A.G.HENDRICKX. 1971. EMBRYOLOGY OF THE BABOON 



Univ. of Chicago Press, Chicago, etc. X,205 pp., 139 figs., 



13 tabs., subject index. $ 15.00, £ 6.75 



This book is the first monograph in primate embryology ever 

 published. The main body is a series of external and internal 

 descriptions of 23 embryonic stages which strictly parallel 

 Streeter's developmental Horizons for human embryos. This great- 

 ly enhances its value for comparative studies. Moreover, the ba- 

 boon material of the younger stages, particularly stages IV 

 through IX, is much more complete than the human material avail- 

 able at present. 



Apart from the main stage descriptions there are separate 

 chapters on the reproduction of the baboon and on the placenta. 

 The fetal stages are not treated extensively, but much useful 

 Information on fetal growth and organogenesis is brought togeth- 

 er in the form of tables and graphs in an appendix. 



The numerous photomicrographs of sections are well reproduced, 

 and some good drawings based on serial sections and reconstruc- 

 tions are included. The gross photographs, so important in a 

 book of this kind, are not so satisfactory: often details men- 

 tioned in the captions cannot be discerned. It would seem that 

 the lighting conditions during photography were often sub-opti- 

 mal. Drawings, particularly of the early stages, would have been 

 more appropriate.

This is the report of a multi-disciplinary Symposium held in 

 Venice in April 1970. It was attended by more than 230 scien- 

 tists from all over the world. The book is packed with interest- 

 ing and well-presented information. Most papers report on recent 

 original research, and in addition many contain varying amounts 

 of review material. The discussions following the papers are re- 

 corded in full and have their own literature references.
