Bunsen Burner

Doctor Bunsen, of burner fame
Enjoyed his elements
Of all of them
Beryllium
Was his mostest favorite.

One day a fly flew in his prep
And upon his proboscis
His sample dear
A portion there
Flew away from thence.

He chased the bug around the lab
Until he had the thief
And crushed the flea
Most carefully
His science could not be beat.

He laid it in a crucible
And burned it into ash
Recovering
Most lovingly
One-tenth a milligram!
