Upon my word, you really deserve--Since Mr George Combe has clearly shown in his admirable work "On the Constitution of Man, and its adaptation to the world around him," that ignorance is a statutable crime before Nature, and punishable, and punished by the laws of Providence,--you deserve, I say, unless you contrive to make Mr H. your substitute, which I think would be just, yourself to be the subject of the nocturnal visit of a vampyr. Your scepticism will abate pretty considerably, when you see him stealthily entering your room, yet are powerless under the fascination of his fixed and leaden eye--when you are conscious, as you lie motionless with terror, of his nearer and nearer approach,--when you feel his face, fresh with the smell of the grave, bent over your throat, while his keen teeth make a fine incision in your jugular, preparatively to his commencing his plain, but nutritive repast. You would look a little paler the next morning, but that would be all for the moment; for Fischer informs us, that the bite of a vampyr leaves in general no mark upon the person. But he fearfully adds, "it (the bite) is nevertheless speedily fatal, unless the bitten person protect himself by eating some of the earth from the grave of the vampyr, and smearing himself with his blood." Unfortunately, indeed, these measures are only of temporary use. Fischer adds, "if through these precautions the life of the victim be prolonged for a period, sooner or later he ends with becoming a vampyr himself; that is to say, he dies, and is buried, but continues to lead a vampyr life in the grave, nourishing himself by infecting others, and promiscuously propagating vampyrism." Now this is no romancer's dream. It is a succinct account of a superstition, which to this day survives in the east of Europe, where little more than a century ago it was frightfully prevalent. At that epoch, vampyrism spread like, an epidemic pestilence through Servia and Wallachia, causing innumerable deaths, and disturbing all the land with apprehension of the mysterious visitation, against which no one felt his life secure. This is something like a good solid practical popular delusion. Do I believe it?--to be sure I do; the facts are matter of history. The people died like sheep, and the cause and method of their dying was, in their belief, what has just been stated. You suppose, then, they died, frightened out of their lives; as men have died, whose pardon has been proclaimed when their necks were already on the block, of the belief that they were going to die? Well, if that were all, the subject would be worth examining; but there is more in it than that, as the following o'er true tale will convince you, the essential parts of which are attested by perfect documentary evidence.
