Book Notices Industrial Detergency. Edited by WM. W. NIVEN, Jr. Reinhold Publishing Corporation, New York, 1955. 340 pp. 16 x 23.5 cm. Price $8.75. This book is prepared b y a group of experts, each of whom is experienced in a specific industry, and it offers a thoroughly modem and practical treatment of the methods, material, and equipment useful for industrial cleaning. The book presents information on the composition of detergents for special purposes, their applications, and factors that determine the choice of a particular detergent for a specific job. The first three chapters comprise an introduction, a discussion of the fundamentals of detergency, and an unusually clearly presented description of modern detergent materials. Subsequent chapters cover detergents used in the laundry industry, in dry cleaning, in textile processing, in the manufacture of foods and beverages, in the dairy industry, for dish washing, and in the metal industry. I n the final chapter general industrial cleaning is quite thoroughly discussed. While the pharmaceutical industry is not specifically covered, there is much in this book that can be adapted t o the needs of this important activity. The value of thc book as a guide t o the choice of a suitable detergent and methods of using it is enhanced by many references t o the original literature. The book is provided with an author index and a very adequate subject index which makes it possible t o locate information on any particular subject very conveniently.
arrangement of the nucleic acids, and in this treatise the editors have attempted t o collect and summarize information at present available into a single comprehensive work. This attempt, apparently successful, has been made through the collaboration of nineteen scientists recognized as authoritative in the chemistry and biology of the nucleic acids. The book is conveniently divided into two main parts, the first of which covers the chemical aspects of the nucleic acids, and the second which will be directed toward the more biological and biochemical considerations of the nucleic acids. The chemistry of the hydrolysis products of nucleic acids is discussed in Chapters 2. 3, and 4, and their separation and estimation in Chapters 5 through 9. The two main types of polynucleotides are discussed in Chapters 10 and 11. In Chapter 12,evidence on the nature of the chemical bonds in nucleic acrds is presented, and in Chapter 13 their physical properties, including structure determination by X-ray diffraction are described. Chapter 14 includes information on the optical properties of nucleic acids and their components with a discussion on the applications of ultraviolet absorption spectroscopy that has been employed both as an analytical tool and as a basis for deductions concerning structure. Thc principal absorption spectra discussed in Chapter 14 are also reproduced, on a metric scale, on two folded sheets placed in a pocket attached to the inside back cover of Volume I. The final chapter (16)forms the connecting link with the second division of the book (Volume 11), and deals with the nucleases and enzymes attacking nucleic acid components.
