OP DISTILLATION, AND THE APPARATUSES MADE USE OF. The apparatus for distilling, upon which many im- provements in France are founded, is that of M. Adam. In a furnace, situated in one corner of the distillery, is placed a still built into the masonry. The head is in the form of a dome, solidly fixed with the cucurbit. From the centre of this dome a tube ascends, as thick as a man's arm ; and this runs into the first vessel, placed on one side of the still, which is fixed upon strong joists. From this vessel issues a second tube, similar to the first, but in the form of an arch, which enters into an- other vessel, also resembling the first, which communi- cates with a third in the same manner. In this apparatus, thus simplified, there are several points to be considered In the first place, all the vessels fixed upon the joists are made in the form of an egg, and have their two ends placed vertically. Secondly, that the entering tubes, viz. those which proceed from the still to the first egg, and from the first to the second, &c. have their extremities in the bottom of each egg^ and there form something like the head of a garden or watering pot, pierced with several holes. Thirdly, the last of these eggs, when there are but three, and sometimes the two last, when there are four, are furnished with a cooler in their upper part ; and this is always filled with water while the distillation is going on. These vessels, with their refrigerators, are called condensers. Every distiller does not use condensers ; the majority 2*
