They explained the doctrine of the sphere and the apparent motions of the planets, but they had no instruments capable of measuring angular distances. The ingenious epicycles of Ptolemy prepared the way for the elliptic orbits and laws of Kepler, which in turn conducted Newton to the discovery of the law of gravitation, the grandest scientific discovery in the annals of our race.
Schlesien, what we call Silesia, lies in elliptic shape, spread on the top of Europe, partly girt with mountains, like the crown or crest to that part of the Earth; highest table-land of Germany or of the Cisalpine Countries; and sending rivers into all the seas. The summit or highest level of it is in the southwest; longest diameter is from northwest to southeast.
Long before the elliptic theory was thought of, it had been ascertained that the planets returned periodically to the same apparent places; the series of these places was, or might have been, completely determined, and the apparent course of each planet marked out on the celestial globe in an uninterrupted line.
The brown, orange, and pale-leadened narrow zones, which border the lower black mark of the elliptic ornament, can be seen gradually to become more and more softened and shaded into each other, with the upper lighter part towards the left-hand corner rendered still lighter, so as to become almost white, and at the same time more contracted.
When, therefore, the results of Kepler's laws were compared with ancient and modern observations it was found that they were not exactly represented by the theory. It was evident that the elliptic orbits of the planets were subject to change, but it was entirely beyond the power of investigation, at that time, to assign any cause for such changes.
Her lines were beautifully fine, with sharp flaring bows, billet head, and elliptic stern. The cabin accommodation was perhaps somewhat scanty, but this, in so small a vessel, built altogether for speed, not comfort, was scarcely to be avoided. The semicircular stern-cabin was, of course, appropriated to the captain, with a small state-room opening out from it in the starboard side.
The central or main niche is flanked on either side by quaintly contrived blank windows; and between the columns, at the depth of the recesses, are simple pilasters sustaining the elliptic arches, which serve to top and span the niches, the latter to be occupied by statues of the great creators and interpreters of the drama in every age and country.
The inconvenient old office, with its rows of leather buckets, and its harmless array of antiquated blunderbuses; its old-fashioned desks, dark with age, and begrimed with ink spattered by successive generations of bygone clerks; the low ceiling and quaint elliptic arches; the little fire-place near the counter, where Aurelius Attwood, with his good-humoured face, used to stand warming his coat-tails, and greeting the customers as they came in, were all so much in harmony with the staid, gray-headed clerks, and the quiet, methodical ways of the place, that when there, one might fancy he had stepped back for fifty years, or was looking upon a picture by Hogarth.
The orbits, or paths, about the sun are ovals or ellipses, almost circular, of which the sun occupies one focus, and they are so nearly in one plane, or at one level, that if seen from the sun, they would appear to wander along a narrow belt of the heavens, called the zodiac, which extends a few degrees on each side of the Elliptic or apparent course of the sun against the stars.
The allied if not identical H. Kalmiana is worthy of being included in a selection of these plants. H. URALUM. Nepaul, 1823. A neat but fragile species that attains to about a yard in height. Leaves rather small, elliptic, almost stalkless, and perforated with transparent dots. Flowers small and of a bright golden yellow.
