Page 52 - ... fluid, which, insinuating itself between the particles of bodies, separates them from each other; and, even allowing the existence of this fluid to be hypothetical, we shall see in the sequel, that it explains the phenomena of nature in a very satisfactory manner.
Page 196 - After giving the details of his analysis of sugar and of the products of fermentation Lavoisier continues : — " The effect of the vinous fermentation upon sugar is thus reduced to the mere separation of its elements into two portions ; one part is oxygenated at the expense of the other, so as to form carbonic acid ; while the other part, being disoxygenated in favour of the latter, is converted into the combustible substance called alkohol ; therefore, if it were possible to re-unite alkohol and...
Page xxxv - The method, too, by which we conduct our reasonings is as absurd; we abuse words which we do not understand, and call this the art of reasoning. When matters have been brought this length, when errors have been thus accumulated, there is but one remedy by which order can be restored to the faculty of thinking; this is, to forget all that we have learned, to trace back our ideas to their source, to follow the train in which they rise, and, as my Lord Bacon says, to frame the human understanding anew.

Page 87 - Take a piece of fine iron wire, twifted into a fpiral, BC, Plate IV. Fig. 17. ; fix one of its extremities B into the cork A, adapted to the neck of the bottle DEFG, and fix to the other extremity of the wire C, a fmall morfel of tinder. Matters being thus prepared, fill the bottle DEFG with air deprived of its mephitic part; then light the tinder, and introduce it quickly, with the wire upon which it is fixed, into the bottle, which you flop up with the cork A, as is fhown in the figure 17.
Page 254 - ... Elements LAVOISIER treats of the formation of Neutral Salts, and throws out new and important views, relating to the constitution of chemical compounds. Speaking of the influence of Light as a chemical agent, he adverts to its singular action upon the vegetable kingdom, and supposes that it combines with certain parts of" vegetables, and that the green of their leaves, and the various colours of their flowers, are chiefly owing to this combination.
Page 486 - As it is apt to foften by heat, we muft furround all the junctures with flips of wet bladder applied over the luting, and fixed on by pack-thread tied round both above and below the joint ; the bladder, and confequently the lute below, muft be farther fecured by a number of turns of pack-thread all over it. By thefe precautions, we are free from every danger of accident ; and the j-unctures fecured in this manner may be confidered, in experiments, as hermetically fealed.

Page 487 - These are applied while still moist, and very speedily dry and acquire considerable hardness. These fillets are usually applied likewise over junctures luted together with wax and rosin. Before applying a lute all the junctures of the vessels must be accurately and firmly fitted to each other so as not to admit of being moved. If the beak of a retort is to be luted to the neck of a receiver, they ought to fit pretty accurately, otherwise we must fix them by introducing short pieces of soft wood or...
