ated  ipecacuanha  which  I  met  with  about  the  same  time  at  the  Phar- 
macie  Centrale  of  M.  Dorvault  confirmed  me  in  the  opinion  that  this 
question  was  worthy  of  investigation,  and  I  engaged  several  of  our 
students  successively  to  deal  with  it  in  their  inaugural  theses.  M. 
Georges  Durand,*  in  examining  the  structure  of  various  kinds  of  ipe- 
cacuanhas, pointed  out  that  the  striated  ipecacuanha  of  Vogl  did  not 
correspond  in  its  anatomical  characters  to  those  of  the  sort  so  named 
in  the  Guibourt  collection.  M.  Thenot,f  preparateur  of  natural  his- 
tory in  the  School  of  Pharmacy,  went  further,  and  showed  that  in  the 
collection  of  the  school  there  existed  in  reality  two  species  of  striated 
ipecacuanha  differing  considerably  in  their  anatomical  characters. 
This  result  was  afterwards  confirmed  by  M.  Charles  Menier,J  who, 
passing  in  review  all  the  true  and  false  species  of  ipecacuanhas,  sub- 
mitted them  to  a  microscopical  examination. 
It  thus  appeared  from  these  researches  that,  under  the  name  of  stri- 
ated ipecacuanha,  Writers  have  generally  confounded  two  very  distinct 
roots.  It  is  to  these  species  I  therefore  would  wish  to  refer,  in  order 
to  indicate  their  characters,  investigate  their  botanical  origin,  and 
establish  exactly  their  synonymy. 
The  two  sorts  are  so  different  in  their  dimensions  that^they  may  be 
designated  respectively  the  major  and  the  minor  striated  ipecacuanha. 
1.  The  Major  Striated  Ipecacuanha. — This  ipecacuanha  is~met  with 
in  moderately  long  fragments,  sometimes  attaining  a  length  of  nine 
or  ten  centimetres.  The  diameter  varies  between  five  and  nine  milli- 
metres. The  fragments  are  sometimes  rectilinear,  sometimes  sinuous, 
more  rarely  tortuous.  At  rather  distant  intervals  they  are^marked 
by  contractions  or  simply  circular  interstices.  The  whole  of  the  sur- 
face is  rather  coarsely  striated  longitudinally.  On^the  upper  side  the 
roots  often  bear  the  base  of  several  stems,  distinguishable  by  their 
much  smoother  surface.  The  color  of  this  ipecacuanha  is  a  tawny 
grey,  tending  sometimes  towards  a  reddish-brown, 
As  in  the  other  species  of  ipecacuanha,  a  section  of  this  root  re- 
veals a  cortical  portion  and  a  ligneous  meditullium.  The  cortical  por- 
tion is  soft  enough  to  allow  of  its  being  marked^  by  the  finger  nail.
