of  essential  oil ;  it  has  a  smell  very  similar  to  otto  of  rose,  and  is 
much  used  for  adulterating  that  valuable  article;  it  is,  moreover,  said 
to  be  frequently  adulterated  itself  with  the  oil  of  Andropogon,  which 
is  considerably  cheaper,  and  is  imported  in  large  quantities  from  the 
East. 
Next  to  the  genus  Pelargonium,  the  most  interesting,  perhaps,  with 
regard  to  its  products  is  Monsonia  or  Sarcocaulon.  The  plants  have 
mostly  fleshy  spiny  stems,  which  secrete  or  deposit  a  large  quantity 
of  a  waxy  or  resinous  substance  ;  S.  E  Heritieri  and  S.  Pater soni  arer 
perhaps,  more  highly  endowed  with  this  power  than  any  other  species. 
This  substance  seems  to  be  formed  in  the  bark,  and  in  such  large 
quantities,  that  the  stems  become,  to  all  appearance,  a  mere  mass  of 
wax,  moulded  to  the  form  and  shape  of  the  stem.  It  is  of  a  greenish- 
yellow  color  externally,  in  fracture  very  like  that  of  gamboge  but 
rather  more  transparent ;  it  burns  like  caoutchouc,  but  with  a  slightly 
aromatic  smell.  In  alcohol  it  becomes  softish  and  partially  plastic,, 
and  a  similar  effect  is  produced  upon  it  by  boiling  water.  It  breaks 
with  a  short  fracture,  like  a  resin,  so  that  it  seems  to  possess  a  combina- 
tion of  waxy,  resinous  and  elastic  properties.  As  the  stems  of  the 
plants  become  old  the  vegetable  tissues  seem  to  be  displaced  by  the 
formation  of  this  substance,  so  that  becoming  a  mass  of  inflammable 
matter,  they  are  used  by  the  natives  for  candles  or  torches.  Some 
fine  specimens  of  this  substance  are  in  the  Kew  collection.  The  root 
and  herb  of  Monsonia  ovata,  Cav.,  called  by  the  Hottentots  Keita,  are 
astringent,  and  are  used  by  them  in  dysentery. — Pharm.  Jour,  and

THE  EUCALYPTUS  GLOBULUS  AND  ITS  USE  IN  MEDICINE. 
The  employment  of  the  Eucalyptus  globulus  in  therapeutics  is  the 
subject  of  a  very  important  memoir  by  Professor  Gubler,  in  which  he 
expresses  an  opinion  that  it  will  probably  prove  to  be  a  remedy  worthy 
of  being  ranked  with  the  cinchona  alkaloids.  We  take  the  following 
particulars  from  the  Journal  de  Pharmacie  et  de  Chimie  for  December : 
The  Eucalyptus  globulus  belongs  to  the  Natural  Order  Myrtacece, 
which  furnishes  the  clove  {Caryophyllus  aromaticus),  oil  of  cajeput 
{Melaleuca  minor),  and  the  pimento  {Eugenia  Pimento).  It  is  one  of 
the  noblest  representatives  of  a  genus  that  contains  upwards  of  a 
hundred  species.    It  is  often  gigantic  in  size,  and  is  impregnated
