(3.)  When  two  ethereal  solutions  were  made  simultaneously,  the 
one  with  crystallized  iodoform,  the  other  with  powdered  iodoform,  and 
using  red  glass  bottles,  the  first  preserved  its  yellow  tint,  the  second 
assumed  a  brown  color  after  a  few  days. 
Solubility. — Experiments  were  mide  with  pure  ether  of  65°  Baume 
(sp.  gr.  '724),  and  also  with  ethers  of  62°  and  56°,  the  temperature 
being  13°  C.    Eight  grams  of  tincture  obtained  with  these  ethers 
contained  iodoform  in  solution  respectively  to  the  following  extent: — 
Ether  of  65°  Baume    .        .        1*61  grams. 
"        62°     "  .  1-26  " 
56°     "       .       .       1-13  " 
The  iodine  being  equal  in  the  first  case  to  25*195  per  cent,  of  the 
ether;  in  the  second  to  13*691  per  cent.,  and  the  third  to  16  014  per 
cent.,  or  in  round  numbers,  at  65°  B.,  one-fourth;  at  62°  B.,  one- 
fifth,  and  at  56°  B.,  one-sixth. 
Tae  conclusions  drawn  by  the  authors  from  the  foregoing  experi- 
ments are — 
(1.)  To  employ  iodoform  in  the  crystalline  state. 
(2.)  To  m  ike  the  solution  in  a  red  glass  flask  by  simple  agitation. 
(3.)  To  use  the  following  proportions  : 
Crystallized  iodoform        .        .        1  gram. 
Ether  (60°  Baume)    ...        4  grams.

NOTES  OX  THE  MEDICINAL  PL  A.  NT  3  OP  THE  RUTAOE/E. 
By  John  R.  Johnson,  A.  L.  S., 
Curator  of  the  Museums,  Kew. 
The  Natural  Order  Rutacece,  as  at  present  constituted — that  is, 
including  as  tribes  such  groups  as  Zinthoxyleoe  and  Aurantiece,  which 
by  former  botanists  have  been  dignified  as  Natural  Orders — includes 
a  great  number  of  medicinal  and  economic  plants  ;  for  besides  such 
well-known  articles  as  rue,  buchu  or  barosma  leaves,  and  cusparia 
bark,  many  others  of  less  repute  are  brought  together.  We  purpose 
to  refer  to  those  which,  though  being  used  by  the  natives  of  the  coun- 
tries in  which  they  grow,  are  seldom  seen  except  in  museum  collec- 
tions in  this  country,  and  some  not  even  there.  In  the  tribe  Oaspa- 
riece,  besides  the  genus  Grdlipea,  which  is,  of  course,  well  known  as 
the  source  of  cusparia  bark,  occurs  Ticorea,  two  species  of  which  are
