Needless to say, as a Poe fan, I've read (and greatly liked) "The Premature Burial." Poe took quite an interest in this motif; it crops up in some of his other stories, too, such as "The Fall of the House of Usher" and "Berniece."

Thanks, Werner. I can always depend on you for a stunning comment.

Thanks, Paula! (Now I'm blushing.... :-) )
