and at the same time as the officers of the 

 Chicago Section. 



At the first election of the jurors of the Willard 

 Gibbs Medal, to be held in 1911, four jurors shall 

 be elected to serve a term of one year, four to 

 serve a term of two years and four to serve a term 

 of three years. Of each four elected, two shall be 

 from the Chicago Section. 



6. At the call of the chairman of the Chicago 

 Section the jury shall begin its deliberation on 

 January 2 of each year. 



Each member of the jury shall be entitled to 

 place in nomination the names of two candidates. 

 The voting shall then be on these candidates. 



The four names receiving the highest number 

 of votes on the first ballot shall be retained, the 

 others rejected. 



If of the four names retained, none receives a 

 two-thirds vote on the second ballot, the two 

 receiving the fewest votes shall be dropped. If 

 on further balloting the committee finds it impos- 

 sible to make a selection by a two-thirds vote, it 

 will report to the section, which will proceed to 

 elect the recipient of the medal; but if any candi- 

 date receives a two-thirds vote of the committee, 

 his election shall be final and shall be so reported 

 to the section. 



7. It is desired that the paper or address, if 

 suitable, be published in one of the publications 

 of the American Chemical Society. 



8. The executive committee of the Chicago Sec- 

 tion shall have the power to decide any question 

 not specifically covered by these rules. 



9. The Chicago Section shall have the power to 

 change or amend these rules in the same manner 

 as the by-laws of the section. 



For the first year of the foundation, 1911, 

 by special amendment of the rules of the Sec- 

 tion a special jury of award was elected, con- 

 sisting of the following members : S. A. 

 Mather, chairman of the section and president 

 of the Thorkildsen-Mather Co.; W. Brady, 

 chief chemist of the Illinois Steel Co.; D. K. 

 French, secretary of the section and chemist 

 of the Dearborn Drug and Chemical Co.; W. 

 Hoskins, of Mariner and Hoskins; Professor 

 John H. Long, of the Northwestern Univer- 

 sity Medical School; A. Lowensteln, chief 

 chemist of Nelson Morris & Co. ; Professor H. 

 McCormick, of Armour Institute; Professor 

 H. N. McCoy, of the University of Chicago; 

 W. D. Richardson, chief chemist of Swift & 



Co.; Professor Alexander Smith, of the Uni- 

 versity of Chicago, and president of the 

 American Chemical Society, and Professor 

 Julius Stieglitz, of the University of Chi- 

 cago. By a unanimous vote the jury decided 

 to award the first medal to Professor Svante 

 Arrhenius for his fundamental work on the 

 theory of electrolytic dissociation. 



The medal was presented to Dr. Arrhenius 

 on the evening of May 12, after a banquet 

 which was attended by over 200 members and 

 guests of the section. The formal program of 

 the evening included the following addresses: 

 " International Bonds of Science," by Harry 

 Pratt Judson, president of the University oi 

 Chicago ; " Chemistry and Commerce," by 

 Mr. Wheeler, president of the Association of 

 Commerce of Chicago ; " The Willard Gibbs 

 Medal," by S. A. Mather, chairman of the 

 Chicago Section of the American Chemical 

 Society; "The Presentation of the Willard 

 Gibbs Medal to Dr. Arrhenius," by Alexander 

 Smith, president of the American Chemical 

 Society, and " The Willard Gibbs Address," by 

 the medallist, Svante Arrhenius, on " The 

 Theory of Electrolytic Dissociation." The 

 last address gave, in outline, the history of the 

 discovery of the theory of electrolytic disso- 

 ciation; it formed, on the one hand, an in- 

 tensely interesting record of the birth of a 

 great idea and theory, of its early difficulties 

 and its final triumph; and, on the other hand, 

 it presented a picture of the struggles, progress 

 and development of the genial discoverer of 

 the theory. 



The address will be published under the 

 auspices of the Chicago Section of the Amer- 

 ican Chemical Society.
