T h e book is conveniently divided into three main parts entitled "Equilibrium," "Structure," and "Change," and lhese are prefaced with a broadly based introductory chapter. "Equilibrium" deals with thermodqnamics and in this section of the book there have been major revisions. A number of rather obvious omissions have been corrected. T h e concept of thermodynamic temperature is now developed and identified with the perfect gas temperature. "Standard molar enthalpy of formation" is now defined in the chapter on thermochemistry and there is a more detailed description of the calorimetric measurement of AU and AH. Other topics that are treated a little more fully include: the Joule-Thomsan cooling effect and its significance in refrigeration applications, the third law of thermodynamics, and the definition a n d use of the standard Gihbs function. "Structure" deals with quantum mecham ics and its applicatiun to atomic and molecular structure, symmetry, spectroscopy, s t a ~ tistical thermodynamics, and macro mole^ cules. Revision in this part of the book has been less extensive, but some new material has been added. T h e phenomenon of quantum mechanical tunnelling is discussed more fully, and a number of three-dimensional computer graphics are reproduced in the chapters covering quantum mechanics to illustrate the forms ufvarious wave functions. Laser action receives more extensive treatment, the basic principles of most of the different types af laser currently in use being covered.

For the historian of modern chemical theory, Anthony Stranges' new book will surely become as important a resource as Hans Kangrov's "Early History of Planck's Radiation Law" has become for the historian of modern physics since its appearance in English translation in 1976. Additionally, those teachers of chemistry who wish to supplement the normally cursory and abrupt account of the introduction of the shared electron pair concept into chemical theory found in most, textbooks should find Strang e ~ 'portraits of the models of chemical bonding which preconditioned Lewis' semi^ nal proposal of 1916 to he richly suggestive of u s d d heuristic devices. T h e core of the book is bracketed by a first chapter on the nineteenth century origins of t h e electrochemical bond, and by the eighth and final chapter, "The New Theory of Valencey." T h e former reviews the impact of the ideas of Faraday, Davy, and Berzelius. conceptually linked by the work of such fiaures as Laurent, Williamson, Gerhardt, Frankland, and Werner to lhe theory deployed hy Arrhenius at the close of the last century. The last chapter discusses the conflii:t between proponents of the "static" atom-including Lewis, ,I. .I. 'Thornsun, and Langmuir-and those who subscribed lo a "dynamic" view derived from Bohr. Here William A. Noyes is credited with initiating the measures which led to an eventual reconciliation. A brief Epilog summarizes the directions that honding theury was to take after 192:l at the hands of Heisenberg, Dirac, Van Vleck, and Pauling. Rut the heart of the book, h u n d in the middle six chapters, traces the history of theories chemical aSfinity and atomic s t r u c ~

ture from Thomson's discoverv of the electron in 1897 to the celebrated JACS article of Lewis in 1916. In what follows I will attempt t o sketch what seemed to me to be the highlights of Stranges' treatment of this period. With the presentation of the content of the early (1878) papers of Alfred M. Mayer on floating magnets and their impact on Thomsan's eilorts to provide a "visual d e m ~ onstration of the possible arrangement of the electrons in an atom" we see the genesis of Thomson's early vision of the relation brtween atomic structure and chemical periodicity. In retrospect, Mayer's work assumes a n almost ominous aspect in view of the eventual recourse that Lewis and his contemaoraries were to have to magnetic force in descrihine chemical bondine. In anv" case. -~~ ~, Stranges allows us to see the emergence of an atomicmodel that is surely more interesting and suggestive than the raisin pudding Sound in most textbook summaries. Further, we are presented with an overview af the lines of conflict between the rejection of Thomson's model (occurring before Rutherford's ex^ periment) by (principally) Arrhenius, Charles Barkla, and George A. Schott (arising from the model'srailure to arcountadrquately for the number of electrons and the distribution of mass in the atom), and the support which Thomson's views received from the spectro~ scapic studies of Rydberg, Carl Runge, and Heinrich Kayser. Having portrayed Thomson's initial contributions to the electrostatic theory of chemical valence, Stranges allows us to see the extent of the introduction of' such terms as "tubes of force," "residual valence," and "Faraday bundle" into the theoretical liter^ ature of the early twentieth century. T h e last af these terms we find t o hare heen an intrinsic part of the language employed by 01iver Lodge, in 1904, for whom such a "bundle" could form a "full chemical b o n d but which was also capable of making available "a few threads or feelers" for "partial adhesion in cross directions. . . " I n the %?meyear, and with the same electrostatic conceptions, we see Percv Frankland seekine to account far both the*colors of hydrates and solubility differences in terms of the divisibility of the "residual affinities'' contained in the "bundle." Chapters 3 and 4 outline the gradual enlargement of the domain of chemical applications ,,i'Thomson's ideas in the 1891-1909 neriod and the imnaet of this on the thinkine bf American chemists from 1909 l a 1915. 1; a continuation of the story which begins in the first chapter, we are made aware of the persistent efforts which were exerted to make electrostatic attraction the foundation of chemical honding theory The prominent figures here are Richard Ahgg, Harry S. Fry, William A. Noyes, K. George Falk, and John M. Nelsarr. A b e c ~a, n early advocsle of the "rule of eight," emerges as one who was wedded to the idea that "electroaffinity" was capable ol'accuunting Sor chrrnical valence in general, including the "secondary" (nonionic) valences which Werner had introduced into his theory dhondingin 1891 and 1897.
