DISEASES OF THE DIGESTIVE OEGANS. 21 



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 swell- 

 ing 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 collec- 

 tion of pus. 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 creolin 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 oper- 

 ative treatment, which should be performed by a qualified veterina- 

 rian. When poulticing fails to reduce the swelling or produce 

 softening, the inflamed area may be rubbed once daily with camphor- 

 ated oil, compound iodin ointment, or painted twice daily with Lugol's 

 solution of iodin. The diet should be as recommended 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 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, 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 

 be displaced in different directions so as to produce the symptoms 

 before described. Enlarged postpharyngeal lymphatic glands are not 

 rare in tuberculosis and by pressing upon the wall of the pharynx 

 and restricting the lumen of this organ they cause difficulty in both 

 breathing and swallowing. Such enlarged glands may be differenti- 

 ated from tumors by passing the hand into the cow's throat after the 

 jaws are separated by a suitable speculum or gag.
