Goddammit. I was all excited to have this great collection, I read a few pages into Twenty Thousand Leagues... having never read any Verne before, only to do a little research and realize that these are apparently the best-known English translations: in other words, the shitty ones that cut out large chunks for no good reason and make mistakes that lead generations of English-speaking readers to think that Verne was an amateurish writer for young children.
Now I have to go find a good translation. Grumble grumble.
