This conference was held in West Germany some time during 1976 and was attended 

 •by 14 specialists from various Western-European countries and 11 from North America. 

 The volume contains 20-odd medium-length reviews of recent research, mostly that of 

 the contributors themselves. All of them are in English and all are followed by usually 

 brief discussions. About half of them are of predominantly clinical interest. 



The first ten reviews will be read with interest by all those working on limbs or on 

 organogenesis generally. Among the aspects dealt with are developmental anatomy, histo- 

 chemistry, collagen biochemistry, and various teratogenetic and genetical approaches, all 

 of this in man and various mammals (occasionally chick) and with reference to different 

 developmental periods. 



The book is well produced and profusely illustrated. The numerous photographs and 

 micrographs are well reproduced.

This symposium was held in the U. S. A. in July 1976 and was attended by specialists 

 from North America and various European countries (two groups from Paris). Of the ten 

 short to medium-length, up-to-date reviews two are of exclusively clinical interest, the 

 others are of interest to mammalian and human embryologists and teratologists. 



The subjects covered range from sex determination and differentiation in germ cells, 

 through morphogenesis of various parts of the human genital system, to various endo- 

 crinological aspects. No discussions are recorded. 



The book is well produced and illustrated; most of the photographs and light micro- 

 graphs are well reproduced.
