publications of importance in completing the sets and series in the 

 library. Dr. C. W. Richmond has also continued to give to the 

 Museum many rare scientific works not to be found elsewhere in the 

 city. The plan adopted by the Regional Bureau of the International 

 Catalogue of Scientific Literature, of sending to authors lists of their 

 scientific writings that have been entered in the Catalogue and re- 

 questing any that have not been cited, has proven of special benefit 

 to the Museum through the acquisition of many separates from peri- 

 odicals, journals, etc. 



The library now contains 30,307 volumes, 47,042 unbound papers, 

 and 108 manuscripts. The additions during the year consisted of 

 2,581 books, 3,567 pamphlets, and 111 parts of volumes. There were 

 catalogued 1,301 books, 3,567 pamphlets, and 18,215 parts of period- 

 icals. The number of cards added to the reference catalogue was 

 6,330. (Japs in 550 sets of publications were completely or partially 

 filled, and 1,020 books were bound. 



The number of books, periodicals, and pamphlets borrowed from 

 the general library amounted to 34,859, including 9,397 assigned to 

 the sectional libraries, of which there are 29. 



PHOTOGRAPHY. 



The photographic laboratory, which is one of the best equipped for 

 its purpose in existence, has for its object the preparation of illus- 

 trations for the publications of the Museum, for the manuscript 

 records of important collections, and for the exhibition halls, and of 

 copies of plans relating to details of construction in connection with 

 the buildings, furniture, etc. 



The number of negatives made during the year was about 1,600; of 

 silver, velox, bromide and platinum prints, about 3,600; of blueprints, 

 2,177; and of bromide enlargements, 229. Most of the enlargements 

 and some of the other work enumerated were prepared especially for 

 the exhibit of the Museum at the Jamestown Ter- Centennial Ex- 

 position, for which there was also assembled by Mr. T. W. Smillie, 

 chief photographer, a unique collection illustrative of the history of 

 photography from 1824 to the present time.
