It's at the very bottom. To save you the time, here's what it says:
*** Update! To answer ... yes, I do remember the passing reference to the courageous black balloonist in the polar sections of the the second series. I thought it might have something to do with this, and that's the Benefit of the Doubt position I was taking during the discussions. To save you time from reading it, all of the black people in that book are ignorant, violent and worship trinkets. (It's been a looong while since I've read it, so I'm being vague out of sketchy memory.) Since Moore was already using Verne via Nemo, and since he was doing other correctives (for lack of a better term) with other era attitudes and characters throughout the LoEG, I wondered if perhaps he was doing the same here, just really low-key about it. Ha. There I was being all clever thinking I'd spotted a subtle reference to the work that came before the one everybody knows (the one where, despite what the movie shows, they don't use a balloon), and down the road I'd be proven right! What an idiot I turned out to be.
And with that, done. Completely.
