Attention was focussed on late prenatal and early postnatal mammalian development. The 

 preimplantation period and the period of organogenesis were largely excluded, and studies on 

 non-mammalian systems were included only insofar as they yielded information considered to 

 be of fundamental importance. 



The 78 papers read at the Symposium are grouped in seven sessions as follows: 1) Cross- 

 placental transfer of radionuclides (13 papers); 2) Radionuclide metabolism by the neonate 

 (6); 3) Radiation effects — fetal (13); 4) Radiation effects — perinatal (21); 5) Irradiation of 

 perinatal human populations (6); 6) Radiation effects — CNS (11); 7) Mechanisms of differential 

 radiosensitivity (8). Particularly sessions 1, 3, 6, and 7 contain many papers that are of 

 interest to developmental biologists. Most papers are followed by brief discussions. Several 

 sessions are concluded by chairman's remarks. There is a lengthy Symposium prologue by T. R. 

 Noonan and an epilogue by M. R. Sikov. 



The book is well printed and adequately illustrated. The list of participants contains only 

 those members not presenting papers. The absence of an author index is badly felt. The paper 

 cover is insufficient for a book of this size; publication in two volumes would have been better. 

 The price of the book is surprisingly low. It is available as CONF-690501 from Clearinghouse 

 for Federal Scientific and Technical Information, National Bureau of Standards, U.S. Depart- 

 ment of Commerce, Springfield, Virginia 22151, U.S.A.

FOETAL AND NEONATAL PATHOLOGY. Third edition. 1970. By J. E. MORISON 



Butterworths, London. 655 pp., 152 figs., 18 tabs., subject index. ISBN 407 17601 2. £ 11.— 



The second edition of this book appeared in 1963 and was reviewed in General Embryological 

 Information Service, Supplement 10, 1964. The book is not intended as a compilation but as 

 an approach to perinatal disease which integrates basic biological thought with clinical 

 practice. The present edition is about 100 pages longer than the second and many parts have 

 been rewritten. The subdivision into chapters has remained unaltered. 



The book is now so well known that it may suffice to list the major additions. These 

 concern the following topics: chromosomes in foetal malformation and abortion; developmental 

 immunology and immunology of the placenta; infarct-like placental lesions; the assessment 

 and significance of intra-uterine growth retardation; respiration and resuscitation, and finally 

 rubella infection. 



The number of illustrations, particularly of original photographs, has been extended. The 

 chapter bibliographies have been revised and updated; many of the older titles have been 

 replaced by newer and more accessible ones. Finally, the subject index has been considerably 

 expanded.

Although much of the subject matter of this collaborative treatise is peripheral to 

 developmental biology, several of the chapters devote attention to problems of morphogenesis 

 and cellular differentiation in connection with the main subject. We will restrict ourselves 

 mainly to mentioning these chapters. 



A brief chapter by D. J. Lehmiller outlines the techniques available for studying cellular 

 and molecular renewal. The chapter by I. L. Cameron on cell proliferation and renewal in the 

 mammalian body is of interest mainly because of its classification of cell populations based 

 on proliferative behaviour, and its section on the control of proliferation. Two chapters by
