Allan Banctt, et al., Westinghouse Research Lahoratories. Walker and Co., New Ynrk, 1965. 2 3 i pp. Figs. and tables. 16.5 X 24 em. 85.95. Now that "transistor" is part of the vocabulary of every child, and "solid state" is an advertising slogan for phonograph amplifiers, it is obvious that crystallography is well established in our industrial technology. But it is not so obvious that it is well established in our educational system. Some of the important principles of crystalline properties have been known for a very long time, hut they have not been taught very well in elementary courses in chemistry or physics. Some other aspects of solid state phenomena. were discovered only recently. Same of the electrical effects in slightly impure semiconductors me finding industrial application faster than they are finding academic acceptance. "Crystals: Perfect and Imperfect" is one of several recent books which seem to he the result of impatience with this state of affairs. The authors, all scientists associated with the Westinghouse Research Laboratories, are infected with enthusiasm for the beauty of crystals as such, for the elegant mathematical description of their symmetries, and for the practical applieations of some of their curious orooerties.

science and engineering. It is just as suitable for teachers of elementam science

forms of crystals are discussed in terms of assemblies of unit cells, and the simple ideas of symmetry are presented. In the next chapter the idea of the space group is developed, and the consequences with respect to symmetry of physical properties are explained. Some examples of actual atomic structures within the unit cell are described. Dislocstions, twinning, and some other k i d s of imperfections are described in considerable detail. Three chapters are devoted to crystal growth, with emphasis an the role of imperfections in growth. Some actual industrial processes are described for preparation of large single crystals and for the final fabrication into transistors. Two final chapters are devoted to diffraction methods for study of crystal structure and the nature of thermal vibrations in crystals. The book is filled with attractive and instructive illustrations. The text is clearly written a t a. level whioh would be understood (with the exception of a few pages) by almost any bright high school student who is not frightened by 8. few strange words. On pp. 58-60 the ideas of the vector and tensor are introduced very naturally. Only in thelast chapter is mathematical notation likely to be any barrier to understanding. One may s u s

The title of this small volume is grossly misleading, hut, if a genuine practicing "nuclear chemist" like Dr. Harvey wishes to use it, who is to deny him? I t is certainly not unfair to say that there is absolutely no chemistry in the book. I t is, rather, a highly readable introduction to nuclear physics written by a specialist whose background in chemistry and nuclear physics research makes him an excellent choice to author such a hook for consumption by budding chemists. The author's awareness of limitation- in the background of undergraduate chemistry majors has, presumably, led him to attempt to do the job from the ground up and to employ analogies to chemical terms, such as, for example, bond energy and heats of reaction, from time to time. A tremendous amount of material is covered and none of it is trivial. Nevertheless, the author manages to convey a feeling of excitement and a sense of the richness and power of the principal constructs of nuclear research from the experimentalist's point of view. The table of contents reads much like those of Choppin's "Nuclei and Radioactivity" and Overman's "Basic Concepts of Nuclear Chemistry," but there is more information and consistently more detailed attention to interpretation and prediction of values of nuclear properties in Harvey's hook. The author will succeed in rationalizing nuclear systematics for the reader who has gone beyond freshman chemistry and physics by means of arguments and constructs which are not entirely foreign to the typical undergraduate chemkt's experience. In addition, an introduction to the physicist's approach to nudear reaction probabilities should be vduable to young chemists who will be devoting progressively more attention to chemical reactions in molecular beams in the future.

Although there are some exceptions, introductory and intermediate level treae ment of the chemistry of the solid state has been somewhat neglected in books published in this country. Thus this monograph in the Oldbourne Chemistry Series is a partimlarly welwme and needed work. I t might seem a t first surprising that somewhat less than half the book is devoted speoificdly to a disoussion of the properties of the allotropic forms of the elements. However, the author has wisely seen fit to lay the foundations in thermodynamics, chemical bonding, and crystal structure and then to use these concepts widely in the descriptive part. Chapter one (26 pages) begins with an introduction which provides some useful definitions snd distinctions and a rather brief treatment of experimental methods. There follows a, thorough discussion of the phase rule and its applications to systems of one component and s. development of the thermodynamio aspects of allotropy. The chapter concludes with a detailed consideration of the mechanism of allotropic transform* tions which includes a brief discussion of martensitic transformations. Chapter two (27 pages) deals with chemical bonding. A brief, but lucid, presentation of the electronic theory of the atom and of the periodic table is followed by a discussion of chemical bonding under the subheadings of diatomic molecules, polyatomic molecules with localized orbitals, polyatomic molecules with delocali~edorbitals, and some molecules of an intermediate nature (e.g., amne). The perspective is principally that of molecular orbital theory and band theory. The third chapter (16 pages) is concerned with orystal structure. Metal structures are discussed with particular emphasis on the close-packed (hexagonal and cubic) and body-centered cubic types and their inter-relrttionships. The structures of the nonmetals are first related to their electronic configurations; then follows a description of the zinc blende and sodium chloride structures and examples of nonmetal structures arising from each. The chapter concludes with a consideration of the interrelationship of the polymeric structures of the elements of Groups IV, V, and VI. Chapter four (50 pages) is a systematic presentation of the properties of the allotropic elements. The organization is socording to electronic configuration. Although the information given is quite spec5c and some workers' names are given, the only references are the twelve given in the appendix as Suggested Further Reading. Any reader of such a book will wish that the author h d treated some particular points in greater depth or may koow of some more recent work on a ~peciGcitem that had not come to the author's attention.

In another instrtnce, the author states (p. 75) that iron "has never been obtained in the stable form of its cogeners ruthenium and osmium, i.e., hexaguud close-peeked," hut this farm of iron has been reported recently as being obtained a t very high pressures (T. Takahashi and W. A. Basset, Sciace, 145,483-6 [1964]). Chapter five (five pages) gives a brief account of variant forms of gaseous elements, particular attention being given ortho and para hydrogen and active nitrogen. On the whole, the book is quite carefully and lucidly written, the figures me easily understood, and the index is very good. This work would be quite well suited for supplementary reading in an upper division c o m e in inorganic chemistry and could possibly be used in the same manner in some high-level general chemistry courses. Thns any minor defeote noted above should not unduly detract from what is an excellent monograph, one well worth adding to a personal or institutional library. CLIFFORD E.

This is the most comprehensive book on photochemistry yet to appear. All areas of photochemistry excepting photobiology are covered in this book. The authors have produced afull account of our present knowledge of the photochemistry of organic and inorganic compounds in the gaseons phase and in the solution phase. The work reviews thousands of references and therefore also serves as a valuable source of bibliography on the subject. The book is self-contained in that it oontaina a detailed review in the first four chapters of the physical problems asso-' ciated with photochemistry, notsbly the quantum mechanics of electronically excited states of molecules. This is followed by a treatment of the photochemistry of polyrttomic molecules, and then follows two chapters on rate mechanisms in photochemical reactions. The final c h a p ter is a modern account of experimental methods in photochemistry including the newer light sources and acthometry. There are also useful appendixes including tsbles of dissociation energies and pertinent thermocbemical data. Professors Calvert and Pitts are to be congratulated for their excellent book. It represents a great service to the field of photochemistry. This book will, no

This is a most stimulating and informative book, much more so than the stark simplicity of the title indioates. Its aim is to draw together the two related fields of solution studies of synthetic and natural mmacromolecules and to show how they complement and reinforce each other. At the end, it suggests, through a survey of association phenomena, and reactivity of polymers in solution, that it should be possible to make synthetic systems designed to imitate eneymes in their reactivity toward specific molecules or chemical processes. Professor Mar* wetz succeeds in his objective very well and shows many fruitful opportunities for cross fertilhation between the two fields. Although the relation between natural and synthetic polymers has heen a.subject of speculation for a long time, Morawetz points out that two developments of the last decade, now make it reasonable to resurvey the two areas as they relate to each other. First, Ziegler and Natta demonstrated that regularity of structure is not solely a property of natural polymers. Instead great wntrol can be exercised over the details of the structure of synthetic polymers. Thus, for example, synthetic "natural rubber," which closely duplicates natural rubber, can now be made after many fruitless earlier attempts. Second, the evistence of both natural and synthetic polymers in regular helical wnfigurations in solution demonstrates transfer of observed behavior between the two divisions. The original studies of helical structures in natural systems have been more and mare helpful in e x p l s i ~ n gaspects of the behavior of iynthetic materials. I t seems most reasonable that further similar interactions will be utilized. The book is designed for the reader who has some familiarity with polymer science as applied to synthetic macromolecules, but not necessarily an advanced understanding of the theories describing the behavior of polymers in solution. I t will be useful to graduate students, teachers of polymer ohernistry, and researchers in the area who want to have an authoritative sunrey of one of theimportantpt~rts of polymer science. The subjects include: thermodynamics of solutions, configurations of long chain molecules, dilute solution properties, interactions of polymeric solutions with radiation, polyelectrolytes, associations with macromolecules, and chemical reactions as affectedb y the presence of polymer (Cmtinued on page A.912)

There is a wealth or even a plethora of books on beginning chemistry designed to aid the student hut only a limited amount of material aimed directly at the teacher. These volumes are a welcome addition to the second category. They present demonstration experiments rather than exercises to be carried out by the students. Part I contains more than 4W such experiments dealing with the chemistry of the nonmetals; Part I1 offers 270 experiments involving the chemistry of the metals. The volumes are plentifully supplied with excellent line drawings of the set.ups. In the foreword, the author paints out the advantages d demonstrtttian experiments. Many experiments require considerable experimental skill and facility in the handling of apparatus and chemicals and hence can be conducted by ineuperienced students only with much difficulty. If such an experiment is assigned to students, their attention is devoted almost entirely to the manual manipulations with neglect of the real objective.

Those instructors who can read simple German will find in these two volumes much that is of value. The experiments are described in detail; the chemicals and equipment required are carefully listed; the underlying ohemistry adequately die cussed. The whole gamut of general introductory chemistry is covered ineluding chemical technical processes. Qualitative and quantitative procedures are like wise illustrated. The diagrams are drawn with care and help greatly when using the books. I n short, the reviewer is enthusiastic about these aids to the teacher; they deserve a wide circulation. The prices given above are in East German marks. I t is not phssible always to translate these into dollam but in general they may be taken as equivalent to the West German mark (25 cents). When ordering it might be well to inquire into this point to avoid unpleasant misunderstandings. RALPHE. OESPER Uniuersity of Cincinnati Cincinnati, Ohio (Continued on page A916)

A good review article is an acceptable method for information rebrieval. A superior review article not only retrieves hut also selects and evaluates the liter* ture. Only the expert can do these thin- well. The individual scientist, especially the investigaior in a new area, is becoming more and more dependent on the expert for thesefunctions. I t is a pleasure to describe a hook where many authorities have selected and evaluated the literature in the important area of hioehemical separations. James and Morris, the editors of this book, were fortunate in obtaining contributions from distinguished scientists in Australia, England, Germany, Sweden, Switzerland, and the United States. Their contributions include five chapters on gas-liquid chromatography, two c h a p t e n on gel filtration, nine chapters on paper and fhin-layer chromatography and one chapter on counter-current distribution. The editors have emphasized lipid separations, and lipids, steroids and bile acids are discussed in 12 of the 17 chapters. The book contains many examples of the fact that lipid chemistry and metabolism are now among the most exciting areas of biochemical research. The reviews on g d q u i d chramstography contain discussions about radioactive compounds (A. T. James), the separation and identification of steroids, alkaloids, and sugars (E. C. Horning and W. J. A. VandenHeuvel), coenzyme A (M. G. Horning), bile acids (J. Sjowll), and amino acids (A. Karnen and H. A. Saroff). The frsetionation of proteins, peptides and amino acids (B. Gelotte) and polysaceharides (K. Granath) are described in the chapters on gel fltration. Paper and thin-layer chromatographic methods are outlined for the separation of protein hydrolysates and amino acids (M. Bremmer, A. Niederwieser and G. Pataki), alkaloids (D. Waldi), steroids (R. Tschesche, G. Wdff and K. H. Rich(R. ert), triterpenoid compounds Tschesche, I. Duphorn and G. Snateke), and bile acids (A. F. Hofmann). Hofmann has also written a chapter on hydroxyrtpatite as an adsorbent. L. J.

"Seiverd's Chemistry for Medical Technologists" has been rewritten by White and Frankel without changing the character of the first edition. (See THIS JOURNAL, 36, 421 [August, 19591.) Some newer methods have been added, e.g., blood pH and pCOl, Eame photometry, enzymes, PBI, and a chapter on quality mntral, as well as a. good section on osmometry. The book, however, has not gone beyond a rather complete collection of techniques suitable for the student laboratory. This attempt in itself deserves credit, since some teaching hosDATIDG.

No or insufficient mention has been made why a particular metbod has been selected and some of its advant,ages or limitations over obher techniques. In the chapters on blood pH and pCOl the close interdependence of these two components has not been explained, nor has there been a short descripbion of the gas laws, governing the determination of a gas like CO. by the Van Blyke technique. Not even s. litemtnre reference has been cited. The authors have intentionally omitted the exciting development of automation going on in the clinical chemistry lsboratory during the last decade. The reviewer would have had mme understanding for not treating this subject thoroughly, since automation is still in t,he stage of development. The complete omission of antomation and semiautoma tion certainly makes the book less nsefid as review material for the practicing medical t,echnologists. The very nature of s, manual makes its value vary from laboratory to laboratory and its usefulness is short lived. Therefore, a price redurton should be attempted by publishing a paper-back issue.
