RECENT B M K S CATALYSIS,INORGANIC AND ORGANIC.Sophia Bnkman, J w p e C. Muwell, and Gustav Egloff, Universal Oil Products Company, Research Laboratories. Reinhold Publishing Corporation. New York City, 1940. xi 1130 pp. 75 figs. 15 X 23 cm. $18.00. I n the one volume CATALYSISthe authors have gathered together a relatively enormous amount of factual material, drawn from the whole field of catalysis and covering the period from the present back over many years. Because of the considerable divergence of opinion with respect to the mechanism of catalysis and to the interpretation of experimental data the authors have preferred "to arrange the findiogs of the various workers in the field and their original interpretations into a systematic presentation of the subject with some consideration of its historical evolution!' Thus the presentation is encyclopedic rather than critical. The hook is divided into eleven main chapters with appended bibliographies, and is well indexed as t o subjects and authors. The chapters are devoted to the following subjects: The Phenomenon of Catalysis; Adsorption and Catalysis; Heterogeneous and Homogeneous Catalysis; The Activity of the Catalyst; Inhibitors in Catalysis; Promoters and Poisons in Catalysis; Carriers in Heterogeneous Catalysis; Catalytic Reactions in Inorganic and Organic Chemistry; Physical Conditions in Catalytic Reactions; Classification of Catalysts with Respect to Type of Reaction; Catalysis in the Petroleum Industry. Very extensive use is made of tables in a systematic presentation of facts, so that even though the book is large, its data are readily available. "It is the belief of the authors that future research in the field of catalysis may be Logically derived from the systematically presented facts instead of from the empirical methods used a t present." The authors have made an important contribution t o the literature of catalysis and have created a source book to which all those interested in the catalytic field will wish to have access. W. W.

tative analysis, the second edition includes this procedure presented as schemes for use either with centrifugation or with small filters and funnels. Important changes in the procedure involve the separation of the cadmium and cupric ions by the use of cadmium chloride complex ions t o decrease the cadmium ion concentration sufficiently to present the formation of cadmium sulfide; the use of hydrogen peroxide t o oxidize stannous ion to stannic ion; the use of the bisulfate ion as a weak acid for use as a buffer solution in the Group I11 analysis; and a separation of strontium and calcium based on the acidic nature of the bisulfateion. The section an anion analysis has been improved and expanded. I t is designed t o encourage the student t o use his ingenuity and his knowledge of both anions and cations. Throughout the text a very adequate number of chemical equations, tables of data, and other pertinent information for the solution of problems are given. The appendixes include, in addition t o the expanded tables about reagents, a section on mathematical operations and tables of ionization and dissociation constants, This second edition should prove to be more popular than the first.

Ionrrc EQUUIBRIUMAS APPLIEDTO QUALITATIVE ANALYSIS. T. R. Hogness and Warren C. Joknson, University of Chicago. Henry Holt and Company, New York City, 1941. vii 306 pp. 23 figs. 14 X 23 c m . 52.W. This text consists of the theoretical part (Part I , or the first 271 pages) and the appendix of the revised edition of QUALITATIVE ANALYSIS AND CHEMICAL EQUILIBRIUM.(See preceding review.) As exmessed bv the authors. "it is desimed t o meet the needs of teachers who either prefer to use thcir own particular scheme of analytical procedure or want to include in their courses supplementary rnaterial on chemical equilibrium in the form of problems and exercises." This text should find wide application by teachers of qualitative analysis; the authors are t o be commended for making available this material in the form of a separate text. LAURENCE L. OUILL ~~~

QUALITATIVE ANALYSISAND CHEMICAL EQUILIBRIUM.T. R. Hogness and Warren C. Johnson, University of Chicago. Revised Edition. Henry Holt and Company, New York City, 1940. xvi f 5 3 8 ~ ~33figs. . 14 X 23cm. $2.90. The revised and expanded edition of this textbook is exactly what would have been expected as a development from the wellplanned and well-written first edition [reviewed in J. Cnemr. RDTP..14. 448 (1937) . ..1. AS in the earlier edition the methods of presentation are matter-of-factand the literary style is simplr. Any trachrr of qualitative analysis will find this text to be stitnulating and to contain very north-while swz~stionafor PrCSenting chemical equilibrium t o students of qualitative analysis. he new hook is larger (by approximately 120 pages) and the revision is extensive. Many sections were entirely rewritten and extensive insertions were made in all but a few of the chapten. Chapter 1 includes a more extensive discussion of the nature of ionic structure. Chemical equilibrium is the main theme for Chapters 2 t o 9. The Br$nsted concept isemphasized in Chapters 2, 6, and 8. The compilation of questionsandprohlems which illustrate the various principles outlined in each chapter serves to summarize and emphasize the principles discussed. A study of these problems should definitely clarify the relationships existing between the theory of qualitative analysis and the laboratory phase of the course. This interesting and very useful part of the text includes the first 271 pages. (This part of the hook is reprinted as a separate text. See next review.) The more significant changes appear in the Experimental Part, or Part I1 of the text. Whereas the first edition utilized essentially a small-scale adaption of the Fresenius scheme of quali-

New York City, 1941. 43 PP. 13.5 X 19.5 cm. $0 60. As a brief introduction to the subject of bibliography in an attempt to cover the needs of first-year library school students, this is a general work and as such would be of help to a bibliographer of chemistry, hut does not meet his problems specifically. The pamphlet is divided into four chapters discussing: definitions, types, functions, and objectives of bibliography; hibliagraphical form; evaluation of bibliographies; compilation of a bibliography.
