growth, development of endocrine and nervous co-ordination, and develop- 

 mental aspects of immunity. 



Each chapter is followed by an admirably selected reading list covering 

 both classical and recent work. The book is profusely illustrated. 



13. HEREDITY AND DEVELOPMENT 



1963 



by J. A. Moore Oxford University Press 



245 pp., 83 figs., 2 tbs. New York 



(paper-bound) Price: 16 s. 



Although this book appeared in 1963, it is thought to be of sufficient interest 

 to be reviewed in the present issue. 



The basic plan of the book has been to show how ideas in the fields of 

 embryology and genetics were first formulated and then tested experimentally. 

 To students in these fields it provides a good impression of the gradual devel- 

 opment of scientific theories and of the experimental approaches deduced from 

 them. It must be mentioned, however, that some important recent advances arc 

 totally disregarded. 



The book is in two parts: "The development of genetic concepts" (chapters 

 1-18, occupying about three quarters of the book), and "Embryology" (chapters 

 19-22). 



The chapters 1 through 16 are concerned with classical genetics and have 

 been reprinted almost without change from the author's "Principles of Zool- 

 ogy" (1957). This also applies to chapters 19 through 21, which briefly discuss 

 amphibian development and the problem of differentiation. Of the remaining 

 three chapters. 17 and 18 deal with the structure and function of DNA. the 

 Watson-Crick DNA model, and the various types of RNA. Chapter 22 finally 

 discusses the developmental control of genetic systems. 



Each chapter has its own brief list of suggested reading. The illustrations are 

 adequate, but some of the photographical ones are hardly satisfactory, owing 

 to printing on ordinary paper. 



The reviewer feels that it is highly regrettable that the chapters reprinted from the earlier 

 book have not been brought up-to-date. For instance, a contemporary book of this kind should 

 certainly mention lampbrush chromosomes, and the phenomenon of chromosome puffing, with its 

 important developmental implications. 



1 4. VERTEBRATE EMBRYOLOGY 



1964 



by R. Rugh Harcourt, Brace & World Inc. 



608 pp., 326 figs., 11 tbs. New York — Burlingame 



Price: $ 9.50 



The present text is primarily meant for premedical students. The approach 

 to the subject is unorthodox in that the text is arranged in complete and 

 separate developmental histories — of the frog, the chick, the mouse, the pig, 

 and man. Each of these five chapters begins with a description of the reproduc- 

 tive system of the species concerned, and then proceeds from gametogenesis 

 through fertilization to embryonic and foetal development. 



The book is opened by a short chapter in which the general aspects of 

 embryonic development are stressed, in contrast to the specific traits that
