The horny box or hoof consists of wall and bars, sole and frog.

This, of course, entirely alters the contour of the horny box.

That condition, however, is entirely dependent upon the changes occurring within the horny box.

It is the function of this tendon to flex the coffin bone and, with it, the horny box.

As time goes on the sensitive structures accommodate themselves to the altered form and conditions of the horny box.

As a matter of fact, we find one case on record where one-half of the horny box was thus removed.

The coffin bone forms the end of the foot and is shaped like the horny box in which it is inclosed.

The loss of adhesion between the pedal bone and the horny box, which we know to be then existent, negatives its advisability.
