Fig. Pvessuvc in Km In fig. 5 the sparking potential is plotted against thediameter of the inner cylinder for a constant pressure of1*5 mm. of mercury. The sparking potentials for parallelplates at distances equal to those between the cylinders for to produce Discharges in Gases at Low Pressures. 485 the different diameters oi the inner cylinder, have also beenplotted (curve c).
