surface of the gland may be daily painted with tincture of iodine, 

 and iodide of potassium maybe given internally, in daily doses of 

 ^ to I drachm. 



Gangrene, the result of septic microbes, a weak system or too 

 severe treatment, may be met by astringent and antiseptic agents 

 locally, and by tonics, stimulants and a generous diet internally. 



In cattle the disease usually responds readily to local antisep- 

 tics, and stimulating germicidal embrocations. Camphorated 

 spirit, alone or combined with tincture of iodine ; cantharides 

 ointment with carbolic acid ; and camphor and phenol may be 

 cited as examples. 



SUBMAXILLARY ADP:nITIS. MAXILLITIS. 



Mostly in solipeds and unilateral. Causes ; traumatic : calculus ; infec- 

 tions ; ablation of papillae. Symptoms ; tardy mastication ; salivation ; 

 buccal heat and foetor ; submaxillary swelling and tenderness ; morsels 

 retained under tongue ; pa]:)illa and duct swollen, tender and firm ; abscess. 

 Treatment ; remove causes ; dislodge foreign bodies ; antiseptic lotions and 

 packing. 



This is rarel}^ seen in other animals than solipeds, is mostly 

 unilateral, and due to the introduction of microbes along with 

 vegetable spikes (barley awns, brome, wheat or oat spikes or 

 glumes) or other foreign bodies. It may also be cau.sed by cal- 

 culi obstructing the duct. The orifice of each duct, to one side 

 of the fraenum lingui, is imperfectly closed by a triangular valvu- 

 lar projection, which in some countries is erroneously cut off as a 

 diseased product (barbs), thus opening the way for the introduc- 

 tion of foreign objects. The microbes are usualh- pus germs and 

 tend to ab.scess of the gland. As in the case of the Stenonian 

 duct the presence of these germs tends to the precipitation of the 

 salivary salts and the formation of calculi. 



Symptoms. The animal may seem hungry, but masticates 

 tardily and imperfectly, and may even drop morsels partly 

 chewed. He prefers ground feed to whole, and soft mashes to 

 ground feed, while hay and other fibrous aliments may be alto- 

 gether rejected. vSalivation may be excessive, the secretion 

 drivelling from the lips, the mouth may feel hot and the sub-
