  Mankind. 
  According 
  as 
  we 
  may 
  have 
  made 
  

   one 
  or 
  other 
  of 
  these 
  great 
  branches 
  of 
  inquiry 
  

   our 
  favourite 
  pursuit, 
  we 
  may 
  be 
  disposed 
  

   to 
  place 
  a 
  different 
  estimate 
  on 
  their 
  com- 
  

   parative 
  value. 
  But 
  perhaps 
  we 
  shall 
  not 
  go 
  

   far 
  wrong 
  if 
  we 
  arrange 
  them 
  in 
  the 
  order 
  

   here 
  given, 
  as 
  the 
  order 
  in 
  which 
  they 
  stand 
  

   relatively 
  to 
  the 
  directness 
  and 
  certainty 
  of 
  

   the 
  testimony 
  they 
  afford. 
  

  

  One 
  distinction, 
  however, 
  it 
  is 
  important 
  

   to 
  bear 
  in 
  mind. 
  Chronology 
  is 
  of 
  two 
  kinds, 
  

   — 
  first, 
  Time 
  measurable 
  by 
  years, 
  — 
  and 
  

   secondly, 
  Time 
  measurable 
  only 
  by 
  an 
  

   ascertained 
  order 
  or 
  succession 
  of 
  events, 
  

   The 
  one 
  may 
  be 
  called 
  Time-absolute, 
  the 
  

   other 
  Time-relative. 
  Now, 
  among 
  all 
  the 
  

   sciences 
  which 
  afford 
  us 
  evidence 
  on 
  the
