412 THE HORSE OF' ANAU IN ITS VARIOUS RELATIONS.
The molars both of the Anau horse and of the other subfossil horses are represented by hundreds, but a detailed study of them can be of use only when we possess sets of teeth which surely belong together, as we fortunately have in a complete half of a palate from Anau.
After what has been said in reviewing the specific characteristics of ass and horse, it is superfluous to follow the course of each enamel plication. Here we will notice the principal differences; as regards the masticating surface the accompanying drawings (fig. 491) will speak for themselves. Nehring and later Salenski affirm that the relations assumed by Frank, for the Oriental and Occidental horses, between length and breadth of masticating surface (teeth broader than long in the Oriental, and longer than broad in the Occidental horse) are not decisive; indeed this relation is greatly influenced by the age of the animal, since through progressive grinding off of the teeth these become smaller towards the roots, and the row of teeth shortens. Nevertheless a comparative tabulation of the size-relations of the whole row of teeth is probably worth making.
