heat is greatest, there is no great collection of clouds, nor an abundant fall of rain, lest disease should be produced among the inhabitants; for watery clouds, if they are acted on by rapid heat, render the air impure and pestilential. And the earth also, receiving the warm rain, does not afford nourishment to the crops, but destruction. In this who can doubt that there is the working of divine providence?

Is it not providence that has ordained that plants, when they decay by old age, should be reproduced by the suckers or the seeds which they have themselves produced, and animals by propagation? And by a certain wonderful dispensation of providence, milk is prepared in the udders of the dams for the
