  been 
  destroyed 
  in 
  very 
  recent 
  times. 
  But 
  

   these 
  have 
  been 
  extinctions 
  effected 
  through 
  

   the 
  agency 
  of 
  Man. 
  What 
  is 
  now 
  proved 
  

   is 
  that 
  a 
  whole 
  group 
  or 
  fauna 
  of 
  great 
  

   quadrupeds 
  have 
  utterly 
  perished 
  since 
  Man 
  

   appeared. 
  And 
  the 
  causes 
  of 
  this 
  destruc- 
  

   tion 
  seem 
  to 
  have 
  been 
  of 
  the 
  same 
  kind 
  

   as 
  the 
  causes 
  which 
  in 
  all 
  former 
  ages 
  had 
  

   produced 
  similar 
  results 
  — 
  viz., 
  great 
  changes 
  

   in 
  the 
  climates 
  of 
  the 
  globe, 
  and 
  great 
  

   movements 
  affecting 
  the 
  configuration 
  of 
  its 
  

   surface. 
  In 
  these 
  last 
  circumstances 
  lies 
  the 
  

   real 
  stress 
  of 
  the 
  evidence 
  derived 
  from 
  the 
  

   new 
  discoveries. 
  It 
  is 
  conceivable 
  that 
  old 
  

   kinds 
  of 
  Elephant 
  and 
  Rhinoceros 
  may 
  

   have 
  roamed 
  over 
  Northern 
  Europe 
  when 
  

   its 
  surface 
  and 
  its 
  climate 
  were 
  the 
  same 
  as
