because of it being so sore. In other cases, when not striking 

 so severely the inside of the knee becomes thickened and 

 hard. 



Treatment. — Allow him to remain idle. Bathe the parts 

 well with lukewarm water and salt two or three times a day 

 — the more bathing the better. Each time after bathing, rub 

 dry and apply the white liniment. If matter forms, open with 

 a sharp knife to allow the matter to discharge, then treat as 

 above mentioned. After it is healed if there is a thickening, 

 blister with the following: 



Pulverized Cantharides or Spanish Fly 2 drams. 



'Vaseline or Lard 1 ounce. 



Mix well and rub what you can nicely get on over the 

 swelling. Rub in well and grease on the third day. In a 

 couple of weeks, blister again, and repeat the blistering until 

 the thickening disappears. After this, be careful how you 

 have the animal shod, and if he is inclined to strike, wear a 

 knee boot on him. 



5. Fracture of the Bones of the Knee. 



Causes. — Falling upon the knees is often sufficient. 



Symptoms. — The animal is very lame, the knees become 

 swollen, hot and tender. 



Treatment. — Keep him quiet and bathe well with luke- 

 warm water — the more the better. After bathing, each time 

 apply white liniment. It generally takes a case of this kind 

 four or five weeks to get better. After the soreness and 

 swelling has gone it is well to blister a few times with the fly 

 blister to get the soreness and thickening out of the knee. 



6. Puffy Enlargements Around the Knees and Fetlocks (Bur- 



sal Enlargements). 



Causes. — These enlargements are the result of an injury 

 of some sort such as that which may result from striking the 

 knee against the manger while pawing, or from iying on the 

 hard floor. 



Symptoms. — There is a puffy enlargement, not sore to 

 handle, that feels as if full of oil.
