THE CRANIOMETRY OF SOUTHERN NEW ENGLAND INDIANS. 



TABLE XI. 

 Palatal Indices. 



SAGITTAL ARCS OF THE MEDIAN SKULL BONES. 



The relations between the three sagittal arcs of the frontal, parietal and occipital bones 

 to each other and to their respective chords give the proportions and amount of curvature 

 of the cranium.

 Table Showing the Amount of Variation in the Separate Arcs. 



TABLE XIII. 

 Table Showing the Amount of Variation in the Separate Chords. 



Schwalbe has shown in his paper on Pithecanthropus (Ztschr. f. Morphol. u. Anthrop., 

 Bd. I, S. 1 87) that when the frontal arc is more than the parietal arc, that is, when the 

 index, obtained by finding the value of the parietal arc in terms of the frontal as a unit, 

 is less than 100.0%, the skull more nearly approaches the condition in the anthropoids. 

 (See Table XIV.)
