The anthropometry of Site No. 20 certainly suggests that here we 

 are dealing with an intrusive group when the osteological measure- 

 ments are compared with those from the other sites in the region. 

 The bones are shorter, heavier, showing more indication of muscula- 

 ture, and the individuals were probably shorter in stature. Most 

 significant, however, is the great contrast in craniology. The skulls 

 from all of the other sites are distinctly brachycephalic with many 

 evidences of artificial deformation; three of the skulls from Site No. 

 20 are definitely dolichocephalic, the average cephalic index is 79.99, 

 while the mean cephalic index is 76, which throws the entire group 

 barely into the mesocephalic division. When in addition to this 

 osteological evidence we take into consideration the type of burial, 

 we would suspect that the skeletons of Site No. 20 represent a group 

 of invaders, possibly killed in battle, and their bodies thrown un- 

 ceremoniously into a pit. This is of course a mere conjecture, but 

 the fact remains that the material from Site No. 20 does not conform 

 in osteometry, in location, nor in the method of burial with that of 

 the other sites in the area. 



Site No. 22 



Only one skeleton from Site No. 22 was in good enough condition 

 to be studied and measured. This skeleton is reported as follows: 



Skeleton No. 17. — Adult male. Skull : Maximum length, 171 mm ; 

 maximum breadth, 157 mm ; cephalic index, 91 ; glabella-inion length, 

 160 mm; height, 140 mm; nasal length, 50 mm; length of orbit, 35 

 mm ; breadth of orbit, 37 mm ; length of occipital foramen, 32 mm ; 

 breadth of occipital foramen, 30 mm; sagittal-cranial arc, 341 mm; 

 circumference, 520 mm; bigonial breadth, 110 mm; bicondylar 

 breadth, 131 mm; length of ramus, 58 mm; breadth of ramus, 34 mm. 

 The teeth are well worn. Long bones : Right humerus, 317 mm ; left 

 humerus, 318 mm; left radius, 244 mm; right femur, 453 mm; left 

 femur, 454 mm ; left tibia, 378 mm. 



In attempting to make a summary of the data furnished by the 

 skeletal material from the Norris Basin we have had two prime 

 objects in view: (1) To attempt to construct an anthropometric pic- 

 ture of the group of aborigines which inhabited this region, and 

 (2) to compare this group with other groups found elsewhere in the 

 Mississippi Valley. 



To accomplish these two objects it is necessary to make a brief 

 tabulation of the more important of the measurements which enter 

 into consideration. In making this tabulation we have omitted the 

 data from Site No. 20, since, as we have stated, this seems to repre- 

 sent intrusive material. Also, we have followed the usual anthro-
