Cornelius, David William, 1883- · leaf 32
ric potassium metal C, The photo-elec-tric metal was distilled upon an iron disk at the position B. Totransfer this disk into the final position C, the top of the cylin-der is made of iron so that the cylinder may be raised or loweredby means of a magnet. The cylirder is emitted from the cell… … FTC. VI.
