Polished Slice of the Cedar, Fayette County, Texas, Meteoric 

 Stone, about two-thirds natural size 



The polished surface shows a dark, compact margin thickly studded with particles of troi- 

 lite and some nickel iron (white m the figure). The veins, or properly the cracks, cutting 

 across the surface are emargined by like narrow, compact borders carrying the same con- 

 stituents. Tht intermediate gray portions are full of pits or cavities, also showing in 

 white, which at first sight seemingly result from the removal of the metal and mefallic 

 sulphide. (Seep. 558.)
