    *The incisors or front teeth in the horse are 12 in number, 6 in each jaw; the upper ones are the longest, their surfaces meeting those of the lower ones; in rare cases the former overlap, constituting a parrot mouth. The central pair are the largest, the adjacent ones are called the middle, or lateral, while the outer ones which are the smallest are termed the corner incisors. [In Ruminants which have 8 incisors, the first pair are called centrals; the second FIG. 5.

The row of incis- ors form a curve, which is part of the so-called den- tal arch; the younger the tooth the greater the curva- ture, which gradully decreases with age. The anter- ior surface of a young incisor tooth presents a trian- gular shape, with the base at the table. Viewed laterally it is still triangular, but its apex is at the table. The table is therefore oblong, its long axis ♦Strangeway.
