Chapter 26

For the mentally exhausted, the worried, the "nervous," and the distressed in mind, fish is not simply a food; it acts as physic. The brain is nourished by it, the "nerves"--to use the term in its popular sense--are "quieted"; the mind grows stronger, the temper less irritable, and the whole being healthier and happier when fish is substituted for butcher's meat....I find persons who are greatly excited, even to the extent of seeking to do violence to themselves or to those around them, who can not sleep, and who are in an agony of irritability, become composed and contented when fed almost exclusively on fish. In such cases I have withdrawn butter, milk, eggs, and all the varieties of warm-blooded animal food; and, carefully noting the weight and strength, I find no diminution of either, while fish is supplied in such quantities as fully to satisfy the appetite.--J. MORTIMER GRANVILLE, M.D., "_Fish as Food and Physic_."

COFFEE AND TEA (p. 170).--Besides the alkaloid _Caffeine_ which coffee contains, it also develops, in roasting, a volatile oil called Caffeone, to which is due its characteristic aroma. The main effects of coffee are due to both the caffeine and the caffeone, which are antagonistic, though not contemporaneous, in action. The volatile oil reduces arterial tension, allows a brisker flow of blood, and so increases the rapidity of the heart's action. It also acts upon the brain, and intellectual faculties in general; keeps one awake, and his mind clear. Caffeine, on the other hand, like digitalis, produces a high arterial tension, and slows the heart beat. It exerts its chief effect upon the spinal cord, to which, like strychnia, it is an excitant. The shaking hand of the inveterate coffee drinker is caused by caffeine. Thus a cup of coffee produces on the drinker a double effect,--of the oil and the alkaloid; the former sooner and transient, the latter later and lasting....Coffee is not in itself nutritious to any marked degree; but it saves food, and also maintains life, by its exhilarating effect upon the nervous system. It is an excellent antidote to opium, producing the wakefulness that antagonizes the narcotic sleep of the drug; is now and then curative of sick headache, and is one of the standard remedies for certain forms of nausea.

To the chemist, _Tea_ is much the same thing as coffee. It contains considerably more tannin, a volatile oil, and an alkaloid (theine) indistinguishable from caffeine. That the injurious effects of overdoses are due as much to the volatile oil as to the alkaloid, is shown by the fact that tea packers are made ill by long breathing of air filled with it, and that tea tasters in China, who avoid swallowing the infusion, can endure their trade but a few years, and leave the country with shattered nerves.

Probably every one numbers among his friends women who are actual slaves of the tea habit, and who would find tea as hard to forsake as men find tobacco. It is not unlikely that the functional cardiac disorder, often spoken of as the "tobacco heart," due to nervous derangement, and accompanied by palpitation and pain in the cardiac region, is more often due to tea than tobacco. In fact, the disorders induced by excessive tea drinking have been grasped as a special disease, to which has been given the name of _Theism_. This includes a train of symptoms, usually progressive, loss of appetite, pain after meals, headache, constipation, palpitation, cardiac distress, hysterical manifestations, dizziness, and paresis.--DR. MAURICE D. CLARKE, _Popular Science News_.

Tea drinkers, as a rule, express doubts as regards the correctness of alleged poisonous properties of tea. Numerous instances of individuals of this class have been noticed who were themselves suffering from tea poisoning. Their nerves were in a deplorably abnormal condition, the heart and brain were functionally disturbed, and the sleep less in quantity and less refreshing than it should be....One's opinion of the physical disturbances which may be caused by rum, tobacco, or tea, are not worth much, when the opinion comes from a victim of the excessive use of these agents.

The tannin found in tea does not differ from that found in oak and other barks which the tanners use to convert the raw hides of animals into leather. It is a powerful astringent, which accounts for some of the peculiar physical evils to which confirmed tea drinkers are subject.

_Theine_ does not differ essentially from _Cocaine_ (see p. 223). They both produce exaltation of the nervous system and increased powers of physical endurance. The brain is largely influenced in its functions, and long periods of wakefulness are induced. Continued use of strong infusions of either coca or tea result in great disturbance of nervous centers and functional offices, and either will produce fatal results by persistent use of inordinate quantities.

A cup of tea as served at tea tables contains usually only a trace of the alkaloidal principle, but infinitesimal quantities are capable of exerting baneful effects upon some tea drinkers....Poisons act in a variety of ways, some slowly, and without producing pain; others act violently, and with speedy, fatal results. Inasmuch as we do not observe a very large number of clearly proved cases of acute poisoning by tea, we must conclude that it is characteristically a slow poison, and also that its influence is unlike in different individuals....Four or six cups of tea, however, taken during each twenty-four hours, will in time produce tea poisoning, and greater or less evil effects.

Tea is well enough, when its use is kept under absolute, intelligent control; but if it becomes master in any case, then it must be promptly abandoned, for danger attends the intemperate tea drinker every hour of his life. Those advanced in life crave its stimulating effects, and it is well for them to use it in moderation; but the young should abstain from it entirely.--_Abridged from "Tea Poisoning," by_ DR. NICHOLS, _in Popular Science News, December, 1887_.

CAUSES AND EFFECTS OF INDIGESTION (p. l72).--When a light breakfast is eaten, a solid meal is requisite in the middle of the day. If the digestive organs are left too long unemployed, they secrete an excess of mucus, which greatly interferes with their normal functions. One meal has a direct influence on the next; and a poor breakfast leaves the stomach over-active for dinner. This is the secret of much excess in eating. The point to bear in mind is that not to eat a sufficiency at one meal makes you too hungry for the next; and that when you are too hungry, you are apt to overload the stomach, and to give the gastric juices more to do than they have the power to perform.

To eat too often, and to eat irregularly, are other sources of indigestion. People who dine at uncertain hours, and eat one meal too quickly on the last, must expect the stomach to retaliate in the long run. A very fruitful cause of dyspepsia is imperfect mastication. We remember one old gentleman who used always to warn young people on this point by saying: "Remember you have no teeth in your stomach." Nervous people nearly always eat fast, and as nearly always are the victims of nervous irritability, produced by dyspepsia....To sit much in a stooping posture interferes with the stomach's action. Well-marked dyspepsia has been traced to sitting immediately after dinner in a low armchair, so that the body was curved forward, and the stomach compressed....

The skin, core, and kernels of fruit should be avoided. Some people are not able to digest raw apples; and dyspepsia has been sometimes greatly aggravated by eating pears. The latter fruit, in its ripest state, contains an abundance of gritty material, which, as it can not be separated in the mouth, on being swallowed irritates the mucous membrane....

Of food itself, bear in mind that hot meat is more digestible than cold; the flesh of full-grown animals than that of young ones; that land birds are more digestible than waterfowl; wild animals than domestic ones; and that in game, newly killed birds are easier of digestion than those which have been kept a long time.--_Hints to Dyspeptics, Chambers's Journal_.

HOW FOOD DEVELOPS ENERGY (p. 173).--It may appear strange that the small amount of food we eat should suffice to carry our large and bulky bodies through all the varied movement of the day. But this difficulty disappears at once, when we recollect how large an amount of dormant energy can be laid by in a very small piece of matter. A lump of coal no bigger than one's fist, if judiciously employed, will suffice to keep a small toy engine at work for a considerable time. Now, our food is matter containing large amounts of dormant energy, and our bodies are engines so constructed as to utilize all the energy to the best advantage. A single gramme of beef fat if completely burned (that is, if every atom unites with oxygen), is capable of developing more than 9,000 heat units; and each heat unit, if employed to perform mechanical work, is capable of lifting a weight of one gramme to a height of 424 meters; or, what comes to the same thing, 424 grammes to a height of one meter. Accordingly, the energy contained in one gramme of beef, and the oxygen with which it unites, would be sufficient to raise the little bit of fat itself to a height of 3,816 kilometers, or almost as high as the distance from London to New York.-- GRANT ALLEN _in "Why do we Eat our Dinner_?"

_Danger of Too High Pressure_.--A prudent fire engineer, when his water hose is old and weak, would not try to force as much water as he could into it. No; to prevent a rupture he would work it at a low pressure. But men seldom think of carrying out the same simple mechanical principle when there is reason to believe that the vessels of the brain are getting weak and brittle. They eat and drink just as much as they feel inclined to, and sometimes a little more. With a good digestion, nearly all they consume is converted into blood, to the yet further distention of vessels already over-distended. This high-pressure style of living produces high-pressure results. Its effects were painfully illustrated by the death of Charles Dickens. The brain work he performed was immense; he lived generously, taking his wine as he did his meat, with a liberal hand. He disregarded the signs of structural decay, forcing his reluctant brain to do what it had once done with spontaneous ease, until all at once, under a greater tension than ordinary, a weak vessel gave way, flooding the brain with blood.--J. R. BLACK, M.D., _in "Apoplexy," Popular Science Monthly, April, 1875_.

_Evils of Gluttony_.--"Is it not strange," says Dr. Hunt, "how people, even the most considerate, will trifle with their stomachs? Many a person seems to prefer taking medicine to avoiding it by a proper regulation of the appetite. You may stuff the stomach to the full, year after year, but as sure as effects follow causes, so sure will you reap the accumulating penalty." A physician of extensive practice declares that he has never lived through a Christmas or Thanksgiving without frequently being consulted for ailments produced by excessive eating. He says: "It would seem as if multitudes thought they had a gluttonous license once a year, and that the most appropriate method of expressing gratitude, was by stuffing the stomach. Excessive eating produces scrofula. Surfeiting among children results in mental stupidity and unmanageable temper....I am acquainted with a family, in which about the average amount of stuffing is indulged. To my expostulations, the mother has replied: "I may not be able to give my children as much education as some folks, and I may not be able to give them any property, but as long as we can get it, they shall have what they want to eat. I have spoken of their black teeth, bad breath, eruptions, and frequent sickness. "Yes," she has replied, "I know all that, but would you have me stop them before their appetites are half satisfied, and tell them, 'there, that is all you can have'? No; as long as I can get it, my children shall have enough to eat; it never shall be said that I have starved them." This indulgence of children to the full extent of their undiscriminating appetites is extreme folly and genuine unkindness. Pampered with a variety of dishes, they eat enormously, which engenders a craving for another large meal, and so on--their youthful and elastic constitutions enabling them to bear the excess without immediate serious injury. Let them be confined to one or two plain dishes at a meal, and the quantity be determined for them; it will then be found that a growing child does not need to be stuffed, and that his appetite will soon become reasonable; and if the food be plain, and mostly or entirely vegetable, it will soon be observed that the child's teeth are whiter, its breath sweeter, its skin clearer, its tongue cleaner, its eyes brighter, its sleep quieter, its brains sharper, and its temper more amiable. There are few changes in the management of children which would prove so beneficial as that from the present mode of cramming with a multitude of rich foods, to a plain vegetable diet, eaten in regular and moderate quantities.--DIO LEWIS, _in Weak Lungs, and How to Make them Strong_.

REGULAR PHYSICAL HABITS (p. 177).--Constipation lies at the root of a host of chronic ailments, which seem especially to beset American women. Impaired blood, nervous excitability, sick headaches, mental depression, sleeplessness, and a long train of untold sufferings may be directly traced to this physical sin. We say _sin_, for in the large majority of instances this habit may be prevented; or, if already formed, may, by proper attention, be cured. The principal causes which lead to this deplorable state of the system are:

1. Errors in Food.

2. Errors in Exercise.

3. Inattention to Nature's laws.

_Errors in Food_ have much to do with the evil in question. Our diet is, in general, too concentrated. We indulge ourselves with animal food two or three times a day, accompanying it with spices, condiments, greasy gravies, fine wheat bread, and a sparse amount of vegetables. We wind up our dinners with rich and heavy pastry, and our luncheons or our suppers with sugared sweetmeats and that indigestible compound often offered under the name of cake. A few cups of strong tea intensify the error. Coffee has a less astringent effect, and therefore can not be so severely arraigned for this particular consequence. When we think what delicious meals can be enjoyed from any of the cereals, well cooked, and taken with milk or cream, bread from unbolted flour, plenty of unsugared fruit, and pure rain or spring water, filtered and cooled or taken hot, with or without milk, we wonder that so many people consent day after day to use greasy pork, fried steaks, fried potatoes, hot biscuit, and in many cases poorly made coffee and tea. These are the people who make up the grand army of sallow- faced sufferers upon which the venders of patent pills and nauseous compounds thrive.

A wise mother will not allow mere culinary convenience to take precedence of the requirements of health. She will study the peculiar physical needs of each one of her children, that she may provide for each the food best suited to his or her constitution. This is not a difficult matter. "Water, not only by itself, but in some of its combinations," says Dr. Oswald, "is an effective aperient; in watermelons, and whey, for instance, but still more in conjunction with a dish of peas, or beans. No constipation can long withstand the suasion of a dose of pea soup, or baked beans, flavored with a modicum of brown butter, and glorified with a cup of cold spring water. Moreover, the aperient effect thus produced is not followed by an astringent reaction, as in the case of drugs,--the cure, once effected, is permanent."

_Errors in Exercise_ may lie in two directions, and overexertion, viz., exercise carried to the point of nervous exhaustion, is as mischievous in its effect as is the other extreme. A too long walk, for instance, may cause the very evil it is intended to cure.

As a rule, however, sedentary habits are chargeable with the greater share of influence in this unhappy state of the system. Light gymnastics within doors, a brisk walk or horseback ride without, both taken in garments suspended from the shoulders, and devoid of all constriction so that the abdominal viscera can partake in the general movement of the body, are advisable. For invalids or those incapacitated for active exercise, friction or massage treatment daily, including a vigorous kneading of the abdomen, or a relaxation of the entire muscles of the body with especial thought directed to the desired result, are often of great service.

_Inattention to Physical Laws_ is perhaps the prime culprit. Nature always inclines to regularity, and when we do not respect her dictates, we invite the retribution which, sooner or later, she invariably inflicts. The elimination of waste from the system is an imperative necessity, and whenever it is thwarted, evil must and will follow. Aside from the avoidance of positive discomforts, suffering, and disease, there is the not unimportant consideration of bodily elasticity and a fine complexion. Let every young woman who would possess and retain a fair, delicate complexion, remember that the most important factor in its formation and retention is a clean system.

Proper diet, plenty of fruits, plenty of wholesome drink, enough exercise to send the blood pleasurably bounding through the veins, followed up and enforced by prompt recognition of the immutable laws of Health in this as well as all other organic functions, will soon work a reform that could not be so successfully effected by all the drugs in Christendom.--E. B. S.

THE NERVOUS SYSTEM.

EFFECT OF VIOLENT PASSIONS UPON HEALTH (p. 202).--The man who is given to outbursts of anger is sure to experience a rapid change of the physical organs, in case he does not die in a fit of rage.

Death under such circumstances is of frequent occurrence. Sylla, Valentinian, Nerva, Wenceslas, and Isabeau of Bavaria, all died in consequence of an access of passion. The medical annals of our own time recount many instances of fatal effects following the violent brain disturbance caused by anger. The symptoms usually are pulmonary and cerebral congestions. Still such fatal accidents as these are exceptional; as a rule, the passions of hate and anger deteriorate the constitution by slow, but sure degrees.

How, then, do we explain those morbid phenomena which have their origin in misplaced affection, in disappointed ambition, in hatred, or in anger, and which culminate either in serious chronic maladies, or in death or suicide? They all seem to start from an impairment of the cerebro-spinal centers. The continual excitation of these by ever-present emotions determines a paralysis of the central nerve substance, and thus affects its connections with the nerves extending out to the various organs. These nerves next degenerate by degrees, and soon the great functions are compromised. The heart and the lungs cease to act with their normal rhythm, the circulation grows irregular and languishing. Appetite disappears, the amount of carbonic acid exhaled decreases, and the hair grows white, owing to the interruption of the pigmentary secretion. This general disturbance in nutrition and secretion is attended with a fall of the body's temperature and anæmia. The flesh dries up and the organism becomes less and less capable of resisting morbific influences. At the same time, in consequence of the reaction of all these disturbances on the brain, the psychic faculties become dull or perverted, and the patient falls into a decline more or less complicated and aggravated by grave symptoms. Under these conditions he dies or makes away with himself.

Two organs, the stomach and the liver, are often affected in a peculiar and characteristic way in the course of this pathological evolution. The modifications produced in the innervation, under the influence of cephalic excitement, cause a disturbance of the blood circulation in the liver. This disturbance is of such a nature that the bile, now secreted in larger quantity, is resorbed into the blood instead of passing into the biliary vesicle. Then appears what we call jaundice. The skin becomes pale, then yellow, owing to the presence in the blood of the coloring matter of the bile. This change in the liver is usually developed slowly: sometimes, however, jaundice makes its appearance suddenly. Villeneuve mentions the case of two youths who brought a discussion to an end by grasping their swords; suddenly one of them turned yellow, and the other, alarmed at this transformation, dropped his weapon. The same author speaks of a priest who became jaundiced on seeing a mad dog jump at him. Whatever may be said of these cases, we must reckon painful affections of the soul among the efficient causes of chronic diseases of the liver.

The digestion, says the author of a work published some years ago, is completely subjected to the influence of the moral and intellectual state. When the brain is wearied by the passions, appetite and digestion are almost gone....There is nowhere perfect health, save when the passions are well regulated, harmonized, and equipoised. Moral temperance is as indispensable to a calm and tranquil life as physiological temperance....If it is your desire that your circulatory, respiratory, and digestive functions should be discharged properly, normally, if you want your appetite to be good, your sleep sound, your humor equable, avoid all emotions that are overstrong, all pleasures that are too intense, and meet the inevitable sorrows and the cruel agonies of life with a firm and resigned soul. Ever have some occupation to employ and divert your mind, and to make it proof against the temptations of want or of desire. Thus will you attain the term of life without overmuch disquiet and affliction.--FERNAND PAPILLON, _in the Revue des Deux Mondes_.

BRAIN WORK, OVERWORK, AND WORRY (p. 205).--_Overstimulation of the Brain in Childhood_.--Most civilized communities have enacted laws against the employment of children in severe physical labor. This is well enough, for the muscles of young persons are tender and weak, and not, therefore, adapted to the work to which cupidity or ignorance would otherwise subject them. But no such fostering care does the State take of the brains of the young. There are no laws to prevent the undeveloped nervous system being overtasked and brought to disease, or even absolute destruction. Every physician sees cases of the kind, and wonders how parents of intelligence can be so blind to the welfare of their offspring as to force, or even to allow, their brains to be worked to a degree that, in many cases, results in idiocy or death. Only a few months ago I saw for the first time a boy of five years of age, with a large head, a prominent forehead, and all the other signs of mental precocity. He had read the first volume of Bryant's "History of the United States," and was preparing to tackle the other volumes! He read the magazines of the day with as much interest as did his father, and conversed with equal facility on the politics of the period. But a few weeks before I saw him he had begun to walk in his sleep, then chorea had made its appearance, and on the day before he was brought to me he had had a well-marked epileptic paroxysm. Already his mind is weakened --perhaps permanently so. Such cases are not isolated ones. They are continually occurring.
