together,  to  dissolve  the  biniodide  in  the  oil.  Solution  is  readily  effected  at 
the  ordinary  temperature  of  the  atmosphere  to  the  extent  of  half  a  grain  to 
the  fluid  ounce,  by  rubbing  down  the  biniodide  in  a  small  portion  of  the  oil, 
mixing  it  with  the  remainder  in  a  bottle,  and  shaking  for  a  few  moments;  at 
the  temperature  of  50°  C.  two  grains  are  permanently  dissolved  by  one  fluid 
ounce  of  oil. 
T  also  find  that  biniodide  of  mercury  dissolves  with  the  same  facility  in  al- 
mond, olive,  and  castor  oils,  also  in  chloroform,  pyroxilic  spirit,  and  melted 
lard  and  spermaceti  cerate.  J.  B.  Barnes.

Unguentum  Pyroligni  Juniperi. — Mr.  Erasmus  Wilson  has  furnished  us 
with  the  formula  for  this  preparation,  which  he  has  used  with  success  in 
some  cutaneous  disorders :

The  pyroligneous  oil  of  juniper,  or  juniper  tar,  is  obtained  by  the  destruc- 
tive distillation  of  juniper  wood.  It  is  called  in  France  HuiledeCade.  We 
believe  it  is  not  prepared  in  this  country,  but  may  be  obtained  from  Dr.  M. 
Meidenbach,  Aix-la-  Chapelle. — Ibid.

A  New  Mode  of  Mending  an  old  Sieve.  To  the  Editor  of  the  Pharma- 
ceutical Journal. — Sir  :  I  have  been  employing  myself  this  evening,  since 
the  shop  has  been  closed  (we  all  in  this  town  close  at  eight  o'clock),  in  doctor- 
ing an  old  sieve,  and  as  the  result  is  satisfactory  to  myself  I  communicate  the 
same  to  you.  The  sieve  is  a  wire  sieve,  and  had  been  laid  by  for  a  consid- 
erable time  as  useless  on  account  of  the  many  holes  and  fractures  in  the  tex- 
ture of  the  wire,  besides  which  the  meshes  were  very  much  clogged.  I  first 
had  the  sieve  well  washed  with  soda  and  water,  then  when  thoroughly  dry 
passed  the  sieve  slowly  over  a  gas  flame,  which  soon  carbonized  what  re- 
mained in  the  meshes  and  allowed  it  to  be  removed  with  a  dusting-brush.  I 
then  filled  the  torn  and  broken  parts  of  the  sieve  with  gutta  percha,  by  cut- 
ting a  bit  from  a  sheet  of  the  article  about  the  size  of  a  stick  of  lunar  caustic, 
just  melting  the  end  in  the  gas  flame  and  rubbing  it  over  the  broken  part  of 
the  sieve  as  soon  as  it  is  applied,  applying  a  little  friction  over  it  with  my
