|-M. J. Shields*|
*I had attributed this to Mark Twain (don't recall why), when i received this letter (from Marnen Laibow-Koser - Thanks!):
I did, however, come across one error: the "Plan for the Improvement of English Spelling" that you attribute to Mark Twain is actually (IIRC) a few paragraphs out of a letter to *The Economist*, written by one M.J. Shields (or M.J. Yilz, by the end of the letter). The letter is quoted in full in one of Willard Espy's *Words at Play* books, as well as in other places (I believe it's in Giles Brandreth's *The Joy of Lex*).
