AWARDS BY THE FRANKLIN INSTITUTE 



The Franklin Institute, acting through its 

 Committee on Science and the Arts, has re- 

 cently awarded medals to the authors of espe- 

 cially meritorious papers that appeared in the 

 Institute's Journal during the year 1916. In 

 making these awards, the committee adopted 

 the following resolutions: 



That the Howard N. Potts Medal be awarded to 

 Professor Ulric Dahlgren for his paper entitled, 

 "The Production of Light by Animals," appear- 

 ing in various issues of the 1915 and 1916 Jour- 

 nal of The Franklin Institute, forming an original 

 and comprehensive treatise of an extremely in- 

 teresting and important subject. 



That the Edward Longstreth Medal of Merit be 

 awarded to Mr. George A. Eankin for his paper en- 

 titled "Portland Cement," appearing in the June, 

 1916, issue of the Journal of The Franklin Insti- 

 tute, a highly important contribution to the theory 

 of cement chemistry. 



That Edward Longstreth Medals of Merit be 

 awarded to Professor A. E. Kennelly, Messrs. F. H. 

 Achard and A. S. Dana, for their joint paper en- 

 titled "Experimental Eesearches on the Skin Ef- 

 fect in Steel Rails," appearing in the August, 1916, 

 issue of the Journal of The Franklin Institute, con- 

 taining new and valuable experimental data, here- 

 tofore unavailable to the designers of track return 

 systems. 



That the Edward Longstreth Medal of Merit be 

 awarded to Mr. John D. Ball for his paper entitled, 

 "Investigation of Magnetic Laws for Steel and 

 Other Materials, ' ' appearing in the April, 1916, 

 issue of the Journal of The Franklin Institute, con- 

 taining new and valuable information relating to 

 the magnetic properties of materials used in the 

 magnetic circuits of electrical machinery. 



That the Edward Longstreth Medal of Merit be 

 awarded to Professor Dayton C. Miller, for his 

 paper entitled "A 32-Element Harmonic Synthe- 

 sizer," appearing in the January, 1916, issue, and 

 his paper entitled, ' ' The Henrici Harmonic An- 

 alyzer and Devices for extending and facilitating 

 its Use," appearing in the September, 1916, issue 

 of the Journal of The Franklin Institute, a compre- 

 hensive and lucid discussion of harmonic synthesis 

 and analysis, together with descriptions of per- 

 fected apparatus for synthesizing and analyzing 

 functions of one variable expressible by Fourier 's 

 equation. 



THE AMERICAN CERAMIC SOCIETY AND 

 MILITARY PREPAREDNESS 



The American Ceramic Society at its an- 

 nual meeting held in New York, March 5 

 to 8, authorized the formation of a Committee 

 on Military and Economic Preparedness, 

 which has now been organized and has begun 

 its activity. The committee has offered its 

 services to the National Defense Council and 

 the National Research Council. 



This society devotes itself to the study of 

 the chemistry and engineering of the silicate 

 industries, embracing the manufacture of clay 

 products, glass, cements and other cognate 

 lines like the manufacture of abrasive wheels, 

 the enameling of metals, etc. It does not deal 

 with the artistic or historical phases as the 

 name alone might lead one to infer. In its 

 membership it has many of the leading spe- 

 cialists in the country, all of whom are eager 

 to serve the country in this crisis. A census 

 has been taken of the membership with a view 

 to showing the number of firms and specialists 

 available in each subdivision of the field, 

 which have military significance. 



Up to the present time eight divisions have 

 been created which embrace in their member- 

 ship leading manufacturers and technical 

 men. The personnel of the committee is as 

 follows : 



Edward Orton, Jr., chairman, Ohio State Univer- 

 sity, Columbus, O. 

 A. V. Bleininger, vice-chairman. Bureau of 

 Standards, Pittsburgh, Pa. 

 Divisions and chairmen of sub-committees: 



Abrasives: E. C. Purdy, Norton Company, Wor- 

 cester, Mass. 

 Chemical Stone Ware: E. H. Minton, Metuchen,

 Enameled Iron and Steel: E. D. Landrum, Har- 



shaw. Fuller & Goodwin Co., Cleveland, O. 

 Glass for Optical Purposes: C. H. Kerr, Ameri- 

 can Optical Co., Southbridge, Mass. 

 Hydraulic Cements: P. H. Bates, Bureau of 



Standards, Pittsburgh, Pa. 

 Porcelain, for Electrical Purposes, Spark Plugs, 

 etc.: L. E. Barringer, General Electric Co., 

 Schenectady, N. Y. 

 Eaw Materials for the Ceramic Industries: A. S.
