about three parts of olivine to one part of iron. The iron in 

 the Carroll County meteorite is scarcely more than sufficient to 

 hold the mass together securely, as the olivine is in so much 

 larger crystals than in the Atacama meteorite. On etching, small 

 fine Widmanstatten markings are produced. By reflected light 

 minute crystals of bronzite can easily be recognized, and analysis 

 showed the presence of chromite in fine grains and a very small 

 quantity of schreibersite. 



Mr. Kunz also described 



A NEW METEOR FROM CATORZE, MEXICO. 



This mass, -weighing 92 pounds, was found by a miner near 

 Catorze, San Luis Potosi, Mexico, in 1885. It is 31. 5*='" (12^

inches) long, 34.5"" (13f inches) wide, and 20°'" (8 inches) 

 thick. It shows beautiful raised octahedral markings. On 

 one side an opening Q""^ (3^ inches) long has been made, and a 

 piece of a chisel of native copper left wedged in it. This 

 piece, which is partially covered with oxide of copper, is 22™"" 

 (I inch) long on one side, 33°^" (1^ inch) on the other, and 14°'°' 

 wide. 



This iron is one of the Caillite group of Stanilas Meunier 

 and shows the Widmanstatten lines very finely (see fig. 6). 



It resembles the irons of Augusta County, Virginia, of Glorieta 

 Mountain, and others of this group. No troilite was observed, 

 the mass having been cut very little, and schreibersite is only 

 sparingly present. 



The specific gravity of the piece is 7.509. An analysis has-
