  question, 
  not 
  only 
  that 
  a 
  hot 
  saturated 
  brine 
  will 
  deposit 
  salt 
  

   when 
  cooled, 
  but 
  that 
  the 
  developing 
  crystals 
  in 
  growing 
  exert 
  

   a 
  lateral 
  pressure 
  sufficient 
  to 
  permit 
  continued 
  growth 
  even 
  

   against 
  opposing 
  external 
  forces. 
  

  

  Some 
  of 
  the 
  stages 
  of 
  growth 
  of 
  the 
  crystals 
  in 
  this 
  experi- 
  

   ment 
  are 
  given 
  in 
  tigs.

  Later 
  the

   began 
  to

   the

  of 
  the 
  second 
  run, 
  after 
  the 
  first 
  puncture 
  and 
  

   before 
  the 
  second 
  one, 
  which 
  ended 
  the 
  experiment.
