Tumors. — Tumors may be defined as circumscribed 

 swellings of different sizes, without inflammation, and 

 differing from one another, according to their situation 

 and their nature. 



(1.) Encysted Tumors. — This is a variety of tumors 

 often seen about the side of the nose of the horse, of 

 about the size of a pullet's egg, soft, and elastic to the 

 touch, with no heat, inflammation, or soreness of any 

 kind. 



Cause. — Closing of the sebaceous openings of the 

 part. Hence the elevation, swelling, and filling up of 

 that portion of the skin which contains the sebaceous or 

 suet-like matter. 



Treatment. — Open the part with a knife, and inject 

 for a few times into the inside of the tumor a teaspoon- 

 ful of the tincture of iodide, to kill the walls of the cyst. 

 The surgeon sometimes dissects those tumors out, in the 

 form of a soft ball, without opening them. This requires 

 a steady hand.

(2.) Encephaloid. — This term means a brain-like tumor, 

 so named from its structure being like that of the brain. 

 It is one of the kinds of cancers which sometimes attacks 

 the horse, but more often seen in the dog and ox.
