BOOK REVIEWS ORGANIC SYNTHESIS WITH ISOTOPES, by Arthur Murray and D. Lloyd Williams, Part I, 1146 pages, Price $25.00. Part II, 849 pages. Price $25.00. Interscience Publishers, Inc., New York 1, N.Y. These two volumes are a collec- tion of methods for making"labelled" organic compounds. No biological syntheses are described. In each case of several methods of synthesis, the authors chose a preferred or most feasible one. Part I discusses the synthesis of acids, acid derivatives, amines car- bonic acid derivatives, carbonyl compounds, ethers, heterocyclics, hydrocarbons, hydroxy and onium compounds, sugar, steroid and vita- min derivatives. Part II covers isotopic halogen and hydrogen compounds nitro- gen 15, oxygen 18, phosphorus 32 and sulfur 35 compounds. The syntheses are of interest in ordinary work because they give high yields. A thorough index to both volumes is found in Part II.--M. G. DEN. IoN EXCHANGE RESINS, by Robert Kunin. John Wiley and Sons, Inc., New York 16, N.Y. 467 pages, illustrated and indexed. Price $11.00. The fascinating and expanding field of ion exchange resins has called for this expanded second edi- tion (50 per cent). Much of the old material is rewritten and at least eight categories of new material have been added. In spite of this there is still a void in the cosmetic and toxicological areas. Thurman's work on deodor- ants if mentioned is not easily found. Ikai's work could not be found. The Hofmeister series on page 26 and Gustav Martin (page 292) are not given in the index. Indeed, the index could be substantially expanded. These minor discrepancies do not detract materially from the text which is a useful companion to the limited number of books on this subject. The illustrations are first class. In fact the whole presentation is excellent. No errors were noticed in going through the text.--M. G. DEN. INDUSTRIAL FATTY ACIDS AND THEIR APPLIe^TION, by E. Scott Pattison. Reinhold Publishing Corp., New York 22, N.Y. 230 pages, illus- trated and indexed. Price $7.00. The coverage of this book in- cludes processing and production of fatty acids with emphasis on prac- tical technology. The author is in an excellent position to bring together practical data which might not otherwise be available. Hence both author and his sources are to be congratulated. Sixteen chapters are contributed by twenty collaborators in addi- 190
