the National Institutes of Health here became proof of continuing interest in new equipment. About 100 manufac­turers showed their latest items, includ­ing surgical, electronic, optical, radia­tion, and gas sampling instruments. And several thousand visitors stopped, looked, and listened during the four-day show, May 12 to 15.

Sponsors of the symposium were the Washington sections of the American Chemical Society, the Instrument So­ciety of America, the Society of Ameri­can Bacteriologists, the American As­sociation of Clinical Chemists, the So­ciety for Experimental Biology and Medicine, and the professional group on medical electronics of the Institute of Radio Engineers.

The symposium itself consisted of 19 papers divided in six sections: gas chromatography, macromolecules, mi-crorespirometry, aerosols, automatic processing of experimental data, and protein monolayers.

Several items of new equipment that were shown for the first time at the meeting are described in the New Prod­ucts section of this issue of ANALYTICAL CHEMISTRY (see page 55 A).

Industrial Items Horizons Incorporated, through ex­

pansion, is making its vacuum gas analysis facilities available to industry at large for the first time. The com­pany says that, in metals containing from 0.005% to 5% total gases, oxygen and hydrogen content can be deter­mined to an accuracy of ±10% of the total amount of each gas present. In the range below 0.005%, accuracy is ±20%. In special cases samples con­taining more than 5% can be handled.

Schlumberger Well Surveying Corp. has set up a nationwide mar­keting organization for its Model 104 nuclear magnetic (NMR) analyzer. Charles Morgan, sales manager operat­ing out of the company's main offices at Ridgefield, Conn., will be in charge. A. Russell Aikman, company marketing director, says the move was impelled by the great interest in its instrument and the increasing areas of application since its introduction.

Geigy Chemical Corp. has opened a new entomological research and chemical analysis laboratory at Ards-ley, Ν. Υ., for testing Mitin moth­proofed fabrics. The organization in­fests samples of fabrics with webbing clothes moth and carpet beetle larvae for periods of two weeks to determine that they are impervious to damage from the insects. Samples are then tested to determine if sufficient Mitin has actually been applied. Facilities

Results should be expressed in parts per million, and as ions rather than hypothetical combinations. The sum of calcium and magnesium ion concen­tration should be used to calculate hardness. The approved method for hardness would be complexometric or EDTA titration. It was also recom­mended that the ortho-phenanthroline procedures of ASTM and AWWA for

This book is an outgrowth of a short review of flame photometry methods and their applications written in Span­ish for Spanish-speaking analysts. In­terest 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 photom­etry the manual, as the authors prefer to call it, contains a set of practical ideas based on their personal experi­ences. The two men have been asso­ciated 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, analy­sis by flame photometry, instrumental systems, extent and limitations of flame photometry, experimental method, and analytical applications. A short ap­pendix gives recommendations for set­ting up a flame photometry laboratory, and there are several tables on stock solutions, analytical factors, and con­centration conversion factors. A bibli­ography, plus an addendum thereto, lists a total of 909 references. The book closes with a subject index.

This Italian-language volume, the third of "Theoretical and Experimental Contribution to Polarography," is a collection of some works on the activity of the Centro di Polarografia of the Italian Council of Research during the year 1956. The various contributions follow an order corresponding to a gen­eral classification of the polarographic material as adopted by the Centre. That order was maintained in the first two volumes of the series, as well as this one: polarographic methodology; polarographic equipment; theoretical questions; polarographic behavior of some inorganic and organic substances ; and applications of techniques in the fields of chemical statics, chemical kinetics, and analytical chemistry.

There follow some reviews represent­ing the development of polarographic applications to given fields of applied analytical chemistry. The last part consists of about 300 tables of selected

polarographic data. These are in the form approved for documentation on an international scale by the Section on Electrochemical Data of the II 'PAC at its Lisbon meeting in 1956.

1 Volumetric Analysis; Titration Meth­ods: Oxidation-Reduction Re­actions, Vol. III. I. M. Kolthoff, R. Belcher, V. A. Stenger, and G. Matsuyama. ix + 714 pages. Inter-science Publishers, Inc., 250 Fifth Ave., New York 1, Ν. Υ. 1957.

j S15.00.

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 in­volving 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 tech­niques 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 iron-i l l ) , titanium (III) , and other strong reducing agents, and Chapter XV closes the book with a discussion of miscellan­eous titrants. The book contains both author and subject indexes.

X-Ray Crystal Structure. Dan Mc-Lachlan, Jr. vii + 416 pages. Mc­Graw-Hill Book Company, Inc., 330 West 42nd St., New York 36, Ν. Υ. 1957. $15.00.

This book is designed to fill in the

gap which the author feels exists be­tween popular and rigorous treatment of the subject. It discusses determina­tion of atomic positions within a crys­talline material, using x-ray data ob­tained from single crystals. It stresses the theory of space groups, single crys­tal cameras, Fourier methods, comput­ing 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 chap­ter gives examples of six crystalline ma­terials whose structures have already been determined.

The author attempts to give the be­ginner, on the one hand, a foundation of crystallographic concepts. On the other hand, he has tried to give the sea­soned crystallographer a new and novel treatment of a familiar subject. Many diagrams, tables, and charts are in­cluded, 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.

A Short Course in Quantitative Anal­ysis. 2nd ed. Hobart H. Willard, N. Howell Furman, and Egbert K. Bacon, vi + 243 pages. D. Van Nostrand Co., Inc., 120 Alexander St., Princeton, N. J. 1957. $4.25. 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-reduc­tion, and precipitate or complex form­ing—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 physi­cal 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.

Gas Chromatography. A. I . M . Keulemans, edited by C. G. Verver. vii + 217 pages. Reinhold Publish­ing 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 im­portant part in presentation of the subject of this book.

The author points out that use was made in the text of the principal publi­cations 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 fa­miliarity with the fundamentals is essen­tial. 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 chroma­tography and of related physical proc­esses. The second chapter deals with normal practical applications of gas-liquid 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 ap­plied when dealing with difficult situa­tions and nonanalytical applications. Finally, chapter eight is a discussion of gas-solid chromatography.

The book is illustrated with numer­ous charts and diagrams, and has a list of symbols, three appendices, and an author index.
