In 1834, Berzelius estimated the quantity of carbon to be 

 3.05 pr. ct. ; and Eoscoe, in 1862, made a careful examination 

 of the same meteorite. He determined the carbon present to be 

 3.36 in\ ct, 1.94 pr. ct. of the stone was soluble in ether, from 

 which, on eyajDoration, crystals were deposited that possessed 

 an aromatic odor, and were fusible at 114° 0. On applying 

 heat, they sublimed, leaving a slight carbonaceous residue. 

 Prof. J. Lawrence Smithf has also examined some of the same 

 material, and states the results of his investigation to be in 

 perfect accordance with those of Prof. Roscoe. 



In tbe meteorite which fell at Kold-Bokkeveld, Africa, Octo- 

 ber 13, 1838, Harris found 1.67 pr. ct. of carbon, and about 

 0.25 pi-, ct. of an organic substance soluble in alcohol; which 

 compound is said to have been of a yellowish coloi", and of a soft, 

 resinous aspect. 



The Kaba meteorite (Hungary), Ajn'il, 1857, has been analy- 

 zed by Wohler,J and found to contain 0.58 pr. ct. of carbon, 

 and besides this a hydro-carbon, resembling wax in appearance, 

 and soluble in alcohol, being extracted by this reagent. 



Carbon has been determined in several other meteorites :§ in the 

 one that fell in Sevier Conntv, Tennessee, 1840, by J. Lawrence
