Tobias  Venetian  liniment  consists,  according  to  the  "  Industrie* 
Blsetter,"  of  5  parts  ammonia  water,  2  parts  camphor,  5  parts  tinc- 
ture of  capsicum,  30  parts  alcohol  and  10  parts  of  water. 
The  detection  of  digitalin  in  forensic  analysis  is  connected  with 
great  difficulties.  By  the  method  of  Stas  and  Otto  the  acid  ethereal 
solution  yields  the  digitalin  as  a  resinous  mass,  and  a  small  portion 
enters  into  the  alkaline  solution.  Obtained  from  the  latter  it  cannot 
be  distinguished  from  delphinia  by  the  reactions  with  phosphoric  acid 
or  with  sulphuric  acid  and  bromine  water.  Obtained  from  the  for- 
mer solution  it  will,  in  rare  cases  only,  yield  the  red  coloration  with 
H2S04  and  bromine  water.  H.  Brunner,  therefore,  suggests  to  dis- 
solve the  residue  in  water,  add  some  dilute  solution  of  bile,  and  thei* 
concentrated  H2S04  until  the  liquid  assumes  the  beautiful  red  color 
of  Pettenkofer's  test  for  sugar,  the  latter  compound  being  separated 
from  the  digitalin  by  the  acid.  Other  glucosides  have  the  same  be- 
havior, but  the  author  thinks  this  reaction,  in  connection  with  th& 
physiological  action,  sufficient  proof  of  its  presence. — Ber.  d.
