Those which helped to make this bit of stone are called coral-insects: but they are not really insects, and are no more like insects than you are. Coral-polypes is the best name for them, because they have arms round their mouths, something like a cuttlefish, which the ancients called Polypus. But the animal which you have seen likest to most of them is a sea-anemone.
"Hullo, you boys!" sang out the Captain on catching sight of them, after consulting his watch; "you'll have to come out of that at once. Time's up, for the steamer will be due in another five minutes. Look sharp!" "Do stop a moment," answered Bob, just then busy at the base of a rock close by the pier, which was nearly awash with the incoming tide, "I've found such a jolly sea-anemone here.
My labours failed to make me a zoologist, and the multitude of my designs and my descriptions have left me helplessly ignorant of the anatomy of a sea-anemone. Yet I cannot look upon the mental discipline as useless. It taught me to concentrate my attention, to define the nature of distinctions, to see accurately, and to name what I saw.
Now Corals possess, in an extraordinary degree, the power of assimilating to themselves the lime contained in the salt water around them; and as soon as our little Coral is established on a firm foundation, a lime deposit begins to form in all the walls of its body, so that its base, its partitions, and its outer wall, which in the Sea-Anemone remain always soft, become perfectly solid in the Polyp Coral and form a frame as hard as bone.
The lady on his right, whom he had brought in, was a leading actress of the town indeed, of the United Kingdom and America, for that matter a creature in airy clothing, translucent, like a balsam or sea-anemone, without shadows, and in movement as responsive as some highly lubricated, many-wired machine, which, if one presses a particular spring, flies open and reveals its works.
Is it probable, then, even a priori, that if life or anything like it exists on any other planet, it would exist in forms at all as near our own as a buttercup is to a human being, or a sea-anemone is to a cat or a pine-tree?" "Well, it doesn't look likely, now you come to put it so," Frida answered thoughtfully: for, though English, she was not wholly impervious to logic. "Likely?
Such are the hydra, the polyp, the coral, and the sea-anemone. When we look to the common structure of these animals, to find the ancestral type, we must ignore the nerve and muscle-cells which they have developed in some degree. Fundamentally, their body consists of a pouch, with an open mouth, the sides of the pouch consisting of a double layer of cells.
"Ortie de mer," or "sea-nettle," is, in fact, the French appellation for our "sea-anemone," a creature with which everybody, since the great aquarium mania, must have become familiar, even to the limits of boredom.
Thus he learned to beware of the graceful jelly-fishes who were constantly to be met floating about, their long tentacles streaming behind, and their umbrella-shaped disks expanding and contracting as they swam, for he knew that the Jelly-Fish was a cousin of the Sea-Anemone, and that its tentacles could sting most unpleasantly.
He was a town man, and she an artless islander, yet he had opened himself out, like a sea-anemone, without disturbing the epiderm of her nature. It was monstrous that a maiden who had assumed the personality of her of his tenderest memory should be so impervious. Perhaps it was he who was wanting. Avice might be Passion masking as Indifference, because he was so many years older in outward show.
