There was not a wink when the sparks occurred, whatever the speed. The test for electricification effect is easy, because the charge can be switched on and off while in a state of steady spin, and the slightest difference would be observed. There is certainly no perceptible effect.
When the disks were slowed down and nearly stopped, there was the old temporary flickering of the bands, but this had nothing to do with electrification, it was merely irregular warmth in the air.
We tried also a couple of Leyden jars with their outer coats connected to the disks, so as to get strong "B" sparks between them (see 'Proc. Roy. Soc.,' 1892, vol. 50, pp. 4 and 18), but still there was no effect.
Without further delay I conclude that neither an electric nor a magnetic transverse field confers viscosity upon the ether, nor enables moving matter to grip and move it rotationally.
