Jim Finn, the noted biologist, was stumped. He'd spent
months studying the little green frogs in the Keefo swamp.
The population, despite all efforts at predator control, was
declining at an alarming rate. Finally Finn went to the
chemistry department at his college, to see if anyone there
might be able to help. Tom Trom looked into the problem,
and came up with a solution. The little frogs had succumbed
to a chemical change in the swamp's water, and simply
couldn't stay coupled long enough to reproduce. Trom
brewed up a new adhesive, made from a dash of this, a zoss
of that, and, most critically, one part of sodium. "You
mean?..." Jim said when told. "Yes," said Tom. "They
needed mono-sodium glue to mate."
