 ology, reflexes, anatomy of the nervous system, afferent nervous system,

Nutritional Physiology. By Percy G. Stiles, Instructor in Physi- 

 ology at Harvard University, Boston. i2mo of 271 pages, illus- 

 trated. Cloth, $1.25 net. 



Dr. Stiles takes up each organ, each secretion concerned with the process 

 of digestion, discussing the part each plays in the physiology of nutrition 

 — in the transformation of energy. In fact, the keynote of the book 

 throughout is " energy " — its source and its conservation. The illustra- 

 tions 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."

Economic Zoology. By L. S. Daugherty, M. S., Ph. D., Professor 

 of Zoology, State Normal School, Kirksville, Mo.; and M. C.

 pages, interleaved. Cloth, $1.25 net. Part II — Principles: i2mo

There is no other book just like this. Not only does it give the salient 

 facts of structural zoology, but also the natural history — the life and 

 habits. It emphasizes the economic phase. 



Prof. V. E. Shelf ord. University of Chicago: " It has many merits and 

 is the best book of the kind on the market.".'
