in a cleare night without cloudes it doeth manifestly appeare, their
twilights are long: for the Parallel of Cancer cutteth not the Horizon of
Paris at right Angles, but at Angles very vneuen, and vnlike as it doeth
the Horizon of the Equinoctiall. Also the Sommer day at Paris is sixteene
houres long, and the night but eight: where contrarywise vnder the
Equinoctiall the day is but twelue houres long, and so long is also the
night, in whatsoeuer Parallel the Sunne be: and therefore looke what oddes
and difference of proportion there is betweene the Sunnes abode aboue the
Horizon in Paris, and the abode it hath vnder the Equinoctiall, (it being
in Cancer) the same proportion would seeme to be betweene the heate of the
one place, and heate of the other: for other things (as the Angle of the
whole arke of the Sunnes progresse that day in both places) are equall.

But vnder the Equinoctiall the presence and abode of the Sunne aboue the
Horizon is equall to his absence, and abode vnder the Horizon, eche being
twelue houres. And at Paris the continuance and abode of the Sunne is aboue
the Horizon sixteene houres long, and but eight houres absence, which
proportion is double, from which if the proportion of the equalitie be
subtracted to finde the difference, there will remaine still a double
proportion, whereby it seemeth to follow, that in Iune the heate of Paris
were double to the heate vnder the equinoctiall. For (as I haue said) the
Angles of the Sunne beames are in all points equall, and the cause of
difference is, Mora Solis supra Horizontem, the stay of the Sunne in the
one Horizon more then in the other. [Sidenote: In what proportion the Angle
of the Sun beames heateth.] Therefore, whosoeuer could finde out in what
proportion the Angle of the Sunne beames heateth, and what encrease the
Sunnes continuance doeth adde thereunto, it might expresly be set downe,
what force of heat and cold is in all regions.
