book reviews cloning, and division and fusion. The second new ehzpter is devoted to antibody synthesis and includes discussions on the origin of antibody chains, specificity, site of antibody synthesis, and immunological tolerance, among other topics. The text is easily readable and is well illustrated. It contains a glossary of terms often encountered in molecnlar biology, thus making it very useful for the beginning student. Each chapter contains a list of general references which further increase the usefulness of the hook. In summary, the second edition of "Molecular Biology of the Gene" is an excellent attempt to present the newest topics in the emerging area of molecular biology, and in related areas, in an easyto-read and easy-ta-understand format. I t would be a valusblble addition to the library of any individual interested in these areas. CHARLESL. BORDERS, JR. The College of Wooster Wooder, Ohio 44681

Few sufferers from dental caries realize the complexity of the processes involved in its production. Each individual carious lesion represents an individual event. This is so because caries results from the interaction of the surface of a. tooth whose farm and composition were determined by the metabolic state of the bearer of the tooth a t the time of its formation with the particular fluids, foods, and bacteria present in the mouth at the time the lesion forms. Dietary factors while the toothis forming are thus of importance, since they determine the chemical composition and morphological structure of the tooth. Even more important are the local factors a t the tooth surface when the attack begins. These factors are the subject of this book. I t contains the papers presented a t a symposium held in 1966, hut they have been updated to early or mid-1970 and therefore present rtn excellent overview of the present state of this field. The authors are all authorities in their subjects. The papers discuss the effects of types of foods, vitamins, antibiotics, organic compounds, fluorides, calcium, phosphorus, and various trace minerals. all factors which have been shown either to reduce or increase the amount of caries or the rate of its production. The emphasis throughout is on the chemistry and biochemistry of the pracesses considered. The book serves as an excellent introduction to and general picture of the subject for a non-dental

Physics Demonstration Volumes I and 11

Experiments.

Edited by Harry F. Meinera. The Ronald Press Co., New York, 1970. 1493 pp. Figs. and tables. 28 X 21 cm. $30. Editor Meiners, owdirector Robert Resnick, a committee of six physicists and a considerable staff have produced a work that is encyclopaedic both in scope and in physical dimensions. The major part comprises over 1200 journal-sized pages describing s multitude of demonstrations involving concepts drawn from all areas of physics and of widely varying degrees of sophistication. The apparatus needed ranges from (literally) household csst-offs to some requiring s. considerable amount of careful construction. Full details for the fabrication of the mare complicated devices are provided, wisely, as an appendix. In compiling these volumes, the editor visited over 100 institutions in the USA, and others overseas. The existing literature and commercial equipment was surveyed. Given the comprehensive nature of the work, one imagines thst any teacher who uses physics demonstrations for classes at any level will want to have a copy available. Some lecturers will use these demonstrations a7 a point of departure for their own ingenious modifications. Others of us will be glad enough to have the kind of cook book we would not prescribe for our students. Even the latter group has an outlet far the imagination, however, for each demonstrittion must be integrated into the rest of the presentation. The teacher must find wavs to brine out rhc ron..rl.rs the exprriment is suppoivd to illuitrnlr liwe the dewripti, n- d !he euperlment>l u r e little toaby In.1 the bmrk opens with a series of essays directed to the purposes and methods of the lecture demonstration. This section presents many stimulating suggestions and by no means a unified point of view. Eric Rogers, in a careful discussion d different goals for demonstrations suggests the value of same experiments simple enough to be taken home. Gerald Holton, also advocating a departure from the "special" nature of most demonstration equipment, suggests the occasional showing of real, working research apparatus, even though the hesio physical concepts may not be so readily exposed. Sir Lawrence Bragg describes the long tradition at the Royal Institution of very carefully prepared lectures using special demonstrations built by a highly skilled staff.

The book is completed by s. series of essays on special techniques such as films, closed circuit television, shadow and overhead projection and stroboscopio effects. These articles and those on purposes should have an interest far beyond the physics community. Two quibbles might he made. I t was decided to omit experiments described in an earlier A. A. P . T. compilation, "Demonstrstion Experiments in Physics" (R. M. Sutton, editor; McGraw-Hill, New York, 1938) unless "significant modifications were made since publication in 1938." Since Sutton's book is now out of print same experiments of interest (perhaps the simplest have aged best) will not be avsilable to many readers. Components have often been specified as the particulsr product used by the institution that developed the apparatus. In the case of experiments designed overseas that usudly means products which may be difficult or impossible for an American purchsser to obtain. Such readers would find a designation of s. suitable domestic product very helpful. The experiments me illustrated by photographs and line drawings. It appears thst these and the instructions are clear and complete enough to enable the teacher to reproduce the equipment. That particular pudding, however, this reviewer has not yet had time to prove. These two volumes will doubtless prove indispensible to the physics teacher. Chemists will find the general essays and the experiments in the Heat and Atomic Physics sections of interest and use. Perhaps they will also take to their armchairs, leaf through the volumes and enjoy the enduring aesthetic appeal of a. neat experiment. CHRISTOPHER L.

(48. A118, Recently THIS JOURNAL (1971)) carried a review of Elizabeth Patterson's "John Dalton and the Atomic Theory" (1970), whose title is practically identical with that of the book presently under review. Obviously these books duplicate much of the material but in the broad sense they supplement each other sinoe the Patterson book deals with the human side of Dalton predominantly, whereas the somewhat older Greenaway volume stresses pmticularly the chemical and philosophical sspects of his achievements. However, Greenaway in 1958-59 had already published "The Biographical Approach to John Dalton" and obviously saw no need to repeat himself unduly. The Prtttersan hook was directed at the general reader while Greenaway was in (Catinued a page A788)

book reviews this later volume concerned with reaching the mature student of chemical history. I t is highly recommended that both hooks he avsilable. When discussing the various facets of Dalton's work, Greenaway does not hesitate to delve into the genesis and history of the matter at hand. This broad viewpoint makes this treatment all the more valuable. Furthermore this writer has gathered in the Notes and References the bibliographieal sources of his discussions, a feature thst will spped to the serious reader. If one wishes to get behind the scene, so to speak, this is the book to have st hand. Dalton, for reasons that Greenaway makes apparent, is far more appreciated now than he was during his lifetime; his work was not always understood by his contemporaries. The author traces in detail how Dalton's theories aided immensely in the formation of later laws in s. number of fields and though modern developments in the ideas regarding the structure of the atom have now superseded his primitive notions, the history of these developments is of prime importance. This fine book will not go out of date and will bear frequent rereading.

Hellmtd Fiedlw. 7th revised ed. Verlag Chemie, Weinheim Bergstrasse, West Germany, 1970. 367 pp. Figs. and tables. 17 X 24 cm. DM 19.80 ( I mark = 27.3 cents). This excellent book, which has gone through numerous revisions, desk with the various aspects of chemical calculations, a field that sometimes seems difficult to beginners when it is not presented in a clear logical fashion. Even the more advanced student will find here helpful hints, and many teachers will welcome not only the clear presentations hut also the many problems (with their answers) that can be used when constructing quizzes and home assignments. There are 400 fully worked-out problems incorporated in the text plus 218 practice problems whose answers are given at theend of the volume. The 28 illustrations are of muchvalue. The subject matter is covered in 50 sections, which extend from simple arithmetical rules, plane and solid geometry, to topics of immediate interest to the chemist. Typical subject headings are: densities, logarithmic calculations, slide rule, mixing rules, molecular masses of gaseous elements, percentage compositions, chemical reactions, conversion of percentages into mole percents, volumetric and gravimetric analyses, gas laws and gas analysis, viscosity, electrical units,

The principal author, Louis De Vries, is well known in the chemical world for his widely used "German-English Technical and Engineering Dictionary" (1950). He and his team have recognized the fact that the language of chemistry, chemical engineering, and allied fields is subject to accretions which require that dictionaries be kept in step with the chrtnges. This obvious need has been kept in mind in the present instance and s. month's trial in actual translating practice has demonstrated to this reviewer the value of having at hand an upto-date German/English dictionary complied by experts in both the scientific and the.linguistie fields. The Foreword states that due attention has been given in the choice of the included vocabulsry not only to the organic, inorganic, physical, pharmaceuticrtl, and electrochemical fields but also to physics, biology, medicine, mathematics, mineralogy, and crystallography. Furthermore, words have been selected from recent literature an such topics as biochemistry, physiology, macrohiology, biophysics, atomic physics, spectroscopy, stereoehemistry, reactor technology, and electronics "thus enabling the user to cope with the more specialized problems of translation.. . . I n the compilation of this dictionary the authors have searched through a wide range of technical literature and consulted numerous German/ English and English/German dictionaries." In short no effort has been spared to produce an extremely useful trsnslation aid that will he of much value to workers in a wide variety of fields. The words are printed in two columns per page; the German in bold face and its translation(s) in 10-point type. About 100 wards (and their English equivalents) appear on each page so that roughly 7000 words have been provided here with their English translations. The hook is
