M. Ren• Colson ANNUAL GENERAL MEETING OF THE SOCI]•T]• FRAN•AISE de COSM•TOLOGIE Annual General Election Held at the Maison de la Chimie T•otro• •ov associated with the SOCIETY or COSME•'XC C•XEMIS•'S, the aims of this new French group and that of the SOCIEX¾ of Cos- WE•IC C•EWIS•S are much the same. The relationship between the French group and the British Society of Cosmetic Chemists is more close by gei•graphy as well as with the per- sonalities involved. To this extent, the new President of the Soci&• Francaise de Cosm•tologie, M. Ren• Colson, sent this message to the Society of Cosmetic Chemists of Great Britain on the occasion of the election of the new officers listed be- low. "I sincerely hope that our two related societies of Cosmetic Chem- ists will develop their fraternal and technical contacts on all possible occasions in the future." It is therefore most pleasant to list the new officers elected on June 21st. President: R. Colson (Innoxa) Vice-Presidents: M. Delobel Treasurer: General Secretary: L. (Gattefosse S.A.)

BOOK REVIEWS PAPER CHROMATOGRAPHY--A LAB- ORATORY MANUAL, by Richard J. Block, Raymond Le Strange, and GunterZweig. Academic Press, Inc. New York, 1952. 195 pp. Probably in no other branch of modern analytical techniques is a laboratory manual more needed than in the branch of paper chro- matography. It is a branch of analytical chemistry that has been expanding rapidly in the past five to ten years. In the field of bio- chemistry this expansion has been particularly rapid and any researcher in this or related fields has had to make an extensive search of the original literature for information regarding the applicability of the chromatographic technique to com- pounds with which he may be work- ing. As the authors state in the fore- word "The object of this monograph is to provide a readily accessible source for some of the many uses and adaptations of paper chromatog- raphy that have appeared since the publication by Consden, Gordon, and Martin less than 10 years ago." The book is divided into twelve chapters. The first chapter, which is the Introduction, presents some simple but fundamental rules to be ex. nployed in chromatographic practice. The second chapter deals with the theory of chromatography, as worked out by Martin and Synge, based on its similarity to distilla- tion with fractionating columns. The theoretical aspects have been minimized, because the book is Pcrincipally of practical nature. hapters 3 and 4 are concerned with General Methods and Quan- titative Methods, respectively. These two chapters are probably the most important to the inexpe- rienced worker, as they present the various techniques devised for paper chromatography. Chapters 5-12 discuss the general directions and experimental proce. dures used in analyzing the various groups of compounds that have been investi- gated by the paper chromatographic technique up until January, 1952. Numerous tables of Rs values are included in these chapters. The authors have crowded a large body of literature into a small book, and some descriptions may appear too brief for clarity. For- tunately they have an extensive bibliography to which the reader can refer. Some typographical er- rors have been noted. On page 31, Fig. 12 depicts a diagram of a light source for the densitometer but not for the densitometer described. On page 163, paragraph 2, is the elec- trographic cell used by Strain shown in Fig. 1 or in Fig. 2 ? A book of this type is a necessity for the average laboratory that is at all concerned with paper chroma- tography.roW. W. Er)iVlA•r, Evans Research & Development Corp.
