Sept. 11th, 1847. — ^Ir. Hyndman dredged a few specimens on Zoo- 

 phytes from 20 fathoms at entrance of Belfast Bay (bottom shelly sand). 

 They gave, on being disturbed, and then only, a succession of sparks

 tremely brittle), each portion continued to give out the light, in the same 

 manner as the entire animal.
