Tins IS the NOCTILUCA, a tiny being, about as large as the head of a minikin pin, which s\aims in our seas, and is remarkable for its phosphorescent power. If a vessel be h led with sea-water and brought into a dark room, the Noctiluca fills it with little paiUets ot bluish light, which shine for an instant like stars in the firmament, and W n l^v, t- 'If li' *.i ^T «»t t'l^''- momentary radiance by tapping the vessel, or even by a heavy tootfall on the floor of the room. j i-i b Each of these little beings is furnished with a minute tail-like appendage, by means of iiicli It IS enabled to proceed through the water; and on certain favourable occasions iiey nil he sea with their luminous hosts, and cause each wave to become a breakin- mass ot liquid fire.
