n, as are also all the fine and skillful proportions of parts. Ornamented architraves are from the land of the Nile. Figures for columns, resembling the Atlantes and Caryatides of the Greeks, are found in old Egypt. 2. (Printing.) A perpendicular set of type or printed lines; usually said of matter separated from another set or bounded by a vertical rule or line. 3. (Distilling.) A vessel containing a vertical series of chambers used in stills for continuous distillation; such as Coffey's, in which the two columns are known as the analyzer and the rectifier. In Fig. 1392, it consists of a series of chambers placed one above the other, the lower one communicating with the vessel. Steam is admitted, and passes up through the pipes into the chambers, being compelled, by means of hoods, to descend in its passage, and enter the chambers beneath the surface of the liquid contained therein. The chambers are partially filled from above with the liquid to be distilled, the pipes d

still, and proceed with the operation until the required strength is attained. Dorn's still, yet employed in Germany, was one of the earliest invented for this purpose. Of the improvements on this, Derosne's is generally used in France, while Coffey's (Fig. 5814) is preferred in England. In this the saccharine solution, or wash, is pumped from the wash-charger a through the pipe b into the worm-tube, which passes from top to bottom of the rectifier c; in circulating through this tube its tet merely circulates around the upper convolutions of the washpipe, the low temperature of which condenses the spirit, which, collecting on a shelf flows off by a tube into the finished-spirit condenser, and is finally conveyed to the receiver. Coffey's still. In order to economize beat, the water-supply pipe of the boiler is of spiral form, and is immersed in a trough which receives the boiling-hot spent wash. Cellier Blumenthal's apparatus, improved by Derosne (Fig. 5815), consists o
