Excerpt from The Human Body Its Health a Text-Book for Schools, Having Special Reference to the Effects of Stimulants and Narcotics, on the Human System IN making this little book, I have tried to give to the student a definite impression, in outline, of the structure and functions of the human body. To this end I have tried to omit all statements that would confuse the picture by overloading it, and all statements that could not be understood by those who will be its most numerous read ers. I have not told them, for example, that the re-action of the saliva is alkaline, and that of the gastric juice acid, because for many of them that statement would have no meaning. I have not mentioned the names of many of the muscles, because it is difficult and unnecessary to remember them. The laws of hygiene are given in connection with the facts of anatomy and physiology from which they are derived. Learned in this way, they will remain in the mind as guiding principles, and not simply as the dicta of authority. In treating of the effects of stimulants and narcotics, I have endeavored to set forth facts which are susceptible of abundant proof, and which are of the most importance, practically, to those for whom this work is designed.
