or cream necessarily kill germs that may be contained in it.
Raw milk plays so important a part in the spread of disease that its fitness for human consumption is open to serious question. Certified milk, where obtainable, is safe but expensive. Boiled milk is safe, but changed in taste and to some extent in quality. If milk is heated to 142°-145° F. and kept at that temperature for 30 minutes all disease germs in it are killed. This process, called pasteurization, renders milk safe. The objection is sometimes made that continued use of pasteurized milk for infants causes scurvy, but in New York City where over 90 per cent. of the milk is pasteurized no increase in scurvy has been noticed, while a large diminution in deaths of infants from diarrhœal diseases has resulted, as in all cities where pasteurization is required.
The following is a simple method for pasteurizing a quart bottle of milk. If the directions are exactly followed the milk will be pasteurized at the end of the process; no thermometer need be used. To prevent the bottle from breaking, it is first warmed by placing it for a few minutes in a pail of warm water.
"From the results of the experiments it was concluded that any housewife can pasteurize a one quart bottle of milk by:
1. Boiling 2½ quarts of water in a large agate saucepan; or better
2. Boiling 2 quarts of water in a 10 pound tin lard pail, placing the slightly warmed bottle from the ice chest in it, covering with a cloth and setting in a warm place. At the end of one hour the bottle of milk should be removed and chilled promptly. The water must be boiled in the container in which the pasteurization is to be done."—(Ruth Vories, in "Health News," Sept., 1916.)
Elimination.
—Careful attention should be paid to elimination through the bowels and kidneys. Constipation is responsible for many common ailments; among them are headache, disinclination to work, irritable temper, and lowered resistance. If long continued, constipation becomes serious both from congestion and displacement of pelvic organs, and from absorption over a considerable time of even small amounts of the poisonous substances resulting from decomposition of food in the large intestine. The bowels can best be regulated by diet, water, exercise, and habit. The habitual use of cathartic and laxative drugs is most unwise, because they tend to aggravate the trouble. Moreover the habitual and continued use of injections and "internal baths" is harmful, and would not be considered necessary if bran and coarse flour and vegetables were substituted for concentrated foods. Greed, laziness, and lack of
intelligence lead most persons suffering with constipation to prefer pills to the restraints demanded by hygienic living. The habit of evacuating the bowels at a regular time, if established in early childhood and rigidly adhered to, will prevent constipation among most healthy people. Any person who thinks drugs necessary should consult a physician, and be prepared to follow the régime he advises over a considerable period of time and at the cost of some self-denial.
For healthy people, voiding urine presents no difficulty if a sufficient amount of water is taken; but some persons reduce the amount of liquid taken in order to escape the inconvenience of urination. This practice is harmful, and may involve insufficient cleansing of the entire system. If frequent urination disturbs sleep, liquids may be withheld during the evening; but the total amount of water taken in 24 hours should not be diminished.
Rest and Fatigue.
—A fatigued person is a poisoned person. Muscular exertion burns the fuel constituents of the body, as we recognize by the greater heat generated within us during muscular exertion. Waste products, resulting from this burning process, accumulate if not removed, and clog the body in somewhat the same way that ashes and cinders clog a furnace. The fatigued
