SECRETARY OF THE SMITHSONIAN INSTITUTION

FOR THE YEAR ENDING JUNE 30, 1911. 
To the Board of Regents of the Smithsonian Institution: 
GrNnTLEMEN: I have the honor to submit a report showing the 
operations of the Institution and its branches during the year ending 
June 30, 1911, including the work placed by Congress under the direc- 
tion of the Board of Regents in the United States National Museum, 
the Bureau of American Ethnology, the International Exchanges, 
the National Zoological Park, the Astrophysical Observatory, and the 
United States Bureau of the International Catalogue of Scientific 
Literature. 
The general report reviews the affairs of the Institution proper, 
with brief paragraphs relating to the several branches, while the

work. Independently of the present report, the operations of the 
National Museum and the Bureau of American Ethnology are fully 
treated of in separate volumes.
