were treated tenderly, and placed in a huge vasculum, and 
in it conveyed to our quarters. The zoophytes parasitic on 
Algze, brought home in the same way, made their positions 
known by exhibiting their tender and beautiful lights.” 
My friend, Mr. Hassall, has the followmg interesting re- 
marks, in the ‘ Annals of Natural History,’ and there states 
that he had ascertamed that a// the transparent zoophytes 
possess highly luminous properties. ‘This fact,” he sub- 
joins, “I first discovered in a specimen of Laomedea gela- 
tinosa, and subsequently in a great variety of other species. 
If a portion of it, adhering to the seaweed to which it is 
attached, be taken from the water and agitated, a great 
number of bright phosphorescent sparks will be emitted ; 
these sparks proceed from each of the denticles of the 
coralline containing polypi, and the phenomenon is equally 
apparent whether the specimen be in or out of water. I 
lately had an opportunity of beholding this novel and 
interesting sight of the phosphorescence of zoophytes to 
great advantage, when on board one of the Devonshire 
trawling-boats, which frequent this coast. The trawl was 
raised at midnight, and great quantities of corallines were 
entangled in the meshes of the network, all shining like 
myriads of the brightest diamonds.” A still more striking
