In other words, the phlegm orimpure raw alcohol is only raised to such a tem-perature in the first column as to drive off the veryvolatile constituents such as the ethers. Thesetherefore pass off at the top of the first columninto the condenser C, the retrogradation or con-densed alcohol being returned to A, while theboiling phlegm taken from the middle of thecolumn and still containing the aldehydes, oils,etc., is conducted by a pipe E to the second columnB wherein the last runnings or amy lie oils, etc., areseparated from the purified spirits. The vapors in this column are carried to thecondensers D and F and from there to a refrigeratorG. The fusel oils are extracted from the platesslightly below the center of the column and arecarried to an oil concentrating apparatus H. In the most complete forms of apparatus usedto-day, there is a variation of
