Seite 88 - April, 1783, in which he reasons on the experiment of burning the two gases in a close vessel, and draws the conclusion, " that water is composed of dephlogisticated air and phlogiston, deprived of part of their latent heat."* The letter was received by Dr.
Seite 87 - about one-fifth of the common air, and nearly all the inflammable air, lose their elasticity, and are condensed into the dew which lines the glass.
Seite 87 - Priestley's 5th volume,* gave rise to this inquiry, at least in England ; Mr. Cavendish expressly refers to it, as having set him upon making his experiments. — (Phil. Trans. 1784, p. 126.) The experiment of Mr. Warltire consisted in firing, by electricity, a mixture of inflammable and common air in a close vessel, and two things were said to be observed : first, a sensible loss of weight ; second, a.

Seite 87 - Priestley's 5th volume. Mr. Cavendish himself could find no loss of weight, and he says that Dr. Priestley had also tried the experiment, and found none. But Mr. Cavendish found there was always a dewy deposit, without any sooty matter. The result of many trials was, that common air and inflammable air being...
Seite 89 - Cavendish leaves it uncertain, whether or not he meant by phlogiston simply inflammable air, and he inclines rather to call inflammable air, water united to phlogiston. Mr. Watt says expressly, even in his later paper (of November 1783), and in a passage not to be found in the letter of April 1783, that he thinks that inflammable air contains a small quantity of water, and much elementary heat. It must be admitted that such expressions as these on the part of both of those great men, betoken a certain...
Seite 87 - Lavoisier, as well as of the conclusion drawn from them, that dephlogisticated air is only water deprived of its phlogiston; but, at that time, so far was M. Lavoisier from thinking any such opinion warranted, that till he was prevailed upon to repeat the experiment himself, he found some difficulty in believing that nearly the whole of the two airs could be converted into water.
