After a brief introduction and an historical survey, three chapters deal with 

 pre-embryonic development, cleavage, and gastrulation. Then follows a brief 

 chapter on organogenesis, highlighting the determination problem, and two 

 chapters discussing the origin of mesenchyme and mesoderm and the origin and 

 significance of metamerism. The next chapter deals with types of ontogenetic 

 cycles, and discusses free-living larval stages, non-larval cycles, and "enclosed" 

 larval stages. Then follows a chapter on ontogenesis viewed as a whole, its sub- 

 division into phases, and evolutionary phase-shifts. The penultimate chapter 

 discusses ,,Umwelt" and ontogenesis (ontogenetic adaptations, changes of 

 ontogenesis by external factors), while the last chapter considers the relation- 

 ships between ontogenesis and phylogenesis. 



The book is profusely illustrated (numerous figures from Russian sources). It 

 has a bibliography of 17 pages (about 40 % Russian titles), and is concluded by 

 a taxonomic listing of taxa cited in the text, and an extensive subject index. 



16 DENTO-FACIAL DEVELOPMENT AND GROWTH 



1967 

 By J. H. Scott Pergamon Press 



Pergamon Series in Dentistry, Vol. 6 Oxford etc. 



217 pp., 74 figs., 6tbs. Price: 63 s.; $ 10.— 



This book will mainly be of interest to dental students and practitioners. How- 

 ever, it is also useful to all those who need basic knowledge of the development, 

 growth, and function of the dento-facial region in man, and, to some extent, in 

 other mammals. To quote from the preface, the book has as one of its aims "to 

 provide the kind of knowledge on which a functional appreciation of the total 

 dental apparatus can be established". Thus it should also be of interest to those 

 working in the field of functional developmental anatomy. 



Three of the five chapters deal with the pre- and postnatal development and 

 growth of the dentition, the cranio-facial skeleton, and the oro-facial musculature 

 respectively. The other two chapters discuss the development and maintenance 

 of bone as a tissue, and the anatomy of cephalometrics. 



The book is illustrated with line drawings and photographs. The latter are 

 usually unlabeled. On the whole the explanatory information contained in the 

 figure legends is very scanty, which leads to unnecessary difficulties for readers 

 not intimately acquainted with the complicated subject. There is a ten-page 

 bibliography and an alphabetical index.
