That which occured to my Thoughts upon thefe Con. 
fidcrations, was to this purpofe ; That fome Circum- 
polar Stars (nearer to tne Pole of the Equator than is 
our Zenith, and not far from the* Pole of the Zodiack) 
fhouid be made choice of for this purppfe. And in 
cafe the Meridianal Altitude be difcernably different at 
different times , fo will alio be their utmoft Eaft and 
Weft Azimuth, which may be better obfeivtd than their 
-Rifing or Setting: And this will be not obnoxious to the 
Refradion, as is the Merid.onal Altitude; (for though 
the Refra&ion do affedt the Altitude, yet not the Azi- 
muth ac all) ,• and we may here have choice of Stars for 
the purpofe ; which in Ob&rvations from the bottom of 
a Well we cannot have ; being there confined to thofe 
only which pals very near our Zerinh, though very (mall 
Stars. 
I would then take it for granted, as a thing at leaft 
very probable, that the Fixed Stars are not all (as was 
wont to be fiippofed) at the fame diftance from us • but 
the diftance of fome, vaftly greater than of others; and 
confequently, though as to the more remote , the Parallax 
may be undilcernable ; it may perhaps be difcernable in 
thofe that are nearer to us. 
And thofe we may reafonably guefs (though we are not 
fure of it) to be nearefl to us, which to us do appear 
biggeft and brighteft, a? are thofe of the Firft and Se- 
cond Magnitude ; and there are at leaft of the Second 
Magnitude, pretty many not far from the Pole of the 
. . 'Echptick, (as that in, particular, in the Shoulder of the 
-leffer Bear) : And in -cafe we fail in one, we may try a- 
gain and again on fome other ; which may chance to 
be nearer to us than what we try firft. And Stars of 
this bignefi may be difcerned by a moderate Telefcope, , 
even in the day-time efpecialiy when we know juft 
where to look for them.
