swallowed with difficulty. In many cases the swelling of those 

 glands, when submitted to proper treatment, disappears in a com- 

 paratively short time. In other cases, however, the gland remains 

 enlarged, 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 poultice, made by mixing bran with a 

 hot 2 per cent solution of creolin in water, should be applied on the 

 swollen gland, maintained in place by means of a bandage. When- 

 ever 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 at that place 

 a collection of pus. It is well not to open the abscess until tho 

 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, shaqi 

 knife. The poulticing sliould 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 creolin solution on 

 the cotton. At all times the wound should bo kept clean and the 

 cavity injected once or twice daily with a solution of 1 dram of car- 

 bolic 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 fonnation of a salivary fistula. 

 This requires operative treatment, which should be performed by a 

 qualified veterinarian. When poulticing fails to reduce the swelling 

 or produce softening, the inflamed area may be rubbed once daily 

 with camphorated oil. compound iodin ointment, or painted twice 

 daily with Lugol's solution of iodin. The diet should be as recom- 

 mended under Pharyngitis (p. 20). 



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 nasiil 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, they will interfere with the act of swal- 

 lowing. As these tumors are frequently attached to the wall of the 

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