This barbed structure of the hairs is chiefly seen towards their attenuated extremities. And now do you ask—"What is the object of this elaborate contrivance, or rather series of contrivances ?

You have seen that the animal has no power of pursuing prey : he is im- movably fixed to the walls of his castle which is im- movably fixed to the solid rock. He is compelled therefore to subsist on what passes his castle, and on what he can catch as he sits in his doorway and casts his net at random.
