Any  attempt  to  do  this  with  the  solid  salt  as  furnished  to  the 
trade  is  impossible,  as  the  atmosphere  will  destroy  any  specimen, 
even  if  it  were  unaltered  when  the  containing  vial  is  first  opened. 
I  feel  the  more  free  to  direct  the  attention  of  pharmaceutists 
to  this  matter,  as  it  has  already  been  done  by  Dr.  D.  F.  Wright, 
of  Memphis,  Tenn.,  in  the  Am.  Jour,  of  Pharmacy  for  January, 
1854,  and  also  by  M.  Perrens,  of  France,  in  March,  1855.  The 
following  formula  is  submitted  as  the  result  of  experiments  with 
this  view  : 
R.  Iodinii,       ....       grs.  xl. 
Ferri  redacti., 
Acaciae  pulv.  aa., 
Sacchari  pulv., 
Glycerine,  . 
Althaeas  pulv., 
To  be  made  into  fifty  pills. 
Triturate  the  iodine  and  the  iron  thoroughly  together,  dry, 
until  they  are  reduced  to  a  fine  powder ;  then  add  the  glycerine, 
and  rub  till  the  fumes  of  iodine  cease  to  be  given  off,  and  the 
mixture  assumes  a  greenish  color. 
Then  add  the  powd.  acacia  and  sugar,  and  lastly  sufficient 
powd.  althaeae  to  bring  to  a  pilular  consistence. 
The  mass  should  be  very  stiff.  When  the  pills  are  formed  roll 
them  in  ferri  pulv.,  and  then  coat  them  with  tolu,  as  directed  by 
the  CJ.  S.  P. 
This  formula  is  not  offered  with  a  view  to  supersede  that  of 
the  U.  S.  P.,  but  as  one  which  will  do  very  well  when  iodide  of  iron 
is  prescribed,  combined  with  extracts,  &c. ;  or  when  the  simple 
pil.  ferri  iodidi  are  ordered,  and  sufficient  time  is  not  given  to 
prepare  them  by  the  officinal  formula.  When  prepared  in  this 
way  they  are  quite  permanent. 
But  efficient  as  may  be  the  formula  here  given,  it  may  be  ob- 
jected to  upon  the  ground  that  some  portion  of  the  iodine  may 
escape  combination,  as  we  have  not  the  same  means  of  knowing 
that  it  is  all  combined  that  we  have  when  prepared  by  the  offici- 
nal process.  Yet  to  be  controlled  in  the  size  of  pills,  and  unable 
to  combine  other  remedies  indicated  by  the  disease  is  so  annoy- 
ing, that  I  have  thought  it  best  to  recommend  a  syrup  containing
