Explanation of the two Tables annexed to this 
Memoir. 
The firft table contains the right afcenfions and 
declinations of the ftars, both of the new ones and 
of thofe in Fiamftead’s catalogue, for the time of the 
obfervations. It appears from this table, that the 
comet has furnirtied me with an opportunity of de- 
termining the pofition of 29 new ftars, which were 
not vet known, and which have ferved for the de- 
termination of the comet. , 
The fecond table contains all the places of the 
comet, as well in right afcenfion and declination, as 
in longitude and latitude, concluded from its htua- 
tion obferved relatively to the ftars, whether new 
ones or already known. Thefe are the titles of each 
column: The ift points out the days of the month ; 
the 2d, the true time of each obfervation j the 3d, 
the right afcenfions of the comet obferved ; the 4th, 
the declinations ; the 5th, the longitudes obferved ; 
the 6th, the latitudes j the 7th, the differences of 
pafiage in right afcenfion of the comet and the ftars, 
marked with the fign — when the comet preceded 
the ftar or was to the Weft of it, and with + when 
it followed the ftar or was to the Eaft. This differ- 
ence, according to the fign, being either added to or 
fubtra<ffed from the right afcenfion of the ftar fet 
down in the firft table, with which the comet was 
compared, will give its right afcenfion. The 8th 
column (hews the differences of declination between 
the comet and the ftars, marked likewife with 
and and which, being accordingly either added
