hut two minor examples: the omission of a valence bond in the ethylene formula at the bottom of page 131,and Nar instead of 2 Na on page 52. Study questions follow each chapter and afford ample opportunity for the student to review and apply the principles of the text. These questions and the several flow-sheets illustrating the genetic relationships of various groups of wmpounds constitute a very valuable and useful feature of the work. Print and paper are good, and the hwk is well bound. UWIYBESITY 01 MARYLAND

THE FOUNDATIONS OF NUTRITION.Mary Swarte Rose, Ph.D., Professor of Nutrition, Teachers' College, Columbia University. The Macmillan Co.. New York City. 1933. Second 630 pp. 101 Figs. 13 X 20 cm. $3.00. edition. xi

The author states that the "hook is written for those who vish to live more intelligently. An effort has been made to present within a small space some of the fundamental principles of human nutrition in terms which call for no highly specialized training in those natural sciences upon which the science of nutrition rests." That Dr. Rose has been successful in presenting the fundamentals of human nutrition in an interesting and effective manner is probably best indicated by the fact that "Faundationsof Nutrition" has undergone many reprintings andone completerevision since it was first published in 1927. The present book is rewritten and enlarged but follows the same general plan that characterized the first edition. A comparison of the first and second editions shows that the 12 chapters of the former have been expanded to 26 chapters in the latter. This has been done by the inclusion of outstanding researches published since the appearance of the first edition. Separate chapters are now devoted to each of the vitamins. The appendix (nine tables and one chart) has been revised and enlarged. From the standpoints of b i n d i i , general appearance, size of pages, quality of illustrations and typography. the second edition appears to he a distinct improvement over the first edition. The reviewer considers the hook unique in that it discusses the fundamental principles of human nutrition in an elementary hut authoritative and scientific manner and a t the same time answers most of the important practical questions regarding their application to fwd selection and diet construction. Dr. Rose's new text will undoubtedly continue to hold the unique position it has achieved for itself as the outstanding elementary textbook on human nutrition in the home economics field.

The hook contains chapters on the principal constituents and functions of food; general aspects of food control; milk; milk praducts other than butter; eggs; meats and meat products; poultry, game, fish, and shellfish; grain products; vegetables; fruits and fruit products; nuts; edible fats and oils; sugars, sirups, and confectionery; food adjuncts such as baking powders, spices, condiments, flavoring extracts, tea, coffee,sMt drinks, etc. The final chapter deals with some aspects of food economics. There are appendices on the food and drugs act and related regulations and decisions; meat inspection law and regulations; calcium, phosphorus, iron, copper, and manganese contents of food; and fwd products as sources of vitamins. Fwds are discussed from a standpoint of pmduetion and handling, composition, adulteration and inspection, standards of purity, dassifieations and detailed proximate composition. The nutritive qualities of each fwd are presented and their place in the diet is discussed. In the case of all manufactured fwds the processes of manufacture are briefly discussed. In connection with each food a selected bibliography includes all the mare important authoritative sources of information. This new edition is thoroughly up-to-date and represents a ready source of reference for an immense number of facts of in-
terest to teachers and students. I t will be heartily welcomed wherever nutrition is taught.
MA~ACT~R oaE SODA. Te-Pan Hou. Ph.D. American Chemical Society Monograph No. 65. The Chemical Catalog 351 pp. 129 Tables. Ca., Inc., New York City, 1933. xiv 72 Figs. 15.5 X 23 cm. $8.00. The purpose of this monograph, a c w r d i i to the author, is to present material relating to the ammonia soda industry, which bas been previously withheld from the public by the manufacturers. The author realizes the lack of technical details based on madern practice in the available current literature, and in preparing his work draws his material mostly from his own experience and investigations. The subject is approached from the practical side, hut the theoretical background receives serious consideration. Every phase of the industry, with the exception of the design and construction of plants, is treated in the greatest detail. One of the most outstanding contributions in this monograph is the wealth of calculations illustrating theoretical discussions and unit proeess operations. The chapter on chemical analyses and tests in the alkali industry is detailed and complete. From the standpoint of chemical education this monograph should serve as an admirable source and reference book in this division of industrial chemistry. L B a r O a UNIYBPSITY c.

DIE TECANIKDER C A E ~ S C A E N OPERATIONEN.Dr. Walk? Bade?, Chemical Engineer, Basel. B. Wepf & Cie.. Basel, 1934. iii 416 pp. 77 Figs. 16 X 24 cm. Paper cover, frs. S. 18; cloth cover, frs. S. 20. The book is an elementary treatise of processes related to chemistry. There are no references to the work of others in dosely allied fields. The author states that "Es ist eur fort laufenden Lecture frir j6ngcre Chnniker bestimmt. .Es handell sich darum, die en der Hochschulc getrcnnt crworbencn Kenntnisse in Chemie . . . " By comparison the bwk may be said to stand between certain texts in English, intended for high-school and early college students, and those more advanced texts which recently have appeared. The treatment is distinctly of mechanical processes and devices. The author adheres closely to his thesis that the book is not suoobsed to be an advanced text. Solution Operations are dhait with in four chaptersdiuolving, extraction, precipitation, and crystallization: Mixing Operations in three chaptersmiring, kneading, and stirring; Separating Operations in five chaptersair flotation, washing, sedimentation end decantation, sifting, filtering, centrifuging,and pressing; technic of solid material in five chapters-storing, crushing and grinding, molding, transportation, and weighing; Technic of Liauids in six chaDtersstorine. -. trans~ortation. emulsifvine . solutions of liouids in rases. " . and measutinn of liauids. Technic of Gases is treated in six chapters-,loring, solution of gases in liquids, desiccating, compressing and liquefying, tranoportation, and measuring; Heat Transference in four c h a p t e r s refrigerating, heating, fusing, and calcining; Evaporation Operations in four chaptersvolatilizing, evaporating to dryness, distillation, and sublimation. There are four chapters on isolated topics--autoelave technic. high-pressure technic, technic of catalysis, and automatic control of operations. The treatment is logical and in due consideration of the dass of invited readers, subdivisions of thechapters are many and helpful. One illustration will suffice. In chapter thirty-nine on distillation, seven sub-topics are given, which aid one in selecting quickly desired information. The reviewer is impressed by the dearness of the drawings, including evident success in representing operations. Except for the absence of an index, the book appears to fill satisfactorily a place in its intended field. The mechanical make-up of the book is attractive. Good quality of unsized paper, large, dean type, outstanding headings and subheadings are a few of the commendable features. WBSTVIROINIA UNIYBBSITY FRIEND E. CLARK M o a o ~ m a r w W. , VA.
