that  of  spike  lavender  oil,  and  is  pale  yellow  in  color.  The  leaves 
yielded  0.49  per  cent,  of  volatile  oil,  having  the  following  constants : 
It  was  soluble  in  2.5  volumes  of  70  per  cent,  alcohol  at  150  C, 
becoming  cloudy  with  6  volumes.  Traces  of  caproic  and  acetic  acids 
were  found  and'  about  0.1  per  cent,  of  an  aldehyde,  which  was  not 
identified.  A  phenol  was  extracted  which  amounted  to  about  0.1 
per  cent,  of  the  original  oil.  It  gave  a  reddish-violet  coloration  with 
ferric  chloride,  but  no  evidence  of  the  presence  of  eugenol  was  ob- 
tained. On  fractionation  about  15  per  cent,  of  cineol  was  obtained, 
which  gave  an  iodole  compound  melting  with  decomposition  at  1160 
C.  Two  terpenes  were  separated,  one  giving  the  characteristic  nitrite 
of  a-pbellandrene,  melting  at  112-1130  C. ;  the  other  furnished  a 
tetrabromide,  melting  at  1240  C,  indicating  the  presence  of  dipentene, 
From  the  fraction  boiling  at  1 90-205 0  a  liquid  having  the  odor  and 
characters  of  linalool  was  obtained,  which  on  oxidation  with  chromic 
acid  yielded  citral.  Geraniol  was  isolated  from  the  fraction  boiling 
at  220-2350,  which  was  identified  by  conversion  into  the  acid  phthalic 
ester,  and  by  oxidation  to  citral.  The  diphenylurethane,  melting  at 
80-81  °,  was  also  prepared.  The  last  fraction  boiling  above  2350  was 
brown  and  rather  viscous.  By  distillation  over  sodium  under  re- 
duced pressure  a  colorless  oil  was  obtained  having  a  specific  gravity 
of  0.9320  and  boiling  between  245-2900,  but  the  amount  of  oil  was 
too  small  to  permit  further  investigation  of  this  product,  which  prob- 
ably contained  sesquiterpenes.  The  composition  of  this  oil  is,  there- 
fore, quite  different  from  the  oils  of  Pimenta  species  previously  ex- 
amined, which  include  oil  of  pimento  fruits,  from  Pimenta  officinalis, 
oil  of  bay  leaves,  from  Pimenta  acris,  and  two  varieties  of  P.  acris, 
one  containing  citral  and  the  other  having  a  characteristic  odor  of 
anise. — O.  D.  Roberts,  Journ.  Soc.  Chem.  Ind.,  40,  9,  491 ;  through
