But now when the Diftance grows fb great, as that the 
'Pofition of thefe vifual Axes become Parallel, or C) near 
to Parallel, as not to be diftinguifhable from it : This ad- 
vantage is loft, and we can thenceforth only conclude, 
that it is far off ; but not how far. 
Hence it is, that our view can make no diftinction of 
the Moons Diftance, from that of the other Planets, or 
even of the fixed Stars : But they feem to us as equally 
remote from us ; though we otherwife know their Di- 
ftances from us to be vaftly different. Becaufe the Paral- 
lax ( as I may fb call it ) from the different Pofition of the 
two Eyes, is quite loft, and undifcernable, in Diftances 
much lefs than the leaft of thele. 
And fo , of the fixed Stars amongft themfelves : Which, 
though they feem equally remote from us; many (.{or 
ought we know ) be at Diftances vaftly different. Nor 
can we tell, which of them is neareft : ( unlefs perhaps 
we may reafbnably gueft, thofe to be neareft, which 
feem biggeft. ) Becaufe , here not only the Parallax ^ 
from the Diftance of the two Eyes ; and that from the ' 
Earths Semidiameter ; but even that from the Semidia- 
meter of the Earths great Orb, is quite loft ; and none 
remaining^ whereby to eftimate their Diftance from us. 
But ( to return to our cafe in hand ; ) though as to 
finall Diftances, we may make fbme eftimate from the 
known ik^2g;^/W^ of the Objeft: And, as to middling di« 
ftances, from the Parallax if as I may call it ) arifing from 
the interval of the two Eyes ; Yet even this latter will 
hardly reach beyond, if fb far as the vifible Horiz>on: and 
all beyond it, is loft. - 
So that, there befng nothing left toaflift the fancy la 
cftimating fb great adiitance, but only the intermediate 
Objeds; Where thele intermediates appear to the Eye, 
( as, when the Sun or Moon are near the Horizon : J the 
diftance is fanfied greater, than where they appear not, 
(as when farther from it: ) and confequently though
