found the mixture of the minerals troilite, asmanite, and bronzite, of 

 an unaltered light brown colour, although they turn deep black when 

 raised to a temperature slightly above that at which lead melts. The 

 author's pages conclude with some considerations on the probable 

 temperatures of meteorites in their passage through our atmosphere. 

 1840.— De Calb Co., Caryfort, Tennessee.' 

 Brezina points out that in Tschermak's Catalogue- this iron is 

 described as compact, and in Eose's Beschreibung und Eintheibing it 

 is shown to resemble that from Babb's Mill. A fine section, acquired 

 from Professor L. Smith, shows it to be rightly placed near the irons 

 of Arva and Sarepta. Almost every band of kamacite, 1"5 to 3 

 millimetres across, carries a bar of porous schreibersite ; band-iron 

 and interstitial iron are sparsely present, and of a dull grey colour. 

 Two inclosed pieces of troilite, from 3 to 4 mm. diameter, are sur- 

 rounded by schreibersite from 1-5 to 2 mm. thick, and around this is 

 an irregular shell of beam-iron. 



1841, September 6th. — St. Christophe-la-Chartrense, Commune de 

 Eoche-Servieres, Vendee.'' 



The fall of this stone, which was accompanied by a double detona- 

 tion resembling thunder and a luminous appearance, took place in 

 the vineyards of St. Christophe at the above date. It created quite 

 a panic in the suiTounding country; on the first day none of the 

 peasants would approach it ; one could only look with fear in the 

 direction where it lay, it was said ; but on the following day a young- 

 man, w-ho was escorted to the spot, found it out and brought it away 

 with him. 



The stone weighs 5*500 kilogrammes, and is in the hands of a 

 proprietor who was neither disposed to communicate any information 

 respecting it, nor to allow any fragments to be removed. M. Daubree 

 has therefore to content himself with registering its existence, which 

 up to the present time has not been placed on record. 



Found about 1850. — Pittsburg, Alleghany Co., Pennsylvania.* 

 This large mass of meteoric iron, weighing 132 kilog., was turned 

 up by a plough at Pittsburg. It was briefly described at the time 

 by Silliman, and has now been analyzed by Dr. Genth. The 

 specific gravity appears to be 7*741 ; and the chemical composition 

 of a somewhat oxidized specimen was found to be 



Iron 92-809 



Nickel 4-665 



Cobalt ... 0-395 



Copper 0-034 



Manganese 0-141 



Sulphur 0-037
