Mr. Croll believes that, owing to variations in the eccentricity of the earth's orbit "cold periods regularly recur every ten or fifteen thousand years; but that at much longer intervals the cold, owing to certain contingencies, is extremely severe, and lasts for a great length of time; and the last great glacial period occurred about two hundred and forty thousand years ago, and endured with slight alterations of climate for about one hundred and sixty thousand years."--Darwin's _Origin of Species_, p. 343.
