Water is thirteen or fourteen times lighter than Quick-silver and by consequence thirteen or fourteen times rarer, and its Resistance is less than that of Quick-silver in the same Proportion, or thereabouts, as I have found by Experiments made with Pendulums.

Página 359 - that the Heat acquired by the Iron, was not communicated by " either of thofe Implements, as heat ; but produced in it by a " Motion, great enough ftrongly to agitate the Parts of fo fmall a " Body as the Piece of Iron, without being able to have the like " Effect upon fo much greater Mafles of Metal, as the Hammer " and the Anvil.

For if Salt of Tartar be mixed with Gunpowder , and that Mixture be warmed till it takes Fire, the Explofion will be more violent and quick than that of Gunpowder alone, which cannot proceed from any other Caufe than the Action of the Vapor of the Gunpowder upon the Salt of Tartar, whereby that Salt is rarified. The Explofion of Gunpowder arifes therefore from the violent Action whereby all the...
