There have been received from the Librarian, during the year, 119 

 copies of the several numbers of the Transactions for sale or exchange ; 

 and of these, 105 copies have been disposed of in the way of exchange, and 

 8 copies by sale, leaving 6 copies in hand. 



There have been added to the Foreign List of exchanges 14 societies 

 and individuals, and to the Home List 10, making a total of 24. 



The whole number of names on the Foreign List, at the present time, is 

 245, distributed as follows : Sweden and Norway, 4; Russia, 9; Denmark, 

 3; Holland, 11; Germany, loi ; Switzerland, 11; Belgium, 9; France, 

 26; Italy, 18; Spain, 3; Portugal, 2 ; South America, 8 ; Mexico, 5 ; East 

 Indies, 6; Great Britain and Iieland, 29. 



The whole number on the Home List is no (U. States, loi ; British 

 Provinces, 9). 



The total number of exchanges is, then, 355, to which our Transactions 

 are regularly sent as issued, and from the greater part of which their pub- 

 lications are received in return. 



A full list of the publications that have been received through the Cor- 

 responding Secretary, since the printing of the last number of the Trans- 

 actions, will appear in No. i of vol. iv., shortly to be issued. 



Our foreign exchanges are conducted mainly through the Smithsonian 

 Institution and its Agencies (as heretofore) at a moderate expense to the 

 Academy. By this means, our operations are greatly facilitated : other- 

 wise, the expense would probably be greater than the Academy could sus- 

 tain from its present resources. 



The whole number of Corresponding Members now upon the list 

 (elected since the foundation in 1856) is 174. The number of those who 

 are deceased has not been accurately ascertained. One only has been 

 added to the list during the past year. 



The publication of No. i of vol. iv. of the Transactions (delayed for 

 some months for the completion of papers deemed important to be inclu- 

 ded) will not need to be much longer postponed. It will bring the report 

 of our proceedings down to the end of the year 1879. 



The account of the Corresponding Secretary for the year 1879 ^^ here- 

 with submitted in detail, showing a total of receipts of $35-75 and expen- 

 ditures $31.11, leaving a balance in hand of $4.64.
