REPORT OF NATIONAL MUSEUM, 1907. 37 



The collection of casts of classic sculpture, formerly in the graphic 

 arts court, was transferred to the hall now occupied by the National 

 Gallery of Art, 



Much progress was made in improving the installation and labeling 

 in the division of technology. The superb collection of arms deposited 

 by the United States Cartridge Company was moved to the cast hall 

 adjoining the general exhibit of firearms, where it properly belongs. 

 The Lilienthal flying machine was repaired and hung from the roof in 

 the east hall, and the Ilargrave machine is being prepared for exhibi- 

 tion in the same place. A large number of objects were sent from this 

 division to the Jamestown Exposition, causing many temporary gaps 

 in the exhibition halls. 



A few additions were made to the exhibition series in ceramics, the 

 graphic arts, musical instruments, and medicine, and more important 

 ones to the historical collection. 



Under existing conditions an extension of the biological exhibits 

 is scarcely practicable except in the case of small specimens, and the 

 efforts of the staff have been mainly directed toward keeping the 

 collections from deterioration and making such improvements as are 

 possible. The largest pieces added to the mammal series this year 

 were a grizzly bear and a skeleton of the beaked whale, Mesoplodon 

 grayi. A very large skeleton of another species of beaked whale. 

 Berardius bairdii, was laid out preparatory to mounting. About 40 

 small mammals, supplying deficiencies in the Nearctic, Neotropic, and 

 Palearctic series, were also installed. The new style of label holder 

 mentioned in last year's report was put into use in connection with 

 the exhibit of North American birds. The taxidermists have re- 

 mounted many of the valuable Old World birds and have cleaned 

 others, besides renovating the older groups of both mammals and 

 birds. A large amount of relabeling was done. 



About 3,000 specimens were added to the insect exhibit, and also 

 seven groups in Riker mounts, illustrating the life histories of insects. 

 It was found necessary to shut off another small section of the hall 

 containing the reptiles and fishes for the accommodation of additions 

 to the reserve collection of insects. This action involved the rear- 

 rangement of all the exhibition cases in the hall. 



The display series in systematic and applied geology was increased 

 by 17.") specimens and that of minerals by ( .>1 specimens. The most 

 conspicuous additions to the exhibit of vertebrate paleontology con- 

 sisted of a cast of Pareiasaurus baini, a restoration of Pteranodon, 

 and two remounts of the New Zealand Moa.
