of a few ounces cut off by Prof. Everhart for analysis, which he seems 
to have not had time to complete. The thinner end had been pounded 
considerably, and some small fragments.may have been detached, so 
that when found the weight might possibly have been 180 lbs. The 
two greatest dimensions are 17% and 13 inches (44x33 centimeters). 
The general form is well shown in the accompanying cut. The 
underside is smoother and less sharply pitted than the upperside, which 
was probably the forward portion during the latter part of its flight. 
The iron, although very little oxidized, shows none of the characteristic 
stricee and ridges seen in irons that have recently fallen. 
The troilite seems to be distributed in comparatively thin plates, no 
nodules having been seen. The largest example is six inches in length,

and less then one quarter inch in average thickness, with an unknown 
width of certainly over two and one-half inches, is quite irregular in 
outline and terminates at one end in a star with points about one-half 
inch long. This form, which is very suggestive of certain marcasite 
crystalizations, seems to be quite persistent, showing substantially the 
same in different sections for two and one-half inches without any more 
indication of coming to an end than the plate with which it is 
connected. 
Prof. Josiah P. Cooke, who has examined two of the sections, 
writes “I do not see any farther signification in the star except the 
tendency of the troilite to separate along the planes of crystalization, 
and the union of these planes roughly marked gives the star.”
