"The World will end on 28 February"

Fri 7 Jan 1763. I desired George Bell, with two or three of his friends, to meet me with one or two others. We took much pains to convince him of his mistakes, particularly that which he had lately adopted, ‘that the end of the world was to be on February the 28th’, which at first he had earnestly withstood. But we could make no impression upon him at all. He was as unmoved as a rock.
