[8] The tail of the first comet of 1865 (observed in the Southern Hemisphere) attained the unprecedented length of 150°.—M. N. R. A. S., vol. xxv., p. 220.
[9] This chapter is the substance of a paper read before the American Philosophical Society, November 19, 1869.
[10] Halley's comet in aphelio is too remote from the plane of the ecliptic to be much disturbed by Neptune. Has the original position of the orbit been changed by Jupiter's influence?

[12] Others, it was supposed, might have originated within the system,—a view which the writer has not wholly abandoned.

[21] New Concord is close to the Guernsey county line. Nearly all the stones fell in Guernsey.
[22] The first indication of the approaching shower was the appearance of meteors in unusual numbers at Malta, on the 13th of November, 1864. In 1865, as observed at Greenwich and other stations, they were still more numerous.

[24] Recent in comparison with the origin of the August meteors, which constitute a continuous ring.
[25] Mr. Swift, of Marathon, N. Y., had two or three days priority in the discovery of this comet, but unfortunately delayed his announcement of the fact.
