Unfortunately, Harvard University and the University of Illinois did not collaborate, a f a c t which leaves the d a t a for their regions incomplete and slightly inaccurate. The tables give a most interesting insight into the origin, distribution, and occupation of Ph.D.’s over the most active period of graduate work i n this country. The final chapter, giving its title to the book, offers many sound principles for the improvement of the organization and functions of graduate schools. The suggestions are aimed t o help the weaker and less centrally administered graduate schools and have a strong slant in the direction of the social sciences and education. The concluding admonition t h a t “doctoral programs must be adjusted t o the uses t o which recipients can put the degree i n the scheme of American life today” would perhaps be agreed t o by all if each institution or department is left free t o interpret what is most useful. The prediction that “After w a r shortages in doctoral personnel are made up, i t is likely t h a t for the next score of years society will demand a relatively small number of soundly educated and functionally trained doctors of philosophy” would seem t o have little probability of application t o the field of chemistry, where the supply of doctorates has never fully met the demand.

Price: $3.50. Collaborators who contributed t o this series of lectures under the auspices of Western Reserve University are : Albert S. Keston on “Isotopes and their Applications i n Biochemistry”; Hugh S. Taylor on “Applications of Isotopes in Catalytic Reactions at Surfaces”; H . R . Crane on“Techniques in Kuclear Physics”; Leslie G. S. Brooker on “Resonance and Organic Chemistry”; and W. H . Rodebush, “The Hydrogen Bond and its Significance t o Chemistry .” Under the title “Advances in Nuclear Chemistry” the reader may be surprised or disappointed t o find no reference to atomic power. This was no doubt due t o military censorship, but Dr. Crane’s cha,Jter furnishes a splendid theoretical and historical introdiiction and bacliground for t h a t now much publicized subjcct. S. C . LIND. Frontiers in Chemistry. Vol. 4. Major Instruments of Science and their Applications to Chemistry. Edited by R . E . BURKA N D OLIVERGRUMMITT.151 pp. New York: Interscience Publishers, Inc., 1945. Price: $3.50. This, the fourth i n the series of volumes sponsored by Western Reserve University, i s one of outstanding importance and timeliness. The five well-known contributors cover a field of greatest interest i n modern experimental chemistry: Dr. L . H . Germer on “Electron Diffraction and the Examination of Surfaces”; Dr. L. Marton on “The Electron Microscope and its Applications”; D r . Maurice L . Huggins on “X-ray Diffraction and i t s Applications”; Dr. Wallace R. Brode on “Chemical Spectroscopy” and “Application of Absorption Spectra t o Chemical Problems”; and Dr. R . Bowling Barnes on “The Infrared Spectrometer and its Application.” The volume is replete with excellent figures and photographic illustrations. A subject index adds greatly to the usefulness of the volume. S. C. LIND. Abridged ScientifLc Publications f r o m the Kodak Research Laboratories. Vol. XXVI.
