the diftance of the Perihelion from the defcending 
Node 88° 45' io"j the Logarithm of the Perihelion 
diftance 9.528328 ; the Logarithm of the diurnal 
motion 0.66763d. 
From thele Elements (which are adapted to Dr. 
Halley’s general Table for the Motion of Comets in 
parabolic Orbits), I computed the places of this Co- 
met for the refpedtive times of the foregoing ob- 
servations, as in the following table ; which contains 
likewife the longitudes and latitudes deduced from 
the obferved right afcenfions and declinations, and 
alfo the differences between the computed and ob- 
ferved places. Thefe differences (no- where exceed- 
ing 40") Shew, that the elements here fet down will 
be Sufficient to enable future aftronomers to distin- 
guish this Comet upon another return j but as they 
do not correfpond with the elements of the orbit of 
any other Comet hitherto taken notice of, we cannot 
determine at prefent the period thereof,.
