ANNUAL CHEJIICAL DIRECTORY OF THE UNITED STATES. 

 Edited by B. F. Lovelace. Williams & Wilkins, Baltimore, Maryland. 

 [Octavo, cloth, 305 pages. Price $5, postpaid.] 



THIS, the first issue of the Annual Chemical Director}- of the 

 United States, inakes its appearance at a peculiarly opportune 

 time, when the importance of the chemical industry is real- 

 ized as never before, and when this industry in .America is mani- 

 festing a progressive spirit of accomplishment which it has never 

 known before. The scope of the volume is comprehensive, the 

 --.ontents accurate, and the arrangement such as to render the de- 

 sired address almost instantly available. It may well find a place 

 in the office of every business in which chemistry in any form 

 plays a part, for its twelve sections contain a great fund of helpful 

 information. To the purchasing agent of a rubber factory it is 

 invaluable. Whether it be desired to buy chemicals or laboratory 

 equipment, to employ a professional chemist, to consult labora- 

 tories, colleges, experiment stations, Federal or State officials, to 

 cooperate with chemical societies, or refer to cheipical publica- 

 tions, the necessary individual or firm name will be found under 

 the proper heading. All listings have been made gratis and 

 without regard to the advertising. Each section is alphabetically 

 arranged throughout; first by subheads, then by states and finally 

 by names. 



Chemists are classified as consulting, analytical, and chemical 

 engineers ; laboratories, as Federal and State, municipal, indus- 

 trial and professional. There are lists of American and foreign 

 colleges offering courses in chemistry, experiiuent stations, tech- 

 nical and scientific societies, chemical journals and important 

 books of 1916-1917. The survey of 1916 devotes some space to 

 the development of synthetic rubber in Germany, which can now 

 be produced at $1 per pound, estimated on the basis of the prices 

 of raw materials in August, 1914. Among the newer devices and 

 methods are mentioned a new double-bladed rubber masticator, 

 a new non-corrosive insulating material, and the use of Bakelite 

 in the making of pulleys and noiseless gears. 



LES CHOLESTEROLS AU POINT DE VUE SCIENTIFIQUE ET 

 Indiictriel. By Andre Dubosc, 49 Rue des Vinaigriers, Paris, France. 

 [Octavo, 103 pages, paper. Price. 26 francs.] 



This booklet consists of a collection of articles and experiments 

 concerning cholesterols, which originally appeared in our 

 esteemed French contemporary, "Le Caoutchouc & la Gutta- 

 percha.'' The author has treated, with liis usual regard for 

 detail and completeness in experiments, observations and tables, 

 such subjects as: Presence of cholesterols in greases and resins 

 of rubber ; proportion of cholesterol in the acetone extracts of 

 rubber ; analysis ; chemical, physical and physiological properties ; 

 physical and chemical structure, and ethers of cholesterols. 



RUBBER COMPANIES' ACCOUNTS. FOR PRODUCING AND NON- 

 Producing Companies. By R. S. Stewart, C. A., and F. C. Ebbels. 

 with a preface by Herbert Wright. A.R.C.S., F.L.S. Gee & Co.. 

 London, England. [8vo, 128 ]>ages. cloth. Price, 7s. Gd., postpaid.] 



Plantation accounting is a comprehensive and intricate matter 

 because of the great amount of detail required for monthly re- 

 ports from the manager on the estate to the directors of the com- 

 pany in England, America or elsewhere, and this is the first book 

 yet published on the subject. The authors have made an ex- 

 haustive study of the systems of leading companies and in the 

 light of their own extensive experience have combined the best 

 ideas into a seemingly adfequate and nearly ideal system which 

 will tend toward more sound financial methods in the manage- 

 ment both on estates and in company offices. An industry involv- 

 ing a capital of nearly $500,000,000 and 1,500,000 planted acres 

 certainly offers opportunities for standardized accounting, and 

 with that in view suggestions are solicited with the idea of ex- 

 tending the scope of the book at soine later date.

NEW RUBBER JOURNALS. 



XTOTWITHSTANDING the high cost of living and the high- 

 ^ ' er cost of paper, inks and printing throughout the world, 

 not to mention the threat of almost prohibitive American postal 

 rates proposed in the new war tariff bill, there seems to be no 

 lack of courage on the part of those eager to enlighten the rub- 

 ber trade, as shown by the following announcements. 

 ARCHIEF VOOR DE Rl'BBERCULTUUR IN NEDERLANDSCH-IXDIE. 



Under the above title (Archives of the Rubber Plantation In- 

 dustry in the Netherlands Indies), and in the form of a monthly 

 magazine 7J-^ by lO'A inches, will be published the reports of the 

 Java rubber experimental stations at Buitenzorg, Salatiga, Malang 

 and Djember, and the Sumatra station at Medan, which have 

 formerly appeared as various bulletins and jiamphlets. These 

 will be issued in Dutch as before, but accompanied by extensive 

 summaries and complete tabular matter in English. Book re- 

 views and abstracts from the rubber journals of the world will be 

 in Dutch only. This important innovation commends itself to 

 British and American readers because the committee of editors, 

 composed of the directors and officers of the experimental sta- 

 tions, consists of such well-known scientists as K. Gorter, J. G. 

 Fol, F. C. van Heurn, H. C. Pratt, W. Roepke, A. A. L. Rutgers, 

 A. J. Ultee, O. E. de Vries, Th. Wurth and H. J. Hellendoorn, 

 Buitenzord, Java, as Editor-Secretary. The features of the 

 first issue, dated February, 1917, consist of four articles by Dr. 

 O. de Vries, as follows : "Sugar as a Coagulant for Crepe Rub- 

 ber," "Influence of Rolling on Crepe Rubber,'' "The Influence 

 of the Rubber Content of Latex on the Inner Qualities of the 

 Rubber," and the "Influence of the .Amount of .Acetic .Acid on the 

 Inner Qualities of the Rubber." 



"THE RUBBER AGE." 



LTnder this comprehensive title a new American rubber trade 

 journal, edited by Herbert M. \\'illiams, is being published by 

 the Gardner, Moffat Co., Inc., New York City. It appears 

 semi-monthly at a subscription price of $1 a year, its announced 

 main purpose being "to assist in spreading such known technical 

 information as can be obtained from the laboratories and fac- 

 tories, as well as from the technical and engineering press," in the 

 belief "that a better and broader knowledge of the business and 

 commercial problems and market conditions, will be of service to 

 both the manufacturers and those to whom they sell, and will 

 bring about better understandings and more mutual cooper- 

 ation." The first issue, dated March 26, consists of 48 pages 

 about equally divided between reading matter and advertising, 

 and includes four feature articles, news of interest to the .Amer-
