The Head ( A.) being compos’d of the Bones of the Upper 
and Lower Jaw, on its upper Fart is almolf iound, having two 
Eminences with a Depredion in the middle before } which De- 
predion, as it runs back, becomes a deep Sinus \ and thde Emi- 
ncncies drawing nearer to one another, and as they afeend be- 
hind, inclining obliquely forward, are not unfitly compar’d by 
Mr ‘\nj to a Man's Buttocks : About its middle part it is almoit 
Quadrangular, being fiat before, till it comes to the Root of the 
Trunk (a ) where it is deprelt, for the more convenient Lodging of 
the Probofcis , till it has paft over the Mouth (£.) At each fide 
’tis much contracted for the moving of the Mufcles of the Lower 
Jaw (c.) at its back Fart it becomes very narrow, with feveral 
Eminencies, Sinus's and Holes; of all which in order. At its 
lower and fore part, the Bone of the Palate is narrow, where the 
Prcbofc is hangs over : On each fide of which are the Alveoli for 
the Tusks ; and behind, the Lower makes up all the reft of the 
Head, as to its External view. 
We fiiali begin the particular Defcription of the External Parts 
of the Head at its fore-part^ the Diameter of whofe upper p^rc 
is i l oot, the two Eminencies are alraoft round (a. d.) and the 
Stmts in the middle is 10 Inches from the higrt to the Left and 
2 Inches deep ( e. ) from thence defending 5 Inches, the Bone is 
flat before, and begins to form an Angle on each fide for the Ca- 
vity, which contains the Mufcles of the Lower Jaw and Probofcis 
between which Angles ’tis 11 Inches iff.) thence defending 
gradually the Angles tend outward, till they come to the upper 
Production for the Orbit of the Eyefg.g.) where they are 17 
Inches ; betwixt which is fituated the Hole for the Root of the 
Trunk (a.) 1 his Hole runs acrofs the Head, being from the 
Right to the Left 12 Inches, and f cm below to above on each fide 
7 Indies for in the middle it has a Protuberance where the Carti- 
laginous Septum arofe, which defeends 2 Inches, and terminates in 
an obtufe Poin\ Within this Hole are to be feen feveral of the 
Lamina, whereof the Cellules which run betwixt the two Tables 
of the Scull are compos’d (h. h. ) of which hereafter, with the 
Vomer in the middle (L) whence the Septum of the Trunk arifes 
'tis pretty thick here, and is compos’d of two Lamina, with a 
fpongy Rone in the middle. At is upper and fore part* it com. 
mum cates with the Os cribofum ■, and you may fee the feveral Per- 
forations, through which a great many Branches of the Ner-ous 
Olf ?Ll o't ins pafs, and cover the Surface of the Cartilaginous Sep. 
turn.
