tion or ligation and the diffused ones by the use of caustics. 

 Copper sulphate and arsenic are specific against warts. Quit- 

 man recommends the external and internal use of Fowler's 

 solution as a specific remedy against warts covering a large 

 surface. Retention cysts usually yield to simple evacuation 

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

 mata and sarcomata are incurable. 



LACERATION OF THE TONGUE. 



Etiology — Traction on the tongue 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 the 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 temporary 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- 

 tating medicaments, bit bruises, wounds from dental irregu-
