ANALYTICAL CHEMISTRY
than by graduate chemists. This ac counts for the fact that the description of analytical procedures given in this book is found to contain much detail, partly repetitive, which would seem to be stressing the obvious, but is really in tended not to leave any room for doubt as to the correct procedure to be fol lowed. The techniques of trace analysis covered in this book reveal the state of the art in the USSR as of 1965. A ma jority of the procedures involve chem ical preconcentration and separation followed by eolorimetric or spectrophotometric determination of individual trace elements. Also quite prominent are chemical preconcentration-emission spectrographic methods for survey anal yses. To a lesser extent activation anal ysis, polarographic, and luminescent methods are employed, all accompanied by the necessary enrichment and/or separation steps to achieve adequate sensitivity or freedom from interfer ences. I t is interesting to note that al though continuous reference in the book is made to the great potential of spark source mass spectrometry for the analy sis of high-purity materials, only very limited use is made of this valuable technique, presumably due to the non availability of instruments. Also, no ticeably absent are flame emission and atomic absorption methods. This book is a welcome addition to the growing list of authoritative texts on trace anatysis. Although it is re stricted to the analysis of semiconductor materials, it provides considerable de tail of great \ r alue to the practic ing analyst concerned with this demand ing field. The book is written in a clear and straightforward manner and the Israel Program for Scientific Translations is to be congratulated for the high quality of the translation. The only annoyances encountered by the reviewer wrere the absence of a subject index and the fre quent use of the word "étalon" for "standard" in this English edition.
New Books Proceedings of the International Conference on Luminescence, Budapest, 1 9 6 6 . Vol. 1. Vol. 2. O.
Szigeta, Editor. 2165 pages. Akadémaiai Kiado, Budapest V'., Alkotmany U. 21., Hungary. 1988. $72 These two volumes contain in English the papers presented at the International Conference on Luminescence which was held in Budapest in 1966. The three introduction lectures by Prof. Garlick, Prof. Levshin, and Prof. Seitz are in both English and Russian. The
subject matter of the conference encompassed general problems of luminescence, the problems of organic and inorganic luminescent materials, especially of oxides and sulfides and rare earth metal compounds, the phenomena of injection luminescence, solid state lasers, and the application of luminescence. Inorganic Qualitative Analysis: A Short Course for Introductory Chemistry. 2nd Edition. Richard B. Hahn, Frank J. Welcher. viii + 326 pages. D. Van Nostrand Co., Inc., 120 Alexander St., Princeton, N.J. 08-540. 1968. $6.40 This book was written as a text for Freshman chemistry where qualitative analysis is offered in the laboratory portion of the latter p a r t of general chemistry. Changes made over the first edition include a complete reorganization of the theoretical sections, and substantial revisions in the chapters on chemical equilibrium, chemical kinetics, and ionics.

Paperbound. $3.35 This text has been designed for use in schools where a separate course on qualitative analysis has been abandoned and a simplified scheme of analysis is used wdthin the laboratory exercises of general chemistry. The analytical procedures within the cation scheme are based on the Fresenius system of analysis, but they have been greatly altered in terms of efficiency and simplicity. The anion-anah^sis echeme is adapted from one developed by J. T. Dobbins and H. A. Ljung [J. Chem. Educ. 12, 586 (1935)]. Analysis and Characterization of Oils, Fats and Fat Products. V o l .

Volume 2 contains seven articles on various aspects of fat analysis and author and subject in dexes. Titles of the articles and their authors follow: Mass Spectrometry in Fat Analysis by Einar Stenhagen; Measurement of Oil Colour by Maurice Naudet and Elie Sambuc; Paper and Thin-layer Chromatography in F a t Chemistry by Peter Vogel and Theophil Wieske; Analysis of Glyoerides
