 then be : Nickel-iron, 5.34 ; troilite, 3.85 ; olivine and enstatite.

WALKER COUNTY, ALABAMA. No. 120. 



Iron, H. A thin slice some 2 by 3 cm. in diameter, weighing 15 

 grams, from a mass weighing about 165 pounds, or 74.5 kilograms, 

 found in 1832 in the northeast corner of Walker County. Excepting 

 that this iron is hexaliedral in crystallization, there is no apparent 

 reason for including it in the Lime Creek, Claiborne find, several hun- 

 dred miles to the southwest. 



WARRENTON, WARREN COUNTY, MISSOURI. No. 43. 



Stone, Ceo. Weight, 11 grams; fragment from interior. A fine, 

 somewhat loosely aggregated mass of a smoky blue-gray color. Fell 

 January 3, 1877, at 7 a. m. No re})ort nor luminous phenomena ac- 

 companied the fall, the only sound being that caused by its passage 

 through the air, which was compared to the whistle of a distant loco- 

 motive or the passage of a cannon ball. Struck a tree in falling and 

 portions of wood fibers adhered, wdiich, however, Avere not in the least 

 charred, indicating that the temperature was not high, though it was 

 reported that the snow was melted immediately around the spot 

 where it fell. Original weight estimated at 100 pounds (45.5 kilo- 

 grams), but only some 10 or 15 pounds (4 to 7 kilogi-nras) preserved.
