interspersed triangular figures, distinct enough to be easily seen 
with the naked eye, but under a microscope exceedingly beau- 
tiful. They resemble somewhat in this respect, the Bitburg iron, 
to which it also approximates in the tuberose conformation of the 
exterior surface. 
Hardness about that of grey cast iron. Sp. gr. = 7°32. 
It is composed of iron, (with traces 98-19 
of chromium and cobalt, ) ‘

The yellowish, olivine-like grains consist of silicic acid, lime,

nickel, copper, phosphorus and silicon, found in this iron by 
others, I have detected cobalt.

16. Black Mountain, head of Swannanoah River, eastern line 
of Buncombe county, (fifteen miles east of Asheville,) N. C.— 
My first knowledge of this iron was derived from a remark, con- 
tained in a letter from Hon. T. J. Crixeman, dated Feb. 17, 1846, 
to the following effect: “Dr. Hardy informs me that he gave a 
very remarkable looking specimen of meteoric iron found in this 
county, (Buncombe,) to the late Col. Nicholson of Charleston, 
S. C., who died at Abbeville in that state, six or seven years ago.” 
Being in Charleston, I applied to the executors of Col. N. for infor- 
mation respecting that portion of his effects, which would be likely 
to include this specimen ; but my inquiries were without success. 
Previous to this date however, I had been informed by Prof. 
Tuomey, who was then the state geologist, that he had seen 4 
specimen of malleable iron in the cabinet of Dr. Barratt of Abbe- 
ville, which led me to address a letter to this gentleman, relative 
to the subject, from whom I received the following note, dat 
, 1846, accompanied by the specimen itself, “I can fur- 
nish you with little that is definite concerning its history. The 
year Col. Nicholson, of Charleston, died, he had obtained it in 
Pendleton or Greenville District. It was given to him by some 
person, who had picked it up as a meteorite. Col. N. gave it 10 
me, as I was the only person in this part of the country who pre- 
served such objects. I believe it to be meteoric in its origin, and 
as such it has had a place in my cabinet. To yourself and to 
Science, it is most cheerfully tendered.”
