Wonderful or supernatural events are not so uncommon, rather they are irregular in their incidence. Thus there may be not one marvel to speak of in a century and then often enough comes a plentiful crop of them; monsters of all sorts swarm suddenly upon the earth, comets blaze in the sky, eclipses frighten nature, meteors fall in rain, while mermaids and sirens beguile and sea-serpents engulf every passing ship and terrible cataclysms beset humanity. But the strange event which I shall here relate came alone, unsupported, without companions into a hostile world and for that very reason claimed little of the general attention of mankind. For the sudden changing of Mrs. Tebrick into a vixen is an established fact which we may attempt to account for as we will. Certainly it is in the explanation of the fact and the reconciling of it with our general notions that we shall find most difficulty and not in accepting for true a story which is so fully proved and that not by one witness but by a dozen, all respectable and with no possibility of collusion between them. . . .
