ITCHINa OF THE EXTEEMITIES. 



A second form, in which Surfeit is manifesed, consists in a 

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

 itself for the most part to the hind extremities ; but 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 will become 

 unnaturally heated, dry, rough, and scurfy ; the hair will also 

 loose its natural polish and softness, and become dry, and 

 instead of laying close to the limb, will project from the 

 surface. In other cases, again, the limbs may exhibit patches 

 which are denuded of hair, while 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 limbs, which, on some occasions, itch most 

 intolerably.
