constants  will  show:  d15Q  0-9123;  aD — 0°  15';  aldehyde-content 
about  60  per  cent.  The  oil  dissolves  in  o  8  volume  80  per  cent, 
alcohol,  but  when  further  diluted  heavy  cloudiness  occurs ;  the  be- 
havior towards  90  per  cent,  alcohol  is  the  same.  The  last-named 
property  also  belongs  to  the  West  Indian  distillates,  and  the  those 
obtained  in  the  Cameroons.1 
We  would  finally  mention  the  oil  from  Hardwickia  binata  Roxb, 
(Oil  of  ennaikulavd)  which  has  been  sent  to  us  from  London.  The 
tree  which  is  found  in  British  India  belongs  to  the  Leguminosae- 
The  balsam  has  a  red-brown  color,  green  when  in  a  very  thin  film, 
and  shows  a  green  fluorescence.  The  odor  is  peculiar,  and  not  ex- 
actly pleasant;  d150  1-0021  ;  acid  number  96-15  ;  ester  number  12-31  ; 
insoluble  in  10  volumes  80  per  cent,  alcohol.  On  steam-distillation 
about  44  per  cent,  of  a  colorless  fairly  mobile  oil  passed  over,  whilst 
a  brittle  green  resin  remained  behind.  The  distillate  had  the  fol- 
lowing constants : 
d150  0-9062  ;  <zD  —  70  42' ;  acid  number  o  85  ;  ester  number  2  88  \ 
soluble  in  about  5  and  more  volumes  95  per  cent,  alcohol. 
Of  oils  distilled  by  ourselves  we  mention  the  following  novelties  r 
Oil  from  bay  berries  from  the  Bermuda  Islands.  The  yellow 
brown  oil  has  an  aromatic  odor  which,  however,  clearly  differs  from 
that  of  the  ordinary  bay  oil.  The  yield  of  oil  amounted  to  3  66  per 
cent;  d15D  1-0170;  aD — 7°  3';  phenol-content  73  per  cent.;  sol- 
uble in  15  volumes  70  per  cent,  alcohol,  cloudiness  when  more  than 
about  4  volumes  were  added;  soluble  in  0  5  and  more  volumes  80 
per  cent,  alcohol. 
The  phenols  consist  of  eugenol  (melting  point  of  the  benzoyl- 
compound  about  700).  The  non-phenols  contain  abundant  quanti- 
ties of  1-phellandrene  (melting  point  of  the  nitrite  recrystallized  from 
acetic  ether  1030  to  1040);  myrcene,  however,  does  not  appear  to 
be  present  in  the  oil. 
Oil  of  Artemisia  annua  L.  (Composite).  The  oil  obtained  in  a 
yield  of  0-29  per  cent,  from  the  green  herb  cultivated  by  ourselves, 
has  a  lemon-yellow  color  and  a  pleasant,  refreshing  odor,  reminding 
distantly  of  sweet  basil.    The  specific  gravity  was  08912  at  15°,
