EXPERIMENT VII.
- May 12. 76.* 1.1 SOme Spirit of Wine contain'd in a Glass Vessel, with some drops of Oyl of Tur∣pentine upon it, were briskly mov'd about, till the Receiver being exhausted, they stuck to several Bubbles which rose out of the Spirit of Wine, and were by them carri'd to the sides of the Vessel; where they were kept, except 2 Drops, which the Bubbles left behind upon the Surface of the Spirit; which, whilst the Receiver was exhausting, continued their Mo∣tion, but in a little time after, were wholly at rest. Yet upon a Re-ingress of Air, they for a little while renew'd their Motion again.
- The same Experiment being repeated with Spirit of Wine and Oyl of Turpentine, wholly freed from Air; there was neither any Ebulli∣tion, nor an appearance of Bubbles; yet the Drops of Oyl mov'd in Vacuo after the same Manner as in open Air.
- Hence it appears, that the Motion of the Parts of Oyl, depend not in a Dissolution in Vacuo; since all Dissolutions are company'd with a production of Bubbles.
