EXPERIMENT XLIII.
* 1.1HAving clos'd in our Receive a Viol of four Ounces fill'd with hot Water, which had been freed from Air by boiling, we pump'd out the Air, and observ'd, That upon the fourth Ex∣suction, it began to boil, as if it had been over a hot Fire, so that part of it ran over, and conti∣nu'd boiling in our Receiver. And what was more remarkable, was, that as often as the Air was let out of the Receiver into the Pump, the E∣bullition was again renew'd, the Fiery and Agi∣tated Parts of the Liquor, upon a Removal of the Air's Pressure, having more Liberty to expand themselves. And that the Phaenomenon was pro∣moted by the Removal of that Pressure, we may guess, because the Ebullition was only in the Top of the Liquor; and that it was renew'd upon a Removal of that Pressure. But especially, be∣cause Sallet-Oyl, whose Parts adhere, by Reason of their Clamminess, would not ferment; yet Oyl of Turpentine, or Wine would, whose Parts are not so tenacious; the former rising five times its Height, and near four Parts of the latter running over into the Receiver.
