* 1.1HAving suspended a lighted piece of Match, together with a Bladder, to try whether the Smoak would hinder the Distention of the Bladder, as also whether the Light of the Match would be put out by it's own Smoak; I ob∣serv'd, that it afforded the same Phaenomena men∣tion'd in the foregoing Experiment, except that after Successive Re-admissions of the Air, it be∣ing
excluded for some time, the Fire was totally extinguish'd.
Besides which, the following Phaenomena were to be observ'd: First, That upon the turning of the Stop-Cock, the Cavity seem'd immediately darken'd, as if it proceeded from a Change of the Position of the Parts of the Smoak. Second∣ly, That a kind of Halo, consisting of some Ex∣halations hover'd about the Flame. And Lastly, It was observ'd, that the Fumes did not in the least obstruct the Distension of the Bladder.
Having try'd the Former Experiment with a lighted Match, in a small Receiver, I found, that the Fire was quite extinguish'd with it's own Smoak, before the Cover could be cemented on, except the overplus of Smoak was successively pump'd out, and a Supply of Fresh Air was let in at the Stop-Cock; which Method would con∣tribute to the Preserving of it.
The Reason of the afore∣mention'd Effect.
