PHARMACEUTICAL  NOTES. 
capacity  of  at  least  a  pint,  add  the  card  teeth  in  small  portions 
at  a  time  as  the  action  progresses,  having  previously  placed  the 
flask  in  a  sand  bath. 
Insert  into  the  mouth  of  the  flask  a  tuft  of  card  teeth  moistened 
with  water,  to  arrest  and  prevent  the  escape  of  a  portion  of  the 
bromine  should  the  action  become  violent. 
When  the  action  has  ceased,  heat  the  solution  of  bromide  of 
iron  containing  the  remaining  or  undissolved  portion  of  the  card 
teeth  to  the  boiling  point,  and  filter  through  paper  into  a  bottle 
containing  the  sugar,  marked  to  the  measure  of  a  pint. 
Wash  the  undissolved  card  teeth  with  a  small  portion  of  water, 
and  add  the  washing  to  the  contents  of  the  bottle  through  the 
filter,  followed  with  sufficient  water  to  make  a  pint  of  syrup. 
This  syrup  contains  nearly  a  drachm  of  the  salt  to  each  fluid- 
ounce. 
Syrup  of  Hypophosphite  of  Iron, 
Take  of  Hypophosphite  of  Lime,  256  grains  ; 
Protosulphate  of  Iron,  493  grains  ; 
Sugar,  10  troy-ounces ; 
Hypophosphorous  Acid,  a  sufficient  quantity  ; 
Water,  a  sufficient  quantity. 
Dissolve  the  hypophosphite  of  lime  in  four  fluid-ounces  of  boil- 
ing water,  and  acidulate  the  solution  with  hypophosphorous  acid. 
Dissolve  the  protosulphate  of  iron  in  four  fluid-ounces  of  boil- 
ing water,  mix  it  with  the  lime  solution,  and  set  the  mixture 
aside  for  two  or  three  hours.  When  the  reaction  has  ceased  and 
the  sulphate  of  lime  formed  has  subsided,  decant  the  clear  iron 
solution  and  pour  it  into  a  bottle  containing  the  sugar,  marked 
to  the  measure  of  a  pint,  and  add  water  sufficient  to  make  a  pint 
of  syrup.  When  the  sugar  is  dissolved,  after  occasional  agitation 
transfer  the  syrup  to  small  vials  and  cork  tightly. 
Each  fluid-ounce  of  this  syrup  contains  sixteen  grains  of  ferrous 
hypophosphite.
