  [September, 
  

  

  The 
  Horticultural 
  Department 
  of 
  the 
  Cornell 
  University 
  Experiment 
  

   btation 
  IS 
  making 
  a 
  large 
  and 
  important 
  collection 
  of 
  cultivated 
  plants. 
  

   Collectors 
  are 
  sent 
  to 
  leading 
  nurseries 
  and 
  botanists 
  are 
  employedin 
  

   niany 
  parts 
  of 
  the 
  country 
  to 
  collect 
  the 
  cultivated 
  plants 
  from 
  commer- 
  

   cial 
  establishments. 
  Everything 
  upon 
  the 
  Cornell 
  grounds 
  is 
  preserved, 
  

   and 
  recently 
  Professor 
  L. 
  H. 
  Bailey 
  has 
  turned 
  over 
  to 
  the 
  University 
  

   his 
  whole 
  collection 
  of 
  cultivated 
  plants. 
  Not 
  only 
  the 
  species, 
  but 
  all 
  

   cultivated 
  varieties 
  are 
  preserved. 
  This 
  is 
  probably 
  the 
  first 
  distinct 
  at- 
  

   tempt 
  of 
  this 
  kind 
  in 
  this 
  country. 
  

  

  The 
  outer 
  laykr 
  of 
  the 
  endosperm 
  of 
  the 
  seeds 
  of 
  grasses 
  has 
  

   ^ 
  bean 
  considered 
  as 
  a 
  reservoir 
  of 
  nitrogenous 
  substances, 
  altliough 
  

   several 
  writers 
  have 
  suggested 
  that 
  it 
  was 
  either 
  a 
  conducting 
  tissue 
  for 
  

   diastase 
  or 
  a 
  ferment-producing 
  layer. 
  Dr. 
  G. 
  Haberlandt 
  has 
  now 
  con- 
  

   vinced 
  himself 
  by 
  experimental 
  researches 
  that 
  it 
  can 
  no 
  longer 
  be 
  con- 
  

   smered 
  as 
  belonging 
  to 
  the 
  storage 
  system, 
  but 
  that 
  during 
  the 
  time 
  of 
  

   germmation 
  it 
  produces 
  and 
  excretes 
  diastase, 
  belonging 
  therefore 
  to 
  the 
  

   glandular 
  system. 
  The 
  anatomical 
  structure 
  of 
  the 
  "aleurone 
  layer" 
  

   auring 
  germination 
  is 
  exactly 
  that 
  of 
  glandular 
  cells. 
  Moreover, 
  a 
  bit 
  

   tins 
  tissue 
  separated 
  from 
  the 
  grain 
  and 
  carefully 
  washed 
  will, 
  if 
  placed 
  

   t^u°T^t^'^'* 
  ^^^^^^ 
  corrode 
  the 
  grains 
  and 
  finally 
  dissolve 
  them, 
  a 
  re- 
  

   sult 
  which 
  was 
  not 
  obtained 
  in 
  control 
  experiments. 
  In 
  order 
  that 
  this 
  

   ormation 
  of 
  diastase 
  shall 
  begin 
  it 
  is. 
  necessary 
  that 
  at 
  least 
  a 
  portion 
  of 
  

   the 
  embryo 
  capable 
  of 
  growth 
  should 
  be 
  present.
