This book is a little narrower tlran that I t does not include such very simplr derivatives sa hydrogen, sulfur, carbon lhlack, emban dioxide, and carbon disc& fide (but does cover ammonia). In the rlireetion of complexity, it ignores mixtures lhet are markptpd as mrh-slkanc i~.xrtions used as solvents, naphthenir. nrids, the products of chlorinnting nnd sulfonnting the higher alkanes, ;and o l course fuels and lid,~.iemts.

The reviewer missed disrussions of wee, m~thanethiol. 2-l~ydmxy methyl-2-methyl-l,3-pr,rapanediol (tximethylalethane), and slkylnted phcnols. Some miaspelled names of products and Iproaesses (Arosorh, Acrilan, Emulphor, Girbotol) and of authors escaped the prodrcader's cye.

JOURNAL OF CHEMICAL EDUCATION

Isomerism; Walden Inversion; Geometrical Isomelkn; Stereochemistry of Diphen>-l Compounds; Steriachemistry of Elements Other than Carbon. The chapters treating the chemistry of natural product^ are: Carbohydrates; Terpenes; Cwotenoids; Polyeyclic Aromatic Compounds; Steroids; Heterocyclic Compounds Containing Two or More HeteroAtoms; Amino Acids and Proteins; Alkaloids; Anthocyanins; Purinesand Nucleie Acids; Vitamins; Chemotherapy; Haemoslobin, Chlorophyl and Phthalocyanines. Each chapter is concise, thoroughly up-to-date and concludes with a brief hut. stimulating list of references. An index of authors and an index of subjects, with name reactions ineloded in the latter, are provided. The wealth of material compacted in this volume would be suitable for an xdvanced undergraduate semaster cotme in organic chemistry or, with suplllementary reference materials, for a semester graduate course. Only a few highlights of the topics can be cited. Dipole moments, solubility and X-ray analysis, the refrachor, and neutron diffmction patterns are dealt with. The uee of three-dimensional models for optical isomers, and their planar repnsentntions, are given pl.ecisely. The terms (+) and (-), dextro and levo, D 2nd L w e all employed with clarity. Especially noteworthy is the hest evidence for configrwations of a- and @anomera, and the proofs of structures znd

configurations of carbohydrates, not only from traditional information but also by modern X-ray and oxidative methods. I n developing material in the second section, the author takes pains to select important proofs of strwtnre, synthesis, and mechanisms of reactions. There are errors and omissions, but these me relatively unimportant. In describing the Vagner-Meerwein rearrangement, an Ilnfort:lnate error refers to an intermdiate iwhanion rather than a curhonium ion. The "roneelted action" idea would be useful iu connection with the h~~omonitm ion intennrdiate and with the mechanism for the Beckmnnn rean'sngemwt. Too frequently the author infers or states t,hat a compound is found in several sources, without giving even one source. I t is iut,eresting to find the structure for the antihiotie, m,ycamycin, ne the only known natural allene, with optical activity. The mechanism of stsreospeeifieity in dehydration of ally1 alcohols to d l e n e ~might he supgested. Some errors in nomenrlature occur. A reference to Selaood's hook on "Magnetochemistry" should be cited in connection with the topic of magnetic suseeptibilities. Certainly ~ r f ~ r e n cshould r be made to Jack Hinds "Physical Organic Chemistry." Kevertheless, the zothor hap guided a scnsible course through the prolific array of infolmntion with remwkable continuity. .JOHN LEO ABERNETHY Fn-sw STATECO~,LEOE F n ~ s s oC , ~~zronnm
