CHAPTER XXIII. 
DISEASES OF THE FRONT AND HIND LEGS. 
1. Capped Elbow or Shoe Boil. 
This is a thickening at the back of the elbow joint. 
Causes. — Shoeing and leaving a long heel on the shoe 
which catches the animal in that part while he is lying down, 
or from wearing a heavy belly band on the harness, which 
rubs against and irritates the 
elbow may be the cause. 
Treatment. — If caused 
by the shoe, have him shod 
with a short-heeled shoe, 
and, for a time, tie an old 
bag around the foot, so that 
when he is lying down the 
foot does not irritate the 
elbow. Treat as follows as 
soon as noticed : Bathe well 
with lukewarm water and 
vinegar twice a day. If not 
raw but merely swollen, use 
the white liniment after 
bathing. If raw, use the 
white lotion. This generally 
effects a cure. In some cases 
it festers and matter forms. 
It is then necessary to open 
it with a knife at the lowest pig. 6o.-Capped Elbow, 
part of the swelling and 
treat as above mentioned, only melt a little green salve and 
put it in the hole each time after dressing until it heals. If it 
is of long standing, and there is a large, hard lump formed on 
the cap of the elbow, the only treatment is to throw the 
animal, secure him, and skin the lump out carefully. This 
can be done without causing but little bleeding. After the 
lump is cut out, draw the skin together with a few stitches
