The  ash  is  interesting  for  containing  iodine^  as  shown  by  C.  Wein- 
hold,  in  1865,  who  found  0*882  per  cent.  The  author  has  met  with 
it  constantly,  the  percentage  varying  between  '474  and  '105,  but  in 
other  parts  of  the  tree  it  could  not  be  detected.  The  ash  of  the  pulp 
contains  also  large  amounts  of  phosphoric  acid,  9*987  per  cent.,  ferric 
oxide,  11*38  per  cent.,  and  silica  15*162  per  cent. — Zeitsch.  Oest.  Apoth.

E7iodictyon  Calif ornicum,  Bentham — The  leaves  are  described  by  J. 
Moeller.  They  are  leathery,  lanceolate,  about  four  inches  (10  cm.) 
long,  about  half  an  inch  (1  to  1*5  cm.)  broad,  short  petiolate,  repand- 
dentate,  green  and  glossy  above,  dark  reticulate  and  gray  beneath. 
The  upper  epidermis  is  large-celled  and  covered  with  a  moderately 
tough  and  delicately  wavy-furrowed 
cuticle,  the  grooves  containing  many- 
celled  glands  upon  two-  or  three-celled 
stipes.  The  secretion  of  the  glands  is 
yellowish  green,  resinous,  soluble  in 
alkalies,  contains  numerous  needle- 
shaped  crystals,  and  covers  the  upper 
surface  sometimes  to  the  thickness  of 
•02  mm.  Under  the  thick  palissade 
layer  is  the  mesophyll  composed  of  stel- 
late cells,  which,  between  the  veins,  are 
in  contact  with  the  small-celled  epi- 
dermis of  the  lower  surface ;  many  of 
these  epidermal  cells  are  elongated  to 
thin  gray  felt-like  hairs.  The  primary 
nerves  contain  on  the  lower  side  a  thick 
layer  of  collenchyma,  and  a  palissade 
layer  is  formed  in  the  angles  of  the  secondary  nerves.  The  epidermis 
alongside  of  the  nerves  is  smooth,  and  contains  only  few  glandular 
hairs  like  those  of  the  upper  surface.  The  parenchyma  is  free  from 
tannin;  many  cells  contain  groups  of  oxalate  crystals.    Strong  alco-
