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 partitio
