LAMENESS, FROM VARIOUS CAUSES 321 
Treatment.—So soon as the injury is discovered, the part should 
be fomented often with either an infusion of hops or poppy- 
heads. It is best to apply the infusion cold, and by means of a 
sponge, the animal being kept at rest during the acute stage. 
Sometimes, in view of relieving the tension of the sprained liga- 
ment, it is customary to tack on a high-heeled shoe. This may 
or may not be necessary, and depends on the severity of the case. 
After having modified the inflammatory action, the high-heeled 
shoe may be dispensed with. Then, in order to get rid of the 
chronic enlargement, the part must be daily anointed, for a short 
time, with a portion of the following : 
No. 45. Powdered iodine...........200- edie alee, 1, OF: 
Simple ointmont..........e+.4. soeeees OU dr. 
Mix. 
After a short time, the animal may be put to light work, still 
making an occasional application of the iodine ointment. 
Should the parts about the hock degenerate into a hard callous, 
friction with cod-liver oil may be employed. Should this fail te 
nave the desired effect, then make a few applications of the acetate 
of cantharides, prepared as follows:

Ersow Tumor. 
Elbow tumor (see cut on preceding page, fig. 2,) is usually ro 
cognized as “capped elbow.” It sometimes grows to an enor- 
mous size, and not only becomes unsightly, but seriously interferea 
with the action of the elbow and its articulation. At first, the 
part is hot, inflamed, and tender. Soon effusion takes place; 
then the part is soft and fluctuating; next, albumen is deposited, 
and this, finally, is metamorphosed into fibrine, at which stage the 
tumor is large and dense ; the walls of the skin are also very much 
thickened ; in fact, when dissecting out the tumor, it appears that 
the skin is in a state of hypertrophy, or morbid growth. How- 
ever, there is usually a central orifice in the tumor which seems 
to indicate that the first trouble originated in a bursal sac, from 
external injury, either by the calking of the shoe or the toe of the
