14. Breadth of the nasal cavity; e.g. 



Landmarks: The lateral borders of the nasal aperture. Find with 

 the compass the greatest diameter of the aperture in horizontal line. 



15. Inter-orbital breadth; e.g. 



Landmarks: Bilaterally — the point where the posterior lacrymal 

 crest meets the inferior border of the frontal. 



16. Orbital breadth. 



Landmarks: Mesially — the dacryon, or point of meeting of the su- 

 tures formed by the frontal, the lacrymal, and the ascending part of 

 the superior maxillary bones; 



(If the dacryon is obliterated, or in an abnormal situation, take the 

 point where the posterior lacrymal crest meets the inferior hffoder of 

 the frontal) ; 



Distally — the external border of the orbit, at the point where the 

 transverse axis of the orbit meets the border, and parallel as far as 

 possible to the superior and inferior borders. 



17. Orbital height; e.g. 



Landmarks: The superior and inferior borders of the orbit, avoid- 

 ing the superior and inferior notches, when they exist. Take the max- 

 imum distance between the two borders along an axis perpendicular 

 to the preceding measurement [orbital breadth].

18. (a) Breadth of the upper alveolar border; e.g. 



Landmarks: The external surface of the alveolar border, on each 

 side.
