  Mr. 
  H._J. 
  Webber 
  {An 
  Nat.

  suggests 
  the 
  use 
  of 
  peridial 
  cell 
  

   ctiaracters 
  in 
  the 
  genus 
  ^cidium, 
  as 
  they 
  are 
  frequently 
  used 
  in 
  Eoes- 
  

   teha. 
  To 
  emphasize 
  his 
  point 
  he 
  calls 
  attention 
  to 
  the 
  diflFerences 
  in 
  

   certain 
  species. 
  

  

  MOLISCH 
  finds 
  that 
  the 
  tissue 
  under 
  the 
  epidermis 
  in 
  the 
  fruit 
  of 
  

   Capsicum, 
  which 
  appears 
  to 
  be 
  collenchyina, 
  and 
  has 
  been 
  designated 
  as 
  

   such, 
  gives 
  all 
  the 
  reactions 
  of 
  cork 
  cells, 
  the 
  walls 
  being 
  completely 
  su- 
  

   berised. 
  He 
  has 
  found 
  the 
  same 
  tissue 
  in 
  Solanum 
  melongena

  CoNWENTz 
  has 
  found 
  tyloses 
  in 
  the 
  tracheides 
  of 
  the 
  root 
  wood 
  of 
  the 
  

   tree 
  producing 
  the 
  gum 
  which, 
  fossilized, 
  is 
  called 
  amber. 
  Bits 
  of 
  the 
  

   wood, 
  found 
  imbedded 
  in 
  the 
  amber, 
  indicate 
  that 
  the 
  tree 
  was 
  a 
  species 
  

  

  ot 
  ricea. 
  Tyloses 
  also 
  occur 
  by 
  the 
  enlargement 
  of 
  the 
  epithelium 
  of 
  the 
  

   gum
