Treatment. Take a sharp knife, and after getting a 

 twitch upon the horse's nose, and one of the fore legs held 

 up, make a straight cut over the centre of the tumor through

 fingers ; the knife here is of no use. The simply opening 

 the skin, and rolling out the fatty tumor, is called occlu-

Typhia — Typhinia — Typhus. — These are continued 

 fevers, and are lit up and fed by a specific zymotic matter in 

 the system which is generated when horses are badly fed and 

 crowded together in an inadequate supply of air. Thf 

 fevers of glanders, farcy and pyemia are good examples. 

 The seeds of the disease can only be got rid of by the 

 effectual destruction of the typhinia — its existing fe^raent 

 or leavea. (See Glanders.) 



Typhoid. — A low form of disease, accompanied with
