of Georgia, from individual members; and the magnificent plates 
to Audubon’s Ornithology, and the invaluable works of Olivier and 
Voet, presented by subscription. The former of these donations, 
are tco well known to require a single remark; of the latter works, 
the curator of Entomology observes in his report upon Mr. Hentz’s 
collection, of which they made a part, ‘it is hardly necessary to ad- 
vert to the works of Olivier and Voet, which came with the insects. 
They are adorned with numerous plates, engraved by the best artists 
of the day and beautifully colored. The work of Olivier is in 10 vol- 
umes quarto, splendidly bound in calf and gilt; that of Voet in 4 
vols. quarto, is in fancy boards, but the plates are even superior to 
those of Olivier’s work. There is in the College library an imper- 
fect and incomplete copy of Olivier’s work, with uncolored plates, 
and in the library of the Academy of Natural Sciences of Philadel- 
phia both of these works are to be found. These are, as far as I 
know, the only ones in the country—they are rarely to be obtained in 
Europe, and then only at a high price and some risk to the importer.”
