The uniting or collection of the sun-beams multiplieth heat, as in burning glasses, which are made thinner in the middle than on the sides (as I take it, contrary to spectacles) and the operation of them is, as I remember, first to place them between the sun and the body to be fired, and then to draw them upward towards the sun, which it is true maketh the angle of the cone sharper. But then I take it if the glass had been first placed at the same distance, to which it is after drawn, it would not have had that force, and yet that had been all one to the sharpness of the angle. Qu.
So in that the sun's beams are hotter perpendicularly than obliquely, it may be imputed to the union of the beams, which in case of perpendicularity reflect into the very same lines with the direct, and the further from perpendicularity the more obtuse the angle, and the greater distance between the direct beam and the reflected beam.
The sun-beams raise vapours out of the earth, and when they withdraw they fall back in dews.
The sun-beams do many times scatter the mists which are in the mornings.
The sun-beams cause the divers returns of the herbs, plants and fruits of the earth; for we see in lemon-trees and the like, that there is coming on at once fruit ripe, fruit unripe, and blossoms; which may shew that the plant worketh to put .
forth continually, were it not for the variations of the accesses and recesses of the sun, which call forth, and put back.
The excessive heat of the sun doth wither and destroy vegetable, as well as the cold doth nip and blast them.
The heat or beams of the sun doth take away the smell of flowers, specially such as are of a milder odour.
The beams of the sun do disclose summer flowers, as the pimpernel, marigold, and almost all flowers else, for they close commonly morning and evening, or in over-cast weather, and open in the brightness of the sun; which is but imputed to dryness and moisture, which doth make the beams heavy or erect; and not to any other propriety in the sun-beams: so they report not only a closing, but a bending or inclining in the Heliotropium and Calendula. Qu.
The sun-beams do ripe all fruits, and addeth to them a sweetness or fatness; and yet some sultry hot days overcast, are noted to ripen more than bright days.

The sun causes pestilence, which with us rage about autumn; but it is reported, in Barbary they break up about June, and rage most in the winter.
The heat of the sun, and of fire, and living creatures, agree in some things which pertain to vivification; as the back of a chimney will set forward an apricot-tree as well as the sun; the fire will raise a dead butterfly as well as the sun; and so will the heat of a living creature. The heat of the sun in sand will hatch an egg. Qu.
The heat of the sun in the hottest countries nothing so violent as that of fire, no not scarcely so hot to the sense as that of a living creature.
The sun, a fountain of light as well as heat. The other celestial bodies manifest in light, and yet non constat, whether all borrowed, as in the moon; but obscure in heat.
The southern and western wind with us is the warmest, whereof the one bloweth from the sun, the other from the sea ; the northern and eastern the more cold. Qu. whether in the coast of Florida, or at Brasil, the east wind be not the warmest, and the west the coldest; and so beyond the antarctic Tropic, the southern wind the coldest.
The air useth to be extreme hot before thunders.
The sea and air ambient, appeareth to be hotter than that at land; for in the northern

near land; but Qu. for that may be by reason of the shores and shallows.
The snows dissolve fastest upon the sea-coasts, yet the winds are counted the bitterest from the sea, and such as trees will bend from. Qu.
The streams or clouds of brightness which appear in the firmament, being such through which the stars may be seen, and shoot not, but rest, are signs of heat.
