Light of Glow-worms

Abstract

THE letter by Dr. Ramdas and Dr. Venkiteshwaran¹ on the “Spectrum of Glow-worm” will surely arouse interest in the fascinating subject of animal luminescence and stimulate photophysical research on the phenomenon. The writers note that their worm glowed only by night, could be stimulated by shaking, and that the light was apparently under voluntary control. These details I am able to supplement by other observations, which may be of value to research workers who wish to take up the subject.
