I. Obfervations upon the Comet , that appear'd in 
the Months of October, November, and De- 
cember, 1723. By the (Reverend Mr. Brad- 
ley, M. A . Brof. Aftron . Oxon. F. 5 . 
T HE (mall Comet which was feen in thefe Parts 
of Europe , in the Months of October, Novem- 
ber, and 'December , 1723. was firft obferved in En- 
gland by Dr. Halley , on O 6 tob. 9. between 7 and 8 of 
the Clock in the Evening} it appearing then to the na- 
ked Eye not much unlike a Star of the third Magni- 
tude. Looking at it through a Telefcope, he faw 
fome final 1 Telefcopical Stars near it, whofe Situation 
he noted together with the Comet’s, in order to fee 
which way it tended. About 9 he again viewed the 
Comet, and found it confiderably moved from its for- 
mer Station, having now palled a ftnall Star, which at 
the time of the firft Obfervation was on the other fide 
of it. Comparing the two Situations of the Comet to- 
gether, he perceived that its apparent Motion at that 
time was about 8 or 9 Minutes in an Hour, in a Di- 
rection towards Sagitta } and that the Comet parted 
very near, if it did. not wholly eclipfe the foremen- 
tioned Email Star, whofe place he afterwards found to 
be in & 7 0 22' 15" with 5 0 A N. Latitude. From 
the Situation of the Comet at the time of the firft Ob- 
fervation, lie judged that it was in Conjunction with 
the Star at 8 h. equal Time. Note that the equal, 
and not the apparent, Time, is likewife made ufe of in 
all the following Obfervations. 
The next Day he was pleafed to communicate to me 
the Subftance of what he had obferved, whereby! was
