"NEUE BEITRAGE ZUR ENTWICKLUNGSMECHANIK 

 DER NEMATODEN" 

 1959 

 by O. zur Strassen E. Schweizerbart'sche 



(Zoologica. Band 38. Lieferung 3, Verlagsbuchhandlung 



Heft 107) Stuttgart 



142 pp.. 139 figs, 

 (paper bound) 



This monograph contains a wealth of descriptive data on the development 

 of a large number of Nematode species, based on extremely careful observa- 

 tions. The descriptive parts certainly are the most valuable aspect of the book, 

 which is richly illustrated with line drawings. 



The experimental approach is lacking entirely. Consequently most of what is presented 

 as explanation and interpretation of developmental events is of a highly speculative nature. 



"GESTATION"

This report is a sequel to the series of reports announced in the seventh full 

 issue (p. 216) and the eighth full issue (p. 246). It contains reports and 

 discussions on the (comparative) biology of the placenta, circulation in the 

 placenta, venous drainage from the uterus, and genetic factors in prolonged 

 gestation in cattle, and finally a general group discussion, touching upon a 

 variety of subjects concerning the placenta and the fetal membranes.

"ASEXUAL PROPAGATION AND REGENERATION" 



1960 

 by M. A. Vorontsova and Pergamon Press 



L. D. Liosner Oxford, London, New York. Paris 



489 pp., 210 figs. Price: 70 s 



This book is a translation from the Russian. It is based on a course of 

 lectures given at Moscow University by the first author. The book combines 

 information on regeneration and on asexual propagation (a better name for the 

 latter field would probably be "somatic embryogenesis"). These two fields are 

 closely related, their common basis being development starting from somatic 

 (non-sexual) cells.
