The thing, in that mode, I do not know to be possible. As I meddle with no theory, I do not absolutely assert the impracticability of such a representation.

Pagina 203 - ... seems to imagine that he can arrange the different members of a great society, with as much ease as the hand arranges the different pieces upon a chess-board: he does not consider that the pieces upon the chessboard have no other principle of motion besides that which the hand impresses upon them; but that, in the great chess-board of human society, every single piece has a principle of motion of its own, altogether different from that which the legislature might choose to impress upon it.

Pagina 65 - 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 Royal Society.
