  Harper: 
  Inheritance 
  of 
  sugar 
  

  

  were 
  relatively 
  good 
  sweets 
  with 
  only 
  a 
  small 
  number 
  (two 
  to 
  

  

  two 
  

  

  m/'( 
  

  

  four 
  kernels 
  that 
  I 
  have 
  classed 
  as 
  dimpled 
  dents 
  and 
  thirteen 
  

   kernels 
  that 
  I 
  have 
  classed 
  as 
  flints. 
  This 
  ear 
  also 
  showed 
  six 
  

   kernels 
  in 
  the 
  special 
  class 
  of 
  intermediates 
  which 
  are 
  chimaera- 
  

   like, 
  with 
  one 
  half 
  plump 
  starchy 
  and 
  the 
  other 
  half 
  wrinkled 
  

   sugary 
  in 
  appearance. 
  This 
  is 
  the 
  highest 
  number 
  of 
  such 
  kernels 
  

   that 
  I 
  have 
  so 
  far 
  observed 
  in 
  a 
  single 
  ear. 
  I 
  have 
  classed 
  them 
  

   with 
  the 
  intermediates 
  in 
  my 
  general 
  averages 
  but 
  their 
  number 
  

   iR 
  too 
  small 
  to 
  aonreciablv 
  affect 
  the 
  insults.

   this 
  single

  the

  fluctuating

  of 
  characters

  a 
  further 
  fluctuating 
  ten-

  inheritance 
  of 
  the 
  modification 
  suggesting 
  the 
  possibility 
  

   of 
  obtaining 
  a 
  fairly 
  pure 
  race 
  intermediate, 
  in 
  respect 
  to 
  the 
  

   characters 
  considered, 
  between 
  the 
  parent 
  races.
