TITLE XXV. Of the Air in reference to Fermentation.
* 1.1RAisins being enclos'd in an exhausted Bolt∣head half full of Water, and set on a di∣gestive Furnace, presently began to ferment; and swimming upon the Liquor afforded Bubbles, which were gradually fewer; and at last a Sedi∣ment appeard in the Bottom. The Top of the Bottle being accidentally broke, the External Air rush'd in with some Noise, and the Surface of the Liquor was cover'd with Froth like Bottle Drink, and I thought I perceiv'd a visible Fume come out of the Glass, which had a Languid Smell. The Liquor had a high Tincture of the Raisins, and was of a better Consistence than that of Water.
