suppuration of the sj'uovial sacs and joints, thereby converting a 

 simple quittor into one which will, in all probabilit}^, either destroy 

 the patient's life or inaini him for all time. 



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

 influences that produce the sinqile 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 satisfied that young 

 animals are more liable to have tendinous quittor than older ones, 

 and that thej^ are much more likely to make a good recovery. 



Sumptoms. — When a case of simijle quittor is transformed into the 

 tendinous variety the development of the complications is announced 

 by a sudden increase in the severity' of all of the symptoms. On the 

 other hand, if the attack primarily is one of tendinous quittor, the 

 earliest symj)tom seen is a well-marked lameness in the affected leg. 

 In those cases due to causes other than injuries this lameness is at 

 first very slight, and the animal limps no more in trotting than in 

 walking; but later on, generally during the next forty-eight hours, 

 the lameness increases to such an 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 so 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 symi)toms increase in intensity; 

 the pulse is rapid and hard, the breathing quick, the temperature 

 elevated three or four degrees, the appetite is gone, thirst is increased, 

 and the lameness is so great that the foot is carried in the air if loco- 

 motion is attempted. At this stage of the disease the patient gener- 

 ally seeks relief by lying upon the broad side, with outstretched legs, 

 the coat bedewed with a clammy sweat, Avhile every respiration is 

 accompanied by a moan. The leg soon swells to the fetlock; later 

 this swelling gradually extends as high as to the knee or hock, and 

 in some cases it even reaches the body. As a rule several days elapse 

 before the disease develoi)s a well defined abscess, for, owing to the 

 dense structure of the bones, ligaments, and tendons, the suppurative 

 pi'ocess is a slow one, and the pus when formed is prevented from 

 readily collecting in a mass. 



Recently I made a post mortem examination on a typical case of 

 this disease, Avhere the animal had died on the fourth day after being 

 found on the range slightly lame. The suffering had been intense; 

 yet the only external evidences of the disease consisted in the shed- 

 ding of the hoof from the right fore foot, and a limited swelling of 

 the leg to the knee. The sloughing of the hoof took place two or three 

 hours before death, and was accompanied with but little suppuration
