the nature of the genetic background, and the principle of inbreeding. 



The next four chapters discuss systemic disorders of the skeleton, i.e. 

 disorders characterized by the widespread distribution of effects within the 

 membranous, cartilaginous and osseous skeleton respectively. 



Then follow six chapters on localized disorders, respectively of notochord, 

 paraxial mesoderm, segmentation, sclerotome differentiation, and the appendic- 

 ular skeleton. The last two chapters of the special part deal with minor 

 skeletal variations. 



The brief concluding chapter is entitled "General considerations" and 

 constitutes a synopsis of developmental genetics mainly in relation to skeletal 

 anomalies. It also includes a section on experimental teratology and its 

 genetical aspects. 



The numerous illustrations, partly original, partly from various other 

 sources, are clear and well reproduced. The 9 full-page plates present photo- 

 grafic material. The printing of the book is excellent. It is concluded by an 

 extensive bibliography and by author and subject indexes. 



12. CELL GROWTH AND CELL DIVISION 



1963 



Editor: R. J. C. Harris Academic Press 



(Symp. Internat. Soc. for Cell Biol., Vol. 2) New York and London 



341 pp., 121 figs., 17 tabs., 8 pis. Price: $ 13.— 



This book is the second volume of a new serial publication consisting of 

 reports of the annual symposia organized by the International Society for Cell 

 Biology. The present Symposium was held in Liege, Belgium, in May 1963. 



The volume contains 19 papers, 15 of which are written in English and 4 

 in French; the latter have an English summary. Original cytological and bio- 

 chemical research is reported on cell division and cell growth in a variety of 

 organisms, ranging from unicellular organisms and plants via invertebrate 

 eggs, to vertebrate cells in culture. Attention is also focussed on the problem 

 of amitosis. 



The well-printed and well-illustrated book is concluded by an author index.
