book is considerably reduced, at least for countries outside the U.S.A. 

 A disadvantage is that the quality of the photographic illustrations has suf- 

 fered. They are on the whole much more smudgy than the original ones, 

 which had been reproduced with the utmost care. Otherwise the production 

 of the book is quite satisfactory. 



8 MODERN EMBRYOLOGY 



1968 

 By C. W. Bodemer Holt, Rinehart & Winston, Inc. 



475 pp., 327 fiqs., 3 tbs. New York - London 



Price: $ 9.95; 95 s. 



This text-book is essentially an elaborated version of L. G. Barth's "Em- 

 bryology" (2nd edition, 1953), but seen from another point of view it is 

 an entirely new book. The text has been rewritten almost entirely, although 

 occasionally and original paragraph is recognizable. The basic plan of the 

 book has remained unaltered, but a wealth of new material has been smoothly 

 integrated into the old text, while some of the old material has been con- 

 siderably reshuffled, and an entirely new chapter on nucleo-cytoplasmic inter- 

 actions added. The new book thus truly reflects the advances made during 

 the last 15 years. 



For those who have never used Barth's book, a quotation from the present 

 book's preface may clarify its nature: 



"Modern Embryology is designed as a brief introduction to the general principles of 

 embryology and a survey of developmental anatomy and physiology. In its preparation 

 the guiding policy has been to present without excessive embroidery the factual and 

 theoretical material necessary for an understanding of embryonic development and an 

 appreciation of developmental biology. It is intentionally not encyclopedic in character, 

 although the advanced student may find it useful as a survey of developmental processes." 



One of the differences with Barth's book is the inclusion of brief lists of 

 selected readings at the end of each chapter, and of a fairly extensive 

 bibliography at the end of the book. Although in itself this is well-balanced, 

 it is a pity that no references are made to it in the text, particularly since 

 the use of authors' names in the text is rather inconsistent. 



A major feature of the book are its illustrations. Most of the figures from 

 Barth's book were redrawn, but whereas the old figures were sometimes 

 characterized by a certain crudity, the new versions are both didactically 

 and esthetically highly satisfactory. The use of various shades of colour has 

 contributed greatly to this end. Moreover, more than 80 new photographs 

 were included, and these are beautifully reproduced. Another good feature 

 of the book is a well-balanced glossary of anatomical, embryological, and 

 general biological terms, prepared by Dr. Dorothea Rudnick. Printing and 

 lay-out of the book are modern in the best sense of the word. 



9 ENTWICKLUNGSPHYSIOLOGIE 



1967 



By J. D. Ebert Bayer. Landwirtschaftsverlag 



Serie Moderne Biologie Miinchen - Basel - Wien

This is the German translation of one of the best brief introductions to 

 developmental physiology available ("Interacting systems in development"). 

 The original book appeared in 1965, and thus is still largely up to date. It 

 has been received very well (for a brief review see Gen. Embryol. Inf. Serv.
