Europeans. Thus, while the largest Teutonic skull 

 in Dr. Davis' collection is 112'4 cubic inches, there is 

 an Araucanian of 115*5, an Esquimaux of 113*1, 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
