ftance, as alfo fome proper Mtifcles cover'd on their out- 

 iide with Skin and Hair, but on the infide with a Mem- 

 brane common to the Mouth and Stomach. 



The Ufes of the Lips are to gather in Hay or Oats, or 

 otlier Food, and to retain it while it is chewing ; they like- 

 wife ferve to keep the Gums and Teeth from external In- 

 juries. 



The Parts of the Mouth are fome of them The Internal 

 flefliy and fome of them bony : The fiefliy ^^^*^ °f ^'^^ 

 Parts are the Lips laft defcrib'd ; as alfo ^l^^'th. 

 the Mufcles of the Cheeks and lower Jaw. The bony are 

 the upper and lower Jaw, together with the Teeth. 



All thefe Parts, excepiing the Teeth, are cover'd or 

 lin'd with a pretty thick Membrane, which in the Palate 

 is fugged and knotty, by reafon there are a great numbsr 

 of Glands lie under it, out of which Part of the Slaver is 

 feparated into the Mouth. 



The Parts contain'd within the Mouth, are the Teeth, 

 the Oi Hy aides ^ or Bone of the Tongue ; befides which, 

 there are the Gums, the Palate, the Uvulae the Kernels call'd 

 the Almondi of the EarSy the Tongue and its A'lufcles. 



The Gums are compofed of a flefhy q-j n . 

 Subftance deftitute of Motion, that fo the 

 Teeth might the better be fa-ften'd in their Sockets. 



The Palate^ fo calFd from its being q-j p t 

 fenc'd or pal'd in with Teeth, forms the ^ ^a e. 

 upper Part of the Mouth. It extends from the back 

 Part of the Mouth to the fore-Teeth, but is not fo

 of eighteen Bars, and confifts of Bones and peculiar glan- 

 dulous Flefh, which are cover'd with a thick Coat, which 

 is full of Perforations or little Holes, that aftbrd a Pallage 

 to the Slaver, w^hich is feparated from the Glands above- 

 mention'd. 



The Uvula is a red fungous Kernel^ 7hs Uvala, 

 ibmewhat longifh, feated at the b?>ck-part 

 ©f the PalatCj where the internal Pailage of the Nofe opens 

 into the Mouth, hanging downward, v.'irh a fmall bui 

 bluntifh End over the Chink of the Larynx. 



The Ufe of the UvuJa^ is to moderate the Coldnefs of 

 the Air before it paflcs into the Lungs, and to hinder any 

 lliinji from falling into the Windpipe : In a Horfe it is of
