"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." 



— American Journal of Science. 



" 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.
