  The 
  Relation

  the 
  Sounds 
  of 
  Fog

  Two 
  kinds 
  of 
  areas 
  of 
  inaudibility 
  of 
  fog 
  signals 
  are 
  ditferentiated 
  under 
  the 
  names 
  of 
  niunt- 
  

   umbral 
  and 
  pseudumbral, 
  and 
  each 
  is 
  characterized. 
  The 
  author 
  believes 
  that 
  other 
  sounds 
  

   tlian 
  those 
  of 
  tlie 
  neighboring 
  fog 
  signal 
  may 
  be 
  projected 
  from 
  various 
  directions 
  into 
  any 
  

   of 
  tliose 
  areas 
  of 
  inaudibility 
  of 
  the 
  sounds 
  of 
  the 
  signal, 
  and 
  that 
  echoes 
  of 
  the 
  latter 
  m:iy 
  also 
  

   lie 
  projected 
  ir,to 
  any 
  of 
  those 
  areas. 
  Possible 
  danger 
  to 
  shipiiing 
  in 
  the 
  latter 
  cases 
  is 
  pointed 
  

   out.
