This lump continued to increase in size until it appeared like a bunch of crab's legs; and, indeed, such it proved in a very few minutes to be; for the points of the toes were at length extricated from this hole in its back, the legs spread out, the body followed, and the crab walked away quite entire, even to the points of its nipper-claws, leaving a perfectly entire shell behind it, so that, when we looked, it seemed as though there were two complete crabs instead of one!
