114 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1924 



The gift of Dr. F. W. Clarke of 170 pamphlets, in continuation 

 of his collection of papers on the atomic weights, brought the total 

 number of publications accessioned up to 477. 



There were 51 additions to the aeronautical collection. The 

 growth of this collection during the past decade has been due almost 

 entirely to the personal efforts of Mr. Paul Brockett, who has secured 

 for it many rare and valuable works, the acquisition of which would 

 otherwise have entailed great expense. 



The cataloguing of the European Historical Series of the Watts 

 de Peyster collection is approaching completion. 



UNITED STATES NATIONAL MUSEUM 



The library of the National Museum now contains 63,691 volumes 

 and 101,057 pamphlets, making a total of 164,748 publications. Of 

 these 1,521 volumes and 2,667 pamphlets represent the increase of 

 the year; 14,528 parts of periodicals were entered. Owing to lack 

 of funds, only 163 books were bound. 



The number of loans reached a total of 10,577. Many more vol- 

 umes were consulted without being taken out. There were borrowed 

 1,929 books from the Library of Congress and 130 from other 

 libraries. 



When it is realized that 6,139 of the library's loans were made to 

 the sectional libraries, the importance of the latter will become 

 readily apparent. The sectional libraries maintained are as follows :

 suggestions for the increase of its collections in the fields listed 

 above. Among the donors for the present year should be men- 

 tioned Messrs. Paul Bartsch, R. S. Bassler, J. E. Benedict, A. G.
