This book first appeared in America in 1971 and has been quite successful. It is meant 

 for advanced students with a good background in molecular biology, since the emphasis is 

 on differential gene action in development. It was reviewed in Gen. Embryol. Inf. Serv., 

 suppl. to vol. 14, p. 42. 



The second author has translated the book and has taken the opportunity to update 

 and extend it slightly. However, the basic set-up has remained the same. The main 

 improvements are the correction and extension of various figure legends, and the extension 

 of most chapter bibliographies to two or three times their original length. The number of 

 figures has remained the same, though two figures were replaced. The subject index was 

 extended.

The 31st Symposium of the Society for Developmental Biology (U.S.A.) once more 

 hits the bull's eye. It was held in June, 1972. The 13 reviews are all highly informative 

 and clearly set out. It was a good idea to include reviews on genetic control in 

 bacteriophage lambda and T4 development and in sporulating bacteria. Also of interest is 

 a chapter on cell genetics of higher plants. The volume is concluded by a summary of a 

 panel session on social aspects of genetic engineering, consisting of brief statements by 

 four scientists and a theologian. 



The remainder of the contents can be briefly characterized by enumerating the 

 systems dealt with: Drosophila sperm, the Drosophila embryo, Drosophila mosaics 

 (mapping of behaviour), the Mexican axolotl, the early mammalian embryo, the chick 

 oviduct (ovalbumin regulation), the Xenopus genome, and cell heterokaryons and hy- 

 brids. 



The book is produced with the usual exemplary care.

This book IS primarily of interest to clinicians, but parts of it can be of use to 

 mammalian embryologists. These are to be found particularly in Part Two, which is 

 entitled Placental structure and protein hormone secretion, and fetal nutrition. It begins 

 with a review by Laga et al. in which major sections are concerned with the quantitative 

 structure and composition of human placentas and its relationship to placental function.
