This chapter from Logic of Sense by Gilles Deleuze categorizes different dualities of series using examples from Sylvie and Bruno by Lewis Carroll. Looks at esoteric words that make connections or runs through between series. The word snark from Carroll's The Hunting of the Snark represents the blank word that circulates between the series of consumptions (bodies) and the series of propositions, or the series of denotations and expressions. Examines portmanteau words and their relationship with the disjunctive synthesis. References Finnegans Wake by James Joyce.
