  Evidences 
  of 
  the 
  thoroughly 
  static 
  character 
  of 
  these 
  phenom- 
  

   ena 
  are 
  abundant, 
  I 
  mention 
  : 
  solid 
  isothermal 
  100°, 
  first 
  

   series 
  (not 
  given 
  above), 
  where 
  I 
  waited 
  from 
  50 
  m 
  to 
  100 
  m 
  at 
  a 
  

   pressure 
  below 
  the 
  solidifying 
  point 
  of 
  the 
  liquid, 
  without 
  ob- 
  

   taining 
  fusion, 
  whereas, 
  after 
  this 
  fusion 
  is 
  completed 
  between 
  

  

  101 
  m 
  and 
  112 
  m 
  with 
  only 
  slightly 
  further 
  reduction 
  of 
  pressure 
  ; 
  

   liquid 
  isothermal 
  100°, 
  second 
  series 
  (given 
  above 
  § 
  19, 
  and 
  

   chart 
  § 
  22), 
  where 
  I 
  waited 
  from 
  47 
  m 
  to 
  121 
  m 
  at 
  a 
  pressure 
  

   greater 
  than 
  that 
  at 
  which 
  the 
  solid 
  fuses, 
  without 
  obtaining 
  

   solidification, 
  whereas 
  this 
  sets 
  in 
  at 
  once 
  between 
  121 
  m 
  and 
  

   122 
  m 
  , 
  when 
  the 
  pressure 
  interval 
  is 
  only 
  slightly 
  increased 
  ; 
  

   solid 
  isothermal 
  130°, 
  second 
  series, 
  where 
  I 
  wait 
  from 
  86 
  m 
  to 
  

   96 
  m 
  at 
  a 
  pressure 
  below 
  the 
  solidifying 
  point 
  without 
  change 
  

   of 
  volume 
  or 
  fusion 
  whatever, 
  etc. 
  If 
  high 
  temperature 
  con- 
  

   ditions 
  are 
  unfavorable 
  to 
  volume 
  lag, 
  this 
  evidence 
  and 
  much 
  

   else 
  which 
  I 
  might 
  add, 
  is 
  accentuated. 
  

  

  I 
  have 
  already 
  pointed 
  out* 
  that 
  it 
  is 
  a 
  phenomenon 
  inher- 
  

   ent 
  in 
  the 
  passage 
  from 
  one 
  molecular 
  condition 
  to 
  another,
