Faber, Deputy Director of the Hubrecht Labotory Managing Editor: B. Z. Salome Hubrecht Laboratory Uppsalalaan 1 Universiteitscentrum "De Uithof" UTRECHT, Netherlands Printed in the Netherlands, 1974 CONTENTS Introduction 5 Directory of Names and Addresses, with subjects of research (alphabetical order) ... 7 Directory of Institutes, with members engaged in developmental biology. Europe . . 107 Subject Index (alphabetical order) 126 International Organizations and Facilities 174 Book notices 179 INTRODUCTION In the Introduction to vol. 14 we omitted to mention that Dr. P. D. Nieuwkoop had resigned as editor-in-chief, although the fact was clear from the colophon. In 1949, two years after he first became associated with the Hubrecht Laboratory, Dr. Nieuwkoop took the initiative to establish an Information Service for developmental biologists throughout the world, and he produced the first few issues almost single-handed. These issues to a large extent determined the format and content of the periodical in subsequent years. Gradually J. Faber took over more and more of the work, since 1969 with the assistance of B. Z. Salome. Although Dr. Nieuwkoop is now no longer an editor he continues to be a member of the Board of the G.E.I.S. Foundation. During the past years the editors have been increasingly faced with financial and organizational problems. In an attempt to solve these they have decided to effect the following changes: (1) In order to reduce the cost of production the periodical is now printed in photo-offset in a simplified format. Although special type such as italics, bold face and small capitals can be used only exceptionally, we are trying to maintain maximal clarity. (2) In order to achieve a more efficient distribution of editorial and secretarial work over the two-year period, each volume is now published in two parts of more or less equal size. Part 1 (odd years) covers ca. 24 countries in Europe, while part 2 (even years) covers the remaining geographical areas (ca. 23 countries). Each part has its own geographical directory and subject index, and each contains a substantial number of book notices. The Supplement has ceased to exist. A poll was held among the subscribers in 1972. Eighty subscribers (ca. 2090 replied to the questionnaire. It appeared that the subject index was being consulted with reasonable to high frequency, and that the format of the index prevailing until 1971 was considered satisfactory to good. Although several correspondents felt some objection to a change in format, most were prepared to put up with the proposed simplification. This has therefore been carried through starting with the present volume. The book notices were judged to be useful to very useful. Several correspondents made suggestions for improvement, but these were too diverse in nature to provide a guideline for meaningful changes. As a result of a campaign held in 1972 the number of subscribers shov> ed an increase, albeit rather slight. Our financial position is in continuous jeopardy because a small but significant proportion of the subscribers pay their dues too late or not at all. This has forced us to change to a pre-pay system. We apply to subscribers to help us maintain a sound financial basis. (This appeal is not directed to those who have always paid regularly!) J. Faber B. Z. Salome DIRECTORY OF NAMES AND ADDRESSES with Subjects of Research (alphabetical order) Unless stated otherwise, information in this directory is based upon data sheets which were sent to the institutes listed in the Directory of Institutes, and returned to the editors before October 1973. Scientists were asked to state their name, degree(s), address, and research subjects in so far as recent, unpublished work in developmental biology was concerned. Complete entries (with research subjects) are entirely based on the data sheets. Subjects identical to those in vol. 14 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. 14 who have not returned their sheets. Names degrees, and addresses were reprinted unchanged from vol. 14 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. 14 whose death has come to our attention (marked t)- Persons listed in vol. 14 but not in vol. 15 a. Persons who had research subjects in vol. 14 but are no longer engaged in research in developmental biology. b. Persons who had no research subjects in vol. 14 and have not returned the sheets for both vol. 14 and 15. Names of members of the International Society of Developmental Biologists are marked ISDB.

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 1973. 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. * KIERMAYER, O.

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. The list of headings has not changed much. 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. Most of the common techniques that figured as headings in the index of vol. 14 are now omitted, they will be found as subheadings (see below). Techniques still appearing as headings are: Chemical microanalysis, Culture, Immuno- chemistry, Irradiation, Rearing methods, Transplantation, UV Irradiation, Vital staining, X-Irradiation. 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 take the place of the former entries. Headings having less than ca. 10 names of investigators usually lack subheadings. The same research subject may be listed more than once under the same heading, e.g. under a structure and a technique. Subheadings come under one of the following categories: 1) Entities subordinate to the heading 2) Entities related to the subject of the heading 3) Techniques, disciplines, 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 . . ., interaction with . . .". Animal and Plant Names All the work on multicellular plants and on slime moulds is brought together under one heading: Plant embryology & 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. 126 New Headings Cell fusion

Partial financial support is available in special cases 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. Recent additions are the collection of the late J. P. Hill and that of H. Griineberg. Details will be supplied on request. b) The Central Embryological Library, an extensive reprint collection covering the entire field of developmental biology, with documentation and bibliographical services attached to it. Details will be supplied 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 will probably be held in the first six months of 1976. In that case, circulars will be widely distributed in the fall of 1974, and will also be sent on request. 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 (VIHth Congress to be held in 1977), as well as one or two regional Symposia every year. Members receive a Developmental Biology Newsletter. International Secretary: Dr. R. L. DeHaan, Department of Anatomy, Emory University, School of Basic Health Sciences, Atlanta Ga. 30322, U.S.A. Secretary-Treasurer: Dr. J. J. Wartiovaara, Lab. of Exper. Embryol., Ill Dept. of Pathol., Univ. of Helsinki, Haart- maninkatu 3, 00290 Helsinki 29, Finland. Membership over 500. Membership list follows below. 174 Membership List of the International Society of Developmental Biologists (alphabetical order, with years of election,* emeritus members) This list was drawn up on March 1st, 1974. For full addresses of European members see General Embryological Information Service vol. 15, pt. 1 (a few names are lacking or not marked ISDB due to the earlier date at which the Directory was drawn up). Full addresses of members from countries outside Europe will appear in vol. 15, pt. 2. Miss U. Abbott, Washington, D.C'64 M. Abercrombic, Cambridge,'56 H. B. Adelmann*, Ithaca, N.Y.'48 I. P. S.

Summary: Basic guidelines and principles of development This textbook which is clearly meant for the use of advanced students, is one of several recent attempts to present develop- mental biology as a unified whole. Throughout the book data on plants, animals, and protozoa are treated alongside, and almost every developmental process of any importance is dealt with. The unifying theme is that of "guidelines of development" at all levels from the molecular to the organismal. On the whole the arrangement of chapters is logical, although one could argue with the author on the desirability of treating postembryonic development and regeneration at such an early stage (chs.4 and 5), and of including the emergence of order and pattern formation (chs.25 and 26) under special aspects rather than under universal control mechanisms. The present re- viewer feels more serious objections against the author's style which frequently lacks didactic clarity. Important concepts are often insufficiently or not at all defined. Although the treat- ment is certainly not superficial, in many places the writing is bound to be confusing to the student. In several areas with which the reviewer is more intimately familiar he was struck by major and minor inaccuracies and instances of partial misinter- pretation of data. In short, the text is worth while in general outline but capable of considerable improvement. The same judgement applies to many, though not the majority of the illustrations. All figures were especially prepared for this book, and most are artistically successful; however, not a few are confusing in their lay-out, lettering and "arrowing", and some are partially incorrect; several captions do not ex- actly match the figures. The chapter bibliographies are well selected and strike a good balance between older and more re- cent literature (there are rather too many mistakes in the spelling of foreign authors' names). The subject index is not entirely adequate. The book is beautifully produced on a pleas- ing format . 2. J.R.TATA. 1973. METAMORPHOSIS Oxford Univ.

(paper) This is a competent and up-to-date survey of carefully chosen examples from a wide field where it is difficult to be selec- tive. The author does not always achieve maximal lucidity: ex- amples are the role of the median eminence in the frog and the feed-back arrows in fig. 7. Fig. 10c could be improved. The other illustrations serve their purpose well. 182 THEORETICAL AND MATHEMATICAL DEVELOPMENTAL BIOLOGY Treatises 3. R.ROSEN, ed. 1972. FOUNDATIONS OF MATHEMATICAL BIOLOGY. Vol.11 Cellular systems Academic Press, New York, etc. XVIII, 330 pp., 116 figs., 3 tabs. author and subject indexes. $ 16.00 This is the second volume of a three-volume series, the other two being entitled "Subcellular Systems" and "Supercellular Systems". The book consists of five chapters, and with possibly one exception, is not of much use to people working on problems of development. The exception is Arbib's essay on automata theory. To put it simply, the approach is to regard the cell as a spatially dis- crete unit which has access to a number of states under the in- fluence of its neighbours. The contrast with the usual conti- nuum models employed by theorists is obvious. It is very inter- esting, for instance, to see how the problem of the regulation of pattern in multicellular systems is posed. Readers without a background in mathematics (especially formal logic) can safely skip sections 4 and 5 and still get the flavour of the attempt. In particular, no one should miss the evaluation on page 208 of Wigner's old (wrong) claim that the laws of physics make it highly unlikely that self-reproducing beings can exist. Rescigno and Beck contribute a chapter on compartment analy- sis. As the word might suggest, this is a study of the dynamics of exchange of substances between different units (composed of cells). A typical problem - mentioned by the authors - is the distribution (at different times) of radioactivity in the blood, the lipid of the liver, and the skeleton of rats fed radioac- tive phosphate. The remaining chapters are all by Rosen. "Morphogenesis" con- siders strategies for assembling a whole out of a large number of subunits, allowing for errors. A survey of theories of cell sorting-out follows; readers must remember that the problem is posed as one static in time, and is essentially restricted to minimizing the configuration energy. Then there is a summary of the attempts of Turing, and of Keller and Segel to look at mor- phogenesis (in particular, the formation of spatial pattern) as a phenomenon in which a system "switches" from one steady state to another when external parameters are suitably varied. On page 58, a misleading aside on entropy and order intervenes; this is best totally disregarded. "Mechanics of epigenetic con- trol" yields quite a few misprints even on first sight; and more dangerously, wrong mathematics right at the beginning, in the study on open systems with chemical kinetics (page 87). And there is a reference to a non-existent figure 2a which is sup- posed to show a stable point in phase space, whereas both fig- ures 2 show instabilities However, the varieties of chem- ical kinetics considered can make this chapter useful as a source of ideas, if one is careful not to take the results on faith. "Metabolism-repair systems" is a super-formalised ac- count of input-output systems representing cells, and might suit the reader who demands no biology in her mathematics. On the whole, this is a book quite dispensable to developmen- tal biologists. V.Nanjundiah 183 Monographs 4. J.S.HUXLEY. 1972. PROBLEMS OF RELATIVE GROWTH. 2nd edit. Dover Publications, New York.

Des catastrophes aux archetypes: pensee et langage A critical review of this remarkable book could only be writ- ten by a mathematician of equal distinction as the author, who would also have to know a lot about biology. It is clear, there- fore, that we can do no more than highlight some of its major features . The author is a distinguished mathematician whose main in- terest is in problems of form (or geometry) as they are encoun- tered in biology, linguistics, psychology, etc. He is a con- firmed anti-reductionist and a proponent of qualitative versus quantitative thinking, and for this reason alone is bound to meet with opposition from many contemporary scientists. He points out, however, that rigorous qualitative thinking has been made possible by the recent progress in differential cal- culus and topology. The type of dynamic model he proposes in the book has its phase space defined by means of the values of "observable" ("macroscopic") parameters, without reference to the infinitely complex underlying structures. Once we accept the validity of this approach the results are surprising and illuminating. In his foreword the author states that the book provides a mathematical substructure for d'Arcy Thompson's "On Growth and Form". He adds that Waddington's notions of "epigenetic land- scape" and "chreod" have been essential germinal points for this theory. Other inspiring authors were von Uexkull and Gold- stein. In his English preface to the book Waddington gives the following characteristic: Thorn has tried to show, in detail and with precision, just how the global regularities with which biology deals can be envisaged as structures within a many-dimensioned space. He has not only shown how such ideas as chreods, the epigenetic 184 landscape, switching points, etc., - which previously were expressed only in the unsophisticated language of biology -, can be formulated more adequately in terms such as vector fields, attractors, catastrophies and the like; going much further than this, he develops many highly original ideas, both strictly mathematical ones within the field of topology, and applications of these to very many aspects of biology and of other sciences. Thorn takes the standpoint (chapter 8) that geometrical or field phenomena are a reality throughout living nature which is brought to light by topology, and that we can describe such phe- nomena and determine their formal properties and developmental laws without asking, for the time being, what is their ultimate nature (much as physicists use the gravitational laws with suc- cess without yet having the remotest idea what gravity is). Such a standpoint, if proved valid, would of course also have far-reaching philosophical implications. As to the actual content of the book, we will restrict our- selves to a few remarks. In chapter 9 the author applies his topological concepts to gastrulation in amphibians, to the com- parative gastrulation of vertebrates, to neurulation and dorsal axis formation, to induction and individuation, and to some problems of late morphogenesis. He comes up with topological models for most of these processes which, he admits, are still very speculative and subject to verification. In chapter 10 he describes three classes of models for global organization of metazoan organisms (static, metabolic, and hydraulic) and dis- cusses organogenesis and cellular differentiation. In chapter 12 he successively discusses finality, the irreversibility of differentiation, the origin of life, and evolution. In the reviewer's opinion (which is admittedly largely intu- itive, due to a lack of suitable mathematical training) this rich and important book may well on the long run initiate a major revolution in biological thinking generally and in the approach to morphogenesis in particular. 6. G.D.WASSERMANN. 1972. MOLECULAR CONTROL OF CELL DIFFERENTIATION AND MORPHOGENESIS, a systematic theory Marcel Dekker, New York. Quantitative Approach to Life Science Vol.2. XVI, 582 pp., 5^ figs., 4 tabs., author and subject in- dexes. $ 36.50, £ 17.35 The author of this intriguing monograph is a physicist with a thorough knowledge of molecular biology and biophysics. The book is concerned with the basic and topical question whether cell differentiation and morphogenesis can be explained entire- ly on the basis of the specific properties of individual cells as determined by their biochemical activities, or whether it is necessary to invoke less specific global or supracellular prin- ciples (e.g. fields or gradients). The author is a confirmed proponent of the former view, and here presents a theory which is intended to bridge the gap between genetics and embryology directly via molecular biology. The theory is best characterized as a molecular automaton theory. Because of its extreme complex- ity it is impossible to give a complete review here; instead, we restrict ourselves to highlighting some of its salient features. The book is entirely hypothetical in character, and the author concedes that this theory is supported by indirect evidence only. The central chapters of the book will make tough reading for most, 185 but large parts of it can be read without going deeply into the mathematical procedures used. The author very usefully suggests several shortened "reading routes" for various categories of readers . The theory is based in large part on a generalization of Sperry's "chemical neurospecif icity" hypothesis, in conjunction with Weiss' "molecular ecology" concept. The underlying tenet is that each individual somatic cell in a metazoan organism (with certain exceptions) is chemically uniquely specified, and that this specification is under genetic control from the begin- ning of development in a completely specific, non-random manner. The specification is postulated to be due to "cell-unique pro- teins", and is called "microdif ferentiation" (this concept ex- cludes all types of morphological and chemical differentiation hitherto distinguished, which are all brought under the heading of "gross differentiation"). On the basis of a sophisticated model for the structure of eukaryotic chromosomes and for the transcription process the author argues that the organism con- tains more than enough DNA to specify 10 chemically distinct cells (on the auxiliary hypothesis that the one-cistron - one- polypeptide rule does not hold for cell-unique proteins). On this foundation a huge theoretical superstructure is then erected, which makes use of a multitude of newly coined terms and concepts, and encompasses no less than 36 "fundamental hy- potheses". A central part of the theory is a basically simple, but very elaborate "process algorithm" for the explanation of microdifferentiation. This is based on the notion of a "devel- opmental tree" (with numerous "sub-trees"), a cell genealogy defined by the use of enumeration techniques. Among other things, the theory envisages asymmetrical mitoses which ensure that the derepressed state of a particular gene is passed on to one of two daughter cells and its descendents. At certain times hypothetical "inductive stimulus substances" of relatively low specificity, produced by cells other than the generator cell of a sub-tree, trigger off further development of the sub-tree in question. The cytoplasm is assumed to play no role whatsoever in the selective derepression of the genes concerned in microdifferentiation (in contrast to those in- volved in gross differentiation, but here the controlling cy- toplasmic constituents would again be cell-unique proteins). The cell-unique proteins are postulated to serve as compo- nents of two basic types of structure: "protein chains" and "molecular maps". The former are predominantly intracellular and, among other things, can specify intracellular axes (e.g. the polar axis of the egg). The latter are assumed to consti- tute the bounding layers of triple membranes, located both in- ternally and at the cell periphery; in the latter position they are responsible (in conjunction with "protuding protein chains" attached to them) for cell recognition, cell matching, cell contacts, and even morphogenetic movements (for which a number of auxiliary hypotheses are introduced). All these processes are thus ultimately under strict genetic control. Apart from this rigid, genome-centered control system, which is basically a switching system, the theory also embodies con- tinuous variables which are required to explain the flexibili- ty of development (e.g. regulation, regeneration). Among these are the concentrations of cell-unique proteins, and the concen- trations of "stabilizer substances"; the latter are less spe- cific diffusible factors which, if present in amounts exceeding critical thresholds, can stabilize the derepressed states of genes. The author disagrees with those who invoke gradients 186 (particularly those based on diffusion) as primary causative agents in morphogenesis. He postulates that the synthesis of the diffusible factors which play a role in his theory ("in- ductive stimulus" and "stabilizer" substances) again depends indirectly on the presence of cell-unique proteins, which them- selves are under strict genetic control in the way suggested earlier . The author is of course aware of the fact that Sperry's "chemical neurospecif icity" hypothesis is currently under at- tack, notably by Gaze. He claims, however, that on the basis of his theory a reconciliation of the views of Sperry (and partly of Weiss) with those of Gaze is possible. He rejects Weiss' modulation hypothesis and proposes instead a "principle of al- ternative matching" between chemically uniquely specified cells, which distinguishes between optimal and suboptimal matching of cell surfaces. The theory bears a pronounced unitarian stamp and encompasses several biological problems falling outside embryology in the strict sense, such as antibody formation, connectivity in the nervous system, and cell contacts generally. The embryological areas of application are reaggregation and cell sorting, morpho- genetic movements, establishment of embryonic axes, and devel- opmental stability and regulation. With respect to cell con- tacts the author extensively discusses the views of Curtis, with whom he disagrees to the point of becoming polemical. The latter two subjects are discussed on the basis of a few select- ed examples, mainly taken from the work of Driesch, Roux, and HSrstadius. The important problems of pattern formation and pattern regulation are treated only in the most general manner, without suggesting detailed mechanisms. This is definitely a weak point in the whole theory. The theory certainly is novel and ingenious, and involves the reversal of several traditionally accepted views. On these ac- counts alone, at least its basic assumptions deserve the atten- tion of developmental biologists, if only to stimulate further discussion of these important problems. Only the future can show to what extent the theory is valid as it stands, but it may be a long time before it can be critically tested by ex- periment . 7. A.I.ZOTIN. 1972.

Constitutive approach of the living systems to the final stationary state; IV. Constitutive deviation of living systems from the steady state; V. A pos- sible molecular mechanism of the constitutive processes; VI. Thermodynamic theory of growth This interesting monograph is devoted to an elaboration of the ideas of Prigogine and Wiame, who in 19^6 suggested that the main equations and concepts of the thermodynamics of irrevers- ible processes might be applicable to animal growth and develop- ment. The author is head of the Laboratory of Biophysics, Insti- tute of Developmental Biology, Academy of Sciences of the USSR. He and his colleagues have published a considerable amount of experimental and theoretical work on the metabolism and ener- 187 getics of various phases of vertebrate development. For the il- lustration of his ideas the author preferentially uses examples from this work; he also extensively covers the Russian theoret- ical work in this area. The emphasis in the treatment lies on the "growth" aspects of development. Interactions between growth and differentiation are only considered in the penultimate section of the last chapter. The main tenet of the book is that development and ageing can be equated to a continuous ("constitutive") decrease of the energy dissipation function, and consequently of the specific rate of entropy production. Conversely, oogenesis, re- generation, and malignant growth would all represent "rejuvena- tion", involving an increase of the dissipation function at the expense of coupled processes in other parts of the system. Proper attention is devoted to the definition of such concepts as "steady state" and "stationary state", in connection with homeostasis and homeorhesis. These ideas are adstructed with numerous experimental data in chs.III through V. Ch.VI discusses several old and modern types of growth equations from the view- _ point of thermodynamics. The book is written in English that is perfectly readable though not idiomatic. There are rather many printing errors. The bibliography has about 500 titles. There are no indexes. The book is rather expensive. Symposium reports 8. J. D. COWAN, ed. 1972. SOME MATHEMATICAL QUESTIONS IN BIOLOGY. Ill Am, Mathemat. Soc, Providence. Lectures on Mathematics in the Life Sciences. Vol.4. VI, 151 pp., 28 figs., author and subject indexes These lectures were delivered at a Symposium held in Chicago in December, 1970. We will only consider the three papers that have a bearing on developmental biology. The two papers by L.A. Segel and by A.Robertson deal with slime molds (the former also partly with bacteria) and are partly simplified presentations of published material, though the second paper contains prelim- inary experimental data that were new at the time of writing. Segel and Robertson deal with their subject from quite dif- ferent viewpoints. Segel formulates models for the initiation of aggregation in homogeneously distributed populations of amoebae, and his approach is based on random perturbations and is related to the earlier work of Turing. Robertson essentially deals with the whole slime mold life cycle and his starting point is the periodic secretion of cyclic AMP. He presents no new models but clearly favours the phase-shift model of Goodwin and Cohen for the interpretation of his findings. Incidentally, both papers contain interesting remarks on some conditions un- der which mathematics can be useful for biology. B.C. Goodwin takes his starting point in experimental results of R.M.Gaze on the retino-tectal projection in amphibians. He subjects these to a qualitative analysis in terms of two dif- ferent models, a double-gradient model and Goodwin and Cohen's phase-shift model, and uses the results to tentatively discrim- inate between the two types of model for this particular system. 9.

VI, 150 pp., 76 figs., 7 tabs., author and subject indexes The Symposium on which this book is based was held in Phila- delphia in December, 1971. The only lecture which is of direct significance to developmental biologists is that by R. Thorn en- titled "A global dynamical scheme for vertebrate embryology". Although the paper is very condensed (it covers only 43 small pages) and presupposes considerable mathematical knowledge, it may be useful as a first introduction into Thorn's thinking, particularly for those to whom his recent book (see review nr. 5) is inaccessible for linguistic reasons. In fact, the article is in part a further elaboration of that portion of the book that deals with embryos. Thorn starts from the topological theory of "catastrophes", i.e. of those characteristic discontinuities which arise in the solutions of systems of differential equations with macroscopic parameters. He then applies this theory to the following pheno- mena: amphibian and avian gastrulation and their homology, bi- lateral symmetry in the mesoderm, notochord formation, forma- tion of the axial system, closure of the neural tube, and heart formation. In his concluding remarks the author anticipates the objection that he uses finalistic reasoning as follows: "even if you allow yourself all the facilities of teleological think- ing, you are still very far from explaining development. For embryology is full of enigmatic structures, of transient mor- phologies, which do not seem to have the slightest biological usefulness. Catastrophe theory may help in interpreting these structures, as it describes the basic and universal constraints of stability imposed on epigenetic mechanisms". 10. C.H.WADDINGTON, ed. 1972.

VI, 299 pp., 74 figs., 3 tabs., author and subject indexes. £ 5-50 Participants: Arbib, Conrad, Cowan, Elsdale, Fowler, Goodwin, Kauffman, Pattee, Thorn, Waddington, Wolpert, Zeeman This is the last of a series of volumes emerging from the IUBS Symposia held in Bellagio, Italy in the years 1966 through 1969. The first three volumes were reviewed in Gen. Embryol. Inf. Serv., Suppl.l_3, 1970, p. 12/13. The present volume contains 13 essays partly based on, and partly grown from the presenta- tions given at the Symposium. The volume has more unity than the preceding ones, both as to style and content. In an epilogue Waddington presents his per- sonal interpretation of the particular types of question and frameworks of thought that seemed to emerge towards the end of the series of Symposia. The focal point is the confrontation of microstates and macrostates of biological systems, and more par- ticularly "the ways of handling simple macrostates without having to break them down into an unmanageable plethora of vast- ly complex microstates". Waddington points out that the "struc- tures mediating global simplicity" may perhaps be clarified with the help of the analogy of language, a procedure which is prom- inent in several of the contributions. Most of the contributions deal either with morphogenesis or 189 with the operations of the nervous system. The following contri- butions seem to be of particular significance to developmental biologists: Thorn on structuralism and biology; Wolpert on posi- tional information; Elsdale on inherently precise morphogenetic processes in fibroblast cultures; Waddington on form and infor- mation (with brief comments by Thorn and Wolpert); and Arbib on organizational principles for theoretical neurophysiology.

All of them are well organized and have extensive bibli- ographies . The chapters in question are that on the development of gymno- sperm seeds by Singh and Johri (55 PP«)» that on the development of angiosperm seeds by Bhatnagar and Johri (72 pp.), and that on seed germination and morphogenesis by Berlyn (90 pp.). In all three the emphasis is on morphology and cytology, but histochem- ical aspects are also considered. Seed development is broadly defined, starting with the pre-pollination ovule and including the fertilization process. Most of the chapter by Berlyn is taken up by a detailed description of germination in Zea and Pinus, in which much attention is given to the establishment of the primary plant body with its shoot and root apices. The three chapters are profusely illustrated, the first two mainly with excellent line drawings, the third also with photo- micrographs and electron micrographs. The bibliographies are up to date until 1969/70. Vol.11 contains, among other things, chapters on the environmental control of germination and on the metabolism of germinating seeds. Textbooks 12. F.

Selected classical and modern findings are synthesized with didactic clarity. The treatment starts at the 190 molecular level and advances through subcellular units, cells and tissues to the whole plant. The first section covers about one third of the book and considers enzymes, cell membranes, the major plant hormones, other chemical messengers, and environmen- tal factors. The next longest section is that devoted to the whole plant. All major aspects are duly considered, except re- generation from single cells. The treatment is restricted mainly to higher plants. The figures are judiciously selected and are provided with lengthy captions, making them more or less independent from the text. At the end of the book there is a good eight-page classi- fied bibliography for further reading, consisting of books and review articles in English and German. T.A.STEEVES and I.M.SUSSEX. 1972.

The cellular basis of organization This book is the companion volume of a book in the same series, entitled Control mechanisms in plant development (Galston and Davies, 1970, reviewed in Gen. Embryol. Inf. Serv. vol. 14, 1971). This enabled the authors of the present book to adhere strictly to a structural viewpoint. As a result, they could go much more deeply into problems of structural organization than is custom- ary in introductory texts. This makes their book particularly interesting for non-botanists, because it is in this area that the most striking parallels between plant and animal development are found. The authors use the organismal approach throughout, with em- phasis on experimental morphology rather than physiology or bio- chemistry. Their style is lucid and captivating, and they use considerable common sense in pointing out the dangers of over- simplification and theorizing. Numerous areas where more know- ledge is urgently needed are indicated. The treatment is restrict' ed to the vascular plants, but within this group many different types of organization are considered. All chapters are concluded by a thoughtful comment and a se- lective reference list through which the student is brought in- to contact with the germinal literature, both older and recent. The book is very well produced and profusely illustrated with good line drawings and photographs provided with explanatory captions. The price is very reasonable. 191 Monographs W.A.JENSEN. 1972.

It is based primarily on original research carried out for over a decade on one particular object, the leaf of Xanthium, and its most interesting feature is that it combines morphological, cellular, and metabolic approaches, all rigorous- ly quantitative in nature. Throughout the book an indirect time- scale of development is used, the plastochron index originally developed by Erickson and Michelini. The book is in two parts, each consisting of 12 brief chapters. The first part deals with morphological patterns, the second with physiological aspects. Some of the topics considered in part 1 are leaf initiation, cell lineage in the marginal and plate meristems, cell division, enlargement, and differentiation, and the correlation of these processes. Part two considers, among other things, DNA synthesis (thymidine incorporation), chlorophyll synthesis, respiration, enzyme synthesis, and the role of plant hormones in leaf development. The book is very well produced and illustrated. Other volumes of the series are anticipated with interest. 17. H.MOHR. 1972. LECTURES ON PHOTOMORPHOGENESIS Springer, Berlin, etc. XII, 237 pp., 219 figs., 22 tabs., subject index. DM 46.60, $ 14.80, £ 7.50 The term photomorphogenesis covers much more than the develop- ment of form under the influence of light: it includes phenomena at all levels of analysis. In plants the phytochrome concept is central to photomorphogenesis, but a really comprehensive and up to date account of this concept was not available. The present book admirably fills this gap. It is based on a series of 24 lectures given by the author in 1971 at the University of Massa- chusetts; the format of lectures has been retained in the book. The emphasis is on developmental physiology and on the signifi- cance of phytochrome research within the area of general molecu- lar biology; historical aspects were omitted unless essential. Every conceivable aspect of phytochrome research is duly con- sidered, with emphasis on the organism used by the author and his associates: the mustard seedling. The subject is discussed with great authority and didactic clarity against a broad bio- logical background, and the book contains much that is of inter- est to developmental biologists generally. To mention a few ex- amples: phytochrome-mediated enzyme induction and repression, and modulation of metabolic steady states; interactions with 192 plant hormones; RNA/protein synthesis and cell stretching; threshold mechanisms of various kinds; primary and secondary differentiation (i.e., competence for hormone action, and bio- chemical differentiation, respectively); flavonoid synthesis as a model for biochemical differentiation; energetics of morpho- genesis (thermodynamical considerations); blue-light-mediated photomorphogenesis; and general considerations of genes and the environment . The book is well printed and very well illustrated. It has a bibliography of over 300 titles, and in addition each lecture is concluded by a brief list of suggested further reading.

DM 85.00, £ 11.42 This volume embodies the proceedings of the NATO Advanced Study Institute held at Izmir, Turkey in 1971. The participants came from 17 countries in three continents. Although it is dif- ficult to judge for an outsider, the list of contributors sug- gests that many were relatively young workers, which may add in- terest to the book for those well-established in the field. The aim of the organizers was to cover the entire field indicated by the title. K.V.Thimann says in the preface: "Our field has reached a stage of great complexity, and the papers in this vol- ume represent in many respects a phase of much-needed consolida- tion rather than of the opening up of completely new horizons". Most of the 40 papers are research reports averaging about 10 pages in length, while some are condensed reviews of recent work. All papers are followed by group discussions. The papers are grouped in eight sections as follows: I. Basic problems of growth promotion and growth inhibition (4 papers); II. Transport and excretion problems (6); III. Growth regulation in shoots and roots (4); IV. Mode of action of auxins, gibberellins , and cyto- kinins (7); V. Mode of action of ethylene, abscisins, and morph- actins (6); VI. Plant movements and correlations (6); VII. Flow- ering, fruiting and ageing in plants (6); VIII. Growth regula- tion in sugarcane (1). The book is produced in offset print and is not inordinately expensive. The illustrations have come out well, even the elec- tron micrographs. Literature quoted in the discussions is not incorporated in the reference lists. The subject index was pre- pared with great care. 193 20. M.W.MILLER and Ch . C . KUEHNERT , eds. 1972.

Still, we mention ic brief- ly because there are not many recent sources on meristem biology in which the work of so many leaders in the field is brought to- gether. We restrict ourselves to mentioning the subjects of those pa- pers out of the total of 17 that we consider most important from the point of view of plant morphogenesis: Initiation of organi- zation in the root apex (Torrey); mitotic cycle regulation in the root meristem (Van't Hof and Kovacs); meristematic activity in wound xylem differentiation (Fosket); correlative inhibition in the shoot (Cutter); histogen of the shoot apex (Ball); deter- mination of leaf primordia in Osmunda (Kuehnert); control of cell proliferation in root meristems (Clowes); development of meristems in seed embryos (D'Amato); morphogenesis of lateral root primordia (Davidson); development of wheat "gamma plantlets" (Haber) .

Yet much significant work^of general interest remains virtually unknown to biologists outside the field itself. The aim of these volumes is to provide, for both specialist and neophyte, detailed and critical analyses of several aspects of the developmental biology of insects." Thus begins the preface of this collaborative treatise, which will no doubt be very welcome also to those who do not actually work with insects. As will be seen from the table of contents the au- thors could not have been better selected. For reasons of size limitation areas such as regeneration, metamorphosis, cytology, developmental genetics, and biochemistry are not given separate chapters, though each is considered in several places. Detailed 194 technical information also could not be provided, as this would have been at the expense of depth of treatment. There is little or no overlap among the chapters and adequate cross-referencing, and the coverage is remarkably complete in all chapters. The chapters in vol.1 are essentially descriptive in content. In vol.2 problems of pattern formation loom large, and several authors point out how well insect systems are suited for such studies, both at the morphological and (potentially) the biochemical level. As is unavoidable in a book such as this with a long "incuba- tion time", not all chapters are equally up-to-date; some chap- ters have addenda while others do not. The books are profusely and beautifully illustrated. Monographs 22 . G.GIUDICE. 1973.

Enzymatic activities This book is the first comprehensive review of sea urchin de- velopment to appear since 1956. The author has himself worked with sea urchin embryos for at least 15 years. He has judicially selected from the huge literature that portion that has either stood the test of time or holds promise for the future. This work he evaluates carefully, pointing out uncertainties and ma- jor unresolved problems. Just because it is more than a mere compilation, the book will be invaluable as a source for both research and teaching. The treatment of the classical experimental-morphological data is concise, and most of the attention goes to the more recent cell-biological and biochemical work. It is fortunate that Hor- stadius has just published a book in which the former aspects are treated much more extensively (see review no. 23); the two books admirably complement each other. A special feature of the present book is the attention devoted to details of biochemical methodology; this is of course essen- tial to a correct interpretation of the numerous molecular-bio- logical data. Here the reader benefits from the author's exten- sive first-hand experience. The book is well produced and illustrated. The bibliography has more than 1,600 entries and is updated to 1972 in an appen- dix. The subject index is rather short, which somewhat reduces the value of the book as a work of reference. 195 23.

Some aspects of determina- tion This scholarly monograph is mainly concerned with the large body of results obtained from sea urchin embryos since the end of the last century by means of delicate operations .and simple chemical treatments. Most of this work is now considered classi- cal, but is has never before been reviewed so extensively. The author, to whom we probably owe the greatest individual contri-. bution to this field, has provided a synthesis which clearly brings out that the subject is much less simple than most text- books suggest, and that many intriguing problems remain to be solved. The physiological aspects of sea urchin development are only touched upon where this is necessary for the interpretation of essentially morphological results. Those who want more informa- tion on these aspects should consult Giudice's recent book (see review nr.22); this however largely lacks the historical per- spective which is an interesting feature of the present book. Although most of the book deals primarily with the Echinoidea, chapter 8 also reviews work on Asteroidea, Holothurioidea, and Crinoidea. Chapter 9 mainly reviews the classical work on mero- gones and hybrids with particular reference to viability and morphology . The book is attractively produced and illustrated with numer- ous good line drawings. It has a bibliography of more than 450 titles. 24. P.J.PROBST. 1972.

It is not intendea to replace the first-hand study of embryos. It has no text and consists almost entirely of photographs of whole mounts and sec- tions. The inclusion of a chapter on sea urchin development is a useful feature. . . nmmol a Qrirq The first two chapters deal with gametogenesis in mammals, and with maturation and fertilization in Ascaris. Ch.3 deals with sea urchin development (whole mounts of oocyte through late glu- teus), and ch.4 with early development of the frog through tail bud). Consecutive chapters then treat frog embryos ( 4 and 6-7 mm) , chick embryos (stages 5, 8, 11, 15, 18, 21), and finally the 10 mm pig embryo. . , .. „ The photography is superb throughout. Line drawings show the 197 levels of sectioning. An extensive Index and glossary identifies and defines over 450 embryonic structures, and at the same time provides a synopsis of their development. 30. L.RAUNICH. 1972.

L. 9000 (paper) That a second, enlarged edition of this book appears so soon after the first (1970, see Gen.Embryol . Inf .Serv. Suppl.to vol.13, 1970, p. 15) shows that it fills an urgent need. The book is now almost 140 pages longer and has many more illustrations. The text has been improved wherever necessary, making use of the suggestions of many of the author's colleagues. The major addition is a separate chapter on the general and comparative embryology of the vertebrates, with a 44-page sec- tion devoted specifically to human development. Other extensions are in the areas of basic cytology and molecular biology, and elementary developmental genetics. Many of the old illustrations have been regrouped or repro- duced on a larger scale. Twelve very good coloured plates have been added, which in graphical form summarize data on the pro- spective maps, gastrulation movements, extra-embryonic membranes, and placentation of the major vertebrate classes and mammalian orders . 31- B.H.SKOLD and E.KUNZEL. 1972. DAVIS EMBRYOLOGY LABORATORY GUIDE, 48-hour chicken embryo and 10 -mm pig embryo Iowa State Univ. Press, Ames. X,227 pp., 175 figs., subject in- dex. $ 14.50 This atlas is based on a nearly complete manuscript by the late Olive Stull Davis of Purdue University, finished and edited by Skold and Kiinzel. Therefore, Dr. Davis should have been given as the author. The atlas consists of photomicrographs of sections of the 48- hour chick and 10 -mm pig embryo. Special features are (1) the inclusion of a large number of sagittal sections in addition to the transverse ones, and (2) the selection of sections to form a more or less continuous picture (the levels shown are some- times as close as every third section, sometimes much farther apart). For the chick there are 47 transverse and 16 sagittal sections; for the pig these figures are 8l and 31, respectively. All photographs are fully labelled and accompanied by an ade- quate explanatory text. , The photographs are no more than adequate. The majority are too pale and have lost too much contrast in reproduction; some seem to be out of focus. As a result several of the more minute labelled structures are hardly discernible. Otherwise the book is well produced. There are separate indexes to the pictures of the two species. 32. R.L.WATTERSON and R.M.SWEENEY. 1973.

VIII, 205 pp., 19 figs., 38 pis., 4 tabs., subject index. $ 6.95 (spiral bound) The appearance of a third edition of this laboratory manual so soon after the second (1970) testifies to its success. The basic 198 plan has remained unaltered, but large sections of the text have been rewritten and expanded. This particularly holds for the section on the chick embryo, which now incorporates much recent information on oogenesis, ovulation, early morphogenetic movements, and inductive interactions. This basic section can now be used without reference to other textbooks. The number of text figures has been augmented from 9 to 19, and the new figures are excellent. The plates are now printed on glossy paper and are thus even better than in the second edition. A list of 25 research references, all pertaining to chick development, has been added and another new feature is the alphabetical index containing the majority of the terms printed in bold face in the text.

Pregnancy losses and birth defects (Austin) This series of five small textbooks was written mainly for the use of undergraduate students, but is eminently suited for spe- cialists in other fields to update their knowledge of mammalian and human reproduction. (See also review nr.126.) The volume under review was written by five of the best known specialists in the field. They have made every effort to select the most significant material and to stress the most recent ad- vances, all this with admirable clarity and in a pleasant style. Chs.l and 4 devote special attention to the still young branch of mammalian experimental embryology which was initiated by the advent of better techniques of in vitro culture. The numerous excellent drawings and schemes were especially prepared for this book by John R. Fuller. All chapters are con- cluded by useful lists of further reading. The book is well produced . 199 35. F.BECK, D.B.MOFFAT and J.B.LLOYD. 1973.

The "unusual" material re- lates to cell reproduction, chromosome function, and molecular biology (an excellent outline) and includes an outline of gene- tics, polygenic inheritance, and even some population genetics. These together make up part 1 (92 pp.). Part 2 (6l pp.) deals with the uterine cycle, the control of reproductive rhythm, fertilization, early development, and im- plantation. It is concluded by a brief chapter on interacting systems in development. In part 3 (134 pp.) organogenesis proper is treated. The most common errors of development are briefly reviewed for each organ system. Two final chapters deal with postnatal development and with the interaction of heredity, and environment in normal and abnormal development and twinning. Throughout the book the relevance of developmental biology for the study of medicine is stressed. The book is illustrated with simple but very adequate line drawings. It has a brief but useful classified bibliography which includes a list of books for further reading. 36. W.J.HAMILTON and H.W.MOSSMAN. 1972.

There is a new chapter on the physiology of the placenta. The chapter on the cardio-vascular system has been recast, and that on the urogenital system extensively modified. More than 60 new photomicrographs and more than 30 new drawings have been added, and many of the older illustrations have been enlarged and relabelled. A new feature is the inclu- sion of brief surveys of early development and organogenesis in tabular form against ovulation age and embryo size, appended to most chapters. The book is produced in the usual excellent fashion. 37. B.P.KHVATOV and Yu.N. SHAPOVALOV. 1970. EARLY EMBRYOLOGY - Atlas (instructive-methodical textbook) (in Russian) Min. of Publ.

The basic scheme of the book has remained unaltered, but all chapters were revised. The material relating to the chromosomes, originally included under fertilization, is now incorporated in a short new chapter ("Einige allgemeine Prinzipien der Entwicklung" ) together with brief discussions of molecular genetics, the cell cycle, cellular differentiation, and growth. Sixteen new figures were added. The reproduction of the photo- graphs is no better than in the first edition, while that of the line drawings is sometimes too dark. 39. R.S.SNELL. 1972. CLINICAL EMBRYOLOGY FOR MEDICAL STUDENTS Little, Brown, Boston. XII, 360 pp., 246 figs., subject index. $ 4.50 The phrase "clinical embryology" in the title of this book is somewhat odd, but it reflects that the book is a concise, simple account of human development from the clinical point of view. One of its features is that most chapters contain descriptions of the more common congenital anomalies which a practising phy- sician is likely to encounter. The book is purely descriptive in character and its organiza- tion is conventional. There are brief separate chapters on mul- tiple pregnancy; growth and development of the fetus; child- birth; changes that take place at birth; and early recognition, incidence, and etiology of congenital malformations. All chap- ters have reference lists for further reading; some are quite extensive; they are useful, though often the most recent impor- tant literature is not included. The illustrations are for the most part simple, diagrammatic, but very clear line drawings. The book is well produced; a pa- per-bound edition is also available. 40.

X,110 pp., 226 figs., subject index. $ 7.00, DM 22.00 (paper) This is the English translation of a successful French text- book, the revised 2nd edition of which appeared in 1968 (see Gen.Embryol. Inf .Serv. 13, 1969, p. 318). It is essentially a graphic atlas consisting of very clear two- and three-dimen- sional diagrammatic drawings supplemented by good photographic material. Colour is used judiciously in almost all drawings, and the whole is didactically very satisfactory. The text is brief and factual. Adequate attention is given to developmental anoma- lies and f oeto-maternal relationships, and aspects of experimen- tal embryology, comparative placentology , and molecular biology are briefly treated. The translation is no more than adequate; it is often too lit- eral and there are frequent slips. For instance, the notochord is not "formed from" but isolates itself from the entoderm (p. 23), and on p.4l part of a sentence has dropped out, making 201 the rest unintelligible. The translation of "ebauche" by "out- line", of "materiel" by "substance", and of "enchainement" by "linkage" is unfortunate. The book is produced in the same format as its French original. For a review of Vol.11 see nr.4l below. 41. H.TUCHMANN-DUPLESSIS and P.HAEGEL. 1972. ILLUSTRATED HUMAN EMBRYOLOGY. Vol.11 Organogenesis, translated by L.S.

IX, 15^ PP«» 309 figs., subject index. $ 12.70, DM 28.10 (paper) The general features of this volume are the same as those of vol.1 (see review nr.40 above). Each organ system is traced back to its earliest beginnings, thus providing links with vol.1. The systems are treated in the following order: Skeleton and muscles; Face and stomodaeum; Digestive system (with associated exocrine and endocrine glands); Respiratory system; Urinary system; Geni- tal system (primitive, male, female, sexual differentiation); Circulatory system (including hematopoiesis ) ; Ectodermal deriva- . tives (including anterior hypophysis). The most frequent congen- ital malformations are clearly illustrated and briefly described. There are timetables for the digestive system and cardiac devel- opment, and a diagram showing the role of hormones in sexual dif- ferentiation. Sexual anomalies of genetic and hormonal origin are briefly described. The translation is difficult to judge because the original is not available, but it seems adequate. On page 29 there is some confusion over the contribution of the fourth pharyngeal pouch to the thymus or thyroid. Vol. Ill will deal with the nervous system and sense organs (morphology and function), neuroendocrine correlations, func- tional development of the hypophysis, and the paraganglionic system and adrenal gland.

Implications This book is the outcome of a research project supported by the Nuffield Committee for the Advancement of Medicine, Univer- 202 sity of Oxford. It is mainly of interest to obstetricians and paediatricians. The book's aim is "to explore the factors asso- ciated with variations in fetal growth rate, and to make a pre- liminary examination of their peri-natal and post-natal sequelae" Ch.l considers the following general factors: ethnic groups; geographical situation; socio-economic factors; maternal factors; multiple pregnancy; fetal factors; growth curves. The authors' own studies are mainly described in chs.4 and 5, together cover- ing 33 pages. Experimental studies on other mammals relating to fetal-maternal interactions are discussed in ch.3. The hypotheses discussed in ch.6 relate to the following aspects: genetic poly- morphism; ethnic variation; evolution; growth acceleration; gen- der difference; antigenic dissimilarity; parity effect; role of Y chromosome. The book is well printed and well illustrated. It has a bibli- ography of over 500 titles. 44. K.THEILER. 1972. THE HOUSE MOUSE, development and normal stages from fertilization to 4 weeks of age Springer, Berlin, etc. VIII, 168 pp., 335 figs., subject index. DM 124.00, $ 39.40 This is the first complete Normal Table of mouse development to be published, and therefore will be welcome to many. We may be thankful to the author for undertaking this huge task single- handed in the most thorough manner. The book is subdivided into 26 chapters corresponding to as many stages of intra-uterine development, plus one chapter on the neonate and one on postnatal development (with brief des- criptions at 7 and 24 days post partum) . For the first 12 days most of the stages are half a day apart, while the later stages are one day apart. The material consisted of hybrid embryos ob- tained by crossing two inbred strains (female: C57BL/6; male: CBA). Mating times were carefully controlled (+ 2 h; at least, this can be inferred from the preface; the section on procedure is not specific about it). As a rule the most advanced embryos in a litter were taken as being representative for an age group. All chapters contain a table listing the total material used for that stage, which allows evaluation of the stage criteria used and of the variability encountered (which may be very large). Equivalent Streeter horizons for human development are given wherever possible. Each chapter has a concise but comprehensive text which con- siders all essential aspects. For the later stages the text is conveniently subdivided according to organ systems. The earlier chapters contain additional data on the tubal and intra-uterine localization of eggs, on the structure of the corpus luteum, and on the endometrial reactions and placentation. Some histochemical information is also provided. The illustrations, so important in a work of this kind, are of the highest quality, and all are original and based on the pre- sent material. Numerous reconstructions and schematic diagrams are included to clarify complicated relationships. In fact, the later chapters provide a more or less complete developmental anatomy of the mouse (both gross and microscopic), which makes the book valuable for those working on particular organs (al- though not all organs are traced back to their very first rudi- ments). All figures are clearly labelled, but it is a pity that the letter labels on the photographs betray their German origin and are therefore often not self-explanatory to English-speaking 203 readers . The book is beautifully produced and is concluded by a classi- fied selected bibliography of 228 titles, to which reference is made throughout the text. (The references given for organogenesis appear somewhat arbitrary and important recent work is sometimes missed. ) Books of reading 45.

It is not intended as a book en pediatric surgery - the brief sections on treatment are only indications of the ends to be achieved. Rather, the aim has been to provide an organized account of over 200 congenital malformations against a background of normal em- bryology. An important point to be stressed is that the treat- ment is confined to internal organs and does not include the skin, nervous system, sense organs, skeletal and muscular sys- tems, and extremities. Gross body malformations are not treated either. The reasons for these restrictions are not given, but may be obvious to surgeons. The first chapter deals briefly with the incidence, classifica- tion, and etiology of congenital anomalies, with the gestational ages at which they arise, and with the ages and sizes of normal embryos. The rest of the book is a series of 27 chapters, each of which deals with a particular internal organ or organ system, with separate chapters on the anterior body wall, anomalies of sex determination, and body asymmetry in association with splenic anomalies . 204 Each of these chapters starts with a concise but up-to-date account of normal development, which is concluded by a brief summary of critical events. Wherever needed recent histochemical, ultrastructural, or experimental-embryological data are included. In the main part of each chapter each separate anomaly is usually treated successively from the viewpoints of anatomy, embryogene- sis, history, incidence, symptoms, diagnosis, and treatment. Each chapter has a summary table of the anomalies described (stating time of origin and first appearance, sex chiefly af- fected, and relative frequency) and an extensive bibliography. The book is beautifully printed and illustrated. The great ma- jority of figures are taken from other authors, but there are several good original figures and diagrams. The subject index covers 21 pages. 47. J.WARKANY. 1971. CONGENITAL MALFORMATIONS. Notes and Comments Year Book Med. Publ., Chicago. XL, 1309 pp., 660 figs., 12 tabs., subject index. $ 60.00, £ 31.50 The author of this impressive volume is a renowned pedia- trician and at the same time one of the founders of mammalian experimental teratology. The subtitle of the book is definitely over-modest; it is difficult to imagine how a work written by a single author could be more comprehensive. We must be thankful to the author for making his vast experience available to oth- ers . The bulk of the book (Parts IV-XIX) consists of 121 chapters of varying length dealing with structural malformations in man selected because of common occurence or emphasis in the litera- ture; they are arranged in 13 parts mainly according to organs and organ systems. The longer chapters discuss what is known about the genesis and etiology of the malformation, as well as the relevant results of animal experiments. Part I of the book (50 pp.) presents general considerations; of the seven chapters we mention Definitions, Present trends in teratology, Beginnings of experimental mammalian teratology, Syndromes, and Sensitive or critical periods in teratogenesis : uses and abuses of embryol- ogic timetables. All of these contain valuable critical and cau- tionary notes. Part II (5 chs., 75 pp.) deals with etiological factors generally, and is restricted to well-established facts. Part III (9 chs., 5^ pp.) deals with general disturbances of growth and development; the longest chapter is that on intra- uterine growth retardation. Separate chapters on the following subjects were considered but deliberately omitted: inborn errors of metabolism (now a separate discipline), dental malformations, twins and conjoined twins, and monstrosities. The book is very well produced and profusely illustrated with photographs and photo-micrographs, most of them original. Al- though the author states that the literature cited is far from exhaustive, the amount is nevertheless impressive; many non- English titles are included.

Aberrant twinning This monograph is comparable in scope to the author's earlier book "Biochemistry of the Avian Embryo" (1967). It is essential- ly compilatory in nature, and is based on the close scrutiny of more than 6,000 published papers, of which about 900 appear in the bibliography. The significant experimental data were care- fully evaluated, frequently recalculated, and a large proportion were condensed into tables and composite original graphs. The material is presented without discussion or interpretation. The result is an invaluable source book, which however is no substi- tute for a text on avian teratogenesis . The chapters are subdivided into numerous subsections, and al- most any conceivable teratogenic agent or environmental factor is considered. The tables are of considerable help in obtaining a quick overview of published work in certain areas, and this is particularly true of the nine extensive summary tables ap- pended to ch.III and chs.V-IX. Most of the material of course relates to the chick, but other avian species are considered wherever material is available. A 12-page appendix deals with miscellaneous items, particularly the natural variability in various characteristics of chicken eggs which can be of signif- icance in experimental work. Finally, there is a glossary of Greek names of congenital malformations. The book is well produced but very expensive. The original line drawings are successful. Most of the titles in the bibliog- raphy are older than 1969. The bibliography also serves as an author index. The subject index is comprehensive and cross-ref- erenced . 206 Dissertations 50.

The range of topics covered is extremely broad. An interesting feature of the book is that many authors seem to belong to the younger gen- eration whose work is just becoming generally known. About half of the papers will be mainly of value to clinicians interested in drug effects, but at least 20 are of interest to teratologists generally . Most of the papers in question report on recent research in- volving laboratory and domestic mammals and birds. Except drugs in the strict sense, hormones, vitamins, and minerals were used in some studies. Morphological studies are in the majority, bio- chemical work being reported in half a dozen papers, and ultra- structural work in none. Some of the papers are very short. The discussions are not recorded. The book is produced in offset print at a rather high price. The photographic illustrations are well reproduced. The index could have been more extensive.

Vol.1 is entitled Maternal Disorders, and vol.3 Fetal and Neonatal Disorders. They will not be reviewed here. The aim of 208 the present volume is to make use of the normal basic data to explain the underlying mechanisms of the most important disor- ders of maternal-fetal-placental-amniotic fluid interrelation- ships. Much attention is devoted to methodological aspects, to the proper use of diagnostic tests, and to clinical applications. All chapters have extensive and up-to-date bibliographies. The first two chapters are the longest (about 80 pp. and ca. 400 references each). The other chapters range in length from 50 to 60 pages, and have from ca. 100 to over 200 references each. All chapters are clearly organized and subdivided into surveyable subsections. The book is well produced and illustrated. It is not clear why one of the bibliographies deviates from the usage of alphabet- ical order. Monographs 57. F.K.BARTSCH. 1972.

This book concentrates on a rather neglected field of enquiry: the characteristic features 209 of the tumour as a whole. The authorship of the book is truly international, and the chapters are well integrated. The book opens with two excellent reviews of tissue interac- tions in embryogenesis and morphogenesis by Kratochwil and Saxen, respectively. Tarin briefly reviews tissue interactions in adult organs. The next five chapters present histological and ultrastructural studies on human and experimentally induced animal neoplasms, while five other chapters discuss biochemical and transplantation studies on the mechanisms of carcinogenesis and invasion. Systemic effects are excluded from consideration. In the final chapter Cowell discusses the control of epithelial invasion by connective tissue during egg implantation. The book is well produced and very well illustrated. Symposium reports 60. B.SCHWEINITZ and R.DEHNCKE, eds. of journal. 1972.

This is the report of a Symposium held in Jena (DDR) some time during 1971. It contains 56 brief research reports by au- thors from East Germany and various other Eastern-European coun- tries (and a few from West Germany). The subjects of most of the papers fall under one of the following categories: biochem- istry, physiology, and endocrinology of the fetus and neonate; structural and functional studies of the placenta, feto-placen- tal unit, and embryonic membranes; clinical studies on the human fetus and neonate; immunological and immunochemical studies. Five contributions from outside Germany are in English. REGENERATION, RENEWAL (see also 27,80,93) Textbooks 61. M. SINGER. 1973. LIMB REGENERATION IN THE VERTEBRATES Addison-Wesley , Reading, Mass.

Although of course highly selective, this is on the whole a competent and readable review, with one exception: the section on morphogenesis of the regenerate is too incomplete to serve its purpose. Whereas at least some of the most important modern work is mentioned in the other sections, in this section the most recent work is almost totally neglected. With a concise text of this type more illustrations, particu- larly summarizing diagrams, would have been useful. The selec- tion of references is sometimes odd. Monographs 62. P.BRIEN. 1971.

A.L.BURNETT, ed. 1973. BIOLOGY OF HYDRA Academic Press, New York, etc. XVI, 466 pp., 231 figs., 12 tabs., author and subject indexes. $ 29.00 This book is very much the product of one school, that of Allison Burnett. Almost all authors are actual or former asso- ciates of Burnett. The book is distinctly biased on several is- sues; a much better balance of viewpoint could have been achieved if members of other "Hydra schools" had been asked to contribute. Nevertheless, the influence of Burnett's school in this field is considerable and its production impressive, and the book provides a useful synthesis of the manifold approaches and often very interesting results of this group. It is much less useful as a general work of reference. We only mention in passing that the first three chapters deal with the behaviour and ecology of Hydra. Most of the remaining chapters are lengthy, self-contained reviews supplemented with unpublished material. Although the treatment draws rather heav- ily on the group's own work, the most important work of other schools is usually covered. An exception is the most recent work of the groups of Wolpert and Gierer. Chapters by Diehl and Lesh-Laurie deal with I-cells and with organismic polarity, respectively, while Davis extensively treats the ultrastructure of gastrodermal regeneration. The next five chapters deal with epidermal regeneration and are in the format of brief research papers; this is because most of the work in this area is very recent. Three chapters by Davis then deal with the ultrastructure of differentiating and mature ner- vous elements of three types: neurosensory, ganglionic, and neu- rosecretory. A long chapter by Corff deals with organismal growth and the role of cell proliferation. Finally, Hausman dis- cusses the mesoglea and its possible morphogenetic role. 64. B.M.CARLSON. 1972.

S.fr. 49.00, $ 13.75, £ 5.40, DM 44.00 The author of this monograph has himself been doing experi- ments in this area for several years. Moreover, he knows Russian and other Eastern-European languages and has frequently visited several countries in Eastern Europe where much work along these lines is being done. The book presents original data from his own research and that of three of his doctoral and several of his graduate students on frogs, axolotls, and rats. This material is integrated with the major findings and conclusions of the "Russian school". The following main aspects are treated successively: gross de- velopment, histological development, autoradiography, nerve sup- ply, biochemical characteristics, factors determining gross form and internal architecture, and homografting experiments. The book is well produced and beautifully illustrated, mainly with photomicrographs. It has a 9-page bibliography but no index. 211 65. L.V.POLEZHAEV. 1972. LOSS AND RESTORATION OF REGENERATIVE CAPACITY IN TISSUES AND ORGANS OF ANIMALS, translated from the Russian by Y.Halperln Harvard Univ. Press, Cambridge, Mass. X,385 pp., 123 figs. $ 10.- This is the translation of a book first published in Russian in 1968. The author is head of the Laboratory of Experimental Morphology, Institute of Developmental Biology, Academy of Sciences of the USSR, Moscow. As B.M.Carlson points out in his preface to the translation, Soviet regeneration research under- went a pronounced shift in the late 1940s from basic work on amphibians to more practically oriented problems in mammals. The book in particular summarizes the work of the author and his as- sociates during the post-war years, which is much less known in the West than his earlier work. The book is written in the verbose and somewhat involved style typical of Russian writers of an older generation. Moreover, there is a rather strong preoccupation with theoretical issues which may seem to be of only academic interest to many. However, the organization of the book is such that the highly interesting factual results of this group are not too difficult to unearth. Although it may sound surprising, they will probably appeal most to members of the medical, dental, and veterinary professions, and might well open up entirely new ways of surgical treatment in the not too distant future. The first part of the book lays the theoretical foundation (eight brief chapters, 79 pp.). The second part (six chapters, 188 pp.) then deals with experiments on the loss and the resto- ration by various means of regenerative capacity in the follow- ing systems: extremities of amphibians, lizards, and young rats; bones of the cranial vault; dental tissues; myocardium; cerebral cortex; X-irradiated axolotl limbs. In the last part (five brief chapters, 36 pp.) the insight gained is applied to some other areas: restoration of damage to internal organs, functional res- toration, and relationships between regenerative capacity, immu- nity, and tumor formation. The translation is very competent. The book is well printed in offset print, well illustrated, and remarkably cheap. The 77- page classified bibliography is separated into Russian and non- Russian titles (proportion ca. 2:1). All Russian titles are transliterated as well as translated. There are no indexes. 66.

X,190 pp., 108 figs., subject index. $ 14.- It is unfortunate for the publisher of this book that an excel- lent English translation of Polezhaev's 1968 book on the same subject has just appeared (see review no. 65). The present book is a considerably shortened version of the earlier work, espe- cially written for American readers. It restricts itself almost entirely to factual results. Although the book contains some work more recent than 1968, it compares unfavourably with the translation in almost every respect (even the price). The English is clumsy - the author is not to blame, of course, but why has nobody suggested a linguistic check by an expert? Almost no care seems to have been devoted to the preparation of the graphs and figures. The former are unbelievably amateurish in execution. The latter have bad captions, are not properly la- belled, and the component pictures are often transposed or ro- 212 tated in an inexcusable manner. Moreover, even though printed on glossy paper, they are often inferior in quality to the corres- ponding ones in the other book; several lack contrast, some of the blocks seem to be badly scratched, etc. The only positive point is the presence of an index.

It has now grown to four volumes; many of the chapters were revised by the original authors, and several new chapters were added. We will only review vol.1, which contains four chap- ters that are of particular interest to our readers. The first and longest of these is that by Fischman (74 pp.). It briefly discusses the embryonic origins of muscle, but most of it is taken up by the treatment of the myoblast concept, mi- tosis, cell fusion, and the myotube. Most of the emphasis is on DNA synthesis, general ultrastructure , and the nature of myofil- aments and myofibrils. The histochemistry of developing skeletal and cardiac muscle is treated in the revision of the original chapter by Beckett and Bourne (30 pp.). Goldspink discusses the postembryonic growth and differentiation of striated muscle (58 pp.), devoting attention to structural, ultrastructural, biochemical and physiological changes, and to factors that in- fluence muscle growth. Murray deals with skeletal muscle in cul- ture (63 pp.); one section of this chapter deals with the in- sights tissue culture has provided into the early histogenesis of muscle (induction, sarcoblast derivation, cytodiff erentia- tion); another section deals with some histogenetic aspects of muscle regeneration as elucidated by tissue culture. (Muscle re- generation as such will get a systematic treatment in vol.11, in 214 a chapter by Hudgson and Field.) The book is very well produced and beautifully illustrated. 74. H.C.SLAVKIN and L.A.BAVETTA, eds. 1972. DEVELOPMENTAL ASPECTS OF ORAL BIOLOGY Academic Press, New York, etc. XVI, 426 pp., 198 figs., 20 tabs., author and subject indexes. $ 26.00 This multi-author treatise is of much wider interest than to members of the dental profession alone. The reason is threefold: first, oral biology is placed against a broad biological back- ground; second, the chapters are not didactic reviews, but re- flect judicious "pruning" so that they remain readable and en- joyable for the non-specialist; and, third, the authors have been urged to outline the broad biological issues involved and to point out critical unsolved questions. Of the 21 contributors the majority are North-American, with two from England and one from Belgium. Most of them work in the research departments of dental schools. Throughout the book the discussion considers all levels of organization, from the orga- nismal down to the molecular. The broad scope of the book is reflected in the variety of subjects considered. Of the 18 chapters seven deal with tooth and periodontium, and five with other oral tissues and organs (neural crest, cephalic mesoderm, palate, taste bud, gingiva, salivary gland). Four chapters discuss general problems (nutri- tional aspects of embryogenesis , molecular developmental biolo- gy, immuno-embryology , collagen biochemistry), while two others deal with normal and malignant lymphoid cells, and with the re- lation between epithelial carcinogenesis and the possible role of the mesenchyme. Most chapters range in length from about 15 to 30 pages; all have up-to-date bibliographies. The book is exceedingly well produced and profusely and su- perbly illustrated. Monographs 75.

Press, Baltimore, etc. X,80 pp., 19 pis. $ 10.00, £ 4.75 This atlas is based on a study conducted at the Laboratory of Embryology of the Instituto Nacional de Cardiologia de Mexico. It contains 19 composite full-page plates printed on high-quality paper, each accompanied by a concise text. The developmental pe- riod covered is from 26 hrs. till hatching, comprising 18 stages of the Hamburger/Hamilton series selected to show the most con- spicuous changes (the first stage being st.8 and the last st.44). Separate plates are devoted to the heart and great vessels in the newly hatched chick, and to the formation of the interatrial septum. Until st.32 most plates include good diagrams illustra- ting the embryonic human heart at comparable stages, mostly taken from classical sources. Up to and including st.22 the chick embryos were stained and photographed as whole mounts, thereafter the fixed hearts were photographed in toto or after partial microdissection, as seen from various sides. The text, based on personal observations only, is clearly written and contains references to those developmental disorders which give rise to the most common congenital heart defects. The illustrations are of outstanding quality and are clearly labelled. The book is concluded by a brief selective bibliogra- phy. The production is luxurious but the format somewhat un- wieldy; the price is surprisingly low thanks to a Mexican grant. 78. W.KIRSCHE. 1972.

Sfr. 93.00, $ 22.30 This monograph deals with a comparatively new approach in bio- chemistry, that based on chemical patterns of tissues. The au- thor calls it "chemical anatomy" and shows that it may develop into a tool at least as effective as histology and cellular pathology. It is based not on individual tissue constituents but on the differential patterns of concentration or activity of the same constituents in different tissues. Pioneer work in this area was done by J . P.Greenstein a quarter of a century ago. The author's main concern is with enzyme activities in tissue extracts (not with chromatography, electrophoresis, etc.) with emphasis on fetal, adult, and regenerating rat liver and various rat tumours. He shows that meaningful comparisons can be achieved by using a common tissue base (1 g of fresh tissue) and by ex- pressing all activities in "liver units" (the unit being the ac- tivity in adult rat liver). The resulting patterns are then sub- jected to correlation analysis and principal component analysis. The methodology is set out with clarity. The book is based on original results and on numerous re-eval- uated data of others. It considers 160 components in 17 differ- ent rat tissues, compiled in tabular form and in the form of histograms and graphs. The book is essentially an inventory and analysis of crude data, and no attempt is made to explain under- lying regulatory phenomena. The results of most interest to de- velopmental biologists are the consistent differences in enzyme patterns between fetal and adult tissues; the similarity in pat- terns among various tumours and between tumours and fetal tis- sues; and the correlations between growth rate and tissue pat- tern, which are different for fetal and neoplastic tissues. 81.

The introduction briefly discusses the main phases of the life cycle of these cells: mitosis, differentiation, and exfoliation. The five main chapters then deal with the salient features of the epithelial portion of the skin and its appendages in the five vertebrate classes, with emphasis on ultrastructure. The chapter on avian epidermis consists of brief sections on skin 217 development in the embryo and on feathers and their development. The chapter on mammals contains sections on fetal epidermis and on the three phases of the hair growth cycle. The booklet is superbly illustrated with electron micrographs and half-tone drawings. 83.

DM 46.00, $ 14.60 It is fitting that this volume should be dedicated to Ernst Hadorn. The dedication is by D.Bodenstein and accompanies a de- lightful portrait of the great Swiss biologist. All the contrib- utors have at one time been associated with Hadorn. The six reviews making up the volume are comprehensive and well organized, and as up-to-date as is possible in such a book. There is some overlap between the chapters, but this is inevita- ble and suitable cross references are provided. The subjects treated successively are larval development (Nothiger), the sta- bility of the determined state (Gehring), pattern formation (Garcia-Bellido) , fine structure (Ursprung), biochemistry (Fris- trom), and hormonal control (Oberlander ) . The chapter by Gehring is a revised and updated version of an article that appeared in vol.1 of this series. Several chapters contain unpublished work; this holds particularly for Fristrom's chapter, which is the first published review in this area and clearly brings out the molecular-biological parallels between imaginal disc development and embryogenesis in other species. The book is produced and illustrated in the usual excellent manner, but as in the other volumes of the series the absence of indexes is regrettable. 84. C.VAGO, ed. 1972.

Embryol. Inf. Serv. Suppl.l_4, 1972, p. 34. The present volume is in three parts, the first dealing with embryo and organ culture (3 chapters), the second with various applications of in- vertebrate tissue culture (7 chs.), and the third being a cata- logue of invertebrate cell lines compiled by Hink (with formulas of 22 culture media). All three chapters in part one are of interest to developmental biologists. Demal and Leloup deal with insect organ culture with particular reference to morphogenesis (38 pp.); they pay special attention to the brain and the eye-antennal imaginal discs, the thoracic discs, the circulatory and digestive organs, and the gonads. Gomot reviews organ culture in invertebrates other than insects, arranged according to nine major phyla (95 PP«)j the chapter has several sections on the culture of regeneration blastemas. Finally Takami deals with insect embryo culture in a review centered on Bombyx mori (27 pp.). In part two the following chapters may be mentioned: Barigozzi on cell culture in genetic research (centered mainly on Drosophi- la), and Berreur-Bonnenfant on organ culture in hormonal research 218 (postembryonic development, regeneration, and sexual differen- tiation). Most of the other chapters deal with applications of invertebrate tissue culture in pathology. The book is well produced and illustrated. 85. Ch.VERMEIJ-KEERS. 1972.

It had 40 invited participants, most of them from North America, while 200 others attended and took part in the discussions. We will only review part I, which deals with the development of muscle; part II (14 papers) is en- titled "The muscle spindle and the Golgi tendon organ". The 15 papers in part I are all reports of recent results, partly unpublished in 1970. Most of them have an average length of 15 pages, and several were amplified prior to printing. They deal with structural, biochemical, and molecular-biological as- pects of muscle development in vivo and in vitro, involving nor- 220 mal or dystrophic muscle tissue of mammals, the chick, and the lizard. Each group of two or three papers is followed by 2-k pages of highly interesting discussion, with separate references. The book is very well produced and profusely illustrated, most- ly with very good light and electron micrographs. Unfortunately the price must be considered excessive. 93. R.J.GOSS, ed. 1972.

Most of the 23 contributors work in bio-medical institutions and departments. The Symposium was meant to encourage the exchange of ideas among people whose paths do not ordinarily cross. It is therefore a pity that the discussions are not recorded; nevertheless, the book is valuable for the breadth of its coverage. There are introductory chapters on theories of growth regula- tion (Goss) and on growth and renewal (Leblond). In the remain- ing 16 chapters a great variety of mammalian organs and tissues pass in revue, most with emphasis on postnatal growth: brain, muscle, heart, skeleton, blood, lymphatic system, liver, kidney, lung, and several more. Each chapter is a review by a specialist of recent work, seldom more than 10 years old, and together they constitute an excellent overview of the field. The multitude of regulatory factors that emerge should be an incitement to much more investigation. The book is well produced and illustrated.

However, the cell cycle is so basic to all biological research, and the book is so well-balanced and au- thoritative that we briefly review it as a service to our readers. It consists of a series of concise but well-organized and clearly written reviews which cover nearly every aspect of the subject in a thoroughly modern fashion. Literature data are often condensed into very useful tables, and extensive bibliog- raphies are provided. The chapters are linked together singly or in groups by thoughtful introductions by the editor. We restrict ourselves to enumerating the subjects of all chap- ters (except the two that deal specifically with cancer cells): proliferative cycle of mammalian cells (Lipkin); proliferation and maturation of hemopoietic cells (Blackett); critical evalua- tion of the FLM method (Mendelsohn and Takahashi); differentia- tion and the cell cycle (Malamud); effects of hormones on the cell cycle (Epifanova); biochemistry of growth initiation in resting cells (Cooper); cytophotometry and histochemistry of the cell cycle (Vendrely); biochemistry of Gl and S phases (Mueller); 221 biochemistry of G2 and mitosis (Tobey et al.); radiobiology and the cell cycle (Frindel and Tubiana).

D.Kr.195.00 This book contains the papers read during the First Interna- tional Conference on Cell Differentiation (held in the summer of 1971 in Nice, France - this information is not to be found in the book). It is unfortunate that the book bears the same title as a multi-author treatise published in 1970 (Schjeide and De Vellis, eds.). The Conference had a widely international atten- dance. Its chief aims were "to define important questions and to indicate the available experimental models and suggest new ones, in a series of short presentations". Most of the papers are very short and avoid technical detail. Most report on unpublished or very recently published work, while some are reviews or are of a theoretical nature. The range of cell systems and methods covered is astonishing. In the list of speakers one encounters many of the "big names" one would ex- pect, but the majority of the authors seem to belong to a young- er generation, which is very refreshing. The book is fascinating "browsing" material if one wishes to acquire a broad idea of what is going on in the field at this very moment, and particu- larly where new frontiers are being opened up and new interdis- ciplinary approaches tried out. However, if one wants details one would have to go back to the relevant journal articles. Nevertheless, despite its heterogeneity (or perhaps just because of it) the book may be expected to serve as an eye-opener to many . No less than 65 papers are arranged (admittedly more or less arbitrarily) in four sections as follows: Embryology (12 papers, with relatively most of the "big names"); Immunology (9); Can- cerology (18); Cell biology (26). The last section is concluded by a brief synthesis of the final round table discussion on cell biology and differentiation. The editing of the papers has been minimal, resulting in a lack of editorial uniformity that is sometimes irritating. The book is beautifully produced and illustrated, and not too expensive for its value; the more the pity that it is disfigured by numerous printing errors. There is no subject index. The so- called author index is really an index to contributors; it is not clear why only first authors are included. 99. L.G.SILVESTRI, ed. 1972. CELL INTERACTIONS; Proceedings of the third Lepetit Colloquium North-Holland, Amsterdam. 324 pp., 79 figs., 46 tabs., subject index. D.fl. 45.00, ca. $ 18.00 (paper) This Symposium was held in London in November, 1971, and was attended by an international group of experts. All the papers describe very recent work, and although they vary in length and some of them are little more than abstracts, most are highly in- teresting particularly for those who want new information on cell surface properties and intercellular messengers. We mention only those papers which have a direct bearing on developmental biology. In the section on cell interaction and differentiation (7 pa- pers) there is first of all an important and stimulating paper by 223 Bennett, Boyse, and Old on cell surface Immunogenetics and the study of morphogenesis. Weston deals with cell interaction in neural crest development, and Robertson et al. with cellular in- teractions in slime mould aggregation. Papers by Humphreys on contact inhibition of growth and by Pitts on intercellular nu- cleotide exchange are well worth reading. The section on intraneural interactions (6 papers) contains papers by Sidman on cell interactions in the developing mammal- ian brain; by Horridge on cell specificity and precision of con- nectivity in differentiating invertebrate neurons; and by Giaco- bini on the role of regulatory mechanisms of neurotransmission in the establishment of synaptic connections in developing avian ganglia. Two papers in the section on immunology (18 papers) should be mentioned: that by Greaves and Janossy on a model for antigen-induced differentiation based on lymphocyte activation, and that by Mandel et al. on interactions of epithelial and lym- phoid cells in the differentiating thymus. The book is produced in offset print from typed manuscripts. The discussions held at the Symposium are not recorded. 100. H.C.SLAVKIN, ed. 1972.

Biophysical properties of con- nective tissues Session moderators: Slavkin, Beierle, Meyer, Sognnaes, Nimni, Petruska This book contains the proceedings of a Conference held on Santa Catalina Island, Calif, in June, 1972. Of the 60 partici- pants the large majority were Americans; eight came from coun- tries outside the U.S.A. The aim of the Conference was not to review the well-documented aspects of matrix biology but to en- gage in intensive informal discussions of contemporary issues. No formal papers were presented; each session is a continuous discussion led by the session moderator, who had previously framed a number of questions which are printed at the beginning of the session. The rough draft of the discussions was edited on the spot by the participants and produced in offset print at remarkable speed by Academic Press Rapid Manuscript Reproduc- tion. The book is not suitable as an introduction for the uniniti- ated, but will be read with great profit by those actively en- gaged in matrix biology. The first two sessions are of particu- lar interest to developmental biologists. They contain attempts at re-evaluation of organogenetic induction and the expression of potential during cell differentiation, and suggest new ap-^ proaches to the epigenetic influence of the cell matrix (parti- cularly collagen); both of these in a variety of systems, some of which are relatively unknown to most developmental biologists (e.g. corals, mollusc shells). Literature references are given in the text, and numerous good illustrations are included. It is sometimes confusing that the figure legends are printed in the same type as the text.

Factors controlling the conversion of triosephosphates to lactate in the loach embryo; Appendix: Allosteric regulation of enzyme activity The authors of this monograph have been active investigators in this field since about 1965 and have produced a long series of joint papers written mostly in Russian. The book reviews this work, carried out on eggs and embryos of the loach, Mis- gurnus fossilis, in connection with the work of many others on eggs and embryos of fish and other animals. The book is largely characterized by the table of contents. Particular attention is devoted to a comparison of the metabo- lism of oocytes and embryos, since in the loach the Embden- Meyerhof pathway emerges during the phase of rapid growth of the oocyte. The period of early embryogenesis considered rough- ly extends till the end of gastrulation. The stability and self-adjustment of metabolic systems during development by feedback control in several controlling steps is extensively discussed. The book is well produced and has a 13-page bibliography that is up-to-date until about 1969/70. There are no indexes. 102. H.URSPRUNG, ed. 1972.

XI, 76 pp., 29 figs., 12 tabs., DM 36.00, $ 11.50 This volume brings together six articles by investigators ac- tive in developmental and cell biology who use nucleic acid hy- bridization as a tool in their research. Contrary to what the title suggests, only the first two papers have a direct bearing on cell differentiation, while the others are mainly concerned with the wider area of gene regulation at the biochemical level. Not all papers are equally up-to-date. Tobler briefly reviews the problem of the genetic identity of different cell types, basing himself on data from a variety of organisms. Church and Brown discuss the tissue specificity of genetic transcription, mainly on the basis of their own work on mouse embryos (a welcome complement to the numerous studies on sea urchins and amphibians). The paper by Purdom, Williamson, and Birnstiel is largely methodological in character. Hybridiza- tion of nucleic acids to chromatin and to chromosomes, respec- tively, is discussed by Kim and by Steffensen and Wimber. Final- 225 ly, Huang and Smith deal with the nature of chromosomal protein- bound RNA and Its possible role In gene transcription. The book is well produced but has no indexes. Dissertations 103.

A limited number of copies are available from the Re- productive Endocrinology Research Unit at the Karolinska Sjuk- huset, Stockholm. The book contains the papers read and discus- sions held at the fifth international Karolinska Symposium, Stockholm, May 1972. Although most of the 20 papers have no di- rect bearing on development, the book contains such a wealth of recent information on many aspects of molecular biology that a brief review is considered appropriate. Three papers deal directly with developmental problems: Brown, Mattoccia and Tocchini-Valentini on the role of RNA in gene am- plification in immature Xenopus ovaries; Kafatos on mRNA and cell differentiation in the silkmoth galea; and Turkington and Kadohama on gene activation in mammary cells in vitro. The other 17 papers deal with such diverse subjects as nuclear and chromo- somal structure and biochemistry, morphology and chemistry of transcription, DNA antibodies, RNA polymerases, and control of gene expression by cyclic AMP and steroids, all studied in wide- ly differing systems. The discussions have their own references. The 14-page general discussion at the end of the book centres on two major areas: chromatin structure (and the pitfalls of reconstitution studies), and possible new systems for the study of reproductive molecular biology. 105.

X,191 pp., 82 figs., 25 tabs., author and subject indexes. £ 4.00 This volume contains what is apparently a selection from the papers presented at the seventh FEBS meeting held in Varna, Bul- garia in September, 1971. Twenty-one of the contributors are from Western Europe, 12 from Eastern Europe, and seven from North America. Almost half of the 21 papers are no more than ab- stracts or preliminary notes of one or a few pages. They may be 226 interesting to the specialist but it is not clear what is the purpose of including them in a book. Unfortunately, several con- tributions of potential interest by less well-known investiga- tors are in this category. From among the longer papers we single out the following as being of possible interest to our readers: Induction of gluta- mine synthetase in embryonic neural retina (Moscona, 24 pp.); Cell-cycle-dependent events during myogenesis, neurogenesis, and erythrogenesis (Holtzer et al., 14 pp.); RNA synthesis in giant chromosome puffs (Pelling, 14 pp.); and Specific biological in- hibitors of protein synthesis in differentiated cells (Kruh et al., Paris, 12 pp.). Papers of less than ten pages deal with ribosomal genes during amphibian oogenesis (Crippa and Tocchini- Valentini), RNA transcription from single copy DNA during mouse development (Church and Brown), and hormonal receptors of chro- matin and their possible role in ontogenesis (Salganik et al., Novosibirsk) . Several other papers, e.g. those by Bishop, Georgiev, and Stenram (Sweden) are of interest to molecular biologists but not specifically to developmental biologists. 106.

MOLECULAR GENETIC MECHANISMS IN DEVELOPMENT AND AGING Academic Press, New York, etc. XII, 254 pp., 83 figs., 31 tabs. $ 8.50 Contributors: Baird, Blumenfeld, Chen, Clever, Lang, Massie, Painter, Patel, Rockstein, Samis, Stidham This book contains the papers presented at a Symposium held in Miami, Fla. in March, 1972. It is one of the first volumes produced by Academic Press Rapid Manuscript Reproduction, and the speed of publication is indeed remarkable. This was achieved in part by the use of offset print, and no doubt also by adequate urging of the participants to produce their manu- scripts in time. The two editors, both from the convening Department of Physi- ology at the Miami School of Medicine, are active in the study of ageing processes in insects, and it would have been fair to indicate in the title that all of the nine review and research papers making up the book report on work done on insects. The borderline between development and ageing is vague and almost all papers are of interest to developmental biologists. They deal with a variety of subjects ranging from the hormonal con- trol of cellular growth and death via overall nucleic acid, pro- tein, and enzyme biochemistry to molecular biology (examples of the latter are satellite DNA and soluble DNA). One paper deals with ovarian maturation, oogenesis and embryogenesis . Another paper compares findings obtained in rodents with data on insects The book is well produced at a very reasonable price. 227 DEVELOPMENTAL PHYSIOLOGY (incl. endocrinology, immunology, be- haviour, etc.) (see also 2,17,19,22,52,56,60,74,106,130) Monographs 107.

Mythology and science; 2. Review of problems; 3. Properties of the offspring and mother; 4. The placenta as a filter; 5. Immunological inertia; 6. Enhancement; 7. An in- tegrative hypothesis; 8. Other immunological aspects The author of this concise research monograph writes in his preface: "The important facets of the possible mechanisms that avert immunological destruction of the fetus by the mother and allow fetal immunity to develop without reacting to maternal an- tigens in humans remain speculative. The available clues to an understanding of these mechanisms indicate that the depression of some immune responses during pregnancy resembles other sorts of adaptive immunity such as "tolerance", "paralysis" and "enhance- ment", also that firm correlations exist between the fetus-mother relationship and the surgical transplant-recipient and cancer- host relationships". This sets the scene for an authoritative and highly interesting discussion of these subjects on a broadly biological basis in eight short chapters, the titles of which speak for themselves. The aspects which are considered in the concluding chapter are artificial inertia, hemolytic disease, and infertility. Each chapter has its own selective reference list. Apart from this, there is a 48-page, up-to-date classified bibliography (9 sections) which covers the literature much more completely and shows hardly any overlap with the chapter references. The book is illustrated with ten photographic plates bound in the middle of the book. 108. A.C.BARNES and A. E. SEEDS, eds. 1972. THE WATER METABOLISM OF THE FETUS Thomas, Springfield. X,171 pp., 36 figs., 38 tabs., subject in- dex. $ 15.75 Most of this book deals with amniotic fluid and with water and electrolyte exchange among uterine compartments. The book is mainly meant for clinicians, and all authors are obstetri- cians or pediatricians. However, some chapters contain informa- tion that may be of interest particularly to human embryolog- ists . This holds particularly for the chapter by Biggers (29 pages), in which he reviews modern work on the origin of blastocoelic fluid and the formation of the blastocyst in mammals, and points out possible parallels with amnion formation. Seeds briefly treats the biophysics of intra-uterine water transfer in preg- nancy (16 pp.), and then deals more extensively (26 pp.) with various aspects of amniotic fluid per se, such as its volume and chemical composition throughout pregnancy and their regulation, fetal urine production, and fluid exchange between amniotic fluid, fetus, and maternal organism. A chapter by Nadler (17 pp.) is mainly a compilatory review of biochemical components of am- 228 niotic fluid and of cells Isolated from it, with a long bibli- ography. The other four chapters are of clinical importance only, 109. H.E.PERSSON. 1973. DEVELOPMENT OF SOMATOSENSORY CORTICAL FUNCTIONS, an electrophysiological study in prenatal sheep Scand. Physiol.

Hormonal and dietary factors in the develop- ment of digestion and absorption; 6. Metabolic changes in children with protein-calorie malnutrition This book was written by an international team of experts: five Americans, four Jamaicans, two Australians, and one Cana- dian. All chapters are synthetic reviews and all deal with pre- and postnatal mammals and man. The subject is discussed against a broad biological background. Ch.l (by Adolph; 22 pp.) views the emergence of physiological regulation in the fetus and neonate in a broad context and serves as a theoretical introduction to the volume. Chs.3 and 5 are the longest (50 and 66 pp., respectively); the other chap- ters range in length between 26 and 38 pages. As the various chapters were apparently not written at the same time, their bibliographies are not equally up-to-date. Sev- eral chapters contain much tabular material; the illustrations are confined to graphs. The book is well produced. Dissertations 111. H.van der HELM-HYLKEMA. 1973.

It was attended by an international group of specialists in which North Americans and Scandinavians predomi- nated. The book is not only of interest to physicians but partly also to mammalian embryologists (more than is apparent from the session headings listed below). Most of the 29 papers contain review material and original research data in varying propor- tions. The majority range in length from ca. 10 to 25 pages; there is one paper of 72 pages on cholinergic function in the developing fetus. The range of subjects covered is very broad. Apart from the closing session, which contains a brief report of a discussion on some biochemical and pharmacological aspects of the develop- ing embryo, the main papers are grouped into five sessions as follows: Drug distribution (8 papers); Drugs and autonomic func- tion (9); Drug metabolism (6); Drugs and the blastocyst (2); and a session containing a paper on the theory of fetal drug equilib- ration and one on the contributions of teratology to fetal phar- macology. 113.

D.fl.35.00, $ 12.75 The CIBA Symposium volumes hardly need recommendation any more. The present Symposium was held in November 1971. Among the 14 papers five are of predominantly clinical significance. Of particular value are the extensive discussions, complete with references. They are characterized by a lively exchange of in- formation between laboratory workers and clinicians. Among the more biologically oriented papers we want to single out the following as being of general interest to our readers: Owen on the development of lymphocyte populations; Adinolfi on the ontogeny of complement and lysozyme; Stites et al. on the development of cellular immune competence in man; and Beer and Billingham on the uterus as a graft site and the foetus as a natural homograf t . The remaining papers in this group are either more theoretical or more specialized in nature, but all will be of great interest to the specialists in this field. The Symposia are now produced by another publisher, on much better paper and with a sturdy cover. This has entailed some price increase, but the price is still very reasonable. The in- dexes refer not only to the papers but also to the discussions. 114. R.S.COMLINE, K.W.CROSS, G.S.DAWES, and P. W. NATHANIELSZ , eds . 1973. FOETAL AND NEONATAL PHYSIOLOGY Cambridge Univ. Press, London, etc. XXIV, 64l pp., 253 figs., 17 pis., 76 tabs. £ 11.60, $ 32.50 This volume contains the papers read at a three-day Symposium held in Cambridge, England in July 1972. Of the 66 contributions, the great majority are by American and English workers (49), five 230 each are from Australia and Canada, and the remainder from Swe- den, France, and New Zealand. The organizers have made an ef- fort to cover a very wide field, with emphasis on those areas where research is particularly lively. An area that was expli- citly excluded is foetal immunology. The contributions vary widely in character, and deal with a variety of mammals including man. About two-thirds are from a few to about ten pages long; most of these are concise research reports, while some are hardly more than abstracts. The remain- der range in length from ca.15 to 25 pages and are usually mix- tures of review and research report, but occasionally restrict- ed to recent review material only. The papers are arranged in seven sessions as follows: Central nervous system (11 papers); Circulation and breathing (12); Placental function (10); Metab- olism (11); Endocrinology (10); Parturition (8); Surfactant colloquium ( 4 ) . In the interest of rapid publication the discussions were not included, and no indexes or list of contributors were compiled. Although the speed of publication is indeed remarkable, it is doubtful whether this outweighs the lack of indexes. The book is very well produced and well illustrated. 115. J.J.MENN and M.BEROZA, eds. 1972. INSECT JUVENILE HORMONES: Chemistry and action Academic Press, New York, etc. XVI, 341 pp., 63 figs., 57 tabs., subject index. $ 11.00 This is the report of an ail-American Symposium held in Washington, D.C. in September, 1971. It was attended by scien- tists representing universities, government agencies, and in- dustry, and its primary focus was on the possible use of juve- nile hormones and their analogues as pesticides. However, the scope of the Symposium was much wider than this, and scientists working on any aspect of JH research will find the book useful and interesting. The contributions were reproduced in offset print from typescript copies in the interest of rapid publica- tion; this has led to some overlap and some inconsistency in nomenclature. The discussions are not recorded. The 14 contributions deal with biological (6 papers), bio- chemical (3), and chemical (5) aspects. Three papers in the first group deserve special mention: Williams and Kafatos on theoretical aspects (proposing a model in which JH participates in the negative control of master regulatory genes coding for RNA polymerase); Ilan, Ilan and Patel on JH effects at the translational level; Riddiford on JH and insect embryonic de- velopment. In the second group attention is focussed on the me- tabolic breakdown of JH in insects, mammals, and the environ- ment . Books of readings 116. V.H.DENENBERG, ed . 1972.

Environmental 231 enrichment; 11. Infantile stimulation; 12. Maternal influen- ces; 13. Social factors This book of readings is concerned entirely with postnatal be- haviour in mammals and man. It has been organized in such a way that broad principles can be derived which apply to animals and humans alike. In each chapter the papers reporting on human studies illustrate the same principles as the papers dealing with animal experiments. Of the 65 papers, 21 deal with the hu- man, 23 with the rat, and 21 with four other mammalian species. Each of the chapters 2 to 13 consists of between four and seven short to medium-length papers. Sometimes somewhat older papers were intentionally selected rather than very recent ones. Ch.l is a lengthy and thoughtful introduction to the entire field covered by the book, and has its own references. Each chapter is opened by a very good introduction of a few pages, with separate references, in which the readings are placed in proper perspective and briefly characterized. Together these introductions provide an excellent brief survey of the field.

This is a highly competent, well-written and well-illustrated review of an important field of enquiry. The only odd point is the statement on the first page that "There is no known way of making a cell committed to one kind of differentiation change into a cell of another kind". One immediately asks: What about lens regeneration from the iris in the eye of urodeles? This phenomenon, admittedly the only well-established case of cellu- lar metaplasia in a vertebrate, is not mentioned in the text. There are a number of confusing printing errors. Monographs 118. W.BEERMANN, ed. 1972. DEVELOPMENTAL STUDIES ON GIANT CHROMOSOMES Springer, Berlin, etc. Results and problems in cell differentia- tion Vol.4. XVI, 227 pp., 110 figs., 14 tabs. DM 59.00, $ 18.70 Contents: 1. Chromomeres and genes (Beermann); 2. Chromosomes isolated from unfixed salivary glands of Chironomus (Lezzi and Robert); 3. Replication in polytene chromosomes (Rudkin); 4. Transcription in giant chromosomal puffs (Pelling); 5. Puffing patterns in Drosophila melanogaster and related species (Ash- burner); 6. Relation of puffing to bristle and footpad differ- entiation in Calliphora and Sarcophaga (Ribbert); 7. The con- trol of puffing in Drosophila hydei (Berendes); 8. Balbiani ring activities in Acricotopus lucidus (Panitz) The editor of this new volume of a successful series states in his preface that he has not aimed at completeness. The table of contents shows that this is so, but the contributors who have been selected are all recognized authorities in the field and have provided well-organized, well-written, and up-to-date re- views which nobody even remotely interested will want to miss. 232 The scope of most contributions is wider than the volume ti- tle suggests, and they will be read with profit by all those interested in chromosome structure and function, and in eukaryo- tic gene regulation generally. Contribution 1 has some striking electron micrographs of Drosophila chromosomes, while contribu- tion 6 devotes attention to the strict parallellism between puffing activity and cellular differentiation in "Kleinorgane" , the latter illustrated with electron and Nomarski interference micrographs . The book is beautifully produced and illustrated, but one wonders whether the luxurious production and the concomitant high price were really necessary, particularly in view of the absence of indexes. 119. B.EPHRUSSI. 1972. HYBRIDIZATION OF SOMATIC CELLS Princeton Univ. Press, Princeton. XII, 175 pp., 35 figs., 14 tabs., author and subject indexes. £ 4.75, $ 9.50 (cloth); £ 2.50, $ 4.95 (paper) This stimulating monograph is based on the text of three lec- tures given at Princeton University in January, 1971. The text has been somewhat extended and updated and 30 pages of notes were added, but the treatment is still highly selective. The resulting brevity makes the book very suitable for rapid orien- tation in this fascinating field, particularly for developmental biologists, because the author's main interest has always been in problems of cell differentiation. The book has a distinctly personal flavour; much attention is devoted to theoretical im- plications . The author was one of the pioneers in this area since it was opened up in I960. The first chapter presents an introduction into the principles of the cell fusion technique in the form of an historical account. The bulk of the book deals with its ap- plication to three areas of research: human genetics, cell dif- ferentiation, and cancer. The second area takes up almost half of the main text, i.e. three chapters, two of which bear the subtitles Reactivation of nuclei of differentiated cells in heterokaryons , and The fate of luxury functions in somatic hy- brids. In the latter the main theoretical preoccupation is with the stability of the determined (epigenetic) state of cells in vitro. The other two areas mentioned are treated much more briefly, that of cancer again chiefly in view of its possible implications for normal development. In bis concluding remarks the author touches upon much broader theoretical problems, such as the possible role of the cell membrane in differentiation and the cell theory generally. The book is attractively produced and well illustrated. 120. G.JAGERSTEN. 1972. EVOLUTION OF THE METAZOAN LIFE CYCLE, a com- prehensive theory Academic Press, London, etc. X,282 pp., 59 figs., author and subject indexes. £ 5.00, $ 15.50 This book is essentially a translation of a book first pub- lished in Swedish in 1968. It contains a new, comprehensive (but somewhat controversial) theory of metazoan evolution which has its starting point in the author's "bilaterogastraea" theory first expounded in 1955. Since then the author has carried out a number of necessary supplementary studies which are incorpo- rated into this text. The central thesis of the new theory is 233 that the life cycle original for all metazoan phyla comprises two phases, a pelagic larval and a benthic adult phase. This then leads to extensive discussions, particularly of Haeckel's "biogenetic law". The introductory chapter briefly discusses "primary larvae , "adultation", direct development, and "secondary larvae". The special section which follows occupies about three-quarters of the book and systematically examines the marine larvae of all metazoan phyla. The general section then discusses these data in 10 short chapters, the last two being devoted to the evi- dence for recapitulation in its modified and qualified sense. The book is well printed and illustrated with good, largely original line drawings. 121 . U.MITTWOCH. 1973. GENETICS OF SEX DIFFERENTIATION Academic Press, New York, etc. XIV,253pp., 40 figs., 6 tabs., author and subject indexes. $ 16.50 Contents: 1. Classical genetics of sex differentiation; 2. Genetics of continuous variation; 3. Aspects of the gene; 4. Heterochromatin; 5. The nature of sex differentiation with special reference to vertebrates; 6. Sex determination in man and other mammals; 7. Genes, chromosomes, growth, and sex This interesting book elaborates a thesis based primarily on recent findings of the author in mammals and birds. The thesis and its wider biological implications become clear from a quo- tation from the preface: The purpose of this book is to bring together evidence that the sex chromosomes may affect the rates at which cells di- vide and that the process of sex differentiation is based^on differences in growth rates during development .... [It] is hoped that the approach I have chosen - looking beyond the formal gene-phenotype relationship and emphasizing^ the dynam- ic relationship between chromosomes and growth - will lead to a better understanding of the role of chromosomes in the development of sexual and other characteristics, i.e., those which are basically of a quantitative nature. Although it must be admitted that the direct evidence for the thesis is still scarce, it is supported by much indirect evidence, partly from outside the area of sex differentiation itself, and this is expertly discussed in a series of concise but well-organized chapters. The theory of sex determination by Mendelian genes is dismissed, and much stress is placed on the non-genic heterochromatic chromosome regions and their reg- ulatory role in cell proliferation and growth generally, i.e. in a variety of plants and animals and in both sexual and non- sexual organs and phenomena. Thus the scope of the book is much wider than the title indicates. Symposium reports 122. B.I.CHERFAS, ed. 1972. GENETICS, SELECTION, AND HYBRIDIZATION OF FISH, translated from the Russian by R.Lavoott Israel Program for Scient. Translations, Jerusalem. VI, 269 pp., 34 figs., 62 tabs. This volume contains 28 papers presented at a Conference held in Leningrad in 1967. Although this is a long time ago, several of the papers may still be of interest to fish embryologists , 234 if only because they provide access to work performed and pub- lished in the USSR. We restrict our review to the papers which have some bearing on fish development. (The other papers deal with various theoretical and practical aspects of the genetics, cytology, and selection of fish and with some postembryonic characteristics of interspecific hybrids.) We mention first of all a review by Vanyakina (17 pp.) on the genetics of sex determination and on some problems of hormonal regulation of sex in teleosts, based mostly on non-Russian lit- erature. Papers by Smirnov (19 pp.) and by Makeeva (27 pp.) deal with developmental characteristics of salmon and carp hybrids, respectively. Both have good line drawings of hybrid embryos and fry. The other three papers in question are brief research re- ports on artificial gynogenesis in carp (Golovinskaya) , gonadal development and fertilization in grass carp (Bobrova), and the control of sex ratio by (visual?) feedback (Geodakyan and Koso- butskii). The titles of the Russian references are translated. 123. M.SUSSMAN, ed. 1972. MOLECULAR GENETICS AND DEVELOPMENTAL BIOLOGY Prentice-Hall, Englewood Cliffs. XII, 481 pp., 138 figs., 46 tabs. $ 12.00, £ 6.00 Contributors: Baltimore, Britten, Brown, Darnell, Edmonds, Gage, Gross, Halvorson, Miller, Mintz, Pardue, Roeder, Rutter, Sarkar, Sato, Stephens, Sussman, Tashjian, Thomas, Travers, Weiss, Woodland This book is of great interest because it provides an excel- lent "cross section" of the present state of our knowledge in an important area of frontier research. It is based on a Sym- posium held in September, 19715 but most contributions have clearly been updated prior to printing. The far greater majori- ty of the contributions are by American groups. Although not all contributions have a direct bearing on embryonic develop- ment, all of them are no doubt highly relevant to developmental regulation in a broad sense, and all are by outstanding experts. The 22 contributions range in length from about ten to over 30 pages, and deal with a great variety of systems. Almost all papers report on unpublished results, and many in addition con- tain concise, readable, and critical reviews of recent to very recent work. The papers are arranged in four sections, the contents of which can be briefly characterized as follows: I. The genomes of eukaryotic cells: molecular and developmental aspects (mode- rately repetitive DNA sequences; ring-shaped eukaryotic DNA; cytological nucleic acid hybridization; evolutionary model of gene expression in immunocytes; silk fibroin genes in Bombyx); II. Information flow from the genome to the cytoplasm and back (RNA polymerases in eukaryotes and in amphibian development specifically; ribosomal RNA synthesis in bacteria; electron microscopy of gene transcription; formation of mRNA in HeLa cells; poly-A sequences in RNA; RNA-dependent DNA polymerases); III. Programs for protein synthesis (yeast meiosis; Quantal control in Dictyostelium; embryonic neural retina; sea urchin cleavage; sea urchin cilia; cultured pituitary cells); IV. The inheritance of dif f erentiative capacity (Xenopus egg as an assay system; hepatoma cell hybrids; clonal differentiation in mammals; hormone-dependent ovarian cells in culture). The book is produced in offset print and adequately illus- trated. The photographs are well reproduced except for one or 235 two which have lost most of the detail. The book has no indexes and rather many printing errors. Reference works 124. R.C.KING. 1972. A DICTIONARY OF GENETICS. 2nd edit. Oxford Univ. Press, London, etc. VIII, 337 pp., many figs. £ 2.25, $ 4.95 (paper) This is the second edition of a book first published in 1968 (see review in Gen.Embryol. Inf .Serv. , vol.13, 1969, p. 312). Al- though it is a glossary rather than a dictionary, it is useful particularly for students who are beginning to read the primary genetical and related literature. In the new edition 700 new entries have been added, some ex- tant entries redefined, and some of the appendices updated. A flaw that has not been removed is the inconsistency and inac- curacy of many of the cross references. For instance, under "In- trachromosomal aberrations" the reader is referred to "Aberra- . tions", whence he is referred further to "Chromosomal aberra- tions". Under "Field" there is a reference to "Pattern", but the latter entry is absent. There are more similar examples. Some care should be devoted to this in future editions.

Utero-ovarian-fetal interrelationships (6); V. Ancillary hormonal and socio-behavioral influences on re- production (3) The reason why we briefly review this book is that almost all mammalian embryologists will at one time or another be confront- ed with problems of mammalian reproductive biology. The book presents a selective but well-integrated series of 25 critical and highly informative reviews of major areas in this field, written by 31 American and three European experts. Both basic and clinical aspects are considered. Perhaps understandably, not all chapters are equally up to date. The groups of chapters out- lined in the table of contents above are each preceded by an introduction by the editors which places the chapters in ques- tion in wider perspective. Chapters of particular interest to our readers are those by Bedford on sperm transport, capacitation and fertilization, by Baker on oogenesis and ovarian development, by Brinster on the nutrition and biochemistry of the developing zygote, by Glasser on the uterine environment in implantation and decidualization, and by Parks and Zimmer on immunological aspects of the fetal- maternal relationship. In the third and fifth of these most of the literature cited does not go beyond 1969. 236 Textbooks 126. C.R.AUSTIN and R.V. SHORT, eds. 1972. GERM CELLS AND FERTILIZA- TION Cambridge Univ.

Book 2 of the series was reviewed in this issue under no. 34. All that was said there applies to the present volume. The illus- trations by Fuller are of unsurpassable quality; those based on electron micrographs are stunningly realistic. Monographs 127. A.S.GINZBURG. 1972. FERTILIZATION IN FISHES AND THE PROBLEM OF POLYSPERMY, translated from the Russian by Z.Blake Israel Program for Scient. Translations, Jerusalem. VIII, 366 pp., 68 figs., 14 pis., 38 tabs. $ 25.00, £ 11.73 Contents: 1. The egg; 2. The spermatozoon; 3. Gametic associ- ation; 4. Number of spermatozoa penetrating egg and fate of supernumerary spermatozoa; 5. The cortical reaction in physi- ologically monospermic eggs of fishes and other animals; 6. The mechanism of the block to polyspermy This is an unchanged translation of a book first published in Russian in 1968; it is the first comprehensive review of fer- tilization patterns in relation to the problem of polyspermy, with special reference to fishes. The author has worked in this area for many years and has incorporated many of her own re- search findings. Morphological, ultrastructural , and physio- logical aspects are extensively discussed. The first two chapters each have a general and a comparative section, both restricted to fishes. Ch.3 is a general discus- sion of sperm-egg interaction and of the various hypotheses proposed to explain it. Ch.4 is largely comparative and deals first with fishes and then, more briefly, with invertebrates and chordates other than fishes. Ch.5 is likewise comparative. Finally, ch.6 suggests a one-step mechanism for the block to polyspermy based on the discharge of cortical granules and al- veoli, which is discussed with special reference to fishes and sea urchins. The book is produced in offset print. Most of the photogra- phic illustrations are brought together in plates at the end of the book; unfortunately all have suffered badly from reproduc- tion. The bibliography has more than 1,300 entries; about 250 of these are Russian titles (with English translations). The book has no indexes. 237 128. H.W.MOSSMAN and K.L.DUKE. 1973. COMPARATIVE MORPHOLOGY OF THE MAMMALIAN OVARY Univ. of Wisconsin Press, Madison, etc. XXVIII, 461 pp., 198 figs., 9 tabs., combined subject and taxonomic index. $ 25.00 Contents: 1. Gross anatomy of the mammalian ovary; 2. General microscopic structure of the mammalian ovary; 3. Development of the mammalian ovary; 4. Morphology and cyclic changes of a representative mammalian ovary; 5. The human ovary; 6. Compar- ative morphology of specific ovarian tissues and structures; 7. Features and problems associated with the mammalian ovary; 8. Retrospect and prospect This scholarly monograph was written by two eminent experts and embodies much of their unpublished material gathered in the course of several decades. They state in their preface that one of the purposes of the book is "to reduce the misunderstanding and misinformation regarding the mammalian ovary which one en- counters on every hand". In so far as this is due to the fact that most people's knowledge is restricted to a few common lab- oratory mammals and man, the broadly comparative approach taken here is particularly valuable. The first three chapters present the necessary background in a relatively straightforward manner, though in more detail than is usually found in textbooks. In ch.4 the red squirrel, Tamia- sciurus hudsonicus, is adopted as a sort of "type species", while ch.5 follows a similar pattern for the discussion of the human ovary. Ch.6 then takes up the comparative approach in more detail; it is in part a synthesis of the extensive informa- tion presented in taxonomic order in the form of synoptic tables and supplementary notes in the 100-page appendix. A subject which was intentionally omitted is the cytology, cytogenesis, and cytolysis of ova. Subjects of particular interest to embryologists discussed in ch.7 are the origin of oogonia, ovarian regeneration, natural superovulation, intra-ovarian parthenogenesis, and induction and metaplasia in the ovary. Ch.8 contains a schematic summary of the authors' concepts of the developmental origin of the major components of the mammalian ovary. The book is well produced and profusely illustrated, mainly with very good photomicrographs. It has a useful glossary and a 36-page bibliography. 129. A.F.TURDAKOV. 1972.

X,266 pp., 84 figs., 10 pis., 13 tabs., author index. £ 7.30 Invertebrate endocrinology has been a speciality of French zoologists for a long time. This collection of reviews contains 238 contributions from eight leading investigators in this field, six French, one Belgian, and one Japanese. The reviews are ex- tensive, well illustrated and up to date, and deal with gonado- genesis, gametogenesis, and gamete maturation in different com- binations, particularly from an endocrinological viewpoint. The taxonomic groups considered are the following: hydrozoans (Brien); polychaetes (Durchon); gastropods (Streiff); higher crustaceans (Charniaux-Cotton) ; isopods (Legrand and Juchault); insects, especially Lampyris noctiluca (Naisse); echinoderms, particularly Asteroidea (Kanatani). The book provides a good entry into the relevant literature in French and would merit to be translated into English. It is well produced but the price is rather high. 131. L.ZAMBONI. 1971. FINE MORPHOLOGY OF MAMMALIAN FERTILIZATION Harper & Row, New York, etc. XVI, 224 pp., 99 figs., subject index. $ 15.00, DM 55.50 In this atlas the author, a pathologist who has been active in this field for years, has attempted to illustrate the most fundamental events of gametogenesis and fertilization in mam- mals and man, from the mitotic division of the spermatogonium and the resting primary oocyte till the first cleavage divi- sion of the embryo. The atlas consists of 132 good electron and light micro- graphs, combined into 99 full-page plates; 54 figures are of human, 74 of mouse, and 4 of rabbit material. The story told by the plates is very complete indeed, and considers all the essential normal aspects as well as some findings of rare or pathological occurrence. The appearance of the gametes at all stages during their migration through the male and female gen- ital tracts is illustrated. Each plate has an average of about half a page of text, usu- ally with several references. The text is clear and authorita- tive, and frequent cross-references to other plates are pro- vided. The figures are labelled well though perhaps somewhat sparsely. Once an arrow is left unexplained; another arrow mentioned in the text is absent. Most of the electron micrographs look rather grey and in some cases there is loss of information through lack of con- trast. It is difficult to judge whether this is due to prepara- tory or photographic techniques or to reproduction. Otherwise the book is beautifully produced at a very reasonable price.

This book contains the papers read and the discussions held at a Symposium sponsored by the I .S.D.B., held in August, 1971 in Edinburgh. The book is not commercially available; a limited number of copies are obtainable on application from the Librar- ian, Department of Genetics, University of Edinburgh, U.K.; the lay-out of the articles suggests that reprints are available from the authors. The Symposium had about 40 participants from all over the world, including five from Eastern-European coun- tries . 239 Most papers are a mixture of review and research report, and all have up-to-date reference lists. The data discussed relate to the whole animal kingdom, with emphasis on man, mammals, and Drosophila. The 27 papers are grouped in seven sections. We men- tion these below, singling out in brackets those contributions that we feel are of particular significance to our readers: Sperm structure and development (3 papers; Fawcett on cell differentiation and organelle continuity in spermatogenesis; Bedford et al. on post-meiotic changes in the nucleus and mem- branes of mammalian spermatozoa); Sperm metabolism and function (Moore on RNA polymerase during mammalian spermatogenesis); Phe- nogenetics of spermatozoa (5 papers); Immunogenetics of sperma- tozoa (3 papers); Segregation distortion (8 papers; among other things, discussions of possible haploid gene action); Determina- tion of germ cell sex (McLaren on germ cell differentiation in mouse chimaeras; Short on germ cell sex); Effect of chromosomes on germ cell development and function (4 papers; Meyer on the influence of the Y chromosome on fertility and phenotype of Drosophila spermatozoa). The book is exceedingly well produced and beautifully illus- trated, mainly with photo- and electron micrographs. It has no indexes . 133. J.D.BIGGERS and A.W.SCHUETZ, eds . 1972. OOGENESIS Univ.

According to the prologue "Its purpose was to provide an up-to-date account of oogene- sis in the several areas, and to encourage the exchange of ideas between the scientists involved in the three main areas of study [meiosis, developmental aspects, endocrine regula- tion] . Major emphasis is given to the comparative approach, and to aspects of oogenesis not generally considered. The topics were chosen to stress the viewpoint that oogenesis is a major segment in the continuum of life, and that the oocyte is specialized by a process of differentiation to (1) undergo meiosis, (2) participate in cell fusion, and (3) accumulate and provide materials which govern the nature and nurture of the new individual produced when the ovum is fertilized." The large majority of the 25 contributions are complete and usually long reviews. Taken together they contain almost all the recent information on oogenesis in easily surveyable form (with emphasis on the vertebrates), so that the book is a valu- able reference source. The book is handsomely produced in offset print, resulting in a reasonable price. The numerous excellent photo- and electron micrographs are reproduced with great care. 240 132*. K.S.MOGHISSI and E.

All but one of the 21 contribu- tors were Americans. Although the main preoccupation was with possible contraceptive applications, many of the contributions will be of interest to mammalian embryologists generally. Most papers range in length from about 15 to 30 pages, all are sur- veys of original research that was recent to very recent at the time of writing, and several have very long bibliographies (which however do not go much beyond 1970). No discussions are recorded. The 16 contributions are arranged in three sections dealing with sperm capacitation, fertilization, and implantation respec- tively. The first section will not be considered here. Papers in the other two sections that are of particular interest to our readers are the following: Brackett et al. on rabbit and human fertilization in vitro; Stambaugh on acrosomal enzymes; Zamboni on fertilization in the mouse (50 pp.); Edwards on hu- man fertilization and cleavage in vitro; Hafez on differentia- tion of the blastocyst (47 pp.); Mintz pon an implantation fac- tor from mouse uterus; Boving on blastocyst spacing and orienta- tion in the rabbit; Laurence on immunological studies of nida- tion. The book is well produced and profusely illustrated. The numerous photo- and electron micrographs are well reproduced. 135. S.J.SEGAL, R.CROZIER, Ph . A . CORFMAN, and P .G .CONDLIFFE , eds. 1973.

XXIV, 586 pp., 202 figs., 91 tabs., subject index. $ 44.50 This volume embodies the proceedings of a Conference held in Bethesda, Md . in September, 1970. Consequently, the publication has taken more than two years, which detracts from the topical- ity of the book. The Conference had more than 130 participants from 23 countries throughout the world. The 39 papers and their discussions are grouped into six sections as follows: 1. Regulation of pituitary function (7 papers); 2. Regulation of sperm production (6); 3. Fertilizing capacity of spermatozoa (6); 4. Biology of the mammalian ovum (4); 5. Tubal transport of gametes (6); 6. Corpus luteum func- tion (10). Section 4 has papers by Biggers on oogenesis and ovum maturation, by Graham on nucleic acid metabolism during early mammalian development, by Brinster on protein synthesis and enzyme constitution of the preimplantation mammalian embryo, and by McLaren on blastocyst activation. In sections 1, 2, and 5 almost all papers are of potential interest to mammalian em- bryologists. The book is concluded by 30 pages of general dis- cussion which contain several original contributions, complete with illustrative and tabular material. Most of these centre around endocrinology and male contraception. A conference sum- mary of nine pages is provided by Diczfalusy. The book is beautifully produced and illustrated, but one won- ders whether a less luxurious production resulting in a lower price could not have made the book accessible to more potential users . 241 Books of readings 136.

MSS SERIES OF BOOKS OF READINGS MSS Information Gorporation, 19 East 48th Street, New York, N.Y. 10017, U.S.A. This new series was started in 1972 and is by now quite exten- sive. Volumes having a bearing on developmental biology which were at our disposal have been briefly characterized under the appropriate headings (see author index, entry MSS). The editor or editors of the series are anonymous, and no 242 justification of the choice of papers is given in the brief anonymous volume prefaces. This makes it difficult for the re- viewer to judge whether the choice is authoritative in areas with which he is not familiar. In those areas where he feels more competent to judge he often found it difficult to agree with the inclusion of certain papers and the omission of others. However, this holds for almost all selections of this kind. A remark that holds for the series as a whole is that some areas are covered much more extensively than others. In some areas, but not in all, there seems to be some bias towards American publications, which may be due in part to the under- standable restriction to papers written in English. The books could be useful in graduate courses, but in any particular case this strongly depends on whether one agrees with the selection and extent of coverage. Many teachers may prefer to make their own selections. Most papers are from well-known and easily accessible jour- nals. The papers are reprinted in fascimile, but for some rea- son abstracts and summaries have usually been removed, as well as authors' addresses. The text is on the whole clearly printed, but the photographic illustrations have suffered from reproduc- tion to varying degrees, sometimes to the extent of losing most of their information content. Each volume has indexes to authors and title key-words of the papers included. The tables of con- tents and the credits and acknowledgements show signs of hasty composition and careless proof-reading. The books are sturdily bound, but the price per volume is too high for the value one gets. The use of the name of the first author of the first paper on the back, where the editor's name should be, is highly misleading. One of the volumes at our dis- posal contains 16 wrong pages (see review no. 45). Reference works 140. Ph.L.ALTMAN and D.S.DITTMER, eds . 1972. BIOLOGY DATA BOOK, 2nd edit. Vol.1 Fed. of Am.

Genetics and cytology; II. Reproduction; III. Development and growth; IV. Properties of biological substances; V. Materials and methods; Appendix I-IX The second edition of this book, which was first published in 1964, has been greatly expanded, and now appears in three vol- umes totalling more than 1,600 pages (as against 633 for the first edition). The expansion has resulted in part from the in- clusion of material from the specialized handbooks previously published in the same series. In addition many more species were covered. Vol.1 is based on contributions made by 245 research scien- tists in the capacity of primary contributors or reviewers. Part III, which is of most immediate interest to our readers, was expanded from 40 to 74 pages. Among the new sections are: time variations in developmental stages of mammals and birds; equivalent numerical designations for stageing systems in am- phibians and fishes; normal stages for Ambystoma maculatum; liver regeneration in the rat; limb regeneration in newts. Human postnatal growth data are now in a separate chapter. Nor- mal stages for the mouse and for Xenopus laevis are lacking; 243 their inclusion in later editions should be considered. The information in part II is biological rather than physiol- ogical, but there is much of interest there for embryologists : gestation and incubation times, modes of fertilization and de- velopment, breeding seasons, etc. (for both vertebrates and invertebrates ) . Two new appendixes have been added: a listing of scientific names with corresponding common names, and the converse. The classification outline for living animals and plants has been considerably modified for several phyla. Vols. II and III will appear in 1973 and 197^, respectively. The books are produced with great care and are extensively indexed. 244 MBL WHOI LIBRARY UH IBbb U
