Note 5 — Chapter II
Reading edition
On a dark night the light could be seen at about two hundred paces distant. It is remarkable that in all the glowworms, shining elaters, and various marine animals, which I have observed (such as the crustacea, medusæ, nereidæ, a coralline of the genus Clytia, and Pyrosoma), the light has been of a well-marked green colour.
