M. LIEBERMAN and T. SANO, eds. 1976. DEVELOPMENTAL AND PHYSIOLOGICAL 



CORRELATES OF CARDIAC MUSCLE

 figs., 28 tabs., subject index. $ 25.00 



This symposium was held in October 1974 in Tokyo. The 48 contributors are from 

 many different countries, the majority from Japan and the United States. The contribu- 

 tions are for the most part brief research reports or surveys of recent research. Most focus 

 on the application of relatively new techniques to embryonic heart muscle cells of birds 

 and mammals, and aU but a few are of interest to developmental biologists. 



The 20 contributions deal successively with electron microscopy of heart cells in vivo 

 and in vitro, with several aspects of membrane permeability and electrophysiology of heart 

 cells, and with physiological correlates of heart muscle. Each contribution is followed by 

 a carefully edited summary of the group discussion succeeding it. 



The book is luxuriously produced and profusely illustrated. The photomicrographs 

 and electron micrographs are of high quality.

"Rudimentation" is a newly coined French word which is unfortunately ambiguous in 

 EngUsh. It refers, not to "rudiments" as used in English, but to rudimentary organs and 

 their origin. This symposium was held in Toulouse m September 1976 and was attended 

 by specialists mainly from France, the United Kingdom and other West-European coun- 

 tries. Most contributions are brief reviews or summaries of recent work. They are either in 

 French or in English and most have a summary in the other language. Most are followed 

 by a brief group discussion. 



Of the 33 main contributions more than two thirds are of interest to embryologists. 

 Ten of these deal with limb development, the others with a variety of other organs in 

 many different vertebrates. Eight papers deal with developmental inhibition due to hor- 

 monal factors, nine with disturbances of morphogenetic mechanisms, and three with 

 chemically induced limb abnormalities. A concluding general discussion has a section on 

 the term "rudimentation" and two contributions on phylogenetic aspects of chick limb 

 development. 



The volume is well produced and illustrated with good line drawings, photographs and 

 light and electron micrographs.
