Of the above, 57 have been received from Authors, 34 from Editors, 90 from 
Societies, Corporations, &c., 834 from Dr. T.B. Wilson, 1767 from Edward 
Wilson, Esq., 98 from other Members and Correspondents, and from miscella- 
neous sources, and 6 from the U. 8. Government; making a total of 2886 addi- 
tions to the Library in 1852. 
From our fellow-member, Mr. Elias Durand, we have also received 109 auto- 
graphs of distinguished scientific and literary men. 
The excess in the increase of volumes this year over that of the last is 631. 
In 1851, the Library was increased 1075 volumes; in 1850, 1719 volumes ; in 
1849, 789 volumes; in 1848, 652 volumes; and in 1847, 630 volumes; making a 
total increase in six years of 6571. Many periodicals, also, in course of publi- 
tion during these years, and recorded as such in our lists of donations to the 
Library, have since been bound into volumes, the number of which may be esti- 
mated at about 700; and added to the above, give a total of nearly 7300 volumes 
contributed to the Society’s Library in that short period. 
In the Report submitted to the Academy in December 1850, the number of 
volumes in the Library at that time, as ascertained by actual enumeration, was 
12,057. If to these be added those since received, with the proportion of
