After the age of trace out more accurately the exact curves in which the planets Ptolemy little progress appears to have been made, and even moved, and to ascertain their various distances, sizes, and rates known truths were to a great extent forgotten. His system was of motion. This work was taken up by Kepler, who has someindeed universally received for many centuries, more especially times been called the “ Legislator of the Heavens," as it was he as it was supported by the authority of Aristotle ; and fresh who first laid down the laws and rules which govern the moveadditions to it, in the shape of eccentrics and epicycles, were ments of the heavenly bodies. We shall notice more about this made ; but few, if any, new discoveries appear to have been celebrated astronomer shortly, but must first look at the labours effected, and no noteworthy name appears on the

He was of Danish extraction, and was born very shortly after After the fall of the Roman empire the science found a home the death of Copernicus. It is said that his attention was first among the Arabians, who, in the eighth century, seem to have directed to the science of astronomy by an eclipse which dovoted much attention to its study, and to have made con happened at the time predicted, in the year 1560, and incited siderable advances in it. By them the length of the solar year him to learn something of the wonderful science which enabled was calculated to within a very little of its true amount; the such predictions to be made. When at the University of Leipsic, obliquity of the

ecliptic was also measured ; and at a place in much of his night was often devoted to observation of the stars, the desert, near Palmyra, the length of a degree was ascertained and thus he soon attained considerable proficiency; but there with very creditable accuracy. The Ptolemaic system was, how is one thing which tends rather to lower him in our estimation, ever, firmly received, though many of the more thoughtful and and that is his partial rejection of the Copernican system, and careful observers seem to have been far from satisfied with it, the proposal of a new one, in which the earth occupied the

In this way he continued in a large orbit, he thought the fixed stars ought to appear in a to try one hypothesis after another, submitting each to the test different position when seen from one extremity of the orbit to of most careful observation, till at length no fewer than nineteen that which they occupied when seen from the other extremity; different theories had been proposed, and the movements of the and not being able to observe this change, he concluded that the planets compared with those which were calculated by these earth must be at rest. The principle of this argument was theories;

and yet the true solution of the problem was still unright, and in reality there is a minute difference in the appearance found. His perseverance, however, never failed, and he toiled of the stars; it is, however, too minute to be observed, except on, though eight long years had been occupied in the task. One by the most delicate instruments. The reason why it is not important negative result he had, however, arrived at, and this more clearly seen is that, great as is the diameter of the earth's was that, whatever was the nature of the curve the planeta orbit, the distance of even the nearest fixed star is so immensely described, it was not a circle, nor a combination of circles. This greater that the change produced is scarcely visible. We may was one great step towards the solution of the task. From the notice this same effect as we are carried rapidly along in a train; very earliest ages it had been assumed that, as the circle the objects situated near to the line of railway seem to move seemed the perfection of form, all the heavenly bodies must more past us very rapidly, those further off have a less apparent in circles; but Kepler now cast off this trammel, and then speed, while lofty objects in the distance scarcely seem to move applied himself afresh to his task. at all.
