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 IMr. Henry W. Hendley, assisted hj 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 modelmg and casting Indian 

 busts, casting fossils, medals and archeological objects, and repaii'ing 

 and otherwise caring for the numerous lay figures and lay-figure 

 groups. 



DEPARTMENT OF BIOLOGY. 



The largest and most noteworthy accession of the 3'ear 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 IVIi'. 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 Cliina, of wliich 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 Wasliington, 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 overhauhng of the material and a careful systematic
