he contrary motion of the earth hee
will gaine ground. But experience hath proued this to bee false,
shewing that the bullets, will both fly at equall distance.

To salue this, answere is made that the earth by its swift motion
carries with it and that steadily not only all bodies resting or
moueing vpon it, but also the whole Sphaere of Aire (_WEQ_) with
all things whatsoeuer that are moued in it naturally or
violently, as clouds, birds, stones hurled vp or downe, arrowes,
bullets, and such like things violently shott forth: as may
appeare in the figure.

The fourth rule.

4 The earth, though it bee of exceeding greate quantity being
considered in itselfe, yet being compared to the Heauens,
especially the higher sphaeres, is of noe notable bignes, but may
be accounted as a point or pricke in the middest of the world.

That the earth is noe bigger then a point or pinns head in
comparison of the highest heauens will easily appeare vnto vs, by
these reasons.

1 The starres which are many times bigger then the earth, seeme
yet to vs to bee noe bigger then a greate pinns head, or such
like quantity; therefore much lesse shall the earth appeare to
bee of any sensible magnitude.

2 Wee alwaies beholde halfe the heauens aboue vs, which could not
bee if the earth had any sensible proportion to the heauen.

3 All obseruations of hights and distances of the coelestiall
bodies, which are made on the superficies of the earth, are as
exact, and true, as if they were made in the very center of the
earth. Which were impossible, vnlesse the thicknes of the earth
were insensible in regard of the Heauens.

4 All Sunn Dialls which stand on the superficies of the earth,
doe as truely cast the shadowes of the houres, as if they stood
in the Center. As for example.

The starre (_S_) appeares like a point or pricke to them that
dwell in (_A_) wherefore the earth (_OX_) will appeare much lesse
to the sight of him that should behold it from (_S_), nay it
would not bee seene at all. Againe halfe the Heauens (_BFE_) are
alwayes seene to th[~e] that dwell in (_A_) wanting some two
minutes, betweene (_ED_) and (_BC_) which difference is
alltogether insensible. Againe if wee obserue the height of the
starre (_S_) aboue the Horizon (_BE_) it will bee all one namely
(_BS_) whether wee obserue it in the topp of the earth, in (_A_)
or in the middle in (_O_.) For, (_A_) and (_O_,) are so little
distant one from another, that (_AS_,) and (_O
