micrographs, so essential to the understanding of a difficult subject like this. It is rather 

 inconvenient that all literature references have been brought together in one bibliography at 

 the end of the book. The subject index is good, but an author index, or at least an index to 

 the contributions to discussions is badly missed.

AN ATLAS OF THE ULTRASTRUCTURE OF HUMAN SKIN, development, differentiation, and 



post-natal features. 1971. By A. S. BREATHNACH 



Churchill, London, 406 pp., 305 figs., subject index. ISBN 7000 1455 1. £ 15.— 



This atlas illustrates the fine-structural features of human skin from a developmental point 

 of view. About half the number of figures illustrate features of fetal skin, and conditions in 

 the fetus serve as a basis for the illustration of more complex post-natal arrangements. A 

 knowledge of the general anatomy of skin at the light-microscopic level is presupposed. 



Most of the more than 300 figures are full- or half-page electron micrographs. A large 

 number of low- and medium-power micrographs are included instead of high-power photo- 

 micrographs. It is questionable whether the latter would not have better served the purpose 

 of bridging the gap between light and electron microscopy. 



The atlas has no text apart from the figure legends, but these are extensive and, as far as 

 possible, are arranged so as to form a continuous story. They contain numerous cross- 

 references. 



On the whole the quality of the electron micrographs and their reproduction is excellent. 

 Some of the highest magnifications seem to be more blurred than is necessary with optimal 

 techniques. The book is produced with great care. Each of the 16 sections is concluded by a 

 brief list of selected references, mainly review articles.
