hispection. — In rupture of the perforatus tendon there is 

 supporting-leg lameness, with some dorsal flexion of the 

 phalanges, in conse(]uence of which the toe is turned up a 

 little, and the weight is mainly sustained by the heels. 

 When the perforans is ruptured all three phalangeal joints 

 show decided dorsal flexion, causing the hoofs to rest upon 

 the heels entirely, with the toes elevated from the ground.
