continuall Spring. Seeing then the middle Zone falleth out so temperate, it
resteth to declare where the hottest part of the world should bee, for we
finde some places more hote then others.

To answere this doubt, reason perswadeth, the hotest place in[61] the world
to bee vnder and about the two Tropikes; for there more then in any other
place doe both the [Sidenote: Greatest heate vnder the Tropicks.] causes of
heate concurre, that is, the perpendicular falling of the Sunne beames, at
right angles, and a greater continuance of the Sunne aboue the Horizon, the
Pole there being eleuated three or foure and twentie degrees. And as before
I concluded, that though the Sunne were perpendicular to them vnder the
Equinoctiall, yet because the same continued but a small time (their dayes
being short, and their nights long) and the speedie departure of the Sunne
from their Zenith, because of the suddeine crossing of the Zodiake with the
Equinoctiall, and that by such continuall course and recourse of hote and
colde, the temperature grew moderate, and very well able to bee endured: so
nowe to them vnder the two Tropikes, the Sunne hauing once by his proper
motion declined twentie degrees from the Equinoctial, beginneth to drawe
neere their Zenith, which may bee (as before) about the eleuenth day of
May, and then beginneth to sende his beames almost at right Angles, about
which time the Sunne entreth into the first degree of Gemini, and with this
almost right Angle the Sunne beames will continue vntill it bee past
Cancer, that is, the space of two moneths euery day at noone, almost
perpendicular ouer their heades, being then the time of Solstitium
Aestiuale: which so long continuance of the Sunne about their Zenith may
cause an extreeme heate (if any be in the world) but of necessitie farre
more heate then can bee vnder the Equinoctiall, where the Sunne hath no
such long abode in the Zenith, but passeth away there hence very quickly.
Also vnder the Tropikes, the day is longer by an houre and a halfe, then it
is vnder the Equinoctiall; wherefore the heate of the Sunne hauing a longer
