SOLUTION  OF  IODOFORM  AND  IODOFORM  ED  LINT. 
By  G.  A.  Keyworth,  F.C.S  ,  Hastings. 
Read  at  the  British  Pharmaceutical  Conference. 
When  iodine  tincture  is  shaken  with  a  fragment  of  fused  potash  so 
as  to  remove  the  color,  the  essential  step  in  the  preparation  of  iodoform, 
the  characteristic  odor  of  that  substance  appears.  ■  In  this  simple  form 
the  fluid  possesses  great  energy  as  a  therapeutic  agent,  more  especially 
in  the  healing  of  indolent  sores,  for  which  purpose  iodoform  is  so  highly 
valued  by  some  medical  practitioners.  Iodine  ointment  of  various 
strengths,  alone  or  combined  with  a  small  quantity  of  carbolic  acid,  has 
long  been  known  to  have  great  power  in  producing  cicatrization  and 
granulation  with  obstinate  ulcers,  sores  and  wounds.  The  odor  of 
iodoform,  which  is  to  many  persons  very  repulsive,  may  be  readily  con- 
cealed by  the  addition  of  eau  de  cologne  or  lavender  water. 
The  alcoholic  solution  above  described,  when  so  treated,  furnishes 
an  elegant  substitute  for  iodine  tincture,  with  its  dark  color,  strong 
<chlorine-like  odor,  and  staining  property.  Lint  soaked  in  this  colorless 
.perfumed  liquid,  and  allowed  to  dry,  is  a  singularly  useful  application 
for  various  sores,  promoting  the  healing  process  with  much  energy. 
Equal  parts  of  this  fluid  and  glycerin  form  a  very  useful  combination 
for  many  purposes. — Phar.  your,  and  Trans.  [Lond.],  Sept.  14, 
THE  EXTRACTION  OF  EMETIA  FROM  THE  DEPOSIT 
IN  VINUM  IPECACUANHA. 
By  George  Brownen,  F.C.S. 
Read  at  the  British  Pharmaceutical  Conference. 
It  is  not  my  intention  to  direct  the  attention  of  this  Conference  to 
the  chemistry  of  ipecacuanha  ;  that  has  been  done  by  our  secretary, 
Professor  Attfield  and  others.  At  the  Birmingham  meeting  in  1865, 
a  paper  was  read  by  Mr.  Johnson,  in  which  some  of  the  causes  at 
least  of  the  instability  of  ipecac  wine  were  noticed  and  suggestions 
made  ;  yet  in  the  revision  of  the  Pharmacopoeia  after  that  date  these 
suggestions  were  either  set  aside  or  forgotten  and  the  same  objection- 
able and  unsatisfactory  formula  is  preserved  by  authority  in  the  Phar- 
macopoeia of  1867. 
I  do  not  intend  to  dilate  on  the  turbid  solution  and  unsightly  deposit 
which  continuously  forms  as  long  perhaps  as  there  is  anything  in  the
