PROCEEDINGS. 
545 
have been by members, and 3 by guests; 54 members and 
guests have taken part in the proceedings. 
The Society is indebted to the courtesy of the authorities of 
the Columbian University for the use of their large lecture- 
room on December 7, when the President presented his annual 
address, and for the use of a smaller room in which the meet¬ 
ings of the Mathematical Section have been held. All other 
meetings of the Society have been held in the hall of the 
Cosmos Club, the Society paying a small amount to defray a 
portion of the expense of lighting and heating. 
In the Mathematical Section 7 meetings have been held, with 
an average attendance of 14; 14 communications have been 
presented, 22 members and guests have participated in the dis¬ 
cussions, and an aggregate of 23 members and guests in the 
scientific proceedings of the section. 
The General Committee has held 15 regular meetings and 1 
special meeting; the average attendance has been 13, the least 
number at any meeting being 8, and the greatest, 17. 
The new rules for the publication of the Bulletin, which were 
adopted December 22, 1888, were first applied to the address of 
the retiring President for that year, Mr. Garrick Mallery. 
The paper was printed in February, 1889, and was at once dis¬ 
tributed to the members of the Society. Seven papers have 
now been published, including the address of the President for 
1889, and we believe that the new method of publication has 
added materially to the value of our Bulletin. 
■ Very respectfully, 
J. S. Diller, 
W. C. Winlock, 
Secretaries. 
The annual report of the Treasurer was read, accepted, and 
referred to an Auditing Committee, consisting of C. D. Walcott, 
W. A. De Caindry, and W. Eimbeck.
