midable affection known as morbus cosarius, or liipjoint disease; and 

 leaving the detail of other lesions to take their place under other heads, 

 that relating to the shoulder, for instance, we turn to the hip joint and 

 its ailments as the chief subject of our present consideration. 



In investigating for morbus coxarius, let the observer first examine 

 the lame animal by scanning critically the outlines of the joint and the 

 region adjacent for auj difference of size or disturbance of symmetry 

 in the parts, any prominence or rotundity, and on both sides. The 

 lame side will probably be warmer, more develoi^ed and fuller, both to 

 the touch and to the eye. Let him then grasp the lower part of the 

 leg (as he would in examining a case of shoulder lameness), and en- 

 deavor to produce excessive i3assive motion. Tliis will probably cause 

 pain when the leg is made to assume a given position. Let him push 

 the thigh forcibly against the hip bone, and the contact will again prob- 

 ably cause a manifestation of x^ain. If the horse is trotted, the limited 

 action of the hip joint proper and the excessive dropping and rising of 

 the hip of the opposite side will be easily recognized. The abductivo 

 or circumflex motion observed in shoulder lameness is also present in 

 hip lameness, but under special conditions, and the test of the difficulty, 

 either by traveling on soft ground or making the lame leg a pivot in 

 turning the horse in a circle, may here also contribute to the diagnosis 

 as in testing for lameness in the anterior extremity. 



The prognosis of hip lameness is at times quite serious, not only 

 on account of the long duration of treatment required to effect good 

 results, and because of the characters which may be assumed by the 

 disease, but of the permanence of the disabihty resulting from it. Ex- 

 ostosis and ulcerative arthritis arc sequela) which often resist every 

 form of treatment. 



As before intimated, this is little more than a repetition of our 

 remarks upon the lameness of the shoulder, with slight modifications 

 occasioned by the muscular structure of the hip, and we are limited to 

 the same recommendations of treatment. The advantages of rest must 

 be reaffirmed with local applications, of which, however, it may be said 

 that they are more distinctly indicated and likely to be more effective 

 in their results than in shoulder lameness, and may be more freely em- 

 ployed, whether in the form of liniments, blisters (singly or repeated), 

 firing, or setoning. 



Sprains of susj)cnsory ligaments and of the flexor tendons or their sheath. — 

 The fibrous structure situated behind the cannon bones, both in the fore 

 and hind legs, is often the seat of lacerations or sprains resulting from 

 violent efforts or sudden jerks. The injury is readily recognized by the 

 changed aspect of the region and the accompanying local symptoms. 

 The parts, which in health are well defined, with the outlines of the 

 tendons and ligaments well marked, become the seat of a swelling, 

 more or less developed, from a small spot of the middle of the back of 

 the tendon to a tumefaction reaching from the knee down to and even
