 integration); all papers have English summaries; illustrated with line drawings and photo-

The basic plan of this successful book has remained unaUered, but the contents have 

 been modernized. The morphological approach has been retained, but more attention is 

 devoted to well-documented experimental findings and a minimum of molecular biology 

 is sketched in. The most conspicuous changes are in ch.l (Embryology - its scope, 

 history, and special fields), where the section on fundamental processes and concepts and 

 that on experimental methods have been considerably expanded. 



A number of new illustrations have been added, particularly in Part I (Early develop- 

 mental processes common to vertebrate embryos). The two dozen coloured figures of the 

 second edition are now brought together in a separate section in the middle of the book, 

 and are again reproduced in black and white at their appropriate places in the text. 

 Although this was no doubt dictated by considerations of economy, the duplication 

 involved is no improvement. What is an improvement is the appendix listing the illustra- 

 tions of chick whole mounts, chick sections, and pig embryos separately in developmental 

 sequence. This increases the book's usefulness in the laboratory. The references for 

 collateral reading have been extensively revised and contain many more recent titles. 



The book is printed in a smaller but very readable type. It is well produced at a very 

 reasonable price.
