Scientists were asked to state their name, degree(s), address, and research subjects in so far as recent, unpublished work in developmental biology was concerned. Complete entries (with research subjects) are entirely based on the data sheets. Subjects identical to those in vol. 16 were confirmed by the scientists still to be correct. Entries without research subjects: a. Persons listed on the sheets as being engaged in research in developmental biology, without further specification of subjects. b. Persons with a complete entry in vol. 16 who have not returned their sheets. Name, degrees, and addresses were reprinted unchanged from vol. 16 and may be partially out of date. c. Emeritus professors no longer active in research. d. Some persons who have not returned data sheets for two or more volumes have been listed nevertheless; cases in point are several I.S.D.B. members. e. Persons listed in vol. 16 whose death has come to our attention (marked f). Persons Hsted in vol. 16 but not in vol. 17: a. Persons who had research subjects in vol. 16 but are no longer engaged in research in developmental biology. b. Persons who had no research subjects in vol. 16 and have not returned the sheets for both vol. 16 and 17. The abbreviation Ms. in names stands for Miss or Mrs. ABBOTT, Ms. U.

Within each of these categories an alphabetical order is maintained. The Directory does not give Institute addresses . These can be found by looking up the name of one of the Institute members in the Directory of Names and Addresses. Names of Institute members who are not explicitly engaged in developmental biology are as rule not listed, with the exception of the names of Institute directors. (x) Crosses indicate those- Institute members who appear in the Directory of Names and Addresses with one or more research subjects. If all members of an Institute lack crosses, this usually means that no information has been submitted by the Institute in 1978. Older information concerning such Insti- tutes may be found in previous issues.

These are the first two instalments of a gigantic treatise whose concep- tion could probably only have occurred in Germany. The preparations for it must have started at least a decade ago and the ultimate aim is to produce a modern replacement for the classical treatises by Korschelt and Heider, Hertwig, and Schleip (1890-1929) . The treatise will appear in separately available monographs which will cover 22 metazoan groups in two series: I, Descriptive Morphogenesis and II, Causal Morphogenesis, so that the ul- timate number of volumes may be close to 40. The number of German, Austrian and Swiss authors will probably exceed 40. Judging by the two first volumes this will be a work in the best German tradition: thorough, well organised and meticulously illustrated. The first volume opens with a 57-page chapter by the editor which lays the theoretical foundations for the whole work in the form of a general discussion of morpho- genetic methods ("pure", evolutionary and causal morphology) and of the con- cepts used in the study of morphogenesis. The remainder of vol.1 is taken up by Tardent's treatment of the descrip- tive morphogenesis of the Cnidaria. The second volume, by Fioroni, is de- voted to the descriptive morphogenesis of the Cephalopoda. Both contribu- tions also devote considerable attention to systematics, reproductive biol- ogy and rearing methods and, in the case of the Cnidaria, asexual reproduc- tion and ageing. The books are well printed and bound and illustrated with a profusion of excellent line drawings, half-tones and photographs, most of which are orig- inal. The literature in the extensive bibliographies runs into 1975/76. Textbooks 2. J.W.BROOKBANK. 1978.

Historical perspectives, current principles, and future directions This text was written for use in undergraduate courses. The book is unusual in that it is built around a series of chapters each dealing with a particu- lar system (chs.2-8), rather than proceeding from early to late events in all systems. Each user must decide for himself whether he likes this idea. Chap- ters 1 (43 pp.) and 9 (12 pp.) serve to integrate the book by concentrating on aspects and theories common to all systems. These chapters on the whole fulfil their role admirably and provide real insight. Ch.l deals briefly with the principles of cellular and molecular biology, asexual reproduction and growth, sexual reproduction, and embryonic develop- ment in animals and plants. Each of the chapters 2-5 deals sequentially with normal development (from gametogenesis to adult) , classical and modern ex- perimental approaches, and gene activity at the molecular level. Noteworthy features are sections on specification of synapses in ch.4, and on terato- genesis, the development of immunity, and the development of behaviour in ch.5. Chapters 4 and 5 have appendices to help in understanding developmental anatomy in the laboratory. In the chapters 2-8 comparisons between systems are made wherever appropriate. The book is on the whole very readable but in places somewhat cryptic or perhaps too difficult and condensed for beginning students. There are occa- sional inaccuracies, sometimes apparently due to unfamiliarity with the re- cent literature. This reviewer rather missed a discussion of lens regenera- tion in urodeles, a paradigm of cell transformation. He also found the defi- nition of "field" unsatisfactory and that of "morphogenesis" rather inade- quate; no proper definition of "positional information" is given. All chapters have adequate reading lists, but since author names are hard- ly ever mentioned in the text it must sometimes be difficult for the student to know what to select. The book is very well illustrated with line drawings and a wealth of photographic material, much of it specially prepared for the book. The explanatory captions are extensive but a few are less than adequate (fig. 5. 29 refers to amphibian limb regeneration, not to the mammalian limb bud!) 3. P.GRANT. 1978.

This is one of the best developmental biology texts to have appeared in recent years. It was designed for older undergraduates and beginning gradu- ates and the scope and coverage are astounding. Any student who has digested it will have a firm grasp of the entire field. It was an excellent idea to start the book with the principles of cell biology with particular refer- ence to the flow of information in the cell. Another noteworthy feature is the emphasis throughout on the hierarchial nature of biological organisation. 189 I -The selection of areas to be treated is on the whole admirable. In most areas the treatment is surprisingly up to date, though in some one misses the most recent developments. Cases in point are the modern work on mam- malian and insect embryogenesis , the work on developmental compartments in insects, and the older and recent findings on the origin of primordial germ cells in urodeles. The author evidently had his aims firmly in mind all the time and he writes in an easy style which never becomes boring. Here and there the lan- guage tends to be imprecise, although there are very few major inaccuracies. The illustrations are mostly simple but very effective line drawings. A few of the captions lack in clarity. The literature lists are excellent, but some system of reference to them in the text is sorely missed. Why not use small superscript numerals? The book is reasonably well printed but has many printing errors and a weak binding. 4. M.SUSSiyiAN. 1978.

DM 29.00 (paper) This translation is based on the first edition (1973) of Sussraan's well- received text (see review in Gen. Embryol. Inf. Serv. 16, 1, 1975). The Ger- man title does not adequately reflect the book's nature, because it covers cellular aspects as well as the molecular ones. The translation reads very well but is by no means always entirely correct, It is doubtful whether the translator knew the field. Rather frequently, moreover, words or phrases from the original have mysteriously disappeared, altering the sense. The illustrations are faithfully reproduced, though without the original use of colour. The original brief reading lists are re- produced with printing errors and all. 5. B.P.TOKIN. 1977.

The resulting volume has much more than the ephemeral value of so many symposium reports. It is a series of interesting and competent reviews by Japanese authors, in which the foreign literature is covered equally well as the Japanese, and all of which are remarkably up to date. In addition, all authors write remarkably good English. Among the 14 contributions we specifically mention papers on growth and branching in Agrobacter'ium (Fujiwara and Fukui) , on the role of ribosomes in bacterial sporulation (Kobayashi and Domoto) , on cell differentiation in sporulating BaciZl'L (Kaneko) , on cytodifferentiation in the cell cycle of yeasts (Hayashibe) , on hyphal growth and morphogenesis in Fungi fNishi) , on photosporogenesis in Fungi imperfeoti (Oda and Kumagai) , and on fruiting body formation in Basidiomyoetes (Ishikawa and Uno) . The standard of production is very good indeed, and particularly the elec- tron micrographs are well reproduced. THEORETICAL AND MATHEMATICAL DEVELOPMENTAL BIOLOGY (see also 99,100,101) Monographs 8.

The organism as a cognitive and co-opera- tive system This book is a thought-provoking attempt to provide a picture of biologi- cal organisation valid from the lowest to the highest levels. The approach is based on molecular biology on the one hand and mathematical model building on the other: hence the word "analytical" in the title is to be understood in both the experimental and the mathematical sense. The author aims to show that there is no discontinuity of action in moving from problems of homeo- stasis and stability (chs.l and 2) to those of temporal organisation (chs.3 and 4), and finally to those of temporal and spatial order {chs.5 and 6). Higher-level systems (e.g. embryos) "continue to include in their operation all relevant activities of the lower-order ones" (such as self-regulating metabolic systems within cells) . In the last chapter this leads to what the author considers to be "a self-consistent and rigorous alternative to a re- ductionist position". The chapters of most immediate interest to developmental biologists are chs.5 and 6. In the first of these the discussion centres on morphogenesis in hydroids, cellular slime moulds and Acetobularia . The latter is included to emphasise that morphogenesis can occur without cell interaction. Therefore, the ensuing model for (morphallactic) linear morphogenesis starts from the cell membrane and is based on activity waves associated with it. The wave 191 model includes periodic "pacemakers" and provides "regulation" without ad- ditional assumptions. The discussion in ch.6 is likewise based on the notion of wave propagation. The chapter has sections on periodic patterns, on the insect epidermis, on the chick wing bud (with a wave model for epimorphosis) , on imaginal discs and the insect limb (with an interesting elaboration of the "clock-face" model of French et at.), and on retino-tectal projection in amphibians. The author concludes by saying that the notion of static diffusion gradients providing positional information will probably have to be replaced by a com- bination of wave propagation from defined organising centres, and (local or global) "clocks" of some kind which generate spatial and temporal periodici- ties. There is much more in the book (particularly in the last chapter) than can be done justice to here. The author aspires after a "balance between know- ledge and vision", and to grasp the significance of this the perusal of the entire book is necessary (even though for the average biologist the going is difficult in places) . 9. G.NICOLIS and I.PRIGOGINE. 1977. SELF-ORGANIZATION IN NONEQUILIBRIUM SYSTEMS; from dissipative structures to order through fluctuations Wiley, New York, etc. XIV, 491 pp., 124 figs., subject index. £ 20.75 Contents (abridged): I. The thermodynamic background (4 chs.); II. Mathe- matical aspects of self-organization: deterministic methods (4 chs.); III. Stochastic methods (4 chs.); IV. Control mechanisms in chemical and biol- ogical systems (4 chs.); V. Evolution and population dynamics (2 chs.) On reading the word self-organisation every embryologist pricks up his ears. Unfortunately this reviewer lacks all competence in mathematics, and all I can do here is to try and highlight the main features of this book and of its authors' thinking in order to bring them to the attention of develop- mental biologists. (In this notice I will often use or paraphrase the words of the authors without showing this by quotation marks.) Most of the striking results of classical thermodynamics refer to equili- brium situations. Later, linear nonequilibrium thermodynamics showed that nonequilibrium may be a source of macroscopic (global) order (the example adduced by the authors is thermal diffusion.) The results of the investiga- tions by Prigogine's group on situations further away from equilibrium, and involving nonlinear equations, can be sketched as follows. When a system (e.g. a chemically reacting mixture described by nonlinear functions of the variables involved) is forced further and further away from equilibrium, the equilibrium solution may become unstable and the system may evolve toward a new type of organisation (a new long-range molecular order) involving coher- ent space-time behaviour (cf . the Benard instability in liquids) . This type of organisation depends on appropriate feedback conditions; the new struc- tures that appear can be maintained only through a sufficient flow of energy and matter and are called "dissipative structures". (Turing's early work concerned one of the first dissipative structures ever studied.) The special interest of the biological applications of this approach dis- cussed in the book is brought out by the following quotation,: "While each of the important biomolecules discovered in the recent years is obviously formed according to the laws of physics and chemistry, we have to identify the mechanisms that make the "mass production" of these molecules possible and coordinate their production according to the needs of the organism. It has often been stated that biological organisation requires a series of structures and functions of growing complexity and hierarchial character. One of our main concerns is to understand the way in which transitions be- tween levels occur and to relate the molecular level to the supermolecular 192 one, and the cellular to the supracellular . The examples in Parts IV and V show that this problem can be formulated and in some cases solved using the methods we have introduced" The authors show that Boltzmann's order principle does not apply to dis- sipative structures, and that for these to appear it is necessary that small fluctuations are amplified and stabilised (cf. Turing). The role of fluctua- tions is studied in part III. This is probably the part of the theory where recent progress has been most spectacular. However, the approach combines both stochastic and deterministic elements in the time evolution of the macroscopic system; the deterministic elements suffice at points far from bifurcation and are treated in part II. The thermodynamic background is kept at a minimum and is treated in part I. Part IV has chapters on self-organisation in chemical reactions, on regu- latory processes at the subcellular level (with much emphasis on metabolic oscillations) , on regulatory processes at the cellular level (with a section on cell division) , and on cellular differentiation and pattern formation. One of the main goals of the latter chapter (which occupies 20 pages) is to analyse the origin of positional information, in other words, the onset of polarity in a morphogenetic field. The discussion is largely in terms of cell communication by means of diffusion of morphogens through the cytoplasm, although it is recognised that membrane-bound phenomena may also have to be invoked. Applications to morphogenesis in Hydra and Acetabularia are briefly discussed. Although what is said about morphogenesis in this book is clearly of a preliminary nature, my uneducated intuition tells me that the approach of the Brussels school may well profoundly affect our ways of thinking about pattern formation and, more generally, about the problems of biological organisation at the supramolecular level. 10.

The paper by S.Kauffman on dynamic models of the mitotic cycle has been published previously in Lecture Notes in Biomathematics, vol.13. It deals particularly with the author's "limit cycle model" developed for Physarum polycephalim. 193 The paper by H.Othmer, entitled Current problems in pattern formation, is almost entirely mathematical in content. It discusses patterns based on coupled "units" (cells) which are periodic or capable of being entrained by a periodic signal. It attempts to answer two questions: (1) under what con- ditions do the coupled units synchronise into a single collective mode, and (2) what properties of the internal (biochemical) dynamics and of the coup- ling produce non-uniform spatio-temporal patterns?

Concepts of the mechanism of ac- tion of the hormones It is a rare occurrence that a man who has been active in a field almost from its first inception is able to write a survey of it in ripe old age. This is what Professor Thimann has accomplished. The book is based on a series of lectures given for graduate students in 1974. It has been critical- ly reviewed elsewhere by botanists; this reader, a zoologist, particularly enjoyed the lively style of the narrative, conveying an impression of listen- ing to a highly gifted lecturer, and the frequent accounts of the historical origins of the subject. As will be apparent from the table of contents little will be found on the more strictly morphogenetic aspects of plant development. No attempt has been made at compiling a comprehensive bibliography, because this is available elsewhere, but the protagonists of the story are given due credit and geo- graphically located throughout the text. The chapter bibiographies are short and there is a brief list of supplementary reading at the end. The book is beautifully produced and illustrated. Monographs 13. R.BEIDERBECK. 1977.

DM 48.00 This book is a critical, up-to-date and extremely well-organised survey of the enormous amount of recent and older work on higher-plant tumours. It opens with a concise but excellent summary of the cellular principles of normal plant development (17 pp.) and a chapter on wound healing (8 pp.). In the last chapter tumour formation is again contrasted with normal histogene- sis, and a general frame of reference is given for cancer as a cellular phe- nomenon against the background of the genetic model of Ahuja and Anders (1976) . The main chapters of the book deal with crowngall tumours (95 pp.), virus- induced tumours and WTV (16 pp.), genetic tumours in Niootiana (19 pp.), 194 habituation of plant cells in vitro, tumours induced by chemicals and irra- diation, and White's fir tumour. Much attention is given to the nature of the causative agents, the mechanisms of tumour induction, and the effects on the host plant. The book is illustrated with line drawings and photographs. The bibliogra- phy contains well over 1,000 titles and is up to date until 1976. INVERTEBRATE DEVELOPMENT (general) Treatises 14. A.C.GIESE and J.S.PEARSE, eds. 1977.

The present volume has three chapters on gastropods {Prosobranahia^ Opisthobranahia and Fulmonata) and three on cephalopods [Nautiloidea^ Deoapoda and Octopoda) . The sections on embryonic and larval development are almost entirely descriptive in nature; that in the chapter on opisthobranchs is very short and the embryonic devel- opment of Nautilus is not known. The chapter on prosobranchs has been updated by a bibliography covering the years 1970- '76. The volume is a mine of information and is profusely and beautifully illustrated. Textbooks 15.

The pen- and-ink drawings are rather crude and the reasons given for not using photo- graphs are not convincing: in the few cases where a drawing is to be pre- ferred (whole embryos) much better ones could have been provided. Little care has been devoted to lay-out and production, particularly in the section on early development. Finally, the title is a linguistic horror. 196 DEVELOPMENT OF MAMMALS AND MAN (general) (see also 34,44,64,104) Textbooks 21. C.R.AUSTIN and R.V. SHORT, eds. 1978.

Park Press, Baltimore, etc. X,510 pp., numerous figs., subject index. $ 22.50, E 13.75 The reason why we review this book is that it is of interest to teachers of human anatomy and embryology. The starting point is that the human body is organised and that this organisation is most easily grasped and taught on the basis of embryonic structure. The book presents the gross anatomical details in "low key" but emphasises the basic simplicity of the body's com- position during embryonic and (early) fetal development. The text is short and the main emphasis is on the illustrations. These consist of numerous excellent line drawings which use red colour to empha- sise important structures and components and cover all stages of development up to the adult. The whole is didactically very clear and pleasing to the eye. Apart from a 50-page section on embryogeny the subject matter is treat- ed in four main parts: body wall, nervous system and related structures, cardiovascular system, and viscera. Appropriate literature is cited and listed in the 4-page bibliography. 23. J.LANGMAN. 1977.

It is based on the 3rd English edition (1975) and therefore now has half-tone illustrations as well as the famous line drawings. The translator has made some alterations in the original text with the permission of the author. Contrary to the 3rd English edition the chapter on experimental embryology has been retained and even extended by the translator. It is fairly modern in some areas but rather antiquated in the more strictly biological sections. It has no illustrations but is the only chapter in which the reference list has been retained. 197 /:4. K.L.MOORE. 1977. THE DEVELOPING HUMAN, clinically oriented embryology. 2nd edit.

The first edition was re- viewed in Gen. Embryol. Inf. Serv. 15, -2, 1974. The text was quite up to date at that time and has again been updated for this edition. Many illus- trations were modified or replaced by newer ones. The apparently successful format of the book is unchanged, but apart from the references each chapter now has suggestions for further reading for the beginning student. 25. G.H.SCHUMACHER. 1977.

In both cases it may perform a useful function, if only be- cause no one can deny that it is wholly original and entirely unorthodox. Regular readers of these book notices have been given glimpses of Blech- schmidt's way of thinking on previous occasions (see Gen. Embryol. Inf. Serv. vols. 12 (suppl.), 1968 and 16, 1, 1975) but this is the first time his ideas are laid down in a book first published outside Germany, thanks to the in- terest and help of the junior author, who is an American. The main premise of the book is that it is necessary to study human devel- opment right from the start by what is called "kinetic anatomy", viewing the embryo as a dynamically interacting whole on the basis of material movements and tissue forces deduced from painstaking morphological investigation. It is claimed that this leads to conclusions that invalidate evolutionary con- siderations and emphasise the uniqueness of human development. The resulting view is strongly epigenetic in character and accords only limited importance to the genetic information present in the chromosomes. This reviewer, not being an expert on human developmental anatomy, can only repeat what he said on previous occasions: let every reader judge the value of these views for himself. The book is produced with great care and is illustrated with micrographs, drawings and diagrams of outstanding quality. It is quite typical that the only literature cited consists of three books by the first and one by the second author (as well as some of Blechschmidt ' s publications in German cited in footnotes) . 28.

DM 148.00 This book will be mainly of significance to members of the medical pro- fession, but some chapters will be of interest to mammalian and human em- bryologists. All but one of the 17 contributors are Japanese researchers working either in Japan or elsewhere; they are all engaged in both basic and clinical research. The eight chapters are reviews intermingled with some- times considerable amounts of original material, some of which was not pub- lished previously. Two chapters are of particular interest to our readers. One is on the biology of mammalian embryos in pre-implantation stages (S.Suzuki et ai^., 16 pp.). The other is an extensive survey (Tanimura, 57 pp.) of findings on both normal and abnormal embryonic and early fetal human development based on the Nishimura Collection at Kyoto University (Human Embryo Center) . (This collection consists of material from legal abortions in Japan, and contains some 35,000 embryos, some 4,000 early fetuses, and over 2,000 sectioned specimens.) Other chapters deal with fetal growth and the intra-uterine en- vironment, the placenta, and the feto-maternal hormonal milieu. Two chapters are of exclusively clinical interest (sonar and amniocentesis) . All chapters have extensive reference lists. In the text it is not always made perfectly clear which data are original and which are not. The English is often clumsy and should have been edited. The book is well produced and profusely illustrated. The photographs are of very good quality and most of them are original. 29, M.I.SHERMAN, ed . 1977.

Teratocarcinoma cells and normal mouse embryogenesis As the editor says in his Introduction, "the purpose of this monograph is to provide the reader with a thorough overview of a few selected topics on manmialian embryogenesis that are of current interest and interrelate well with each other". The result is a resounding success. All chapters are lengthy, critical, well-written and well -organised reviews by both established and younger experts, most of them British or American. The chapters are well integrated by cross-referencing and all authors use the 199 same terminology, clarified in a brief glossary. All chapters deal mainly with early embryogenesis prior to and around implantation. One chapter bibliography has been updated until 1977, the others are up to date until 1976. The photographs and electron micrographs are well re- produced. 30. J. M. TANNER. 1978. FOETUS INTO MAN: PHYSICAL GROWTH FROM CONCEPTION TO MATURITY Open Books, London.

The volume deals with the basic and applied aspects of the freezing of embryos of the mouse and several other mammals. They are discussed by a group of specialists mainly from Britain and the U.S.A. One paper is of more immediate interest to embryologists : the largely theoretical contribution by Riggers et al . on transport mechanisms in the preimplantation mammalian embryo. The volume is produced with the meticulous care we have come to expect from this series. Reference works 32. INTERNATIONAL ANATOMICAL NOMENCLATURE COMMITTEE. 1977. NOMINA ANATOMICA. 4th edit.

Considerable revi- sions have been made, particularly as regards the nervous system (almost 200 new terms) . The book now contains for the first time the internationally ap- proved Nomina Histologiaa and Nomina Embryologica (34 and 36 pages, respec- tively) . The latter are now in Latin only, in contrast to the previously 200 circulated provisional list (1970). It is understood that each country is free to make its own vernacular translation. It is emphasised in the introduction that all anatomists, histologists and embryologists can send criticisms and suggestions of all kinds to the Inter- national Anatomical Nomenclature Committee at all times, and that this is important for improvement of the fifth edition (to be submitted to the Mexico World Congress in 1980) .

The book has therefore been entirely recast and is now in three volumes. Only the first is examined here. It deals entirely with vertebrates except for the last chapter (on the ovary and secondary sexual characters) , which has a brief section on inverte- brates. The chapters are well-organised, authoritative reviews. The chapters of most immediate interest to our readers are those by Zuckerman and Baker on ovarian development and oogenesis (sensu striata) , by Haffen on sexual differentiation of the ovary, and by Wolff and Haffen on natural and experimental modification of ovarian development. The chapters on the structure of the mammalian and non -mammalian ovary, by Harrison and Weir, and Dodd, respectively, of course also contain much that is of inter- est. Not all chapters are equally up to date: some go until 1975 but others no further than 1972/73. The book is illustrated with very good light and elec- tron micrographs and line drawings. (Vol.11 will contain chapters on the control of ovarian development in in- vertebrates, on the development of estrogen-sensitive tissues of the genital tract and mammary gland, and on ovary transplantation.)

Repro- duction and society Although this book was written primarily for advanced students it will be very useful as an introduction for those starting work in mammalian embryol- ogy. The subject matter is restricted to mammals but within these limits the book is comprehensive and up to date. The author has achieved a good compromise between relying too heavily on the laboratory rat and placing too much emphasis on the diversity of repro- ductive strategies among the mammals. The amount of embryology in the strict sense is understandably limited. Although no references are cited in the 201 text, there are good lists of further reading leading on to more specialised publications . The book is well produced and illustrated. Monographs 35. E.

DM 240.00 This superb atlas is in the form of more than 30 brief chapters by an in- ternational band of 55 authors, grouped into three main sections: Male re- production. Female reproductive organs, and Eggs and pregnancy. Many chap- ters have the format of a brief publication and several report previously unpublished data. The third section has four chapters on the cumulus oopho- rus and fertilisation, four on cleavage and blastocyst development, and one each on other subjects such as the placenta and the amniotic membrane. Nor- mal and pathological processes receive equal consideration. The species studied varies with the subject. Most of the more than 350 illustrations are of course SEM pictures, usual- ly two to six on a page, of very good quality and at a wide range of magni- fications. These are supplemented occasionally with good drawings in the text and some TEM pictures and photomicrographs. The book is well produced on high-quality glossy paper. 36. W.KUNZ and U.SCHAFER. 1978.

M 25.00 (paper) This monograph in fact consists of two lengthy and well-organised reviews, one of 52 pages on oogenesis by the first, and one of 25 pages on spermato- genesis by the second author. The first part is largely restricted to the growth phase of the oocyte, and in both parts the emphasis is very much on molecular aspects, to the virtual exclusion of ultrastructural morphology. The subject matter is largely restricted to findings in amphibians and sea urchins in part one, and in Drosophila and mammals in part two. Part one has sections on the role of maternal hRNA and rRNA in the embryo, and on the am- phibian oocyte as a system for studying nuclear and cellular differentiation. Each of the two parts has its own selective bibliography; both run into early 1976. The volume has good diagrams and a number of electron micrographs showing lampbrush chromosomes, extra-chromosomal DNA and multiple nucleoli. D-issertations 37. B.GRIFFOND. 1977.

A major feature is the emphasis on monotreraes and marsupials. The 47 papers were reproduced directly from typescripts and vary tremen- dously in format. No discussions are recorded. Of the five sections into which the papers are arranged, that on Embryo- maternal interactions and the evolution of viviparity is of most interest to our readers. It contains 13 papers describing work on lizards, mono- treraes, marsupials and eutherian mammals. Nine of the (first) authors are Australian. The summing-up of this section by McLaren is well worth reading. Other sections deal with Evolution of sex determination. Comparative as- pects of reproduction in male vertebrates, and Ovarian cycles and luteal function. 39. H.LUTZ, P.LUBET and H.CHARNIAUX-COTTON, organisers. 1976. DIFFERENCIATION SEXUELLE Soc.

F.Fr.65.00 (paper) This symposium took place in Paris in July 1977 and had a widely interna- tional attendance. Almost all of the 37 contributions are brief reports of recent research; all are in English with French summaries. They deal with mammals, some lower vertebrates, and some invertebrates (particularly star- fish) . Two of the four sections contain papers of interest to developmental biologists (we give the names of the authors concerned in parentheses) . Section 1 is entitled Interaction between somatic and germ cells in the em- bryo (Burgoyne, Byskov, Carlon and Erickson, Wai-Sum O arid Baker) . Section 3 is on Cell interaction in the ovary (particularly oocyte maturation: Guerrier et at., Jalabert, Moor, Ozon et at., Schuetz and Cloud, Szollosi et al., Zeilmaker) . The other sections deal with Genetic control of meiosis and Testis cell relationships. The volume is well printed and illustrated with top-quality photographs. 41.

It is based on a symposium held in Oxford, Ohio in August 1976 and contains a series of reviews of recently completed 203 research by recognized authorities from eight countries. We single out the following contributions as being of special interest to our readers: Studies of the life histories and reproduction in North American plethodontid salamanders (Tilley) ; Life history patterns and reproductive biology of neotropical salamanders (Houck) ; Aspects of the reproductive biol- ogy of Japanese anurans (Kawamura and Nishioka) ; Systematics and hybridiza- tion in the Rana esaulenta complex (Berger) ; and Cytotaxonomy and cytogene- tics in European newt species (Mancino et at.).

Methods and concepts of biometrics applied to tera- tology One or more volumes of this monumental multi-author treatise have already been reviewed and, on the whole, acclaimed in the scientific press (see e.g. Nature 27d) . We list the tables of contents as a service to our readers. The work is a veritable mine of information and will be invaluable to all teratologists and particularly to beginning investigators. Reviews such as the chapters 2, 4, and 7-10 in vol.2 are also of interest to mammalian em- bryologists generally (the authors are Gluecksohn-Waelsch, W.J.Scott, Jr., Grabowski, Saxen, K.M.Yamada, and Kochhar and Larsson) . The same holds for chs.4 and 5 in vol.3 (by Nishimura and Shiota, and Beck and Lloyd). The volumes are well produced and illustrated. 205 Monographs 45. H.BANKL. 1977.

It is very practical in outlook and embryologists will find little in it that will interest them specifically. The first three chapters (53 pages) deal practically and sensibly with the principles of drug testing and the evaluation of teratogenic (and other) effects, as well as the relevance of animal studies for man. The rest of the book is devoted to discussions of more than 1,200 drugs classified into 27 groups according to pharmacological activity. They are restricted to chemi- cals which are in use or intended for use as therapeutic agents. Mouse, rat and rabbit are emphasised as test animals but other species are also con- sidered, as well as, of course, the human. The data are drawn together in informative tables wherever possible. The use of illustrations is incidental and the photographs are not very well reproduced. All chapters have extensive bibliographies which are up to date until 1975. 206 Books of readings 48.

Most papers date from about 1950 till 1975; four older papers are historical classics by Murphy, Hale, Gregg, and Barr and Bertram. The papers are grouped in eight sections, of which we mention four: Teratological mechanisms (papers by Roberts and Powell, Saxen, Wilson, and Dunn); Cytogenetic and chromosomal studies (10 papers); Environmental influences and congenital abnormalities (24 papers) ; and Detection of environmental teratogens (papers by Persaud and Doll) . A few papers have been translated or abridged. The editor's commentaries have their own references and the book is con- cluded by a list of further references containing some 140 titles going into 1976.

The symposium was held in Aspen, Colo, in August 1976. All contributors but one were Americans. The 18 brief contribu- tions are best characterised as progress reports and the volume is thus an interesting but probably short-lived "instant photograph" of the state of this important field. If we mention a number of contributions specifically, this does not mean that the others are not of interest to developmental biologists. Moscona writes on embryonic cell recognition, O'Malley on hormone receptors and gene transcription, Kuo and Garen on maternal contributions to embryogenesis in Drosophila. The differentiation of cartilage is discussed by Dorfman, cell differentiation in normal hematopoietic and leukemic ceils by Sachs (Rehovot) Pierce and Mintz deal respectively with teratocarcinoma and genetic mosaics in the mouse. The volume also contains reports of five workshops on modern techniques, among them complementary DNA, cell fusion, and immunohistology. These have their own reference lists.

In this admirable monograph the most outstanding expert in this field provides a clear review, without duplicating previous reviews, by concentrating on the most recent advances. Many of these are unpublished observations by himself, his one-time and present associates, and other col- leagues. This is done against a solid and often thought-provoking theoretical background. Some of the main topics, aside from the necessary background material, are cytoplasmic shedding and cell surface alterations during dedif ferentiation, the role of the cell cycle, and the role of cyclic nucleotides in the control of cell configuration (studied by micro-injection of cultured cells) . There are also brief general chapters on the parallels between lens and limb regen- eration in amphibians and on the problems of cell rejuvenescence and the re- programming of differentiation pathways. The book is very well illustrated; most of the photomicrographs are origi- nal. The bibliography is up to date until 1976. B-issertations 54. B.LASSALLE. 1978.

XXII, 646 pp., 220 figs., 16 tabs., author and subject indexes. $ 49.50, SFr.160.00 This collaborative treatise by 23 North-American, five English and two Swiss authors is a mine of information. The 17 chapters are authoritative and well organised reviews which cover an extremely wide range of subjects in- cluding structural, biochemical, pharmacological and physiological aspects. The periods covered are embryonic and fetal life, the perinatal period, and childhood. The authors have been encouraged to speculate wherever appropriate in order to stimulate discussion. There is some overlap among chapters but this is in- tentional. Relatively little attention is devoted to the beginnings of organ- ogenesis and particularly its causal aspects. The chapters are arranged more or less arbitrarily in four sections as fol- lows: I. Structural development (6 chs.), II. Biochemical development (5), III. Physiological development (5), and IV. Abnormalities of the developing lung ( 1 ) . The book is produced in good offset print and is well illustrated; the light and electron micrographs are of very good quality. Monographs 58.

The book reflects the fact that this field of neurobiol- ogy is a very new one; the various contributions are rather disconnected and many contributors stress the tentative nature of their reflections. The 13 chapters are well-organised and up-to-date, in-depth reviews, some broad in scope but others largely restricted to the authors' own recent experimental research. They deal with a large variety of systems: para- and sympathetic ganglia, spinal cord, various brain regions, regenerating axons, most of them studied in mammals but some in lower vertebrates. The tech- niques employed vary from anatomy to biochemistry. A central theme in many contributions is "synaptic remodelling", also called "reactive synaptogene- sis" . The book is beautifully produced and illustrated with a profusion of ex- cellent line drawings and light and electron micrographs. 59. F.HAD^ISELIMOVIC. 1977.

Neuronal specificity and development of neu- ronal circuits The first edition of this book (1970) has received wide acclaim. The author has now undertaken the task of thoroughly revising the book, a task both arduous and necessary because of the rapid growth of the field inside a decade. This is reflected by an increase in length of about 80% (both more and larger pages) and a rise in the number of illustrations from 93 to 137. The book has been virtually rewritten and the contents rearranged, as reflected in the table of contents above. Each new major topic is pre- faced by a section highlighting the main problems and theories, often in a historical context. The book is well produced. The bibliography (which is not exhaustive) contains over 3,000 titles, as against some 2,200 in the first edition; it is up to date until 1976, with occasional references of 1977/78. An author index is sorely missed; the bibliography could easily have been used for this purpose. 63. G.S.KVINIKHIDZE. 1975.

The viewpoint is structural and little attention is devoted to teratogenetic mechanisms, except in a brief chapter in the last section. The table of contents above speaks for itself. From section II onwards, each chapter begins with an analysis of normal development of the part of the nervous system in question. The parts are arranged according to the con- cepts of Meyer and Hausman rather than serially from anterior to posterior. A special feature of the book are its very clear and useful graphic illus- trations, which summarise many data on the basis of log/log plots of, for instance, body length against gestational age. The numerous photographic il- lustrations are of good quality. Each chapter has a separate reference list. 65. R.ROHKAMM. 1977.

E 28.50, $ 55.75 The papers of this volume, though based on a symposium held in Cambridge, England in 1974, have been edited and updated until 1977. From among the 32 contributions we single out those that appear to be of interest to our readers. The problems of epithelio-mesenchymal interactions and histogenesis in tooth development are addressed in one way or other by Kollar (role of col- lagen) , Osborn (sequence and timing of tooth initiation) , Miller (dentition in mouse mutants) , Moss-Salenti jn (vestigial teeth in mammals) and Shellis (tooth formation in fish) . Osborn provides an in-depth discussion of field versus clone theories as relating to the regional organisation of the den- tition. Lombardi contributes a factor analysis of "morphogenetic fields" 212 in human dentition, while Sof aer ' s study of developmental stability in the mouse vertebral column provides interesting material for comparison with tooth rows. Luke et at. discuss the problem of ageing human fetuses on the basis of their tooth germs. The book is well produced and profusely illustrated. 71. D.A.EDE, J.R.HINCHLIFFE and M.

Of the 29 papers, one is a review and several are reports of unpublished work. The others are concise but well-written mixtures of recent published work and new findings, in varying proportions. Particularly in the area of avian limb morphogenesis there is much overlap and little or no "interaction" between the papers: each contributor brings his own slightly different point of view, and it is therefore a pity that the discussions were not recorded: they must have been fascinating and enlighten- ing. Nevertheless, there is in the papers a wealth of material that was very new at the time of writing; much of this represents important advances which show that several ideas which were s© far generally accepted are no longer true. Sixteen papers deal with limb morphogenesis in birds, five with mammalian and reptilian limbs, three with amphibian limb regeneration, and five with somitogenesis in amniotes and amphibians. The book is illustrated with good drawings and photographs. 72. O.C.JAFFEE, ed. 1970.

The papers are mixtures of review and research material in vari- ous proportions, and all but a few are followed by group discussions. They deal almost exclusively with the epidermis in the strict sense, excluding melanocytes and special epidermal differentiations (except hairs in 2 papers) but including wound healing (3 papers) and chalones (1 paper). Most 213 of the material relates to mammals and man (frequently abnormal differentia- tion) , but a few papers bring in material of other vertebrate orders. The 32 papers are arranged in four sections as follows: Morphological as- pects of differentiation (7 papers) , Control mechanisms of skin metabolism (8) , Control mechanisms of epidermal differentiation (9) , and Biochemical characterization of epidermal cell constituents (8) . The volume is well produced and illustrated, among other things, with many good light and electron micrographs. Colteations of papers 74. N.E.ALANIYA et at. 1977.

Regeneration and totipotency of cells and nuclei The title of this book is a little misleading in that the area covered is much broader than nuclear structure: in fact it deals with the nuclear and sub-nuclear phenomena associated with developmental processes of widely vary- ing kinds. The book's great value lies in the fact that examples are taken from both the plant and animal kingdom, so that it repeatedly provides new insights for the specialist working with material from either kingdom. The aim of the book is not clearly stated and it has no distinct "connect- ing thread". Moreover, the treatment is a little idiosyncratic in places and some important subjects are treated cursorily or not at all. A case in point is the relation between proliferation and differentiation, and more particu- larly the theory of "quantal mitoses". 214 The book is illustrated with good line drawings but there are no photo- graphs. The bibliography covers 48 closely printed pages and is up to date until 1975. 77. D.R.GARROD, ed. 1978. SPECIFICITY OF EMBRYOLOGICAL INTERACTIONS Chapman and Hall, London. Receptors and Recognition Series B, vol.4. XII, 274 pp., 64 figs., subject index. £ 15.00 Contributors: Barondes, Curtis, Gaze, Hermolin, Lilien, Lipke, Noden, Rosen, Steinberg, Turner This book is not about interactions among embryologists , as suggested by the title, but about specific cell adhesion and the resultant cell position- ing in development. It is a collection of authoritative, critical and well- organised reviews on a broad, though not exhaustive range of aspects of the problem. The discussions are both descriptive and analytical and up to date till the last moment. Most authors draw heavily on their own research but place it in a broader perspective. Some chapters have a pronounced theoretical slant, notably those by Gaze (nerve connections) , Steinberg (cell ligands and differential adhesion) and Curtis (the "morphogen" theory of cell positioning) . These chapters will be required reading for all those working themselves in these fields. The first two chapters deal with specific cell positioning in vivo - of neural crest cells and in the nervous system, respectively. Chs.3-5 discuss the adhesion and sorting of cultured cells, while the last two chapters con- centrate on two model systems, the sponges and the cellular slime moulds. The volume is well produced and illustrated. (A final remark on the title: there are many more kinds of cell interactions than those discussed here; and why do so many writers these days use "embryological" instead of the perfectly unambiguous adjective "embryonic"?) 78.

Immunological functions of lymphoid tissue in vitro ; V. Cell lines in lymphoid and he- matopoietic tissue This book was published in Russian in 1972 but was revised for this trans- lation. The main part of the book presents the results of organ and mono- layer culture of lymphoid and hematopoietic tissue (including stromal mecha- nocytes) obtained by the author and her collaborators (notably A.Ya.Fri- denshtein) at the Gamaleya Institute in Moscow. These are placed in histori- cal perspective and discussed mainly against the background of other work in the USSR. An appendix specially written for this edition by Luriya and Fridenshtein provides valuable technical and methodological information on work carried out recently at the above institute, particularly the cloning of fibroblasts in monolayer culture and the culturing of various organs. The book is well produced and illustrated with good line drawings and pho- tographs. The bibliography contains some 350 titles, about 30 of which (by both Russian and non-Russian authors) are more recent than 1972; there is no way of telling which papers are in Russian. 215 /y.

Further mechanisms of nuclear DNA variation, 5, Control of en- ■ dopolyploidization and polytenization, 6. Functional significance of endo- cycles, 7. Evolutionary aspects The main value of this book for our readers lies in the fact that it brings together a mass of data from both animals and plants showing that endopoly- ploidy is a much less exceptional phenomenon than many biologists think. I quote from Chapter One: "It is one of the chief intentions of the present work to demonstrate that the nucleus and its DNA and chromatin exhibit a dynamic organization rather than a constant one. The collection of data on endopolyploidy and differential DNA replication may show that most cells of most organisms do have quantitatively and qualitatively different DNAs in their nuclei. The extensive review of the data offers the chance to under- stand developmental variation of DNA and chromatin as an important factor in gene regulation and cell differentiation". The author feels that this DNA variation is involved both in the characteristic form and function of a species and in its realisation during development. The table of contents above speaks for itself. In ch.6 most of the exper- imental evidence cited derives from insect and particularly plant studies (many of them by the author and his associates). At the end of ch.7 the author presents a "DNA optimisation model" to account for some relationships between nuclear DNA variation during ontogenesis, anagenesis and cladogenesis . He ends by expressing support for a recent statement by Britten and David- son's group to the effect that "divergence during phylogenesis and ontogene- sis are two sides of the same coin, or, in other words, speciation and dif- ferentiation are two sides of DNA variation". The book is concluded by a glossary and a guide to the literature pertain- ing to methods (molecular-biological and otherwise) . The bibliography runs into 1977 and covers 50 pages of small print. The book is beautifully pro- duced and superbly illustrated. A.NESSI de AVINON. 1977.

The specialists will by now have read the definitive publications anyhow, but the book seems well suited to recommend to postgraduate students as collateral reading. The symposium was held in Helsinki, Finland in August 1976 and brought together a representa- tive group of workers in areas that are in the forefront of the developmental and cell biology of today. The 24 main papers are arranged in five sections as follows: Early deter- minative events in embryogenesis (4 papers) ; Positional information and morphogenetic signals (4) ; Morphogenetic tissue interactions (7) ; Molecular mechanisms of cell contact interactions (5) ; and Cell recognition (4) . Each section is opened by a concise chairman's introduction clearly setting out the main problems (these are by McLaren, Wolpert, Saxen, Weiss and Moscona) . The volume is adequately produced and illuscrated. (Personal remark by the reviewer: in view of the discoveries by Nieuwkoop and co-workers and others on mesoderm induction in the amphibian blastula, I feel it is about time to drop the term "primary induction" and only to use "neural induction".) 83.

Neural differentiation (Frank, Macagno) The title of this book should have contained the word "development". It is based on a symposium held in Woods Hole, Mass. in September 1976 and is one of those few symposium volumes that are sure to leave a lasting mark. All contributions are short to medium-length reviews of very recent work in a limited area, but they were all obviously prepared with great care and are well integrated by cross-referencing. A great variety of mostly verte- brate cells and tissues pass in review, on which the most modern methods are brought to bear . The book is produced with exemplary care and illustrated, among other things, with a host of beautiful half-tones. 85. R.A.LERNER and D.BERGSMA, eds. 1978.

Cell-surface membrane complex (3 papers); II. Or- ganelles and supraraolecular assemblies (4); III. Cell surface proteins (8) ; IV. Cell-cell interactions (9); V. Communicating cell systems (10); VI. Cell patterning (2) More than one third of the 36 papers in this conference report are of direct interest to developmental biologists. This reflects the fact that cell interactions (why is the ugly phrase "cell-cell interaction" increasingly used?) are often best studied in developing systems. The conference took place some time during 1977 in La Jolla, CA and the large majority of contributors are Americans. The papers vary widely in scope; most can be characterised as progress reports. Many developmental biologists will also be interested in the "non-developmental" papers, partic- ularly those dealing with lymphocytes and histocompatibility antigens: the latter are increasingly suspected to have much more profound functions than those expressed in graft rejection alone. The papers of primary interest to our readers are in sections IV-VI. The last section is made up by two brief reviews by Bryant (epimorphic fields) and Wolpert (chick limb development) . Section V has no less than six papers on cellular slime moulds, some of them unconnected with the theme of the con- ference (genetics and gene expression) . Section IV has a long paper by Boyse and Cantor on immunogenetical aspects of biological communication, which contains most interesting speculations. Other papers are on the T-locus of the mouse, on "cell-adhesion molecules" in chick embryos, and on fertilisa- tion in mammals and sea urchins. The volume is well produced and illustrated. 86. B.I.

This sympo- sium, which was held in Manchester in April 1977, was unusual in that many developing systems were considered from the viewpoint of stem cells (or rather "cell lineage") which are not usually so considered, e.g. developing and regenerating limbs (Wolpert), the mammalian embryo (Papaioannou et at.), 218 insect development (Nothiger et al.), plant growth and development (Barlow), and lens development (Clayton) . Most of the papers in this volume are high-quality, up-to-date reviews of recent research by predominantly Anglo-Saxon authors. The first contribution (Holtzer) is particularly important theoretically in that it discusses the occurrence of multipotent versus bipotent stem cells in animals, coming out strongly against the former. The nine authors not mentioned above deal with such subjects as lymphocytes (1 paper), haemopoiesis (6), the epithelium (1) and the intestine (1). It seems a pity that the discussions could not be included in the book be- cause the interdisciplinary exchanges must have been fascinating to hear. The book is well produced and illustrated. 87.

Because the symposium was held as far back as 1975 we only briefly mention it for those who may have missed it. It suffices to say that the second half contains six papers on various cellular and metabolic aspects of myogenesis in vitro by recognised author- ities in the field: Holtzer, Konigsberg, Nameroff, Hauschka, Stockdale and Strohman. 88.

Control of differentiation and neoplasia: i Molecular mechanisms of gene expression (8) , ii Gene expression in early development and cancer (4) , iii Stability of differentiation (5) The rationale for this symposium is neatly expressed by Markert in his keynote address: In summary, the difficulty with defining and understanding neoplastic change is the same difficulty that developmental geneticists have in under- standing normal cell differentiation. When we understand one, we shall surely understand the other. No one can predict whether progress will be more rapid with a focus on normal cells or on abnormal cells. I believe it is all the same problem - perhaps the most important practical and theoret- ical problem facing us today in the immense area of cell biology. 219 The symposium took place in 1977 in Houston, Tex. Of the 28 papers in the sessions listed above six are by groups or individuals outside North America. Most are short to medium-length reviews of recent research, sometimes against a background of older work. Viewed as a whole the volume is a (temporary) milesrone on the way to further knowledge in a field expanding at a stupen- dous rate. Throughout the book the emphasis is on gene expression in mammalian cells. The cell surface and the cytoskeleton figure in only a few papers. In section II. ii two papers deal with amphibian material. Preceding the symposium proper there is a 27-page "award address" by Mintz entitled Genetic mosaicism and in vivo analyses of neoplasia and differentiation. The symposium is con- cluded by a summary by J.Paul. The volume is very well produced and profusely illustrated; the quality of the many half -tones is excellent.

Although the design of the series has changed slightly, this volume fulfills the expectations engendered by the first volume. The chap- ters are authoritative and well-organised reviews ranging in length from about 30 to about 80 pages, and describe the scene as it was by the end of 1976. The numbers of references per chapter range from about 100 to about 300. The first chapter reviews genetic recombinant techniques and serves at the same time as background material for several other chapters, notably ens. 4 and 9. The practice of including editor's comments has been abandoned in this volume, so that it now almost exclusively addresses the specialist. The book is well produced and adequately illustrated.

In revising and extending it the author has ventured even further into the domain of cell biology than he did before. 220 The first chapter containing much new material is that on DNA replication (ch.9). From ch.l4 onwards this becomes the rule. There are two new chapters: The essence of being eucaryotic (42 pp.) and The control of cell prolifera- tion (44 pp., but incorporating material from original earlier chapters). The chapter on cancer has been completely reshuffled and greatly extended. The advances in molecular embryology (ch,17) are well covered. Only the very latest developments such as teratocarcinoma work and the H-Y antigens are missing. The lay-out of the book has been modernised, there are 185 more figures than in the previous edition, and all the figures have been re-styled. Monographs 92. W.BEERMANN, ed. 1977.

DM 78.00, $ 34.40 The four contributions in this book are exhaustive reviews of recent bio- chemical work centered on different, well-characterised insect gland sys- tems: the silk gland of Bombyx (Suzuki, 45 pp.); the follicular epithelium and its products (particularly the egg shell) in various insects (Kafatos and many other authors, over 100 pp.); the salivary gland of Cht-ronomus (Grossbach, 50 pp.); and the salivary gland of Aor-iootopus (Baudisch, 16 pp.) All chapters are well organised but their format and scope is quite dif- ferent. The second is almost a monograph in itself and sketches in a lot of background of a general nature. It also has sections on the comparative morphology and chemistry of insect chorions, on the chemical morphogenesis of the silkmoth chorion, and on chorion mutants in Bombyx. Apart from silk- moths Dvosoph-ila is considered in a separate section of some ten pages. The first three chapters are up to date until 197 5/76, the last until 1974. The book is very well illustrated. Dissertations 93. W.MINUTH. 1977.

Of the 36 contributors 14 came from East and West Germany and the others from ten other countries. Many are established authorities in their res- pective fields. The papers vary greatly in format and were only minimally edited. The large majority are surveys of recent research. The discussions are not recorded. The table of contents shows the very broad scope of the symposium. The or- ganisms on which research was reported range from viruses and bacteria through lower to highly organised eukaryotes. The volume is produced in offset print and is illustrated with line drawings and photographs. 96. J.PAPACONSTANTINOU, ed. 1976.

The contributors were encouraged to emphasise the latest find- ings of their own laboratories. The first section of the symposium is not covered by the symposium title. It has papers on organisation of proteins in chromatin, on the role of non- histone proteins and nuclear RNA polymerases, and on the formation and translation of mRNA in mammalian and slime mould cells. The second section deals with the action of steroid hormones in the chick oviduct, the rat pi- tuitary and uterus, and Xenopus liver. In these papers of course steroid receptor molecules loom large. The last section consists of a paper on hor- mone action in the barley aleurone system. The book is well produced and illustrated. 97. J.G.SCANDALIOS and G.S.WHITT, eds. 1977.

Epilogue This erudite and scholarly work has already been extensively and critical- ly reviewed in the scientific press (see Science 199, Nature 272, Amer. Scientist 66). We will therefore only briefly characterise it here. The first part of the book is historical and makes delightful reading not only for biologists but for any cultured person. (Ch.5 has brief excursions into criminal anthropology, racism, child development, primary education and psychoanalysis.) The second part is intended as "a reasonably complete analysis of current theory", but it is also full of original, thought-provoking ideas. It begins by discussing four questions: How shall we depict phylogeny?; How can onto- geny be related to phylogeny?; How are parallels between ontogeny and phylo- geny produced?; Which is more important in producing these parallels, the shifting of stages by acceleration and retardation, or by prolongation and truncation? It appears in the chapters that follow that the author places much emphasis on paedomorphosis and the two distinct processes that give rise to it: progenesis and neoteny. Both can yield "rapid and profound evo- lutionary change in a Darwinian fashion without the spectre of macromuta- tion". Inasmuch as paedomorphosis is an instance of heterochrony, and hete- rochrony is tantamount to developmental regulation, the author believes that "an understanding of regulation must lie at the centre of any rapprochement between molecular and evolutionary biology [via] the common field of development" . Two features of Part Two worth highlighting are a critique of G.R.de Beer's 223 influential books and a defense of L.Bolk's views on fetalisation. The book is very well produced, has extremely interesting illustrations, and is concluded by an excellent glossary, 100. M.de ISSEKUTZ WOLSKY and A.WOLSKY. 1976.

SFr./DM 44.00, ca. $ 17.00 (paper) Contents (abridged): I. Genes and mutations: the metamorphosis of 20th century ideas, II. Natural selection: a 19th century proposition. III. Behavior and evolution: a new road on old foundations This erudite book will be read with profit by all those interested in theories of evolution. The reason why we briefly review it here is that the authors are well-versed in developmental biology and that consequently their way of thinking is rather akin to that of people like C.H.Waddington. In other words, they constantly emphasise the necessity of thinking of orga- nisms not as finished products but as highly integrated developing entities. The book is essentially a theoretical critique of neo-Darwinism (or the "synthetic theory" of evolution) . It surveys and comments upon the trends of thought which have emerged alongside the "synthetic theory", and which point the way to a more widely based synthesis (while of course staying away from classical Lamarckism) . Part I and II will be of most interest to our readers. In part I the au- thors, after surveying modern ideas of molecular genetics, revive Gold- schmidt's ideas on "systematic mutations" in the context of more recent evi- dence. They also devote considerable space to Dalcq's concept of "ontomuta- tions", but are careful to point out that there is no evidence for them as yet. An important theme in part II is the limited role of natural selection and the ensuing conviction that evolution is essentially an autogenic (as against ectogenic) process. Interesting (though entirely theoretical) ideas are de- veloped concerning the strategic role of the genes controlling the basic features of embryogenesis : these culminate in the somewhat provocative statement "ontogeny is the cause of phylogeny". Part III emphasises the integrative role of the nervous system and its im- plications for the progressive emancipation of higher animals from their en- vironment. Dissertations 101. L. A.

It should be required reading particular- ly for graduate students entering the field. All papers contain a judicious blend of review material, recent results, and occasional pointers to the fu- ture. The symposium was held in June 1976. Those who know the field will re- alize from the list of contributors above that virtually all frontier areas are represented. Almost all contributions are well illustrated.

The basic organisation has remained the same but the book has been updated and the contents somewhat rearranged. There are new chapters on the placenta, post- natal growth, the skeleton, blood coagulation factors, nutrition of the newborn, trace elements, and the auditory response. The book is now produced in one volume, and less luxuriously, so that the price could be kept at a reasonable level. 225 Monographs 105. S.SAKAMOTO et ol . 1911.

Besonderheiten der iramunologischen Regulation der Embryogenese bei Saugetieren und beim Menschen (Werbitzky) This is the translation of a book published in Russian in 1973. The name of the first editor, who wrote a book on immunoembryology in 1962, is usual- ly transliterated in the West as O.E.Vyasov. He is one of the outstanding authorities in this field in the U.S.S.R. Obviously the main importance of the book is that it provides an entry into the older Russian literature. The bibliography contains some 350 titles, about one third of which are Russian; many of these are books and dissertations. We make the following annotations with the table of contents. Ch.l has sections on the phylogenetic and ontogenetic development of immunological reactivity and on the ontogenesis of specific cellular reactions. Ch.2 has a section on tissue antigens of the retina. Ch.3 deals with frogs, chickens, mammals and man. Ch.5 contains much information of clinical importance. The book is mainly illustrated with photographs. The bibliography is dis- figured by numerous printing and transliteration errors. Symposium reports 107. R.E.BILLINGHAM and A. E.

This symposium was held in New York in August 1976. Apart from a 5-page introduction by the chairmen, the 18 contributions are brief reviews or research reports, the latter usually either preliminary communications or extensions of previously published work. At least half of the papers are of interest to mammalian immuno-embryologists. Most of their authors are Ameri- can, some English. Some other papers may be of marginal interest to our readers.

Because this is rapidly becoming a very specialised field the book will appeal most to specialists. Of the 57 contributing authors all but four were Americans. The discussions following the papers are also recorded. Most of the 23 papers contain new information, often unpublished at the time of writing. They cover the fetal, perinatal and neonatal development of man and other mammals. Some highlights are new data on the ontogeny of T and B cells and their interactions, on the complement and properdin systems, on phagocytosis and the role of macrophages, and on the function of alpha fetoprotein in immunoregulation. 109.

The present international symposium bears witness to this. It was held in Aberdeen in September 1977 with an attendance of over a hundred scientists from all over the world. A special feature of the sympo- sium was the large number of papers dealing with invertebrates (in the "phylogenetic" section) and lower vertebrates (particularly fish, Xenopus and some reptiles) . All of the 56 contributions are brief research reports or reviews of recent findings. They are reproduced from typescripts without editing. A very useful feature, commendable for other symposia, is the very readable 13-page summary of contents prepared by the editors. Two of the three sections are of particular interest to our readers: that on Lymphocyte differentiation (highlighting the emergence and differentia- tion of lymphocyte sub-populations, and cell surface immunoglobulins and antigens)^ and that on Development of antigen-driven immune function (high- lighting T and B cell interrelations in fishes and amphibians, thymectomy in amphibians, immunoglobulin phylogeny, ontogeny of T suppressors and lyraphokines, bursa and immunological responses in the chick, and sequential maturation of the immune response) . The book was produced very well and extremely rapidly but has no indexes. 227 METHODS (see also 50,78) Symposium reports 111. D.NEUBERT, H.-J.MERKER and T.E.KWASIGROCH, eds. 1977.

Planning of experiments and choice of animal species (8 pa- pers) , II. Evaluation of teratogenic effects on organ systems and the skeleton (8) , III. Evaluation of postnatal manifestation of prenatally in- duced lesions (4) , IV. The use of in vitro techniques in teratology (7) , V. Special methods of drug application (2), VI. Methods used to detect alterations in genetic material (2), VII. The use of special morphological techniques in teratology (8), VIII. The use of special biochemical and toxicological techniques in teratology (8) This book is the result of the first European Teratology Workshop, held in April 1977 in West Berlin. Its aims were, first, to provide newcomers to the field with an opportunity to gain an overview of the research methods current- ly in wide use; and second, to give the scientist with more experience in these fields the means by which he might broaden his horizons by learning additional scientific methods. The volume collects all the methods and tech- niques, both established and new ones, demonstrated at the workshop in a series of 47 brief papers with charts, diagrams and other illustrative mate- rial. Twenty- two of the 37 first authors are from West Germany, many among them from the Institut fur Toxikologie und Embryonal-Pharmakologie , Free Universi- ty, Berlin, where the workshop was held. The other authors are from various other European countries. Almost all papers in the sections IV, VII and VIII are by German authors. All papers are in English. The volume is well produced and the photographic illustrations, several of them in colour, are reproduced on art paper. 228 NORTHEAST LIBR'^'''^ p'''">fMn CO. INC.
