for hospitalities extended to members in connec- 

 tion with their visits to this splendid institution, 

 and for the exceptional covirtesies tendered in con- 

 nection with the Shaw banquet. 



The association is under obligations to the 

 officers of the Louisiana Purchase Exposition for 

 the luncheon and reception at the grounds of the 

 exposition, and to the chiefs of departments un- 

 der whose guidance the members were privileged 

 to witness the progress already made toward the 

 completion of this monumental work. 



The association must further acknowledge its 

 indebtedness to the press, to the St. Louis Transit 

 Company, to the president of the Board of Public 

 Improvements and to all other organizations, cor- 

 porations and individuals who have extended so 

 many privileges to members individually and in 

 groups in connection with visiting the great in- 

 dustries and points of interest in St. Louis and 

 vicinity. 



The association is under deep obligations to the 

 Mercantile Club, to the University Club, and 

 finally and in especial measure, to the Wednesday 

 Club for the thoughtful hospitalities extended to 

 the ladies registered at the meeting. 



It was unanimously voted to extend the 

 thanks of the association to Professor 

 Butherford for his lecture on radium and 

 radio-activity.

THE ELEMENTS: VERIFIED AND 

 UNVERIFIED.* 



It is the sad duty of the retiring chair- 

 man of this section to chronicle the death of 

 two members. One of them, James Francis 

 Magee, B.S., University of Pennsylvania, 

 1887, devoted his life chiefly to commercial 

 pursuits, in which he was most successful. 

 He joined the association at the fifty-first 

 meeting, being one of the youngest mem- 

 bers. The other was H. Carrington Bolton, 

 Cohnnbia, 1862 (Ph.D. Gottingen, 1865), 

 who, with the exception of four ( Gibbs, 

 Boye, Brush and Hilgard), was the senior ,. 

 of the section, having joined at the seven- ft 

 teenth meeting. I beg permission to quote * 

 from an article of his in the American 

 Chemist, 1876, the year following his ele- 

 vation to fellowship in the association, as 

 it exemplified in telling words one of the 

 great aims in his life, Avith the fruitful 

 accomplishment of which you are familiar : 



"So rapid are the strides made by sci- 

 ence in this progressive age and so bound- 

 less is its range, that those who view its 

 career from without find great difficulty in 

 following its diverse and intricate path- 

 ways, while those who have secured a foot-
