account I then gave of the Stmilunares, or Laby-

rather CO dedroy that Bone (however feldom fuch Bones 
are to be met with) than that the Publick iliouJd be 
depiiv*d of an exacfi Defcription of that curioujOrgane, 
and thit I may give a clear Idea of all its Bony parts, I 
fhall repeat what 1 formerly advanc’d upon that Sub-

it fince. 
Before I proceed, ’tis fit I obferve that the /4uris Ex- 
terms of this big Creature lyes fiat, and not Protube- 
rent as in other C^uadrupeds, whofe Cartilaginous Sub-

from the great violence of the External Air, which up- 
on fbme occafions might perhaps injure or break the 
thin and delicate Membrane of the T^mpamm. It is 
aJfo for this reafon that the Meatus is further guarded, 
by the Contorfions and oblique Pofition of the Carti-

of a determinate quantity of Air, fufficient for the vi

did the Air admitted exceed its due proportion, no-

felf is likewife obliquely Situated, to prevent the afore- 
faid Inconveniencies. But there is no need for fuch
