It may be objected that Elephas primigenius is absolutely distinct from E. Indicus. I answer, Yes, specifically distinct; and so am I distinct from my father,—individually distinct. But as individual distinctness does not preclude the individual from being the exponent of a circular revolution in the life-history of the species, so specific distinctness may not preclude the species from being the exponent of a circular revolution in some higher, unnamed, life-history.
