contributions from eight leading investigators in this field, 

 six French, one Belgian, and one Japanese. The reviews are ex- 

 tensive, well illustrated and up to date, and deal with gonado- 

 genesis, gametogenesis, and gamete maturation in different com- 

 binations, particularly from an endocrinological viewpoint. 



The taxonomic groups considered are the following: hydrozoans 

 (Brien); polychaetes (Durchon); gastropods (Streiff); higher 

 crustaceans (Charniaux-Cotton) ; isopods (Legrand and Juchault); 

 insects, especially Lampyris noctiluca (Naisse); echinoderms, 

 particularly Asteroidea (Kanatani). 



The book provides a good entry into the relevant literature 

 in French and would merit to be translated into English. It is 

 well produced but the price is rather high.

L.ZAMBONI. 1971. FINE MORPHOLOGY OF MAMMALIAN FERTILIZATION 

 Harper & Row, New York, etc. XVI, 224 pp., 99 figs., subject 

 index. $ 15.00, DM 55.50 



In this atlas the author, a pathologist who has been active 

 in this field for years, has attempted to illustrate the most 

 fundamental events of gametogenesis and fertilization in mam- 

 mals and man, from the mitotic division of the spermatogonium 

 and the resting primary oocyte till the first cleavage divi- 

 sion of the embryo. 



The atlas consists of 132 good electron and light micro- 

 graphs, combined into 99 full-page plates; 54 figures are of 

 human, 74 of mouse, and 4 of rabbit material. The story told 

 by the plates is very complete indeed, and considers all the 

 essential normal aspects as well as some findings of rare or 

 pathological occurrence. The appearance of the gametes at all 

 stages during their migration through the male and female gen- 

 ital tracts is illustrated. 



Each plate has an average of about half a page of text, usu- 

 ally with several references. The text is clear and authorita- 

 tive, and frequent cross-references to other plates are pro- 

 vided. The figures are labelled well though perhaps somewhat 

 sparsely. Once an arrow is left unexplained; another arrow 

 mentioned in the text is absent. 



Most of the electron micrographs look rather grey and in 

 some cases there is loss of information through lack of con- 

 trast. It is difficult to judge whether this is due to prepara- 

 tory or photographic techniques or to reproduction. Otherwise 

 the book is beautifully produced at a very reasonable price.

R.A.BEATTY and S .GLUECKSOHN-WAELSCH, eds . 1972. THE GENETICS 



OF THE SPERMATOZOON 



Beatty and Gluecksohn-Waelsch, Edinburgh & New York. 406 pp., 



125 figs. , 55 tabs. 



This book contains the papers read and the discussions held 

 at a Symposium sponsored by the I .S.D.B., held in August, 1971 

 in Edinburgh. The book is not commercially available; a limited 

 number of copies are obtainable on application from the Librar- 

 ian, Department of Genetics, University of Edinburgh, U.K.; the 

 lay-out of the articles suggests that reprints are available 

 from the authors. The Symposium had about 40 participants from 

 all over the world, including five from Eastern-European coun- 

 tries .
