โฆ Synopsis
While the writer was engaged in examining the Eskimo crania brought back by the Canadian Arctic Expedition of 1913-1918, he noticed that the average cephalic index exhibited a slightly higher result in the female than in the male crania. The actual figures were 73.07 for the females and 72.08 for the males. HrdliEka's valuable catalogue (3) of the Eskimo crania in the United States National Museum was not available to him at the time he wrote his report(1) on the above cranial material. He therefore did not attach any importance to this apparent sexual difference at the time. When the catalogue came into his hands, however, he decided to investigate this point, and found to his surprise that every tribal group, six in number, represented therein registered a higher index in the females than in the males, except the Baffin Land group. I n the latter the index was higher in the males than in the females, but, as this result was founded upon the examination of only four male and five female crania, it was clear that much larger numbers would have had to be utilized to furnish anything like a true sexual comparison.
