followed by a bibliography and a group discussion. Much of the research 

 reported on was not published previously. The papers cover morphological, 

 biochemical, endocrinological and pharmacological aspects of ovum implanta- 

 tion in various mammals. The book contains a number of excellent photograph- 

 ical illustrations. 



"STUDIES ON THE STRUCTURE AND DEVELOPMENT 



OF VERTEBRATES'* 



Vol. I and II 



1959 



by E. S. Goodrich Dover Publ. Inc. 



total 906 pp., 754 figs. New York 



(paper bound) Price: 2 vol. $ 5.— 



These two volumes constitute an unaltered reprinting of the original edition 

 of 1930. to which has been added an obituary of the author by A. C. Hardy. 

 Volume I contains the chapters on "hard", volume II those on "soft anatomy". 



The size of the volumes is handy. Notwithstanding the relatively low price, 

 the quality of the paper is good, and the binding firm. The figures are mostly 

 well reproduced.

This conference report consists of 34 papers. At least five of these are of 

 direct embryological significance, but embryologists working on pigment cell 

 formation may want to read many of the other papers, e.g. those on endo- 

 crinology of pigment formation, and on tissue culture, centrifugation, irradiat- 

 ion, histochemistry, growth, metabolism, enzyme activity and electron micros- 

 copy of pigment cells. 



"DEVELOPPEMENT DU COMPLEXE HYPOTHALAMO- 

 HYPOPHYSAIRE CHEZ L'EMBRYON DE POULET" 



1957

This monograph is the report of very thorough study on the development, 

 morphology and histo-physiology of the hypothalamic-hypophyseal complex 

 in the chick, carried out with histological and histochemical methods. 



The work is divided into five parts. The first part deals with the organo- 

 genesis and cytogenesis of the pituitary gland. The second part describes the 

 organogenesis and histogenesis of the neurohypophysis and neighbouring 

 structures. The third part is devoted especially to the development of the 

 vascularization of the hypophysis. The last two parts deal with the develop- 

 ment of neuro-secretory activity respectively in the hypothalamo-hypophyseal 

 complex, and in the ependyma of the 3rd ventricle, particularly in its specific-
