From wave ... or no, the event is better told than watched:
Still may the thing float free, globose and opaline
All over, save where just the amethysts combine
To blue their best, rim-round the sea-flower with a tinge
Earth's violet never knew! Well, 'neath that gem-tipped fringe,
A head lurks—of a kind—that acts as stomach too;
Then comes the emptiness which out the water blew
So big and belly-like, but, dry of water drained,
Withers away nine-tenths. Ah, but a tenth remained!
That was the creature's self: no more akin to sea,
