lowest place, and expels the warm liquor which server to charge the still or the egg. This construction has another advantage, as the alcoholic vapours that escape the tun can find no other issue but through the tube, which carries them into the egg. The whole knowledge of distilling apparatus consists in the perfect understanding of the application of heat, of vaporization, and of condensation. For the purpose of acquainting the distiller more perfectly with his calling, all the various apparatuses and improved processes will be given, as far as thought strictly practical and useful. It now remains to give a description of the different systems on which the most remarkable apparatuses of dis- tillation have been constructed. These systems may be reduced to four principal and distinctive : — 1. Distillation by the simple apparatus. 2. Distillation by the wine- warming condensing apparatus. 3. Distillation by steam and by rectifiers. 4. Continuous distillation. The three first will be described elsewhere in this work ; the fourth will now be considered^ constituting what is ternied

CONTINUOUS DISTILLATION.

The continuous apparatus, which is here to be de- scribed, fig. 2, has undergone many improvements, and

is now presented in its most perfect state. This apparatus is composed 1st. Of one still, and sometimes of two. 2d. Of a distilling column. 8d. Of a rectifier. 4th. Of a wine-warming condenser.
