until  the  mass  becomes  green,  adding  water,  if  necessary  to  impart 
a  pilular  consistence,  and  divide  into  five-grain  pills.  The  pills  are 
known  as  Blaud's  pills.  Each  pill  contains  about  one  grain  of  car- 
bonate of  iron. 
Pulvis  Sodce  TartaratcE  effervescens. — This  is  the  Seidlitz  powder, 
and  differs  from  the  formula  of  the  U.  S.  P.  only  in  the  use  of  38

parts;  Sodium  Bicarbonate  100  parts;  Tartaric  Acid  54  parts; 
Citric  Acid  36  parts.  The  final  product  should  weigh  about  200 
parts.  Dry  the  phosphate  until  it  has  lost  rather  more  than  half 
(60  per  cent.)  of  its  weight,  powder,  mix  with  the  other  ingredients, 
previously  powdered,  and  granulate  as  directed  above  for  efferves- 
cent magnesium  sulphate.

sodium  sulpnate,  in  crystals,  100  parts,  in  the  place  of  the  phosphate, 
and  drying  it  until  it  has  lost  about  56  per  cent,  of  its  weight.

set  aside  until  the  gelatin  is  quite  soft ;  add  the  glycerin ;  dissolve 
over  a  water-bath,  and  evaporate  until  the  mixture  weighs  1,560 
grains ;  pour  the  product  into  suppository  moulds  holding  30,  60  or 
120  grain-measures,  or  having  other  capacities  as  required.  Each 
suppository  contains  70  per  cent,  by  weight  of  glycerin.

remove  the  flask  from  the  source  of  heat,  add  the  citric  acid,  filter 
the  solution  through  a  small  paper  filter  into  10  fl.  ozs.  of  the 
syrup,  pass  the  remainder  of  the  water  through  the  filter  into  the 
syrup,  add  sufficient  syrup  to  make  one  pint  (20  fl.  oz.),  and  mix 
thoroughly.
