 try and abroad has been continued, resulting in many additions both 

 in the form of new exchanges and the supplying of missing parts. 



READING ROOM. 



In the reading room the current foreign and domestic scientific 

 periodicals have been in constant use by the staff and the members 

 of the scientific bureaus of the governmental establishments in Wash- 

 ington, and there are now 294 titles on the shelves. Three thousand 

 five hundred and three publications from the reading and reference 

 rooms were circulated during the year. Of these 3,161 were single 

 numbers of periodicals, and 342 were bound volumes. 



THE AERONAUTICAL LIBRARY. 



One of the important collections of reference works at the In- 

 stitution is that relating to aeronautics, and is, in all probability, 

 the most complete series on this subject in the United States. The 

 collection had its origin with Secretary Langley when he was carry- 

 ing on his aeronautical experiments, at which time he was able to 

 secure many early works that can not now be purchased. 



One of the chief contributors during the year was Dr. Alexander 

 Graham Bell, a Eegent of the Institution, whose gift consists of his 

 working library on the subject, numbering 46 volumes, and another 

 series of 153 volumes of newspaper clippings relating to the im- 

 portant period when the Wright brothers were making their initial 

 flights. 



The additions to the collection during the year, including those 

 from Dr. Bell, were 256.
