lutely natural: againſt which he objecteth, ſaying, that according
to theſe mens opinion; Si tota terra, unà cum aquâ in nihilum
redigeretur, nulla grando aut pluvia è nube decideret, ſed
raliter tantùm circumferetur, neque ignis ullus, aut igneum

[Which I tranſlate to this ſenſe:] If the whole Earth, together
with the Water were reduced into nothing, no hail or rain would
fall from the clouds, but would be onely naturally carried round;
neither any fire or fiery thing would aſcend, ſeeing to theſe that men
it is no improbable opinion that there is no fire above.
SALV. The providence of this Philoſopher is admirable, and
worthy of great applauſe, for he is not content to provide for
things that might happen, the courſe of Nature continuing, but
will ſhew hic care in what may follow from thoſe things that he
very well knows ſhall never come to paſs.
I will grant him

SIMP. No, he doth not.
SALV. I would give any thing to change a word or two with

ried away with it the common centre of gravity, as I believe it did;
in which caſe, I think that the hail and water would remain
ſate and ſtupid amongſt the clouds, without knowing what to do
with themſelves.
It might be alſo, that attracted by that great
void Vacuum, left by the Earths abſenting, all the ambients would
be rarified, and particularly, the air, which is extreme eaſily drawn,
