the oral disc. On one margin of the disc the rent involved the base of one 
of the outer row of tentacles, and extended along it. I was much interested 
in watching its progress along the tentacle, as it seemed doubtful whether it 
would tear along its whole length, or detach one or other half from its 
attachment to the body. The strain seemed great on the parts, and at last 
the lower half tore off from its base, and, immediately closing into a perfect 
tube, hung as a branch from its parent trunk. The wound in this, too, 
seemed to close at once when the strain was taken off. I have mentioned 
this apparently trivial detail as it may explain the occasional occurrence of 
the double or branched tentacle which has been observed in Anthea cereus. 
At 5.45, less than three hours from the commencement of the process, the 
division was complete, the upper half falling to the bottom of the vessel. At 
6.5 the lower followed it, and the two new individuals lay together almost 
motionless.”
