In the interim, faith he, the other Comet could be feen with 
the naked eye until January 3 1 . when it was more than ten times 
further remote, than in its Perigee, although it was not by far fo 
bright, nor its ftrcamer flaming as this hath appeared. 
He willies, j hat all the changes that fliail fall out in this Comet s 
might be exactly obferv'djbecaufe of its not being fwiftj&nd the 
Motion of the Earth very fenfible, unlefs the Comet be exfream- 
ly remote, we fhould find much more light from f his, than the 
former Star, about the Grand Queftion , whether the Earth 
moves or not: this Author having all along entertained himfelf 
with the hopes, that the Motion of Comets would evince , whe- 
ther the Earth did move or not 5 and this very Comet feemed to 
him to have by defi'gn appeared for that end, if it had had more 
Latitude , and that confeqnently we might have feen it before 
Day-break. He wiflies alfo, that, if pofhble, it may be accu- 
rately obferved, whether it will not a little decline from its great 
Circle towards the South ; Judging, that fome important truth 
may be thence deduced, as well as if its motion retarded more, 
than the place of its Perigee ( which will be more exactly known 
when all the pafTed Oblervations fliail have been obtained) and 
its greateft Motion doe require. 
He fears only, that it being then to rife at Break of Day, ex- 
a£t Obfervations cannot be made of it : but he would, at leaft 
have it fought with Telefcopes, his Ephemcndes directing where* 
about it is to be. 
April 10. it was to be over a gain ft the point of the Triangle 
and from thence more Southerly by more than two degrees/ and 
April 1 1 • over againft the bright Star of Aries : April 1 7, over 
againft the Stars of the F/y, a little more Southerly, and May 4 *.. 
it is to be over againft the Pleiades , and about the fourth or fifdl 
of the fame Month, it is to be once more in Conjunction with the 
Sun ; after which time, the Sun will move from it Eaflward , and 
leave it towards the Weft; which will enable us to fee it again 
at abetter hour, provided the cleernefs of the Day-break be no 
impediment to us, He addeth, that this Star muft have been 
the third time in ConjunCHon with the Sun, about the time when 
it firft began to appear : and forefees, that from all thefe par- 
ticulars many confiderable confequences may be deduced.
