Iune sustaineth more heate of the Sunne, then Saint Thomas Iland lying
neere the same Meridian doeth likewise at noone, or the Ilands Traprobana,
Molluccæ, or the firme lande of Peru in America, which all lye vnderneath
the Equinoctiall. For vpon the twelfth day of Iune aforesaide, the Sunne
beames at noone doe make an Isoscheles Triangle, whose Vertex is the Center
of the Sunne, the Basis a line extended from Saint Thomas Iland vnder the
Equinoctiall, vnto Paris in France neere the same Meridian: therefore the
two Angles of the Base must needs be equal per 5. primi,[60] Ergo the force
of the heat equal, if there were no other cause then the reason of the
Angle, as the olde Philosophers haue appointed. [Sidenote: In Iune is
greater heat at Paris then vnder the Equinoctiall.] But because at Paris
the Sunne riseth two houres before it riseth to them vnder the
Equinoctiall, and setteth likewise two houres after them, by meanes of the
obliquitie of the Horizon, in which time of the Sunnes presence foure
houres in one place more then the other, it worketh some effect more in one
place then in the other, and being of equall height at noone, it must then
needs follow to be more hote in the Parallel of Paris, then it is vnder the
Equinoctiall.

[Sidenote: The twilights are shorter, and the nights darker vnder the
Equinoctiall then at Paris.] Also this is an other reason, that when the
Sunne setteth to them vnder the Equinoctiall, it goeth very deepe and lowe
vnder their Horizon, almost euen to their Antipodes, whereby their
twilights are very short, and their nights are made very extreeme darke and
long, and so the moysture and coldnesse of the long nights wonderfully
encreaseth, so that at length the Sunne rising can hardly in many houres
consume and driue away the colde humours and moyst vapours of the night
past, which is cleane contrary in the Parallel of Paris: for the Sunne
goeth vnder their Horizon but very little, after a sloping sort, whereby
their nights, are not very darke, but lightsome, as looking into the North
