essence of the long catalogue of chronic diseases which are said to consist in a " depraved habit of body," " plethora," "anaemia," scrofula, scurvy, and other morbid diatheses. The deaths in New York, in 1872, of scrofulous and tuberculous affec- tions, are put down at 6,023 ; consumption alone gives us the fearful figures of 4,274. Then there are 3,479 deaths credited to that mythical phrase, "disorders of the nervous system," nearly all of which are the sequelae of impaired digestion. We have here a record of nearly fourteen thousand deaths attributable to diseases intimately connected with indigestion, and INTRODUCTION. 9 which could never have existed, certainly not to a fatal degree, without its prior existence. But if we were to pursue the analysis through , the whole catalogue, we should be obliged to add several thousand more to our list of deaths essentially due to dyspepsia. Diseases of the liver and kidneys, gastritis, enteritis, heart-diseases, bronchitis, many cases of pneumonia, most cases of apoplexy and paralysis, and a majority of bowel complaints- cholera, diarrhoea, dysentery, colic, constipation, gall stones, intestinal concretions, worms, &c, and nine-tenths of the cases of convulsions in children, have their predisposing causes and all their dangers, aside from medical treatment, in that condition of defective or depraved nutrition to which the term indigestion is applicable, and to which it usually is applied in the generic sense. If we take New York as the basis of a calculation for our whole country, the result is frightful ; and sufficiently alarming if we discount fifty per- cent, which would render our figuring within the range of probability, if not of certainty. It would give us a national mortality of nearly one mil lion, and a mortality attributable to dyspepsia of nearly half a million. One thing is certain. The American race must arrest its dyspeptic ten- dency, or die out. The Irish, the German, and other foreign races, of nerve, stomachs and muscle, and of more ability to maintain vitality in themselves and transmit it to offspring, will ere long possess the land, un- less our devitalizing habits are reformed. Already some of our older States are in decadence in this respect, the births not equalling the deaths. And the general repugnance of American wives to become mothers is more attributable to the general dyspeptic condition which unfits them to b* mothers, and renders maternity painful and perilous, than to all other causes combined. Arbor Vit^. PART I. DIGESTION*. CH APTER I. NUTRITION. Nutrition is tne aggregate of all the organic processes. It may be distinguishable into digestion and assimilation. Dis- integration is the separation and expulsion of the debris, or waste matters of the structures. Digestion, in the proper sense of the word, means the preparation of the food for assimilation. It comprehends insalivation, solution, chymification, chylifi- cation, and aeration. A brief exposition of the Physiology of Nutrition, in the order of the digestive processes, will the better enable us to understand the disorder of the same processes, which constitutes indigestion or dyspepsia. And to make the subject more intelligible to the non-professional reader, let us take an article of food, an apple, if you please, and trace it through all of its changes from the tree which produces it, to the tissue which assimilates it. But, in order to understand the illustrations, the reader must steadily keep in mind a few propositions which are fun- damental, and which, except the last three, are in direct an- tagonism with the doctrines taught in the text-books of our medical colleges. These are : i. All the actions and changes of living organisms are vital, not chemical. There is no chemistry in living structure. Hence all attempts to explain the problems of life by chemical data must forever be fallacious. II T2 DIGESTION. 2. In the relations between dead and living matter, the liv- ing acts on the dead. Hence medicines do not act on the living organs or structure in virtue of inherent or elective affin- ities, as is taught in the works on Materia Medica and Thera- peutics, but, on the contrary, are resisted and rejected by the living organs and structures. Nor do poisons act on the living system, as is taught in the works on Toxicology and Medical Jurisprudence, but contrariwise, the living system acts in relation to them. 3. Diseases are not entities, nor processes necessarily inim- ical to vitality, nor materials nor forces at war with the vis medicatrix naturce, as taught in the works on Pathology, but, on the contrary, all diseases are remedial efforts, whose object is the defence and purification of the vital organism, and the repara- tion of the deranged structures. 4. Food, drink, air, and other " Hygienic agencies," are in no sense " stimulants," as taught in the standard works on Dietetics ; nor do they in any sense act on or do anything to the living organs, as taught by the chemico-physiologists * but, on the contrary, they are acted on by living structures. 5. Neither medicines nor foods possess any ' ' properties " which they impart to the living structures, as is taught in all of our medical schools, with a single exception ; but on the con- trary, they possess inorganic elements and organic compounds which are rejected or appropriated by living structures. 6. Poisons are those agents which are rejected from the vital domain (emetics, cathartics, tonics, stimulants, narcotics, etc.), and foods are those substances which are usable in the forma- tion of the bodily structures. 7. The vegetable kingdom feeds only on inorganic or cnem- ical elements in a state of solution, transforming them into organic products, or proximate elements, which proximate elements, as combined in the processes of vegetable growth, constitute food for animals and man. 8. Animals and men cannot feed on inorganic or chemical elements, these invariably being to them in the relation of poi; INSALIVATION. «3 sons, nor can any organism, except that of the vegetable, produce food of any kind. Hence animals that eat other animals can only get such aliment as they have received from the vegetable kingdom. CHAPTER II. INSALIVATION. The first act of digestion, after prehension, or taking the food into the mouth, is mastication. The object of mastication is insalivation. Every particle of food should be mingled with saliva, or digestion cannot be properly performed. And here, in the outset, we see one of the most prolific sources of disease in i 1 high civilization" — imperfect mastication. As meals are presented at ordinary tables, and in all hotels and boarding- houses (except a few of those which are called Hygienic), very few dishes are in a condition to secure mastication, or that even admit of chewing ; while the few which might be masti- cated more or less, are hurried into the stomach, or washed down with milk, tea, coffee, water, or some kind of alcohol- ized or otherwise medicated fluid. Those who would have perfect digestion should not drink anything at meals. Drink- ing should always be done before, after, or between meals. Many physicians, and some Hygienists of loud pretensions, are very fond of milk themselves, and very fond of recommend- ing it as a leading article of food for all enfeebled conditions of the digestive organs — dyspepsia, liver complaints, nervous debil- ity, consumption, etc. — and even in fevers. And some of them seem to be ' ' obsessed " with the chemico-physiological phantasy that milk, like fish, is a peculiarly phosphorizing ali- ment, *nd hence marvellously conducive to brain-tissue and mental power. Btif such advice is always bad. Many patients can survive it, and many will improve in spite of it, provided the sum total of all their other habits have been changed for the beuer DIGESTION. Milk cannot be among the better articles of the dietary for adults in any case. Why ? They do not masticate it. It is true that milk, when pure and normally produced (I do not mean the commercial article), contains all the nutrient elements that the various structures require ; but, unless insa- livated, it cannot be properly elaborated and assimilated. How well it can be used depends, of course, on the more or less healthy condition of the digestive organs. With some it seems to agree very well ; and the same may be said of much worse things. With others it disagrees very decidedly, and in all bad cases of dyspepsia, consumption, or biliousness, it in- variably aggravates. It is also especially pernicious in all of those complicated and obscure cases of indigestion to which the phrase, nervous debility, is usually applied, as I have demonstrated in many hundreds of cases. It is said in reply to these objections to milk as an article of diet for persons after the period of infancy, that nursing children, and the young of all mammalia thrive on it, that they eat almost nothing else until near the " weaning-time. " Ad- mitted. But infants take it "the natural way." They masti- cate it. They eat it. They do not drink it. They take it drop by drop and insalivate it particle by particle, as it flows from the mothers breast, or from the nursing bottle when this is properly adjusted. If the milk is swallowed too fast, as will be the case if the mother uses too much slop-food, or drinks largely of tea or coffee at her meals, or if the nursing bottle has too copious a delivery, or if rapidly fed with a spoon, the child will throw it up ; and if this habit is long persisted in, the milk will ferment more or less, the child have a sour stomach, flatulence, acrid eructations, canker in the mouth, etc. In a word, "the dear little fellow" will be a miserable little dyspep- tic. The same things will occur if the child inherits, because of the erroneous dietetic habits of one or both parents, a debili- tated or imperfect condition of the digestive organs, rendering the secretion of the saliva and gastric juice deficient in quantity or depraved in quality. Obstinate constipation, chronic diar- rhoea, erysipelatous eruptions, bilious humors, scalled head, etc., INSALIVATION. 15 are among the affections which are frequently congenital and con- stitutional, because of the dietetic errors of those whose sacred duty it was to transmit to them a sound organization — or none. I would have no objection to pure milk as an article of food for adults, provided they masticate it. But this is never done. The adult always drinks it, and never eats it. If he takes it with solid food, bread and milk, for example, the fluid or milk is swallowed (drunk) before the bread is masticated (eaten), or the whole is bolted down unmasticated together. It would be impossible, or at the least very awkward for ' ' children of a larger growth, " to take milk as infants do. What young lady or gentleman would not regard it as a huge joke, or a down- right insult to be presented, at a restaurant, with a glass of milk and a straw or glass tube through which to suck it, as though it were a i ' brandy smasher, " or a rumified glass of soda water ? Nearly all adults who use milk at meals, sip or drink it as they do water or other liquids. The practical rule deducible from these considerations is, that all kinds of food which are only semi-solid, or composed of solid particles diffused in water, as puddings, stews, mushes, gruels, soups, etc., should always be taken with dry bread, hard cracker, green apples, or something similar, and eaten very slowly. The common practice is the reverse ; the more fluid dishes are spooned down as rapidly as the process of de- glutition can be performed, and the solid material, more or less masticated, hurried after it. The disease termed Mumps (Parotitis) is an inflammation of the parotid glands ; and when both are affected at the same time, the mouth is very dry ; mastication cannot be performed without pain, nor can the " sensible properties " of food be recognized as in the normal state. If strong acids are then taken into the mouth, as vinegar, a peculiar benumbing sen- sation is experienced. Those who use tobacco, alcohol, or condiments excessively, have a condition of the salivary glands not unlike chronic parotitis. We will the better appreciate the importance of the insali- i6 DIGESTION. vation of our food if we notice the ample provision that nature has made to ensure it Fig. i. In Fig. i. all of the salivary glands are represented in their natural situation. 1. The Parotid gland, extending from the zygomatic arch of the cheek-bone to the angle of the jaw below. 2. Its duct, termed the duct of Steno. 3. The Sub-maxillary gland. 4. Its duct. 5. Sub-Lingual gland. There are no less than six glands appropriated to the work of secreting from the blood the indispensable digestive fluid termed saliva ; two parotids, situated one on each side of the head, above the articulation of the lower jaw and near the phrenological organ of alimentiveness ; two sublinguals under the tongue, and two submaxillary, between the others. One of each of these glands is represented in the illustration, Fig. i. \ The location of the salivary glands shows their intimate relation to mastication, as well as to the perception or recog- nition of alimentary substances. The proximity of the two large parotid glands to the organs of alimentiveness explains why the ' ' mouth waters " instantly when a luscious peach, or a basket of ripe strawberries (with or without the cream) comes within the range of vision ; and the near proximity of the other salivary glands to the tip of the tongue, explains why savory substances in contact with that organ, so readily excite a flow of saliva. Again, they are all so distributed as to be INSALIVATION. excited to action by all the motions of the tongue and jaws, when in the act of mastication. That the salivary secretion is sufficient for moistening all food that it is proper to swallow, is proved by the fact that no true Hygienist ever experiences any thirst while eating ; and no one who has a normal secretion of saliva, and who tho- roughly masticates his food, will ever desire to drink at meals, provided the food is of proper material, properly cooked, and not improperly seasoned. It is true, however, that high seasoning of all kinds, all indigestible admixtures, and all thirst-provoking condiments, necessitate a corresponding degree of water-drinking while eating. But this is only on the prin- ciple of the lesser of two evils. Fig. 2. The provision for moistening and insalivating the milk on which chil- dren may properly subsist, is well shown in Fig. 2, which is a repre- sentative of a single lobule of the parotid gland of an infant, inject- ed with mercury, and magnified fifty diameters. Lobule of Parotid Gland. One of the great and increasing evils of imperfect mastication is decaying teeth. It is a law of all vital organisms that every structure or part must do its own work or die. If a hand or an arm was not exercised it would soon perish. Every organ and structure pertaining to individual life, that is not duly ex- ercised, will be correspondingly enfeebled. Do we not have a sufficient, as well as a sad illustration of this subject in the tens of thousands of dentists ; in several dental colleges, and in the immense establishment in Philadelphia for the manufacture of artificial teeth, to say nothing of the instruments for pulling the rotting teeth out, which are a part of every country physician's outfit ? In a majority of cases, the teeth of our fast-living Americans begin to decay in childhood. A young lady or gentleman with a sound set of teeth is an exception to the general rule. In i-8 DIGESTION. thousands of instances the young man or young woman needs a set of artificial teeth before he or she is ready for the mar- riage relation. And if both parents are teethless in early life, the prospectus dentatus is bad for the rising generation. If the teeth were properly treated they would never decay. There is no more reason, except abuse, why the teeth should ulcerate or become loose, than there is for the fingers or toes, or the ears or nose, to rot and fall ofT. The teeth are the densest, firmest of all organic structures, and should be the very last, instead of the first, to decay. Domestic animals that are permitted to live normally never have decaying teeth. No matter to what age the animal lives, its teeth will be found perfect in the skeleton. And such would be the case with every human being if the teeth were not abused by non-use. It ought to be known to all, as it is known to those who have lost their teeth, or a part of them, that a whole set of sound teeth is as essential to comfort as it is to health. Nothing but thorough mastication, and complete insalivation can enable one fully to realize the properties of food. All proper food is pleasant to the unperverted taste, and the palate relishes it with a zest proportioned to its own integrity, and the fineness to which chewing reduces it into molecular particles. Those whose teeth are too tender to masticate solid food well, or have not teeth enough remaining to do it, have little idea of the taste of an apple, a potato, or even a piece of bread, made of nothing but wheat-meal and water. They require salt, vinegar, pep- per, sugar, butter, or something else, to make their victuals " taste good." But no amount of salines, acids, or pungents can render it so delicious and satisfactory as natural appetite and proper mastication ; nor is there any remedy for decaying teeth, rotting jaws, bleeding gums, and tartareous excrescences, except exercising the teeth in mastication. This whole subject is so well explained and illustrated in the Science of Health for August, 1872, that, with the permission of the publisher, I transcribe the entire article THE TEETH. CHAPTER III.- — THE TEETH THEIR USE AND CARE. Persons who have any pretensions to culture and refinement, regard the teeth as ornamental, as well as useful. Before Fig. 3. — Complete Set of Permanent Teeth, Showing the Nervous Connections. In this illustration the bony matter has been carefully cut away to show the roots of the teeth and the nerves which connect them with the brain. the age of dentistry, the loss of a tooth by decay was a life-long misfortune. Now,, if one or more of the teeth decay or by accident are broken and lost, skilful dentistry supplies by arti- ficial means those which match the original, and the mouth is kept shapely and beautiful. Within the last thirty years, the science and art of dentistry has made very great progress. Not only can the teeth be treated in such a way as generally to preserve them, but when they commence to decay, the cavities can be so prepared and filled that they last or promise to last a lifetime ; whereas, half a century ago, decay once commencing would go on, causing intense suffering to the patient and an early loss of the tooth. We often regret to see persons with excellent sets of teeth permit them to remain without being cleaned, the particles of 20 DIGESTION. food being allowed to lodge between them and decay, creating corrosive acid, which destroys the enamel, besides greatly de- praving the odor of the mouth. Every person, after eating, should carefully clean the teeth , from all particles of food with a quill or wood pick, and then, Fig. 4. — Diseased Teeth. Fig. 4 — Represents the jaws, with several of the teeth in a diseased state. Some portions of the bony matter have been removed in order to exhibit the parts affected. All the teeth which are numbered, except No. 3, which is entirely sound, are carious, the disease having penetrated to the nerve. Nos. 1, 4 and 7 show the jaw and teeth in an early stage of disease.

In this way many a set of teeth could be kept sound and hand- some through life, which by being neglected become diseased and decay early. Some people pick the teeth with a penknife or with a pin, which we think an erroneous practice. The use of hot drinks, and on the contrary, ice-water in hot weather, tends to the decay of the teeth, because it produces a fever, and sudden changes in the system, which seriously affect them. Disease of the teeth appears in several forms. One is by caries or decay from the surface. Another is by ulceration at the root, and a third is by tartar, which displaces the gum and leads to the decay or absorption of the bony matter constituting the sockets of the teeth, called alveolar process. The remedy for tartar is to have a skilful dentist remove it as soon as it is observed. Indeed an examination should be made by him occasionally to detect its presence. Proper care of the teeth by the use of a brush after every meal would generally prevent all accumulation of tartar. These conditions we illustrate by means of several en- gravings. The Indians are proverbial for their good teeth. We have examined many Indian skulls and have frequently found the teeth worn down to the gums with not a speck or decayed spot to be found on them. Besides, we do not find on Indian teeth tartar, or salivary calculus, as is too often the case with civilized men's. There may be many reasons why the teeth of ) Indians are in better condition than the white mans. The chief one perhaps is, that they give their teeth ample exercise. If a cow is fed on food that requires no mastication, her teeth become decayed. If she crops the grass with her incisors, and grinds it with the molars, they will last her life-time in good condition; but let her be put into a stable and fed on still-slops, and the teeth at once begin to decay, as also the bony structure in which they stand. The Indian eats parched corn. Having no grist mill, he grinds his food with his teeth, and the result 22 DIGESTION. is, every tooth is exercised. If we eat porridge, broth, stews, and everything else cooked softly, and get no exercise for the teeth, they become to us almost useless ; the gums become unhealthy, the teeth decay, and give us a world of trouble. Moreover the Indian sleeps with his mouth shut, breathes through his nostrils, and does not draw the cold air rapidly over his teeth. This is true of all animals. The canine and feline tribes, that pant when they exercise violently, open their mouths and breathe through the mouth ; but they sleep with their mouths shut. White men sometimes breathe the live- long night chiefly through the mouth. The celebrated Mr. Catlin, who writes on Indian habits, attributes bad teeth to the white man, in consequences of sleeping with his mouth open. Fig. 5.— Complete Set of Infant Teeth at Four Years. Always beware of using scouring material on the teeth. A little fine soap on the tooth brush, to make a pleasant lather in the mouth, is believed to be favorable to the health of both mouth and teeth. One half of the tooth-powder have acids in them which injures the enamel of the teeth. Any gritty sub- stance which tends to wear off the enamel is bad. In cities, quack peddlers of tooth-powders may be found at INSALIVATION. 23 the corners of the streets. They will get some dirty boy's mouth open and with strong acid make his teeth shine like ivory. This they do as an advertisement. We never fail on seeing a crowd of ignoramuses gathered around such a quack to speak frankly to them, and advise them to avoid it alto- gether. One of these men once overheard our remark, and said "What is it to you?" Our reply was, "We wouldn't put such acid on our teeth for five hundred dollars." His crowd of customers vanished. Fig. 6. — Teeth of a Cow Fed on Natural Food. Having exhibited the anatomical situation of a complete set of permanent teeth, showing their nervous connections, and also a permanent set of teeth in a condition of disease in various stages, we come now to consider infantile teeth, and introduce an engraving for that purpose. The bony structure is cut away on the jaws to show the roots of the milk teeth, as they are called, and also to show the ultimate teeth or the permanent set behind the milk teeth. Before birth the teeth are organized rudimentally, two sets of them, one above the other ; and at birth, existing in the jaw entirely below its service, there is a set of teeth, and under this set there is a little sack, which is to be, when developed, a permanent tooth. In the engraving one half of twenty teeth are represented. 24 DIGESTION. In the adult mouth there are thirty-two teeth. In the rear of the mouth of this engraving there will be seen the rudiments of the permanent teeth, over which no milk teeth are developed. In the child's mouth then there are twenty teeth, and in the adult mouth thirty-two, including the wisdom teeth, which come late, at from twenty to fifty years of age. Fig. 7.— Jaw of a Cow Fed on Hot Still-Slops. The infantile teeth are small, being adapted to the size of the jaw. When the child's age advances these teeth separate, the jaw grows and the teeth are rendered further apart. If the teeth are not extracted soon enough, the permanent teeth sometimes push out at the side. This often happens in the case of the eye-tooth ; but generally the teeth are lost one after another, first on the lower jaw ; the jaw expands and the cavity of the mouth increases so as to make sufficient room for the large permanent teeth. The process of cutting teeth is not an unnatural one, and ought not to be painful or dangerous. In the present state of things, however, children often suffer severely from it, and not unfrequently life is destroyed in this way. This, of course, is induced by irritation and feverish excitement, which is con- nected with the brain by means of the nerves of the teeth; the same amount of pain might be sustained by the patient without injury, if related to the foot or hand and farther away from the brain. The bad habit of feeding children cake, sugar and candy, INSALIVATION. 25 Fig. 8.— Tartar on Foul Teeth Tartar Removed is often the cause which tends to produce much trouble relative to the teeth, especially early decay, which is at present so com- mon. Our artificial modes of living greatly destroy the natural order of development in children, hence it is supposed that the trouble with the teeth is the result of ages of wrong courses of living. The death of one half of all the children that are born before they come to maturity is a sad commentary on the crea- tive wisdom that established the natural laws and punishes the bad habits and usages of civilized society. Nature is per- fect. God the Creator is all-wise and beneficent. If we were but wise enough and good enough to obey the laws of o*ur being, this great mortality of children, this falling off of human fruit before it is ripe, would be done away with. Mr. Catlin asserts that nearly all the infants among the Indians, unless they died of accident, came to maturity. Though he saw as many as four thousand Indian skulls in a depository of the dead, there was not an infant's skull among them. The death of infants and children was so rare, that the oldest inhabitants had to study to recall the death of children, except of accident. But our children inherit, with the abuses of civilization, bad conditions of the teeth generally from parents who have lived in an abnormal way ; hence the great trouble with cutting the teeth, and with their early decay after they are cut. A full set of false teeth, in the upper jaw at least, is very com- mon among women of twenty-five and among men of thirty- five in our own country to-day. Occasionally we find one of the old stock who retains a healthy and vigorous set of teeth until he is seventy years old. without a speck of decay, with the ranks all full. This law of temperance and health, 0? 26 DIGESTION. sound constitution and sound teeth with long life, pertains to •he animal kingdom as well as to men. The cow's jaw, (Fig. 6,) shows every tooth in its place and jrder, with a fine enamel, adapted to do the work for which they are designed ; and when these teeth are used in the natu- ral way they are healthy, and we may safely conclude the ani- mal is throughout in like healthy condition. But when we turn to the under jaw of the cow that has been fed on warm still-slops and kept housed up — even as women and children often are- — secluded from wholesome air, we find the teeth de- cayed and the bone of the jaw unhealthy, and we have a right to infer that the whole animal is in a similar unhealthy condi- tion. The illustrations of tartar which we present, show a very common neglect in taking care of the teeth, and though the teeth themselves may not be decayed, the bony socket which contains them decays, and sometimes the teeth, lacking sup- port, fall out and are lost. One of the best evidences of good culture and proper care of one's self, is a tidy mouth and nicely kept teeth. Every reader knows some person who, when he laughs, presents teeth that are covered with tartar, or blackened by smoking, and whose mouth is a disgust to every beholder. Such people should go to a mirror, where they can take a view of their open sepulchre, full of dead or unclean bones. fhe lowest forms of animal life have the simplest digestive fct *aratus, and subsist on such kinds of food as require little elaboration. The very lowest animals that we can trace seem to be all stomach, all the processes of digestion being performed In a single canal or cavity. No animal ever manifests two v fgans or structures, or parts, without one of them being ana- logous to a stomach. The monera, the lowest form of animal life yet recognized, has, apparently, no organs, parts nor struc- tures. When it needs food it projects an instrument and takes it into its substance. Yet it has a digestive apparatus, or it would not live, develop, grow, nor divide into parts, nor differ- INSALIVATION. 27 ential into organs. The digestive organs of fishes and reptiles are comparatively simple. Birds macerate the grains and seeds in their crops, and then masticate them in the stomach. The gizzard, a tough muscular substance, lined with an exceedingly dense membrane, capable of grinding stones, metals, and even glass to impalpable powder, performs the office of teeth. In the carnivorous quadrupeds the stomach is much smaller and the alimentary canal much shorter than in the herbivorous, while the omnivora have an intermediate size of stomach and length of intestines. The lower jaw of the carnivora has only the up-and-down, or cutting motion, while the teeth are adapted to tearing the flesh on which they subsist, as seen in the cut, Fig. 9. Fig. 9. In the omni- vora, of which the hog is un- fortunately our most familiar example, the back teeth have a close resem- blance to those JAWS AND TEETH OF A PANTHER. of herbivorous animals, while the front teeth exactly re- semble the tearing and dagger-like teeth of the carnivora, as represented in the cut, Fig. 10. Fig. 10. UNDER JAW AND TEETH OF THE HOG. 28 DIGESTION. The masticating organs of the camel, which subsists on the coarsest herbage, show a much stronger resemblance to those of carnivorous animals than do those of the human being ; and hence, if we are to judge the natural dietetic character of man from the standpoint of comparative anatomy alone, we must place him at a farther remove from flesh-eaters than is the camel. It can hardly fail to be noticed by the attentive reader that the irregular arrangement of the teeth peculiarly fit the animal for munching and breaking up the branches, sprouts, stalks, etc. , which constitute a large proportion of its food. Fig. ii. JAW AND TEETH OF THE CAMEL. The articulation of the lower jaw also admits of the lateral, rotary, and grinding motions, as with all grass-eating, grain- eating, and fruit-eating animals. Fig. 12. In the jaw of the horse, Fig. 12, the in- cisors, or cutting-teeth, are placed in front, to enable it conveniently to crop the grass and other herbage ; and the grinding-teeth, for mashing and comminuting the food> occupy the back part. There is no trace whatever of tearing, or carnivorous teeth. In the orang-outang, Fig. 13, which is a purely frugivorous animal, the articula- tion of the jaws admits of the grinding motion. In some of the monkey tribes, the baboon for example, the cuspids do resemble the corresponding teeth of the carnivora ; they are not, however, used for flesh-eating, but SKULL OF THE HORSE. INSALIVATION. 2 9 seem to be an arrangement which serves them for weapons of offence or defence. The distinctions of the human teeth are seen in the illustra- tion, Fig. 14. The incisors (I) are intended for biting and cutting the fruits, nuts, grains, or whatever may be his proper food ; the cuspid or corner-tooth (C), sometimes called canine Fig. 13.

The following communication to the Science of Health, by Mrs. Fannie R. Fendye of Baltimore, Md., may fittingly con- clude this branch of our subject, premising, however, that it is not 1 ' betel-eating " but better mastication and fewer unhygi- 30 DIGESTION. Fig. 14.

THE TEETH AMONG DIFFERENT NATIONS. " In all the cities of south-eastern Asia I found not a single dentist, with the solitary exception of one in Calcutta. And even he, I think, has since retired for want of employment, and gone home in disgust — resolved, henceforth, to live among people sufficiently 1 civilized ' to destroy their own teeth and wear artificial ones instead. This paucity of supply must indi- cate a want of demand ; as it is unquestionably true that the ranks of the dental profession are ever increasing — the colleges of our own country alone sending out regularly graduates enough, it is said, to supply the world. In India there are merchants, lawyers, clergymen, physicians, druggists, soldiers, sailors, teachers, and mechanics, both native and foreign. Only dentists are lacking, and the reason is because they are not needed. ' ' Everybody has fine teeth in the East. I have seen both men and women, at ninety, with perfect teeth, and seldom ono INSALIVATION. 31 under fifty who had lost a single incisor or cuspid, and perhaps not even a molar. " Two European gentlemen, aged respectively twenty-six and thirty, were one day conversing with a young Siamese noble, who remarked that he could never guess the age of foreigners, as they looked so different from natives. The younger of the two then said, 'What do you imagine my age to be?' ' About nineteen or twenty, I suppose, ' was the reply. 'But really, I think you look even younger/ 'Well, but see here, ' said the foreigner ; 1 1 have lost a tooth, ' pointing far back in his mouth to the place from which one of his ' wis- dom-teeth ' had recently been extracted. ' Have you, indeed?' asked the noble, manifesting great concern — 'then you must be eighty or ninety. I did not think you were so old.' "The late kingofSiam, who died at the age of sixty-five, had a set of teeth that our proudest belle would have gloried in — except the color, for he always had them painted black — the Siamese, in common with most oriental nations, deeming white teeth a vulgarity. Paint for the teeth is in the East as in- dispensable an article of the toilet, as powder and rouge for that of a French woman. Even young ladies with pearly teeth so exquisitely beautiful that it would seem sacrilege to mar their gleaming whiteness, will, as soon as they become of age, — that is, ten years old, after which they are considered marriage- able — commence staining the teeth, first red, and afterwards jet black, and so they are worn through life. But this is by no means to avoid the trouble of keeping the teeth in neat condi- tion ; for, as a general rule, orientals take far more care of the teeth than do most western nations. "Toothache is, I think, utterly unknown in the East, except among white foreigners, as I do not remember to have found a single case among the natives. Certainly there must be some cause for this marked exemption from diseases of the teeth. It may be due, in part, to the constant use of the betel or artca-nut, which all classes and both sexes, in nearly every part of India, chew all day long. They combine with the betel, chunam, 32 DIGESTION. pepper-leaves, and fine-cut tobacco — little trays containing these various ingredients of the popular quid, standing about in every apartment, ready to be offered to honored or welcome guests, the moment they are seated. Not to offer it, is deemed a lack of hospitality, or an intimation that the visitor is not received as an equal or friend. Eating betel is in Southern and Eastern Asia, just what eating salt is in Western Asiatic countries — a token and bond of perpetual friendship, that not even a rogue or a murderer would violate. Those who have once partaken together of the ' betel quid, ' are thenceforth sworn friends, till death sunders the compact. The arica is highly astringent, like the nut-gall ; and from this quality may tend, in some mea- sure, to the preservation of the teeth. Another cause is, probably, found in the extremely regular habits of all classes in regard to meals, with which nothing is allowed to interfere. When dinner-time comes, an oriental dines > whether he is at leisure or not ; and he would do so, I think, if a beleaguering foe were thundering at his gates. But between meals they never eat. Such habits in regard to eating, cannot fail to be pro- motive of the general health, and, of course, the teeth share the benefit. A still more potent cause is, I think, the fact that orientals never take either food or drink, very hot or very cold. Ice is unknown in most parts of the East, and none but for- eigners, or those who have learned it from them, make any attempt to find a substitute for ice, by artificial cooling pro- cesses. Tea and fruit juices are the beverages most in favor ; the former taken without cream or sugar, and only moderately warm ; while the latter are used just as they are expressed from the fresh, ripe fruit. How absolutely opposite to the habits of nearly every American, at home or abroad ! It is said by those who have taken pains to inform themselves on the subject, that there is no country in the world, civilized or savage, where bad teeth are so generally the rule, and good ones so rare an excep- tion, as the United States. And there is probably no other nation who so generally swallow tea and coffee hot enough to scald the throat, and then 'cool off' by an immediate draught of iced-water. An Englishman would regard such a habit as THE TEETH. 33 absolutely suicidal, and he is amazed that sensible Americans so recklessly jeopardize health and life. At English hotels i people can, of course, have whatever they demand and pay for, as at public houses elsewhere ; but in private families in England, even the wealthy, the use of ice is only moderate and occasional — not by any means the constant, every-day, excessive affair it is with us ; and there it is never taken immediately after hot drinks, as at breakfast and supper among Americans. Neither do English people eat irregularly, and at all hours between meals, as do many of our countrymen — a practice by which the diges- tive organs must become impaired and the general health suffer, even if the teeth did not. " Another deleterious practice, common in our large cities especially, is the excessive use of ice-cream and soda-water. Nothing is more common on summer evenings, than for young people to swallow, at their boarding-houses, a cup or two of coffee boiling hot, and as rapidly as if they were drinking for a wager, and then to rush out for an ice-cream or glass of soda, "to cool off with" — the "fruit syrups" of the soda water often containing ' ' fusil oil " and other poisons, apart from the delete- rious effects on the teeth of these extremes of heat and cold following each other in quick succession. A distinguished dentist told me recently, that it was difficult to conceive of any- thing wore absolutely destructive to the teeth than the simultaneous use of cold and hot drinks. And he added that he had known scores of Europeans, who came to the United States with teeth, that, with the habits of living to which they had been accus- tomed at home, would probably have lasted to extreme old age — glad, in less than five years after they came amongst us, to avail themselves of the services of a dentist to manufacture an artificial 'set/ ' ' Surely something may be done, to avert this wide-spread curse of toothache and discolored, uncomely teeth, or the only alternative that remains of wearing those not ' to the manor born so that Americans of future generations, at least, may cease to enjoy the enviable distinction of belonging to a toothless nation.

The Roof of the Mouth, bounded by the Superior Dental Arch. After the food has been properly masticated, it is to be swal- lowed. The next process, therefore, is deglutition. And it is worth a moment's delay to consider the ample, if not wonderful contrivances for effecting the passage of the food from the mouth to the stomach, without the artificial aid of drink. On each side of the mouth, at the commencement of the Pharynx (back part of the mouth), is a glandular organ, termed Tonsil, whose office is to furnish a lubricating fluid. This is shown in the cut, Fig. 15, 8. In addition to these glands, the whole mucous surface exhales a moistening and lubricating fluid, more refined than any oleaginous matter ever produced by artificial means, that used in sewing machines not excepted. This secretion is formed in tubes, called Mucous Follicles, the orifices of some of which are shown at 7. Persons who use very hot drinks, and irritating condiments, or strong alkalies, \ sometimes have a thickening of the mucous membrane of the oesophagus, which renders deglutition difficult. II CHYMIFICATION. 35 CHAPTER V. CHYMIEICATIOBT. The second stage of digestion, in the processes of the trans- formation of the food elements into living structure, is termed chymification. This is performed in the stomach. The older physiologists regarded digestion in the stomach as analogous to fermentation ; modern authors are very discordant in their opinions of the nature of the process, some regarding it as mainly mechanical, and others as purely chemical. The sim- ple truth is, it is a vital process, as are all other processes per- taining to living organisms. In the stomach the food is mingled with a solvent, called the gastric juice, whose wonderful properties have thus far eluded all chemical and microscopical investigations. It is known to be slightly acid, and to have a power of transforming organic ele- ments unlike that of any other known substance. It is said, also, to "digest" inorganic, and even metallic substances, which have been purposely or accidentally swallowed ; but this opinion is certainly an error, for oxidation, or decomposition, tvhich is all that can happen to them in the gastric cavity, is a rery different process from digestion. A general view of the abdominal organs is represented in Fig. 1 6. The adipose matter in the chest has been removed, as has the Greater Omentum, which covers the viscera in front. The liver also has been turned back to exhibit its under surface and the Lesser Omentum, It will be noticed that the stomach is nearly semicircular in shape, concave above and toward the liver on the right side, convex toward the spleen on the left side, and that its main bulk is on the left of the median line. The stomach, heart, and spleen are all chiefly on the left side, a provision which seems necessary to counterbalance the largest glandular organ of the body, the liver, which is situated on the right side. A knowledge of this arrangement of the organs enables us to un- derstand many of the complicated and obscure pathological 36 DIGESTION. Fig. 16. i. The gread Blood-vessels. 2.

When congested, its very weight causes a painful, drag- ging sensation in the vicinity of the stomach, and when very much enlarged it causes the body to bend to one side, especially in young persons, often resulting in double curvature of the CHYMIFICATION. 37 spine. I have known several children who were badly incur- vated, attended in some instances with partial or complete paralysis of one of the lower extremities. And I have known such patients treated for months with tonics, showering, elec- tricity, " movements," and some worse things, without benefit, and without any suspicion on the part of the attending physicians of the real nature of the difficulty. In other cases its pres- sure against the stomach would cause much distress in that organ, especially after meals. In still other cases its upward pressure against the diaphragm would cause continual diffi- culty of breathing, occasioning short breath, coughing, and palpitation, whenever the patient would step hurriedly, or walk up-stairs, often resulting in severe asthmatic paroxysms. These patients can never be cured, as the reader will readily understand, until the diseased condition of the liver is pro- perly attended to. The relation of the stomach to the great blood-vessels below the heart, enables us to explain many strange and often frightful sensations with which all dyspeptics are more or less familiar. The illustration, Fig. i 7, represents the stomach and oesopha- gus in their natural position, and shows the proximity of the stomach to the descending aorta and other large blood vessels of the abdominal cavity. The thoracic viscera, nearly all of the diaphragm, and the intestines, have been removed ; the peri- toneum (lining membrane of the cavity of the abdomen) has been detached from the kidneys, and the duodenum is left. One of the most distressing symptoms of many dyspeptics is a hard beating or throbbing behind the stomach. It is gene- rally worse soon after lying down, and the throbbing is some- times so violent as to jar the whole body and shake the bed- stead. Many persons in this condition have apprehended "organic disease of the heart," and not unfrequently their physicians, unable to account for these occasional tumults of the central organ of the circulation on any other hypothesis, have diagnosticated 4 'heart disease." A reference to the illustration will make the matter plain enough. All dyspeptics have one of four conditions, and 33 DIGESTION. Fig. 17. ~ Stomach and Great Blood-vessbls. 1.

A contracted and rigid state of the abdominal mus- cles. 4. Congestion of the ad- jacent organs — lungs, spleen, Sidneys and pancreas. Either condition causes obstruction to the free passage of the current of blood down the descending aorta, and when all co-operate, the effect is extreme. The swol- len organs and unyielding muscles press the stomach directly against the large blood-vessel, so that every contraction of the 1 left ventricle of the heart propels a column of blood through the arteries on which the stomach presses, not only causing the jarring or throbbing sensation, but actually lifting the lower side of the stomach to some extent. The effect is exactly analogous to that of moderate blows or rappings against the under side of the stomach. If the region around the stomach is contracted, as is the case with many " confirmed dyspeptics/' or "caved in," as is the case with all women who have laced tightly in early life, this pounding symptom is greatly aggravated. In such cases the patient, on retiring to rest and assuming the C H YMIFIC ATION. 39 horizontal position, will often experience noises in the ears like the "sound of many waters/' or the rushing of a cataract. This symptom is also always worse soon after taking a full meal , and if such a person take a "hearty supper," and retire immediately to bed, his sensations will be more forcible than agreeable ; and his unquiet slumbers will alternate with parox- ysms of incubus, preceded by frightful spectres, fantastic situa- tions, impossible adventures, and all the goblins of air, earth, and sea.

For this purpose it is mixed with the gastric juice and compressed and kneaded by the muscles which constitute the middle coat of the stomach. The fibres of this muscular coat are so arranged as to do their work admirably, as is shown in the illustration, Fig. 18, which represents a front view of the stomach, distended with air, the peritoneal coat being turned back. It will readily be seen that this arrangement of longitudinal, circular and oblique muscular fibres allows the stomach to 40 DIGESTION. compress and knead the ingesta in all possible directions, as the varied motions of the tongue enable it to move the food in the mouth, during mastication, in every direction. The active principle, or solvent, of the gastric juice, is evi- dently corpuscular, as is, probably, that of all organic secretions. A something analogous to this has been obtained from the analysis of the gastric juice, and termed pepine ; but pepine in the living organism, just as nature produces it, and pepine out of the living organism, as the chemist prepares it, are very different materials, although the latter does produce a solvent effect on alimentary substances. But the idea of introducing pepine into the materia medica as a substitute for the gastric juice, or as a remedy for indigestion, is as absurd as would be the notion of preparing our food in such a manner as not to require mastication. Indeed, this latter practice is very general, for, do not learned physicians tell us, and eminent physiologists explain to us, that bread, for example, when made light by fermentation, can be more readily permeated by the saliva and gastric juice ? Surely they forget, when treating of dietetics, the nature of the physiological function termed mastication. The pepine which is employed as a "digester" in medicine, is usually obtained from the stomachs of pigs, by scraping the mucous membrane with a blunt instrument. In order to pro- duce it in large quantities the animals are kept without food until their appetites become keen, and then placed where they can smell the food without getting hold of it. The smell of the savory viands provokes a flow of gastric juice, or of some- thing analogous, which is then obtained pure, as is supposed, by killing the animal. But, as all organic secretions are modi- fied by and partake of the dietetic character of the animal, it seems to me that the omnivorous swine, always filthy and scrofulous in its domesticated condition, is the worst possible source from which to obtain pepine for the human stomach. The peptic corpuscles of a scrofulous pig may infect the human being with malignant disease, as readily as the vaccine virus from a diseased animal produces the worst forms of confluent small-pox. CHYMIFICATION. 41 The corpuscles of the gastric juice are very tenacious of life, as are all similar secretions. In rennet, the dried stomach of the calf, they may retain their organic properties for years. One of the peculiar properties of gastric juice, is that of coagu- lating milk. Dr. Fordyce long ago ascertained that six grains of the mucous coat of the stomach, infused in water, will pro- duce a liquid that will coagulate one hundred ounces of milk, or 6,857 times its bulk. It has been ascertained that a single drop of gastric juice con- tains not less than half a million of corpuscles, and that the quantity necessary for the proper digestion of a single meal may be reckoned in figures at not less than 130,000,000,000 ; a number that need not surprise us when we recollect that modern scientists have estimated the constituent molecules of a drop of water at several billions. In a prize essay on Cheese-making, by S. R. Arnold, of Lansing, Michigan, published in 1870, the author claims that, in the ordinary process of cheese-making, the corpuscles, or cells, obtained from rennet, are not destroyed in the cheese, but are transferred to the stomachs of those who eat the cheese, and may there assist digestion ! But this is pushing nature quite out of the universe. If cheese, or anything else that contains gastric corpuscles, is necessary or useful in the digestive processes of the human sto- mach, how are those human beings going to digest their vic- tuals who have not cheese or something similar ? And how are the animals that never use any pepine except the home-made article, to get along ? Old cheese is well known to be one of the most indigestible articles that was ever swallowed in the name of food ; occasioning constipation of the bowels, canker in the mouth, dryness of the mucous surfaces, and deficiency in both the gastric and salivary secretions. Says the old dis- tich : " Cheese is a surly elf, Digesting all things but itself." Perhaps Mr. Arnold derived his philosophy from this couplet of the muse. But it is not truth, whatever may be said of the 42 DIGESTION. poetry. It is an unnatural and very unwholesome food ; in* deed, it is not food at all in the proper sense of the word, though containing certain alimentary proximate principles in an altered and degenerated form. B3cause cheese is a dry food, that is, contains little water, some English medical writers, in view of the scarcity and high prices of flesh-food, consequent on the " rinderpest, " "pleuro-pneumonia," and "rot," among so many of the cattle and sheep brought to the London mar- ket, have recommended cheese as a substitute. They will find a much better article of diet in that king of the cereals, wheat, provided they know how to cook it hygienically, or in any one of twenty grains, fruits, and roots that could be named. Another peculiar property of the gastric secretion has been called antiseptic. This term is not strictly correct, for antiseptic ap- plies properly only to dead matter. It is true, however, that partially decayed vegetables and semi-putrescent flesh, lose all offensive odor soon after coming in contact with the gastric juice. But this effect results from the trans- forming power of the solvent, by which the molecular atoms are re-arranged and the fetid gases decomposed and dissipated. All that an antiseptic can do is to prevent decay by rendering the organic elements fixed and un~ changeable, as with salt, vinegar, alcohol, arsenic, etc. This is why all salted aliments are more indigestible and less nutritious than those which are fresh. In Fig. 20, the entrance to the secreting follicles are shown, in the cells upon the surface of the mucous membrane of tta stomach. The mucous membrane is so completely studded with glands for the secretion of the gastric juice that its surface has a velvety or napped appearance, as represented in Fig. 19, which is a section of the coals of the stomach near FIG. 19. Gastric Glands. fig. 20. Secreting Tubes. CHYLIFICATION. 43 the pylorus, showing the gastric glands magnified twenty dia- meters. The immediate consequences of a deficient supply of gastric juice — a condition that exists with all dyspeptics — are, acidity, flatulence, eructations, water-brash, heart-burn, etc. After the food has been duly prepared in the stomach in the manner we have seen, it is passed through the pylorus (lower orifice of the stomach) into the duodenum, the first portion of the small intestines. The pyloric portion of the stomach and the upper portion of the duodenum are liable to become ulcerated, indurated, tuberculated, and even can- cerous in persons who have much abused their digestive or- gans with strong condiments, indigestible aliments, alcoholic liquors, or other poisons. CHAPTER VI. CHYLIFICATI02ST. In the duodenum the food, now chyme, is mingled with the secretion from the mucous membrane of the intestine itself, the bile, and the pancreatic juice. Physiologists do not yet agree as to the precise offices performed in the organic economy by the liver or pancreas. The bile is certainly, in part, and prob- ably wholly, an excrementitious fluid, or excretion, although being of an alkaline nature, it may incidentally mingle with the fatty matters of the food, and by converting them into a saponaceous mass, assist in their passage or absorption. All physicians are familiar with the various phases of disease which result from a deficient excretory action of the liver. Jaundice, rashes, humors, erysipelatous affections, dimness of vision, impaired hearing, and a multitude of cutaneous eruptions are attributable to "biliousness/' The following extract from the author's work, "The Hy- dropathic Encyclopcedia," may be pertinent in this place : "The liver forms the bile from the venous blood. The ob' ject of the biliary excretion evidently is to eliminate certain inv 44 DIGESTION. purities from the body in the form of compounds of carbon, hydrogen and nitrogen, and also ' to deterge the blood of a portion of any excess of alkali that may be absorbed by the ve- nous extremities. * ' Liebig has fabricated a" singularly inconsistent hypothesis, which has satisfied himself and all others who are satisfied to echo his arguments without taking the trouble to examine them, that the bile is a nutritive product, and that, conse- quently, whatever will tend to the formation of bile, or any of the proximate elements usually found in bile, is a useful and nutritive substance. Liebig reasons in this wise : The bile is composed of several certain proximate elements. One of these is called taurine. This taurine is the only compound or prox- imate element found in the bile which contains nitrogen. Now theine and caffeine, the active principles of tea and coffee, are found, on chemical analysis, also to contain a very small quan- tity of nitrogen ; ergo, tea and coffee, though injurious excit- ants to the nerves, may be useful to the liver by furnishing the nitrogenous element of the taurine of the bile. Such rea- soning is extremely absurd, and the error is a most palpable one. It consists in mistaking a waste material for an aliment ; a depurating process for a nutritive one. As well might one mistake putrid flesh for wholesome food, because it contains carburetted hydrogen, which is also found in the foeces, or ex- crementitious matters of the bowels." The pancreatic juice, mingling with the oily matters of the food, or with the food (and it should be stated here that oily matters are never digested nor changed in the stomach), redu- ces them to the condition of an emulsion, which means, dividing the oily particles so minutely that they lose their apparent individuality. In this emulsified condition the fat is capable of being absorbed and carried into the general circu- lation, and, finally, expelled through the various emunctories, or deposited in the cells of the areolar tissue.

From the commencement of the small intestines to the ter- mination of the large ones, the mucous lining of the canal secretes a fluid which not only smooths the passage of matters along its surface, but aids in the elaboration of the nutrient elements. In different portions of the alimentary tract there are special glands, follicles, or other secreting structures, aiding in the complex process of converting " pabulum " into living structures. The small intestines are divided by anatomists into the duodenum, jejunum, and ileum, and the large intestines into the cecum colon and rectum, A glance at some of the more 46 DIGESTION. prominent of these special appendages to the digestive apparatus will not only show how ' ' fearfully and wonderfully " we are made, but may induce us to have a little more compassion on our own bowels, if we cannot have ' ' bowels of compassion " for others ; for it is in the long and tortuous tract of the intestinal canal that the most aggravated mise- ries of a dyspeptic life are experienced. Choleras, colics, diarrhoeas, worms, hemorrhoids, various con- cretions, and, worst of all, constipation, have their seat in the intestinal tube, in addition to inflamma- tory affections and struc- tural derangements, which are common to all parts of the system. In Fig. 22, is seen a section of the ileum, in- verted, so as to show the appearance and arrange- Fig. 22.— Section of the Ilium. ment of the villi C!\ an ex- tended surface, as well as the follicles of Lieberkuhn. The follicles are represented by the great number of black points between the villi, or proiections, and can only be recognized by a close inspection. A section of the small intestine containing some of Peyer's glands, as shown under the microscope, is represented in Fig. 23. They secrete a milky fluid with numerous corpuscles of various sizes, but not so large as those of the blood. The meshes seen in the folds are the ordinary tripe-like folds of the mucous coat. Several late pathologists have advanced the theory that an inflammation of Payer's glands in '.he jejunum and ileum, is the INTESTINAL DIGESTION. 47 essential cause of typhoid, or enteric fever, while an inflamma- tion of Brunner's glands, in the duodenum, is the essential cause of typhus or putrid fever. But these theorists have mis- taken effect for cause. In some instances these glands were found inflamed or dis- organized after death. In other cases no such appear- ances were discoverable. If inflammation of these glands was the cause of these fevers, post-mortem examinations should have confirmed it in all cases. The entire number of follicles in the whole ali- mentary canal has been reckoned by Dr. Horner ( ' ' Special Anatomy and Histology, ") at " forty-six million nine hundred thou- sand and upwards. " They constitute the minute ana- tomy of the mucous coat, and their most prominent phases are represented in the four following illustra- tions : Fig. 24, is a view of the follicles of the colon, mag- nified one hundred and fif- teen times. Their aggre- Fig. 24 .-Follicles of the Colon. gate number is estimated at nearly ten millions. Fig. 25, is a view of the folds and follicles of the stomach, highly magnified. About two hundred and twenty-five are found on every square of an eighth of an inch, which would give a little more than a million and a quarter for the entire stomach. 43 DIGESTION. In Fig. 26, are seen the follicles and villi of the jejunum highly magnified. As the villi are erected by the injection, they run into each other and press one upon an- other like the convolu- tions of the cerebrum. The follicles and also the villi of the ileum, highly magnified, are represented in Fig. 27. These villi are curved, with their edges bent in, on concave. There is, however, in the whole alimentary canal, al- most every conceivable form and shape. It is in the large intestines, where fecal matters are liable to accumulate, that the most distressing effects of indigestion are man- ifested. Admirable as are their structural ar- rangements and irregu- larly curviform direc- tion for the performance Fig. 26.— Follicles of the Jejunum. of their functions Under normal conditions, these very circumstances render them liable to become the seat of terrible sufferings when obstructed or diseased. This fact may be inferred from a glance at the illustration, Fig. 28, which is a view of the position and curva- tures of the large intestines. The large intestines differ from the small in being saccu- lated, an arrangement which favors the retention of the nu- trient material which has not yet been taken up by the INTESTINAL DIGESTION. 49 Fig. 27. — Follicles of the Ileum. ried extremities of the veins and the lacteals, until it can be com- pletely absorbed, and also facilitates the excretion of fecal matters from the blood. But if constipation ex- ist, these sacculations become loaded with hardened fceces, and sometimes with other concretions, rendering the patient as miserabk as can well be ima- gined. It will be noticeo that the contents of the large intestines are ear- in a circuitous route, and in one place directly upward for ten or twelve inches ; thence across the abdominal cavity to the right side, thence down- ward on the left side to a posi* tion below the ileo-coecal junc- tion ; thence through the sig moid flexure (a curvature re sembling the letter S), and, 1.

The careless observer might see, in this extraordinary con*- trivance, nothing but a useless complication that renders the whole organism ever liable to manifold infirmities and prema- ture destruction. But a similar mistake has been made with t 50 DIGESTION. regard to the convolutions of the brain. There is neither sim- plicity nor symmetry on the encephalic surface, and its irre- gular elevations and depressions seem, to the non-philosophical mind, but a promiscuous and useless massing together of brain substance. But the physiologist, and especially the phreno- logist, sees the matter with very different eyes. He perceives the use, and then recognizes the beauty of the whole arrange- ment. He has learned that all of this unevenness of surface unfolds and spreads out, so to speak, the mental organs, and correspondingly augments their power. The last of the small intestines (ileum) opens into a large sac or pouch, which is the portion of the large intestine termed coecum. This is very large in some of the herbivorous animals. In the horse it is larger than the stomach. The careful student may inquire, for what purpose is the little tortuous worm-like appendage depending from the lower part of the ccecum ? Well, it has no physiological use whatever, and yet, paradoxical as it may seem, " nothing is made in vain." Like the little tri- jointed bone at the lower extremity of the vertebral column, it seems to point a moral. It is the relic of a lower organization, and is the strongest argument, perhaps, that can be adduced in favor of the doctrine of "Evolution." In some of the lower animals, which subsist on coarse food and herbage, the beaver, for example, the appendicula vermiformis constitutes another pouch or stomach, or a prolonged ccecum. As the food becomes more frugivorous and concentrated in the ascend- ing scale, the appendage is not needed, and perishes by non- use. If the human race exists long enough, and continues to develope in its cerebro-spinal tissue, the unseemly excrescence will entirely disappear. But I do not wish to be understood as interpreting * ' Darwinism " so as to make man the ' ' descendant " of the lower organizations. My opinion is that, in the order of progressive development he has ascended above the whole animal kingdom. A view of the whole range of the alimentary canal is presented in Fig. 29.

With the anatomical data before us, it is not difficult to understand why, in cases of prolonged constipation, or in tor- pid and feeble states of the alimentary canal and abdominal muscles, the ccecal pouch should be the portion of the canal 52 DIGESTION. most liable to obstructions and accumulations. Many persons of good constitutions, not conscious of any very bad habits, who live "as other folks do," and attend to their daily busi- ness, suffer continually of fcecal collections in the ccecum, and, generally, to some extent in the colon also, especially in that portion of it denominated the sigmoid flexure, without the least suspicion of the real cause of their difficulties. And physicians of extensive practice and long experience not unfre- quently dose such patients for years with aperients, cordials, stimulants, tonics, alteratives, nervines, and opiates, and some- times with mercurials in addition, with no thought of the nature of the troublesome symptoms. I have known several cases in which the lower extremities were so feeble and the back so weak, from no other cause than the one we are considering, that the patients could not walk without a cane in each hand. The ordinary symptoms are, a sense of weight or heaviness in one or both iliac regions, with occasional dull pains, alter- nating more or less frequently with aching or griping sensations. Sometimes the sensation in the part will be of a dragging or bearing-down character, in extreme cases amounting to a most intolerable tormina and tenesmus as in dysentery. All of these symptoms may be mild or severe according to the amount of excrementitious material present and the efforts made to dis- lodge it. Diarrhoea may also be present without removing the constipation, for the fcecal matters are often so hardened and impacted that fluid dejections pass by them without solving or moving them. Literary and sedentary persons are much more liable to obstructions of the ccecum and colon than are laboring persons. Clergymen, lawyers and legislators, who devote much time to writing or studying, and do not give proper attention to diet and exercise, are often extreme sufferers. Were it proper and useful to do so, I could give the names of distinguished bishops, divines, statesmen, lawyers, and even physicians, who have been dragged down from positions of honor and wealth, to moral degradation and poverty, because of this condition of their bow- els, and the medical treatment INTESTINAL DIGESTION. 53 I say medical treatment advisedly. The condition itself might have occasioned disease and even death. But it would not alone occasion dishonor. Opiates were given to relieve pain, and stimulants to ' ' support vitality. " Their effects were only temporary, and as the cause was not removed they were frequently repeated. Soon morphine and brandy became necessities ; and eventually drunkenness became a habit, fol- lowed in some instances by debauchery and other vices. Some of the readers of these lines may remember the sad story of two distinguished prelates, men of good name and fame and unim- peachable piety, occupying the exalted positions of Bishops of the two greatest States of our Union — New York and Pennsyl- vania. They were brothers. Both were degraded from their high and holy office for intoxication and lecherous conduct. The unfortunate men were more sinned against than sinning. It was shown on their trial that the medicine which had worked their ruin had been prescribed by their physicians. But, to say nothing of the various entozoa which are frequently found in different parts of the alimentary canal, all of which are scavengers, and could not exist were it not for the morbid secretions and improper ingesta, there is another group of ex- ceedingly distressing affections whose seat is the rectum. I mean hemorrhoids, or piles. Chronic inflammation of the mucous surface is among the effects of prolonged constipation, and this may extend from the mucous membrane of the coecum and colon to that of the rectum, or foecal accumulations may occur in the rectum. The result is, the numerous veins in the lower y part of this portion of the intestinal tube, very near its outlet, become distended into tumors, rupture and bleed, or the mucous membrane itself becomes disorganized, and portions of it are hardened with excrescences and tumors of various forms, sizes, and degrees of consistence. In these cases defe- cation is always painful, and the pain is sometimes excruciating. When these tumors are large or numerous, or the whole mucous membrane greatly relaxed, the tender and perhaps bleeding bowel will prolapse after each defecation, in many instances only to be replaced with difficulty and suffering. In 54 DIGESTION. extreme cases these tumors are removed by surgery— ligation 01 caustic Fig. 30. — Muscles of the Trunk, in Front. In Fig. 30 are seen the muscles of the trunk anteriorily.

INTESTINAL DIGESTION. 55 But the student who would master the complex physiology of digestion, should not overlook one important auxiliary which is scarcely alluded to in medical books, and not mentioned at all, so far as I know, by the standard authors on Theory and Practice, in connection with the therapeutics of indigestion. I mean the abdominal muscles. There is a good reason why the abdominal viscera, and especially the alimentary canal should not be enclosed within bony walls, as is the case with the brain and the organs of the thorax. The walls of the abdomen are formed of muscular and tendinous bands, which are thin, flexi- ble, and exceedingly strong. This structure provides for a great degree of mobility in the va- rious movements of the body, and aids powerfully in the peristaltic action of the bowels. In the act of defecation these muscles, co- operating with the action of the muscular coat of the intestinal canal, compress the whole abdo- men firmly yet steadily, so that the contents of the bowels are moved along and expelled easily and without pain. But when these muscles are inactive, from rigidity or relaxation, the whole effect is thrown upon the delicate fibres of the muscular coat of the intestines, resulting in imperfect or incomplete defecation, and, eventually, torpor and exhaustion of the peristaltic action.

Many ' ' wonderful cures " have been effected, of dyspeptics who had been dosed and drugged for years unavailingly, by simply exercising the abdominal muscles, by methods which will be explained hereafter. CHAPTER VIII. ABSORPTION OF THE NUTRIENT ELEMENTS. The nutritive elements o. the food are taken from the ali- mentary canal by the extremities of the veins, and by the lac- teal vessels, which originate in the small intestines. The process of absorption commences in the stomach and extends nearly or quite the entire length of the intestines. The venous absorbents convey their contents directly to the mass of blood, while the lacteal transport the matters which they take up through the mesenteric glands to the receptaculum chili, whence they are emptied into the blood near the heart. In the stomach the more watery portions of the aliment, and such elements as require little elaboration, are taken up by the extremities of the veins. When milk is taken the watery part is absorbed and the solid portions reduced to a coagulum, or curd, before gastric digestion can take place. The lacteal absorbents convey the more dense and oleagenous elements, termed chyle, which is usually of a milky white color; but this depends much on the quality of the ingesta, being nearly transparent in those who use little or no fatty matters in or with their food. A provision for the farther elaboration of the chyle is found in the mesenteric glands, which are convolutions of the absorb- ent vessels numerously distributed along their course. Fig. 32 is a view of the beautiful arrangement of these chyle- carriers. They are represented as injected. The arteries of the jejunum and mesentery are also injected.

All of the muscles 1 of the abdomen are auxiliary to respiration as well as to digestion. Indeed they constitute the chief forces in the act of expiration ; and without they are main- tained in a vigorous condition by appropriate exercise, neither breathing nor digestion can be well performed. In the act of vomiting the spasmodic contraction of these muscles is the main force that ejects the contents of the stomach, and in the various forms of cholera and diarrhoea, it is mainly the same force, ab- normally exerted, that causes the evacuations. Hence it becomes as necessary to regulate the action of these muscles in fluxes knd profluvia, as to invigorate them in cases of dyspepsia. Fig- 33- — Mesenteric Glands. 53 DIGESTION.

What precise changes the chyle un- dergoes in passing through the mesen- teric glands is not known, but as all glands are secreting, excreting, or elaborating organs, it is certain that the influence they exert on the nutri- tive fluid is important; hence it is essential to perfect digestion that these minute and complicated structures are not deranged nor impaired. And just here is another consideration of no small importance. It is said by some medical authors, that when mercurial and other mineral drugs come in contact with the mesenteric glands, they 4 'take on" inflammation. The phrase is absurd, but the meaning intended to be conveyed is, the medicine or poison (as it is administered with therapeutic or homicidal intent), occasions inflammation of the glands ; and the rationale is, the vital structures, recognizing the presence of an enemy within the vital domain, resist or oppose it by determining the blood to the part. The inflammatory process, however, although it ABSORPTION OF THE NUTRIENT ELEMENTS. 59 retards, does not prevent the passage of the drug ; for, as it is necessary for the chylous fluid to be passed along, the mineral particles which, in the form of oxides, chlorides, or salts, are exceedingly minute, pass along with it. The glands may be permanently diseased in this matter, and this method of getting drug-medicines into the blood is always more or less damaging to these delicate structures, and is the origin of most of the tumors which are seated in the mesentery, and which are be- yond the reach of medication or surgery. In some cases hun- dreds, and in other cases thousands of these glands are involved in the formation of an indurated irregular tumor and sometimes occupying a large portion of the abdominal cavity. If invalids must have their blood and tissues pervaded with the agencies of the drug shop, the safer way is to administer them hypoder- mically. By injecting them into the skin they will pass directly into the blood, and thus save the wear and tear of the digestive organs. When repeated doses of potent drugs are sent into the circulation through the long and devious route of the digestive apparatus, the effect is not unlike that of the march of an invading army through an enemy's country. If the aggressive forces put on their best possible behavior, they are enemies still, and more or less desolation will mark their track. And in view of the fact that we have, in the United States, thirty thousand drug shops, and seventy-five thousand physicians, furnishing the supplies and prescribing the doses, it may be a fair question for a debating lyceum, whether there is more dyspepsia pro- duced by drug medication than by all other causes combined ? CHAPTER IX. AERATION OF THE EOOD ELEMENTS. But the processes of digestion are not completed until the nutrient material reaches the lungs. In the respiratory organs, it receives its finishing elaboration, which fits it for assimilation. And here is another consideration for dyspeptics which is set 6o DIGESTION. dom sufficiently regarded, if, indeed, it is ever thought of. No food can be assimilated unless properly aerated. Each particle of food must come in contact with a particle of atmospheric air, or it can never be used — else it is worse than useless. For this purpose it is diffused through the lungs with the blood which is there decarbonized. All of the venous and lacteal absorbents, as we have seen, convey the nutrient matters which they take up from the stomach and small intestines to the right side of the heart, as do all the venous extremities and lymphatics which originate in the large intestines. From the right side of the heart it is conveyed, with the venous blood from all parts of the system, to the lungs. The function of aeration is not fully understood. It is well known that in respiration the blood is purified of its effete car- bon, and that oxygen is received into the system. But it is not known that oxygen performs any other office than to com- bine with and reduce to ashes, and thus favor the expulsion of the disintegrated or dead matters. Oxygen is usually termed " vital air," but I suppose the vitalizing element is something very different. So far as we can trace the effects of oxygen, they are purely destructive. Of course it is just as important to get rid of the offal, to remove the effete matters from the system, as it is to supply wholesome food. And for this purpose a full supply of oxygen is a vital condition. But this does not make it in any sense " vital air," any more than nitrogen is vital air, for a due admixture of this gas with the oxygen is just as essential to health as is the presence of the oxygen. Pure oxygen is as non-respirable as is nitrogen, carbonic acid gas, or hydrogen ; although a larger proportion of it in the atmosphere than nature provides may be borne for a time with- out serious inconvenience. Those empyrics, however, who run the business of treating diseases with "Compound Oxygen,,, "Super-Oxygenated Air," "Vitogen," and other humbugs, must either be arrant ignoramuses, or have great faith in human credulity. These enterprising gentlemen might as well under- take to invent better kinds of food, or a superior quality of AERATION OF THE FOOD ELEMENTS. 6l water than nature has been enabled to accomplish, by chang- ing the proportions of their constituent elements, as to imagine they can improve the atmosphere nature has provided for us to breathe. In my opinion the vitalizing principle which may pervade any organic structure, and which is especially received in respi- ration, is an element inconceivably more refined than oxygen or its nascent condition, ozone, and more etherealized than even the all-pervading electricity or magnetism, and which fills all that part of the unmeasurable universe which is called space. But, for all practical purposes it is enough to know that perfect respiration is essential to perfect nutrition, and that every influ- ence which diminishes the breathing capacity, correspondingly impairs digestion and conduces to dyspepsia. All impurities of the atmosphere tend to enfeeble the respira- tory, and indirectly, the nutritive functions, as do all habits of dress or positions of body which impede the action of the respi- ration. And here I must allude to two prevalent causes of dys- pepsia, consumption, and general physical deterioration, which are not only destroying the young men and young women of our land at a fearful rate, but are alarmingly on the increase all over the country. I cannot do better justice to this branch of our subject than by quoting a few paragraphs from one of my works on ■ Tobacco-Using," recently published at the office of the Health Reformer, at Battle Creek, Michigan : ' 1 THE BREATH OF LIFE. "There is one view of the physical evils of tobacco-using which has never been presented distinctly by writers on this subject. I mean the effect of the habit of respiration. Tobacco- using directly and fearfully lessens the breathing capacity. This is one reason why tobacco-users require more sleep than others, other circumstances being equal.* Now, the available life- * The less the nervous energies are exhausted by nervines, stimulants, or narcotics of any kind, or, indeed, by pernicious habits of any sort, the less will be the amount of sleep required for recuperation. 62 DIGESTION. force of every living being is precisely in the ratio of the devel- opment of the respiratory organs. Tobacco-using, so long as it is continued, constantly diminishes the breathing apparatus. This is easily explained. Any one, on going, on a hot sum- mer's day, from the stifling stenches of an uncleaned city, to the purer breezes of the open country, may have a realizing sense of the principle involved. His lungs will expand spontane- ously. They seem to open full and deep to take in as much vital air as possible. It is a luxury to breathe. But in the dirty city, the accumulated impurities of the atmosphere are resisted by the pulmonary structures. The glottis partially closes to keep them out, and all of the respiratory muscles contract spasmodically to prevent their entrance. Breathing is, therefore, imperfect. And when the atmosphere is very impure, breathing is not only imperfect but painful ; and in extreme cases it is entirely suspended. ' ' Now, nothing is more offensive to the vital instincts of the respiratory organs than the odor and fumes of tobacco. Talk about stenches, miasms, contagions, infections, from gutters, cess-pools, markets, stables, distilleries, tenement houses, offal gatherings, &c. ! All of them combined (let me gently hint to the Board of Health) do not equal tobacco in intrinsic repul- siveness, nor in their injurious effects on the lungs. ' 1 Let any one, uncontaminated by its use, enter a close room where several persons are smoking, or a crowd in the street where fashionable young men most do congregate, and, in a moment, he will find himself breathing short and laboriously. He will experience a sense of suffocation, and perhaps feel an inclination to sneeze, retch, or vomit. His lungs expand with , difficulty. They do not kindly receive the particles of the deadly narcotic. Inhalation is feeble and imperfect, while ex- piration is more forcible and complete. And thus the lungs are exercised in just the manner gradually and surely to contract the diameter of the chest and permanently diminish the respi- ratory capacity. And as our whole population is more or less exposed to an atmosphere strongly impregnated with tobacco effluvia, the vital function of respiration cannot fail to suffer a AERATION OF THE FOOD ELEMENTS. 63 continual deterioration. And all that is necessary to insure the ruin of the human race at no distant day is the increase of the habit of tobacco-using as rapidly as it has increased for three centuries past, or as rapidly as it is increasing at the present time. Frightful examples of this possible result may be seen in droves in all of our cities and large villages. 4 4 Look at the swarms of young men — young in years, but old in vital conditions — who commenced this horrid practice in early life ; and thousands do commence it even before the age of puberty. The close observer will not fail to notice in a ma- jority of them, something unshapely and unhuman — 4he sharp features, angular faces, projecting shoulders, lank limbs, nar- row chests, gaunt abdomens, sallow, bilious skin, and old-man- ish appearance generally. To the eye of the intelligent phy- siologist these young men — mere boys in the order of nature — are prematurely old, already in a decline. I have seen thou- sands of tobacco-using young men (of twenty to twenty-five years of age, according to the almanac) who were physiologi- cally and for all practical purposes, older than thousands of their fathers and grandfathers were at fifty to sixty years of age. A large proportion of tobacco-using young men are dwarfed in body and mind irrecoverably ; and should they unfortunately become husbands and fathers, their wives may well be pitied, while their offspring will in most cases be constitutionally frail and precociously dissolute, and many of them imbecile, if not idiotic. " Many of these young men have the characteristics of disso- luteness and sensuality stamped indelibly on the physiognomy as well as the physiology. And with many of them — indeed all, to a greater or less extent — their secretions are all morbid, their excretions defective ; their whole mass of blood foul, their breath fetid, their sweat nauseous, and their whole persons offensive. " young men the chief smokers. "As we trace the history of tobacco-using from one genera- tion to another, it is all downward — from bad to worse. The 64 DIGESTION. fathers of many of the tobacco-using young men of the present day did not commence the habit until they had acquired a fair vital development. But they transmitted morbid propensities to their children, who commenced much earlier in life. Hence there is frequently a striking contrast between the compara- tively stalwart tobacco-using father, and the puny, fragile, stunted, and inferior tobacco-using son. It is not difficult to imagine what their sons must be. "It is worthy of remark that, as a general rule, persons who become addicted to tobacco-using (and the same is true of liquor-drinking) in early life, indulge more excessively than do those who commence in middle or mature life. Being excitable, the consequent depression is greater ; hence the seeming necessity for more frequent repetitions. " A few days since, I noticed an illustration of this statement, which will, I think, be found of extensive application. I was travelling from Philadelphia to New York. The car in which I was seated contained just forty persons. Eight of them were young men ; twenty-two would pass for middle-aged, and ten were old persons — six men and four women. All of the young men (and this was not the " smoking car, forward") smoked cigars or huge meerschaums more than half of the whole dis- tance ; only two of the middle-aged men smoked at all, and then cigars only on one occasion for a few minutes ; while but one of the old gentlemen befouled himself and the rest of us by smoking at all. I have made similar observations on all the leading railroads of the United States, and I am of the opinion that if any person, travelling in any part of the country by rail, steamer, ferry, or stage, will study this subject closely, he will find that the principal smoking is done by the young men. Tens of thousands of young men may be seen every Sunday standing around the corner groceries, and the thousands of tobacco shops (which find Sunday their principal business day of the week), smoking their lives away, and bestenching the atmosphere which others are obliged to breathe. And in every public gathering outside of a church, it may be readily noticed TOBACCO-USING. 65 that the principal smoking is performed by the young men and boys. i ' Tobacco-using, in young persons, has the same effect in diminishing the breathing capacity that tight-lacing (which is alarmingly on the increase again) has. Some years ago, when the practice of tight-lacing, which has ruined many thousands of young ladies, induced the friends of humanity and of the future generations, to make special efforts to arrest the evil, many young men adopted the maxim, 'natural waists or nc* wives/ It is a pity the maxim was not more generally lived up to. But these young ladies might very well reciprocate the compliment while they accepted the philosophy in adopting the adage, ' natural mouths or no husbands. ' Examples are, in- deed, sadly frequent on the thoroughfares of our great cities, of young ladies who have destroyed more than one-half of their breathing capacity by this disgraceful habit of tight-lacing. They cannot possibly live to be old ; they can never become mothers of healthy children ; and while they do live they must be infirm and miserable in themselves, and a source of anxiety and sorrow to their friends. They are invalids for life. Their wan, expressionless faces, harsh, pinched, contracted features, with livid, bilious discolorations of the skin, proclaim in lan- guage that the physiologist cannot mistake, deficient respiration and imperfect depuration. And the counterpart of these appearances and indications may be seen in numerous young men who promenade the streets behind lighted cigars. 4 'But although the physiological result is the same in the cases of tobacco-using young men and tight-lacing young women, there is a considerable difference anatomically. In the case of the young ladies the obstruction to respiration is external and mechanical, hence there is greater deformity, or ' caving in/ of the vital organs, while, with the young men, there is less malformation or deformity of the chest. "Let a tobacco-using young man and a tight-lacing young woman marry, and what must be the character of the off- spring ? We can see melancholy specimens enough on every hand. 66 DIGESTION. 1 ' Now the only method which has ever proved effectual for preventing or curing consumption is, to keep the lungs ex- panded as much as possible. And for this purpose, breathing tubes, spirometers, blow-guns, lifting machines, and other gymnastic contrivances, have been found useful. A LEARNED DISCUSSION ON TOBACCO. f< I cannot better illustrate the delusion that may exist in high places, even among the learned, on the subject of tobacco- using, than by the relation of the following incident : In 1862, I attended the annual meeting of the British Scientific Associa- tion, in Cambridge, England. In the section on Physiology, a paper was read on the evil effects of tobacco-using. The author stated very clearly the various morbid conditions and diseases which are well known to result from the habit, and quoted a respectable array of medical authorities who declared it to be extremely pernicious. The discussion that followed the reading of the paper was amusing, if not instructive. Every one who spoke on the subject (and they were all medical gen- tlemen), condemned, not the tobacco, but the author of the essay! ' He was not a competent judge/ 'His opinions were of no authority/ ' He was no physiologist,' etc. All who spoke, advocated the use of tobacco — moderately, of course. One gentleman said that, ' next to alcohol, tobacco was the best-abused article in existence. ' Another stated that he had used the ' weed ' for twenty-three years without being harmed by it. A third regarded it 'favorable to mentality,' a fourth considered its employment in moderation ' decidedly hygienic. ' A fifth said, ' I always find my ideas to flow more consecutively after a few whiffs from a good cigar ;' and a sixth justified its use by reference to the Turks, ' who used tobacco freely, yet were a strong and courageous race. ' No one replied a word to the facts, or pretended to meet the arguments pre- sented in the paper ; but all who spoke, contented themselves with the utterances of opinions in praise of tobacco, and de- nunciations of the author. Surely, if an association of scienti- fic men whose members claim to be as learned a body as exists TIGHT-LACING. 67 on the earth, can gravely utter such arrant fallacies, we need not wonder at the wide-spread ignorance of the non-professional people on this subject. The importance of the subject of tight-lacing, and abnormal positions when habitually assumed, as affecting respiration and digestion, cannot, perhaps, be better stated and illustrated than in the following chapter on ' ' Popular Physiology," a serial work now being published in the ' ' Science of Health. " The illustrations are from a work by the author, entitled, "The Illustrated Family Gymnasium." BODILY POSITIONS. ' 1 A single glance at the situation of the various organs of the body, with respect to each other and to the bony skeleton, shows the importance of maintaining, under all circumstances, the normal position. Erectitude is one of the most obvious laws of the vital machinery, yet almost every one is crooked. 'Blessed are the upright/ physically as well as morally. "Each structure and organ is provided with all the room necessary for its functional purposes, but no more. Nature is a rigid economist. She never wastes. She provides the ma- chinery of life, and the conditions for its normal operation. Obey the law and live, disobey and die — these are her irrepeal- able mandates. The vital organs have definite relations to everything in the universe. Observe and conform to these relations and be well ; disregard them and suffer. Such is the stern teaching of Nature's volume, but it is also benevolent. If laws can be disregarded with impunity, they are practically annulled, and exist in vain. Nature commits no error in the enactment of law, and provides no remedies for their infraction. Suffering is inevitable so long as we act in disobedience to the laws inherent in the vital organism. Unless this were so we could never learn to obey the laws. Experience may be a dear school. The penalties for transgression may be terrible. But neither is too costly or severe until it teaches us the greatest practical truth that the human mind is capable of comprehend- 68 DIGESTION. ing — that all good is in the line of obedience to organic law, and all evil in opposition thereto. " 'Cease to do evil and learn to do well ' in all things, is the divine philosophy, and applicable to every department of human life. In few things are human beings more prone to do evil and more regardless of all health considerations than in respect to bodily positions. 'Just as the twig is bent the tree's inclined. ' " A great majority of children in our primary schools become more or less abnormally inclined in manhood, because they are bent out of shape in childhood by unhygienic seats and benches. "In the cut ^Fig. 35 ; are seen the situation and relations of the principal internal organs of the body. " The important lesson deducible from the illustration before us is, that in all of our exercises, active or passive, we should maintain the normal positions of the organs. In lying, sitting, standing, walking, running, working or playing, use the joints, and never bend or compress any other organ, part or struc- ture. "It is evident that, if the body is habitually bent so as to approximate the heart, A, and stomach, D, or if the chest is restricted by lacing, so as to lessen the diameter of the chest in the region of the diaphragm, d, every organ of the thoracic and abdominal cavity is more or less compressed, and most of them actually displaced. "The horrid effects of tight-lacing (quite as ruinous to young ladies as tobacco-using is to young men), or of lacing at all, and of binding the clothing around the hips, instead of sus- pending it from the shoulders, can never be fully realized with- out a thorough education in anatomy and physiology. And if the illustrations here presented should effect the needed reform in fashionable dress, the resulting health and happiness to the human race would be incalculable ; for the health of the mothers of each generation determines, in a very large mea- sure, the vital stamina of the next. TIGHT-LACING. 6 9 "It is obvious that, if the diameter of the chest, at its lower and broader part, is diminished by lacing, or any other cause, to the extent of one-fourth or one-half, the lungs, B, B, are pressed in towards the heart, A, the lower ribs are drawn together and press on the liver, C, and spleen, E, while the ab- dominal organs are press- ed downward, D, on the pelvic viscera. The stomach, B, is compress- ed in its transverse diam- eter; both the stomach, upper intestines and liver are pressed downward on the kidneys, M, M, and f on the lower portions of the bowels (the intestinal tube is denoted by the letters, yy, and k), while the bowels are crowded down on the uterus, t, and bladder, g. Thus every vital organ is either functionally obstructed or mechanically disordered, * and disease, more or less aggravated, the condition of all. In post-moriem examinations the liver has Fig. 35.— Internal Viscera. been found deeply indented by the constant and prolonged pressure of the ribs, in consequence of tight-lacing. M The brain-organ, protected by a bony inclosure, has not yet been distorted externally by the contrivances of milliners and mantua-makers ; but, lacing the chest, by interrupting the cir- culation of the blood, prevents its free return from the vessels 70 DIGESTION. of the brain, and so permanent congestion of that organ, with constant liability to headache, vertigo or worse affections, be- comes a ' ' second nature. And this condition is often aggra- vated by heavy water-falls, chignons and other ridiculous head- gear. " The vital resources of every person, and all available pow- ers of mind and body, are measurable by the respiration. Precisely as the breathing is lessened, the length of life is shortened ; not only this, but life is rendered correspondingly useless and miserable while it does exist. "It is impossible for any child, whose mother has dimin- ished her breathing capacity by lacing, to have a sound and vigorous organization. If girls will persist in ruining their vital organs as they grow up to womanhood, and if women will continue this destructive habit, the race must inevitablj deteriorate. It may be assert- ed, therefore, without exaggera- tion, that not only the welfare of the future generations, but the salvation of the race de- pends on the correction of this evil habit. 4 4 The pathological consequences of continued and prolonged pressure on any vital structure are innutrition, congestion, inflammation and ulceration, resulting in weakness, waste of substance and destruction of tissue. The normal sensibility of the part is also destroyed. No woman can ever forget the pain she endured when she first applied the corsets ; but in Fig 36 — Anterior View of the Tho- rax in the Venus of Medicis. TIGHT-LACING. 71 time the compressed organs become torpid ; the muscles lose their contractile power, and she feels dependent on the me- chanical support of the corset. But the mischief is not limited to local weakness and insensibility. The general strength and general sensibility correspond with the breathing capacity. If she has diminished her ' ' breath of life," she has just to that extent destroyed all normal sensibility. She can neither feel nor think normally. But in place of pleasurable sensations and ennobling thoughts, are an indescriba- ble array of aches, pains, weaknesses, irritations, and nameless distresses of body, with dreamy vagaries, fitful impulses and morbid senti- mentalities of mind. " And yet another evil is to be mentioned to render the catalogue complete. Every particle of food must be aerated in the lungs be- fore it can be assimilated. It follows, therefore, that no one can be well nourished who has not a full, free and unimpeded action of the lungs. ' ' The effects of improper dress on the bony skeleton, and especially on the spinal column, are shown in Figs. 36, 37. 38, and 39, which every physician knows are not over- drawn. 4 'In the contracted chest, represented by Fig. 37, (by nu means an uncommon case), the external measurement is re- duced one half; but as the upper portions cf the lungs cann«H Fig. 37 — The Same in a Lady Deformed by Stays. 72 DIGESTION. be fully inflated until the lower portions are fully expanded, it follows that the breathing capacity is diminished more than one-half. It is wonderful how any one can endure existence or long survive, in this de- vitalized condition ; yet thou- sands do, and, with careful nursing, manage to bring into the world several sickly children. "The spinal distortion ( Fig. 39) is one of the ordi- nary consequences of lacing. No one who laces habitually can have a straight or strong back. The muscles being unbalanced, become flabby or contracted, unable to support the trunk of the body erect, and a curvature — usually a double curva- ture — of the spine is the consequence. "And if anything were needed to aggravate the spi- nal curvature, intensify the compression of the internal viscera, and add to the general deformity, it is found in the modern contrivance of stilted gaiters These are made with heels so high and narrow that locomotion is awkward and pain- ful, the centre of gravity is shifted 'to parts unknown,' and the head is thrown forwards and the hips projected backwards to maintain perpendicularity, rendering walking and all other voluntary exercises not only distressing to the person, but dis- agreeable to the spectator. ' ' To sit or stand in a crooked position, inclining the head and knees forwards, overstretches the middle spinal muscles, re- verses the normal curvature of the spinal column, compresses Fig. 37.— Posterior View of the Thorax in a> -natural state TIGHT-LACING. 73 the liver, stomach and lungs, and is in effect equivalent to lac- ing the waist. Figs. 40 and 41 show the right and wrong positions in standing. " Sleeping on two or three pillows, or on a bolster and pillow, is a prevalent yet per- nicious custom. If long con- tinued the effect is surely a distortion of the spine to some extent. If the head is raised high while sleeping, the stom- ach and lungs are injuriously compressed, and the upper in- testines pressed downward on the pelvic organs. If children , are allowed to sleep habitually j on high pillows, spinal curva- ture and general debility will be the inevitable conse- quences. One pillow is enough for any person, and that should be only of mode- rate size. Figs. 42 and 43 exhibit the right and wrong positions in contrast. ' 'Malpositions in sitting seem to be among the increasing evils of high civilization without physiological education. This habit is mainly attributable to the immensely unanatomical construction of chairs, benches, sofas, pews, etc. Not one school-house in all the land, not excepting those in which physiology is professedly taught, has a chair or a bench that a child can sit upright on without a constant and consciously painful effort. Nor have we ever seen, in private families or public institutions, halls or churches, stages or ferry-boats, rail- road cars or steamers, a single seat constructed on hygienic Fig. 39. — Distorted Spine. "4 DIGESTION. principles. Figs. 44 and 45 show the normal and abnormal positions. Fig 40— Standing Erect. Fig. 41. — Malposition. Children who early acquire and continue in the habit of sit- ting in normal or abnormal positions will either preserve the erectitude of the spinal column as shown in Fig. 46, or become crooked-backed, as seen in Fig. 47. It is apparent that, inclining the head forwards and bending the body at the middle of the back, instead of on the hip-joints, necessitates a backward projection of the entire spinal column r with a corresponding incurvation or pressure anteriorily ; hence the whole body is distorted from the crown of the head to the soles of the feet ; more than a hundred muscles are un- balanced, and every organ and limb is weakened. In all exercises, in walking, running, lifting, and in manual labor, the power of the individual is always determined by the POSITION. 75 number of muscles that are brought into co-operative action. But if the body be crooked, or any part of it out of the norma] relation to other parts, some muscles will be strained by over ac- tion, while others will become relaxed from insufficient action, and all weakened — just as in the crooked ways of society some persons are drudged to death while others die of indolence.

But the com- 46— Natural Spine. 47 — Distorted Spine. mercial articles reverse this rule ; they press unduly on the upper part of the thighs and the upper part of the back, and afford no support whatever where it is principally needed. Moreover, in addition to the defective shape, they are, on the average, two inches too high, rendering it impossible for the feet to rest evenly and easily on the floor. No wonder that, on chairs which are a torment to one who tries to sit erect, per- sons are continually leaning back against the wall, drawing up their feet, placing one foot across the opposite knee, brac- ing one or both feet against the chair rounds or any adjacent object, and getting into all sorts of uncouth and ridiculous attitu Jes. The cut (Fig 48) represents the outline of our ideal chain POSITION. 77 7 Fig. 48. The Anatomical Chair, We place it on record for the benefit of the future generations, in the hope that some ingenious mechanic or pecunious philan- thropist will supply one of the great wants of the age by introducing it." As normal sensibility is intimately con- nected with respiration, the depression and melancholy so common to dyspeptics whose chests are contracted, are readily accounted for. Many of these invalids have, by tight- lacing or other unhygienic habits, so changed the form of the chest as to render it concave in front where it should be round and full, thus preventing the descent of the diaphragm in inhalation and ren- dering a full inflation of the lungs impos- sible. In the illustration (Fig. 49), which is a side view of the chest and abdomen in respiration, the importance of the unimpeded mo- tion of this muscular structure which divides the cavities of the thorax and abdomen may be re- cognized at a glance. 1.

Action of the Diaphragm. much more predisposed to consumption. I>et us complete the illustration by contrasting the forms of features of one who has, by tight-lacing, acquired the abnormal 78 DIGESTION. shape of the chest, with its necessary accompaniment of a wan, dejected, and expressionless face, (Fig. 50,) and a ' 'human form divine," whose breathing capacity and life-resources are shown in a full expanded respiratory apparatus, and a correspondingly vitalized, hopeful, and intelligent countenance — such as sculptors and painters delight to fash- ion and exhibit in marble and on can- vas, and such as admiring crowds will gaze upon for hours with pleasure. Those persons who are distinguished as having a "fine flow of animal spi- rits, " invariably have a free play of the Fig. 50— Unnatural Waist, respiratory system. The blood being well purified and the food elements properly aerated, the circu- lation is well maintained on the surface, and the patient is not disturbed by nor sensitive to slight changes of temperature, nor chilled with an easterly wind or the fog of a morning, as is the case with those who do not breathe sufficiently. And these half-breathing mortals are always feeling the need of some artificial support, and are hence more liable to resort to various stimulating viands and pungent condiments, which only mitigate their sufferings temporarily, to be followed by collapse and augmenting debility. The editor of a monthly periodical, ("Hall's Journal of Health/') some years ago advanced a theory on the relation ot respiration to consumption as novel as it was absurd. And as the author has written a book on consumption, and sells medi- cines for consumption through the press, and, moreover, as his journal has attained a large circulation, and is often quoted as good authority by country newspapers, his ingenious views are worthy of a passing refutation. Briefly stated, the new and original theory amounts to just this : 1. Consumption is tuberbulosis of the lungs. 2. Tu- berculation of the lungs usually commences in the upper por- tion. 3. A due expansion of the lungs prevents the formation POSITION. 79 of tubercles. Ergo, By constricting the lower portion of the lungs, as by tight-lacing, the upper portions of the lungs are forced to do the breathing which the lower portions are pre- vented from doing, and hence tight-lacing and such other machinery or habits as diminish respiration in the lower part of the lungs are remedial. They are both preventive and curative of consumption. Ridiculous as this reasoning may seem to any tyro in physi- ology, it has appeared so plausible to some invalids that they have been misled by it. But a little deeper insight into the anatomy and physiology concerned will at once dissipate the delusion. The competent physiologist well understands that, in the act of respiration, the lower portions of the lungs are always expanded before the upper portions can be filled with atmospheric air ; hence whatever tends to restrict inhalation in their lower portions must inevitably diminish still more the respiratory capacity of the upper portions, and favor tubercula- tion. If the 10,387 deaths which occurred in New York in 1872, of the four diseases most immediately connected with respiration, viz., consumption, scrofula, pneumonia, and bronchitis, a large proportion of whom were yaung women, do not point the proper moral on this subject, then there is no use in mortuary statistics. The greater prevalence of dyspeptic and consumptive diseases among women than men has caused some medical writers to theorize that the explanation is to be found in original frailty. But the contrary is true. In the normal condition woman has the stronger vital and nutritive temperament, and is, constitu- ionally, less predisposed to either consumption or dyspepsia than man. There is a necessity and a reason for this. She is provided by nature with a nutritive apparatus not only compe- tent to nourish and sustain her own structures, but also able to develop and nourish offspring. My opinion is, that, if men would dress as the majority of women in fashionable life do, there would be ten cases of consumption among them where there is one now. Another very prevalent source of dyspeptic conditions in 8o DIGESTION. youth, resulting very frequently in consumption soon after ma- turity, if not before, deserves special mention in this place, for the special reason that it is never mentioned in medical books, and seldom thought of by parents and teachers. I mean our common schools. We are accustomed to impute our progress, morality, and intelligence, to our churches and schools. This is true, with some grains of allowance. But these drawbacks are very serious ones. Most of the school-houses in our cities, and not a few in the country, are pest-houses, very much in the sense that tenement houses are. They are not properly warmed in winter, and not properly ventilated at any season. They are too hot or too cold in winter, and too redolent of miasm in the summer. The scholars cannot get fresh air in cold weather without a chilling draft, nor pure air in warm weather under any circumstances. Many a private mansion, occupied by half-a-dozen persons, has more of the " breath of life " circulating through its rooms, than have some of our ward school-houses where several hundred children are tortured into "book knowledge," at the expense of vitality. As the air in the room where fifty or a hundred children are crowded toge- ther, is constantly vitiated by the exhalations from the skin and lungs, it is impossible, in cold weather, to ventilate sufficiently from the doors and windows without rendering the atmosphere in various parts of the room too variable and uneven for health. The only proper method of warming school-houses — and the plan is equally applicable to churches, public halls, theatres, etc. — is to have the fresh air conveyed from the outside of the building, or from the hall within, through a tube or pipe under the floor, to be discharged under the stove, or better still, into the cylinder or air box adjoining the stove, so that the air could be warmed before being diffused through the room. This arrangement would secure a uniform temperature, and purify the air without occasioning unwholesome or even unpleasant currents. When buildings are heated by steam the same arrangement for supplying fresh air is equally desirable, the outer air being admitted under or adjoining the radiating coil or plates. POSITION. 81 Moreover, school-children are, as a rule (I know of no ex- ceptions), made to "sit still" too many hours in the day, and on unhygienic seats at that. Not one growing child in ten can be confined in a school more than three hours a day without suffering more or less of debility and endangering life. Our sys- tem of forced education — developing brain, or trying to, before there is a physical basis — is all wrong, and is filling the land with educated imbeciles — I mean young persons who have information and accomplishments, but are useless to themselves and a burden to others, because of ill-health. I regard school- houses as among the worst causes of the general frailty, dys- peptic tendencies, and consumptive sequaela that are said to be peculiarly A» ttic in. Abbor Moeborum. DYS P EPSIA,. PART II. DYSPEPSIA. CHAPTER X. NATURE OF DYSPEPSIA. As digestion is the most complex of all the organic processes its derangements, which constitute indigestion, or dyspepsia, are the most complicated of all morbid conditions. Patho- logically it may be said to be the sum of all chronic diseases, as fever may be said to be the aggregate of all acute diseases ; for there is not a symptom in all of the one thousand diseases which make up the nosology, that is not found in some form, state, or stage, of both dyspepsia and fever, with the single exception of those which appertain to structural lesions. If all the "phenomenology" which the confirmed dyspeptic experi- ences in six or twelve months were suffered in the period of twelve or twenty-four hours, the disease would be termed fever, instead of dyspepsia ; and if the symptoms which belong to a paroxysm of fever, and which mark its cold, hot, and sweating stages, were extended over a period of some weeks or months, the disease would be termed dyspepsia instead of fever. In Doth cases the inability to nourish the body sufficiently is a leading feature of the morbid manifestations ; but in fevers, properly so called, the power of digestion and assimilation is wholly suspended in the early stage, while in dyspepsia it is only impaired. It is a great mistake to regard dyspepsia as peculiarly or especially a disease of the stomach. We have seen, in the preceding explanations and illustrations, how essentially co- NATURE OF DYSPEPSIA. *3 operative are a multitude of organs and structures in the digestive processes. And they are just as co-implicated in the derange* ment of these processes. In some cases one structure or organ will be more obstructed, impaired, or deranged than others, and in other cases two or more will be the seat of the more trouble- some symptoms. Thus, one dyspeptic may have one of several morbid conditions of the liver, as torpidity, congestion, indu- ration, chronic inflammation, gall-stones, or abscess, as the special complication of his case, and attended with jaundice, difficult breathing, or palpitation, a sense of weight, tenderness in the right side, spasms near the pyloric orifice, or throbbing pains, as the most prominent symptom. Another will have great distress, " goneness," acrid eructations, sick headache, a cramp in the stomach, because of the acid and putrescent bile which is occasionally emptied into the duodenum just below the pit of the stomach. A third may have constipated bowels, and a fourth diarrhoea, and a fifth these states interchangeably, as the most troublesome manifestation of the general ailment ; a sixth may have the vessels of the head so clogged with viscid blood as to experience more headache, either constant or periodical, than anything else to complain of; a seventh may feel great distress after eating ; an eighth, frequent paroxysms of \nausea and vomiting ; a ninth, capricious or craving appetite ; a tenth loss of all appetite ; an eleventh, canker in the mouth, or stomatitis; and a twelfth, general prostration, hypochondria, or nervous debility, as the more distressing part of his case. Many dyspeptics suffer in all of these ways, and have the symptoms \ above enumerated as changeable as the winds, and quite as uncertain with regard to rules for calculation as the weather " probabilities." Medical authors generally assign " weakness of the stomach " as the essential proximate cause of dyspepsia. They might as well say, weakness of the head, or heart, or hands, or feet ; all are weak when the digestive processes fail to supply the ele- ments of strength ; and the debility of the stomach or other digestive organs, in any case of dyspepsia, is no greater and no worse than that of all other parts of the body. Indeed, the 84 DYSPEPSIA. difference is just the other way, for nutrition, being the first and last process of organic life, all other parts of the system are disproportionately debilitated when the digestive function is impaired. Dyspepsia is, therefore, but a name for universal physical deterioration, although the symptoms of the general condition may embrace all the aches, pains and distresses that our language can express. The error of regarding dyspepsia as a local disease instead of a constitutional infirmity, leads to the mischievous practice of local medication ; and the weak stomach is excited with stimu- lants, urged with tonics, soothed with nervines, quieted with opiates, and modified with alteratives, while the other "chy- loipcetic viscera," especially the ever-involved liver, are treated to mercurials, not forgetting to remind the bowels of their re- missness of duty by a succession of purgatives. These are excellent methods for curing dyspepsia by killing the patient, or to mitigate symptoms, by destroying vitality. Professor George B. Wood, M. D., of Jefferson Medical College, Philadelphia, is the author of the latest and largest American work on the Theory and Practice of Medicine. In this work (" Wood's Practice of Medicine"), which is a text- book in our medical colleges, the author informs us that, "The most prolific source of dyspepsia is probably the com- bined influence of sedentary habits and errors of diet." This being the case, it would surely seem that the combined influence of appropriate exercise and a correct dietary ought to be the sufficient remedies. The Professor does indeed tell many things useful in the list of eatables and drinkables, and some articles of each class to avoid, but the strange part of the story is that he recommends, on his own reputation, or com- mends on the opinion of other authors, in the treatment of dyspepsia and its incidental affections, no less than a dozen classes of medicines, and more than one hundred individual drugs, to say nothing of the unmentioned ingredients in the compounds, and the bleeding and blistering processes. The individual remedies are, ipecacuanha, rhubarb, aloes, castile soap, croton oil, Cheltenham salts, Saratoga water, NATURE OF DYSPEPSIA.

CHAPTER XL SPECIAL CAUSES OF DYSPEPSIA. It is true, as a general proposition, that whatever impairs the health of the whole system or any part of it, conduces to the condition of defective nutrition termed dyspepsia. But there are many agents and influences which seem to derange the vital organism more prominently or more immediately in the primary nutritive function, which may properly be treated of as the spe- cial causes of dyspepsia. It is these agents and influences which are enumerated, more or less in detail in medical books, as causes of dyspepsia. The special causes of dyspepsia are more comprehensively and clearly stated by Dr. John Mason Good (" Study of Medi- cine,") than in the writings of any later author with which I am acquainted : " The common causes, whether confined to the stomach, or co-extensive with the associate viscera, may be contemplated under two heads, local and general. The local remote causes are, a too large indulgence in sedative and diluting substances ; as tea, coffee, and warm water, or similar liquids taken as a beverage ; or an equal indulgence in stimulant and acrid mate- rials, as ardent spirits, spices, acids, tobacco, whether smoked or chewed, snuffs, a daily habit of distending the stomach by hard eating or drinking ; or a rigid abstemiousness, and very protracted periods of fasting. The general remote causes are, an indolent or sedentary life, in which no exercise is afford- ed to the muscular fibres or mental faculties. Or, on the other hand, habitual exhaustion from intense study, not properly alternated with cheerful conversation ; becoming a prey to the Violent passions, and especially those of the depressing kind, SPECIAL CAUSES OF DYSPEPSIA. 87 as fear, grief, deep anxiety ; immoderate libidinous indulgence, and a life of too great muscular exertion. Perhaps the most common of this latter class of causes are, late hours, and the use of spirituous liquors." There is one prolific cause of indigestion, and of those mos' distressing complications, obstinate constipation, pile tumor. , prolapsus of the lower bowel, fistula in ano, and fissures in the rectum, which medical authors do not mention, although some of them allude to it as among the general causes of indigestion. I mean purgative or cathartic medicine, regular or irregular. Torpid or inactive bowels is so nearly a universal condition in civilized society, that purgative medicine of some kind is gene- rally regarded as necessary as is food or drink. And people generally regard them as among the most innocent, or at the most, the least injurious of the various classes of medicines. It is a disastrous mistake. Bad as liquor and tobacco are, purgatives are much worse. A majority of persons may take an ordinary drink or dose of rum, brandy, gin, or whisky, three times a day with less injury to the health, than are doses of jalap and cream of tartar, senna and salts, castor oil, or any of the multitudinous aperient, purgative, bilious, or anti-bilious pills that are swallowed by hundreds of tons annually. It is well known to physicians that the habitual employment of purgative medicines of any kind, however much it may relieve temporarily, never fails to aggravate constipation in the end. I have had patients to treat whose bowels, after being pilled for a few years, would not move without special attention, once a week. In one instance a patient came to me from Europe to be treated for constipation. He had taken cathar- tics regularly for a dozen years, and his bowels were so devital- ized that, during a fifteen days' passage across the Atlantic, his bowels did not move at all, nor did he experience the least indi- cation in that direction. Women suffer more than men of purgative medicines because their more sedentary habits seem to require larger doses or more frequent repetitions. The late Professor William Tully, M. D., of Yale College, said to his medical class that more injury was done by the 88 DYSPEPSIA. injudicious use of cathartics, by the regular profession, as a whole, than by all other classes of medicines. The late Professor Robley Dunglison, M. D. , in his work "Therapeutics and Materia Medica," denounces the prevalent employment of cathartics by physicians in no measured terms ; and he quotes (Vol. I. page 176,) the eminent Dr. Stokes, of London, with regard to their use in fevers, as follows : "A common practice has prevailed in these countries, and indeed, still exists to a very great extent, of making the patient take purgative medicine every day ; and this, I regret to say, is too often done even in cases where the surface of the small intestine presents extensive patches of ulceration. Now, I will ask you, can anything be so barbarous as this, or can it be ex- ceeded in folly or mischief by the grossest acts of quackery ? Here we have an organ in a state of high irritation, and exhib- iting a remarkable excitement of its circulation, and yet we proceed to apply stimulants to that organ, and to increase the existing irritation. Would it not be absurd, in a case of in- flammation of the knee or elbow-joint, to direct a patient to use constant exercise and motion ? Would it not be a very strange practice to apply irritants to a raw and excoriated sur- face ? Yet something equally absurd and equally mischievous, is done by those who employ violent purgatives in a case of inflammation of the digestive tube in fever. This has been a great blot in the history of British practice. Calomel and black bottle, and even jalap and aloes, and scammony, have been prescribed for patients laboring under severe and extensive dothinenteritis. Morbid stools are discharged, and the more morbid they are, the more calomel and purgatives does the physician give to change their character, and bring them back to the standard of health. I want words to express the horrible consequences. Too often have I seen fever patients brought into the hospital with diarrhoea, hypercatharsis, and inflamma- tion of the mucous membrane from the use of purgatives administered before their admission. Practitioners will not open their eyes. They give purgatives day by day, a very easy practice, and one for which there are plenty of precedents ; but SPECIAL CAUSES OF DYSPEPSIA. 8 9 it is fraught with most violent consequences. I will freely admit, that the disciples of the school of Broussais have gone too far in decrying the use of laxatives altogether. But if they have lost hundreds by this error, British practitioners have killed thousands by an opposite plan of treatment. In cases of fever where there is no decided symptom of gastro-enteric disease, there can be no objection to the use of laxatives, if required, but they should always be of the mildest description. You will gain nothing by violent purging in fever ; mild laxatives alone can be employed ; and where there is any sign of intestinal irrita- tion present, even these should be used with caution. There is one mode of opening the bowels, which you may always have recourse to with advantage in fever, viz., the use of enemata. There is not the slightest doubt that, occasionally, accumu- lations of fecal matter will take place, and tend to keep up irri- tation, but they should always be removed with the least pos- sible risk of producing bad consequences. To purge in fever when intestinal irritation is present is a practice opposed alike to theory and experience, and I have already stated that its results are most horrible." All the reasons which Dr. Stokes presents so forcibly against the employment of cathartic drugs in* fevers, applies with still greater emphasis against their employment in dyspepsia, for the reason that, in fevers, the points of irritation are more diffused throughout the system, whereas in dyspepsia they are more concentrated along the tract of the alimentary canal. The late Professor Charles A. Lee, M. D., in some editorial notes to Copland's Medical Dictionary, pages 385 and 386, makes a fearful and yet most truthful statement of the pills and other causes now in operation to extend and perpetuate dyspep- sia among the people of the United States. There is food for reflection in the following paragraphs : " Dyspepsia is, comparatively, a modern disease in our country, having been scarcely known until within the last thirty years (1846). Our ancestors, as stated by an accurate observer, were accustomed to much bodily exertion ; there were but few pleasure or wheel-carriages in the country ; both DO DYSPEPSIA. males and females generally rode on horseback ; professional men almost universally had farms, on which they labored more or less ; merchants were also frequently engaged in mechanical pursuits ; the habits of living were simple and frugal ; intoxi- cating liquors were seldom drunk ; religious excitements, so destructive to the health both of body and mind, were almost unknown ; regular and natural hours of sleeping and eating were observed ; and these circumstances proved highly propi- tious in securing the general enjoyment of bodily health and mental vigor.* These salutary habits, however, have been gradually exchanged for those of a more unnatural and injuri- ous tendency ; bodily labor, carried to the point of fatigue, is now deemed degrading, if not decidedly vulgar ; languishing in easy carriages has succeeded to equestrian habits and equita- tion ; professional men confine themselves to the legitimate business of their calling ; excitements of every kind, civil, political, religious, mesmeric, are the order of the day ; habits of luxurious living have become general ; alcoholic drinks are more extensively used than formerly, although a great improvement has taken place within the last few years ; the almost universal practice prevails of using tobacco in some form; habits of inactivity, tight-lacing, keeping late hours, &c, are gradually undermining the health of the female sex, and lay- ing the foundation of gastric affections ; and all these causes, with numerous others that might be named, are slowly deteri- orating the health of the community, and their effects are likely to become still more evident and distressing in the next and succeeding generations. " How fearfully the prediction has been realized, as any one may see in the skeleton forms, gaunt abdomens, caved-in chests, projecting shoulders, wan complexions, dyspeptic walk, and consumptive look of the fashionable young ladies and gentlemen who promenade the thoroughfares of our great cities. Of the pill business, Professor Lee says : " Another very prominent cause of the prevalence of indi- * "A Dissertation on Chronic Debility of the Stomach, by Benjamin Wolsey Dwight, in Memoirs of the Connecticut Academy of Arts and Sciences. New Haven, llxj." SPECIAL CAUSES OF DYSPEPSIA. 91 gestion in this country is the excessive use of cathartic medi- cine in the form of pills. Were we to give the amount of the latter annually swallowed in the United States, the statement would not be believed ; and yet we have it from good authority, namely, that of the manufacturer himself, that one establish- ment in the city (New York, ) turns out, by the aid of steam, no less than ten barrels per day, and this is by no means so extensive as some others of a similar kind. These pills, which are highly drastic, are used by immense numbers of people, not only in cases of actual illness, but in time of health, as prophylactic remedies. The consequences are easily predicted. In addition to this, great quantities of bitters are used, in which brandy, wine, or some alcoholic liquor forms the princi- pal ingredient ; and on the occurrence of the least feeling of discomfort, recourse is had to the panacea, till at length the powers of the stomach are exhausted, and derangements either functional or structural take place. We could wish that the epitaph of the Italian count could be placed so as to be seen by every man, woman, and child : ' / was well — wished to be better — took physic, and died.' " Much of this evil is doubtless owing to physicians, who have been too much in the habit of pouring down drugs empirically in every case of illness, slight or severe, in order to humor a popular notion that the materia medica must furnish a remedy for every disease, and a popular prejudice that want of success is a sure indication of poverty of resource on the part of the practitioner." A little figuring will give us a more realizing sense of the extent to which the people are pilled. Our population has doubled since Dr. Lee wrote the above, and pill-makers have multiplied ; and as there could not have been less than half-a- dozen establishments in a single one of our cities, manufactur- ing each ten barrels per day, the quantity now made daily can- not be less than one hundred barrels per day ; and then Phila- delphia does an extensive business in the same line, as do Boston and other cities. But, reckoning the pills turned out 9 2 DYSPEPSIA. in the city of New York alone, let us see how the mattel stands, Pills vs. People. A barrel of pills will weigh about as many pounds as a bar- rel of pork, and a pill of average size three and a half grains. From this data the expert in arithmetic may soon ascertain that the good people of this enlightened nation are provided with the bowel-moving agencies of fifteen billion nine hundred and ninety-one million, six hundred thousand individual pills annu- ally. But our statistics thus far represent only the irregular trade. If we add the pills orthodoxically prescribed, we may swell the amount to twenty billions — two billions of pills for each million of our population, or five hundred pills for every man, woman, and child. And yet our ciphering is not com- plete. Young children cannot swallow pills ; there are Homoeopathists who do not believe in them, and Hygienists who never take medicine of any kind ; hence a nice calculation may allow the actual pill-takers about one thousand a year each, averaging within a fraction of three pills per day. How long the human stomach and bowels can stand this pill-trade is, like the problem of the final consummation of all things, only a question of time. The fact that our people ' ' still live " under it, is a sufficient demonstration that " humanity %s tough." Such a treatment of our domestic animals would exterminate them in a single generation. In a late work on Indigestion, by Arthur Leared, M. D., extracts from which appear in the Popular Science Monthly for May, 1872, the following remarks are made in relation to the most prominent causes of dyspepsia : "At all stages of adult life, but particularly during its decline, the appetite is over-stimulated by condiments, and tempted to excess by culinary refinements. Dyspepsia is not the worst result of this. Gout, and still more serious mala- dies connected with an impure state of the blood, closely follow." "Two habits, smoking and taking snuff, require special notice as causes of dyspepsia. Excessive smoking produces si depressed condition of the system, and a great waste of SPECIAL CAUSES OF DYSPEPSIA. 93 saliva, if the habit of spitting is encouraged. I have met some severe cases of dyspepsia clearly resulting from these causes. Some individuals are unable to acquire the habit of smoking even moderately. Deadly paleness, nausea, vomiting, inter- mittent' of pulse, with great depression of the circulation, come on whenever it is attempted. But this incapacity is exceptional, and so universal is the desire for tobacco, that it seems as if some want of the system is supplied by its use." What is the ' ' excessive " use of tobacco, or any other poison ? One might as well talk of excessive lying, or excess- ive stealing, as though moderation in these habits might be judicious, or necessary ! Nor does the great number that have depraved their instincts and become addicted to tobacco- using, make the vice a virtue. As well might the general prevalence of gambling or prostitution, in any given locality (Wall Street, Five-Points), be adduced as the evidence that gambling, or prostitution supplied some want of the system. And, verily, it does. But it is the craving of a demoralized mental or a debauched physical nature. It seems quite impossible for a modern medical author to write anything about tobacco or alcohol without doing it with the "modern improvements'' of logic. He knows they are bad. He knows the people are very much addicted to them. He cannot stultify himself by saying they are not injurious. He cannot stultify his business by saying they are wholly evil, and that continually. And so he compromises by condemn- ing their excessive and commending their moderate employ- ment, leaving his readers to find out where moderation ends and excess begins — in the grog-shop, the gutter, or the drunk- ard's grave, if they can. Winslow's Soothing Syrup. Perhaps no single quack nostrum is doing more mischief in our country at this time, in deranging the digestive organs of infants, paralyzing their nerves, stupefying their intellects, and laying the foundation for dyspeptic miseries and mental 94 DYSPEPSIA. imbecilities in later life, than this pernicious opiate. The Druggists Circular says : "Mrs. Winslow's Soothing Syrup has several times been condemned in the columns of The Druggists' Circular, but we have not published the formula. The original recipe is kept secret, but the results of analysis have been made known. It has been shown that one ounce of the syrup contains one grain of morphia. If, then, Mrs. Winslow's instructions be followed, the dose for an infant three months old contains an equivalent of ten drops of laudanum, and this Mrs. Winslow recommends to be repeated every two hours ! The injury that may be done by the ignorant use of such a nostrum is hardly to be estimated ; and yet a calculation has been made that not less than fifteen million ounces of the syrup are annually sold in the United States ; in other words, that the children of this country are dosed every year with as many million grains of morphia !" CHAPTER XII. SYMPTOMS OE DYSPEPSIA. As already stated, the symptoms of dyspepsia are as numer- ous and as complicated as are morbid conditions and abnormal sensations. In number and severity they vary infinitely, some dyspeptics being able to attend to their ordinary business and duties, and only experiencing occasional pain or distress in the stomach or auxiliary digestive organs, while others are unable to do anything but dwell despondently on their miserable feel- ings, and are, indeed, as wretched as human nature can bear and live. The symptoms attending the more important phases of the disease have been explained in connection with the organs and structures to whose special functional disturbance they are more particularly referable, in the first part of this work. I SYMPTOMS OF DYSPEPSIA. 95 will only add the description of Dr. Good, whose admirable work, though not now a text-book in our medical colleges, is a vastly more useful work for the medical student or the non- professional reader, than any work on the Theory and Practice of Medicine that has appeared since. " Dyspepsia may be regarded as consisting of the combina- tion of several morbid conditions, irregularly intermixed ; sometimes one set of symptoms taking the lead, and some- times another ; with a peculiar tendency to costive bowels, and especially that species of costiveness dependent on a weakly temperament or a sedentary habit, and in which the discharged foeces, instead of being congestive and voluminous, are hard, slender, and often scybalous. Dyspepsia, therefore, in the language of Dr. Cullen, may be described as a want of appetite, a squeamishness, sometimes a vomiting, sudden and transient distentions of the stomach, eructations of various kinds, heart- burn, pains in the region of the stomach, and a bound belly. Yet none of these are universally present, and all of them seldom. So that, as already observed, the symptoms of car- dialgia, flatulence, and vomiting, with a few others, enter in irregular modifications into dyspepsia, as those of dyspepsia enter into hypochondriasis. ' ' There is also another complaint which frequently enters into the multiform combination of maladies, of which dyspep- sia is the general expression, and which has been rarely noticed by writers, although it is often a very troublesome symptom, and that is gravel. In treating of gravel, or lithia, as an idiopathic affection, we shall have to notice that one of its chief and most common causes is an excess of acidity in the prima vice ; and, as such excess is almost constantly to be found in dyspepsia, gravel must frequently attend or follow, and is even a necessary effect where there exists what has been called a calculous diathesis. And, for a like reason, where there is a podagric diathesis, gout, in some form or other, is a frequent concomitant/' 1 'In dyspepsia the debility is not often confined to the stomach, but extends to the intestinal canal, and the collati- 9 6 DYSPEPSIA. tious viscera, as the mesentery, the spleen, the pancreas, ie neck ; the attendant rubs the body over the sheet (not with it), the patient exercising himself at the same time by rubbing in front. Pail-Douche. — This means simply pouring water over the sheet and shoulders from a pail. Stream-Douche.- -A stream of water may be applied to the part or parts affected, by pouring from a pitcher or other convenient vessel, held as high as possible ; or a barrel or keg may be elevated for the purpose, having a tub of any desired size. The power will be proportional to the a nount of water in the reservoir. Towel or Sponge-Bath.— Rubbing the whole surface with a coarse, 13° DYSPEPSIA. wet towel or sponge, followed by a dry sheet or towel, constitutes this pro- cess. The Wet Girdle. — Three or four yards of crash toweling make a good one. One-half of it is wet and applied around the abdomen, followed by the dry half to cover it. It should be wetted as often as it becomes dry. The Chest -Wrapper. — This is made of crash, to fit the trunk like an under-shirt, from the neck to the lower ribs ; it is applied as wet as possible without dripping, and covered by a similar dry wrapper, made of Canton or light woolen flannel. It requires renewing two or three times a day . The Sweating-Pack. — To produce perspiration the patient is packed in the flannel blanket or other bedding, as mentioned in the Wet-Sheet Pack, omitting the wet sheet. Some perspire in less than an hour ; others re- quire several hours. This is the severest of water-cure processes, ar in fact, is very seldom called for. The Plunge- Bath.— This is employed but little, except at the Esta- blishments. Those who have conveniences will often find it one of the best processes. Any tub or box holding water enough to allow the whole body to be immersed, with the limbs extended, answers the purpose. A very good plunge can be made of a large cask cut in two near the middle. It is a useful precaution to wet the head before taking a bath. The Shower-Bath. — This needs no description. It is not frequently used in treatment, but is often very convenient. Those liable to a "rush of blood to the head," should not allow much of the shock of the stream upon the head. Feeble persons should never use this bath until prepared by other treatment. Fomentations. — These are employed for relaxing muscles, relieving spasms, griping, nervous headache, etc. Any cloths wet in hot water and applied as warm as can be borne, generally answer the purpose ; but flannel cloths dipped in hot water, and wrung nearly dry in another cloth or handkerchief, so as to steam the part moderately, are the most efficient sedatives. Injections. — These are warm or tepid, cool or cold. The former are used to quiet pain and produce free discharge ; the latter to check excessive evacuations and strengthen the bowels. For the former purpose ~ large quantity should be used ; and for the latter a small quantity. General Bathing Rules.— Never bathe soon after eating. The most powerful baths should be taken when the stomach is most empty. No full bath should be taken less than three hours after a full meal. Great heat or profuse perspiration are no objections to going into cold water, provided the respiration is not disturbed, and the patient is not greatly fatigued or BATHING. exhausted. The body should always be comfortably warm at the time of taking any cold bath. Exercise, friction, dry wrapping, or fire may be re- sorted to, according to circumstances. Very feeble persons should com- mence treatment with warm or tepid water, gradually lowering the tempe- rature. The temperature of baths should always be regulated by the temperature of the patient. Very feeble invalids should never take very hot nor very cold baths of the whole surface, although hot or cold applications may be made locally to relieve spasms or check discharges. Dyspeptics who are not emaciated and are not disposed to chilliness may take a tepid ablution — 70 to 8c degrees — each morning, and a hip bath each afternoon for ten minutes, at 75 to 85 degrees. For feebler persons the tepid ablution or wet rubbing sheet each other day is sufficient, with the hip-bath on the alternate day. Still feebler persons may take the tepid rubbing sheet one day, the dry rubbing sheet the second day, and the hip-bath the third day, and so on ; and il extremely feeble the wet rubbing sheet should only be employ- ed once a week, and the dry rubbing sheet on the other days. The dry rubbing sheet is practically an air-bath, and has never been sufficiently appreciated in or out of health institutions. Sun-baths are among, the best appliances in self-treatment, as most patients can manage them without assistance. All that is needed is a sunshiny place, in-doors or out, where the temperature is agreeable. The patient has only to expose the naked body to the sunlight and make gentle friction over the whole surface with dry towels, or a sheet, for five to ten min- utes. * For bathing purposes, as for drinking and cooking, there is a great difference between pure and hard water. Hard and impure water may be better than none, but the rule is, the purer the better. *3* DYSPEPSIA. CHAPTER XIX. CLOTHING. So far as the recovery of health is concerned, the dyspeptic has only to dress in the most comfortable manner possible to insure the best possible results. But fashion has so demoral- ized judgment, perverted taste, and enslaved the minds of our people that it seems necessary to say a good deal on this sub- ject, in addition to what has been said and illustrated in the first part of this work ; and as the young ladies all over our country are going to rum in droves because of the unwhole- some garments that they put on, a few more " lines upon lines and precepts upon precepts, ' may not be inappropriate, We should always keep in mind that clothing can never impart heat to the body ; it only retains the heat which the body imparts, which heat of the body is owing to the circulation. The better the conducting material of clothing the more readily the heat of the body passes through it ; and the more non- conducting the material the longer the heat is retained ; hence in warm weather, linen and cotton, and in cold weather woolen and fir, are best adapted to maintaining an equilibrium of bodily temperature. Says a writer in the Science of Health : " We can easily understand how a delicate woman, weighed down by a mass of heavy clothing that would fatigue a strong man, with all her phys- ' ical powers depressed and her circulation reduced to a low ebb, should shiver with cold, within the most abundant wrappings. Do not make the mistake of supposing that a heavy fabric is necessarily a warm one. It is a fact that a few folds of light fleecy material thrown loosely together are a much more efficient protection against cold than a double thickness, even, of some stuff four times its weight, and as compact as a board. Let wool and fur, both in their natural shape bad conductors of heat and therefore well calculated to preserve the natural warmth of the body, enter largely into the attire, and in as light a form as possible ; refuse positively to don a garment of any sort in any weather, whose shape and weight shall impede the movements or cause the least sensation of fatigue in wearing it, and above all avoid weighing down the hips with the multiplicity of skirts which are CLOTHING. 133 the abomination of the present age of dress ; give the shoulders their proper share of the weight of the clothing to sustain ; allow no uncomfortable restrictions to impede the free action of the organs of breathing and circu- lation, and you may bid farewell to pains in the back and shoulders, to headache, and to diificulty of breathing ; you will ride less and walk more, for walking will then be a pleasure, instead of an almost impossible task, as it is to a fashionably dressed woman now-a-days." The Washington Star newspaper makes the following re- port of a lecture recently delivered in the Congregational Church of that city, by Mrs. Chandler. It is certainly record without prejudice. Dr. B. VV. Richardson, of London, has demon- strated, by a series of careful and elaborate experiments, that all forms of alcoholic liquors are just the reverse of stimulants, so far as the whole force of the circulation, and the whole amount of animal temperature are con- cerned. Directly or indirectly they waste vital power, as every other poi- son does, whether the person who swallows it is sick or well. Hygienic physicians never administer stimulants m cases of debility, prostration, or u running down " after fevers, and that is one of the principal reasons why their patients so geneially recover.
