of the mouth. With the aid of a mouth speculum palpation 

 of the base of the tongue will reveal a hard, painful area in 

 the center of which the penetrating body will be found pro- 

 truding. The treatment consists of removal of the foreign 

 body and free incision across the infected area, followed by 

 mild astringent irrigations, alum, borax, sodium chloride, or 

 boric acid solutions. 



FROST BITES. 



Frozen tongues are common in horses having the habit 

 of protruding the tongue while driving (tongue lolling), and 

 not infrequently the injury thus sustained will cause necrosis 

 of the entire free extremity. Radical treatment must be de- 

 ferred until the extent of the frozen area becomes apparent 

 by the appearance of a well defined line of demarcation. 

 Amputation will hasten recovery. 



LACERATIONS OF THE CHEEKS. 



Lacerations of the cheek that mutilate or divide the 

 buccinator muscle transversely may prove a permanent detri- 

 ment to animals by destroying its necessary elasticity and 

 contractility. Constant packing of food in the cheek or re- 

 striction to the movements of the jaw (cicatricial trismus) 

 are frequent results. It is therefore evident that these 

 wounds should receive intelligent and circumspect attention. 

 Careful disinfection, ingenious closure and drainage, and 

 immobilization of the parts should not be omitted in the 

 treatment. 



TUMORS OF THE LIPS AND CHEEKS. 



Carcinomata, sarcomata, actinomycosis, warts and re- 

 tention cysts are the classes of tumors usually found on 

 these organs. The growths should be promptly removed 

 when first observed to prevent their diffusion over too great 

 an area. Pedunculated warts are removed by surgical abla-
