212 COMPARATIVE PHYSIOLOGY OF THE BRAIN 



It is more probable that the relative number of the 

 nerve-endings or, more correctly speaking, the rela- 

 tive size of the circles of touch in the tip of the 

 tongue and the tip of the nose is determined by the 

 relatively small radius of curvature or the minimal 

 areal growth of these tips.
