well. 1st ed. I l l pages, 5 X 7.5 inches. The Avi Publishing Co., New York, Ν . Υ., 1934. Price, $2.25. THIS book is coat-pocket size, well bound, o n good paper, with readable type. The reviewer cannot state its scope and aim more aptly than the authors have done in their introduction: "The subject has been presented in this manual primarily for the use of food chemists, although the simpler methods of deter mining Brix degree, alcohol content, volatile acidity, and total acidity can be followed by any person who has high school train ing in chemistry or physics." Certainly the subject has been presented clearly, concisely, and in sufficient detail so that a beginner in chemistry, if intelligent, could follow the directions and perform the tests. One possible criticism which the reviewer might have with re gard t o the usefulness of t h e book from a professional laboratory standpoint has again been stated b y the authors very concisely in the Introduction: "Furthermore, t h e material is presented from the point of view of t h e plant control chemist rather than from that of the food inspector who may be interested i n exam ining wines for adulteration. T h e examination of wines, etc., for adulteration is covered in most textbooks on food analysis, such as those by Leach or Woodman." As a guide, even "bible," for the man in charge of a winery the book is ideal. On account of its strictly limited scope i t is not so valuable to the analyst who is called upon to examine wines, such as might be tendered t o a state liquor board. The book contains a short, but very well-chosen, bibliography on wine and its analysis. Β. Η. KNIGHT GMELINS H A N D B U C H DER ANORGANISCHEN CHEMIE.

Chemische Gesellschaft. System-nummer 50, Eisen. 8th ed. Part 6, 254 pages, 41.5 marks. Part 7, 214 pages, 36 marks. Verlag Chemie, G. m. b. H . , Berlin, 1934. I N reviewing this text the writer has found it advantageous to make a comparison with some standard English text and has chosen for the purpose Mellor's great Treatise on Inorganic Chemistry. In subject matter t h e two are almost equally up to date. In quantity of material there seems to be little choice, as both are exhaustive. T h e paper of the German text is whiter, better glazed, and evidently of better quality; the print is smaller, yet easy to read. There is a decided difference i n the way the references are handled, and in the writer's opinion t h e German text is much better because references are placed in direct contact with the material to which they refer, while in Mellor they are placed at the end of chapters. For example, under the heading Slag Inclusions in Steel four sets of references are given, following a full discussion of the subject matter. Every phase of the text is divided up in this way. The text includes only that material which is quite u p to date (June 1, 1934). In some cases the early references have been omitted because of their unreliability. For the busy control or research chemist this i s a decided advantage, although for the man trying t o work out the development of a theory or process it would not be. Part 6 takes up first the compounds of iron with sulfur, sele nium, tellurium, and boron and then goes on to the alloys with carbon which are treated i n considerable detail. It closes with an exhaustive discussion of cementation and nitrogen absorp tion in the annealing process. Many excellent diagrams and figures are used throughout the book. Part 7 is given up to a discussion of the physical properties of pure iron and iron-carbon compounds, cniefly of t h e mag netic and electrical properties. Because of the freshness of t h e material and the excellence and availability of references, this book would seem t o be the last word on tne subject and if the worker in the iron or steel laboratory can read German, it should certainly be on his library shelves.

KOHLENWASSBRSTOPFOLB 1928-1932. Maximilian PflUcke. 695 pages. Verlag Chemie, G. m. b. H., Berlin, 1934. Price, bound, 60 marks. T H E writer reviewed the first edition of this series, entitled "Leichte Kohlenwasserstoffole," for INDUSTRIAL AND ENGINEER
ING CHEMISTRY several years ago, and pronounced it a valuable addition to any technical library. The present volume of 693 pages, addressed t o the research and technical developments applied t o the oil after it leaves t h e ground and prior t o its ulti mate use, is, if anything, a more valuable contribution. The volume is divided under t h e broad headings of a résumé of physi-
cal and chemical research, handling of the raw oil prior to distillation, distillation, cracking, hydrogénation with or without pressure, chemical treatment of the various raw materials, oxidation of oil and similar hydrocarbons, corrosion, lubricating oil, shale and tar oils, oil recovery, and analytical procedure. The various subjects are presented through a comprehensive international series of abstracts as they appeared in the Chemisches Zentralbhtt, with a further reference to t h e original publication from which trie abstract was made. In addition, there is a digest of international patents (including patents, otherwise difficult to obtain, from Japan, Russia, Hungary, Poland, Czechoslovakia, etc.) which should be extremely valuable to Americans interested i n petroleum patents. As a reference book dealing with international developments in petroleum technology during the period of 1928 t o 1932, Dr. Pfliicke has given us one of the most valuable and useful volumes which has come to the attention of the writer.

ΡΑΗΒβτοΡίΓΑΒΕΓ,ι,ΕΝ. GustaO Schuliz. 7th ed., revised and en larged b y Ludwig Lehman. Supplement to VOLUME I. 182 pages. Akadernische Verlagsgesellschaft m. b. H., Leipzig, C l , Germany, 1934. Price, paper, 30 marks; bound, 33.60 marks. THIS supplement to t h e seventh (1932) two-volume edition of the Schultz Farbstofïtabellen, in addition to amplifying material presented i n the main volumes, is packed full of information concerning new dyestuffs and textile assistants which have been produced in Germany and Switzerland and are not included in the main volumes. In construction and arrangement of contents, the supplement follows that of the main volumes; and convenient titles indicate clearly the connection. The amplifications of Volume I consist principally of references to literature and listings of dyeing and fastness properties. Most striking are t h e very complete tables of fastness properties of the azo dyestuffs derived from fast bases and naphthols. The sections concerning anthraquinone dyestuffs—mordant, acid, and vat—are also elaborated in considerable detail. The section corresponding to Volume II concerning dyestuffs of unknown composition, or unknown method of manufacture, occupies about naif the supplement. It covers 86 large pages and describes about four thousand different products. This section is of special interest and value because it includes principally, and gives considerable data concerning, products which in the main work or in the Colour Index are not listed at all or hardly more than mentioned. M a n y new series of products brought out in recent years t o meet new and diversified requirements of the dyeing and printing industries are covered in detail—for example, t h e Indigosols, t h e Ceiliton, the Anthralan, the Sirius, and the Ohlorantine dyes. The tables are incomplete to the extent that t h e trade names of dyestuffs manufactured in countries outside Germany and Switzerland are omitted; only such products as were produced by concerns in existence prior to the war and a few manufactured since are included. The section concerning textile assistants is exhaustive, describing principally products that have not previously been listed. Subject indexes, both for dyestuffs and for textile assistants, will be valuable i n t h e use of the tables. To the users, manufacturers, and sellers of dyestuffs and textile assistants, who wish t o have all possible available information on the subjects covered, these supplementary tables would seem to be well-nigh indispensable.
