A few brownspots to margins of plate. Fine and clean. First printing of one of the main papers relating to the determination of the standard electrical unit, the relations between the ohm, the unit of resistance and the electromagnetic unit of resistance."It is a tribute to Rayleigh's great experimental care that his final results have not been appreciably altered by more modern work. He appeared to possess the uncanny power to make the simplest of equipment produce the utmost precision."(Robert Bruce Lindsay).
