ishould be made of copper, and is filled with wash or other liquid intended for subsequent distillation, by means of the pipe and funnel. This vessel should at least contain two charges for the upper compartment of the still. The outer vessel n n may be made of wood, and must be charged with water circumscribing the inner vessel. When the vessel is at- tached to other stills, the outer vessel n n may be dis- pensed with, and the pipe o o attached, which must com- municate with another condenser. The vapour passing from the still through the pipe /, as above described, pro- ceeds to the spiral condensing pipe^, which passes several times round the vessel I, and the vapour being cooled and condensed in its progress, finally collects in the form of spirits, and is drawn ofi" through the pipe o] q is a pipe inserted into the head of the vessel I, with a light valve opening upward, for admitting any vapour into the con- denser^, which might arise from Z; but this at the same time prevents the passage of any vapour from the still through the pipe f, A waste-pipe r is attached to the cistern n, to carry ofi* the surplus water. The parts of this apparatus claimed as an improvement by a gentle- man in London are a vessel to contain wash or other liquid in the progress of distilling, surrounded by a cavity for condensing the water from the still. The apparatus shown at h and s are glass vessels containing a number of graduated bubbles of known gravity, which being put into a glass vessel, into which a portion of the spirit passes from the still according to the number of bubbles afloat, denote the levity of the spirit by their colour or shape.
