“We know it by analogy,” said the chairman, pompously. “All drugs increase their effect when they increase their dose; for example—for example——”

“Whisky,” said Joseph M’Connor.

“Quite so. Whisky. You see it there.”

Peter Stulpnagel smiled and shook his head.

“Your argument is not very good,” said he. “When I used to take whisky, I used to find that one glass would excite me, but that six would send me to sleep, which is just the opposite. Now, suppose that electricity were to act in just the opposite way also, what then?”

We three practical men burst out laughing. We had known that our colleague was queer, but we never had thought that he would be as queer as this.

“What then?” repeated Philip Stulpnagel.

“We’ll take our chances,” said the chairman.

“Pray consider,” said Peter, “that workmen who have touched the wires, and who have received shocks of only a few hundred volts, have died instantly. The fact is well known. And yet when a much greater force was used upon a criminal at New York, the man struggled for some little time. Do you not clearly see that the smaller dose is the more deadly?”

“I think, gentlemen, that this discussion has been carried on quite long enough,” said the chairman, rising again. “The point, I take it, has already been decided by the majority of the committee, and Duncan Warner shall be electrocuted on Tuesday by the full strength of the Los Amigos dynamos. Is it not so?”
