 south; and Cellius in ♎ 13° 30′, with latitude 1° 00 south. But at 5h.30′ in the morning at Avignon, Galletius saw it in ♎ 13° 00′, with latitude 1° 00 south. In the University of La Fleche, in France, at 5h. in the morning (that is, at 5h.9′ at London), it was seen by P. Ango, in the middle between two small stars, one of which is the middle of the three which lie in a right line in the southern hand of Virgo, Bayers ψ; and the other is the outmost of the wing, Bayer's θ. Whence the comet was then in ♎ 12° 46′ with latitude 50′ south. And I was informed by Dr. Halley, that on the same day at Boston in New England, in the latitude of 42½ deg. at 5h. in the morning (that is, at 9h.44′ in the morning at London), the comet was seen near ♎ 14°, with latitude 1° 30′ south.

Nov. 19, at 4½h. at Cambridge, the comet (by the observation of a young man) was distant from Spica ♍ about 2° towards the north west. Now the spike was at that time in ♎ 19° 23′ 47″, with latitude 2° 1′ 59″ south. The same day, at 5h. in the morning, at Boston in New England, the comet was distant from Spica ♍ 1°, with the difference of 40′ in latitude. The same day, in the island of Jamaica, it was about 1° distant from Spica ♍. The same day, Mr. Arthur Storer, at the river Patuxent, near Hunting Creek, in Maryland, in the confines of Virginia, in lat. 38½°, at 5 in the morning (that is, at 10h. at London), saw the comet above Spica ♍, and very nearly joined with it, the distance between them being about ¾ of one deg. And from these observations compared, I conclude, that at 9h.44′ at London the comet was in ♎ 18° 50′, with about 1° 25′ latitude south. Now by the theory the comet was at that time in ♎ 18° 52′ 15″, with 1° 26′ 54″ lat. south.

Nov. 20, Montenari, professor of astronomy at Padua, at 6h. in the morning at Venice (that is, 5h.10′ at London), saw the comet in ♎ 23°, with latitude 1° 30′ south. The same day, at Boston, it was distant from Spica ♍ by about 4° of longitude east, and therefore was in ♎ 23° 24′ nearly.

Nov. 21, Ponthæus and his companions, at 7¼h. in the morning, ob served the comet in ♎ 27° 50′, with latitude 1° 16′ south; Cellius, in ♎ 28°; P. Ango at 5h. in the morning, in ♎ 27° 45′; Montenari in ♎ 27° 51′. The same day, in the island of Jamaica, it was seen near the beginning of ♏, and of about the same latitude with Spica ♍, that is, 2° 2′. The same day, at 5h. morning, at Ballasore, in the East Indies (that is, at 11h.20′ of the night preceding at London), the distance of the comet from Spica ♍ was taken 7° 35′ to the east. It was in a right line between the spike and the balance, and therefore was then in ♎ 26° 58′, with about 1° 11′ lat. south; and after 5h.40′ (that is, at 5h. morning at London), it was in ♎ 28° 12′, with 1° 16′ lat. south. Now by the theory the comet was then in ♎ 28° 10′ 36″, with 1° 53′ 35″ lat. south.

Nov. 22, the comet was seen by Montenari in ♏ 2° 33′; but at Boston
