Also included is s. well-illustrated chapter on "currently" available cammercial instruments. Even though i t is useful to describe some representative spectrometers in dotail-in order to illustrate the functions of components and to permit a discussion of the interactions that various components may have on each other, i.e., a treatment of the spectrometer as a "system" (for example, the tradcoffs between slit width, scanning speed, noise level, costs, etc.)-this reviewer feels that a n attempt in a textbook to provide a guide to current instrumentation simply accelerates its ohsolescence. In view of the fast-growing field of instrumentation, such tasks are better left to the current literature. E. D.

The laboratory exercises are oriented t o a special set of instrumentation (described in Supplement 1) designed by the authors in collaboration with the Heath Company, Benton Harbor, Michigan, and readily available from that manufacturer. It would seem to the reviewer that the many exercises employing this special apparatus could have been segregated t o a supplementary working manual. This is a minor point, however, and does not detract from the general usefulness of the textual material which, in the reviewer's opinion, is a highly recommended compilation and working guide to the many electronic circuits frequently encountered in the laboratory.

dictionaries, a trend in which the first (1953) edition of Fouchier-Billet lays just claim to leadership. Both dictionaries are liberal in entering synonyms under terms, hut are notably less liberal about entering the synonyms in their proper alphabetic places. There arc also notable differences beyond the respective bilingual and trilingual characters. The Ernst dictionary (familiarly so-cdllled because Dr. Ernst has compiled s. series of specialty dictionaries of which this one is not a part) has considerably the larger vocabuIary, about 45,000 terms. I t suffers somewhat more from the infection, so difficult to avoid even among professional translators, of too-literal rendition into English. No lass in clarity has been observed from this minor defect, and a compensating feature is that Ernst exposes himself more to this risk by giving more detail in many of his definitions. Ernst is not quite as meticulous as Fouchier-Billet in chemical nomenclature, especially in that Ernst concedes more than seems needful to old terminology, such as sulfuret for sulfide. Simply as a German-English vocabulary, Ernst is clearly superior; but Ernst's Volume I1 (English-German) must be included for a comparison with FouehierBillet. This leaves to the trilingual dictionary the advantage of a FrenchEnglish and English-French dictionary in the same volume, with the disadvantage A of having a smallw vocabulary. particular merit of Fauehier-Billet is the liberal use of chemical formulae to illustrate names, often with space-eonsuming hut helpful structures indicated. Misprints are uncommon throughout; without any actual comparison, they sewn to occur a bit more frequently in the trilingual dictionary, where the hazards are greater. Captious criticisms aside, both dictionaries are substantial contributions t o interlingual chemical 1exicogra.phy and each serves well its ohiective as set forth in its introduction. Chemists interested only in help with German literature will refer Ernst for its lamer vocahularv:
