  Amos's description of the technique will be very useful
  for those without access to journals or libraries.

  BUT (and I don't often shout) why is this called the
  alcian yellow method when the bacteria are stained by
  toluidine blue?  This seems equivalent to the "eosin
  method for nuclei," or the "alum-hematoxylin method for
  cytoplasm and collagen."
