strong solution of carbolic acid — 1 to 4 — should be used at first. Or, 

 strong solutions of tincture of iodine, sulphate of iron, sulphate of cop- 

 per, bichloride of mercury, etc., may be used in place of the carbolic; 

 after which the remedies and dressings, directed for use in simple quit- 

 tor, are to be used. In those cases where the fistulous tracts refuse to 

 heal, it is often necessary to burn them out with a saturated solution 

 of caustic soda, equal parts of muriatic acid and water, or, better still, 

 with along, thin iron, heated white hot. 



But no matter what treatment is adopted, a large percentage of the 

 cases of tendinous quittor fail to make good recoveries. Where the 

 entire hoof sloughs away, the growth of a new, but soft and imperfect, 

 hoof may be secured by carefully protecting the soft and exposed tis- 

 sues with proper bandages. When the joints are opened by deep 

 sloughing, recovery may eventually take place, but the joint remains 

 immovable ever after. If caries of a small part of the cofiin bone takes 

 place, it may be removed by an operation ; but if much of the bone is 

 affected, or if the navicular and coronet bones are involved in the cari- 

 ous process, the only hope for a cure is in the amputation of the foot. 

 Of course, this operation would only be advisable where the animal was 

 valuable for breeding purposes. In all other cases where there is no 

 hope for recovery the patient's suffering should be relieved by death. 

 In tendinous quittor much thickening of the coronary region, and some- 

 times of the ankle and fetlock, remains after suppuration has ceased 

 and the fistulous tracts have healed. To stimulate the reabsorption of 

 tliis new and unnecessary tissue the parts should be fired with the hot 

 iron ; or, in its absence, repeated blistering, with the biniodide of mer- 

 cury ointment, may largely accomplish the same result. 



SUBHORXY QUITTOR. 



This is the mostcommon form of the disease. It is generally seen in but 

 one foot at a time, and more often in the fore feet than in the hind ones. 

 It nearly always attacks the inside quarter, but may affect the outside 

 quarter, the toe or the heel, where it is but of little consequence. It 

 consists in the inflammation of a small part of the coronary baud and 

 adjacent skin, followed by sloughing and more or less suppuration, 

 which in most cases extends to the neighboring sensitive laminae. 



Causes. — Injuries to the coronet, such as bruises, overreaching, and 

 calk wounds, are considered as the common causes of this disease. 

 Still, cases occur in which there appears to be no exciting cause, just as 

 in the other forms of quittor, and it seems fair to conclude that sub- 

 horny quittor may also be produced by internal causes. 



S>jm2)toms. — At the outset the lameness is always severe, and the 

 patient often refuses to use the affected foot. Swelling of the cor- 

 onet takes place close to the top of the hoof, causing the quarter 

 to protrude beyond the wall of the foot. This tumor is extremely
