COMPOUND  SULPHUR  OINTMENT. 
first  white,  but  soon  becomes  of  a  greenish-gray  color,  preserving 
this  shade.  Allow  this  precipitate  to  collect  during  twenty-four 
hours  ;  decant.  Afterwards,  take  a  solution  of  sugar  in  the 
following  proportions  ;  white  sugar,  two  and  a  half  ounces  ;  dis- 
tilled water,  ten  ounces  ;  dissolve  with  ebullition,  and  filter.  Add 
the  precipitate  to  this  saccharine  fluid  when  cold ;  set  it  aside  to 
rest ;  decant.  Repeat  this  process  once  more,  in  order  to  re- 
move the  sulphate  of  soda  resulting  from  the  double  decomposi- 
tion. This  washing  ought  to  be  accomplished  as  quickly  as 
possible  to  prevent  the  unnecessary  solution  of  the  ferruginous 
precipitate.  Subsequently,  agitate  this  precipitate  from  time  to 
time  in  a  fresh  portion  of  saccharine  solution  (water,  ten  ounces  ; 
sugar,  two  and  a  half  ounces).  It  will  dissolve  in  the  course  of 
some  days.  Lastly,  take  of  white  sugar  thirty-eight  and  a  half 
ounces ;  distilled  water,  nineteen  ounces ;  add  the  saccharine 
ferruginous  solution,  and  boil  to  specific  gravity  1.262,  at  the 
temperature  of  ebullition ;  flavor  with  tincture  of  lemon  or 
orange.  The  product  will  be  sixty-four  ounces  of  almost  color- 
less and  perfectly  clear  syrup  of  protocarbonate  of  iron,  con- 
taining 9.90  per  cent,  of  oxide  of  iron. — Dublin  Hospital  Cfaz.,

FORMULA  FOR  COMPOUND  SULPHUR  OINTMENT. 
The  following  is  the  formula  for  the  compound  sulphur  oint- 
ment successfully  employed  by  Messrs.  Startin  and  McWhinnie, 
at  the  Hospital  for  Diseases  of  the  Skin,  against  scabies,  favus, 
and  true  ringworm,  diseases  which  depend  upon  parasites  which 
it  is  necessary  to  kill. 
R. — Of  sublimed  sulphur  half  a  pound,  of  the  ammonia-chlo- 
ride of  mercury  half  an  ounce,  and  of  the  sulphuret  of  mercury 
half  an  ounce  ;  to  these,  well  rubbed  together,  add  four  ounces 
of  olive  oil,  sixteen  ounces  of  fresh  lard,  and  twenty  minims  of 
creasote.  It  will  be  seen  that  we  have  here  in  combination  three 
different  drugs,  each  possessing  great  efficiency  in  the  destruction* 
of  insect  and  fungus  life.  The  object  in  view,  that  of  obtaining 
a  vigorous  compound,  which,  at  the  same  time,  shall  not  be  irri- 
tating to  the  skin,  is,  we  believe,  exceedingly  well  attained. —
