Volume I has an Introduction by J. Brachet on the history of chemical 

 embryology, and is further organized in three parts, viz. 1 ) Biochemistry of 

 germ cells and fertilization (chapters by Williams and Monroy), 2) Bio- 

 chemical patterns in embryos (chapters by Gustafson, Collier, and Deuchar), 

 and 3) General biochemistry of development (chapters by Moog, Solomon, 

 Staehelin, and Grant). The third part discusses selective aspects of the 

 ontogeny of enzymatic and non-enzymatic proteins, including the problem of 

 information transfer in development. 



The book is well-produced. It is concluded by extensive author and subject 

 indexes. 



Volume II will have the subtitle "Biochemical control mechanisms and 

 adaptations in development".

This book embodies the papers read at the 24th Symposium of the series 

 known so far as the "Growth Symposia". Now that the "Society for the 

 Study of Development and Growth", which sponsors these Symposia, has 

 changed its name into" Society for Developmental Biology", the Symposia are 

 perhaps more properly designated as "Developmental Biology Symposia". The 

 24th Symposium was held in Carleton, Minnesota, in June 1965. All par- 

 ticipants except one came from the U.S.A.. 



The papers are arranged in three sections, entitled "Reproduction at the 

 molecular level" (4 papers), "Reproduction of subcellular systems" (4 papers), 

 and "The reproduction of cells" (3 papers). 



The book is opened by a theoretical introduction to the subject by Herbert 

 Stern, which at the same time serves as a summary of the Symposium. 



The first two sections will be of particular interest to molecular biologists 

 and geneticists. They contain discussions of such subjects as gene action, anti- 

 body specificity, virus-host interaction, chromosome reproduction, and extra- 

 chromosomal heredity. The third section contains two papers which are of 

 specific interest to embryologists, viz. "Haploidy and diploidy in the repro- 

 duction of cell type", by W. Tulecke, and "Cell and tissue interactions in the 

 reproduction of cell type", by I. R. Konigsberg and S. D. Hauschka. Among 

 other things, both papers consider the problem of differentiation, but from 

 entirely different angles. The former paper draws predominantly on evidence 

 from plant tissues, whereas the latter deals exclusively with vertebrate em- 

 bryonic cells, particularly myoblasts. The third paper of this section is by 

 R. R. Kohn and deals with cellular and organismic factors in processes of
