head, as in the instance of the Chenouks and other tribes of the 

 Columbia river, the skull expands laterally in proportion as it is 

 depressed above ; whereas, in these people, the head is narrow 

 from the face to the occiput. It seems probable that this con- 

 formation was produced by placing splints or compresses on each 

 side of the head- from the cheek bones to the parietal protube- 

 rances, and another on the forehead, and confining them by rotary 

 bandages. In this way the face, in the process of growth, would 

 be protruded in front, and the head elongated backwards; while the 

 skull, in all other directions, could expand comparatively little. 

 These remarks will be more readily understood by reference to 

 the annexed outlines, which are taken from a cast of one of the 

 skulls obtained by Mr. Pentland. 



Dr. Goddard suggested that the deformity observable in this 

 series of crania, might have been produced by the action of rotary 

 bandages alone, without the use of splints or compresses. Dr. 

 Morton admitted the possibility of this result in some of the heads, 

 but thought that in others there was satisfactory evidence of the 

 use of the splint or compress, especially on the os frontis.
