REVIEWS. 
Outlines of Economic Zoology, by Professor Albert M. Reese, of West Virginia 
University, pp. 13 + 318, with 284 illustrations. P. Blakiston’s Son and Co., 
Philadelphia. This book should have a wide range of readers, for although 
written primarily for students undergoing a regular elementary course in general 
zoology, it should prove of deep interest to all lovers of natural history. The 
author has successfully kept the economic aspect in mind in the groups he has 
discussed without subordinating the scientific value of his work. The fourteen 
.chapters deal with fourteen separate orders, any one of which, because of its 
direct relationship with human life, constitutes a fascinating story. In the 
chapter on protozoa, for instance, there are short but highly interesting state- 
ments on several genera which are parasitic in all classes of vertebrates up to 
man. The porifera, or sponges, constitute another story of endless variety. 
Arthropoda, pisces, reptilia, and mammalia are economically, perhaps, of most 
direct interest, and the pages on these orders abound with stories of human 
interest and descriptions of scientific value. The perusal of Professor Reese’s 
little volume will certainly stimulate an appetite for further study of the subject.
