Page cxxv - Are we not, then, authorised to conclude, that water is composed of dephlogisticated air and phlogiston, deprived of part of their latent or elementary heat; that dephlogisticated or pure air is composed of water deprived of its phlogiston, and united to elementary heat and light...
Page 237 - En 1593, le bruit courut que les dents étant tombées à un enfant de Silésie, âgé de sept ans, il lui en était venu une d'or à la place d'une de ses grosses dents. Horstius, professeur en médecine dans l'université de Helmstad, écrivit en 1595 l'histoire de cette dent, et prétendit qu'elle était en partie naturelle, en partie miraculeuse, et qu'elle avait été envoyée de Dieu à cet enfant, pour consoler les chrétiens affligés par les Turcs.

Page 227 - ... that dephlogisticated or pure air is composed of water deprived of its phlogiston, and united to elementary heat and light; and that the latter are contained in it in a latent state, so as not to be sensible to the thermometer or to the eye; and if light be only a modification of heat, or a circumstance attending it, or a component part of the inflammable air, then pure or dephlogisticated air is composed of...

Page 256 - Lavoisier, that Mr. Cavendish had drawn his conclusion before April, 1783, although in one of the additions to that paper, reference is made to Mr. Watt's theory. As great obscurity hangs over the material question at what time Mr. Cavendish first drew the conclusion from his experiment, it may be as well to examine what that great man's habit was in communicating his discoveries to the Eoyal Society.
Page lxx - I think, we must allow that dephlogisticated air is in reality nothing but dephlogisticated water, or water deprived of its phlogiston; or, in other words, that water consists of dephlogisticated air united to phlogiston; and that inflammable air is either pure phlogiston, as Dr.
Page 129 - ... 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.
