TUMORS. 193 



Cause. — A specific poison in the blood, not as yet well 

 understood. 



Symptoms. — Solid, hard and irregular in shape, and 

 knotty, with no hair upon its ^surface, and presenting a

 and finally break on the [top, and present an angry and 

 malignant sore or ulcer, which cannot be healed without 

 first removing the tumor, entire with a knife, and treat

Treatment. — Removal with a sharp knife. Take a 

 sharp knife, first have a twitch upon the horse's nose, and 

 one of the fore legs held up, and cut a straight cut over 

 the centre of the tumor through the skin only. Then
