10 mm. frog larva (Rana pipiens, sections); IV. Development of the chick 

 embryo (up to 72 hours, whole mounts and sections); V. Development in the 

 pig embryo (10 mm., sections) and fetus (dissection). 



The book is essentially a guide for laboratory exercises, but it also contains 

 24 sections and tables in small print summarizing or discussing general topics. 

 Lists of review questions are interspersed throughout the book. The illustra- 

 tions consist of very clear drawings, mostly based on sections, and clearly 

 labelled. There is a short bibliography of books and an alphabetical index.

This book is written in Russian. It consists of two parts, one dealing with the 

 embryology, and one with the histology of the oral cavity and the teeth. The 

 first part consists of four chapters, viz. 1 ) Development of the oral cavity and 

 the face; 2) Development and growth of the milk teeth; 3) The dentition of the 

 milk teeth; Dentition theories; 4) Development and dentition of the permanent 

 teeth. 



The bibliography contains 81 Russian titles (35 of which date from the last 

 decade), and 135 titles in other languages. 



11. AN ATLAS OF EMBRYOLOGY 



1963 



by W. H. Freeman and B. Bracegirdle Heinemann 



98 pp., 67 pis. London, Melbourne, Toronto 



Price: 18 s. 



This atlas is intended to help beginning students to overcome difficulties in 

 interpreting embryological structures seen under the microscope. The atlas 

 consists of 67 plates, 26 illustrating frog development, and 41 illustrating chick 

 development. Frog development is illustrated with sections only, while twelve 

 of the plates relating to the chick represent whole embryos. The majority of the 

 sections depicted are transverse ones. Each plate consists of a photograph of 

 the section or embryo, accompanied by a very carefully executed line drawing 

 of the same object, which is fully and clearly labelled. Wherever necessary the 

 plane of sectioning is indicated in a small figure of the whole embryo. 



The quality of the sections used is not always excellent, but the authors feel 

 that this is no great drawback, since students are often required to interpret 

 rather poor-quality slides and must learn to recognise artifacts. The quality of 

 the photographs of whole chick embryos is very good. 



A rather concise reference table of chick development is printed on the end- 

 papers of the book. The atlas has no further text.
