accuracy, it follows that an object brought close to the eye is not
at a due distance, but is too near for the central line to be able
to discern the outlines of the object. So the edges fall within the
lines of weaker discerning power, and these are to the function of
the eye like dogs in the chase which can put up the game but cannot
take it. Thus these cannot take in the objects, but induce the
central line of sight to turn upon them, when they have put them up.
Hence the objects which are seen with these lines of sight have
confused outlines.
The relative size of objects with regard to their distance from the
eye (93-98).

3.
PERSPECTIVE.
Small objects close at hand and large ones at a distance, being seen
within equal angles, will appear of the same size.

4.
PERSPECTIVE.
There is no object so large but that at a great distance from the
eye it does not appear smaller than a smaller object near.
