_Danger in Bathing when Overheated_.--It is unwise to bathe when copious perspiration has continued for an hour or more, unless the heat of the weather be excessive, or the sweating has been induced by loading with clothes, rather than by exertion. When much perspiration has been produced by muscular exercise, it is unsafe to bathe, because the body is so fatigued and exhausted, that the reaction can not be insured, and the effect may be to congest the internal organs, and notably the nerve centers. The latter gives cramp. If the weather be chilly, or there be a cold wind, so that the body may be rapidly cooled at the surface while undressing, it is not safe to bathe. Under such conditions, the further chill of immersion in cold water will take place at the precise moment at which the reaction consequent upon the chill of exposure by undressing ought to take place, and this second chill will not only delay or altogether prevent the reaction, but will convert the bath from a mere stimulant to a depressant, ending in the abstraction of a large amount of animal heat and congestion of the internal organs and nerve centers. The aim must be to avoid two chills, and to make sure that the body is in such a condition as to secure a quick reaction on emerging from the water, without relying too much on the possible effect of friction by rubbing. The actual temperature of the water does not affect the question so much as its relative temperature in comparison with that of the surrounding air. It ought to be much lower than that of the air. These maxims receive a striking reenforcement from the case of a young soldier who a few days ago plunged into the river near Manchester, England, after having heated himself by rowing. He was immediately taken with cramps, and was drowned. When taken out, his body was found "twisted," and the vessels of his head showed every evidence of congestion.--_Popular Science Monthly, September, 1883_.

_Bather's Cramp_.--Cramp is a painful and tonic muscular spasm. It may occur in any part of the body, but it is especially apt to take place in the lower extremities, and in its milder forms it is limited to a single muscle. The pain is severe, and the contracted muscles are hard and exquisitely tender. In a few minutes the spasm and pain cease, leaving a local sensation of fatigue and soreness. When cramp affects only one extremity, no swimmer or bather endowed with average presence of mind need drown; but when cramp seizes the whole of the voluntary muscular system, as it probably does in the worst cases, nothing in the absence of prompt and efficient extraneous assistance can save the individual from drowning. [Footnote: Even this is often unavailable, as in the case of the Cornell University postgraduate drowned in Hall Creek, Ithaca, June 10, 1888. In this instance the day was hot and oppressive, and the victim sank soon after entering the water. "His companions at once hastened to his relief, and recovered his body in a few minutes. Professor Wilder, of the University, was hurriedly summoned, and every possible method was resorted to in order to induce respiration, but the vital spark had fled. An attack of cramps is supposed to have been the cause of drowning."] Prolongation of muscular exertion, as in continued swimming, and forcible and sudden muscular exertion, as in swimming with very vigorous and rapid strokes, are efficient and frequent causes of cramp. These muscular conditions, however, usually give rise only to the slighter and more localized forms. Serious cramp is a peril which menaces most persons with highly developed muscles. Its most powerful and most avoidable cause is the sudden immersion of the body, when its surface is highly heated, in water of a relatively low temperature.--_Popular Science News._

_Protection of the Ear in Sea Bathing_.--Special attention should be paid by bathers to the exclusion of salt water from the mouth and ears. Many cases of inflammation of the ear, followed by severe and lasting trouble, even to deafness, are chargeable to the neglect of this precaution. Incoming waves should never be received in the face or the ears, and the sea water which enters the ears when floating or diving should be wiped out by soft cotton; indeed, the best plan is to plug the openings of the ears with cotton, which is to be kept there during the bath.--_Science_.

_How one who Knows not how to Swim can Escape Drowning_.--It is well for every one to learn the art of swimming, yet it is a knowledge possessed by comparatively few people. Mr. Henry MacCormac, a writer in _Nature_, gives some common sense instructions that, if heeded, may be of great service to those persons who, not knowing how to swim, may find themselves accidentally precipitated into the water. We condense from his article, adding some directions, as follows:

In order to escape drowning, it is necessary only to do as the brute does, namely, to walk or tread the water. The brute has no advantage over man in regard to his relative weight, and yet the man perishes while the brute survives. The ignorance of so simple a possibility as that of treading water strikes me as one of the most singular things in the history of man. Perhaps something is to be ascribed to the vague meaning which is attached to the word _Swim_. The dog is wholly incapable of _swimming_ as a man swims, but nothing is more certain than that a man, without previous training or instruction, can swim just as a dog swims, and that by so doing without fear or hesitancy, he will be just as safe as is the dog. The brute thus circumstanced continues to go on all fours, as if he were on land, _keeping his head well out of the water_. So with the man who wishes to save his life and can not otherwise swim. He must strike alternately, with hand and foot,--_one, two, one, two,_--without hurry or precipitation, exactly as the brute does. Whether he be provided with paw or hoof, the beast swims with perfect ease and buoyancy. So, too, can the human being, if he will, with the further immense advantage of having a paddle-formed hand, and of being able, when tired, to rest himself by floating, an act of which the animal has no conception. The printed direction should be pasted up in all boathouses, on every boat, at every bathing place, and in every school: _Tread water when you find yourself out of your depth_. This is all that need be said, unless, indeed, we add: _Float when you are tired_. To float, one needs only to turn upon his back, keeping--as always when in the water--the mouth and chin well up and the lungs full of air.--Every one of us, of whatever age and however encumbered with clothing, may tread water, even in a breaking sea, with as much facility as a fourfooted animal. The position of the water treader is, really, very much safer and better than the sprawling attitude of the ordinary swimmer. But the chief advantage lies in the fact that we can tread water without preliminary teaching, whereas, though we recommend all to learn how to swim, it involves time and pains, entails considerable fatigue, and is, after all, very seldom adequately acquired.

HINTS ON CLOTHING (p. 67).--_Advantages of Woolen Fabrics_.--Wool is more irritating than cotton, on account of the stiffness of the hairs with which it bristles; but the excitation it produces becomes a therapeutic means whenever the skin needs a stimulant.

The use of wool is particularly desirable in some countries and under some conditions of life. Professor Brocchi, a writer well known for his investigations in malaria, attributes the good health and vigor of the ancient Romans to their habit of wearing coarse woolen clothes; when they began to disuse them, and to wear lighter goods and silks, they became less vigorous and less able to resist the morbid influence of bad air. It was at about the time the women began to dress in notably fine tissues that the insalubrity of the Roman air began first to be complained of. "In the English army and navy," says Dr. Balestra, "the soldiers of garrisons in unhealthy places are obliged constantly to wear wool next to the skin, and to cover themselves with sufficient clothing, for protection against paludine fevers, dysentery, cholera, and other diseases." According to Patissier, similar measures have been found effectual in preserving the health of workmen employed on dikes, canals, and ditches, in marshy lands; while, previous to the employment of these precautions, mortality from fevers was considerable among them.

Dr. Balestra has proved by direct experiments in marshy regions that thick and hairy woolen garments arrest in their down a portion of the germs borne in by the air, which thus reaches the skin filtered and purified. The ancient Romans wore ample over-garments over their tunics, and never put them away. It is no less important to be well covered during the night; and precautions of this kind should be recommended to all who live in a swampy country. We are sometimes astonished when we see the natives of particularly warm countries enveloped in woolen, as the Arab in his burnoose, or the Spanish peasant in his tobacco-colored cloak. Such materials protect both against the rays of the sun and against the coolness of the night, and are excellent regulators of heat. It is dangerously imprudent to travel in southern countries without provision of warm clothing.--_Revue des Deux Mondes_.

_Weight is not Warmth_.--While speaking of the warmth of clothing for inclement weather, it would be incorrect not to speak of weight in relation to warmth. Many persons mistake weight for warmth, and thus feeble people are actually borne down and weakened by the excess of heavy clothing which is piled on them. Good woolen or fur fabrics retain the heat, and yet are light. When fabrics intended for sustaining warmth are made up of cotton, the mistake of accepting weight for warmth is made. The same errors are often made in respect to bed coverings, and with the same results.

_Poisonously Dyed Clothing_.--The introduction of wearing apparel, socks, stockings, and flannels which have been made, by new processes of dyeing, to assume a rich red or yellow color, has led to a local disease of the skin, attended, in rare cases, with slight constitutional symptoms. This disease is due to the dyestuffs. The chief poisonous dyes are the red and yellow coralline, substances derived from that series of chemical bodies which have been obtained of late years from coal tar, and commonly known as the aniline series.

The coloring principle is extremely active as a local poison. It induces on the skin a reddish, slightly raised eruption of minute round pimples which stud the reddened surface, and which, if the irritation be severe and long-continued, pass into vesicles discharging a thin watery ichor and producing a superficial sore. The disease is readily curable if the cause of it be removed, and, as a general rule, it is purely local in character. I have, however, once seen it pass beyond the local stage. A young gentleman consulted me for what he considered was a rapidly developed attack of erysipelas on the chest and back. He was, indeed, covered with an intensely red rash, and he was affected with nervous symptoms, with faintness and depression of pulse, of a singular and severe kind. I traced both the local eruption and the general malady to the effect of the organic dye in a red woolen chest and back "comforter." On removing the "comforter" all the symptoms ceased. Similar and even fatal cases have been known from the wearing of highly colored hose.

_Uncleanliness of Dress_.--Uncleanly attire creates conditions favorable to disease. Clothing worn too long at a time becomes saturated with the excretions and exhalations of the body, and, by preventing the free transpiration from the surface of the skin, induces oppression of the physical powers and mental inactivity. This observation will be accepted by most persons as true in respect to underclothing; it is equally true in regard to those outer garments which are often worn, unremittingly, until the linings, torn and soiled, are unfit altogether for contact with the cleaner garments beneath them. Health will not be clothed in dirty raiment. They who wear such raiment suffer from trains of minor complaints; from oppression, dullness, headache, nausea, which, though trifling in themselves, taken one by one, when put together greatly reduce that standard of perfect health by which the value of life is correctly and effectively maintained.--RICHARDSON.

RESPIRATION.

THE VOCAL ORGANS.--_Musical Tones in Speaking_ (p. 76).--Voice is divided into singing and speaking voice. One differs from the other almost as much as noises do from musical sounds. In speaking, the sounds are too short to be easily appreciable, and are not separated by fixed and regular intervals, like those of singing; they are linked together, generally by insensible transitions; they are not united by the fixed relations of the gamut, and can only be noted with difficulty. That it is the short duration of speaking sounds which distinguished them from those of singing, is proved by this, that if we prolong the intonation of a syllable, or utter it like a note, the musical sound becomes evident. So, if we pronounce all the syllables of a phrase in the same tone, the speaking voice closely resembles psalm singing. Every one must have noticed this in hearing schoolboys recite or read in a monotone, and the analogy is complete when the last two or three syllables are pronounced in a different tone. Spoken voice is, moreover, always a chant more or less marked, according to the individual and the sentiment which the words express....It is related of Gretry, that he amused himself by noting as exactly as possible the "Bonjour, monsieur!" (Good day, sir!) of the persons who visited him; and these words expressed by their intonation, in fact, the most opposite sentiments, in spite of the constant identity of the literal sense.

_Speech without a Tongue_.--De Jussieu relates that he saw a girl fifteen years old, in Lisbon, who was born without a tongue, and yet who spoke so distinctly as not to excite in the minds of those who listened to her the least suspicion of the absence of that organ.

The Transactions of the Royal Society of London (1742) contain an account of a woman who had not the slightest vestige of a tongue, but who could, notwithstanding, drink, eat, and speak as well and as distinctly as any one, and even articulate the words in singing. Other instances have been known where individuals, after losing a portion of the tongue by accident or disease, have again been able to speak after a longer or shorter period.--LE PILEUR.

_Stimulants and the Voice_.--"The Drinker's Throat" is a recognized pathological condition, and the Germans have a popular phrase, "He drinks his throat away." Isambert has pointed out the directly local irritant effect of both alcohol and tobacco on the throat, and also the mode by which these agents, on absorption into the system, re-manifest their presence by predisposing to local pharyngeal inflammations. Dr. Krishaber affirms: "It is generally admitted that alcoholic beverages and tobacco irritate the mucous membrane of the throat, directly affect the voice, and leave on it ineffaceable traces. We hold with equal certainty that tea and coffee, although not directly affecting the voice, do so indirectly by acting on the nervous system, and through it the vocal organs, as well as by, some general nervous derangement not very pronounced, but great enough to deprive the singer of the full powers and capabilities of his voice."

Dr. Mackenzie says: "The influence of the general health upon the voice is very marked. Alcohol and tobacco should never be used. The hoarse tones of the confirmed votary of Bacchus are due to chronic inflammation of the lining membrane of the larynx; the originally smooth surface being roughened and thickened by the irritation of alcohol, the vocal cords have less freedom of movement, and their vibrations are blurred, or rather muffled, by the unevenness of their contiguous edges."

A young American lady of marked musical gifts once asked Adelina Patti's advice upon preparing for the stage. She found the great singer wrapped in furs, although the weather was not severe. After hearing her visitor, Patti replied: "Are you willing to give up _everything_ for your art? If you wish to succeed, you must learn to eat moderately, take no stimulants--not even tea or coffee--keep as regular hours as possible consistent with your public appearance, and even deny yourself the luxury of friends. When you hear of a great vocalist giving extravagant wine suppers, you may be sure that the singer herself takes nothing. To be a successful _artiste_ you must be married, soul and body, to your art." Like the young man to whom Christ spake, the young woman "went away sorrowful," and, balancing the terms, concluded to forego the contest.

ABDOMINAL RESPIRATION (p. 8l).--It has often been stated that the respiration of woman differs from that of man, in being limited almost entirely to the chest. In order to investigate this subject scientifically, Dr. Mays, of Philadelphia, devised an ingenious instrument for examining the respiration of the native Indian girls in the Lincoln Institution. The girls had not yet been subjected to the restrictions of civilized dress. He says:

"In all, I examined the movements of eighty-two chests, and in each case took an abdominal and a costal tracing. The girls were partly pure and partly mixed with white blood, and their ages ranged from between ten and twenty years. Thus there were thirty-three full-blooded Indians, five one fourth, thirty-five one half, and two three fourths white. _Seventy- five_ showed a _decided abdominal_ type of breathing, three a costal type, and three in which both were about even. _Those who showed the costal type, or a divergence from the abdominal type, came from the more civilized tribes_, like the Mohawks and Chippewas, and were either _one half_ or _three fourths white_; while in _no single instance_ did a full-blooded Indian girl possess this type of breathing.

"From these observations it obviously follows that, so far as the Indian is concerned, the abdominal is the original type of respiration in both male and female, and that the costal type in the civilized female is developed through the constricting influence of dress around the abdomen. While these tracings were taken an incident occurred which demonstrated that abdominal constriction could modify the movements of the thorax during respiration. At my first visit to the institution I obtained an exceptional costal type of respiration from a full-blooded Indian girl. At my next visit I concluded to repeat this observation, and found that, contrary to my instructions concerning loose clothing, etc., this girl at my first visit had worn three tight belts around her abdomen. After these were removed she gave the abdominal type of breathing, which is characteristic of nearly all the Indian girls."

To us these facts are invaluable. It shows the faulty construction of modern female dress, which restricts the motion of abdominal respiration. It explains why, as experience has taught us, it is necessary to restore this abdominal rhythm, by proper movements, in order permanently to cure the affections of the lower portion of the trunk. It demonstrates conclusively that woman's dress, to be injurious, needs only to interfere with the proper motion of respiration, even though it exercises not the slightest compression.--_Health Record_.

THE GERM THEORY OF DISEASE (p. 86).--_What are Disease Germs?_-- Microscopical investigation has revealed throughout Nature, in the air, in water--especially when it contains organic matter, and even within the bodies of persons and animals, myriads of infinitesimal active organisms which live, multiply, and die in endless succession. These have been named _bacteria_ (bacterium, a rod, so called from the general rod shape first observed), and also _microbes_ (microbe, a small living object). Some investigators apply the latter term as a general one, limiting the former to such microbes as are believed to be special disease producers. The "Germ Theory" teaches that the seeds or _spores_ of bacteria, floating in the air we breathe or in the water we drink, are taken into our bodies where, under conditions favorable to their growth, they develop, multiply, and, each after its own species, produce distinctive evil results.--Thus, according to this theory, there are special varieties of microbes that cause, respectively, diphtheria, erysipelas, scarlatina, cholera, etc.--One of the most common microbes in nature is the bacterium of putrefaction, found everywhere in decaying organic matter. [Footnote: This is the microbe found in impure water. If we take half a glass of spring or river water, and leave it uncovered for a few days, we shall observe upon it a thin coating of what appears to be a fine dust. Place, now, a drop of this dusty water under a cover glass, and examine it under a microscope with a magnifying power of about five hundred diameters. The revelation is astonishing. "The whole field of the microscope is in motion; hundreds of bacteria, resembling minute transparent worms, are swimming in every direction with an undulatory motion like that of an eel or snake. Some are detached, others united in pairs, others in chains or chaplets or cylindrical rods....All these forms represent the different transformations of _Bacterium termo_, or the microbe of putrefaction. Those which are dead appear as small, rigid, and immovable rods."--TROUESSART.]

By the species of microbes called ferments all fermented liquors are artificially produced (see p. 132); these also cause the "rising" of bread.--These wonderful little existences are thus made to perform an important part in the economy of Nature. "Nourished at the expense of putrefying organic matter, they reduce its complex constituents into soluble mineral substances, which they return to the soil to serve afresh for the nourishment of similar plants. Thus they clear the surface of the earth from dead bodies and fecal matter, and from all the useless substances which are the refuse of life; and thus they unite animals and plants in an endless chain."--TROUESSART.
