Page 20 - That day, as other solemn days, they spent In song and dance about the sacred hill; Mystical dance, which yonder starry sphere Of planets, and of fixed, in all her wheels Resembles nearest, mazes intricate, Eccentrick, intervolved, yet regular Then most, when most irregular they seem ; And in their motions harmony divine So smooths her charming tones, that God's own ear Listens delighted.
Page 316 - Bacon, that the words of prophecy are to be interpreted as the words of one 'with whom a thousand years are as one day, and one day as a thousand years.
Page 10 - Kepler also deduced from observation, that the squares of the periodic times of the planets, or the times of their revolutions round the sun, are proportional to the cubes of their mean distances from...
Page 28 - His true position is in the diagonal of the parallelogram, whose sides are in the ratio of the velocity of light to the velocity of the earth in its orbit, which is as 190000 to 19.
Page 298 - Jupiter ; it then gradually diminished in splendour, and, having exhibited all the variety of tints that indicate the changes of combustion, vanished sixteen months after its discovery, without altering its position. It is impossible to imagine anything more tremendous than a conflagration that could be visible at such a distance.
Page 296 - The distance of the fixed stars is too great to admit of their exhibiting a sensible disc ; but, in all probability, they are spherical, and must certainly be so if gravitation pervades all space, which it may be presumed to do, since Sir John Herschel has shown that it extends to the binary systems of stars.
Page 318 - These formulae, emblematic of Omniscience, condense into a few symbols the immutable laws of the universe. This mighty instrument of human power itself originates in the primitive constitution of the human mind, and rests upon a few fundamental axioms, which have eternally existed in Him who implanted them in the breast of man when He created him after His own image.
