Lameness, 201 



CORNS, 



Definition. — Small swellings or tumors on the sensitive 

 Bole, in the triangular space between the bars and the wall at 

 the heel, found in the fore feet only, and almost always in 

 the inside heel. 



o^ 



Causes. — The cause of corns is almost alw^ays bad shoeing 

 or wearing the shoe too long a time. 



Symptoms. — Corns do not always cause lameness, though 

 as a rule they do. They are alw^ays sensitive to pressure, 

 and usually appear as tumors of a hard, horny character. 



Treatment. — The shoe should be removed, and if there is 



inflammation, the foot should be poulticed, and if the corns 



are festered, an opening made to give vent to the pus. The 



seat of the corn should be pared, care being taken not to cut 



out portions of the bars or the frog. Many "corn salves'^ 



are recommended. Mr. Chawner gives the following: — ■ 



No. 212. Tar, 



Beeswax, 



Honey, of each, \ Vo. 



Glycerine, 3 oz. 



Lard, I lb. 



Nitric acid, 2 drachms. 



Melt the lard and beeswax together, stir in the lard and other ingredi- 

 ents, and stir till cold. 



Another corn plaster is — 



No. 213. Subacetate of copper (verdigris), f to 1 oz. 

 Oil of turpentine^ 2 oz. 



Yellow wax, J lb. 



Melt together and apply on a piece of leather. 



THRUSH, OE FEUSH OF THE FROG. 



Definition. — A diseased condition of the secretions from 

 the frog, commencing at the cleft and extending over the 

 ^vhole of it, characterized by the discharge of a foul and fetid 

 material.
