ITCHING OF THE EXTREMITIES. 



A second form, in which Surfeit is manifested, consists ia a 

 violent itching of the limbs. This form of the disease confines 

 itself for the most part to the hiud extremities ; occasionally 

 the fore ones are also affected. 



It is the most common to draught horses of the coarse-bred 

 variety. It is known by the animal frequently rubbing one 

 limb against the other ; and so violent is this rubbing at times, 

 that the extremities are frequently lacerated to a very severe 

 extent. Sometimes the patient stamps the ground violently, or 

 rubs one leg against the other, and stamps at the same time. 

 "When the disease is violent, or when it is of long duration, the 

 skin from the hocks down to the hoofs vrill become unnaturally 

 heated, dry, rough, and scurfy. The hair will also lose its 

 natural polish and softness, and become dry ; and, instead of 

 lying close to the limb, will project from the surface. In other 

 cases, again, the limbs may exhibit patches which are denuded 

 of hair, at the same time the skin is deeply fissured, and from 

 these fissures blood sometimes exudes. 



In other cases, particularly when the disease is advanced, a 

 number of hard but small elevations will appear upon the inner 

 surface of the Umbs, which, on some occasions, itch most into- 

 lerably.
