present  official  defeats  the  object  for  which  they  are  framed — 
namely,  to  ensure  that  only  genuine,  unmanipulated  articles  are 
offered  for  medicinal  use.  As  they  stand  at  present,  they  must 
have  a  directly  opposite  effect." 
The  real  efficient  and  crucial  test  and  requirement  for  the  value 
and  purity  of  a  santal  oil  is  the  content  of  santalol,  which  is  the 
efficient  agent  in  the  oil.  As  long,  hence,  as  a  santal  oil  contains  at 
least  90  per  cent,  of  santalol  by  assay,  it  matters  little  what  the 
remaining  10  per  cent,  are,  so  long  as  they  are  obtained  from  sandal- 
wood by  distillation.  The  point  we  wish  to  make  is  that  contrary 
to  the  views  of  Messrs.  Schimmel  &  Co.  we  consider  the  optical  rota- 
tion, acid  and  ester  numbers  as  distinctly  secondary  in  importance 
to  the  requirement  of  90  per  cent,  santalol.  Since  our  last  publi- 
cation, we  have  among  others  studied  the  distillation  of  oils  from 
the  following  lots  of  santal  oil  imported  by  us  from  India  direct: — 
I.  Seringapatam  Panjam. 
II.  Sagar  Banjam. 
III.  Chickmaglur  Ghat  Badala. 
IV.  Tarikere  Ghat  Badala. 
V.  Fraserpett  Parjjam.
