of these visible elements among Darlington's so called "undefined residues 

 of heredity ". 



This monograph which does not pretend to be a treatise or to give an 

 exhaustive survey of the literature, is very clearly written and illustrated with 

 very suggestive figures and highly worth to be read by biologists in general.

..REGENERATION AND WOUND-HEALING" 

 1952 



by A. E. Needham Methuen & Co Ltd 



152 pp. with 5 figs and 3 tabs London 



price: 8s. 6d 



This small size book, forming one number in the series of monographs on 

 biological subjects will only give a short illustrative introduction to this very 

 extensive field of science which fascinated man already for many centuries. 

 It will moreover form a key to the rich literature on this subject and will 

 give a survey of the recent advances in its various aspects. 



After a short sketch of the normal sequence of events in regeneration, much 

 attention has been paid to the metabohc events during regeneration and to 

 the causal analysis of regeneration, two aspects on which many advances 

 have been made during the last decades. 



After some smaller chapters on the rate of regeneration and on morphallaxis 

 and related types of regeneration, finally the distribution of powers of 

 regeneration in the animal kingdom has been briefly reviewed and its many- 

 sided significance has been extensively discussed. The clearly written text 

 and the very rich bibliographical data — there are more than 650 references 

 quoted — makes this book to a very practical and convenient guide into the 

 field of regeneration not only for school teachers but just as well for scientists. 

 A larger number of illustrations would have undoubtedly improved the read- 

 ableness of the text, but would of course also have advanced the price of 

 this booklet.

The author states in his preface that this textbook is for the beginner, so 

 that it is not intended for a reference book since many details are intentionally 

 lacking. This concise textbook which covers the histology and microscopic 

 anatomy of the mammalian body, including man, is successfully used at the 

 medical school in Philadelphia where medical education is. however, emphati- 

 cally based upon direct contact with demonstration material in form of micro- 

 scopic specimens and motion pictures. Much attention has. therefore, been 

 paid in this textbook to the illustrations. These form indeed one of the most 

 valuable aspects of this in several respects very elementary book.
