34 NINTH ANNUAL REPORT OP 



library is owing to the fact that the latter included donations from indi- 

 viduals and other sources in this country, which the former did not, and 

 that some separate sheets of maps were all bound together before being 

 placed in the library :

As was to be expected, a large proportion of receipts by exchanges 

 consisted of the publications of learned societies, many of which, in 

 addition to their current volumes, have sent their back series, either in 

 whole or part. This department of the library is rapidly becoming 

 more and more complete, and is believed even now to exceed that of 

 any other library in the country. The catalogue now in preparation of 

 the publications of societies and periodicals belcnging to the Institution 

 will furnish a ready means of indicating what are the desiderata of this 

 nature. 



In addition, however, to returns from societies, the receipts from 

 public libraries and universities of duplicates from their shelves have 

 been very numerous, and consisting, as they usually do, of important 

 scientific works, have proved highly acceptable. Owing to the con- 

 stant communication kept up with the principal men of science at home 

 and abroad, and the transmission to them of such publications of the 

 Smithsonian Institution as related to their specialities, very many valu- 

 able memoirs and works have been received in return from this source 



In the very great number of large donations received during the 

 year it has been found impossible to give a particular enumeration ot 

 them without encroaching too much in the space allotted to me. This 

 is, however, less necessary, as the catalogues now in preparation, and 

 shortly to be printed, will convey full information on the subject. 



The following tables contain a statement of the packages received 

 from the various sources specificed, for distribution in Europe as well 

 as those received from Europe for this country :
