Books ty of the necessary electrical circuitry for performing the measurements. However, there is a 10-page Appendix written by Richard C. LaForce on the application of operational amplifiers for this purpose. The coverage of the pertinent literature seems to be thorough. There are about 600 references, and most of these are to papers published during the past 10 or 15 years. Professor Fatt not only has a gift for concise, lucid expression, but he also has the ability to critically interpret the significance of experimental data. He was not content merely to describe experimental techniques and catalog the literature, but he also provides interpretations of the significance of the reported results. As far as I know, this is only the second book devoted specifically to the determination of dissolved oxygen. The first was that of Fritz Tôdt (Elektrochemische Sauerstoffmessungen, W. deGruyter & Co., Berlin, 1958) which was concerned with galvanic rather than polarographic sensors. The present book is, I believe, the first to comprehensively describe the applications of electrochemical sensors in medical practice, as well as other biological applications. Anyone concerned with these applications will certainly want to consult this book, but it should also be of interest to investigators in other fields that require measurements of dissolved oxygen. Analytical Chemistry. 2nd Ed. Gary D. Christian, xvi + 648 pages. John Wiley & Sons, Inc., 605 Third Ave., New York, N.Y. 10016. 1977. $16.95
Reviewed by Donald F. Logdson, USAF Occupational and Environmental Health Laboratory, McClellan AFB, Calif. 95652 Although many different courses teach analytical procedures, there are relatively few courses entitled analytical chemistry. However, there is a definite need for a course of this type where the student can learn careful and quantitative laboratory skills and techniques. This textbook is designed for use in such a course. The book includes 25 chapters grouped into 11 parts, three appendices, and a subject index. Part one introduces basic principles and methods of analytical chemistry. Parts two and three discuss data handling and sample preparation. Methods of separation are presented in part four, including chapters on gravimetric analysis, solvent extraction, and chromatographic procedures. Parts five-eight

discuss different methods of measurement, including volumetric methods, electrical methods, optical methods, and methods based on rate. Gas analysis is presented in part nine, and part ten is a brief review of automation in the laboratory. The last part discusses applications of analytical chemistry to such areas as clinical chemistry, drug analysis, and pollution analysis. The first appendix briefly describes pertinent references useful to those studying analytical chemistry. The second appendix is a short review of some basic mathematical operations. The third appendix includes five tables of useful constants. A number of additions and updatings have been made in this second edition. Some experiments have been deleted, and others added to bring the total to 51. It is unfortunate that it was necessary to leave out the chapter on laboratory safety, but this is a minor objection to an otherwise excellent textbook. This textbook should definitely be considered for courses in analytical chemistry and also as a supplementary or reference text for other chemistry courses. Chemisorption: An Experimental Approach. Gerd Wedler (Translated by Derek F. Klemperer). 250 pages. Butterworths Inc., 19 Cummings Park, Woburn, Mass. 01801. 1976. $23.50
Reviewed by W. Henry Weinberg, Division of Chemistry and Chemical Engineering, California Institute of Technology, Pasadena, Calif. 91125 This short book represents an English translation of an extensively revised version of Professor Wedler's text that appeared in 1970 with the title "Adsorption, Eine Einfuhrung in die Physisorption und Chemisorption". The revised text discusses adsorption thermodynamics and kinetics as well as the nature of the adsorbed species from the point of view of experimental measurements. The latter include optical spectroscopies (IR, visible, UV, and ellipsometry), resonance spectroscopies (NMR and ESR), surface electrical and magnetic measurements (contact potential difference, surface conductivity, thermoelectric power, Hall effect and magnetic susceptibility measurements), low-energy electron spectroscopies and diffraction (field emission, Auger, appearance potential and characteristic electron energy loss spectroscopies, electron stimulated desorption, and low-energy electron diffraction), photoelectron spectroscopies (UPS and XPS), and the use of ion beams to
