Winchell and Dodge 3 also examined and described some individuals, their account being 

 in part as follows : 



A polished section of the 221-pound mass shows metallic iron as composing somewhat less than one-half the entire 

 surface and serves as a matrix in which are embedded amygdaloidal or roundish masses from the size of a pea to that of 

 a musket ball, and larger, of the black and yellowish minerals which comprise nearly the whole of the rest of the mass. 

 The iron framework of the whole mass is not regularly cellular, but with many partings and tortuous shapes it fits closely 

 about the concavities in which the minerals lie and gives firmness and shape to the whole. 



The Widmannstatten figures were brought out on this surface by etching. Some of the metallic iron does not 

 exhibit the characteristic bars, and generally there is a narrow marginal strip on all these surfaces that does not show 

 them.

But three minerals were detected in this meteorite by microscopic examination of thin sections, viz, olivine, 

 chromite, and troilite. 



The results differ somewhat from those of Kunz and the authors say: 



Whereas the analyses given by Kunz show the presence of a small amount of manganese oxide and ours show none, 

 our analyses indicate the presence of a considerable amount of chromium, and his show none. 



They also found the olivine masses in rounded forms, embraced in brilliantly lined cavities 

 within the metallic iron, but they did not distinguish any individual crystal faces nor exterior 

 angles. 



The probable relations of the Kiowa County meteorites to the meteoric material found in 

 the Turner Mound, Ohio, were discussed by Huntington 4 with the conclusion that there was no 

 proof that the two were identical. 



In 1S92 Hay 5 reported the finding of additional individuals as follows: 



This spring some more meteorites were found, which extend the area of the find as described by Kunz, Snow, and 

 Winchell nearly a mile farther east and increase the number of meteorites several thousand. One mass of 80 pounds 

 has been obtained, but the rest of the find represents a new feature in the remarkable fall. There has been one distinct
