Thanks! I read about that when it happened, which influenced my decision to use Origin of Species here. However, as it was a rebuttal attached, and not attributed to Darwin, and didn't distort or mutilate Darwin's own work, it didn't seem to fit the scenario.
Something very similar to this exists: A version of Origin of Species with a 50-page rebuttal attached: https://www.google.com/search?q=creationist+origin+of+specie...
