“Light From Potatoes”

The emission of light from the common potato, when in a state of decomposition, is sometimes very striking. Dr. Phipson, in his work on ‘Phosphorescence,’ mentions a case in which the light thus emitted from a cellarful of these vegetables was so strong as to lead an officer on guard at Strasbourg to believe that the barracks were on fire.
