Bands far correlation are broadly classified by the "linkages" involved: C-C and C-H, C-O and S H , C P i and N-H, and those involving other elements. Five pages of correlation charts containing 180 entrips are given first. The remainder of the book contains some 70 more rorrelations. with a detailed dificussion of each. Usuallv included are

such as conjugation, an eleetronegntive substituent, ring strain, etc. Also mentioned are approximate intensity and, in a few classes, the possibility of one's using intensity t o determine the number of given groups in the molecule. For some componnda, where there is disagreement on a correlation in the literature, the author quotes all sides rather fully before stating his position. Some may object to the exclusive use of frequency (cm.?) instead of wavelength, even though a short table of reciprocals is appended; however, the reviewer believes that this shows the author'sforesight. Errors seem to he very infrequent, andmostly typographical; hut the author apparently prefers the cyclic model for diazomethane. The indexing is adequate for the location of a specific individual compound or a class of compounds. However, starting with an unknown substance and its spectrum one would refer to the correlation charts for the possible classes of compounds, and then to these classes in the text. The printing is generally good, hut the type in the correlation charts is too small for reading comfort. The author is to be commended for a good, much needed book. I t will find frequent usein many research and control laboratories. While it is clearly not intended as a textbook, i t might be suitable as a supplement or a source of material in a Course of instruction.

ITIS alway~interesting to look over textbooks used in other countries, for new ideas. This book, designed for general science and premedical students, is not comparable to any book now on the Amerioan market. Ninety psxe;es of general physical chemistry, 130 pages of descriptive inorganic chemistry organized rigidly element by element, and 220 pages of organic chemistry follow one another in a very thoroughly ordered array. The style is more encyclopedic than continuous, and expository than experimental. The flavor throughout is strongly biochemical. Many of the illustrstions are novel, but I doubt that the book as a whole could have much impact toward guiding authors in worthy innovations for the American market. I. A. CAMPBELL

THE INFRA-RED SPECTRA OF COMPLEX MOLECULES
L. I. Bellamy, Prinoipal Scientific Officer, Ministry of Supply, England. John Wiley & Sons, Inc., New York, 1954. xvii 4- 323 pp. 30 figs. 22 tables. 14.5 X 23 cm. $7. PREVIOUSLY there have been only two murces of information on the empirical correlation of infrared spectra with molecular structure: various "correlation charts,'' and the original literature. This volume puts under one cover much of the previously seatteredinformation, and will he welcomed by everyone interested in the measurement and understanding of infrared spectra. Its scope is strictly limited. There are no discussions of experimental technique, though the influence of physical state and solvent is mentioned where important; nor is the theory of molecular vibrations treated, though the results are sometimes used as an aid in assigning observed bands. Other topics, such as hydrogen bonding and rotational isomerism, are treated briefly from the correlation standpoint. The basis for all cearelations is a large number of observed spectra, some unpublished from the author's laboratory, and others from the more than 800 literature references listed; the literature was covered to about 1953. The 30 figures are spectra of some typical compounds. The book is devoted almost exclusively to organic compounds; eiu Dazes describe the soectra of inorganic ions. Of the remainder sbok-80 per cent covers the spectra of organic compounds eontaining no element other than carbon, hydrogen, oxygen, and ni-

There follow nine chapters in which the opportunities open in the fields of chemistry, physics, meteorology, agriculture, conservation, medical research, geology, and a number of other branches of science are disoussed. Included in the descriptions are thumbnail sketches of men and women who have carved out careers in the field under consideration, as well ss fascinating accounts of the scientific discoveries which have made such careers possible. There is a fine chapter on the place of women in the picture, a chapter which, while showing that women are now employed in practically every scientific field, does not minimize the handicaps under which they must work. Mr. Pollack points out the fact that they must usually be satisfied with a lower salary schedule, and that their acceptance is necessarily limited by the emplayer's fear that they will not work permanently. Fittingly, the hook closes with a look ahead, in a chapter en~~
