Seite 12 - Then Paul stood in the midst of Mars' hill, and said, Ye men of Athens, I perceive that in all things ye are too superstitious. For as I passed by, and beheld your devotions, I found an altar with this inscription, TO THE UNKNOWN GOD. Whom therefore ye ignorantly worship, him declare I unto you.
Seite 29 - A CENTURY OF THE NAMES AND SCANTLINGS OF SUCH INVENTIONS, as at present I can call to mind to have tried and perfected which (my former notes being lost) I have, at the instance of a powerful Friend, endeavoured now in the year 1655 to set these down in such a way as may sufficiently instruct me to put any of them in practice.
Seite 30 - I have taken a piece of a whole cannon, whereof the end was burst, and filled it three-quarters full of water, stopping and screwing up the broken end, as also the touch-hole, and making a constant fire under it; within twentyfour hours it burst, and made a great crack...
Seite 114 - This potent commander of the elements — this abridger of time and space — this magician, whose cloudy machinery has produced a change on the world, the effects of which, extraordinary as they are, are perhaps only now beginning to be felt — was not only the most profound man of science, the most successful combiner of powers and calculator of numbers, as adapted to practical purposes, — was not only one of the most generally well-informed, — but one of the best and kindest of human beings.
Seite 56 - We have said that Mr. Watt was the great Improver of the steamengine ; but, in truth, as to all that is admirable in its structure, or vast in its utility, he should rather be described as its Inventor. It was by his inventions that its action was so regulated as to make it capable of being applied to the finest and most delicate manufactures, and its power so increased as to set weight and solidity at defiance. By his admirable...
Seite 126 - The manner of the carriage is by laying rails of timber from the colliery down to the river, exactly straight and parallel, and bulky carts are made with four rowlets fitting these rails, whereby the carriage is so easy, that one horse will draw four or five chaldrons of coals, and is of immense benefit to the coal merchants.
Seite 119 - ... instructive in no ordinary degree ; but it was, if possible, still more pleasing than wise, and had all the charms of familiarity, with all the substantial treasures of knowledge. No man could be more social in his spirit, less assuming or fastidious in his manners, or more kind and indulgent towards all who approached him. He rather liked to talk, at least in his latter years ; but though he took a considerable share of the conversation, he rarely suggested the topics on which it was to turn,...
Seite 117 - 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.
Seite 30 - So that, having a way to make my vessels so that they are strengthened by the force within them, and the one to fill after the other, I have seen the water run like a constant fountain stream forty feet high.
Seite 119 - As to their capacity he gave himself no trouble ; and, indeed, such was his singular talent for making all things plain, clear, and intelligible, that scarcely any one could be aware of such a deficiency in his presence. His talk, too, though overflowing with information, had no resemblance to lecturing or solemn discoursing, but, on the contrary, was full of colloquial spirit and pleasantry.
