Shortly after the Order of the Dolphin meeting, Lilly began incorporating ketamine and LSD (legal at the time) into his experiments, hoping it would help him communicate better with dolphins. A well-known historical example of a dolphin in heraldry, was the arms for the former province of the Dauphiné in southern France, from which were derived the arms and the title of the Dauphin of France, the heir to the former throne of France (the title literally means "The Dolphin of France").
