  THE 
  ZOOLOGIST. 
  

  

  sufficient 
  to 
  say 
  that 
  he 
  accompanied 
  his 
  critical 
  views 
  by 
  a 
  

   constructive 
  theory 
  that 
  involved 
  great 
  difficulties, 
  and 
  that 
  will 
  

   certainly 
  be 
  abandoned. 
  

  

  The 
  controversy 
  between 
  these 
  two 
  great 
  men 
  has 
  been 
  of 
  

   considerable 
  advantage 
  ; 
  and 
  though 
  biologists 
  are, 
  many 
  of 
  

   them, 
  still 
  inclined 
  to 
  take 
  one 
  side 
  or 
  the 
  other, 
  yet 
  on 
  the 
  

   whole 
  they 
  have 
  profited, 
  inasmuch 
  as 
  they 
  have 
  thoroughly 
  

   realized 
  the 
  necessity 
  of 
  replacing 
  theory 
  and 
  argument 
  as 
  to 
  

   inheritance, 
  by 
  the 
  observation 
  of 
  facts. 
  

  

  Enough 
  has 
  been 
  said. 
  The 
  influence 
  of 
  Herbert 
  Spencer 
  on 
  

   Biology 
  has 
  been 
  great 
  and 
  good, 
  and 
  though 
  his 
  argumentations 
  

   will 
  many 
  of 
  them 
  be 
  sooner 
  or 
  later 
  replaced 
  by 
  demonstrated 
  

   facts, 
  yet 
  his 
  position 
  is, 
  as 
  we 
  said 
  at 
  the 
  outset, 
  an 
  historical 
  

   one, 
  between 
  Lamarck 
  and 
  the 
  modern 
  school.
