by  repeated  failures  to  obtain  the  dipentene  dihydrochlorate  and  tetrabro- 
mide.  There  is  also  in  camphor  oil  a  considerable  quantity  of  a  hydrocar- 
bon, boiling  about  260°  to  270°,  from  which  was  obtained  the  hydrochloric 
acid  compound,  melting  at  117°,  characteristic  of  the  sesquiterpene  cube- 
ben  e.  In  the  highest  boiling  fractions  of  camphor  oil  occurs  an  intensely 
blue  colored  oil,  which  is  probably  identical  with  the  constituent,  boiling  at 
about  the  same  temperature,  occurring  in  chamomile,  millefolium,  worm- 
wood and  other  oils.  The  constituents  of  camphor  oil  found  up  to  the 
present  are —

Cananga  Oil. — The  opinion  is  expressed  that  the  finer  sorts  of  Java  can- 
anga  oil  can  be  used  for  all  purposes  for  which  the  ordinary  qualities  of 
ylang-ylang  oil  suffice,  since  both  oils  are  derived  from  the  same  plant  and 
the  extraordinary  differences  in  quality  are  due  to  the  more  or  less  perfect 
methods  of  preparation. 
Chamomile  Oil. — In  order  to  prevent  as  much  as  possible  the  original  blue 
color  of  this  oil  from  changing  to  green  it  is  recommended  that  it  should  be 
protected  carefully  from  the  influence  of  light  and  heat. 
VAKIETTES. 
Antipyrin  is  stated  by  Dr.  Herbert  Snow  (Brit.  Med.  Jour.)  to  relieve  the 
pain  of  incurable  cancer,  and  to  act  best  when  given  with  morphine,  the 
analgesic  effect  of  which  it  greatly  enhances. 
Lactic  Acid  in  Tuberculous  Diarrhoea. — Segarj7  and  Aune  recommend 
lactic  acid,  2,  6,  or  8  grams  in  twenty -four  hours,  in  the  treatment  of  diarrhoea 
of  phthisis.  They  report  9  successful  cases. — Jour.  Amer.  Med.  Assoc.,  March

Creasote  in  Phthisis. — In  the  clinik  of  Dr.  Verstracten  (Rev.  gen.  Clin,  et 
Thera.),  creasote  has  been  found  of  service  in  phthisis.  It  may  be  given 
in  the  following  ways  : — 
(1)  .  One  part  may  be  mixed  with  20  of  cod  liver  oil.  Of  this  mixture  & 
to  6  teaspoonfuls  must  be  administered  daily. 
(2)  .  It  may  be  combined  with  an  equal  part  of  almond  oil,  and  five  to  ten 
drops  of  the  compound  given  three  times  daily  in  two  tablespoonfuls  of 
warm  milk  or  broth.
