REPORT ON THE OPERATIONS OF EXCHANGES. 



Ill 



Among the packages enumerated in the above were 3,030 addressed 

 to the Smithsonian Institution, and these contained 1,507 volumes, 10,393 

 parts and pamphlets, and 143 maps and engravings. Assuming the 

 same ratio for the remaining parcels, it will be seen that about 40,000 

 books, pamphlets, &c., have been distributed within the United States 

 during the past year. 



The history and condition of domestic exchanges, from their com- 

 mencement to the present time, are exhibited in the following table :
