its apex. This triangular piece of frog which has been
isolated by the incision is now grasped with the tenaculum
and dissected away. Asa general rule the operator finds
that he has not yet reached the flexor pedis tendon but only
the fatty cushion which covers the latter. The remnants
of the fatty frog should be removed with the double-edged
sage knife or scalpél by means of a horizontal incision, and
there is then seen the greenish or yellowish colored necrotic
flexor pedis tendon, which may at times be covered with

reddish colored granulations. Should the operation be in-
dicated on account of a suppurative pododermatitis the bars
on‘the affected side must be excised along with jthe other
portions. The position and extent of the navicular bone
can be determined by feeling through the flexortendon. A
transverse incision is then made over the middle of the
navicular bone through the flexor pedis tendon into the
navicular bursa, the distal end of the tendon grasped with
