    YEL YTT 86? Xalappa. (From the province ofXa- Jappa, in New Spain, whence it comes.) Jalap. XANTHIUM. (From getv9o$, yellow; so named because it is said to make the hair yellow.) The lesser burdock. This herb Xanthium strumarium of Linnaeus, was once esteemed in the cure of scrophu- la, but like most other remedies against this disease, proves ineffectual. The seeds are administered internally in some coun- tries against erysipelas. Xanthium strumarium. The syste- matic name of the lesser burdock. See Xanthium. XERASIA. (From dry.) An excessive tenuity of the hairs similar to down. Xeropollyrium. (From Idry, and noMvgiov, a collyrium.) A dry collyrium. Yam. An esculent root, obtained ptin- cipally from three species of Dioscorea, the alata, bulbifera, and sativa. They grow spontaneously in both Indies, and their roots are promiscuously eaten as the pota- toe is with us. There is great variety in the colour, size, and shape of yams ; some are generally blue or brown, round or oblong, and weigh from one pound to two. They are esteemed when dressed as being- nutritious and easy of digestion, and are preferred to wheaten bread. Their taste is somewhat like the potatoe, but more luscious. The negroes, whose common food is yams, boil and mash them. They are also ground into flour, and made into bread and puddings. When they are to be kept for some time, they are exposed upon the ground to the sun as we do onions, and when sufficiently withered they are put into dry sand in casks, and placed in a dry garret, where they remain often for many seasons without losing any of their primitive goodness. Yarrow, common. See Millefolium. Yaws. The African name for raspberry. See Frambcesia. Yellow fever. See Febris continua. Yellow sounders. See Santalum album, Yorkshire sanicle. See Pinguicula. Xeromyrum. (From gwjo?, dry, and /cxvgov, an ointment.) A dry ointment. Xerophthalmia. (Sugo?, dry, and o<p9a,h/uta,, an inflammation of the eye.) A dry inflammation of the eye without dis- charge. Xiphium. (From a sword; so named from the sword-like shape of its leaves.) Spurge wort. XIPHOID. (Xiphoides, from go**, a sword, and sAo?, likeness.) A term given by anatomists to parts which had some resemblance to an ancient sword, a* the xiphoid cartilage. Xiphoid curtilage. See Cartilago ensi~ formis. Xyloaloes. See Lignum aloes. Xylobalsamum. See Balsamum gilea- dense, Ypsiloglossus. (From fiXonhg, the ypsiloid bone, and yx«crcra, the tongue.) A muscle originating in the ypsiloid hone, and terminating in the tongue. Ypsiloides. (From y, the Greek letter ypsilon, and sjS'o?, a likeness.) The os hy- oides, so named from its likeness to the Greek letter v ypsilon. YTTRIA. The heaviest of the earths. Its specific gravity is 4.842. It resembles glucine in several of its properties. It is smooth and insipid. It is infusible alone, but vitrifies with supersaturated borate of soda. It combines with the acids, and is precipitated from those solutions by ammo- nia and prussiate of potash. It is also pre- cipitated by tanmn. The precipitate is not soluble in acetous acid. As some of its salts are coloured, and its weight nearly approaches to that of metals, it is consi- dered as the link which connects the me- tals with the earths. It differs from glucine in not being soluble in fixed alkalies, nor being precipitated by the succinates. Its attraction for the acids is also generally stronger than that of glucine, and its saline compounds have not the same saccharine taste. Its other properties have not yet been examined. 3K2
