  opinion, 
  be 
  explained, 
  except 
  by 
  violent 
  and 
  

   sudden 
  action 
  since 
  or 
  during 
  the 
  period 
  of 
  

   their 
  entombment. 
  Great 
  caves, 
  packed 
  closely 
  

   from 
  floor 
  to 
  roof 
  with 
  the 
  bones 
  of 
  the 
  

   Hippopotamus 
  and 
  Rhinoceros 
  ; 
  other 
  caves, 
  

   equally 
  full 
  of 
  the 
  bones 
  of 
  extinct 
  Oxen, 
  

   are 
  proofs 
  of 
  some 
  diluvial 
  action 
  of 
  which 
  

   Man 
  has 
  had 
  no 
  experience 
  in 
  historic 
  times. 
  

   But, 
  even 
  allowing 
  for 
  the 
  greater 
  activity 
  of 
  

   geological 
  causes, 
  the 
  time 
  required 
  for 
  such 
  

   changes 
  of 
  climate 
  has 
  in 
  all 
  probability 
  been 
  

   very 
  great. 
  And 
  when 
  we 
  consider 
  that 
  

   many 
  of 
  these 
  evidences 
  of 
  Geology 
  apply 
  to 
  

   the 
  New 
  World 
  as 
  well 
  as 
  to 
  the 
  Old, 
  we 
  can- 
  

   not 
  fail 
  to 
  see 
  that 
  the 
  proofs 
  of 
  a 
  very 
  high 
  

   antiquity 
  for 
  the 
  Human 
  Race 
  are 
  proofs 
  of 
  

   a 
  cumulative 
  character, 
  gathered 
  along 
  several
