![the liquor, and concentrate by boiling till a pellicle floats on the surface, and set it aside that crystals may be formed. The liquor being poured off, dry these, and again evaporate the liquor that crystals may be produced. Physical Properties.—A solid, white salt, crystalline, but gene- rally met with in the form of a granular powder; the crystals are small right rhombic prisms. It is inodorous, and has a cooling saline taste. Sp. gr. L556. Chemical Properties.—It is composed of 1 eq. of potassa, and 1 of tartaric acid, (KO, C8H4010 ;) it attracts moisture in a damp at- mosphere, but does not deliquesce ; exposed to heat it is decomposed, and converted into a compound of carbonate of potash and charcoal. It is soluble in an equal weight of cold water, whence the name solu- ble tartar is applied to it ; it is likewise soluble in alcohol. Adulterations.—This salt is not unfrequently adulterated with the bitartrate, which may be known by its not being soluble in its own weight of water at 50°. It also sometimes contains carbonate or sul- phate of potash or chloride of potassium ; any of which may be detect- ed by the precipitates occasioned in it by chloride of barium or ace- tate of lead not being soluble in dilute nitric acid ; Lond. Ph. Therapeutical Effects.—A mild but efficient purgative, not much employed in the present day. By accelerating the operation of the resinous purgatives, it corrects their griping properties. Dose and Mode of Administration.—3ij. to 3*. in solution. Incompatibles.—All acids, and most acidulous salts ; lime water ; chloride of calcium ; nitrate of silver; and acetate oflead. Pruna, L. E. [Prunum, U. S.] Prunus domestica, fructus sic- catus, D. Prunes. The dried fruit of Prunus domestica. The plum tree, originally a native of Syria, is now cultivated extensively in the temperate regions of Europe, and in the British Isles ; it be- longs to the Natural family Rosacea (Drupacece, Lindley,) and to the Linnaean class and order Icosandria Monogynia. The fruit dried in the sun constitutes prunes; they are imported principally from Bourdeaux. Prunes are mildly laxative, and are sometimes added to infusion of senna to conceal its nauseous taste. They enter into the composition of the electuary of senna of the pharmacopoeias. Rhamni baccje, E. Rhamnus, L. Rhamnus catharticus bacc.e, D. Buckthorn berries. Fruit of Rhamnus catharticus. An indige- nous shrub, belonging to the Natural family Rhamnacem, and to the Linnaean class and order Pentandria Monogynia, Botanical Characters.—Stems about ten feet high, branching spiny: Leaves, ovate, sharply serrated; Flowers small, yellowish-green dioecious Fruit, a berry. ° ' ' Physical Properties.—The berries are about the size of peas, black, shining, four-seeded, with a green juicy parenchyma ; they have an acrid, nauseous taste, and when bruised, emit a faint unpleasant odour. I he juice is preserved in the form of syrup. Chemical Properties.—The juice consists of a peculiar colouring matter, acetic acid, mucilage, sugar, and nitrogenoua matter The](https://iiif.wellcomecollection.org/image/b21143602_0114.jp2/full/800%2C/0/default.jpg)
