The  Superiority  of  Artificial  Mineral  Waters. 
By  Enno  Sander. 
The  author  gave  the  origin  of  mineral  waters.  He  stated  that 
Meteoric  water  penetrates  the  earth's  crust  and  returning  to  the 
surface  loaded  with  materials,  creates  healing  springs,  and  that  they 
are  beneficial  only  at  their  source.  They  have  no  uniformity  of  com- 
position at  different  times,  and  are  easily  decomposed  by  various 
causes.  They  cannot  be  bottled  or  transported.  It  was  stated  that 
Dr.  F.  A.  Struve  constructs  apparatus  for  preparing  artificial  waters  j 
of  same  composition  as  the  natural  but  without  their  disposition 
to  degeneration,  and  that  scientists  of  all  countries  indorse  the  in- 
vention. On  the  other  hand  opposition  had  been  active  but  vain. 
The  author  said  that  there  is  necessity  for  pure  materials  and  stated 
artificial  waters  have  many  merits. 
The  Detection  of  Phenol  and  Cresotic  Acids  in  Salicylic 
Acid  and  its  Derivatives. 
By  H.  Engelhardt  and  H.  W.  Jones. 
The  Carletti  reaction  for  the  detection  of  phenol  in  salicylic  acid 
by  the  use  of  a  2  per  cent,  alcoholic  solution  of  furfurol  was  applied 
to  a  number  of  samples  of  salicylic  acid  and  its  derivatives.  The 
investigation  was  extended  to  discover  whether  this  reaction  is  also 
applicable  to  cresotic  acids  which  are  formed  during  the  process 
of  manufacture  of  salicylic  acid.  The  authors  found  that  the  cresotic 
acids  give  the  same  color-test  as  phenol  with  Carletti's  reaction, 
the  sensitiveness  being  even  greater  than  with  phenol.  Of  eighty 
samples  of  salicylic  acids  and  derivatives,  only  60  per  cent,  were 
found  free  from  contamination. 
Notes  on  Syrup  of  Hypophosphites  and  Syrup  of  Calcium 
Lactophosppiate. 
By  H.  W.  Jones. 
The  results  were  given  of  a  study  of  the  progressive  inversion 
taking  place  in  the  above  named  U.  S.  P.  syrups.  These  results, 
presented  in  the  form  of  curves,  showed  the  rate  and  extent  of 
this  inversion  in  Syrifp  of  Hypophosphites,  U.  S.  P.,  and  Syrup 
of  Calcium  Lactophosphate,  U.  S.  P.,  and  in  experimental  syrups 
containing  varying  amounts  of  either  mineral  or  organic  acids.  It
