Iron, though one of the most common of the metallic bodies, is not often found in the native state, in consequence of the powerful tendency which it possesses to combine with oxygen, sulphur, and other substances. Most of the existing specimens of native iron are supposed to have derived their origin from meteoric stones; though this metal is said to have occurred in the state of pure iron ore, massive, and in leaves of a grey colour, having a fracture like that of steel, and some degree of malleability. Some notice of meteoric stones will be found in another part of this volume; but besides those masses of ferruginous matter, undoubtedly of aerial origin, large blocks of iron in which the metal exists in various degrees of purity, have been discovered in different parts of the world ; and though these probably have been produced in the same manner with the acknowledged aerolites, yet since evidence is wanting as to the source whence they were derived, some account of them may here be added. Among these blocks of iron may be mentioned one found at EUenbogen in Bohemia; the large mass discovered by Professor Pallas, on the top of a hill, between Abakansk and Belskoi Ostrog, on the banks of the Jenesei, in Siberia, which originally weighed about 1680 pounds; a mass found in Southern Africa, and now in the cabinet of Haarlem, in Holland, weighing about 250 pounds; an immense mass of native iron from Otumpa, in the Gran Chaco Gualamba, in South America, described by Don Rubin de Celis, who estimated its weight at fifteen tons; a mass of ir...
