between the various classical and modern levels of investigation. Consequently, 

 the problems of organogenesis are treated in this book in an integrated and 

 comprehensive manner. The book has a much wider scope than the usual 

 Symposium report; it has almost the character of a collaborative treatise, and 

 is equally useful to investigators and to advanced students. This is also reflect- 

 ed in the considerable length of the bibliographies of many chapters. 



Nearly half of the 31 chapters were specially written for this book and are 

 not based on material presented at the Conference. It is particularly the section 

 on the viscera (see below) that was extended far beyond the scope of the 

 Conference by the inclusion of chapters on the heart, the liver, the lungs, the 

 thyroid, the endocrine pancreas, and the kidney. 



The editors are to be congratulated, not only on having produced a well- 

 balanced book, but also on its unusually rapid publication. 



The book is organized in six sections, the first of which consists of three 

 chapters on basic mechanisms ("Genes and development" by Ursprung, "Inter- 

 cellular adhesion and histogenesis" by Mercer, and "Mechanisms of morpho- 

 genetic movements" by Trinkaus). The other sections deal with specific 

 organs and organ systems, to wit: the nervous system (including the eye; 6 

 chapters), the limb (5 chapters), the skin (1 chapter), the viscera (including 

 several endocrine and lymphatic organs; 7 chapters), and the reproductive 

 system. The last section is subdivided into two parts, one dealing with sex 

 differentiation (7 chapters), and one with the placenta (2 chapters). 



The book is beautifully produced and the numerous illustrations are of the 

 highest quality, and clearly and extensively labeled. The book is concluded by 

 a subject index. 



The book could have been made more valuable as a work of refercne by the inclusion of 

 an author index, although it is realized that this would have delayed publication. Another 

 minor criticism concerns the lay-out of the bibliographies; it is difficult to find specific 

 authors' names, since they are not capitalized and do not project from the margin of the 

 column. Also, though perhaps not preferable for aesthetic reasons, capitalization of authors' 

 names in the text would have made the use of the book as a reference work easier. The 

 numerical reference systems as such is a definite improvement, and is commendable for other 

 books.
