The  bromine  being  in  excess  of  the  iodine,  it  has  in  Germany 
rightly  obtained  the  name  of  an  iodine  containing  bromine- water 
\_Iod-haltendes  Brom-wasser.~\ 
The  peculiarity  of  the  spring  does  not  rest,  however,  either 
upon  one  or  another  of  its  constituents,  but  upon  the  qualitative 
mixture  as  a  whole,  and  regarded  in  this  light  it  stands  quite 
alone.  The  greater  number  of  iodine  and  bromine  springs  are 
either  altogether  wanting  in  two  ingredients  which  play  an  im- 
portant part  in  the  Adelheid  spring,  viz.,  the  carbonate  of  soda 
and  the  carburetted  hydrogen,  or  they  contain  an  excess  of 
common  salt.  It  is  the  considerable  quantities  of  iodine,  bromine, 
carbonate  of  soda,  and  carburetted  hydrogen,  with  a  relatively 
low  adjunct  of  common  salt,  which  lends  to  this  spring  its  sim- 
ultaneous dissolving,  calming,  'anodyne  effect  on  the  mucous 
membrane  of  the  stomach  and  the  urinary  organs,  and  which 
belongs  to  no  other  bromine  or  iodine  spring. 
When  the  water  is  poured  into  a  glass,  a  multitude  of  bubbles 
of  gas  are  formed,  and  the  taste  is  nearly  that  of  weak  salted 
meat  broth.  It  excites  the  appetite,  increases  the  urinary  secre- 
tion, operates  powerfully  on  the  absorbents,  and  the  lymphatic
