Din dicționarul THE DEVIL'S DICTIONARY ((C)1911 Released April 15 1993) :

  MOLECULE, n.  The ultimate, indivisible unit of matter.  It is
  distinguished from the corpuscle, also the ultimate, indivisible unit
  of matter, by a closer resemblance to the atom, also the ultimate,
  indivisible unit of matter.  Three great scientific theories of the
  structure of the universe are the molecular, the corpuscular and the
  atomic.  A fourth affirms, with Haeckel, the condensation of
  precipitation of matter from ether -- whose existence is proved by the
  condensation of precipitation.  The present trend of scientific
  thought is toward the theory of ions.  The ion differs from the
  molecule, the corpuscle and the atom in that it is an ion.  A fifth
  theory is held by idiots, but it is doubtful if they know any more
  about the matter than the others.
