How would you setup a model in Rails to reference the same model type?

Let's say I have a model for a thing called "Chapter". I want to be able to reference the next chapter and the previous chapter for each chapter. How would you go about setting this up?

So what I'm looking for is something like this:

c = Chapter.first
c.next_chapter

c.next_chapter should return a chapter object that is the next chapter.
