ON  COMPOUND  SYRUP  OF  HYPOPHOSPHITES.  227 
cloudiness,  especially  if  it  is  much  alcoholic.  The  following  is 
the  revised  formula  : 
Take  of  Hypophosphite  of  lime  256  grs. 
Hypophosphite  of  soda  192  grs. 
Hypophosphite  of  potassa  128  grs. 
Hypophosphite  of  iron*  (recently  pre- 
cipitated) 96  grs. 
Hypo-phosphorous  acid,  solution,  q.  s.  or  240  grs. 
Syrup  of  vanilla  half  a  pint. 
Boiling  water  a  sufficient  quantity. 
Put  the  lime,  soda,  and  potassa  salts  in  a  large  mortar,  add 
the  hypophosphorous  acid  and  mix,  then  the  moist  hypophos- 
phite of  iron,  and  triturate  till  a  uniform  smooth  mixture  results. 
Four  ounces  of  boiling  water  is  now  poured  in,  and  after  tri- 
turation, the  clear  liquid  is  decanted  from  the  undissolved  portion 
to  a  filter,  and  more  water  added  till  it  is  dissolved  and  the  filtered 
liquid  amounts  to  eight  fluid  ounces.  To  this  solution,  while 
still  warm,  add  the  syrup  of  vanilla  previously  acidulated  with 
a  few  drops  of  solution  of  hypophosphorous  acid,  and  mix. 
As  stated  before,  each  teaspoonful  contains  2  grs.  of  the  lime 
salt,  1.J  grs.  of  the  soda  salt,  1  gr.  of  the  potash  salt,  and  |  gr. 
of  the  iron  salt,  with  a  little  free  hypophosphorous  acid.  The 
small  proportion  of  sugar  in  this  preparation  almost  deprives  it 
of  the  right  to  the  name  of  syrup,  but  it  is  sufficient  for  its  pre- 
servation and  renders  it  agreeable. 
Since  the  publication  of  my  former  article  this  syrup  has  been 
used  by  several  physicians  in  cases  of  a  pulmonary  character, 
with  tendency  to  hemorrhage,  loss  of  appetite  and  cough,  with 
very  decided  benefit.  In  one  instance  the  patient  was  much 
emaciated,  with  cough  and  loss  of  appetite,  but  recovered  his 
flesh  and  strength  under  its  use. 
*  This  quantity,  ninety-sis  grains,  of  hypophosphite  of  iron  is  obtained, 
When  128  grs.  of  hypophosphite  of  soda,  dissolved  in  2  fluid  ounces  of 
water,  is  decomposed  with  a  slight  excess  of  solution  of  persulphate  of  iron, 
and  the  whole  precipitate  well  washed  on  a  filter  with  water.
