earth-pitch; a fluid, opaque, mineral body, of a thick consistence, strong smell, readily inflammable, but leaving a residuum of greyish ashes after burning. It arises out of the cracks of the rocks, in several places in the island of Sumatra, and some other places in the East Indies, where it is much esteemed in paralytic disorders.

PISELÆUM INDICUM, Barbados Tar; a mineral fluid, of the nature of the thicker bitumens, and of all others the most approaching, in appearance, colour, and consistence, to the true pissaphaltum, but differing from it in other respects. It is very frequent in many parts of America, where it is found trickling down the sides of mountains in large quantities, and sometimes floating on the surface of the waters. It has been greatly recommended internally in coughs, and other disorders of the breast and lungs.
