ZOOLOGY. 



Kellogg's American Insects.^— It is gratifying to observe the great 

 progress that is being made in the science of entomology, and to 

 welcome a book such as the author now brings before the public. 

 While the biological side is strongly emphasized it is not overdone 

 and we have the subject presented in a much broader sense than 

 has perhaps ever been done in a single volume. It is written in a 

 clear and popular style, and the fact that the species of economic 

 importance are more fully treated adds much towards making the 

 work of general interest. The 674 pages are illustrated by over 

 800 figures in the text and 18 colored plates, well selected to show 

 the biologic, systematic, and economic features in the study of insect 

 life. 



The first chapter treats of the structure and special physiology of 

 insects, and the second of the development and metamorjjhosis, 

 followed by the classification and description of tlic various groups
