The one glimpse he had had of the title was enough to send him into transports, and some of the diagrams set in the vague Latin text excited the tensest and most disquieting recollections in his brain.

It was when he regained his senses that he told his story; told his fantastic figment of madness in frantic whispers, lest his friend be not quick to burn the accursed book and give wide scattering to its ashes.
