NEW  ESSENTIAL  OILS.1 
In  our  last  Report  we  mentioned  on  pages  82-83  two  new  oils — 
of  Evodia  simplex  and  Pilea — which  had  been  sent  to  us  by  the 
Syndicat  du  Geranium  Bourbon.  Of  a  third  oil,  which  we  had 
received  at  the  same  time,  we  did  not  then  give  a  description,  as 
that  oil  was  described  simply  as  oil  of  "  une  espece  nouvelle." 
Since  then  we  have  heard  from  Reunion  that  the  oil  is  obtained 
from  a  shrub  belonging  to  the  Rutacece,  which  de  Cordemoy  has 
described  under  the  name  of  Evodia  aubettia,  but  which  is  said  to 
have  been  known  already  for  a  long  time  under  the  name  Xanthox- 
ylum  aubertia.  This  plant  is  known  in  Reunion  under  the  name 
"  Catafaille  blanc,"  and  is  highly  esteemed  there  as  a  very  active 
remedy  for  wounds,  but  is  also  employed  as  a  diaphoretic  and  a 
blood-purifying  remedy.  Unfortunately  we  found  no  description  of 
this  variety  in  the  botanical  works  which  we  have  at  our  disposal ; 
we  are  also  unable  to  say  from  what  part  of  the  plant  the  oil  has  been 
obtained.  It  represents  a  yellowish-green  liquid  with  a  pronounced 
odor  like  parsley;  d15°  0-9052;  aD  — 620  io' ;  acid  No.  1-3;  ester 
No.  7-3  ;  ester  No.  after  acetylation  51-0.  The  solubility  in  90  per 
cent,  alcohol  is  not  complete,  and  even  with  10  vol.  alcohol  only  a 
very  cloudy  solution  is  obtained  ;  in  95  per  cent,  alcohol  the  oil 
makes  first  of  all  a  clear  solution,  but  when  more  than  2  vol.  are 
added  opalescence  occurs  owing  to  separation  of  paraffin. 
A  test  for  phellandrene  which  we  suspected  to  find  in  the  oil  had 
a  negative  result.  It  appears  from  the  ester  and  acetylation  num- 
bers that  the  oil  contains  only  very  small  quantities  of  ester-like 
and  alcoholic  constituents.
