time, and produced considerable lameness. It was punctured by 
means of a trochar, and several ounces of fluid escaped. A 
bandage was then applied around the hock. On the following day 
the bursa had resumed its former size. The trochar was re-in- 
troduced, and the sac again evacuated. Adhesive inflammation 
now followed ; and from this time the sac became obliterated, the 
swelling diminished, and the lameness removed. Some slight 
degree of constitutional irritation supervened in this case only, 
which subsided by laxative medicine and discutient lotions. 
A chestnut gelding, aged, the property of Tegart, Esq., 
was lame from an enlarged bursa above the posterior part of the 
knee. An incision about one inch in length was made into it, 
and a bandage applied. The fluid continued to escape for a few 
days ; and, no appearance of adhesion taking place, a weak solu- 
tion of sulphate of zinc was injected, which had the desired effect. 
He worked sound for some years afterwards. 
A grey gelding, belonging to W. Hamerton, Esq., underwent 
the same operation as the grey mare on both hocks, with uniform 
success, and worked for seven years afterwards. 
A chestnut gelding, belonging to Lord Willoughby, had a wind- 
gall above the fetlock-joint. It was opened with a lancet, without 
any untoward result. 
A bay cart gelding, the property of Messrs. Rickards, was in 
the habit of working in the traces. The caps of his hocks became 
frequently bruised with the set-stick, and a large quantity of fluid 
accumulated, which was evacuated by a longitudinal incision in 
each with successful results. 
I could recite several other cases, but I hope these will be sa- 
tisfactory ; at the same time I am sure your readers will not infer 
that a degree of local inflammation of the surrounding parts did 
not take place after each operation. 
A restricted regimen was observed in all the cases both pre- 
vious and subsequent to the operations, with frequent applications 
of cold water.
