Here is all the invisible world, caught, defined, and calculated. In these books the Devil stands stripped of all his brute disguises. Here are all your familiar spirits-your incur and succubi; your witches that go by land, by air, and by sea; your wizards of the night and of the day. Have no fear now-we shall find him out, and I mean to crush him utterly if he has shown his face!
