UNION COUNTY. 



Georgia. 



Latitude 34° 49 / N., longitude 84° 12' W. 



Iron. Coarsest octahedrite (Ogg) of Brezina; Nelsonite (type 5) of Meunier. 



Found 1853; described 1854. 



Weight, 6.8 kgs. (15 lbs.). 



This meteorite was first described by Shepard, 1 who states that a piece weighing 1 pound 1.75 

 ounces was brought him from a mass said to weigh about 15 pounds, found in Union County, 

 Georgia. Shepard further describes his specimen as follows: 



It appears to have formed a portion of a somewhat tabular mass about 2 inches in thickness. It is coated on three 

 sides with a thin scaly covering of brownish-black hydrated peroxide of iron. The other two sides present the appear- 

 ance of a fresh fracture but are, nevertheless,, destitute of metallic luster, the surfaces being very irregular and dependent 

 in form upon the peculiar concretionary character of the mass, which is strongly analogous to that of a very coarse-
