CRUISE OF STEAMER CORWIN IN THE ARCTIC OCEAN. 



skulls, which do not as a rule come up to the 90° of Jupiter Tonans or of Cuvier, in spite of the 

 boasted intelligence of that nationality.

In none of the skulls of the collection is there ob.servable the heavy supercili.iry ridges alleged 

 to be common in lower races, bat which exist in many of the best-formed European crauiii — shall 

 we say as anomalies or as individual variations'? Nor is the convexity of the squanio-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 tlie 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, 

 Broca, Aitken, and Meigs: 



Cubic ceiitinaeters. 



Australian 1,228 



Polynesian 1,230 



Hottentot 1,230 



Mexican 1,296 



Malay 1, 328 



Ancient Peruvian 1,361 



French 1,403 to 1,461 



German 1, 448 



English 1,572 



An average of the Eskimo skulls, 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 Fren(!h or of the Germans. None of 

 tliem, 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.
