5. _The Cellar_.--_A Typical Bad Cellar_.--Did the reader ever, when a child, see the cellar afloat at some old home in the country? You creep part way down the cellar stairs with only the light of a single tallow candle, and behold by its dim glimmer an expanse of dark water, boundless as the sea. On its surface, in dire confusion, float barrels and boxes, butter firkins and washtubs, boards, planks, hoops, and staves without number, interspersed with apples, turnips, and cabbages, while half-drowned rats and mice, scrambling up the stairway for dear life, drive you affrighted back to the kitchen....Now consider the case of one of these old farmhouse cellars that has been in use fifty years or more. In it have been stored all the potatoes, turnips, cabbages, onions, and other vegetables for family food. The milk and cream, the pork and beef, and cider and vinegar, have all met with various accidents, and from time to time have had their juices, in various stages of decay, absorbed by the soil of the cellar bottom. The cats have slept there to fight the rats and the mice, who have had their little homes behind the walls for half a century; and the sink spouts have for the same term poured into the soil close by, their fragrant fluids. The water rushes upward and sideways into the cellar, forming, with the savory ingredients at which we have delicately hinted, a sort of broth, quite thin and watery at first, but growing thicker as the water slowly subsides and leaves its grosser parts pervading the surface of the earth, walls, and partitions. All this time the air rushes in at the openings of the cellar, and presses constantly upward, often lifting the carpets from the floors, and is breathed day and night by all who dwell in the house. Does it require learned doctors or boards of health to inform any rational person that these conditions are unfavorable to health?--MRS. PLUNKETT, _Women, Plumbers, and Doctors_.

_What Came from a Crack in a Cellar Wall_.--A few years ago a Boston gentleman inherited a house, situated on one of the most desirable streets of the city. Resolving to make a healthy as well as a beautiful home, he. spent a large sum, and gave personal supervision to all the details of an elaborate system of plumbing. He moved in. Imagine his grief and disappointment when member after member of his family succumbed to diphtheria, and an infant and a grown daughter died. Though so deeply smitten, he did not lose his belief in the connection between cause and effect. He ordered a minute investigation of the premises by experts. A slight crack, so small as to have escaped ordinary observation, was found in the cellar wall. Investigation of the premises next door--the inmates of which were also suffering from diphtheria--showed a choked-up drain, which ought to have connected with the sewer, but did not. The filthy ooze from this was pouring out, just where its effluvium and its disease germs could pass without any hindrance through the crack.

Now that it is shown that gases pass through bricks and many kinds of stone, it is easy to see that the sanitary welfare of one is the sanitary welfare of all.--MRS. PLUNKETT.

6. _The Bedroom_.--_The Bed a Night Garment_.--There is still one of our garments to be considered, which generally is not regarded as such. I mean the bed--that piece of clothing in which we spend such a great part of our time.

The bed is not only a place of rest; it is especially our sleeping garment, and has often to make up for privations endured during the day and the day's work, and to give us strength for to-morrow. Like our day garments, the bed covering must be airy and warm at the same time. We warm the bed by our body, just as we warm our clothes, and the bed warms the air which is continually flowing through it from below, upward. The regulating strata must be more powerful in their action than in our day clothes, because during rest and sleep the metamorphosis of our tissues and the resulting heat become less; and because in a horizontal position we lose more heat by an ascending current of air than in a vertical position, where the warm ascending current is in more complete and longer contact with our upright body.

The warmth of the bed sustains the circulation in our surface to a certain degree for the benefit of our internal organs at a time when our production of heat is at its lowest ebb. Hence the importance of the bed for our heat and blood economy. Several days without rest in a bed not only make us sensible of a deficiency in the recruiting of our strength, but very often produce quite noticeable perturbations in our bodily economy, from which the bed would have protected us.--DR. MAX VON PETTENKOFFER.

_Bed Ventilation_.--It often happens that the desire of the energetic housekeeper to have her work done at an early hour in the morning, causes her to leave one of the most important items of neatness undone. The most effectual purifying of bed and bedclothes can not take place, if the proper time is not allowed, for the free circulation of pure air, to remove all human impurities which have collected during the hours of slumber. At least two or three hours should be allowed for the complete removal of atoms of insensible perspiration which are absorbed by the bed. Every day the airing should be done; and, occasionally, bedding constantly used should be carried into the open air, and left exposed to the sun and wind for half a day.--_Home and Health_.

CIRCULATION.

THE PULSE (p. 116).--The pulse which is felt by the finger does not correspond precisely with the beat of the heart, but takes place a little after it, and the interval is longer, the greater the distance of the artery from the heart. The beat of the artery on the inner side of the ankle, for example, is a little later than the beat of the artery in the temple.--HUXLEY.

The pulse is increased by exertion, and thus is more rapid in a standing than in a sitting, and in a sitting than in a lying posture. It is quickened by meals, and while varying thus from time to time during the day, is on the whole quicker in the evening than in early morning. It is said to be quicker in summer than in winter. Even independently of muscular exertion, it seems to be quickened by great altitude. Its rate is also profoundly influenced by mental conditions.--FOSTER.

CIRCULATION OF THE BLOOD IN THE BRAIN (p. l20).--Signer Mosso, who has been engaged on the subject for six years, has published some new observations on the different conditions of the circulation of the blood in the brain. He has had the privilege of observing three patients who had holes in their skulls, permitting the examination of the encephalic movements and circulation. No part of the body exhibits a pulsation so varied in its form as the brain. The pulsation may be described as tricuspid; that is, it consists of a strong beat, preceded and followed by lesser beats. It gathers strength when the brain is at work, corresponding with the more rapid flow of blood to the organ. The increase in the volume of the brain does not depend upon any change in the respiratory rhythm; for, if we take the pulse of the forearm simultaneously with that of the brain, we can not perceive that the cerebral labor exercises any influence upon the forearm, although the pulsation in the brain may be considerably modified. The emotions have a similar effect upon the circulation of the brain to that of cerebral labor. Signor Mosso has also observed and registered graphically the variations of the cerebral pulse during sleep. Generally the pulses of the wrist and the brain vary oppositely. At the moment of waking, the pulse of the wrist diminishes, while that of the brain increases. The cerebral pulsations diminish as sleep grows deeper, and at last become very weak. Outward excitations determine the same modifications during sleep as in the waking state, without waking the sleeper. A deep inspiration always produces a diminution in the volume of the brain, in consequence, probably, of the increased flow of blood into the veins of the thoracic cavity; the increase of volume in the brain, when it takes place, is, on the contrary, due to a more abundant flow of arterial blood to the encephalus.--_Popular Science Monthly, March, 1882_.

CATARRHAL COLDS (p. l30).--I maintain that it can be proved, with as absolute certainty as any physiological fact admits of being proved, that warm, vitiated indoor air is the cause, and cold outdoor air the best cure, of catarrh....Fresh cold air is a tonic that invigorates the respiratory organs when all other stimulants fail, and, combined with arm exercise and certain dietetic alternatives, it is the best remedy for all disorders of the lungs and upper air passages....A combination of the three specifics,--exercise, abstinence, and fresh air,--will cure the most obstinate cold....Frost is such a powerful disinfectant, that in very cold nights the lung-poisoning atmosphere of few houses can resist its purifying influence; in spite of padded doors, in spite of "weatherstrips" and double windows, it reduces the indoor temperature enough to paralyze the floating disease germs. The penetrative force of a polar night frost exercises that function with such resistless vigor that it defies the preventive measures of human skill; and all Arctic travelers agree that among the natives of Iceland, Greenland, and Labrador pulmonary diseases are actually unknown. Protracted cold weather thus prevents epidemic catarrhs, but during the first thaw Nature succumbs to art: smoldering stove fires add their fumes to the effluvia of the dormitory, tight- fitting doors and windows exclude the means of salvation; superstition triumphs; the lung poison operates, and the next morning a snuffling, coughing, and red-nosed family discuss the cause of their affliction....It is a mistake to suppose that "colds" can be propagated only by direct transmission or the breathing of recently Vitiated air. Catarrh germs, floating in the atmosphere of an ill-ventilated bedroom, may preserve their vitality for weeks after the house has been abandoned; and the next renter of such a place should not move in till wide-open windows and doors and a thorough draught of several days have removed every trace of a "musty" smell.--DR. FELIX L. OSWALD, _Remedies of Nature, Popular Science Monthly, March, 1884_.

CATCHING COLD.--The phrase "to catch cold," so often in the mouths of physicians and patients, is a curious solecism. It implies that the term "cold" denotes something positive--a sort of demon which does not catch, but is caught by the unfortunate victims....If most persons outside of the medical profession were to be asked what they consider as chiefly to be avoided in the management of sick people, the answer would probably be "catching cold." I suspect that this question would be answered in the same way by not a few physicians. Hence it is that sick rooms are poorly ventilated, and patients are oppressed by a superabundance of garments and bedclothes. The air which patients are made to breathe, having been already breathed and rebreathed, is loaded with pulmonary exhalations. Cutaneous emanations are allowed to remain in contact with the body, as well as to pervade the atmosphere. Patients not confined to the bed, especially those affected with pulmonary disease, are overloaded with clothing, which becomes saturated with perspiration, and is seldom changed, for fear of the dreaded "cold."...

A reform is greatly needed in respect to "catching cold." Few diseases are referable to the agency of cold, and even the affection commonly called a cold is generally caused by other agencies, or, perhaps, by a special agent, which may prove to be a microbe. Let the axiom, _A fever patient never catches cold_, be reiterated until it becomes a household phrase. Let the restorative influence of cool, fresh, pure atmosphere be inculcated. Let it be understood that in therapeutics, as in hygiene, the single word _comfort_ embodies the principles which should regulate coverings and clothing.--AUSTIN FLINT, M.D., _in a Lecture printed in The New York Medical Journal_.

DIGESTION AND FOOD.

THE WATER WE DRINK (p. l55).--_Qualities of Pure Water_.--"A good drinking water," says Dr. Simpson (in _The Water We Drink_), "should possess the following physical characters: it should be entirely free from color, taste, or odor; it should, moreover, be cool, well aerated, soft, bright, and entirely free from all deposit. But it should be remembered that a water having all these characteristics may yet be more or less polluted by organic matter, owing to the proximity of drains and sewers....Disease has frequently been traced to the use of perfectly bright and clear water, where there was no sediment, and where the animal organic matter was held in a state of solution."

In the case of diseases, such as typhoid, which attack the stomach, disease germs are removed along with the excreta; and if, as is often the case, the drainage of an infected town flows into a river, and that river is used in some after portion of its course as a water supply, there is great danger of such diseases being communicated. For, however well the water may be purified and filtered, we have no guarantee that it will not contain some of these disease germs, which are so small that they pass through the finest filters. It is in this way that almost all the great cholera and typhoid epidemics have spread.--_Chambers's Journal_.

_Well Water Often Dangerous_.--A densely crowded population soon impregnates the soil to some depth with filth, which drains into the water course below, especially if such water is near the surface. This surface water easily penetrates a loosely walled well. Every well, therefore, should not only be widely separated from barnyards, cesspools, pens, sinks, and similar places, but should be made water-tight with cement, so that nothing can reach its interior except water that has been filtered through dense beds of unpolluted ground below. If these precautions are neglected, the best and deepest well may become continually contaminated by infiltration from the surrounding surface. This impure water, even when not used for family drinking, is sometimes supplied to cows, or used for washing dairy pans, or employed in diluting milk for the market, and there are many known cases in which disease has thus been disseminated. Thus, an epidemic of typhoid fever in Cambridge, Mass., was definitely traced to a dairy which supplied the victims with milk. Upon investigation it was found that a short time before there had been a typhoid patient in the farmhouse, and that the well from which water was taken to wash the milk pans had become contaminated with the specific poison brought into it from the surrounding drainage.

All suspected water should be thoroughly boiled before using it to drink. Some physicians insist that the boiling should continue for one or two hours in order entirely to destroy the bacterial germs. The heaviness and insipidity incident to boiled water may be somewhat relieved by afterward filtering it. Filtering, of itself, however, will do little toward ridding the water of microbes, which are much too minute to be arrested by the ordinary apparatus.--When journeying, where one must often take a hasty meal at a railway station, drink hot water in preference to cold. A convenient portable filter may be arranged with a bottle of powdered charcoal, and a piece of filtering paper. A traveler by briskly stirring a tablespoonful of the charcoal into a pint of water, allowing it to stand five or ten minutes, and then filtering it through the paper, may venture to relieve his thirst in almost any part of the country.

_Water an Absorbent of Foul Gases_.--If a pitcher of water be left uncovered in an occupied apartment for only a few hours, it will become foul from the absorption of the respired and perspired gases in the room. The colder the water, the greater the capacity to contain these gases. Water kept in a room over night is therefore unfit for drinking, and should not be used even to brush the teeth or to gargle in the throat.

_Impure Ice, a Breeder of Disease_.--We generally take the purity of our ice for granted, and, like the alligator in the bayou, close our mouths and swallow it. In the country, I have seen during the ice- harvesting season, wagon after wagon passing me on the road, laden with ice that had been collected from canals, rivers, and streams receiving sewerage, and from ponds that are in the summer time reeking with slime, and often offensive from the quantity of decomposed vegetable and animal matter brought in by the washing from the meadow. These streams would be shunned as a source of water supply.

Should you interview a native regarding the slimy mud puddle before you, called Mr. So-and-so's private "ice pond," he would say that "in winter it is much better, and when frozen, you know, it makes fine ice," presenting that popular though ignorant belief that while in the act of crystallizing, water rids itself of all its injurious qualities, however offensive it may be in its liquid state. Unfortunately, there is enough truth in the current idea of the elimination of noxious and foreign matter during the process of freezing to give color to the popular belief, but not enough to make it a safe reliance; therefore all means should be used to enlighten the public regarding this subject. Experiment has shown that freezing produces little change or effect in overcoming the poisonous influences, and ice has often served as a vehicle to convey the germs of typhoid and other low forms of fever. Pure ice can be procured only from water free from impurities, and ice for domestic or surgical purposes should never be collected from ponds or streams which contain animal or vegetable refuse, or stagnant and muddy material.--_Journal of Reconstructives, Oct., 1887_.

THE GLANDULAR COAT OF THE STOMACH, AND HOW IT WEEPS (p. l62).--While the food is thus being continually moved about, it is at the same time subjected to the action of the chemical sac. This is, as we have said, a glandular sac. It is of some thickness, and is made of little glands bound up together with that stringy fibrous packing material which anatomists call _connective tissue_.

If we were to imagine many gross of small India-rubber vials all placed side by side, and bound together with hay or straw into a great mat, and the mat rolled up into a sac, with all the mouths of the vials turned inward, we should have a large and coarse, but tolerably fair image of the glandular coat of the stomach. Each vial would then represent one of the glands of this coat, one of the gastric or peptic glands, as they are called. Each gland, however, is not always a simple tube, but is often branched at the bottom end, and all of them are lined, except just at their mouths, with large rounded bodies, which not unfrequently almost choke up their cavity.

FIG. 72.

The rounded masses, or cells, as they are called, in the interior of each gland, form the really active part of the apparatus. Each cell is a little laboratory, which concocts out of the material brought to it or near it by the blood a certain potent, biting fluid, and is hence called a peptic or digestive cell. Each cell is born at the bottom of the tube, and in process of time travels upward toward the mouth. When it reaches the mouth, it bursts, and pours into the stomach the fluid it has elaborated, or perhaps may give it out without bursting, while it is still within its tube.

In those cases in which it has been possible to look in upon the stomach while at work (as in the famous case of Alexis St. Martin), and where the orifices of the tiny glands (for though we have compared them to bottles, they are exceedingly small) appear like little dots, tears were seen to start at the mouths of the glands, gather into drops, and finally trickle down into the lowest part of the stomach. The stomach, as it were, weeps, and indeed the weeping of tears is just such another effect of glandular activity--only ordinary tears form a mild and, chemically speaking, impotent fluid; while the fluid which the tears of the stomach weep--the _gastric juice_--is a sharp, piercing water of excessive chemical power.--Hinton.

POISONOUS MILK, CHEESE, AND ICE CREAM (p. l69).--In late years there have been many cases of poisoning by ice cream, cheese, and milk. The poisonous principle sometimes developed in these articles of food has been made a subject of special investigation, and it has been found to be due to natural causes. Dr. Vaughan, of Michigan, after spending several months in experimenting upon samples of twelve different cheeses, which had caused three hundred cases of poisoning, finally succeeded in isolating certain poison crystals, which he calls _Tyrotoxicon_. He says: "A few drops of an aqueous solution of these crystals placed upon the tongue produces all the symptoms observed in those who had been made sick by eating of the cheese. This was tried repeatedly upon myself, and upon some of my students who kindly offered themselves for experimentation." Dr. Vaughan afterward procured the poison crystals from milk which had stood some months in a closed bottle, and also from a sample of ice cream by which eighteen persons had been made ill. It was learned in the latter case that the custard, of which the ice cream was made, had been allowed to stand in a foul atmosphere for two hours before it was frozen. By placing small bits of this poisonous cream in good milk, and allowing it to stand twenty-four hours, the whole became vitiated. This proved that the poison is due to the growth of some ferment. In the autumn of 1886, many persons in different hotels at Long Branch were poisoned by milk obtained from a certain milkman. In this case it was found that the cows were milked at noon, the warm milk being immediately placed in cans and carted eight miles during the warmest part of the day, in a very hot month. In June, 1887, nineteen persons in New York city were similarly poisoned by milk which also came from one dairy. Many of these persons had narrow escapes from death. These, and many other like instances, teach us the importance of the greatest care in every detail of milk handling. A little dried milk formed along the seam of a tin pail, or any similar lodging place, may be the starting point of poison generation. A month after his first experiments with the ice cream mentioned above, Dr. Vaughan put small pieces of the dried custard in pans of milk, and afterward made custard from this milk. This yielded tyrotoxicon as before, showing the tenacious vitality of the poison, and also explaining the fact that the precise cause of poisoning is in many cases so difficult to trace.

FISH AS FOOD (p. 169).--It is not desirable that fish should be the sole kind of nitrogenous food eaten by any nation; and even if milk and eggs be added thereto, the vigor of such a people will not be equal to that of flesh-eating nations. At the same time, the value of fish as a part of a dietary is indicated by the larger proportion of phosphorus which it contains, and which renders it especially fitted for the use of those who perform much brain work, or who are the victims of much anxiety and distress.--EDWARD SMITH, _in "Foods_."
