Which author created the word 'runcible'?

"Runcible" is a nonsense word invented by Edward Lear. The word appears (as an adjective) several times in his works, most famously as the "runcible spoon" used by the Owl and the Pussycat. The word "runcible" was apparently one of Lear's favourite inventions, appearing in several of his works in reference to a number of different objects. In his verse self-portrait, The Self-Portrait of the Laureate of Nonsense, it is noted that "he weareth a runcible hat". Other poems include mention of a "runcible cat", a "runcible goose" (in the sense of "silly person"), and a "runcible wall".
