Abstract
It may be of interest to readers of NATURE to know that I have recently obtained unmistakable evidence of an anode dark space in the discharge in oxygen at low pressures. The anode which exhibited this remarkable phenomenon was an aluminium plate which had been used as an anode during an extended series of measurements of the Crookes dark space with kathodes of different metals. As these were continued for some months, and as the phenomenon was not noticed when the anode was fresh, one is inclined to connect the occurrence with the excessive fatigue of the metal surface.
