336 Of particular interest t o students and an excellent feature of this symposium are the nine review papers on the same general subjects. These constitute an excellent introduction t o these subjects as well as a fine survey for workers in the field. They have been excellently prepared by outstanding authorities in the field. As may be expected, this is the part of the hook-together with some of the papers on experimental techniques-which will be of value to college seniors. Much of what is covered here is for graduate students and research workers. This is, however, a hook which college libraries will want to have on their reference shelf. PAUL M. F Y E
graphic analysis (38 pages). It deals with the principles of the methad, apparatus, and reagents. Many epecific examples, especially of natural products, are described. The last 67 psges reoapitulate the techniques for the examination of solvents and solvent mixtures. This volume is an excellent summary of the procedures used in the quantitative analysis of organic compounds. The topics are selected with taste, presented in a scholarly manner, and well documented up t o 1952. Volume I1 of Houben-Weyl's "Methoden der organisohen Chemie. analvtische M~t,hnrlm" is a " -. ..... --.. , .contribution ib organic literature that is not only significant but outstanding.

THE attitude of the Creator toward certain operations in an* lyticd chemistry is revealed in Proverbs: "A jake balance is an abomination to ihe Lord: but a just weight is h h delight." Professors of the subject and Directors of Chemical Research are somewhat more verbose; the authors of this volume require some 984 quarto pages to disclose their feelings on analytical proeednres. The immediate inciting circumstance may he the implied threat in Deuteronomy: "But thou shalt h o e a pwfeet and jmt weight, a perfect and just memure shalt thrm havet that thy days may be lenglhaed. . ." This is good advice for anyone contemplating something more than a short career in science. The authors of this volume attempt to provide an exhaustive colleotion of the procedures and knowledge relating to the analytical techniques of organic chemistry. Careful study of this material should comfort the mind in the thought that thy days should he lengthened. The first 30 pages of this volume are devoted to the deserip. tion of the qualitative tests for elements encountered in organic substances. The next 214 pages contain a survey of quantitative procedures employed in the determination of these elements. The micro, semimicro, and macro methods m e carefully described with due attention to all variations or alternative techniques. Part I of this volume concludes with an excellent summary of the analytical determinations of some 40 to 50 functionel groups and certain atomic arrangements such as the Gmethyl and isopropylidene radicals. The organization of the information under each functional group is first, and a general description of reactions useful for the qualitative recognition of the radical is next, followed by procedures for the, quantitative determination. Each of the qualitative and quantitative subdivisions starts with a convenient r6sum6 of the necessary reagents. This section of 8ome 460 pages is very well done; it was prepared by H. Roth of the Badische Anilin und Sodafabrik with 15 collaborators who for the most part are associated with the German dye industries. It will instruct the feeble and reveal to the curious the current rtnslvtical methods of the Badische., Bever. " , and Hoeehst laboratories. Part 11. Section 1. Gas Analvsis (68 osws). describes not onlv the conve"tionnl chemical metgods of analysis but includes sho& summaries on physical methods suoh as fractional distillation, adsorption, thermal properties, magnetic characteristics, ultraviolet, visible and infrared techniques, and the use of the mass spectroscope. The last 30 psges outline specific quantitative methods for the industrially important gases. Section 2 recounts the procedures for the determination of the melting and boiling temperatures (39 pages). Section 3 is a. rather good summary of the theory interpretation, and techniques of thermal analysis (34 pages). Section 4 is a condensed summary of chromato-

THE two major sections of the book (Part I, General Problems, and Part 11, Stoichiometry) are subdivided as follows: Part I contains six chapters, viz., Introduction, Specific Gravity (Dreisatzrechnungen) "Three Weight" Calculations, or, as commonly regarded, weight to weight calculations, Percentage Calculations, and Special Problems for "Weight to Weight" and Percentage Calculations. Part I1 inoludes five chapters: Chemical Formulas, Mole Volumes, Normal Solutions, Chemical Equations, and Volumetric Analysis. There are 62 examples for which solutions and answerr: are included and 369 problems of varying degree of difficulty indicated by asterisks, *, ", ***. An important and perhaps unique feature of the book is the special consideration of calculations involved in organic preparations. This little book will be of twofold value to the undergraduate major student who wishes to acquire facility in scientific German and in chemical calculations.
