These are the vitals of the theory, and the primary assertions, whereof I do freely profess my full belief; and whosoever by solid reasons will show me an error and undeceive me, I shall be very much obliged to him. There are other lesser conclusions which flow from these, and may be called secondary, as that the longevity of the Antediluvians depended upon their perpetual equinox and the perpetual equality and serenity of the air; that the torrid zone in the primitive earth was uninhabitable, and that all their rivers flowed from the extreme parts of the earth towards the equinoctial, there being neither rain nor rainbow in the temperate and habitable regions of it; and lastly, that the place of Paradise, according to the opinion of antiquity (for I determine no place by the theory) was in the southern hemisphere. These, I think, are all truly deduced and proved in their several ways, though they be not such essential parts of the theory as the former. 2
