An average of the Eskimo skull, some of which measure as much as 1,650
and 1,715 c.c., will show the brain capacity to be the same as that of
the French or of the Germans. None of them, however, approaches the
anomalous capacities of two Indian skulls on exhibition at the Army
Medical Museum, one of which shows 1,785 c.c., and the other the
unprecedented measurement of 1,920 c.c.

If the foregoing means for estimating the mental grasp and capacity for
improvement be correct, then we must accord to the most northern nation
of the globe a fair degree of brain energy--potential though it be.
Aside from the mere physical methods of determining the degree of
intelligence, it is urged by some writers, among them the historian
Robertson, that tact in commerce and correct ideas of property are
evidence of a considerable progress toward civilization. The natural
inference from this is that they are tests of intellectual power, since
mind is a combination of all the actual and possible states of
