This book is a revised version, under a new title, of a book 

 first published in 1968 and briefly reviewed in Gen.Embryol . Inf . 

 Serv. 1_3, 1969, p. 319. The basic scheme of the book has remained 

 unaltered, but all chapters were revised. The material relating 

 to the chromosomes, originally included under fertilization, is 

 now incorporated in a short new chapter ("Einige allgemeine 

 Prinzipien der Entwicklung" ) together with brief discussions of 

 molecular genetics, the cell cycle, cellular differentiation, 

 and growth. 



Sixteen new figures were added. The reproduction of the photo- 

 graphs is no better than in the first edition, while that of the 

 line drawings is sometimes too dark.

The phrase "clinical embryology" in the title of this book is 

 somewhat odd, but it reflects that the book is a concise, simple 

 account of human development from the clinical point of view. 

 One of its features is that most chapters contain descriptions 

 of the more common congenital anomalies which a practising phy- 

 sician is likely to encounter. 



The book is purely descriptive in character and its organiza- 

 tion is conventional. There are brief separate chapters on mul- 

 tiple pregnancy; growth and development of the fetus; child- 

 birth; changes that take place at birth; and early recognition, 

 incidence, and etiology of congenital malformations. All chap- 

 ters have reference lists for further reading; some are quite 

 extensive; they are useful, though often the most recent impor- 

 tant literature is not included. 



The illustrations are for the most part simple, diagrammatic, 

 but very clear line drawings. The book is well produced; a pa- 

 per-bound edition is also available.

This is the English translation of a successful French text- 

 book, the revised 2nd edition of which appeared in 1968 (see 

 Gen.Embryol. Inf .Serv. 13, 1969, p. 318). It is essentially a 

 graphic atlas consisting of very clear two- and three-dimen- 

 sional diagrammatic drawings supplemented by good photographic 

 material. Colour is used judiciously in almost all drawings, and 

 the whole is didactically very satisfactory. The text is brief 

 and factual. Adequate attention is given to developmental anoma- 

 lies and f oeto-maternal relationships, and aspects of experimen- 

 tal embryology, comparative placentology , and molecular biology 

 are briefly treated. 



The translation is no more than adequate; it is often too lit- 

 eral and there are frequent slips. For instance, the notochord 

 is not "formed from" but isolates itself from the entoderm 

 (p. 23), and on p.4l part of a sentence has dropped out, making
