Excerpt from Introductory Physiology and Hygiene: For Use in Primary Grades As in the elementary book, the effect of alcohol and nar coties is treated in direct connection with the various organs and functions of the body concerned. The illustrations have been carefully selected with a view toward helping pupils to understand the text and toward stimulating them to healthful activity. The author is especially indebted to the Young Men's Christian Association of New York City for their courtesy in allowing the reproduction of several illustrations of their outdoor games and sports.
