 Copper sulphate and arsenic are specific ag^ainst warts. Quit- 

 man recommends the external and internal use of Fowler's 

 solution as a spccil'ic remedy at^'ainsl warts coverinj^ a larc^e 

 surface. Retention cysts usually yield to simple evacuation 

 of their contents hy a free incision. Widely spread carcino- 

 mata and sarcomata arc incurable. 



LACERATION OF THE TONGUE. 



Etiology — Traction on the tone^ue in examining the 

 mouth or administration of medicines is the common cause 

 of laceration of the fraenum. The body of the organ sustains 

 injury from the tie chain, iron work of the stall or by being 

 bitten by animals in tlie neighboring stall. Sudden fright 

 while sleeping with the tongue between the incisor teeth is 

 the probable cause of the mysterious lacerations of the 

 tongues of horses. 



Symptoms — Ptyalism, disinclination to eat and drink, 

 champing of the jaws, rejection of food and in the later stages 

 of severe lacerations, fetor, are the chief symptoms. 



Treatment — Reposition and retention of the lacerations 

 with sutures and amputation. (Operation of amputation see 

 page 244.) 



Prognosis — The tongue is well nourished and will heal 

 well when sutured if the blood supply is not too greatly dis- 

 turbed. In the horse amputation of the free extremity causes 

 only tem])OTary inconvenience in the prehension of liquids. 

 In the ox, dog and cat loss of the free extremity is a per- 

 manent impediment in the prehension of food. 



INFLAMMATION OF THE TONGUE. 



Synonym — Glossitis. 



Etiology — Ingestion of irritants, administration of irri-
