opened the door and started a new current of air in the room.
It seems that any motion about the room by myself may affect
its action, tho this is not absolutely uniform.
Later in the evening I tried the experiment again with both
hands and no motions occurred worthy of notice. Then I tried
the left hand alone and after a wait of perhaps three or four
minutes the cylinder began to rotate from left to right for three
revolutions rather rapidly and then suddenly stopped, paused and
reversed the rotation, going half a revolution and then again
reversed it and went three quarters of a revolution and stopped
and would move no 'more. I then tried with the right hand and
tho I experimented some minutes the cylinder did not budge to
rotate. A few swaying motions kept up all the time showing_
that air currents could make it vibrate, but not the slightest
rotatory motion occurred.

I had some experiments with Mr. Prescott F . Hall with a
paper cylinder which we made for the purpose. He succeeded
in getting it to move from left to right one time for eleven and
one half revolutions with fair rapidity, but at other times it was
capricious, and would not work at all. Occasionally it might
move slightly either way, just enough to make us uncertain of
the cause. I tried it without any special effect, tho it rotated in
both directions at different times, but slightly and tho I could not
prove air or thermic currents, the evidence for anything else was
inconclusive, tho I do not mean to imply that there was evidence
of air and thermic currents, for there was no such evidence
whatever. Rapid movement in the room some feet distance produced
air currents that caused slight rotatory action on the part
of the cylinder, but nothing systematic. I tried also to produce
such movements by electrifying a sheet of paper, but totally
failed, tho I succeeded in causing the cylinder to sway toward
the paper as attracted by the static electricity, but I could not
produce rotatory motion as I had done in my own room and
when Dr. Strong was present.
To test the influence of electric currents on the cylinder we
put on a current of a million and a half volts, with a machine
