Often people separate the first half of that, though.

Chapter IV, titled, "In Which Our Protagonist Meets A Dashing Strange." is how I imagine many read that, especially when Chapter IV is in big letters, or even without the word "Chapter", like a title, with the rest of it in what would be recognized as a subtitle.

"In which (something happens)" was a common form when chapter titles were descriptions of the events in it, so it's fair to assume it was meant to refer to the chapter itself.

Later works often lampooned and subverted those tropes, of course.

That makes more sense. I mean this is kind of a long chapter title, otherwise:

>Oliver Becomes Better Acquainted with the Characters of His New Associates; and Purchases Experience at a High Price. Being a Short, but Very Important Chapter, in this History

That said I always kinda loved that way of writing.
