REPORT OF THE SECRETARY. 31 
large and interesting series of costumes and accessories worn by the 
late Kicliard Mansfield in his extensive repertoire of historic char- 
acters, presented by Mrs. Mansfield. Many other historical relics 
were received, among them the gold medal awarded by act of Con- 
gress to Capt. Thomas Truxtun, United States Xavy, in recognition 
of the defeat of the French ship Vengeance, February 1, 1800, lent by 
Mr. Thomas Truxtun Houston ; a silver-mounted telescope owned by 
Thomas Jefferson, lent by Brig. Gen. Jefferson Randolph Kean, 
Medical Corps, United States Army; and a jeweled sword presented 
to Maj. Gen. John R. Brooke, United States Army, by American and 
Cuban friends in 1899. 
The operations of the curators of the divisions of ethnology and 
archeology in Arizona have added considerably to the collections 
in archeology, and Dr. W. L. Abbott has supplemented the material 
generously contributed by him in previous years from Celebes with 
a large series of costumes, ornaments, and implements collected by 
Mr. H. C. Raven. Especially interesting are the decorative de- 
signs on the bark cloth used for costumes on these islands. 
In j)hysical anthropology very important accessions from the 
ancient pueblo region were received through Mr. F. W. Hodge, as a 
gift from the Museum of the American Indian, and as a gift from 
Dr. EdAvin Kirk valuable crania and other physical remains from 
the territory occupied by the Haida and Tlingit tribes of Alaska. 
Biology. — The number of specimens received during the year by 
the department of biology, totaling about 482,740, vastly exceeded 
the number accessioned last year. This great increase was chiefly due 
to the incorporation of the unrivaled collection of Antillean land 
mollusks, aggregating approximately 400,000 specimens, which was 
donated by Mr. John B. Henderson, a regent of the Smithsonian 
Institution. It is one of the most complete and extensive collections 
of its kind in existence not only because it contains nearly all the 
known West Indian species but because of the large number of types 
and authentic specimens which it includes. Among the many other 
important collections received, it may be well to mention the final in- 
stallment of Mr. Raven's Celebes collections, which we owe to Dr. W. 
L, Abbott's generosity, and the interesting material from the Collins- 
Garner Expedition to the French Congo, containing as it does, 
besides a large number of birds and smaller mammals, three gorillas 
and several chimpanzees. Secretary Walcott, during his explorations 
in British Columbia, collected several large mammals for the Museum, 
including a mule deer, Rocky Mountain goat, and Rocky Mountain 
sheep, which made a valuable addition to our collections. 
Among the additions to the National Herbarium may be particu- 
larly mentioned about 12,000 plants, chiefly from Mexico, donated by 
Brother G. Arsene and representing the result of eight years' botani-
