them only relate new findings, others are broader and more theoretical in 

 scope, but in all of them the emphasis is on the applicability of comparatively 

 new methods to the study of problems of cell biology in general. The subjects 

 range from the morphological (5) to the biochemical (7) and the biophysical 

 (2) level. Each paper is followed by a bibliography. 



The book is concluded by an author index and a very restricted subject 

 index.

"CYTOLOGY AND EVOLUTION" 



1960 



by E. N. Willmer Academic Press 



440 pp., 174 figs., 12 tabs. New York and London 



This book has been written from a synthetic point of view. It is not con- 

 cerned primarily with the description of observed facts, but with their inter- 

 pretation and integration within a generalized theoretical framework. 



There is no sense in enumerating the titles of the 19 chapters of the book. 

 The author starts from the occurrence of three basic cell types, which are most 

 evident in tissue culture studies, viz.: mechanocytes, epitheliocytes and amoebo- 

 cytes. After a discussion of protozoan organisation in relation to the environ- 

 ment, and of possible basic patterns for simple metazoan organisms (e.g. 

 embryos), the three cell types ultimately serve as a basis for a hypothetical 

 "genealogical tree" of the "families" of cells in the adult metazoan organism. 

 The cell types and families are discussed extensively both from the structural 

 and the physiological viewpoint. The achievement of physiological homoiostasis 

 is recognized as a leading principle. It is further elaborated upon in discussions 

 of the general principles of excretion, body-fluid regulation (also with regard 

 to the demands of the germ cells), hormonal control, and, finally, retinal 

 differentiation. The concluding chapter is called "The concept of evolutionary 

 cytology", and points the way to possibilities of future research in cellular 

 physiology. 



The book is liberally illustrated with drawings and photomicrographs. 

 Each chapter is followed by a bibliography. The work is rounded off by subject 

 and author indexes. 



This is a book not for students, but for advanced zoologists. Among other specialists, 

 embryologists will find in it much that is original and thought-provoking, both from the 

 structural and the functional (physiological) point of view.
