This page cites the book in question as a
secondary source and cites William Carpenter as the sole author. Also, if you google for "Water Not Convex",
none of the four google hits even mention Wallace. I'm sorry, but Wallace had no part in writing that book. I also find it improbable that there is anything earth-shattering (heh) in there if it only gets four google hits. True, there
could be, but it's improbable, and certainly not probable enough to just take it for granted. Remember, your own zetetic method forbids you from taking a guess and presenting it as fact.
Moreover, what Wallace has said and done outside his experiment is irrelevant. The results of his experiment speak for themselves. Even if later on he changed his mind and became a flat earther, it has no bearing on the validity of his results. The validity of the results of an experiment are independent of who conducts it. If Wallace later changed his own mind, it means nothing. Only if he
proved that there was a problem with his earlier experiment will it become relevant, and we can't know whether or not he did without a copy of the book, now, can we?
Therefore, you're going to have to find a different line of argument, Tom. It's that simple.
