THE EDITOR'S BOOK TABLE 



HOW TO M.\KK AND USE A SMALL CIIE.MICAL LABORATORY 

 By Raymond Francis Yates. The Norman W. Henley Publishing Com- 

 pany, New York, 1920. (Paper, 102 pages, 5 by 7>i inches.) 

 THE .AUTHOR has successfully accomplished the task of preparing 

 a book for those who wisli to become acquainted with the great 

 fundamentals of chemistry. The author has not followed the 

 usual method of treatment but beghis at once by explaining in 

 non-technical language the nature and relations of molecules, 

 atoms and electrons. Since chemistry is discussed to-day in 

 terms of the Electron Theory, familiarity with its outstanding 

 features is essential at the beginning of its study. The second 

 part of the book is occupied by instructions to the amateur chem- 

 ist on the construction of a home laljoratory, while a third section 

 is devoted to experiments illustrating the broad aspects of chem- 

 ical science and to methods of constructing necessary apparatus.

INTERESTING LETTERS FROM OUR READERS 



ABOUT A NOVEL TOY BALL 

 To the Editor : 

 ^^F.AR SIR:— 



'■^ In The India Rubber World, July 1. 1919, you kindly 

 published an article showing my novelty ball. In consequence 

 of the world-wide publicity, I had letters from the Dutch traders 

 in Holland and many from the United States. I have made every 

 effort to get them made, but the factories are all "too busy." 



Will you be kind enough to tell mc if there are any books 

 for beginners in rubber work, or where could I get information 

 on the subject of making rubber balls; also the apparatus and 

 material for making in an experimental way, after which I shall 

 organize a company for making on a larger scale. It is surely 

 an improvement on what is recorded as the inost salable toy 

 ever placed on the market. 



Thanking you greatly for any infoimaticm you can give, I 

 remain.

HOT VULCANIZATION OF RUBBER 



F. Kirchoff in a recent article' claims ihat he discovered and 

 aiuiounced before Harries the physical-chemical principle of 

 vulcanization by heat, granting to Harries the credit of having 

 established by experiment the difference between primary and 

 after- vulcanization. 



The chemical interpretation of vulcanization has undergone 

 various modifications through the development of our knowl- 

 edge of the constitution of rubber, due to Harries and to the 

 investigations of Schmitz on the action of bromine or dcpolym- 

 erized rubber. 



The United States Postal Bulletin for Septe.mber 3, 1920, 

 announces that among the articles that may be imported into Ger- 

 many by parcel post without special authorization are balata, 

 raw or cleaned or the refuse of balata; gutta percha, raw or 

 cleaned, or the refuse of gutta percha ; and rubber, raw or cleaned 

 or the refuse of rubber.
