Humphry Osmond first proposed the term "psychedelic" at a meeting of the New York Academy of Sciences in 1956. He said the word meant "mind manifesting" (from "mind", ψυχή (psyche), and "manifest", δήλος (delos)) and called it "clear, euphonious and uncontaminated by other associations." Huxley had sent Osmond a rhyme containing his own suggested invented word: "To make this trivial world sublime, take half a gram of phanerothyme" (θυμός (thymos) meaning 'spiritedness' in Ancient Greek.) Osmond countered with "To fathom Hell or soar angelic, just take a pinch of psychedelic" (Alternative version: To fall in Hell or soar angelic / You'll need a pinch of psychedelic.).
