The still a, which, as well as the stUl A, isfilled with wine, acts as a steam boiler. Thelow wine vapours evolved come, when theyhave arrived in the rectifiers, in contact with anuninterrupted stream of wine, whereby de-phlegmation is effected; the vapour, thus en-riched in alcohol, becomes stronger in thevessel (d), and thus arrives at the coolingapparatus (f). In order that a real rectifica-tion should take place in the rectificators thestream of wine should be heated to a certaintemperature, which is imparted to it by theheating of the condensed water. The steamfrom the still a is carried by means of the pipe(z) to the bottom of the still A. Both stills are heated by the fire of thesame furnace. By means of the tube b theliquid contained in the still A can be run into thestill a. The first rectificator (b) containing a STILL 1567

The largerdiscs, perforated in the manner of sieves,are placed with their concave surfaces up-wards. In consequence of this arrangement thevapours ascending from the stills meet withlarge surfaces moistened with wine, which,moreover, trickles downward in the mannerof a cascade from the discs, and comes, there- fore, into very intimate contact with thevapours. The second rectificator (c) is fittedwith six compartments; in the centre of eachof the partition walls (iron or copper plates)a hole is cut, and over this hole, by means ofa vertical bar, is fastened an inverted cup,which nearly reaches to the bottom of thecompartment wherein it is placed. As a por-tion of the vapours are condensed in thesecompartments, the vapours are necessarilyforced through a layer of low wine, and haveto overc
