It was, then, about twenty minutes to ten on the night of the fourth of June, eighteen hundred and eighty-six, that, after disposing of a pint of beer and a Welsh rarebit for my supper, I seated myself in my arm-chair, cocked my feet upon a stool, and lit my pipe, as was my custom. Both my pulse and my temperature were, as far as I know, normal at the time. I would give the state of the barometer, but that unlucky instrument had experienced an unprecedented fall of forty-two inches—from a nail to the ground—and was not in a reliable condition. We live in a scientific age, and I flatter myself that I move with the times.
