The Millerite prediction did not happen...

NILES' NATIONAL REGISTER, Baltimore, April 29, 1843  The back page has a report: "Millerism" which is a fine report on the Millerite prediction that the world would end on April 23.
It includes: "The eventful 23d of April, 1843 was as delightful a day as our spring has offered. True, quite an ominous discovery was made in the morning; a large quantity than ever before noticed of a substance precisely resembling sulphur had been deposited during the rain of the night before...in the evening an April shower, accompanied with thunder and lightning, refreshed the atmosphere, but the world remains yet in its orbit."
The Millerites were followers of the teachings of William Miller, who in 1831 first shared publicly his belief that the Second Advent of Jesus Christ would occur in roughly the year 1843.
An inside page has a report on the: "Death Of Commodore Porter".
