From DR. BOLI’S ALPHABET OF OCCUPATIONS.

X for the Xylotomist, whose specialized profession
Is cutting bits of wood to fit into a microscope.
It’s more than just a job, she worries—now it’s an obsession.
She thinks she has become, she tells us, holding back her tears,
A xylotomic addict—maybe even worse, she fears—
And now, she says, to go cold turkey is her only hope.
But then who’ll cut our bits of wood to fit our microscope?
