ANTHROPOMETRY 111 



skulls, choose the proper funnel; the rest is controlled. The results, 

 always with the condition that the proper use is made of the standard 

 skulls, are as uniform and as near the reality as can be reasonably 

 hoped for.i 



Face 



Menton-nasion height (or " nasion-menton diameter^'). — C. e., or c. g. 



The distance from menton to nasion, with the lower jaw in place and 

 the teeth in apposition. Note condition of teeth, especially as to 

 wear.^ 



Alveolar point — nasion height (or " naso-alveolar diameter"). — C. g., 

 or c. e. 



Landmarks. — See I. A. (p. 16). 

 Maximum bizygomatic diameter. — C. e., or c. g. 



Landmarks, etc. — See I. A. (p. 10). 



Base 



Basio-alveolar diameter. — C. e. or c. g. 



Distance between basion and the alveolar point. 

 Basion-subnasal point diameter. — C. e. 



Distance between basion and the left subnasal point. 

 - The triangle basion-alveolar point — subnasal point-basion gives the 

 measure of alveolar prognathism, which it is useful to show separately 

 from the facial prognathism. 

 Basion-nasion. — C. e. 



Distance between basion and nasion. The angle between the 

 basion-alveolar point line and that from the alveolar point to nasion, 

 gives the facial angle, which is the expression of the combined alveolar 

 and facial prognathism. 



Nose 

 Nasal height. — C. g. 



Landmarks: As given by I. A. (p. 16)- 



Method: Measure to base of spine, or separately to each subnasal 

 point and record the mean. 

 Nasal breadth. — C.g. 



Landmarks and Method: As given by I. A. (p. 17). 



' The apparatus is not made for the market, but it should not be difficult for any 

 one to have it constructed by foOowing the given directions. 



^ The question as to whether to allow for the wear of the teeth, when this is present, 

 or not, has not as yet been decided. Until a definite international rule is established, 

 it seems best to record both the actual measurement, and an estimate of what the 

 latter would be with teeth in normal condition.
