from the classical experimental-morphological angle. 



The book consists of 30 short chapters, ranging in size from 5 to 13 pages. 

 The first 8 chapters deal with gametes, fertilization and cleavage, the next 6 

 with gastrulation, and with mosaic versus regulative development. Then follow 

 5 chapters discussing primary induction, individuation, and morphogenetic 

 potential. The next 3 chapters deal with cyto-differentiation and the role of 

 the nucleus, while the last 8 chapters discuss the phenomena of "reintegration" 

 in later development, comprising such subjects as secondary inductions, or- 

 ganization within the various organ systems, the foetal membranes, endocrine 

 glands, and sex determination. 



Particularly in the first part of the book the author uses numerous untrans- 

 lated German terms, which are not always rendered correctly (the correct form 

 is e.g. "Einsteckversuch", "orts/herkunftsgemass"). The consistent use of 

 "Unterlagerung", meaning "archenteron roof" or "inducing substrate", seems 

 queer. 



Each chapter has a brief bibliography, in which the older literature predom- 

 inates. The book is illustrated with photographs and good original schematic 

 drawings. It has subject and author indexes. The book is definitely too highly 

 priced for students.

This book consists of reprintings of 16 original papers, without further 

 comment, selected by the editor for their particular significance. All papers are 

 concerned with problems of differentiation and morphogenesis; all are in 

 English, and 12 are by American authors. With one exception, they were 

 originally published in easily accessible journals and serial publications (4 in 

 PNAS, 3 in JEZ, the remainder in 9 different journals). 



Three papers date from 1933, '38, and '47 respectively. The remaining ones 

 date from 1950 onwards, with three from 1964 as the most recent ones. The 

 more recent articles penetrate to the level of biochemistry and molecular biology. 



A small collection such as this is of course highly subjective. Any other 

 editor would have compiled a different collection. One thing can be said, 

 however, for the present collection: it represents a wide variety of biological 

 material, ranging from slime molds and algae to the mouse, thus indicating the 

 basic nature of the problems under consideration. 



The original illustrations are reproduced in the reprintings; the reproduction 

 of the photographs is not always good. The table of contents gives only titles, 

 not authors of papers. The source of the second paper is not stated. The 

 original running titles of the articles are reproduced; they lack uniformity and 

 are sometimes completely meaningless.
