Read Dec. 22, "y Deferred to give an account of my 
175 7 * y obfervations upon the Comet that 
hath lately appeared, till I could fettle the places of 
the ftars with which it had been compared ; feveral 
of them not being inferted in the Britifh catalogue, 
and thofe which are, requiring fome fmall corrections, 
which I have lince made from my own obfervations. 
When I firft difcovered this Comet, it appeared 
to the naked eye like a dull ftar of the 5th or 6th 
magnitude j but viewing it thro’ a feven-foot Tele- 
fcope, I could perceive a fmall Nucleus (furrounded, 
as ufual, with a nebulous atmofphere), and a fhort 
tail extended in a direction oppofite to the fun. 
Some fmall {tars then appearing in the field of 
the telefcope with the Comet, I meafured its di- 
ftance from them with a Micrometer ; and on Sep- 
tember i2<* at i6 h 1 ' mean time, I found it to be i° 
13' 5" diffant from a fmall flar, whofe right afcen- 
fion was afterwards found to be 8p° 45)' 40 ' and de- 
clination 36° 1 1 ' 30" north : and near the fame time 
the Comet was obferved to be 43' 10 ' from another 
ftar, whofe right afcenfion was po° 2 o' o" and decli- 
nation 3 5 0 12' o" north.
