R. REINBOTH, ed. 1975. INTERSEXUALITY IN THE ANIMAL KINGDOM 



Springer, Berlin, etc. XVI, 449 pp., 221 figs., subject index. DM 97.00, $ 41.80 



This symposium was held in Mainz (West Germany) in July 1974. It brought together 

 57 specialists of whom 48 were Europeans (significantly, more than half of these were 

 French). Their speciaUsations varied greatly and so do the contributions, which are either 

 research reports or reviews. They were edited and if necessary (re)-translated for the 

 book, (though not always optimally, in the interest of rapid pubhcation). 



The 39 contributions are equally divided among the invertebrates and vertebrates. 

 Among the former nine major groups are considered, with the annelids and arthropods 

 predominating. The vertebrates are represented by the five major classes but with nearly 

 half of the papers devoted to the fishes. 



The volume is well produced and profusely illustrated with excellent drawings and 

 photographic material.

This mammoth symposium was held in Cambridge, England in July 1974. It had 

 nearly 200 participants from 22 countries. Of the total of 140 contributions the great 

 majority are brief research reports. At least 30 of them are of potential interest to 

 mammalian embryologists and veterinary obstetricians. 



The papers are grouped in the following main sections: Evolution, The stallion. The 

 non-pregnant mare, The pregnant mare. The fetal and newborn foal. Most of the papers 

 of interest to our readers are to be found in the last two sections. 



The volume is well produced and has excellent photographic plates. There are no 

 indexes.

Masson, Paris. Colloque de la Societe Nationale pour I'Etude de la Sterilite et de la 



Fecondite. X, 137 pp., 39 figs., 7 pis., 5 tabs. F.fr. 78.00, $ 22.10 (paper) 



This is the report of a colloquium held in Paris at an unspecified time in the recent 

 past. Of the nine papers five are brief reviews of recent work which are of interest to 

 mammalian embryologists. 



SzoUosi, and Moricard and Moricard deal with ultrastructural aspects of oocyte 

 maturation and fertilisation (the latter paper is in French). Zaneveld discusses the 

 biochemistry of sperm capacitation. Dukelow and Kuehl, and Soupart deal with in vitro 

 maturation and fertilisation in non-human primates and man, respectively. 



The volume is illustrated mostly with electron micrographs.
