60 Dr. Walter Flight— On Meteorites. 



examination of it by Liclitenberger was made in the following year 

 (" Sitzungsber. der Isis," Dresden, 1873, p. 4). It is a rounded 

 block of malleable iron, weighing 25 pounds, and covered with a 

 blackish-brown crust of oxide. Like the meteoric irons of Ovifak, 

 Disko Island, Greenland, and many others, it contains chlorine, and 

 in damp warm air rapidly oxidises and exfoliates. The metal has 

 the grey colour of iron, does not exhibit the Wiedmannstiittian 

 figures, and has a specific gravity of 6'21 Geinitz finds the com- 

 position of this iron to be — 



Iron 93-04 



Nickel 6-16 



Phosphorus 0-22 



99-42 

 In the iron are many rounded, sometimes elongated, hollows filled 

 with a yellowish-brown mineral having the specific gravity =:3-98. 

 This on analysis was found to consist of — 



Iron 63-82 



Sulphur 37-36 



101-18 

 which showed it to be troilite (iron monosulphide), and to accord 

 in composition with the sulphide found in the meteoric iron of 

 Seelasgen. One cavity was filled with what appeared to be the 

 same mineral in a crystalline form. This is the first occasion where 

 troilite has been met with otherwise than massive. 



Found August, 1873.— Duel Hill, Madison Co., N. Carolina.^ 



A mass of meteoric iron was found in August, 1873, on the land of 

 Mr. Eobert Farnesworth, lying on a hill-side, where it had been used 

 probably by the first settlers to support a corner of a rail fence 

 smce rotted away. (A similar block, weighing about 401b., was 

 discovered about a mile further west, " before the war, perhaps about 

 1857," but has since been covered over and lost.) The mass above 

 referred to originally weighed some 251b. ; but specimens have been 

 hammered off it, and it now weighs 211b. and measures 9x6^ 

 X ?>\ inches. It has the usual coating of magnetite, and from 

 various points of the surface bead-like drops of iron chloride exude. 

 When polished and etched, "the usual markings appeared, though 

 rather indistinct," and when the action of acid was prolonged distinct 

 particles of Schreibersite were seen to protrude from the face of the 

 metal. The meteorite has a specific gravity = 7 -^S and the following 

 composition : —
