Nice find!  Congratulations!  How to identify them?  By the nice
purple glow... just don't look at it very long.  More seriously, you
will probably see what looks like liqiud silver spattered around on
the inside of the glass if it's a mercury vapour tube.

Being mad, yes---that's fun; being a mad hatter, that, most likely,
wouldn't be as much fun.
