"O boiler through the tube into the xcorm (3), and in passin^ through the worm, becofhe condensed by the cold. The I'efrigerator, or worm-tub (4), must be kept full, by a con stant stream ofcold water,or else the water at the bottom Avill be cold, while that of the surface will be very hot. The cold water is supplied at 6, and escapes at 6. With respect to thejjractical jiart of distilling, we sh.all observe that the heat should, in all cases, be as gentle and uniform as jiossihle. Accidents may be effectually pre vented by distilling spirits in a water bath, which, if suf ficiently large, Avill jierform the o2ieration with all the dis patch requisite for the most extensh'e business. The vessel in which the distillation is effected ought to be im mersed m another filled Avith Avater up to the neck. The process will thus b^ managed as expeditiously as if the A'essel were placed over an ojAen fire, and Avithout the ap prehension of being disapjiointed by having your sjjirits burned; nor will it be necessary at any time to raise the Avater in the bath to a boiling heat. By looking at the en graving ofthe still, you will see Avhat we mean. The inner boiler or concurhit, marked (2), is the vessel in Avhich the liquids to be distilled are put, and the outer boiler,or bath (A) is the vessel that shoAild,be filled Avith water. This is sometimes called a Bain Marie. The cover ofthe inner boiler must be well luted,that is, closed completely, to prevent evaporation. Take a lute, made ofequal jArojAortions offiour, whitening and salt, mix ed together with the blade of a knife, and. diluted Avith water; spread this on a jAiece of rag, and close all the crevices. The object of distillation is to separate one substance from others with which it may be mixed.
