xxvii ページ - English are not the least in worth or fame. The world to Bacon does not only owe Its present knowledge, but its future too. Gilbert shall live, till loadstones cease to draw, Or British fleets the boundless ocean awe.
vii ページ - ... since every language is so full of its own proprieties that what is beautiful in one is often barbarous, nay sometimes nonsense, in another, it would be unreasonable to limit a translator to the narrow compass of his author's words; 'tis enough if he choose out some expression which does not vitiate the sense.
vii ページ - That servile path thon nobly dost decline, Of tracing word by word, and line by line. A new and nobler way thou dost pursue, To make translations and translators too : They but preserve the ashes, thou the flame, True to his sense, but truer to his fame.
98 ページ - Thus a certain* gauzy texture of silk, commonly called sarsnet, when quickly laid over amber immediately after friction, hinders the body's* attraction ; but if it be interposed midway between the two bodies, it does not altogether annul the attraction. Moisture from steam, a breath from the mouth, water thrown on the amber, instantly check the effluvium. But olive-oil that is* light and pure does not prevent it, and even rubbing amber* with a warm finger dipped in the oil does not prevent attraction....
xlvii ページ - PREFACE. TO THE CANDID READER, STUDIOUS OF THE MAGNETIC PHILOSOPHY. SINCE in the discovery of secret things and in the investigation of hidden causes, stronger reasons are obtained from sure experiments and demonstrated arguments than from probable conjectures and the opinions of philosophical speculators of the common sort ; therefore to the end that the noble substance of that great loadstone, our common mother (the earth), still quite unknown, and also the forces extraordinary and exalted of this...
313 ページ - I wonder much why the globe of earth with its effluences should have been by (Aristotle) and his followers condemned and driven into exile and cast out of all the fair order of the glorious universe, as being brute and soulless. . . . As for us, we deem the whole world animate, and all globes, all stars, and this glorious earth, too, we hold to be from the beginning by their own desinate souls governed and from them also to have the impulse of self-preservation.
45 ページ - Iron ore has and acquires poles, and arranges itself with reference to the earth's poles MEN are deplorably ignorant with respect to natural things, and modern philosophers, as though dreaming in the darkness, must be aroused and taught the uses of things, the dealing with things; they must be made to quit the sort of learning that comes only from books, and that rests only on vain arguments from probability and upon conjectures.
85 ページ - ... false, disgracefully inaccurate. Now in order clearly to understand by experience how such attraction takes place, and what those substances may be that so attract other bodies (and in the case of many of these electrical substances, though the bodies influenced by them lean toward them, yet because of the feebleness of the attraction they are not drawn clean up to them, but are easily made to rise), make yourself a...
23 ページ - In like manner the loadstone has from nature its two poles, a northern and a southern; fixed, definite points in the stone, which are the primary termini of the movements and effects, and the limits and regulators of the several actions and properties. It is to be understood, however, that not from a mathematical point does the force of the stone emanate, but from the parts themselves; and all these parts in the whole — while they belong to the whole — the nearer they are to the poles of the...
325 ページ - that via lactea was a meteor ; and not onely of Aristotle, but almost all before him. that there were still higher, deeper, more immeasurable ; and yet this incomprehensible primum mobile would have to be of matter, of enormous altitude, and far surpassing all the creation below in mass, for else it could not make the whole universe down to the earth revolve from east to west, and we should have to accept a universal force, an unending despotism, in the governance of the stars, and a hateful tyranny....
