This world: Of the nature of Flatland -- Of the climate and houses in Flatland -- Concerning the inhabitants of Flatland -- Concerning the women -- Of our methods of recognizing one another -- Of recognition by sight -- Concerning irregular figures -- Of the ancient practice of painting -- Of the universal colour bill -- Of the suppression of the chromatic sedition -- Concerning our priests -- Of the doctrine of our priests -- Other worlds: How I had a vision of Lineland -- How I vainly tried to explain the nature of Flatland -- Concerning a stranger from Spaceland -- How the stranger vainly endeavoured to reveal to me in words the mysteries of Spaceland -- How the sphere, having in vain tried words, resorted to deeds -- How I came to Spaceland, and what I saw there -- How, though the sphere shewed me other mysteries of Spaceland, I still desired more; and what came of it -- How the sphere encouraged me in a vision -- How I tried to teach the theory of three dimensions to my grandson, and with what success -- How I then tried to diffuse the theory of three dimensions by other means, and of the result.
