Am.  Jour.  Pharm. 
Sept.,  1884. 
tract  of  butternut  bark,  J  fluidounce;  fluid  extract  of  Alexandria  senna, 
2  fluidounces ;  flavor,  a  sufficient  quantity;  simple  syrup,  4  fluidounces ; 
deodorized  alcohol,  4  fluidounces;  citric  acid,  40  to  60  grains;  water,

Elixir  laxans  (Laxative  Elixir,  mild). — Calcined  magnesia,  120 
grains ;  acetic  acid,  a  sufficient  quantity ;  fluid  extract  of  Alexandria 
senna,  2  fluidounces ;  fluid  extract  of  coriander,  2  fluidracbms ;  deodor- 
ized alcohol,  1  fluidounces;  simple  syrup,  4  fluidounces;  citric  acid,  30 
to  60  grains ;  water,  sufficient  to  make  1  pint. 
Elixir  of  Rhubarb  and  Magnesia. — Rhubarb,  10  grains;  magnesia, 
5  grains  to  the  tablespoonful  dose. 
Calcined  magnesia,  1,280  grains;  acetic  acid,  a  sufficient  quantity; 
fluid  extract  of  rhubaib,  5  fluidounces  and  2f  fluidrachms;  deodorized 
alcohol,  2  pints;  simple  syrup,  2  pints;  flavor  to  suit  taste;  water  suf- 
ficient to  make  1  gallon.

according  to  taste. 
The  U.  S.  Pharmacopoeia  of  1880  has  the  following  modified  for- 
mula for  Liquid  Citrate  of  Magnesium,  using  carbonate  in  place  of 
calcined  magnesia  as  required  by  the  U.  S.  Pharmacopoeia  of  1860 : 
Carbonate  of  magnesia,  200  grains;  citric  acid,  400  grains;  syrup 
of  citric  acid,  1,200  grains;  bicarbonate  of  potassium,  30  grains;  water, 
a  sufficient  quantity  to  fill  a  bottle  of  about  16  fluidounces. 
To  replace  this  by  acetate  of  magnesium,  I  would  propose  the  fol- 
lowing formula: 
Solution  of  Acetate  of  Magnesium. — Carbonate  of  magnesium,  200 
grains;  acetate  acid,  sufficient  quantity  to  neutralize;  syrup  of  citric 
acid,  1,200  grains;  bicarbonate  of  potassium,  30  grains;  water  enough 
to  fill  a  bottle  of  about  16  fluidounces. 
Liguor  Magnesias  Citratis  (U.  S.  Pharmacopoeia,  1860). — Magnesia 
(calcined),  120  grains;  citric  acid,  450  grains;  syrup  of  citric  acid, 
2  fluid  ounces;  bicarbonate  of  potassa,  40  grains. 
To  replace  this  by  acetate  of  magnesium  the  following  formula 
might  be  used : 
Liquor  Magnesii  Acetatis,  or  Solution  of  Acetate  of  Magnesium 
(Magnesia). — Calcined  magnesia,  126  grains;  acetic  acid,  sufficient 
quantity  to  saturate ;  syrup  of  citric  acid,  2  fluidounces ;  bicarbonate  of 
potassa,  40  grains. 
Detroit,  Michigan.
