This booklet is an extensive publication rather than an exhaustive mono- 

 graph. It is concerned mainly with the author's original research on protein 

 metabolism of maternal and embryonic cells and tissues during egg implant- 

 ation, placentation, embryogenesis and organogenesis. The technique used was 

 qualitative and quantitative autoradiography after administration to pregnant 

 rats of tritiated phenylalanine or yeast marked with S^s. The results are 

 grouped in two sections, one dealing with implantation, placentation, and the 

 musculature of the uterus, the other with blastogenesis, embryogenesis, and 

 organogenesis in the fetus. 



Much space is devoted to the critical evaluation and interpretation of the 

 autoradiographs, and to the comparison with data obtained by other authors. 

 Finally, attention is drawn to the significance of the results with regard to the 

 origin of blasto- and embryopathies. 



The book is mainly illustrated with photographs. Many of these are in pairs, 

 one showing an autoradiograph and the other an adjacent stained section. The 

 book is concluded by an extensive bibliography. 



26. THE GROWTH PROCESS IN ANIMALS

In an era in which embryologists focus so much attention on differentiation, 

 a book concerned almost exclusively with growth as a major biological activity, 

 and as the necessary complement of differentiation, must certainly be welcome. 



In this book growth is defined in the broadest possible terms, encompassing 

 in particular the fundamental category of biosynthesis. The author expresses 

 adhesion with J. Z. Young's definition: "Growth is the addition of material to 

 that which is already organized into a living pattern". The author desists from 

 a predominantly mathematical approach, to devote himself to the systematic 

 analysis of growth and growth control in essentially descriptive and qualitative 

 terms. 



The book is essentially a synopsis written for the general biologist and 

 student, and contains a wealth of information. However, it is not a mere com-
