will suffice; but where the sprain is severe and the enlargement con- 

 siderable, a blister will afterwards require to be applied to the leg between 

 the knee and the fetlock, and repeated once or oftener according to the 

 progress of the case. It often happens that the 

 shortest way to a cure is to fire the part as soon 

 as the inflammation has dispersed, and blister over 

 the fired surface. 



In bad sprains there is a tendency to contraction and 

 shortening of the injured tendon, resulting in "knuck- 

 ling over" of the fetlock -joint. To guard against 

 this the wedge-heeled shoe should not be worn too 

 long, but gradually reduced in thickness until the 

 heel is brought to a level bearing with the parts in 

 front. If in spite of this the tendon should contract 

 unduly, a shoe having a short lever projecting from the toe (fig. 380), and 

 a low, thin heel, must be adjusted to the foot and worn for a few weeks. 

 If this foil, then the shortened tendon may require to be cut through in 

 order that the parts displaced may resume their normal position.

WIND-GALLS 



These are small, rounded, fluctuating enlargements occurring in the 

 neighbourhood of joints, more especially on the outer and inner aspects of 

 the fetlocks, and also on the 

 hocks and knees (fig. 381). 

 AVind- galls are divided into 

 two classes, according to the 

 part they implicate. In one 

 case they result from a drop- 

 sical and unduly distended 

 state of the capsular mem- 

 brane of the joint with syno- 

 via, when they are known as 

 "articular wind-galls". In 

 the other they are due to a 

 similar state of distension of 

 the synovial sheath of a 

 tendon, as in thoroughpin. 



They appear either as 

 isolated swellings or in rows of two or three. To the uninitiated it 

 might appear that each of the wind -galls observed about the fetlock -
