V) Vi yj ^y which means the inside may be seen, and the hand introduced in every part of the interior, c, rectifier, placed on the top of the column, in which the low wines, returning from the condenser at the distiller's leisure, are rectified by^the steam of water ascending from the column; the residue of the rectifier leaves the tube q ^, and runs into the boiler A. D, wash-warming condenser; the conduits of which, in- tended to receive the steam, are of a peculiar form, pre- senting a large condensing surface. The matter to be distilled is constantly introduced into it by means of a pump h, through a funnel h li ; the vapours arise from the column, are condensed, and heat this matter to 80°. The products of condensation are divided by the stop- cocks 7 and 8, which may be opened to send back into the rectifier those that do not possess the requisite strength, ii u serves to stir the matter in the condenser, to prevent the heavy part from settling at the bottom. E is a common refrigerator immersed in water. F is a probe, into which the produce of distillation is received. In the middle branch (/, covered with a glass bell, an hydrometer and thermometer are placed; e/ is a branch formed by a glass tube ; the products of distil- lation are seen running through the small tube e ; they run through /into the vessels intended to receive them. G is a vessel into which the spent-wash falls ; it comes in through ^, and runs out through m. This vessel fills the functions of an hydraulic safety-valve. H is a vessel with a plunging-tub; in case (which is not at all likely to happen) the matter in distillation should ascend into the column, it could not proceed to the con-
