ANNUAL REPORT, 1899-1900. 



The Council have to report that the past year has been one of great activity in the 

 society's work. 



Fifteen new members have joined the Society since the last annual meeting, but 

 the Council have also to report four resignations and two deaths, hence the total 

 number of members is now 263 as against 254 last year. Of these ten are honorary 

 and the rest ordinary members. The list of honorary members remains unchanged. 

 It is with deep regret that the Council have to report the deaths of two valued 

 members of the Society : Sir Rawson William Rawson and Mr. Edgar Leopold 

 Layard, accounts of whose lives will be found in the pages of the Journal.
