GLEA^s^INGS  FROM  THE  GERMAN  JOURNALS. 
By  Feaxk  X.  MoEEK,  Ph.  G. 
Test  for  Saccharin. — The  suspected  substance  is  extracted  from 
acidulated  solution  with  ether,  the  residue  after  the  evaporation  of  the 
solvent  is  heated  in  a  test  tube  with  thrice  its  bulk  of  resorcin  and  a 
few  drops  of  concentrated  HgSO^.  The  fluid  changes  to  yellow,  red, 
dark  green  and  then  effervesces,  through  liberation  of  SOg ;  the  fluid 
is  allowed  to  boil  up  several  times  and  then  set  aside  to  cool.  Ex- 
tracted with  water  containing  a  little  NaOH,  the  solution  if  saccharin 
was  present,  presents  a  pale  rose  tint  by  transmitted  light,  by  reflected 
light  a  beautiful  moss-green  fluorescence.  0.001  gm.  in  5  to  6  litres  of 
water  can  be  distinctly  detected. — Boernstein  inZtschr.f.  Anal.  Chem., 
1888,  167. 
Mel  Depuratum. — Becker  recommends  5  lbs.  crude  honey,  3  lbs. 
distilled  water  and  2  lbs.  alcohol  to  be  mixed,  allowed  to  stand  a  few 
days,  filtered,  the  alcohol  distilled  off  and  the  residue  evaporated. 
The  product  indefinitely  preserves  its  light  color. — Pharm.  Ztg.,  1888, 
313. 
Detection  of  Salicylic  Acid  in  Beverages  and  Foods. — Dr.  Ripper 
offers  the  following,  based  on  the  solubility  of  the  acid  in  a  mixture 
of  equal  volumes  of  ether  and  petroleum-ether,  in  which  extractive 
and  tannin  are  almost  insoluble.  50  cc.  of  the  liquid,  or  if  a  solid  a 
definite  quantity  mixed  with  water,  are  acidulated  with  5  cc.  of  dilute 
H2SO4,  and  agitated  with  50  cc.  mixed  ether  and  petroleum-ether  in  a 
separatmg  funnel ;  should  the  liquids  not  separate  readily,  addition  of  a 
little  alcohol  will  assist.  The  ethereal  solution  is  removed  and  agitated 
^ith  50  cc.  of  ether-saturated  water,  to  extract  acetic  acid  which  is
