Lipome

See Naevus.

Lipopsychia

Lippitudo

(From lippus, blear eyed). See Eri-hora and Xerophthalmia. Celsus means by it an ophthalmia.

Liquefactio

Melting. The fluidity of a body when exposed to heat, probably from the combination of caloric. Though we know bodies permanently aeriform, we know none permanently fluid, except alcohol and ether; and those are apparently such, because they have not been exposed to the requisite degree of cold. It is not necessary to liquefaction that the body wets; for this effect is owing to the greater attraction of the fluid particles to the body than to each other. Quicksilver is fluid, but does not wet. Melted lead does not adhere to a polished iron immersed in it.

Liquidambar

(From liquidus, and ambar). Sty-rax liquida, acer virginianum odoratum, liquidambar stiraciflua Lin. Sp. Pl. 1418, is a resinous juice, of a yellow colour, inclining to red; about the consistence of turpentine; by age hardening into a brittle resin. It is moderately warm and pungent, but rarely met with genuine, and chiefly used as a perfume. See Lewis's Materia Medica.

Liquiritia

(From liquor, juice; or the Welch term elikoris). See Glycyrrhiza.

Lithagogus

(From Lithagogus 4739 a stone, and to bring away). An epithet for a medicine that expels the stone.

Lithargyrum

(From Lithargyrum 4741 and silver). Litharge; lithargyrum auri, almakanda, almakarb, chrysitis, chrysitis spodos; cycima; calci-teosa, argyritis; cathmia. Litharge was usually prepared from the lead employed in refining silver; and it was of a deep yellow, or of a whitish colour, according to the different bodies mixed with it, or according to the different degrees of heat to which it was exposed. If its colour is dark it is called litharge of gold, alatam; if light, of silver, almar-carida. This method, however, is not sufficient for the supply; and it is often prepared by melting oxidized lead by a hasty fire. There are a very great variety of medical compositions, of which litharge, or some of its preparations, make the principal, and alwavs a material, ingredient,

Lithargyri Acetati Aqua

(see Plumbum,) is made by dissolving two pounds, four ounces of litharge in a gallon of distilled vinegar, by boiling to six pints.

Lithargvri acetati cremor. See Plumbum.
