SUPPLEMENTAL HISTORY OP MAN. 115 



difficulties in accounting for the phenomena of mind. 

 Organism, however, at least when limited to a sort 

 of modus operandi, by the Creator, on the immaterial 

 intellect, may eventually be shown to have some 

 general operation and influence in accounting for 

 those differences obvious to all between man and 

 man. This position, however, we conceive to be 

 by no means established, and to be pushed by its 

 supporters far beyond its probable legitimate 

 limits. 



Let us however without further speculation pro- 

 ceed to consider the facts discovered, and obser- 

 vations made by men of science on the brain, as 

 applicable to the division of the subject now under 

 consideration, namely, the specific differences be- 

 tween man and other animals. 



The ancients asserted that the brain of man is 

 absolutely larger than that of any other animal, and 

 there is probably no other exception to this rule 

 than in the elephant, and perhaps some of the larger 

 cetacea. All the larger animals with which we are 

 more intimately acquainted, have absolutely smaller 

 brains than man, as may be demonstrated by a 

 comparison of crania. 



Another method has been tried by later natu- 

 ralists in the investigation of this subject; they 

 have compared the proportion which the mass of 

 the brain bears to the entire body in men and brutes. 

 This comparison not being at first extended beyond 

 the domestic and more common animals with which 

 we are acquainted led to the proposition, that man,
