Thirty-one needed glasses.

Six needed more nourishing food.

This meant that more than 52,000 of the number needed some medical care that they would not have received at home because their parents had never noticed the need of it. Every one of them could by prompt attention, a small dentist's bill, a slight operation of the throat or nose, or the use of glasses, (almost 25,000 needed glasses) be saved great suffering or inability to work in later life.

As we learn more of disease, and especially of germ diseases, we are oppressed by the feeling that we are in constant danger, but we must bear in mind that it is the weak and unfit that are attacked, and that fitness, while partly inherited, is almost altogether a matter of proper hygiene. Keeping our bodily defenses in good condition against disease is as much a matter of necessity and good policy as keeping the defenses of a city in fighting condition in time of war.

That life may be prolonged and so strengthened that the average height, weight, and endurance will be increased, admits of no doubt. The same rule of cultivation runs through all nature. The original or natural apple was a small, sour, bitter crab. The difference between that and the finest products of western orchards, is altogether a matter of cultivation, selection, and proper treatment. In 1710 the average weight of dressed cattle did not exceed three hundred and seventy pounds. Now it is not far from one thousand pounds. An equal change could be made in the human race, but because we believe so fully in personal liberty to live our lives as we choose, little has actually been done to raise the human standard.

The care and hygiene of children is receiving universal attention, with the result of a wonderful reduction in the sickness and death of children, but as yet comparatively few grown persons apply these lessons to their own lives, and the rates for older persons remain almost unchanged.

When individuals have done all that they can, there still remains much that must be done by the city, the state, and the nation. Boards of health can do much toward controlling epidemics by placing infected households under quarantine, by compelling householders who are ignorant or careless to clean their premises and to take other precautions for the public health.

Hospitals, both public and private, have done excellent work, not only in curing disease but in gaining more definite knowledge of the nature of diseases through the study of large numbers of cases.

The cleaning of streets and the removal of garbage regularly are among the great factors in keeping a city in a sanitary condition. New Orleans and some of the cities of Cuba and Porto Rico show strikingly what may be done in that direction.

Medical inspection of schools is a new and valuable aid to health. Epidemics of childish diseases which sweep through the schools with a fearful record of illness and a lesser one of death, may often be checked entirely by the close watch of the medical inspector, who removes the first patients from the schools when the disease is in its beginning.
