Bismuth is used in the composition of pewter, in printers' types, and other metallic mixtures.
This metal is sometimes found native, but more commonly mineralized with sulphur.
LECTURE XXVII.
Of Nickel.
Nickel is a semi-metal of a reddish cast, of great hardness, and always magnetical; on which account it is supposed to contain iron, though chemists have not yet been able to separate them.
The purest nickel was so infusible as not to run into a mass in the strongest heat of a smith's forge; but then it was in some degree malleable.
Concentrated acid of vitriol only corrodes nickel. Alkalies precipitate it from its solution in the nitrous acid, and dissolve the precipitate. It readily unites with sulphur.
Nickel is found either native or mineralized with several other metals, especially with copper, when it is called kupfer nickel, or false copper, being of a reddish or copper colour.
