THE EXTERNAL CONFIGUllATION 



length of one hemisphere backwards (usually the left, 



so far as I have observed) is very common in European 



brains." 



'* Viewed laterally the parietal region is salient ; the 



vertex is low and flattened, its highest point being placed 



far back ; the frontal 

 region is shallow." 

 .... "The tem- 

 poral lobe is narrow, 

 the line from its 

 point to the tip of 

 the posterior lobe 

 being very long ; the 

 curve formed by the 

 under border of the 

 Cerebrum, above 

 the Cerebellum, is 

 slighter, and its 

 direction more ob- 

 lique upwards and 

 backwards than in 

 the European brain, 

 owing apparently 

 to a want of down- 

 ward development
