I think my quote from James still stands head and shoulders above those two examples.

We're talking 932 characters, 165 words. George Eliot was positively monosyllabic in comparison.

This is actually on-topic, because I used Lingua::EN::Sentence to parse the whole Gutenberg Edition of James' "The Golden Bowl" to find the longest sentence.

I would happily re-write it in mock-Perl syntax, but after many readings, I still don't actually know where the clauses begin and end, let along what it actually means...
