be  moderate  ;  the  filtrate,  as  stated  must  be  perfectly  clear,  as 
otherwise  the  preparation  becomes  more  or  less  turbid.  Although 
only  a  secondary  consideration,  it  will  be  observed  that  by  this 
process  alcohol  is  economized,  the  amount  used  being  not  half 
the  quantity  required  by  the  officinal  process,  and  entirely  recov- 
erable by  distillation,  which  is  not  the  case  when  a  portion  is 
absorbed  by  the  drug. 
If  this  process  should  meet  the  approval  of  the  Association, 
I  would  suggest  that  a  fluid  extract  of  seneka  and  a  compound 
fluid  extract  of  squills  and  seneka  could  be  prepared  according 
to  this  process,  which  would  afford  a  ready  means  of  preparing 
syrup  of  seneka  and  compound  syrup  of  squills.

TALL  TREES  IN  AUSTRALIA. 
It  would  appear  that  the  famous  "  mammoth  trees  "  of  Cali- 
fornia are  not  only  rivalled,  but  surpassed  in  height,  in  Victoria 
Colony,  Australia.  The  principal  facts  which  warrant  this  con- 
clusion, are  collected  by  Dr.  Ferdinand  Miiller,  Director  of  the 
State  Garden  at  Melbourne,  in  his  interesting  pamphlet,  recently 
issued,  upon  "  Australian  Vegetation,  considered  especially  in 
its  bearings  upon  the  occupation  of  the  Territory,  and  with  a 
view  of  unfolding  its  resources," — from  which  the  subjoined 
extracts  are  derived  : — 
"  The  marvellous  height  of  some  of  the  Australian,  and  especi- 
ally Victorian  trees,  has  become  the  subject  of  closer  investiga- 
tion, since  of  late,  particularly  through  the  miners'  tracks,  easier 
access  has  been  afforded  to  the  back-gullies  of  our  mountain-sys- 
tem. Some  astounding  data,  supported  by  actual  measurements, 
are  now  on  record.  The  highest  tree  previously  known  was  a 
Karri- Eucalyptus  [Eucalyptus  colossea),  measured  by  Mr.  Pem- 
berton  Walcott,  in  one  of  the  delightful  glens  of  the  Warren 
river  of  Western  Australia,  where  it  rises  to  approximately  400 
feet  high.  Into  the  hollow  trunk  of  this  Karri,  three  riders, 
with  additional  pack-horse,  could  enter  and  turn  in  it  without 
dismounting.    On  the  desire  of  the  writer  of  these  pages,  Mr.
