- I'm Tweedledee, he's Tweedledum.
- We're spacemen marching to and from.
- We slythe among the mimsy troves,
- And tire among the borogroves. (TOS: "Plato's Stepchildren")
By the 24th century, the novel was known to at least some extent on Bajor, since Kira Nerys used it a metaphor for the mirror universe upon returning from there in 2370. (DS9: "Crossover") In 2371, Smiley O'Brien used a similar metaphor to describe the journey to the mirror universe to Benjamin Sisko, suggesting that Carroll's novel existed in that universe as well, and that knowledge of it somehow survived the fall of the Terran Empire.
