mr Hooke conceiud that the object as the sun moon & c in all posib[ility]
appeard vnder the same angle to the eye but that the Judgemen[t]
of or phansy Imagined it to appear bigger or lesse according
to the Distance that It imagined it to appear at, and therefore

they are painted wth. a faintish blewnesse. soe a man seen
in a fogg appears of a gygantique bignesse because though he
be very neer yet being seen through a thick air the fantcys
Imagines it at a much greater Distance.
