While digging though some old journals in a fruitless side-quest, I came across this delightful description of what I think is the Comet Encke.
It is quite an astonishing prediction, and the last line is perfection.
In 1926, several journals and almanacs syndicated a column discussing this comet. The above is from The New Jerusalem magazine and theological inspector which has added "This is very alarming!".
Most of the other reprints leave off this last line - but The Christian Advocate" adds "But who expects that the earth will endure four millions of years!"
Only a few thousand more years until we will know if the prediction was accurate!
