REPORT OF NATIONAL MUSEUM, 1887. 



or more extended observations may prove that this flattening of the 

 skull only occurs in a certain proportion of the representatives of this 

 race, and not in every individual.

Dr. R. W. Shufeldt, U. S. Army, sent to Prof. Sir William Turner, of 

 Edinburgh, a Navajo skull, which is described in the Journal of Anat- 

 omy and Physiology, vol. xx, p. 430, as follows : The skull presented a 

 well-marked parietooccipital flattening, obviously due to artificial press- 

 ure, which had been applied so as to cause the suprasquamous part of 

 the occipital bone and the posterior three-fourths of the parietal to slope 

 upwards and forwards. The frontal region did not exhibit any flatten- 

 ing, so that in this individual, and it may be in his tribe of Indians, the 

 pressure applied in infancy was apparently limited to the back of the 

 bead. Owing to this artificial distortion the longitudinal diameter of 

 the head was diminished, and the cephalic index 94.6, computed from 

 Br. Shufeldt's measurements of the length and breadth, was therefore 

 higher than it would have been in an uudeformed skull. The cranium 

 Was by nerbrachy cephalic.
