BOOK REVIEWS 1905, of the Geophysical Laboratory of the Carnegie Institution, where experimental physic$-chemical studies of rockforming oxide and silicate systems were initiated in earnest. Since this time, and especially during the postwar period, experimental geochemistry ha. flourished and been extended to more complex silicate and oxide systems, under hydrothermal conditions and a t increasing higher P-T conditions. In addition radiochemistry has sided the Earth Scientist immensely through its applications to geochronology and study of natural isotope distribut,ion. We should mention alao the more recent development of physical organic geochemistry. The title of Professor Smith's n e v book is, therefore, somewhat misleading in that he does not attempt to cover all aspects of what might really be called Physical Geochemistry. The hook is devoted entirely t o those aspects of experimental physiral-chemistry which relate t o the melting and crystallieation of rocks and the deposition of minerals, in the tradition of the Geophysical Laboratory. Part I of the book (156 pages) deals with a cwsory review of some of the physical and chemical properties of phases, systems, and processes. There is a short chapter dealing with each of the topics: structure of matter, solution in rrystals, defects in crystals, crystalline polymorphism, liquids, gases and gaseous solutions, heterogeneous equilibria and the phase rule, and phase diagrams. None of these topics is dealt with in sufficient depth to permit the uninitiated student to fully comprehend the significance of the latter p w t of the hook. Part I1 of the hook offers quite rewarding reading and deals with the physical chemistry of real syst,ems and it^ application to rock and mineral genesis. Part I1 consists of nine chapters devoted t o rather detailed discussion of the topics: silicate systems and igneous processes, silicatemetallic oxide and sulfide systems and magmatic processes, water-silicate WEtems, metallic sulfide-water systems and hydrothermal processes, silicate-sulfidewater systems and magmatic processes, igneous and metamorphic rocks, pegmatitic and contact metasomatic deposits, hydrothermal mineral deposits, and geothermometry and geoharnmetry. Professor Smith's greatest contribution here is in synt,hesiaing, largely in graphical form, a tremendous amount of data, formerly dispersed through a varied literature. The extent of his coverage is evident in a 47-page bibliography which constitutes one of the most, valuable contributions of the book. One must admire Professor Smith's courage in extrapolating data and principles into regions for which good experimental data is lacking. I n spite of the wealth of data ~ r e s w t e d ,one cannot but be impressed with the amount of basic data still lacking t o geochemistry. Very little is k n o m yet, for example, about such basic things as the solubility of simple compounds a t moderate to high temperatures and pressures.

Though intended primarily for geologists snd mineralogists one would hope that more chemists, stimulated by Professor Smith's fine treatment, might find some of the problems dealt with here truly challenging and turn their research attention toward physical geochemistry.

Robert Perry carries on in the footsteps of his famous father, John H. Perry, editor of the first three editiana, with the help of Cecil Chilton, Sidney Kirkpatrick, and a staff of 110 experts t o completely revise the third edition of the "Chemical Engineers' Hmdboak." This handbook has been fully moderniaed. Over 1300 updated pages will tell the reader about the latest developmente and most advanced procedures. Among the many changes is a regrouping of unit operations on the basis of clme inter-relationships of chemical principles and operating practice. This emphasis on fundamentals makes the book even more applicable to specific problems in such developing fields xs missiles and nucleonics where a "ha,rdware"-oriented spproaeh would immediately be obsolete. Among the many changes and improvements are: More coverage on pressure vessels, piping, power drives, lubrication, speed reducers, and other important information to help you select, apply, and maintain your process equipment. The unified approach to adsorption and ion exchange which treat these subjects from the kinetic approach as well as from the thermodynamic viewpoint. New presentation on heat generation, transport, storage, heat transfer equipment, reaction kinetics, and reactor design. The experts provide up-to-date material on the dynamics of falling 6lms in fluidized beds, electromagnetic pumps, jet pulverizers, grinding theory, unsteady-state diffusion, the use of computers in designing multicomponent distillation processes, and many othen. The handbook has 26 i d l y revised sections compared to 30 sections in the third edition. There are approximately 2000 illustratiom in this new book. Fortunately, the publishers h w e continued the large page size (7'14 X 9'18) which makes the handbook easy t o read. The index is even better than the third edition. Even though you have a third edition, this new edition should he on your book shelf University of T e r n Austin
