﻿Report 
  of 
  the

  The 
  Museum 
  is 
  fortunate 
  in 
  having 
  secured 
  Dr. 
  Henry 
  E. 
  

   Crampton 
  to 
  take 
  charge 
  of 
  the 
  department. 
  Dr. 
  Crampton 
  

   is 
  a 
  graduate 
  of 
  Columbia 
  University 
  and 
  for 
  several 
  years 
  

   has 
  held 
  the 
  Chair 
  of 
  Zoology 
  at 
  Barnard 
  College. 
  He 
  has 
  

   had 
  wide 
  experience 
  as 
  a 
  teacher; 
  he 
  is 
  familiar 
  with 
  museum 
  

   methods, 
  and 
  is 
  well 
  known 
  as 
  an 
  investigator 
  and 
  writer. 
  

   He 
  assumed 
  his 
  duties 
  January 
  1, 
  1909. 
  

  

  The 
  scientific 
  staff 
  of 
  the 
  department 
  has 
  been 
  further 
  

   strengthened 
  by 
  the 
  following 
  appointments: 
  Dr. 
  Frank 
  E. 
  

   Lutz, 
  a 
  research 
  assistant 
  in 
  the 
  Carnegie 
  Institution 
  at 
  Cold 
  

   Spring 
  Harbor, 
  Long 
  Island, 
  as 
  an 
  Assistant 
  Curator; 
  Dr. 
  

   Alexander 
  Petrunkevitch 
  as 
  Honorary 
  Curator 
  of 
  Arachnida, 
  

   and 
  Dr. 
  Aaron 
  L. 
  Treadwell 
  as 
  Honorary 
  Curator 
  of 
  Annulata. 
  

  

  During 
  the 
  interim 
  the 
  affairs 
  of 
  the 
  department 
  were 
  in 
  

   charge 
  of 
  Mr. 
  Roy 
  W. 
  Miner, 
  the 
  Assistant 
  Curator, 
  who 
  dis- 
  

   charged 
  his 
  manifold 
  duties 
  most 
  efficiently. 
  

  

  The 
  attention 
  of 
  the 
  staff 
  has 
  been 
  largely 
  devoted 
  to 
  the 
  

   exhibition 
  collections. 
  The 
  installation 
  has 
  been 
  designed 
  to 
  

   present 
  a 
  bird's-eye 
  view 
  of 
  the 
  animal 
  kingdom 
  and 
  to 
  empha- 
  

   size 
  the 
  relationship 
  existing 
  between 
  the 
  groups. 
  Many 
  of 
  

   the 
  animals 
  are 
  so 
  small 
  that 
  it 
  is 
  practically 
  impossible 
  to 
  

   demonstrate 
  their 
  structure 
  by 
  preserved 
  specimens, 
  but 
  by 
  

   making 
  carefully 
  prepared 
  enlarged 
  models 
  it 
  is 
  possible 
  to 
  

   give 
  the 
  visitor 
  an 
  accurate 
  idea 
  of 
  their 
  structure 
  and 
  of 
  their 
  

   relations 
  to 
  one 
  another 
  and 
  to 
  man. 
  

  

  The 
  principal 
  additions 
  to 
  the 
  exhibition 
  series 
  have 
  been 
  

   the 
  models 
  prepared 
  by 
  Dr. 
  B. 
  E. 
  Dahlgren 
  and 
  his 
  assistants. 
  

   These 
  include 
  models 
  of 
  the 
  anatomy 
  of 
  certain 
  parasites; 
  the 
  

   anatomy 
  of 
  the 
  common 
  lobster, 
  and 
  a 
  series 
  of 
  models 
  show- 
  

   ing 
  the 
  development 
  of 
  the 
  egg 
  in 
  the 
  Ascidians. 
  

  

  The 
  offices 
  of 
  the 
  department 
  and 
  many 
  of 
  the 
  study 
  col- 
  

   lections 
  have 
  been 
  transferred 
  to 
  the 
  rooms 
  on 
  the 
  fifth 
  floor 
  

   of 
  the 
  new 
  west 
  wing. 
  

  

  In 
  the 
  spring, 
  Dr. 
  Dahlgren 
  and 
  Mr. 
  H. 
  Mueller 
  visited 
  the 
  

   Bahama 
  Islands 
  in 
  search 
  of 
  material 
  intended 
  for 
  use 
  in 
  the 
  

   reproduction 
  of 
  a 
  coral 
  reef. 
  They 
  made 
  extensive 
  studies 
  of 
  

   several 
  reefs 
  and 
  secured 
  a 
  large 
  number 
  of 
  choice 
  specimens, 
  

   including 
  an 
  exceptionally 
  fine 
  example 
  of 
  a 
  madrepore 
  coral 
  

   which 
  measures 
  ten 
  feet 
  in 
  length 
  and 
  weighs 
  nearly 
  two 
  tons.
