that the granulating process of repair is always more
rapid upon the plantar cushion and fleshy sole than upon the bone, or upon
tendinous or cartilaginous structures. As a result of this we have a wound
showing various aspects of cicatrization. Healthy granulation may be
profuse in one spot, while in another it may be checked either by a flow
of synovia from the still open bursa, or by fragments of bone or of tendon
still acting as foreign bodies in the wound. These latter may be readily
detected by their standing out as dark and uncovered spots in the healthy
granulation around, and should be at once removed.

The time that an operation wound of this description takes to heal--and
that without complication--is from one to two or three months. Continuation
of pain and intensity of lameness are not to be taken as indications of
failure. The reparative inflammation in the synovial membrane is quite
sufficient to induce pain severe enough to prevent the animal from placing
his foot to the ground for some weeks, even though the progress of the
case, all unknown, may be all that is desired. So long as a great amount of
pain is absent, and so long as appetite remains and swellings in the hollow
of the heel fail to make their appearance, so long may the progress of the
case be deemed satisfactory.

_Recorded Case of the Treatment_.--A cart-horse, aged six years, was sent
to the Alfort School by a veterinary surgeon for having picked up a nail
in the hind-foot. Professor Cadiot, judging the necessity for the complete
operation, performed it on January 14, and spared the plantar cushion
as much as possible. In consequence of the plantar aponeurosis being
extensively necrosed, it was advisable to scrape the navicular bone and
a part of the semilunar crest. The wound having been washed with a 1 per
cent. solution of perchloride of mercury, it was dusted with iodoform
and packed with gauze, and covered with a cotton-wool dressing, kept in
position by means of a suitable shoe.

On January 16 there was no snatching up of the limb when the horse was made
to put weight upon it; he ate his food well, and his condition improved
every day. On January 21 the dressing was removed; the wound appeared pinky
and granular, and there was no suppuration. The clot remaining from the
haemorrhage after the operation was removed, the wound was irrigated with a
hot solution of sublimate, and then dusted with iodoform and covered with a
dressing of i
