However the basic principles of AA, AE, and AF are covered and the similarities between the techniques are stressed as they should he. In conclusion, this hook is suitable for a undergraduate course in speetrochemieal analysis. It appears best suited for a spectroscopy course taught by both an analytical and structural chemist because of emphasis on both quantitative analysis and structural information. James D.Ingle.

Chromatographic Analysis of the Environment Edited by Rohert I,. Croh, VillanovaUniversity. Marcel Dekker, Inc., New York, 1975. x + 734 pp. Figs. and tables. 23.5 X 16 rm. $49.50. This monograph has been compiled "to
value to consultants, engineers, chemists, and students." The 19 contributors have presented an abundance of information, although its value will be limited by an apparent two- t o four-year interval between the writing ofseveralchaptersand their assembly into this volume. In order Lo minimize repetition in later chapters, theory and the general features of the practice of chromatography are described in a plenary section. Subsequent sections deal with air pollution, soil chemistry, water pollution, and waste chemistry. Within each section are chapters describing applications of gas, liquid, paper, and thin-layer ehromatographie analysis. lon-exchange analysis chapters are included in the sections on soil rhemistry and water pollution. A brief table of contents precedes each chapter. Although this hook contains four chapters on each of the main typesof chromatography, the introductorv oases .. of each chaoter demonstrate significant variety. Within the chapters, however, three different styles of presentation appear: (1) intimate experimental detail, (2) a repetitive listing of who (by name) did what, and (3) a prablem-oriented discussion (with minimal name dropping) sufficient to guide the reader toa useful analytical method. T h e inclusion of experimental detail in the paper chromatography chapters appears to this reviewer t o be inconsistent with the declining use of this mature technique. T h a t space might have been better used for a discussion of sampling techniques, an aspect of analysis covered minimallv in this volume. The paucity of references more recent than 1970 or 1971 in several chapters deprives the reader of the latest advances in chromatographic methods. Although this monograph will pnwide the analyst with a comprehensive foundation for his search for a method t o fit the p n h l e m a t hand, his studies will need t o he supplemented with publications like Analytical Chemistry's Annual Reviews.

tailed laboratory experiments. Module I is designed for students with little or no background in electronics. I t includes sections on data domains, interdomain conversions, current measurements, voltage sources and measurements, and servo measurement systems. Module I1 covers basic properties of passive elements, switching devices, basic amplification circuits, and feedback control concepts Module I11 reviews data domains, the nature of analog signals, time domain measurements, and interconversions. I t then introduces digital teehnioues and analoe-dieital conversions.

module is of great value t o an advanced student. I recommend that all graduate students in analytical or experimental physical chemistryobtain a mpy, read it carefully, and then keep it on hand for ready reference. One of the important features of this book is its comprehensive nature. Most of the topics can be found in other places, but the reviewer knows of no other book t h a t brings it all together in one place. However, as aresult, the depth of treatment is not adequate for some users and other sources might need to be consulted. For example, section 2-2.3 includes a discussion of operational-amplifier differentiators. The basic concept of the circuit is presented clearly as are the problems associated with the differentiation of a noisy signal. However, no mention is made of the stability problems of the simple circuit, the degree of loading of the signal source, or the necessitv of an auxiliarv feedback to k e e the ~ not be regarded as a source of instructions by which practical instruments can be designed and constructed, but rather as a n introduction to numerous important concepts. As such it is highly recommended. Peter Sturrock
