Closing the lecture of Friday 27 October 1967, Neville told the room the schedule: "We'll be here on Monday, as you know, every Monday and Friday until the middle of December. But, what I will speak on Monday, I haven't the slightest idea. I only know that I'll be here...and you'll be well fed." The corpus bears the announcement out at every meeting - fifteen consecutive Monday and Friday lectures run from that evening through Friday 15 December 1967 without a single gap, after which the series stops.
