these little burscc mucosoi become injiu'ed, infiammation is set up, 

 and they become permanently enlarged. 



Again, the exertion may bo so violent as to cause sprain of the 

 tendon, which extends to the capsule, or the joint itself may suffer, 

 and cause distension of the capsular ligament constituting compli- 

 cated wind-gall, which is more serious. 



Symptoms. — Simple wind-galls are little puffy swellings, sSen 

 at the sides of the tendons as they pass over the fetlock-joint, 

 most common on the hind leg. They are soft even when the 

 weight is thrown on them. It is very important to be able to 

 distinguish between simple and complicated, or between the harm-

 and the suspensory ligament, it depends on distension of the 

 bursse through which the tendon passes ; if it feels hard when the 

 other leg is held up, and is accompanied with slight lameness, the 

 tendon is implicated. When placed in front of the suspensory 

 ligament, between it and the bone, it is accompanied with increase 

 of synovia in the joint itself. 



Wind-galls generally appear suddenly. 



Treatment. — There are three methods of treatment: First. 

 During the acute stiage they can be easily removed by any firm 

 but even pressure by pads and bandages, with cold water fre- 

 quently applied. 



Second. When it has been long neglected, or the case is com-
