HRDLieKA] SKELETAL REMAINS OF EARLY MAN 241 



A portion of the upper jaw shows a nasal aperture of approximately 

 2.6 cm. in breadth; this is a very common dimension of the cavity 

 among the Indians. The alveolar process was seemingly largely 

 absorbed. 



The lower jaw is defective but shows a square chin, of good prom- 

 inence. The bone is of subaverage strength for a male. The teeth 

 are moderate in size and were apparently normal in number; they 

 show advanced degree of wear. Ventrally, there is but a slight rein- 

 forcement of the alveolar arch in the molar region, extending along 

 the second and third molars. The genial tuberosities are moderate. 

 In general the jaw shows no signs of great muscidarity. 



Measurements of the Chocorl skull and jaw: 



Vault: cm. 



Diameter antero-posterior maximum ^ 18. 6 



Diameter lateral maximum, approximately ^ 13. 9 



Cephalic index, in the neighborhood of 75.0 



Height, basion-bregma?, auditory meatus — line bregma, about 11. 2 



Circumference (above supraorbital ridges), approximately 53. 



Nasion-opisthion arc (probably shorter originally) 41.1 



Lower jaw : 



Height at symphysis, approximately 3. 3 



Height between first and second molars 3. 1 



Thickness at second left molar 1. 3 



Angle, measurement unsafe. 



The observations as well as the measurements show, on the whole, 

 features that could be duplicated without any difficulty in modern 

 Indian crania. 



Other bones of the skeleton: 



Femur. — A portion of the left bone; surface much worn and appar- 

 ently somewhat diseased, but defective character of specimen makes 

 it difficult to be certain on the latter point. Is decidedly masculine. 

 Shaft, in cross section approximates .No. 1 (prismatic) in shape. 

 The linea aspera is high and strong. Correct measurements imprac- 

 ticable on account of erosion. 



Piece of a long hone. — Difficult of identification, possibly tibia; very 

 irregular and apparently diseased surface, but no thickening of waU. 



Humerus. — A portion of the right bone. .Very stout and unques- 

 tionably masculine. The antero-posterior and lateral diameters at 

 about the middle, measure, respectively, 2.85^ and 1.85 cm. The 

 deltoid eminence is long and shows considerable development. 

 There is also a well-marked tuberosity at the insertion of the lateral 

 head of the triceps, and the ridge marking infero-posteriorly the 



' Lehmann-Nitsche gives 19.4 cm. 



2 May have been originally slightly in excess of this. Lehmann-Nitsche gives 13.8 cm. for tie breadth 

 between the parietal eminences. 



3 Lelimann-Nitsche must have measured at a different level.
