In "Rare Maps For Collectors" in the November Word Ways, I presented a mapping between integers and letters for producing "perfect" German number names. However, Hans Havermann in Colloquy has questioned my German spelling. He is right to do so; I have confused German und with Dutch en, to produce nonsensical bilingual compounds such as einenzwanzig instead of einundzwanzig.
