her from chloroprene, are given; m u d information of value is t o be found in the charts of type formulas and uses as well as the tables on essential oils and enzymes; the readinn " references are numerous and excellent; and the chapters on plant and animal pigments, enzymes, vitamins, and hormones, although somewhat new to the pure organic field, show that the authors are expending considerable effort to keep abreast of the times. The hook is remarkably free from errors. Reading is easy t o a great extent because of the numerous structural formula equations which, though space-consuming, are of ready interpretation. However, a less frequent use of the parenthesis would allow one to follow the trend of the thought with less difficulty. C. A. B ~ H L E R Tae Umvsarlrv oP T s w ~ s s s s a KNOXVILLE, TBNN.

Volumes I to 1X, inclusive. of the annual publication "Organic Syntheses" have been thoroughly revised, slightly erpanded, and published in one volume. The new directions are for adipic acid, benzilic acid, cyclohexylcarbinol, dibenzoylmethane, d-glutamic acid, glycine, dlmethylethylacetic acid, pentaerytbritol and n-propyl benzene. I n the reviewer's opinion the outstanding feature of the collective volume is its indexes, of which there are five: a type of reaction index, a type of compound index, a formula index, a n illustration index, and a general index. Each index is conveniently marked by a thumb index tab, making its use convenient and rapid. I n connection with this well-known publication, i t is almost superfluous to add that the methods described for the preparation of various organic substances have

been carefully checked in a laboratory other than that of the contributor. NA-N L. D ~ K E u s ,.,T .Y

The purpose of this book is to give an elementary survey of the field of volumetric analysis as it applies t o the determination of both organic and inorganic substances. It does not attempt to give directions for nor to discuss the preparation of the solutions for the analysis of technical and difficultly soluble substances. Chapter 1is in the nature of an introduction to the subject and describes the preparations of some simple acid and alkali standards and their uses in a few of the more common volumetric determinations. Chapter I1 is also preparatory and deals especially with the subject of accuracy, giving a number of practical hints about procedures and manipulations. A brief discussion$ given here of chemical equivalence and the method of calculating the results of the analysis. The next four chapten deal with the subject matter of the various volumetric procedures including the preparation of standard solutions and methods of analysis of various substances. Cbapter 111 takes u p the subject of acidimetry and alkalimetry. Chapter IV deals with oxidimetry, not including the iodimetric processes which are treated separately in Chapter V. Chapter VI deals with the volumetric a red pita ti on processes. Chapter VII, the last one in the hook, is a synopsis in which a more complete list of substances is arranged alphabetically, each substance being followed by a brief outline of the method or methods appropriate for its determination. While the subject matter is handled in an elementary way, the ground covered is considerably broader than that which

is usually met in a text designed to fit the needs of an elementary course given in the average American college. The theoretical dkussions, while not extensive, are accurate and are presented in a straiihtforward way so as t o be easily understood by beginners. The author, of course, presupposes a good foundation in general chemistry such as most colleges give. The methods described and the theoretical treatments are up to date. The book bas the merit of being teachable as well as accurate. The author clearly demonstrates that he has had a cnnsiderable experience in teaching beginners, for he appreciates the value of a simple and direct method of presenting new material to the uninitiated. The reviewer would have been better satisfied if there had been added another chapter dealing with the preparation for analysis of a number of different technical and complex substances. This addition, together with some well-placed specific references to more extensive theoretical discussions, would have made the book adaptable t o the teaching of a more advanced course in volumetric analysis. The book should find a wide field of usefulness. It also deserves a better quality of paper and binding. H.W. BRusAKER KANSASSTAT=COLLBE& MINH*TT*N. K*NS*S
1932 Illnstrierter Apotheker-Kalender. FRITZFEKCEL. Seventh Year. Arthur Nemayer, Mittenwald (Bayern), Germany, 1932. Appr. 100 pp. 16 X 25 cm. Postpaid M4.50. The illustrated calendar of the apothecary is an interesting and perhaps unique volume. I t attempts to depict by means of numerous illustrations and captious the historical development of pharmacy and its allied sdences. The volume is conveniently arranged in the form of a calen-
dar of the current year. The days of the month are so arranged that there are spaces for daily notations. On each page, which includes three or four days, are illustrations of some event of interest in the history of the guild of the apothecary. Among the illustrations which are particularly impressive are Gregor Mendel, the famous iatrochemist Johann Baptiste van Helmont, and a reproduction of the classical painting "Der Alchimist." Throughout the volume there are numerous illustrations of Christ shown as an apothecary. Many of the saints including Joseph and Mary are shown in the rile of the apothecary a s represented in ancient paintings. The illustrations set forth in no uncertain manner the high esteem in which the apothecaries' guild was held in the past and how its history is interwoven with that of chemistry and medicine. JR.
