GENESIS OF MAN, INTELLECTUALLY

But although in these respects the corre- 

 spondence in space does not seem to have been 

 extended with the progress of civilization, yet 

 in those far more indirect and complicated ad- 

 justments which, as involving time relations of 

 force and cause, depend largely on the aid of 

 the cerebrum, the civilized man surpasses the 

 savage to a much greater extent than the savage 

 surpasses the wolf or lion. " By combining his 

 own perceptions with the perceptions of others 

 as registered in maps," the modern " can reach 

 special places lying thousands of miles away over 

 the earth^s surface. A ship, guided by compass 

 and stars and chronometer, brings him from the 

 antipodes information by which his purchases

 exhibited in barbarians and lower animals, it was observed 

 that a party of Samoyeds will travel in a direct line from one 

 point to another over trackless fields of ice, even on cloudy 

 nights, when there is accordingly nothing whatever that is 

 visible to guide their course. It would be too much to assert 

 that this faculty is utterly lost in civilized man, so that a tem- 

 porary recurrence to the conditions of barbaric life might not 

 revive it ; but even if retained at all, it is certainly kept quite 

 in abeyance.
