  Brain 
  of 
  Monkeys,

  3. 
  Destruction 
  of 
  the 
  angular 
  gyrus 
  (pli 
  courbe) 
  causes 
  blindness 
  of 
  the 
  

   opposite 
  eye, 
  the 
  other 
  senses 
  and 
  voluntary 
  motion 
  remaining 
  unaf- 
  

   fected. 
  This 
  blindness 
  is 
  only 
  of 
  temporary 
  duration, 
  provided 
  the 
  

   angular 
  gyrus 
  of 
  the 
  other 
  hemisphere 
  remains 
  intact. 
  When 
  both 
  

   are 
  destroyed, 
  the 
  loss 
  of 
  visual 
  perception 
  is 
  total 
  and 
  permanent. 
  

  

  4. 
  The 
  effects 
  of 
  electrical 
  stimulation, 
  and 
  the 
  results 
  of 
  destruction 
  

   of 
  the 
  superior 
  temporo-sphenoidal 
  convolutions, 
  indicate 
  that 
  they 
  are 
  

   the 
  centres 
  of 
  the 
  sense 
  of 
  hearing. 
  (The 
  action 
  is 
  crossed.) 
  

  

  5. 
  Destruction 
  of 
  the 
  hippocampus 
  major 
  and 
  hippocampal 
  convo- 
  

   lution 
  abolishes 
  the 
  sense 
  of 
  touch 
  on 
  the 
  opposite 
  side 
  of 
  the 
  body. 
  

  

  6. 
  The 
  sense 
  of 
  smell 
  (for 
  each 
  nostril) 
  has 
  its 
  centre 
  in 
  the 
  subi- 
  

   culum 
  cornu 
  ammonis, 
  or 
  tip 
  of 
  the 
  uncinate 
  convolution 
  on 
  the 
  same 
  

   side. 
  

  

  7. 
  The 
  sense 
  of 
  taste 
  is 
  localized 
  in 
  a 
  region 
  in 
  close 
  proximity 
  to 
  the 
  

   centre 
  of 
  smell, 
  and 
  is 
  abolished 
  by 
  destructive 
  lesion 
  of 
  the 
  lower 
  part 
  

   of 
  the 
  temporo-sphenoidal 
  lobe. 
  (The 
  action 
  is 
  crossed.) 
  

  

  8. 
  Destruction 
  of 
  the 
  optic 
  thalamus 
  causes 
  complete 
  anaesthesia 
  of 
  the 
  

   opposite 
  side 
  of 
  the 
  body. 
  

  

  9. 
  Ablation 
  of 
  the 
  occipital 
  lobes 
  produces 
  no 
  effect 
  on 
  the 
  special 
  

   senses 
  or 
  on 
  the 
  powers 
  of 
  voluntary 
  motion, 
  but 
  is 
  followed 
  by 
  a 
  state 
  

   of 
  depression 
  and 
  refusal 
  of 
  food, 
  not 
  to 
  be 
  accounted 
  for 
  by 
  mere 
  con- 
  

   stitutional 
  disturbance 
  consequent 
  on 
  the 
  operation. 
  The 
  function 
  of 
  

   these 
  lobes 
  is 
  regarded 
  as 
  still 
  obscure, 
  but 
  considered 
  to 
  be 
  in 
  some 
  

   measure 
  related 
  to 
  the 
  systemic 
  sensations. 
  Their 
  destruction 
  does 
  not 
  

   abolish 
  the 
  sexual 
  appetite. 
  

  

  10. 
  After 
  removal 
  both 
  of 
  the 
  frontal 
  and 
  occipital 
  lobes, 
  an 
  animal 
  

   still 
  retains 
  its 
  faculties 
  of 
  special 
  sense 
  and 
  the 
  powers 
  of 
  voluntary 
  

   motion. 
  

  

  The 
  Society 
  then 
  adjourned 
  over 
  the 
  Whitsuntide 
  Recess, 
  to 
  Thursday, 
  

   May 
  27th.
