PHARMACEUTICAL  NOTICES.

Thus  prepared,  the  tincture  contained  fully  as  much  oil  as 
when  prepared  by  the  process  of  the  U.  S.  P.,  and  withstood  a 
much  greater  degree  of  cold.  At  the  temperature  of  40°  the 
officinal  tincture  was  rendered  quite  opaque,  while  this  retained 
its  transparency.  It  also  formed  transparent  mixtures  with  syr. 
squills  and  syr.  ipecac. 
Carb.  magnesia  was  afterward  substituted  as  an  agent  for  di- 
viding the  oil,  and  was  found  to  answer  the  purpose  perfectly.  The 
alcohol  used  was  of  sp.  gr.  *835. 
By  substituting  the  following  process  for  the  officinal  formula, 
pharmaceutists  would  obtain  a  preparation  which  would  be  much 
more  satisfactory  to  all  parties  interested : 
Macerate  the  opium  with  the  water  and  Oss.  alcohol  for  seven 
days  and  filter  through  paper.  To  this  add  the  honey  and  mix 
thoroughly.  Rub  the  camphor  with  a  little  alcohol  until  it  be- 
comes pasty,#then  add  the  powdered  pumice  stone,  and  triturate 
them  well  together,  adding  the  oil  and  acid.  Mix  thoroughly, 
and  add  the  honey  and  opium  mixture.  Then  filter,  and  when 
all  has  passed  through,  wash  the  filter  with  two  ounces  alcohol, 
and,  after  it  has  passed,  add  the  remaining  six  ounces  of  alcohol 
to  the  filtered  liquid.  When  carb.  magnesia  is  used,  the  acid 
should  be  dissolved  in  the  six  ounces  of  alcohol  which  is  added 
finally.  When  it  is  to  be  prepared  quickly,  the  equivalent  pro- 
portion of  tr.  opii  may  be  used  in  place  of  the  opium. 
Extemporaneous  dispensing  of  Ferri  Iodidi  in  Pills  and  Mixtures. 
The  greatly  increased  use  of  iodide  of  iron  by  medical  prac- 
titioners, renders  it  desirable  to  be  able  to  dispense  this  salt  when 
ordered  in  a  pure  state.
