Genuine  Volatile  Oil  of  Eucalyptus  Globulus  hardly  ever 
appears  in  the  market,  the  oil  being  almost  invariably  distilled  in  Aus- 
tralia from  the  leaves  of  £.  amygdalina,  which  contains  more  oil  than 
any  other  known  species  of  Eucalyptus.  E.  globulus,  of  which  100 
pounds  of  leaves  yield  about  6  ounces  of  oil,  grows  in  not  easily 
approachable  districts.  The  two  oils  resemble  each  other  very  much; 
that  of  E.  globulus  possesses,  however,  more  therapeutical  efficacy,  and 
is  alone  used  for  making  eucalyptol. — Pharm.  Ztg.,  April  9,  1879,  p.

Use  of  Pyrogallic  Acid  as  a  Haemostatic. — Prof.  Husemann  calls 
attention  to  the  excellent  results  obtained  by  Dr.  Vesey  with  pyrogallic 
acid  administered  in  0*05  doses,  at  intervals  of  one  or  several  hours,  as 
a  haemostatic  in  cases  of  hemorrhages  of  the  lungs  and  stomach,  and 
suggests  clinical  experiments  with  it  used  internally,  as  Vesey  recom- 
mends it ;  the  author  considers  it  a  probably  reliable  substitute  for  ergot.

Determination  of  Carbolic  Acid.  —  E.  Hoffmann  places  over  1  to 
2  cc.  pure  concentrated  H2S04,  in  a  test-tube  an  equal  volume  of  diluted 
carbolic-acid  solution,  containing  not  more  than  1  part  in  500  parts  of 
water,  and  drops  several  grains  of  powdered  saltpetre  into  the  liquid, 
when  the  presence  of  as  little  as  1  milligram  of  carbolic  acid  will  be 
indicated  by  the  immediate  appearance  of  violet  streaks  ;  on  shaking, 
the  whole  liquid  acquires  the  violet  color.    If  concentrated  HCI  is
