eluding the possible influence of domestication), and the occurrence and 

 causation of atavisms. 



The book contains a bibliography of considerable size, which has been 

 brought entirely up-to-date. The majority of the titles are by European 

 (predominantly German-speaking) authors. 



10. "LABORATORY STUDIES IN DEVELOPMENTAL ANATOMY"

 by Th. W. Torrey Burgess Publ. Cy. 



113 pp., 41 figs. Minneapolis 15, Minn. 



Price: $ 3.00 



This is a revised edition of a manual originally reviewed in the Supplement

 sections on skin and musculature, and additional material on the mammalian 

 nervous system.

 Vertebrates" which is reviewed below. 



11. "MORPHOGENESIS OF THE VERTEBRATES" 



1962 



by Th. W. Torrey John Wiley 6 Sons, Inc. 



606 pp., 325 figs. New York — London 



Price: $ 9.95 



The approach followed in this book is unique in that it integrates into a 

 single unified treatment both the comparative anatomy and the embryology 

 of the vertebrates. This is done in a way suitable for students, but the treat- 

 ment is nonetheless rigorous. Stress is placed on the origin of form, but 

 functional aspects are not ignored. 



The book is in three parts, of which the first (57 pages) starts with a 

 discussion of the relationships between phylogeny and ontogeny and of some 

 other theoretical points, then continues with a treatment of the body plan, 

 classification and evolution of vertebrates, and concludes with a brief general 

 outline of vertebrate embryogeny. 



Part two (113 pages) deals with gametes, fertihzation, cleavage, germ layer 

 formation, and early human development and placentation (including an 

 outline of reproductive physiology). 



Part three is the largest part (384 pages). It deals with the development 

 and comparative anatomy of the various organ systems. 



Throughout the text one finds "excursions" into certain special problems, 

 printed in smaller type. At the end of each chapter a list of selected references 

 are meant for students who want to penetrate more deeply into the subject. 



The illustrative material used in the book is of excellent quality. Almost all 

 line drawings are original. They are supplemented by numerous very good 

 photographical illustrations. 



The book is concluded by an extensive glossary and a detailed subject 

 index.
