PHOTOGRAPHY. 
In the photographic laboratory, which is well equipped for the pur- 
pose, there were made 1,681 negatives, 3,820 silver prints, 465 platinum 
prints, 514 velox prints, 1,903 cyanotypes, and 56 bromide prints. 
These photographs were almost exclusively of objects in the collec- 
tions for use in illustrating scientific reports or in perfecting the 
records and catalogs. Some, however, related to structural details of 
the buildings, to articles of furniture, and to other general museum 
subjects. The chief photographer, Mr. T. W. Smillie, also continued, 
as in previous years, to conduct the examinations in photography for 
the U. S. Civil Service Commission.

Institution and National Museum, which were represented on the

were mainly selections from the exhibit made at the Louisiana Purchase 
Exposition, but with only about one-third the space the display was

photographic enlargements of geological subjects and of animals at 
the National Zoological. Park; framed plates from Audubon’s great 
work on birds;:a nearly complete skeleton of the extinct Dodo; a 
facsimile of a painting of the living Dodo from a copy in the British
