THE 1'1'PEU ALVEOLAR ARCH 



The dental arches correlate with function (use), with stature, witli 

 the dimensions of the face, and with those of the teeth. The western 

 as well as other Eskimo show arches that are about equal in absolute 

 dimensions to those of our taller Indians, such as the Munsee, Arkan- 

 sas, and Louisiana ; 10 but relatively to stature the Eskimo arch is 

 decidedly larger. 



The upper dental arch index ( — ^ — 1, now being used in pref- 

 erence to the unwieldy " uranic index " ( — j J of Turner, is 



rather high, showing that the arch is relatively, as well as abso- 

 lutely, broad. The same index in the Munsee averaged in the males 

 .v.'.v, in the females 82.7; in the Arkansas and Louisiana mound skulls 

 84-4- in the males anil 86.1 in the females. Data are needed here for 

 more extensive comparisons.
