each originally compiled by one or more contributors. Each table is followed 

 by a list of references. There are 154 such tables in the book, ranging in size 

 from a part of a page to more than 10 pages. The tables are arranged in 13 

 sections, of which the following may be mentioned: Cells and tissues (including 

 e.g. mitotic indices, cell volumes, compensatory hypertrophy, regeneration); 

 Vertebrate reproduction; Invertebrate reproduction; Prenatal vertebrate 

 development; Comparative animal morphology; Environmental factors and 

 growth; Growth regulators and inhibitors. 



There is an extensive alphabetical index which, however, refers to specific 

 organisms only. The table of contents should serve as a subject index. Unfor- 

 tunately an alphabetical subject index is lacking.

16. INTERSEXUALITY 



In Vertebrates including Man 

 1964 



Editors: C. N. Armstrong and A. J. Marshall Acad. Press 



479 pp., 68 figs., 24 tbs. London and New York 



Price: 90 s. 



This collaborative treatise appears very soon after a similar work translated 

 from the German, and issued by the same publishers (Intersexuality, 1963, Ed.: 

 C. Overzier; see G.E.I.S. 10, 1963, p. 308). Whereas in the former book the 

 main emphasis was on the human species, the present book gives equal attention 

 to all vertebrates, including man, and thus will be of greater use to zoologists. 

 There are eleven contributors, four from Great Britain, two from Australia, 

 and five from the U.S.A. 



After a general and historical introduction by A. J. Marshall, the book begins 

 with an exhaustive chapter on chromosome deviations and sex in vertebrates 

 (117 pages plus 10 pages bibliography). This also contains a brief account of 

 normal chromosomes, cell division, gametogenesis and fertilization, and sec- 

 tions on chromosomal mechanisms of sex determination and on methods of 

 identifying the heterogametic and homogametic sexes. This chapter is followed 

 by six chapters dealing respectively with fishes, amphibians, reptiles, birds, 

 mammals in general, and man in particular. The longest chapter is that on 

 fishes (88 pages), the shortest that on reptiles (11 pages). The bibliographies 

 range in size from 2 to 8 pages. In all chapters due attention is devoted to 

 developmental aspects of intersexuality. The final chapter on psychiatric 

 aspects of intersexuality seems a little out of place in a work of this kind. 



The book is well printed and adequately illustrated and is concluded by 

 author and subject indexes.
