In  the  foregoing  formula,  instead  of  using  two  pints  of  85  per 
ct.  alcohol  and  four  fluid- ounces  of  water,  as  directed  in  the  of- 
ficinal formula,  I  take  twenty-nine  and  a  half  fluid-ounces  of  alco- 
hol of  92  per  ct.  and  six  and  a  half  fluid-ounces  of  water.  These 
proportions  afford,  in  the  finished  product,  the  proper  alcoholic 
strength  required  by  the  U.  S.  P.,  with  almost  mathematical 
exactness. 
The  quantity  of  water  rendered  available  by  this  plan  of  ope- 
rating is  sufiicient  to  disintegrate  and  soften  the  soap,  and  render 
it  almost  immediately  soluble  in  the  alcohol. 
I  have  generally  been  in  the  habit  of  using  95  per  ct.  alcohol, 
as  it  admits  of  the  use  of  about  one  fluid-ounce  rtiore  water  than 
the  alcohol  fort.,  but  as  it  is  a  strength  of  alcohol  not  recognized 
as  an  officinal  standard,  I  have  in  the  above  formula  directed  the 
latter,  although  I  presume,  in  practice,  the  former  will  be  almost 
universally  employed. 
By  the  above  method  of  operating,  if  the  soap  is  in  proper  con- 
dition, a  gallon  of  soap  liniment  can  be  made  and  filtered  ready 
to  dispense  in  about  an  hour.  From  five  to  fifteen  minutes  is  all 
that  is  necessary  for  the  solution  of  the  soap,  if  it  is  properly 
Manipulated,  the  balance  of  the  time  being  consumed  in  the  fil- 
tration. 
This  process  the  most  conscientious  pharmacist  may  adopt  and 
feel  that  he  is  complying  with  the  spirit  if  not  the  strict  letter  of 
the  standard  authority.  A  single  trial  will  convince  any  one  of 
the  advantage  it  possesses  over  the  officinal  process.
