ture of  Cedrela  is  in  general  smaller-celled  and  less  elongated, 
as  compared  with  cinchona;  but  the  cells  of  the  liber  are  a  good 
deal  longer.  Another  marked  difference  is  in  the  arrangement 
of  these  cells,  which  in  Cedrela  are  placed  in  rows  bj  bundles, 
while  in  cinchona  they  are  irregularly  interspersed. — (Schweiz.

ON  THE  BARK  OF  MILLINGTONIA  HORTENSIS,  Lin.  fil., 
BIGNONIACE^. 
By  Dr.  H.  Hollandt. 
The  bark  which  was  obtained  from  Dr.  A.  Fliickiger,  and 
which  is  highly  esteemed  in  Java  as  a  febrifuge,  consists  of  quills, 
Ij  feet  in  length  and  IJ  lines  thick.  The  external  corky  por- 
tion is  IJ  times  thicker,  and  may  be  readily  separated  in  small 
pieces  from  the  internal  portion.  The  surface  is  of  a  brownish 
yellow  color,  and  longitudinally  irregularly  fissured.  The  fis- 
sures frequently  show  on  their  margin  different  layers,  indicated 
by  darker  and  lighter  stripes.  Transverse  fissures  are  not  fre- 
quent and  always  short.  The  last  is  tough,  fibrous,  and  may  be 
separated  lengthwise  in  lamellse.  The  inner  surface  is  smooth 
and  of  a  lighter  or  darker  cinnamon  color.  The  parenchyma  of 
the  primary  bark  adheres  closely  to  the  bast  as  a  thin  brown 
layer  of  a  resinous  lustre,  which  may  be  readily  removed  from 
the  corky  portion. 
The  taste  is  rather  insipid,  mucilaginous,  not  bitter.  The 
bark  is  inodorous,  but  the  reddish-brown  powder  has  in  large 
quantities  a  somewhat  musty  odor,  reminding  faintly  of  cinchona. 
Under  the  microscope  the  corky  layer  shows  long  rows  of 
radial  cells,  with  wavy  walls,  to  which  are  joined  the  somewhat 
compressed  and  tabular  cells  of  the  external  parenchyma  of  the 
primary  bark,  exhibiting  upon  a  tangential  section,  hexagonal 
tables,  with  moderately  thick  walls  and  superficial  dots,  the 
angle  of  the  hexagon  never,  but  always  one  of  its  sides  lying 
upwards  and  downwards.    The  middle  parenchyma  or  coUen-
