 and a quick and feeble pulse. The surface of the burned part 

 will become pale and leathery, or will crack, and a watery 

 discharge will flow from it. Swelling and inflammation 

 come next, and an effort of nature is made to separate the dead 

 from the living tissues by suppuration. 



The most troublesome burns in horses are about the shoul- 

 der and elbow, as, owing to the continual motion of these 

 parts, a wound upon them is very slow to heal. 



Treatmenti — The traditional treatment of burns is, to 

 smear them over, several times a day, with what is called 

 Carron oil, It is made as follows : — 



No. 265. Lime water, 



Linseed oil, equal parts. 



Mix, and apply direct to the burned surface, dredging flour over it, to 

 thicken it.
