Isinglass Substance

But what I am driving at here is this. That same infinitely thin, isinglass substance, which, I admit, invests the entire body of the whale, is not so much to be regarded as the skin of the creature, as the skin of the skin, so to speak; for it were simply ridiculous to say, that the proper skin of the tremendous whale is thinner and more tender than the skin of a new-born child. But no more of this.
