is easy to imagine that if the shoe is badly constructed, oi 
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 thig 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 quittor. 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
