366 Dr. Dawsonh additional notes on 



investigations of the. naturalist when dealing with man. The 

 evidence which places beyond doubt the posthumous origin of the 

 distorsion in this Hochelaga skull is of the same nature as that 

 which has already been accepted in relation to an example reco- 

 vered from an Anglo-Saxon cemetery at Stone, in Buckingham- 

 shire. The forehead is flattened and greatly depressed on the 

 right side, and this recedes so far, owing to the distorsion of the 

 whole cranium, that the right external annular process of the 

 frontal bone is nearly an inch behind that of the left side. The 

 skull recedes proportionally on the same side throughout, with 

 considerable lateral development at the parietal protuberance, and 

 irregular posterior projection on the right side of the occiput. 

 The right superior maxillary and malar bones are detached from 

 the calvarium, but the nasal bones and the left maxillary remain 

 in situ, exhibiting, in the former, evidence of the well developed 

 and prominent nose characteristic of Indian physiognomy. The 

 bones of the calvarium, with one slight exception, have retained 

 their coherence, notwithstanding the great distorsion to which it 

 has been subjected, though in this example ossification has not 

 begun at any of the sutures. The exception referred to is in the 

 left temporal bone, which is so far partially displaced as to have 

 detached the upper edge of the squamous suture. Part also of 

 the base of the skull is wanting. 



" The posthumous origin of the distorsion of this skull is proved 

 beyond dispute on replacing the condyles of the lower jaw in ap- 

 position with the glenoid cavities, when it is found that, instead 

 of the front teeth meeting the corresponding ones of the upper 

 maxillary, the lower right and left incisors both impinge on the 

 first right canine tooth, and the remaining teeth are thereby so 

 displaced from their normal relation to those of the upper jaw, as 

 to preclude the possibility of their answering the purpose of 

 mastication — which their worn condition proves them to have 

 done, — had they occupied the same relative position during life. 



<' The extreme distorsion which this skull has undero-one is still 

 more apparent when looking on it at its base. The bone has 

 been fractured, and portions of it have become detached under 

 the pressure, while the mastoid processes are twisted obliquely, so 

 that the left one is upward of an inch in advance of the right. 



" The circumstances under which this Indian skull was found 

 tend to throw some light on the probable process by which its 

 posthumous malformation was eff'ected. It was covered by little
