percolation  slowly,  using  first  the  balance  of  the  menstruum  and  then 
water  till  600  c.c.  of  percolate  is  obtained.  Dissolve  the  sugar  in 
this  by  heat  of  water-bath,  if  necessary,  strain,  and  add  sufficient 
water  to  obtain  1000  c.c.  of  product. 
Syrupus  Rubi  U.S. P. — This  drug  is  easily  extracted  by  glycerin, 
and  as  a  substitute  for  the  present  unsatisfactory  formula  the  follow- 
ing is  submitted : 
Rubus,  in  No.  20  powder   250  Gms. 
Glycerin   125  c.c. 
Sugar   800  Gms. 
Water,  a  sufficient  quantity. 
Mix  the  glycerin  with  375  c.c.  of  water  and  percolate  the  drug 
with  this  menstruum,  and  then  continue  with  water  until  600  c.c. 
of  percolate  is  obtained.  Dissolve  the  sugar  in  this  by  warming. 
Strain  when  cold  and  add  sufficient  water  to  obtain  1000  c.c.  of 
product. 
As  an  alternative  formula: 
Fluidglycerate  of  rubus   250  c.c. 
Syrup    750  c.c.

Syrupus  Sarsaparilla:  Compositus  U.S. P. — Any  one  who  has 
followed  the  official  instructions  for  the  preparation  of  this  syrup 
must  have  noted  the  decided  precipitate  produced  on  diluting  the 
fluidextracts  with  water.  A  pharmacist  likewise  is  impressed  with 
the  impropriety  of  adding  the  oils  to  the  fluidextracts  before  dilution, 
and  it  is  self-evident  to  any  one  examining  the  filter  that  a  good 
proportion  of  the  flavoring  is  retained  by  the  precipitate. 
Our  experiments  had  demonstrated  that  glycerol-water  men- 
struum would  satisfactorily  extract  both  sarsaparilla  6  and  licorice 
root,  and  while  senna  by  itself  could  not  be  percolated  with  this 
menstruum,  when  mixed  with  the  other  ingredients  in  the  propor- 
tion used  in  this  syrup  there  was  no  difficulty  in  percolation.  Tht 
sample  submitted  is  made  by  the  following  formula : 
6  Fluidglycerate  of  sarsaparilla  and  fluidextract  of  sarsaparilla  were  pre- 
pared from  the  same  lot  of  drug,  at  the  same  time,  and  have  been  kept  under 
the  same  conditions.  The  former  shows  little  or  no  precipitation,  while  the 
latter  exhibits  a  decided  deposit,  and  the  decanted  fluidextract  is  not  equal 
to  the  fluidglycerate  in  the  peculiar  aroma  and  acridity  of  the  drug.
