may attend the winter meeting of the Chicago 

 Section and the meeting of Section A of the Amer- 

 ican Association, as well as the annual meeting. 

 At the latter meeting, which will be held in New 

 York, President Van Vleek will deliver his presi- 

 dential address. 



A committee was appointed to arrange for hold- 

 ing the summer meeting of 1915 at San Francisco. 

 It was decided to issue only the List of Oflicers and 

 Members next year, in place of the usual Annual 

 Eegister. 



The authorities of Brown University extended a 

 lavish hospitality to the society. The morning ses- 

 sion on Tuesday opened with an address of wel- 

 come by Chancellor A. B. Chace. Professor N. P. 

 Davis entertained the members and ladies at tea in 

 the John Carter Brown Library on Tuesday after- 

 noon, and at luncheon in Eookefeller Hall on 

 Wednesday. The university gave a dinner in honor 

 of the society at the University Club on Tuesday 

 evening, the occasion concluding with a cordial ad- 

 dress by President Paunee and an interesting ac- 

 count by Professor Carl Barus of the ' ' Historical 

 development of the modern theory of physics. ' ' A 

 vote of thanks was tendered to the university and 

 its officers for their generous hospitality. Wednes- 

 day afternoon was devoted to an excursion to 

 Newport.
