PHARMACEUTICAL  GLEANINGS. 
Make  a  mucilage  with  the  tragacanth  and  water,  squeeze  it 
through  a  linen  cloth  as  in  making  lozenges,  mix  it  with  the 
sugar  of  milk  to  form  a  paste,  spread  this  on  plates,  dry  it  in  a 
stove  and  pulverize  it.  The  pills  are  coated  by  moistening  their 
surface  with  water  and  immediately  rolling  them  in  the  powder. 
The  moisture  fixes  a  portion  of  the  powder  on  their  surface,  and 
forms  a  coating. 
Ioduretted  Oil. — Some  time  since,  M.  Deschamps  proposed  an 
ioduretted  oil,  as  a  substitute  for  cod  liver  oil,  which  was  made 
by  dissolving  iodine  in  almond  oil,  and  passing  steam  through 
the  solution  until  it  became  decolorized.  M.  Berths',  pharmacien 
of  Paris,  suggests  that  when  so  made  the  oil  acquires  a  disagree- 
able rancid  taste,  and  is  liable  to  become  black  by  standing  ;  and 
proposes  the  following  as  a  substitute.  Triturate  seventy-five 
grains  of  iodine,  with  thirty-two  ounces  of  the  oil  of  almonds,  heat 
the  mixture  in  a  water  bath  until  it  becomes  free  from  color,  and 
does  not  affect  damp  starch  paper.  It  is  not  acid,  but  becomes 
so  by  contact  with  moisture.  M.  Berths  considers  it  superior 
to  all  other  ioduretted  oils  known,  on  account  of  its  less  dis- 
agreeable taste  and  easy  preparation.  It  does  not  contain  all 
the  iodine  employed  in  its  preparation.  It  is  considered  prefer-^ 
able  to  operate  in  open  vessels,  as  the  oil  made  in  close  vessels 
becomes  dark  by  keeping. 
The  dose  is  about  the  same  as  that  of  cod  liver  oil.  M.  Berths 
has  also  prepared  an  iodophosphuretted  oil,  and  M.  Renault  an 
ioduretted  albumen,  but  doubts  have  been  expressed  in  regard 
to  their  usefulness  as  medicinal  agents.  For  further  particulars 
relative  to  all  these  compounds,  see  the  "  Dublin  Quarterly 
Journal  of  Medicine,"  and  "  Bulletin  Ge'ne'ral  de  Therapeutique." 
Means  of  removing  the  rancid  odor  of  Fats. — Dr.  Griseler  has 
accidentally  made  the  observation,  that  an  addition  of  nitric  ether 
to  rancid  oil  entirely  destroys  the  disagreeable  smell,  and  that 
when  the  oil  is  heated  to  separate  the  alcohol,  it  becomes  clear 
and  bright,  even  when  it  was  before  turbid.  Dr.  Griseler  says, 
that  a  few  drops  of  this  liquid  will  prevent  sweet  fixed  oils  from 
becoming  rancid.
