meteoric iron from Nebraska. omy pvp at gave at the meet- 
ng ‘of ne Imp. Acad. of Vienna of Dec. 13, 1860, some information re- 
garding the meteoric iron from eee obtained by Mr. Nathaniel 
Holmes of St, Louis, Mo. 
The or ee mass weighed 35 pounds and was found on the right 
shore of the Missouri River i in Nebraska Territory, 25 miles west of Fort 
Pierre, 44° 19/ lat.,and 100° 26’ W. of Greenw., whence it was brought 
in 1857 and presented to the Academy of St. Louis in 1858. ~It venine 
803 pounds and the surface was hardly acted upon by rust. According 
to an analysis by Dr. H. A. Frat it contains : 
Iron, - » == 94'288

but not the least trace of cobalt, chrome, manganese or any other ¢con- 
stituent. e Widmannstadtean figures, however, would indicate the 
presence of iia hid of iron and nickel. 
A segment of the Vienna specimen cut nearly parallel with an oetahe- 
— plane showed strize of half a line in width epee at age of 
° and 120°, wi ith the triangular and rhombic intervals betwee at

on account of the numero flat depressions, which it shows, evidently
