follow  it  by  a  mixture  of  diluted  acetic  acid  and  water  in  the  same 
proportion  as  before,  until  the  percolate  measures  450  c.c. 
Dissolve  the  sugar  in  the  percolate  by  agitation  without  heat, 
strain  and  pass  a  sufficient  quantity  of  the  same  acid  mixture  as 
before  through  the  strainer  to  make  the  product  measure  1,000 
c.c.    Mix  thoroughly. 
SYRUPUS  ros^:. 
By  F.  W.  Haussmann. 
This  agreeable  mildly  astringent  syrup  is  deserving  of  more  fre- 
quent use. 
It  is  prepared  according  to  the  Pharmacopoeia  by  admixture  of 
fluid  extract  of  rose  and  simple  syrup,  which  process,  as  the  syrup 
is  intended  to  be  prepared  extemporaneously,  is  satisfactory  for 
ordinary  purposes. 
Syrup  of  rose  is  somewhat  cloudy  when  thus  prepared  and  shows 
a  deposit  on  standing,  the  usual  result  of  mixing  fluid  extracts  with 
syrup.  Should  the  syrup  be  required  to  be  kept  on  hand  for  a  time, 
the  following  formula  yields  a  clear  and  bright  syrup. 
SYRUPUS  ROS^. 
Fluid  extract  of  rose  125  c.c. 
Diluted  sulphuric  acid   .   10  -  " 
Sugar     750  grammes. 
Water,  a  sufficient  quantity  to  make  1  000  c.c. 
Mix  the  fluid  extract  of  rose  with  300  c.c.  of  water,  previously 
mixed  with  the  diluted  sulphuric  acid. 
Allow  the  mixture  to  stand  for  two  hours,  filter,  and  in  the  fil- 
trate dissolve  the  sugar  by  agitation  without  heat,  and  strain. 
Finally  add  a  sufficient  quantity  of  water  through  the  strainer  to 
make  the  syrup  measure  1,000  c.c. 
Mix  thoroughly. 
The  advantages  of  adding  diluted  sulphuric  acid  are  the  production 
of  a  brighter  colored  syrup,  an  agreeable  acidulous  taste  and  possibly 
an  increase  in  astringency. 
The  disadvantage,  however,  is  the  liability  of  the  inversion  of  the 
sugar  and  consequent  deposit  of  grape  sugar  on  prolonged  standing.
