MY DEAR MR. LANGDON, I do not wonder that you find no answer from your country friends to the curious questions you put. They belong to that middle region between science and poetry which sensible men, as they are called, are very shy of meddling with. Some people think that truth and gold are always to be washed for; but the wiser sort are of opinion, that, unless there are so many grains to the peck of sand or nonsense respectively, it does not pay to wash for either, so long as one can find anything else to do. I don't doubt there is some truth in the phenomena of animal magnetism, for instance; but when you ask me to cradle for it, I tell you that the hysteric girls cheat so, and the professionals are such a set of pickpockets, that I can do something better than hunt for the grains of truth among their tricks and lies. Do you remember what I used to say in my lectures?--or were you asleep just then, or cutting your initials on the rail? (You see I can ask questions, my young friend.) Leverage is everything,--was what I used to say;--don't begin to pry till you have got the long arm on your side. To please you, and satisfy your doubts as far as possible, I have looked into the old books,--into Schenckius and Turner and Kenelm. Digby and the rest, where I have found plenty of curious stories which you must take for what they are worth. Your first question I can answer in the affirmative upon pretty good authority. Mizaldus tells, in his “Memorabilia,” the well-known story of the girl fed on poisons, who was sent by the king of the Indies to Alexander the Great. “When Aristotle saw her eyes sparkling and snapping like those of serpents, he said, 'Look out for yourself, Alexander! this is a dangerous companion for you!'”--and sure enough, the young lady proved to be a very unsafe person to her friends. Cardanus gets a story from Avicenna, of a certain man bit by a serpent, who recovered of his bite, the snake dying therefrom. This man afterwards had a daughter whom venomous serpents could not harm, though she had a fatal power over them. I suppose you may remember the statements of old authors about Zycanthropy, the disease in which men took on the nature and aspect of wolves. Actius and Paulus, both men of authority, describe it. Altomaris gives a horrid case; and Fincelius mentions one occurring as late as 1541, the subject of which was captured, still insisting that he was a wolf, only that the hair of his hide was turned in! Versipelles, it may be remembered, was the Latin name for these “were-wolves.” As for the cases where rabid persons have barked and bit like dogs, there are plenty of such on record. More singular, or at least more rare, is the account given by Andreas Baccius, of a man who was struck in the hand by a cock, with his beak, and who died on the third day thereafter, looking for all the world like a fighting-cock, to the great horror of the spectators.
