﻿ANNUAL REPORT. 



V 



Library. 



Great additions have been made to the Library during the year, 

 arising from presents to the Society, from purchases made by order 

 of the Council, and especially from the Transactions and Journals of 

 Foreign Societies received in exchange for the Society's Publica- 

 tions. The plan of exchanging Publications with Societies abroad 

 has produced such excellent results, that the Committee hope it will 

 be continued. A list of the principal additions is added to the Re- 

 port. 



Owing to the large additions, it has been necessary to re-arrange 

 and re-label the Books, which is at present in progress.
