80 EXAMINATION OF HORSES 
part of the smith when being shod. Pathologically 
regarded, corns, one would think, could be easily re- 
moved ; but such is not the case—plainly showing, to 
my mind, that their terdency to form is very strong in 
such feet as those in which we find them. Let me cau- 
tion you against being satisfied by looking for corns 
on the inner side; the very fact that they do occur on the 
outer heel shows us that we have no more right to pass 
over this than we have to pass over any other point 
because defects found in it are of /ess freguent occurrence. 
We do not pass over unnoticed the hind foot because it* 
is less frequently the seat of disease than the fore foot. 
I mention this because so many persons only search for 
corns in the inner heel and pass over the outer one. 
Whilst you have the shoe off, you can observe better 
than with it on the state of the sole as to its convexity., 
It is astonishing how one may be deceived in this matter 
when the shoe is on, especially if the shoe be rather 
thick. In such cases a somewhat flattened sole may 
appear to be far more concave (arched) than it really is. 
Laminitis, subacute and chronic, I have already told 
you about, and I shall reserve the subject of navicular 
disease till to-morrow.
