    of sulphate of potash. Let it evaporate on a stove and crystal- lize. Should this deposit, which resembles salt, have the hard and acrid taste of alum, the proof is positive. K) By lead.—Lead, or some other metal, is often found in sweet wines, sometimes also in other wines, and is indeed a slow poison, worse than any other adulteration.—A nice taste will detect metallic poison in wine, the sweetness of which is dis- agreeable. Dilute sulphuret of lime in water, and drop some of it into a glass of wine—if it turns brown or black, it contains metallic poison. Suspend a bit of polished zinc in the wine— particles of lead will adhere to it, if contained in the wine. Dis- solve Glauber Salts in lukewarm water till it becomes saturated, let it cool, then pour into a tumbler half filled with wine, as much of it as will fill the tumbler, let it stand over night, and there will remain a white sediment from the lead. If you put into a glass of wine a few drops of sulphuric acid, and the wine becomes turbid and leaves a white sediment, it contains poison. i) By corrosive sublimate.—If you put a few drops of spirits of Sal Ammoniac into a teaspoonful of water, and throw this mixture into a glass of wine and it leaves the least sediment, the wine contains corrosive sublimate. Try this same wine thus: Put a gold coin on a piece of zinc, put both into a split made in a small stick and hold the stick in a large tumbler full of wine. Should a gray dust immediately appear on the coin, there is cor- rosive sublimate in the wine. k) By arsenic.—If you dissolve lime in water till the latter becomes saturated, then pour off what is clear into a clean tum- bler, and drop some wine into it, if the wine occasions white clouds, it is likely that it contains arsenic. To convince yourself still more fully, dissolve sugar of lead in Aquafortis, pour a wineglassful of this solution into a bottle of wine into which a little salt of hartshorn has been previously put, and stir it. The next day pour off what is clear, and with the turbid part wash the sediment well out, and strain it through blotting paper, till the liquid has passed through ; then after the sediment has been
