REPORT OF NATIONAL MUSEUM, 1910. 27 
the new building were occupied early in the year and progress has 
been made in classifying and properly caring for the large body of 
duplicate casts and molds and in installing the fittings. The labora- 
tory is in charge of Mr. Henry W. Hendley, assisted by Mr. Joseph 
Palmer, modeler. Although the work is much diversified, the services 
of Mr. Hendley being frequently called for by other departments, 
much of the time has been devoted to modeling and casting Indian 
busts, casting fossils, medals and archeological objects, and repairing 
and otherwise caring for the numerous lay figures and lay-figure 
groups. 
DEPARTMENT OF BIOLOGY. 
The largest and most noteworthy accession of the year in the 
department of biology was that received from the Smithsonian African 
Expedition, under the direction of Col. Theodore Roosevelt, of which 
an account is given under the head of explorations. The collection 
is especially rich in mammals and birds from east Africa, though 
other groups are well represented. The United States Bureau of 
Fisheries made several large and important transfers, consisting 
mostly of material which had been studied and described, and includ- 
ing many types. Another important source of material was the expe- 
dition to Java by Mr. Owen Bryant, of Cohasset, Massachusetts, 
accompanied by Mr. William Palmer, of the Museum staff. The 
collection, in which the Museum shares equally with Mr. Bryant, 
represents a wide range of subjects. 
Mammals.—Besides the material from Africa and Java, above 
referred to, the more noteworthy additions of mammals comprised 200 
specimens from China, of which the majority of the species represented 
were new to the Museum, collected by Mr. Arthur de C. Sowerby; 
139 specimens from eastern Borneo, collected and presented by Dr. 
W. L. Abbott; and 30 specimens, including a rare monkey and a 
giraffe from the type localities of the species, donated by Mr. John J. 
White, of Washington, District of Columbia, by whom they were 
obtained during a hunting trip in British East Africa. Twenty-three 
interesting Australian mammals were received in exchange from the 
Western Australian Museum and Art Gallery at Perth. 
During the first nine months of the year the work of this division 
was chiefly of a routine character, and much progress was made in 
arranging and labeling the skulls of rats, mice, and bats, and the skins 
of several genera of rodents, of which there are large series. In April, 
1910, the general reserve collection was moved to the new building, 
where it now occupies the entire ground floor of the northwest range, 
and the mammal collection of the Biological Survey, the adjacent 
west range. The increased space and facilities in these quarters 
permit a thorough overhauling of the material and a careful systematic
