“ A quittor is a sign of a complication of long standing dis¬ 
ease of the foot, or of some serious lesion, such as the fracture 
of some part of the coffin bone, or an ossified cartilage, all of 
which pathological conditions we have found.” 
It is certainly very interesting to me, as Dr. Coates suggests, 
to know that this operation can be relied on. Although the cases 
given may not be altogether free from objection, yet it would be 
very unreasonable of me to doubt the merit of the operation and 
its uniform success when indorsed by those so capable of judg¬

In the December number, Dr. Bryden, of Boston, has a letter 
criticising the operation in a very friendly manner, and at the

their success in operating thus. 
Dr. Coates, in the February number, cites five cases, all of 
them acute or recent cases, in which the operation was perfectly

back six months from the time he was seen by any of the staff of 
the hospital. He was first seen by any one at the hospital, Sep¬ 
tember 9th and last seen October 22d, making forty-three days 
in all during which the animal was under our observation. It
