There have, of course, been numerous articles treating the theme of identity and other related themes in PUDD'NHEAD WILSON. One minor piece that I wrote some time ago, "Pudd'nhead Wilson: A Search for Identity," (Mark Twain Journal (Summmer 1977), pp. 1-6, bears directly on your question. Frederick Anderson's Introduction to a facsimilie edition of PW (San Francisco: Chandler Publishing Co., 1968) also treats this question in considerable depth. And there are many, many more excellen;t treatments. Joe McCullough
