tubes the extremities of which are bent down into the liquid flowing through the still. The steam from the boiler passes up the tube h h into the hollow vessels c, c, and thence through the tubes d^ d, d into the smaller curved pipes e, e, e; at the extremities of which it pervades the liquid in its progress. If it should be deemed more advantageous to transmit the caloric from the steam through the metal, without allowing the steam to pass into the liquid, it may be done by closing the ex- tremities of the curved pipes e, e, e, and placing them in a horizontal position, with a small inclination, in order to allow the condensed steam to pass into the boiler. Here the spirit arising in one still might pass into an- other, and be again operated upon; and distillings of every degree and of various substances may be carried on in one continued operation at the same time and by one nic derate fire, which^ upon this principle, will suffice for
