  way 
  they 
  came. 
  It 
  is 
  no 
  dance 
  of 
  molecules, 
  but 
  a 
  chaotic 
  

   jostling. 
  Every 
  drop 
  of 
  liquid 
  is 
  in 
  a 
  state 
  of 
  commotion 
  

   and 
  turmoil 
  indescribable 
  (ibid., 
  p. 
  89). 
  Of 
  solids 
  relatively 
  

   little 
  is 
  known, 
  but 
  in 
  a 
  crystalline 
  solid 
  where 
  we 
  have 
  

   to 
  deal 
  with 
  fixed 
  architecture 
  there 
  can 
  be 
  no 
  translatory 
  

   motion. 
  " 
  But 
  vibratory 
  motion 
  in 
  constrained 
  paths 
  there 
  

   must 
  be 
  among 
  the 
  molecules 
  of 
  a 
  solid, 
  increasing 
  with 
  

   the 
  temperature 
  until 
  the 
  molecules 
  drag 
  their 
  anchors, 
  as 
  

   it 
  were, 
  and 
  the 
  substance 
  melts 
  ' 
  (ibid., 
  p. 
  9-i). 
  

  

  Thus 
  the 
  concept 
  of 
  matter 
  leads 
  us 
  to 
  a 
  very 
  ethereal 
  

   picture. 
  What 
  is 
  to 
  be 
  said 
  of 
  energy? 
  It 
  is 
  the 
  power 
  of 
  

   doing 
  work, 
  and 
  may 
  be 
  actual 
  or 
  potential, 
  in 
  motion 
  or 
  in 
  

   position. 
  But 
  except 
  when 
  it 
  changes, 
  its 
  existence 
  can 
  only 
  

   be 
  inferred. 
  Professor 
  Soddy 
  writes 
  : 
  " 
  The 
  Apostle 
  Paul 
  

   had 
  no 
  thought 
  of 
  physical 
  things 
  in 
  his 
  mind 
  when 
  he 
  used 
  

   the 
  words, 
  i 
  The 
  things 
  which 
  are 
  seen 
  are 
  temporal, 
  but 
  the 
  

   things 
  which 
  are 
  not 
  seen 
  are 
  eternal.' 
  But 
  the 
  words 
  can 
  

   be 
  applied 
  with 
  profit 
  to 
  illustrate, 
  perhaps 
  more 
  forcibly 
  

   than 
  any 
  other 
  single 
  sentence, 
  the 
  essential 
  nature 
  of 
  energy. 
  

   It 
  is 
  only 
  the 
  temporary 
  changes 
  in 
  the 
  form 
  and 
  relative 
  

   amount 
  of 
  energy 
  which 
  are 
  manifest. 
  So 
  long 
  as 
  energy 
  

   neither 
  changes 
  in 
  amount 
  nor 
  in 
  position, 
  it 
  belongs 
  to 
  the 
  

   unseen 
  and 
  eternal. 
  ISTo 
  direct 
  evidence 
  of 
  its 
  existence 
  can 
  

   be 
  obtained." 
  Yet 
  we 
  are 
  never 
  in 
  doubt 
  as 
  to 
  its 
  reality, 
  for 
  

   it 
  is 
  always 
  conserved. 
  And 
  besides 
  Matter 
  and 
  Energy 
  

   there 
  is 
  the 
  Ether 
  which 
  Sir 
  Oliver 
  Lodge 
  describes 
  as 
  " 
  the 
  

   universal 
  connecting 
  medium 
  which 
  binds 
  the 
  universe 
  to- 
  

   gether, 
  and 
  makes 
  it 
  a 
  coherent 
  whole 
  instead 
  of 
  a 
  chaotic 
  

   collection 
  of 
  independent 
  isolated 
  fragments. 
  It 
  is 
  the 
  ve- 
  

   hicle 
  of 
  transmission 
  of 
  all 
  manner 
  of 
  force, 
  from 
  gravita- 
  

   tion 
  down 
  to 
  cohesion 
  and 
  chemical 
  affinity; 
  it 
  is 
  therefore 
  

   the 
  storehouse 
  of 
  potential 
  energy. 
  ... 
  It 
  does 
  not
