again waited for its riling, the Heavens being now exceeding 
ferene and clear: at about 2 a Clock after the Midnight fol- 
lowing I faw the Tail raifed almoft perpendicular to the Ho- 
rizon 5 fo6n after the Head appeared through a thin vapor, 
from which the Tail pointed as near , as J could guefs, upon 
the * in the k^ee of CaJ^opea, its length being about 6 degrees, 
and breadth at the top about 7 or 8 minuies.Viewing the Head 
with a Telefcope of 16 foot,l found it was not perfeflly round, 
bur indented^and not near one minute diameter^. Afterwards I 
haftedtomeafureits diftances from fereral fixed Stars, which 
wefe as follow ;

And admitting with Mr. Hevelitts the place of Mirach now in T 
21° 40' 34'*, with North latitude 25^ 57*, its diftance from 
^Igol will be 230 42* 4©!*, and the place of the Head of the

At 15»» 28* I flate the corrcft diftance of the Comets head

agreeing very well with the place derived from the former di- 
ftances from two other and different Stars, 
The Tail was not, it feeros, direflly oppofite to the Sun, for- 
the Suns place was now 30^07* ; but the Comet being in 
14'' 47* of the fame Sign, that is 1° 4©* in confcquence of the 
Sun, the Tail ought, if it had been exaftly oppofite to the Sun,
