  of 
  those 
  functions, 
  are 
  greater, 
  and 
  involve 
  a 
  

   superior 
  number 
  and 
  quality 
  of 
  powers 
  than 
  

   those 
  resulting 
  from 
  the 
  change

  of 
  Cuvier's

  divisions)

  Accordingly, 
  Professor 
  Owen 
  has 
  attempted 
  

   to 
  found 
  a 
  system 
  of 
  classification 
  on 
  the 
  

   degrees 
  of 
  cerebral 
  development, 
  as 
  being 
  the 
  

   anatomical 
  feature 
  which 
  on 
  the 
  whole 
  stands 
  

   in 
  the 
  most 
  governing 
  relation 
  to 
  other 
  

   peculiarities 
  of 
  structure. 
  This 
  proposal 
  has 
  

   been 
  vehemently 
  contested 
  ; 
  but 
  the 
  contest 
  

   seems 
  to 
  have 
  turned 
  on 
  a 
  point 
  not 
  really 
  

   vital 
  to 
  the 
  question. 
  Objectors 
  do 
  but 
  aim 
  

   at 
  proving 
  that

  leading 
  divisions 
  in 
  the
