104  Syrups  of  Squills,  Seneka  and  Ipecac.  {^u^'^Cim^' 
Moisten  the  seneka  with  two  fluidounces  of  the  diluted  alcohol, 
then  transfer  it  to  a  conical  percolator  and  gradually  pour  upon  it 
the  remainder  of  the  diluted  alcohol.  When  the  tincture  has  ceased 
to  pass  evaporate  it  by  means  of  a  water-bath,  at  a  temperature  not 
exceeding  160°,  to  half  a  pint.  Rub  it  with  the  carbonate  of  mag- 
nesia in  a  mortar  till  thoroughly  mixed,  filter  and  add  sufficient  warm 
water  through  the  filter  to  make  the  filtrate  measure  half  a  pint,  and, 
having  added  the  sugar,  mix  well  together,  and  note  accurately  the 
measure  of  the  mixture  while  cold  ;  then  dissolve  the  sugar  with  the 
aid  of  a  gentle  heat,  strain  the  solution  while  hot,  add  sufficient 
warm  water  through  the  strainer  to  bring  the  syrup,  when  cold,  to  the 
previously  noted  measurement,  and  mix  them  thoroughly. 
Syrupus:  Ipecacuanhce. 
(Modified  from  former  editions  of  the  U.  S.  P.) 
Take  of  Ipecacuanha,  in  fine  powder,  two  troyounces. 
Diluted  Alcohol, 
Water,  each  a  sufficient  quantity. 
Sugar  (refined)  in  coarse  powder,       twenty-nine  troyounces. 
Carbonate  of  Magnesia,  forty-five  grains. 
Moisten  the  ipecacuanha  with  one  fluidounce  of  the  diluted  alcohol, 
let  it  stand  for  twenty-four  hours.  Then  transfer  it  to  a  conical  per- 
colator and  gradually  pour  upon  it  diluted  alcohol  until  one  pint  of 
tincture  has  passed.  Evaporate  this  by  means  of  a  water-bath  to  six 
fluidounces,  add  ten  fluidounces  of  warm  water,  and,  having  rubbed  it 
thoroughly  with  the  carbonate  of  magnesia  in  a  mortar,  filter,  and 
add  sufficient  warm  water  through  the  filter  to  make  the  filtrate 
measure  one  pint  ;  then  add  the  sugar,  and  dissolve  it  with  the  aid  of 
a  gentle  heat,  and,  having  strained  the  hot  syrup,  add  sufficient  warm 
water,  through  the  strainer,  to  make  it  measure  two  pints  when  cold. 
It  will  be  seen  that  the  chief  point  of  difference  between  the  two 
first  formula  above  given  and  the  U.  S.  P.  requirements  is  the  filtra- 
tion of  the  evaporated  tinctures  through  carbonate  of  magnesia  instead 
of  paper  only;  but  I  would  call  the  attention  of  the  authors  and 
revisers  of  both  the  Pharmacopoeia  and  Dispensatory  to  the  lack  of 
explicit  directions  in  many  of  the  formulae  for  syrups,  from  which  I, 
with  many  others,  have  suff'ered  loss  and  trouble.  The  difficulty  is 
mainly  in  the  want  of  full  and  accurate  directions  in  regard  to  the 
various  measurements.    For  example,  the  closing  directions  in  the
