ister,"  V,  33  ;  but  the  color  is  not  bright  enough.  It  is  also  figured  in 
the  Botanical  Magazine,"  v,  73.  Can  any  one  say  if  Convolvulus 
(^Batatas)  Jalapd^is  in  cultivation,  and  if  it  has  been  found  to  be  hardy? 
E.  purga  has,  as  will  be  seen,  roundish  tubers  of  variable  size,  those  of 
mature  growth  being  about  as  large  as  an  orange,  and  of  dark  color.. 
These,  as  we  have  said,  are  the  true  jalap  tubers. 
With  reference  to  the  foregoing  question  as  to  Convolvulus  Jalapay 
Mr.  J.  Tyerman,  of  Torquay,  writes  to  the  "Garden"  as  follows: 
"  There  is  a  plant  of  it  in  the  Botanic  Gardens  at  Liverpool,  where  it 
has  been  for  the  last  fourteen  or  fifteen  years,  growing  on  a  bed  of 
gravel,  the  roots  being  about  the  size  and  shape  of  the  double  cocoa 
nut.  I  do  not  think  it  has  been  tried  in  the  open  ground  ;  perhaps 
the  curator  (Mr.  J.  Richardson)  will  possibly  act  on  the  suggestion,, 
and  give  it  a  trial,  and  report  the  result.  Exogonium  purga  matured 
seeds  with  me  this  season  for  the  first  time  ;  these  are  now  in  the 
hands  of  Mr.  Thompson,  of  Ipswich,  and  I  have  no  doubt  that  it  has 
done  so,  and  much  more  freely,  in  the  College  Botanic  Gardens  at 
Dublin,  where  both  Mr.  Ellacombe's  and  my  own  plants  originally 
come  from,  nine  or  ten  years  ago.  Both  the  jalap  and  the  scammony 
grow  luxuriantly  with  me,  and  I  originally  intended  to  recommend 
theit  cultivation  on  a  large  scale  in  this  country  for  m.edicinal  purposes  -y 
but  I  find  that  although  they  grow  freely,  and  produce,  like  the  common 
bindweed,  abundance  of  fleshy  root-stems,  from  which  they  may  be 
readily  increased,  they  produce  but  slowly  the  tuberous  roots  from 
which  the  active  property  is  extracted;  and  those  are  very  deficient  in 
resin,  compared  with  prime  imported  samples.  Judging  from  my  short 
experience,  it  would  require  from  four  to  six  years  to  fully  mature  a 
crop,  which  would  render  it  impossible  in  this  country." — Pharm.  'Jour.y

DEER  TONGUE  IN  PERFUMERY. 
BY   ADOLPH   W.   MILLER,   M.  D.,  PH.  D. 
[Read  at  the  Pharmaceutical  Meeting,  February  iGth.) 
Deer  tongue,  or  Southern  vanilla  [Liatris  odoratissima.,  Willd.),  seems 
destined  to  become  a  commercial  staple  of  some  importance,  chiefly, 
so  far,  on  account  of  its  large  consumption  as  a  flavor  for  tobacco.  It 
is  stated  to  be  also  used  to  some  extent  in  the  South  for  the  purpose  of 
preserving  clothing,  woolen  fabrics,  etc,  from  the  attacks  of  moths.
