EXCHANGES. 



The library receives continually a large number of exchanges 

 from scientific institutions, many as monographs and others in 

 periodical form. Where these are complete publications, or if 

 periodical., when the current numbers are received regularly, they

 completed they will be published in supplementary lists. 



CATALOGUES. 



The library has collected from time to time a large number 

 of catalogues of (1) leading American colleges and universities,

 under the regular library rules.

 A large native hard-wood case containing eight drawers 4 by 5 feet 

 in size and 2% inches deep, lately placed in the reading room, 

 provides an excellent place for caring for and consulting this class 

 of material. An effort will be made to secure other maps and 

 charts, especially those of local interest, and a list will be published 

 when the collection is more complete.

 Departments of the United States and of the Bureaus of the Phil- 

 ippine Government, as well as many foreign government reports, 

 are on file and are indexed by the card system according fo title

 desired to complete many of these sets before including them by
