About two-thirds of the 45 papers date from 1960 or later. A few date back 

 to the late forties and early fifties. The papers have mostly been taken from 

 widely available journals, symposium reports and periodical publications 

 published in English. Among these, the Proceedings of the National Academy 

 of Sciences (10 papers), Science (7 papers), and Developmental Biology (4 

 papers) together have supplied about half of all the papers. Six papers deal 

 specifically with botanical subjects. One paper (by Humphreys, Penman and 

 Bell, on stable polysomes in chick down feathers) is apparently published here 

 for the first time. 



The selection of the papers is in many ways admirable, and the book 

 certainly provides a good first-hand picture of some of the most exciting 

 frontiers of modern developmental biology. 



The book is very well printed, and the original illustrations of the papers are 

 reproduced with admirable clarity. The book unfortunately lacks author and 

 subject indexes. 



Notwithstanding the qualities of this book, some doubt may be expressed as to the justification 

 of books of this sort. The only original part of this book, apart from the paper by Humphreys 

 et a/., are the brief editor's introductions, totaling some 22 pages only. It remains to be seen if 

 •Students and others will be prepared to pay a rather high price for a collection of papers 

 which are for the far greater part easily accessible in or through most University libraries.

This book is based in part on material presented at the International Con- 

 ference on Organogenesis, held in September 1964 in Baltimore, Md. The 

 conference was sponsored by the International Institute of Embryology. The 

 organizers felt that ample attention was being given to-day to molecular 

 biology, and that the time had come to re-emphasize the study of development 

 at higher levels of organization, but with due consideration of the interactions
