PROCEEDINGS.

Upon request, 3 members have been transferred to the absent 
list, 3 have resigned, and 5 have been dropped for the non-pay¬ 
ment of dues. There has thus been a decrease of 11 in the 
number of active members from last year, but the addition of 10 
new members brings the active membership of the Society at 
the present time to 197. 
Besides the annual meeting and the one at which the address 
of the retiring President was delivered, the Society has held 15 
regular meetings, with an average attendance of 36 members 
and guests. At these meetings 38 communications were pre¬ 
sented by 32 members and 1 guest, and 44 members participated 
in the discussions. 
The General Committee has held 15 regular meetings, with an 
average attendance of 13. The least number at any meeting 
was 9 and the greatest 17.

ing the annual address of the President, besides a series of
