[N. S. Vol. XLV. No. 1152 



Dysart, Boston, Mass.; Dr. Mary G. Haseman, 

 Jolins Hopkins University; Mr. J. B. Scarbor- 

 ough, North Carolina Agricultural and Mechan- 

 ical College; Mr. J. J. Tanzola, TJ. S. Naval 

 Academy. Ten applications for membership in the 

 society were received. 



In response to an invitation received from the 

 department of mathematics of the University of 

 Chicago, it was decided to hold the summer meet- 

 ing and colloquium of the society at that university 

 in 1919. Committees were appointed to arrange 

 for the summer meeting of 1917 and to publish the 

 Cambridge Colloquium Lectures, which will prob- 

 ably appear in the early summer. 



The total membership of the society is now 732, 

 including 75 life members; the annual published 

 list will be issued in January. The total attend- 

 ance of members at all meetings, including sec- 

 tional meetings, during the past year was 490 ; the 

 number of papers read was 205. The number of 

 members attending at least one meeting during the 

 year was 278. At the annual meeting 235 votes 

 were cast. The treasurer 's report shows a balance 

 of $10,198.38, including the life membership fund 

 of $6,039.87. Sales of the society's publications 

 during the year amounted to $1,434.28. The li- 

 brary now contains about 5,377 volumes, excluding 

 unbound dissertations. 



At the annual election, which closed on Thurs- 

 day morning, the following ofEioers and other 

 members of the council were chosen: 



President: L. E. Dickson. 



Vice-presidents : A. B. Coble, E. B. Wilson. 



Secretary: T. N. Cole. 



Treasurer : J. H. Tanner.

Members of the Council to serve until December 

 1919 : G. C. Evans, L. A. Howland, G. H. Ling, E. 

 L. Moore.
