Although the hook represents an effort to fulfill these needs, there have been many books written in the field of thermodynamics which encompitas the above three features. The chemical engineering and chemistry professors will find little in this book, for their purpose, which has not been covered in other mechanical engineering thermodynamics texts. The classical approach is used in the treatment of the second law. Chapter ~

six deals with the Kelvin-Planck and the Clausius statements, the Carnot Cycle, and the thermodynamic scale of temperature. In Chapter seven the inequality of Clitusius is introduced and the entropy is defined. Availability and irreversibility are covered in Chapter ten. As is usual in a mechanical engineering thermodynamics book, there me separate chapters an refrigeration, compression of gases, vapor power, cycles, and fluid flow topics. Chapter 15 contains only 45 pages on the subiect of chemical resetions and -~ combustions. Most of this discussion is relatively elementary for the chemist and chemical engineer. In Chapter 16, only 21 pages are devoted to the chapter on equilibrium. Although the author writes with clssity ~

With the growth of the use of ferrw magnetics in the communications and other technological fields, a vast amount of theoretical and practical information has been obtained concerning these compounds. This volume of the Gmelin Handbook attempts, with some success, to bring up-to-date the literature dealing with the magnetic and electric properties of various alloy systems. In some instances, literature as late 6s 1957 is included. One small section of this volume deals with the terminology and symbols of this field, and a second section with the theoretical aspects of ferro-magnetism. A comprehensive description of ferro-magnetic materials that should prove useful both in fundamental and applied research is given. Alloys of iron, cobalt, nickel, manganese, and chromium are treated herein. A large section is devoted to ferro-magnetic semi-conductors. Special mention must be made of the se:tion devoted t o patent literature concerning the preparation and the heaetreatment of magnetic materials, which should be valuable in the field of applied research. There is a special alphabetical cataloguing of the alloys and oxide systems in this section. The subject index is given both in German and English.

Volume 6 is chock-full of good material. It is divided into five main sections. The section on Liquid-Gas Systems contains three fairly thorough chapters on Gas Absorption Column (73 pages), Operating Characteristics of Packed Ahsorotion Columns (17 pages), and ~ v a ~ o r a t i o n Practice (50 pages). The section on Fluidization contains two excellent chapters an Fluidisation and Fluidized Beds (28 pages), and Applicapages). tions of Fluidization (50 . . . (Continued on page A44)

BOOK REVIEWS The section entitled Multicomponent Gas Svst,ems contains chapters on Liquefaction and Fractionation of Gases (54 pages), Adsorption (45 pages), and Refvigeration Practice (52 pages). The section on Liqnid-Solid Systems is the most romplete of this particular volume. This seetion contains chapters on Lcsching (20 pages), Crystallization ( 4 4 pngcs), Colloids (41 pager), Filtration (11 pages), Select,ion, Sizing, and Operat,ion of Filters (41 pages), and Centrihiging (39 p"ges). The final section contains the chapter Sublimation and Vacuum Freeze Drying (33 pages). Vohtme G carries on the t,hurnoghncss 3f t h previous ~ five vohlmes.

we understand by chemistry both the pure and applied subject. The contributors are far the most part English, but there are as well two articles from France, two from Russia, one from Wales, and one from Australia, giving the collection an interJ o a J. ~ M c K E ~ national flavor. The purpose of the Uniuersity of Tezas volume is to honor Professor N. K. Adam Austin as he retires far his achievements in the physics and chemistry of surfaces. It was in 1917 that Lmgmuir's classical Surface Phenomena in Chemistry and work on surfaces appeared in print, so the Biology subject to whioh thc "guest of honor" hits Edited by J . F. Danielli, K .

I t s title is films and soaps; this i t is, but a t the same accurately descriptive of these reports if time in i t the philosopher speaks. The old order is changing and students of chemistry who read Tms JOURNAL will be here made again aware of this situation. Mare than half of the reports deal with subjects in the physical chemistry of surfaces. Many of them are very good critical review articles which perform the function of sorting out positions which could be consolidated from those of weaker foundation. Relatively few fall into the oategory of original research reports, no doubt by intent of the editors. Several of the reports which have t o do with applications t o biology were of special interest t o this reviewer. One of them by Hartley and Brunskill is a study of the physical mechanism of the reflection of water drops from surfaces, a subject of importance in connection with tho application of ineectieides. Another is a oomprehensive review of eel1 membrane physics and chemistry by Ihnielli. Still another by Davson describes tho use of the Gibbs-Donnan equilibrium to study relationships between biological fluids. The editors and authors have done a very nice thing for their eminent scientist friend, Professor Adam. The publishers have produced a n attractive volume and have kept the prioe a t a. reasonable figure for this type of publication. It hss been a successful enterprise and all involved are to he congrstulnted upon their success in providing the ohemied world with a collection of interest and value.
