  It 
  is 
  assumed 
  that 
  the 
  student 
  before 
  taking 
  up 
  geology 
  has 
  

   had 
  a 
  good 
  general 
  training 
  in 
  physics 
  and 
  chemistry, 
  without 
  

   which 
  no 
  proper 
  understanding 
  of 
  the 
  subject 
  can 
  be 
  had. 
  An 
  

   elementary 
  knowledge 
  of 
  zoology 
  and 
  botany 
  is 
  also 
  indispen- 
  

   sable.
