In this Series Deleuze plugs Alice's Adventures in Wonderland, and Through the Looking Glass into the three orientations of the dynamic genesis: the depths, the heights, and the surface. He mentions the circular mushroom that causes Alice to grow or to shrink depending upon which side she eats from. This circles the reader back to the very beginning of The Logic of Sense as that's how the book starts.In a footnote, Deleuze mentions two poems by Carroll that illustrate the good voice on high. They are: The Two Brothers and The Three Voices He also mentions Sylvie and Bruno which he again calls a masterpiece as he did earlier in the book. It gives another example of the good voice on high withdrawn but also the two surfaces, the surface between bodies and ideas (ordinary reality in Sylvie and Bruno), and the metaphysical surface (the fairy/magic reality). The first book is here. Sylvie and Bruno Concluded is here. About two thirds of the way through this Series there's an inflexion point where Deleuze stops talking about Alice and Lewis Carroll and begins to look at great authors as Doctors or Diagnosticians of Civilization. He'll talk about this in relation to the pure event and the metaphysical surface. The Series ends with obscure quotes from another Lewis Carroll story: A Photographer's Day Out. I don't find it in print on the internet but here's a video of the story being read.
