G°VAN WAGENEN and M.E.SIMPSON. 1973. POSTNATAL DEVELOPMENT OF THE 

 OVARY IN HOMO SAPIENS AND MACACA MULATTA and Induction of Ovulation in 



the Macaque 



Yale Univ. Press, New Haven, etc. XXII, 306 pp., 122 pis., 12 tabs. $ 27.50, £ 13.75 



This book is a sequel to Embryology of the Ovary and Testis published in 1965 by the 

 same authors. It is essentially an atlas of histology. The descriptive part, which is of most 

 interest to embryologists, occupies about one third of the text pages (4 for the human, 13 

 for the macaque ovary) but about two thirds of the total of 122 plates. The rest of the 

 book is devoted to reports of various experiments, conducted over many years, on the 

 induction of ovulation in the macaque by gonadotropic hormones in various combina- 

 tions. . 



The section on the postnatal development of the human ovary encompasses infancy, 

 childhood, menarche, and the reproductive and postreproductive periods. It has 32 plates. 

 For the macaque, the periods covered are the pre-reproductive phase (subdivided into 

 eight periods of one to several months), the premenarchal and menarchal phases, and the 

 reproductive period (menarche till 25 or 30 years). The number of plates for the macaque 

 is 49, 16 of which give details of the corpus luteum and follicles on various days of the 

 menstrual cycle. There is a brief section comparing ovarian development in man and the 

 macaque, with a comparative table. 



The plates are of excellent quality. Most of them consist of 3-4 micrographs at 

 magnifications ranging from very low to high. The book is magnificently produced at a 

 very reasonable price. It is concluded by a bibliography of 62 titles.

This is a highly interesting and stimulating book. It does not cover a well-established 

 field but its nine reviews by leading investigators describe the momentary state and 

 potentials for the future of an area that is just starting to expand and to yield exciting 

 results. Some of the advantages of arthropods for developmental neurobiological studies 

 are: sensory neurons are situated peripherally and are therefore easily accessible to 

 experimental manipulation; neuron populations are relatively small and single neurons 

 can be identified from one animal to the other; in vitro culture of nervous tissue is 

 remarkably easy. 



Because all contributions are of great interest to all neuro-embryologists we will not 

 review them in detail. Suffice it to say that they are all very readable and remarkably well 

 illustrated. No attempts are made at premature generalization; on the other hand, the 

 great potential of arthropod systems for future work is emphasized. Finally, the book as a 

 whole reflects the renewed interest in supracellular patterns as the counterpart of 

 individual cell function. 



The book is very well produced.
