To Ease Swollen Feet. Policemen, mail carriers, and others whose occupation keeps them on their feet a great deal, often are troubled with chafed, sore and blistered feet, especially in extreme hot weather, no matter how comfortably their shoes may fit. A powder is used in the German army for sifting into the shoes and stockings of the foot soldiers, called "Fusstreupulver," and consists of three parts salicylic acid, ten parts starch and eighty-seven parts pulverized soapstone.

To increase the weight: Eat to the extent of satisfying a natural appetite, of fat meats, butter, cream, milk, cocoa, chocolate, bread, potatoes, peas, parsnips, carrots, beets, farinaceous foods, as Indian corn, rice, tapioca, sago, corn starch, pastry, custards, oatmeal, sugar, sweet wines, and ale.

When quinine will, break up a cold. It is surprising, says a family physician, how certainly a cold may be broken up by a timely dose of quinine. When first symptons make their appearance, when a little languor, slight hoarseness and ominous tightening of the nasal membranes follow exposure to draughts or sudden chill by wet, five grains of this useful alkaloid are sufficient in many cases to end the trouble. But t it must be done promptly. If the golden moment passes, nothing suffices to stop the weary sneezing, handkerchief using, red nose and woe-begone looking periods that certainly follow.
A mistaken idea. The old adage, "Feed a cold and starve a fever," is characterized by the Journal of Health as very silly advice. If anything, the reverse would be nearer right. When a person has a severe cold it is best for him to eat very lightly, especially during the first few days of the attack.
Bathing. There has been a great deal written about bathing. The surface of the skin is punctured with millions of little holes called pores. The duty of these pores is to carry the waste matter off. For instance, perspiration. Now, if these pores are stopped up they are of no use, and the body has to find some other way to get rid of its impurities. Then the liver has more than it can do. Then we take a liver pill when we ought to clean out the pores instead. The housewife is very particular to keep her sieve in good order; after she has strained a substance through it she washes it out carefully with water, because water is the best thing known. That is the reason water is used to bathe in. But the skin is a little different from a sieve, because it is willing to help along the process itself. All it needs is a little encouragement and it will accomplish wonders. What the skin wants is rubbing. If you should quietly sit down in a tub of water and as quietly get up and dry off without rubbing, your skin wouldn't be much benefited.
The water would make it a little soft, especially if it was warm. But rubbing is the great thing. Stand where the sunlight strikes a part of your body, then take a dry brush and rub it, and you will notice that countless little flakes of cuticle fly off. Every time one of these flakes is removed from the skin your body breathes a sigh of relief. An eminent German authority contends that too much bathing is a bad thing. There is much truth in this. Soap and water are good things to soften up the skin, but rubbing is what the skin wants. Every morning or every evening, or when it is most convenient, wash the body all over with water and a little ammonia, or anything which tends to make the water soft; then rub dry with a towel, and after that go over the body from top to toe with a dry brush. Try this for two or three weeks, and your skin will be like velvet.
Tea and Coffee. Tea is a nerve stimulant, pure and simple, acting like alcohol in this respect, without any value that the latter may possess as a retarder of waste. It has a special influence upon those nerve centers that supply will power, exalting their sensibility beyond normal activity, and may even produce hysterical symptoms, if carried far enough. Its active principle, theine, is an exceedingly powerful drug, chiefly employed by nerve specialists as a pain destroyer, possessing the singular quality of working toward the surface. That is to say, when a dose is administered hypodermically for sciatica, for example, the narcotic influence proceeds outward from the point of injection, instead of inward toward the centers, as does that of morphia, atropia, etc. Tea is totally devoid of nutritive value, and the habit of drinking it to excess, which so many American women indulge in, particularly in the country, is to be deplored as a cause of our American nervousness.
Coffee, on the contrary, is a nerve food. Like other concentrated foods of its class, it operates as a stimulant also, but upon a different set of nerves from tea. Taken strong in the morning, it often produces dizziness and that peculiar visual symptom of overstimulus which is called muscae volitantes - dancing flies. But this is an improper way to take it, and rightly used it is perhaps the most valuable liquid addition to the morning meal. Its active principle, caffeine, differs in all physiological respects from theine, while it is chemically very closely allied, and its limited consumption makes it impotent for harm.
To Straighten Round Shoulders. A stooping figure and a halting gait, accompanied by the unavoidable weakness of lungs incidental to a narrow chest, may be entirely cured by a very simple and easily-performed exercise of raising one's self upon the toes leisurely in a perpendicular position several times daily. To take this exercise properly one must take a perfectly upright position, with the heels together and the toes at an angle of forty-five degrees. Then drop the arms lifelessly by the sides, animating and raising the chest to its full capacity muscu-larly, the chin well drawn in, and the crown of the head feeling as if attached to a string suspended from the ceiling above. Slowly rise upon the balls of both feet to the greatest possible height, thereby exercising all the muscles of the legs and body; come again into standing position without swaying the body backward out of the perfect line. Repeat this same exercise, first on one foot, then on the other. It is wonderful what a straightening-out power this exercise has upon round shoulders and crooked backs, and one will be surprised to note how soon the lungs begin to show the effect of such expansive development.
Care of the Eyes. In consequence of the increase of affections of the eye, a specialist has recently formulated the following rules to be observed in the care of the eyes for school work: A comfortable temperature, dry and warm feet, good ventilation; clothing at the neck and other parts of the body loose; posture erect, and never read lying down -or stooping. Little study before breakfast or directly after a heavy meal; none at all at twilight or late at night; use great caution about studying after recovery from fevers; have light abundant, but not dazzling, not allowing the sun to shine on desks or on objects in front of the scholars, and letting the light come from the left hand or left and rear; hold book at right angles to the line of sight or nearly so; give eyes frequent rest by looking up. The distance of the book from the eye should be about fifteen inches. The usual indication of strain is redness of the rim of the eyelid, betokening a congested state of the inner surface, which may be accompanied with some pain.
When the eye tires easily rest is not the proper remedy, but the use of glasses of sufficient power to aid in accommodating the eye to vision.
How and When to Drink Water. According to Doctor Leuf, when water is taken into the full or partly full stomach, it does not mingle with the food, as we are taught, but passes along quickly between the food and lesser curvative toward the pylorus, through which it passes into the intestines. The secretion of mucus by the lining membrane is constant, and during the night a considerable amount accumulates in the stomach; some of its liquid portion is absorbed, and that which remains is thick and tenacious. If food is taken into the stomach when in this condition, it becomes coated with this mucus, and the secretion of the gastric juice and its action are delayed. These facts show the value of a goblet of water before breakfast. This washes out the tenacious mucus, and stimulates the gastric glands to secretion. In old and feeble persons water should not be taken cold, but it may be with great advantage taken warm or hot.
