=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.
