TWENTY-SIXTH ANNUAL REPORT. 



Your Committee has once more the satisfaction of presenting 

 a favourable Report. 



For some years past the number of new Members has been 

 insufficient to make up the usual losses by resignation or death, 

 and attention was drawn to this fact in the Annual Reports. 

 It is with considerable pleasui-e, therefore, that your Committee 

 is able to record the election of 47 Members in the twelve 

 months ujd to and including December, 1891, a larger total than 

 in any year since 1880, and they trust every effort will be made 

 to maintain this increase in the future. The resignatipns and 

 deaths number respectively 18 and seven, leaving our present 

 strength at 380. 



The attendances at the meetings have been unusually good, 

 and the papei^ and communications submitted at them quite 

 up to the average in number and quality, as the subjoined list
