314 THE HORSE 



in the hoof from not having the hoof pared out often enough. 

 The place is painful, causing the animal to go lame, particu- 

 larly after treading upon a stone, and when the corn is pared 

 it will be seen to have a blood-red appearance, through the 

 bursting of small blood-vessels under the horn. In some 

 cases matter will form, and unless a vent is made it will 

 under-run the sole, or appear at the coronet, and form a 

 quittor. 



The seat of the corn must be well pared out, and some 

 tow saturated with tar placed over it, and then the shoe 

 lightly tacked on, all pressure being kept off the sore heel. 



If, however, matter has formed a vent must be made so 

 that it can flow out freely ; and after fomenting the foot, and 

 syringing with Chinosol solution, a large poultice should be 

 put on. After poulticing for a day or two, as soon as matter 

 ceases to exude tar and tow may be placed over the vent, and 

 the horse may be shod and resume its work. 



Thrush. 



This disease consists of inflammation of the sensible frog, 

 which in consequence secretes pus instead of healthy horn, 

 and this issues from the cleft of the frog with an offensive 

 odour. The ragged portions of the horn should be cut away, 

 the frog washed with warm water, and a small piece of tow 

 introduced into the cleft with a piece of stick, in order to 

 wipe up the accumulated pus. A fresh piece of tow should 

 then be smeared with a mixture of — 



Tar 6 oz.

and placed in the cleft, and if necessary a bar shoe be put on 

 to retain the dressing in its place. If properly applied it will 

 neither fall out nor permit the entrance of dirt, and should be 

 renewed every two or three days. 



In an obstinate case a more powerful lotion may be used, 

 but this should not be entrusted to the care of an ordinary 

 groom.
