virulence of these organs has been abundantly proved by many natu- 
ralists, myself among the number, and Mr. Bennett to his cost, aS 
already narrated. We can only suppose that the injection of the 
poison is under the control of the Physalia’s will, and the impunity °^' 
the bold little fishes is sufficiently accounted for.” 
Among the Physalia captured on our coast, one was obtained at 
Tenby, by Mr. Hughes, who has given a report of the capture, in which 
he mentions a circumstance as “normal,” which excited Mr. Grosse 8 
curiosity ; it was said to be accompanied by “ its attendant satellites, 
two VUeHas. In reply to his inquiries, Mr. Hughes says, “ My autho-

fringes furnished with vibratile cilia, which are swimming orga JlS- 
Moreover, as these vibratile fringes are inserted directly over the p rlir 
cipal canal, in which the nourishing fluid circulates, they ought nec® 8 ^

The class may be divided into three orders or families, naxn e ^’ 
Beroe, Callianirea, and Cestea. 
The creatures belonging to these three orders swarm in the de®P 
sea ; they often appear quite suddenly, and in vast numbers, in cert® 111 
localities.
