all the half arches unite, they are lengthened' into a 

 fmall pointed body, which is eafily feen at the back part 

 of the mouth, and is called the columella or uvula. 

 On each fide, in the bottom of the fpace which is left 

 between the anterior and pofterior arches, is placed an 

 oblong glandular body, which opens into the throat 

 by eleven or, twelve excretory duels, and is called the 

 amygdala or tonfil. We have the power of flopping 

 the pafifage of air from the nofe, by drawing up the 

 foft palate, fo as to cover its pofterior openings. The 

 whole cavity of the mouth is moiftened by mucus, 

 and the liquor from the falivary glands. 



The glands which furnifh the mouth with fpittle or 

 faliva are the two parotids, which are feated immediately 

 below the ears ; the maxillary, which are feated at th % e 

 infide of the angles of the lower jaw ; the fublingual, 

 which are placed between the bone of the lower jaw 

 and the tongue; and laftly, a number of fmall glands, 

 placed in bunches about the opening of the duels, which 

 come from the parotid glands. The ftruclure of the* 

 falivary glands is like that of the pancreas* 



I (hall defer the defcription of the tongue till I come 

 to treat of the fenfe of tailing. The nofe, the ear, and 

 the eye, will be defcribed when I treat of the fenfcs to 

 which they are fubfervient. 



The cavity behind the palatum molle or foft palate 

 is called the pharynx. At the back part it is bounded 

 by the vertebras of the neck, above by the bafe of the 

 cranium, before and laterally by the foft palate and much 

 cellular -fubflance, and every way by the mufcles which 

 furround the neck. The noftrils terminate at their 

 pcflerior opening in the cavity of the pharynx, as do 

 laterally the two euflachian tubes from the internal pare 

 of the ear. 



The pharynx is a mufcular bag maped like a funnel,
