If the expectation raised by the splints of the Horses that, in some ancestor of the Horses, these splints would be found to be complete digits, has been verified, we are furnished with very strong reasons for looking for a no less complete verification of the expectation that the three-toed. Plagiolophus-like "avus" of the horse must have had a five-toed "atavus" at some earlier period.
No such five-toed "atavus," however, has yet made its appearance among the few middle and older Eocene Mammalia which are known.

To that tendency a special name is given and as I may very often use it, I will write it up here on this black-board that you may remember it it is called Atavism; it expresses this tendency to revert to the ancestral type, and comes from the Latin word atavus, ancestor.
