For many years the Treadwell-Hall Quantitative Analysis has been recognized as a standard reference book on methods of quantitative analysis. I n the new edition, the material has been revised completely and many older analytical methods have been discarded in favor of newer and better ones; but the main outline of the book remains unchanged. An Introduction comprising the first 54 pages contains a description of weights and weighing, filtration, sampling, and other general analytical processes. This is copiously illustrated and provides a wealth of practical details of laboratory technic. Part I contains 245pages devoted to the gravimetric determination of the metals, grouped according to their chemical properties. Several methods are usually given for the separation of the element under consideration from others most like it, and its final determination. The last 160 pages of this section are devoted t o the gravimetric determination of non-metallic elements and radicals. I n addition to the analysis of inorganic substances, a number of organic methods are taken up. These include combustion for carbon and hydrogen, the Cariusmethod for halogens, and Dumas' method for nitrogen. Part I1 contains 218 pages devoted to volumetric analysis. A description of the standardization and use of volumetric apparatus is followed by a brief discussion of neutralization indicators and the methods of acidimetry and alkalimetry to which they are suited. The next subject, comprising half of this section, deals with the theory of oxidation and reduction in solution and the processes based upon these reactions. The last section deals with precipitation titrations. Part 111 consists of 80 pages devoted to Gas Analysis. In addition to the analysis of illuminating gas and other hydrocarbon mixtures, the analysis of inorganic gases like chlorine and sulfur dioxide is taken uo. ~~, The next 4 J ~ , ; i g tcontain s a largc collcctiun of convcrsiun tnbler and tal,lc< givinr: the dmsiries oi s ~ l u t ~ o n wul c the properties of compound$ urrful in :m:tlgticdl prurcdurcs. The I.rst 50 p3grs of the hook are taken up with a very complete author index and subject index. The volume is clearly printed in good type on good paper; well illustrated and attractively bound. This book can be recommended as an excellent reference work for the advanced analvtical student. teacher. or research worker who wishes soecific information on analvtical orocesses.

Kwhler has succeeded in compressing into one moderate-sized volume. The chapter on the economics of power generation, though short, is very good. The review of theoretical electrochemistry could have been omitted. in view of Creizhton's work. or at least " ~ condensed to s few essential definitions, formulas, and concepts. If this book were intended to be self-contained, it could well be rearranged and expanded t o include more of the principles utilized later. Primary cells and especially secondary cells are handled very well. A fuller discussion of fuel cells, although a t present of theoretical interest only, might well be included. Electroplating, electroplating solutions, and electrarefining are discussed with unusual detail. The same may be said of electrometallurgy, both of aqueous solutions and fused salts. The discussion of the electrolysis of alkali halides is satisfactory. A little more on the theoretical principles involved might help. The chapters on electrolytic oxidation and reduction and on oxygen and hydrogen production are very good. A brief, though satisfactory discussion of corrosion is included. Unusual in such works is the chapter on electroanalysis. The chapters on electric furnaces and their uses in the metallurgical and nonmetallurgical industries are noteworthy. Electronics are treated much more fully than is common and this is quite desirable. The chapters on ozone production and nitrogen fixation are satisfactory. Separation by electrical means is very fully discussed. The chapter on miscellaneous electrochemical processes is something new and well worth including. The book includes 35 tables of useful data and an abundance of references. Operating details are very full. The illustrations are excellent. Both subject and author indexes enhance the value of the work. Type, format, and style of the author combine to produce a most attractive book. I n conclusion the reviewer desires t o compliment the author and publisher and t o recommend this book without reservation I t is realized that space considerations forbid the inclusion of certain material mentioned above, so no adverse criticism is intended. Electrochemical workers will need this work and every teacher of the subject should consider carefully its use as a teat MALCOLM M. HARINO ~~

The first edition of this textbook was published in 1926, and the author has thoroughly revised it in order t o bring it up to date. This text places especial emphasis on (a) the historical development of organic chemistry; (b) the deduction of structural formulas; and (c) the correlation of academic, technical, and economic phases of organic chemistry. Part I of the hook is devoted to the "Historical Development" of chemistry. While much of this material does not deal with N o ~ r ~ w s s Ur lsr r~v~ n s r r ~ organic chemistry, the author justifies its inclusion by pointing EVANSTON.
