First appearance of the paper in which Grove describes his discovery of striae, the dark bands that occur in electrical breakdown.

"Grove was the first to study what became known as "sputtering" although others had observed the effect while studying glow discharges. Grove used a tip of wire as the coating source and sputtered a deposit onto a highly polished silver surface held close to the wire at a pressure of about 0.5 Torr. He noted a coating on the silver surface when it was made the anode and the wire the cathode of an electrical circuit.(History of PVD Coatings).
