The aim of this new text is, to quote from the Preface, "to give the future 

 doctor a concise, well illustrated presentation of the essential facts of human 

 development, clarifying the gross anatomical features without omitting the 

 recent advances or changing concepts in the basic sciences". The word 

 "medical" in the title reflects the fact that much attention is given to congenital 

 malformations and their etiology. 



The work is divided into two parts. Part I, entitled "General Embryology", 

 discusses gametogenesis, fertilization, implantation, the bilaminar and tri- 

 laminar germ discs, the embryonic period, and the fetal period. It is concluded 

 by a chapter on congenital malformations and their causes. 



Part II, entitled "Special Embryology", opens with a chapter, on the 

 formation and differentiation of the somite, and then proceeds to discuss the 

 various organ systems, beginning with the skeletal and muscular systems. The 

 cranial and caudal parts of the foregut, the midgut and the hindgut are each 

 treated separately. Face, nose, and palate are treated in a common chapter. 

 The further subdivision of organ systems is conventional. Each chapter ends 

 with a brief description of the most common congenital defects and their 

 etiology, and is followed by a list of references, consisting for a large part 

 of recent titles. 



The many illustrations have all been made by the same artist, and are of 

 admirable clarity and unity of style. The legends are clear. The book is very 

 well printed. It is concluded by an extensive alphabetical index.

 The main body of the present atlas consists of 45 full-page coloured plates 

 representing spatial reconstructions of seven human embryos ranging in 

 length from 3 mm. (about 23 days) to 30 mm (beginning of the third month). 

 Each embryo is represented by a total reconstruction and several (up to 12) 

 partial reconstructions showing the embryo from different angles, and as if 

 partially dissected to show internal structural relationships. The plates are
