3 페이지 - Damn with faint praise, assent with civil leer, And without sneering, teach the rest to sneer, Willing to wound, and yet afraid to strike ; Just hint a fault and hesitate dislike...
47 페이지 - Watt was a comment on the text I have chosen, — the value of observation. Of the importance of the inventions of James Watt well may Arago, in his Eloge, speak as follows : " We have long been in the habit of talking of the age of Augustus and of the age of Louis XIV. Eminent individuals amongst us have likewise held that we might with propriety speak of the age of Voltaire, Rousseau, and Montesquieu. I do not hesitate to declare my conviction, that when the immense services already rendered by...
27 페이지 - Iris only object — was to determine experimentally the relative volumes of water and steam; that in the small apparatus he employed for this purpose, the steam could not elevate the liquid, according to the author's own account, above a few inches ; and that in the whole description of the experiment, there is not a single word that conveys the idea that Porta was aware of the power of this agent, or of the possibility of applying it to the production of a useful working machine.
47 페이지 - This, gentlemen, is a very abridged sketch of the benefits bequeathed to the world, by the machine of which PAPIN supplied the germ in his writings, and which, after so many ingenious exertions, WATT carried to such admirable perfection.
24 페이지 - Greece, in their turn, arrogated to themselves the honour of having been the birthplace of Homer. On the other side of the Channel, all have concurred in attributing the merit of it to the marquis of Worcester, of the illustrious house of Somerset ; on this side of the strait we maintain that it belongs to a humble engineer, almost altogether overlooked by biographers, viz., Solomon de Caus.
36 페이지 - I approach this inquiry with the firm determination of being impartial — with the most earnest solicitude to bestow on every improver the credit which is his due — and with the fullest conviction that I am a stranger to every consideration unworthy of the commission that you have conferred on me, or beneath the dignity of science originating in national prejudices. I declare, on the other hand, that I esteem very lightly the innumerable decisions which have...
23 페이지 - MIL, discovered that an iron-ball, or bomb, with very thick walls, and filled with water, exploded sooner or later when thrown into the fire, if its mouth were closed, or, in other words, if you prevented the free escape of the steam as it was generated. The power of steam was here demonstrated by a precise proof, which, to a certain point, was susceptible of numerical appreciation, t whilst at the same time it revealed itself as a dreadful means of destruction.
24 페이지 - M. Arago has claimed for France the invention of the steam engine. The English, he observes in his Memoir of Watt, have ascribed the honor to the Marquis of Worcester ; but on this side the channel, "we maintain that it belongs to a humble engineer, almost forgotten by our biographers, viz. Solomon de Caus." And in his 'History of the Steam Engine,' he asserts that " the idea of raising water by the elastic force of steam" belongs to the same individual.
46 페이지 - ... or to uplift the massy hammer, which with oft- repeated stroke thunders upon the enormous masses of red-hot iron just taken from the blast-furnace ; to cut with great shears thick metal bars, as easily as you divide a ribband with your scissors ; these, I repeat, are problems of a very secondary order, and which would not embarrass the most common engineer.
46 페이지 - Now, we find that it was to the production of an economical moving power, capable of effecting the unceasing and powerful strokes of the piston of a large cylinder, that Papin consecrated his life. The procuring afterwards from the strokes of the piston, the power requisite to turn the stones of a...
