forming  a  green  solution.    This,  upon  evaporation,  leaves  an  olive  col- 
ored salt  in  scales.    I  make  it  by  the  following  formula : 
R.    Ferri  hjpophosphitis,  3vj 
Acidi  Citrici,  3iv  ^ij 
Liq.  Ammon.  fort.  q.s.  ad  sat. 
Pulverize  the  citric  acid  and  saturate  by  addition  of  the  ammonia. 
Mix  the  hypophosphite  of  iron  with  this  in  a  flask  and  add  ammonia 
until  the  mixture,  which  is  of  a  yellow  color,  becomes  dark  olive,  or  un- 
til it  is  neutral  to  test  paper.  Pour  this  into  a  capsule  and  evapo- 
rate until  it  assumes  a  syrupy  consistence,  stirring  to  assist  desicca- 
tion. Then  set  aside  in  a  dry  place  until  it  solidifies.  When  quite 
bard  break  into  small  pieces  and  put  into  a  bottle.  As  thus  prepared, 
it  has  a  pleasant  slightly  acid  taste.  It  is  very  soluble  in  water  and 
will  be  found  an  eligible  preparation  for  dispensing  in  the  form  of 
syrup,  elixir,  or  pill. 
The  above  quantities  produce  one  ounce  and  a  half  of  the  soluble 
hypophosphite  of  iron,  and  the  preparation  therefore  contains  50 
per  cent,  of  the  common  hypophosphite. 
ON  SYRUPUS  ASSAFCETID^. 
By  John  M.  Maisch. 
Z  Some  years  ago  Mr.  Rich.  Peltz  proposed  a  syrup  of  Assafoetida 
containing  15  grains  of  the  gum  resin  in  each  fluid  ounce,  and  which 
was  intended  as  a  permanent  substitute  for  the  officinal  mistura  assa- 
foetidse,  which  in  the  course  of  a  few  days  usually  spoils.  During 
the  prevalence  of  whooping  cough,  a  few  years  ago,  when  assafoetida 
was  often  prescribed,  I  prepared  a  syrup,  which  was  used  by  several 
physicians  to  their  entire  satisfaction,  and  which  has  kept  well  up  to 
the  present  time.  Instead  of  the  boiling  water  used  by  Mr.  Peltz,  I 
have  employed  water  at  the  ordinary  temperature  and  added  some 
orange  flower  water,  which  covers  to  some  extent  the  odor  of  assa- 
foetida, without  masking  it  altogether. 
Two  drachms  of  selected  tears  of  assafoetida  are  triturated  with  a 
sufficient  quantity  of  water  until  three  fluid  ounces  of  emulsion  have 
been  obtained,  to  which  half  a  fluid  ounce  of  triple  orange  flower 
water  is  added,  and  afterwards  six  troy  ounces  of  sugar,  which  is  to 
be  dissolved  by  agitation  without  the  aid  of  heat.  It  is  important  to 
perfectly  emulsionize  the  assafoetida  with  the  small  amount  of  water,
