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 1 dr. 



Simple ointment 7 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 to 

 have the desired effect, then make a few applications of the acetate 

 of cantharides, prepared as follows : 



No. 46. Acetic acid (flu4d) 1 oz. 



Water 5 oz. 



Powdered cantharides 1 dr. 



Mix. 



Elbow Ttjmob. 



Elbow tumor (see cut on preceding page, fig. 2,) is usually re- 

 cognized as "capped elbow." It sometimes grows to an enor- 

 mous size, and not only becomes unsightly, but seriously interferes 

 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
