  Thanks P. Emry for your loud shout for histo-literacy!
  We need more like you!

  As you know full well, there isn't a compound called xylol. That
  execrable and meaningless word crept into histo-speak about 100
  years ago, along with several other pseudo-chemical names of
  organic solvents.

  The correct designation is XYLENES (mixed isomers). This is a liquid
  miscible with absolute alcohol and with melted paraffin wax. Xylenes
  are also miscible with traditional resinous mounting media.
