Gale'na [X.], or Sulphide of Lead, occurs native, and constitutes the chief ore from which most of the lead of commerce is obtained. (See Lead.) It possesses a bright bluish-white metallic lustre. It is sometimes found in Transition rocks, but more frequently in the Secondary rocks, especially in compact limestone. It occurs in beds and veins, and is found in almost every country. It is very abundant in Britain and in the United States. It is prepared artificially by adding sulphuric acid to a soluble lead salt.
