CEEMISTBY AT THE JUBILEE MEETING OF 

 THE AMERICAN ASSOCIATION. 



The union meeting of Section C of the 

 American Association for the Advancement 

 of Science and the American Chemical So- 

 ciety in Boston during the last week in 

 August possibly approximated the desires 

 expressed two years ago by the promoters 

 of the joint session. The Jubilee meeting 

 of the American Association dragged many 

 who have not habitually attended the ses- 

 sions from their seclusion. Those who did 

 come, either for the first time or only after 

 a lapse of years, observed an inspiring sight 

 in the progress in the Association, and we 

 are constrained to believe that Section C 

 contributed its share to the success of the 

 meeting. 



Almost three hundred chemists attended 

 the joint sessions. "While Section C has 

 been largely composed of members of the 

 American Chemical Society, many more 

 joined that Society, and numerous applica- 

 tions, in turn, were sent to the American 

 Association. We are inclined to the opinion 

 that did other of the afiBliated societies but 

 unite with the various sections in joint ses- 

 sions only mutual good and benefit would 

 result, as has been the case with Section C 

 and the American Chemical Society. 



Some 94 papers were presented before 

 Section C and the American Chemical So- 

 ciety ; 51 in full, 31 by abstract and 12 

 by title, representing the various branches
