Eolii/ipus, tlie four-toed horse. Restoration Ijy Charles H. Knight. Tlie animals were

 before the mounting of the skeleton for exhibition can l)e commenced. 



As the work of clearing the rock progresses, one point of anatomy will 

 be keenly watched, and that is, whether this earliest known horse possesses 

 the remnant of a fifth toe on the front foot and of the fourth toe on the hind 

 foot. If it does, this places it a decided step nearer to the still earlier but yet 

 undi.scovered ancestor of the horse, which un(li)ul)tedly possessed five toes 

 on both fore and hind feet.
