“3d. The Malays embrace Malays proper and Polynesians, 
thirteen of the former and five of the latter; and the mean of 
each presents buta fractional difference from the mean of all. 
“Ath. 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. Seapacting the American race, I have nothing to add, 
excepting 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. 
Peruvians collectively, 76 cub. inch. 
Toltecan nations, ¢ Mexicans collectively, 79 0. 
' Barbarous tribes, as per table, 82 — do. 
“ An interesting question remains to be solved, viz. the relative 
ion 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 ieisage nor adequate materials.” p. 261. 
We now add Dr. Morton’s statement in his prefatory letter to 
Mr. Phillips. “Tam 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 am honor to the country, and asa 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 Hoe obtained by Dr. Morton. Tiede- 
mann gives the weight of only’four Negro brains. ‘ The average European,” he 
says, “runs from 3 lbs. 2.0z. to 4 Ibs.6 oz. ; while re average of the four Negro bra rains 
rises to only 3 Ibs. 50z. 1 dr.; or 3 oz. shan 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 is tated s linear dimensions of the European and Negro 
brain also contradict his th of equality, and are in harmony with Dr. Morton's
