are normally developed for idealized situations and this is something that makes the book different. However, it can be argued that this particular presentation involving the use of friction terms in classical thermodynamic relationships may lead to confusion rather than c l e a r understanding. An attempt is made to treat another area which is not considered in most thermodynamic texts. This is the section devoted t o experimental apparatus for making thermodynamic measurements. It is rather aketchy and could not serve a student as a source of detailed information on experimental techniques in thermodynamics. It is difficult t o evaluate tte book for possible olsssroam use since much of the choice of a text depends on an instructor's tastes. It can be stated, however, that in view of the thinking of the Ad Hoc Committee on Engineering Science8 which was created by the American Society for Engineering Education (the committee reports have not yet been published), this text falls short of what might he called the optimum content of a course in engineering thermodynamics. The text has value as supplemental reading material in a. course. Its unique approach will certainly stimulate thought and discussion. Some of the derivations are new and different and while they have no fundamental importance in themselves, they may be of interest t o advanced students. LAWRENCE N.

THISthird and last volume completes the authors' endeavor to compile a comprehensive, up-twdate treatise an volumetric analysis. The Volume 3 eomplements Volume 2, "Titrstion Methods: Acid-Base, Precipitation and ComplexFormation Reactions," second revised edition (194i), in covering the practical principles of volumetric analysis. Originally, t,he practical principles were treated in a single volume, Volume 2, "Volumetric Analysis," by the senior author, and translated into English by Dr. N. H. Furman (1929). However, in writing the modern version of this text, the authors found it ncccvnry to prqnrc two vcdurnr~c. I IE rr.$soni c w rhis r h n p is srored !n me I'rriwr V n l m w 2, arrcmd rdirwn (1917 .

thoroughnws i t has been found advisable to prepsro two volumes instead of the one originally planned. Oxidstion-reduction method8 have therefore been reserved for Volumc 3." The validity of this ntatement is tcsted by comparing the present Volume 3 with the original Volume 2 (19'29). Volumc 3 is divided into 15 chapters and contains approximately 700 pages and 2350 numbered references. The original Volume 2 contained only nine c h a p t,era or ahoitt 240 pagcs which were all& ted to the discussion of volumetric mcthods involving oxidation-reduction reactions, and (32; numbered references. The numbered references of Volume 3 date from 1835 to 1956, inclusive, and likel3contain all of the important, pertinent references of this spanof 121 years. To accomplish their objective, the authors prenent, in Volume 3 a critical review of those methods which they consider to be the more important and useful titrzt.ion met,hods involving oxidationreduction reactions. After briefly discussing Reactions, Indicators, and Gonera1 Techniques in Oxidation-Reduction Titrstions (Chap.I), chapters are allotted to the treatment of the following: Potassium Permanganate sa s. Volumetric Reagent; Onidimetry with Permrtnganate; Oxidimetry with Ceric Salts; Potassium Dichromat,e as Oxidizing Titrsnt; Iodometry, Reagents and Their Standmdieation; Iodometric Determination of Inorganic Substances; Iodometric Determination of Organic Compounds; Determination of Water with Karl Fischer Reagent; Potassium Iodate as Oxidizing Titrant; Oxidation of Organic Compounds with Periodate; Potassium Bromate as a Titrimetrie Reagent; Oxidation with Hypohelites; Titrations with Iran(II), Titsnium(III), and Other Strong Reducing Agents; and Miscellitneous Titrants. Each volumetric reagent is treated in respect to preparation, stability, standardization, and use. Standards, indicators, methods of standardization, and the determination of end points are described and evaluated. Each chapter contains an abundance of procedures and notes, printed in small type, which are brief but adequately treated. Ample references t o source material is given. Finally, s. complete author index, containing appraximiltely 2500 names, and a. subject index complete the volume. Like its companion, Volume 2, items listed in the subject index m e identified with the method of determination. Although this volume is not an elementary text, it is mitten in s clear and concise manner; and it should prove valuable as a reference text. Some emphasis is placed on theoretical principles even though they have been treated in detail in Volume 1 of this series. By the publication of this third and last volume of a n excellent series on volumetric analysis, the authors have not only satisfied the present need of a, modern, upto-date treatise, but have made a. valuable contribution to the review literature of the subject.

UNDERthe title of this book is the added phrase " ~ i t hspecial reference to the chemical industry." The methods expounded, however, are just as applicable to certain types of academic resewch as they are to industrial research and development. This third edition of a n outstanding work has about two dozen more figures and over 100 more pages than the previous edition [reviewed in J. CHEM. EDUC.27, 582 (1950).] Following are the headings and the number of pages in each chapter: (1) Introduction, 6 , (2) Frequency Distributions, 81, (3) Averages and Measures of D i e persion, 84, (4) Confidence Limits and Tests of Significance, 18, (5) Statistical Tests: Choosing the Number of Observation~,27, (0) Analysis of Variance, 54, (7) Linear Relationshim between Two
Vitriitbles, 58, (8) Multiple and Curvilinear Regression, 66, (9) Frequency Data and Contingency Tables, 86, (10) Control Charts, 88, (11) Sampling and Specifications, 87. Useful tables collected in the back include probability points for the following distributions: normal, ehisquare, student's 1, and variance ratio. Chapters 2, 3, 9, and 10 m e substantially the same as in previous editions. All other chapters have been revised. The material in Chapter 5 appears for the first time. It is the style of this book t o follow the discussion of a statistical ttechnique with an exi~mple drawn from a problem met in actual practice a t Imperial Chemical Industries. The use of such examples is a splendid feature and eases the way for chemists to learn statistical methodology. Although this book deals with applied ~t~atistics a t a n elementary level, it eantains a very large body of information. This information is well distributed, though; elementary proofs and additional computational details are relegated to appendixes a t the ends of the chapters. The uninitiated will find that considerable atudy and practice will be necessary if he is to derive maximum profit from the methods given. Nevertheless, i t is difficult to see how the authors could do a better job of leading a beginner into the subiect. "Statistical Methods in Research and Production" is highly recommended to those chemists who must deal with experimental data and who would like a smooth introduction to atatiat,ics.lnnnlv~is.
