Dakota and the Bureau of American Ethnology. These specimens 

 are of much importance to the division. 



Mr. Hugo AVorch, of Washington, D. C, added to the Worch col- 

 lection a copy of the Bach harpsichord and a dulcitone and 11 other

The section of ceramics received a set of Japanese porcelain given 

 Prof. Joseph Henry by the first Japanese minister to the United 

 States, bequest from Miss Caroline Henry. Miss Freeman and Mrs.

 decorated Japanese plaques. 



Biology. — From the numerical standpoint, as well as from the 

 standpoint of the scientific interest of the collections, the year was 

 a very prosperous one for the department of biology. The outstand- 

 ing features of this year's accessions are the Australian collections 

 made by Mr. Charles M. Hoy, which were the result of Dr. W. L. 

 Abbott's continued interest in the Museum, and the great collection 

 of Japanese mollusks donated by Mr. Y. Hirase, of Kioto, Japan, one 

 of the most valuable accessions that has ever come to the division 

 of mollusks. Dr. Abbott is also responsible for the addition of an 

 important collection of birds and mammals made by Mr. C. Boden 

 Kloss in Siam, Cochin China, and Anam. While engaged in geo- 

 logical work in the Rocky Mountains, Secretary Walcott procured 

 for the Museum several desired Canadian mammals, including mule 

 deer and mountain goats. Another valuable accession is that of Dr. 

 J. P. Iddings's collection of butterflies and moths, presented by the 

 heirs of Dr. Iddings, consisting of about 2,500 named species, mostly 

 from the Tropics and mounted ready for exhibition. Through the 

 continued generosity of Mr. B. H. Swales, bird skins, representing 

 38 species and 7 genera not hitherto contained in the national col- 

 lection, were added. The botanical material accessioned during the 

 year embraced over 14,000 specimens from Haiti and Santo Domingo, 

 collected by Dr. Abbott and Mr. Leonard, besides a large number of 

 valuable collections both from the Old and the New World. 



Geology. — The additions to the collections in this department 

 showed a marked increase over those recorded in any one of the past 

 15 years. The total number of accessions listed is 231, a gain of 51 

 over last year and of 20 over the number recorded in 1914-15, next 

 highest on the list. 



The greatest bulk of material was received by transfer from the 

 United States Geological Surrey, but numerous valuable specimens
