IGG 
PROFESSOR OLIVER LODGE ON ETHER AND MATTER. 
There was not a wink when the sparks occurred, whatever the speed. The test 
for electrification 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 Avas 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.
