This monograph is of interest to members of the medical profession only. 

 It is based on many years of personal experience and on a thorough search of 

 the literature. In fact the author states that he reviews almost all of the 

 available literature on the subject. The bibliography contains close to 500 titles. 



The book is well produced and profusely illustrated, and is concluded by 

 a combined author and subject index.

This book contains the 15 papers read at the First International Symposium 

 on Acetabularia held in Brussels and Mol (Belgium) in June 1969. The 

 Symposium was attended by 86 scientists, for the far greater part from Belgium 

 and Western Germany. 



Since its introduction as an experimental organism for the study of nucleo- 

 cytoplasmic interactions in differentiation about 40 years ago, research on 

 Acetabularia has become more and more sophisticated. One of the major 

 focusses still is that of stable mRNA species and their role in morphogenesis. 

 However, the picture has become complicated by the discovery that the chloro- 

 plasts are also engaged in DNA, RNA, and protein synthesis. All this is 

 reflected in the contents of this book. Other aspects considered are nuclear 

 DNA and RNA synthesis, regulation of RNA synthesis and enzyme activity, 

 ultrastructure, photosynthesis, effects of light and gamma radiation, and 

 circadian rhythms. The book is closed by 17 pages of "concluding remarks" by 

 Jean Brachet, which provide a thoughtful summary and perspective of the 

 Symposium. 



The book is produced in offset print. The discussions held at the Symposium 

 are not recorded. The book is profusely illustrated; the many photographs and 

 electron micrographs are very well reproduced. There is a subject index but 

 no author index; although its compilation would no doubt have retarded pu- 

 blication, we feel that its absence considerably reduces the usefulness of the 

 book as a work of reference.
