SIR, 
I Have this day received a Note from Sr. Jonas Moore, in 
which he inforajs me, that you have received Papers con- 
cerning the late Comet both from Mr. Hevelius and W.Gaffini^ 
and that you defire to know what I obferved of it. I am glad 
to hear you have accounts of it from two fuch able perfons, 
who having obferved and made theories for the Comets which 
appeared near the fame place twice of late at twelve years in- 
terval , viz in 1653, and 1665, may beft inform us , what 
conformity there is betwixt the Motions of this and them, and 
whether it may probably be the fame returned hither after two 
revolutions; or another: My Obfervations of it,by rcafonof 
our cloudy Nights, were fo few, that I can determine nothing 
from them ; however perhaps they maybe of ufe to others, 
who had more frequent opportunities , and therefore fuch as 
they are, they are at your fervice. 
The firft time that the Comet was taken notice of with us, that 
1 can hear of, was about the middle of our Eajler week ; I be- 
lieve it might have been obferved long before, had not the un- 
wonted cloudinefs of our Heavens (which has permitted me to 
obfervebut 4 of almofl: 50 appulfesof the Moon and Planets 
to fixed Stars forefeen hitherto) prevented. The firft cerrain 
notice I had of it was on 2 r. I waited the rifing of the 
Cornet^ but immediately after midnight the Heavens were over-
