In taking these two indices I find a singular descrepancy. 
While Kollmann index more or less coincides with that of the 
Esquimaux: that of Broca shows a great difference.

The reason of this must lie inte greater distance, in the 
Esquimaux, from the naso-frontal suture to the ophryo, which 
in the Chilians is relatively short (10 mm.); although taking the 
much greater zygomatic diameter of the former into consider- 
ation (137 mm. as against 129 mm.) this does not prima facie 
seem probable, more especially as in the naso-malar index the 
two races is very slight.

Thus we see that in the principal skull measurements, these 
two races, although separated by a whole continent; are almost 
identical. 
This is the more remarkable when we consider that the 
Esquimaux has been supposed to have few or no affinities with 
any other knorw race. 
But not alone in these points do great similarities occur.
