 adopted. These have already been placed in 

 the hands of the permanent secretary. 



A request was received from the organiza-

The twenty-fourth annual meeting of the so- 

 ciety was held at Columbia University on Thurs- 

 day and Friday, December 27-28, 1917, extending 

 through two sessions on Thursday and a morning 

 session on Friday. The attendance included forty- 

 six members. Professors E. G. D. Eiehardson, of 

 Brown University, and J. W. Young, of Dartmouth 

 College, presided. The council reported the elec- 

 tion to membership in the society of Dr. J. "W. 

 Campbell, Wesley College, Winnipeg; Dr. Mary 

 F. Curtis, Western Reserve University; Mr. C. H. 

 Parsons, Columbia University; Mr. J. B. Eosen- 

 bach. University of New Mexico; Mr. H. M. Ter- 

 rill, Columbia University. Five applications for 

 membership were received. 



Committees were appointed to arrange for the 

 summer meeting of the society at Dartmouth Col- 

 lege in 1918 and for the summer meeting and col- 

 loquium at the University of Chicago in 1919. 



The total membership of the society is now 735, 

 including 77 life members. The total attendance at 

 all meetings, including sectional meetings, during 

 the past year was 338. The number of members at- 

 tending at least one meeting during the year was
