356 Morton’s Crania Americana. 
If the anterior lobe manifest the intellectual faculties—the mid- 
dle lobe, the propensities common to man with the lower animals— 
and the posterior lobe, the domestic and social affections ; and if 
size influence power of manifestation—the result will be that in 
the native American, intellect will be feeble—in the European, 
strong ;—in the American, animal propensity will be very great— 
in the European, more moderate ;—while in the American, the 
domestic and social affections will be feeble, and in the European, 
powerful. We do not state these as established results ; we use 
the cuts only to illustrate the fact that the native American and 
the European brains differ widely in the proportions of their 
different parts ;* and the conclusion seems natural, that if differ- 
ent functions be attached to different parts, no investigation can 
deserve attention which does not embrace the size of the differ- 
ent regions, in so far as this can be ascertained. 
We have entered more minutely into the reasons why we re- 
gard these measurements as important, because we conceive that 
the distinguishing excellence of Dr. Morton’s work consists in 
his having adopted and followed out this great principle. It 
appeared necessary to dwell upon it at some length, also, be- 
cause Professor Tiedemann, in his comparison of the European 
with the Negro brain, has entirely neglected it, and in conse- 
quence has arrived at physiological conclusions which we re- 
gard as at variance with the most certain psychological facts, 
viz. He says that “there is undoubtedly a very close connec- 
tion between the assoLure size of the brain and the INTEL- 
LECTUAL POWERS AND FUNCTIONS of thé mind ;” and _proceed- 
ing on this principle, he compares the weight of the whole 
brain, as ascertained in upwards of fifty Europeans of different 
ages and countries, with its weight in several Negroes, exam- 
ined either by himself or others. He gives extensive tables 
showing the weight of the quantity of millet seed necessary to 
fill Ethiopian, Caucasian, Mongolian, American, and Malay skulls; 
and adds that “ the cavity of the skull of the Negro in general, 
is not smaller than that of the European and other human races.’ 
The inference which he draws, is that intellectually and morally, 
as well as anatomically, the Negro is naturally on a par with the 
Paes ewer 
* From inspecting numerous crania of both races, we cannot doubt of the gen- 
eral truth of this proposition.
