hoof-wall, which in its turn may press on the quick and 

 cause lameness. With or without any remains of sand- 

 crack there is tenderness on pinching that part of the 

 hoof, and when the shoe is removed and the hoof pared, 

 there is observed a semicircular encroachment on the sola 

 by a white spongy horn extending in from the hoof-walL 

 Wet swabs on the foot and rest may subdue any inflam' 

 mation, but should lameness persist, the only resort is to 

 cut out a triangular portion of the wall including the tu- 

 mor, poultice the part, then cover with tar and wait for 

 the horn to grow down in a healthy condition. 



COENS. 



These are at first simple bruises of that part of the sole 

 included between the bars and the wall at the heel, but 

 later there is often an increased production of horn and 

 the formation of a horny tumor which presses injuriously 

 on the quick. In other cases the bruise causes active 

 inflammation and the formation of matter, which if denied 

 escape below, wiU burrow toward the coronet or less fre- 

 quently around the toe and give rise to disease in the 

 deeper fibrous network, the cartilage or the bone. In 

 these last conditions it usually results in a fistula (quitter). 

 In other cases thd corn is pared out as is supposed, but 

 the heels, having lost the mechanical sufport of the sole, 

 curl forward and inward, repeat the bruise continually, 

 keep up the inflammation and suppuration and what is 

 equivalent to an open sore in the heel. The irritation 

 often produces absorption of the margin of the bone at 

 the heels with bony deposits above or below, and ossifica- 

 tion of the lateral cartilage, a condition which almost 

 necessarily perpetuates the bruises or corns (see side bones). 

 Corns may exist in either heel but are usually in the inner 

 or weaker one, and prevail above all in flat feet with low 

 weak heels. 



Symptoms. Lameness with a tendency io point, with the 

 heel slightly raised when at rest, and a short, stilty, stum-
