ma ANNIVERSARY ADDRESS. 
‘The falling off in new members last year may partly 
accounted for by the fact that the entrance fee and ann 
subscription had been doubled by a resolution adopted towards — 
the close of the previous year; but that this was not the only 
reason, or even the chief reason, is made probable when we com- 
pare 1879 with 1878, the falling off between these two years 
as. the number on the roll is now about 460, this resolution may 
become operative before long. It is difficult, however, to 
state exactly the effective membership, as names are kept on the 
roll for one year after a subscription has been paid, unless it i 
definitely known that a member has retired. D
