DISEASES OF THE DIGESTIVE ORGANS. 19 



when submitted to proper treatment, disappears in a comparatively 

 short time. In other cases, however, they remain enhirged, even 

 after the animal recovers its appetite. In tuberculosis, lymphatic 

 glands beneath the parotid glands are sometimes enlarged, thus 

 causing the appearance of enlarged parotid glands. 



Treatment. — A warm bran poltice, made by mixing bran with a 

 hot 2 per cent compound cresol solution in water, should be applied 

 on the swollen gland and kept in place by means of a bandage. 

 Wlienever the poultice has cooled it should be replaced by a new 

 one. This treatment should be continued until the pain is less and 

 the swelling is reduced or until there is evidence of pus formation, 

 which may be ascertained by examining the surface of the gland with 

 the fingers ; and when, on pressing any part of the surface, it is found 

 to fluctuate or " give," then we may conclude that there is a collection 

 of pus at that place. It is well not to open the abscess until the 

 fluctuation is well marked, as at this stage the pus or matter is near 

 the surface and there is less trouble in healing the wound than if the 

 pus is deep seated. The abscess should be opened with a clean, sharp 

 knife. The poulticing should then be continued for two or three 

 days, but the form of the poultice should be changed, by replacing 

 the bran with absorbent cotton and pouring the compound cresol 

 solution on the cotton. At all times the wound should be kept clean 

 and the cavity injected once or twice daily with a solution of 1 dram 

 of carbolic acid in 8 ounces of water. Under this treatment the pus 

 may cease and the wound heal without complications. Saliva may 

 issue from the orifice and result in the formation of a salivary fistula. 

 This requires operative treatment by a qualified veterinarian. When 

 poulticing fails to reduce the swelling or produce softening, the in- 

 flamed area may be rubbed once daily with camphorated oil, com- 

 pound iodin ointment, or painted twice daily with Lugol's solution 

 of iodin. The diet should be as recommended under Pharyngitis 

 (p. 17). 



PHARYNGEAL POLYPI. 



Tumors form not infrequently in the pharynx, and may give rise 

 to a train of symptoms varying according to their size and location. 

 The tumor may be so situated that by shifting its position a little it 

 may partially obstruct the posterior nares (nostrils), when, of course, 

 it will render nasal breathing very noisy and labored. In another 

 situation its partial displacement may impede the entrance of air 

 into the larynx. In almost any part of the pharynx, but especially 

 near the entrance of the gullet, tumors interfere with the act of 

 swallowing. As they are frequently attached to the wall of the 

 pharynx by a pedicel or stalk, it will be seen that they may readily 

 be displaced in different directions so as to produce the symptoms
