the head, become condensed, and then trickle down the inside of the vessel and descend into the vat. By the application of this apparatus a certain propor- tion of the alcohol, which has been hitherto suffered to escape with the non-condensable gases in the form of steam, will be condensed and returned into the liquor while the non-condensable parts will be carried off through a pipe. The cut (fig. 11) represents this improved apparatus, the vat and the cold-water reservoir being shown in a is the vat containing the fermenting liquor, in the top of which is an aperture communicating with the interior of the conical-formed vessel h ) the lower part of this vessel is made cylindrical, and passes through a circular plate, on which the supporters rest, c is the re- servoir of cold water surrounding the conical vessel, which may be supplied by a stream of running water, c^ is a worm or pipe communicating with the interior of the ves- sel 5, and, passing off through the side of the reservoir, descends into another vessel of water, e. / is a small pipe which proceeds from the lower part of the vessel 5, and descends through the fermenting liquor nearly to the bot- tom of the vat. The gas and alcohol rising from the liquor in the vat into the conical head 5, and coming in contact with the cold sides of the vessel, produces a con- densation of the alcohol, which runs down the side of the cone into the circular channel g at its base, from whence the alcohol passes by the pipe / into the vat below ; while the non-condensable gases pass out through the worm-pipe d, and finally escape by bubbling up through the water into the vessel e. section,
