earth of Strigonium, in the materia medica, a red earth, of the bole kind, found about the gold-mines at Strigonium in Hungary, and used in some places as an attrigent and sudorific.

It is but of a coarse and impure texture, and lighter than most of the boles in colour; it is of a strong, but dull red, and is of a tolerably smooth surface; it is apt to crumble to pieces between the fingers, and stains the skin in handling; it melts freely in the mouth, and has a remarkable smoothness, but very little attrigency in its taste, and leaves a sensible grittiness between the teeth; it is sometimes veined and spotted with small molecules of an earth, like the whitish variegations of the red French bole.
