REPOET ON THE OPERATIONS OF EXCHANGES. 



Card catalogues. 



The information received from the foreign establishments in reply to 

 the circular relative to the preparation of a new list of foreign corre* 

 spondents served in the preparation of three card catalogues, of which, 

 one is to represent a list of scientific persons together with the partic- 

 ular branch of learning to which they are devoted. The second one is 

 to represent an account kept, with each establishment, of the Smith- 

 sonian publications on hand, as reported by the librarians, and shows 

 the successive sendings. As an illustration the card for the British 

 Museum, London, England, is given: 



No. 1819. 



The third card catalogue represents a general account of all trans- 

 actions of exchanges for any one establishment. For the sake of illus- 

 tration we will again select the card for the British Museum, London, 

 England (No. 1819, of the list of foreign correspondents) :
