1. Mix according to the source passage: Lime prepared on the great scale for the ordinary purposes of art is sufficiently pure for medicinal use; but for some pharmaceutical purposes it is required to be more completely burnt than is usually the case of that which is obtained from the kilns; and perhaps it is with this view that the above preparations have been ordered by the London College. — It may, however, be observed, that neither of the substances ordered affords lime in a state of absolute purity ; limestone frequently containing silex, alumina, magnesia, and marine shells; and a portion of phosphate of lime which is not de- composed by the fire. ‘To obtain perfectly pure lime, dis- solve white marble or clean oyster-shells in diluted muriatic acid, and to the filtered solution add solution of ammenia as long as any precipitate falls; then filter again, and decompose the muriate by a solution of pure carbonate of potassa: wash the precipitate, and expose it to violent heat in a platina crucible, till it cease to lose weight. The result is pure lime, fifty-six parts of which should be furnished for every 100 parts of pure white marble used.
