Most of the reviews appear to have been written in 1976, and some citations are to work published as recently as early 1976. The reviews generally deal with a very specific research problem and emphasize the results and developments from the author's laboratory. Thus, the series is not comprehensive and does nut uniformly cover the field of hioorganic chemistry. Instead, the reviews present the highlights of some of the more exciting work that has been accomplished in

written for the graduate student or professional, several of the reviews would be excellent reading for the undergraduate. One example is the second article in m h n e 111 which reviews research in the possihle chemical events leadine" to the formation of a primordial cell.

Using Digital and Analog Integrated Circuits

Shacklette and Ashworth, in their hook, "Using Digital and Analog Integrated Circuits" have provided a very practical primer for any laboratory course which introduces the use of analog or digital "chips." The word "Using" in the title is the key to what their book about. The authors devote 123 pages to digital circuits covering gates, co ole an algebra, buffers, flip-flops, decoders, counters, adders, registers, and memories. In most of the digital topics there are two coverages; one using a T T L and the other a CMOS device. In 88 pages the section covers the operational amplifier, the non-inverting amplifier, integration and differentiation, comparators, Schmitt trigger, the logarithmic amplifier, constant voltage, and current sources, power amolifiers. active filters. and relavs. In hoth

lems. Fifty-six pages are devoted to 12 projects which involve the construction of some practical device ranging from an electronic music box to a multiplexer. Projects are meant t o apply what has been developed already. The 41 pages of appendices cover sources of equipment, data sheets, a glossary and utilitarian circuits for power supplies, and a logic probe. There is a four page index. The authors provide a list of very practical references. Among them are several trade manuals. In the only noteworthy oversight that I could detect Hoenig and Payne's useful hook ("Haw T o Build and Use Electronic Devices Without Frustration, Panic, Mountains of Money or an Engineering Degree, Little") is mentioned in the preface but rrmitted from the reference list, and nowhere does the title and publisher appear. I believe there are three aspects to practical laboratory work with which such a book must deal. First, the experiments, if they are to be done by each student individually or in pairs, must use inexpensive components and the authors must tell how to procure them. The authors do a superlative joh in that. They have addresses of 14 suppliers of cvmponents including the main surplus suppliers. Fur-

thermore, they give frank suggestions about the best sources of components. They are clearly experienced a t procuring cheap parts. Departments with even the most meager budget can include instrumentation with state-of-the-art components with the help of this book. Second, the authors of a laboratary book cannot afford the luxury of going into great theoretical detail. They must have the rare ability to deal concisely and clearly with components in paragraphs or sentences where "theoretical" books use chapters. Othenvise the laboratory work becomes much more time consuming than can he afforded generally. The authors have some excellent exposition. They demonstrate that one can intelligently use an LED or an ap amp without knowing solid state theory or Kirchoffs Laws. Third, the exercises should have some applicability to other subjects. That is, the electronics should not be an end in itself. The chemist could be disappointed in this book since none of the experimentsor projects has a specific chemical application identified. To use it, an instructor will need to exercise some imagination. For example, although analog differentiators, null detectors, and relay controllers are dealt with separately in an understandable way, an automatic titrator is not covered. The authors intend for the text to accompany the second semester of an electronicsfor-scientists course covering discrete components. However, it does not draw heavily from that and could accompany a first semester course if students were already familiar with common test equipment, resistors, capacitors, and perhaps Ohm's Law. I believe the hook is well suited to accompany a junior level lab course in physical or analytical chemistry; however, it will require supplemental resources to deal with specific chemical applications.

"Optoaeaustie Spectroscopy and Detection" is a text of eight chapters written by nine authors and edited by Joh-Han Pao. Although the general quality of the text makes it a welcome addition to the field, it does fall prey to several weaknesses common to multi-author texts.
