Notice of Prof. Clark’s Thesis on Metallic Meteorites. 21 
According to Manross, it contains cobalt.—38. Sierra Blanca, 
exico. Mentioued in the Gazeta de Mexico in 1784, where it 
is stated that masses of native iron weighing 2000 Ibs., 3000 lbs., 
and even more, had been found among these mountains. When 
etched, exhibits Widmannstattian figures, similar to those on the 
Durango mass.—39. San José del Sitio, Mexico. Discovered 
by Sonnesehmidt in the corner of a charch-yard in Chareas, par- 
tially buried in the earth. The projecting portion was 24 feet 
long and one foot in diameter. It was said to have been brought 
from the estate of San José del Sitio, where several masses had 
been found imbedded in a limestone, probably of tufaceous ori- 
gin.—40). Jackson County, Tenn.—41. Babb’s Mill, Tenn. 
Prof. Clark reanalyzed this iron, detecting 2037 p. c. of cobalt, 
and making the proportion of nickel as high as 17-1 p. e.—42.

from Mexico by Baron Karawinsky of Munich. The metal is 
compact, and exhibits on etched surfaces crooked bands, the erys- 
talline structure having been apparently distorted by hammering. 
Gr.=7:38, Rumler.—50. Greenland. Described by Capt. Ross 
in 1819. The attention of the Captain was attracted to it by 
the fact that the Esquimaux of the coast used implements of iron. 
Upon inquiry he learned that they procured the material from a 
large mass of native metal lying thirty miles inland, near which 
they informed him was a huge stone containing globules of me- 
tallic iron. It is very malleable, silver-white, and not easily ox- 
ydized. It contains nickel, pyrites, and a black unknown mine- 
tal, and when etched, exhibits fine crooked bands, the original 
Structure having been distorted by hammering. Gr.=7-23, Rum- 
ler, According to Brande contains 3 p. c. of nickel. id 
_, 51. Petropawlowsk, Altai, Siberia. Described by Sokolowskji 
n 1841. Several small specimens of meteoric metal were found 
at the depth of 314 feet below the surface. The largest mass 
Was of irregular form, and coated with a crust of hydrated oxyds. 
Its weight was 174 lbs. Gr.=7-76. Analysis by Sokolowskji.

_ 52. Alasej mountains, Siberia. Large quantities of excellent 
iron are said to be found among these mountains and to be em- 
oyed by the natives in the manufacture of knives, wedges, ete.
