374 Morton's Crania Americana. 



"3d. The Malays embrace Malays proper and Polynesians, 

 thirteen of the former and five of the latter ; and the mean of 

 each presents but a fractional difference from the mean of all. 



" 4lh. The Ethiopians were all unmixed negroes, and nine of 

 them native Africans, for which I am chiefly indebted to Dr. 

 McDowell, formerly attached to the colony at Liberia.* 



" 5th. Respecting the American race, I have nothing to add, 

 exceptmg the striking fact that of all the American nations, the 

 Peruvians had the smallest heads, while those of the Mexicans 

 were something larger, and those of the barbarous tribes the 



largest of all, viz. 



C Peruvians collectively, 76 cub. inch. 



Toltecan nations, < Mexicans collectively, 79 do. 



^ Barbarous tribes, as per table, 82 do. 



" An interesting question remains to be solved, viz. the relative 

 proportion of brain in the anterior and posterior chambers of the 

 skull in the different races ; an inquiry for which I have hitherto 

 possessed neither sufficient leisure nor adequate materials." p. 261. 



We now add Dr. Morton's statement in his prefatory letter to 

 Mr. Phillips. " I am free to acknowledge," says he, " that there 

 is a singular harmony between the mental character of the In- 

 dian, and his cranial developments, as explained by phrenology." 



Our readers will discover in the length and minuteness of this 

 article, the great value which we attach to Dr. Morton's work. 

 We regard it as an honor to the country, and as a proof of talent, 

 patience, and research in himself, which place him in the first 

 rank among natural philosophers. We rejoice to see that he does 

 " not, even now, consider his task as wholly completed ;" but 

 hopes to publish a " supplementary volume, in which it will fur- 



* Dr. Morton states the mean internal capacity of the European, or Caucasian 

 skulls, to be 87, and of the Ethiopian, or Negro race, to be 78 cubic inches. We 

 observe that Dr. Andrew Combe, in his " Remarks on the Fallacy of Professor 

 Tiedemann's Comparison of the Negro brain and intellect with those of the Euro- 

 pean," arrives at results coinciding with those obtained by Dr. Morton. Tiede- 

 mann gives the weight of only four Negro brains. " The average European," he 

 says, " runs from 3 lbs. 2 oz. to 4 lbs. 6 oz ; while the average of the four Negro brains 

 rises to only 3 lbs. 5 oz. 1 dr ; or 3 oz. above the lowest European averages ; and the 

 highest Negro falls 5 oz. short of the highest average European, and no less than 

 10 oz. short of Cuvier's brain." Phren. Journ., Vol. XI. We have already 

 shown, p. 357, that Tiedemann's linear dimensions of the European and Negro 

 brain also contradict his theory of equality, and are in harmony with Dr. Morton's 

 results.
