BOSTON, _June_ 20, 1889. 

The Pathfinder Series of Text-books on Anatomy, Physiology, and Hygiene
consists of the following volumes: 

I.  Child's Health Primer (for Primary Grades). 

II.  Hygiene for Young People or, Young People's Physiology.  (for
Intermediate Classes) 

III.  Hygienic Physiology (for Advanced Pupils). 

The above are the series originally prepared (as their general title
indicates) to supply the demand created by the laws for temperance
instruction in public schools in the United States.  They were written by
experts under the supervision of the Scientific Department of the National
Woman's Christian Temperance Union, published by the instigation of the
same, and have been carefully revised from time to time, under the same
supervision, to keep them abreast with the latest teachings of science.
