lowest point at the innermost part, by a horizontal incision. The fluid may 
then be squeezed out. The most scientific and at the same time the best 
method, is to draw off the fluid by the aspirator. After the application of a 
blister, pressure by means of a bandage should be maintained. This is also 
necessary after the evacuation of the sac by puncturing. In the latter case 
the bandage should be kept firmly applied, so as to maintain the walls of the 
sac in close contact, and to cause their union together. 
Capped elbow, like the rarer variety of capped hock, is due to the 
appearance of a serous sac at the back of the elbow joint. It is generally 
caused by a bruise, the result of lying down with the heel in close contact 
with the elbow. Warm water fomentation, assiduously carried out, is the 
best treatment. After each fomentation, the elbow may be rubbed with the 
ordinary white linament. The fomentations should be carried on for an 
hour at a time, four or five times daily, fora few days. If these measures 
are not Successful in causing the disappearance of the tumour, it may be 
smartly blistered, or a seton may be passed through it. In some instances, 
when the tumour becomes indurated, it may be removed by an incision in 
the vertical direction through the skin.
