SOCIETY MEETINGS.

company he had had a great number of cases of quittor. These 
cases were treated with sulphate of copper injections and poul¬ 
tices ; he had not found it necessary to treat any horse for 
seven months. They had uaually good results. 
Dr. Bryden said it was not fair to take a number of cases 
and bunch them; the history, in each case, should be con¬ 
sidered separately. Where tissue changes have gone on, it was 
impossible for them to heal in a few weeks. 
Dr. Howard asked the essayist, if he keeps the horse at work 
•or if he poultices and lays still. 
Dr. Bryden said that where the horse is not lame he poul¬ 
tices and works. 
Dr. Sherman said his treatment consists in paring away all 
the horn in the neighborhood of the sore ; he puts shoe on and 
does not touch the sinus. Whenever he has probed and in¬ 
jected he has had more trouble. He simply keeps the hoof away 
from the shoe and the case gets well. 
Dr. Bryden explained that he considered true quittor to be 
where there was a condition of hoof where the tissues are con¬ 
fined and degenerated, not so far as necrosis, but a certain 
amount of degeneration has gone on and the circulation is 
dammed back. Then when by the removal of horn and soften¬ 
ing of the foot by poultices, the obstruction to the circulation is 
removed, the tissues spring back into life again. If a bird’s 
plumage is removed it is impossible to make them grow in a 
day or two. In the same way, if a foot is confined, and the 
coronet tight, the tissues below are interfered with, a process 
•of degeneration goes on, cartilaginous changes set in, and the 
cartilage becomes hypertrophied. He thought the pathologi¬ 
cal changes in the foot ought to be thoroughly studied. 
Dr. Winchester referred to a paper read at the meeting in 
Chicago, where the fistulae was due, not to external violence, 
but to external causes ; he thought that is what takes place in 
the form of quittor referred to by Dr. Bryden. He referred to 
a case of sidebones he had treated on Dr. Bryden’s theory with 
•excellent results.
