For about a Fortnight past a COMET has been discovered in the East, about one or two o'Clock in the Morning, and nearly at an Hour's Distance from the Seven Stars South-Easterly, with a Tail about 20 Degrees in length, very bright, and directed towards the South West.
Wednesday Morning August 29, it was carefully observed, when a right Line, drawn from the Northernmost Pointer of the Great Bear, through Aldebaran, was found to pass directly through the Head of the Comet: Likewise a right Line drawn through the brightest Northerly Star of Gemini, and the Southernmost Star in the Top of the Bull's Horns struck the COMET. Also the Comet was in the Perpendicular of a right angled triangle made by Orion's right Shoulder and Aldebaran, the latter being in the right Angle.
Thursday Morning it was again observed about 2 o'Clock; and then a right Line drawn from Capella to the Comet left Aldebaran about 6 or 7 Minutes of a Degree above, or to the Westward of this Line. Likewise a right Line drawn from the brightest Star of Gemini through the Comet, left the Tip of the Southernmost Horn of Taurus about 35 Minutes of a Degree above, or to the Westward. Also a right Line drawn from Orion's right Shoulder through the nucleus of the Comet left the 4th of those Stars of equal Magnitude, which compose Orion's Shield, about 6 or 7 Minutes below, or to the Southward; beginning to reckon from the Northernmost Star of the Shield.
Therefore, August 30th,
Comet's Latitude, about-- 11 20 South.

The COMET was nearly in the right Line betwixt Orion's Left Shoulder and the next small Star in the same Shoulder Blade, about 15 m. of a Degree distant from the former;
At this last Observation the Tail was lengthened to 34 d. The Course is towards the Sun, and probably it will arrive at the Perihelion in about six or seven Days. The Inclination of the Orbit is about 24 d; the descending Node seems to have been nearly in 10 d. of Pisces; and it may continue visible in the Morning about 12 Days longer, when it will go off in a Line so near the Sun, and at such a Distance from the Earth, that it is not likely we shall have the Gratification of seeing it again in the Evening.
