  It 
  would 
  

   be 
  interesting 
  to 
  determine 
  whether 
  the 
  smell 
  is 
  due 
  to 
  a 
  

   special 
  secretion, 
  to 
  the 
  dung 
  frequented 
  by 
  the 
  beetle, 
  or 
  

   to 
  the 
  dung 
  acted 
  on 
  in 
  the 
  body 
  so 
  as 
  to 
  become 
  more

  that 
  these
