    tlalinemann. The ancients, it appears, Averc ac- quainted with this property in Lead, for according- to Plinj, the Greeiis and Romans improved tlie quality of their wines by immersing a plate of lead in them.* Wine, as a pharmaceutical agent, is employed to ex- tract several of the principles of vegetables, and to dissolve certain mineral bodies: as a solvent, how- ever, it is liable to many serious objections, as in- equality of streng th, and uncertainty of composition ; thus sound and perfectly fermented dry wine, as Sherri/, is frequently unable to dissolve iron, while tartarized antimony is instantly decomposed by every other. As a menstruum, to obtain an extract, it is quite inadmissible on account of the residuum which it leaves by evaporation. ViNUM Aloes. L. E. D. This solution contains all the virtues of the Aloes, and is more agreeable than the tincture. It is a warm stomachic in doses of fjj to f3ij, and a stimulating purgative when given from f§j to f§ij. ViNUM Ferri. L. D. When prepared according to the London College, each pint is stated to contain 22 grains of the red Oxide of Iron ; the strength how- ever must in every case depend upon the quantity of tartar contained in the wine. Very dry Sherry is frequently incapable of acting upon the iron until a small proportion of Cream of Tartar be added to it; would it not therefore be adviseable to direct at once a given portion of ferrum lartarizalum to be dissolved ■will precipitate the least quantity of Lead from wines in a very sensible- black precipitate. As Iron might be accidentally contained in the wine, the muriatic acid is added to prevent its precipitation. * Lead will not only correct tlie acidity of wines, but remove the ran- cidity of oils: a property which is well known to Painters, and which affords an expedient for making an inferior olive oil pass for good. 2o
