76 ELEMENTARY ANATOMY. [LESS. 



ales, or wings, and between the two pairs are a pair of large 

 openings separated by a median partition and directed back- 

 wards. These openings are the hinder nostrils, or posterior 

 nares. At each side of the skull, behind the orbit, is to be 

 seen an arch of bone a sort of flying buttress connecting 

 the skull and face together, arid termed the zygoma. 1

a, the greater wing of the sphenoid, which also appears in the orbit on the outer 

 side of the opening marked (2) ; f, frontal ; m, malar ; )tia, mastoid process ; 

 me, median part of the ethmoid dividing the nasal fossa vertically in the 

 middle line ; , nasals ; o, lesser wing of sphenoid bounding the opening 

 marked (2) on the inner side ; f, parietal ; s, squamous part of temporal 

 bone; i, optic foramen ; 2, sphenoidal fissure ; 3, infra-orbital foramen. 



When the skull is looked at in front, we see beneath the 

 forehead two conical sockets for the eyes, termed the orbits^ 

 and between them the bony prominence of the nose, beneath 

 which is a large aperture medianly divided by a vertical 

 partition and forming the front nostrils, or anterior nares. 



Beneath the outer and lower angle of each orbit the bony 

 projection of the cheek is noticeable, termed the malar 2 pro- 

 minence ; and the skull is bounded below (the mandible being 

 removed) by the free border which gives attachment to the 

 teeth, and is termed alveolar, because the teeth are lodged in
