  of 
  magnesia

  chloride 
  of 
  ammonium 
  ; 
  which 
  are 
  rarely 
  met 
  with 
  

   under 
  these 
  circumstances. 
  It 
  is 
  to 
  be 
  regretted 
  that 
  the 
  fluid 
  quantity 
  

   of 
  water 
  analyzed 
  by 
  Dr. 
  Schweitzer 
  is 
  not 
  stated. 
  The 
  whole 
  analysis 
  

   differs 
  greatly 
  from 
  those 
  previously 
  published. 
  

  

  Empire 
  Spring, 
  Saratoga. 
  This 
  is 
  another 
  of 
  those, 
  so 
  called, 
  new 
  

   discoveries 
  which 
  are 
  every 
  few 
  years 
  made 
  at 
  Saratoga. 
  That 
  the 
  

   proprietors 
  of 
  these 
  new 
  springs 
  should 
  find 
  it 
  to 
  their 
  interest 
  to 
  laud 
  

   their 
  waters 
  as 
  possessing 
  remarkable 
  properties, 
  is 
  not 
  perhaps 
  sur- 
  

   prising. 
  But 
  a 
  little 
  reflection 
  must 
  satisfy 
  us 
  that 
  there 
  can 
  be 
  no 
  great 
  

   difference 
  in 
  the 
  composition 
  of 
  springs 
  which 
  undoubtedly 
  have 
  a 
  com- 
  

   mon 
  origin. 
  

  

  The 
  spring 
  which 
  has 
  received 
  the 
  above 
  name, 
  was, 
  it 
  is 
  said, 
  par- 
  

   tially 
  made 
  known 
  in 
  1S46, 
  under 
  that 
  of 
  New 
  Congress 
  Spring. 
  Ac- 
  

   cording 
  to 
  the 
  analysis 
  of 
  Dr. 
  Emmons, 
  the 
  saline 
  matters 
  contained 
  in 
  

   one 
  pint 
  of 
  this 
  water, 
  are 
  as 
  follows 
  : 
  

  

  Chloride 
  of 
  sodium, 
  

   Bicarbonate 
  of 
  soda, 
  

   Bicarbonate 
  of 
  lime, 
  

   Bicarbonate 
  of 
  magnesia, 
  

   Hydriodate 
  of 
  soda, 
  

  

  33'71 
  grains.

  The 
  peculiarities 
  of 
  this 
  water 
  are 
  said 
  to 
  be 
  the 
  remarkably 
  large 
  pro- 
  

   portion 
  of 
  hydriodate 
  of 
  soda, 
  and 
  its 
  freedom 
  from 
  any 
  salt 
  of 
  iron. 
  

   I 
  am 
  apprehensive, 
  however 
  that 
  the 
  proportion 
  of 
  iodine 
  may 
  be 
  over- 
  

   stated 
  in 
  the 
  above 
  table, 
  as 
  I 
  have 
  been 
  unable 
  to 
  detect 
  its 
  presence 
  

   by 
  the 
  most 
  delicate 
  tests, 
  either 
  in 
  the 
  raw 
  water, 
  or 
  in 
  a 
  portion 
  par- 
  

   tially 
  reduced 
  by 
  evaporation.

  HYDROUS 
  SULPHURIC

  Under 
  the

  Sulphuretted 
  Hydrogen, 
  I 
  have 
  already 
  introduced 
  

   some 
  remarks 
  in 
  regard 
  to 
  the 
  occurrence 
  of 
  this 
  acid 
  in 
  a 
  dilute 
  form, 
  

   in 
  Western 
  New- 
  York.
