R. RUGH. 1977. A GUIDE TO VERTEBRATE DEVELOPMENT, 7th edit. 



Burgess, Minneapolis, XVIII, 390 pp., numerous figs. $ 9.95 (spiral bound) 



This new edition of a well-known students' guide has been somewhat extended. A 

 brief chapter on human development has been added, as well as a 17-page chapter entitled 

 Experimental embryology. This is entirely methodological in character; it suggests no 

 specific experiments and does not discuss the results of such experiments.

Collection of 7 published papers and preprints (1974-'77) preceded by a 17-page

This new serial publication will certainly be of great value to mammalian embryologists. 

 If the promise of the first two volumes is fulfilled it will develop into a real forum for the 

 exchange of facts and ideas. Moreover, publication is extremely rapid as books go. Contri- 

 butions will be both by invitation and submission, and no rigid format is prescribed. This 

 is exactly the sort of thing that a rapidly developing area of science needs. For vol.3 the 

 editor particularly seeks contributions on sex determination and differentiation. 



The 17 reviews in the first two volumes, with an average length of 35 pages, concentrate 

 on peri-implantation stages and blastocyst-uterine relationships. Some are more like essays, 

 and many contain interesting new ideas, to which readers are requested to react in subse- 

 quent volumes. Many contributions are by younger scientists. The majority of the authors
