Although this collection of technical reviews was written largely by doc- 

 tors for doctors, its comparative approach makes it useful for mammalian 

 embryologists interested in the fetal stages. All authors but one are British. 

 They consider many different species alongside the human. 



Perhaps of most universal interest are the first two chapters on struc- 

 tural-functional correlations in the placenta. Chapters 3-6 deal with mater- 

 nal, fetal and placental blood flow and with physiological adaptation to di- 

 minished placental transfer. The remaining 9 chapters deal with various 

 classes of substances and with some strictly clinical subjects. 



Most chapter bibliographies run into 1976 or '77. The volume is adequately 

 illustrated.
