Mix  the  hictic  acid  with  2  fluidounces  of  water,  and  saturate  it 
with  the  magma.  Put  the  liquid  upon  a  filter,  and  add  the  rest  of 
tlie  water  until  8  fluidounces  of  filtrate  are  obtained.  Pour  this  upon 
the  sugar,  contained  in  a  bottle  ;  shake  occasionally  until  solution  is 
effected,  and  strain.  No  heat  ought  to  be  applied,  else  the  syrup 
assumes  a  milky  appearance. 
The  syrup  thus  prepared  contains  between  2  and  3  grains  of  dry 
phosphate  of  lime  in  each  fl^,  besides  the  lactic  acid.

ELIXIR  CINCHONA  ET  FERRI  CHLORIDI. 
By  W.  W.  Seay. 
I  send  you  my  formuhi  for  this  preparation,  which  I  have  used  for 
years,  and  found  it  very  satisfactory  in  its  results.  It  requires  very 
great  care  in  the  details,  but,  properly  prepared,  will  keep  without 
blackening  for  an  indefinite  length  of  time.  I  have  a  sample  on  hand 
which  has  kept  bright  and  clear  for  nearly  six  years.  Each  pint  con- 
tains one  troyounce  of  red  bark,  a  little  .over  one  troyounce  of  aro- 
matics,  and  the  equivalent  of  one  fluid-drachm  of  tinct.  ferri  chloridi 
(U.  S.  P.)    The  iron  used  is  of  course  protochloride.
