Assistant Professor of Zoology in the University of Michigan 



A TEXT-BOOK INTENDED FOR THE USE OF STUDENTS 

 IN COLLEGES AND UNIVERSITIES 



Illustrated, 12mo, $1.90 



"There are some interesting distinctive features in this new introduc- 

 tion to zoology. Only a few types are studied (all of them Invertebrates) ; 

 they are discussed so as to illustrate the principles of the science; the 

 morphological aspect is not especially emphasized, but is coordinated 

 with the physiological aspect (which, of course, includes the study of 

 interrelations and behavior)." 



"The author shows a keen educative instinct ; there is a marked 

 freshness and individuality of treatment, and the assistance of a number 

 of experts, who have read particular chapters, has secured an enviable 

 freedom from mistakes. There is a very useful bibliography, and a glos- 

 sary." 



" It is a work which it has been a pleasure to read, and which de- 

 serves a career of much usefulness." Nature. 



"The book is cordially recommended as giving a thorough prepara- 

 tion for advanced courses in the subject."

"The attempt is made to present the newer zoology to the beginner. 

 Here we find the figures of Jennings, Yerkes, Morgan in fact, it may be 

 called an American product from cover to cover. Consequently, the 

 student finds himself at home at once among American forms and Ameri- 

 can names. It is not to be understood, however, that the view is circum- 

 scribed and that the data from foreign sources are eliminated." 



"It may be said that the result is excellent in the light of the labor 

 set before the author. The book-making is good, the illustrations are 

 carefully selected, and there is a unity in the volume which appeals very 

 strongly to the reviewer." Science.
