Besides, even you have too much regard to the land of Kit North, to entertain any desire to see its most attractive shrine of pilgrimage too suddenly eclipsed; and why should you court such an exposure of popular fickleness, when about to become yourself "the comet of a season," and to go through that brilliant perihelion, in which, reversing the feat of Horace with his lofty head, you will sweep away all other stars with a swinge of your luminous caudality?
The direction of the axis major of the orbit, which was found by calculating the longitude of the comet's perihelion. The perihelion distance from the sun, which settled the precise form of the parabola. The motion of the comet, as being retrograde, or, unlike the planets, from east to west.
"Because the heat and cold would be equalized on our globe. It has been calculated that, had our earth been carried along in its course by the comet of 1861, at its perihelion, that is, its nearest approach to the sun, it would have undergone a heat 28,000 times greater than that of summer.
But the ethereal substance long supposed to obstruct the movement of Encke's comet would there be nearly 2,000 times denser than at the perihelion of the smaller body, and must have exerted a conspicuous retarding influence. That none such could be detected seems to argue that no such medium exists. Further evidence of a decisive kind was not wanting on the question of identity.
Hence these almost infinitely numerous particles of planet-spray, as we might call it, as well as those formed by the condensation of the metallic vapours accompanying them, would forthwith begin to part company: some going rapidly in advance, and others falling behind; until the stream of them, perpetually elongating, formed an orbit round the Sun, or rather an assemblage of innumerable orbits, separating widely at aphelion and perihelion, but approximating midway, where they might fall within a space of, say, some two millions of miles, as do the orbits of the November meteors.
Severally subject to great heat at perihelion, these would behave more or less differently. Once more, it would ordinarily happen that detached swarms of meteors projected as implied, would carry with them masses of vapours and gases; whence would result the cometic constitution now insisted on. And sometimes there would be like accompaniments to meteoric streams.
Whether this heat was the result of collision or of its near approach to the sun at perihelion, they could not tell, though the latter explanation seemed most simple and probable. When at about the centre of the nucleus they were in semi-darkness not twilight, for any ray that succeeded in penetrating was dazzlingly brilliant, and the shadows, their own included, were inky black.
Wollaston had made a drawing of the orbit and its elements; but, having left it in town, he described the lines so accurately without naming them, that I remarked at once, "That is the curtate or perihelion distance," which pleased him greatly, as it showed how accurate his description was.
The perihelion of this dance seems, indeed, to have been in the reign of Charles II. Georgian writers treated it somewhat as a survival, and were not always even tender to it. Says a writer in Bladud's Courier, describing a 'soire'e de beaute'' given by Lady Jersey, 'Mrs.
Mercury is in perihelion on the 1st, becomes stationary on the 9th, and reaches his greatest elongation on the 19th, when he may be seen before sunrise, as well as a few preceding and succeeding mornings; be rises on the abovementioned day at 6h. 8m.
