And though the followers of Ptolomy, do
with much confidence deny the Heavens to
be capable of any reluctancy to motion;
yet it were eaſy to prove the contraby, out
of their own Principles. ’Tis not conceiv-

the nether, unleſs their Superficies were full
of rugged parts, ( which they deny:) or
elſe one of the Orbs muſt lean upon the o-
ther with its weight, and ſo makeit partake
of its own Motion. And beſides, they tell us,
that the farther any Sphere is diſtant from
the Primum Mobile, the leſs is it hindred by
that in its proper courſe, and the ſooner
does it ſiniſh its own Revolution. From
whence it will eaſily follow, that theſe Bo-
dies have reſiſtancy from one another.

I have often wondred, why amongſt the
inchanted Buildings of the Poets, they have
not fained any Caſtle to be made of the ſame
Materials with the ſolid Orbs, ſince in ſuch a
Fabrick, there would have been theſe emi-
