rhanges h a w bccn mado. A s c p a c ~ t e chapter has heen devoted to t h r rclat,ionship of optical properties to crystal stmrtun! with expansion of thc subject matter and inclurian of l&oratory experiments. The chapter on rofraetivo indm dekrmin;~tinnhas heen moved to follow the chapter on the study of materials hy means of the polarizing mieroscopc ~ h i c h is a more logical fiequencc of presentation than appeared in previous editions. The chapter on the polarizing mirroseope has hecn expanded to include a discussion and illr~strationsof the ellipsoids of revolution for the wave fronts and refrartivt: indices of uniaxial and hiaxial materials which art: essont,ial for an rmdorstanding of the interference phenomena ohscrved with conascopic polarized light. Also includsd is a colored reproduet,ion of thc 3lirht:l-Levy chart for birefringence. The chapter on ultramirn,scopy has heen revised and enlarged to conform to the modern underatanding of colloidal phenomena with cmphnsis on the continuit," of colloid chemistry with surface chemistry. Lnhoratory cxperimcnts are included to emphasize this point. Extensive reference is madc throughout the text to the application of the olcctron microscope to the solution of chemical problems. The separate new chapter on the electron mieroaeopc, while i t will give the student an appreciation for this field, lmfortwmtely ovcrcmphasises hoth the diffieultirs encounterd in the use of the elcrtron microneope as well as the diffiedtiw in the interpretation of the results, which may discourage the student from a morc seriou. look a t this important tool. The author has excellently integrated all of the recent developmcnta in hoth instrumentation and methodology into this well-estrtblishcd "Handbook of Chemical i\licroscop,y." Tho hook is well indexed and ref~mnredfor hackground rcrtding and, as a result of the ostensive revisions made, will he cven more eonsidered the Bihle of tho s t d e n t of chemical microscopy than its predecessors.

Only four years have elapsed since the first edition of this hook. The present edition is about 100 pages longer than the first; this is due in part to a new chapter on the origin of group frequency shifts, rtnd part t o more information put in the older chapters. Out of some 250 sections disousaing specific group frequency and intensity shifts, twenty are new. The brief oorrelation tables have, in spite of this, been sesroely affected. The 30 figures are identical with the first edition. In bringing the literature up t o date, the author states he has added over 700 new references. A breakdown of this increase shows the greatest activity in earhonyl correlations, followed by the chapter an amidos, proteins, and polypeptiden. Discussion of other nitrogen compounds has been significantly eapanded. Many people will find the new chapter the most valuahle addition, though it, will surely generate debate; others will find the recent literature addition most heloful. While the first edition is not ohh&e, most of those who purchased i t will need to have the second.

The preface to preceding volumes states the purpose of hhis annual ppuhlication: "New methods for the sgntheais of organic compounds, improvements of known methods, and also old proved methods scattered in periodicals, arc being recorded continuously in this book series." The usage of reaction symbols is defended on the hasin of systematic ela~sificationwithout reference to trivial and author names. Volume 12 lists 965 abstracts of organic syntheses which appeared between 1955 and 1957. A aurvey of the total ref-
