  A 
  lot 
  of 
  sea-

  collected 
  by 
  the 
  Albatross

  and 
  report. 
  

  

  A 
  complete 
  working 
  series 
  of 
  American 
  fishes 
  is 
  a 
  great 
  desideratum 
  

   in 
  the 
  laboratory, 
  and 
  active 
  measures 
  have 
  been 
  taken 
  to 
  fill 
  out 
  the 
  

   reserve 
  collection 
  and 
  arrange 
  it 
  in 
  a 
  manner 
  convenient 
  for 
  ready 
  

   reference. 
  W^hile 
  the 
  small 
  size 
  of 
  the 
  laboratory 
  precludes 
  the 
  possi- 
  

   bility 
  of 
  having 
  a 
  large 
  series 
  of 
  specimens 
  on 
  hand, 
  there 
  is 
  ample 
  

   room 
  for 
  typical 
  examples 
  of 
  all 
  the 
  fresh-Avater 
  species 
  and 
  the 
  smaller 
  

   salt-water 
  ones. 
  

  

  A 
  special 
  collection 
  of 
  considerable 
  importance 
  has 
  been 
  begun, 
  

   consisting 
  of 
  carefully 
  identified 
  immature 
  fishes 
  of 
  various 
  sizes 
  and 
  

   ages, 
  more 
  especially 
  those 
  which 
  are 
  propagated 
  by 
  the 
  Commission 
  

   or 
  are 
  related 
  to 
  those 
  artificially 
  cultivated.
