Thanks. I'm going to have to see if I can track down a copy of that.
In connection with the Norman belief, I quote the following:
"It is an opinion which prevails much in Germany, that there are corpses which chew in their graves, and devour whatever lies near them. Some go so far as to say, they may be heard munching, like hogs, with a sort of grunting, grumbling noise.
"A German writer, named Michael Raufft, has writ a treatise upon this subject, which he entitles, De Masticatione mortuorum in tumulis. He supposes it to be a certain fact, that dead corpses have devoured their linnen, and whatever else was within reach of their mouths, and that some have even eat their own flesh from their bones. He observes that it is a custom in some parts of Germany to prevent this practice by putting a lump of earth under the chin of the corpse, and that in other places they make use of a piece of money, or a stone, for this purpose, or tie the throat close with a handkerchief. He quotes several German authors that mention this ridiculous custom, and makes extracts from several others, who speak of corpses that have devoured their own flesh in the grave. This work was printed at Leipsick in 1728; and the author frequently refers to another writer, named Philip Rehrius, who published a treatise in 1679, with the same title, De Masticatione mortuorum. To the facts he has collected, he might have added the story of Henry Count of Salm, who, being thought dead, was really buried alive. The night after, a great cry was heard in the church of the abbey of Haute-Seille, where he was buried; and his grave being opened the next morning, he was found with his face downwards, instead of lying upon his back, as he had been buried.
"A few years since, a man being buried in the churchyard at Bar-le-duc, there was a noise heard in the grave; and the next day the man, being dug up, was found to have eat the flesh off his arms. This I had from several eye-witnesses. The man, it seems, was stupefied by drinking a great quantity of brandy, and was taken for dead. Raufft mentions a woman of Bohemia, in the year 1345, who devoured half of her burying-linnen. In Luther's time, there was a man and woman, that eat their own bowels in their graves; and in Moravia, a man devoured the linnen belonging to a woman that lay in the next grave."
This is from the Dissertation upon the Apparitions of Angels, Daemons, and Ghosts, and Concerning the Vampires of Hungary, Bohemia, Moravia, and Silesia, by the Reverend Father Dom Augustin Calmet, a Benedictine Monk, and Abbot of Senones in Lorraine, as cited by William Scott Home in his article on "The Lovecraft 'Books': Some Addenda and Corrigenda". I've heard something similar several years ago in a documentary on premature burial; apparently it's a fairly widespread belief, or was (may still be, in some areas, for all I know).
