taking a very high polish, and exhibitin 
color rather whiter than that of steel. It shows no crystalline 
figures on being corroded with nitric acid; although on very close 
inspection, minute, whitish spots, (isolated and collected into 
patches,) may be seen here and there, scattered without order 
over the surface. When broken, it presents a fine granular tex- 
was probably too high, and that the compound might contain 
other ingredients. My own specimen affords me, iron 85:30, 
nicke] 14-70, with traces of calcium, magnesium and aluminium.

8. Burlington, Otsego county, N. Y¥.—This mass (originally 
150 Ibs. in weight) was described by Prof. Srutman, Jr., in Vol. xlvi, 
p. 401, (1844.) It was ploughed up by a farmer, near the north line 
uses; until its weight was diminished to about a dozen pounds, 
when it fortunately fell into the hands of Prof. Hadley, of Geneva, 
N. Y., to whom I am indebted fora conical lump, (weighing nine 
pounds, ) which must have formed a somewhat pointed extremity 
of the original mass. From the base of this, a slice was taken, 
leaving a lump of five pounds of the annexed form. Its sides 
show for the most part, the natural crust of the iron; but where this 
is not the case, the surface has been cut and polished, or 1s coarsely 
crystalline with large tetrahedral and sub-hackley faces, occa- 
sioned by the breaking off of what were apparently oe 
prongs. Its polished faces show a very high lustre, with a color

much charged with amygdaloidal kernels of magnetic iron pyrites, presents an un- 
commonly pitted and jagged surface.
