The preparation of this volume was prompted by the relative lack of information on 

 basic reproductive parameters in primate species frequently used in bio-medical research. 

 The topics selected are those for which comparative data are available and whose nature 

 permits speculation on their possible phylogenetic significance. 



All chapters are authoritative and systematically organized reviews. The book is well 

 produced and the numerous light and electron micrographs are of very good quality.

This monograph illustrates the structure of the organelles of mature spermatozoa and 

 traces their morphogenesis during sperm formation. Most of the illustrations are of 

 mammalian and insect spermatids and sperm. The homologies between the structures seen 

 in them are stressed with a view to presenting as unified a picture as possible. 



Most illustrations are excellent whole- or half-page original electron micrographs. They 

 are supplemented by line drawings and diagrams reproduced from various sources. There 

 is a list of more than 150 references referred to in the text.

A. BOUE and C. THIBAULT, eds. 1974. LES ACCIDENTS CHROMOSOMIQUES DE 

 LA REPRODUCTION (Chromosomal errors in relation to reproductive failure) 

 INSERM (Inst. Natl, de la Sante et de la Rech. Med.), Paris. INSERM Colloques et 

 Seminairesvol. 23.425 pp., 76 figs., 115 tabs. F.fr.50.- , $ 12.- (paper) 



This international symposium was held in Paris in September, 1973. In it took part 

 some 30 scientists from France (15), various other European countries, and North 

 America. The papers are in French or English, and all have summaries in the other 

 language. The discussions following the papers are not recorded. 



The 29 papers are arranged in four groups as follows: I Observations in man (9); II 

 Observations in mammals (4); III Investigations on the mechanism of production of 

 chromosomal anomalies (7); IV Epidemiology in man (9). Sections I and III contain 

 several papers that are of direct interest to mammalian embryologists. Eight pages of 

 closing remarks are provided by Benirschke. 



The book is produced in photo-offset and contains many good photographic plates.
