    POTASSjE carbonas purum. (Potassce Carbonas e Tartari Crystallis.) Take of White Bitartrate of Potash, two pounds; Sesquicarbonate of Ammonia, half an ounce; Distilled Water, three pints: Place the bitartrate of potash in an iron pot or crucible, and, constantly stirring it with an iron rod, expose it to a red heat until vapours cease to be evolved. Reduce the residuum to a coarse powder, and, having boiled it for twenty minutes with one quart of the water, filter through paper, washing the filter and its contents with the residual pint of water, in which the sesquicarbonate of ammonia has been first dissolved. The filtered solution is now to be evaporated to dryness, and, a low red heat being finally applied, the product is to be rapidly reduced to powder in a warm mortar, and enclosed in well- stopped bottles. POTASSiE CARBONATIS LIQUOR. (Potassce Carbonatis Aqua.) Take of Pure Carbonate of Potash, ten ounces; Distilled Water, one pint: Dissolve and filter.
