the water which passes in the state of steam out of the still A is to be replaced, and as it is indispensable that this water should be very hot, it is drawn from the worm- tub E through 00 0] before it enters the still it passes through G, where the matter is boiling hot. Cock No. 4 regulates the quantity of water which is to be introduced. When all the matter has been pumped out, the process is continued for about a quarter of an hour, for the pur- pose of exhausting the matter left in the column. The fire is then drawn off 3 cock No. 1, fixed on the tube a a a, is opened, as also cock No. 3, which is fixed to the tube K on the lower part of the column. The next day the ope- rations are recommenced in the same way. The column and the condensers are left filled with matter. There is another system of continuous distillation which will here be described ; it possesses the advantage that it can be applied (the distilling column) to the neck of the A, double still, having a copper partition in the middle, which divides it from top to bottom ) there is a hole at the lower part of the partition, so as to establish a communication between the two stills. B, first distilling column. C, second distilling column. Each of these columns contain an evaporator in the form of a double vice of Archimedes. D is a common capital or head belonging to the first column. E, I capital or condenser, for the purpose of makings strong spirits. still. See fig. 4, on the opposite page.
