OF THE MICMAC SKULL CAMERON." 13 



dent during life. However, this apparently did not occur at 

 the time of the accident which caused the death of the indivi- 

 dual as the bones showed no recent fracture, nor even signs of 

 osseous thickening that would indicate an injury even more 

 remote. This distortion of the nasal bones did not effect the 

 nasal index in any way.. The nasal width was found to be 

 exactly half the nasal height, the index thus being 50, and 

 placing the skull in the mesorrhine group. Compare this with 

 the index of 54.9 recorded by the author in a Melanesian 

 skull (^) which was thus markedly platyrrhine, and indicated 

 a very wide nasal aperture, which is, of course, the condition 

 in all the lower races of modern mankind. The nasal index of 

 the Micmac skull proved to be the same as that of the Mon- 

 golian type of skull, which is given by Flower (^) as averaging 

 50, and it is further of interest to note that this figure is inter- 

 mediate between the lowest types and the British type of 

 skull where the average index was found b}' the same observer 

 to be 46 (leptorrhine). 



The Alveolar or Gnathic Index.— The basi-nasal and the 

 basi-alveolar lengths proved to be exactly the same, namely 

 104 mm., so that the alveolar index was obviously 100, thus 

 placing the skull in the middle of the mesognathous class (^) 

 (Flower)( ^). The projection of the jaws proved however, to be 

 almo.st entirely of the subnasal yarietj'' which corresponds 

 to the condition met with in the Andamanese skulK"). The 

 upper part of the face certainly looked definitely orthogna- 

 thous. The most significant fact regarding this index w^as 

 that it practically corresponded to the figure for the average 

 Mongolian type of skull, thus providing one more feature of 

 affinity between the North American Indian and the Mongo- 

 lian. 



The Stephano-Zygomatic Index. — This index was calculated 

 as 83.3, the result being that the zygomatic arches were to- 

 lerably well exposed when the skull was viewed from above,
