called also *tin-glass*, a ponderous brittle semi-metal, resembling zinc and the regulus of antimony, but differing greatly from them in quality.—Bismuth is sometimes found native, in small compact masses, of a pale lead-colour on the outside, but a tivery white within. It is very common in Germany, and not unfrequently found in the tin-mines of Cornwall, though little known, or at least regarded, there.
