    Tickell's Chemical Medicine. NOW KNOW YE, that in compliance with the said proviso, I, the said William Ticked, do hereby declare that my said Invention is described in manner following (that is to say):— Take of highly rectified spirit of wine six quarts, of concentrated oil of vitriol ten pounds; pour the spirit of wine into a receiver, to which the oil 5 of vitriol is to be added gradually, and when cold the mixture is to be put into a bottle with a glass stopple, in which it is to remain ten days or a fortnight. Take three quarts of this mixture and put it into a large retort, lute on a capacious receiver, distil with a moderate fire, but sufficient to keep the mixture in a boiling state for the space of twelve hours; a pin 10 should be passed through the luting occasionally to discharge over-rarified air. The following morning three quarts more of the same mixture are to be added to what remains in the retort; the receiver is again to be carefully luted on, and the distillation again continued for the space of twelve hours. On the third morning add to the mixture in the retort twelve ounces of 15 highly rectified spirit of wine, in which half an ounce of the genuine oil of juniper or of camphire has been previously dissolved; lute the receiver, and again continue the distillation for twelve hours. On the fourth morning the distillation is again to be commenced and continued for the same space of time, but the fire is to be regulated with more caution, otherwise a bursting 20 of the glass or an ebullition will frustrate the operation. The spirit which is the produce of these several distillations is now to be poured into a seperating funnel, and the crude phlegm seperated from it, when it is to be edulcorated by the repeated effusion of cold spring water. The receiver is now to be again luted on, and the distillation continued with a moderate fire for the 25 space of twenty-four hours, by which final operation the oleum polychrestum verum will be obtained, which is likewise to be seperated from its acid; half an ounce of this pure oil is to be added to thirty-one ounces and half of the pure spirit, and thus is prepared the genuine anodyne oethereal spirit, which may either remain in its limpid state, or be coloured by any of the 3D resinous woods, as may best please the operator. In witness whereof, I, the said Will. Tickell, have hereunto set my hand and seal, this Twenty-first day of August, 1786. ‘ WILLIAM TICKELL. (l.s.) ~ f success of the operation will depend on the skill of the operator, 35 on an exact regulation of heat, and a minute observance of the rules laid down for conducting the process.
