BOOK REVIEWS At the end of the chapters are generous lists of well chosen review questions. The text contains a wealth of well-arganized information, much of which would be of value to nurses. A competent instructor will easily compensate for the omissions noted. ARTHURL.WILLIAMS San Jose State College San Jose, Cdifornia Nomography

The author's claim, "The present volume is intended to fill the need for a. book t h a ~comhines the discussion and methods of construotion with a thorough presentation of the underlying theory," seems to be well substantiated. The reader moves rapidly through introductory chapters on determinants, nomographs, and projective transformations to a more sophisticated paoing of matrix multiplication and into the latter half of the book treating the representation of equations involving more than three variables, empirical nomography, "Kellog's method" and nonprojective transformations. There are no lists of practice problems, but the book is sure to he a

This is another book in the "General and Industrial Chemistry Series" edited by H. M. Bunhury. Following the pattern of the other members of this series this volume presents "a considered appraisal of the progress made, particularly over the last two decades, in the. . subjects of d i s infection, sterilization and antisepsis." The book is divided into six parts: (1) Theory of Disinfection and Methods of Testing, (2) Methods of Sterilieation, ( 3 ) Air Disinfection and Sterilization, (4) Disinfection of Viruses, (5) Chemical Disinfectants, and (6) Preservation and Preservatives. There are a total of 17 chapters, each of which is excellently written. Each topic is prefaced by an interesting historical passage. The tables and figures are adequate. The terminology and definitions throughout are consistent. The chapters pertaining to Chemical Disinfectants are of interest to the chemist in that the aotions of nhenals. dves.

This manual was written to acoompany two texts written by the author, "Fundamcntals of Inorganic, Organic, and Biological Chemistry," written exchlsivelg for nurses, and "Twentieth Century Chemistry," suitable as a text for a oneyear terminal course. In dealing with unsaturated hydrocarbons, solutions of bromine and iodine are added to acetylene. Due to an anomaly, acetylene is a very poor choice for this reaction since it reacts too slowly to be detected by a beginning student. With iodine, there is no reaction. No comparison in the relative rates of reaction of halogen a n saturated and unsaturated compounds is inoluded. A solution of (Catinued on page A646)
