CASES OF CANKER AND TENOTOMY. 195 
view of the sensitive parts of the foot could be obtained. From 
between the interstices of the granulation the peculiar foetid 
curd-like discharge of canker was issuing. The owner told me 
that, if I saw no chance of recovery, the animal was to be 
destroyed; but I recommended that he should be put under 
treatment. 
Having cast the horse, T removed every portion of horn from 
all parts of the foot, quite up to the hair on each side, and having 
washed it thoroughly with a solution of chloride of lime, I re- 
moved the whole of the fungous granulations with a knife, 
having hot irons ready to stop the hemorrhage, which was ex- 
cessive ; for I found these excrescences exceedingly vascular, 
so that I should think, during the operation, not less than from 
twelve to fourteen pints of blood were lost ! I found it almost 
impossible to stop the bleeding with the cautery ; for as soon as 
I arrested it in one place, it burst out in another. Having got 
the animal upon his legs, with a view to stanch the hemorrhage, 
I applied large pledgets of tow all over the foot and bound them 
up with a*long linen bandage pretty tight, and over the whole 
drew on a leather boot which I had prepared for the purpose. A 
strong dose of physic was given, and the animal remained per- 
fectly quiet until the fourth day, when I removed the boot and 
dressing. The foot presented a very extraordinary appearance, 
in consequence of the partial separation of the extensive sloughs 
caused by the cautery. The foetor being very great, I had the 
foot again well washed with the chloride of lime ; and, after 
being wiped dry, dressed all over with the submuriate of anti- 
mony, dry pledgets of tow being applied as before to the foot, 
and upon them some pieces of the old tow which had adapted 
themselves to the shape of the foot. Again, a moderately tight 
linen bandage was applied, and over all the leathern boot, as on 
the former occasion. It is needless to follow out the daily treat- 
ment of this troublesome case. In the treatment of canker, two 
things seem to me to be essentially necessary ; first, after the 
dressing, to be careful that you have an uniform and steady 
pressure ; and, secondly, that the remedies be occasionally 
changed, perhaps frequently, it being injudicious indeed to per- 
sist more than a week or ten days in one uniform remedy, even 
though improvement be taking place. 
I am quite sure that the cure is expedited by a judicious 
change of remedies. In the majority of cases the butter of 
antimony will effect wonders, and in slight cases it is a suffi- 
ciently active remedy ; but in severe cases, like the above, the 
remedies must be changed. My treatment varies. Sometimes 
I use the actual cautery ; at others, the muriate of antimony, or 
nitric acid, or solution of sulphate of copper, with an occasional
