  thoughtful 
  mind, 
  and 
  arouse 
  us 
  to 
  think 
  of 
  the 
  many 
  

   evolutions 
  that 
  have 
  taken 
  place 
  in 
  nature, 
  and 
  the 
  

   numerous 
  creatures 
  that 
  have 
  lived 
  and 
  disappeared 
  from 
  

   the 
  country 
  around 
  us, 
  and 
  to 
  speculate 
  on 
  their 
  descendants 
  

   that 
  are 
  now 
  present— 
  what 
  they 
  are, 
  and 
  what 
  they 
  in 
  turn 
  

   may 
  become.
