"THE BIOLOGICAL ROLE OF RIBONUCLEIC ACIDS"

The three lectures forming this little book deal respectively with "RNA and 

 protein synthesis", "The role of RNA in growth and morphogenesis", and 

 "The role of the cell nucleus in RNA and protein synthesis". The name of 

 the author warrants a thorough, objective, and at the same time stimulating 

 treatment of the subject. The lectures were delivered in April, 1959, at the 

 Weizmann Institute in Rehovoth. The book forms a good source of references 

 for anyone working in this specialized field, as far as the literature prior to 

 1959 is concerned. 



The book is well illustrated and contains a subject index. 



"THE CELL" 

 Vol. Ill, 1961

Editors: J. Brachet and A. E. Mirsky Academic Press 



Vol. Ill: 440 pp., 106 figs., 13 tabs. New York and London

Volume I of this treatise was announced in the eighth full issue, 1959 

 (page 239). In the meantime the subdivision of the subject matter has been 

 altered, and the number of volumes to be published has been increased from 3 

 to 5. Volume I is now succeeded by Volumes HI and IV, the other volumes 

 following later. 



Volume IV and V together will discuss "Specialized cells", while Volume 

 II will deal with "Cells and their component parts". 



Volume III contains only two chapters, one on meiosis, by M. M. Rhoades, 

 and one on mitosis and the physiology of cell division, by D. Mazia. It is 

 particularly the latter chapter, comprising more than 300 pages, which is of 

 significance to developmental biologists. 



Volume IV contains chapters on viruses, bacteria, protozoa, intracellular 

 parasitism and symbiosis, neurons, visual photoreceptors, and muscle cells. 

 None of these chapters is of specific significance to embryologists, although 

 they of course contain a wealth of information. 



"STUDIES ON VERTEBRATE NEUROGENESIS"

This is a full translation of a little-known book published in French in 

 Madrid in 1929. The original book is a compilation of hardly accessible older 

 studies by the author, published originally in Spanish. 



The book consists of six parts, which respectively deal with (1) general 

 histogenesis of the nervous system, and the histological development of (2)
