Take of Rectified spirit, Sulphuric acid, of each, by weighty a pound and a half; Pour the spirit into a glass retort, and gradually add the acid to it, frequently shaking them, and taking care that the temperature does not exceed 120®, until they are mixed. Then place the retort cautiously in a sand-bath, previously heated to 200°, so that the liquor may boil as quickly as possible, and the aether may pass over into a tubulated receiver, to which another receiver is adapted, and kept cold 1^ ice or water. Let the liquor distil, until a heavier fluid begins to pass over and to wpear under the aether at the bottom of the receiver. To the fiquor which remains in the retort again pour twelve ounces of rectified spirit, that aether may distil in the same manner.
