namely, the Atkans and (Eastern or) Unalaslikans. A coni])anson between 

 about the same number of Aleut crania, from the east and from the west, 

 shows the differences to be very trivial, if, indeed, they iU'e not such as would 

 disappear entirely with the examination of larger numbers of specimens, or 

 under mensuration by a different person. 



The crania supposed to belong to the era of Fishermen have not been 

 included above. Indeed, they are so imperfect, for the most part, that it 

 would be worse than rashness to attempt any generalizations upon them. 

 Comjiared vf'ith the twenty-two more modern crania referred to the epoch of 

 Hunters, they stand as follows: 



A slightly smaller capacity might have been expected of flie ancient 

 Fishermen, but it may not have existed, and, except for the few individuals 

 concerned, the above comparison does not prove it. The other differences 

 are of the most trivial description. 



The average facial angle among the Aleuts appears to have been 

 about 72°. 



In this connection, I may ventvire to remark that, while not a professed 

 craniologist, I have had the opportunity of examining a very large number 

 of aboriginal crania, and have become impressed with the great range of 

 variation which occurs in cases where no hybridity can be reasonably 

 asserted. It has appeared to me that while certain features, hardly defina- 

 ble, are to be recognized in crania from a single locality, yet when a com- 

 jDrehensive series of crania of any race to the number of several hundred are 

 examined, if the peoj)le be widely distributed in area, and subjected to vari- 

 ous conditions of diet and siirroun dings, it will invariably be found that 

 nearly all the so-called characteristic types of crania may be recognized, and
