When bromine water or dilnted nitric acid is applied to a 

 polished surface of tlie iron, it blackens and does not show the 

 Widnianstiitteu figures. If this black deposit is washed off, an 

 orientated sheen appears, which resembles that of the Green county 

 iron, described by Blake,* and the iron in the Port Orf )rd, Ore- 

 gon, meteorite, as figured by Brezina and Cohen in "Die Structur 

 und Zusammensetzung der Meteoreisen, etc."t Almost the 

 entire surface has, under the glass, the appearance of a mesh-work 

 of which the irregularly rounded centers have been eaten out. 

 At a few places on both sides of a crack is a small piece of troi- 

 lite 3 mm. by IJ mm., through which are scattered small patches 

 of meteoric iron that after etching exhibit beautiful octahedral 

 markings so delicate as to be invisil)le to the naked eye, and 

 somewhat like those of the Tazewell, Claiborne county, meteor- 

 ite, thouo-h not more than one-tenth the thickness.
