J. W. Mallet—Meteoric Iron from Texas. 287 
A polished surface having been etched with nitric acid, 
Widmannstattian figures were clearly brought out, : e broa 
bands of crystalline nickel-iron (with finer subordinate mark: 
ings upon them) contrasting strongly with the ee sparingly 
occurring, well-defined, lustrous lines of schreiber, 
Chemical analysis of an average sample of he shavings 
taken off by a planing machine in cutting through the mass 
gave:

A separate examination of the troilite nodules proved them 
to consist of ferrous sulphide with a — pnts and traces of 
manganese and chromium. The nic may very possibly 
have existed in the form of minute granules of nickel-iron or 
schreibersite, and the chromium may in like manner be referred 
to an admixture of little particles of daubréelite. 
most interesting point about this specimen is perhaps 
the probability of its forming a separate portion of the same 
meteoric fall from which was derived the large iron meteorite, 
welgMng gies Ibs., first described by Col. Gibbs in 1814, and 
ich has long been a prominent object in the mineralogical 
in the northern part of the present Cherokee County, near the 
line of Smith County, and rather on the head waters of the 
Neches than of the Trinity, though not far from the latter, and 
about 240 miles from the locality in Wichita County where the 
meteorite now described was found. Even such a distance 
* Both of course variable with the distribution of schreibersite and troilite. 
+ Silica perhaps originally present as iron silicide—magnetic oxide iron doubt- 
less from outside surface
