to its posterior surface a ligament which, when sprained 

 and enlarged, constitutes a curb, a condition resulting 

 from the conformation (curby or sickle hocks), or the 

 work performed (in stud males). One of the hock bones, 

 the cuboid, situated on the outer side of the hock, just 

 below the calcis, may be rough, and in such cases may 

 cause the animal to be credited with a spavin or curb, in 

 all such cases the hocks should be carefully compared and 

 coarseness of the bone not mistaken for diseased condi- 

 tions. The joints of the hinge variety between the 

 lower rows of hock bones are not as important, as the 

 motion allowed is not nearly so extensive as in the true 

 hock joint. Below the hock, the bones are arranged in 

 a similar manner to those in the fore limb. Abnormal 

 bony enlargements are sometimes present on the pastern, 

 and are then known as ringbones; splints are rarely 

 present on the hind cannons. 



Location of points or parts in animals. The accompa-

The poll is the space between and just behind the horns 

 of cattle and ears of horses. 



The forehead., that part of the head from the base of

The face (4), that portion between the level of the eyes 

 and the muzzle. 



The muzzle (5) includes the nostrils and the lips, in pigs 

 known as the snout.
