This book is an outgrowth of a short review of flame photometry methods and their applications written in Span ish for Spanish-speaking analysts. In terest in that review was great enough so that the authors were impelled to write the present book, translated into English by W. C. Darwell. In addition to basic information on flame photom etry the manual, as the authors prefer to call it, contains a set of practical ideas based on their personal experi ences. The two men have been asso ciated with the Faculty of Sciences of the University of Madrid and with the Institute of Edaphology in Madrid. The book's 25 chapters are divided into six sections, as follows: origin and principles of flame photometry, analy sis by flame photometry, instrumental systems, extent and limitations of flame photometry, experimental method, and analytical applications. A short ap pendix gives recommendations for set ting up a flame photometry laboratory, and there are several tables on stock solutions, analytical factors, and con centration conversion factors. A bibli ography, plus an addendum thereto, lists a total of 909 references. The book closes with a subject index.

It discusses determina tion of atomic positions within a crys talline material, using x-ray data ob tained from single crystals. It stresses the theory of space groups, single crys tal cameras, Fourier methods, comput ing devices, and the phase problem. Such computing devices as Robertson's Strip Methods, the Bragg-Huggins Mask, the Sand Machine, and the Utah Computer are described. A final chap ter gives examples of six crystalline ma terials whose structures have already been determined. The author attempts to give the be ginner, on the one hand, a foundation of crystallographic concepts. On the other hand, he has tried to give the sea soned crystallographer a new and novel treatment of a familiar subject. Many diagrams, tables, and charts are in cluded, and references are given at the end of each chapter. A name index and a subject index are included at the end of the book.

The first two volumes of Volumetric Analysis were published in 1942 and 1947, respectively. Volume I covered theoretical fundamentals of volumetric analysis, and Volume II followed with I a discussion of titration methods in volving acid-base, precipitation, and complex formation reactions. This book on oxidation-reduction titrations becomes the final \rolume of the set. The book contains 15 chapters, the first of which deals somewhat generally with reactions, indicators, and tech niques in oxidation-reduction titrations. This is followed by detailed coverage of potassium permanganate as a volu: metric reagent, and oxidimetry with permanganate and eerie salts. Three chapters are devoted to reagents and their standardization in iodometry, and iodometric determination of inorganic and organic substances. Chapter IX discusses determination of water with Karl Fischer reagent. Chapters X, XI, XII, and XIII cover reactions with potassium iodate, periodate, potassium bromate, and hypohalites. The 14th chapter deals with titrations with ironi l l ) , titanium (III), and other strong reducing agents, and Chapter XV closes the book with a discussion of miscellan eous titrants.

The first five chapters give an intro duction to the topic and to laboratory work, and discuss measurement by weight and volume and evaluation of measurements. The three classes of titrations—acid-base, oxidation-reduc tion, and precipitate or complex form ing—are covered in the following six chapters. Two chapters are devoted to gravimetric analysis, and the final two chapters deal with gravimetric separations and with analysis by physi cal measurements. Several appendices are included, one of them describing the literature of analytical chemistry. A large number of problems are presented at the end of each chapter.

Keulemans, edited by C. G. Verver. vii + 217 pages. Reinhold Publish ing Corp., 430 Park Ave., New York 22, Ν. Υ. 1957. $7.50. The author of this book has access to data obtained not only in Koninklijke/ Shell-Laboratorium, Amsterdam, where he is employed, but also in other Shell companies in the United States and Great Britain. These results, together with the views of specialists on matters of theory and equipment, play an im portant part in presentation of the subject of this book. The author points out that use was made in the text of the principal publi cations on gas chromatography up to Jan. 1, 1956. Literature appearing since then has been referred to only in exceptional cases. In arranging the subject matter, the attempt was made to reconcile practical usefulness with theoretical soundness. In most normal analyses by gas chromatography, the author feels that excellent results can be obtained with little or no knowledge of the underlying theory. But once the investigator leaves the field of routine separations and attacks more difficult applications, he will find that some fa miliarity with the fundamentals is essen tial. For these reasons, the normal practice of gas-liquid chromatography is covered before theoretical matters are discussed. The opening chapter is devoted to a review of the whole field of chroma tography and of related physical proc esses. The second chapter deals with normal practical applications of gasliquid chromatography, and chapter three follows with detailed discussion of equipment required. Chapters four, five, six, and seven cover the theories underlying gas-liquid chromatography, showing how such principles can be ap plied when dealing with difficult situa tions and nonanalytical applications. Finally, chapter eight is a discussion of gas-solid chromatography. The book is illustrated with numer ous charts and diagrams, and has a list of symbols, three appendices, and an author index.
