By the time this review appears this monograph will have been completed three years 

 ago, which is a long time in a rapidly moving field like this. Yet we may safely say that 

 it will long remain a firm foundation to build on for those who are entering the field, as 

 well as a great help for all mammalian embryologists. 



The subject matter is subdivided into 1 1 short, readable chapters. Two of these deal 

 primarily with experimental-embryological aspects, five with developmental genetics. The 

 last of these is entitled Chimaeras versus mosaics. A separate chapter thoughtfully and 

 critically discusses the distribution of cell populations in the embryo, in other words, the 

 problem of "clones and patches". 



The book is beautifully produced and well illustrated. The 14-page bibliography ends 

 in 1974, with the exception of the pubUcations of the author and her associates. Three 

 important papers published in 1975 have been added in proof. The subject index could 

 have been longer; particularly unfortunate is the omission of "determination" and "allo- 

 cation".

The author of this exhaustive monograph has previously written two similar, though 

 shorter works, one on the insect head (1965) and one on the thorax (1970). In the pre- 

 sent work, however, more stress is placed on developmental aspects. Part I, which occupies 

 48 pages and discusses these aspects in a general way, is not restricted to the abdomen nor 

 indeed to insects. It deals with various aspects of heterochrony and with substitution, 

 homology and analogy of organs on the basis of the modern literature. It is odd that 

 heteromorphosis or homeosis, for which some recent authors have suggested important 

 roles in evolution, is not even mentioned in passing. 



Part II (60 pp.) ueals mamiy wim general aspects of abdominal segmentation, abdo- 

 minal appendages, and external and internal genitalia. Finally, Part III covers the available 

 data in the individual orders. In most orders some attention is devoted to *he origin of the
