Europe . Ill Subject Index (alphabetical order) 132 International Organizations and Facilities 184 Book Notices 189 INTRODUCTION Since 1973 each volume of General Embryological Information Service is issued in two parts: Part 1 contains the data on research workers in Europe. 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 organized 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 RothschUd, 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 Mammalia, Reptilia, Amphibia, and Insecta it is the order, while in Crustacea and Arachnida both the class and the order are listed. Due to the fact that the administrative seat of the International Society of Develop- mental Biologists is no longer at the Hubrecht Laboratory, membership of the Society is no longer indicated in the Directory of Names and Addresses. However, in the section on International Organizations we publish a complete ISDB membership list every other year (in part 1). A publication like this can only fulfil its role with the help of all developmental biologists. We therefore solicit your co-operation, particularly by alerting your colleagues to the existence of the Service, and by paying your subscription fees in time. This is indispensable for us to maintain a sound financial basis. J. Faber B. Z.

Scientists were asked to state theh name, degree(s), address, and research subjects in so far as recent, unpublished work in developmental biology was concerned.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. 1 5 were confirmed by the scientists still to be correct. Entries without research subjects a. Persons listed on the sheets as being engaged in research in developmental biology, without further specification of subjects. b. Persons with a complete entry in vol. 15 who have not returned their sheets. Name, degrees, and addresses were reprinted unchanged from vol. 1 5 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. 1 5 whose death has come to our attention (marked t)- Persons listed in vol. 15 but not in vol. 16 a. Persons who had research subjects in vol. 15 but are no longer engaged in research in developmental biology. b.

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 1975. Older information concerning such Institutes may be found in previous issues. EUROPE AUSTRIA Graz, Zool. Inst, der Univ. * FACHBACH, G. Salzburg, Univ. Salzburg, Bot. Inst.

Asst. 131 SUBJECT INDEX (alphabetic order) 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, Immunoche- mistry, Irradiation, Microcinematography, Rearing methods. Transfer (Blastpcyst, etc.), Transplantation, Ultraviolet Irradiation, Vital staining, X-Irradiation. Other techniques will be found as subheadings (see below). 5) General subjects: History, Theoretical biology. 6) Some groups of organisms: Plants, Unicellular organisms. Headings are extensively cross-referenced, but not usually from lower-order to higher- order categories. Subheadings Headings having less than ca. 10 names of investigators usually lack subheadings. The same research subject may be Usted 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 list appearing on the next page; some of these terms are also used as headings - the resulting redundancy 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 All the work on multicellular plants and on slime moulds is brought together under one heading: Plant embiyology & morphogenesis (experimental & physiological). All the work on unicellular organisms (including unicellular plants) is listed under the heading Unicellular organisms. 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, Plant embryology & morpho- genesis. Regeneration, Reproduction, Unicellular organisms, etc. Names of investigators In the case of work carried out jointly by two or more investigators, all collaborators are listed 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. 32 New Headings Pollutants Transfer (Blastocyst, etc.) Subheadings often used under various headings Techniques and disciplines Autoradiography Biochemistry (incl. biochemical techniques, molecular biology, etc.) see also: Enzymes, Tracer study Biophysics Culture in vitro Cytology Descriptive study* Endocrinology Enzymes Experimental study* Function General study* Genetics Histology Histo-& cytochemistry Immunology Irradiation Microcinematography Morphology Physiology Theoretical study Tracer study Transplantation Ultrastructure Processes Development* Differentiation Functional differentiation (maturation) Growth Induction Involution (regression) Malformations Metamorphosis Morphogenesis Necrosis (cell death) Organization (pattern formation) Pathology Regeneration Teratogenesis Stages Early development Fgg Embryo Fetus Larva Neonate Oocyte Oogenesis Placenta Postnatal Spermatogenesis These subheadings are also used when the available information was not detailed enough to use one of the more specific subheadings. 133 ABDOMINAL CAVITY see Body cavities ABNORMALITIES see Anomalies (early develop- ment); Malformations see also Teratogenesis ABORTIONS see Malformations; Pathology ACCESSORY SEX GLANDS see Reproductive system ACTIN see Muscle(s) ACTINOMYCIN see also Antibiotics Amphibia Ficq Van Gansen Aves Diethelm Hydrozoa Lui Znidaric Insecta Maisonhaute Truckenbrodt ACTIVATION see Fertilization ADAPTATION see also Environmental factors; Phylogenesis Amphibia Briegleb Aves Zusman Crustacea Juberthie Insecta Chauvin Delay Juberthie Reptilia Zusman Teieostei Durand Vertebrata Durand ADHESIVE GLAND see Gland(s) ADIPOSE TISSUE(S) zee also Lipid(s) Aves Dyer Insecta Labour Papillon Scheller ADRENAL GLAND see also Cortisol ne; Insulin; Steroids cortex Mammalia Mitskevidi culture in vitro Homo Bukulya Gyevai Mammalia Bukulya Gyevai enzymes Aves Accordi experimental study Mammalia Mitskevich function Amphibia Pehlemann Aves Hatier Homo Bukulya Gyevai Mammalia Bukulya Gyevai histochemistry Mammalia Bielanska Klepac Milkovic Paunovic Peruzovic Verhofstad histogenesis Aves Hatier medulla Mammalia Verhofstad relation with pouch develop.

Partial financial support is available in special tases only. Annual Progress Reports are available on request. They are in English and summarize the current research of the staff and guest workers (both Dutch and foreign). Persons interested in receiving reprints of the Laboratory's publications may ask to be placed on the Mailing List. They will receive a reprint check list at regular intervals. The Laboratory offers the following international facilities: a) The Central Embryological Collection, containing embryonic material of man, many mammals, and all other vertebrate classes, some of it very rare. Details will be supplied on request. A detailed catalogue in book form is forthcoming. b) The Central Embryological Library, and extensive reprint collection covering the entire field of developmental biology, with documentation and bibliographical services attached to it. Details will be supphed on request. c) International Research Groups in Developmental Biology. Aim: to stimulate research in developmental biology by introducing young scientists from different coun- tries into the field and enabling them to engage in practical international co-operation. Age limit 35, maximally 12 members. The eighth Research Group is being held during the first six months of 1976. The ninth Research Group will probably be held in the first half of 1979. International Society of Developmental Biologists (Developmental Biology section of the I.U.B.S.) The I.S.D.B. organizes an International Embryological Congress once every four years (Vlllth Congress to be held in 1977), as well as one or two regional Symposia every year.

This little book was written primarily for the educated layman but could be very suitable for a quick orientation for biologists specialized in other areas. In a very limited compass the author has admirably succeeded in presenting a readable outline of the main data of classical and experimental animal embryology, along with some hints at the most important recent advances. Much attention is devoted to the basic mechanisms of embryonic regulation and determination, with examples from both vertebrates and invertebrates. The illustrations are simple but adequate. The bibliography is restricted to important books, naturally with some emphasis on those written in French. F. S. BILLETT and A. E. WILD. 1975. PRACTICAL STUDIES OF ANIMAL DEVELOP- MENT Chapman & Hall, London. XII, 251 pp., 70 figs., 10 pis., subject and author indexes. £4,80 This is an extremely useful book and nothing quite Uke it has been available. It is meant to serve both as a practical manual and as a first introduction to animal develop- ment. The authors stress that all practical instructions are based on their personal experience in teaching undergraduates over a period of at least ten years. The scientific background provided along with the practical instructions is interesting and serves to keep 191 the book readable. It should of course be realized that many of the species treated and sources of living material indicated reflect the situation in the British Isles. Most major animal groups are represented: echinoderms, ascidians, molluscs, annelids, nematodes, insects and crustaceans; fish, amphibians, birds and mammals. Particular attention is devoted to early development. The numerous exercises described obviously vary in degree of difficulty and time required. A great deal of the practical information included will be of value to advanced research vi'orkers as well. The book is illustrated with for the most part simple line drawings and some useful photographic material. Series of normal stages are included for a killyfish, Xenopus, and the axolotl. The subject index is quite extensive. 3. E. M. DEUCHAR. 1975. CELLULAR INTERACTIONS IN ANIMAL DEVELOPMENT Chapman & Hall, London. X, 298 pp., 126 figs., 21 pis., 10 tabs., subject index. £6.50, This book is intended for students taking courses which include cell biology or developmental biology. The author is an embryologist and deliberately turns the reader's attention to groups of embryonic cells, whole embryos, and whole tissues rather than to the single cell. As such the book provides a most useful counterbalance to certain trends in the present-day teaching of biology. The treatment of the subject matter is of course highly selective, but particularly because of its very readable style and because the main problems and recent advances are well brought out, the book will serve as a stimulating "appetizer" for almost any student of developmental biology. The emphasis is on vertebrate development, but invertebrates are adduced wherever they can clarify particular points. Of particular interest are the penultimate chapter on long-distance cellular interactions mediated by hormones, and the concluding chapter on "protective interactions", which covers such subjects as cell recognition and cloning, the immune system, regeneration and repair, compensatory growth, and the properties and control of tumours. The data are not always rendered with equal clarity and precision (a case in point being the discussion of mesoderm induction in the amphibian blastula), but these are minor blemishes. The book is illustrated with simple but very adequate line drawings and a number of good photographic plates. There is a list of over 550 references, most of them recent, which lacks the bias towards Anglo-Saxon literature so often encountered. (It does have rather many mistakes in the spelling of foreign names, however.) 4. P. EMSCHERMANN. 1974. ENTWICKLUNG, Grundlagen - Erkenntnisse der tierischen Fortpflanzung und Ontogenie. 2nd edit. Herder, Freiburg, etc. Reihe Studio Visuell. 128 pp., numerous figs., combined name and subject index. DM 20.00 This book was first published in 1973. It was written for the educated layman and for secondary school and beginning university students. For the first two categories it is perhaps suitable in Germany but would be too difficult in many other countries. On the other hand, it is very suitable for use by university students, particularly there where developmental biology is being taught against a broad biological background, as in many continental universities. The emphasis is more on the morphological and phylogenetic than on the causal aspects of development, although the latter are considered in outline. The style is not exactly simple but always fluent and unambiguous. More than a third of the book is devoted to reproduction, which is seen as a necessary background to the treatment of individual development. Throughout the book examples are taken from a wide variety of animal groups. 192 A special and particularly successful aspect of the book are its illustrations. Important principles and experiments are illustrated with whole- or double-page diagrams, often on a comparative basis, which use perspective and colour to great advantage (understandably, some over-simplification has sometimes been unavoidable). The book is well produced and is concluded by a brief but adequate reading list of books. 5. H. W. SAUER. 1974. ENTWICKLUNGSBIOLOGIE; Experimente an Eiern und Pilzen Universitatsverlag, Konstanz.

It is written in a somewhat popularizing style and, rather than presenting a rounded picture, highhghts a few basic unsolved questions in developmental biology. These are illustrated with experiments on insect eggs and two simple model systems: Dictyostelium and Physarum. The lecture could be useful as collateral reading for students. It has a good selective bibliography. 6. M. SUSSMAN. 1973. DEVELOPMENTAL BIOLOGY, its cellular and molecular founda- tions Prentice-Hall, Englewood Cliffs. Foundations of Modern Biology Series.

The book is written in a very personal and captivating style, and surveys the developmental cycles of a wide variety of organisms with much emphasis on cell-biological and molecular-genetic aspects. It is suitable for both beginning and more advanced students, as the table of contents will show. The illustrations are good and there are useful lists of supplementary and advanced readings. 7. L.

Inherited variation; 5. The levels of complexity; II. The molecular view of development, 6. The synthesis of substances; 7. Timing; 8. The locahzation of substances, 9. The control of pattern Reading a new book by Bonner is always a stimulating experience. Because it is mainly synthetic in approach and extremely broad in scope, the present book seems admirably suited to convey an awareness of the great problems of developmental biology to advanced students and those standing at the beginning of a research career. For the specialist and teacher perhaps the most valuable feature of the book is that it shows convincingly that the reductionist and holist approaches to development (represented by the molecular biologist and the "developmentalist") are not mutually exclusive if seen from the evolutionary vantage point. It is therefore particularly to be hoped that the book will be read by the confirmed reductionists. With a monograph of this kind one can of course always argue with the author about what he has left out. I would take the opposite approach by pointing out how refreshing it is to see a great many points illustrated with examples that are seldom encountered in books on developmental biology: e.g. protozoans, algae, fungi, and even social insects. Since this is a book of ideas rather than facts, the references are restricted and given in the form of notes. The illustrations are hkewise limited yet serve their purpose very well. The book is admirably produced. Symposium reports 9. J. FABER and W. L. M. GEILENKIRCHEN, eds. 1975. ONTWIKKELINGSBIOLOGIE (Developmental biology) Pudoc, Wageningen. Biologische Raad Reeks, 245 pp., 74 figs., 2 tabs., subject index. Dfl. 17.50 (paper) This book is based on a didactic symposium held in the Hague in October 1974 and is therefore particularly useful for biology teachers or for general orientation. We review it here primarily for our readers in the Benelux and South Africa. Among the eight contributors there were two from England and one from Western Germany, but their contributions were translated into Dutch. The symposium centred around the nature and processing of developmental "information" (used loosely) at various levels of organiza- tion: information in the genome and the egg cortex as well as "positional" information at the supracellular level, and their interplay during development. Apart from a brief conceptual introduction by Faber, the seven main contributions are lengthy, well-illustrated reviews, some of them with long reference lists and all of them entirely up to date. An effort was made to integrate them by cross-referencing. The first (by Wessels) is a general discussion of genetic and epigenetic mechanisms in development, and sets the stage for what follows; examples are drawn mainly from the plant Kingdom. The subsequent chapters can be briefly characterized as follows: the function of the genome in development (Berendes); gene activity in early mammalian development, and sex differentiation (Gardner); determination in early animal development (Sang); pattern formation in insects (Ouweneel); genetic regulation of cell differentiation in insect spermiogenesis (Hess); the transition from the vegetative to the generative phase in plants (Linskens). The book is concluded by a glossary of some 140 terms. 194 \ 10. J. NITSCH, T. LENDER, and B. VAZART, eds. 1973.

This volume contains the proceedings of a conference held in Gif-sur-Yvette in March, 1972. Its most interesting feature was that it brought together botanists and zoologists. Of the 28 contributions eight were by zoologists. Most of the speakers were French but six came from other European countries. Most contributions are in French, but all have summaries in French and English; some are no more than abstracts. The conference was opened with three long reviews, one by Godineau on morpho- genesis and ultrastructure of the angiosperm embryo-sac, one by Clavert on polarity and symmetrization in vertebrate eggs, and one by Norreel on the culture of plant tissues and non-zygotic embryogenesis. These are followed by an interesting group discussion. Part two deals with embryonic development generally (17 papers, 4 by zoologists), and part three with the fixity or lability of axes and planes of symmetry during embryogenesis (8 papers, 3 by zoologists). The problems on which there was most exchange among botanists and zoologists were non-zygotic embryos and the localization of geometrical information in the embryo. Books of readings B. H.

XXIV, 277 pp.. 102 figs., 3 tabs. $ 4.95 (paper) This book, first published in 1964, is so well known that it suffices to mention the additions made in this new edition. Whereas the "milestones" selected for the first edition went no farther than 1939, we now have three new ones from 1954, '69, and '73. They are by Levi-Montalcini et al. (on nerve growth factor), by Ito and Lowenstein (on ionic communication between embryonic cells), and by Summerbell et al. (on positional information in the chick limb). All are provided, as the old ones, with excellent editor's comments. In addition, there is now a thoughtful, historically oriented 12-page introduc- tion by the editor. The book is well printed and the original illustrations are well reproduced. THEORETICAL AND MATHEMATICAL DEVELOPMENTAL BIOLOGY (see also 8) Treatises 12 S. L(Z)VTRUP. 1974. EPIGENETICS, a treatise on theoretical biology Wiley, London, etc. XVI, 548 pp., 269 figs., 13 tabs., author and subject indexes. £ 15.00 This interesting book, which occupied the author for half a dozen years, is a valiant attempt at synthesis of a vast number of data. The author modestly states that it is not highly original and could probably have been written 40 years ago. His major original contribution is the concept of "cell orders" and cell-type transformation, which is akin to Willmer's classification of cell types and is already familiar from his earlier publications. This review cannot be a rigorously critical one. I will only characterize the book briefly and convey my personal impressions. The author's English is very readable; it is somewhat wordy in place, but never so much as to obscure the meaning. A brief 195 introduction sets the theoretical stage. The main bulk of the book consists of three long chapters. In the first (Epigenesis: the analytic approach) animal embryogenesis is dis- cussed in terms of four large categories: (1) the embryogenetic substrate (cells, extracellu- lar components, and the fertilized egg), (2) cell division, (3) cell diversification (in which a very useful distinction is made between cell transformation and cell differentiation), and (4) morphogenetic processes, and their interactions with the other three categories. The next chapter (Epigenesis and ontogenesis) then takes up the same subject stage-wise and in a broad range of taxa. The topics discussed consecutively are cleavage, blastulation, gastrulation, larva formation, physiological events, and biochemical events. The last chapter is called Epigenesis and phylogenesis. It first discusses the main tenets of Darwinism and neo-Darwinism and then presents a systematic comprehensive theory of evolution which takes much more account of epigenetic phenomena than the former two theories, and relies rather heavily on hypothetical "large mutations". The emphasis in this book is on the whole organism and the cell. The molecular approach is viewed critically. The treatment is not very up to date: of many leading developmental biologists one finds only older literature cited. The modern work on insect morphogenesis, which has profound bearings on the issues discussed in the book, is not mentioned at all. Particularly as a work of theoretical biology the book makes a somewhat dated impression. This is not necessarily a fault, for some good "old-fash- ioned" thinking can be very wholesome, if only as an antidote to the fashions of the day. Yet, it is curious to find no mention of leading present-day theoretical biologists such as J. T. Bonner, Goodwin, Cohen, and Kauffman, to name but a few. There is no reference to cybernetics, systems analysis, or model building, although the computer is mentioned as an analogy for epigenesis. The book draws heavily on theorists of one or two generations ago, such as Woodger, Goldschmidt, Schindewolf, and Waddington. This does not alter the fact that it is an unorthodox and thought-provoking opus. Monographs 13. P. BRIEN. 1974. LE VIVANT; Epigenese, Evolution epigenetique (Propos d'un zoolo- giste) Edit, de I'Univ. de Bruxelles, Bruxelles. 155 pp. B.fr. 275 (paper) Contents: L'unite de I'etre vivant et I'epigenese; Le polymorphisme intraspecifique et I'epigenese; L'evolution biologique et I'epigenese; Les theories explicatives du fait de revolution biologique; L'evolution epigenetique Paul Brien, who died on February 19th, 1975, was one of those allround zoologists who today seem to become rare. He has always gone his own way without allowing himself to be influenced by the fashions of the day. Two strong influences do manifest themselves in this book, however: Lamarck and Driesch (though not the latter's vitalist views). At the end of a prolific life Brien has now given us his summing-up in the form of what is best characterized as "the philosophy of a zoologist". His own contributions to developmental biology (particularly asexual reproduction), on which he draws extensive- ly, are well known. Epigenesis is the key concept of the book, both for ontogenesis and evolution. The two are really one, for "la phylogenese [est le] but supreme des etudes zoologiques". Brien considers it futile to contrast "holist" and "atomist" biologists, for every biologist is both at the same time. But to him the primary problem in biology is form and organization, not the "programme" (genetic or otherwise). Biology is a science of observation and experiment (to both of which he has himself made great contributions), but it is above all a "science d'integration". "Information" contained in the germ cell and its DNA is a potentiality whici; must realize itself in the flexible programmes of development. Brien defines evolution as typogenesis, the "creative", saltatory remodelling of the entire organization of organisms. It is initiated by change mutations but for its stabiliza- 196 I tion depends predominantly on epigenetic mechanisms acting in ontogenesis. Evolution should not be confounded with speciation, which never creates anything new. Biological evolution as defined here has very little to do with natural selection in the accepted sense (which is the prime factor in speciation). These few highlights must suffice to characterize this beautifully written book, which will appeal to the theoretically minded embryologist (but probably not to the more dogmatic among the molecular biologists). We must be thankful that it was given to Paul Brien to complete this "scientific testament". 14. P. DULLEMEIJER. 1974. CONCEPTS AND APPROACHES IN ANIMAL MORPHO- LOGY van Gorcum, Assen (Neth.).

Methods in morphology; VI. The com- parative method — bone as an example; VII. The non-comparative method — bone as an example; VIII. The elements in a pattern; IX. Compromise and integration; X. The change of the pattern — ontogeny; XL The change of the pattern — phylogeny; XII. Interrelation and interaction The author of this book was trained in animal morphology by van der Klaauw and is his successor at Leiden University. It is a difficult book, which is due mainly to its subject and only very partially to the fact that the author does not write in his native language (however, a linguistic check by an English-speaking colleague could have somewhat improved its readability). It was the author's intention "to provide a background of mental procedures for the daily practice of morphological investigation". One of the reasons for this was "the increasing interest in what may be called structural thinking at all the levels of biological investigation". The book is heavily imbued with philosophy, and the concepts of holism play a particularly prominent role. The factual discussions are restricted mainly to functional morphology, particularly cranio-facial morphology and function. The first half of the book (chs. I VII) is concerned with methodology and the relation between form and function. The second half then proceeds to examine the implications of holism and system theory, resulting in what the author calls dynamic morphology. The last chapter is a brief and preliminary excursion into the differences in approach between a fundamental theory of morphology and the applications of experimental morphology. The book is very well produced and illustrated. It has a bibliography comprising close to 800 titles. An author index would have been useful. 15. P. A. WEISS. 1973. THE SCIENCE OF LIFE: the living system - a system for living Futura, Mount Kisco, N.Y. XVI, 137 pp., 4 figs. $ 7.95 The author has intended this essay both for the lay public and for his fellow scientists, "particularly those in various specialties, whose sectorial preoccupations reduce their opportunities for acquiring a catholic and balanced view of biological phenomena and problems." This, and the fact that it contains the residue of a long life of thought by a leading developmental and cell biologist, is the reason why we review it here. The book has been conceived in a "spirit of depolarization, of harmonizing conflicting doctrines . . . The theme is the recognition and scientific validation of the rule of order that pervades the universe . . ." Coming from another author, this might sound as an old man's dream, but most of us know that Weiss does not say such things lightly. The book is best characterized by another quotation from the foreword: In this book, the broader meaning of "determinacy" is subject to a critical reexamina- tion, which leads to the replacement of the rigid micromechanistic ("atomistic") 197 thinking of old by a liierarchical concept of natural "systems", in which order in the gross goes hand in hand with freedom in the small. As usual, Weiss' style of writing is both elegant and lucid, and even those who do not agree with his quaHtative systems approach will find much of value to ponder. The first one hundred-odd pages are devoted to "The order of Ufe", discussed in 30 brief sections. The remainder of the book is taken up by a Postscript entitled From life science to education for living. Two sections here are of particular philosophical interest, that on linear causaUty as the predicament of man, and that on "category versus continuum". Both bring out Weiss' emphasis on the dynamic (operationalist) rather than the static (substantialist) approach to the problems of life and hving. These lessons from a great biologist deserve to be read widely by scientists and non-scientists alike. PLANT DEVELOPMENT (general) (see also 10) Textbooks 16. D. H. NORTHCOTE. 1974.

SFr. 67.00, $ 24, 50, £ 9.80, DM 64.00 Gamma particles are found in swimming zoospores of the water mold Blastocladiella emersonii; their numbers are related to the parental phenotype. The particle has been shown to contain DNA, a store of tRNA, and the enzyme chitin synthetase. It is involved in the formation of the chitinous wall that surrounds the zoospore upon encystment (that is, the first step in differentiation). Its probable function is to sequester certain cytoplas- mic constituents until the time they are needed. This monograph presents the whole story of the gamma particle over a period of a quarter of a century in systematic fashion; this includes the development of the particles in the differentiating zoospore. A host of modern techniques has been brought to bear on the problem of the nature of the particles, and the results are set out with clarity. The book is illustrated with good drawings and electron micrographs. It has no index. 198 19. J. E. SMITH and D. R. BERRY. 1974.

Introduction: the conceptual basis of morphogenesis; 2. A cellular slime mould: Dictyostelium discoideum; 3. A plasmodial slime mould: Physamm poly- cephalum; 4. The fungal spore; 5. The vegetative state; 6. Asexual reproduction; 7. Sexual reproduction; 8. Differentiation, secondary metabolism and industrial mycolo- gy The fungi are the simplest group of eukaryotes and therefore represent an important link between the unicellular state and the higher multicellular organisms. Although their development has not been studied as extensively as that of other groups, they have already provided a number of valuable "model systems" for developmental biology. This book is therefore particularly welcome to developmental biologists who are not specialists of mycology. The book is largely based on a series of lectures given to undergraduate and postgradu- ate students. The chapters are not exhaustive reviews and are not fully documented. This makes for easy reading, however. The chapter bibliographies consist of both older and recent recommended Uterature, very conveniently classified. The treatment focuses on those processes that ultimately give rise to visible changes in structure. The book is profusely illustrated with line drawings and photographs, including a limited number of electron micrographs. 20. R. F. WILLIAMS. 1974. THE SHOOT APEX AND LEAF GROWTH, a study in quantita- tive biology Cambridge Univ. Press, London. VIII, 256 pp., 169 figs., 23 tabs., author and subject indexes. £ 6.50, $ 18.95 Contents: 1 . Introductory; 2. The quantitative description of growth; 3. Phyllotaxis; 4. Shoot-apical systems; 5. The dynamics of leaf growth; 6. The growth of an inflores- cence; 7. The growth of wheat tillers; 8. Plant growth as integration The contents of this book are almost entirely descriptive, even where (as in ch.5) data on DNA, RNA, and proteins are provided. The book is largely based on the personal research of the author and his associates, much of which is here published for the first time. Most of it centres around a sophisticated method for the analysis of the growth of primordia in shoot apices (the principles are set out in ch.2, the detailed methodology, involving three-dimensional reconstruction, in an appendix at the end of the book). In ch.8 the author suggests that the "field theory" should be modified to include mechanical as well as chemical gradients. He sees the notion of mechanical constraint as especially relevant to the genesis of pattern in plants. Ch.4 describes the shoot apices of 13 species, both mono- and dicotyledons, while ch.6 is devoted to the inflorescence of wheat and ch.7 to the growth of wheat tillers. The numerous line drawings and reconstructions are excellent and provide vivid three-dimensional images of the complicated relationships in the apices studied.

VII, 429 pp., 160 figs., 43 tabs. $ 10.60 (paper), $ 1.45 (microfiche) The analysis of plant morphogenesis at all levels from the organismal down to the molecular-genetic has in recent years made considerable progress. This symposium pro- vides a useful and interesting cross-section of these advances. Large sections of it will be read with profit by general developmental biologists, particularly those preparing a lecture course in developmental biology or genetics. There are two general lectures which are both extremely interesting to read for zoologists: one by Sussex on the applicability of concepts of animal development to plant systems, and a longer one by Stebbins on the "evolution ' of polarity and morphogenetic patterns. The latter is particularly thought-provoking. The 21 more specialist papers are arranged in five sections as follows: Morphogenesis in lower forms (4 papers); Factors affecting morphogenesis (4); Cellular factors affecting morphogenesis (4), and two sec- tions on The genetics of morphogenesis (together 9 papers). The papers are reproduced with minimal editing and therefore rather heterogeneous in style; they are well illustrated. 24. H. F. LINSKENS, ed. 1974.

S 26,95, D.tl. 70.00 This volume contains the papers read at an international symposium held in Nijmegen, Netherlands in August, 1974. By reproducing the (unedited) papers from typescript very rapid publication was achieved. Almost all of the 43 papers by authors of many nationalities are brief reports or summaries of recent research. Together, they represent a 200 good cross-section of a rapidly moving field. What is striking is the increased application of sophisticated modern techniques to this area (electron microscopy, time lapse cinema- tography, physiology, biochemistry). The classical morphological approach is in the minority (and strikingly enough restricted almost entirely to contributions from the Soviet Union). The papers are arranged in seven sections as follows: Pollen genetics (5 papers). Gamete maturation (8), The progamic phase (10), The fusion (6), Phylogenetic aspects of fertilization (3), Incompatibility (5), and Disturbed gamete maturation and fertilization (6). The numerous good photographs, electron micrographs, and line drawings are very well reproduced. INVERTEBRATE DEVELOPMENT (general) (see also 43) Treatises 25. G. H. SCHMIDT, ed. 1974.

DM 290.00 Caste determination and differentiation in social insects is a developmental process taking place at the supra-organismal level. It is based on the differential activation of specific developmental programmes in whole organisms. We briefly announce this book here because we feel it deals with problems that are of intrinsic importance for develop- mental biology in a broad sense. The book is a comprehensive treatise written by a team of 26 specialists from 10 countries. Among them are ethologists and ecologists, geneticists, taxonomists and morphologists, physiologists and biochemists. All of them are still active in research and many of the 29 chapters contain unpublished material. More than a dozen different insect groups and many separate genera and species pass in review. The contributions of authors from outside the German language area were translated into German. The book is well produced and illustrated. Textbooks 26. P. FIORONI and G. MEISTER. 1974.

DM ca. 24. - (paper) This is a laboratory guide book for students and is therefore entirely descriptive in character. Nevertheless, it could be very useful for those starting experimental work on this species. It is a digest of the essential literature, covering all phases of development and all organ systems. Moreover, it contains a "histological" Normal Table based on Naefs stages and a comparative table of Naef s and Arnold's stages. The "Practical Part" contains useful directions for obtaining and rearing egg batches and for the sectioning and mounting of embryos. The book is illustrated with very good line drawings. 201 Monographs 27. L. W. STEARNS. 1974. SEA URCHIN DEVELOPMENT: cellular and molecular aspects Dowden, Hutchinson & Ross, Stroudsburg. XII,339 pp., 41 figs., author and subject indexes. $ 20,00, £ 11.20 Contents: I. The sea urchin as a system for the study of development; U. Sea urchin gametes and early developmental processes; III. Fertilization and some associated events; IV. Cleavage and associated phenomena; V. Later stages of development; VI. Nature and activity of DNA in sea urchin eggs and embryos; VII. Polysomes in the sea urchin embryo; VIII. Maternal messenger RNA and its role in development; IX. Other aspects of the nature and function of RNA; X. Some miscellaneous problems of current interest This book is perhaps best characterized by contrasting it with the book by Giudice (Developmental biology of the sea urchin embryo, 1973), which was reviewed in Gen. Embryol. Inf. Serv. 15, 1, 1973. In the present book the treatment is at the same level but it is more selective and there is less preoccupation with methodological detail. The style is more personal and may therefore appeal more to some readers (although it definitely tends towards verbosity). Because the book is less of a compilation it reads better as a continuous story and there is more space to discuss problems of general developmental-biological interest. Both books address approximately the same audience; the graduate student and the active investigator. The data of classical experimental embryology are not separately discussed but are adduced wherever necessary. A subject that was intentionally omitted is that of interspecific hybrids. The last chapter briefly surveys problems of uptake vs. incorpora- tion of precursors, fluctuations in rate of protein synthesis during cleavage, isozymes, and reaggregation of dissociated embryos. The book is well produced but somewhat sparsely illustrated. The literature cited on the whole goes not much beyond 1970/71. There is a good subject index. Symposium reports 28 R. L. MILLER, organizer. 1974. THE DEVELOPMENTAL BIOLOGY OF THE CNIDA- RIA Am. Soc. of Zoologists, Utica. American Zoologist Vol.14 No. 2. 430 pp., 305 figs., 43 tabs. $ 6.50 (paper) This symposium was held in Washington, D.C. in December, 1972. It appears to have been the first symposium ever devoted entirely to the developmental biology of the Cnidaria. It brought together a large proportion of the world's leading investigators in this area, including several from Europe (both East and West). The main feeling the volume evokes is one of excitement: it seems that entirely new ways of looking at the develop- ment of these rather simple creatures are emerging. The volume is an extremely welcome addition to the literature, not least because attention is not devoted to Hydra alone but to many other species. The 32 papers of the symposium are partly reviews, partly research reports, and partly mixtures of the two. They are arranged in five sections as follows: 1. Gametogenesis, fertilization, and embryogenesis (6 papers); II. Cellular activities during growth and regeneration in Hydra (6); 111. Morphogenetic controls of Hydra growth and regeneration (5); IV. Morphogenetic and cellular aspects of growth in colonial hydroids (7); V. Aspects of growth and regeneration in other hydroids and the Scyphozoa (8). The approaches range from the morphological through the cell-biological to the molecular-biological. The volume is well edited and profusely illustrated. It is to be hoped that the American Society of Zoologists have laid on a good stock, for the volume may well be very popular. 202 Collections of papers 29. B. P. TOKIN. 1973.

S 12.00, DM 36.00 The basic plan of this successful book has remained unaUered, but the contents have been modernized. The morphological approach has been retained, but more attention is devoted to well-documented experimental findings and a minimum of molecular biology is sketched in. The most conspicuous changes are in ch.l (Embryology - its scope, history, and special fields), where the section on fundamental processes and concepts and that on experimental methods have been considerably expanded. A number of new illustrations have been added, particularly in Part I (Early develop- mental processes common to vertebrate embryos). The two dozen coloured figures of the second edition are now brought together in a separate section in the middle of the book, and are again reproduced in black and white at their appropriate places in the text. Although this was no doubt dictated by considerations of economy, the duplication involved is no improvement. What is an improvement is the appendix listing the illustra- tions of chick whole mounts, chick sections, and pig embryos separately in developmental sequence. This increases the book's usefulness in the laboratory. The references for collateral reading have been extensively revised and contain many more recent titles. The book is printed in a smaller but very readable type. It is well produced at a very reasonable price. 203 32. D. STARCK. 1975. FMRRYOLOGIE, ein Lehrbuch auf allgemein biologischer Grund- lage. 3rd edit. Thieme, Stuttgart. XII,704 pp., :)uo ngs., taxonomic, author, and subject indexes. DM 148.00 Although this new edition of a well-known book has been revised and somewhat extended, it has essentially remained the same book. While 20 years ago a synthesis of comparative and experimental vertebrate embryology was still feasible, so much has happened since in developmental biology (I do not even mention molecular embryology) that it would now be impossible, at least at the level of detail aimed at here. Since no consistent attempt has been made to incorporate even the most important advances, the book is now decidedly dated and conveys very little of the present-day state of embryology. Much of the Uterature is by now very old and could have been sifted to yield space for exciting new discoveries and approaches. The book undoubtedly has had its uses in the past, and many sections will continue to be useful for further study of specific topics. However, there are now more modern textbooks on the market, which are inevitably more selective but also much more balanced in their treatment. Monographs 33. A. E. BEER, D. M. COOPER and L. A.

VHI, 24 pp., 52 figs. £ 2.25 (paper) This photographic atlas is intended for the use of those active in poultry research. Its usefulness for embryologists is limited. The stages, particularly those of early develop- ment, are widely spaced. The second part, illustrating some genetic and environmentally induced defects and diseases, is clearly meant for the practical chick breeder. The colour photographs are of reasonable to good quality but some of the earlier stages (3-6 days) are difficult to discriminate. Dissertations 34. J. KOEBKE. 1974.

DM98.00, $40.00 This international symposium was held in May, 1973 at Oban, Scotland. It is mainly of interest to fish ecologists, population biologists, and taxonomists. However, among the 62 papers there are at least 10 that are of potential interest to fish embryologists. Two of these are to be found in the section on feeding and metabolism (nitrogenous wastes, nucleic acids in yolk sac), four in the section on physiological ecology (effects of various physical and chemical factors, respiratory system), and four in the section on developmental events (brain growth, effects of temperature and salinity, gynogenesis). The concluding section on the rearing of fish contains six papers, among which one deals with artificial insemination in trout. Other sections deal with population studies, distribu- tion of eggs and larvae, behaviour, and taxonomy. The book is well produced in photo-offset and sturdily bound. DEVELOPMENT OF MAMMALS AND MAN (general) (see also 57,60,64,120) Treatises 37. J. A. DAVIS and J. DOBBING, eds. 1974. SCIENTIFIC FOUNDATIONS OF PAEDIA- TRICS Heinemann, London. XVI,836 pp., 613 figs., 145 tabs., subject index. £ 13.00 Although this multi-author treatise was written to provide a scientific background for the postgraduate study of paediatrics, large parts of it may be of value to mammalian embryologists generally. The authors are mostly English specialists but there are several from other countries. The book contains a wealth of data hitherto widely scattered in the literature. It was impossible to make the coverage as balanced and comprehensive as originally intended, but this may be remedied in future editions. The treatment is authoritative and modern, and as up to date as can be expected in a book of this size. The literature references are occasionally selective but many chapters have long bibliographies. The 51 chapters are arranged in four sections as follows: I. Nature and nurture (5 chapters on genetics and nutrition); II. Climacterics (6 chs. on fetal growth, perinatal events, and puberty); III. Growth and development of systems (34 chs.); and IV. Special topics (6 chs. on paediatric epidemiology, fetal and neonatal pharmacology, and miscel- laneous subjects). In section III equal attention is devoted to the structure and function of organ systems. Although teratogenesis is not treated in its own right, abnormalities are discussed for many systems. The majority of the chapters range in length from ca. 10 to 20 pages, with some going up to 30 pages or more. The book is magnificently produced and profusely illustrated; the numerous light and electron micrographs are of superb quality. 205 Textbooks 38. K. L. MOORE. 1974. BEFORE WE ARE BORN; basic embryology and birth defects Saunders, Philadelphia, etc. XII,245 pp., 228 figs., subject index. $ 7.00 (paper) This book is meant primarily for students in the paramedical and health sciences, but can also be useful to medical and dental students. It is very similar to the author's previous book "The developing human", which was favourably reviewed in Gen. Em- bryol. Inf. Serv. 15, 2, 1974 (p. 175). The basic organization is virtually the same, but it is one third shorter. There is no additional material in small print, and the number of references has been considerably reduced. The excellent illustrations are a selection from those used for the earlier book. A few new figures were made specially for this book. Layout and printing are excellent. 39. K. L. MOORE. 1974.

Serv. 15, 2, 1974 (p. 175). The book successfully bridges the gap between embryology and adult anatomy, histology, pathology, obstetrics, paediatrics, and surgery. It is characterized by outstanding illustrations. The translation, by a Canadian anatomist, closely follows the English text also with respect to terminology, but wherever necessary the more current French terms have been added, marked with an asterisk. The type and format of the book are exactly the same as those of the original. The same holds for the illustrations, which are reproduced with the same care, except perhaps some of the photographs. Notwithstanding the paper cover, the book is considerably more expensive than the English version. 40. G. H. SCHUMACHER. 1974.

Its organization is conventional but clear. The main developmental anomalies are briefly described. A brief concluding chapter provides a survey of human teratogenesis. Most of the illustrations are original and all are very clear and well labelled. There is a list of a dozen books for further reading, most of them issued in East Germany. 41. H.

Ill of an originally French textbook, the first two volumes of which were reviewed in Gen. Hmbryol. Inf. Serv. vol.15, part 1, 1973, p. 201-202. The most interesting feature of the series is its excellent diagrammatic, multi-coloured illustrations combined with good photographs and micrographs. In this volume the development of 206 the nervous system, the sense organs, and the endocrine glands involved in neuro- endocrine correlation is placed in the perspective of adult function, while for the two first organ systems some basic information on phylogeny is also provided. The main develop- mental anomahes are briefly treated in the text, as well as illustrated. The translation is rather clumsy in places. Although the book was printed in France, the photographic illustrations are much less well reproduced than in the original book; some are so dark as to have lost all significant detail. Monographs 42. E. BLECHSCHMIDT. 1974. HUMANEMBRYOLOGIE - PRINZIPIEN UND GRUND- BEGRIFFE Hippokrates, Stuttgart. 127 pp., 138 figs., subject index. DM 64.00 This book is a sequel to the embryological atlas by the same author which was reviewed in Gen. Embryol. Inf. Serv. vol. 15, part 2, 1975, p. 186. It is in fact an extended discussion of the findings laid down in the atlas and in the author's earlier publications. The starting point is that organs at their very first inception already exhibit principles of differentiation; these are not primarily expressed biochemically, however, but in the form of "developmental movements'" which obey the laws of geometry. In his foreword the author states than an unambiguous, consistent, and therefore unified description of the development of anlagen in terms of their position, shape and structure is only possible if one has a knowledge of the developmental movements of the anlagen in question. Histochemical and biochemical changes are implicit in the developmental movements but do not play a primary or causative role. Development is spatially ordered motion of matter. Somewhat surprisingly, the developmental movements are discussed in terms of "Stoffwechselfelder" (metabolic fields). This appears to be a term without much factual content, since the attendant metabolic processes are only discussed in the most general terms and without referring to the literature. The first half of the book discusses such "metabolic fields" during cleavage and in the embryo as a whole. The second half is concerned mainly with organogenesis in the fetus. Here no less than eight main categories of "metabohc fields" are distinguished, which carry the labels of corrosion, densation, contusion, distusion, retension, dilation, parathelial, and detraction fields. What is meant by all these should be read in the original. The book is very well produced and, as usual with this author, superbly illustrated. There are no references.

XIV,344 pp., 115 figs., 10 tabs., author, sub- ject, and taxonomic indexes. $ 36.50 These are the first two volumes of a 7-volume treatise that for the first time will bring together the widely scattered data on the reproduction of all groups of free-living marine 207 invertebrates. Judging from these volumes the treatise will be an invaluable work of reference not only for reproductive biologists but also for developmental biologists working with these animals. All chapters follow approximately the same format and consecutively cover, inter alia, asexual reproduction, sex determination, germ cell origin, gametogenesis and reproductive cycles (and the factors influencing them), spawning, embryonic development, larval development, and metamorphosis. Apart from an introductory chapter on general principles by the editors, the 10 chap- ters in vol. I and the 9 chapters in vol. II each deal with a specific group. Understandably in a work of this kind, not all chapters are equally up to date; no consistent attempts at updating have apparently been made. With respect to development the coverage and illustrative material vary among chapters, and in a few cases are minimal and restricted to descriptive data. The books are very well produced and illustrated with good line drawings and with numerous beautiful light and electron micrographs, most of them original and often not pubhshed before. 44. E. S. E.

It was written by a well-selected team of 57 co-authors, most of them American but with a spattering of Europeans as well. A high multidisciplinary standard was ensured by having each chapter reviewed by at least three other specialists in the field concerned. Of the book's five parts, the entire first part, entitled Parameters of human fertility, is of great interest to embryologists. It covers ca. 250 pages and has chapters on spermato- genesis, parameters of male fertility, oogenesis and follicular growth, gamete transport, fertilization, implantation, reproductive life cycle, human reproductive endocrinology, and immunologic aspects of infertility. All these are well written , well organized, and fully documented. Together they present the latest state of the art in an area where rapid advances have been made during the last decades. The remaining four parts of the book deal with fertility inhibition, consequences of fertility inhibition, stimulation of fertility, and social aspects of population control. Great care has been devoted to the many illustrations, all of which were specially prepared for this book. The numerous photographs and electron micrographs are very well reproduced. Many very clear summarizing diagrams are also included. The produc- tion of the book is excellent. 45. B. LOFTS, ed. 1974. PHYSIOLOGY OF THE AMPHIBIA.

Moore, ed.). A third volume is to be published in the near futur'i. The present volume was written by an international team of specialists and brings togethei a wealth of information otherwise often not easily found. The topics of the various chapters are interrelated and further integration has been attempted by cross-referencing. The scope of the book transcends the strictly physiologi- 208 cal. Chapter 5 is by far the longest (over 200 pp.) and has an enormous reference hst. All chapters are up to date till 1971 or '72 except the last, which goes no further than 1969. Most chapters are profusely illustrated. The reproduction of photographs and electron micrographs is fair to good. Monographs 46. A. BOLOGNARI. 1974.

Ffr. 99.10 (paper) This monograph deals in concise fashion with the whole of human sexual develop- ment, from fertilization till the emergence of phenotypic and socio-culturally determined differences in sexual behaviour. This is a complicated subject that could easily fill a fat volume. Here the treatment is extremely condensed, which makes the book difficult to read in places, particularly because much knowledge of various areas of science is presupposed. The terminology used is not always unambiguous. On the other hand, the most recent views at the time of writing are incorporated and the documentation is extensive, so that the book is useful as a first introduction for advanced students and beginning investigators. The book is illustrated largely with coloured diagrams. These are not always very successful and the colours are painful to the eye. A general flaw of the book is the lack of correlation between text and figures; the latter are therefore often difficult to understand and the captions are insufficient to remedy this. The chapter bibliographies together number 21 pages of small print. There is a useful tabular survey of the ontogenesis of sexual characteristics. 48. L. GALLIEN. 1973.

Sommaire general This clearly written and extremely well-organized account of the cytology and genetics of sex could be of great value to both advanced students and active investigators. The more the pity that the most recent advances could not be incorporated. Perhaps the author can be persuaded to update the book fairly soon, particularly since an English version seems to be planned. The book may be regarded as a companion volume to the author's book on sex differentiation reviewed below (no. 49). The table of contents speaks for itself. Selected examples are drawn from the whole animal kingdom except the protozoans. The concluding chapter is mainly a brief sum- mary of the present-day cytogenetic theory of sex determination. The book is profusely illustrated, mainly with good line drawings. The bibliography comprises over 500 titles; the most recent literature dates from 1969/70. 49. L. GALLIEN. 1973.

Biochimie de la differenciation sexuelle chez les Vertebres The author of this monograph is one of the doyens in this field, and he has given us a clearly written, very complete, and critical expose. The only thing to be regretted is that it is not entirely up to date. For instance, two recent and already influential theories, those of Ohno and Mittwoch, are not mentioned. Nevertheless, a book like this was urgently needed, and it will be of great value both to students and investigators. Understandably, the problem of the germ line and the determination of primordial germ cells is left out of consideration. (See review no. 48 above.) The table of contents speaks for itself. The book is concluded by a brief resume of the five main phases of vertebrate sexual development, exemplified by the author's favourite object, Pleurudeles, and by a very useful chart summarizing almost everything that is known about these phases in amphibians. The book is profusely illustrated with line drawings and photographs. The literature list comprises over 400 titles; with very few exceptions the most recent titles date from 1969. 50. W. P.

The topics selected are those for which comparative data are available and whose nature permits speculation on their possible phylogenetic significance. All chapters are authoritative and systematically organized reviews. The book is well produced and the numerous light and electron micrographs are of very good quality. 51. D. M. PHILLIPS. 1974.

Most of the contributors were Americans, but some other countries were also represented. Most papers range in length from about 15 to 30 pages and consist of a mixture of review material and summaries of original research that was recent to very recent at the time of writing. The 16 contributions are arranged in four sections as follows: 1. Placental structure (2 papers on transmission and scanning electron microscopy); 2. Transport and exchange mechanisms (7 papers); 3. Metabolic and endocrine aspects (5); 4. Clinical aspects (2, of which one on the fetus as a homograft). The electron micrographs in section 1 are well reproduced. The book is luxuriously produced and therefore rather expensive. 55. S. NATELSON, A. SCOMMEGNA, and M. B. EPSTEIN, eds. 1974.

The book has a strongly clinical slant, yet about ten contributions are of potential interest to mammalian and human embryologists. The 29 contributions vary widely in length and are arranged in four sections. In section I (Formation and composition) we mention reviews on development and func- tional morphology of the amnion; on dynamics of amniotic fluid; on interrelations between AF and urine; on urea and glucose concentrations; on osmolahty, non-protein nitrogen, and bilirubin; and on uric acid, creatinine, and total protein. A research report deals with epinephrine and norepinephrine. Section II (Immunoglobulins and other proteins) contains two reports of potential general interest, as well as two contributions dealing with the Rhesus problem. The remaining sections are entitled Composition changes with fetal maturity and Diagnosis of genetic disorders, and are of mainly clinical interest. The book is well produced and well illustrated. 56. J. S. PERRY, ed. 1974. IMPLANTATION Blackwell Scient. Publ., Oxford, etc. J. Reprod.

The proceedings consist of eight papers, five of which are reviews or mixtures of review and research material. The authors came from the U.K., Sweden, Belgium, the U.S.A., and Australia. Morphological, physiological, and experimental aspects of normal and delayed implan- tation are considered. A special feature is the inclusion of two papers on marsupials and one on the roe deer. Several papers contain beautiful photographic plates. 212 TERATOGENESIS (see also 38,39) Treatises 57. D. H. M. WOOLLAM and G. M. MORRISS, eds. 1974. EXPERIMENTAL EMBRYOLOGY AND TERATOLOGY.

The reviews it contains cover both basic and applied aspects of (mainly mammalian) normal and abnormal development. The editors would welcome suggestions for articles falling within this general scope. The reviews contained in this first volume hardly need recommendation. The book is well produced in photo-offset and the photographic illustrations are well reproduced. Monographs 58. M KARKINEN-JAASKELAINEN. 1973.

It is one of those instances where one wonders whether publication of symposium proceedings more than a year after the event is of much use, especially in the case of a rather informal affair like this symposium. Nevertheless, the book contains a certain amount of information that might still be unknown to some teratologists and pediatricians. Some of this is in the group discussions. The material in the book that seems of most interest to our readers consists of a thoughtful analysis of teratogenic testing procedures by Layton, a paper by Skalko on the incorporation of teratogenic agents into the mammalian embryo, a review of mechanisms of cleft palate formation by Larsson, and a paper by Runner on micromelia in the chick 213 traceable to defects in dehydrogenase and molecular assembly. A brief paper by Clarke Fraser on maternal effects in congenital malformation is also interesting. 60. A. G. MOTULSKY and W. LENZ, eds. 1974.

Causation: epidemiological and laboratory clues (environmental causation, mutagenicity testing); V. Modern approaches to diagnosis and prevention (intrauterine diagnosis, disease prevention, genetic counselling); Workshop sessions (summaries) This is the report on the Fourth International Conference on Birth Defects held in Vienna in September, 1973. As the table of contents shows, in the programme much emphasis was placed on basic biological aspects, and this is the reason why the book is of interest to a much broader circle of readers than the title suggests. Almost all of the 31 contributions in the five main sections are short to medium-length authoritative reviews written by outstanding experts from many different countries. Section I has five interesting papers on molecular-genetic and chromosome studies and on cell fusion. The papers of most immediate interest to developmental biologists are to be found in sections II and III. We particularly mention the contributions by R. G. Edwards and by Nossal in section II, and those by Cattanach, Jost, Ohno, and Goldstein and Wilson in section III. Section IV has a paper by J. G. Wilson on primate teratogenesis. Further items that are well worth reading are the keynote address by Ebert and the discussion of ethical issues by Motulsky. Luxury production, though pleasing, has led to an inordinately high price.

Contributions were presented by fourteen leading specialists, twelve from the U.S.A., one from England, and one from Australia. Collectively they show how important recent advances in both cancer research and immunology are (or can be in the future) for advancing our insight into fundamental processes of development. The contributions are reviews or mixtures of review and recent original material, and most of the authors have made an effort to bring out the relevance of their subject for developmental biology (particularly the problem of the differentiated state). The four- teen contributions are arranged in five sessions: Multipotentiality of the tumorous state; Cell proliferation, differentiation and neoplasia; Cell surface changes; Transformation of cells in culture; and Immunity and oncogenesis. The cell types involved in the work reported are usually human or mammalian cell lines but include such things as plant tumour cells and teratocarcinomas. There are some interesting speculations on transla- tional control of neoplasia and on the role of reverse transcriptase. 64. K. S. MOGHISSI, ed. 1974.

Xll,334 pp., 94 figs., 45 tabs., author and subject indexes. $ 24.50 This symposium was held in Detroit in November, 1971. Consequently it is probably partly out of date at the time this review is printed. The book is of most interest to pediatricians and bio-medical researchers, but some contributions are certainly of interest to mammalian embryologists. Most of these are found in Sections One and Two: MetaboUc and nutritional factors affecting fetal growth and development (5 papers), and Endocrine and environmental factors (5). Of these ten papers, half are longer reviews and the rest shorter research reports. Of the reviews we mention one by Villee on endocrine regulation of pregnancy and fetal development, one by Jost (Paris) on mechanisms of normal and abnormal sex differentiation in the fetus, and one by Gardner (now in Oxford, England) on micro- surgical approaches to the study of early mammalian development. Section Three is entitled Recognition, prevention and management of birth defects. The book is well produced but the photographic illustrations are not too well reproduced. Some figures surprisingly lack captions. 65. W. NAKAHARA, T. ONO, T. SUGIMURA, and H. SUGANO, eds. 1974. DIFFER- ENTIATION AND CONTROL OF MALIGNANCY OF TUMOR CELLS University Park Press, Baltimore, etc. XX, 554 pp., 250 figs., 150 tabs. $39.50, £ 18.00 The relationship between differentiation and cancer has been formulated in two ways: cancer is a disorder of differentiation, or oncogenesis is blocked ontogenesis. The recent advances in the molecular and cell biology of cultured cells have shown that the problems in the two areas are remarkably similar. Therefore, this symposium volume is of consider- able interest to developmental biologists. The symposium was held in Tokyo in 1973 and had as participants 1 1 renowned specialists from Japan, 12 from the U.S.A., and 7 from Western Europe. The level of the papers is remarkably uniform, and they are well edited. They all summarize or review very recent research by the authors and others, much of it 215 previously unpublished. A maximum amount of data is presented in a minimal space. The 29 papers are arranged in five sections as follows: Regulation of gene expression (10 papers); Phenotypes of tumor cells (5); Control of differentiation; induction (5); Control of differentiation: suppression (3); Tumor reversal (6). We mention the following contributors: Tomkins, Ohno, Paul, G. Schapira, Rutter in the first section (which is of the most general interest), and F. Schapira, Prasad, Silagi, Holtzer, Ono, Pierce in other sections. All contributions are followed by highly pertinent discussions. The book is very well produced and illustrated but unfortunately has no indexes. 66. M. WINICK, ed. 1974. NUTRITION AND FETAL DEVELOPMENT Wiley, New York, etc. XII, 188 pp., 70 figs., 41 tabs., subject index. $ 14.50, £ 7.90 This book is based on an international symposium held in New York in November, 1972, and will primarily be of interest to paediatricians. During the past five years or so evidence has accumulated for a relationship between early malnutrition and subsequent retarded brain development. The book reviews the latest evidence available in 1972. Of the eight papers the first three are of most direct interest to our readers: Cellular changes in intrauterine malnutrition (by Brasel, 14 pp.); Biochemical markers of intraute- rine malnutrition (by Metcoff, 18 pp.); and Pathophysiologic changes in intrauterine malnutrition (by Minkowski et al, 34 pp.). All of these are reviews of recent work on mammals and man. The book is well produced and illustrated. REGENERATION, RENEWAL (see also 28,29,73,92,1 19) Textbooks 67. R. J. GOSS. 1974. REGENERATION; Probleme - Experimente - Ergebnisse, Translated from the English by K. Bergerhoff Thieme, Stuttgart. VI,288 pp., 128 figs.. 2 tabs., subject index. DM15.80 (paper) This is the translation of a highly successful book which appeared in 1969 and was reviewed in Gen. Embryol. Inf. Serv., Suppl. 13 (1970), p. 14. Superficially the translation reads well, but if it is compared with the original it becomes apparent that the translator does not know quite enough English and moreover is not an expert in the field. This has led to all sorts of confusing mistakes and incorrectnesses. One of the worst is the translation of "territory" by "Feld". The numerous excellent illustrations are well reproduced and the photographs have not lost too much detail. Names of authors have been removed from the index. 68. T. LENDER. 1974. LA REGENERATION ANIMALE Presses Universitaires de France, Paris. Collection SUP; Le Biologiste 6. 192 pp., 73 figs., subject index Contents: I. Quelques exemples de regeneration dans le regne animal; II. L'origine et la nature des cellules de regeneration; III. Influence du systeme nerveux et des hormones sur le pouvou- de regeneration; IV. Les mecanismes de la morphogenese This clearly organized little book is suitable for biology students, but because of the selective treatment and the limited number of references it is hardly useful to active 216 I investigators. The text reads well but there is little room for the discussion of divergent views. A major issue like that of the reaUty of neoblasts (which is much debated today) receives a conservative treatment. Morphogenesis in the regenerate is discussed almost exclusively in terms of inductive and inhibitory actions; this is one way of looking at the prol^Iem, but certainly not the only one. The brief discussion of the relationships between regeneration and regulation is unsatisfactory, and so is the equation of the stump ("la base") to a morphogenetic field; it is not at all clear what the author means. The major animal groups in which regeneration has been studied are adequately covered, but it is a pity that no mention is made of the important recent work on gradients in the insect limb. The book is illustrated with simple but adequate line drawings. A few dozen key references only are given in the form of footnotes. The subject index is very brief. Monographs 69. L. D.

Regeneration and irradiation This book was first published in Moscow in 1972. It is a collaborative effort by ten workers at the Institute of Human Morphology, Academy of Medical Sciences of the U.S.S.R. They have made an inventory of the conditions of organ regeneration in mammals, a subject on which during the last quarter of a century much work has been done in the USSR which is generally not very well known in the West. This translation is therefore particularly welcome. The table of contents speaks for itself. In most chapters the subject matter is arranged according to separate organs. Liozner has provided a lengthy introduction and conclusion. Here the emphasis is on general principles and often involved theoretical arguments, while a certain amount of polemics is also included (particularly with Polezhaev's views). The translation is competent. The book is sparsely illustrated; some of the micrographs are very black, but the publisher is not to blame for this. The bibliography comprises close to 900 titles, over half of which refer to Russian work. There are no indexes. 70. N. A. SVENDGAARD, A. BJORKLUND, and U. STENEVE 1975.

All but one of these are condensed but very readable reviews of areas in which major advances have recently been made. Among them are neuronal specificity, brain metabo- lism, and what may be loosely called plasticity in the nervous system (both embryonic and postnatal). Because of their terseness the reviews are also eminently suited for the non-specialist who wants to bring himself up to date. We specifically mention the following contributors: Prestige, Gaze, Mark, Balazs, Keating, Blakemore, and Dobbing. Most of the hterature cited is recent to very recent. Several papers contain clear diagrams especially made for this issue. 218 74. J. MILAIRE. 1974. HISTOCHEMICAL ASPECTS OF ORGANOGENESIS INVERTE- BRATES. Part I.

DM1 10.00 Thfe first part of this supplement deals with the skeletal system, limb morphogenesis, and the sense organs. A forthcoming second part will deal with the CNS, the urogenital system, and the ectodermal derivatives. The subject matter in the first part is discussed very ably and sensibly against a background of experimental-embryological data obtained mostly in birds and amphibians. Most of the descriptive data and illustrations refer to various mammals and the chick. In all cases organogenesis is considered from its very first beginnings. All illustrations are original and very good; several are in colour, the substances shown are RNA, glycogen, alkaline and acid phosphatase, and ATP and AMP phosphohydrolases. The 15-page bibliography is up to date until 1970; later references are relatively scarce. 75. W. J. MOORE and C. L. B. LAVELLE. 1974. GROWTH OF THE FACIAL SKELETON IN THEHOMINOIDEA Academic Press, London, etc. VIII, 236 pp., 30 figs., 35 tabs., subject index. £ 6.60, $ 17.50 Contents: 1 . The pattern of growth in the facial skeleton of Homo sapiens; 2. Sites of facial growth in Homo sapiens; 3. The control of facial growth; 4. Comparative aspects of facial growth with special reference to the Hominoidea This book is of much wider interest than to members of the orthodontic profession alone. Indeed, it has been the aim of the authors to distill what is essential from the recent, predominantly clinical Uterature, and to divest it of "esoteric" terminology so as to make it accessible to all workers interested in skeletal growth and its regulation. Only the normal pattern of growth is considered. Chapter 1 is the longest, its bulk being devoted to the prenatal and postnatal growth patterns and the growth of the dental arches. Ch.2 describes the sites of growth in the cranial base, the upper facial skeleton, and the mandible against a background of general principles of bone growth. Ch.3 then examines the control of facial growth. It has sections on differentiation and early morphogenesis, on later growth, and on mechanisms of growth control. The latter two sections rely strongly on Moss's concept of "functional components". The subject matter and conclusions of the final chapter are mainly of phylogenetic interest. The book is well produced and illustrated with clear line drawings. 76. S. C. J. van der PUTTE. 1975. THE DEVELOPMENT OF THE LYMPHATIC SYSTEM IN MAN Springer, BerUn, etc. Advan. Anat. Embryol.

Of the 28 papers, some 16 are of direct or potential interest to our readers. Among the authors of these, five are from France, four from the U.S.A., and the remainder from four West-European countries. The papers in question vary in length: some are research reports, others are reviews of recent research. They are in French or English, and most have summaries in both languages. About half deal explicitly with the human brain. The papers of interest to our readers are to be found in the following sections: Cell biology and morphology (5); Biochemistry (9); Electrophysiology (2). Other sections deal with the role of sensory stimuli and nutrition, and with behavioural aspects. The book is well printed and illustrated, but also rather expensive. It has no indexes.

Vol.2 Cellular genetics, development and cellular specialization Academic Press, London, etc. XVII1,597 pp., 217 figs., 21 tabs., author and subject indexes. £ 1 1.30, $ 29.25 This book is one volume of a 4-volume collaborative textbook written by a large team of mo.stly British authors. It is meant mainly for the use of senior undergraduate students but can be very useful to research workers who want information outside their own fields of specialization. It is quite definitely not a work of reference, and reference lists were intentionally kept brief. No comprehensive cover of cell biology was attempted; on the other hand, the editors have devoted much attention to the coherence among the numerous chapters. All chapters are moreover well written and clearly organized. The chapters in this volume which are of immediate interest to our readers are that by Brynmor Thomas on the kinetics of cell production, and two concise chapters by R. Bellairs (together occupying 64 pages) which deal with cell differentiation, pattern formation, cell communication, cellular growth, and some special aspects of development (the oocyte and fertilization, the lens, the formation of muscle, and migratory cells). These chapters are ideally suited as a first introduction into the problems of modern vertebrate embryology. 222 Other chapters in the book deal with biochemical genetics, mammalian and human cytogenetics, sex chromatin, ageing, and a number of specialized cell types. This last part is continued in vol. 3. Vol. 4 deals with intracellular control, the control of protein synthesis, and intercellular regulation. Vol. 1 is entitled The cell and its organelles. The books are well produced and illustrated. Monographs 89. A. AHONEN. 1973.

It concentrates on the development of cells in vivo, particularly in those tissues on which most information is available: nervous system, muscle, bone and connective tissue, skin, gonads, blood, and lymphoid organs. Morpholo- gy, physiology, and biochemistry receive equal attention. All chapters are well organized and clearly written. Of particular value are the excellent opening chapter by Brown and Jones on basic concepts of differentiation and growth of cells (52 pp.) and the concise but very clear concluding chapter by Bellamy on cellular ageing. Some of the chapter bibliographies are quite extensive. The book is well illustrated; particularly the numerous photographic plates are excellent. For a book of this kind the index could have been more detailed. 91. G. M. PADILLA. I.L.CAMERON, and A.ZIMMERMAN, eds. 1974. CELL CYCLE CONTROLS Academic Press, New York, etc. X,370 pp..

It is a series of concise reviews written by an international team of specialists and dealing with the control of the cell cycle in many different lower and higher eukaryotic cell types. Unpublished material is included in most of the reviews. The 22 reviews are grouped into three sections as follows: Regulation and timing of 223 the cell cycle (8 papers, headed by a review by Zeuthen); Gene expression in the cell cycle (8, headed by Mitchison); Nuclear and chromosomal activity in the cell cycle (6, headed by Mazia). 92.

Morphology, taxonomy and general biology (Vivier); 2. Mating type determination and development (Butzel); 3. Surface antigens (Finger); 4. Behavior and motor response (Dryl); 5. Growth patterns and morphogenetic events in the cell cycle (Kaneda and Hanson); 6. The structure oi Paramecium as viewed from its constituent levels of organization (Ehret and McArdle); 7. Nutrition (Van Wagten- donk); 8. Intracellular particles (Soldo) As the editor of this book says in his preface, topics were selected for inclusion that had not already been extensively discussed in other books and recent reviews. It follows that the book cannot claim to be entirely comprehensive. There is also some overlap among chapters, and no attempt at unification of terminology has been made. Yet the individual chapters are valuable reviews and reference sources, which also contain much new material. All chapters are well organized and have been updated by means of addenda. Obviously it is ch.5 (44 pages) that is of most direct interest to our readers. Unlike the other chapters, it is largely based on the authors' own research on carefully timed interfission stages. Three phases are distinguished: post-fission, morphostatic, and mor- phogenetic. Stages of stomatogenesis are compared with those in other hymenostome ciliates. To explain overall growth patterns and the shape of the cell the authors postulate a gel-like "framework" underlying the visible surface structures. The book is handsomely produced and superbly illustrated with numerous light and electron micrographs and drawings. It is concluded by a bibliography on Paramecium covering the two decades since 1953 (1354 titles). Regrettably, there is no author index. 224 Dissertations 95. U. P. van der WAL. 1974.

Cold Spring Harbor Conferences on Cell Proliferation vol. 1 . XIV, 1029 pp., 385 figs., 220 tabs., subject index. $ 30.00 This is the report of the first conference on cell proliferation held at the Cold Spring Harbor Laboratory. It was an experiment, but a highly successful one. Here one finds in one mammoth volume a cross section through nearly all the new frontiers of this relatively young branch of biology. Almost all the leading investigators were there, most of them from North America but with a sizeable proportion from other parts of the world, particularly the United Kingdom, Switzerland (Basel), and Israel (Rehovot). The 78 brief to medium-length papers are arranged in five sections as follows: Growth factors (11 papers). Viral transformation, revertants, and mutants (7), The cell surface (27), Biochemistry of the cell cycle (20), and Prohferation kinetics, differentiation, and external influences (13). Most, but by no means all papers deal with hemopoietic cells, lymphocytes, and fibroblasts, and about half report work on normal rather than neoplas- tic cells. As is brought out in the concluding summary by Stoker, most of the conference dealt with three main aspects: the incoming signals, the role of the cell surface, and intracellular switches and responses. The book is well produced at a reasonable price. The subject index is extensive. 97. R. L. DAVIDSON and F. F. DE LA CRUZ, eds. 1974. SOMATIC CELL HYBRIDIZA- TION Raven, New York. XVI1I,295 pp., 58 figs., 57 tabs., author and subject indexes. $ 23.25 This international conference was held in March, 1973 in Winter Park, Fla. It was attended by 48 speciaUsts from the U.S.A., the United Kingdom, and various Western- European countries. All the major areas of research involving cell hybridization were covered. The discussions held at the conference are included, complete with literature references. The 33 papers are arranged in four sections as follows: Chromosome segregation and gene linkage in hybrid cells (8 papers). Viruses, cell membranes, and malignancy in fused cells (5), Regulation of gene expression in hybrid cells (16), and Gene expression in heterokaryons (4). Clearly the last two sections are of most interest to developmental biologists. Section III is opened by a review on the control of expression of differentiated functions in cell hybrids by Davidson (20 pp.), and contains a commentary by Ephrussi in which he calls attention to the fundamental enigma of embryonic determination. Section IV starts with a review on the regulation of gene expression in heterokaryons (with 225 emphasis on events in the nucleus) by Ringertz (26 pp.). It also has a brief paper by Graham on the fusion of mouse blastomeres. The book is very well produced and illustrated. 98. D. B. DRACHMAN, ed. 1974. TROPHIC.FUNCTIONS OF THE NEURON New York Acad, of Sciences, New York. Ann. N.Y. Acad. Sci. Vol. 228. 423 pp., 171 figs., 38 tabs. $ 31.00 (paper) This is the report of a conference held in March, 1973, in which the large majority of participants were American. Most of the 29 contributions are reviews or mixtures of review and research report. Virtually all the trophic interactions discussed, both within the nervous system and between neurons and other target cells, fall into three categories: formation of cell connections, maintenance of the integrity of target cells, and regulation of the properties of target cells. Papers of direct interest to developmental biologists are to be found particularly in Section I (Development of neural connections; 4 papers), and section VI (Other trophic systems; 10 papers). The latter section features such systems as the regenerating amphi- bian limb, the neuromuscular junction, the taste bud, spinal motor neurons, cortical neurons, and ganglia. One paper deals with the insect nervous system. Other sections deal with denervation and regulation of muscle and with possible mechanisms of neurotrophic action. The volume is adequately illustrated. 99. A. A. MOSCONA, ed. 1974. THE CELL SURFACE IN DEVELOPMENT Wiley, New York, etc. XIV, 334 pp., 127 figs., 37 tabs., combined author and subject index. $ 24.00 This volume contains the proceedings of a symposium held in Montreal in August, 1973. Unhke many other similar books it will not be rapidly out of date. This is because the authors have made an effort to give their reviews a broad background, and because theoretical aspects and possible new approaches are frequently considered. The book is therefore of interest to all developmental biologists and not only to those working on the cell surface. Of the 27 contributors, 23 are from North America. Not all of the 16 reviews strictly fall within the subject defined by the title. This holds for the chapters on cartilage differentiation, somatic cell hybridization, and development and cancer. Of the others one deals with artificial lipid bilayers, the remaining ones with a wide variety of animal cell types and approaches, which cannot all be enumerated. Suffice it to say that every chapter is thoroughly up to date and has something new to offer in the way of findings or ideas. Of course not all areas of membrane biology relevant to development are represented, but the selection is varied and well considered. The production of the book and especially the reproduction of the numerous photo- graphs and electron micrographs is of high quality. 100. M. PRUNIERAS, L. ROBERT, and C. ROSENFELD, eds. 1973.

(near Paris) in June, 1973. Of the four sections (24 papers) only section I 226 (Differentiation - molecular and cellular aspects) is of direct significance to develop- mental biologists. It contains 1 1 reviews and research reports. Of the former we mention Cellular and tissue differentiation of mesenchyme (Robert and Robert), Collagen biosynthesis and its regulation (Frey), and Interactions between sclerotome and periaxial extracellular material in vertebral cartilage differentiation (Stru- del). The following research reports may be mentioned: Synthesis and secretion of collagen by fibroblasts (Frey et al), Differentiation of elastic tissue in the aorta (Courtois et ai), and Tooth morphogenesis and cytodifferentiation in vitro (Ruch and Karcher). All these papers are in French but all have Enghsh summaries. Collection of papers 101. I. GERSH, ed. 1973. SUBMICROSCOPIC CYTOCHEMISTRY Academic Press, New York, etc. 2 vols.

XVI1I,245 pp., 192 figs., 6 tabs., author and subject indexes. $ 22.00 This book is not a treatise but rather the report of an extensive and very original project carried out by the editor and his associates over a period of more than a dozen years. It started with the introduction of new methods for rapid freeze-drying of cells followed by postfixation and staining by means of reagents in the vapour phase. These techniques were subsequently appUed to a great variety of biological material. The studies reported in this book centre on two main topics: morphological aspects of genetic control in the nucleus, and the role of the cell in the formation of extracellular components. The approach is largely cytochemical, but with a strong emphasis on morphology. Vol. I deals mainly with distribution patterns of nucleic acids in relation to protein synthesis (particularly the conformation of DNA in first-, second- and higher order helices and its association with the nuclear membrane). It is perhaps of most interest to developmental biologists, because the findings and the conclusions (and informed specula- tions) based on them have a profound bearing on the problem of gene regulation (at a relatively coarse level) in determination, cell heredity, differentiation, and cell matura- tion. This work surely begins to fill the gap between prokaryotes and eukaryotes, and it is surprising that this was possible by meticulously applying an essentially morphological approach! In vol. II most of the emphasis is on the molecular and macromolecular organization of (particularly internal) membranes, and on the origin and distribution of the major macromolecular aggregates of connective tissue. We briefly enumerate here those of the materials studied which are of particular interest to developmental biologists: Drosophila syncytial blastoderm, Z)raiO/;/!//a salivary gland, Drosophila imaginal discs, various differentiated and developing mouse cell types, metaplastic mouse vaginal epithelium, cat spinal ganghon cells during nerve regeneration (all in vol. I); epiphysial chondrocytes of rat tibia, rat cartilage matrix (in vol. II). Vol. II is concluded by a chapter by Gersh entitled Summary, synthesis, and speculations. All 25 chapters have a brief summary. The books are beautifully produced and illustrated mainly with a profusion of superb light and electron micrographs, supplemented by explanatory line drawings. 227 DEVELOPMENTAL BIOCHEMISTRY, MOLECULAR BIOLOGY (see also 6,19,27,71, 95,97,99,100,107,114) Textbooks 102.

VIII, 197 pp., 67 figs., author and subject indexes. F.fr. 98 These two books are basically very similar and are therefore reviewed together. Both were written primarily for students, but the French book presupposes more knowledge of molecular biology and is slightly more detailed in certain areas. It also gives more literature for further reading, which in the English version is restricted to a minimum. Both books could also serve as an introduction for molecular biologists into the major problems and approaches of the complex science of embryology. The arrangement of the subject matter is largely but not strictly parallel. Both books contain an outhne of the basic facts of descriptive and experimental embryology. They then proceed to discuss in systematic fashion the molecular-biological aspects of gameto- genesis and egg maturation, fertilization, cleavage, early embryogenesis in invertebrates and vertebrates, nucleo-cytoplasmic interactions, and finally (and very briefly) later cell differentiation. The books are lucidly and critically written, as we expect from this author. Yet the present reviewer is inclined to regret two things: first, that virtually no attention is devoted to early mammahan development, and second, that the author considers the concept of determination as so ambiguous that he has decided to leave it out of the discussion. True, little is known about the molecular biology of determination, but it is so basic to developmental biology that is should present a major challenge to the molecular embryologist of tomorrow. The illustrations are practically the same in the two books. They include many good photographs, which however in the French version (printed in Spain) are rather badly reproduced. The French book is also by far the most expensive. 103. D. E. S. TRUMAN. 1974.

It is highly sucessful in all respects: clarity of style, modernity of treatment, selection of examples, and illustrations. The treatment is in the main restricted to higher vertebrates. Notwithstanding the limited size of the book the student really gets a grasp of the subject and of its main theoretical superstructure. The book also seems almost ideal as an introduction into molecular embryology for zoologists and geneticists. The book is well produced and has an excellent bibliography of 160 titles. 228 Monographs 104. O. GREENGARD, ed. 1973.

Many have extensive bibliographies (50-150 titles). The editor writes in her Preface: "The sudden growth of precisely defined, quantita- tive information about the changing compositions of tissues in the developing animal has stimulated the assembly of this Special Issue". The focus is on late prenatal and postnatal stages in laboratory mammals, man, and birds. Many papers deal with enzymes and (precocious) enzyme induction, but several treat other cell and tissue constituents, organelle activities, effects of hormones and cycUc AMP, specific binding proteins, etc. Cultured cells are used in several studies. The organ most frequently studied is the liver, but at least half a dozen other tissues are dealt with in one or two papers. The brief subject index is rather inadequate. 105. J. PAUL, ed. 1974.

The role of chromosomal proteins as gene regulators The MTP International Review of Science is a new venture in scientific publishing. Its basic concept is to provide regular authoritative reviews of entire disciplines which are to be updated at regular intervals. The series addresses both investigators and advanced students and is carefully edited. The editor of the present volume has had in mind a wider group of biologists than those actively engaged in the area concerned, as well as biochemists who are put off by the complexities of biology. He has provided an introduction and five brief editor's comments between chapters, which admirably serve to make the volume read as a continuous story. The ten essays making up the volume are written by an international team of outstanding experts and are well organized. They range in length from about 20 to about 50 pages of smallish type (the chapter on sea urchins is only 10 pages long). The volume describes the scene as it was in mid-1973. The book is well produced, and illustrated mainly with numerous graphs. The index is good and the price very reasonable. 229 Symposium reports 106. E. D. HAY, T.J.KING, and J.

The 30th Symposium of the Society for Developmental Biology was held in June, 1971, and the book has therefore been very long in the making. It is a heterogeneous collection of reviews with a strong -emphasis on cell biology, and several contributions have no direct developmental relevance. We will restrict ourselves to briefly characterizing the contents. Papers of most immediate interest to developmental biologists are one by Burger on the role of the cell surface in cell growth and cell transformation, one by Cohen and Taylor on epidermal growth factor, one by O'Malley et al. on hormonal control of chick oviduct growth and differentiation, and one by McCarthy and Janowski on the separation of active and inactive segments of eukaryotic chromatin. Three papers deal with the formation and organization of plant cell walls, one with tumour growth, one with mammalian chromo- some organization, and the remainder with strictly molecular-biological topics.

Vol. 2, Eucaryotic chromosomes Wiley, London, etc. XIV,467 pp., 1 15 figs., 7 tabs., subject index. £ 8.00 (cloth), £3.95 (paper) Contents: 1. Structure of the chromosome; 2. Chromosome functions during the cell cycle; 3. Protein components of the chromosome; 4. Sequences of eucaryotic DNA; 5. Transcription and processing of RNA; 6. Control of transcription; 7. Interactions between nucleus and cytoplasm This first volume of this book dealt with bacterial genomes. The present volume is concerned largely, though by no means entirely, with the chromosomes of higher vertebrates (particularly mammals). Together they constitute the first comprehensive and critical review of this whole area, and as such will be of great value to advanced students and molecular embryologists. Vol. 2 is perhaps best characterized by a quotation from the preface: This book . . . presents a view of gene expression in higher cells; and attempts to pose some of the questions which we should at present ask in cell biology and to suggest some of the lines along which solutions may come. 1 have been as concerned to set out possible concepts of how gene expression may be controlled as to relate the facts which we have so far gathered. Where paradoxes exist which cannot yet be reconciled, I have tried to give a balanced account of ways to view them. The book is clearly organized. The treatment is of course to some extent selective, yet the bibliography covers 40 pages of close print. The table of contents speaks for itself; suffice it to add that ch.7 (which is of most direct interest to developmental biologists) has sections on nuclear transplantation (1 1 pp.), somatic cell hybridization (14 pp.), and the genetic complement of hybrid cells (16 pp.). The illustrations include many original diagrams as well as numerous good light and electron micrographs. In the bibliography the large majority of titles are less than 10 years old, and many date from 1973. (The lay-out of the bibliography lacks clarity; the subject index is less than adequate.) 230 Textbooks 108. C. L. MARKERT and H. URSPRUNG. 1974. ENTWICKLUNGSBIOLOGISCHE GENE- TIK Fischer, Stuttgart.

It is meant for advanced students with a good background in molecular biology, since the emphasis is on differential gene action in development. It was reviewed in Gen. Embryol. Inf. Serv., suppl. to vol. 14, p. 42. The second author has translated the book and has taken the opportunity to update and extend it slightly. However, the basic set-up has remained the same. The main improvements are the correction and extension of various figure legends, and the extension of most chapter bibliographies to two or three times their original length. The number of figures has remained the same, though two figures were replaced. The subject index was extended. Symposium reports 109. F. H. RUDDLE, ed. 1973.

It was held in June, 1972. The 13 reviews are all highly informative and clearly set out. It was a good idea to include reviews on genetic control in bacteriophage lambda and T4 development and in sporulating bacteria. Also of interest is a chapter on cell genetics of higher plants. The volume is concluded by a summary of a panel session on social aspects of genetic engineering, consisting of brief statements by four scientists and a theologian. The remainder of the contents can be briefly characterized by enumerating the systems dealt with: Drosophila sperm, the Drosophila embryo, Drosophila mosaics (mapping of behaviour), the Mexican axolotl, the early mammalian embryo, the chick oviduct (ovalbumin regulation), the Xenopus genome, and cell heterokaryons and hy- brids. The book is produced with the usual exemplary care. DEVELOPMENTAL PHYSIOLOGY (incl. endocrinology, immunology, behaviour, etc.) (see also 37,47,49,63,64,66,82,98,104) Treatises 110. J. B.

These are to be found particularly in Part Two, which is entitled Placental structure and protein hormone secretion, and fetal nutrition. It begins with a review by Laga et al. in which major sections are concerned with the quantitative structure and composition of human placentas and its relationship to placental function. 231 Then follow chapters on the relation of chorionic gonadotropin and somatomammotropin to maternal and fetal nutrition, by Kaplan and Grumbach, Emerson et al, and Crosignani. In Part Three (The mammary gland and the control of lactation) three chapters seem to be of interest to our readers: Morphologic changes of the mammary gland during development, pregnancy and lactation (by Salazar and Tobon); Hormonal control of cellular events during lactogenesis (by Rivera, who treats lactation as a developmental process); and Placental peptide hormones affecting fetal nutrition and lactation (by Matthies', who also describes the putative role of these hormones in the maintenance of gestation). Part One is entitled CJiemical and biologic characterization of pituitary and placental lactogenic hormones, and consists of eight chapters. The book is well produced and contains excellent light and electron micrographs. Textbooks 111. V. WIGGLESWORTH. 1974. INSECT HORMONES Oxford Univ. Press, London.

It describes the major events of embryonic development which result in a viable hatchling, and the underlying mechanisms. Part one covers 120, and part two 150 pages. The earliest stages considered are early somite stages, and the treatment extends into the early neonatal period. The list of avian species referred to in one or more places in the text comprises more than 80 names. There are two extremely useful appendixes. The first is an 8-page tabular chronological survey of development in the domestic fowl, harmonized with Hamilton/Hamburger 232 stages. The second appendix is an excellent photographic atlas of the chick embryo in relation to the shell, yolk, albumen, and membranes at intervals of one day. The book is well produced and profusely illustrated. It has a number of good photographic plates apart from those in appendix 2. The bibliography comprises ca. 1 .000 titles, is up to date until late 1973, and contains many titles in languages other than Engfish. 114. G. K. ROUSSEV. 1974. PROGRAMME OF EMBRYONIC DEVELOPMENT DIRECTED BY ONTOGENINES (in Bulgarian) Publ. House Naouka i Izkoustvo, Sofia. 298 pp., 21 figs., 18 pis., 20 tabs. English sum- mary (12 pp.) The author of this book has worked with aqueous extracts of early amphibian embryos since 1954. He claims to have isolated no less than 247 different "ontogenines" from embryos ranging from the fertilized egg to the tailbud stage. Their effects can be tested by simply introducing them into the culture solution of other embryos. There are four classes of effect: general inhibiting, general promoting, stage-specific inhibiting, and stage-specific promoting. During development the ontogenines appear and disappear during specific periods of the order of minutes to hours. Preliminary biochemical analysis suggests that low-molecu- lar ontogenines may be peptides or nucleotidylpeptidates, and some of the high-molecular ones DNP-RNP-glycoprotein complexes. Ontogenines seem to have effects on translation and transcription and even on the structure of DNA. Their activity seems to require binding to specific cell fractions and they can pass between cells. There is much more in this book than can be related here. Although it is difficult to judge the quality of the work from the English summary, the approach certainly is a novel one and a translation of the book would seem to be justified.

DM 55.70, $ 21.50 Although nowhere stated, this book is apparently based on a symposium held some time during 1971. Many of the papers are therefore out of date. We mainly review it here because it contains a series of brief reviews on insect endocrinology that may be of some use to those working on morphogenetic hormones. Most of the reviews in question are to be found in the section Hormonal control of metamorphosis in part I of the book. There is an interesting introduction by Wiggles- worth, and papers by Judy, Kobayashi, Karlson, Sekeris, Thomson, and Burdette (the latter containing original results on the action of viruses on polytene chromosomes). The other sections of part I deal with hormone assays and with biosynthesis and degradation of insect hormones. Part II contains three papers by Japanese workers on ecdysones. Part III deals with hormones and protein synthesis in mammals (and is strangely out of place), while part IV discusses Hormonal heterophylly - an ill-considered word for the action of hormones from one phylum (arthropods) on the tissues of another (vertebrates). 233 116.

Despite its "clinical" title, the book contains recent information that may be of great value to embryologists. This is to be found in roughly the first half of the book, that is, in the sections entitled Differentiation, Drug effects in tissue and organ culture, and The placenta (10 papers in all). The second half of the book is more clinically oriented. The emphasis, however, is on fundamental mechanisms. All contributors are distinguished specialists. Each paper is a concentrated review of recent research. The organs that receive most attention are the central nervous system (Timiras, Vernadakis), the hver (Greengard, Nebert, Hahn), and the intestinal epithelium (Balis). The two papers on the placenta of most interest to our readers are by Juchau and Dancis. Each paper is followed by a group discussion. The book is very well produced. 117. M. G. FOREST and J.

Its participants were specialists from various Western European countries and from North America and Israel. The papers are in French or English but all have summaries in the other language. Almost all of the 15 papers in the first two sections are of interest to mammalian embryologists. Section I deals with endocrine functional morphology, section II with biosynthesis, metabolism and regulation of sexual steroids and gonadotropins during the perinatal period in various mammals including sheep and monkey. Section III is on the same subject studied clinically in man, while section IV examines the postnatal conse- quences of perinatal hormone changes. The papers are reproduced by photo-offset from typescripts. Photographical illustra- tions are printed on glossy paper. 118. P. LIACOPOULOS and J. PANIJEL, organizers. 1973.

F.fr. 50.00 (paper) This international symposium was held in Paris in October, 1972. Of the 47 partici- pants, 21 came from a variety of countries outside France. The 31 contributions are mostly brief research reports. Many are of course in French, but most (though not all) of these have English summaries. At least half of the papers are of interest to developmental biologists. The papers are arranged in four sections as follows: Phylogenesis in invertebrates (6 papers); Phylogenesis in lower vertebrates (10); Ontogenesis (10, in amphibians, birds, and mammals); Ontogene.'^is in man (5). The volume was produced by photo-offset straight from the typescripts as they came in. Photographic illustrations aic printed on glossy paper. 234 119. A. R. LIBOFF and R. A. RINALDI, eds. 1974.

This symposium was purportedly the first ever to bring together scientists of widely varying speciaUzations (physicists, chemists, biologists, and physicians) to discuss their common interests, or at least to discover whether they have a common language to speak in. The contents of the volume are so varied that it is impossible to review it in detail. However, anyone who takes an interest in this subject is sure to find something of interest in it. The participants were mostly North American, but there is a fair sprinkling of contributors from other continents. There are 46 short to medium-length papers, which are arranged in three sections as follows: Physical and chemical studies (16 papers); Biological studies (18); and Clinical studies (12). In section I the main emphasis is on the properties of hard tissues. In section II the attention turns largely to cellular and supracellular aspects. This section contains at least half a dozen papers that are of direct relevance to developmental biology (to mention some authors: R. O. Becker, Harrington, L. Weiss, Jaffe, Brick, Woodruff, Katz- berg). The last section deals largely with bone growth, bone and cartilage fracture healing, and vertebrate Umb and tissue regeneration. Most papers are followed by brief group discussions, and there are longer panel discussions at the end of each section. The volume is profusely illustrated. It has no indexes. 120. G. RASPE and S.

DM45.00 This symposium brought together 13 scientists of various specializations to discuss a number of open questions in this area from embryological, endocrinological, and pharma- cological viewpoints. Eight of the participants came from West Germany. Some of the contributions are research reports but most are reviews of recent work by the authors and others. The discussions are not recorded. Most of the contributions deal with sexual development (including behaviour) and with the state of pregnancy in mammals including man. One deals with indirect and direct actions of ovarian hormones on the blastocyst. Four contributions are by the Schering group for endocrine pharmacology (Neumann, Elger, and others).
