Page 101 - I let up some solution of liver of sulphur to absorb the dephlogisticated air, after which only a small bubble of air remained unabsorbed, which certainly was not more than -j-^ of the bulk of the phlogisticated air let up into the tube ; so that if there is any part of the phlogisticated air of our atmosphere which differs from the rest and cannot be reduced to nitrous acid, we may safely conclude that it is not more than T^ part of the whole.
Page 93 - ... times that quantity of common air, and the burnt air made to pass through a glass cylinder eight feet long and three-quarters of an inch in diameter, in order to deposit the dew. The two airs were conveyed slowly into this cylinder by separate copper pipes, passing through a brass plate which stopped up the end of the cylinder...
Page 95 - In order to examine the nature of the matter condensed on firing a mixture of dephlogisticated and inflammable air, I took a glass globe, holding 8800 grain measures, furnished with a brass cock and an apparatus for firing air by electricity. This globe was well exhausted by an airpump, and then filled with a mixture of inflammable and dephlogisticated air, by shutting the cock, fastening a bent glass tube to its mouth, and letting up the end of it into a glass jar inverted into water, and containing...
Page 121 - When three combinations are obtained, we may expect one to be a binary and the other two ternary. 4th. When four combinations are observed, we should expect one binary, two ternary, and one quaternary, &c.
Page 120 - Chemical analysis and synthesis go no farther than to the separation of particles one from another, and to their reunion. No new creation or destruction of matter is within the reach of chemical agency.
Page 88 - I presently found that, by means of this lens, air was expelled from it very readily. Having got about three or four times as much as the bulk of my materials, I admitted water to it, and found that it was not imbibed by it. But what surprised me more than I can express was that a candle burned in this air with a remarkably vigorous flame...
Page 109 - ... les chimistes ont fait du phlogistique un principe vague, qui n'est point rigoureusement défini, et qui, en conséquence, s'adapte à toutes les explications dans lesquelles on veut le faire entrer...
Page 121 - When only one combination of two bodies can be obtained, it must be presumed to be a binary one, unless some cause appear to the contrary.
Page 121 - ... 1 atom of A + 1 atom of B = 1 atom of C, binary. 1 atom of A + 2 atoms of B = 1 atom of D, ternary.
Page 117 - The ultimate particles of all simple bodies are atoms incapable of further division. These atoms (at least viewed along with their atmospheres of heat) are all spheres, and are each of them possessed of particular weights, which may be denoted by numbers.
