weighty. Therefore it is wifely order'd by Providence, that 
there (hall be only thin Lamina of Bones, fo dilpers’d, that the 
outer Table of the Scull may be more ftrengthened for ftpporting 
the Weight of the Mufcleof the Head, Lower Jaw, and Prcbofcus- 
adhering thereto, that it may have a Communication with the 
inner Tablfi, and that the fpace betwixt thefe Lamina may be 
empry } left by any intermediate Subftance, the Head had been 
too heavy, as is faid, and the inner J able fo hnrthen’d as to 
prefs too muck upon the Brain, which might have difturbed the 
zslconomia Animals*. Analogous to this Struifture we find in Oxen, 
which have the fame Cellules betwixt the two Tables of their 
Scull, efpecially toward the Horns, whofe Flints, as they are 
call'd with us, or the boney Subftance, whereby that part of the 
Horn, which is t ward the Head, is fill’d, is likewise cellulous, 
left by their Weight, together with that of the . Horns, they 
fhould prove uneafy to the Head : But left by reafon of thefe 
Vacuities, which are all plac'd in the upper and fore-part of the 
Head of the Elephant , (Tor the Brain and Elevatores Capitis are 
fflfncient to deprefs its back-parts) it fhould be rendred fo light, 
that it could not be equally pois’d or kept fteady, the Teeth, 
both in the Upper and Lower Jaw, are rendred thu^ weighty to 
counterbalance it. 
We ccmc next to confider the inner Surface of the Scull, where 
the Brain is lodg’d : ’tis in Figure like an Human one, but more 
Spherical, being from the Right to the Left 10 Inches, from be- 
fore to behind 9 Inches, and from above to below at the anterior 
Foffa 7 Inches, betwixt the middle 5 Inches, and at the pojhrior , 
or Seat cf the Cerebellum , 4 \ Inches. Lc has 4 F(fpe y and 5 E- 
sninences. The anterior Evffa (b. b) is circnmfcrib’d by the fore- 
part of the inner Table of the Scull before, and by the two ante- 
rior Eminences (c.c.) behind. Here the Brain fends forth its 
grcatefl Produdion-*, for at the hind part this anterior F<Jfa is 
deprefs’d ftreight down near z Inches, where the Os Ethmoides 
begins, which is of a fingular Figure and Struriure ; for from the 
fore-part of the Seat of the Brain in the middle, there is here,, 
as in moft Sculls, an Eminence which runs obliquely down- 
ward, till it begins to form the Crifi* Galls (d.) fo call’d in Hu- 
man Subjects. This Crifta Galls divides the Os Ethmoides into, 
its right and left Part •, ’tis pretty thick and broad at the Bafe, 
whence it arifes from each fide, till it begins to form a Crena 
is perforated by 3. Pair of Holes 3 and then there arifes,
