It  cannot  rise  much  above  that  point,  but  that  is  sufficient  for 
quite  dense  liquids.  The  retorts  are  also  of  copper  and  jacketed, 
■with  the  exception  of  that  for  spt.  etheris  nitrici,  which  is  of 
lead,  and  heated  by  a  coil  in  the  interior.  The  temperature  is 
easily  and  perfectly  controlled  ;  the  apparatus  is  well  adapted 
for  the  perfect  production  and  distillation  of  this  ether.  A 
much  higher  temperature  is  required  for  the  manufacture  of  sul- 
phuric ether  than  can  be  attained  by  its  use.  For  all  the  pur- 
poses of  drying,  distilling,  evaporating,  warming,  &c,  nothing  can 
more  convenient,  safe,  and  economical.  It  meets  the  require- 
ments of  sand  baths,  water  baths,  distillatory  apparatus,  dryers, 
&c,  and  will  warm  the  establishment  of  the  chemist  and  phar- 
maceutist, at  the  same  time.  The  amount  of  coal  consumed 
depends  of  course  upon  the  work  done.  But  I  have  found  fifty 
pounds  in  the  twenty  four  hours  to  be  sufficient  for  constnt  use 
in  the  laboratory,  and  for  heating  the  rooms.

NOTE  ON  THE  KINO  OF  EUCALYPTUS  KESINIFER.A. 
By  William  Procter,  Jr. 
Some  time  ago,  Dr.  Wood,  when  preparing  the  last  edition  of 
the  U.  S.  Dispensatory,  placed  in  my  hands  for  examination  a 
sample  of  Botany  Bay  kino,  accompanied  by  a  twelve  ounce 
bottle  of  the  juice  of  the  Eucalyptus  resinifera,  from  which  it  is 
produced.  A  condensed  statement  of  the  results  of  its  examina- 
tion will  be  found  in  a  note  at  page  454  of  the  11th  edition  of 
the  Dispensatory,  (1858.) 
These  specimens  are  entirely  authentic,  having  been  brought 
to  New  York  directly  from  Australia,  and  presented  to  Dr. 
Wood  by  Mr.  S.  W.  Osgood,  druggist,  of  the  former  place.  The 
examination  made  for  Dr.  Wood,  only  had  reference  to  the  kino 
itself,  the  drug  he  was  describing,  but  it  has  occurred  to  me 
that  it  may  be  of  some  interest  to  extend  the  inquiry  to  the 
juice  itself,  as  regards  the  proportion  of  solid  matter  it  contains, 
its  astringency,  and  other  properties,  and  offer  it  in  a  short 
note.
