majority wiili the functional, pathological, and physiological aspects of its development 

 aftei birth. However, at least half a dozen arc of potential interest to neuro-embryologists 

 and teratologists, and the discussions following these papers also contain some interesting 



material. 



We just list the following subjects and authors: Developmental biochemistry of the 

 nervous ss stem ( Kretchmer); Nutrition and brain development (McKhann et al); Morpho- 

 physiological development o! brain (Purpura); Nervous maturation in vitro (Crain); Drug 

 effects (Kelsey); Regeneration alter lesions to the fetal septum (DeMyer); Effects of 

 methyl-mercury (Kurland).

II PETERS, ed. 1973. THE DEVELOPMENT AND MATURATION OF THE OVARY 



AND ITS FUNCTIONS 



Excerpta Medica, Amsterdam. Internat. Congress Series No. 267. X,189pp., 89 figs., 

 44 tabs., author and subject indexes. D.fl. 56.-, $ ca. 20.- 



This volume contains the proceedings of an international workshop held in Copen- 

 hagen in July 1972. Of the 24 short research papers six are abstracts or not much more. 

 1 tie papers are arranged in three groups as follows: Regulation of ovarian follicle growth 

 in the immature animal (7 papers); Ultrastructural studies of the immature ovary (6); 

 Maturation of reproductive function (11). 



Group one is mainly endocrinological in character. Group two contains three papers 

 on fetal mammalian ovaries and one on mouse primordial germ cells. Group three deals 

 mainly with postnatal stages; it includes one paper each on amphibians, lampreys 

 (abstract), and voles.

This is the report of an all-American symposium held in Miami, Fla. in February, 

 1973. The 11 papers deal with a variety of cellular and biochemical aspects of CNS 

 development from the embryo to senility, with emphasis on mammals and man but 

 adducing data on other vertebrates as well. Some papers will be almost exclusively of 

 interest to gerontologists and other clinicians. Most of the papers are reviews of recent to 

 very recent work, while only a few consist partially or entirely of previously unpublished 

 work. The discussions are not recorded. 



The book is produced in offset print and adequately illustrated. It has no indexes. 

 Some authors do not indicate clearly whether illustrations are new or taken from other 

 publications.
