together with, examples of the medals awarded in 1895 to writers of essays compet- 

 ing for the Hodgkius fund prizes, and copies of the prize memoirs which had heen 

 published. 



On the wall adjacent was a cast of the memorial tablet which had recently been 

 placed, by order of the Board of Regents, on the tomb of Smithson, in Genoa, Italy. 



Two enlarged photographs of Secretary Langley's aerodrome (flying machine), 

 which twice flew over one-half mile on May 6, 1896, near Quantico, Va., were also 

 ■exhibited. The photographs were of different views of the machine, and two-fifths 

 its actual size. 



BUREAU OF AMERICAN ETHNOLOGY. 



The exhibit of this Bureau consisted of one-half of a Kiowa camping circle in 

 miniature, the material for which was collected by Mr. James Mooney, of the 

 Bureau. 



The entire exhibit was the work of Kiowa Indians, the insignia emblazoned on the 

 tepees and shields being executed, almost without exception, by those having an 

 inherited right to bear them. This aboriginal tribe is now the only representative 

 of a distinct stock or linguistic family of priscan people. 



Owing to the restricted space available, the skin tents were reduced from 16 or 18 

 feet in height to about 2h feet, while their number was reduced from about 150 (half 

 of the 300 or more tents forming the entire circle) to 25, exclusive of the ceremonial 

 lodges within the circle. 



The exhibit was prepared and installed by Mr. James Mooney, under the direction 

 of Mr. W J McGee. 



NATIONAL ZOOLOGICAL PARK. 



The extent and topography of the National Zoological Park were well shown in 

 the model exhibited, on which the buildings, roadways, and bridges, and the woods, 

 creek, and other natural features were faithfully represented. 



In the windows along the Smithsonian section were several transparencies, includ- 

 ing one of the carnivora house, one of the bridge, and one of a buffalo. There 

 were also exhibited three water-color paintings and one drawing, the work of Mr. 

 Glenn Brown, illustrating other attractive features of the park. 



BUREAU OF INTERNATIONAL EXCHANGES. 



A principal exhibit of this bureau was a complete set of the publications of the 

 United States Government for one year, being one of the fifty sets, such as are dis- 

 tributed annually by the bureau to libraries throughout the world. 



On the wall was a large map showing the geographical distribution of the corre- 

 spondents of the Institution, 24,000 in number, as entered on the registers of the 

 Bureau. 



Near the map was a diagram illustrating the number of publications, including 

 books and pamphlets interchanged between each State and Territory in the Uuited 

 States and foreign countries during the ten years preceding January 1, 1896. 



The exhibit was prepared by Mr. W. I. Adams. 



ASTRO -PHYSICAL OBSERVATORY. 



The exhibit of the observatory consisted of photographs of the exterior and inte- 

 rior of the building located on the Smithsonian grounds, and of the principal 

 instruments, such as the siderostat, galvanometer, spectrometer, and water-jacketed 

 bolometer and rheostat. Enlarged photographs of portions of the spectrum of the 

 sun were also exhibited. With these objects was a bolometer, or electrical thermom- 

 eter, of extreme delicacy, the invention of Mr. S. P. Langley.
