REPORTS OF THE PROGRESS OF APPLIED CHEMISTRY. ISSUED 

 by The Society of Chemical Industry. Volume 1, 1916. London. 

 Harrison & Sons. [8vo, 325 pages.] 



THIS volume presents the progress of applied chemistry, from 

 January, 1914, to June, 1916, reviewed in 15 sections, each 

 by a recognized authority. 



A section of 28 pages is devoted to India Rubber by H. P. 

 Stevens, who gives a very comprehensive outline of progress 

 under the following topics : 



Statistics of Production; Production of Raw Rubber; Non- 

 Caoutchouc Constituents of Rubber Latex; Effect of Details in 

 Preparation; Properties of Rubber; Properties of Vulcanized 

 Rubber ; Physical Tests of Vulcanized Rubber ; Quality and Uni- 

 formity of Rubber; Vulcanization; Accelerators; Synthetic Rub- 

 ber ; Analysis of Vulcanized Rubber. 



The section concludes with over a hundred references to ori- 

 ginal sources and is a valuable compilation for the rubber chemist 

 and student of rubber technology. 



EIGHTEENTH YEAR BOOK AND ANNUAL REPORTS OF THE 

 Rubber Association of America. Prepared by the Secretary. [8vo, 

 102 pages.] 



This annual publication, prepared and printed for the members 

 of the Association, contains a large amount of information of 

 value to them, and also to all engaged in the rubber industry. 



There is a full list of firm, associate and honorary members 

 of the Association, the list of officers and standing committees. 

 The several divisions are each represented in detail, with lists 

 of officers, committees and membership. These divisions repre- 

 sent the manufacturers of mechanicals, soles and heels, sundries, 

 hard rubber, also reclaimers, proofers, and those interested in 

 foreign trade. The constitution and by-laws, the report of the 

 seventeenth annual meeting, and the seventeenth annual banquet 

 are given in detail. Included also are the rules and regulations 

 governing transactions between buyers and sellers. There are 

 excellent double page half-tones of the banquet and the outing 

 of 1916. 



While much of this has been previously published, its collec- 

 tion and arrangement in permanent form makes the book one 

 valuable for reference in every rubber man's business office. 



CHEMICAL PATENTS AND ALLIED PATENT PROBLEMS. BY 



Edward Thoinas. John Byrne & Co., Washington, D. C. [8 vo, 58 



pages, interleaved for notes. Bound in buckram. Price. $2.50, de- 

 livered.] 



This volume, for which a genuine need has existed, represents 

 a complete rewriting of "Process Digest" by the same author, a 

 member of the Appellate Federal Bars of New York and Wash- 

 ington, all the cases having been reread from the point of view 

 of an attorney and expert witness, instead of that of a Patent 

 Office examiner. Chemists and their attorneys will find it a 

 clear and concise statement of the United States patent law. 

 The major part of the work discusses broad underlying prin- 

 ciples, while the remainder takes up points of practice and is 

 accompanied by a virtually complete "finding list" of the cases 

 on which the law of chemical patents is based, also including 

 other important cases intimately related in reasoning. Upwards 

 of 1,300 cases are cited under nearly 250 separate headings, with 

 brief individual comments. All citations are given in footnotes, 

 making the book interesting reading for the chemist and at the 

 same time enabling the attorney to refer readily to pertinent 

 cases. The references have been condensed by citing in general 

 only the appeal case, or the last of a series, if that rules on all 

 the points previously raised. Specific notes are given on the kind 

 of evidence needed in chemical and allied cases, also notes cover- 

 ing cases on damages, licenses, etc. 



THE FINANCIER RUBBER SHARE HANDBOOK. FOURTEENTH 

 Edition, May, 1917. The Financier & Bullionist, Limited, London, 

 Englai.d. [Cloth, 8vo, 877 pages. Price, 4 shillings, net.] 



As in the past, this convenient handbook contains a wealth 

 of details regarding the companies owning rubber plantations 

 in Ceylon, South India, Borneo, Java, Burma, Sumatra, Africa, 

 the Malay Peninsula and South America. It gives the author- 

 ized share capital of each of these companies, the amount issued, 

 the balance sheet, the list of directors, acreage and similar in- 

 formation well arranged and quickly available. An alphabetical 

 list of directors in all these companies is appended, including 

 a list of secretarial groups with London addresses. In his 

 preface, E. L. Killick, rubber expert of the "The Financier," 

 explodes the bogy of over-production, showing that enormous 

 expansion of the world's consumption has kept pace with in- 

 creased production. He further points out that as there has 

 been no extensive planting in the Middle East since the period 

 1910-12, and as the rate of increased production will rapidly 

 decline beginning with 1917, a continued increasing demand at 

 the past rate will find the world facing not a surplus, but an 

 actual shortage of rubber. 



BRAZIL TODAY AND TO-MORROW. BY L. E. ELLIOTT. F.R.G.S. 

 The Macmillan Co., New York City. [8vo, 338 pages, illustrated, cloth. 

 Price, $2.25.] 



Brazil continues to be a land of much moment to the rubber 

 trade, which will welcome this handsome, absorbing and com- 

 prehensive work by one who knows the country well. Its his- 

 tory and colonization are interestingly narrated and the present 

 and probable future status of its social conditions, transporta- 

 tion, industries, finance and commerce are clearly set forth. 

 The chapter on the world's horticultural and medicinal debt to 

 Brazil is little short of a revelation. 



A section of 28 pages presents intelligently the history, de- 

 velopment and details of the rubber industry of the Amazon as 

 contrasted with the plantation industry of Malaysia. Methods 

 of latex collection and coagulation, the system of labor and 

 financing, and the various kinds and grades of Brazilian rubber 

 are described. Measures necessary to put the industry on a 

 sounder basis, particularly more careful, cleanly and uniform 

 methods of coagulation, and more equitable and stable export 

 taxes, are outlined. The controversy is also referred to as to 

 the relative merits of plantations or further opening up of the 

 untapped reserves of the interior, estimated at 300 million trees, 

 many of them "black" Hevea yielding especially high quality 

 latex. The author doubts if the present average rubber pro- 

 duction of about 37,000 tons is likely to increase greatly for a 

 time at least, because of the scarcity of labor, the high cost of 

 living and the enormous expenditures necessary on roads, drain- 

 age and the like to open up virgin forests. 



THE MANUFACTURE OF RUBBER GOODS. BY ADOLF HEIL 

 and Dr. W. Esch, translated by Edward W. Lewis. A.C.G.I., F.C.S. 

 Charles Griffin & Co.. Limited, London, England. J. B. Lippincott 

 Co., Philadelphia, Pennsylvania. [Large 8vo, 236 pages, illustrated 

 cloth. Price, $4.] 



Among the authoritative technological handbooks for the use 

 of manufacturers, chemists and others engaged in the pro- 

 duction of rubber goods this work has since 1909 occupied a 

 prominent place. While the present reprint assumes a more 

 elementary character at this advanced stage of the industry, it 

 sets forth clearly and concisely those sound fundamentals which 

 must still be the basis of successful manufacture, and will prove 

 a useful addition to the library of every rubber man of the 

 younger generation. Five chapters are devoted to the raw ma- 

 terial, the vulcanization of rubber, the mixings, the manufacture 

 of soft rubber articles, and the manufacture of ebonite. The
