final difappearing. 
The 23d, the fky being very clear, I again faw 
the comet ; its appearances were the fame as the 
two preceding days. I compared the nucleus with 
a very fmall ftar, only of the loth magnitude, 
which I have fettled by comparing it with the 46th 
ftar of Pifces of the 6th magnitude,, according to 
Flamftead’s catalogue. See the pofition of this flar 
in the firft table, N° 27. The pofition of the comet 
is fet down in the fecond table. 
The 24th in the evening, the fog, thin clouds, 
and vapours about the horizon fuffered me to take

ftars of Pegafus called Algenib and Markab. Thefe 
differences did not appear to me to be fo exadt as to 
depend upon the determination of the comet from 
them, fo I fhall give no account of them. 
The 25th in the evening, the flcy being clear at 
times, I again faw the comet ; its light was increafed, 
and the nucleus looked brighter than before, but 
without any appearance of a tail. I compared it 
diredlly with a ftar which is the i6th of Pifces, in 
the order of Flamftead’s catalogue. It was likewife 
compared with N° 26 of my table. The comet was 
fufficiently vifible this night to be feen thro’ a com- 
mon two feet telefcope, and even thro’ one of a 
fingle foot. At four minutes pafl feven, the comet 
was ftill to be feen thro’ the telefcope at the height 
of 13° above the horizon.
