ally fuch as feed upon Grafs or Hay ; infomuch, that by she big- 
nefs of this Branch of the 5th Pair in an Oxe or Hart, we may 
reafonably conjecture they have a partial Tafte, and a moft acute 
Smell by the Upper Lip, the better to enable them to chufe their 
food : For at the Difledion of a Calfs Head, you’ll perceive - 
both this Nerve and the Blood Veffels much bigger than what 
might be thought requifite for furnilhing either Blood or Spirits 
to this part, were there not fome extraordinary ufe for both* 
Now in this our Subject there is an Hole in the Os Maxilla fype- 
rioris (u) Fig. 1. (ra) Fig. 2. (8.8.) Fig. 3. fo remarkable for its Tab 
bignefs, fo commodioufly fituated, and fo well guarded, that 1 
have good Reafon to believe it may be defigned for Tranfmif- 
fion of the afoie-mentioned Artery, Vein, and Nerve, and 
that all thefe are di' ibuted into the Trunk : For if we con lid er 
the largenefs of this Hole for this Branch of the 5th Pair, as it 
is to be fee : in the inner Surface of the Bajis of the Scull, whole 
Capacity is fuch as to contain a Nerve of above twice the bignefs 
of what we uippofe it to have been ; if we again confider the 
Crena (x x) which palfe: etwixt the Hole for the fecond Branch 
of this $th Pair and the 3d (i i } ) and how the Hole for the Artc~ 
ria dura aJWatris (k k) is only feparated from the Hole for the 
third Eranch (i i) by a fmall Boney Septum we may fuppole that 
this Arteria dura Matris enters where the third Branch of the 
5th Pair goes out, and fends up one Branch (kk) which imme- 
diately enters the dura Mater, and another which runs forward 
in this Crena to the Hole for the fecond Branch of the 5th Pair 
(hh.) and goes along with it, and palfes out below the ; I .ami-net, 
which frames the upper part of the Sinus for the Orbit of the Eye 
(S) (2) and runs forward along witU the fecond Branch to this 
large Oval Hole-, whereafter it is come, it afeends obliquely in • 
a Crena to be Hill feen in the Bone, till it comes to the Root of 
the rrobofeis , where it is difperfed as above-, and the Vein re- 
tur»ing by the fame Hole runs along with the other two, tho’ it 
does not enter the Scull ; but running backward, palfes in below 
the forefaid Lamina, and defeends where the Arteria dura Ma- 
tris afeends. 1 cannon pofitively determine the Capacity of thefe 
Blood Veffels at the Root of the Probojcis $ but they were very 
confpicuous, and could admit of a Goofe Quill, tho’ they were 
empty •, and when they were full, i doubt not but they were a- 
' bove twice as big-
