First Book in Physiology and Hygiene

First Book in Physiology and Hygiene is a classic health and wellness text by J.H. Kellogg. There is no subject in the presentation of which object-teaching may be employed with greater facility and profit than in teaching Physiology, and none which may be more advantageously impressed upon the student's mind by means of simple experimentation than the subject of Hygiene. Every teacher who uses this book is urgently requested to supplement each lesson by the use of object-teaching or experiments.
