Frog Population
Animals have these advantages over man:  they never hear the clock strike, they die without any idea of death, they have no theologians to instruct them, their last moments are not disturbed by unwelcome and unpleasant ceremonies, their funerals cost them nothing, and no one starts lawsuits over their wills. 
~Voltaire, letter to Count Schomberg, 31 August 1769
Frogs never drink. They absorb water from their surroundings by osmosis.
A noted biologist, who had been studying little green frogs in a swamp, was stumped. The frog population, despite efforts at predator control, was declining at an alarming rate.

A chemist at a nearby college came up with a solution: The frogs, due to a chemical change in the swamp water, simply couldn't stay coupled long enough to reproduce successfully. The chemist then brewed up a new adhesive to assist the frogs' togetherness, which included one part sodium.

It seems the little green frogs needed some monosodium glue to mate.
