pointed out the relative simplicity of the sulci and the 

 proportionate scarcity of secondary sulci when compan-d 

 with the European brain, and came to the conclusion that 

 these phenomena could not be wholly attributed to the sex 

 of the individual but constituted definite evidence of" tin- 

 racial inferiority of the Bushmen. 



At the same time one is bound to add to Marshall's 

 remarks, that those parts of the brain which we know to 

 have been markedly modified during the short nv.-nt 

 phases of human evolution (such, for example, as the 

 insular region and the areas around the parieto-occipital 

 and calcarine sulci) show little if any sign of inferiority in 

 comparison with the European brain. 0. C. 1339 B a.
