Europeans. Thus, while the largest Teutonic skull 
in Dr. Davis’ collection is 112-4 cubic inches, there is 
an Araucanian of 1155, an Esquimaux of 1131, a 
Marquesan of 110°6, a Negro of 105°8, and even an 
Australian of 104°5 cubic inches. We may, there- 
fore, fairly compare the savage with the highest 
European on the one side, and with the Orang, Chim- 
panzee, or Gorilla, on the other, and see whether 
there is any relative proportion between brain and 
intellect. 
Range of intellectual power in Man.—First, let ‘us 
consider what this wonderful instrument, the brain, is 
capable of in its higher developments. In Mr. Galton’s 
interesting work on ‘ Hereditary Genius,” he remarks 
on the enormous difference between the intellectual 
power and grasp of the well-trained mathematician 
or man of science, and the average Englishman. The 
number of marks obtained by high wranglers, is often 
more than thirty times as great as that of the men 
at the bottom of the honour list, who are still of fair 
mathematical ability ; and it is the opinion of skilled 
examiners, that even this does not represent the full 
difference of intellectual power. If, now, we descend 
to those savage tribes who only count to three or five, 
and who find it impossible to comprehend the addition 
of two and three without having the objects actually 
before them, we feel that the chasm between them and 
the good mathematician is so vast, that a thousand to 
one will probably not fully express it. Yet we know 
that the mass of brain might be nearly the same in
