on each side of the frenum, or "thread" (bridle), of the 

 tongue. The fluid secreted by them may sometimes be 

 seen to ooze forth when the mouth is open, especially 

 when the mind is allowed to dwell on the eating of fruits. 



THE SUBLINGUAL GLANDS 



The sublingual glands are situated beneath the tongue, 

 within the lower jaw, one on each side of the "thread" 

 of the tongue. They are small, elongated bodies, and 

 lie immediately under the mucous membrane of the floor 

 of the mouth. They have a number of ducts or openings 

 that freely discharge the fluid secretion of the glands. 

 Their function is similar to that of the parotid glands.
