5. Meteoric Iron of Chihuahua, Mexico. 
For the description of this meteorite, I am indebted to the 
fragment of it for examination from Dr. Webb, who detached 
pieces from the mass; but when applied to, they were no longer 
in his possession. It exists at the Hacienda de Concéption, about 
fen miles from Zapata. “The form is irregular’ Its greatest 
height is forty-six inches ; greatest breadth thirty-seven inches ; 
circumference in thickest part eight feet three inches. Its weight 
a given by Senor Urquida, is about three thousand eight hun- 
dred and fifty-three pounds. It is irregular in form, as seen by the 
figure ; and one side is filled with deep cavities, generally round 
and of various dimensions. At its lower part, as it now stands, 
iS @ projecting leg, quite similar to the one on the meteorite at 
Tucson. The back or broadest part is less jagged than the other 
Portions, and contains fewer cavities, yet, like the rest, is very 
Wregular,” 
n said in the text. it will be seen to be olivine, the chladnite of the Bishopville 
stone not being attacked by acid, or only to a very feeble extent, by boi mar gul- 
Phurie acid. And I would here remark that from some investigations just made, 
chladnite is likely to prove a pyroxene.—J. L. s.
