C. A. Joy on a Meteorite from Chili. 243 
Art. XXV.—Analysis of a Meteorite from Chili; by CHARLES A. 
Joy, Professor of Chemistry in Columbia College, New York. 
THIS meteorite was found on a mountain pass, about fifty 
miles from Copiapo, in the province of Atacama, Chili, by a na- 
tive of the Argentine Republic, and presented to Mr. Joseph 
Brower, by whom it was brought to New York, and to whose 
kindness I am indebted for the fragment used in the analysis. 
The original specimen has been deposited by Mr. Brower, with 
a large collection of rare silver and copper ores from Chili, in 
the mineralogical cabinet at Union College, Schenectady. 
he outer crust of the meteorite wore the usual dark red color 
of oxydized iron. Its weight, uncut, was 1784 grams. ‘The 
specific gravity is 4°35. A polished etched surface gave an im- 
es on paper of scattered points rather than of regular lines. 
t also readily reduced copper from its solutions. 
close inspection of the specimen shewed that there was a 
large per-centage of stony matter interspersed through the mass, 
The color and hardness of a portion of this indicated olivine; 
other fragments recalled the appearance of partially decomposed 
labradorite. An unsuccessful attempt was made to withdraw 
the iron by means of a magnet, but the powdered mineral ad-
