Chapter Xii. of the Inclination of the Earth.

Leucippus affirms that the earth vergeth towards the southern parts, by reason of the thinness and fineness that is in the south; the northern parts are more compacted, they being congealed by a rigorous cold, but those parts of the world that are opposite are enfired. Democritus, because, the southern parts of the air being the weaker, the earth as it enlarges bends towards the south; the northern parts are of an unequal, the southern of an equal temperament; and this is the reason that the earth bends towards those parts where the earth is laden with fruits and its own increase.
