The main portion of the book is divided into four sections. I n Part I are discussed simple calculations, such as addition, subtraction, multiplication, and division, with numerous examples. Part I1 covers special aids in multiplication and division such as logarithms, the logarithmic sIide.de and the calculating machine. Part I11 deals with chemical calculations and their algebraic formulation and covers simple gravimetric analysis, volumetric analysis, indirect analysis of two- and three-component systems, critical examination of errors, calculations of analyses of complex mixtures such as rocks, omplea salts, and water, and the calculation of gases. Part IV deals with nomography and includes a review of the literature. The subject matter of the book should certainly be given careful consideration by all teachers of courses in stoichiometry. Its use as a textbook will necessarily be limited t o classes that have had a thorough grounding in German. G. E. F. LUNDELL

form of expression and subject matter, which greatly improve the text and bring i t down t o date. Part I (323 pages), which is devoted t o the open-chain compounds, begins with the usual chapter on "Composition, Purification and Analysis of Organic Compounds and Deduction of Formulae." followed by chapters on hydrocarbons, halogen derivatives, etc., with only slight differences in the order and number of chapters from the older edition. I n contrast with some of the recent American texts, no reference is made t o the electronic theory in explaining organic reactions. What is more surprising, however, is that the Genevaiystem of nomenclature is wholly unused. The chapter on carbohydrates (24 pages) is unduly shortened, owing t o the purpose of the authors t o discuss this subject in more detail in Part 111. I n this connection i t seems unfortunate not to devote some attention t o the space relationship of the sugars, the oxide formula, etc., since many students will never see Volume 111. Part I1 continues with homocyclic compounds, t o which 170 pages are devoted.

tion of many typical compounds is described in sufficient detail t o enable a beginner t o carry out the operation by himself." Some seventy-nine preparations are described accurately, hut briefly, though the reviewer feels that their inclusion does not adequately take the place of a fuller laboratory text. Their presence in the volume may have the advantage that the student can correlate the laboratory methods with the descriptive matter in the text without recourse t o another b o o k a n effort which he sometimes fails to make. The volume has naturally been written for the English school system, with the result that the American teacher will find some of the topics t o which he might wish t o refer, such as the extended treatment of carbohydrates, terpenes, etc., in Part 111, which is to appear shortly. From the standpoint of typography the hook is a very satisfactory one. The formulas are clearly printed and the pages have a pleasing appearance. This new edition can commend itself very definitely t o the teacher who desires a well-written. accurate text containing a wealth of descriptive material correlated with the necessary discussion of group reactions and with theory substantiated by accurate ex~erimentaldata.

The book consists of essays on such topics as an Outline of Stereochemistry, Optical Activity, Geometrical Isomerism, Stereochemistry of Nitrogen Compounds, Walden's Inversion. Mutarotation, Asymmetric Synthesis, Dynamic Isomerism, Constitution of Benzene. Constitution of Diazo Compounds, Relation between Color and Chemical Constitution, Ahsorption Spectra, Synthetic Dyes, Natural and Artificial Rubber. Constitution of Chlorophyll, Chemical Action of Light, Abnormal Valency, O r-~ i n i cCom~ounds of Maz. nesium and Zinc, Organic Compounds of Lead, Keteues, and fifteen similar subjects selected from the field of organic chemistry. The essays are short, concise, and clearly written. The advanced undergraduate and first-year graduate students will find them not only interesting and instructive hut also a valuable guide t o further reading. In keeping with the peculiar purpose for which the hook was written. i t contains no references. This is to he regretted since many readers will find here suggestions which they will want t o follow t o their original source. One wonders whether the hook would not have served its intended purpose equally well if the references had been inserted. The American reader will find both the vocabulary and spelling a little unusual a t some points. CECILE. BOORD TAEORTO STAT*U N ~ Y B R E L T Y ~~
