of the Head, viz. to the Eyes, the Palate of the Mouth, the 

 Nofe, but chiefly to the lower Jaw. l"he Temporal Muf- 

 cles, and Mufcles of the Face, and fome Branches which go 

 downwards, inoculating with the fixth Pair, conftitute the 

 Root or the firft Trunk of the InterccJialPair. It is owing 

 to the feveral Branches and Inoculations of the Nerves 

 following, that there is fo great a Sympathy and Conlent 

 among all thole Parts where they take their Progrels. 



lb' fixth Pair ^^^ ^^^^^^ ^^^^ inoculate with the fifth, 

 after they have pafTed fmgle through the 

 fame Hole of the Skull, and been hid fome time under the 

 2Jura Mater ; after which they fend back fome Branches, 

 which conftitute the Beginning of the Intercojial Nerves. 

 Each of thefe are divided, near the Orbit of the Eye, into 

 two, one being fpent on that Mufcle of the Eye which 

 draws it outwards ; the other on that which is only proper 

 to Brutes, called xhtfeventh Mujcle. 



The feventh Pair are the Auditory Nerves,

'^''^' under the Jnnuhir Procelles of the Cerebel- 



lurriy but in a Horfe from the Sides of the oblong Marrow. 

 Tliey have two Procelles, one of which is fomewhat foft, 

 and is carried thro' the Hole of the Os petrofum into the 

 Cells of the Ears, which it cloaths with a very fine Mem- 

 brane, and by which the Sounds are conveyed into the 

 common Senfory ; the other is laid to conduce chiefly to 

 Motion, fending forth feveral Slips to the Tongue, Lips, 

 Mouth, and Nofe, aduating the outer Organs of the 

 Voice ; others taking their Courfc to the Mufcles of the 

 Forehead, and Eyelids, and fome to the Mufcles of the Ears, 

 aflifting a Horfe in moving his Eyes and Ears, upon hearing 

 or feeing any thing that is aftonifhing to him. 

 The Ekhth ^^^ eighth Pair is generally termed the 



P^lj.^ Far vagum^ or wandring Pair, becaufe they 



inoculate and keep up a Communicatioa 

 ■with the Branches of many other Nerves, and are diftri- 

 buted, not only to the Head, but alfo into many other Parts 

 of the Body, particularly to the Heart, the Lungs, and Sto- 

 mach, as alfo to all the Vtfcera in the lower Belly.
