tions. In a few instances there is a well marked incisor crest. The 

 mean nasal index for eight males is 51, varying from 47 to 59; for the 

 seven females the mean is 53, the range being from 48 to 60. The 

 mean general index for the entire series is 52, thus just coming within 

 the mesorhine group. This also agrees with Prof. Turner's results, 

 but is considerably less than the figure- given by Hovelacque and 

 Herve, which is 54.9. 



In a great majority of skulls the canine fossae are deep, even in 

 some few examples cavernous. I am not able to detect any sexual 

 difference in this respect, the variation apparently bring wholly indi- 

 vidual. The alveolar process of the facial surface of the maxillary 

 bones has, as a rule, an impoverished, compressed appearance, so 

 that the eminences produced by the fangs of the teeth stand out in 

 relief; in many skulls they are so clean cut and well defined that the 

 exact course of the fangs of all the teeth can be made out. 



I have not taken the inter-malar breadth, but have made a com- 

 parative examination of the shape, size, etc., of the malar bones. On 

 the whole thev have the appearance of being slightly undersized. 

 They are not especially prominent, and have sharp, thin borders. In 

 the males the tubeix>sity is well defined and projecting; quite the 

 reverse is true of the females. The average bizygomatic diameter for 

 the entire series is 123 mm. There is considerable difference between 

 the two sexes; in the males the mean is 128 mm., maximum 134 

 mm., minimum 122 mm. In the females the mean is 118 mm., max- 

 imum 127 mm., minimum 109 mm. I have no measurement which 

 equals that of 140 mm. of Prof. Turner, while on the other hand I 

 can find nothing in his figures which compares with my minimum of 

 109 mm. This diameter comes from a female skull which is only 

 remarkable otherwise for its extreme amount of alveolar and dental 

 prognathism. 



For reasons already given I have begun both facial-height diam- 

 eters at nasion. The mean naso-alveolar length is 70 mm. The 

 average male length is 72 mm., maximum 77 mm., minimum 66 mm.; 

 the average for the females is 69 mm., maximum 75 mm., minimum 

 65 mm. The maximum length given by Turner is 68 mm. In seven 

 of the eight males the naso-mental length could be taken; this ranged 

 from no mm. to 119 mm., with an average of 115 mm. In the » \. □ 

 females the mean is 107 mm., with a maximum of 114 mm., and a 

 minimum of 96 mm. From the bizygomatic diameter and the naso- 

 alveolar length we get the index of the upper or true face. This 

 varies from 52 to 61, with a mean of 55 for the males and from 54 to 

 59 with mean of 57 for the females, thus making the average index
