Veterinary notes for horse owners : a manual of horse medicine and surgery . rare cases, the incisors assume irregular forms even in youngmouths.

The irregularities due to crib-biting have been alluded to onpage 556. BISHOPINa. 753 Bishoping is a fraudulent operation, which consists in giving a false appear-ance of youth to the incisors of an old horse (Fig. 211) byshortening the length of two or more of them and making cavitiesin them to resemble marks. The trick can be easily seenby the absence of enamel round the false marks; by thespaces between the upper and lower incisors, when the jaws arebrought together (Fig. 212); by the shape of the tables; by theshape of the teeth; by the narrowness of the neck of the teeth;and by the marks of the file. 48 754 Fig. 202.—Side view of parrot-mouth (nat, size).
