witness of Davidson's seizure, and so it falls naturally to
me to put the story upon paper.

When I say that I was the immediate witness of his seizure, I mean
that I was the first on the scene. The thing happened at the Harlow
Technical College, just beyond the Highgate Archway. He was alone in
the larger laboratory when the thing happened. I was in a smaller
room, where the balances are, writing up some notes. The thunderstorm
had completely upset my work, of course. It was just after one of the
louder peals that I thought I heard some glass smash in the other
room. I stopped writing, and turned round to listen. For a moment
I heard nothing; the hail was playing the devil's tattoo on the
corrugated zinc of the roof. Then came another sound, a smash--no
doubt of it this time. Something heavy had been knocked off the bench.
I jumped up at once and went and opened the door leading into the big
laboratory.

I was surprised to hear a queer sort of laugh, and saw Davidson
standing unsteadily in the middle of the room, with a dazzled look on
his face. My first impression was that he was drunk. He did not notice

"Davidson!" cried I. "What's the matter with you?" He turned round in
my direction and looked about for me. He looked over me and at me
and on either side of me, without the slightest sign of seeing me.
"Waves," he said; "and a remarkably neat schooner. I'd swear that was
Bellows' voice. _Hullo_!" He shouted suddenly at the top of his voice.

I thought he was up to some foolery. Then I saw littered about his
feet the shattered remains of the best of our electrometers. "What's
up, man?" said I. "You've smashed the electrometer!"

"Bellows again!" said he. "Friends left, if my hands are gone.
Something about electrometers. Which way _are_ you, Bellows?" He
suddenly came staggering towards me. "The damned stuff cuts like
butter," he said. He walked straight into the bench and recoiled.
"None so buttery that!" he said, and stood swaying.

I felt scared. "Davidson," said I, "what o
