Daugherty's Economic Zoology 



This work is issued, for convenience, in two parts. Part I is a Field 

 and Laboratory Guide, interleaved for notes. Part II is the textbook 

 part or the Principles. Not only does this work give the salient facta 

 of structural zoology and the development of the various branches of 

 animals, but also the natural history— the life and habits. 

 J. Remsen Bishop, Ph.D., Eastern High School, Detroit: "The 

 illustrations alone prove the book superior to any other on the sub- 

 ject. The text seems to cover the ground very thoroughly."

Drew's Invertebrate Zoology 



Professor Drew's work gives the student a working knowledge of com- 

 parative anatomy and leads him to an appreciation of the adaptation 

 of the animals to their environments. The type method is followed. 

 Prof. John H. Tyler, Amherst College : " It covers the ground well, 

 is clear and very compact. The table of definitions is excellent."

Stiles' Nutritional Physiology 



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

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

 nutrition— in the triinsformation of energy. A valuable feature is 

 Dr. Stiles' happy use of homely similes. 



Prof. Colin C. Stewart, Dartmouth College : " It is remarkable for 

 the fineness of its diction and for its clear presentation of the subject. ' '
