is easy to imagine that if the shoe is badly constructecl, or 

 allowed to remain too long on, that corns must be induced. 

 This effect will be rendered manifest by an attentive obser- 

 vation of the foot in plate 6, fig. 10. When paring is 

 not attended to in shoeing, or when it is injudiciously 

 extended to the bars, the evil of corns is likely to arise. 

 This unnatural pressure of the sole causes the blood to 

 be thrown out, which enters into the pores of the soft 

 and diseased horn which is then secreted ; and by the colour 

 and softness of the horn at this place, the existence and 

 extent of the corn is judged. 



Remedies. — The cure of corns is difficult and uncertain, 

 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 ascertained, the same remedies must 

 be employed as in quitter. If there should happen to 

 be no collection of matter, the chloride of antimony should 

 be applied over the whole extent of the corn after the horn
