extensive bibliography, which is much easier to use in its present typography. 

 The production of the book is excellent in all respects. 



16. ADVANCES IN MORPHOGENESIS 



Vol.4. 1964 



Editors: M. Abercrombie and J. Brachet Academic Press 



297 pp., 84 figs., 11 tbs. New York — London 



Price: $ 12.— 



This series is now so well known that a detailed review of the 4th volume 

 seems superfluous. Only two of the contributions in this volume will be singled 

 out on account of their great importance in the eyes of the reviewer. 



The first is that by Gurdon entitled "The transplantation of living cell 

 nuclei". The importance of this contribution lies in the fact that the author 

 does not restrict himself to his own and related work on amphibians, but brings 

 together all data available at present on a variety of organisms, such as 

 protozoa, fungi, algae, insects, and amphibians. The data are discussed against 

 the broadest possible background. 



The second contribution to be mentioned specifically is that by Stangc 

 entitled "Regeneration in lower plants". In this instance the importance for the 

 animal embryologist lies in the fact that a means is afforded him to get 

 acquainted with morphogenetic phenomena in organisms much simpler than 

 the higher animals, and possessing morphogenetic correlations which are in 

 part better amenable to experimental analysis. 



For the benefit of the readers the table of contents of vol. 4 is printed below. 



Contents: The transplantation of living cell nuclei (J. B. Gurdon); Morphogenesis in Micras- 

 terias (H. Waris and P. Kallio); Problems in corneal morphogenesis (A. J. Coulombre); 

 Regeneration in lower plants (L. Stange); Regeneration in annelids (H. Herlant-Meewis) ; 

 Biological aspects of the yolk of the hen's egg (R. Bellairs). 



17. MOLECULAR AND CELLULAR ASPECTS OF DEVELOPMENT 



1965 



Editor: E. Bell Harper 6 Row 



525 pp., 400 figs., 59 tbs. New York — Evanston — London 



Price: 81 s. 



This book is of a quite unusual type in that it is essentially a selection of 

 "key papers" published earlier in various media. The editor has used this 

 collection of papers for a first course in developmental biology, but it is not 

 meant to substitute for either descriptive or experimental embryology. Indeed, 

 some background in both is required for the use of the book, which is also 

 meant for graduate students and advanced scientists. 



The 45 papers are arranged in 14 chapters, entitled respectively: cell 

 association, induction, cytodifferentiation and cell division, role of the nucleus, 

 chromosome differentiation, genetic control of differentiation, isozymes, en- 

 zyme regulation, RNA synthesis, synthesis of cell specific products, macro- 

 molecules as the basis of structure, hormones, growth substances, and cell-virus 

 interaction. Each chapter is opened by a brief introduction by the editor (1-2 

 pages). This is not intended as a review of the subject, but rather as a means 

 of summarizing the status of some of the problems and of directing the attention 

 to others. Each of these introductions has its own brief bibliography.
