By this Figure we may observe, that any Rays of the Sun A, which fall upon a Place situated ten Degrees on our Side of the Pole B, and Rays which fall on the Pole itself, do not make so large an Angle, as they would if the Form of the Earth was a Sphere; for if we extend the two Points B and C so far as to make a compleat Sphere, we must be obliged
likewise to move the Line D along with it to the Point E, which would make a larger Angle, and in that Case the Surface of the Earth at the Pole B would be more inclined to the Plain of the Ecliptic than it is, and consequently it would be colder, as the Cause of Heat and Cold in different Parts of the Globe is owing to the Inclination of the Poles to the Plain of the Ecliptic, and not to the Distance of the Sun from the Earth at the different Seasons of the Year; for if that was the Case, we should have colder Weather in July than we have in December, the Sun being rather nearer to us in Winter than in Summer.
I hope that this little Philosophical Effort, which has been made here, will not be looked upon as unseasonably introduced in this Place; and I likewise hope, that while I gaze with Wonder on the stupendous Frame of the Universe, I shall not be thought presumptuous in having taken a little Survey of one of the Wheels which duly performs it's
Revolutions in that glorious Machine, the Solar System; the exact and regular Movements of which inspire the curious Beholder with a more awful Idea of the Greatness of the Fabricator, than it is possible for any one to conceive, who is entirely ignorant of the Accuracy of the Construction.

That the more Hay is dried in the Sun, the better it will be.
As Hay is an Herb which is dried in order to lay up all the Winter, when it cannot be found in the Fields, and as it is intended for the Food and Nourishment of Animals, that Nourishment must consist of such of the Juices as are left behind in the Herb.
It is very possible, by the Art of Chemistry, to extract from Hay all the separate Salts, Spirits, &c. of which it is composed. Now in a Chymical Preparation,
