Many of these papers will appear in the forthcoming 
volume of Memoirs, the printing of which is far advanced, 
and is expected to be completed before the commencement 
of the ensuing session. 
The system of admitting Sectional Associates has con- 
tinued to work satisfactorily, and the Council have there- 
fore resolved to recommend its renewal for another year. 
The Librarian reports that the Society continues to be in 
regular receipt of the usual Transactions, Memoirs, &c., 
issued by the various learned bodies with which the Society 
is in correspondence. The number of societies, &c., ex- 
changing their publications with this Society is now 256, 
74 of which are British and 182 foreign, or an increase of 5 
•British and 7 foreign upon the number of last year. 
Since the date of the last Report the attention of the 
Librarian has been chiefly given to the acquisition of volumes, 
parts, &c., which have been wanting for some time past, 
and it is gratifying to be able to state that unusually large 
and valuable donations of such desiderata have been added 
to the Library in the course of the past year. The Philo- 
sophical Transactions for 1845 and 1846, referred to in Vol. 
III. of Proceedings, p. 278, as having been lost, and many 
other Journals, &c., entered in the catalogue as wanting, 
have been replaced in this way.
