13^] LUP wort affords a larger proportion of ashes than ahnost any other plant ; the produce, in general, amounting to one-seventh part of its weight. LUPINE, or Liipimis, L. a ge- nus of exotic plants comprising nine species, most of which are cultivated in gardens, on account of their beautiful flowers : they are 3'aised from seed, which may be sown in any open borders, where they thrive, and present a pleasing variety. The seeds of the White Lu- pine (Lupimis alhiis) have a le- guminous, though disagreeably bit- ter taste, and are said to be vermi- fuge ; both when taken internally, and applied externally. Some au- thors, however, suppose them to be of a poisonous nature ; yet such seeds were much used by the Greeks as an article of food, and have been recommended by Ga- XEN as aifording wholesome ali- ment. — In the Transactions of the Patriotic Society of Milan (vol. ii. p. 243, Ital. edit.) there is an ac- count of the manner in which this plant may be converted into cord- ^(ige or ropes, and likewise into ■^aper.- — Beck stein says, that its flowers furnish the bees with abundance of honey. LUTE, a composition of certain viscid or tenacious matters, which becomes solid, when dry ; and %vhich, on being applied to the 5un6tures of vessels, closes them so effedually as to prevent the ad- mission or egress of air. Though lute is chiefly used by -phemists, it also comprehends any species of cement, applied to ves- sels, or furnaces, which are ex- posed to an ardent heat. It is va- riously prepared of rye-flour and V/ater; quick-lime and the whites of eggs 3 iron filings, bricK-dust, LUX and linseed- oil ; potters' earth, tU ver-sand, horse-dung, pulverizec} glass, or flocks of wool mixed with salt-water, or bullocks' blood. The best lute, however, and which is most easily procured in London, is IVindsor-lomn : it should be mo- derately stiff, so that, when moist- ened with water, it may be pressed into the side, or crevices, of the furnace, &c. As soon as the clay begins to dry, it must be beaten closely down to the sides, and the fissures repeatedly filled up, till the whole be perfeftiy closed. The late Dr. Black recom- mended a simple mixture of sand and clay, as preferable to any other composition. The proportions for resisting the violence of lire are, four parts of sand to one of clay ; but, if the lute be intended for lining or coating furnaces, he di- rects six parts of sand to be taken to one of clay, in order that the contraftion of the latter may be ef- feftually prevented. This com- pound is to be applied in a manner similar to that above stated, but it must be allowed to drj'^ for a con- siderable time _; after which a flrs may be kindled, and the furnace gradually heated for one or two days. The heat should then be raised to the highest degree of in- tensity, by which the hiiing will acquire the hardi:iess of free-stone, and afterwards be as durable as any other part of the furnace. LUXATION , signifies the^islo- catlon of any bone out of its natu- ral articulation, so as to impede or destroy its proper motion. The general symptoms of this complaint are, inability to move the injured limb 3 pain ; tension ; and defor- mity of tliC part aft'efted : it is also frequently attended willi inflam- mation and fever.
