This book is evidently intended for girls and women who are obliged t o acquire in a short time some understanding of the relation of chemistry t o everyday life. It was developed by t h e author at the Minneapolis Vocational High School in connection with courses given t o nurses and home economics students. The book is divided into four parts. Part I, consisting of three chapters, han t o d o with inorganic chemirtry. The first chapter crmtain. introductory material (on the types of chemical chanze. . and on t h e oronerties of s few imoortant elements and compounds) designed to familiarize the student with t h e language and method. of chemistry, by mean. of defmitionr, demonstratlons. and experiments. The second and third chapters deal with air and water.

T h e purpose of this bookis mainly toserve ae a guide t o thore tcaehers using "Laborntory Chemistry for Girls," and t o provide them with the haek=ound which the author has developed for her o m use in connection with t h e lahoratorv manual. The result9 of t h e experiments given i n "Lahoratarv Chemistrv for Girlr" arc recorded in detail and dl~cuseedfully. Information designed to aid the teacher in her direusrion of t h e l a b o n tory work ir included. T h e book fulfils its p u r ~ pore admirably and is therefore a useful supple^ ment t o "Laboratory Chemistry for Girlr."

This work eootinver the effort undertaken by the Chemical Foundation, in co6peration with the American Chemical Society, t o popularize chemistry in its relation to our daily life. and splmdidly svpplementn the first effort of the Foundation in publishing "Chemistry in Industry." The new volume "Chemistry in Agriculture," consisting of sixteen essays by pmminrnf American agricultural chemists, brings together a wealth of information, presented for the most part in simple non-technical language. of great historical and educational valve not only t o the chemist but to the layman. I t should serve a very useful purpose as collateral reading for high~sehoolstudents, for students in courses in home economics, and for student3 in colleges offering special courses in the scienees pertaining t o agriculture. The editors have correlated the writings of the sixteen ershyirtr with consummate skill and with a minimum amount of repetition. Where repetition has occurred, for example. m the discussion of vitamins by three of the authors, i t is neither tiresome nor uninteresting, as each y author presmt. the matter from a s ~ i g h t ~dieep ent viewpoint, which, for the young rtudent and the casual reader without techoicd training, has distinct merit. Besides being a storehou~e of condensed information, this book is calculated t o arouse intense interest in the inquiring mind of the young rtudent of science, intriguing the imagination to a marked degree. Thi. is e3peeially trve of the chapters on ''Crop. and the Soil," by Dr. Thatcher, "The World's Food Factory, or the Plant in Air and Light," by Drr. Arthur and Popp. "Soil Life," by Dr. Lipman.
and "Vitamins in Human and Animal Nutrition," by Prof. Dutcher. The relation and the impmtaoce of chemical technology to progressive and ~uccenrful agriculture are forcefully set forth in several chapters, especially in those on ''Where the Nitrogen comes From." by Dr. Curtis, ''Cereal%" by Dr. Bailey. "Sugsr and Sugar Crops," by Dr. Browne, and "Permentation on the Farm," by Dr. Willaman and Dr. Gortoer. The statistical and hirtorical data given are by authoritien in their several lines of endeavor. they may be accepted without question, giving t o the volume the character of a handy ready reference. The book is well-prmted in ll-point type with 48 excellent illu~trafion~.The splendid halftoner of such pioneers in the field of agricultural chemistry as Dr. Samuel W. Johnson, Sir John Lawes. Sir Henry Gilbert, Dr. W. 0.Atwater, Dr. Henry P. Armsby. Dr. S. M. Babeoek. Dr. H. W. Wiley, and Dr. Charles A. Goessmann add greatly to its charm. The authors, the editors, and the Chemical Foundation are to be congratulated upon the production of "Chemiew in Agriculture."
