 embryos of marine invertebrates 



This collaborative work is due to the efforts of no less than 58 contributors, for 

 the far greater part United States scientists, who have provided the 51 chapters 

 listed above. Author's names have been omitted for brevity in this listing, but it 

 may be said that the authors are all outstanding specialists in their fields. It is a 

 major achievement on the part of the editors not only to have secured the 

 collaboration of such a representative group of authors, but also to have induced 

 them to maintain a considerable uniformity of style and coverage. 



The book is a mine of information for almost all developmental biologists, but 

 particularly for those institutions where modern research in developmental 

 biology is planned or is just being started. 



The chapters are all clearly organized and have extensive bibliographies; the 

 reader is referred to literature pertaining to methods not fully treated in the text, 

 or to alternative methods; the pro's and con's of different methods and species 

 are discussed; frequently addresses are given where specific material may be 

 obtained; numerous formulae are provided of media, saline solutions etc. Some 

 chapters describe techniques never published before, and the ones describing 

 published methods provide more details and "tricks of the trade" than is usual in 

 journal articles. In order to avoid duplication, techniques that have recently 

 been treated extensively in books were omitted. 



In a book of this kind the illustrations are of the utmost importance, and the 

 ones in this book are very good indeed. The book's lay-out and printing are 

 excellent. It is concluded by a detailed subject index. A few authors' names are 

 included in this index in what seems a haphazard manner, and the purpose of 

 this is not clear.

Whereas previous volumes of this excellent series reviewed in this periodical 

 were based on symposia, this appears not to be the case for the present volume. 

 It seems to be a more or less fortuitous collection of research papers which only 

 have in common that they all deal with ontogenetic aspects. 



The first three papers deal with the isocortex and the somesthetic cortex of the 

 sheep fetus (one is by Astrom, one by a group of workers from the Karolinska 

 Institute, and one by Molliver). Then follows a paper on the electron microscopy 

 of the developing chick brain (by Wechsler and Meller). The remainder of the 

 book is taken up by a series of four papers dealing with correlations between 

 structural organization, functional activity, and biochemical properties of the
