  Terminology 
  is 
  an 
  awkward 
  thing. 
  It 
  is 
  as 
  

   disagreeable 
  to 
  be 
  compelled 
  to 
  make 
  new 
  

   names, 
  as 
  to 
  be 
  constrained 
  to 
  use 
  the 
  old 
  

   faulty 
  ones. 
  Different 
  readers 
  may 
  associate 
  

   different 
  ideas 
  with 
  the 
  same 
  terms, 
  and 
  unfor- 
  

   tunately 
  this 
  is 
  the 
  case 
  with 
  much 
  of 
  the 
  

   terminology 
  of 
  the 
  science 
  of 
  heredity 
  and 
  

   variability. 
  What 
  are 
  species 
  and 
  what 
  are 
  

   varieties? 
  How 
  many 
  different 
  conceptions 
  

   are 
  conveyed 
  by 
  the 
  terms 
  constancy 
  and 
  varia- 
  

   bility? 
  We 
  are 
  compelled 
  to 
  use 
  them, 
  but 
  we 
  

   are 
  not 
  at 
  all 
  sure 
  that 
  we 
  are 
  rightly 
  under- 
  

   stood 
  when 
  we 
  do 
  so. 
  

  

  Gradually 
  new 
  terms 
  arise 
  and 
  make 
  their 
  

   way. 
  They 
  have 
  a 
  more 
  limited 
  applicability 
  

   than 
  the 
  old 
  ones, 
  and 
  are 
  more 
  narrowly 
  cir- 
  

   cumscribed. 
  They 
  are 
  not 
  to 
  supplant 
  the 
  older 
  

   terms, 
  but 
  permit 
  their 
  use 
  in 
  a 
  more 
  general 
  

   way.
