SEAS OF FLAME. 85 



Not the least woiiderful feature of this animal is the variety 

 of tints; white, green, various shades of deep red, orange 

 green, and azure blue having been ascribed to it by different 

 observers, — a fact that must stamp it as the most wonderful 

 of all light-givers, a veritable living diamond. 



One of the most remarkable exhibitions of phosphorescence 

 was observed in January, 1880, by Commander R. E. Harris 

 of the steamship " Shahjehan," — a display so unusual that 

 I quote Capt. Harris's letter in full ; and, while he is in- 

 clined to consider the exhibition as possibly electric, it would 

 seem that the luminous objects referred to were phosphores-

 connection with the phenomenon. 



" The most remarkable phenomenon," says Capt. Harris, " that 

 I have ever seen at sea was seen by myself and officers on the 

 5th instant, between Oyster Reef and Pigeon Islands (Malabar 

 coast) . At -ten p.m. we were steaming along very comfortably. 

 There was a perfect calm, the water was without a ripple upon it, 

 the sky was cloudless, and, there being no moon, the stars shone

 was one of great quietude. At the above-named hour I went on 

 deck, and at once observed a streak of white matter on the 

 horizon bearing south-south-west. I then went on the bridge, 

 and drew the third officer's attention to it. In a few minutes it 

 had assumed the shape of a segment of a circle, measuring about 

 forty-five degrees in length, and several degrees in altitude about 

 its centre. At this time it shone with a pecuHar but beautiful 

 milky whiteness, and resembled (only in a huge mass, and greater 

 luminous intensity) the nebulce sometimes seen in the heavens. 

 "We were steaming to the southward ; and, as the banli of light 

 extended, one of its arms crossed our path. The whole thing
