*Argles, Charles. Chemicals and industrial materials with their commercial uses. [Birmingham, England, 1921., 244 p. 8°. 10s. 6d. Desk (118)

The chemical librarian is often asked concerning a certain chemical: "What are its uses?" Mr. Argles briefly supplies this information. In addition to the alphabetical lists of chemicals and materials there are separate lists comprising materials used in specific industries, as: agriculture, baking and confectionery, paper making, leather making, etc.

"Such a book as this has been frequently contemplated, but, to the best of our knowledge, Mr. Argles is the first to have put the idea into execution, and, on the whole, has produced a volume which will be distinctly useful to manufacturers and merchants who from time to time want to know in what branches of industry their products are utilized." — Chemical trade journal, Sept. 24, 1921.

"It has been sought in this work to interpret (1) the commercial and industrial aspects of the trade; (2) the nature, structure and the qualities of the yarns employed; (3) the weaving principles involved; (4) the design and colour schemes elaborated; and (5) the systems of fabric build and manufacture practised... Technical and working data are supplied bearing on the manufacture of (a) each standard class of dress fabric...and (b) relative to the manufacture of the many varieties of 'fancy' and mixedyarn fabrics."

Space limits preclude full justice to this fascinating work. In a direct, clear style, supplemented by excellent microphotographs, are set forth many surprising facts. The subject is introduced by chapters on microscopic methods and on surface tension in liquids and solids. We are then told how aggregation takes place and how polishing is dependent upon metal flow. There are chapters on crystalline and vitreous states of ductile_metals, rocks and ice; on molecular pulsation; on Faraday's studies with thin metal leaves; and on the phosphorescence of crystals affected by the change from the crystalline to the vitreous state.

"This remarkable work, which summarizes and supplements twenty years of research by Sir George Beilby, will not only appeal to the student and laboratory worker, but should charm and delight every artificer or person who constructs with solids; as, if opened anywhere, the book will give some hint or sentiment of a new or unexpected property incidental to the solid state, all being told in so pleasant and intelligible fashion that an ordinary village carpenter or an average blacksmith's apprentice may understand...the basic idea being always expressed concisely, clearly and unmistakably. The reader will soon find side issues of interest, a state of things giving admirable incentive to further study... A book of the century...which in respect to its mass of notable facts and brilliant deductions, should, in time, take rank with Darwin's Voyage of the Beagle, or Faraday's Lectures on a candle."

It is a book which will be of value not only to the student and manufacturer, but also to the chemist, especially the consultant, as he will be able to get a clear insight into the applied science of leather manufacture, and where more detailed information is required, ref. erences both technical and scientific are very comprehensive."

Besides the historical introduction and the usual descriptions of the various parts, there are chapters on producer gas, welding repairs, x-ray examination of materials, tire repairing by vulcanization, body work, motor legislation, and roads. 299 illustrations.

"As a whole, the information is not very deeply technical and will be more useful to those who wish to have a general knowledge of the motor car than to the really technical man who wants information of details of design... One of the most useful chapters is the one on American electrical apparatus. There is no doubt that the Americans have been very successful in the application of electricity to the motor car, both for lighting and engine starting." - Engineering, Oct. 14, 1921.

A comprehensive elementary laboratory guide to a wide range of subjects of interest to physicians, physiologists, pathologists, botanists, agriculturists, and commercial chemists. M. Bertrand credits the translator with a number of additions and improvements.

"While the title...implies its dedication to biological chemistry, the authors have been by no means restricted to this field. Chapters are devoted to the isolation and detection of the alkaloids, to the elements of microbiology, glucosides, essential oils, and the description of the terpenes. Further, scattered throughout the text are a large number of directions for qualitative and quantitative procedures which, strictly speaking, fall far outside the range of biological chemistry.. In conclusion it may be said that the translation is apparently an excellent one, being clear and precise." Allan W. Rowe in Journal of the American Chemical Society, Aug., 1921.

Mr. Bolton was the winner of the Eugene Higgins Prize for the best essay on this subject. This essay has now been expanded to twelve or thirteen times its original length. Mathematical symbols have also been introduced with considerable freedom, although the formulae and equations are comparatively simple and amply explained. In the perspective of the work metaphysical notions do not loom large. A clear exposition that is "strictly relevant to the main issue, and side-tracking the non-essential."

"The authors have drawn, not only from their own experience but from the best sources available, information as to the most approved methods of working the various kinds of steel now in commercial use. While not intended as a treatise on steel making or metallurgy in any sense, it has seemed best to include a little information as to the making of different steels." - - Preface.

Covers steel making, composition and properties of steels, alloys and their effect upon steel, application of Liberty engine materials to the automotive industry, the forging of steel, annealing, case-hardening or surface-carburizing, heat treatment of steel, hardening carbon steel for tools, high-speed steel, furnaces, and pyrometry and pyrometers.

Covers evolution, types, details of construction, capacities and ratings, fuels and firing, draft, economizers, feed water, management, and selection.

"The drawings are line blocks, without any of those illegible useless abominations known as publishers' blocks or catalogue cuts. They are really elucidative of the text, and the whole work is the clearest exposition of steam boilers that we have seen. To the engineer it forms a necessity, and not merely a want." - Practical engineer, Oct. 31, 1921.

Author is Assistant Professor of Chemistry in the College of the City of New York.

"A laboratory course in the rarer elements is often objected to on the ground that the materials required are expensive. To meet this difficulty, it was neces sary first, to provide that in each test a very small though definite quantity of metal be used; second, to carry out numerous experiments to determine the conditions under which conclusively visible results could be obtained when using small amounts of the metal."

In this work, which is not deeply technical, a knowledge of direct currents as given in v. 1 (see New technical books, Oct.-Dec., 1920, v. 5, no. 4) is presupposed; but no knowledge of alternating currents is required. Fundamental laws are explained, as well as their applications to alternating current measurements, polyphase currents, alternating current machinery, and power transmission. Also includes a chapter on illumination and photometry. Mathematical developments are occasionally introduced as supplementary to the descriptive matter and there are numerous problems and methods of making laboratory tests.
