articulates posteriorly with the anterior extremity of the inferior 

 turbinate process of the ethmoid. Above the agger nasi there is 

 a groove, called the sulcus olfadorius. The superior border is short, 

 thick, and serrated for the frontal. The anterior border is sharp 

 and articulates with the nasal. The posterior border is thick, 

 and in. its lower part presents a continuation of the lachrymal 

 groove which here lodges the lachrymal sac. The lips of this 

 part of the groove are sharp, the inner articulating with the 

 lachrymal, and the outer, which is crescentic, being continuous

with the infra-orbital margin, at which point there is a projection, 

 called the lachrymal tubercle. 



The malar process is stout and triangular. Its anterior surface 

 is continuous with the facial surface of the body, and its posterior 

 with the zygomatic surface, whilst the superior surface is rough 

 and slightly serrated for the malar. 



The alveolar process forms the dependent part of the bone, 

 and is thick and curved, being convex externally and concave 

 internally. The outer plate is known as the labial plate; and the 

 inner as the lingual. The two plates are widely separated, and;
