orbitular

Updated: May 3, 2025

The 200,000 years for the ice-age depends chiefly on Croll's theory of secular variation of the earth's orbitular eccentricity; but we are told it is open to the "objection that it requires us to assume a periodical succession of glacial epochs" of which two or three "must have occurred during each of the great geological epochs. This is opposed to geological evidence."
