In its pure and fresh state it dissolves easily in water. If dropt on a woollen cloth, it will wash out easily, and leaves no stain. It is of an acrid, rough, pungent taste, is used by the Arabs in all complaints of the stomach and bowels, is reckoned a powerful antiseptic, and of use in preventing any infection of the plague. These qualities it now enjoys, in all probability, in common with the various balsams we have received from the new world, such as the balsam of Tolu, of Peru, and the rest; but it is always used, and in particular esteemed by the ladies, as a cosmetic: As such it has kept up its reputation in the east to this very day. The manner of applying it is this; you first go into the tepid bath till the pores are sufficiently opened, you then anoint yourself with a small quantity, and, as much as the vessels will absorb; never-fading youth and beauty are said to be the consequences of this. The purchase is easy enough. I do not hear that it ever has been thought restorative after the loss of either. The figure I have here given of the balsam may be depended upon, as being carefully drawn, after an exact examination, from two very fine trees brought from Beder Hunein; the first by the Cadi of Medina at Yambo; the second at Jidda, by order of Yousef Kabil, vizir or minister to the sherriffe of Mecca. The first was so deliberately executed, that the second seemed of no service but to confirm me in the exactitude of the first. The tree was 5 feet 2 inches high from where the red root begins, or which was buried in the earth, to where it divides itself first into branches. The trunk at thickest was about 5 inches diameter, the wood light and open, and incapable of polishing, covered with a smooth bark of bluish-white, like to a standard cherry-tree in good health, which has not above half that diameter; indeed a part of the bark is a reddish brown; it flattens at top like trees that are exposed to snow-blasts or sea-air, which gives it a stunted appearance. It is remarkable for a penury of leaves. The flowers are like that of the acacia-tree, white and round, only that three hang upon three filaments, or stalks, where the acacia has but one. Two of these flowers fall off and leave a single fruit; the branches that bear this are the shoots of the present year; they are of a reddish colour, and tougher than the old wood: it is these that are cut off and put into little faggots, and sent to Venice for the Theriac, when bruised or drawn by fire, and formerly these made the Xylo-balsamum. Concerning the vipers which, Pliny says, were frequent among the balsam trees I made very particular inquiry; several were brought me alive, both to Yambo and Jidda. Of these I shall speak in another place, when I give the figure, and an account of that animal so found. SASSA, MYRRH, AND OPOCALPASUM.
