DOES  NICOTINA  EXIST  IN  GREEN  TOBACCO,  OR,   IS  IT  A 
RESULT  OF  FERMENTATION  IN  THE  CURING  PROCESS  ? 
Br  "William  Procter,  Jr. 
At  a  meeting  of  the  American  Pharmaceutical  Association, 
held  in  Philadelphia,  Sept.,  1857,  the  following  question  was 
suggested  for  solution,  viz. : 
"Liebig  (Agricultural  Chemistry,  Amer.  edition,  page  184) 
says  that  the  nicotina  of  commercial  tobacco  does  not  pre-exist 
in  the  growing  plant,  but  is  the  result  of  the  fermentation  set 
up  during  the  curing  process.  Question. — If  this  be  true,  what 
is  the  active  principle  of  green  tobacco,  and  what  relation  does 
it  bear  to  nicotina  ?" 
Having  accepted  this  investigation,  the  author  found  himself 
unable  to  proceed  for  want  of  the  material,  and  consequently 
had  to  delay  it  till  the  tobacco  plant  bloomed  at  Philadelphia 
early  in  August  of  the  present  year.  Meanwhile,  however,  it 
was  determined  to  examine  the  seeds  of  tobacco,  assuming  them 
to  be  the  most  active  part  of  the  plant,  judging  from  analogy 
as  regards  lobelia,  stramonium,  hyoscyamus,  etc.  Through  the 
the  kind  offices  of  Mr.  T.  Roberts  Baker,  of  Richmond,  Vir- 
ginia, two  pounds  of  the  seed,  in  good  condition,  were  procured 
last  spring.
