This is evidently olivine, with a snnall amount of sulphide of 

 iron so dis-eniinated through the stone that it is not easily sepa- 

 rated by mechanical means. The meteorite then consists of 

 nickeliferous iron, bronzite and olivine with small particles of 

 anorthite and enstalite.

Randolph Meteorite. 



Locality — Randolph county. ^wa/^/s^— Shepard. 



This was first described by Prof. Olmsted in 1822, in a descrip- 

 tive catalogue of rocks and minerals collected by him, during 

 his geological survey of North Carolina. It is there spoken of 

 as occurring in the vicinity of a bed of argillaceous iron ore. 

 It is distinctly foliated, the laminse being thin and much inter- 

 laced. It weighed originally about two pounds. When etched it 

 presents very fine, almost invisible, feathery lines much resem- 

 bling hoar frost on a window-pane. Hardness equal to that of 

 the best tempered steel. Specific gravity=7.618. The only 

 metal detected, besides iron, was cobalt, which was present in 

 traces only. A reddish brown j)owder, insoluble in aqua regia, 

 was considered to be silicon.
