tion of the Eye ; or rather the Imagination from the 
Eye. 
For fure it is, that the Imagination doth not eftimats 
the greatneft of the Obje£t feen, only by the Angle which 
it makes at the Eye ; but, by this compared with the fup- 
pofed diftance. 
True it is thatyCatem farihrn^ we judg that to be the 
greater Objeft, which makes at the Eye the greater An- 
gle : But not lb if apprehended at diflPerent Diftances. 
For if through a Cafement f or leffer aperture j we fee 
a Houle at lOo Yards diftance ; this Houfe ( though feen 
under a iefs Angle;jdoth not to us feem lefs than the Cafe- 
ment through which we fee it, ( or this greater than 
that, becaufe it makes at the Eye the greater Angle; J 
But the Imagination makes a comparative Eftimate from 
the Angle and Diftance joyntly confidered. 
So that, of two things feen under the fame or equal 
Angles, if to one of them there be ought which gives the 
apprehenfion of a greater Diftance, that to the Imagina- 
tion will appear greater. 
Now fure it is , that one great advantage for Eftimat- 
ing of a thing feen, is, from the variety of intermediate 
Objefts between the Eye and the thing feen. For then 
the Imagination muft allow room for all thefe things. 
Hence it is that if we fee a thing over twoHills, between 
which there lies a great Vally unfeen^it will appear much 
nearer than if w@ fee the Vally alfb : and it will appear as 
juft beyond the firft Hil). And if we move forward to the 
top of the neareft Hill ( that fb the Vally may be feen ) it 
will then appear much further than before it did. 
And on tins account it is, that the Sun letting, ap- 
pears to us as if it were but jail: beyond the utmoft of 
our vliible Horiz>on \ becaufe all between that and the 
Sun is not feen. And, upon the fame account, the Hea-
