grams. Fell on the evening of February 12, 1875, at about half past 

 10 o'clock. Flight was from the south toward the north, about 18° 

 east, and was witnessed over a region at least 400 miles in length, 

 from southwest to northeast, and 250 miles in breadth. The velocity 

 with which it moved has been estimated at a maximum of 10 miles 

 a second. It was described as exploding like a rocket, and detona- 

 tions followed "so violent as to shake the earth and to jar the win- 

 dows like the shock of an earthquake." Over 100 irregularly shaped 

 stones were found, the largest of which weighed 74 pounds and the 

 aggregate of which was upward of 500 pounds.^ 



The composition of the stone as determined by J. L. Smith is as 

 follows : 



Per cent. 



Stony matter 81. 64 



Troilite 5. 82 



Nickel-iron 12. 54 



Of this stony part there was : 



Sohible in acid 54. 15 



Insoluble in acid 45. 85 



Analyses of these portions gave: 



These analyses show the stony portion to be a mixture of an iron- 

 rich olivine and enstatite. The composition of the metallic portion 

 was found to be: 



Iron 89.04 



Niclvel 10. 34 



Cobalt . 58 



with traces of phosphorus, sulphur, and copper. 



This stone has been described by Giimbel, Lasaulx, and Wadsworth. 

 The first named described it as entirely crystalline and fragmental 

 in character. Lasaulx states that it shows an evident brecciated 

 structure, with olivine gi'ains and rounded enstatite masses in a fine- 

 grained groundmass containing grains and fragments of crystals. 

 Wadsworth found no evidence of a fragmental structure, but regarded 



1 Wiilfing says some 700 pounds, the largest of which weighed 120 pounds. I can find 

 no authority for tbis.
