  The 
  work 
  as 
  above 
  quoted, 
  contains 
  a 
  full 
  account 
  of 
  the 
  occurrence 
  

   of 
  this 
  gas 
  in 
  various 
  parts 
  of 
  the 
  State. 
  Subsequent 
  researches 
  have 
  

   shed 
  very 
  little 
  further 
  light 
  upon 
  the 
  question 
  of 
  its 
  origin. 
  "We 
  have 
  

   indeed 
  the 
  negative 
  evidence 
  that 
  in 
  the 
  western 
  part 
  of 
  the 
  State, 
  

   where 
  its 
  evolution 
  is 
  most 
  abundant, 
  it 
  does 
  not 
  arise 
  from 
  the 
  decom- 
  

   position 
  of 
  coal 
  ; 
  and 
  Mr. 
  Hall 
  asserts 
  that 
  " 
  the 
  amount 
  of 
  organic 
  

   matter, 
  both 
  animal 
  and 
  vegetable, 
  known 
  in 
  this 
  rock, 
  (Medina 
  sand- 
  

   stone,) 
  is 
  so 
  exceedingly 
  small, 
  that 
  it 
  could 
  scarcely 
  be 
  supposed 
  to 
  

   give 
  rise 
  to 
  the 
  constant 
  emission 
  of 
  this 
  gas. 
  The 
  impervious 
  nature 
  

   of 
  the 
  lower 
  part 
  of 
  the 
  mass, 
  and 
  the 
  absence 
  of 
  fossils 
  in 
  the 
  next 
  

   rock 
  below, 
  would 
  preclude 
  the 
  idea 
  of 
  its 
  origin 
  in 
  that 
  direction, 
  as 
  

   there 
  are 
  no 
  disturbances 
  know 
  in 
  the 
  district."

  One 
  of 
  these 
  gas 
  springs 
  is 
  noticed 
  by 
  Prof. 
  Mather, 
  as 
  occurring 
  at 
  

   Haverstraw, 
  in 
  Rockland 
  county.

  Mr. 
  Hall 
  remarks, 
  " 
  that 
  there 
  is 
  scarcely 
  a 
  doubt 
  but 
  the 
  Canoga 
  

   springs 
  have 
  their 
  origin 
  along 
  a 
  line 
  of 
  fault 
  or 
  fracture 
  in 
  the 
  strata. 
  

   Those 
  Chateaugay, 
  in 
  Franklin 
  county, 
  are 
  near 
  the 
  junction 
  of 
  the 
  

   granite 
  and 
  Potsdam 
  sandstone, 
  and 
  in 
  the 
  calciferous 
  sandrock."

  In

  appendix 
  to 
  Fownes' 
  Chemistry, 
  

   1845,

  edition, 
  I 
  find 
  a 
  table 
  of 
  the 
  anhydrous 
  ingredients 
  in 
  one 
  

   pound 
  Troy 
  of 
  the 
  water 
  of 
  this 
  spring, 
  by 
  Dr. 
  Schweitzer. 
  The 
  num- 
  

   ber 
  of 
  substances 
  there 
  given 
  is 
  much 
  larger 
  than 
  that 
  heretofore 
  de- 
  

   tected 
  in 
  these 
  waters 
  by 
  other 
  chemists. 
  Among 
  these 
  are, 
  carbonate 
  

   of 
  strontia, 
  protocarbonate 
  of 
  manganese, 
  sulphate 
  of 
  potassa, 
  nitrate
