Strona 344 - Full many a gem of purest ray serene The dark unfathom'd caves of ocean bear : Full many a flower is born to blush unseen, And waste its sweetness on the desert air. Some village- Hampden, that, with dauntless breast, The little tyrant of his fields withstood, Some mute inglorious Milton here may rest, Some Cromwell guiltless of his country's blood. Th...
Strona 383 - Or hear'st thou rather pure ethereal stream, Whose fountain who shall tell ? before the sun, Before the heavens thou wert, and at the voice Of God, as with a mantle, didst invest The rising world of waters dark and deep, Won from the void and formless infinite.
Strona 111 - Wide roams. the Russian exile. Nought around Strikes his sad eye, but deserts lost in snow; And heavy-loaded groves; and solid floods, That stretch athwart the solitary vast Their icy horrors to the frozen main; And cheerless towns far-distant, never bless'd, Save when its annual course the caravan Bends to the golden coast of rich Cathay *, With news of human kind.
Strona 98 - Soon shall thy arm, unconquered steam, afar Drag the slow barge, or drive the rapid car ; Or on wide waving wings expanded bear The flying chariot through the fields of air...
Strona 458 - ... in a state of intense activity ; and a platina wire, communicating with the positive side, was brought in contact with the upper surface of the alkali. The whole apparatus was in the open atmosphere.
Strona 414 - And how well doth it execute its office! An anatomist, who understood the structure of the heart, might say beforehand that it would play; but he would expect, I think, from the complexity of its mechanism, and the delicacy of many of its parts, that it should always be liable to derangement, or that it would soon work itself out. Yet shall this wonderful machine go, night and day, for eighty years together, at the rate of a hundred thousand strokes every twenty-four hours, having, at every stroke,...
Strona 446 - To enrich thy walls: but thou didst hew the floods, And make thy marble of the glassy wave.
Strona 114 - That, ever busy, wheels the silent spheres; Works in the secret deep; shoots, steaming, thence The fair profusion that o'erspreads the Spring: Flings from the sun direct the flaming day; Feeds every creature ; hurls the tempest forth ; And, as on earth this grateful change revolves, With transport touches all the springs of life.
Strona 448 - ... that hydrogen, the alkaline substances, the metals, and certain metallic oxides, are attracted by negatively electrified metallic surfaces, and repelled by positively electrified metallic surfaces ; and contrariwise, that oxygen and acid substances are attracted by positively electrified metallic surfaces, and repelled by negatively electrified metallic surfaces ; and these attractive and repulsive forces are sufficiently energetic to destroy or suspend the usual operation of elective affinity.
Strona 71 - As home he goes beneath the joyous moon. Ye that keep watch in heaven, as earth asleep Unconscious lies, effuse your mildest beams, Ye Constellations, while your angels strike, Amid the spangled sky, the silver lyre.
