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 

 matter is excellent and can be understood by all."

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 book. He has a way of conveying facts accurately with 

 rifle-ball precision. This new book is really a physiology and anatomy 

 of the nervous system, emphasizing the means of conserving nervous 

 energy.

 pages, illustrated. Cloth, $1.50 net. Published July, igi6. 



This new physiology is particularly adapted for high and normal 

 schools and general colleges. It presents the accepted facts concisely 

 with only a limited description of the experiments by which these facts 

 have been established. It is written by a teacher who has not lost the 

 poiiit of view of elementary students. Professor Stiles has a unique 

 and forceful way of writing. He has the faculty of making clear, even 

 to the unscientific reader, physiologic processes more or less difficult 

 of comprehension. This he does by the use of happy teaching devices. 

 The illustrations are as simple as the tex^.
