248 DISEASES OF THE UPS AM) CHEEKS. 



selecting and preparing the food, and in the management of the 

 animal. Complications are treated on general surgical principles. 

 In suppurative forms of skin inflammation, diseased parts should be 

 promptly removed with the knife. 



Chronic inflammation of the lips and cheeks in oxen is sometimes 

 due to actinomycosis. Klepzow, who examined 2,000 slaughtered 

 cattle, found actinomycosis of the lips in 5*6 per cent. Several hard, 

 painless swellings appear in a line with the molars. The skin covering 

 them is at first mobile, but later becomes adherent and finally breaks, 

 a muco-purulent fluid being discharged from the wound, which is 

 surrounded by flabby granulations which readily bleed. 



The cause is infection with the actinomyces from the cavity of the 

 mouth. 



Treatment consists in early opening of the swellings, drastic 

 curetting of the parts and dressing or plugging with tow saturated 

 in tinct. iodi. Potassium iodide should be administered. 



Like actinomycosis in cattle, botryomycosis of the lips and 

 cheeks in horses is not uncommon. Small fibrous swellings form, 

 most frequently at the points where skin and mucous membrane are 

 coterminous. 



Treatment should be undertaken early ; it consists in removal 

 of the swellings, careful disinfection and suturing of the wound. 

 For this affection potassium iodide may be administered, but its 

 effect is uncertain. 



(3.) TUMOURS OF THE LIPS AND CHEEKS. 



Warts. In dogs and horses the lips are not infrequently the seat 

 of great numbers of small warts. These new growths occur both 

 on the mucous membrane and on the skin, and vary from the size 

 of a pin's head to that of a pea. Their covering is often wanting 

 in pigment, in consequence of which they appear red on the surface 

 and are often thought by laymen to be parasites. They are almost 

 always found in young animals, and though often unsightly, some- 

 times bleeding, they appear to cause no particular inconvenience, 

 and may disappear after a short time without apparent cause. 

 Papillomata may be transmitted from one dog to another ; though 

 attempts to inoculate other animals have proved ineffective (Garcia). 

 If mastication be interfered with, they can be removed with scissors ; 

 but if they cause no inconvenience it is better to await their 

 spontaneous disappearance.
