received  the  attention  it  merits,  and  with  a  view  of  bringing  it 
more  to  the  notice  of  the  profession,  I  give  the  formula. 
Take  of  Iodide  of  Potassium  eight  troyounces. 
Alcohol,  30°  Baume,  two  pints. 
Mix  the  above  and  form  a  perfect  solution. 
Animal  soap  finely  shaved  fourteen  troyounces. 
Alcohol,  30°  Baume',  two  pints. 
Dissolve  the  soap  in  the  alcohol  in  a  flask  over  a  sand  bath ; 
when  dissolved  mix  the  two  solutions  and  add 
Oil  of  garden  lavender  two  drachms. 
This  is  usually  dispensed  in  one  or  two  ounce  wide  mouth  vials, 
which  should  be  filled  while  the  opodeldoc  is  warm  and  in  a  fluid 
condition ;  when  cold  it  forms  a  translucent  mass,  melting  at  the 
temperature  of  the  body,  and  as  an  external  application,  posses- 
sing many  advantages  over  the  ointment  of  iodide  of  potassium. 
ON  A  NEW  SUPPOSITORY  MOULD. 
Messrs.  Bullock  &  Crenshaw,  of,  Philadelphia,  have  gotten  up 
a  new  and  convenient  mould  for  making  Suppositories.  The  cut 
shows  the  form  of  the  mould,  which  is  constructed  of  brass.  The 
instrument  opens  on  a  hinge  at  one  end  ;  a  pin  and  hole  at  the 
opposite  end  secures  proper  adjustment  of  the  two  surfaces, 
which  are  accurately  ground  to  each  other,  and  form  six  perfectly 
smooth  matrices.  A  sliding  ring  on  the  handles,  which  are  set 
at  a  slight  angle  to  each  other,  forms  a  sufficient  clamp  to  retain 
the  melted  material. 
In  using  the  mould,  they  heat  the  material  only  to  the  point 
of  liquefaction,  and  pour  it  into  the  matrices,  (which  should  be  pre- 
viously rubbed  with  a  little  olive  oil  on  cotton  or  wash  leather) ;  the 
mould  is  then  placed  in  cold  water  until  the  material  has  solidi- 
fied. To  remove  the  suppositories,  plunge  the  mould  for  an  in- 
stant into  water  warmed  to  about  100°  F.,  then  open  it,  and,  by
