81 BOOK REVIEWS Chemotherapy of Infections H. 0. J. COLLIER. New York,John Wiley and Sons, Inc., 1954,248 pp., $4.00 This small volume describes the general aspects of chemotherapy and the various groups of chemotherapeutic agents. Dr. Coffier discusses the application of chemical substances used against microbes infecting the body, and though he admits that his book ignores many interesting substances, the chemical agents which are included are those in which important results have recently been achieved, and those compounds and experiments which clearly show the basic principles of chemotherapy and the historic development of these principles. Dr. Collier adequately illustrates the newer approach to therapy which may be called “chemical pharmacology.” The subject matter makes very interesting reading and does not demand a great background in either chemistry or microbiology. This book will prove interesting and instructive to those who have the authority to prescribe these drugs as well as those who wish to keep informed on the progress of a neighboring science. A Practical Manual of Medical and Biological E. Guaa. New York, Interscience Publishers, Staining Inc., 1954, Techniques 320 pp. $4.00 This is an excellent manual dealing with preparation of material and staining procedures in all phases of microbiology. It is well written, giving the maximum information and directions in concise terminology. The appendix contains formulas for stain preparation, tables of stain solubilities, and tables of refractive indices of the solvents and oils used in microbiological work. This book is highly recommended as the laboratory supplement to the standard texts on microbiology and cytology. Statistical Analysis in Chemistry and the Chemical Industry C. A. BENNETP and N. L. FRANKLIN. New York, John Wiley and Sons, Inc., 1954, 724 pp. $8.00 This book has been sponsored by the Committee on Applied Mathematical Statistics, National Research Council of the National Academy of Sciences. The authors present those aspects of applied mathematical statistics which will be continually useful to both the chemist and chemical engineer. The subject matter is developed very completely with the theoretical basis, derivation of the methods, and the computational procedures. The reader is given a good background of mathematical theory so that he has a firm basis for judging application. The selection of methods is aimed specifically at the chemist and the examples given are taken from many branches of chemistry and chemical industry. The more recent developments in applied mathematical statistics have been included, with illustrations of their application to chemistry.
