Dr Morton gives the result of the measurement of twenty- 

 three adult skulls of the pure Inca race. " The mean of the 

 internal capacity is 73 cubic inches, which is probably lower 

 than that of any other people now existing, not excepting the 

 Hindoos." The mean of the anterior chamber is 32, of the 

 posterior 42, of the coronal region 12 cubic inches. The 

 highest measure of the coronal region is 20.5, and the smallest 

 9.25 cubic inches. The mean facial angle is 75 degrees. The 

 heads of nine Peruvian children appear to be nearly, if not 

 quite, as large as those of children of other nations at the same 

 age. P. 133. 



The small size of the brains of this race, compared with that 

 of the Europeans who invaded them, is in accordance with the 

 ease with which the former were overcome and retained in 

 subjection. The deficiency in the posterior region of the brain, 

 in which the organs of the domestic affections are situated, 

 corresponds with their feeble conjugal attachment and indif- 

 ference to the Uves of their children. The diameter from 

 constructiveness to constructiveness, is stated by Mr Phillips 

 to be 4.5 inches, and from ideality to ideality 5.1. These 

 organs give a talent for art, and are considerable. The same 

 measurements in the Naumkeagh, the race which occupied 

 New England, and whose skulls are still dug up near Boston 

 and Salem, and which never made any attainments in the arts, 

 are 4.1 and 4 inches, respectively. Dr Robertson, in his his- 

 tory of America, mentions that the modern Peruvian race was 

 distinguished for its extraordinary powers of concealment and 

 secrecy. Mr Phillips states the breadth from secretiveness to 

 secretiveness to be 5.6 inches, which is large ; the longitudinal 

 diameter is only 6.1. The region of combativeness also ap- 

 pears to be deficient in these skulls.
