Report on Meteorites. 85 



who claimed to be the owner of the land, took me there, under 

 the impression that I should be able to aid him in discovering a 



and 



especially 



vicinity. The search of course was to no purpose. The mass 

 of one hundred and twelve pounds appeared to me to be identical 

 in character with the fragments I have seen of that supposed to 

 weigh a ton. 3 ' 



The sp. gr. of this iron, as given by Partsch, (Die Meteoriten, 

 p. 151,) is 7-26. I have found that of the included magnetic 

 iron-pyrites, to be 4-454.

Section 1st Pure. 



18. Randolph county. North Carolina. — This mass (origin- 

 ally two pounds in weight) was described by me in Vol. xvii, 

 p. 140, (1830.) as native iron. It had been previously mentioned 

 in Vol. v, p. 262, (1822,) by Prof. D. Olmsted, in a descriptive 

 catalogue of rocks and minerals collected by him, during his geo- 

 logical survey of North Carolina. It is spoken of by Prof. O., as 

 occurring in the vicinity of a bed of argillaceous iron ore. It is 

 distinctly foliated, the lamina} being thin and much interlaced. 

 Color and lustre resembling those of mispickel. When etched, 

 it presents very fine, almost invisible, feathery lines, much re- 

 sembling hoar frost on a window pane. Hardness equal to that 

 of the best tempered steel. Sp. gr. = 7*618. The only metal 

 I have been able to detect in this steel, is cobalt, and this only 

 in traces. A reddish brown powder, not soluble in nitro-hydro- 

 chloric ac id, did not communicate any color to a bead of borax, 

 which led to the suspicion that it was silicon. 



19. Bedford comity, Pennsylvania. — This variety was de- 

 scribed in Vol. xiv, p. 183, (1828,) as native iron, slightly arsen- 

 letted. It closely resembles the Randolph county specimen, in 

 structure, color, hardness and lustre. Its sp. gr. = 6915. In 

 the few grains at my command for its examination, I have been 

 unsuccessful in verifying the existence of arsenic, or of detecting 

 the presence of any other metal, besides iron. Still, its greater 

 analogy to the Randolph iron than to any other terrestrial pro- 

 duction, either natural or artificial, induces me to retain it in the 

 category of meteorites. 



Section 2d. Alloyed. 



20. Otsego county, New York. — The precise locality of this 

 Ve ry curious iron cannot at present be given. It came into my 

 Possession under the following circumstances. Two or three 

 Persons from Otsego county submitted a number of specimens to
