Interscience Publishers, Inc., New York, 1957. ix 714 pp. 15 x 23 cm. Price $15. The third and last volume of “Volumetric Analysis’’ deals exclusively with oxidation-reduction titrations. It is logically arranged in a series of fifteen chapters, is well documented throughout, and is provided with author and subject indexes. The first chapter discusses reactiohs, indicators, and general techniques in oxidation-reduction titrations. Other chapters discuss potassium permanganate as a volumetric reagent, oxidimetry with permanganate and with ceric salts, potassium dichromate as oxidizTables for Use with Binomial Samples.

Science looks at Smoking: A New Inquiry into the Effects of Smoking on Your Health. By ERIC NORTHRUP.Coward-McCann, Inc., New York, 1957. 190 pp. 13.5 x 20.5 cm. Price $3. An effort is made t o inquire into the effects of smoking, and to appraise some of the reports that have been so widely circulated. The reports on smoking as a cause of lung cancer and heart failure are reviewed and evaluated. The author points out that faulty research methods and preconceived attitudes have made some of the publicized conclusions invalid and suspect, and that as a result the public has been unduly alarmed by the hasty release of inconclusive reports and findings.
