  quire 
  any 
  shape 
  necessary 
  to 
  conform 
  to 
  the 
  outline 
  of 
  

   the 
  seed 
  ; 
  also 
  those 
  near 
  the 
  extremities 
  of 
  the 
  loculi 
  are 
  

   irregular 
  in 
  shape. 
  On 
  crushing 
  the 
  pulp 
  the 
  acid 
  juice 
  is 
  

   forced 
  out 
  ; 
  and 
  it 
  will 
  be 
  noticed 
  that 
  the 
  clubs 
  near 
  either 
  ex- 
  

   tremity 
  are 
  sometimes 
  harder 
  than 
  those 
  nearer 
  the 
  center 
  

   and 
  do 
  not 
  contain 
  as 
  much 
  juice. 
  The 
  cross 
  section 
  may 
  

   lay 
  bare 
  the 
  seeds 
  growing 
  from 
  the 
  inner 
  angles 
  of 
  the 
  lo- 
  

   culi 
  and 
  imbedded 
  among 
  the 
  pulp. 
  Sometimes 
  only 
  abor- 
  

   tive 
  seeds 
  are 
  found, 
  or 
  sometimes 
  abortive 
  and 
  developed. 
  

   In 
  the 
  center 
  of 
  the 
  section 
  will 
  be 
  seen 
  a 
  white, 
  spongy 
  circu- 
  

   lar 
  mass 
  whose 
  perimeter 
  is 
  formed 
  by 
  the 
  lines 
  of 
  the 
  inner 
  

   rounded 
  angles 
  of 
  the 
  loculi. 
  These 
  fines 
  are 
  curved 
  in 
  such 
  

   a 
  way 
  that 
  their 
  convexities 
  are 
  turned 
  toward 
  the 
  center 
  

   of 
  the 
  circle. 
  Here 
  the 
  same 
  division 
  of 
  the 
  walls 
  of 
  the 
  lo- 
  

   culi 
  will 
  be 
  noticed 
  as 
  at 
  the 
  back. 
  By 
  looking 
  closely 
  sev- 
  

   eral 
  spots 
  may 
  be 
  discovered 
  in 
  the 
  spongy 
  center 
  near 
  the 
  

   perimeter, 
  one 
  occuring 
  at 
  each 
  angle 
  formed 
  by 
  the 
  curved 
  

   lines 
  of 
  the 
  perimeter. 
  

  

  The 
  rind 
  is 
  of 
  the 
  lemon 
  color 
  about 
  one-third 
  of 
  its 
  thick- 
  

   ness, 
  the 
  other 
  two-thirds 
  being 
  white. 
  The 
  large, 
  dark 
  oil 
  

   pands 
  are 
  quite 
  conspicuous, 
  extending 
  even 
  inside 
  the 
  yel- 
  

   J.OW 
  part 
  into 
  the 
  white 
  part 
  of 
  the 
  rind. 
  By 
  looking 
  care- 
  

   fully, 
  many 
  small, 
  dark 
  specks 
  mav 
  be 
  distinguished 
  distrib- 
  

   uted 
  through 
  the 
  white 
  rind. 
  One 
  speck 
  may 
  be 
  found 
  at 
  

   the 
  center 
  of 
  the 
  back 
  of 
  each 
  loculus 
  and 
  also 
  one 
  m 
  the 
  

   angle 
  at 
  the 
  juncture 
  of 
  any 
  two 
  loculi. 
  

  

  ^he 
  cross 
  section 
  of 
  the 
  mature 
  lemon 
  presents 
  a 
  radial 
  

   arrangement 
  like 
  the 
  wheel 
  of 
  a 
  wagon 
  : 
  the 
  center 
  spongy 
  

   mass 
  being 
  the 
  hub, 
  the 
  white 
  part 
  of 
  the 
  rind 
  representing 
  

   the 
  felloes, 
  the 
  yellow 
  part 
  the 
  tire, 
  and 
  the 
  walls 
  of 
  the 
  lo- 
  

   culi 
  the 
  spokes," 
  while 
  the 
  wheel 
  is 
  made 
  solid 
  by
