Diso7'ders of the Mouth. 125 



they should be touched with the stick of nitrate of silver, or 

 swabbed with a strong solution every day until they disap- 

 pear. 



2. Vives. 



These are chronic enlargements of the glands of the lower 

 jaw, encroaching on the cavity of the mouth. They are lia- 

 ble to become tender and to discharge in the mouth. 



The treatment is by applying to the skin over where the 

 swelling can be felt an ointment of biniodide of mercury, 

 one drachm of the biniodide to the ounce of lard, repeated 

 daily until a free secretion from the skin is established. 

 This will nearly always disperse them. Or they may be 

 painted with tincture of iodine ; or a tartar emetic ointment 

 may be used, as : — 



No. 83. Tartar emetic, 2 drachms. 



Olive oil, 1 drachm. 



Lard, 1 oz. 



Eub together the tartar emetic and oil until smooth, then add the 

 lard. For a pustulating ointment. 



3. Barbs and Paps, 



By these and other names are known the swellings caused 

 by obstructions of the ducts of the salivary glands. Their 

 position indicates their origin. 



The treatment is by an incision over the swelling with a 

 sharp pointed knife ; or by holding a pencil of nitrate of sil- 

 ver against it every day for a moment or two. The horse 

 should have a moderate dose of a laxative medicine (3 or 4 

 drachms of aloes), and his food be changed for a time. 



4. Tender and Bleeding Gums. 



In young and scrofulous, and in quite old horses, it is not 

 unusual to find the gums swollen, and to the touch soft, 

 spongy and bleeding easily. Such horses have usually wide 

 spaces between the teeth, which are found to be full of partly 

 decomposed food.
