WARTS 



These are quite commonly seen on the skin of hogs. Warts 

 are caused by piUng up of thickened skin, and they are often seen 

 in run-down, stunted animals. Old boars also frequently develop 

 warts. The favorite locations for warts are the inner surface of the 

 ear, the inside of the thighs, and the muzzle. An excellent speci- 

 men of warts, taken from the inner surface of the ear by Dr. Waugh, 

 of Pittsburgh, Pa., is to be seen in the Pathological Museum of 

 the Terre Haute, Ind., Veterinary College. 



These growths often reach considerable size, and it is not un- 

 usual to find a wart the size of a hen's egg on the throat or ear of 

 an affected animal. 



Treatment for warts consists principally^ in their surgical re- 

 moval by means of the knife or scissors. Following the removal 

 of the growth the surface may be touched with a red-hot iron to 

 destroy the base of the wart. Where the wart is small in size it 

 may be successfuly treated by applying daily a salve containing 

 1 dram of salicylic acid in 1 ounce of vaselin or lard. 



Warts are harmless growths, and it is just as well to leave them 

 alone unless they become so large as to be troublesome.
