  Dr. 
  J. 
  M. 
  Janse 
  gives 
  a 
  voluminous 
  account 
  of 
  the 
  protoplasmic 
  

   movements 
  in 
  Caulerpa

  in

  After 
  

   studymg

  all 
  the 
  organs, 
  and 
  their 
  displacement 
  upon

  concludes 
  that 
  their 
  purpose 
  is 
  to 
  distribute 
  the 
  nutritive 
  materials 
  

   through 
  the 
  plant. 
  

  

  The 
  non 
  crystalized 
  coloring 
  matters 
  of 
  lichens 
  have 
  been 
  carefully 
  

   studied 
  by 
  Dr. 
  E. 
  Bachmann.^ 
  He 
  finds 
  sixteen 
  which 
  can 
  be 
  readily 
  dis- 
  

   tinguished 
  by 
  microchemical 
  means, 
  tive 
  greens, 
  one 
  blue, 
  four 
  reds 
  and 
  

   SIX 
  browns, 
  in 
  the 
  120 
  species 
  examined. 
  In 
  one 
  case 
  the 
  coloring 
  mat- 
  

   ter 
  occurred 
  in 
  drops 
  in 
  the 
  cell 
  contents; 
  in 
  two 
  cases 
  as 
  excretions 
  on 
  

   the 
  outer 
  surface 
  of 
  the 
  cell 
  membrane; 
  in 
  all 
  the 
  other 
  instances 
  it 
  was 
  

   found 
  in 
  the 
  cell 
  membrane 
  itself. 
  In 
  the 
  thallus 
  it 
  is 
  almost 
  always 
  in 
  

   the 
  cortical 
  region. 
  In 
  the 
  apothecium 
  it 
  may 
  be 
  in 
  any 
  part, 
  but 
  is 
  rare 
  

   m 
  the 
  hypothecium. 
  The 
  walls 
  of 
  the 
  asci 
  are 
  not 
  colored, 
  but 
  the 
  para- 
  

  

  pnyses. 
  In 
  the 
  cell 
  walls 
  the 
  middle 
  lamella 
  usually 
  contains 
  the 
  most 
  of 
  

   the 
  color.

  the 
  gist 
  of 
  his 
  paper 
  in 
  the 
  opening 
  paragraph, 
  which 
  

   we 
  preserve

  and

  as

  : 
  My 
  observations 
  on 
  differ- 
  

   ent 
  green 
  vegetative 
  parts 
  of 
  plants 
  in 
  constant 
  darkness 
  have 
  led 
  very 
  

   quickly 
  to 
  the 
  conclusion 
  that 
  the 
  destruction 
  of 
  the 
  chlorophyll 
  is 
  not 
  a 
  

   primary 
  effect 
  of 
  the 
  darkness, 
  but 
  that 
  the 
  chlorophyll 
  itself 
  may 
  persist 
  

   unaltered 
  for 
  a 
  long 
  time 
  in 
  darkness, 
  provided 
  that 
  the 
  cell 
  remains 
  

   alive; 
  on 
  the 
  contrary 
  that 
  the 
  destruction 
  of 
  chlorophyll 
  in 
  darkness 
  ia 
  

   only 
  a 
  secondary 
  phenomenon 
  which 
  appears 
  in 
  connection 
  with 
  the 
  dy- 
  

   ing 
  of 
  the 
  cell 
  on 
  account 
  of 
  the 
  lack 
  of 
  light, 
  as 
  a 
  symptom 
  of 
  the 
  empty- 
  

   ing 
  which 
  here 
  precedes 
  death, 
  analogous 
  with 
  the 
  destruction 
  of 
  chloro- 
  

   phyll 
  upon 
  the 
  autumnal 
  emptying 
  of 
  the 
  leaves. 
  

  

  The 
  first 
  annual 
  report 
  of 
  the 
  director 
  of 
  the 
  Missouri 
  Botanic 
  

   Garden 
  has 
  been 
  issued. 
  It 
  contains 
  a 
  statement 
  of 
  the 
  changes 
  that 
  

   are 
  being 
  made 
  in 
  the 
  Garden, 
  or 
  that 
  are 
  in 
  immediate 
  prospect. 
  In 
  

   order 
  that 
  the 
  development 
  of 
  the 
  plans 
  may 
  be 
  properly 
  noted, 
  a 
  map 
  

   of 
  the 
  grounds 
  on 
  a 
  large 
  scale 
  is 
  being 
  prepared. 
  The 
  remainder 
  of 
  

   the 
  report 
  contains 
  a 
  statement 
  of 
  the 
  policy 
  of 
  the 
  trustees 
  (as 
  already 
  

   published 
  in 
  this 
  journal), 
  the 
  announcement 
  of 
  the 
  establishment 
  of 
  

   ^e 
  garden 
  scholarships, 
  and 
  an 
  exposition 
  of 
  the 
  relations 
  of 
  the 
  Shaw 
  

   School 
  of 
  Botany 
  to 
  the 
  Garden. 
  The 
  director 
  requests 
  from 
  authors 
  

   copies 
  of 
  their 
  publications 
  for 
  the 
  library, 
  from 
  collectors 
  specimens 
  

   for 
  the 
  herbarium, 
  and 
  promises 
  all 
  feasible 
  assistance 
  in 
  work 
  calcu- 
  

   lated 
  to 
  promote 
  botanical 
  knowledge.
