Through the Looking-Glass, and What Alice Found There (1872) is a novel by Lewis Carroll (Charles Lutwidge Dodgson), the sequel to Alice's Adventures in Wonderland (1865). Set some six months later than the earlier book, Alice again enters a fantastical world, this time by climbing through a mirror into the world that she can see beyond it. Through the Looking-Glass includes such celebrated verses as 'Jabberwocky' and 'The Walrus and the Carpenter', and the episode involving Tweedledum and Tweedledee. The mirror which inspired Carroll remains displayed in Charlton Kings.

Menthol cigarettes are constructed similarly to non-mentholated cigarettes, with menthol added at any of several stages during the manufacturing process. Menthol may be derived from distilled corn mint oil, or produced synthetically. While trace amounts of menthol may be added to non-mentholated cigarettes for flavor or other reasons, a menthol cigarette typically has at least 0.3% menthol content by weight. Lower-tar menthol cigarettes may have menthol levels up to 2%, in order to keep menthol delivery constant despite the filtration and ventilation designs used to reduce tar.
