While the title of this book (the second in a coiitemplated corititiuing series) implies a restricted biochemical interest, the prcparations and chemicals described possess considerable pharmaceutical interest. I n general, each monograph includes a clear aiid concise statement of the principle involved, the starting material required, the procedure to be followed, properties and criteria of purity of the finished product, and other methods of preparation. Methods of preparation which are adequate are described for the following products: Cytochrome C ; Cucurbit Seed Globulin ; Oxycasein; Phosvitin, Sodium Salt; Crystalline Lactate Dehydrogcnasc; Sodium Pyruvatc; Phosphoryl-enolpyruvic Acid ; 1-o-Glycerophosphoric Acid ; Glucose-B-Phosphate; C" Uniformly Labeled Sucrose; Fructose-1, 6Diphosphate; myo- and ur.-epi-Inosose-Z; lnositol Monophosphate; DL-Ghtamic Acid Monohydrate; L-Aspartic Acid ; S-Benzyl-1-Cystcinylglycine ; aMethyl Carbobenzoxy-L-Glutam;Fte; N-Carhobenzoxy-y- 1 - Glutanlyl - S - Renzyl-1 - Cystinylglycine; Glutathionc; Rcduccd Diphosphopyridine Nucleotide; Phosphorylcholine; Oleic Acid arid Methyl Olcatc; and Methyl Ricinoleate. Acids and Rases. Their Quantitative Behaviour. By R. P. BELL. John Wiley and Sons, Inc., 90 pp. 17 x 11 cm. New York, 1952. vi Price $1.50. The aim of the author of this little book is to present a brief and unified account of the applications of acids and bases through a wide variety of chemical problems. The first two chapters, elementary in nature, cover material on the nature of acids and bases and acid-base equilibria in water which is readily available from other sources. The behavior of acids and bases in nonaqueous solvents is discussed in chapter 3 arid interionic attraction in acidbase equilibria in chapter 4. Chapter 5 discusses briefly and clearly the correlation of acid-base strengths with molecular structure, and the catalytic powcr of acids and bases in many rcactions is covcrcd in the sixth chapter. Geiicrcil references to books or review articles are listed a t the end of each chapter. The book is provided with an adequate index, and its publication rcprcsents an interesting addition to Mcthuen's Monographs on Chemical Subjects.
Review of Phurnzncy. 7th ed. By GEORGEW. FIERO. John Wiley & Sons, Inc., New York, 1952. 122 pp. 16 x 23.5 cm. Price $3.25. The object of this hook is to furnish condensed information relating to drugs in the latest editions of The United States Pharmacopeia and The National Formulary. I t may he used to advantage by pharmacy students in preparing for examinations and by the pharmacist as a reference book. I t is doubtful,
however, that the book can possess the significance or serve the purpose that it might have in 1927 when the first edition was published.
Symposium on Radiobiology. The Basic Aspects of Radiation Efects on Liuing Systems. Ed. by JAMES J. NICKSON. John Wley & Sons, Inc., 465 pp. 15.5 x 23.5 New York, 1952. xii cm. Price $7.50. A Symposium on Radiobiology was held a t Oberlin College in June, 1950, in an attempt to present a rCsumC of thc statc of knowledge of the field a t that time. This book reports the 23 papers presented to the Symposium, covering four separate phases of radiobiology. These four separate phases include (1) a survey of thc physical interaction of ionizing radiation and matter; (2) an explanation of the chemical changes arising from the transfer of physical energy; (3) an examination of the biochemical effects; and (4) a discussion of the changes occurring in living tissue. The authors have attempted to give full development to each subject from its basic aspects to the most complex phases.
A Guide to the History of Science. By GEORGE SARTON. Chronica Botariica Co., Waltham, Mass. ; Stechert-Hafner, Inc., New York; 1952. xviii 316 pp. 16 X 23.5 a n . Price $7.50. This book is concerned with all branches of the natural and exact sciences. It is divided into two main parts, the first arid shorter of which is based upon lectures explaining the purpose and meaning of the history of scieuce which were delivered by the author in several European universities. The secorid and much longer part of the book presents a bibliographical sumniary prepared for the guidauce of scholars interested in any phase of the history of science, which can be used to advantage by historians of science. Thc author, who is editor of Isis and Osiris and a professor in Harvard University, clearly stresses the fact that historians of science must know both science and history, and that knowledge of one is insufficicnt without an understanding of the other. The bibliographies on chemistry, mcdicinc, and pharmacy and the complete list of periodicals devoted partially or entirely to the history of science should appeal particularly strongly to thc student of the history of pharmacy.
