In reference to their structure and arrangement, also as a means of ascertaining the animal's age, more accurately at least than by any other method, the teeth of the horse are peculiarly interesting.

In the chapter on the horse of the present day and its fossil progenitors, referring to the peculiar features in the conformation of the horse, the special characters of the teeth will be described, and their relation to the same organs in the earlier types of horse-like animal commented on.

For the present purpose it will only be required that the characters of the different descriptions of teeth, and the changes which they undergo in consequence of the wear to which they are subjected, should be noted sufficiently to enable the horseman to form some opinion as to the animal's age.
