ON  THE  TREE  PRODUCING  RED  CINCHONA  BARK.

able  name  of  Cinchona  oblongifolia  may  be  safely  disposed  of. 
In  the  next  place,  in  order  to  give  some  greater  certainty  in  this 
attempted  identification  with  the  new  term,  I  must  mention  that 
I  wrote  to  Dr.  Weddell,  and  also  transmitted  to  him  some  of 
the  leaves.  He  says  (under  date  August  2nd)  in  reference  to 
"  Quinology :"  "  You  have  evidently  solved  one  of  its  most  in- 
teresting desiderata,"  and  (under  date  August  12th,  having  re- 
ceived the  leaves)  he  adds,  "  the  leaves  I  find  in  a  better  state 
of  preservation  than  I  might  have  expected  from  your  account. 
They  undoubtedly  appear  to  correspond  exactly  to  what  you  infer 
as  to  their  botanical  origin." 
I  have  thus  given  all  that  it  is  in  my  power  to  afford  at  pre- 
sent for  the  direct  elucidation  of  this  question.  It  remains  that  I 
add  one  or  two  indirect  but  confirmatory  notices.  First,  as  to 
the  Cinchona  colorada  de  Huaranda  proceeding  from  a  species 
called  by  Pavon  Cinchona  succirubra,  and  which  I  have  described 
in  vol.  xi.,  p.  497  of  this  Journal  as  commercial  red  bark.  In 
the  course  of  last  year  I  found,  at  Kew,  Ruiz  and  Pavon's  a 
botanical  specimen  of  this,  and  it  proves  to  be  also  a  Cinchona 
ovata,  akin  in  the  sub-membranaceous  character  of  the  leaves 
to  those  which  I  have  since  received  direct. 
lation :  "  The  following  is  the  statement  of  the  number  and  properties  of  the 
officinal  barks  inserted  by  Dr.  Mutis  in  the  periodicals  of  Santa  Fe  : 
En  la  Botanica — Cinchona.

Nervina  Muscular  Humoral  Visceral 
Febrifuga  Indircctamente  febrifugas" 
This  enumeration  of  qualities  for  the  bark  of  the  oblongifolia  clearly  points 
to  the  Quina  nova,  as  his  recognized  red  bark. 
The  bark  of  the  lancifolia  is  alone  admitted  to  be  directly  a  febrifuge. 
That  of  the  ovalifolia  can  only  act  through  the  kinovic  acid  it  contains.  Is 
this  inert,  or  has  it  any  action  on  the  human  system?
