We come next to enquire what may be the Life of the CeSule*. Ufe of the 
There have been feveral Opinions advanc’d about them ^ as 1 ft. Cellules. 
That fince the Elephant has been obferv’d to fuck up a great deal 
cf Water by the Frobofcis, that the Water perhaps is received 
into thefe Cellules , becaufe of the Communication they feem to 
have with the Probofcis, and that thereby they cool their Brain 
in hot Countries, where they abound. 2. That fince the Elephant , 
has a very acute Senlation of Smelling, they think the JNervas 
Olfaclorim is difpers’d ( after it has pafs’d the Os Ethmoides) 
throughout the fine Membranes that obduce the Laming 
which defcribe thefe Cellules. 3. That theft Cellules being in- 
terpos’d betwixt the two Tables of the Scull, they only ferve to 
keep the Head from being too weighty. As to the firft ♦, admit 
the Water could be received into thefe Cellules , which from their 
Pofition^t the Root of the Trunk, ’tis plain they cannot, there 
being no mufcular Subftance to expel theft Waters, we cannot 
fuppofe this is their Ufe. As to the fecond 3 the Tfjrvus Olfaffo - 
rixs, after it has pifs’d the Ethmoides , does not at all communi- 
cate with thefe Lamina, but penetrates the Os Vomeris , whence 
the cartilaginous Septum of the Probofcis arifes : So that thefe Cel- 
lules can be no ways aflifting for that end, the Senfation of Smel- 
ling being chiefly perform’d in the Probofcis, and not by the Fi- 
bres of the Nervtu Olfattorius difpers’d in thefe Lamina , which 
are quite otherwife difpos’d here, than in Men, Dogs, &c. whole 
Lamina Spongiofa are fituated in the Root of the Nofe fo that 
the Air muft touch them before it reach the Os Cribrofum 3 where- 
as here the Lamina are lo fituated, that the Air touches the Ner.- 
vus Olfacloritu as foon as it can touch them. The third is to me 
more probable, and Dr. Moulins is of the fame Thought, and 
that upon feveral Accounts ; fuch as the Confideration of the 
frnall extent of the Seat of the Brain, to which had the reft of the 
Head been correfpondent, it would have had no proportion to 
the Body 3 nor could the Mufcles, fit for moving the Head, have 
fufficient fpace for their Infertion, nor the Probofcis for its Origin 3 
fo that there was a a Neceftity for interpofing fome diftance be- 
twixt the inner and outer Table of the Scull. Now this diftance 
muft be fill’d up with fome intermediate Subftance, and had that 
either been carnous or olfeous, whether fpongious or folid, or 
fas fome think the Sinus Irontales, UMaxillares & Baflares in 
human Sculls are) Mucous 3 fhould either of thefe have occupy’d 
fuch vaft bounds, the Head would have been rendered too 
Q^2 weighty.
