If  salicylic  acid  be  present  in  notable  quantities  the  residue  upon 
the  watch  glass  will  be  distinctly  crystalline ;  if  but  small  quanti- 
ties are  present,  the  residue  will  have  the  appearance  of  small  oily 
drops  arranged  in  a  circle  near  the  circumference  of  the  watch  glass. 
The  addition  of  a  few  drops  of  water  and  a  drop  of  a  dilute  solution  ot 
ferric  chloride  (a  dilute  solution  of  ammonio-ferric  alum  is  preferred 
by  some)  will  develop  the  characteristic  purple  color  of  ferric  sali- 
cylate, which  is  positive  evidence  of  the  presence  of  salicylic  acid. 
If  a  flesh-colored  precipitate  is  obtained  in  this  test  instead  of  a 
violet  coloration,  it  is  proof  of  the  presence  of  benzoic  acid,  the  pro- 
cesses for  the  extraction  of  these  principles  being  identical. 
When  the  liquid  which  is  to  be  tested  for  salicylic  acid  contains 
tannin,  it  will  be  necessary  to  change  the  preliminary  manipulation 
somewhat,  as  tannin  would  be  extracted  by  the  ether,  and  thus  ob- 
scure the  ferric  salicylate  reaction.  In  cases  of  this  kind,  the  liquid, 
instead  of  being  acidulated  with  sulphuric  acid  at  the  outset,  is 
treated  with  solution  of  lead  subacetate,  which  precipitates  tannin, 
coloring  principles,  etc.  It  is  then  filtered,  and  sufficient  sulphuric 
acid  is  added  to  the  filtrate  to  precipitate  the  excess  of  lead  and 
render  it  slightly  acid.  After  filtering  out  the  insoluble  lead  sul- 
phate the  liquid  is  treated  according  to  the  foregoing  directions.
