ers who tried the board could obtain a registration of
only 2 or 3 grammes.

_4th Series._--Several very successful trials were made in this series
with two ladies as subjects. Both placed their hands on the board
together, and the depressions were of very long duration. In these
experiments sooted paper was placed under the hands of the
experimenters. It was noted that better results were obtained if one of
them cried "Now!" when the board was to be depressed. The desire to
sleep was strong after these trials, and in one instance the subject
really did fall asleep during the experiment! An odd fact which should
be noted in this connection is that no results were obtained unless the
subject _looked_ at the long end of the board while the "willing" was in
progress.

_5th Series._--This series of experiments was attended by a well-known
physician and a psychologist. The light was good as before. From 40 to
50 grammes were registered by the balance on several occasions, the
downward pressure lasting from 20 to 30 seconds. Clearly, therefore,
none of these depressions could be attributed to mere oscillations of
the board, but denoted a definite and persistent downward pressure.

Nausea and a strong desire for sleep were experienced by the subjects in
this series of experiments, as before.

The above is a very rapid summary of the report drawn up by Dr. Sydney
Alrutz, and read to the Sixth Psychological Congress, which met at
Geneva in August 1909. Professor Alrutz also attended the Congress in
person, and brought with him one of his instruments, which he desired to
try upon some of the members in the presence of a number of
psychologists. In several instances these attempts were entirely
successful; and Professor Flournoy, editor of the _Archives de
Psychologie_, was enabled to say of these experiments:

"Professor Alrutz invited me to assist in two seances, in which we
experimented upon some of the feminine members of the Congress who
desired to try it. The first, in which the subject was Mme. Glika,
yielded nothing conclusive. But at the second, at which Professor
Alrutz attempted to increase the force by adding two other members
of the Congress (strangers who had appeared to him to possess
suitable temperaments), it succeeded fully, and I was able to prove
conclusively after three trials, and under conditions precluding
all possibility of fraud or illusion, that the will
