embryo on the front plane of the stack, as in a wax plate reconstruction. The 

 stack is held in place by two brass rods running through perforations and 

 bent so that the cards can be turned back at will, as in a file. The rods are 

 anchored in a wooden base and the stack is covered by a loose wooden "lid". 



The author states that a prototype of the atlas became very popular with 

 both students and instructors. The atlas has no text, but on "pages" 11 — 19 

 there is a key to external body features, to prominent internal structures (to 

 be used as landmarks), and to the various organ systems and their parts; 

 this key refers to "pages". On the "pages" themselves labeling is restricted 

 to structures that are difficult to interpret or to localize. 



The sections are photographic reproductions of rather poor quality, weak 

 in contrast and showing little more than the minimum detail required to 

 identify structures. The cards are made of rather soft board, and probably 

 will soon get damaged with intensive use. Nevertheless, the atlas can be very 

 useful as a visual aid in the teaching of embryology.

This is a concise text-book of embryology for the use of veterinary 

 students. Its concentrates on domestic mammals and birds, and devotes rela- 

 tively much attention to aspects of reproduction, early development, and 

 placentation that are of practical importance. Comparative and histological 

 aspects are considered only briefly, while teratology has been left out of 

 consideration. 



The organization of the book is conventional. It is illustrated with numerous 

 photographs and pen-drawings. The latter are for the greater part redrawn 

 from varied sources, and are on the whole of good quality. Unfortunately 

 most of the photographs are rather poorly reproduced. The book is concluded 

 by a selective bibliography and a subject index. 



19 LE CERVEAU PRIMITIF 



CHEZ L'EMBRYON HUMAIN DE 34 JOURS 

 1967

(paper-bound) Price: F 10. — 



This little book is the first of a series intended to assist the medical student 

 in understanding the morphology of the human brain and sense organs. The 

 series may also be of use to neurologists and neuroanatomists. 



The book is a picture atlas based on a well-fixed and carefully processed 

 human embryo of 34 days. It presents a wax reconstruction of the brain and 

 13 photographs of exactly symmetrical serial sections through the brain, 

 whose levels are indicated on the wax model. Four other photographs supply
