Seite 331 - It was in a southern latitude. The sun had just set with placid appearance, closing a beautiful afternoon, and the usual mirth of the evening watch was proceeding, when the captain's order came to prepare with all haste for a storm. The barometer had begun to fall with appalling rapidity. As yet, the oldest sailors had not perceived even a threatening in the sky, and were surprised at the extent and hurry of the preparations: but the required measures were not completed, when a more awful hurricane...
Seite 87 - ... other side, and the spring has to begin its work again. The balance-wheel at each vibration allows one tooth of the adjoining wheel to pass, as the pendulum does in a clock ; and the record of the beats is preserved by the wheel which follows.
Seite xxx - I have post-coaches running day and night, on all the roads, to carry my correspondence ; I have roads, and canals, and bridges, to bear the coal for my winter fire ; nay, I have protecting fleets and armies around my happy country, to secure my enjoyments and repose. Then I have editors and printers, who daily send me an account of what is going on throughout the world...
Seite 380 - A column of two feet high rises with twice as much force as a column of one foot, and so in proportion for all other lengths; just as two or more corks strung together, and immersed in water, tend upwards with...
Seite 219 - ... a little more than a fourth part of the fatigue which it costs the second, because the exhaustion has relation to the time during which the muscles are acting.

Seite 452 - After a pause this fairy harp may be heard beginning with a low and solemn note, like the bass of distant music in the sky : the sound then swells as if approaching, and other tones break forth, mingling with the first, and with each other...
Seite xxx - Months afterwards it was ascertained, that at the time of observation the bells of the city of St. Salvador, on the Brazilian coast, had been ringing on the occasion of a festival: their...
Seite 570 - Language thus, at the present moment of the world's existence, may be said to bind the whole human race of uncounted millions into one gigantic rational being, whose memory reaches to the beginnings of written records, and retains imperishably the important events that have occurred; whose judgment...
Seite xxx - By my books I can conjure up before me, to vivid existence, all the great and good men of antiquity ; and for my individual satisfaction, I can make them act over again the most renowned of their exploits ; the orators declaim for me ; the historians recite ; the poets sing ; in a word, from the equator to the pole, and from the beginning of time until now, by my books I can be where I please.
Seite 410 - The common cause of waves is the friction of the wind upon the surface of the water. Little ridges or elevations first appear, which, by continuance of the force, gradually become loftier and broader, until they are the rolling mountains seen where the winds sweep over a great extent of water. The heaving of the Bay of Biscay, or still...
