346  Tinatura  lodi.  {^'"ju'Jy^m""'' 
"  With  all  that  should  accompany  old  age  as  honor,  love,  obedience, 
troops  of  friends,'^  with  a  well  assured  religious  faith  and  hope,  he 
awaited  the  closing  hour  of  a  life  prolonged  beyond  the  common  lot 
of  man. 
He  deceased  on  the  29th  day  of  March,  1883,  in  the  91st  year  of 
his  age,  and  was  interred,  on  the  1st  of  April,  in  Friends'  Burying 
Ground,  at  Germantown.  C.  B. 
Pulvis  Ipecacuanhae  et  Opii. — The  change  made  in  the  pre- 
paration of  this  powder  induces  me  to  offer  a  formula  which  will  yield 
even  better  results  than  that  given  in  our  official  Codex.  The  perfect 
division  of  the  opium  and  ipecacuanha  is,  of  course,  the  prime  con- 
sideration in  this  preparation,  and  the  following  process  secures  this 
most  perfectly : 
Take  of  extract  of  opium,  dry  enough  to  powder,  one  part,  pow- 
dered ipecacuanha  two  parts,  sugar  of  milk  seventeen  parts;  dissolve 
the  opium  extract  in  a  sufficient  quantity  of  water  and  alcohol  in  pro- 
portion of  three  of  the  former  to  one  of  the  latter  to  make  a  smooth 
paste  with  the  ipecacuanha  and  sugar  of  milk.  When  they  are  well 
incorporated  put  the  mass  aside  in  a  warm  place  to  dry,  after  this 
has  been  effected  rub  the  whole  to  an  impalpable  powder  and  pass 
through  the  finest  bolting  cloth.  It  will  be  seen  that  this  process 
secures  all  the  activity  of  the  opium  and  ipecacuanha  in  a  most  per- 
fectly divided  condition. — T.  S.  Wiegand. 
Tinctura  lodi. — Having  noticed  the  recent  article^  in  regard  to 
the  preparation  of  tincture  of  iodine,  I  was  led  to  adopt  a  method  by 
which  tincture  of  iodine  of  officinal  strength  can  be  easily  as  well  as 
quickly  prepared  by  percolation,  as  follows : 
The  Iodine  is  to  be  rubbed  in  ^  mortar  to  a  moderately  coarse 
powder  (a  fine  powder  retards  the  process),  and  j)acked  tightly  in  a 
long,  narrow  percolator  (a  glass  syringe  capable  of  holding  two  fluid- 
ounces  will  answer),  the  lower  orifice  of  percolator  being  previously 
stopped  with  a  plug  of  absorbent  cotton;  then  the  alcohol  is  carefully 
poured  on  the  iodine  and  allowed  to  percolate  slowly. 
By  this  process,  a  pint  of  tincture  can  be  prepared  in  thirty  minutes^ 
and  for  neatness  and  despatch  it  is  to  be  preferred  to  any  other  way  I 
know  of.— W.  W.  Jost,  Ph.G.
