Pyrogallic  acid  stains  are  removed  from  linen  by  a  solution  of 
oxalic  acid  in  50  or  60  per  cent,  alcohol,  and  then  exposing  to  the 
direct  sunlight. — Pharm.  Gentralh.,  April  11,  p.  135. 
Presence  of  Large  Amount  of  Lime  in  Magnesia  Usta. — 
Calcined  magnesia  nearly  always  contains  a  trace  of  lime,  the  subcar- 
bonate  of  magnesia  being  rarely  free  from  it.  Marquardt  states  that  a 
larger  proportion  of  lime,  when  present,  is  easily  recognized  by  its 
characteristic  caustic  taste. — Pharm.  Centralh.,  April  11,  p.  137. 
Condensed  Milk. — A  writer  in  a  Cologne  paper  makes  the  follow- 
ing comparison  : 
Cond.  milk  of  Cham  contains  for  100  albuminates  63  fat  and  375  sugar. 
"  "    Kempfen         "      100         "  66      "      221  " 
Woman's  milk.  "      100         "  62     "       147  " 
The  amount  of  sugar  in  condensed  milk  is  thus  shown  to  be  double 
and  even  nearly  three  times  as  large  as  in  woman's  milk.  For  this 
reason  Prof.  Kehrer,  Dr.  Daly  and  other  physicians  consider  the  former 
as  not  only  not  beneficial,  but  even  injurious  to  infants,  the  sugar  being 
transformed  into  lactic  acid  in  the  intestines,  causing  summer-com- 
plaint and  other  diseases.  In  their  experience,  fat  and  apparently 
healthy  children  may  be  raised  on  condensed  milk  who,  however,*  will 
never  equal  in  strength  and  resistance  to  disease  those  who  were  raised 
on  woman's-  or  fresh  cow-milk. — Pharm.  Post,  Feb.  16,  p.  60. 
Ethylic  Alcohol  in  Coal-Tar. — At  the  fiftieth  meeting  of  Ger- 
man naturalists  and  physicians,  held  at  Munich,  O.  Witl  stated  that  a 
series  of  experiments  with  150,000  kilos  of  common  benzol  had  con- 
vinced him  of  the  uniform  presence  in  it  of  ethylic  alcohol,  the  average 
amount  being  *2  per  cent. — Ztschr.  cest.  Apoth.  Ver.,  April  10,  p.  166. 
Determination  of  Santonin  in  Levant  Wormseed. — DragendorfF 
recommends  to  digest  for  2  hours  15  or  20  grms.  of  the  wormseed 
with  15  or  20  cc.  of  a  10  per  cent,  soda-lye  and  200  cc.  of  water.  The 
liquid  is  filtered,  the  residue  washed  with  distilled  water,  the  filtrates 
united  and  concentrated  in  a  water-bath  to  about  30  or  40  cc.  After 
cooling,  the  liquid  is  neutralized  with  hydrochloric  acid,  immediately 
filtered  and  the  filter  washed  with  15  or  20  cc.  of  water.  The  pre- 
cipitate may  be  washed  with  an  8  per  cent,  soda  solution.  If  santonin 
crystals  are  formed  on  the  filter  these  are  collected,  and  afterwards 
united  with  the  remainder  of  the  santonin.    The  filtrate,  after  the
