CORNS 151 



certain, because a diseased action is induced ; and 

 to check this is no easy matter after it has contracted 

 the tendency to secrete diseased horn ; for all shoeing 

 produces pressure on the parts. 



The first thing to be done is to ascertain the 

 extent of the corns ; and this can only be effected 

 by paring out the angle between the crust and the 

 bars ; at the same time it will relieve, and to a great 

 extent do away with, what has caused the complaint. 

 This can be best accomplished by the use of a small 

 drawing knife, with which the corn must be pared 

 out to the bottom ; but great care must be exercised 

 not to wound the sole. After this operation, it will 

 be seen whether there is any effusion of blood or 

 matter underneath the corn. If there is reason to 

 believe that such is the case, then an opening must 

 be made through the horn, so that the matter may 

 discharge itself and the separated horn be removed ; 

 and when the course of the sinuses have been ascer- 

 tained, the same remedies must be employed as in 

 quittor. 



In bad cases of corns, where the inflammation 

 has rendered the parts very sensitive, a bar-shoe will 

 be of service, so chambered that there will be no 

 pressure on the part affected. 



If corns have once existed to a considerable extent, 

 they are liable to return ; therefore, before shoeing, 

 the seat of the corn should be well pared out. The 

 seated shoe (which we have described in our chapter 

 on shoeing) should be used, with a web sufficiently 

 thick to cover the situation of the corn, and extend- 

 ing as far back as possible without producing injury 

 to the frog. When the horn has grown to some 

 extent, if the horse is turned out to grass with a 

 bar-shoe in the first instance, and afterwards with a
