In one of the earliest of Herschel's memoirs, we find, that the apparent sidereal diameters are proved to be for the greater part factitious, even when the best made telescopes are used. Diameters estimated by seconds, that is to say, reduced according to the magnifying power, diminish as the magnifying power is increased. These results are of the greatest importance.
Long-continued and close observations were necessary, before some of these astronomical results that have reached our times could have been ascertained. Thus the Babylonians had fixed the length of a tropical year within twenty-five seconds of the truth; their estimate of the sidereal year was barely two minutes in excess. They had detected the precession of the equinoxes.
Till then she had been but his Princess, the exquisite lady whom it had amused to wander with him into the pays du tendre. She had been as far above him as the now disregarded stars. She had come down with a carnival domino over her sidereal raiment, and had met him on carnival equality. He beau masque! He, knowing her, had fallen beneath her starry spell.
With the zaimph which was wrapped about him, he looked like a sidereal god surrounded by the firmament. The slaves were going to fall upon him, but she stopped them: "Touch it not! It is the mantle of the goddess!" She had drawn back into a corner; but she took a step towards him, and stretched forth her naked arm: "A curse upon you, you who have plundered Tanith!
Those who hold it legitimate to argue from phenomena to noumena, may rightly contend that the Nebular Hypothesis implies a First Cause as much transcending "the mechanical God of Paley," as this does the fetish of the savage. R. A. Proctor has given various further reasons for the conclusion that the nebulæ belong to our own sidereal system. Babinet for rejection of the Nebular Hypothesis.
In the centre of this space stood a wooden building, or shed, twenty-five feet square, painted a dark red, its roof on a level with the height of the outer parapet. The bishop opened the door with another key and threw the windows wide, disclosing a canvas-hooded telescope in the centre, chairs and tables bearing astronomical instruments, and sidereal maps upon the walls.
The human mind at this one bound found opportunity to explore and to know a sidereal sphere more than twice as extensive as had ever been previously penetrated by the gaze of man. Nor is this all. The ambition of American astronomers and American philanthropists has not been content with even the prodigious achievement of the Lick telescope.
Its surface throbs and palpitates and quivers and yields to pressure as only living organisms do. The tides can hardly be regarded as evidences of its breathing, as Kepler thought they could, but they are proof of how closely it is held in the clasp of the heavenly forces. It is like an apple on the vast sidereal tree, that has mellowed and ripened with age.
Spectroscopic investigations of stellar movements may confidently be expected to play a leading part in the unravelment of the vast and complex relations which we can dimly detect as prevailing among the innumerable orbs of the sidereal world; for it supplements the means which we possess of measuring by direct observation movements transverse to the line of sight, and thus completes our knowledge of the courses and velocities of stars at ascertained distances, while supplying for all a valuable index to the amount of perspective foreshortening of apparent movement.
It must seem rather terribly humdrum here after Paris and Naples, and well most places, at that rate, as you know them." Richard shifted his position. And the crystal moon encompassed by golden bands, crossing and intersecting one another like those of a sidereal sphere, gleamed as with an inward and unearthly light, swinging slowly upon the movement of his hand.
