where the second part begins. It articulates with the lower edge of 

 the lachrymal bone. 



The second part begins at the end of the first part as a jagged, 

 raised suture, separating the same surfaces as the first part, and runs 

 backward. It articulates with the outer border of the maxillary pro- 

 cess of the palatine. 



The length of the third part of this border varies in proportion as 

 the second part is longer or shorter. It is rounded, directed outward 

 and backward, and ends in a sharp angle with the posterior border.

It is a free border, forming the outer edge of the notch seen between 

 the palatine and the maxillary at the inner posterior edge of the bony 

 floor of the orbit. 



The orbital surface is limited externally by the sharp inner edge of 

 the malar process. The anterior boundary of this surface is the lower 

 margin of the infraorbital foramen. 



The inferior surface (Fig. 267), for a little more than half its 

 length, is merely the alveolar ridge, inasmuch as the plane surface lying 

 on its inner side, and into which it passes without a dividing line, is 

 regarded as the inferior surface of the palatine plate. At the front 

 part of the large premolar tooth, indicated in the bone in which the 

 teeth are lost by the two small transversely placed sockets, the body 

 widens out and has an internal edge of its own, which is directed 

 outward and backward and is serrated for articulation with the pala-
