the large amount of recent Russian literature cited. Each of the 

 three sections has an extensive bibliography In which about half 

 of the titles Is In Russian (title translations are provided). 

 The translation Is good. The book Is Illustrated mainly with 

 good line drawings from various sources.

The author assembled this collection of facsimile reprlntlngs 

 of original articles primarily to emphasize the need for reinte- 

 gration of the results of basic and applied biology. We review 

 It here because It contains much of his thought on cellular and 

 developmental biology and on the development of the nervous sys- 

 tem, which was so far scattered through the literature and there- 

 fore often not, or no longer easily accessible. 



The 35 papers are grouped Into five sections as follows: I. 

 Biographical (3 papers); II. Biomedical education (4); III. The 

 living cell and the cell community (11); IV. The living nerve 

 cell and the nervous system (6); V. Nerve regeneration and nerve 

 repair (11). Sections III and IV are of the most Immediate In- 

 terest to our readers; six papers In the former, and one In the 

 latter are also to be found In an earlier compilation of papers 

 by Weiss ("Dynamics of development", 1968). Three of the papers 

 In these sections bear no year of publication, the others date 

 from 1949 till 1969. Section V Is mainly of Interest to neuro- 

 surgeons; It contains much of the pioneer work on nerve regener- 

 ation carried out by Weiss and his collaborators In the 'four- 

 ties . 



The papers are grouped In logical rather than chronological 

 order, and their continuous reading Is facilitated by brief In- 

 terconnecting paragraphs, which emphasize the author's Integra- 

 tive, blo-medlcal point of view.
