Excerpt from Hygiene for Girls Health is not a thing of chance, but is governed by certain fixed laws. These laws are but imperfectly understood, and our knowl edge of them is continually progressing. In the present state of medical science a com prehensive study of them is the labor of a life, and should therefore be undertaken only by those who are able and Willing to, devote their lives to the subject. Necessarily, such individuals constitute but a small portion of mankind. It is to them that all others must look for special instruction as to the preser vation of health, and the most probable means of regaining it when it has been lost.
