Excerpt from Practical Health Lessons, Vol. 1
In no field of human activity has greater progress been made during recent years than in hygiene and sanitation. While the advance must always be led by a small but zealous group of workers, an accurate and up-to-date knowledge of the elementary facts of these two subjects should be the common property of all the people. It is the purpose of "Practical Health Lessons" to present to pupils in the grammar grades of the elementary schools, in clear and simple language, all the essential facts of personal hygiene and as much of public hygiene as every citizen ought to know.
Health instruction is effective only as it leads the pupil to live in accordance with the laws of health. The average grammar grade pupil will pay little heed to laws for which he sees no reason. The reasons for these laws are found partly in the structure of the body, but chiefly in the way the body works and in the nature of the external dangers to which it is exposed. To care for one's health intelligently, some knowledge of anatomy and physiology is absolutely necessary. So much - and no more - these books aim to give.
