Perfumes  in  Flowers, 
kind  with  stems  of  mast-like  straightness  and  clear  whiteness  sc 
close  together  in  the  forest  as  to  allow  them  space  only  towards  the 
summit  to  send  their  scanty  branches  and  sparse  foliage  to  the  free 
light. 
The  distillation  of  the  oil  was  first  initiated  by  Baron  Von  Mueller- 
E.  amygdalina  yields  more  oil  than  any  of  the  other  varieties,  and 
is  therefore  almost  solely  employed  for  the  purposes  of  distillation. 
It  is  also  one  of  the  best  for  subduing  malarious  effluvia  in  fever 
regions,  although  it  does  not  grow  abroad  quite  so  well  or  quickly 
as  E.  Globulus 
The  respective  hygienic  value  of  various  trees  may  to  some  extent 
be  judged  by  the  percentage  of  oil  in  their  leaves,  as  stated  below. 
The  lesser  quantity  of  oil  in  E.  Globulus  is  compensated  for  by 
vigor  of  its  growth,  and  early  copiousness  of  its  foliage.  It  readily 
adapts  itself  to  other  climates  and  hence  abroad  nearly  all  varieties 
of  the  oil  are  known  as  Globulus.  During  the  last  twenty  years 
the  blue  gum  has  come  into  high  repute  as  a  sanitary  tree  A 
high  authority  states  that  the  sewage  system  of  large  towns  in 
warm  climes  would  be  simplified  if  each  house  had  the  ever  green 
gum  tree  in  the  back  yard.  The  disinfecting  and  deodorizing 
virtues  of  the  tree  are  unquestionable. 
Flesh  of  any  kind  is  as  well  preserved  by  eucalyptus  as  by  crea- 
sote,  while  beef  sprinkled  with  it  will  dry  hard  without  putrefac- 
tion. It  is  fatal  to  bacteria  and  other  microorganisms.  It  may  be 
injected  into  the  veins  a"nd  arteries  of  cadavers  for  purposes  of 
preservation.    It  is  also  a  good  admixture  in  dressing  gangrene. 
The  insufficient  nature  of  the  micro-chemical  methods  usually 
employed  has  so  far  prevented  an  exact  knowledge  being  obtained 
Per  Cent,  of  Oil.
