the foot substance. There was a slight discharge from a granu¬ 
lating surface the size of a twenty-five cent piece, situated over 
the middle of the cartilage, and just above the coronary band. 
Upon introducing a probe, a fistulous track was discovered, lead¬ 
ing downward, inward and forward, to the external surface of the 
cartilage. 
History .—Had been suffering with the present condition for 
several months. Had been treated by a non-professional man 
with caustics, etc. He had also blistered the off fore coronet, so 
the owner said, “ to make the animal stand upon the lame foot.” 
The wall, bar and sole, at their point of union, had been pared 
down. 
Diagnosis .—Cartilaginous quittor. 
As the owner was desirous to have the auimal treated, the 
operation for removal of the cartilage was advised, with the 
anticipation of the removal of the lameness, but the possibility 
of a return of mechanical lameness from increase of bony growth, 
following the operation. The day following, the owner notified 
Hr. Liautard to perform the operation without further delay. 
It was decided to operate on the 18th, at 2 p. m. Accordingly 
the animal was prepared for casting, which consisted in feeding 
only sloppy bran mashes through the day, with a small feed on 
the morning of the 18th, soaking of the foot in water, and no 
dinner. At 1 o’clock gave chloral ^ U and at 2 o’clock she was 
led out of her stall very lame. 
Was blindfolded and cast upon the right side. The near fore 
leg was then removed from the hobble, and secured on top of the 
near hind leg, about midway of the metatarsal region. A stout 
cord was then secured around the leg, below the metacarpo-plia- 
langeal articulation, in order to lessen the hemorrhage which 
would necessarily accompany the operation. The hair was then 
clipped, and a probe inserted into the fistulous track inward, 
downward and forward, for about one and one-half inches, when 
it reached the cartilage. With drawing knives, a triangular sec¬ 
tion of the wall was pared down very thin, extending obliquely 
backward and downward, from the anterior portion of the carti¬ 
lage to the solar surface of the wall in front of its junction with
