C10H18O  boiling  at  176°,  this  could  not  be  obtained  pure  simply  by 
fractional  distillation  but  by  application  of  Wallaces  method  (passing 
dry  HC1  through  the  chilled  fraction,  draining  the  crystalline  magma, 
decomposing  this  with  water,  warming  with  dilute  K<  )H,  washing  the 
separated  oil  with  water,  drying  and  distilling  over  metallic  sodium) 
it  was  obtained  ;  3,  a  camphor-like  body  boiling  between  195  and  200° 
which  could  not  be  isolated  perfectly  pure,  but  its  behavior  towards 
metallic  sodium  and  the  results  of  an  ultimate  analysis  point  towards 
the  formula  C10H16O.  The  so-called  myrtol  was  found  to  be  a  mixture 
of  dextrogyre-pinene  and  cineol  and  is  more  appropriately  called 
rectified  myrtle  oil.  The  use  of  myrtol  is  recommended  to  be  discon- 
tinued, giving  way  to  eucalyptol  identical  with  cineol  ;  the  presence 
of  the  terpene  and  the  irritating  effect  of  this  substance  on  the  respir- 
atory organs  being  the  cause  for  the  above  suggestion. — Arch,  der

Mercurial  ointment  is  made  by  G.  Greuel  by  triturating  100  gms. 
mercury  with  15  grams  anhydrous  lanolin,  containing  20  per  cent, 
olive  oil,  until  the  mercury  is  extinguished  under  a  lense  magnifying 
5  diameters,  and  incorporating  with  an  anhydrous  semi-fluid  mixture 
of  115  gms.  lard  and  70  gms.  mutton  suet,  The  success  of  the 
method  depends  upon  using  material  entirely  free  from  water ;  one 
kilogram  ointment  can  be  made  in  from  one  to  one  and  a  half  hours.

To  remedy  rancidity  in  oils,  H.  Hager  uses  alcohol  of  85-87  per 
cent.,  which  by  dissolving  the  free  fatty  acids  renders  the  oil  again 
sweet  and  fit  for  use ;  one  volume  of  the  oil  warmed  to  35°  C.  is 
thoroughly  and  repeatedly  agitated  during  twelve  hours  with  one  to 
one  and  a-quarter  volumes  of  alcohol,  allowed  to  separate  and  the 
upper  (alcoholic)  layer  removed.  The  oil  is  shaken  a  second  and,  if 
necessary,  a  third  time  with  half  a  volume  alcohol;  proceeding  as 
above  from  a  rancid  olive  oil  (six  to  eight  years  old)  0*86  per  cent,  free
