be found in faulty food or drink, diseased teeth or gums, disor- 

 dered stomach, or the irritant food, medicine or poison ingested. 

 If more is wanted simple astringent washes like those recom- 

 mended for stomatitis and a free access to pure water will often 

 suffice. Tartar emetic or opium has been known to succeed in 

 obstinate cases. Friction over the parotid or submaxillary gland 

 with camphorated spirit, tincture of iodine or soap liniment is 

 sometimes required. In mercurial salivation chlorate of potash 

 is especially to be commended, and when the bowels have been 

 unloaded of the agent, iodide of potassium will hasten its elimi- 

 nation from the tissues and blood. 



DILATED SALIVARY DUCTS. SALIVARY CALCULUS. 

 SALIVARY FISTULA. 



These are all surgical diseases and are to a large extent inter- 

 dependent. The impaction of the calculus in the duct leads to 

 over-distension of the duct posterior to the obstruction, and the 

 rupture or incision of the distended duct, determines the fistula. 

 It is only necessary here to point out the seat of these lesions : 

 the distended sublingual ducts constituting a more or less rounded 

 swelling to one side of the frsenum lingui, the Whartonian duct 

 forming a tense rounded cord from the papilla back of the lower 

 incisor teeth backward on the inner side of the lower jaw, and 

 the Stenonian duct forming a similar tense cord from near the 

 middle of the cheek down around the lower border of the jaw in 

 company with the submaxillary artery and backward on the inner 

 side of its curved border to the parotid gland. 



For the more precise lesions, symptoms and treatment of these, 

 see a work on surgery.
