40) CRUISE OF STEAMER CORWIN IN THE ARCTIC OCEAN.

boasted intelligence of that nationality.

In none of the skulls of the collection is there observable the heavy superciliary ridges alleged 
to be common in lower races, but which exist in many of the best-formed European crania—shall 
we say as anomalies or as individual variations? Nor is the convexity of the squamo-parietal 
suture such as characterizes the low-typed cranium of the chimpanzee or of the Mound Builder. 
On the contrary, the orbits are cleanly made and the suture is well curved. Besides, a low degree 
of intelligence is not shown by observing the index of the foramen magnum, which is about the 
same as that found in European crania; and the same may be said of the internal capacity of the 
cranium. To illustrate the latter remark is appended a tabular statement made up from Welcker, 
Broea, Aitken, and Meigs:

An average of the Eskimo skulls, some of which measure as much as 1,650 and 1,715 ¢. ¢., 
will show the brain capacity to be the same as that of the Irench 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 ¢, ¢., and the other the unprecedented measurement of 
1,920 ¢. ¢.
