[Footnote 89: The equatorial diameter of Saturn in English miles is 79,147; its density, ·12, the Earth = 1; its distance from the sun, 906,200,000 miles; and the inclination of its orbit to the ecliptic, 2° 29' 36".] [Footnote 90: Our author, it must be understood, is considering these questions apart from the Scriptural standpoint.] [Footnote 91: William Drummond.] [Footnote 92: Samuel Rogers.] APPENDIX. APPENDIX. THE SOLAR ECLIPSE OF 1870. The total Solar Eclipse, which is to render famous the month of December in the present year--famous, that is, in astronomical annals--deserves, we think, some special notice in our pages. In 1860, the _Himalaya_ was fitted out by Government for the use of the _savants_ desirous of observing the Solar Eclipse visible that year in Spain, and the results of the expedition were so important as fully to warrant the liberality of the Government. The eclipse of the present year will also be visible in Spain, but the path of the sun's shadow will pass as far north as Cape Spartel, and, crossing Algeria, will go northwards, _via_ Sicily, and in the direction of Constantinople. The totality of the eclipse will not last so long as that of the Indian eclipse in 1868. The sun will be hidden from sight for no longer period than about two minutes twelve seconds, and whatever observations our astronomers are anxious to make must be made in that brief interval. It may not unreasonably be suggested that, in so short a time, no data can be ascertained worth the cost and trouble the proposed expedition will necessitate; but the reader requires to be informed that the most valuable acquisitions lately won in the region of solar physics have been the result of observations which may almost be described as momentary. What, then, is the important point on which our astronomers hope to gain information from a close examination of the approaching eclipse? This question has been ably answered by a well-informed writer in the _Daily News_. The great problem to be solved is that of the strange appearance of the solar corona; of that glory of light which rings round the great luminary when totally eclipsed, to it, as some astronomers assert, a purely optical phenomenon, or, as others more reasonably declare, "one of the most imposing of all the features of the solar system." It is true that the former opinion is held by such men as Faye, Lockyer, and Professor Airy; but if it be founded on fact, the phenomenon loses all its importance, and nearly all its interest. If the other opinion prove correct, and the corona is discovered to be in reality an appendage of the orb of day, then the mind must at once acknowledge its unsurpassed splendour, its magnificent proportions. As its glow and ethereal radiancy often extends several degrees from the eclipsed sun, its diameter cannot be less than 2,800,000 miles.
