on cytogenetics and on the causes of congenital abnormalities. The treatment is practical 

 and competent throughout. 



The book is well produced and illustrated with a profusion of good hne drawings and

R. F. GASSER. 1975. ATLAS OF HUMAN EMBRYOS 



Harper & Row, Hagerstown, MD. XII, 318 pp., 130 figs., index of structures. $ 29.95 



This beautiful atlas is a fine teaching aid and reference source. It covers the first eight 

 weeks of development and is based almost entirely on material from the Carnegie 

 Collection. An effort was made to use recent internationally accepted terminology. 



There is one chapter for each week of development (based on a single representative 

 embryo after the third week). Each chapter first outlines the important events, if possible 

 arranged by organ systems, and then presents an extensive series of carefully identified 

 and labelled cross secfions (up to 58 per embryo). The salient features of each section are 

 pointed out in a brief text. 



The photography is excellent and the micrographs are supplemented by very good, 

 instructive hne drawings. The book is luxuriously produced and sturdily bound.

abnormal. 3rd edit. 



WilUams & Wilkins, Baltimore. XII, 421 pp., 312 figs., subject index. $ 12.50 



This text has by now grown so popular that we will restrict ourselves to mentioning 

 the major changes made in this new edition. 



First of all more attention is devoted to clinical aspects, particularly congenital 

 malformations and their etiology. Secondly, new illustrations have been added through- 

 out the book, which now contains many more photographs. Colour has been applied to 

 many of the drawings; the colour illustrations are separately available in the form of 

 35 mm. sUdes. The chapter bibhographies have been extended; some of them are quite 

 long and provide an extremely useful entry into the original Uterature. 



The book is produced with the usual care.
