หน้า 31 - Have not the small particles of bodies certain powers, virtues, or forces, by which they act at a distance, not only upon the rays of light for reflecting, refracting, and inflecting them, but also upon one another for producing a great part of the phenomena of nature?
หน้า 258 - As the cold of snow in the time of harvest, so is a faithful messenger to them that send him: for he refresheth the soul of his masters.
หน้า 408 - The warp was placed perpendicularly ; the reed fell with a force of at least half a hundred weight ; and the springs which threw the shuttle were strong enough to have thrown a Congreve rocket ; in short, it required the strength of two powerful men to work the machine at a slow rate, and only for a short time.
หน้า 408 - Now you will not assert, gentlemen/ said I, ' that it is more difficult to construct a machine that shall weave, than one which shall make all the variety of moves which are required in that complicated game.
หน้า 387 - Every workman has a great quan- 15 tity of his own work to dispose of beyond what he himself has occasion for ; and every other workman being exactly in the same situation, he is enabled to exchange a great quantity of his own goods for a great quantity, or, what comes to the same thing, for the price of a 20 great quantity of theirs.

หน้า 408 - ... three movements, which were to follow each other in succession, there would be little difficulty in producing and repeating them. Full of these ideas, I immediately employed a carpenter and smith to carry them into effect. As soon as the machine was finished, I got a weaver to put in the warp, which was of such materials as sailcloth is usually made of.
