SANDAL, in antiquity, a rich kind of slipper worn on the feet by the Greek and Roman ladies, made of gold, silk, or other precious stuff, consisting of a sole, with an hollow at one extreme to embrace the ankle, but leaving the upper part of the foot bare.

Sandal, is also used for a shoe or slipper worn by the pope, and other Roman prelates, when they officiate. It is also the name of a sort of slipper worn by several congregations of reformed monks. This last consists of no more than a mere leatheren sole, fastened with latches or buckles, all the rest of the foot being left bare. The capuchins wear sandals; the recollets, clogs: the former are of leather, and the latter of wood.

SANDARACH, in natural history, a very beautiful native fossil, though too often confounded with the common factitious red arsenic, and with the red matter formed by melting the common yellow orpiment.

It is a pure sublimate, of a very even and regular structure, is throughout of that colour which our dyers term an orange-scarlet, and is considerably transparent even in the thickest pieces. But though, with respect to colour, it has the advantage of cinnabar while in the mass, it is vastly inferior to it when both are reduced to powders. It is moderately hard, and remarkably heavy, and; when exposed to a moderate heat, melts and flows like oil: if set on fire, it burns very briskly.

It is found in Saxony and Bohemia, in the copper and silver mines; and is sold to the painters, who find it a very fine and valuable red: but its virtues or qualities in medicine, are no more ascertained at this time, than those of the yellow orpiment.

Gum-SANDARACH, is a dry and hard resin, usually met with in loose granules, of the bignefs of a pea, a horse-bean, or larger; of a pale whitish yellow, transparent, and of a resinous smell, brittle, very inflammable, of an acid and aromatic taste, and diffusing a very pleasant smell when burning. It is produced from a species of the juniper.

It flows only from these trees in hot countries; but the natives promote its discharge by making incisions in the bark.

Sandarach is good in diarrhoeas, and in haemorrhages.

The varnish-makers make a kind of varnish of it by dissolving it in oil of turpentine or linseed; or in spirit of wine.
