given to the exteriorized fetus, placenta, and feto-placental unit, and to the various 

 perfusion techniques and "artificial organs" involved. A final chapter deals with the 

 future potentialities of research on the human fetus and with its social, ethical and legal 



aspects. 



The book is well produced and illustrated with excellent drawings and photographs.

The authors of this book have been working with rabbit embryos for nearly two 

 decades. The book is primarily an extensive survey of their own work and that of their 

 associates, placed against the background of a digest of the literature. The authors' aim 

 has been to give a survey of all basic aspects of mammalian embryology and teratogenesis 

 as illustrated by the rabbit embryo. The literature of rabbit embryology has never been 

 reviewed so extensively before. 



The six major chapters successively discuss (1) early development, (2) embryogenesis, 

 (3) implantation and placentation, (4) organogenesis, (5) protein studies on the rabbit, 

 and (6) the modification of development (teratogenesis in the broad sense). Chapters 4 

 and 5 are largely based on original work, and are therefore not comprehensive. Much 

 factual material has been condensed into tables, particularly in the last chapter, which has 

 extensive tables of teratogenic agents and their effects; this chapter also contains several 

 diagrams summarizing the authors' theoretical concepts of teratogenesis. An appendix 

 presents a brief summary of the phases of rabbit development with reference to the 

 developmental-physiological and genetic viewpoints discussed in the main text. 



The book is illustrated mainly with good photographs. The bibliography contains more 

 than 650 titles up to the beginning of 1973; most of these are in German, English or 

 French. The price of the book is excessive.

This book and its sequel constitute the final outcome of work started more than three 

 decades ago by the late G. L. Streeter. It must be a great satisfaction to the present 

 author to have brought this work to a close. Streeter's and O'Rahilly's aims were to 

 provide a descriptive atlas and bibliography of early human embryology, a formal
