¶ The effects of alcohol and other stimulants and narcotics are treated in each book sensibly, and with sufficient fullness. But while this important form of intemperance is singled out, it is borne in mind that the breaking of any of nature’s laws is also a form of intemperance, and that the whole study of applied physiology is to encourage a more healthful and a more self-denying mode of life.

¶ In the preparation of this series the needs of the various school grades have been fully considered. Each book is well suited to the pupils for whom it is designed.
