During the past year the By-laws have been altered as follows : 
Art. III. of Chapter IIJ., strike out the word jifty and insert one hundred, 
making the clause to read as follows: 
Art. III. But any member who shall pay into the hands of the Treasurer the 
sum of one hundred dollars shall be exempt from all future semi-annual contribu- 
tions. 
Art. I. of Chapter VIII, altered to read as follows: 
Any Specimen belonging to the Academy and not presented under restrictions, 
may be loaned to members or correspondents for purposes of scientific investiga- 
tion by the consent of three-fourths of the Curators, and for a period not exceed- 
ing three months; any person to whom specimens may be loaned shall first 
deposit with the Curators a sum, not less than Fifty Dollars, in cash, which they 
may deem necessary to ensure the safe return of the specimen, and he shall be 
subject to a fine equal in amount to one-third of the security given, for each 
month that the specimen may be retained beyond the time specified for its re- 
turn. The specimen loaned, together with the date at which itsreturn may be 
due, shall be reported to the Academy by the Curators at the meetings for Busi- 
ness in March, June, September and December. 
All of which is respectfully submitted by 
B. Howarp Ranp, 
Recording Secretary.

Of the whole number, we have received from Authors 68, from Editors 39; 
from Societies and Corporations 170; from Dr. Wilson 266; from Edward 
Wilson, Esq. 407; from other Members, Correspondents, &c. 56; and from the 
United States Government 5. Total 1011. 
The number of volumes now in the Library may be estimated at nearly 16,000, 
including tracts bound in volumes, or arranged for binding. Of these about 5000 
are on subjects of Natural Science, nearly 3000 volumes of Transactions, and about 
1500 volumes of Voyages and Travels, and Anatomy and Physiology. 
An opportunity for a correct enumeration will be afforded, it is hoped, during 
the coming year, when the contemplated enlargement of the accommodations for 
the Library will be completed. 
The increase in the number of additions this year from Foreign Societies is very 
gratifying, most of them having been obtained by exchange of publications.
