In that Trad he obferves, firft in General \ that this fecond 
Comet is contrary to the precedent, almoft in all particulas : fe* 
ing that the former moved very fwift, this, pretty flow ; that , a- 
gainft the Order of the figns from Eaft to Weft, this, following 
them, from Weft to Eaft : that, from South to Nortlv/ff/, from 
North to South, as far as it hath been hitherto, that we hear off, 
obferved : that, on the fide oppofite to the Sun, this, on the 
fame fide : that y having been in its Perigee at the time of its Op- 
pofition, this , having been there, out of the time of its Con- 
junction : where he taketh aifo notice, that this Comet differs in 
brightnefs from the other, as well in its Body, which is far more 
vivid and diftinCt, as in its Train, whofe fplendor is much great- 
er, fince it may be feen e'ven with great Tele f copes, which were 
ufelefs in the former, by reafon of its dimnefs. After this he 
defeends to particulars , and informs us , that he began to ob- 
ferve this Comet April the fecond, and continued for fome days 
following, and that as foon as he had made three or four Ob- 
fervations, he refolved to try again an Ephemmdcs ; but thar, 
having no inftruments exaeft enough, and the Comet being in a 
place, deftitute of Stars, and fubjeeft to Refractions, he feared 
to venture too much upon Obfervations fo ncer one another , 
fince in fuch matters a perfect exactnefs is neceflary, and wifii- 
ed to fee fome precedent Obfervations to direct him: which 
having obfained, he thereby verified what he had begun , and 
refolved to carry on his intended Ephemerides, efpecially being 
urged by his Friends, and engaged by his former undertaking, 
thatfo it might not be thought ameer hazard, that made him 
hit in the former ; as alfo, that he might try, whether his Me- 
thod would fucceed as well in flower, as in fwifter Comets, and 
in thole, that are neer the Sun* as in inch as are oppofite there- 
unto, to the end, that men might be advertifed of the determi- 
nation of its life, if it Could not fervebutin certain particular 
Cafes, 
He relateth therefore, that he had fin i fil’d this New Epheme- 
rides April the fixth, and put it prefently to the Prefs • in doing 
of which, he hopes, he hath not difobliged the Publick : feeing 
that, though we fliould loofe the fight of this Star within a few 
days, by reafon ofits approach to the Sun, yet jhaving found , 
that.
