The process of administration is thus described:—
The syringe punctures the cuticle, or scarf-skin, and the cutis, or true skin, and then enters the subcutaneous or cellular tissue which covers the muscles, or flesh. Through all the tissues of the body run the lymphatics, which convey the injected matter to the lymph channels, these in turn to the veins, and thence throughout the system. A half ounce of the fluid will be distributed in from one to three hours. Sometimes the subject might feel the stimulus very quickly, and in some cases hours might elapse before any effect was felt. The human system is able to absorb almost an unlimited amount of this liquid, if administered properly and if pure.
Epidemics.—The history of severe plagues is remarkable. The first great pestilence in a comparatively civilized nation was the one at Athens about 400 B. C. On account of being shut up by the Spartans in their crowded city the Athenians had this terrible experience. It carried off thousands—nearly two-thirds of the population. In the reign of the Emperor Justinian no less than 100,000,000 inhabitants died in thirty years from a pestilence that swept from Persia to Gaul. Later, in the fourteenth century, the plague of beautiful Florence in Italy killed 80,000 people in six months. In 1665-66 London was a vast pest-house and during September of 1666 the weekly death rate reached the number of 8,000. In America the sunny South has witnessed the blasting effects of yellow fever during the last fifteen years. In 1878, Florida had 2,649 deaths, and New Orleans 3,977 from yellow fever. Fully 33% of those attacked succumbed. In the same year 4,200 people died of it at Memphis. The last important run of this epidemic was in 1888, at Jacksonville and Decatur. There the deaths averaged 10% of those attacked.
The duration of the infection stages of various diseases is thus given by Dr. T. F. Pearse, an English physician: Measles, from the 2d day of the disease for 3 weeks; small-pox, from the 1st day for 4 weeks; scarlet fever, from the 4th day for 7 weeks; mumps, from the 2d day for 3 weeks; diphtheria, from the 1st day for 3 weeks. The incubation periods, or intervals occurring between exposure to infection and the first symptoms, are as follows: Whooping-cough, 14 days; mumps, 18 days; measles, 10 days; small-pox, 12 days; scarlet fever, 3 days; diphtheria, 14 days.
Scarlet fever is at its minimum from January to May, and at its maximum in October and November. Diphtheria is more evenly distributed through the year, and is most dangerous a little later than scarlet fever. Measles and whooping-cough seem to be somewhat aggravated by cold weather, but are most fatal in May and June. Hot weather is adverse to small-pox, and favorable to disorders of the bowels, particularly in children.
THE DIFFERENCE BETWEEN MEASLES AND SMALL-POX.—At the outset of a popular eruption it is often difficult to decide whether the case is one of measles or of small-pox. M. Grisol's method of diagnosis is as follows (Medical Times): "If, upon stretching a portion of the skin, the papule becomes impalpable to the touch, the eruption is caused by measles; if, on the contrary, the papule is still felt when the skin is drawn out, the eruption is the result of small-pox."
Erysipelas.—It has long been known that an attack of erysipelas exerts a remarkable influence upon other diseases, and the attempt has been made to cure more serious maladies by deliberately inoculating the patient with the virus of erysipelas. In a recent case in Norway, the growth of a cancer was greatly retarded by this means, and life was probably prolonged a few weeks or even months, though no cure was effected.
Exercise.—Ben. Hogan, the reformed pugilist, has advanced some practical ideas:—
"In every city there are thousands of rich men and women who are ready to commit suicide because of ill-health. 'What is wealth without health?' they say. 'Nothing,' I should say; but I do say that, while every man cannot amass wealth, every man can secure good health. I know a man who owns a fine horse. He employs two men to take care of that horse and keep him in condition. He is exercised, sponged, and blanketed daily. Does the owner himself have a man to take care of him?—No. He possibly bathes once a week. He arises at 8 o'clock in the morning, throws his breakfast down without masticating it, and madly rushes off to his business. At noon he rushes into a restaurant and eats his dinner in five minutes. On he goes, hiring men to look after the health of his horse, but never stops to think of his own body and its needs.
"A man cannot digest his food unless he eats carefully. A meal should never be eaten in less than one hour. Gladstone says he bites each piece of meat he puts into his mouth twenty times before he swallows it, and that isn't too often. The men of to-day who throw their food into their stomach are physical wrecks in fifteen years. The American doctor studies medicine when he should study nature; instead of trying to prevent disease, they try to cure. There are many people who do not take a bath in two years and they prematurely die from poisoning. The poison that accumulates under the first layer of skin breeds disease and sooner or later must come death.
