Seite 153 - Fresh pearls to their enamel gave, And the bellowing of the savage sea Greeted their safe escape to me. I wiped away the weeds and foam, I fetched my sea-born treasures home; But the poor, unsightly, noisome things Had left their beauty on the shore With the sun and the sand and the wild uproar.
Seite 411 - On the Calorific Effects of Magneto-Electricity, and on the Mechanical Value of Heat.
Seite 6 - that every particle of matter in the universe attracts every other particle, with a force whose direction is that of the line joining the two, and whose magnitude is directly as the product of their masses, and inversely as the square of their distances from each other.
Seite 406 - But though the natural works of God can never by any possibility come in contradiction with the higher things that belong to our future existence, and must with everything concerning Him ever glorify Him, still I do not think it at all necessary to tie the study of the natural sciences and religion together, and, in my intercourse with my fellow creatures, that which is religious and that which is philosophical have ever been two distinct things.
Seite 171 - An eminent friend of mine often speaks of the mistake of those physicians who regard man's ailments as purely chemical, to be met by chemical remedies only. He contends for the psychological element of cure. By agreeable emotions, he says, nervous currents are liberated which stimulate blood, brain, and viscera. The influence rained from ladies' eyes enables my friend to thrive on dishes which would kill him if eaten alone. A sanative effect of the same order I experienced amid the spray and thunder...
Seite 169 - He waded in. It evidently required all his strength to steady him. The water rose above his loins, and it foamed still higher. He had to search for footing, amid unseen boulders, against which the torrent rose violently. He struggled and swayed, but he struggled successfully, and finally reached the shallower water at the other side. Stretching out his arm, he said to me, ' Now, come on ! ' I looked down the torrent, as it rushed to the river below, which was seething with the tumult of the cataract....
Seite 170 - Prudence was at my elbow, whispering dissuasion; but taking everything into account, it appeared more immoral to retreat than to proceed. Instructed by the first misadventure, I once more entered the stream. Had the alpenstock been of iron it might have helped me; but as it was, the tendency of the water to sweep it out of my hands rendered it worse than useless. I, however, clung to it by habit. Again the torrent rose, and again I wavered; but by keeping the left hip well against it, I remained...
Seite 173 - We reached the cave and entered it, first by a wooden way carried over the boulders, and then along a narrow ledge, to the point eaten deepest into the shale. When the wind is from the south, the falling water, I am told, can be seen tranquilly from this spot; but when we were there, a blinding hurricane of spray was whirled against us.
Seite 48 - ... and striking proof of this identity. A concave mirror produces beyond the object which it reflects an inverted and magnified image of the object ; withdrawing, for example, our iodine solution, an intensely luminous inverted image of the carbon points of the electric light is formed at the focus of the mirror employed in the foregoing experiments. When the solution is interposed and the light is cut away, what becomes of this image ? It disappears from sight, but an invisible thermograph remains,...
Seite 74 - Indeed the domain of the senses in Nature is almost infinitely small in comparison with the vast region accessible to thought which lies beyond them. From a few observations of a comet when it comes within the range of his telescope, an astronomer can calculate its path in regions which no telescope can reach; and in like manner, by means of data furnished in the narrow world of the senses, we can make ourselves at home in other and wider worlds, which can be traversed by the intellect alone.
