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.

 nickel, copper, phosphorus and silicon, found in this iron by 

 others, I have detected cobalt.

 My first knowledge of this iron was derived from a remark, con- 

 tained in a letter from Hon. T. J. Clingman, 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 j 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 a 

 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, dated 

 June 1, 1846, accompanied by the specimen itself. " I can fi- 

 nish you with little that is definite concerning its history. The | 

 year Col. Nicholson, of Charleston, died, he had obtained it in I 

 Pendleton or Greenville District. It was given to him by some I 

 person, who had picked it up as a meteorite. Col. N. gave it to I 

 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/'
