means of testing the nature of the air currents in the room and
hence they were not excluded from the case, but if the rotatory
motion had been like that last night I should have been more
puzzled than I was with the phenomena. I had the pin resting
on a dime piece as before.
I tried the same experiment after breakfast except that I put
the book between the window and the cylinder and at first used
only the whetstone. No motion oceurred. But as soon as I put
the dime piece under it the cylinder began to rotate and would
alternately make complete revolutions bOth ways. Why it would
not do this without the dime piece is not clear.
I tried the experiment again at noon with the book between
the cylinder and the window and without the dime piece on the
whetstone. But no motion occurred. I then put the. coin on top
of the stone and only slight oscillating movements occurred of
the rotatory type, but not enough to be sure that any'thing save
air currents were involved. I then electrified a sheet of paper
and could give the cylinder rotatory movements quite easily. I
then tried my hands after removing the electrified paper and
after a pause of some thirty seconds or more the cylinder moved
one and a half revolutions from right to left and stopped. After
a pause it moved half a revolution from left to right and then
back to its place, when it paused again. It was well balanced on
the coin. I could not be sure that air currents caused the motion.
In the afternoon I tried several experiments. First I placed
the cylinder on the stone and it would do nothing. I then tried
the coin in place and the stone on top of a wooden box. But I
first tried to see what effect my breathing would have on it. I
breathed through my nose rather vigorously and it produced no
rotatory effect. It merely made it waver a little from side to
side. The object was to avoid producing a direct current of air
on it. I breathed rather heavily and it was perfectly clear that
such currents would not account for the rotations that I have
recorded. All the time there was one book between the cylinder
and the window to shut out the cold air that might come directly
to the cylinder. After first trying breathing without a book between
myself and the cylinder I placed the second book so that
no current from my breath could reach the cylinder. No effect
