REPORTS OF CASES.

was not very favorable, but made a statement that the animal 
was no good the way she was and worthless as far as work was 
concerned, but if they would consent to an operation we would 
fathom and trace the nail-hole as far as it went and in so doing 
the chances would be in favor rather than against her, even if 
she did not make a complete recovery, and a more correct 
diagnosis could be made. After some hard talking they decided 
in favor of an operation. On the following day the mare 
was led out on a bed of straw, hobbled and cast. After the 
choloroform was administered by the doctor and everything 
ready the limb was released from the hobble, the foot cut down 
into proper shape (as it had grown very much since her mishap), 
a solution of bichlor. hydrarg., i to 1000, was used in washing 
the foot thoroughly before the operation ; a ligature was then 
applied below the fetlock. Then taking the foot we cut down, 
removing part of the horny frog and sole, making the opening 
somewhat circular in form. This being done the direction of the 
nail-hole could be seen distinctly passing obliquely downwards 
and somewhat outwards. This was followed by removing the 
same area of sensitive frog and sole, thus bringing into view the 
coffin bone and flexor perforans tendon, to the extent of the open¬ 
ing ; the sole of the coffin bone was as black as tar. How far 
this extended it is impossible for me to say, but this was removed 
by curetting. The parts were kept washed thoroughly during the 
entire operation with a solution of bichlor. hydrarg. The dress¬ 
ing consisted of Sal.-Lister and absorbent cotton, with plenty of 
pressure on the sole from the bandages that were applied. The 
ligature was removed from below the fetlock, after which we 
had some haemorrhage, which looked a little discouraging, but it 
soon subsided. The hobbles were removed and the animal 
allowed to rest in the recumbent position, after which she rose 
none the worse for the operation. Not having seen the mare 
afterwards, although I kept track of her through the doctor and 
owners, a fungus growth appeared two weeks after the 
operation, which was removed by argenti nit. In four weeks 
after this she was removed to pasture and allowed to run up to 
the last of September, after which she was brought to the city 
with as perfect a foot and as sound as before her misfortune.
