 Pair pafles to the inner Membrane of the Nofe. 

 (J-, at- J 1'he thii-d is feated m the inner Side of 



the Orbit of the Eye, and is continued with 

 the fungous Bones of the Noftrils. This Bone is joined to 

 four Bone^, viz. to the Forehead-bone, to the Wedge- like 

 Bone, to the laft defcribed, and the next following, and 

 is not diftinguifhed by any peculiar Name.

 and moreover contains all the upper Teeth in its leflcr Ca- 

 terns. It is much the largeft of all the Bones of the upper 

 Jaw, and is circumfcribed with divers Sutures, being joined 

 above to the Frontal-bone on the Side next the Nofe, below 

 to the Wedge-like Bone, and the Bone of the Palate of the 

 Mouth, before to the Lachrymal Bone, and one of thofc 

 Bones that make the upper Part of the Nofe, as alfo to the 

 Cheek-bone on the other Side. It has alfo three Perfora- 

 tions, two of which are under the Orbit of the Eye, for the 

 PafTage of two Branches of the Nerves that are beftowed 

 on the Face ; and the third, for the Paflage of a Vein and 

 Artery, which go the Noftrils. This Bone has likewife a 

 great Den or Cavern on each Side, in that prominent Part 

 which ftands out under the Orbit of the Eye, and on each 

 Side of the Nofe ; when there happens to be Matter pent 

 up in this Cavity, it occafions mtollerable Pain, by reafon of
