Strana 205 - Let there be light, said God ; And forthwith light Ethereal, first of things, quintessence pure, Sprung from the deep ; and from her native east To journey through the aery gloom began, Sphered in a radiant cloud, for yet the sun Was not ; she in a cloudy tabernacle Sojourn'd the while.
Strana 194 - Wise men have said, are wearisome : who reads Incessantly, and to his reading brings not A spirit and judgment equal or superior (And what he brings, what needs he elsewhere seek?) Uncertain and unsettled still remains, Deep versed in books and shallow in himself, Crude or intoxicate, collecting toys, And trifles for choice matters, worth a sponge ; As children gathering pebbles on the shore.
Strana ix - In the northern hemisphere the cyclone rotates in a direction contrary to that in which the hands of a clock move, but in the southern hemisphere the rotation coincides with the movement of the hands.
Strana 42 - 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.
Strana 61 - There is not, perhaps," said this great and sound astronomer, " another object in the heavens that presents us with such a variety of extraordinary phenomena as the planet Saturn ; a magnificent globe encompassed by a stupendous double ring ; attended by seven satellites; ornamented with equatorial belts; compressed at the poles ; turning...
Strana iv - To ask or search I blame thee not, for heaven Is as the book of God before thee set, Wherein to read his wondrous works, and learn His seasons, hours, or days, or months, or years.
Strana 38 - ... varies inversely as the square of the planet's distance from the sun. There is a slight error in Nichol's statement that ' by an appropriate choice of an eccentric circular orbit the sun's motion relative to the earth or to any planet,' (or, which is the same thing, any planet's motion relatively to the sun), 'may be very closely approximated to,' on the supposition of uniform velocities.
Strana 201 - This world was once a fluid haze of light, Till toward the centre set the starry tides, And eddied into suns, that wheeling cast The planets...
Strana iv - But this I do say, and would wish all men to know and lay to heart, that he who discerns nothing but Mechanism in the Universe has in the fatalest way missed the secret of the Universe altogether. That all Godhood should vanish out of men's conception of this Universe seems to me precisely the most brutal error, — I will not disparage Heathenism by calling it a Heathen error, — that men could fall into. It is not true...
Strana 61 - Saturnian : the globe and satellites enlightening the dark parts of the rings : and the planet and rings throwing back the sun's beams upon the moons, when they are deprived of them at the time of their conjunctions.
