PAEALYSIS OF THE TONGUE. 503 



extensively diseased, or suffering from the pressure of tumours, 

 serum, pus, or extravasated blood. It may also be induced by 

 forcible traction being applied to the tongue by the attendant 

 when giving balls or other medicines ; tliis not only produces 

 paralysis, but otherwise seriously injures the tongue. The 

 symptoms of paralysis of the tongue are — the tongue hanging 

 out of the mouth, the animal unable to draw it in, and a 

 dribbling of saliva from the mouth. 



It is good practice in all cases of disease or injury of the 

 tongue, when it protrudes from the mouth, to force it into its 

 proper position ; retaining it there by a bandage placed round it 

 and the lower jaw. Wlien the tongue hangs out of the mouth 

 for any length of time, it is dried by the evaporation of its 

 moisture, cracks, and ulcerates upon its surface, and becomes 

 exceedingly painful, swoUen, and inflamed. 



Abscesses sometimes appear at the root of the tongue and 

 istlmaus faucis, interfering with deglutition, and giving rise to 

 cough. The mouth is to be examined, and the abscesses opened 

 by puncture or by laceration with the finger.
