  A 
  TLAIN 
  ANL 
  EASY 
  ACCOUNT 
  

  

  the 
  individuals 
  composing 
  which 
  are 
  so 
  exceedingly 
  

   fragile 
  that 
  such 
  a 
  method 
  of 
  preservation 
  will 
  not 
  avail. 
  

   In 
  many 
  such 
  cases 
  the 
  mould, 
  or 
  fungus, 
  may 
  be 
  

   mounted 
  at 
  once 
  in 
  the 
  ordinary 
  way 
  on 
  a 
  slide 
  for 
  the 
  

   microscope, 
  and 
  all 
  its 
  features 
  carefully 
  preserved. 
  

  

  The 
  greatest 
  difficulty 
  rests 
  with 
  the 
  larger 
  species, 
  

   such 
  as 
  many 
  of 
  the 
  Agarics 
  and 
  Boleti 
  ; 
  and 
  for 
  these 
  

   no 
  better 
  method 
  can 
  be 
  recommended 
  than 
  that 
  detailed 
  

   by 
  Klotsch, 
  himself 
  an 
  indefatigable 
  collector, 
  thirty 
  

   years 
  ago 
  : 
  — 
  

  

  " 
  With 
  a 
  delicate 
  scimitar-shaped 
  knife 
  or 
  scalpel, 
  

   such 
  as 
  is 
  found 
  in 
  a 
  surgeon's 
  instrument-case, 
  I 
  make 
  

   a 
  double 
  vertical 
  section, 
  through 
  the 
  middle, 
  from 
  the 
  

   top 
  of 
  the 
  pileus 
  to 
  the 
  base 
  of 
  the 
  stem, 
  so 
  as 
  to 
  remove 
  

   a 
  slice. 
  This, 
  it 
  will 
  be 
  at 
  once 
  seen, 
  shows 
  the 
  vertical 
  

   outline 
  of 
  the 
  whole 
  v 
  fungus, 
  the 
  internal 
  nature 
  of 
  its 
  

   stem, 
  whether 
  hollow, 
  or 
  spongy, 
  or 
  solid, 
  the 
  thickness 
  

   of 
  the 
  pileus, 
  and 
  the 
  peculiarities 
  of 
  the 
  gills, 
  whether 
  

   equal 
  or 
  unequal 
  in 
  length, 
  decurrcnt 
  upon 
  the 
  stem, 
  or 
  

   otherwise, 
  &c. 
  There 
  will 
  then 
  remain 
  the 
  two 
  sides, 
  

   or 
  nearly 
  halves 
  of 
  the 
  fungus, 
  which 
  each 
  in 
  itself 
  

   gives 
  a 
  correct 
  idea, 
  if 
  I 
  may 
  so 
  express 
  myself, 
  of 
  the 
  

   whole 
  circumference 
  of 
  the 
  plant. 
  But 
  before 
  we 
  pro- 
  

   ceed 
  to 
  dry 
  them, 
  it 
  is 
  necessary 
  to 
  separate 
  the 
  stem 
  

   from 
  the 
  pileus, 
  and 
  from 
  the 
  latter 
  to 
  scrape 
  out 
  the 
  

   fleshy 
  lamella) 
  or 
  gills, 
  if 
  an 
  Agaric, 
  or 
  the 
  tubes 
  of 
  

   ;i 
  Boletus. 
  We 
  have 
  thus 
  the 
  fungus 
  divided 
  into 
  

   five 
  portions, 
  — 
  a 
  central 
  thin 
  slice, 
  two 
  nearly 
  halves 
  of 
  

   the 
  stem, 
  and 
  the 
  same 
  sections 
  of 
  the 
  pileus. 
  These, 
  

   after 
  being 
  a 
  little 
  exposed 
  to 
  the 
  air, 
  that 
  they 
  may
