Страница 241 - An admirable and most forcible way to drive up water by fire, not by drawing or sucking it upwards, for that must be as the philosopher calleth it, infra spheeram activitatis, which is but at such a distance. But this way hath no bounder, if the vessels be strong enough ; for I have taken a piece of a whole cannon, whereof the end was burst, and filled it three...
Страница 261 - The trunk of an elephant that can pick up a pin or rend an oak, is as nothing to it. It can engrave a seal, and crush masses of obdurate metal like wax, before it, — draw out, without breaking, a thread as fine as gossamer, and lift a ship of war like a bauble in the air. It can embroider muslin, and forge anchors, — cut steel into ribands, and impel loaded vessels against the fury of the winds and waves.
Страница 284 - 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.
Страница 261 - By his admirable contrivance, it has become a thing stupendous alike for its force and its flexibility — for the prodigious power which it can exert, and the ease, and precision, and ductility, with which that power can be varied, distributed, and applied.

Страница 297 - Candlemas, when money transactions are settled in this country, were often so intense, that he passed great part of the night, and sometimes whole nights, at his desk. His garden also was tilled by his own hand ; he had a right of pasturage upon the mountains for a few sheep and a couple of cows, which required his attendance ; with this pastoral occupation, he joined the labours of husbandry upon a small scale, renting two or three acres in addition to his own less than one acre of glebe ; and the...
Страница 263 - Independently of his great attainments in mechanics, Mr. Watt was an extraordinary, and in many respects a wonderful man. Perhaps no individual in his age possessed so much and such varied and exact information, had read so much, or remembered what he had read so accurately and so well. He had infinite quickness of apprehension, a prodigious memory, and a certain rectifying and methodising power of understanding, which extracted something precious out of all that was presented to it.
Страница 405 - ... faithful Records, of all the works of Nature, or Art, which can come within their reach : that so the present Age, and posterity, may be able to put a mark on the Errors, which have been strengthened by long prescription : to restore the Truths, that have lain neglected : to push on those, which are already known, to more various uses : and to make the way more passable, to what remains unreveal'd.

Страница 122 - I mention it only, as it shows the solicitude and extreme activity which he had about every thing that related to his art; that he wished to have his objects embodied as it were, and distinctly before him; that he neglected nothing which could keep his faculties in exercise, and derived hints from every sort of combination.
