    Attention has been drawn to the contamination of drinking waters by the infiltration of sewage; and several wells, previously esteemed for the brilliant and cool taste of the water, have since been abandoned as being totally unfit for drinking or culinary purposes. AQUA DESTILLATA. Purest water distilled through a block-tin worm, rejecting the first portion that comes over, and distilling only three-fourths of the whole. Distilled water has, when freshly drawn, an unpleasant odour, which is removed by passing it through a charcoal filter, or by exposing it to air, but Carbonic Acid is in that case absorbed by it, and Sub- acetate of Lead will then render it milky. If water is distilled through leaden pipes, it becomes impregnated with lead; the same is the case with natural soft water passing through leaden pipes. The royal buckhounds were poisoned at Ascot from this cause. Zinc wire reaching the whole length of the column of water so impregnated displaces the Lead. Water containing Sulphate of Lime seems less likely to become impregnated with Lead than that containing the Chlorides. The Waters of the British Pharmacopoeia, which are all distilled, except Aq. Camphorte and Aq. Chloroformi, are as follow; the formulas are given under the names of the substances from which they are prepared. AQUA AKETHI. From the dried fruit. Dose, i to 1 oz AQUA AURANTII FLORIS. From the flowers. Imported. | to 1 oz. AQUA CAMPHOR2E. (Formerly Mistura Camphorso.) 1 to 2 oz. AQUA CARUI. From the dried fruit. 1 to 2 oz. AQUA CHLOROFORMI. 1 to 2 oz AQUA CINNAMOMI. From the hark. 1 to 1 oz AQUA DESTILLATA. AQUA FCENICULI. From the dried fruit. 1 to 2 oz AQUA LAUROCER A SI. From fresh leaves. 5 to 30 min AQUA MENTH2E PIPERITA. With oil and distilled. 1 to 2 oz AQUA MENTHA VIRIDIS. With oil and distilled. 1 to 2 oz AQUA PIMENTiE. From the dried unripe berries. 1 to 2 oz. AQUA ROSiE. From the fresh petals. 7 to 1 oz AQUA SAMBUCI. From the fresh flowers. J to 1 oz! It was thought proper in former Pharmacopoeias to add spirit to the several distilled Medicated Waters, to preserve them from change but Mr. Warrington has shown, by experiment, that this is an error. ' He kept bottles of Dill and Anise Waters with and without spirit for two years, and found that those without spirit kept well, whilst those with spirit had become acidified by the spirit changing into Acetic Acid. Not Official. ARAROBA. Syn. Goa Powder, Chrysarobine, Poh di Bahia. Is obtained from a tree of the order Leguminoste, growing in the province of Jiahia ; it is found in the clefts of the wood. It contains about eighty per cent of Chrysophanic Acid. 1 F 2
