PHARMACEUTICAL  GLEANINGS. 
Take  of  True  oil  of  cloves, 
English  oil  of  lavander,  of  each         a  drachm. 
Oil  of  bergamot,  five  drachms, 
Strongest  solution  of  ammonia,  (sp.  gr.  .880)  one  pint, 
Mix  these  together.    The  bottles  are  then  to  be  half  filled  with 
rough  carbonate  of  ammonia,  and  filled  up  with  the  carbonate  in 
fine  powder.    The  salt  is  then  saturated  with  the  above  solution, 
and  corked  closely. 
Oil  of  JProtiodide  of  Iron. — M.  Grille  of  Paris  has  suggested 
that  oil  of  almonds  may  be  impregnated,  to  a  certain  extent,  with 
protiodide  of  iron,  provided  the  iodine,  iron  filings  and  the  oil 
are  mixed  together,  and  shaken  till  the  odor  of  iodine  disappears, 
which  requires  several  days. 
The  following  is  the  formula  suggested : 
Take  of  pure  iodine,  in  powder,  34  grains, 
Iron  filings,  230  grains, 
Oil  of  almonds,  25 ounces,  (Troy.) 
These  ingredients  are  mixed  together,  and  agitated  occasion- 
ally for  several  days.  The  oil  of  protiodide  of  iron,  when  com- 
plete, has  a  slight  amber  color,  no  odor  and  almost  without  taste. 
It  preserves  its  physical  and  medicinal  properties  for  some  time 
without  appreciable  alteration,  and  should  be  kept  in  glass  stop- 
pered bottles. 
In  the  Annals  of  Pharmacy,  from  which  we  extract  this  no- 
tice, it  is  not  stated  whether  M.  Gille  proved  the  presence  of 
iodide  of  iron  in  the  oil.  It  is  probable  that  some  reaction 
occurs  between  the  oil  and  iodine,  prior  to  or  coincident  with 
its  action  on  the  iron. 
Nitro-tannate  of  Mercury. — An  eminent  surgeon  of  Bordeaux, 
France,  recommends  an  ointment  made  of  an  ounce  of  lard, 
seventy-six  grains  of  tannin,  and  twelve  drops  of  acid  nitrate  of 
mercury,  as  an  application  in  certain  forms  of  syphilitic  ulcera- 
tions. . 
Remedy  for  tooth-ache. — Dr.  Whipple,  (Amer.  Journal  of 
Dental  Science^  recommends  oil  of  turpentine  as  a  remedy  for 
tooth-ache,  applied  on  a  pellet  of  cotton,  and  covered  with  dry 
cotton.  It  is  particularly  applicable  in  cases  where  the  pain 
results  from  inflammation  of  the  nerve,  or  from  irritation  caused 
by  wounding  the  pulp.
