The Disintegration Machine Quote by Sir Arthur Conan Doyle

Inside was a large whitewashed room with innumerable copper wires hanging in festoons from the ceiling, and a huge magnet balanced upon a pedestal. In front of this was what looked like a prism of glass, three feet in length and about a foot in diameter. To the right of it was a chair which rested upon a platform of zinc, and which had a burnished copper cap suspended above it. Both the cap and the chair had heavy wires attached to them, and at the side was a sort of ratchet with numbered slots and a handle covered with indiarubber which lay at present in the slot marked zero. ~ The Disintegration Machine
