Dr. Stiles' new work takes up each organ, each secretion concerned in 

 the process of digestion, discussing the part each plays in the physiol- 

 ogy of nutrition in the transformation of energy. In fact, the key- 

 note of the book throughout is " energy" its source and its conserva- 

 tion. The illustrations and homely similes are noteworthy. 



Prof. M. E. Jaffa, University of California: " The presentation of the

Prof. Stiles' wonderful faculty of putting scientific things in language 

 within the grasp of the non-medical reader is nowhere better illustrated 

 than in this, his newest book. He has a way of conveying facts accu- 

 rately with rifle-ball precision. This new book is really a physiology 

 and anatomy of the nervous system, emphasizing the means of con- 

 serving nervous energy.

This work will help the student to organize his knowledge and to 

 appreciate the significance of the nervous system as a working mechan- 

 ism. It presents the actual inner workings of the nervous mechanisms 

 in terms that he can understand at the very beginning of his course in 

 psychology, general zoology, comparative anatomy, and general medi- 

 cine. Prof. Herrick's many years of teaching experience has impressed 

 upon him the difficulties the student finds in grasping this subject at 

 the beginning of his course. He has aimed to remove these difficulties. 

 The text is well illustrated.
