Grate  the  soap  on  a  common  grater,  and,  having  mixed  the  water 
with  \  pint  of  alcohol,  pour  this  on  the  soap  ;  with  occasional  agita- 
tion it  will  dissolve  in  a  short  time.  Dissolve  the  camphor  and  oil  of 
rosemary  in  remainder  of  alcohol.  Add  this  to  the  solution  of  soap, 
let  stand  some  time  and  filter.  The  result  is  a  preparation  which  will 
not  precipitate.  It  is  not  as  strongly  alcoholic  as  the  officinal,  but  it 
contains  as  much  alcohol  as  is  compatible  (?  Ed.)  with  it  as  a  pre- 
paration. 
Aromatic  Sulphuric  Acid. — The  writer  recommends  S.  Whittier's 
formula  ("  Am.  Jour.  Pharm.,"  1874,  p.  509). 
Syrup  of  Tolu. — In  filtering  the  mixture  of  tincture  of  tolu,  magne- 
sium carbonate  and  water,  nothing  but  a  flavored  water  is  obtained,  as 
the  resin  upon  which  the  medicinal  virtues  depend  is  left  in  the  filter. 
It  is,  therefore,  a  sacrifice  of  the  medicinal  virtues  of  tolu  for  the  sake 
of  getting  an  elegant  preparation.  I  have  tried  to  combine  the  medi- 
cinal as  well  as  pharmaceutical  properties,  and  believe  to  have  suc- 
ceeded, by  the  following  formula  :  Take  the  required  amount  of 
tincture  of  tolu,  magnesium  carbonate  and  a  small  quantity  of  sugar, 
rub  them  together  and,  instead  of  adding  water,  add  simple  syrup 
(hot),  sufficient  to  make  the  desired  quantity  of  syrup.  After  standing 
a  short  time,  strain  slowly  through  flannel. 
Syrup  of  Ginger  may  also  be  made  advantageously  by  this  process. 
,Syrupus  Aurantii  Cortic:s. — As  this  preparation  is  mostly  used  as  a 
pleasant  vehicle  to  disagreeable  medicines,  and  especially  those  derived 
from  iron,  I  submit  a  formula,  which  has  the  decided  advantage  in 
affording  a  preparation  which  will  not  be  discolored  by  an  iron  pre- 
paration. One  precaution  is  necessary,  to  use  a  fresh  oil  ;  the  best 
plan  is  to  make  it  up  into  spirit  of  orange  at  once,  one  part  of  oil  to 
fifteen  of  strong  alcohol. 
Take  spirit  of  orange,  carbonate  magnesium,  sugar  and  water,  and 
proceed  in  the  same  manner  as  for  preparing  the  syrup  of  tolu  of  the 
"  U.  S.  Pharmacopoeia,"  using  the  same  proportions. 
Aromatic  Syrup  of  Rhubarb,  as  prepared  after  the  officinal  process,  is 
generally  an  unsightly  preparation. 
I  have  found  the  officinal  process,  with  some  slight  modification, 
renders  a  satisfactory  preparation.  After  exhausting  the  rhubarb,  &c.y 
with  the  alcoholic  menstruum,  rub  it  up  in  a  mortar  with  a  small 
quantity  of   carbonate  of   magnesium  and  some  sand.    Pack  this
