nection it is important to note tliat in the 

 summary to this series of papers Dr. Noyes 

 expresses his conviction that " the ionization 

 of salts, strong acids and strong bases is a 

 phenomenon primarily determined not by spe- 

 cific chemical affinities, but by electrical 

 forces arising from the charges on the ions, 

 that it is not affected, excepting in a second- 

 ary degree by chemical mass action, but is 

 regulated by certain general, comparatively 

 simple laws, fairly well established empiric- 

 ally, but of unknown theoretical significance, 

 and that, therefore, it is a phenomenon quite 

 distinct in almost all aspects from the phe- 

 nomenon of dissociation ordinarily exhibited 

 by chemical substances, including that of the 

 ionization of weak acids and bases." 



It is scarcely necessary to emphasize the im- 

 portance of such a study of aqueous solutions 

 as Professor Noyes has inaugurated, for, in 

 addition to the direct physical and chemical 

 significance of the knowledge thus to be 

 gained, every one will recognize the im- 

 portance of such investigations in their bear- 

 ing on certain phases of chemical technology 

 and chemical geology. E. 0. Franklin

THE SOCIETY OF CHEMICAL INDUSTRY 



In place of the regular meeting of the So- 

 ciety of Chemical Industry on Janu&ry 24, a 

 joint meeting of the Society of Chemical 

 Industry, the American Chemical Society, 

 the American Electro-Chemical Society, the 

 Chemists' Club of New York City and the 

 Verein Deutscher Chemiker was held for the 

 presentation of the Perkin Medal to Mr. J. B. 

 F. Herreshoff. Mr. George C. Stone was in 

 the chair. 



After a few introductory remarks by the 

 chairman, in which he emphasized the im- 

 portance of stimulating chemical research by 

 proper recognition, and bringing to the atten- 

 tion of the audience the life-work of Sir Per- 

 kin, who not only discovered a new product, 

 but worked out its manufacture, developed
