 Bodies, as Iron, Tin, Copper: that Heat and Lidit are two inseparable Effects of this Dissolution, as Heat and Ebullition are of those Dissolutions of Tin, and Copper: that Flame is a Dissolution of Smoak, which consists of combustible Particles, carried upward by the Heat of rarified Air: and that Ashes are a Part of the Body not dissoluble by the Air.

Of this Sort, they have made Experiments, to find the lasting of the burning of a Candle, Lamp, or Coals, in a cubic Foot of common, rarified, and condens'd Air: to exhibit the sudden Extinction of Candles, Lamps, and lighted Coals, when they arc put into satiated Air: to shew the speedy Extinction of kindled Charcoals, by blowing on them with Bellows, that Air which had before been satiated with burning: to shew that the greatest and most lasting Heat, without a Supply of fresh Air, is unable to burn Wood, Sulphur, and most other combustible Matters: to find the comparative Heat of all Kinds of Fires, and Flames of several Materials, as of Sulphur, Camphire, Spirit of Wine, Oyl, Wood, Coal, Seacoal, Iron: to find at what Degree of Heat, Lead, Tin, Silver, Brass, Copper, Gold will melt.

Experiments of the Transparency, and Refractedness of Flames: of discerning the Strength of several Kinds of Gunpowder, Pulvis Fulminans, Aurum Fulminans: of Gunpowder in the exhausting Engine: of bending Springs by the Help of Gunpowder: of melting Copper immediately, by the Help of a Flux-powder: of the recoyling of Guns.

Experiments of Candles, and Coals, extinguish'd by the Damps of a deep Well: of the burning of Lamps under Water: of burning Spirit of Wine and Camphire together, and the Diversity of their Flames: of Rh
