grained colophonite garnet, or the coccolite variety of pyroxene. It is, however, more or less traversed by cylindrical 

 or almond-shaped masses of meteoric pyrites, some of which are above an inch in length and one-third of an inch in 

 diameter. 



When polished it approaches more nearly to a silver- white color than any other meteoric iron. When acted upon 

 by acids it does not give the Widmannstatten figures, but only develops a series of weblike meshes, or, at most, a 

 mottled, maplike delineation. 



Its specific gravity =7.07. A fragment, as nearly as possible free from pyrites, was found to contain 3.32 per cent 

 of nickel. It is rich in chromium, and contains traces of phosphorus, cobalt, magnesium, and calcium. 



Brezina 3 in his 1885 catalogue grouped Union County with Nelson County as a breccialike 

 octahedral iron (Obn). He remarks that Tschermak considered them brecciated hexahedrites 

 but that such a classification is incorrect because Nelson County at least shows evident meshes 

 inclosed by teenite. He therefore classed them as coarsest octahedrites of the Seelasgen group, 

 having a brecciated appearance on account of the very changeable width of the bands. In 

 1895 5 he abolished the subgroup, however, and classed both Nelson County and Union County 

 simply as coarsest octahedrites (Ogg) . 



Meunier 4 classed Union County as nelsonite and gave the following as the elementary 

 composition, presumably as the result of analysis :

Little of the meteorite appears to be extant but more must have been obtained than the 

 1 pound 1.75 ounces described by Shepard, as the Amherst collection possesses 2 pounds 8 

 ounces. Wiilfing fists 711 grams, of which the Washington Shepard collection possesses 124 

 grams.

Tins meteorite was described by Smith x as follows : 



The Wisconsin meteorite which fell on March 25, 1865, and is one of much interest, attracted no attention at the 

 time of its fall outside of the immediate neighborhood where it was observed, a fact due to the comparatively sparsely
