This monograph is devoted to the hatching gland of anuran embryos. 

 Alytes obstetricans is the main object, but 12 other German species and 27 

 foreign species were also investigated. The techniques used were those of 

 histology, cytology, and histochemistry. Much use was made of epidermal 

 whole mounts. 



Some additional attention is devoted to other epidermal structures, such as 

 the intercalar gland cells and a simple sense organ (?) of unknown function 

 associated with the nares. 



The work is well illustrated and has a lengthy bibliography and a subject 

 index. It can be ordered separately from the publishers.

It is difficult to say for which category of readers this book is meant. It 

 is certainly not for the specialist in any of the topics covered. On the other 

 hand, the content is sufficiently sophisticated to make the book valuable to 

 all those (general biologists, doctors, students) who want a means of rapid 

 orientation in an increasingly important area of investigation, on a high scien- 

 tific level. A point of particular merit is the broad biological framework of 

 the various discussions, and the inclusion of extensive and modern biblio- 

 graphies in all chapters. 



Of particular interest is the inclusion of a chapter on individual growth 

 patterns in fossils. In all other chapters the human species is placed in the 

 centre, but the broad context is biological rather than medical. All chapters 

 are authoritative and well written. 



The book is well produced and profusely illustrated. It is concluded by a 

 subject index.
