throughout with thousands of brilliant points of metallic iron, having very nearly the color and luster of polished silver. 

 The iron is rarely in points larger than a small pin's head, but the points are so numerous that nearly the whole of the 

 powder of the stone is taken up by the magnet, even when it is in fine dust, and by a magnifier the little points of iron 

 can even then be seen standing out from the magnet. It greatly resembles the Tennessee meteorite. 



It has the usual black crust on certain parts, and this, although resembling a semifusecl substance, exhibits bright 

 metallic points when a file is drawn across it. A similar black crust is seen pervading the stone in some places through 

 its interior, and forming, where it is seen in a cross fracture, black lines or veins. The stone is full of semifused black 

 points and ridges similar to the crust, and its entire mass seems half vitrified in points, so as to resemble an imperfect 

 glass. The specific gravity, as ascertained by Mr. Shepard, is 3.37. 



Shepard 2 gave an analysis of the meteorite as follows: 



Having been supplied, through the kindness of President Church and Professor Jackson, of the University of 

 Athens, with a specimen of this scarce stone weighing half a pound, I have been able to subject it to analysis, as well 

 as to determine its specific gravity more accurately than I had been able to do before. It is 3.52. It contains the 

 following ingredients: 



Nickel-iron (Fe, 89; Ni, 9.6; Cr and loss, 1.4) 10 



Howardite 70 



Olivinoid and anorthite 10-15 



Magnetic pyrites 2-5 



Apatite Trace

Brezina, in 1885 3 placed this meteorite among the unveine4 white chondrites; but in 

 1895 4 he placed it among the veined white chondrites, remarking that both of the Tubingen 

 specimens, one of 2 and the other of 59 grams, were veined white chondrites. 



Wulfing 5 is able to account for only 741 grams, which is distributed. In addition Am- 

 herst has 6 J ounces (about 170 grams). Wulfing's query, as to whether the main mass is at 

 Athens, Georgia, in the University of Georgia, was answered in the negative in a letter received 

 by the writer from the Chancellor of that institution.

FORSYTH COUNTY. 



Forsyth County, North Carolina. 



Latitude 36° 5' N., longitude 80° 15' W. 



Iron. Nickel-poor ataxite, Nedagolla group (Dn) of Brezina. 



Found, 1894; described, 1896. 



Weight, 22£ kgs. (50 lbs.). 



The history and characters of this meteorite have been summarized by Cohen 3 as follows: 



E. A. de Schweinitz states that this iron was found on a farm in the southwestern part of Forsyth County, North 

 Carolina, by a plowman, that it weighed about 22.5 kg., had an irregular wedge-shaped appearance, and was covered 

 with a thin coating of rust. The iron was extraordinarily tough and yielded no Widmannstattian figures upon etching, 

 but showed a dappled crystalline structure. 

 His analysis gave:

When, upon the ground of its chemical composition, de Schweinitz expressed the belief that this was a part of the 

 Guilford County meteoric iron it appeared to be entirely without foundation. On the one hand the latter is an octa- 

 hedral iron, on the other hand the analysis by Shepard used for comparison of the two may not be correct. 



Stiirtz, who obtained the block from G. F. Kunz in New York, requested me to examine and describe it more 

 exactly. I was the more ready for the task inasmuch as Schweinitz had not given sufficient information concerning the
