Success or failure depended not on the activity of one institute alone, but on the general interest, goodwill and active co-operation of all embryologists the world over." With these words Dr.P.D.Nieuwkoop started the Introduction to the first issue of this periodical in 1949. Now, more than 30 years later, this international activity of the Hubrecht Laboratory is coming to an end. As we have already written to the institute correspondents the present issue is the last one to appear. The main reason for our decision to stop pioblication is the steady decline in the number of subscriptions. An additional reason is that it has become increasingly difficult for the Hubrecht Laboratory to invest the necessary manpower in the periodical (the cost of personnel was never calculated in the subscription price) . A number of subscribers have written to us, expressing their regret or offering suggestions on how publication might still be continued. We are thankful for these reactions but no feasible solution has presented it- self to us. The first issue listed 690 names, the last volume some 3.400. The number of co-operating institutes rose from 245 (in 28 countries) to more than 1.200 (in 50 countries). Since 1949 more than 1.500 book reviews and book notices were published, most of which were written bij Dr.J.Faber. It is perhaps natural that in these days of improved communication and exchange of information there is less need for a publication of this kind than there was just after the second world war. We are glad to know that the publication served a useful function for the international community of developmental biologists, and we know we are saying this also on behalf of Prof .Nieuwkoop. We express our sincere thanks to all those numerous scientists who over the years enabled us to maintain the service by regularly submitting data on their current research. We thank our com- petent secretaries for their conscientious work, particularly Lidy Ekelaar, who served the periodical for the last 15 years. Finally we want to say that we as editors have always performed our various tasks with pleasure.

Scientists were asked to state their name, degree(s), address, and research subjects in so far as recent, unpublished work in developmental biology was concerned.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. 17 were confirmed by the scientists still to be correct. Entries without research subjects: a. Persons Usted on the sheets as being engaged in research in developmental biology, without further specification of subjects. b. Persons with a complete entry in vol. 17 who have not returned their sheets. Name, degrees, and addresses were reprinted unchanged from vol. 17 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 Usted nevertheless; cases in point are several I.S.D.B. members. e. Persons listed in vol. 17 whose death has come to our attention (marked t). Persons listed in vol. 17 but not in vol. 18: a. Persons who had research subjects in vol. 17 but are not longer engaged in research in developmental biology. b. Persons who had no research subjects in vol 17 and have not returned the sheets for both vol. 17 and 18. The abbreviation Ms. in names stands for Miss or Mrs. In the research subjects, the following abbreviations have been used: ATP: adenosine triphosphate Animal names BUdR: 5-bromodeoxyuridine cAMP: adenosine-3', 5'-cyclic monophosphate Cat: cDNA: complementary DNA Chicken: cGMP: guanosine-3', 5-cychc monophosphate Cow: CNS: central nervous system Dog: DNA: deoxyribonucleic acid Horse: e.g.: for instance Man: EM: electron microscopy Mouse: GTP: guanosine triphosphate Pig: incl.: including Quail: lUD: intrauterine device Rat: LM: light microscopy Rabbit: mRNA: messenger RNA Sheep: NS: nervous system part.: particularly RNA: ribonucleic acid rRNA: ribosomal RNA SEM: scanning electron microscopy spec: species (singular) spp.: species (plural) tRNA: transfer RNA TEM: transmission electron microscopy t.s.: temperature sensitive UV: ultra-violet Fehs domestica (Carnivora) Callus gaUus domesticus (Aves) Bos taurus (Artiodactyla) Canis familiaris (Carnivora) Equus caballus (Perissodactyla) Homo sapiens (Primates) Mus musculus (Rodentia) Sus scrofa domesticus (Artiodactyla) Coturnix coturnix japonica (Aves) Rattus norvegicus (Rodentia) Oryctolagus cuniculus (Lagomorpha) Ovis aries (Artiodactyla) 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 1980. Older information concerning such Insti- tutes may be found in previous issues.

BROWDER, 1980, DEVELOPMENTAL BIOLOGY Saunders, Philadelphia.

It seems that the market for developmental biology texts is still not saturated. This latest addition, written for advanced undergraduates, is a 167 solid, well-organised text, yet I was curiously disappointed by it. The book is crammed full of factual material, most of it up to date and well repre- sented, but the conceptual scaffolding is rather scanty. The emphasis is on the control of gene expression as an explanation of cell differentiation, but the author seems to shy away from equally important global control mech- anisms such as morphogenetic fields and positional information. No theories of pattern formation are discussed except in a cursory way in relation to limb development at the very end of the book. "Field" is not even an entry in the subject index. The book presents an integration of comtemporary research with the classi- cal literature and includes some material on plant development, notably in chs.2, 7, 8, 9 and 12. Ch.l3 considers four different systems to exemplify organogenesis: epithelio-mesenchymal interactions, the lens system, hemato- poiesis, and the limb. A didactically interesting feature is the discussion of important procedures, processes and systems in seven boxed-in sections separate from the main text. Parts of the manuscript were reviewed by some two dozen North-American developmental biologists. All chapters have long reference lists which fully document the text and thus exceed the usual lists of further reading. The book is profusely and beautifully illustrated; a large proportion of the figures are photographs and electron micrographs. 2. L.GALLIEN. 1979.

Gastrulation et stades initiaux de la morphogenese chez les deuterostomes (8) The back cover of this book says that the text is intended as an "intro- duction to the experimental investigation of developmental biology". This is only true inasmuch as it prepares the student for other books. There is almost no experimental embryology in it, and only a little chemical or mo- lecular embryology. For the rest the approach is strongly descriptive. The book reads as Part one of a more comprehensive text. Another feature of the book, which is perhaps typical of French texts, is that the author carefully restricts himself to what is considered as the "classical" body of knowledge and seems to avoid more controversial and recent issues. Moreover, he makes some generalisations (e.g. on the "germ line" VS. the "soma") which today are difficult to uphold. The book is good on the classical subjects but lacks stimulus for the student of today. 3. A.MONROY and A.A.MOSCONA. 1979.

Regulation of DNA synthesis and gene expres- sion in the embryo, 7. Cell organization in embryonic morphogenesis, 8. Cell aggregation: construction of multicellular systems from cell suspen- sions This book is a strange hybrid and it is not clear for which readership it is intended. This is probably due to the fact that it arose from a series 168 of lectures delivered to a very mixed audience. Its hybrid nature will be apparent from a quotation from the preface: .... "it should serve as an up- to-date introduction for beginners and as a guidebook for graduate students and teachers to some of the issues, answers, and challenges in developmental biology". No book can be expected to serve this dual function. The authors concede that their approach is selective (and in fact it largely reflects their own special fields of enquiry) , but this is incompatible with the re- quirements of an introductory text. There are far too many gaps in the coverage. This is not to say that what there is is bad. Most of it makes interesting reading for more advanced students and for newcomers to the field. In chapters 2-6 the emphasis lies on molecular-genetic control mechanisms, in the remaining chapters on cellular events. The book is attractively turned out and very well illustrated. The litera- ture in the extensive chapter bibliographies rarely goes beyond 1976. 4. S.B.OPPENHEIMER. 1980.

Cancer and embryology This text for undergraduates has much to recommend it. It is clearly written and logically arranged, with structural facts coming first and mechanisms only later (particularly molecular mechanisms) . The reading lists are good and the key terms printed in the margins and the glossary are useful learning aids. Although the treatment is up to date in many areas (e.g. the role of the cell surface) a major criticism is that this does not hold for all areas: cases in point are the formation of the mesoderm in amphibians and amphibian limb regeneration. The lay-out of the book is attractive; the illustrations consist of simple but effective line drawings and very good photographs and scanning electron micrographs. In the reading lists there are some annoying misprints in authors' names. Monographs 5. G.P.KOROTKOVA. 1979.

It is salutary for embryologists and others to be reminded from time to time that develop- ment is not the outcome of the genetic programme inscribed in the DNA, but that the egg is the decoding machinery for the tape that is the genetic code (paraphrased from Jack Cohen's thoughtful introductory chapter). Cohen even advances the possibility that the embryo essentially inherits the code and the decoding machine separately and in parallel (even if the mother's code contains some of the instructions for building the tape player) . "To under- stand the first steps of morphogenesis we must understand not only the code but also the decoding machine", and that is where maternal effects can help us considerably. All of the 17 reviews in the volume are interesting. No discussions are recorded. There is much emphasis on the amphibians and mammals while Droso- phila is somewhat underrepresented with one paper on pole plasm. It is a pity that only a few papers have summaries. The volume is adequately illus- trated. 7. S.SUBTELNY and I . R. KONIGSBERG, eds. 1979.

The meeting was well planned and the con- tributions are almost without exception highly interesting and readable re- views of recent work; some of them make exciting reading. The 10-page pre- face by the second editor is in fact a thoughtful summary of the symposium. The 14 chapters are arranged in three sections as follows: Cytoplasmic localization in early development (6) ; Maternal effect mutants of development (3, of which one on nematodes); Pattern formation in developing systems (5, of which one each on ciliates and blue-green algae) . The volume is well produced and has a profusion of good figures. 8. S.SUBTELNY and I.M.SUSSEX, eds. 1978.

It was a good idea of the Society for Developmental Biology to devote this symposium (held in Raleigh, N.C. in June 1977) to what is essentially an 170 inventory of our present knowledge of clones in development. The difficult question of how clones relate to fields remains largely reserved for the future . Most of the 13 reviews discuss clones, or the possible role of clones, in Drosophila (3) , mammals (2) and plants (4) , as well as nuclear and genetic events in clone initiation in man and plants (one each) . Two contributions appear to have little or no relation to clones: that by Bryant on pattern regulation in amphibian limbs, and that by Green on the control of gene ex- pression by insertion mutants in Drosophila. The volume is well produced and illustrated. THEORETICAL AND MATHEMATICAL DEVELOPMENTAL BIOLOGY Monographs 9. I.LAMPRECHT and A.I.ZOTIN, eds. 1978.

Six con- tributors belong to the former institute and 15 to the latter. Most authors are adherents of the global approach to non-linear irreversible processes based on the Prigogine-Wiame theory. Prior to publication the subject matter was subjected to extensive discussion in various meetings in Russia and East and West Germany. In their preface and concluding remarks the editors are careful to point out that this area of study is still in its infancy. The main aim of the book is to reveal basic problems and to summarise first results. The latter are confined to studies by the authors which are still in progress.

It is in five main parts: General principles (genetic basis, information transfer, plant hormones, external factors); Cell division and growth; Cell expansion; Morphogenesis; Specific steps in differentiation. The last- of these covers more than a third of the book and has 10 chapters on diverse subjects including rest periods and activation, regeneration, turnover, gametogenesis, fertilisation and em- bryogenesis. The book is well illustrated and has a list of modern supplementary reading covering some 15 pages in small print and arranged by chapters. A suggestion for a second edition would be the inclusion of a list of abbreviations and a brief glossary of scientific terms. 171 11. W.P.JACOBS. 1979.

Overview The aim of this new text for undergraduates and beginning graduates is to describe the hormones of vascular plants and to discuss the ways in which hormones control and coordinate development. Consequently the emphasis is strongly physiological and cell differentiation and morphogenesis are not treated in their own right. The historical development of ideas is described at some length. The author's approach is critical, as reflected in his choice of only "sound" papers as references and in his extensive treatment of crucial research procedures, coupled with often very valuable advice to the student. The book is illustrated with clear line drawings, diagrams and graphs and has a bibliography of more than 800 titles and a brief list of books and reviews for further reading. 12. T.C.MOORE. 1979.

Phytochrome This book was written primarily for students but can also be useful to other readers. From the textbook perspective it presents the subject as a factual baseline, with relatively more emphasis on biochemistry than on physiology and without extensive discussion of hormonal interactions and other complexities; the author's experience is that this is the best format for graduate courses. The text is fluently written and fully documented in the lengthy chapter bibliographies, which moreover contain material for additional reading (it would have been better if these two classes had been listed separately) . The book is produced with great care and illustrated with excellent line drawings, diagrams and photographs. 13. I.K.ROSS. 1979.

This stimulating text for undergradu- ates would seem ideally suited to bring developmental biologists of other specialisations up to date, the more so as it includes the slime moulds though these are nowadays no longer placed with the fungi. 172 Of the three major parts that on development and regulation is of most direct interest to our readers. It occupies the middle third of the text and has chapters on spore germination and the thallus, on vegetative and sexual behaviour, and on multicellularity in ascomycetes and basidiomycetes , with a separate chapter on morphogenesis in the slime moulds. The informa- tion assembled in these chapters is quite up to date as textbooks go, al- though pattern formation in Dictyostelivm is not treated. The book is attractively produced and very well illustrated. INVERTEBRATE DEVELOPMENT (general) Treatises 14. H.FRIEDRICH. 1979. NEMERTINI Fischer, Jena.

One volume consists entirely of line drawings by the author. These are diagrammatic, often 3-diraensional, and usually very clear. Their aim is to convey the spatial configurations that are so difficult to glean from serial sections. They are conveniently ar- ranged according to organ systems. The most common developmental anomalies are also shown. The other volume contains the text in tabular form. It closely follows the illustrations, is written in "telegram style" and contains a surprising amount of information, clearly laid out. It is clear that the book has arisen from considerable teaching experience. It is concluded by a list of selected references arranged mainly according to organ systems. 18. D.J.BEGLEY, J. A.

Because of its emphasis on mechanisms rather than structure the book has a "modern" flavour often absent in books for beginning medical students. Moreover the style of writing is such as to hold the attention of the reader. Understandably, the strictly embryological chapters (embryogenesis and organogenesis) cover only about 20% of the book and consequently provide only the bare minimum of facts. Nevertheless, also there basic mechanisms are duly emphasized. In addition there are chapters on implantation, the structure and function of the placenta, reproductive failure and wastage (including congenital malformations and teratogenesis) , and maternal and fetal physiology. The illustrations are simple but effective. The reading lists, though very brief, are well selected. 19. G. -H.SCHUMACHER. 1979. EMBRYONALE ENTWICKLUNG DES MENSCHEN. 4th edit.

M 10.00 That a new edition of this book was required two years after the previous one (1977) shows how popular it is, particularly in East Germany. It has 174 gradually developed into a text suitable for university teaching. The present edition is much longer than the 3rd and has many more illustrations, part of them using colour for greater clarity. The contents have been rearranged to form two major parts, the first of which has been particularly expanded for this edition: General embryology (including reproduction, early development, placentation and teratology) , and Specific embryology (special organogenesis) . New additions are a brief historical chapter and a glossary of Latin and Greek terms with their plural forms and genders. Symposium reports 20. F.NAFTOLIN, ed . 1978.

Fetal-placental growth-A (Alexander, Greengard, Hill), IV. Fetal-placental growth-B (Meschia, Novy, Benirschke) The Dahlem Konferenzen are meetings without formal lectures. A number of background reviews are circulated in advance and discussed at the meeting. The published report contains the background papers and Group Reports drawn up by a rapporteur. The present meeting was held in Berlin in February 1978. It brought to- gether an international group of 40 embryologists , cell biologists, perina- tologists and others, which made for unique interdisciplinary interaction. The section of most immediate interest to mammalian embryologists is the second one, which covers 5 3 pages. Here the participants in the group dis- cussions were Beier, Bernfield, Caplan, Friesen, Gardner, Gropp, Habedank , Lindner, Neubert, Sara, Skalko and Solomon, with Nathanielsz as rapporteur.

There are also five general discussions on specific topics at the end of the book. The participants came from the USA, the UK, Australia and various Western European countries. The 15 con- tributions are up-to-date progress reports and reviews which together cover almost all conceivable aspects of the problem. Much attention goes to delayed 175 implantation and embryonic diapause. Two papers are of more specific interest to embryologists : that by Enders and Schlafke on comparative aspects of blastocyst-endometrial interaction, and that by Sherman et aZ. on changes in the blastocyst surface at implanta- tion. The book is neatly turned out and well illustrated. 22. P.MAULEON et at. , organisers. 1979. IVth WORKSHOP ON THE DEVELOPMENT AND MATURATION OF REPRODUCTIVE ORGANS AND FUNCTIONS Inst.

Although it is predominantly of interest to members of the medical profession, it merits to be briefly reviewed here. The large majority of the 42 contributors are Americans working in biomedical institutes. Most of the 22 papers are progress reports of a strong clinical slant, and only a few describe data obtained in animals. An interesting historical paper by Gordon is followed by an introductory review by Grumbach that bears the same title as the book.

The subject is of considerable theoretical and practical in- terest to developmental biologists who work on the regulation of gene expres- sion. Although this book was written mainly for oncologists, several chapters will be useful to mammalian erabryologists . This holds particularly for the review by Solter and Damjanov on teratocar- cinoma and the expression of oncodevelopmental genes. There is another chap- ter on teratocarcinoma-derived cell lines stabilised by SV40 transformation, by Levine. The chapter by Hirai deals largely with alpha-fetoprotein in both normal ontogeny and cancer. The remaining seven chapters are either predomi- nantly clinical or methodological in nature.

DM 368.00, $ 202.40 This atlas, by a Hungarian and two West-German authors, is based on the study of 190 embryos and fetuses ranging mostly from 3 to 28 weeks of age. The introduction surveys the whole period of extraembryonic and embryonic hemopoiesis. The actual atlas is in three parts: Diffuse hemopoiesis. Intra- vascular hemopoietic cells and Organ-bound hemopoiesis. A brief text accom- panies the plates in each of these. An attempt was made to identify differ- ent types of hemopoietic precursor cells that may represent early progenitor cells or indeed stem cells. The histological, . cytological and E.M. pictures in the plates are of superb quality and many of them are in colour. There is a bibliography of 65 titles. The book is sumptuously produced. 29.

M. 125.00 This book is the product of many years of research by one of Russia's leading neuroanatomists , one-time head of the Laboratory for Neuronal Structure of the Brain, Academy of Medical Sciences, Moscow. It is an ex- haustive, systematic description and interpretation of cortical neuronal structure based on several thousand Golgi series of ca. 200 embryonic and fetal brains from the 2nd month of development. The discussion is based on an original classification of neuronal shapes. The book is illustrated with a host of meticulous pen-and-ink drawings of neuronal shapes. A loose table summarises the author's "genealogical tree" of the neurons seen in the neocortex. The book is produced with great care. It has a bibliography of 130 titles. 30.

Neurochemical studies (2) This collection of short review and research papers arose from an inter- national conference held in Crete, Greece in September 1978. It is a book for the specialist and it is difficult to discern a central theme. By far the majority of the papers deal with postnatal mammals. In section V the following papers may be of interest to embryologists : Fraser on neuroplasticity in Xenopus , Bunt et al. on nerve fibre guidance mechanisms and polarity control in visual projection, and Rubinson and Kennedy on the organisation of the optic tectum in the lamprey. Of the two papers in Section VI one deals with the cholinergic system in the chicken retina and the other with enzyme development in dissociated chick embryo brain cells. The volume is well printed and adequately illustrated. 33. J.V.RUCH, organiser. 1979. TOOTH MORPHOGENESIS AND DIFFERENTIATION; an in- ternational workshop Edit. S.N.P.M.D., Paris. Journal de Biol.

Its publication in book form will be welcomed by all those interested in tooth development and by many other morphogeneticists as well. Some of the more theoretically oriented papers (particularly those by Butler, Osborn and Lumsden) are interesting because, despite certain controversies, they provide a good overview of the problems of pattern formation in a system that is not usually treated in books on that subject. The 33 contributors are from France, various other European countries, Israel and North America. The 20 papers vary greatly in format; some are brief research reports, others longer review-like or theoretical accounts; all have summaries in three languages. A variety of animal forms are dealt with, and many sophisticated methods applied. The 15-page introductory paper on epithelial-mesenchymal interactions is by Slavkin. The book is well produced and has beautiful illustrations. 179 CELLULAR DEVELOPMENTAL BIOLOGY (incl. cell culture, cytochemistry) (see also 8,28,29,32,38) Monographs 34. K.N.PRASAD. 1980.

Some as- pects of development of nervous tissue (34) This monograph is a useful summary of an important field. However, the fact that the chapter bibliographies very rarely go beyond 1976 means that several recent advances are missed out. A case in point is the recent work on the neuroblastoma plasma membrane and cell cycle. Chapter 1 contains a useful description of the amphibian neural induction system and of the six major in vitro techniques in use for nerve cells. Ch.4 discusses, among other things. Nerve Growth Factor, serum requirement and various hormones. Some of the aspects dealt with in ch.6 are morphogenesis, cell recognition and adhesion, neuronal death, locus specificity (for some reason discussed under the previous heading!), and neuronal plasticity. The book is illustrated almost exclusively with graphs and diagrams. Symposium reports 35. A. S.G.CURTIS and J.D.PITTS, eds . 1980, CELL ADHESION AND MOTILITY Cambridge Univ.

Of the 18 papers 11 are by authors or groups from the U.K., three from North America, and four from Poland, Sweden and Switzerland. Most of them are longish reviews while a few are more restricted in scope. They deal with physico-chemical principles of cell adhesion and with adhesion and motility in a variety of cell types. The two papers of most direct interest to our readers are that by Gerisch et al. on cell adhesion in slime moulds and that by Barondes on developmen- tally regulated lectins in slime moulds and chick embryos. Other papers deal with histocompatibility systems, cell surface glycoproteins such as fibronectin, and cytoskeleton-raembrane interactions. The book is very well produced and illustrated and has a very detailed index. 180 36. S.HATANO, H.ISHIKAWA and H.SATO, eds . 1979. CELL MOTILITY: MOLECULES AND ORGANIZATION Univ.

Although its chief concern is not developmental the subject is of ob- vious importance to developmental biologists. The original conference manus- cripts were extended by review material and the results of the conference discussions were incorporated, so that the book is useful as a reference source. The 43 chapters are arranged in five parts as follows: Actin , myosin and regulatory proteins (12 papers); Cinematographic demonstration of cell motility (6) ; Cell movement (7) ; Distribution and localization (8) ; Cell division (10). The six chapters of immediate erabryological interest are con- fined to sea urchin eggs (cytokinesis and microvillus formation) ; their authors are Mabuchi , Spudich et at., Kane, Hiramoto, Kojima and Nakashima, and Mohri. The volume is beautifully produced and illustrated. 37. N.LE DOUARIN, ed. 1979. CELL LINEAGE, STEM CELLS AND CELL DETERMINATION North-Holland, Amsterdam, etc. INSERM Symposium No. 10.

The resulting volume is somewhat heterogeneous and some contributions seem out of place. The format of the papers varies widely and very few have summaries or conclusions. Neverthe- less, there is much of value in the book since all papers deal with very recent work either in review form or as research reports. No discussions are recorded. Almost all papers in the sections on Segregation of cell lines (8) , Mouse teratocarcinoma(6) , and Stability of the determined state (9) are of (sometimes considerable) interest to embryologists . The remaining section on Blood-forming cell systems (10 papers) is somewhat difficult to assess for the non-specialist. The book is well produced and illustrated but has no subject index.

Most of the 48 papers are brief to medium-length mixtures of review and recent research 181 material, and most are followed by group discussions (without references or illustrations). Most of the material relates to man, various mammals, and the chick. The table of contents above speaks for itself. The book is printed on art paper and adequately illustrated. The subject index is rather short and an index to contributors is lacking. DEVELOPMENTAL GENETICS, EVOLUTION (see also 5,6,23) Monographs 39.

The chapters average some 40 pages in length and are well organised. All authors are Americans. The chapter that appears of most general interest to our readers is the first, by Paigen, entitled Genetic factors in developmental regulation. It devotes much attention to the intriguing class of genes called temporal, and assumed to be involved in the developmental programming of the activ- ity of other genes. In a separate section on horaeotic mutants it suggests a speculative model for imaginal disc differentiation based on hypothetical intradisc differentiation hormones and receptors. Other chapters worth mentioning here are that by Scandalios on the con- trol of gene expression and enzyme differentiation, that by Ho on the hor- monal control of gene expression, and that by Scott on biochemical-genetic control of morphogenesis in fungi and cellular slime moulds.

The format of the 31 papers varies widely and there has been minimal editing; many papers lack summaries. Most papers report on results that were new in 1978. Mammalian embryologists and general developmental biologists will find much of interest in the book. Most of this is to be found in the first two sections, which deal respectively with Developmental potency, gene expres- sion, control of phenotype and tumour origin (9 papers), and with Gamete 182 differentiation, sexual development and origin of the germ line (7 papers). The remaining sections deal with X-chromosome inactivation and repression (7) , X-chromosome non-randomness (5) , and Mathematical and statistical anal- yses of mosaic patterns (3) . The volume is well produced and adequately illustrated. 42.

The original discussion papers by 13 German, one English and one Danish author have been enriched with the results of the discussions. The papers vary greatly in lenght and are in English (11) or German (4), but all have summaries in the other language. The purpose of the symposium was to confront the thinking of morphologists and developmental physiologists on a common evolutionary basis. The range of subjects covered is extraordinarily broad, covering such subjects as cleavage, cell lineage, mesoderm formation, induction and metamorphosis, all in various animal forms. The volume is well printed and illustrated. DEVELOPMENTAL PHYSIOLOGY (incl. endocrinology, immunology, behaviour, etc.) (see also 22,25) Monogr'aphs 43. H.PARVEZ AND S.PARVEZ, eds . 1980.

Df 1.198.00, $ 96.50 This collection of papers by an international group of specialists deals with the biogenic amines in their function of neurotransmitters, not with their role in processes such as cytoplasmic movement. The 28 chapters are partly reviews and partly research reports, while some are mixtures of the two. They deal primarily with fetal and postnatal mammals but several chap- ters consider non-mammalian vertebrates as well. Chapters of potential interest to mammalian developmental physiologists are found mainly in section I (Physiology of biogenic amine development, 9 chapters) . The other sections deal with endocrine factors and neurotrans- mitter development (5 chs.), with environmental and genetic factors (5 chs.), and with studies relevant to the development of behaviour (8 chs.). The book was produced direct from typescripts and is well illustrated. Symposium reports 44. G.W.SISKIND, S.D.LITWIN and M.E.WEKSLER, eds. 1979.

Of the 13 papers the majority focus on the B-cell system. Further- 183 more there are three papers on ageing as related to immune phenomena, as well as one each on the regulation of Natural Killer Activity, on induction of antibody formation in the newborn, and on alpha-fetoprotein induction of immune-suppressive activity. Most papers are followed by discussions trans- cribed from tape. The illustrations are confined to diagrams and graphs. METHODS Monographs 45. J.C.DANIEL, Jr., ed. 1978.

It is obvious that this is one of those books that no mammalian embryo- logist or experimental morphologist can do without. All chapters are written by outstanding specialists and the book is a mine of information, and well illustrated into the bargain. It is only marred by the fact that most bib- liographies were already somewhat dated at the time of publication, and by an inadequate index.
