The specific gravity of a fragment was 6,949. 

 The following analysis was kindly furnished by Prof. F. P. 

 Venable, of the University of North Carolina: — 



Fe 93.39 



Ni 5.62 



Co 58

The iron is the mean of three fairly agreeing determinations; 

 the nickel, of two determinations, 5.61 and 5.63; the cobalt, of 

 two determinations. The phosphorus is a single determination. 



I take great pleasure in thanking Prof. Eugene A. Smith for 

 his courtesy in obtaining the iron, and Prof. F. P. Venable 

 for furnishing the analysis. 



METEORIC IRON FROM COLFAX TOWNSHIP, RUTHERFORD 

 COUNTY, NORTH CAROLINA. 



BY GEORGE F. KUNZ. 



This mass of meteoric iron was found by Amos Franklin, in 

 the spring of 1880 or 1881, while working on the farm of Mrs. 

 E. W. Dedmon, of Colfax Township, Rutherford County, 

 North Carolina. As the specimen was found on the ground im- 

 mediately after ploughing, it had evidently been turned up by 

 the plough. It was then thrown on a wood-pile near the house, 

 and was frequently beaten with an axe. A small piece was 

 broken off by Mr. John Wilks, of Mecklenburg Iron-Works at 

 Charlotte, N. C, on February 7th, 1890, and sent by him to 

 Stuart W. Cramer, assayer in charge of the United States Assay 

 Office at Charlotte, who identified it as meteoric iron. 



Its weight is 72 ounces Troy, — 2,400 grammes. It is about 

 the size and shape of a double gourd, with three or four large 

 indentations. The surface is slightly rusted, but there are still 

 traces of black magnetic oxide of iron. At one end, wliere it 

 was broken, the octahedral structure shows beautifully, and 

 several octahedral cleavages are seen. In structure, it is very 

 similar to that from Jenny's Creek, Wayne County, West Vir- 

 ginia {Am. Jour. ScL, Vol. XXXI., Feb., 1886, p. 145), but it 

 is tougher in its fracture. The etclied surface shows the Wid- 

 manstatten figures very finely, — the markings being somewhat 

 smaller than in the Griorietta Mountain meteorite. Between the 

 cleavage laminae are plates of schreibersite.
