The Subject Index of this part refers to the research subjects of European investigators only. Part 2 will contain the data on investigators in all countries outside Europe, and will be organised in the same manner as part 1 . In the research subjects the wording used by the investigators was generally retained, but some changes have been made in order to save space. Repetitions of words and parts of entries giving too much detail were omitted; phrases such as: "research on . . ." or "studies of . . ." were cancelled; often methods were put in brackets at the end of the entry. Inevitably these condensations have caused a certain loss of information, but we feel that clarity is not seriously impaired. For the names of higher taxa of experimental animals the following books have been consulted: L. A. Borradaile and F. A. Potts, The Invertebrata (4th ed., 1963), and J. Z. Young, The Life of Vertebrates (2nd ed., 1962). Lord Rothschild, A Classification of Living Animals (2nd ed., 1965) was also of much use. Generally the highest taxon given at the end of the entry is the class, but in Angiosper- mae it is the family, in Mammalia, Reptilia, Amphibia, and Insecta the order, while in Crustacea and Arachnida both the class and the order are listed. Some changes have been made in the Subject Index. In previous issues all the work on plants and on unicellular organisms was brought together under one Heading each, whereas the other Headings served multicellular animals only. Starting with this issue plants and (other) unicells are treated in the same way as Metazoa; see the list of New Headings on page 137. The number of Subject Headings has been augmented by using some of the former cross references (see) as Headings in this issue. Since the G.E.I.S. covers a much wider field of developmental biology than embryo- logy alone, the title of the periodical might be considered inadequate or even confusing. We felt, however, that a well-known title should rather not be changed, and therefore added an explanatory subtitle: An international directory of current research in develop- mental biology . For many years the number of research workers listed in the Directory of Names rose at a rate of about 10 percent every two years. From volume 15 (1973/74) onwards the increase has been no more than 3 percent. We think this decrease reflects a stagnation in the growth of research facilities in many parts of the world. Also the number of books on developmental biology published in one year is no longer increasing. We feel this is the place to say a few words about the Enquiry on the utility of: Cen- tral Embryological Library (CEL) and General Embryological Information Service (GEIS), which was held in October 1976 and proved to be a success thanks to the co-operation of many developmental biologists. Forms were sent to the 3,200 persons listed in volume 16 of the GEIS, of whom about 35 percent responded by returning completed forms, often supplemented by valuable remarks. In general the outcome of the enquiry was very positive. Here we only mention the results on the GEIS, but those on the CEL were equally encouraging. The analysis of the results show that exactly half of the responders use the GEIS; in- formation in every section is consulted by more than 80 percent of the users, while 90 percent of them are reasonably to well satisfied with the information supphed. This result encourages us to continue publishing the periodical in its present form. However, the financial situation is a cause for concern. On the one hand the production costs are still rising, while on the other hand more and more scientists in various coun- tries apparently can no longer afford to pay the increasing subscription rates. An increasing number of subscribers are in arrears. We hope to be able partly to alleviate the rise in production costs by the use of type- script offset and by computer-aided processing methods. Although the interest shown by developmental biologists through the Enquiry is encouraging, a constant and sufficient number of paying subscribers remains the only basis on which we can continue the Service.

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 Hsted 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 listed 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. ABERCROMBIE, M. - Strangeways Res.

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 a rule not listed, with the exception of the names of Institute directors. (*) Asterisks 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 asterisks, this usually means that no information has been submitted by the Institute in 1977. Older information concerning such Institutes may be found in previous issues. EUROPE AUSTRIA Graz, Zool. Inst, der Univ. FACHBACH, G. Salzburg, Osterr. Akad. der Wissensch., Inst, fur Mol.

All research subjects in the Directory of Names and Addresses are represented by at least one entry. The names of investigators refer back to that Directory. Headings are printed in capitals. New headings are listed on the next page. Headings generally come under one of the following categories: 1) Structures, e.g. organs, tissues, cells 2) Substances or classes of substances 3) Developmental stages, processes, and factors (including metamorphosis, regeneration, developmental genetics, reproduction, developmental pathology) 4) Techniques appearing as headings are: Chemical microanalysis. Culture & preservation, Immunochemistry, Irradiation, Microcinematography, Rearing methods. Transfer (Blastocyst, etc.), Transplantation, Ultraviolet Irradiation, Vital staining, X-Irradiation. Other techniques will be found as subheadings (see below). 5) General subjects: History, Theoretical biology. Headings are extensively cross-referenced, but not usually from lower-order to higher- order categories. Subheadings Headings having less than ca. 1 0 names of investigators usually lack subheadings. The same research subject may be listed more than once under the same heading, e.g. under a structure and a technique. Subheadings come under one of the following categories: 1) Entities subordinate to the heading 2) Entities related to the subject of the heading 3) Techniques, discipUnes, and processes. These are often chosen from the Ust appearing on the next page; some of these terms are also used as headings - the resulting redun- dancy is unavoidable; it is considered rather an advantage because it provides several entrances to the same subject. 4) Developmental stages; see the list on the next page. 5) Links with other entities, such as "effect on . . ., effect of . . ., interactions with . . .". Animal and Plant Names Throughout the index Classes (and in some cases Phyla) are used exclusively. Excep- tions are: the use of Homo for work on the human species, and the use of Orders under some general headings: Development (general). Development (larval). Development (post- embryonic, fetal), Embryology (general & descriptive), Embryology (physiological), Life cycles. Regeneration, Reproduction. Those who are looking for work on a specific taxonomic group are advised to start with the headings of a general nature, such as Asexual reproduction. Development, Embryology, Life cycles. Metamorphosis, Morphogenesis, Regeneration, Reproduction, etc. Names of in vestiga tors In the case of work carried out jointly by two or more investigators, all collaborators are Usted in alphabetical order. Since initials of first names are omitted from the entries, it may sometimes be necessary to check two or more investigators of the same surname in the Directory of Names. 136 Headings cancelled Plant embryology & morphogenesis Unicellular organisms New Headings Amitosis Mammary Gland Apical Dominance Meristems Cell Death Osmoregulation Cell Wall Parasitism Chalones Photomorphogenesis Cyst & Encystment Phyllotaxis Development (Plant: : general) Root Development (Unicellular organisms: Salivary Gland general) Seed (& Germination) Dormancy Sex Differentiation Egg Coverings Sex Reversal Embryology (Plant: experimental) Shell (body covering) Flower(ing) Shoot Free-martin(s) Silk Gland Fruit(ing) Spore (& Sporulation) Hermaphroditism Synapse Hormones (plant) Vascular Tissue Implantation Vitellogenesis Intersexuality Viviparity Leaf Subheadings often used ur, ider various headings Techniques and disci iplines Autoradiography Histology Biochemistry (incl. techniques) Histo-& cytochemistry Biophysics Immunology Culture in vitro Irradiation Cytology Microcinematography Descriptive study* Molecular Biology Endocrinology Morphology Enzymes Physiology Experimental study' t: Theoretical study Function Tracer study General study* Transplantation Genetics Ultrastructure Processes Development* Metamorphosis Differentiation Morphogenesis Functional differentiation Necrosis (cejl death) (maturation) Pattern formation Growth Pathology Induction Regeneration Involution (regression) Teratogenesis Malformations Stages Early stages Oocyte Egg Oogenesis Embryo Placenta Fetus Postnatal Larva Spermatogenesis Neonate These subheadings are also used when the available information was not detailed enough to use one of the more specific subheadings. 137 ABDOMINAL CAVITY Mammalia Bukulya Mammalia Choroszewska see Body cavities Gyevai Mankowska experimental study Safanda ABNORMALITIES Mammalia Mitskevich see Anomalies ( early develop- function AMITOSIS merit);

Their main aim is to provide an idea of the scope and potential usefulness of the books. All notices (unless signed) are written by the editor; if necessary he soUcits the opinion of the staff of the Hubrecht Laboratory or of other specialists. Dissertations, some research monographs, and other works of a very specialized nature or written in languages not generally known, are usually provided with brief annotations only. Various types of books are distinguished according to the following criteria: Treatises: large comparative or systematic works, incl. serial pubUcations Textbooks: incl. "readers", introductions, compendia, practical manuals, etc. Monographs: incl. collections of reviews, essays, atlases etc. Dissertations: academic theses Symposium reports: incl. reports of congresses, conferences, meetings, etc. Collections of papers: containing original research papers by various authors, or reprint- ings of papers by one author Books of readings: containing reprintings of papers by various authors Reference works: incl. glossaries, data books, source books, etc. CONTENTS The numbers refer to the serial numbers of the notices.

BERRILL and G. KARP. 1976. DEVELOPMENT McGraw-Hill, New York, etc. X,566 pp., 332 figs., 3 tabs., subject index. $ 15.95, £ 10.85 This text can be conveniently contrasted with Berrill's "Developmental Biology" issued by the same pubhsher in 1971 . The present book is more conventional in the arran- gement of its subject matter but the scope is similar and it is equally excellent in its way. Perhaps this book is more suitable for the usual type of developmental biology course. The treatment is beautifully balanced and integrated and the style is fluent and capti- vating. Equal attention goes to structural, cellular and molecular aspects, and the integra- tion of the organism is emphasised throughout. Examples from the world of plants are restricted. Special features are separate chapters on the immune system, malignancy, aging, metamorphosis, regeneration, and asexual development. (Two subjects that are conspicuously lacking are germ cell determinants and induction in the amphibian blas- tula.) There is a most useful brief appendix on the sophisticated modern methods in use today. The illustrations, many of which are the same as in the earUer book, are well chosen, have good captions, and are well reproduced. The reading Usts at the end of all chapters are excellent. C.F.GRAHAM and P. F. WAREING, eds. 1976. THE DEVELOPMENTAL BIOLOGY OF PLANTS AND ANIMALS Blackwell, Oxford, etc. XII, 393 pp., 238 figs., 33 tabs., combined subject and taxonomic index. £ 7.75 (paper) Contents (abridged): Part 1, The origin of cell heterogeneity in early development; Part 2, Determination and pluripotentiaUty; Part 3, Cell interactions in development; Part 4, Hormonal control of development; Part 5, The molecular biology of develop- ment; Part 6, Environmental control of development. (23 chapters) This is the first unified account of plant and animal development written for advanced undergraduate and graduate courses, at least in English. It was written by 20 predomi- nantly British authors, estabUshed authorities as well as younger people. The starting point in selecting topics was that they would be treated in depth rather than giving com- prehensive coverage at a general level; hence, topics were chosen both for their general bearing and for the amount of well-established information available on them. The editors have been very successful in integrating the chapters by introducing and summarising the 199 Parts and by extensive cross-referencing. Although there of course remain differences in style among the chapters, the result is a very readable and stimulating whole. The related- ness of plant and animal data is very well brought out throughout the text. Moreover, the treatment is as up to date as can be desired in such a collaborative undertaking. Of course there always remain grounds for criticism. In one of the areas with which this reviewer is most familiar, it has been obvious to him that the author of ch.3.6 (Pat- tern formation in animal embryos) is not intimately acquainted with amphibian embryo- genesis or its literature. This is most apparent in his neglect of mesoderm induction in the blastula, a phenomenon discovered by Nieuwkoop and others about a decade ago. (Al- though the chapter contains interesting ideas it is written in a rather out-of-the-way man- ner.) The same criticism applies to ch.3.4 (Embryonic induction), which has a somewhat parochial reference list; moreover, it uses the important notion of competence but fails to define it. The numerous illustrations, both photographs and drawings, have good captions and add greatly to the value of the text; some of the diagrams are feats of didactic clarity. The index is extensive. 3.

IV, 68 pp., 24 figs., 2 tabs. £ 3.00 (cloth), £ 1.50 (paper) This is a selective but useful survey of the very varied types of viviparity found in many vertebrate groups as well as invertebrates. Ovoviviparity is included because it can- not be distinguished reliably from true viviparity. The line drawings are very simple and often insufficiently labelled. There is a glossary pertaining to reproductive horm'ones and a useful reading list. 4. A. C. NEVILLE. 1976. ANIMAL ASYMMETRY Arnold, London. Studies in Biology 67.

However, it is too synoptic and too incompletely documented to perform a useful function for the re- searcher. It raises many questions but hardly begins to provide the answers. The illustra- tions are simple but adequate. 5. F. SEIDEL. 1975-1976. ENTWICKLUNGSPHYSIOLOGIE DER TIERE.

DM 19.80 (paper) The first part (1972) of this three-part text was reviewed in Gen. Embryol. Inf. Serv. 15,2, 1 974. The laudatory first paragraph of that review on the whole applies equally to the present two books, yet this reviewer feels more critical about them. The major subdivi- sions of the original book, which is now almost a quarter of a century old, have been retained, and because the incorporation of newer data has been erratic the books defini- tely impress one as somewhat dated. Although the presentation of the older data remains excellent, there are curious gaps in th'^ newer data. To mention a few examples: modern work on gradients in insects is 200 not represented; there is no mention of mesoderm induction in the amphibian blastula; the data on imaginal discs are mostly very old and data on homoeotic mutants are lacking: the information on polar granules in insects is scanty; and cellular metaplasia in amphibian lens regeneration is not mentioned. The selective reference list of some 260 titles reflects these and other gaps. The books are well illustrated and have good glossaries. Monographs 6. D. H. O'DAY and P. A. HORGEN, eds. 1977.

SFr. 130.00 Contributors: Dingle, Durston, Francis, Haber, Horgen, Johnson, Kochert, LeJohn, LeStourgeon, Loomis, Lovett, O'Day, Sutter, Thompson, Van Etten, Wright, Yuyama This volume shows convincingly how much primitive eucaryotic organisms are already contributing to the solution of several basic problems of development, and how great is their potential. It is a series of reviews of current research by predominantly American and Canadian authors, and can be recommended to all developmental biologists, including those preparing courses or books. The 17 chapters deal with a great variety of "microbes" (in a very broad sense): various unicellular organisms, a colonial alga, true and cellular slime moulds, and various fungi. The chapters are arranged in three parts, each preceded by a brief editors' introduc- tion which places them in a general perspective and facilitates reading by non-specialists. Part I (Growth and cellular differentiation, 9 chapters) deals with genetic analysis of development, transcription, and enzyme accumulation and function. Part II (Cell com- munication and morphogenesis, 4 chs.) discusses four different types of effectors: glyco- proteins, terpenoid and steroid hormones, and cyclic nucleotides. Part III (Dormancy and germination, 4 chs.) considers membrane behaviour, extracellular enzymes, and macro- molecular synthesis. The book is produced in good offset print but has relatively few illustrations, in view of which the price seems excessive. Books of readings 7. C. FULTON and A. O. KLEIN. 1976. EXPLORATIONS IN DEVELOPMENTAL BIO- LOGY Harvard Univ.

They have tried to make the book readable for students with one year of general biology and genetics. Although it is always possible to disagree about details of selection and omission, the present reviewer found their approach stimulating, their coverage admirable, and their editorial efforts on the whole successful. The six main sections listed above are subdivided into 22 chapters. In most of these the 201 papers range from the late fifties or early sixties to the early seventies. The oldest papers are those by Spemann and Mangold ('24), Waddington, Needham and Needham ('33), and DuShane ('35). The last main section has chapters on the genesis of neural connections and on autonomous growth in plants (crown-gall tumour). Most of the research papers are on current animal developing systems, but there are also papers on Lilium (anthers), Blas- tocladiella (spore germination), Dictyostelium (enzyme programmes), and various unicel- lular organisms and bacteriophages (self-assembly). Mammalian embryos are only con- sidered in connection with the clonal origin of melanocytes. The book is attractively produced. The editorial sections have their own very good illustrations.

Much of the material may therefore by now be superseded. We will content ourselves with briefly enumerating those contributions that might stUl be of interest to our readers. The first is a long article by Zeeman on primary and secondary waves in developmental biology. He applies the now much debated catastrophe theory to embryogenesis in amphibians and to slime mould culmination. Gierer and Meinhardt discuss pattern forma- tion involving "lateral inhibition" and outUne several possible biological applications. Blomfield (from Lawrence and Crick's group) presents a diffusion model of pattern formation in the insect cuticle. Finally Kopell and Howard discuss "pattern formation" in the Belousov (or Zhabotinskii) reaction, a non-biological oscillating system. 9. A. LINDENMAYER and G. ROZENBERG, eds. 1976. AUTOMATA, LANGUAGES, DEVELOPMENT North-HoUand, Amsterdam, etc. VIII, 529 pp., 147 figs. Dfl. 120.00, $ 46.00 This volume is the result of an international conference held in the Netherlands in the spring of 1975. In it took part biologists, mathematicians and computer scientists from many different countries, predominantly in Western Europe. Of the 38 contributions seven are reviews and the rest research reports. The papers are arranged in four parts as follows: Mathematical and computer models of development (12 papers). Theory of L systems (17), Cellular automata theory (3), and Parallel graph generating and related systems (6). Almost ail of the papers of direct devel- opmental relevance are to be found in part one. These cover not only branching systems in plants but also a variety of animal developing systems and growth phenomena gener- ally. Two or three papers in the other parts have some relevance to development beyond the strictly mathematical. Part four represents a very new field of research, which may be the first step towards the application of L systems in more than one dimension, in other words, to more complex patterns than those characteristic of linear branching structures. 202 PLANT DEVELOPMENT (general) (see also 2,6) Treatises 10.

Although conceived as an educational aid, it will also be very useful as a reference work for researchers, particularly because of the illustrations and the wealth of practical information it contains. Some 600 plant genera and species are described or at least mentioned in the book, all of them forms that are easily available in nature. The subject matter is arranged strictly taxonomically, beginning with the bacteria and ending with the angiosperms (forms lower than the spermatophytes occupy more than 80% of the volume). The mode of treatment is dictated by practical considerations and varies according to the relative emphasis on e.g. phylogenetic and ontogenetic viewpoints, wealth of forms, ecological relationships or economic significance. Most of the 30-odd subdivisions are preceded by a brief theoretical section, often including a review of the taxonomy and/or a determination key. All the illustrations are original. The main figures are either beautiful Une drawings or plates consisting of hundreds of mostly exceUent photographs taken with a variety of techniques. In addition, numerous good line drawings and diagrams in the page margins serve to clarify the text. The book is very cheap for its high standard of production. Textbooks 11. S. S. BHOJWANI and S. P.

There are now separate sections on api- cal dominance, bud dormancy, and photomorphogenesis. Some new illustrations have been inserted and the reading lists have. been updated. 203 Monographs 13.

Nucleic acids and protein synthesis in chloroplasts and mitochondria (Bryant); 5. The cell cycle (Bryant); 6. Molecular aspects of differen- tiation (Bryant); 7. Plant growth substances (Trewavas) This book is stated to be the first to deal specifically with this subject, and arose out of a much-felt need. It is written by a team of British experts and will be of great use to graduate students, research workers and lecturers. The last three chapters are of most immediate interest to our readers. Together they occupy 122 pages. Ch.6 is very selective and concentrates on examples that clearly illus- trate general principles and current hypotheses. Ch.7 is concluded by a new unifying hypothesis that relates the effects of plant growth substances to membrane physiology. All chapters are well written and adequately cross-referenced. All have a brief list of suggestions for further reading. The bulk of the references are brought together in a bibliography of close to 550 titles which runs far into 1975. The book is well produced and illustrated mainly with dia- grams and graphs. Much material is condensed into useful tables. 14. M. E. CONKLIN. 1976.

SFr. 75.00, DM 75.00, ca.S 29.00 (paper) The author of this monograph has been famiUar with the genus Datura for over 30 years. The book is a well-organised review of almost all that is known of the herbaceous species of this genus, with emphasis on the advances of the last 15 years. Of the 12 chapters we mention The Datura life cycle (26 pp.), Embryogenesis in vitro (8 pp.), Androgenesis and the production of haploids (1 1 pp.),//2 vitro culture of tissues or cells (3 pp.). Factors affecting growth and development (1 1 pp.). Abnormal tissue de- velopment and tumorisation (8 pp.), and Isozymes (7 pp.). The ontogeny of alkaloids is also reviewed. The book is scantily illustrated but has some good photographic plates. The biblio- graphy of over 400 titles runs well into 1974. 15. H. van den ENDE. 1976. SEXUAL INTERACTIONS IN PLANTS, the role of specific substances in sexual reproduction Academic Press, London, etc. VIII, 186 pp., 38 figs., 26 tabs., combined subject and taxonomic index. £ 7.80 Inasmuch as sexual reproduction involves the differentiation of sex organs and sex cells, the subject of this monograph belongs to developmental biology. The book is inten- ded as an introduction for students but will certainly be of interest to investigators. The author, who has worked in the area for a decade or more, devotes special attention to the molecular aspects both of hormone-mediated and cell-to-cell interactions. A lengthy introductory chapter places the subject in perspective and devotes consider- able attention to hormone receptors and ceU surface constituents in animal systems. The 204 rest of the book is taken up by a series of chapters of varying length which examine spec- ific groups or species separately: Fungi (3 chapters), yeasts (1), algae (4), ferns (1), and flowering plants (1). The book is well produced and has good illustrations, both line drawings and photo- graphs. The bibliography contains more than 350 titles and is up to date until early 1975. 16. M. LUCKNER, L.

DM 48.00, $ 21.20 The bulk of this book consists of an interesting review of some 80 pages by Luckner and Nover (Halle, DDR) entitled Expression of secondary metabolism- An aspect of cell specialization of microorganisms, higher plants, and animals. It deals with what may be broadly called differentiation programmes (with special reference to the formation of the enzymes of secondary metabolism), their effectors, and their temporal integration. Although the majority of the evidence reviewed is derived from microorganisms and plants, some animal examples are also discussed. The references from the international literature cover 20 pages and are up to date untU early 1976. The second review by Bohm (Halle, DDR) discusses the secondary metabolism of cultured plant cells and the problem of why these often fail to form secondary sub- stances. The bibliography of this article contains many recent publications in German. The book is produced in good offset print and is illustrated mainly with graphs. 17. V. RAGHAVAN. 1976.

The author has been actively involved in research in this field for over a decade and therefore writes with authority. Because he knows the whole literature he is able to point out the major (and indeed large) gaps that still exist in our knowledge. The book is in three sections, the first of which is entitled, From egg to embryo and occupies about three quarters of the book. The first five chapters review the structural, biochemical, growth and nutritional aspects of embryogenesis. The remaining six chapters then deal with in vitro studies, various aspects of the control of embryogenesis, and applied aspects of embryo culture. Section Two (62 pp.) deals with diploid and haploid adventive embryogenesis, and Section Three (46 pp.) with seed dormancy and germination viewed as a problem of the auto-inhibition of growth. An appendix lists 1 8 of the most commonly used media for embryo culture. The book is profusely illustrated with good line drawings and photographs (some of the electron micrographs are too darkly reproduced). The bibliography of close to 2.000 entries contains many titles in languages other than English and is up to date until 1974. 205 18. L. W. ROBERTS. 1976.

Epilogue This monograph by a distinguished authority examines the differentiation of one parti- cular cell type from as many angles as possible, with the emphasis on the cell biology of the process. The treatment is critical but not exhaustive; most of the attention goes to internal control mechanisms as against environmental factors, which are probably not critical variables. Because the author places his subject in the broad perspective of devel- opmental biology as a unified science, the book will be read with interest by zoologists. The table of contents speaks for itself. The bibliography numbers over 600 titles and goes into early 1974. The Epilogue is concluded by a 5-page section highlighting some recent developments, complete with references going into 1975. The book is well produced and illustrated mainly with very good photographs from many different primary sources. 19. H. SMITH. 1975. PHYTOCHROME AND PHOTOMORPHOGENESIS, an introduction to the photocontrol of plant development McGraw-Hill, London. XVI, 235 pp., 107 figs., 23 tabs. £7.95, $22.00, DM45.20 Although this book was pubUshed more than two years ago we briefly mention it for the benefit of our readers. The book has been well received in the scientific press. The term photomorphogenesis is taken in a narrow sense, excluding phototropism and photo- periodism. The former subject is nevertheless treated in some detail; the latter is not covered, and the reader is referred to a companion volume by Vince-Price ( 1 975), which was reviewed in Gen. Embryol.

MATHEMATICAL MODELS IN PLANT PHYSIOLOGY, a quantitative approach to problems in plant and crop physiology Academic Press, London, etc. XIV, 318 pp., 81 figs., 11 tabs., subject index. £ 9.80, $ 24.25 This book is concerned largely with quantitative approaches to plant growth and devel- opment, a fact which is not clearly brought out in the title. The author has himself contri- buted greatly to this area, as is apparent from the bibliographies. The author presents his "modelling philosophy" in the introductory chapter. Chapters 10-13, together occupying about a quarter of the book, are of most interest to our readers. They are entitled Development and senescence, a new growth equation; Unres- tricted vegetative plant growth, with senescence and transport; A biochemical switch, development, and flower initiation; and Primordial initiation and phyllotaxis. The model developed in the latter chapter uses polar coordinates and a morphogen and is related to Turing's early approach. Ch. 14 deals largely with the external form of plants and delibe- rately ignores temporal growth patterns as being at present too difficult. The book has a very useful glossary. 206 Dissertations 21.

P. CAPPUCCINELLI and J. M. ASHWORTH,eds. 1977. DEVELOPMENT AND DIFFER- ENTIATION IN THE CELLULAR SLIME MOULDS Elsevier-North Holland, Amsterdam, etc. Developments in Cell Biology, Vol.1. XX, 317 pp., 145 figs., 12 pis., 35 tabs., subject index. This symposium volume is a must for all those working on or interested in cellular slime moulds. The meeting was held in Sardinia in April 1977 and publication was thus extremely rapid. There were 70 participants from all over the globe, including many of the younger members of the "slime mould community". The 24 research reports and reviews of recent work range in length from about five to about 20 pages. Between them they cover almost all conceivable aspects of the develop- ment of these fascinating organisms, including membrane physiology, biochemistry, molecular biology and genetics. No discussions are recorded. The Editors' Preface contains a brief account of the basic biology of these organisms. Although there is not much unity in the book, it is extremely useful as a "cross section" of most of the work that is going on right now. The papers are reproduced from typescripts. They are well illustrated. 26. J. R. COLLIER, F. J. LONGO, R. L. MILLER and J. B. MORRILL, organizers. 1976. SPIRALIAN DEVELOPMENT Amer. Soc. of Zoologists, Thousand Oaks, Calif. American Zoologist vol. 16, 3. 352 pp., 308 figs., 24 tabs. This symposium was held in December 1974 and consequently part of the material may now be outdated. Nevertheless, it is very helpful to have much work prior to 1974 together in the form of a series of well-written and well-illustrated reviews. All contribu- tors but one were from North America, but one contribution is a joint American-Dutch paper. The material discussed pertains to a large number of different spiralian forms. The dis- cussions range from the morphological to the molecular-biological level. After a review of basic types of spiral cleavage the remaining papers are arranged in five sections as fol- lows: Gametogenesis and fertilization (5 papers); Experimental cytoembryology (6); Bio- chemistry of development (5); Larval development and metamorphosis (2); Regeneration and adult growth (2). The volume is profusely illustrated, predominantly with light and electron micro- graphs. 27. P. A. LAWRENCE, ed. 1976. INSECT DEVELOPMENT Blackwell, Oxford, etc. Symposia Royal Entomol. Soc.

That it was a didactic sym- posium is evident from the fact that all contributors have tried to write non-technically and have provided essential background material. The result is a collection of very readable reviews which clearly reflect the excitement engendered by the rapid flow of new data in this field. There is considerable overlap among some contributions but there are adequate cross-references. The first essay (by Schneiderman) is the longest and spans the entire field. Of the other contributions three deal with eggs and embryos, four with imaginal discs, and four with 208 pattern in later development (eye development, leg regeneration, the role of JH in pattern formation, and chromosome puffing and ecdysone). All papers are followed by brief dis- cussions which are often illuminating. Most reference lists go well into 1976. The book is very well produced and well illustrated with line drawings and photo- graphs. 28 H. M. McCAMMON and W. A. REYNOLDS, organizers. 1977. BIOLOGY OF LOPHO- PHORATES Amer. Soc. of Zoologists, Thousand Oaks, Calif. American Zoologist vol. 17, 1. 150 pp., 139 figs., 11 tabs. This symposium was held in August 1975. The Lophophorates are a loose group inclu- ding the Bryozoa, Brachiopoda and Phoronida. Of the 13 papers in this volume six deal in one way or another with descriptive aspects of the development of these organisms: embryonic, larval and postlarval development, colony development, and growth and dif- ferentiation of adventitious structures. All of these papers report on original research against a varying background of review material of a morphological or evolutionary nature. They are written by specialists from five countries and are very well illustrated with line drawings, photographs and micrographs. VERTEBRATE DEVELOPMENT (general) Treatises 29. B. LOFTS, ed. 1976.

Physiology of molting (Larsen); 3. Ground substance: an anuran defense against desiccation (Elkan); 4. The physiology of Amphi- bian cells in culture (Rafferty); 5. Immunity mechanisms (Cooper); 6. Pathology in the amphibia (Elkan); 7. The nervous system (Oksche and Ueck); 8. The visual system (Ingle); 9. The auditory system (Capranica); 10. The biology of metamorphosis (Dodd and Dodd) It is particularly the last chapter of this volume that is of special interest to develop- mental biologists. It is a well-organised and authoritative review, which moreover presents a new theory of thyroxine action in metamorphosis. Several other chapters (notably chs. 4,5,6 and 7) contain information of developmental relevance. ' Most of the chapter bibliographies are up to date until 1974. The book is well pro- duced and illustrated. 30. F. S. RUSSELL. 1976. THE EGGS AND PLANKTONIC STAGES OF BRITISH MAR- INE FISHES Academic Press, London, etc. XVI, 524 pp., 137 figs., 7 tabs., systematic and subject indexes. $ 19.50 Although this book by a great authority is largely a guide for the identification of early fish stages in ecological studies, it could be useful to fish embryologists as a refer- ence work and for its additional information. It is a definitive work. After a series of brief chapters dealing in a general way with such matters as the egg and its development, the larva, the postlarva, and feeding habits, 40 families are taken up 209 in succession. Each of these chapters has a general introduction and then proceeds to characterise one or more, sometimes many species. Apart from the illustrations, docu- mented information is provided for each species on some or all of the following topics: egg, larva, postlarva, food and feeding, rearing, growth rate, behaviour, and distribution. Strictly oceanic species and descriptions of young and fry are excluded. The book has a host of careful line drawings and a bibliography of close to 600 titles. Textbooks 31. P. CHIBON. 1977. EMBRYOLOGIE CAUSALE DES VERTEBRES Presses Univ. de France. Serie Le Biologiste. 224 pp., 54 figs., subject index This little book was probably written for advanced undergraduate students. It presents a highly selective outline of classical vertebrate experimental embryology, with rather much emphasis on the work of French embryologists. This is supplemented by chapters on the analysis of cell proliferation (the author's own speciality) and on cell death in morphogenesis. The book is well organised and clearly written. There are some odd omissions, how- ever, such as mesoderm induction prior to gastrulation and the role of the apical ecto- dermal ridge in limb development. The definition of'morphogenetic field" is rather nar- row, while other basic concepts such as epigenesis and morphogenesis are not defined at all. The line drawings and diagrams are helpful, but the few photographic illustrations are not very well reproduced. The bibliography is restricted to some 20 titles. The index is grossly inadequate. 32. L. HAMILTON. 1976. FROM EGG TO ADOLESCENT, Xenopus - a model for devel- opment English Univ. Press, London. XII, 78 pp., 34 figs., subject index. £ 3.45 It is difficult to form a judgement of this book because one would have to see it through the eyes of those for whom it is intended: English sixth formers and beginning students. It will certainly convey to them something of the excitement of scientific dis- covery; on the other hand it is perhaps too unbalanced and at the same time sometimes too difficult in its treatment to convey a really integrated mental picture. Embryology is a difficult subject, and it depends so much on correct (particularly spatial) mental images that the book may fall short particularly due to its pictorial limitations. Apart from this, the style is not always clear and there are some odd inaccuracies. I suspect many embryologists would agree that Xenopus is probably not unique among anurans in having internal prospective mesoderm. Some subjects get an inordinate share of attention (for instance cleavage), while others are not treated in sufficient depth to give proper understanding. Many more difficult words could have been explained in the glossary. The 40-odd literature references are well selected and the appendix describing some simple operations is very good. The line drawings are good and the electron micrographs are well reproduced. 33. W. W. MATHEWS. 1976. ATLAS OF DESCRIPTIVE EMBRYOLOGY. 2nd edit.

A brief chapter on human development has been added, as well as a 17-page chapter entitled Experimental embryology. This is entirely methodological in character; it suggests no specific experiments and does not discuss the results of such experiments. Dissertations 35. G. HENTSCHEL. 1974.

If the promise of the first two volumes is fulfilled it will develop into a real forum for the exchange of facts and ideas. Moreover, publication is extremely rapid as books go. Contri- butions will be both by invitation and submission, and no rigid format is prescribed. This is exactly the sort of thing that a rapidly developing area of science needs. For vol.3 the editor particularly seeks contributions on sex determination and differentiation. The 17 reviews in the first two volumes, with an average length of 35 pages, concentrate on peri-implantation stages and blastocyst-uterine relationships. Some are more like essays, and many contain interesting new ideas, to which readers are requested to react in subse- quent volumes. Many contributions are by younger scientists. The majority of the authors 211 are from North America and the United Kingdom but there are contributions trom Western Europe and South America as well. The books are produced in small but readable typescript-offset. The photographic illu- strations are well reproduced. Textbooks 38 E. BLECHSCHMIDT. 1976. WIE BEGINNT DAS MENSCHLICHE LEBEN Christiana-Verlag, Stein am Rhein. 168 pp., 63 figs. This is an entirely rewritten version of the author's earlier book Vom Ei zum Embryo (1968). It is based on unorthodox ideas which are by now well known, particularly in the German-speaking world: kinetic anatomy, developmental dynamics, formative movements (Gestaltungsbewegungen) , and "metaboUc fields" (Stoffwechselfelder). The latter two concepts are derived from a painstaking morphological analysis of human development, the results of which have already been laid down in a number of more extensive works for the specialist. The present book is an outline that is apparently meant primarily for the general reader. The book is illustrated with excellent line drawings and photographs, for the most part taken from the author's earUer works. It is concluded by tabular surveys of human devel- opment and a glossary. 39. G. MICHEL. 1977. KOMPENDIUM DER EMBRYOLOGIE DER HAUSTIERE. 2nd edit.

The text is some 25 pages longer, three of which are taken up by a new chapter on teratology. A few new illustrations were added and the list of additional reading was somewhat extended. 40. G. H.

The book has remained essentially the same but expansion in several places has led to an increase in length of 30 pages. A short chapter on the development of the sense organs of the head was added. Several new figures were inserted and several others replaced. The chapter bibliographies were extended. Monographs 41. R. W. BEARD and P. W. NATHANIELSZ, eds. 1976.

However, it can be of value as a work of refer- ence to mammalian and human embryologists. Of the 37 contributors 29 are British or Commonwealth. The 26 chapters are compendious reviews with long reference lists and together provide almost complete coverage of our knowledge of human and mammalian 212 fetal life as the product of physiological and clinical research. Most of them are up to date until 1974 or '75. The book is well produced. It is illustrated almost entirely with graphs and diagrams. The large majority of the literature cited is in English. 42. I.

The significance of the published proceedings will be obvious to all those working or planning to work with primates. There are 30-odd papers interspersed with discussions. Rather than enumerating all the contributions we want to single out some topics that are of specific importance to embryologists working with primate material: comparison of embryonic and foetal development of man and rhesus monkey (29 pp. including dis- cussion); chronology of development of embryo and placenta in Tupaia (3 pp.); deter- mination of early pregnancy and stage of foetal development inMacaca (16 pp.); macaque and marmoset as animal models for birth defects (1 1 pp.); comparison of developmental stages in primates (12 pp.); and possibilities oixxsmgMacaca arctoidesmt&xditolo^y {^ pp.).

The book is clearly of most immediate importance to obstetricians but some contributions may be of interest to mammalian embryologists. Most papers are reviews of greatly varying length; two are research reports. The 15 contributions are grouped as follows (we briefly indicate the subjects of more general importance in parentheses); Techniques (2 papers); Growth in size and its postna- tal implications (6, of which one on metrical growth and skeletal development and one on vulnerable periods in brain and somatic growth); Growth in function (4, among which endocrine function, biochemical development, immune competence); Factors affecting growth (3, of which one on non-specific esterases).

In so far as developmental biology deals with phenomena occurring during the life cycle, it is natural to place it in the broad context of reproduction. In this book the author, who is both an embryologist and a reproductive biologist, does this on the whole in an admir- able manner. The book paints a very wide panorama indeed, and would be very suitable to make students of development aware of the place of their science in the whole of bio- logy (in the non-reductionist sense). That the book arose out of lectures is apparent from its easy style. It is full of unortho- dox ideas, often amusing, and occasionally provocative (especially in the sections dealing with social and cultural patterns.) The amount of embryology in the modern sense is natu- rally restricted and the chapters in question are slightly marred by some mistakes and inaccuracies. Particularly useful and informative are the chapters on larval forms, viviparity, life cycles and evolution. The illustrations, both line drawings and photographs, are all original and on the whole very good. There is a good glossary. The 15-page reference list serves as an author index. The index is extensive (but does not include "induction"). Monographs 47. A. E. BEER and R.E. DILLINGHAM. 1976. THE IMMUNOBIOLOGY OF MAMMALIAN REPRODUCTION Prentice-Hall, Englewood Cliffs.

It is a concise synthesis of the basic observations and principles in this field and is well suited for rapid orientation. Due to the limited documentation it is not suitable as a reference work. The book is easy to read and the treatment is critical, as we may expect from such eminent authorities. In a series of 15 chapters of convenient length virtually all aspects pass in review. Eight chapters deal in one way or another with the period of gestation, 214 and one (briefly) with the ontogeny of immune responses. Each chapter has a selective reference list of one to a few dozen titles. The book is adequately produced. All illustrations are original and serve their purpose well. 48. R. B. L. GWATKIN. 1977.

In this book the eminently qualified author reviews the new knowledge in a concise but well- documented form, paying attention to morphological, physiological and molecular aspects. Recent data on amphibian and invertebrate (mainly sea urchin) gametes have been inclu- ded wherever appropriate. The book consists of 15 brief chapters. Fertilisation is defined broadly: there are chap- ters on the egg and the sperm, on gamete transport, on sperm capacitation, and on part- henogenesis. Other subjects are the prevention of polyspermy and pronucleus formation. An epilogue lists some two dozen questions which should be attacked in the near future. The book is well produced and illustrated with good line drawings, photographs and electron micrographs. The 34-page bibUography is up to date until well into 1976. 49. E. C. ROOSEN-RUNGE. 1977. THE PROCESS OF SPERMATOGENESIS IN ANIMALS Cambridge Univ. Press, Cambridge, etc. Developmental and Cell Biology Series, vol. 5. VIII, 214 pp., 38 figs., 14 pis., 12 tabs., author, taxonomic and subject indexes. £ 15.50 This scholarly monograph is comparative in character and emphasises spermatogenesis as the development of a peculiar population of cells set apart in the metazoan body, an organismic process in some ways similar to early embryogenesis. It follows that much attention is devoted to the relationships between germ cells and somatic cells. Differen- tiation and endocrine and genetic control are treated as supplementary subjects. Much older work that is in need of re-investigation is cited. After an interesting historical survey the treatment is at first strictly systematic, starting with the Porifera and ending with the vertebrates (with comparatively little space devoted to mammals). Next there are brief chapters dealing in a general manner with the kinetics of spermatogenesis; degeneration, polymorphism and genetic control; and compartments and auxiliary cells. Much useful information is presented in tabular form. The book has a glossary that is meant as a contribution to the conscious use of terms. The bibliography covers 31 pages of small print. In the text there are numerous good line drawings reproduced from various (often older) sources. These are supplemented by 14 plates of good quaUty , several of which are again beautiful old drawings. 50. J. S. SCOTT and W. R. JONES, eds. 1976.

The chapters of most immediate interest to mammalian embryologists are those by Johnson (Fertilisation and implantation, 28 pp.), Mendenhall (The immunology of the fetal-maternal relationship, 20 pp.), Billington (The immunology of trophoblast, 22 pp.), Jones (Fetal and neonatal immunology, 42 pp.), and Scott (Immunological aspects of trophoblastic neoplasia, 20 pp.). Several other chapters maybe of interest to teratologists. The volume is well produced and adequately illustrated. 215 Symposium reports 51. M. EDIDIN and M. H. JOHNSON, eds. 1977.

Of the 1 1 papers pres- ented 10 were by American authors. Most of the contributions are concentrated reviews of recent research and all are followed by extensive and interesting group discussions, complete with references. The first seven papers all deal in one way or another with the membranes, surface anti- gens and enzymes of mammalian spermatozoa. The last four are of wider interest to embryologists. Two of these are somewhat outside the scope of the volume (one by Van Blerkom on electrophoresis of rabbit oocyte and embryonic proteins, and one by Epel on fertilisation in sea urchins). The other two are by Solter (organisation and antigenic prop- erties of mammalian egg membrane) and by Yanagimachi (sperm egg interaction in mammals). The volume is very well produced and illustrated. IMPLANTATION, PLACENTA, FETAL MEMBRANES AND FLUIDS (see also 3,37, 47, 50,86,101) Dissertations 52. R. BAUR. 1977.

C. in June 1972 and the papers for the book were prepared soon after that. The time-lag until publication is bridged by the last Daper, which is up to date until the middle of 1975 and has over 180 references. The table of contents speaks for itself. All papers are authoritative reviews with varying emphasis on the authors' own research. Nearly all are of great interest to mammalian 216 embryologists. Several contain very useful surveys of relevant data in tabular form. The book is attractively produced and illustrated mainly with photo- and electron micrographs.

VIII, 334 pp., 531 figs., subject index. $ 65.00, Y 16,000,Dfl. 160.00 This book, written by four Japanese authors, is mainly meant for clinicians as a guide to the supporting embryological evidence for congenital malformations. Some of the material, as well as the bibliography, may be of use to human embryologists. The book is based mainly on an autopsy population of some 6000 embryos (induced abortions) collected in Kyoto and some 6000 fetuses (mainly induced and spontaneous abortions) collected in Hiroshima. The bulk of the book consists of some 785 photographs and photomicrographs of mostly good quality, provided with descriptive captions. Most of these are of fuU-term fetuses or neonates, but there are a fair number of earUer stages among them. They are supplemented by brief texts considering, among other things, the pathogenesis and etio- logy (if known) of the malformations. The texts often have explanatory line drawings. In some of these the lettering, pointers and captions are somewhat inadequate. The mal- formations are arranged mainly according to organ systems. The bibliography covers 29 pages of small print and consists of literature cited in the text plus selected titles form the world literature. There are five pages of selected litera- ture on normal human development, arranged by organ system. The book is well produced on glossy paper. Monographs 55. C. L. BERRY, ed. 1976.

It contains 15 brief reviews, with fairly long to long reference lists, on variety of subjects. About half of these could be of interest to those working in experimental teratology out- side the clinic. We specifically mention the papers by Berry and Barlow on reproductive toxicity tes- ting, by Beck on model systems in teratology, by Poswillo on mechanisms and pathoge- nesis of malformation, and by Wolpert on mechanisms of limb development and malform- ation. 217 Dissertations 56.

The title is a little mis- leading: only about a third of the 27 papers have a direct bearing on the area indicated by the title, and some even seem entirely out of place. On the other hand, many authors make an effort to point out the possible teratogenic implications of their findings on basic aspects of normal development as studied in vertebrate cells, tissues and organs in vitro. A great variety of such systems pass in review, usually by estabUshed authorities from many countries. Many contributions are extremely interesting but there is little unity in the volume as a whole. The contributions vary greatly in length and format. Most are brief to medium-length reviews of recent work, often unpublished at the time of writing. There has been minimal editing and the conference discussions are not recorded. The book is well produced and profusely illustrated; the numerous photographic illus- trations are well reproduced. The book has no indexes. 218 Reference works 60. L. WEINSTEIN, ed. 1976. TERATOLOGY AND CONGENITAL MALFORMATIONS, a comprehensive guide to the literature, 3 vols. Plenum, New York, etc. vol. 1 Bibliograpny: 464 pp.; vol. 2 KWIC Index part one: 570 pp.; vol. 3 KWIC Index part two and author index: 538 pp. $ 234.80 the set This most useful set of volumes is best characterised by reprinting the entire second paragraph from the Preface: The material of this book ranges from experimental to clinical, with the emphasis on the former. A majority of the references concern malformations, especially those in- duced by chemicals, drugs, pesticides, diseases, stress, environment, etc. Techniques and methods for the study of teratogenesis is another weU-represented category. Each reference in this group has had the words "test method" added to the title to assist in locating such papers in the KWIC index. Also included are those aspects of embryo- logy, reproduction, and genetics that lead to a better understanding of the development of the malformations. In recent years, references to mutagenicity and screening tests for carcinogenicity have been added. An effort has been made to include books, book reviews, symposia, conference proceedings, and abstracts from meetings. The work is a compilation of aU references contained in a current awareness bulletin produced by Lederle Laboratories since 1963, plus the references from several retrospec- tive searches going back to around 1950. The total number of references Usted is more than 13,000, the last 2,000 of which date from 1974. The listings are in the form of a Bibliography (vol.1) and a computer-produced Key Word In Context index (vols. 2 and 3) referring back to the Bibliography. The KWIC index is based on the titles plus appropriate keywords supplementing them. Titles in 24 languages other than English have been trans- lated into EngUsh. The author index at the end of vol. 3 of course also refers back to the BibUography. The volumes are sturdily bound. It is to be hoped that the volumes will be updated from time to time.

DM 96.00, $ 39.40 The preparation of this volume was prompted by the desire to meet some urgent funda- mental needs of developmental pathology. Indeed, some rather recent avenues are ex- plored in it, and it ought to be of great interest not only to pathologists but to all mam- malian embryologists. Most of the 19 contributors are established authorities in the field; all but two are from Western Europe. The 12 contributions are well-organised reviews ranging in length from half a dozen to two dozen pages. (Not all of them are equally up to date and only one has been updated.) After a brief introduction by Austin the contributions are arranged in four sections as foUows: Oocyte, early embryo and maternal host; morphology and biochemistry (4 papers), Pharmacological and hormonal influences in early embryogenesis (3), Teratology (2), and Cytogenetics (3). We cannot list aU individual contributions but want to make an excep- tion for the paper by Denker, in which he reviews the problem of early determination on a comparative basis and concludes that it is too early to decide between the "inside-out" and the cytoplasmic localisation hypotheses, and that both may be true. The volume is well pnnted and superbly illustrated. 219 Symposium reports 62. J. H. COGGIN, Jr. and N. G. ANDERSON, eds. 1976.

It was concerned with the relationships between cancer and normal development, particularly their bio- chemical and genetic aspects. The reviews and research reports of most general scope, and therefore of greatest inte- rest to mammaUan and other embryologists, are those in the first two sessions (4 papers each): Molecular basis for programming in development, and Embryonic and fetal devel- opment. The remaining sessions deal with Relationships between shared tumor and fetal products. Antigenic determinants of colonic cancers, and Tumor antigens and embryonic antigens on neoplasms. The volume is well illustrated. 63. W. H. FISHMAN and S. SELL, eds. 1976. REGULATION OF GENE EXPRESSION IN DEVELOPMENT AND NEOPLASIA Amer. Assoc, for Cancer Res., Bethesda. Cancer Research, vol. 36, 11, pt. 2., 131 pp., 106 figs., 25 tabs. The borderland between cancer and normal development is becoming a more and more important area. The present symposium, held at Santa Ynez, CaUf. in July 1976, was devoted to this area. The participants were predominantly American (with two from Paris and two from Japan). Of the 19 contributions four are reviews while two are theoretical in nature. The papers of most direct interest to our readers are in part one: Model systems for the study of oncodevelopmental gene expression; this is in two sections, one dealing with murine teratocarcinoma (5 papers) and one with neoplastic transformation (6 papers). The so-called oncodevelopmental gene products appear again and again in the discussions. The eight papers in part two deal with Molecular mechanisms of gene regulation. Among them is a new model for the control of transcription during development involving small RNA chains. The issue is profusely illustrated. REGENERATION, RENEWAL Textbooks 64. P. MATTSON. 1976. REGENERATION Bobbs-Merrill, Indianapolis. XIV, 178 pp., 52 figs., subject index. $ 4.95 (paper) This little book was written for the educated layman. It is therefore highly selective, avoids some of the more abstruse problems such as modulation/dedifferentiation and pat- tern formation, and places much emphasis on the possible applications of regeneration results in medicine. Nevertheless, the treatment is scientifically rigorous. The author writes interestingly and avoids jargon. The book is restricted almost entirely to present-day regeneration research in the U. S. A., apart from a useful chapter on Russian work. Another feature is a special chapter on regeneration in plants. The book is well illustrated. It has a list of Scientific American articles and extensively annotated book titles. 220 65. L. V. POLEZHAEV. 1977. REGENERATION (in Russian) Znanie, Moscow. Novoe v Zhizni, Nauke Tekhnike, Ser.

One of its major aims was to bring together investigators from many disciplines to exchange information on stem cells under normal steady state conditions as well as during development, ageing, regeneration and neoplasia. Of the 38 participants, 27 were from North America, 10 from Great Britain, and one from France. Most of the 26 contributions are surveys of recent original work mixed with varying amounts of review material. The contributions are arranged in six sessions as follows (abridged): Intestine (6 papers). Epidermis (3), Hemopoietic and lymphoid tissue (4+5), Testis (4), and Growth, ageing and neoplasia (4, of which one on teratocarcinoma). Each session is concluded by an in- formative digest of the discussions held. L. F. Lamerton has provided thoughtful opening and concluding addresses. The volume is dedicated to C. P. Leblond. The book is produced in good offset print and very well illustrated. Collections of papers 68. N. M. GORELIK, ed. 1976. PROLIFERATIVE PROCESSES AND REGENERATION (in Russian) Publ.

Embryol. Inf. Serv. 15. 2, 1975. The present book is divided into four sections and an epilogue by the editor. Section 1 is entitled Historical and theoretical aspects and has two chapters. In a brief introduction the editor points out that the nativism - empiricism controversy, reformu- lated as a developmental problem, plays a role in all the chapters of the book. Section 2, entitled Neurospecificity: Chemoaffinity theory, has chapters by Keating and by Meyer and Sperry, in which the problems of visual neuronal connectivity in lower vertebrates and mammals are reviewed from slightly differing perspectives. This section is of greatest interest to embryologists. Sections 3 and 4 are called Neurospecificity: Exper- ience, and Behavioral specificity and have two chapters each. They deal with visual and auditory perception in developing birds and mammals. Textbooks 71. H. E. SCHROEDER. 1976.

DM 24.80 (paper) This text for dental students is written from a modern point of view, in which develop- ment, cell differentiation, cell biology and structure form an integrated whole. It could therefore be of interest to those biologists who are starting work on tooth development and related subjects. Special features of the book are its numerous excellent line drawings (many with colour) and the chapter bibliographies consisting of carefully selected older and recent references from the world literature. 222 72. N. K. WESSELLS. 1977. TISSUE INTERACTIONS AND DEVELOPMENT Benjamin, Menlo Park, Calif., etc. X, 276 pp., 135 figs., subject index. $ 10.00 (paper) Although this book was written for undergraduate students it is so full of ideas that it makes delightful reading for any "mature" developmental biologist. Its illustrations, parti- cularly the many scanning electron micrographs, are a joy to behold. The advantage of a book such as this is that it can delve much more deeply into the subject than is possible in a comprehensive text. If this is moreover done in such an authori- tative and thoroughly modem, yet critical and balanced manner, the result is most enjoy- able. The treatment is of course selective but the examples are well chosen and the whole text is well integrated. Whether we move at the level of the organ, the tissue, the cell or the cell surface the sense of unity is never lost. The term "tissue interactions" is taken very broadly and encompasses the role of hormones, nerves, extracellular materials and cell coupling. Other good features are the summary "concepts" (or rather "conclusions") at the end of each chapter and the annotated lists of readings. It is rather odd that no magnifications are provided for the electron micrographs. In fig. 14.5 two pictures are transposed and there are a number of annoying printing errors. Monographs 73. T.

Malnutrition and mental development The table of contents of this monograph speaks for itself. The author has "tried to select the most important animal and human studies, to evaluate them, and to develop an 223 overall picture of the consequences of early malnutrition . . .[for] brain structure and function". Because the present reviewer is not an expert, he feels he ought to say that not all competent reviewers have been equally enthusiastic about the book. It is something be- tween an exhaustive review and a basic account, and should perhaps be contrasted with the equally recent but much longer book by Ph. R. Dodge and others on the same subject. The book is attractively produced and has many clear graphs and diagrams. 76. D. WUNSCH. 1975.

The volume contains 20-odd medium-length reviews of recent research, mostly that of the contributors themselves. All of them are in English and all are followed by usually brief discussions. About half of them are of predominantly clinical interest. The first ten reviews will be read with interest by all those working on limbs or on organogenesis generally. Among the aspects dealt with are developmental anatomy, histo- chemistry, collagen biochemistry, and various teratogenetic and genetical approaches, all of this in man and various mammals (occasionally chick) and with reference to different developmental periods.

Of the ten short to medium-length, up-to-date reviews two are of exclusively clinical interest, the others are of interest to mammalian and human embryologists and teratologists. The subjects covered range from sex determination and differentiation in germ cells, through morphogenesis of various parts of the human genital system, to various endo- crinological aspects. No discussions are recorded. The book is well produced and illustrated; most of the photographs and light micro- graphs are well reproduced. 225 83 M. LIEBERMAN and T. SANO, eds. 1976.

The 48 contributors are from many different countries, the majority from Japan and the United States. The contribu- tions are for the most part brief research reports or surveys of recent research. Most focus on the application of relatively new techniques to embryonic heart muscle cells of birds and mammals, and aU but a few are of interest to developmental biologists. The 20 contributions deal successively with electron microscopy of heart cells in vivo and in vitro, with several aspects of membrane permeability and electrophysiology of heart cells, and with physiological correlates of heart muscle. Each contribution is followed by a carefully edited summary of the group discussion succeeding it. The book is luxuriously produced and profusely illustrated. The photomicrographs and electron micrographs are of high quality. 84. , , A. RAYNAUD, organiser. 1975. TEMPERATURE ET ORGANOGENESE; Table ronde organisee par la Societe Zoologique de France Soc.

Fr. 190.00 (paper) "Rudimentation" is a newly coined French word which is unfortunately ambiguous in EngUsh. It refers, not to "rudiments" as used in English, but to rudimentary organs and their origin. This symposium was held in Toulouse m September 1976 and was attended by specialists mainly from France, the United Kingdom and other West-European coun- tries. Most contributions are brief reviews or summaries of recent work. They are either in French or in English and most have a summary in the other language. Most are followed by a brief group discussion. Of the 33 main contributions more than two thirds are of interest to embryologists. Ten of these deal with limb development, the others with a variety of other organs in many different vertebrates. Eight papers deal with developmental inhibition due to hor- monal factors, nine with disturbances of morphogenetic mechanisms, and three with chemically induced limb abnormalities. A concluding general discussion has a section on the term "rudimentation" and two contributions on phylogenetic aspects of chick limb development. The volume is well produced and illustrated with good line drawings, photographs and light and electron micrographs. 226 CELLULAR DEVELOPMENTAL BIOLOGY(incl. ceU culture, cytochemistry) (see also 25,59,72,83) Treatises 86.

All of the 13 extensive reviews are authoritative, comprehensive, well organised, and interestingly written. A good balance is struck between events at the tissue and cell level and those at lower levels of organisation. In works such as this it is always possible to disagree with the choice of subjects. I personally feel the chapter on inductive tissue interactions is a bit too long, and I regret that no attention is devoted to neuronal specificity and to work on insect imaginal discs. The chapter on positional information is stimulating but, perhaps inevitably, very specu- lative in places. The chapter bibliographies are extensive and up to date until 1975. The book is superbly produced and illustrated. Textbooks 87. N. MACLEAN. 1977. THE DIFFERENTIATION OF CELLS Arnold, London. Genetics - Principles and Perspectives: a series of texts, vol. 1. VIII, 216 pp.', 96 figs., 14 tabs., subject index. £ 12.00 (cloth), £ 5.95 (paper) This book was written for advanced undergraduate and graduate students of genetics and cell biology. It is on the whole a successful, well-balanced synthesis from the view- point of cell biology; the presentation of embryological data is not always correct. The style is stimulating and the conclusions are carefully formulated. The subject is developed logically on the basis of evidence from a broad variety of organisms, starting with the Protozoa. Equal attention is devoted to the genome and the cytoplasm. There are separate chapters or sections on the role of hormones, on the cell surface and cell con- tact, on episomes, viruses and abnormal genetic elements, and on cancer and differentia- tion. The illustrations on the whole serve their purpose weU, but some do not match the text entirely, or the legends are not extensive enough to bring complete understanding. The 15-page bibliography is of course selective but very useful. The books shows signs of inadequate proofreading. 227 Monographs S. H. BARONDES, ed. 1976.

Ever since the days of Harrison, Detwiler and Weiss the ner- vous system has been a paradigm for other developing systems. This book, by a team of predominantly American authors, expertly reviews the "state of the art" of the cellular and molecular aspects of neurogenesis. The chapters of greatest interest to our readers are to be found in section I (Specificity in synaptic development and regeneration) and section III (Toward a molecular basis of neuronal recognition). We just mention some of the authors: Jacobson, Fambrough, Bunge in section I; Moscona, Roth, Toole, Barondes in section III. The contribution by Barondes and Rosen has the added interest of drawing a parallel between findings in cellular slime moulds and the nervous system. 89. G. BUTSCHAK. 1976.

M 39.00 (paper) This monograph is a thorough, very comprehensive and critical review of the bio- chemical basis of cell division and cell differentiation. The more is the pity that it has taken so long to produce. It reflects the state of the field in the beginning of 1973, but so much has happened since that in many areas the author would have placed a different emphasis today. Nevertheless, for the literature prior to about 1973 it is a valuable reference work. The book is in three weU-organised main parts: Biochemistry of cell division. Bio- chemistry of cell differentiation, and Regulation of cell division and cell differentiation in tumour cells. There are 12 subsections in all, which all have concise but clear summaries. The book is produced in small offset print and is sparsely illustrated. The references number more than 850 in all. 90. T. P. EVGENEVA. 1976.

The NATO Advanced Study Institute in question was held in Bellagio in September 1975. Sixof the 32 research reports deal with D/crvo^reZ/wm, particularly with cell-surface lectins and cyclic AMP receptors (one deals with a macro- molecular effector of cell differentiation). The authors are Barondes and Rosen and their group, Gerisch, Malchow et al, Town, and Darmon et al. Other papers deal with sponge cell aggregation (Burger's group), adhesion of neurons (Gottlieb's group), and membrane components in differentiating muscle cells (Prives). 93. N.

Among the contributors were established authorities but also many younger people. Like the report of the first conference in this series the book is heterogeneous but provides a useful cross section of the many different approaches and systems being used at present. Most of the contributions are short research reports or reviews of recent work. The 58 contributions are grouped into six sections as follows: Cell proliferation, growth and expression of differentiation potential by proliferating cells (9 papers); Regul- ation of gene activity and chromatin activity during cell differentiation (11); Cell mem- branes and ceU surfaces in relation to differentiation (4); Aspects of carcinogenic dis- orders and differentiation (15); Hormonal induction of cell differentiation (7); Normal and malignant hemopoiesis as a model of differentiation (12). No group discussions are recorded. The book is produced from typescripts in good offset print and profusely illustrated; the numerous photographs are well reproduced. The subject index is curiously deficient. DEVELOPMENTAL BIOCHEMISTRY, MOLECULAR BIOLOGY (see also 13,16,25,62 , 63,89,91,93) Textbooks 94. E. H. DAVIDSON. 1976. GENE ACTIVITY IN EARLY DEVELOPMENT. 2nd edit. Academic Press, New York, etc. XVI, 452 pp., 87 figs., 16 tabs., combined subject and species index. $ 18.50, £ 13.15 Contents: 1. Introduction: the variable gene activity theory of cell differentiation; 2. The onset of genome control in embryogenesis; 3. First indices of differential embryo 229 cell function; 4. Quantitative aspects of protein synthesis in early embryos: the role of maternal components; 5. Transcription in early embryos; 6. RNA sequence complexity and structural gene transcription in early embryos; 7. Localization of morphogenetic determinants in egg cytoplasm; 8. Lampbrush chromosomes and the synthesis of hetero- geneous nuclear and messenger RNA's during oogenesis An indication of the enormous growth of the area covered by this book is the length of the bibliography, which has almost doubled since the first edition even though part of the original references have been deleted. The contents of the book have been consider- ably rearranged and the book is in fact almost a new one. We must be grateful to the author for undertaking this arduous task with such excellent results and without unduly increasing the size. That the treatment is basically organised around his personal views and interpretations is understandable and increases rather than decreases the book's value. As in the first edition, the basic tenet is that regulation at the transcriptional level is the fundamental process underlying differentiation and development. This, and the em- phasis on early stages, is probably the reason why a class of problems which are considered fundamental by many embryologists, i.e. induction, determination and competence, receive little or no attention as subjects in their own right. One hopes that these pro- blems, though elusive at present, will also capture the attention of molecular embryo- logists in the years to come. Apart from numerous extensions of the original material, the major new features are ch.4 and the first section of ch.6, which deals with nucleic acid sequence complexity and the kinetics of renaturation and hybridisation. The book is attractively produced and illustrated. The 48-page bibliography is remark- ably up to date. (An oddity is that Crawford and Wilde's 1973 experiments with pacta- mycin in Fundulus are not included.) The absence of an author index is to be regretted; it would have been easy to use the bibliography for that purpose. Monographs 95. N.MACLEAN. 1976. CONTROL OF GENE EXPRESSION Academic Press, London, etc. XII, 348 pp., 21 figs., 6 tabs., author and subject index- es. £ 7.80, $ 19.25 Contents: 1. The control of gene expression and its levels of action; 2. Gene expression in prokaryotes; 3. Experimental systems of differential gene function in eukaryotes - systems involving one type of protein; 4. Experimental systems of differential gene functions in eukaryotes - systems of limited complexity; 5. Experimental system of differential gene functions in eukaryotes - systems not well understood in molecular terms; 6. RNA involvement in gene expression; 7. General concepts of gene regulation The level of treatment in this well-written book is between that of an introduction and that of a specialised monograph. For the student making up his mind on what research to embark on it is a stimulating guide. The main function it may perform for the specialist is to make him more aware of the advances in and the potential of systems other than that on which he happens to be working. The main substance of the book is to be found in chapters 3-5. In ch.3 "system" means a particular type of protein; eight such proteins are discussed, ranging from immunoglo- bulins to vertebrate egg proteins and including two insect proteins. In chs. 4 and 5 "system" usually means a tissue, organ or organism, occasionally an approach or a class of proteins. Many phyla, both plant and animal, are represented. The bibHography, though selective, covers 34 pages and is up to date until 1974. The book is attractively produced and illustrated. 230 Dissertations 96. J. HAKKARAINEN. 1975.

Yet we may safely say that it will long remain a firm foundation to build on for those who are entering the field, as well as a great help for all mammalian embryologists. The subject matter is subdivided into 1 1 short, readable chapters. Two of these deal primarily with experimental-embryological aspects, five with developmental genetics. The last of these is entitled Chimaeras versus mosaics. A separate chapter thoughtfully and critically discusses the distribution of cell populations in the embryo, in other words, the problem of "clones and patches". The book is beautifully produced and well illustrated. The 14-page bibliography ends in 1974, with the exception of the pubUcations of the author and her associates. Three important papers published in 1975 have been added in proof. The subject index could have been longer; particularly unfortunate is the omission of "determination" and "allo- cation". 98. R.

VIII, 534 pp., 155 figs., taxonomic, author and subject indexes. £ 16.00, $ 35.00 The author of this exhaustive monograph has previously written two similar, though shorter works, one on the insect head (1965) and one on the thorax (1970). In the pre- sent work, however, more stress is placed on developmental aspects. Part I, which occupies 48 pages and discusses these aspects in a general way, is not restricted to the abdomen nor indeed to insects. It deals with various aspects of heterochrony and with substitution, homology and analogy of organs on the basis of the modern literature. It is odd that heteromorphosis or homeosis, for which some recent authors have suggested important roles in evolution, is not even mentioned in passing. Part II (60 pp.) ueals mamiy wim general aspects of abdominal segmentation, abdo- minal appendages, and external and internal genitalia. Finally, Part III covers the available data in the individual orders. In most orders some attention is devoted to *he origin of the 231 germ cells. The musculature is not treated because the author is convinced that it is not important in establishing homologies. The book is well produced and illustrated with numerous good line drawings. It has a bibliography of 7 1 pages. Reference works 99. R. RIEGER, A. MICHAELIS and M. M. GREEN. 1976. GLOSSARY OF GENETICS AND CYTOGENETICS, classical and molecular. 4th completely revised edit.

The tremendous development of the field since 1968 is reflected in a size increase of some 150 pages. About half of the text has been completely rewritten. One seldom turns to the book in vain. After spending an hour with it the only serious omissions this embryologist (!) could find were "germinal granules" and "sturt".

The reason why we review it here is that it contains several sections which could be useful to students and others interested in developmental immunology. Part One deals with the fundamentals of the immune reaction and its technical, bio- chemical and cellular aspects. Part Two treats the immune reaction in the living organism. It contains brief accounts of the development of immune competence and of the immune system (including cellular differentiation). Part Three, entitled The immune reaction in the laboratory, has a final section on the application of immunological techniques to the problem of cellular differentiation. Although authors' names are frequently used in the text, the bibliography is restricted to nine recent books and articles. The book is illustrated with good line drawings and dia- grams and has a useful glossary. Monographs 101. B. L. MIRKIN, ed. 1976. PERINATAL PHARMACOLOGY AND THERAPEUTICS Academic Press, New York, etc. XII, 455 pp., 38 figs., 31 tabs., subject index. $ 24.50 Contents: 1. Placental transfer of pharmacologically active molecules (Mirkin and Singh); 2. Drug biotransformation reactions in the placenta (Juchau); 3. Disposition of drugs in the fetus (Waddell and Marlowe); 4. Pharmacologically induced modifications of behavioral and neurochemical development (Thorburg and Moore); 5. Chnical im- plications of perinatal pharmacology (Yaffe and Stern) This book was written by an all-American team of experts. It consists of five well-or- ganised reviews which discuss critically and in depth the main areas that are currently under active investigation in this field. Areas where the amount of data was considered in- 232 sufficient to allow of substantive conclusions were omitted. The table of contents above speaks for itself. Ch. 5 has a 6-page section on teratogenic effects of drugs. The chapter bibliographies run up to 1972/73, with occasional updatings. They reflect the rather strong bias towards literature pubUshed in EngUsh which is com- mon in books by Anglo-Saxon authors. The book is well produced and adequately illustrated. 102. P. W.

Dfl. 75.00, $ 30.75 This monograph is a thorough and critical review of fetal endocrinology against the background of sequential data obtained from the chronically catheterised sheep fetus. The author carefully evaluates the similarities and differences between the sheep and other experimental mammals and man, and devotes much attention to the criteria of physiolo- gical normality during experiments. After a general introduction and a chapter on methodology the subject matter is treated partly by organ systems (testis, hypothalamo-hypophysial-portal system, thyroid - two chapters of which one on ruminants -and neurohypophysis), and partly by hormones. A final chapter deals with parturition and the feto-placental unit. An appendix lists methods for the calculation of the production rate of fetal hormones. The endocrinology of carbohydrate and intermediary metaboUsm will be dealt with in a subsequent volume of the series. The book is luxuriously produced; it is illustrated mainly with graphs and line dra- wings. The bibliography numbers over 600 titles; I do not know whether this reflects the actual state of things, but it is striking that it contains almost no non-English titles. Dissertations 103. X.

The majority of the participants were from various European countries (with France predomi- nating), but a dozen came from North America. The stress lay on the biosynthesis, meta- bolism and cellular action of invertebrate hormones. Of the 50 contributions at least ten may be of interest to developmental biologists. These deal with hydroids, planarians, annelids (3), molluscs, and insects (5). Three deal specifically with oogenesis in Perinereis and Octopus. The papers are in French or English but all have summaries in both languages. The volume is illustrated with line drawings. 233 105. L. I. GILBERT, ed. 1976.

Effects of juvenile hormone at the molecular level (protein synthesis) This symposium was held in Lake Geneva, Wis. in November 1975. Although it is evi- dently of major significance to insect endocrmologists, at least one third of it is of impor- tance to developmental biologists. The participants came mainly from North America and Western Europe. Most of the contributions are medium-length research reports; some contain considerable review material; much of the material was unpublished at the time of the symposium. Each of the five parts listed above is preceded by a most useful and inter- esting summary of about half a dozen pages. Almost all of the eight papers in Part III are of direct interest to workers in insect morphogenesis. Most focus on the interaction between JH and ecdysone. Among the con- tributors we mention the following: Krishna Kumaran, Riddiford, Oberlander, Masner, Lezzi, Willis, and Sehnal. A paper by Fristrom et al. in Part V deals with Drosophila imaginal discs. The book is produced in good offset print and adequately illustrated. 106. M. LiJSCHER, ed. 1976.

This symposium, which was held in Washington DC some time during 1976, was devoted to this notion. Most of the contributors came from Western Europe (one each from Australia and Canada). The introductory paper was con- tributed by Liischer. Nine of the ten main contributions are reviews in English of recent work on various bees, ants, termites and aphids. The paper by Hrdy is only an abstract. In the interest of rapid publication the papers were reproduced direct from the type- scripts and no attempt was made to reduce overlap. The book is adequately illustrated; it has no indexes. METHODS (no entries, but see 58,96,102) HISTORY, BIOGRAPHIES, etc. Monographs 107. D. J. HARAWAY. 1976.

Press, New Haven, etc. X, 23 1 pp. , combined subject and name index. $ 1 5 .00 The argument in this book hinges strongly on Thomas Kuhn's controversial ideas con- cerning the evolution of science. The author regards the twentieth-century switch from mechanicism to organicism as a paradigm change in the Kuhnian sense. This aspect of the 234 book will appeal most to the professional historian and philosopher of science. However, quite apart from such issues the bulk of the book will be of great value to those embryologists who are interested in the origin of the ideas and concepts they are using, and generally to all biologists who want to be conscious of the more philosophical context of their often automatic or traditional ways of thinking. And it cannot be denied that a concept such as morphogenetic field, though pronounced meaningless by some, is still considered useful and even indispensable by many others. The part of the book to which I am referring consists of chapters 2-5. Ch.2 is a thoughtful brief essay on the origins and elements of organicism. The other three chapters lucidly review the intellectual development of three great men of the era in question: Ross G. Harrison, Joseph Needham, and Paul Weiss. These make delightful reading for anyone even remotely interested. The book is attractively produced but is disfigured by rather many printing errors. It has no illustrations. The most recent references (e.g. Thom, Wolpert) do not include the definitive published works of these authors. The long index conforms to scholarly stan- dards.
