The planets are subject to disturbances of two kinds , both resulting from the constant operation of their recip rocal attraction ; one kind , depending upon their positions with regard to each other , begins from zero , increases to a ...

The accuracy of that work is obviously of extreme importance to a maritime nation : we have reason to hope that the new Ephemeris , now in preparation , will be by far the most perfect work of the kind that ever has been published .

Were the earth spherical , this effect would not be produced , and the equinoxes would always correspond with the same points of the ecliptic , at least as far as this kind of motion is concerned . But another and totally different ...

Now in the tides there ar three distinct kinds of oscillations , depending on different causes , and producing their effects independently of each other , which may therefore be PHYSICAL SCIENCES . 87 Junis made his observations at ...

The oscillations of the first kind , which are very small , are independent of the rotation of the earth ; and as they depend upon the motion of the disturbing body in its orbit , they are of long periods . The second kind of ...

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.
