Salts, with the bafis of alumine, or the earth of pure clay, are but rarely found in any mineral waters. Aluminous earth Las been found in folution with the three acids, that ar« moft commonly joined to the two preceding earths, the carbonic, fulphuric, and muriatic, but none requires particular notice except the 12.—Sulpbat of Alumine^ or Common Alum, This fait is foluble in its own weight of boil- ing water, but requires a much larger propor- tion of cold water. It readily forms cryftals, permanent in the air, and has an acid and very aftringent tafte. Alum poffeffes naturally an excefs of acid, which is neceffary to the con- ftitution of this fait, and therefore it fhews with different re-agents the fame appearances ;^s an uncombined acid. Alum is but rarely contained in mineral waters, and is generally found alTociated with fulphat of iron. It Is
