Here the series of these wonderful discoveries was supposed to stop; but by digging in the lowest layers of the same bed (the Eocene) they found the remains of a still older animal of the horse series (the Eo-hippus), which has not only four toes, but a remnant of the first toe, as you can see in Fig. ii. This first toe corresponds to our thumb, showing that the animal came from a five-toed race. This animal was about the size of a very small fox. Probably the whole race of horses is descended from an animal about the size of a rabbit.
