What and how various are the kinds of animals, tame or wild? The flights and notes of birds? How do the beasts live in the fields and in the forests? What shall I say of men, who, being appointed, as we may say, to cultivate the earth, do not suffer its fertility to be choked with weeds, nor the ferocity of beasts to make it desolate; who, by the houses and cities which they build, adorn the fields, the isles, and the shores? If we could view these objects with the naked eye, as we can by the contemplation of the mind, nobody, at such a sight, would doubt there was a divine intelligence.

- ↑ These two contrary reversions are from the tropics of Cancer and Capricorn. They are the extreme bounds of the sun's course. The reader must observe that the astronomical parts of this book are intro-
