  in 
  consequence 
  of 
  this, 
  exercises 
  tlie 
  property 
  of 
  adhesion 
  to 
  the 
  greatest 
  

   extent 
  in 
  respect 
  to 
  its 
  own 
  parts, 
  hence 
  it 
  coalesces 
  in 
  those 
  annular 
  

   elevations 
  which 
  form 
  the 
  principal 
  feature 
  in 
  the 
  cohesion 
  figures 
  of 
  Prof. 
  

   Tomlinson. 
  

  

  I 
  will 
  conclude 
  this 
  paper 
  by 
  informing 
  you 
  that 
  I 
  consider 
  this 
  change 
  

   of 
  oil 
  into 
  resinoid 
  substances 
  helps 
  largely 
  to 
  produce 
  those 
  rapid 
  changes 
  

   of 
  colour 
  which 
  oil 
  exhibits 
  when 
  exposed 
  to 
  the 
  air 
  upon 
  a 
  surface 
  of 
  water; 
  

   indeed, 
  it 
  appears 
  to 
  me 
  that 
  the 
  effect 
  of 
  those 
  chemical 
  changes 
  which 
  

   must 
  take 
  place 
  in 
  certain 
  liquids 
  when 
  exposed 
  to 
  the 
  air 
  or 
  brought 
  into 
  

   contact 
  with 
  each 
  other, 
  has 
  been 
  ignored 
  by 
  those 
  persons 
  Avho 
  have 
  

   hitherto 
  investigated 
  the 
  subject 
  of 
  the 
  flow 
  of 
  hquids 
  upon 
  each 
  other.
