ULTRAMARINE. An expeditious and probably a cheap method of preparing this beautiful pigment, has lately been discovered on the continent, but it is still kept secret.
Adulterated frequently; but its genuineness may be ascertained by bringing it to a red heat in a crucible, when, if it is not genuine, it will become pale or blackish. When tried witgh oil, it assumes a brown tint.

UMBER, and Burnt Umber, are earthy pigments used in painting.

UVÆ URSI FOLIA. L. E. D. P. Uva Ursi, or Bear-berry Leaves. Arbutus uva ursi. A native shrub, but not common. It is chiefly usedon account of its astringency. It is also slightly diuretic. It is supposed to relieve nephritic and calculous complaints and vesical irritability by astringing the relazed mucuous membrane of the bladder, &c., and diminishing the secretion of mucus. The dose is €j to 3j of the dried leaves thrice a day. It frequently renders the urine black. It does not seem to merit much condidence.
Imitated by substituting the leaves of other plants for the genuine, which are oblong-egg-shaped, very entire, and veined like network underneath.
