The iron as found was very badly oxidized, but is of interest as 

 being probably of prediluvial age. Structure octahedral.

BABB'S MILL, GREENE COUNTY, TENNESSEE. No. 98. 



Iron, Db. Weight, 38.4 grams. Date of fall unknown; found in 

 1842 and described by Troost in 1845; later (in 1876) a larger mass 

 was found which was described and figured by W. P. Blake in 1886. 

 The second find was remarkable for its peculiar shape, being 36 inches 

 long, 10 inches broad, and 6 inches in thickness, with a girth, of 24 

 inches. (See Cast No. 291.) It belongs to the group of structureless 

 irons, ataxites, and shows no figures on an etched surface. The chemi- 

 cal composition as given by Cohen and Weinschenk is : 



Ter cent. 



Iron (Pe) 86.30
