The Lacrymal Bones. These bones are paired. 

 They are very small and thin, found at the anterior 

 and internal part of the orbit. The outer surface of 

 this bone forms with the lacrymal notch of the superior 

 maxilla the orifice of the nasal duct. (The latter is 

 the entrance of the canal for the passage of the tears

The Maxillae Bones. They are paired, irregular in
