REPORT OF THE SECRETARY. Ill 



feature of the work of the Institution, two series of reproductions of paintings were 

 exhibited, one representing the history of painting and the second tiie history of 

 portraiture. These two important topics could be illustrated only in outline on 

 account of limited space, Init the series included reproductions of a considerable 

 number of the greatest paintings and portraits of all epochs and schools. 



In addition, the exhibit of the Institution included a comi)lete set of its publica- 

 tions and those of its bureaus; portraits of the secretaries; personal relics of James 

 Smithson; a cast of the bronze tablet recently i:)laced on the tomb of Smithson at 

 Genoa, Italy; a copy of the seal of the Institution; objects and papers relating to 

 the Hodgkins fund, including publications, medals, and a portrait of the founder, 

 Thomas G. Hodgkins; two large photographs of the aerodrome of Secretary Lang- 

 ley; a picture of the Smithsonian building; and co])ies of the history of the first 

 half century of the Smithsonian Institution. 



The exhibit of the Institution was installed in the extreme northwest corner of 

 the building. It was asseml)led, under the direction of the Secretary, by Dr. Kichard 

 Rathbun, Assistant Secretary. 



BUREAU OF AMERICAN ETIIXOLOGY. 



As already stated, this Bureau made no separate exhibit at Buffalo, l)ut coi)perated 

 with the department of anthropology of the National Museum. Dr. W J McGee, 

 of the Bureau of American P]thnology, made an expedition to Sonora, Mexico, for the 

 purpose of ol>taining a collection representing the arts of the Seri Indians. On 

 reaching their country, however, he found that the tribe was exterminated, and he 

 then turned his attention to the Cocopa Indians, from whom he obtained an impor- 

 tant collection. 



NATIONAL ZOOLOGICAL PARK. 



The chief exhibit of the park was an elaborate relief model showing the topo- 

 graphical features of the grounds and the location of the animal houses, paddocks, 

 ranges, and cages. This was sui^pleniented by photographs of some of the principal 

 houses and of picturesque points in the ])ark. 



HUREAU OF INTERNATIONAL EXCIIAN(iES. 



It will be appreciated that the work of the Bureau of Exchanges does not lend itself 

 to exhibition by material objects. The exhiljit at Buffalo consisted of a set of Govern- 

 ment publications such as are distributed annually to other governments throughout 

 the world, and a series of photograjjhs showing the interior of the offices of the Bureau 

 in Washington and the recei])t and dispatch of consignments of scientific publications. 



ASTKOPII YSICA L OBSERVATORY. 



The exhibit of this Bureau was selected and prejjared, under the direction of the 

 Secretary of the Institution. 



The princij)al object in the exhibit was a photograph of the infra-red end of the 

 solar spectrum, showing the work of the Observatory on this subject for a period of 

 years. The photograph was enlarged so as to have a length of about 20 feet, and 

 was displayed on the north wall. There was also exhibited a series of i)hotograplis 

 of the solar eclipse, as observed at Waynesboro, N. C. 



In a table case near by was shown a copy of Volume I of the Annah of the Astro- 

 physical Observatory, a new serial publication containing the results of the work of 

 the Observatory. The following objects were also exhibited: The bolometer, or 

 electric thermometer, an extremely sensitive instrument, the invention ot Mr. 

 Langley, used in measuring the heat of the invisible spectrum of the sun, the tem- 

 perature of the stars, etc. ; photographs of other instruments used in the Observatory, 

 Buch as the siderostat, galvanometer, and spectrometer; photographs ot the exterior 

 and interior of the Observatory buildings in the Smithsonian grounds.
