extends from 200,000 to 500,000 miles from the sun. Beyond the inner corona is the outer corona as already known and photographed during the eclipses of 1870 and 1871, and extending about a million miles from the sun. But far outside the outer corona there is a region occupied by matter so situated and so illuminated (or possibly self-luminous) as to present the appearance of long rays extending, if we may judge from observations hitherto made, directly from the sun to a distance of 5,000,000 miles. Outside this region again lies another in which, whether by the combination of multitudes of such rays as are seen separately close to the sun or through the presence of matter in other forms, a softened luminosity prevails which during total eclipse can be traced along the zodiac at least 10,000,000 miles from the surface of the sun. Lastly, from observations made during evening twilight in spring and during morning twilight in autumn (at which twilight hours the zodiac near the sun is most nearly upright during the year) we can trace the extension of the zodiacal luminosity seen by Langley and Newcomb, to distances exceeding seven or eight times at least those to which they traced it during total eclipse. Kay, there are reasons for believing that at times this luminosity has been traced to such a distance from the sun as to show that the zodiacal matter extends much farther from him than the orbit of our own earth.
Now, in one sense, the relations here presented are not new. The zodiacal light has been known from the time of Childrey, if not from that of Tycho Brahe. Mathematicians have long seen that it must belong to a solar appendage, rejecting utterly the doctrine advanced by some that it comes from matter traveling round our own earth. Again, the long coronal rays had been very confidently regarded by most mathematical astronomers, and indeed by all who had sufficiently studied the evidence, as belonging to matter near the sun. And though the zodiacal had never before been recognized during totality, and so the gap between the outermost coronal rays and the innermost part of the zodiacal seen during twilight had never been observationally filled up, yet the mind's eye of science had clearly discerned even that portion of the zodiacal. Still the recognition of the whole range of solar surroundings, in such sort that no question can any longer, it should seem, be raised as to their reality, even by those least able to follow scientific reasoning, can not but be regarded as an important step.CONCERNING HONORS TO SPIES.
Mr. Cyrus W. Field has dedicated a memorial stone to the memory of André. It marks the place of his execution and burial. It was uncovered at noon, October 2d, as nearly as possible at the same hour that André was banged. But few persons were present, and not a word was spoken by any one.
The monument is a plain polished block of Maine granite, five feet in height and three and one half feet square. On the side toward the west is the following inscription:
Beneath was the name—
"Arthur Penrhyn Stanley, Dean of Westminster."
On the south side the inscription reads as follows:
"Sunt Lacrymæ rerum et mentem mortalia tangunt."—Virgil, "Æneid," I., 462.
The only other inscription is upon the north side, and is this:
An inscription will be placed on the east side next year, the centennial of the execution.
