shown the specimens of stone meteorites or aerolites. These 
specimens are in part individuals and in part fragments. They 
are arranged in chronological order passing from left to right. 
Specimens of about one hundred and fifty falls are shown. These 
include 660 individuals of the Forest City, Iowa, fall, about 
twenty individuals of Pultusk, Poland, and large masses from 
Farmington, Kansas, Saline, Kansas, Homestead, Iowa, Bluff, 
Texas, Estacado, Texas, etc. The rare carbonaceous meteor- 
ites are well represented by specimens from Orgueil and Alais, 
France, and Mighei, Russia. 
Following the stone meteorites are shown the iron-stone 
meteorites, of which about twenty-five distinct falls are repre- 
sented. These contain more iron than the stone meteorites and 
thus pass toward the iron meteorites. The iron varies in quan- 
tity from coarse flakes or nodules scattered among the stony 
minerals to sponge-like masses in which the stony portions are 
held. Complete individuals of the Crab Orchard, Tennessee, 
and Admire, Kansas, meteorites are shown, while other falls are 
represented by sections. In the same case are shown specimens 
of terrestrial iron which has a composition resembling that of 
meteoric iron. Santa Catharina, Brazil; Ovifak, Greenland; and 
Awarua, New Zealand, are among the localities thus represented. 
Following the iron-stone meteorites are placed the iron me- 
teorites, about one hundred and thirty falls of which are repre- 
sented. The specimens are chiefly sections and most of these 
are polished and etched in order to show the characteristic fig- 
ures. Especially well represented falls are those of Kenton 
County, Kentucky, Rodeo, Mexico, Indian Valley, Virginia, and 
Colfax, North Carolina. 
The casts in the bays of the cases show the form, size, and 
surface characters of the meteorites represented. As the me- 
teorite itself is usually cut up and distributed these casts afford 
the only record of such characters. Meteorites of remarkable 
form thus represented are those of Babb’s Mill, which is cigar- 
shaped, those of Kokstad and Hex River, South Africa, shaped 
like a large lower jaw, and Charlotte and Boogaldi which are 
drop or pear-shaped. A conical shape is also common, the apex 
of the cone having been the front side in falling. 
On the north wall of the hall is a large map showing the dis- 
tribution of known meteorite falls in the United States.
