OK THK 



SMITHSONIAN INSTITUTION. 



Tn elTectino- the distribution of its first publications abroad, the Smith- 

 sonian Institution estabHshed relationships with certain foreign scientific 

 societies and libraries, by means of which it was enabled to materially 

 assist institutions and individuals of this country in the transmission of 

 their publications abroad, and also foreign societies and individuals in 

 distributing their publications in the United States. 



Tn recent years the Smithsonian Institution has been recognized by 

 the United States Government as in charge of its official Exchange 

 Bureau, through which the publications authorized by Congress are 

 exchanged for those of foreign govennnents ; and b}' a formal treaty 

 it acts as intermediar}' between the learned bodies and literary and 

 scientific societies of the contracting States for the reception and trans- 

 mission of their publications. 



Attention is invited to the fact that this is not a domestic, but an 

 international exchange service, and is used to facilitate such exchanges, 

 not within the United States, but between the Ignited vStates and foreign 

 countries only. 



The Smithsonian Institution will receive from any person or institu- 

 tion of learning in the United States a package addressed, under the 

 following rules, to any person or institution abroad, and will deliver it 

 to the addressee free of expense. Its agents and the exchange bureaus 

 abroad will likewise receive from associations of learning or individuals 

 in their respective countries such publications as may be delivered to 

 tliem under rules similar to those prescribed herein, and will forward 

 them to Washington, after which the Institution will undertake their 

 delivery, free of expense, to the respective addres.ses in the United 

 States. 



The rules established for the operation of the li^xchange Service 

 provide for the distribution of books, pamphlets, charts, and other 

 printed matter, sent as donations or exchanges, to any accessible point 

 abroad, and without expense t© the sender beyond that of the delivery 

 of the packages to the Smithsonian Institution in Washington, and 

 al.so without expense to the recipient. vSiniilar material sent from 

 abroad to this country is forwarded, prepaid l)y the sender, to the agents
