DISEASES OF THE FETLOCK, ANKLE, AND FOOT. 411 



the less often the wound is disturbed, the better, so long as the healing 

 process is healthy. When the sore commences to "skin over," the 

 edges should be lightly touched with lunar caustic at each dressing. 

 The patient may now be given a little exercise daily, but the bandages 

 must be kept on until the wound is entirely healed. 



TENDINOUS QurrroR. 



This form of quittor differs from the cutaneous in that it not only 

 affects the skin and subcutaneous tissues, but involves also the ten- 

 dons of the leg, the ligaments of the joints, and, in many cases, the 

 bones of the foot as well. 



Fortunately, this form of quittor is less common than the preced- 

 ing, yet any case beginning as simple cutaneous quittor may at any 

 time during its course become complicated by the death of some part 

 of the tendons, by gangrene of the ligaments, sloughing of the coro- 

 nary band, caries of the bones, or inflammation and suppuration of 

 the synovial sacs and joints, thereby converting a simple quittor into 

 one which will, in all probability, either destroy the patient's life or 

 maim him for all time. 



Causes. — ^Tendinous quittor is caused by the same injuries and 

 influences that produce the simple form. Zundel believes it to be a 

 not infrequent accompaniment of distemper. In my own experience 

 I have seen nothing to verify this belief, but I am convinced that 

 young animals are more liable to have tendinous quittor than older 

 ones, and that they are much more likely to make a good recovery. 



Symptoms. — ^When a case of simple quittor is transformed into the 

 tendinous variety the change is announced by a sudden increase in 

 the severity of all the symptoms. On the other hand, if the attack 

 primarily is one of tendinous quittor, the earliest symptom seen is a 

 well-marked lameness. In those cases due to causes other than inju- 

 ries this lameness is at first very slight, and the animal limps no 

 more in trotting than in walking ; later on, generally during the next 

 48 hours, the lameness increases to such extent that the patient often 

 refuses to use the leg at all. An examination made during the first 

 two days rarely discloses any cause for this lameness ; it may not be 

 possible even to say with certainty that the foot is the seat of the 

 trouble. On the third or fourth day, sometimes as late as the fifth, 

 a doughy-feeling tumor will be found forming on the heel or quarter. 

 This tumor grows rapidly, feels hot to the touch, and is extremely 

 painful. As the tumor develops, all the other symptoms increase in 

 intensity ; the pulse is rapid and hard ; the breathing quick ; the 

 temperature elevated 3° or 4° ; the appetite is gone; thirst increased; 

 and the lameness so great that the foot is carried if locomotion is 

 attempted. At this stage of the disease the patient generally seeks 

 relief by lying upon the broad side, with outstretched legs ; the coat
