thin, firm crust of dead-black, lead color or brown shade. A broken part shows a grey or reddish interior, of a granular, crumbling structure, often with large or small blotches of red, brown or yellow rust or oxyde. Also a polished surface is almost sure to reveal small grains or points of bright metallic iron. This latter character is the surest test and proof of a Stone Meteorite. The outside crust and the pittings are- one or both- a general, but not a constant feature.
A Stone Meteorite has no bandings or layers in the arrangement of its inner
particles, nor is there often any considerable difference in the general structure in different parts of the mass. A common variety of structure is a series of minute spheres or balls the size of coarse or medium shot which are sprinkled profusely through a base of more compact nature. Less commonly the structure is fragmentary, with small included fragments of stony matter slightly differing in composition from the main mass. In most Stone Meteorites the structure is granular and somewhat friable. In only rare cases is the mass crystalline, commonly not even dense.

are of more certain determination. They are simply chunks of iron, of almost any shape. They rarely have any thick or well-marked crust; but -unless they are much decomposed through long lying in the ground- pittings are apt to show on some part of their surface. They are tough like a mass of wrought iron, so that they may be sawed or filed; but it is with great difficulty that a piece can be broken off with a hammer. They are often confounded with masses of iron ore. But the latter is of granular structure,
