a highly physical framework. They have gone further, and have used the physical concepts very effectively to interpret and organize the factual material and thereby to make it unusually meaningful. The book, successful as i t is in its descriptive chemistry, definitely suffers from other shortcomings which, in this writer's opinion, partially vitiate its utility. As I examined and read the hook, my initial enthusiasm slowly gave way to doubts and questions. I t might be said t h s t the book's strongest points are its broad conception and motive, that its organization is somewhat weaker, and that i t falls shortest in the details of its execution. The choice of topics is excellent; the interpretations based on energy and momenta, distribution functions, thermodynamic variables and balances between opposing tendencies are clearly the kind one ultimately wants to use in any discussion of chemistry. It seems to me that occasionally and unfortunately the organization suffers when ~hysical concepts are used in inappropriate contexts. For example, temperature is discussed a t length in a treatment of molecular motion which deals primarily with vihrat.ion, rotation, and isomerism, while the discussion of claspical kinetic theory of gases begins with a discussion of energy levels. In fairness, it must be said that the energy level discussion is used t o simplify the derivationloss introduction of the Boltzmann distribution by permitting the authors to use sums instead of integrals. On the other hand, most of the authors' applications of the Boltzmann distribution are just as appropriate to continuous distributions. Why not take an extra page or two to di~cus8distributions in general over continuous or discrete sets of levels? The treatment of specific concepts seema to be the greatest weakness of the hook, and this weakness is most apparent in the handling of thermodynamics. I t is characterized principally by lack of sharp, precise statements of definitions, processes, and conditions. Some examples from a rather long list me the treatment of temperature, which is discussed a t length and quite vaguely in Chapters 2 and 7, but is only defined or discussed precisely in two short par* graphs in Chapter 8, and of enthalpy, whichis slipped into Chapter 10 and defined only a t the end of Chapter 12 (and is not in theindex a t all). Anotherexample: the concept of free volume is used extensively t o treat condensed phases and vapor pressure, hut the emphasis seems somewhat misplaced; the authors use the agreement between the model andTrouton'smle toargue for constancy of freevolume rather than for the insensitivity of the result to large differencesin free volumes. They have thereby missed an opportunity t o make some general observations about the sensitivity of calculations from models. The lack of precision is sufficient in the thermodynamics chapter that I would prefer to supplement "Fundamental Chemistry" with a separate short intraductory thermodynanlics text. I t is my impression that the lack of precision is due primarily to the authors' unwillingness

to go entirely to a rigoruua presentation. Had they used their qualitative and intuitive arguments t o supplement more exact statements throughout the book, they would have come much closer t o their ohjective. Despite its shortcomings, this baok is a clear step forward and comes closer than any other single text to an appropriate freshman book for the mid-1960's. I t will certainly be useful, especially to anyone patient and conscientious enough to use its weaknesses for didactic purposes. Unfortunately, it is not the classic which i t might have been; this is the greatest disappointment.

With a few exceptions, the second edition of this unronventional text, which has had its share of admirers and critics, preserves the contents and format as well as the advantages and disadvantages of the original edition of 1055. To those not familiar with the first edition (cf. J. c m ~EDUC., . 32,545 [19551), it should be mentioned thst the book attempts to present to undergraduate students modem structural concepts at tt moderate level as well as the descriptive chemistry usually neglected in the now largely theoretical general chemistry and graduate inorganic COUIBCS.
Many, but not all of the errors in the first edition have been corrected, but unfortunately other errors, especially in some of the figures, have been introduced with the new material. In general, however, the structural diagrams are clearer; the symbols used in the first edition have been replaced hy circles. The number of references a t the end of each chapter, mostly to texts and review articles through 1960 only, has been considerably increased from 174 t o 308. The numher of exercises, still an excellent and unique feature which distinguishes this baok from other inorganic text^, remains virtually unchanged. Those which will be moat challenging t o the more capable students are now designated with asterisks; instructors may now ohtsin answer sheets from the publisher. The introductory chapter preserves the excellent non-mathematical explanation of atomic structure, hut unfortunately also retains the 0 = 16.000 scale of atomic weights without so much as mentioning the C'2 = 12.000 scale. The chapter on nomenclature reveals only minor changes (e.g., 0x0 instead of oxy), but now conforms to the 1957 IUPAC recommends, tions. The section on Taube's "inner" and "outer" orbital complexes has been replaced b y an excellent presentation in which Gould in his inimitable abbreviated manner discusses intelligently in Lss than
four pages ligxnd field effects, the speetrochemical series, douhle-bonding, spinpaired and spin-free complexes, and the Jahn-Teller effect! The derivations for the splitting of tetrahedral and square planar ligand fields a t r e lacking, hut are relegated t o one of the student exercises. Throughout the book, chemical bonding is now interpreted largely in terms of molecular orbital or ligand field theory. I n keeping with current emphasis on kinetics, the major change in the baok is the addition of a new chapter, Some Inorganic Reaction Mechanisms, which present8 topics hitherto completely neglected or inadequately treated. In summary, this revision consists of an additional 43 pages of text, nan-glare rather than glossy paper, a different color cover, and a few additional figures and tables. The following is a list of the added material to be found in the revised edition: Sidgwick-Powell rules (p. 65), boron hydrides (p. 128), Gordy electronegativity scale (p. 146), graphite compounds (p. 154), metal carbon,yls (pp. 157, 336). spinpaired and spin-free complexes; ligand field effects (p. 357), inorganic reaction mechanisms (Chap. 23), ferroeene and sandwich compounds (p. 40'3), square as. tetrahedral complexes (p. 412), electron spin resonance (p. 415), nuclear magnetic resonance (p. GO), and Ziegler catalysts (p. 441).
Far tho instructor of asurvey course, the hook should serve as a convenient "cheek list" of topics t o be covered, hut for student use, it will have to he supplemented with other material, especially in the descriptive sections. GEORGE B. KAUFFMAN F ~ e s n oStat? College Fresno, California

Another appropriate title for this book would be "The Electronegative Nature of Atoms and Molecules." The concept of electronegativity is a central theme in the book and it is exploited with considerable kill. This approach is used very effeetively when discussing amphoterism. The ionic nature of substances is emphasized and considerable effort is expended to keep the student from getting the idea t,hat there are "naked" ions in solution.
