in the foot is destroyed; in the low operation the 
sensation is destroyed in the lower and back part of the 
foot only. 
The writer advises the low operation in all cases 
when it will give relief, and this is easily determined 
by injecting cocaine (five per cent solution) over the 
nerves at the seat of the operation. If properly per- 
formed, no bad results follow the operation and the horse 
gets relief from pain. When the low operation will not 
give relief, and the horse suffers pain, the high opera- 
tion is to be recommended. The objection to the high 
operation is, that in some eases there is likely to follow 
degeneration of the tissues of the foot to such an extent 
as to necessitate a destruction of the animal. Yet an 
animal generally gives years of service, without pain, 
when he otherwise would be useless. Neurectomy, if 
properly performed under the effects of cocaine, is prac- 
tically painless, and cannot be considered cruel. In 
fact, the cruelty lies in allowing a horse to suffer when a 
simple operation would give relief. The writer does 
not recommend neurectomy when it is to be performed 
at any point above the knee or fetlock, except in rare 
instances. The indiscriminate practice of neurectomy 
is bad; the operation is not a “cure-all,” and is to be 
employed only after careful consideration, for a specific 
purpose, and by a skilled surgeon.
