The topic of this symposium was a rather special one. It will appeal parti- 

 cularly to those interested in mammalian reproduction, ovum implantation and 

 early embryology (more particularly the phenomenon designated as "embryonic 

 diapause"). The symposium was held at Rice University, Houston, Texas, in 

 January 1963, and had about 60 speakers and participants. The 19 papers 

 presented range in subject from surveys of delayed implantation in various 

 mammals, through laboratory studies of induced delay of implantation, to 

 studies of implantation as such. Special attention was given to endocrine aspects 

 of implantation. Two papers deal with electron microscopy and biochemistry 

 of implantation respectively. 



The discussions following the papers are also recorded. The book is conclud- 

 ed by a summary of the symposium by E. C. Amoroso. The book is well-printed 

 and adequately illustrated. It has an alphabetical index but lacks a list of 

 participants and an author's index.

25. CELL DIFFERENTIATION 



1963

This volume embodies the papers read at the 17th Symposium of the Society 

 for Experimental Biology, held in Edinburgh in September 1962. The editor 

 states in his preface that the topic of the Symposium "has been one to which 

 zoologists have perhaps paid more attention in recent years than have botanists. 

 Nevertheless, studies on the differentiation of plant cells are progressing rapidly 

 and it was felt that it might be profitable at this stage to give some preference 

 to contributions from this field when arranging the programme." Indeed, of 

 the 20 papers recorded, 9 deal with higher plant tissues, 6 with lower plants and 

 unicellular organisms (Neurospora, slime molds, Acetabularia, Micrasterias, 

 Chlorella, Naegleria), and the remaining 5 with animal cells and tissues 

 (molluscs, amphibians, and vertebrates in general). The papers describe recent 

 work on physiological, biochemical, genetical and uitrastructural aspects of 

 differentiation in single cells, cell groups and tissues, including some studies 

 on cell division and growth regulation. The discussions of the Symposium are 

 not recorded in the book. 



The book is very well printed and illustrated, and includes a large number of 

 photomicrographs and electronmicrographs. It is concluded by author and 

 subject indexes.
