authors, but this being as it is, it is to be regretted that the book has been given its present 

 title. For, even if the word "development" in the title is taken to indicate also the physical, 

 emotional, social, intellectual and spiritual changes occurring throughout the life span, one 

 would have expected at least also a coherent account of man's phylogenetic development, 

 an aspect which is lacking almost entirely. 



"HANDBOOK OF CELL AND ORGAN CULTURE"

The present book is a laboratory guide which has grown from a course given 

 to students at the University of Michigan since 1953. It consists almost entirely 

 of concise descriptions of techniques and procedures, presented partly in the 

 form of laboratory exercises. Key references are given for each field of 

 investigation. There are no illustrations. 



"A GUIDE TO THE STUDY OF DEVELOPMENT" 



1960 

 by W. W. Newby W. B. Saunders Company 



217 pp., 79 figs. Philadelphia, London 



Essentially, this is a laboratory guide for the study of descriptive embry- 

 ology, based on the chick and the pig. However, the laboratory exercises 

 alternate with chapters on the physiology of development, which also include 

 many data on other animal forms. These chapters contain descriptions of 

 experiments with various egg types, which may be performed as demonstrations. 



The laboratory exercises are very sparsely illustrated. On the other hand, 

 the general chapters and those on the physiology of development are illustrated 

 with numerous line drawings of very good quahty. 



There are very useful chapters on abnormal development and twinning, and 

 on embryology and evolution. No literature references are given. The book is 

 concluded by a subject index. 



The book is printed in photo-offset, and paper-bound.

 The first edition of this book appeared in 1955. This is a revised edition. 

 The book has been written for first-year dentistry students. Its main organi- 

 zation is in three sections, viz. embryonic development of the face and oral 

 cavity (9 pages), oral histology (with an introduction to general histology; 77 

 pages), and tooth development, eruption and shedding (17 pages). 



The book contains good photographs, but most of the drawings are done 

 by a rather primitive technique. Particularly in the very elementary first
