there Pafiages terminate. Round this is a Cartilaginous Margin, 
7V> 3 . F/g. w hich extends itfelf Inch before, and terminates in a Point-, 
10 * and behind it has, as it were, an hollownefs, wherein this Point 
fixes itfelf, and takes hold of any thing, as it were a Thumb 
pahing in betwixt two Fingers, and keeps it during Pleafure. 
This Cartilage is of great Strength, and by it the Elephant can 
take up any thing of great weight. 
'its Blood 1 come next to examine the Veflels and Nerves of th zProbofiis. 
fjejlls. . I do not find this Animal endu’d with any particular Veflels for 
this part:, but thefe here, Analagous to thofe in other Animals, 
feem to be. adapted for peculiar Ufes. In earching for the Ori- 
gin of the Probofcis, and how it proceeded from the Head, I 
feparated the Relevatores Trobofcidis ; below which obferv’d 
four confiderable Blood Veflels, a Vein and an Artery from each 
fide, lying upon and defeending in a freight Line above the a- 
fQremention'd Cartilages, and difperfing their Branches hine indc 
throughout the Subftance of the Mufcles, with two large Nerves 
accompanying them. I had not time to trace their Origin, but 
do offer thefe probable Conje&ures about them. The External 
Carotid Artery, which furnilhes Blood to the Mufcles of the Face 
and lower Jaw, has already fuffer’d fo'many Divifions and Sub- 
divifions in the vaft Mafs of large Mufcles in this Animal, that 
J tis not probable there fhould yet remain a Branch lo large and 
of fo [freight a Coprfe, as to be thus diftributed in this part •, and 
the Capillaries of the External Jugular are ufually f_> difperfed 
throughout the extream Parts whence it receives the Blood that 
'tis not to be fupposki they fhould fo foon form fo confiderable 
Branches, and thefe again unite into one Trunk at flich diftance 
from the Rafis of the Scull, where the two Jugulars are con- 
join d : And befidcs this, the Situation of the Carotid Artery 
and Jugular Vein is fo low, and thofe Branches 1 faw were fitu- 
ated fo high, that 1 can fcarce think the one proceeds from the 
other. It remains then, that I fhould enquire from whence they 
come. ’ Pis obfervable both in Human Subjects and Quadrupeds, 
that there is an Hole below the O bit of the Eye in “he Ox Max- 
HU Snoerioris, through which the Superior Branch of the fecond 
Divifion of the 5th Pair of Nerves paffes, furrouhdhg in its Pro- 
grefs a Vein and an Artery • all which are difperfed in theMuf- 
eles of the Cheeks, Lips and Nofe, and furnifli Branches for *he 
Roots of the Teeth of the Upper Jaw. This Hole is not fo con- 
fiderable in Human Subjects, but large* in Quadrupeds, elpeci-
