I shall expose the third left frontal convolution of the brain through the fronto-parietal bone, and, in making the osteoplastic flap, I intend to leave a wide working margin above the size of the opening which may actually be necessary in order to reach the growth.

When the foot has been subjected to laminitis of some weeks' duration, the same condition is also met with, being at the same time associated with rarefactive osteoplastic ostitis, conditions which we shall shortly describe.

The osteoplastic or condensing process that appears to exist simultaneously with it explains, no doubt, how it is that bones so affected do not more commonly fracture.

The periostitis thus set up invariably takes the osteoplastic form, and as a result of this we have growths of new bone in the near neighbourhood of the joint.

It is in the later stages of the disease—that is, when the pus has been evacuated and reparative changes commenced—that this osteoplastic periostitis is most marked, and it plays a large part in bringing about the condition of anchylosis, which we shall afterwards describe.
