From the perioplic ring the cushion is separated by a narrow and shallow, though well-marked, groove.

_The Superior Border_ follows closely the line marked by the perioplic ring and the groove separating the latter from the coronary cushion.

The perioplic ring has become obliterated, and the varnish-like appearance of the healthy wall destroyed.

The papillæ of the coronary cushion secrete the horn tubules forming the wall, and the papillæ of the perioplic ring secrete the varnish-like veneer of thin horn covering the outside surface of the hoof.

They may, in fact, be first observed as a fine separation of the horn fibres immediately beneath the perioplic covering.

It is, in reality, a thin pellicle of semi-transparent horn secreted by the cells of the perioplic ring.

It extends from the inner to the outer bulbs of the plantar cushion, and is bounded above by the perioplic ring, and below by the laminæ.

This band produces the perioplic horn, the thin varnishlike layer of glistening horn, which forms the surface of the wall or "crust," and whose purpose seems to be to retard evaporation of moisture from the wall.

There are five parts of the pododerm, easily distinguishable when the hoof has been removed, namely: (1) The perioplic band, a narrow ridge from one-sixteenth to one-eighth of an inch wide, running along the edge of the hair from one heel around the toe to the other.
