The Polarographic Method of Analysis. By OTTOH. MULLER. Chemical Education Publishing Co., Easton, Pa.. 1951. xii 209 pp. Illustrated. 13.5 x 21 cm. Price $3.50. Chemists who have been interested in using the polarographic method of analysis will recall that the author of t h i s book published a series of five articles in 1941 in the Journal of Chemical Education, which were eventually reprinted and bound together to constitute the first edition of Polarographic Method of Analysis. The purpose of the first edition was, according to the author, “to present a simple account of polarography in a form which can be used by teachers and students of physical chemistry as well as in advanced courses of analytical chemistry.” The aim of the second edition is essentially the same, but t h i s edition has been thoroughly revised, with the incorporation of recent developments to polarography. The book is divided into eight chapters, an appendix, a list of general polarographic references, a list of experiments, and an index. In the first chapter a brief review of electro-analytical methods is given, mainly to emphasii the fact that Professor Jaroslav Heyrovsw, of the Charles’ University, Prague, developed an electrochemical method of analysis quite distinct in its principles from others. In Chapter I1 the essential apparatus required in polarography is described. The fundamentals of quantitative analysis, included in Chapter 111, has been expanded by adding sections on the kinetic and catalytic currents. More emphasis on reactions in poorly buffered solutions has been incorporated in Chapter IV on the fundamentals of qualitative analysis. In Chapter V polarimetry has been treated separately. A brief description of some recent developments such as ditferential, derivative, and oscillographic polarography has been included in Chapter VI. The applications, discussed in Chapter VII, have been considerably increased in scope. Chapter VIII is entirely new and is devoted to suggestions for practical polarography, with special attention given to the characterization and selection of capillaries for the dropping mercury electrode. The typical experiments listed serve to illustrate the points discussed in the preceding chapters. They can be carried out with very simple equipment ordinarily available in modern student laboratories of physical and analytical chemistry. Polarographic methods applied to analytical pharmaceutical problems have been quite numerous during the past ten years. It seems safe to predict that the polarographic method may continue in the future to be applied to additional analytical problems of a pharmaceutical nature. There can be no doubt but that this second edition of The Polarographic Methcd of Analysis will aid anyone interested in learning the fundamentals of polamgraphy.

Qualitative Arzneimittelanalyse. By HANSM W E MANN and ADOLP BURGIN. Ernst Reinhardt Verlag AG., Basel, Switzerland, 1951. 285 pp. 13x 21 cm. This book, according to the authors, is intended mainly for the professional pharmacist and the student of pharmacy. Its purpose is to enable the user to carry out simple analytical procedures required in the practice of pharmacy. The tests outlined and the procedures described are all designed so as not to require the use of special and expensive equipment. The book is divided into three main parts. The first part covers general methods of separation, the second part describes methods for the isolation of drugs from the dosage forms in which they are usually employed, and the third part describes characteristics and methods of identscation of drugs previously separated and purified. The book probably offers little of interest to pharmaceutical chemists in the United States. A large proportion of the drugs for which identification tests are given are included in either the United States Pharmacopeia or the National Formulary, thus making a supplementary book limited to simple identification tests unnecessary. Salben, Puder, Externa (Die ausseren Heilmittel der v. CZETSCHMedizin). 3rd ed. By HERMANN LINDENWALD and FRIEDRICH SCHMIDT-LA BAUXE. Springer-Verlag, Berlin, 1950. xi 4- 492 pp. Illustrated. 16 x 23.8 cm. Price DM 36. The main object of this book is to present information on the use of ointments. In the general part are presented an historical review and information on the basic materials of ointments used in dermatology. In this section will be found a classification of ointments according to their constituents. The second part of the book is devoted to therapeutics involving the use of ointments and comparable external preparations. In the third part various powders and powder bases are discussed. Of especial interest are the suggestions made for the choice of a powder or an ointment in the treatment of diseases of the skin. In the final chapter of the book industrial problems in protective skin preparations and methods of protecting the skin of workers from industrial poisoning are presented. The book is provided with a useful author and subject index. Annual Report on Essential Oils, Aromatic Chemicals, and Reluted Materials. 1947-1948. Schimmel and Co.,Inc., New York, 1951. 125 pp. Illustrated. 15 x 23 cm. Price in U. S. and Canada, $3; Elsewhere, $3.25. The latest Schimmel Report has recently made its appearance covering two years (1947-1948), instead of one, as has been customary in previous editions. This year’s edition offers the usual record of
