who have pretended to deduce it from their Obfervati- 
ons. I believe, that I may venture to fay, that in 
either of the two Stars lad mentioned, it does not 
amount to 2". I am of Opinion, that if it were 1", I 
fhould have perceived it, in the great number of Ob- 
fervations that I made.efpecially of y c Draconts ; which 
agreeing with the Hypothecs (without allowing any 
thing for Parallax) nearly as well when the Sun 
was in Conjunction with, as in Oppofttion to, this 
Star, it feems very probable that the Parallax of it 
is not fo great as one frngle Second ; and conlequent- 
ly that it is above 400000 times farther from us than 
the Sun. 
There appearing therefore after all, no fenfible 
Parallax in the fixt Stars, the Anti-Copernicans have 
frill room on that Account, to objeCt againfr: the Mo- 
tion of the Earth ; and they may have (if they pleafe) 
a much greater Objection againfr; the Hypothefis, 
by which I have endeavoured to folve the fore-men- 
tioned Thanomena ; by denying the progrefrive Mo- 
tion of Light, as well as that of the Earth. 
But as I do not apprehend, that cither of thefe Po- 
frulates will be denied me by the Generality of the 
Aftronomers and Philofophers of the prefent Age; 
fo I ihall not doubt of obtaining their Aflent to the 
Conlequences, which I have deduced from them j if 
they are fuch as have the Approbation of fo great 
a Judge of them as yourfelf. I am, 
Sir, Tour moft Obedient
