Unformatted text preview: a relatively large surface and extract some of the solute. The ethereal extract gradually increases in bulk, and the upper part of it is returned continuously by the system F to the flask E. Here the ether is again vapourised and recycled as above. Thus after a large number of cycles the solute will gradually accumulate in the ether in E and the solute can then be recovered by normal distillation or evaporation of the ethereal solution.
