NEW BOOKS 



Animal Communities in Temperate America. By Victor E. Shelford, Instructor in Zoology in 

 the University of Chicago. 



This volume by Dr. Shelford presents the principles of field ecology, illustrated by the more 

 widely distributed animal habitats of the eastern half of temperate North America, and the aquatic 

 habitats of a much larger territory. Six chapters deal with general principles. 



In several chapters the animal communities of lakes, streams, swamps, forests, prairies, and 

 various soils and topographic situations are considered from the point of view of modem djTiamic 

 ecology. A very valuable feature of the book is the three hundred figures of widely distributed 

 animals chosen to represent the chief types of animal communities and their characteristic modes 

 of life. 380 pages, 8vo., cloth; S3.22 postpaid. 



Artificial Parthenogenesis and Fertilization. By Jacques Loeb, Member of the Rockefeller Insti- 

 tute for Medical Research. 



This new work presents the first complete treatment of the subject of artificial parthenogenesis 

 in English. Professor Loeb published four years ago a book in German under the title Die chem- 

 ische Entwicklungserregung des tierisohen Eies. Mr. W. O. R. King, of the University of Leeds, 

 England, translated the book into English, and the translation has been revised, enlarged, and 

 brought up to date by Professor Loeb. It gives, as the author says in the preface, an account of 

 the various methods by which unfertilized eggs can be caused to develop by physico-chemical means, 

 and the conclusions which can be drawn from them concerning the mechanism by which the sper- 

 matozoon induces development. Since the problem of fertilization is intimately connected with so 

 many different problems of physiology and pathology, the bearing of the facts recorded and dis- 

 cussed in the book goes beyond the special problem indicated by the title. 

 318 pages, 12mo, cloth; $2.68 postpaid.
