  on 
  the 
  upper 
  side, 
  together 
  with 
  upright 
  and 
  fallen 
  tubes, 
  

   were 
  thrown 
  on 
  the 
  screen. 
  

  

  The 
  anatomy 
  of 
  the 
  eyes, 
  legs 
  and 
  claws, 
  and 
  the 
  enormous 
  

   jaws, 
  both 
  of 
  the 
  male 
  and 
  female 
  spider, 
  were 
  shown 
  in 
  

   comparison 
  with 
  those 
  of 
  Epeira 
  diademata, 
  which 
  have 
  a 
  

   lateral 
  movement, 
  whereas 
  Atypus 
  strikes 
  vertically 
  with 
  its 
  

   jaws, 
  a 
  wonderful 
  provision, 
  which 
  enables 
  the 
  spider 
  to 
  obtain 
  

   its 
  food 
  without 
  quitting 
  the 
  tube. 
  The 
  actual 
  movements 
  of 
  

   the 
  jaws 
  of 
  Epeira 
  and 
  Atypus 
  were 
  shown 
  on 
  the 
  screen 
  by 
  

   the 
  author's 
  mechanical 
  arrangements 
  of 
  the 
  lantern. 
  Next 
  

   followed 
  the 
  internal 
  structure 
  of 
  the 
  jaws, 
  showing 
  the 
  poison- 
  

   bag 
  and 
  duct, 
  and 
  enormous 
  mass 
  of 
  muscle, 
  attached 
  to 
  the 
  

   huge 
  fangs 
  ; 
  also 
  the 
  labrum 
  and 
  labia 
  with 
  their 
  deadly 
  array 
  

   of 
  teeth, 
  with 
  which 
  the 
  spider 
  tears 
  a 
  rent 
  just 
  under 
  the 
  

   impaled 
  fly. 
  The 
  wonderful 
  spinning 
  organs, 
  six 
  in 
  number, 
  

   were 
  shown 
  in 
  various 
  positions, 
  with 
  their 
  multitude 
  of 
  dis- 
  

   charge 
  tubes, 
  through 
  which 
  the 
  never 
  ending 
  silk 
  flows 
  

   from 
  the 
  internal 
  silk 
  glands, 
  a 
  fine 
  photograph 
  of 
  which 
  was 
  

   thrown 
  on 
  the 
  screen. 
  

  

  In 
  the 
  third 
  part 
  of 
  his 
  paper, 
  Mr. 
  Enock 
  described 
  the 
  way 
  

   in 
  which 
  the 
  spider 
  obtained 
  its 
  food 
  without 
  seeing 
  it 
  or 
  

   quitting 
  the 
  tube. 
  A 
  fly 
  settles 
  on 
  the 
  outside 
  of 
  the 
  aerial 
  

   part 
  of 
  the 
  nest, 
  setting 
  in 
  motion 
  the 
  long 
  vertical 
  threads, 
  

   which 
  the 
  spider 
  stretches 
  from 
  top 
  to 
  bottom 
  of 
  the 
  nest 
  ; 
  she 
  

   immediately 
  runs 
  up 
  until 
  she 
  is 
  just 
  underneath 
  the 
  fly, 
  then 
  

   raising 
  her 
  fangs, 
  and 
  with 
  lightning-like 
  rapidity, 
  strikes 
  

   them 
  through 
  the 
  tube 
  and 
  into 
  the 
  fly, 
  the 
  labia 
  tear 
  a 
  hole 
  

   and 
  the 
  fly 
  is 
  dragged 
  through 
  and 
  down 
  to 
  the 
  bottom 
  of 
  the 
  

   tube, 
  where 
  the 
  spider 
  tackles 
  the 
  fly 
  and 
  pins 
  it 
  to 
  the 
  side, 
  

   returning 
  to 
  the 
  top 
  again 
  to 
  repair 
  the 
  nest 
  ; 
  this 
  she 
  does 
  

   by 
  carefully 
  drawing 
  the 
  edges 
  together, 
  then 
  reversing 
  her 
  

   position, 
  she 
  brings 
  the 
  broad 
  spinnerets 
  into 
  position 
  and, 
  

   with 
  a 
  few 
  movements 
  from 
  side 
  to 
  side, 
  quickly 
  and 
  most 
  

   securely 
  mends 
  the 
  hole. 
  Each 
  act 
  illustrating 
  the 
  capture 
  

   of 
  a 
  fly 
  was 
  shown 
  in 
  a 
  most 
  striking 
  manner 
  by 
  the 
  ingenious 
  

   arrangements 
  adopted 
  by 
  the 
  autlior 
  ; 
  first, 
  the 
  fly 
  was 
  seen 
  

   on 
  the 
  outside 
  of 
  a 
  sectional 
  view 
  of 
  the 
  aerial 
  part 
  of 
  the 
  tube, 
  

   followed 
  by 
  the 
  appearance 
  of 
  the 
  spider 
  underneath, 
  the 
  jaws 
  

   and 
  fangs 
  moved, 
  a 
  moment's 
  pause, 
  and 
  they 
  were 
  brought
