326 C. U. Shepard on New Localities of Meteoric Iron. 
incrustation of peroxyd: on the contrary, it merely possesses for 
coating a thin, brownish-black pellicle, which is much covered 
also by firmly adhering clay. 
The iron is highly crystalline in its texture ; a fact which may 
be seen in a few spots upon the surface, even through the coating 
itself. It is exceedingly tough, breaking with the greatest diffi- 
culty, and having a hackly surface, in which no crystallization is 
apparent. The fresh surface is much whiter than pure iron; an 
it retains its color and lustre apparently without change from of- 
dinary exposure to the air. Its specific gravity = 7°30. 
A part of the broad cleavage surface (or base of the pyramid) 
above described, was polished, and acted upon by dilute “hydro- 
chloric acid. e corrosion was very partial ; but it revealed a 
perfectly crystalline structure in the iron. The subsequent appli- 
cation of nitric acid rendered it still more striking. Wi 
mannstattian figures are somewhat peculiar. While there 1s 4 
general ground subdivided by innumerable thin and perfectly 
straight lines, into small equilateral triangles, and oblique-angled 
parallelograms of similar areas in size, presenting a picture on the 
whole closely resembling the Guildford (North Carolina) iron, 
there are also irregularly disposed veins, or interrupted seams, of 
a shining, white metal, ,),th of an inch in thigkness, and eac 
. from 4 to 2? of an inch long. These occur on the whole pretty 
near together, and impart a singular aspect to the surface, 1as- 
much as the veins do not’coincide in direction with the fine lines 
above mentioned; nor do they follow any parallelism with one 
another. ; 
Neither of the acids employed attack this substance in the 
slightest degree, any more than they do the thin lines producimg 
the small and regular areas. But closely associated with the 
larger veins are noticeable small particles of magnetic pytite® 
which as usual are decomposed by the acid. :

seams, and heated it with acids, I convinced myself that Sal
