LIBRARIAN’S REPORT. 
In the last Annual Report it was stated that the increase 
of the library, during the twelve months then elapsed, had 
been considerably greater than during any previous year. It 
is gratifying now to have to report that the additions during 
the year 1858-9 have been still more numerous, consisting of 
not less than 299 volumes, 177 parts of volumes, and 80 
pamphlets. 
These additions are, as usual, chiefly derived from the 
exchange of our publications with those of scientific societies 
and institutions in this and foreign countries, and presents 
received from government departments and private individuals; 
all of which, included under the general title of Donations, 
amount to 271 volumes., 161 parts of volumes, and 80 
pamphlets. A specified list of these donations, will, as usual, 
be printed as an appendix to the Memoirs for the session. 
The publications which the librarian is authorised to pro- 
cure for the library by purchase, are 
The London, Edinburgh, and Dublin Philosophical 
Magazine, 
The Quarterly Journal of Pure and Applied Mathematics, 
The Cavendish Society’s Publications, 
The Palseontographical Society’s ditto. 
The Ray Society’s ditto, 
Les Annales de Chimie et de Physique, 
Poggendorfif’s Annalen der Physik und Chemie, 
Journal der reinen und angewandten Mathematik, 
Annalen der Chemie und Pharmacie, 
Annals of Natural History, and 
Journal de I’Ecole Poly technique. 
The set in the Library of the last-named Work to be 
completed up to the beginning of this year.
